about 5-6 short shallow charges (charges before or at around 40-30 i would say) = 1 deep charge (if you drain the battery completely and then recharge it).. That is why on lithium-ion polymer cells (especially single cell design like our phones) you DO NOT want to discharge completely...

Default Battery Fix For Good

Why doesn't some genius invent a nuclear power chip for these power hungry devices? Imagine...2,000 years before chip replacement.

Why Not??

My phone is still new but this is what I discovered, the first full day owning my Moment I took it off the charger at 6am and by 10am it was about to be completely dead ...

That night I worked out some issues with Sprint tech (my phone wasn't fully activated if you can believe that) and change a bunch of settings which included:

Brightness all the way down
GPS Satellites Off
Data Roaming enabled
Sprint Service in Automatic (Sprint/Roam)
Wifi Off
Gmail set to manual retrieval

The only things i have installed so far are
Battery Gauge
Quick Settings
Weather Home Screen Widget (large) set to my zip code only

Today after a full charge last night its 3:50pm and I am at 80% still!! I would say thats a huge improvement - will see if its consistant -

I see your point.....carrying around a small mobile nuclear device that could get run over and is guaranteed to get thrown in a landfill within a couple of years....Brilliant!! Not to mention it is a great way to guarantee our kids have 2 heads.

On a serious note...yeah, the whole battery technology thing needs to step it up and fast!!

YEAH - My battery problem is solved

Like most, I've never been really happy with the battery life on my Moment. I did all the normal settings, e.g., turn off wi-fi, turn off gps, set the screen brightness to low, updated to cl14, etc., and it was better, but never what I thought it should be. Then about a week ago my battery started to die after just a couple of hours. I doubled checked all the settings and nothing had changed. I removed the last several apps I had either installed or updated but that did not fix the problem. Then yesterday my phone would no longer sync with my work Exchange server. I checked the Moxier settings and it kept giving me errors when I would try to save the settings. I eventually deleted my profile and set it up again. After a full charge, my battery reads 100% after 1.5 hours. For any normal phone that would be no surprise, but for this phone I'm still in shock. I don't thinks it's ever shown a full charge this long after unplugging it in the 6 months I've own it.

Obviously this is not going to help everyone, but I thought I would share.

Yeah it is always a good idea to make sure anything that syncs is working properly. I don't sync anything but Moxier and I make sure I always update it. Yahoo i only sync the inbox. everything else stays off.

Well it's been 10 hours since I unplugged it and with light usage, e.g., 30 minutes talking, 15 minutes web browsing, 20 minutes composing emails, syncing all day with Exchange, gmail, and a second gmail account, it shows 15% remaining. I know there is more because of the well documented issue of the phone not reporting the battery properly, so hopefully I'm back to "normal" battery problems. I don't feel like rooting so hopefully the 2.1 update will fix the battery meter issue.

Well being the owner of the moment from day 1, like most the battery is horrible. Well a few days ago, the wifi stopped. Other then that...I had to at least once a day restart the phone. So I took it to a sprint store. An hour later they did a hard reset and there was the wifi networks...great so I left. From the time I left the store to home was like 10-15 minutes.

During that time I had to restart the phone 2x and each time take the battery out. Got home and wifi stated unable to scan for networks. grrrr...So went to another sprint store and let them know. I was told if the other store could not fix it as they were a bigger store they would just order me one.

I got it the next day and it had the cl14 updates. I don't know but I seem to get much better battery life now. Now the thing is the "new" phone I received was a refurbished one and was told that the only thing that was refurbished was the sn#.

But funny thing is that when I called sprint, I explained to the rep from tech support and explained about the wifi I

Sad thing is that I had the invisishield cover on the phone and now that is gone. Not paying for that again.

I just got the Droid Eris for Verizon today and drained the battery completely dead before charging it. I have been charging my phone since 6 o clock and its not 12 o clock and its only at 39%.I have it hooked up to the wall outlet.

I have been using it off and on while its been charging. I've been adjusting apps, lowered the brightness, turned off wi-fi, turned off gps.

Whats going on here? And why won't this thing charge? I even used the task killer to make sure no apps were running in the background.

Well, maybe if you had chosen the Samsung Moment over the Droid Eris someone in this forum could help you.

How about here... Droid Eris

Question i220 extended battery for Moment

Ok..went here: Samsung i220 Code Cell Phone Accessories and Battery and ordered a 1600 mah i220 battery compatible with my Moment, Behold II, and Instinct HD....fit perfectly, without the need of a extended Moment back cover...worked fine, got an occasional message that the battery is not approved..when I went to charge it, the phone gave me the message, "not an Approved Battery", and shut down...

Is this why there are no third party extended batteries for the moment?

Are there any firmware work-arounds for this error message?

I have screen brightness at 20%, GPS off unless I need it, wifi off unless I need it and use my phone normally - sending texts, emails, searching for signal while I'm underground, surfing, downloading apps, talking on the phone, and after 12-13 hours, I still have 10% left.

anybody noticed since the 2.1 update that it munches battery like a hog? it'll say full charge and six, maybe 7 hours later im down to 15% or less. and this is when im at work, where im not even allowed to use it. so it sits in standby and still destroys the battery in such a short time. i've have to start taking my charger everywhere i go. i have ATK set to autokill unused apps every hour and no change. no live wallpapers, but i do use launcher pro. any ideas?

yeah I've been having the same problem with my phone -_-. ever since the 2.1 update the phone drains the battery like crazy; i don't even touch my phone at school and it is down to like 50%; only if i don't put it on airplane mode it does that, on airplane mode it is still at 90-80% after i get out of school. i use launcher pro as well and i saw on the comments that it consumes a lot more battery but i can be wrong but thats what i saw; ill see what happens when i use the regular home screen thing after i drain the battery completely today.

Notsure Samsung Moment Battery Issue with 2.1? / Solution App?

Hello All,

I hope I'm not reposting but I couldn't find anyone that had expressed the same issue I'm having with any solutions.

I bought my Moment about 6 weeks ago. The first few weeks I was running the default 1.5 software on it. I had no battery issues and no lag. I could go through a day of moderate use on a full charge.

After my recent upgrade to 2.1 I've noticed the phone lagging (on occasion), and my battery life is...well it's crap. I can't use it more than a couple of hours before needing a recharge.

I disabled GPS and set the screen to auto brightness just as when I was running 1.5.

I've tried task killers with no success. I've currenly installed JuiceDefender hoping it will help a little.

- Has anyone else had this issue?
- Does anyone know of an application that will help save the battery?

I really like Android and my phone, but that means little if it is turned off due to a dead battery!

Thanks,

-P

----Original post follows ------

The spec's sound good, but I wonder about the battery life?

My daughter has a Samsung Gravity and it won't last through a single day -- even after trading it in on a new model.

So, it sounds great that the Moment has a faster processor, lighted keyboard, camera flash, and possibly more. However, is this simply a sign that Samsung isn't sensitive to battery issues or have they really figured out how to do that stuff and deliver a reasonable usage time?

One of the best things you can do for your phone's battery life is to load a custom kernel on it. I can easily get at least two days on a full charge, which is all I could expect of my old Sanyo Katana. Whather you do that or not, poke around here a bit and you'll find a lot of posts suggesting optimal settings for your battery.

Thumbs up Android 2.1 Power Issue / Follow up : JuiceDefender

As a follow up to my post yesterday I must say that the JuiceDefender program has helped quite a bit. Using my phone very minimally it was still at 80% after 10 hours where before it would have been less than 50%.

Just updated to FroYo to my Samsung Moment and battery life has been decreased dramatically. I'm a heavy phone user and a moderate apps user. With OS v1.5 my phone comfortably lasted through the day and in to the evening. This is day one of FroYo and I barely made it to lunch. In checking the battery use app on the phone it says that 82% of the battery life was used by the OS. Ouch !!!! Otherwise so far Does anyone know of a "super" battery for Samsung Moment phones. I love FroYo and I definitely love the phone except for the camera. Lack of a zoom feature makes it worthless even if it is high res.

Is it just me, or does there seem to be a lot less "chatter" in this forum following the 2.1 upgrade??

Default battery not charging

I just exchanged my Samsung moment to get a new/refurbished phone at no charge. The problem was no matter how long I had the phone charging, as soon as I unplugged the phone it would show the battery life at almost zero. After about 4 days, I was lucky if it would even charge. The phone I have now had been on the charger all night, and within a few minutes of it being unplugged, it went right to 80%. All I did was check Face Book for a few minutes.
Has anyone else had this issue with the battery not even accepting a charge and only being able to use the phone while being plugged into the charger? Is there an alternate battery that may have a longer lifetime? Would I be able to plug in a bettery life extender type device?

Just got a Moment last Thursday, and am having major issues with the battery. I am running a custom ROM, the Vampire one, sorry can't remember the name or version at the moment. I have everything turned off that I don't need, wifi, bt, gps, and I have nothing syncing in the background. An example of what's going on: Today I pulled my phone off the charger @ 9:45am. I go into work, send some txts, check some things on the web. I leave work around 12:45, battery still showing full green, come home, make one call on the phone (less than a 5 minute call), then do not touch the phone till just awhile ago, about 3:00pm, and the battery was dead, phone had shut off. I have no clue what's going on, but unless I have the phone on charge all the time, I cannot keep the battery up. I am going to get Spare Parts and see what may be draining it, but any other ideas? I have read all of the battery guides, etc. I have not installed a task killer because I don't think it is needed for Android, and others get along great without one. Thanks!

Default Battery Life

I hope someone starts listening to us. This latest update is chewing through batteries. I can't make it through 1 day with 2 fully charged batteries. This is with limited use of any apps or even phone calls. Time for a new update or a new phone!

As an update, I installed the Overclock Widget from the marketplace, and it may have solved my problems. Full charge @ 9:00am, now it is 3:30pm, and I still show 80% battery. What this app does is lower the CPU speed down whenever the screen is off. I am thinking somewhere I have have an app that is still running in the background, and maybe this at least slowed the CPU down.

I noticed that the "Use wireless networks" location setting in CL14 prevents the phone from going to sleep when the screen is off. This can be verified through the Spare Parts app. I haven't had a chance to upgrade to 2.1 yet, but could you see if that helps in lieu of underclocking?

When that setting is enabled, my phone will drain in 10-12 hours. This weekend I ran 41 hours before charging at the yellow level, with bluetooth, gmail sync, imap hourly poll, gps enabled (but never used), 80 minutes of talk or so, and a couple hours of web via opera mini.

Hi All,

I don't know if this is the right forum for this but...

I have a HTC Desire which I have been using for a few months now with no problems. Today, for the first time, I used it in the car as a Sat Nav. It worked okay but because of my cheap car charger not being able to supply enough current it eventually went flat and shut down.

After only about ten minutes after it shut down, I got home and put it on the charger (official HTC mains charger with official lead). It has been on the charger for about an hour now and it still won't turn on. No lights are shown on the phone (led charge light).

Am I doing something wrong, or is the battery knackered?

Any help much appreciated.

Thanks,

Taf.

One thing I do that has dramatically improved my battery life is charging via USB @ 0.5A. I actually use a Sony PS3 controller charger that has 2 usb ports that plug into the wall I found on clearance at Walmart.

My battery now lasts at least 36hrs. I'm mainly a talker for ~1-2hrs daily mixed with data and some GPS.

Not sure if anyone has stated this but Li-Ion have a usable range of 3-4.2v. 3.7v is nominal. The phone should prevent the battery going below the 2.7-3v or above 4.2v to prevent damage to cells.

@tafka - If you have a DVM you can measure the voltage on the battery terminals. Should be ~2.7-4.2v if its below 2.7 then may be the phone preventing it to charge for safety reasons.

Thanks for the reply. I should have posted, I got the phone working again.

I plugged it into the charger with the battery out, then held the power button in, then put the battery in. That obviously gave it enough of a power spike to start the charging process. It has been fine ever since.

I guess part of the problem is that the phone takes *so long* to shut down. That's a bit of a problem if the battery is nearly flat.

Interesting idea about the ps3 charger though, I might give that a go.

I have now bought a cheap car charger from Tesco that seems to *just about* charge the phone when GPS/Data transmission is running.

I have a question regarding the trickle charger (using a computer usb port)...I usually wait until the phone actually dies to charge it. I always use a computer usb port to charge because I'm usually around one, even at work.

My question is, since it's a trickle charge can I leave it plugged in all the time without affecting the battery conditioning? It is my understanding that with batteries like these (this might be the case with old batteries) it's not good to have them plugged in all the time with the wall charger because it's continuously charging "full force".

Thank you

Default And what were you thinking

Why is it when these "gotta have it" phones hit the market, people are SOOO suprised when it eats the battery. I had the TREO 800W once. Had it 27 days. Took it back. Seemed it just love to eat the battery in 18 hours. Got an extened one about 1 week of ownership. Not much better. Got about 6 hours more use. Oh well, took it back and got the755P treo instead. So, now, using the moment. I think the person who tried to be funny "you only have enough power to use it for a "moment"" was right on. Everyone will post graphs, make desk top tech diag comments and still, after 20 some "suggestions", it comes down to one thing. The phones are battery hogs people. No app, no update, nothing will give you nothing more then hype. I can run through the same morning ritual of turning off everything that will not keep the phone from functioning for its INTENDED purpose of making calls and I still have to start looking for a outlet in about 12 hours if traveling around town, 18 if I'm at home. God forbid I want to download and install then run anything. Hell, it doesn't even make calls well. Big delay dialing to connection. Sometimes, I find myself looking at the phone for 30 seconds or more seeing if I have a darn signal. So, 2 of my kids wanted updates. Guess what phone they DIDN"T get.

I have owned the Moment for seven months.

The bottom line: the phone blows. Running Android 1.5 the phone might last for 4 to 6 hours without any significant use. This wasted down to 3 hours after about 6 months of owning the phone. I upgraded to Android 2.1 yesterday, and I have to say: little has changed.

The phone is set with wifi off, etc., and the battery dies a miserable death without any use of the phone -- almost instantly. I am a big Samsung booster -- own a laptop and two laser printers made by them. But the moment is a joke -- it's untenable for just about any user around. Unless you want to have your mobile phone plugged into a wall socket 24 hours a day, you should ditch it if you can. I am going to imminently.

The phone is just not worth the aggravation . . . .

I completely agree with you. I switched to a Samsung Moment from an older Palm Centro. On days when I use the Moment almost exclusively for talking, with no texting, web-browsing, apps, etc.--I still can't get through the day without a charge. With similar use, the old Centro could last three or four days. I find this very irritating.

It's not worth it. Having ATK running all the time and killing applications on a schedule, uses up the power that you save by killing the applications. If you're going to use ATK or any other app killer, set it to kill itself and use it manually after a restart and shut down those programs that don't automatically restart themselves.
