Rogers Galaxy S3 battery drains ultrafast

Hi folks,
I have had my rogers S3 for several days now. while i love it very much but one issue frustrates me. I get only about 6-7 hours for one charge on a maybe a little bit more than moderate use.
I read somewhere there was an error in one of the system config files but that article was talking about the international version. do any of you experience the same?
My GS3 battery life is going against all the reviews. help.

I had the same problem, I did a factory reset and it seems to be considerably better now.
not sure why the phone kept going into deep discharge, but it hasn't done it since and it's been a week or so now.. is your phone also warm near the USB connector?
The error in the config file was just in regards to the reporting of usage.. Cell Standby usage was being over-reported.. I am not seeing that as being the case on my Rogers SGS3..
One thing I did do is nuke all the rogers installed apps.. I got sick of the VVM+ whining constantly about not being able to work over WiFi.. I just used Titanium Backup to freeze all of the rogers apps.. (rather than uninstalling them).. battery life is quite good actually.. very surprised.

thank you for the info. how is a factory reset done? does that mean i would lose everything i downloaded already? i will give the Titanium Backup a try to get rid of the rogers apps too to see if it helps. yeah, the phone gets pretty warm after a short while.

Are you on LTE, My battery gets about the same with LTE always on since it does consume a lot of power

Well.. this may not be a fix but it really worked forr me. Battery time was at least trippeled.
I drained my battery until the phone shut down, then I connected the charger WITHOUT turning on the phone (allright I KNOW it sounds stupid). Noticed the time to charge it fully increased from 1.5-2 hours to 4-5 hours.
I had to charge the phone during the day before, now it last for 2 days at least.
The cell standby is still wrong but that is just a indication fault, this was a real problem for me.

it's the rogers apps!!!
FYI - disable the rogers apps (all of them) and your battery life will DRASTICALLY increase. I've tested this with them enabled (battery life sucked), and disabled (battery lasted for like 1.5+ days).
Oh and let rogers know their apps suck like I did. The more people that report it the more chance they might actually fix them. A fun way is to do it to their twitter account @rogershelps
If you decide to keep them disabled, be sure to call Rogers and tell them to remove any of the features those apps use...thus reducing you monthly bill.

Forgive my ignorance, I have a VZW GS3. What are Rogers apps? What app names should I look for to see if they're on my phone? Thanks to VZW I cant unlock and root my phone this may not matter.

why don't you return it for a new one?

Rogers is one of the provider here in Canada...similar to AT&T. They each have their own bloatware that they install in their phones.

With root you can either delete them or use titanium backup to freeze them (stop them from running or updating).
I did this (freeze the Rogers apps and most of the samsung ones) and get all day battery life (6am to midnight) with between 4 & 5 hours of screen time.

I've found that battery life is related to cell coverage. If I have 3-5 bars and I'm not using the phone I could lose about a percent of battery per hour and my phone will run at a 40-45 when I do use it. If I only have 1 or 2 bats and it keeps switching between 3g and 4G I could easily lose 6-10 percent an hour and my phone will run at 50 or so degrees celcius. A restart seems to help the phone get a better lock. All this temps were cpu temps.

I just did a wipe/reset and found that this worked for me. I couldn't squeeze out a day with it and now go to bed with 30-40 percent left.

Battery life
My battery life on a debloated stock build was average. I was getting about 16-18hrs on moderate use. I've recently tried CPU Editor battery saver profile and so far its going great. I'll post back on the results after I go through a few charging/discharging cycles.
The forum page for the CPU Editor is here: http://forum.xda-developers.com/showthread.php?t=1798765
[MOD/SCRIPT]CPU Editor SGS3 Edition - Secret to Die Hard Battery

I'm with rogers and my battery is pretty awful too. Not quite as bad as yours, but still not as good as I'd hope with LTE off.

What kind of usage do you have though ? For example I work with a guy who has the same model and was complaining about battery. I checked his stats and was at 35 percent battery with 4 hours display time. If you're getting 5 to 6 hours screen on time that's enough to kill battery. If its in standby for 6 to 7 hours and battery is dying then something is wrong
Sent from my SGH-I747M using xda app-developers app

I've had very similar issues. Tried several ROMs and had charging problems and finally ended up on cm10 and it took about 3.5 hours to charge from 30% to 85%. Then dropped to 80% after only thirty minutes off the charger. Not sure exactly what to do to fix the issue.

SOLVED: ICS Upgrade Myth Dispelled - Factory Reset Does Not Fix Battery Drain

EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Did you backup and restore your app data as well?

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.

It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.
You might also want to get a battery monitoring program and see what is using the battery up.

its not a ics glitch its your phone lol.. ive never had this issue.. plus with the source kernels coming out and with roms/tweaks already out youcan increase battery life yourself.. because your battey cant keep a charge you bash ics? go back to gingerbread then lol. i can use my phone for two hours and leave it off charger over night and still have at least 50% charge

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.

Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.

This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.

Confirmed, factory reset battery drain exists.

OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

I'm a super n00b, if you or someone could link me to the best ICS ROM the cool kids are using I can figure out how to install it.

However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

Battery Drain

Is there an app or way that conserves the battery power. The phone is still completely stock but it received a firmware update through Tmobile and ever since then the battery gets drained by 4 pm (after all apps are x-ed out and phone is just in standby) the batter drops to around 30 percent... what can I do? I don't think it needs a new battery since its only a few months old... suggestions?

I dont know how much you use your phone and weather or not you watch movies or download files with Wi-Fi alot but it could seriously drain your battery if you leave things like Wi-Fi, Bluetooth, NFC, Brightness Up, or use live wallpapers.
If not, I would recommend checking your battery against someone elses because I've had a phone before that had a bad battery that could explode and caused me to have battery issues. Make sure your battery isnt swollen at all and if it is make sure you take it out and dont put it back in and go to a Battery+ store nearby and I'm sure they got one for your phone (they come with warranty).

Well my wife and I have the same phone and it does it to both. I don't have signal in my job since they have a Verizon antenna and it blocks our t mobile signal so I don't use it during the day which means the phone is just on stand by for the first eight hours. I make sure I turn off wifi, blue tooth, GPS etc and close all apps....but by the time I get out of work it's at 30-40% power.... both phones were bought this April so was hoping it wasn't/isn't a hardware issue and have to replace the batteries....

This is where the world of rooting and tweaking your android becomes extremely attractive.
There are ROMs that last 1 day + ( that's 24h+ hours of battery)
Only need two things....
1. Patience - to sit, read and closely follow instructions
2. Guts - to take a dive and risk ruining your phone. (Which doesn't happen if you have number 1)

1. juice defender is a start.
The rest all needs rooting really.
2. Build.prop tweaks
3. UV with a custom kernel
4. Lowest screen brightness (doesn't require root)
5. Restrict yourself to 2G networks either using AOKP settings or a build.prop tweak
There are others but this is how I achieve great battery times mostly.

Why not try and find out what is using your battery up first? Try GSAM from the play store, its free for one, easy to use, it will show you what is draining your battery, there are a few paid ones as well, but try the free first , HERE is the direct link to GSAM.
or QR code, just scan it with phone.

That is a very weird situation and try a app that shows the apps using battery. Even check the stock android battery section in settings and see whats getting used. Your brightness should be first since it can really eat your battery if its turned up. I dont think its defective since both your phones are having the same problem but both my parents have the 4.0.4 firmware installed on their T989's without a problem and get decent battery power. I however am using a custom rom with kernel. Did you use the same battery for each phone? or each phone has the same problem with their own devices and their own batteries when getting updated to 4.0.4? If you used your battery on her's I'm assuming the problem may be the battery and you just got unlucky with a defective one.
P.S. I'm assuming 4.0.4 because thats the latest update to ICS for the T989 on T-Mobile.

The battery manager that comes with the phone identifies the display, but I've set it to lowest setting and have a dark background. And yeah both phones have their respective batteries which makes me think it's a software issue.. We just upgraded to the 2.3.6 ( I guess t-mobile is a but behind lol). But I going to try the juice defender tomorrow... It's just while I root the phone and get a custom ROM... (doing my homework before doing anything since it'll be first time)
Sent from my SGH-T989

Those apps wont really help, it basically does what you can do manually, turning off settings or putting them at low usage. Rooting is the way to go, its rather simple, once you do it, you will have wished you done it sooner. Trust me, I was in the same boat, I had just got my phone last december, the wife and I were in Vegas and my battery was horrible, I was taking lots of pictures and video, but my battery was dying. I had no way to charge it til we got back to the hotel, next day was same thing, horrible battery, this was all before ICS even was around for this device. When I got back home, I rooted my phone, to date, I have gotten a best 44 hours out of the phone. I ROM hop so I try out the variety, there is how to's and videos here and youtube, you will kick youself on how easy it truly is to root and flash. GSAM will show you in more detail what is using your battery the most, good luck with whatever you choose to do. There are many people here who can help you along the way, thats what this site is for.

Juice Defender will help a ton with you're screen being off for extended periods of time. Normally without it, I lose 30% at work without touching it. Today, I have lost 6%. The margin won't always be like that but it's a sizeable difference. Also, I have an app monitor application you can use to track rogue apps. There is also this app called Autostarts where you can disable an app from opening and it's really useful for apps that you don't need running in the background. Turning off auto sync will help as well IF you are okay with not getting every email in 5 minutes.

Verizon Galaxy Nexus battery fix!

Hi all, I found an awesome way to actually get solid battery life on my galaxy nexus last night so I thought I'd share with everyone:
So theres about a bazillion threads about people only getting 10-14 hrs of battery life on the Galaxy Nexus, and it looks like alot of them have to do with "Phone Idle" just draining the battery. Lately I'd pretty much given up and just figured that 14 hrs with normal use was about all I was gonna get.
Fast forward to last night, I was using Titanium Backup to go through and delete some of the Verizon crapware that comes on the stock ROM. I deleted "My Verizon Mobile" and "VZ Backup Assistant" and then left it fully charged over night to see what would happen. Woke up this morning and my battery was at 90% after 8.5hrs! Been using it lightly today and currently I'm at 58% battery after 17hrs.
So obviously one of these 2 applications has been running in the background and keeping my phone from going into deep sleep. Super glad to finally have this figured out!
BTW I'm running rooted stock 4.1.1. Also attached a few screenshots of the battery stats:

good find man. most roms already leave those apps out so i think you just got lucky because i still see pretty terrible battery. i suggest trying out a custom rom and kernel and youll get even better battery life. btw try to shoot for a high screen on time because thats when battery life really counts.

Phone Idle and Cell Standby higher than Screen... Of course you'll be getting good battery life if you never use the phone. Screen on time is the only good measure of battery life.

Probably a majority of users here don't have those apps because they have installed custom firmware. But AOSP has the same problem.. First thing I do after flashing gapps is "disable" all the Play apps (books, magazines, videos, movies, currents, etc).

Yup, this is why we Root & ROM. There are MANY Verizon apps/services that run whether you want them or not, and that is completely bogus. It's no wonder that we love phones that can be unlocked.

I agree that screen on time is the best measure of battery life. The best I ever have gotten is three hours of screen on time. That was done using WiFi all day and screen at lowest brightness setting.

[Q] Android System is draining my battery!!

I just got the Note 2 in October of this year. I have always been amazed at the battery life. With regular use, texting, emails, internet and phone calls (nothing crazy), I easily could go 2 days on a charge. Now for the past few days, I am already at 71% and it's just 11am. I can't figure out what is going on. my battery meter shows the Screen as first then Android System next at 22%....Easily dropping 5-10% per hour. Help!!

It is running on Android 4.1.2. All of these things I am reading about rooting and stuff are foreign to me. I just want my battery life back. Any help would be appreciated.

Have you adjusted anything with your brightness? You may have accidentally turned off auto adjustment if you were using it previously. If that's not it I'd suggest a hard reset. If that cures it you can most likely chalk it up to a recently downloaded app.

When you get a chance run the battery down to 1% then power off and let charge for at least 20 min after light turns green. ..you'll probably see immediate improvement

i've had to move google play services as a user app with titanium and then greenify it. all my devices started getting big time standby drain last month from google play services.
i do have the donation version of greenify, but i didn't feel like installing xposed to use it.

OMGosh...I updated to 4.3 and did a factory reset as well and it is not helping! What does it mean to "root" your phone? Will rooting the Note 2 nullify my Samsung warranty? Someone please help....

yes rooting will void your warranty but there are methods you can do to unroot it and have it go back to stock rom. I, as well as most of the people in this community get better battery if you root your rom and install a custom kernel, you will get better battery life.
one app that I found that I use daily is 2x battery pro. it's not free though.. there is a setting on the app that lets you turn off any background data while the phone is idle; you will still get calls and texts though. this will give you longer battery life. when you turn your phone on data will come back on. I get around one day and a few hours from the charge. check it out man. might help you..
