Hello,
I am using Nexus 6P with the unrooted N6F26Q build of Pure Nexus ROM. I have always had decent battery performance of this phone with my general usage. Recently I have moved to a new geographic location and I see a rapid battery drain while the phone in a particular building. I do not have cell phone network here, so I have AirPlane mode turned on, but I use WiFi for internet connectivity. My observations are as follows:
1. During the day time, when I am in building A, there is no battery drain. I don't use my phone much and the battery level does not drop by much.
2. During evening and night time, I am in building B, which has a different WiFi, the battery immediately starts to deplete rapidly and in the morning I wake up with a dead phone.
3. Suspecting that the WiFi might be the cause, I tried to switch WiFi off at night, but I still found my phone to be dead in the morning.
I captured the bug report data and tried to analyze it with battery historian, but I don't have enough experience to point out the cause.
This is what the battery historian graph looks like.

Same graph from another bug report, when the WiFi was turned off during the night:
Can someone see something unusual in the graphs?
I can share the entire bug report via PM if someone wants to take a closer look.
Thank you.

It seems a lot of people were saying the Atrix had very good battery life, but after flashing one rom and kernel then back to stock with stock kernel. It seems my battery life isn't the best, it may just be me or actually the phone.
So, is it just what I did to the phone or the phone?
I'm at 60% with 5 hours and 12minutes of use.

You used a lot of wifi and 3g. It looks like your phone could make a workday from morn til night on a single charge. How much battery did you expect? 3days? You can 5 days if you just leave it in your pocket in airplane mode.
I voided my warranty and your mum.
My Atrix 4G drop 30% after 1 night (2am - 7 am)...
I checked batterymix software, the fingerprint service comsumes about 70% of the TTL energy eventhough i disable the service and set security screen to none.
How can I turn the service off permanently?
I'm using (3.14) CRUST v0.7 with [email protected]#1 kernel....
Srry because I just bought the phone (used) yesterday!
Guys, is there really a need in creating yet another battery life thread?
I have personally wrote a complete thread with all known fixes, as did a number of other forum members.

Your problem isn't unique, please look at what others wrote before starting from scratch.
Hi I have a question, is normal that our devices eat so much battery, having the brightness in 0% ?

I think the battery statusbar is wrongly coded... I have the same results as well all the time.. Even when I don't using the screen (during night), the statusbar still shows up about 30% battery consumption...
The thing that affect battery drain the most is 3G mobile data communication in my opinion, because just turing it off, the phone got juiced up for more than 3 times as usual...

Not only turning off the 3g internet, but using for calls as well. that is why i started a discussion thread for that matter but no one seemed to respond to that. maybe it was too large to read??

Saw your thread, but I'm not that sure how I would comment or respond :X, as there doesn't seem to be any solution to fix it.
Hello, 3 days ago I've installed CM10.1 nightly build from 2013-07-25 on my friend's Galaxy S III (international), now his battery life is really bad and he's complaining on me, any way I can improve the battery life?
Here goes a screenshot (as you can see, he wasn't even using the phone when the battery just dropped 50%):

Cyanogen mod roms are known to drain battery much faster than touchwiz.so you cant really expect the battery life to be the same as on stock or stock based roms. you may improve the battery life by using an app called Greenify. it hibernates apps so that they will not run in the backround. this can help considerably. also make sure to turn off gps , bluetooth, wifi. and mobile data when not in use.
well first tell your "friend" that thats how things are in AOSPs. Secondly use differrent kernels and proper setting to get max battery (tutorials are available) plus greenify apps you do not use. And the usual killers as GPS/WiFi/NFC/3G use only when needed or turn them off..
Something is extremely wrong there. Get a normal usage BBS dump and post it here. Also take screenshots of the BBS pages.
Also post a screenshot of your battery stats page (one that shows which apps drain battery).
Hello , i'm on an investigation why did my phone died last night. Basically i left it on 33% and in the morning the phone was completely dead! Usually it never took more than 15% overnight. I was unable to determinate the problem via BBS because as you may know BBS doesn't really work on 4.4 Kitkat (even if set as system app). The only thing i can show you is the build-in battery monitor graph. See the red section - no screen times , no waking , no GPS , no Wi-Fi but the graph is still going down. I always keep an eye on my battery stats and overal phone health but this is the first time i'm experiencing such issue.

That graph is essentially useless/tells us nothing whatsoever. I'd be replacing the battery (might want to do a clean install of JB stock first to make sure it isn't a KK rom problem).

That graph is basically all i have without BBS.
Yes, I know that. And as I've said, it's useless. What exact information are you expecting anyone else to glean from it that you haven't already done yourself (We're not mystics) ? It's a simple/basic graph, it provides simple/basic information, which won't answer your questions/give you info to enable you to solve your problem.
Stock kernel?Any undervolting?Maybe it freezed and that drained your battery.
Hello there, I'm new to the Galaxy S2 forums, I before had an Xperia Arc.
I have a problem that happened just last night. Last night I turned off my phone and left it, didn't touch it. That was about.. around 1 am, right now, 10am I woke up and turned it on. Samsung logo, ROM boots etc, I check the battery and I have 8% left. What??
I took these screenshots, Wakelock Detector screenshots would be useless as it only shows stats from when I turned it on, and everything's normal.

As you see it lost that huge amount of battery while turned off for no actual reason.
I'm not sure it's an "overnight" issue, I've noticed a random and huge battery drain on power off/on (even on reboots) on 3 different Samsung devices, using different kernels and roms.
[EDIT] Sometimes the battery even slowly recharges by itself with time, so maybe it's a battery stats-related issue [/EDIT]

Well yes you're right too, any idea of why this on/off huge battery drain?
Use battery stats plus..
And check what is causing battery tp drain
Difference in battery level after reboot is quiet normal thanks to the fuel gauze chip we have
