Develop Bugs

(TIP)Possible battery drain solution for LTE devices.

Like many here I've been having battery drain issues since the day I purchased the Galaxy Nexus. I also purchased the extended battery since day one. I've been reading through every single forum on how to reduce the battery drain and none seems to have worked for me. I've tried switching to wifi, 3g only, no email push, no google+, etc and my phone at 100% battery would lose almost 30% within 2 hours idling. Then I was looking at the settings and I came across the Developer Options/Background process limit and limited my background process from Standard to At most limit to 1 process and my battery has improved tremendously. Prior to making the change the Android OS was using 80+ % on idle (Wifi or 3g didn't make a difference), now it's uses around 20 or less. On idle I'm seeing around 4% or less an hour vs 15% battery drain.
Please remember this may or may not solve YOUR battery drain, but it has definitely helped mine and I just wanted to share with the community on what else you can try.

I've had pretty good results with my battery. I think some of ya'll are either just playing around with it too much or have some energy-sucking apps out there.

Or that you don't have a connection to the data network.
Just say'n. (I do the same thing at night)

I had Wi-fi enabled for 12 hours, and the battery only dropped to around 85%. I have been on 4G for 5 hours now, and the battery is now down to 13%. I'm going to use a Wi-fi/3G combination tomorrow. Oh and I also have my phone rooted/underclocked to 900Mhz.

I've been using it for 3 days and have had no issues. Anyways its as easy as checking the standard limit if you ever wanted to revert back.

GSN Highest Up time...stable as ever

I just receive my extended battery today but wanted to show everyone my up time before I shut the phone off. Phone is just as stable as the 1st second of up time. Minimal apps....stock 4.0.2 ota, unrooted and locked bootloader.
Very happy with it and anyone who has wake locks and sod needs to remove some apps that aren't compatible.

My up time is currently at 820 hours!
Sent from my Galaxy Nexus using xda premium

just goes to show you how hardened the android kernel and frameworks really are. on my nexus one even i would routinely go 500 hours and still running as if it were just rebooted. my galaxy nexus is just as stable!

My up time rarely gets past 2 or 3 days! (It's hard for me not to flash a new ROM or kernel )

I'm curious if this would work with a ROM like Bugless Beast if I were to relock the bootloader after? I would go back to complete stock for the stability and battery life, but I really like the default wireless tether options from the AOSP build.
Quick side-note: I always noticed with my Nexus S that when I used it completely stock, I got better battery life than any ROM I used, including if I kept it stock and just rooted it. Not really sure why that is, but I imagine the same applies to the Galaxy Nexus. My girlfriend has hers completely stock and gets better battery life than I do all the time.

Cool serial number you got there...

720 hours and counting so far...hasn't rebooted once since I bought it!

I had my first reboot today. I was at the park with my girlfriend and dogs and she asked to take pictures of them so I handed her my phone and it unlocked but froze on the home screen. Lol, I told her it wasn't frozen and she probably did something wrong so when I grabbed it, it was on the home screen and went to the Google logo. Womp womp

I've tried about 3 different custom ROMs and stock, I think I've had a single reboot. Was it stock? I can't recall. I wouldn't exactly call it a crisis.

Ugh, I wish I could challenge those uptime scores! My Nexus has only crashed once since I got it and it was due to my own fault with charging with low voltage while using at the same time.
I just change SIM cards every weekend or every other weekend due to my trips to my girlfriend which requires a reboot. But yes, I love stability of Android!

[Q] New to the S3

Hey guys I just bought my S3 maybe a week ago and absolutely love it! I had it rooted and flashed within the first night. Mainly my question is though when I first got it I was running super quick and my RAM was rarely more than 50% full. After rooting I installed the Anakonda rom, setcpu, and juice defender ultimate to manage my battery.
Now I'm coming from an iPhone so I'm still adjusting to the difference in the phone but it seems like when I don't touch my phone i can go 15+ hours and not lose any battery but the moment I start doing anything it plummets. I used Titanium backup today to remove some bloatware and could just watch the battery disappear. On top of all this my RAM is constantly staying >50% full.
Any ideas? Is it bad to have the ram so full cus honestly I feel like the phone slows down (ie going to home screen and have a black wallpaper with no icons) then all the sudden it flashes and its all there.
As I said, Im new to the S3 and Android and absolutely love it. Just looking for advice so no flaming please ^.^
Edit: I would also like to say I use GoSMS as my texting app with the emoji plugin so my girlfriend and I can send those crazy icons back and forth. If youknow a better app (paid or free) that can use emoji please let me know.

I get better battery life without juice defender on this phone.

I get 14-15 hours with everything syncing, auto brightness, and no better saving apps, with 3-4.5 hours screen on time.
This is from today, notice on the right where it flattened out, I was taking a nap phone barely lost any battery.

[Q] Is this typical battery performance?

I'm new to the Verizon Galaxy Nexus (Toro), I just switched from a Thunderbolt.
So here's the issue: I am seeing much quicker battery drain than I would expect when running Carbon 1.1 (Android 4.2.2) or Carbon 1.0 (4.2.1). I'm going to try franco kernel today. Here are some screens showing stats. I replaced the stock battery (person who sold it said it wasn't holding charge) with Anker battery. I also disabled NFC wondering if maybe this battery doesn't support it.

Any advice would be greatly appreciated, maybe I missed something with installing the rom with this phone, as I said before, I am new to the Nexus.

You might can squeeze a little more, but </= 2 hours screen on time is generally what you can expect.

Seems pretty normal to me. With almost an hour of onscreen time 53% after almost 7 hours is pretty good.

Alright, thanks for the input. Sort of not what I expected, as this isn't much better battery life than my TB. Would anyone expect an improvement using just 3G? I don't typically use data on my phone anyone, as at home and at work I have wifi

Not a substantial one, no, but minimal improvement maybe.
EDIT: Unless the majority of your battery drain is coming from data usage.. Torrenting and such..

I somehow noticed a much better battery life in 4.2.2 than 4.2.1
I am running ParanoidAndroid 15th Feb release and AK 691 Pirates on my maguro.
I have disabled sync and only sync mails 2-3 times a day and complete sync once.
And screen on time between 2.5 to 3hrs is normal for the GNex.

Battery issue - Anyone else has same issue?

Hi guys
I've had my HTC 10 for over 2 weeks now, and as I decided to change from iOS to Android the first few days/week the battery would only last me barely 14 hours.
However, the last few days were very impressive with the phone lasting me 2 days and 12 hours with normal usage (no games and not heavy internet browsing).
But today something weird happened as I took the phone in the morning to go to work and at 10:30/11:00 my phone was down to about 60% without me doing anything to it and without a specific reason to it.
I will attach some screenshots to see if anyone had the same problem/issue.
I would appreciate any feedback you may have!

Did you try to restart the phone? Something is keeping your phone awake. A restart every couple of days is always helpful.

Yes, I did.
However, the phone's battery still only lasted until 7 pm. Which is really weird as I literally almost didn't use it...
Will see how it goes today

My battery life did not last very well either when K first got my 10. I'm an HTC lover by the way. In my experience, I've learned you really need to optimize the controls and settings after you purchase the phone to get the most out of your battery. I restrict a lot of app permissions that ask for location so my phone isn't constantly locating itself on GPS. Same for Wi-Fi. I turned off the auto scan for the Wi-Fi cause that absolutely toasts your battery. And then I turn off vibration feedback for touching keys just to conserve even more. I moderately use my phone throughout the day checking mail, texting, browsing the web, facebook, xda, altos adventures, a YouTube video here and there. I get to my office at 4 in the morning, don't get home til 3 pm and my phone still has anywhere from 45 - 60% charge. I think that's great considering my M8 normally has 15 - 20% when I would get home. Just tinker with the controls for a bit. Maybe I'm wrong but this is what worked for me

Yes, I understand and I have done so by restricting must apps and by having the same constant brightness and normally (as it happens today) the phone after 12 hours still has 50% battery. But it was that episode that literally was eating away the battery without me using the phone at all!
Thanks for the replies so far
