ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.

Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Rooting takes 5 seconds. Follow the sticky. Use odin.

Thanks, although a lot of howtos seem to be for GB since ICS only landed 9 days ago. Also there's a lot of conflicting information, so I prefer this one:

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.

I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Get a gnex extended....maybe a bad battery

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Question regarding battery life after rooting.

So, I rooted my S3 with the stock ROM. For some reason it seems like the battery life has diminished. Anyone else experiencing this? Any recommendations? Advice? THANKS!

Did you get any suspicious root apps after rooting?
Even a lot of legitimate root apps can still harm your battery life.

Do you mean ones that I downloaded? I don't believe so, except root checker/ti back up. Trying to be stock, but need WiFi tether...... Thanks!

I'm getting this as well. Today my battery only lasted 4-5 hours with very light and I mean light use.

Rooted and custom rom, getting around 13 hours with mild to heavy use, 4 hours screen on time.
Sent from Pluto.

Root will have no negative impact on the battery. It has to be an app or something. All it is is access to the root level or system partition.

4 or 5 hours is pretty good for heavy usage. OP go to the battery options in settings and check the cell standby. My area has horrible Sprint coverage and I found that in the 10ish hours of time the phone was on, I had about 1 1/2 hours of no signal. That's definitely detrimental to battery life.

Just wanted to update this thread, I installed Juice Defender Plus and my battery life has been EXTREMELY better.

For those that are getting bad battery life after flashing a ROM the reason for that is you need to let it settle in. After 2 or 3 charging cycles it should be back to normal if not better.

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)

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.

Help Battery Life

I have been stressing myself out about this for over a week, trying different things, buying new batteries trying new chargers, changing roms.
Turning so many things off basically making my phone into a dumbphone to try to figure out why my battery life is so bad. Could it be I just have a bad phone and need a new one??
I had a Galaxy S3 gave it to my GF, never turned any sync services off and I am able to get 20+ hours with that phone, this phone is HORRIBLE.
I was stock getting about 5 hours before dead battery (phone would get real warm- battery stats showing 33C+).
So I rooted and took it back to an LJC rom (4.1.1). Tried different modems, kernals, files tweaks with root explorer.
I bought BBS, a battery calibrator from the market and still cant see any problems that would do this?

last picture......
Should I just take it into Sprint and get a replacement???

But it really does sound like you got a lemon here, I'd get a replacement from Sprint. I don't think I could kill my battery in under 10 hours unless I was playing a game non-stop. My phone is completely stock.

Those partial wakelocks are PURELY from Google Now and the wifi/network based location. Either turn off Google Now, or turn off network-based-locating and those partial wakelocks will disappear....I'd also wager you have Sprint Connection Optimizer still running causing your phone to hangup trying to find a network conenction.

My battery took a good hite when I updated to 4.1.2 used to get 20+ hrs with 7+ screen time now I get about 14-15 with 4-5 hrs screen time

Based on your first pictures, your status bar, and the amount of awake time your phone is showing I'm guessing a couple of things. Do you have a phone signal where you spend most of your day? If my awake bar was solid like yours I wouldn't have a battery after 7 hours either. I would backup everything and do a full wipe / clean install and run the phone a day or so.

Meh. On this device I always aim for getting 10%/ battery usage per hour of screen-on-time on TouchWiz ROMs, and a fraction of a percent per hour in screen-off....something is burning battery here, and it is probably a system setting.

The thing is, I have a Galaxy S3... The Note II is setup no different then that, settings or otherwise. I am trying all of these suggestions, but why did I not have to turn any of these off on my S3?? Same service area obviously. I took the Galaxy S3 off the charger last night at 100%. Put a new battery in the Note II so it was at 100%. Let them both sit on the counter for 1 hour. S3 had 98%, Note II was at 87%... No calls no texting, no screen time. It is so fustrating! I have had my fair share of battery tweaking with previous phones (HTC EVO, HTC hero). It seems something isn't right. I had problems with stock rom, that is why I rooted so quick, to try a different ROM.
If the wipe does not work I will try to get Sprint to get me a replacement, was hoping the get this figured out before I fly to Florida for a week. Good thing I have extra batteries.

[Q] Battery Life Issues

I received my S6 Edge on Wednesday and rooted it the same day via Ping Pong. I'm on G925TUVU1AOCG. Is that even the latest version? Anyways, battery life is literally ****. I can't get more than 2 hours of Screen on Time. Even my Galaxy Nexus from 2012 gets at least 2+ hours.
Is this because I'm not on the latest version, rooted, or something else people have experience with?

I've had horrible battery life since I've rooted using ping pong this week. I don't think my phone is going into deep sleep but haven't checked it yet. It drains fast when not being used.

Yea so I flashed the stock ROM with Odin and unrooted. I didn't wipe data however. But battery life still sucks. For anyone that cares .

I read a trick about disabling google now and it seemed to help drastically.

Yea so I flashed the stock ROM with Odin and unrooted. I didn't wipe data however. But battery life still sucks. For anyone that cares .

I went through this issue with my first S6. Re-root and download better battery stats - or CPU Spy. See if your phone is going into deep sleep. Mine was constantly kept awake by lli_pm_wlock. I couldn't find ANY information about it on the internet - but it was keeping the cores active and burning through battery like crazy. It would occasionally enter deep sleep, but only for a few minutes at a time.
I ended up returning the phone and getting my new S6 Edge. I tried everything - factory resets, flashing stock firmware via Odin, basically everything possible without tripping KNOX with a custom kernel.

My battery life has been awful. Specially after rooting with Ping Pong and specifically last night. 100% at 10PM, and at 11AM with 58 minutes of on screen time, the battery was at 13%. That is just horrible. Worst battery life I have ever gotten out of the phone.
Pains me to say it, but if the battery doesn't improve by unrooting it, and waiting for a future update to 5.1, I'll most likely change to a LG G4.

If you have it rooted install Better Battery Stats and figure out the problem. If it's a wakelock, the problem is it's just not going to sleep. Something is keeping the CPU active even when the screen is off and nothing is going on. It's a common problem on the rooted phones - but usually PingPong Root doesn't have the issue. Enter recovery (turn off - then power, vol up, home at the same time) and clear the cache. Reboot and run BBS for a while.

I received my S6 Edge on Wednesday and rooted it the same day via Ping Pong. I'm on G925TUVU1AOCG. Is that even the latest version? Anyways, battery life is literally ****. I can't get more than 2 hours of Screen on Time. Even my Galaxy Nexus from 2012 gets at least 2+ hours.
Is this because I'm not on the latest version, rooted, or something else people have experience with?

I also have the same experience but instead I just keep my phone on Ultra Saving mode

It's been really difficult for me to try to drain my phone to see my average screen on time.
But is this normal? I'm not sure what is a decent Deep Sleep percentage.
Btw: This is after I unrooted without factory reset.

Yea we're having very similar issues. I would try the G4, but the Edge is too beautiful!! This is the first time I've gotten a phone so soon after release, so I'm probably gonna stick it out for a month or 2 and wait for bug fixes.

So I purposely didn't charge it last night, and you can tell it has really really bad standby time.

Try disabling WiFi or set it to keep it on only when plugged in.

That is not normal. Backup your data and flash stock firmware with SmartSwitch then restore what you want. See if that makes your battery last any longer.

I had horrible battery life when I got it out of box. It wouldn't last more than 5 hrs with very little use. After I flashed stock firmware with SmartSwitch, Battery+ RAM Usage issue got solved. Now I get whole day with single charge. I take my phone out from charger by 7 AM and by the time 10 PM in night, Phone would still have 35-40% battery left. I get many emails [50+], 2hrs of GPS+Music streaming + random facebook & Instagram and even after this, I get good battery life. So I would 1000% recommend that you do a flash stock firmware with SmartSwitch.

I tried using SmartSwitch and unfortunately, battery life was only a tiny bit better. However, I started getting a bunch of force closes, and the phone became laggier than before. I would try it again, but it's so much work resetting up my phone! ...especially without root.
So I ordered the G4. Hopefully I'll be getting the Note 5 in a few months .
