[Q] lollipop battery problems

Does anybody know if the .726 firmware has any issues with low battery life and overheating?? I have the update available but i didn't do it because i red that many z3 compact-lollipo users had problems with battery life. Thanks

Battery Issues
I had an issue when I installed it, battery life was terrible the first day. Something about Mobile Radio Active... I turned off Queue Background Data in Power Management and it seems to be better now. I haven't had any issues with overheating, although I might not be the best person to ask, cause I'm not really a heavy user. Just every day apps.
I installed the update immediately because I got sick of not being able to do anything with my sd card! I don't really see any other reason, so if you don't wanna risk it, don't update!
EDIT: Ignore what I said, battery is still terrible. It appears that lollipop's battery stats is just bad. There is something wasting my battery and I have no idea what

I upgraded my gf z3 to lollipop and the damn phone overheats constantly and has an insane battery drain. It usually drops to 40% by 8 or so for her on normal usage (she barely uses it) but since the update it dies before 9pm. There is something seriously wrong with this and I'll continue looking into this. Really aggravating. And the heat is unbearable.

[Q] Huge battery drain

Hello XDA community. I bought my HTC One about 5 days ago and I have noticed a really bad battery drain.
I know this isn't the first thread complaining about this issue, 'cause the first thing I did was search for a fix to this problem. Sadly none of the solutions I found worked for me.
When I use the phone like a normal person would do (Browse some web pages, check facebook, listen to music etc.) the phone discharges really fast (Like 1 percent per two minutes or three). And when I leave the screen off the battery doesn't consume that fast (I left my phone uncharging when I went to sleep and after 10 hours it took about 10 percent of the battery which I think is pretty acceptable)
I've tried:
- Calibrating the battery (http://forums.androidcentral.com/ve...ry-charger-reset-procedure-htc-one-m7-m8.html)
- Using AppsOpps to prevent Google Play Services from waking up the device.
- Using Greenify to hibernate the apps that may drain the battery.
- Using Amplify to manage and edit/disable wakelocks, alarms and services.
Basically everything in this thread (http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884)
- Changing the ROM
- Flashing a new Kernel
- Perform a Factory Reset.
I'm currently using the AndroidRevolutionHD Rom based on Sense 6 running Android 5.0.2 and using the ElementalX kernel.
Here are some screenshots of my battery usage:

Android OS WakeLock from Hell

Hi,
When my My MotoG 2 is connected to WiFi Android OS sometimes keeps the device awake, eating up my battery until I restart the device. It just happens sometimes, not always.
My device isn't rooted yet due to warranty. I disabled everything I could in Settings>Applications.
Any advices?

Hum, maybe Ambient Display is the offender, let's try it....

Well, I've been testing it in the last few days, and it seems to be solved.
I turned off "Ambient display" and installed Glimpse Notifications for similar funcionality. Now Android Os keeps the device awake few minutes instead of many hours.
Hope it continues this way!

This is not how you troubleshoot wakelocks.
You need an app that analyse the cause of it, like Better Battery Stats.
Once you installed it, you've to leave your phone for around 2 or 3 hours without using it. Then you'll be able to see what causes the wakelock.

Please, read before reply.
Without root these apps are useless, that's why I used such a "brute force" approach. And I shared my results here just in case someobe else finds the same kind of problem, not to teach how to troubleshoot wakelocks, there are plenty of tutorials on this subject around.

Galaxy Tab S2 9.7 T815 battery failure or probably motherboard issues

Hi
i guess i've got a major problem.
while normally using my galaxy tab s2 9.7 t815 it start becaming really hot in the center-right part and battery charge fallen down very quickly. While this was happening I turned it off (i mean shut down/power off, not the only black screen) to let it cool down. Even when off it was always very hot and when i turned it on half hour later battery was something around 20-30% lower. Since it was not charging either, I downloaded Gsam battery monitor just to discover that the ongoing drainage cannot be stopped by the charge: without the charger connected, gsam said a little more than -2000ma, with the charger around -1800 (figures where not stable).
So battery goes from 90% to 0% in less than 2 hours i guess. Now i'm not able to turn it on because it doesn't charge (it always stays at 0%) and it turn off immediately.
Today i've opened it and the component that gets hot is the one between battery and sim/sd location (hope the image added below works). Checked and unpluggled/replugged every connector nothing changed.
Tablet is rooted. I've never used it hard: i use it mostly to surf the web, email, few minor apps, no games at all.
Thanks for your help

Battery suddenly drops to 1%

Hello everyone, today I woke-up with my phone pretty much dead, with only 1% of battery. The weird thing is that before bed, the battery percentage was around 70ish percent.
Here's a screenshot of the battery usage:​
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Some details to help me figure it out the issue:​
Auto optimize daily is on.​
Auto restart at set times is on (it restarted around the time that the battery percentage drops to the floor).​
Adaptative power saving is off.​
Background usage limits is configured properly.​
Any help will be appreciated, thanks in advance!​

it's possible the Google services was running (updates and such) and used up a lot of the battery. Google being the OS developer tends to run quite a lot of things in the back without users knowing, and this is quite normal. As to draining such large amount, is your location in a poor data coverage area? if you are, then the phone likely was using extra battery to strengthen the signal. Note that even with wifi connection, data is still used for some activities by the phone.
if this keeps persisting then Google is probably not the culprit and you'll want to report the issue right away to samsung using samsung members app > get help > error report. just be sure to see the drain and immediately report.
Also, I've seen some users install 3rd party apps to track in finer detail on what is using the battery the most. I myself do not know as I don't use it, but you can easily find some recommendations on Reddit i think.
