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.

Is anyone else's battery on crack?

Usually I can go a full 16 hour work day without needing an extra charge, then last week it started not holding the charge so well. In fact Tuesday it had 30% and I left the house for half an hour, and when I came back the phone had shut off and was at 0. I hadn't even touched it. I am on a mix of Wi-Fi and LTE. Anyway, that was odd. Now look at the battery usage...

Do you have a screenshot of the stats when the battery went all out of whack?

My android system has been going crazy the last week or so, usually would be at 5% our do but lately has been 40+ easy... been to lazy to wipe and re flash as I'm sure that will fix the issue, but lately I've been near power all the time so it hasn't really bothered me.

I flashed with Highonandroid and got 30+ hours. Probably could have gotten double if I didn't kill half of it installing all my apps back on.
What rom are you using?
On the stock image I was only getting 9 hours.

it looks like weatherbug and google maps take a lot of battery

i never truly understood why people boast of their battery life when they have the screen on for 10 minutes in 2 days

if you are not using a phone, turn it off and the battery will hold charge for many, many days.

** Community Battery Life Tips & Tricks **

While we have VOOC and (some of us) a spare battery lying around, we could all use more battery life when we're away from a wall outlet. So..
Post your battery stats/power consumption details along with any steps you took to achieve it.

Enjoy all.

Here's my battery results after a full day's use.
Stock Oppo Color OS
Stock Kernel
Google Now OFF
Low Manual Brightness
Bluetooth On
GPS On
Keylights Always OFF
Vibrate on Touch OFF
Greenify: NONE
Snapdragon Battery Guru: LEARNING
[There is a very small part where the battery charged while attached to a computer due to syncing over a few songs. I only seem to recall that battery going up by 1% at this time]
Anyone have any suggestions?

After installing snapdragon battery Guru i mentioned verry low speaker audio during phone Calls. uninstalling fixed the behavior.
anyone else.

That was with about 3 hours of gps on and using Google maps and a route planner for my deliveries today. I don't know if that's good as I've yet to use it like this before.
I have all off screen and on screen gestures turned off except the 3 fingers for screen shot. Auto brightness and wifi was off today as well.
The other day I let my phone idle for 9ish hours while I slept and I lost 4%, that was also putting the cell data to edge though.
I also use the greenify app, not the built in greenify. Haven't messed with the built in greenify does it work the same way?
Tapped out on my beastly OPPO Find 7a

This has got to be a bug...
Unplugged, drove to work and noticed no drain on the monitor.
The phone was trickle charged by my router though overnight, not through the OEM charger

I disabled the gestures, that helped a lot.

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

Good battery or software bug? Still on 100% even after 1hour 25 minutes

I think its just a bug, mine seems to stay on 100% for a long time too. It does drop eventually. The battery life is very good on this phone though. I've never had it run out during a day yet. It does seem to better reflect battery use at it gets lower.

Yes you are right after 90 minutes it's dropped to 99 and 98, I thought I have to restart to get correct reading but didn't
Sent from my SM-A705FN using Tapatalk

I have same issue. Stays at 100% after 30mins or more of usage. As soon at it drops to 98% battery drain becomes normal.
I did the calibration reset code *#0228# and it didn't change a thing.
Battery life is good on this phone but nothing impressive.

Probably needs a few charge cycles for the battery to calibrate properly, happened to me too.

Still going strong, no power saving , 4g all the time , Bluetooth all the time, alot of games, Facebook and YouTube

My battery life

this phone is excellent on battery life.
when i first used it and charged it to 100%, I noticed the same thing, and was confused, checked to see if the phone froze, etc. But then I started to feel invincible from the overabundance of power. LOL.
