When I am at my country house, I have no service. If I leave my phone alone, it will suck the life out of my battery very quickly. I put it in "Airplane Mode", which turns everything off. Then I go back in and turn on my WiFi, as I have that at my home. I can go to my "Talkatone" app and use my phone over the internet and my battery is ALL GOOD. I still get my emails, but texts and sms do not come through until I go to town with "Airplane Mode" off.

I seriously doubt everyone that has problems boils down to the idea that: it's 2012 smart phone, so of course it must use lots of power. That and there being so many bad batteries out there. I am thinking you are just turning 4G/3G off on to conserve your power since it was only active for 40 minutes out of 9 hours. That will make a big impact.

For me, leaving the radio on takes up about 40% of total usage according to GSam (keep in mind in my city I get 4-5 bars for 4G constantly and WiFi is usually 4-5 as well). Have a few friends and they all have similar results with the radio at least.

However, the radio isn't the biggest problem. I lost 21% in a total of 2 hours with just sending 5 texts. See attached images. I am not sure why the kernel is consuming so much battery. Anyone have ideas?

So I check GSAM

88% of that 1% is attributed to apps... so onto the apps...

Android System is responsible for 51% of that... so onto that...

I feel this is the most important snapshot of the series. This reveals the wakelocks and whatnot

The above is a snapshot of the setting's battery usage thing built in

I'm noticing my phone wasn't awake during the night according to this lol. I like this!

Here is a different snapshot of Android system. I like GSam's better

Anyway, that's the results. What's the next step? What do these pics reveal?
Hmm.. not quite what I expected. From what you've described,it seems to indicate it's related to the radios somehow.

You could try disabling LTE, however this will lock you into 3g/4g HSPA+ and would not fall back to EDGE if you left a 3G area, but this would be done more to diagnose the issue rather than a permanent solution:

[How to] disable LTE on AT&T S3 (you can disable HSPA+ too) - Android Forums at AndroidCentral.com

You could also try leaving Airplane Mode OFF, and just turning the data off and see how that changes.

There is a fix over at XDA for the standby issue (it changes a file value from 34 to 3.4), but requires a rooted device (Don't have the original link atm but have the instructions saved in notes):

On the XDA Developers forums, boasting the largest community of application developers and smartphone hackers, some users posted that the battery problem stems from the Galaxy S3's standby feature. They said the file on the smartphone that contains the drain value was wrongly set when the device shipped. This file, known as the framework-res.apk, was set at 34mA when it should have been set at 3.4mA.

For an owner of the Galaxy S3, this means the phone may incorrectly display a 50 percent to 70 percent battery drain, as Auto-O-Mobile has pointed out.

Users experiencing this problem can fix it by changing the power_profile.xml file located in the framework-res package. To do this, complete the following steps:

-- Download the updated file (510kb) from MediaFire. http://www.mediafire.com/?x7lhcpjjr9pg4mb

-- Save the file on your microSD card or internal storage.

-- Reboot your Samsung Galaxy S3 into ClockWork Mod (CWM) Recovery Mode.

-- Choose "Install zip from SD card" and select the downloaded file.

-- Reboot your device. This should solve the battery drain issue.

Of course, there is a possibility this process could lead to a voiding of the device's warranty.

Samsung has not officially acknowledged or commented on this problem. It is most prominent in the international version of the device, and it does not affect all U.S. Galaxy S3 smartphones. The issue does not affect the LTE version at all, according to Software And Study.

Oh, also try this: Go in to settings then to the Wi-Fi area, then select advanced and make a small change by turning off connecting to Wi-Fi while you’re asleep. This setting should be changed to “never“. Your mileage may vary, but some that have tried this small change are seeing a notable improvement.

Also Google Play Music has used 9.1% of the battery lost and has 726.0 Wake Locks . It's Keep Awake is 31 minutes, CPU Usage (minus foreground) is 7 minutes and CPU Usage is 8 minutes. Not sure how to add screenshots from my phone to this post without uploading them to another website, but I have screenshots if someone can tell me how to add them. Thanks for the help!

It could be you have so many media files scanning them is causing a drain. There can be a file corruption problem causing excessive drain. It's not limited the S3, rather ICS. A corrupt file can cause the Mediaserver to go in to a loop scanning your sdcard.

You can create a “.nomedia” file in folders containing audio, video, or image files and this will prevent the Mediaserver from scanning the folders. Using this method you can determine if a corrupt file is causing issues, and isolate which folder the file is in. Unfortunately finding the paticular file will require removing all the files in that folder and adding them back one by one until the problem reappears after installing the corrupt file....

Also, you can go into the "Appsucker" portion of GSam, and select "view num times waking device" from the drop down menu to see what apps are waking the phone.

I thought my battery was doing well as I made it through 2 days without recharging...though admittedly I really didn't use it much. However, this morning I've lost 10% of the battery in 2 hours and the phone "reset itself" or something similar. Also, why is "Android System" using up a ton of battery now?




Thanks!!

Select "Android System" and it will give you more details, as well as what packages are included:

Yeah I checked that and didn't really see it in the top of the process lists. I had a process related to wifi constantly in the top.

Also your post is misleading. You only had your radio on for only 39 minutes out of 9 hours 40 minutes. I tested disconnecting mobile data and wifi; still had the radio statistic going in GSam. The only way I got it to stop like yours was airplane mode. In other words, airplane mode is definitely a way to get good battery life, but kind of defeats the purpose of having a phone when you can't use it as a phone.

Not in the least. If you read the post, you'd clearly understand the screenshot was illustrating the effect of leaving Wi-Fi and Bluetooth on the entire time (9hours 40 min) is so trivial as to be inconsequential in regards to overall battery time. Without it listing the incorrect radio stats, the rest of the information reported is actually more accurate.

My battery does pretty good. I have an extended battery, the Qcell 4200, but unless the stock battery goes bad, I will not be using it.

Isn't that pretty much with every phone? It's the reason I returned the Photon Q. Couldn't pop in a fresh battery after hours in a bad signal area sucked the phone dry.

Default Phone Battery..again!

So I'm more than delighted with my GS3 its a thing of wonder and as crazy as it sounds I can't remember life before I got. Anyhow I know alot of people have or have had issue with the battery but I think I've managed to find a state of zen with mine.

I had been noticing that if I left my fully charged phone by my bedside while sleeping I'd wake up and find the battery had fallen to between 65%-85% during the night. That seemed like a whole lot of battery to lose considering I wasn't using it and I'm sure many people would agree.

I also found that through the day at work I was losing at least half of my battery power and the only thing I was doing was texting because the 3G in my office isn't particularly good.

It was really getting on my nerves because I was finding this was happening alot and I didn't feel the battery was performing as well as it could. I read alot of threads on this forum and watched a few videos on YouTube and tried a whole combination of things.

So the thing I've found to work for my particular circumstance is to switch off WiFi, GPS, Mobile Data and Syncing during the night and also when I'm at work through the day. Last night my phone was at 100% when I went to bed and I woke up this morning at 5.40am with it at 98% which I was very pleased with.

I listened to some music on the way here and sent text messages to some people, I then turned off all the aforementioned things when I entered the office, turned them on to check emails and social media during lunch and at this current time (2.30pm) my battery is at 85%.

I didn't realise how much mobile data can drain the battery and I suppose that was very ignorant of me but hey I'm a newbie and I'm still learning.

I know its not always that simple but I thought I'd share my experience in the hope that it may help some of you save that very precious battery power. I'm hoping to keep the phone off charge to see how long I can get from it.

turning Wi-Fi and BT off does nothing for you, nor syncing really if you have it set up properly. mobile data is what is using your battery. since you are in a poor 3G area it will use up more than normal (the weaker the 3G signal, the more battery power your radios will consume).

I've found this to be true,a weak 3G signal is equivalent to pulling the plug on a sink drain.
Even streaming music over a solid data connection seems to have little battery drain, only when the signal is weak or disrupted constantly.
So, enjoy the features that make a smartphone smart & install a good battery monitoring app. Then, take a look @ it first thing in the morning & see if any installed apps have been keeping the phone from sleeping & draining your battery.

I myself use GSM BATTERY MONITOR, as it provides a lot of information w/a nice U/I to make deciphering the battery usage a breeze.

Yup I would agree with that I tend to use WiFi in the house a fair bit but I got the feeling the crappy 3G was a big factor in the drainage.

If you have wifi on, and are connected to a local network, does the phone still use mobile data? If so, for what? Thanks!

I don't know if that's true. With Wifi on the phone is constantly searching for available networks and I believe that takes power to do so, same goes for BT. It certainly doesn't hurt to have them off when you aren't using them.

So if you are connect to a network via wifi you are saying that it still searches for other wifi signals. That seems odd to me. I could understand if you had wifi on but weren't connected yet?

Its the latter, wifi + connected is best for power as mobile data is not being used but wifi without connection will keep scanning for networks.

With Wifi Connected:

Wifi 1 + Mobile Data 0

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

Wifi Disconnected:

wifi 1 + Mobile Data 1

That's not true. Both the BT and the Wi-Fi radios are passive; they only listen to the network and take almost no battery power (If Bluetooth was the only thing drawing power from your cell phone battery, in this passive mode your battery would go years on a single charge).

Since both are very short range (BT more so than Wi-Fi obviously) even when connections are established and they both send and receive signals, their power consumption is designed to be minimal.

Turn on the hotspot feature and the Wi-Fi - on top of sending and receiving packets - becomes a constant transmitter and will use significantly more power.

I am not so sure that the WiFi is passive. I also strongly believe that disconnected WiFi drain is not negligible. Sure its not quite as much as when its connected but it is significant, particularly when connected to mobile data.

I can see my WiFi (When disconnected) doing an active scan, every 5 seconds. Literally, if I go into WiFi settings - I will see the scanning icon and the word "Scanning" appear every 5 seconds. This is actually fairly typical of 802.11

Also, I have decompiled the frameworks and have identified the following boolean:

Code:
<bool name="config_wifi_background_scan_support">false</bool>
I am not sure if this refers specifically to passive activity, but a description for this bool is here:
Quote:
<!-- Boolean indicating whether the wifi chipset supports background scanning mechanism.
This mechanism allows the host to remain in suspend state and the dongle to actively
scan and wake the host when a configured SSID is detected by the dongle. This chipset
capability can provide power savings when wifi needs to be always kept on. -->
(citation from another source repository - https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/config.xml )

So my belief is that the chipset doesn't fully support passive scanning and is actively scanning every 5 seconds for networks to connect to.

With this in mind, I would also like to bring to the forefront, how Samsung estimates power usage

Code:
    
<item name="bluetooth.active">17</item>
<item name="bluetooth.on">0.3</item>
Well that definitely agrees what you say on BT as there is the entirety of it's power consumption values.

But for WiFi

Code:
   
<item name="wifi.on">0.3</item>
<item name="wifi.active">96</item>
<item name="wifi.scan">70</item>
So here we see 96 when connected, 0.3 when on but 70 when scanning (which my device does every 5 seconds). So yes I agree that it does not use as much power as when connected but I think this is significant none the less.


Where did the passive idea come from? Is it published in some technical specification document?

Yikes! I am almost intimidated by your post.

Very interesting stuff tho...

In response to your first question, many years of experience, schooling, and reading technical documents/diagrams, albeit not necessarily about cellphones or programming.

In answer to your second question, probably.

Without getting into a lengthy (which I have no problem doing as this is very interesting to me, but I must be somewhere in 30 min.) discussion, I am going to make an assumption or two.

WAPs (Wireless Access Points) transmits beacons several times per second. It is active in that it transmits beacons (or signals) announcing its existence. I am going to assume you and I agree on this.

In general, wireless clients are passive - I use that term in that they "listen" for those beacons transmitted by WAPs. As these beacons are transmitted several times per second, when a wireless client enters their range they seemingly appear "instantly". I would also assume we agree on this.

Now in my statements regarding battery usage on the GS3, I have taken for granted - perhaps erroneously, but I would have a hard time believing that - Wi-Fi radios in the GS3 and smartphones in general also work under this premise.

On the other side of things, I would use the term "active" to describe a scan which transmits or "probes", seeking out whatever (in the context of this discussion, that would be WAPs).

Now, stating that, I have taken a bit of liberty here in that I don't have a technical document that states this is how the radio in a GS3 (or in general, any smartphone) works. To me, it wasn't even a thought... Why would anyone design a radio in a device that needs to conserve as much power is possible that actually consumes power by actively probing for devices that they don't need to seek because they announce themselves?

Finally, and this is where it gets really interesting for me due to some things you stated in your post... using monitoring software to measure usage over significant periods of time, power consumption was no different in areas where I was connected to a WAP and areas where many existed, but none which I were connected to. The only difference in usage was when transmitting large amounts of data while connected to a WAP, usage increased over when I was not connected, or connected but not transmitting much data.

Anyway, have to run.. but I am curious about the coding you brought up... is everything shown on battery software based on the values as shown in your code examples? If so, given they are based on estimated values, doesn't it make the software rather inaccurate?

So I downloaded GSam and this is an example of the results it gave me...

Attachment 40826

Attachment 40827

As you can see, cell radio is what takes up my entire battery. But as you can see from the other picture, I have no trouble getting reception. So what is the cause? If it was a rogue app running in the background, wouldn't it show up under "apps" rather than radio? And even if it WAS a rogue app, can it seriously be responsible for that much?

EDIT: And if you're wondering why airplane mode is on, it's because I awoke in the middle of the night to find my battery low so I turned airplane mode on to ensure it didn't die in my sleep. So basically airplane mode was only on for an hour or so, so don't be mislead by the icon lol. Airplane wasn't on the whole night.
I have the exact same problem as you. 100% battery before sleep, 10% when I wake up. GPS, bluetooth, sync off, wifi, mobile data on.

I have to recharge the phone at least twice during the day, every day. This is annoying when I don't have a charger with me. Last week it died at 3pm and I had to use a payphone...something I haven't done for over 10 years! This is a huge problem and has almost rendered the phone useless.

Yeah I think we need to investigate further. I'm not saying either way is fact at this point. Just that I am not sure. The only thing I can say for definite is that my wifi settings page appears to be scanning every 5 secs. Scan 3, wait 5

Please don't be intimidated by my post. It's just information at this point

One further thing though, its possible a phone being the most portable that it works more actively to find a wap, given its usually in the pocket.

The values in power_profile.xml are estimates. These are used by the battery stats page. This is the file that caused the massive appearing cell standby "drain" so 1) yep its inaccurate as they are only estimates and don't take account if signal strength and 2) samsung already made one mistake in this file


Other battery apps break usage down much further than this file though so they can't be using it. They must be using draw to calculate.

My favourite was current widget. It logged mA for me at an interval of my choice (30 seconds) so I could historically see my draw. Unfortunately this doesn't support the s3 at this time.

I think next I shall look into the kernel source and see what I can see.

Yep its an interesting topic. Looking forward to getting to the bottom of it all.

On my desire, I definitely noticed a difference between wifi disconnected and wifi off. But as thats a software thing its extremely likely to differ between oems. I haven't tested on the s3 as tasker turns off wifi anyway

Hello

I have an external battery that i have been using with my old phone for about a year now, and decided to get a galaxy S3. I understand that the galaxy charger ouputs at 1000 mA but the max current output of the battery is 700mA. I have already tried using it to charge the phone but it took about twice as long as it does from the charger. Will using this battery with the S3 damage the phone, its battery life or have any negative side effects?

Thanks

Nope. It'll just be slow.

I'm a heavy user and work in some signal challeneged areas. I've even brought an iphone 4s in and showed me burning through its battery in under fiver hours just to shut up the fanboys at work. I'm more of a fan of spare batteries. I keep one charged in the car and one charged at home. Those little universal chargers that charge via microUSB are nice. And you're always going back to 100% after a swap instead of dealing with charging and being tethered.

Granted, there might be internal things going on via bad programming, rogue apps or what not, but also using an Epic (on Sprint) I do notice better battery life with slightly stronger signals in areas where I had less, or it hands off to roaming more efficiently. Still wouldn't mind seeing larger quality stock fitting batteries. It's a shame the third party ones never live up to their size claims and if they can make slightly physically larger batteries that fit with the stock back, why couldn't sammy stuff a larger quality stock battery in there? Everybody wants us to do more on our phones and everybody wants us to stream more and go to the cloud. Well this shit requires juice and nobody wants to do the one thing in light of more efficient processing, screens and other tech; and that's give us the biggest f*cking battery they can possibly squeeze in, even if it's at a slight thickness or size compromise. Sammy at least kinda gets it over Moto and HTC with their embedded silliness. Though Sammy really screwed the pooch with the Mini 3 IMHO.

Look through this thread and read the responses to blenkows posts. Try them and see what the results are. Unfortunately, he hasn't responded since the last suggestion... perhaps you can continue instead and follow it through?

Hero, Moment, Evo, Epic, Photon, Photon Q, S3. All suck in signal challenged areas and drain quickly, no less no more than the S3. All on Sprint mind you.

You could try disabling LTE, however this will lock you into 3g/4g HSPA+ and would not fall back to EDGE if you left a 3G area, but this would be done more to diagnose the issue rather than a permanent solution:

[How to] disable LTE on AT&T S3 (you can disable HSPA+ too) - Android Forums at AndroidCentral.com

You could also try leaving Airplane Mode OFF, and just turning the data off and see how that changes.

There is a fix over at XDA for the standby issue (it changes a file value from 34 to 3.4), but requires a rooted device (Don't have the original link atm but have the instructions saved in notes):

On the XDA Developers forums, boasting the largest community of application developers and smartphone hackers, some users posted that the battery problem stems from the Galaxy S3's standby feature. They said the file on the smartphone that contains the drain value was wrongly set when the device shipped. This file, known as the framework-res.apk, was set at 34mA when it should have been set at 3.4mA.

For an owner of the Galaxy S3, this means the phone may incorrectly display a 50 percent to 70 percent battery drain, as Auto-O-Mobile has pointed out.

Users experiencing this problem can fix it by changing the power_profile.xml file located in the framework-res package. To do this, complete the following steps:

-- Download the updated file (510kb) from MediaFire. cell_stand by_Fix.zip

-- Save the file on your microSD card or internal storage.

-- Reboot your Samsung Galaxy S3 into ClockWork Mod (CWM) Recovery Mode.

-- Choose "Install zip from SD card" and select the downloaded file.

-- Reboot your device. This should solve the battery drain issue.

Of course, there is a possibility this process could lead to a voiding of the device's warranty.

Samsung has not officially acknowledged or commented on this problem. It is most prominent in the international version of the device, and it does not affect all U.S. Galaxy S3 smartphones. The issue does not affect the LTE version at all, according to Software And Study.
Even if it was just reporting it wrong, that doesn't change the fact that my battery was drained. When I sorted by "total time held awake", it was only like 2 minutes. Something MUST be causing it to stay awake that isn't getting reported or something...

And it was strange. I took out my battery, put it back in, and the problem appeared to go away for a few days. This is why I stopped posting lol. Well.... it's back as of last night.

And I don't really wanna mess with the software and all that. I'd rather just know WHY this is happening is all.

I just bought Roam Control, and in two places where my battery would just drain trying to maintain the Sprint signal, I now force roam on Verizon and maintain around 3 bars with much less battery drain. Next Tuesday should be a long day at the one place so I'll see how that works.

They really should address situations like that. There has to be a point when the phone has to stop struggling to maintain the home network connection and force into roaming. Let it go check every 10 minutes or so for a solid home signal, and if it's not there, keep it roaming.

Thanks for all the great info - very good thread.

I could use a little help with my phone. Battery life is starting to really go downhill. I am generally a light user. I don't have too many apps and try to turn off syncing on most of them aside from gmail. I got a full charge before bed last night and woke up at about 68%. Not awful, but definitely not good. Any help would be greatly appreciated.

I could use a little help with my phone. Battery life is starting to really go downhill. I am generally a light user.

Any help would be greatly appreciated.
Not a solution but a curious question. Why would you not charge the phone overnight so you wake up with a fully charged phone to start the day? Seems like a basic thing to do.

Try turning mobile data off before you go to bed and see how that affects it. One of the things I think we overlook is the reporting issue with the radios. Sure, it's not reported correctly, but that doesn't mean we can rule the radio out all together.

Unless I'm missing something everything else looks pretty normal.

It should turn everything off. If you received text messages then airplane mode was not on.

I do generally charge my phone at night, but I was noticing my phone performance was down during the day so I wanted to see how would perform overnight with no use.

I will give the mobile data a try tonight. Would you agree that that is a bit of a heavy drain overnight with no obvious battery hogs?
