Ok, I'm not sure if this is am AMP issue or not. The travel charger w/ USB cord that comes with the Skyrocket is part# ETA0U80JBE. It has a 1.0 AMP charging capacity. Most other chargers only have a 0.7 AMP capacity. It seems odd that both the AT&T store and Samsung's own website lists the extra / replacement charger for this phone as one that only handles 0.7 AMPs? Most other places also list 0.7 AMP units as being compatible units. However, if you search by exact part #, there are a few places online including Amazon.com and Ebay that sell the ETA0U80JBE 1 AMP units. They are made by Samsung (they have the Samsung name on them) and they look and have the same specs as the one that comes with the SkyRocket.

It seems many (if not most) people that are having the 100% battery issue are using chargers that only deliver up to 0.7 AMPs but the people that use the chargers that came with the phone (1.0 AMP) do not have the problem. The 0.7 AMP chargers work, but I can't help but wonder if they are what is causing the issue. I thought it might be a problem related to the overcharge protection and it still might be. Or it could be a combination of the lower AMPs and the overcharge technology. However, if the overcharge detection ciruit is located in the phone itself, it shouldn't make a diference. If the overcharge circuit is in the charger itself, it might be part of the problem with the lower AMP chargers or chargers that do not have overcharge protection.

I am ordiering one of the ETA0U80JBE 1 AMP chargers from Amazon.com just to have a spare. It will be interesting to find out if anyone can identify (without a doubt) what exactly is causing this issue and how to fix it. The lastest OS uprade for the phone did not seem to address it.

Angry Dead overnight...

Just ran across this forum while googling for Skyrocket battery issues. I have had mine since 01-Dec. On Saturday evening I plugged it into the charger that came with it and the display said "fully charged" or something like that so I unplugged it. Sunday morning it was almost dead. Did a full re-charge and no problems till today. When I left the house this morning icon showed full battery. Just went to us it and all I get is a buzz when I press to light the display. This is irritating for a six day old phone.

I'm having this issue as well and its pretty annoying. I had been using my stock wall charger and bought a mini-usb cable from monoprice.com to charge while I'm at work. I used the non-oem mini usb at work to charge, then charged it at home that night using the stock cable and block and woke up the next morning with the battery full issue. Coincidence or not, I don't know, but after a week of a working battery meter, then to suddenly the 100% full battery indicator all times, I think it was the non-oem cable that screwed me.

Is this something that would be taken care of under warranty through the manufacturer? Whom should we talk to? BB or Samsung?

Yesterday evening when I got home I decided to do things a little more methodically. I noted that the battery icon was showing battery fully charged. I then opened the phone and unplugged the battery. On re-installation and power up icon now showed about half. I loaded Battery Solo Widget. BSW showed 52%. I put it on the OEM charger (#ETA0U80JBE) which is 5.0V at 1.0A. By the time I was about to go to bed the phone had reached 100% according to BSW. I repeated the battery removal procedure and it still showed 100%. I dimmed the display and went to bed. This morning after six hours sleep for me and the phone BSW still showed 100%. I repeated the battery removal procedure. BSW now showed 74%. WTF! Zero usage but a 26% drop in battery charge. I recharged it to 100% before leaving the house. Now at work two hours later it shows 98%. I am going to monitor charge till lunch time then repeat the battery removal procedure. Then likewise for the afternoon. I will report again this evening.

I just exchanged my 3rd Skyrocket for a white one...after having the issue on the first Skyrocket I was unable to replicate this issue on the second and third.


I will try on the white one when it arrives

No change to phone behavior till I changed my charging behavior. I used to unplug from the charger a little while after reaching full charge. Not being electrically knowledgeable I am afraid I will burn up the phone, battery, or charger. But that's my problem. The other evening I plugged in to charge then forgot and went to bed. Phone got a good eight(8) hours charge. Yesterday power consumption was much slower and more palatable with what I expect from modern technology. I am going to try to follow this routine for a couple of days and take notes. To be continued, M

The issue here is clearly a charger issue. It is not going to be affected by the cable, so anyone wasting time with that theory... stop. I am an Electrical Engineer and have worked on this type of stuff at the IC level. While I dont know exactly what Samsung has done here, I can make a pretty educated guess. The wall plug has a 'chip' in it. That chip is very specific (in that ALL the ones sold with this phone, and probably most of their phones have the same one). A few manufacturers make them and this is the one Samsung chose to use, and it probably has some programmability - or sends some specific signal to the phone when it is charged. OR it is possible the phone detects something in the charger unit OR the phone sends some acknowledge signal to the charger and if it doesnt receive back a specific signal it dont 'play happy'.

Given the quick-charging nature of the phone, it is likely this is a fairly newer USB chip in the wall unit - and it is a little buggy. But that functionality could also be in the phone, which is also buggy (Samsung is NOT know to make the most quality product - and in fact they are such a bad company that any engineer I know who has ever worked with them refuses to EVER own one of their products... I almost didnt buy this phone because of it, but I still like it better than the current alternatives, so...)

I have had this issue with my 2wk old Skyrocket a few times. Full charge. Let it sit 3 hrs. Dead. Also partial charge and dies very quickly. Also full charge but pull battery and it reads correctly (ie 30% down or whatever). I would expect there to be a fix sometime as this is a pretty big issue, but it is also POSSIBLE there is no simple fix... just depends on how they made the phone. But given a reboot works there should be a simple fix. So I am being patient because as much as this issue REALLY PISSES ME OFF (to the point that I am very close to ditching this phone for an iphone) I am willing to wait it out because I like the phone enough to deal with it.

In any case, it appears that if you charge with the OEM wall-wart, or battery-out reboot, it seems to behave properly. If anyone knows of an app that correctly tells the phone % battery left in the notification area I would very much love to know about it.

It's even simpler than what you suggest. The 5v 1a chargers are causing the issue...one of us just needs to take the time to verify the theory. The .7a chargers do not cause the issue.

Mad 2nd Skyrocket, same issue

I have the 100% indicator issue too. I returned my first Skyrocket because of that and the fact that it was crashing during games (the crashing problem disappeared after the last patch). The new phone had the same battery indicator problems. I used the battery and charger that came with the phone. I always charge overnight, and I really have better things to do with my time than stare at my phone and see if it's charged or not, so unplugging it right after charging really isn't an option.

Also, I called Samsung, and they claimed that no one had called them before for this issue. So I would ask that everyone call, so we can get some attention on this issue. 877-392-4252 is the number. And their answer was to factory default the phone, and if that doesn't work, send it to them for repair (yeah right).

The stock charger is a 1a charger in most cases. A few have posted receiving a .7a charger.

When I use the 1a charger the problem happens (trying to verify on a 4th and 5th skyrocket tonight)

When I use ANY of our other chargers, all of which are .7a, the problem does not occur.

Check your charger, is it 1a?

Just when I thought my problem was gone the phone showed me how wrong I was. After overnight charging Thursday into Friday both the battery monitors (icon and the app one I installed showed 100% charge till past lunch time. I of course did not believed it and removed and re-installed the battery. 71%! Expletive, expletive.

I guess it's time to try the .7A charger theory. Any suggestions on which one I should source?

My battery indicator light has not shown this issue again since doing one thing. Removing the battery for a bit then reinstalling BEFORE charging one night. Since then, 7 days ago, I have not seen this issue reappear on my SR. My battery meter displays as it should. I mainly stick to using the OEM cord/block for overnight charging. It is rated at 1.0a.

I wish I did, we have a ton of them lying around the house so I have just been using those. Some are HTC branded, others Samsung.

I am not entirely certain the issue is the charger now. It may be the phone. I am continuing to test, but in my testing last night I could not get this to happen again on the new phone.

i.e.

I used the 1a charger that I suspected to be causing the issue to test my new white skyrocket and I can not get it to do this. The battery meter works every time so far.

I am going to leave it on the charger for a few hours today at 100% and see what happens.

Yesterday afternoon I got the store I got my SR from to lend me a Samsung ETA0U60JBE .7A charger. That evening I removed/waited/reinstalled battery then charged to 100% with it. This morning eight hours after charge according to the monitors the phone had only used 10% of the charge while it and I slept. This is much better than the 26% I reported a few days back but I am still skeptical. To be continued, M

I have no new news.

Left both of our phones charging 8hours at 100% on the .1a chargers last night and both are displaying battery correctly.

This may indeed be phone specific and the .1a charger is simply the trigger The question at that point will be is it software phone hardware or battery

Somewhere around 30 hours since .7A charge and battery indicators show 67% battery left. Encouraged but still skeptical! I am not going to recharge till phone stops working. That way I can get a better picture of indicators verses function. The story continues, M

Last night before sleep my battery indicators showed 30%. This morning they still showed 30%. Went through the battery removal/wait/reinstall and the indicators showed 0(zero)% on power-up. A few moments later 1%. An hour later as I was leaving for work and the phone had just been sitting not being charged I saw 17%. When I got to work 15 minutes later it was still at 17%. Switching to the .7A charger seems to have made things much better but not completely fixed. So as a previous poster said it is probably a combination of quirks that is making use of the 1.0A charger impossible. I am going to continue to monitor for a couple of days and report observations here. M

Mine has worked perfectly for 11 days, but under the FWIW catagory - I have read that the original GSll had a problem with battery usage and slow charges. I wonder if that phone used a .7A wall charger and charging circuit, and if the S'rocket got the same internal charging unit that was designed for .7A, and they just threw a 1A wall charger at it under the old theory that if it doesn't work, hit it with a hammer. If it still doesn't work, get a bigger hammer.

Another thing you might try if you continue to have problems is an iPhone charger. It is 1A, and the QC may be better, or the Kindle charger is, I believe, .75A.

the apple 1a charger is what gave me issues on my previous skyrockets. I have been using it for the past 4 days now with no issues (different skyrockets now)

Just when I am starting to get a good feeling the problem is workable even thought not gone the phone again proves me wrong. Charged with .7A unit to 100% last night only to find it was down to 84% just sitting there while I slept for 6 hours. Plugged in to same charger when I got to work till the phone told me "fully charged" or something like that and to unplug charger. By the time I left work 9 hours later and only making one phone call on the phone the battery was down to 37%. This is BS! Phone is getting exchanged as soon as I can get to the store where I bought it. I hope I don't have to go through 4 or 5 phones to find one that works correctly. Other than the battery bs I really like the phone.

Plugged in to same charger when I got to work till the phone told me "fully charged" or something like that and to unplug charger. By the time I left work 9 hours later and only making one phone call on the phone the battery was down to 37%. This is BS! Phone is getting exchanged as soon as I can get to the store where I bought it. I hope I don't have to go through 4 or 5 phones to find one that works correctly. Other than the battery bs I really like the phone.

I can appreciate your input but I don't think you are having the issue we are discussing. We are referring to charging then the battery level indicates 100% the entire time it discharges. Your complaint appears to be battery life related.


I have had my new skyrocket a week now and the issue has not been present/regardless of charging method used fyi

I got a replacement SR 15-Dec. Still using the same 1.0A charger that came with the first SR. No quirky battery life problems at all now. The problem was either in the first SR phone or its battery. Now I can move forward and enjoy the phone.

The unnoficial answer is bad firmware in the battery. The 1a charger triggers the issues. Contact your carrier or Samsung for a new battery.

AT&T acknowledged that they believed it was the firmware in the battery, hadn't been confirmed by Samsung, but they were honoring it was a warranty exchange. The firmware in the battery and NFC chip are the culprits for this issue. Others have had the issue resolved by getting a new battery from Samsung. It does not appear to be related to the chargers for users that experience it from the first use of the device. For others that have not had the problem from first use of the device with the provided Samsung charger, it can be reproduced with use of other branded chargers, such as the apple chargers.

For the first time since exchanging phones two weeks ago mine acted up overnight. Similar to once before in that battery showed 82% before I went to sleep and then 31% seven hours later when I got up. Reading Mr. Ed's post from yesterday was an interesting coincidence. Is there any way to identify which batteries have the "good" firmware in them? My current battery shows EL-L1D7IBA and S/N:NA1BA31DS/4-B.

So, am I missing something or is this the same thing that you all are seeing? I'm now understanding that this is not normal and i should ask ATT for the battery to be changed? Or, are your issues different?

I believe yours may be a different issue. The stock battery meter displays 15% incremental changes ...i.e. you won't see the meter change until it reaches 85%

In the cases above the battery level never changes until battery pull, or it dies

First: MWFRELS: Your issue is not the same thing that the rest us us in this thread are talking about. You are throwing out all kinds of different battery level numbers. The only number we are concerned with in this thread is... 100%

Second: I bought my Skyrocket on the 21st. I brought it home, opened the box and was instantly unimpressed with the length and flimsiness of the charge cable. I immediately ordered 2 high quality MediaNet 6' MicroUSB cables and an OtterBox Commuter case. I then spent a week waiting while using the normal routine I have used for a couple of years. I have a Belkin dual port charger by my bed. 2amp, 1amp per port. I charge both my phone and my 64G iTouch overnight while I sleep. Everything was fine for a week until the cables arrived. First night on the much nicer, heavier, and most importantly.... longer MediaNet cable, I awoke to the 100% battery stuck issue. The next three nights in a row resulted in the same thing. Last night, I switched back to the stock cable. This morning... no 100% battery stuck issue. I only have one day of testing to base this opinion on but FOR ME... the issue appears to be what cable I use and has nothing to do with the charger (theory disproved, definitely a combination of the two). I did absolutely nothing else... no pulling batteries, no change in software. The phone is completely 100% stock with the apps I pretty much installed all during the first two days of owning the thing. The only thing that changed... was the cable.

This is my composite testing chart.
It containing results from all posts that follow.


--------------------------------------------------------------------------------------

All testing done with Belkin dual port charger, 1amp per port, charged overnight for about 8 hours:
12/27/11 - 3' AT&T Zero Charge Cable/Belkin Dual Port 1a/port charger - No problems to date
12/28/11 - 6' MediaNet Cable/Belkin Dual Port 1a/port charger - Stuck battery indicator - first time
12/29/11 - 6' MediaNet Cable/Belkin Dual Port 1a/port charger - Stuck battery indicator
12/30/11 - 6' MediaNet Cable/Belkin Dual Port 1a/port charger - Stuck battery indicator
12/31/11 - 3' AT&T Zero Charge Cable/Belkin Dual Port 1a/port charger - No problem
01/01/12 - 3' AT&T Zero Charge Cable/Belkin Dual Port 1a/port charger - No problem
01/02/12 - 6' MediaNet Cable/Belkin Dual Port 1a/port charger - Stuck battery indicator
01/03/12 - 3' OEM Cable/Belkin Dual Port 1a/port charger - Stuck battery indicator (8:45)

The end of testing with this specific Belkin charger tells me I get very consistent, predictable results with three different cables. Only one of the three cables (AT&T ZERO Charger) charges properly with this charge block. My initial results tell me it's not a matter of one or the other (block/cable) but a combination of the two.

--------------------------------------------------------------------------------------

All testing done with an HTC wall adapter, single 1amp port, charged overnight for about 8 hours:
01/04/12 - 6' MediaNet Cable/HTC wall adapter, single 1amp port - No problem (9:15)
01/05/12 - 3' OEM Cable/HTC wall adapter, single 1amp port - No problem (9:00)
01/06/12 - 3' AT&T Zero Charge Cable/HTC wall adapter, single 1amp port - No problem (8:00)

--------------------------------------------------------------------------------------

All testing done with OEM wall adapter, single 1amp port, charged overnight for about 8 hours:
01/07/12 - 3' OEM Cable/OEM wall adapter, single 1amp port - No problem (8:30)
01/08/12 - 6' MediaNet Cable/OEM wall adapter, single 1amp port - No problem (9:15)
01/09/12 - 3' AT&T Zero Charge Cable/OEM wall adapter, single 1amp port - No problem (8:30)

--------------------------------------------------------------------------------------

All testing done with Scosche reVIVE II, dual 1a/2.1a ports, charged overnight for about 8 hours:
01/12/12 - 3' AT&T Zero Charge Cable/Scosche wall adapter, dual 1a/2.1a ports - No problem (8:45)
01/13/12 - 6' MediaNet Cable/Scosche wall adapter, dual 1a/2.1a ports - Stuck battery indicator (8:00)
01/14/12 - 3' OEM Cable/Scosche wall adapter, dual 1a/2.1a ports - Stuck battery indicator (8:00)

--------------------------------------------------------------------------------------
01/01/12 - It appears that the cable I have been using since buying the phone which does NOT result in the stuck indicator issue is the aftermarket cable I bought from AT&T for $9.99. It's part of their ZERO Charger system. It has the little black tag on it which says "Charge only Cable." So, I have apparently never used the OEM cable. Chart revised

01/05/12 - I discovered, in another thread concerning USB data connections, that the aftermarket, AT&T ZERO Charger cable I have been testing (along with two others) which has NEVER resulted in a stuck battery indicator, is marked as a "Charge only Cable" on its little black tag. It does NOT work for data connections but reliably charges the phone without the issue at hand... so far.

01/07/12 - Doesn't seem to be much point continuing with the HTC charge block tests. All three cables charged the phone reliably once. In the interest of expediting other charger testing, I'm moving on to the OEM charger tonight. I may come back to chargers that only got one test per cable later, but my first try at multiple tests of individual cables yielded consistent results. One specific cable never performed differently a second or third time.

01/08/12 - The $64,000 Question. OEM charger, OEM cable, no stuck battery indicator (for me). The OEM cable has performed fine on 2 out of three charge blocks I have tried so so far. The only one it didn't like was the Belkin, but the Belkin was fine with the Charge Only, AT&T aftermarket cable.

01/12/12 - Starting testing of a Scosche reVIVE II (USBH3) Dual port (1a/2.1a). The 2.1a port is for charging iPads which I don't own. Should be interesting. I bought this for my son after I gave him a 64G iTouch so he could charge his phone and iTouch at the same time like I do with my favorite little Belkins. I never gave it to him out of concern over the 2.1a port. The thing had great reviews when I bought it, now everyone is screaming mad. There are allegations that it doesn't meet certain standards and they all seem to drop dead within a couple of months. Great stuff to test with I won't be using the 2.1a port.

http://www.amazon.com/Scosche-reVIVE-Dual-Home-Charger/dp/B003N7NO4G/ref=sr_1_29?s=electronics&ie=UTF8&qid=1326445451&s r=1-29





This cable with this little black tag saying "Charge only Cable" and marked "AT&T" on the full sized connector does NOT work for USB data connections. Beware. It does, however, faithfully charge the phone on every charger I have tested without triggering the stuck battery indicator issue. This includes one charger that won't properly charge with any other cable.

^this is interesting. A handful of us tested numerous cables and always resulted in it being the charger

It makes very little sense unless there is a physical difference in the cables. I suppose I could get out my continuity tester and start probing individual lines. Having spent most of my life in the audio/video business, I know better cable allows better conductivity but I can't see that being an issue. I'll switch back and forth between cables for the next week or so and update the original post in the morning with my findings using both cables.

It could just be a random problem.

Original chart updated. Night 2 on the stock cable/belkin charger, no stuck issue. Tonight I will go back to the 6' MediaNet cable.

Yesterday I barely used the phone. I played with the camera for about 10 minutes in the middle of the day. Checking the usage chart just before plugging it in... I could see a very slight, continuous slope with a little bit of a fall off right in the center where my camera usage would have been. After 16 hours off the charger, the battery was still at 81%. I plugged it in at 3:30am and heard the "charged beep" 25 minutes later at 3:55... I let the screen die off by itself and left it on the charger till I woke up at 1pm today.

The day I bought the phone at AT&T, I bought a second, aftermarket cable AT&T had on a rack. It looks about the same as the OEM. Flimsy and only about 3' long. I have never used that cable. I'll toss it into the testing mix eventually.

I also have a dozen different blocks lying about including an Apple, a couple that came with my Jawbones, a new, never used Scosche that is a dual port with a 1amp and a 2.1amp port. The 2.1amp is for charging iPads and, presumably, other tablets. I'm not sure I want to put my phone on anything with that much amperage but it shouldn't harm anything. A device will only draw what it can.

EDIT: It appears that the cable I have been using since buying the phone that does NOT result in the stuck indicator issue is the aftermarket cable I bought from AT&T for $9.99. It's part of their ZERO Charger system. It has the little black tag on it. The tag says "Data only Cable", you cannot use this cable for USB data connections. So I have apparently never used the OEM cable. Chart revised.

Used the 6' MediaNet cable last night and had the battery stuck issue. Seems an open and shut case between those two cables on that charger. Will try the OEM cable for the first time tonight. Depending on results, I'm going to move on to different chargers. Chart in original post is updated.

I was also having the issue of the meter being stuck @ 100%. I had tried the stock charger, a usb style charger for iphone and both had same results. Stuck at 100 unless I cycled the phone off and on. Then I came across a charger that I got with my BB Storm a year or so back, tried it. Voila, no more issues of the meter being stuck at 100%.
Just my "2 cents"

Using the OEM cable for the first time tonight, on the same Belkin charger I've been testing the other two cables with, resulted in the battery stuck issue. That's odd. The cables are nearly identical. Same 3' length and flimsy guage of wire. Could be the best way to avoid the problem based on my results is to buy one of the $9.99 NET Zero charge cable from AT&T. You don't need the block that is sold separately. I'm beginning to wonder if time on the charge is relevant and will start keeping those stats.

Switched up chargers last night. Now using an HTC wall charger with a single 1amp port. 6' MediaNet cable resulted in no problem unlike with a Beklin charger. Chart updated. Charged 9:15.

Thanks for trolling. This thing has a perfectly fine working battery meter. If you're like many of us who like/need to charge from several locations and tend to use multiple types of charges and cables, there can be issues. Now please step back to your iPhone

When using the OEM charger, did you use the OEM cable? What does the output amperage stat on your OEM charger say?

"This thing has a perfectly fine working battery meter". Apparently not, important enough to make a sticky about it.

I'm not trolling, my point is............. 5V is 5V. Feeding it a max of 1 amp or 3/4 amp should not change a thing regarding battery indication. Slight voltage and resistance variations exist from charger to charger and if the system cant account for these common variations, then its a crappy design. Since I have a Skyrocket, it does concern me.

Lets all try and keep it civil and work towards the common goal

Midiman is making great progress with his chart


What I still can not understand is this:

My previous skyrockets had the issue, current skyrocket does not

I am using the same chargers that I used previously

You are correct, 5v is 5v, however feeding at lower amperage than a device will attempt to draw will result in overheating a charge device (even a battery) which can lead to all sorts of irregularities including the death of the charger. That's why we don't put AAA batteries in slots designed for D's despite the fact that they are both 1.5v devices and the end terminal spacing is the same. Conversely, feeding at higher amperage, within reason, has no ill effects and just makes the charger more comfortable and efficient. For instance, I frequently power guitar devices that require 100ma with 2amp supplies but wouldn't care to put a 200amp supply on them. I no longer have access to the fancy kind of diagnostics gear I had in the engineering dept of the PBS station I worked for (please note, I was a producer and director, not an engineer... but once you're in the field, you become a bit of everything). That sort of stuff would monitor voltage over time, looking for irregularities so you didn't have to sit and stare at a display all day. I have only encountered the problem with one out of three chargers I have tested so far. I'll stick a VOM on that one and see if I find any discrepancies between published and actual output levels for voltage. Perhaps I can persuade an old friend who still slaves in the dept to toss the thing on for a while and see if he can come up with anything.

That said, I've found a couple of 550ma USB wall adapters that came with my Jawbones. I'll get around to testing one of them to see how a substantially lower amperage unit does. I know Samsung seems to sell an adapter for the Skyrocket rated at 700ma. Odd since the OEM supplied with the phone is 1a.

Unfortunately, for me, the Belkin charger is the one I like. I like it so much, I bought two and they functioned fine for the two year life of my HTC Tilt2 and everything else I've thrown on it. I like to be able to charge both my phone and iTouch at the same time, with a minimum of fuss and gear, in multiple locations. One stays in the bedroom, the other is usually at my main (one of four) workstations in the house. Of COURSE... that's the one I have issues with. Fortunately, the issue is avoidable by using the AT&T "charge only" cable in the bedroom. I don't need a data connection there. Unfortunately, the cable is only 3' long which makes it difficult to grab and answer the phone while it's connected. I might do some testing with a USB extension.

There has been one member on FDA that claims he was told it was bad firmware in the battery.. battery was replaced and the issue went away. Can you update us when you try the new battery?
