You do relize that you have Steam, A virus protector, and all those other Apps installed that eat away at your battery. Also have you taken into effect that coverage signal can affect your battery life to.

el29 has significantly increased battery life for me....

Your Android OS is exactly where is should be based on your display percent. If you actually turn your phone on in that time Android OS will start to drop and the display percent will start to move up...

It may be that your phone is not sleeping with the display off in some circumstances.
Probably all those background apps waking it up to check internet for updates.
You need to post your actual display on time also.

My battery life has suddenly dropped too since EL29. I updated and everything was great for a few days. One day I woke up and my battery was draining at about 10% an hour with no use. I've tried rebooting and it seemed to help a little but I'm still dropping at about 6% an hour where before update it was 3% an hour. No idea what's causing it and it was really odd how it came out of nowhere.

I asked somewhere in another thread for someone who had the skills to see if there was any major differences between EL26 and EL29 because I actually prefer EL26 but I figure they made 29 official for a reason

Stop using a nonsense app that does no good to your phone. Who in the world need anti-virus app for android. An't no hacker would spend time to come up with a virus that will steal your info. Some apps claim to do this and that but is just all BS. All you need is an app killer and that's it. If you have an app that is continue running ( other than the one require ) than of course is gonna drain the hell out of your battery and it will get hot.

I have a Seidio 3200 battery which was giving me almost 2 days of moderate use . Immediately, and I mean immediately, after the OTA my battery drain almost doubled according to my stats... I read XDA on the subject, and did a HARD factory reset witth DATA wipe.....no help. Thought maybe the battery was failing..so I ordered a 3800 Trexcell from EBAY. Then read the problem might be from a looping background app or a stuck radio....pulled the battery...waited 5 minutes...put te battery back and now I'm back to normal (if not better) battery drain....It might be that some of us who had OTA got a screwed-up install which affected background apps or radios, while some of us had a normal install...in either case... I'm happy to get my battery use back !

My Android OS usage is through the roof now, aka Android OS bug. I installed watchdog and it's the "suspend" and "events/0" processes running at 65-85% when the phone is supposed to be sleeping.
I have had this phone for 5 months without the Android OS bug. I installed EL29 on Feb 2nd. Everything was fantastic until Feb 5th then I suddenly noticed my battery draining faster than normal.
After spending about 3 hours reading up on the Android OS bug this morning I've come to the conclusion there is no remedy for this bug. Sadly Samsung has not fixed it and it's even happening to people with the Galaxy Nexus running ICS.

Same here. I am getting up to 24 hours with stock battery (syncing exchange as push, facebook and gmail), on strongsteve odexed blue rom.

It seemed like battery got better since the updates began (EK02, EL13) and then the battery drain got worse than ever with EL29. For comparison's sake I live in Chicago and work downtown during the day in a not so good cellphone environment for most of the day.
I reverted back to EL13 radio and Rogue's EL13 Repack Kernel, topped off with Calkulin's 2.8.1 ROM. Battery life seems to have returned back to normal, but Calk's ROM makes it that much better.
I plan on giving the battery removal trick a shot too tonight. Someone else on Rogue's or Calk's thread said that removing the battery after a full charge for 5 mins, then recharging again, made his battery back to normal if not better.
Here we go!!! My phone is almost complete!!!

It's not a bug...

Is very high awake time normal?

My Galaxy Nexus is unrooted, locked bootloader running stock 4.1.1
My battery life seems to have gotten pretty bad recently with the battery running out within 9 hours without the phone being used. The screen on time would be something like 20 minutes and the device awake time would be 8 hours! Surely that is not normal and is draining my battery?
Any idea to what it could be? Could it be Google Now?

Look for BetterBatteryStats to get a handle on whats using up your battery.

what above post said.
Google Now should not drain that much of a battery if its not in use.
Having your sync all on will drain battery. Apps Facebook/twitter/g+ all those kill battery. Data Connection kills battery. Google Maps..pretty much any app with data will drain your battery so disable your data connection if you dont need it.

Could also be some app not updated to run properly on JB.

battery problems

My girlfriend has a GS3 love the phone but it has a serious battery drain. It doesn't matter if its a stock or custom rom. It is running stock 4.3 right now and the battery has gone from 100 to 83 in 3 hours. with 30 min screen time. I thought it was the battery so i got another Samsung battery and its not ant better. I tried to search but it seem the search funtion is not working because it gives me nothing no matter what I search for. Any sugestions would be great.

Sometimes when it's charging it says 100%, and then when I take the charger off it suddenly shows up 37%? WTF?

try a different charger or port
2nd updating from 4.3 from 4.1.2 has a big change to the phone how it works etc and by that the phone takes time to adjust to 4.3 thus getting bad battery drains, a week or two or a month and the battery will be as good as ever

Get battery saver or juice defender this are two apps I have used to monitor my battery usage and they recommend to charge the phone to 100% and that will change as to how fast your battery dies
Letting the phone die and charging results to bad battery life while recharging phone at a timely manner increases battery life
Also note that GPS/WiFi/data/screen drains battery like crazy so fix those and you will notice a big difference

lollipop battery

It seems that with the new update I am getting less battery life then when kit Kat I have everything the same expect no root and I would usually get around 5 1/2 battery life on kit Kat with root but now I'm nearly getting 4? And I already factory reset it and it's still the same any help ?

Im having similar results, with 3 hrs screen time being my average. Fresh install, wiped clean, etc etc.

Mine is about the same. I have it set to power saving mode. Just not affecting background data. Getting a full day with it without having to plug it in till about 11pm, my day off charger starting at about 5:30am. It might be your settings and if you're a power user. I use mine all through the day, from streaming audio to social networking and talking and texting or surfing the web. Even watching videos!

My battery has taken a hit as well. I'm seeing about 20-30% less energy from what I used to get.

before the update I unplugat 7:30 I got to high school so I stream netflix I use YouTube occasionly read books at half Brightness with no auto sync nfc Bluetooth off WiFi off till I get home and when I'm not using my data I turn it off (even though I have unlimited ) then when I get home connect to WiFi and keep streaming YouTube and text social media and never worried till about 10 or 11 with around 5 hohrs and 40 or 45 min at 10 % but now I bear get 4 ost

You people do know that just like when you flash a ROM you have to train the update or ROM to the battery. To do this you have to completely drain and charge the battery a few times. I get better battery time with Lolipop then I did with KK. But I also trained the battery and system.

Yeah I was thinking that also but idk if that was the answer or there was something going on because when I first got this phone I couldn't get more then 4 hours ost but now I got more, until the update

You all have to also remember that if you use a KK rom that they were heavily tweaked by the rom maker most times for battery life/performance boosts.

These both make a lot of sense when it comes to battery life. I concur with them both. From a stock standpoint and the custom tweaked.

With stock NK2 I was getting almost 30 hours wothout charge and about 4 hours screen on.... now with OB7 i am lucky to get 10 hours with 1.5 hours screen on. Seriously thinking about going back to NK2. yes I did a full system wipe 3 times to be safe and still having said issue with battery

Have you fully discharged your battery to the point that the phone shuts off and then recharged with the phone off at least twice? If not you should give it a try. This is supposed to be standard procedure any time a ROM is changed or updated. The ROM has to learn the charge and discharge characteristics of the battery and the only way to do this is to have it run a couple of full cycles.

Accidentally gave thumbs up. Anyway, not sure if that's true. I've installed many roms across multiple phones (like most of you have) and I've drained and charged batteries after installing roms and sometimes I haven't. Either way I haven't noticed better battery life. It's usually the same.

This only gives you very small gains if any, also this matters more only if you don't ever let your phone die completely/have a non-stock battery.

Thats usually whats going to happen, small gain/loss. Nothing amazing unless you have an extended battery the device needs to learn to use.

[Q] Performance/battery life on stock 6.0.1? Currently on 4.4.2 [Wifi]

Hello
I am currently on stock rooted rom on 4.4.2. I never bothered updating since it served my purposes of watching movies.
I need to gift my nexus to someone I know, so wanted to update and unroot before giving. Would anyone please tell me how the performance and battery life is on 6.0.1 stock (will be used unrooted most likely)? I have the Wifi 2013 nexus 7
I understand it may be too obvious of an answer butI searched the thread but could not find an answer. Been away from xda for a long time. Good to be back!

I have owned my Nexus 7 since Christmas it came with 6.0.1 Marshmallow installed and I am very happy with the performance and battery life. I don't know how it compares with an n7 running 4.4.2 but I have had plenty of android devices in the past 5 years all rooted etc so know good from bad. Just be aware that some n7 owners have had issues with firmware updates leading to bricked tablets. I would say go for it, do a full wipe first though and maybe use the excellent Nexus Root Toolkit by Wugfresh. Enjoy.

Pretty Great!
I am not running stock. I am on Commotio by TeamVanir and I get 1-2% discharge on standby during 12-16hours and when I am using it and watching youtube over wifi or just general browsing on reddit and google plus or chrome I get around 5-7hrs of SOT. My tablet is around 2 years old now and I used to charge once every 3 days so its battery is also not what it used to be when it was new.

Stock rooted, I use about 8%/hour (reading, internet connected, dim screen), about 10%/hour browsing the web, dim screen). I routinely let it sit on a Qi charger when not it use, so can't comment on the standby time. Subjectively, much better than I saw on KK.

I just updated mine recently to Marshmallow from Kit Kat as well. I had an issue on 6.0.1 with standby battery drain being about %10 overnight, even though it appeared to enter doze correctly. I couldn't identify any wakelocks that accounts for this drain.
I switched to 6.0.0 and it's much better now, completely same settings and apps. Overnight, it's probably a 1.5% loss, if that. Overall, battery performance is improved. But for me, 6.0.1 didn't work out. Not quite sure why.

When you flash a new build you have to wait for a couple of charge recharge cycles until it correctly displays the battery. On a different ROM normally i lose 1% per hour on standby but after just updating and for the first few cycles even in dozd I loose more than 10% and sometimes even 50% during the night but it settles down after a charge cycle.

Good information, thanks! I had already given it a couple weeks and few discharges, but I'd be willing to try again and hope it will work itself out.

But is the performance better or worse? And is rooting / unlocking still no problem?
