I'M using Oxygen 0.2.2 Beta Rom. Yesterday I recalibrate my battery, closed unnecessary programs, turn off wifi, 3g, gps and bluetooth. Morning I checked battery level and shocked battery leves was about %75. I checked if there any memory leaked program but I couldn't find something like that.
Display used battery percantage dramatically high?
What is the problem? Screen was turned off naturally.

'My Battery Kills Me' - sounds like the title of a cheap horror film - LOL
How long is 'overnight'? 8, 10 hours?
25% in that time sounds quite reasonable to me.

@cr1960 25% over 8 hr with wifi and 3g off is not normal and if you experience this i would check what is causing your drain.
@yapay Install current widget, place it on one of the home screens and set it up to wright to the log every 5 min. Then turn your phone in to flight mode overnight and the next day check the log, if you have more than 1 mA usage regularly during the night there is something using to much power. Install a monitoring app from the market and let it run during the night to find out what.
If it's mostly around 1 mA than your problem probably is gone after another charge.

Screen is very high for only 1.5h ish. Looks looks like you have high brightness settings and a lot of white/blue images being displayed.

There is a misunderstood. I checked battery status after woke up and that was 60% display usage. After that I used phone during breakfast and later my battery was 18%.
Something is wrong...

Jelly Bean battery life issue(?) for a newbie

Hello all!
I'm a brand new and happy user of the galaxy Nexus. Bought it two days ago and of course I started to play around with it quite a lot.
It was not new but it was used rarely, especially in the past 3 months. The phone itself is five months old.
I am just wondering if it is normal that the battery drains so quickly. Considering the fact that as a new toy i am using it quite strongly I still find it too fast eating the power.
The other thing is that could be in relation with this is that I think it is very strange seeing that something keep waking up my phone when it should be sleeping.
Let me attach a screenshot about battery stats. Please ignore and forgive it that it is in hungarian. The important thing is still visible.
What shall I do?
Thanks in advance!

How much screen-on time? With crappy signal and a LOT of awake time, I'm not surprised at all by 15hrs of total time.
You have an app (or a few) keeping your phone awake quite often. That alone will drain the battery. Try something like "Better Battery Stats" to see whats keeping the phone awake.

Yeah I forgot to mention that I had very bad reception for that time in the mountains. Screen on time was around 45 minutes - one hour.
How shall I look for apps not letting my phone going to sleep? Any free subsidiary for Betterbattery?

If your getting bad signal I suggest turning off your sync unless you need it, most of the time battery life is a result of the user or the apps they use better battery stats is a good app to find out what apps are keeping your phone from sleeping, also just a tip posting about battery life can get nasty responses good luck man

Judging by the wake bar, go to Latitude and in Location Settings sign out of Latitude. Google Now still works and you won't get your device constantly updating your position while screen off. I believe when you turn on Google Now it automatically signs you into Latitude as well.

Just trying to find out how to spy out apps using my phone than they should.

get BetterBatteryStats. I am sure that you'll just see googlelocationupdateetcetcwhateveritwascalled at the top of wake locks

Ok now I am quite sure that it's the wifi that keeps waking up the device. After testing two days with wifi on and yesterday with wifi turned off it seems obvious.
I also find another topic where an other guy found the same answer... Very strange and very annoying.
With wifi:
Without wifi :
Both test were running during night when the device should sleep as well

I think the betterbatterystats is the best way to go as mentioned earlier. You might find that it's an app that is calling the wifi connection that causes wifi to appear neat the top of your stats at present.

[IMPOSSIBLE] Battery drain while the CPU is in Deep Sleep [BetterBatteryStats]

Hi,
i managed to get my standby drain on unrooted stock 4.2 to 0,5% (WIFI) to 0,8% (HSDPA) per hour with disabling some stuff that i dont ever need.
Market notifications
Latitude
Google apps like Currents, Play movies, Play books etc...
This is great, but sometimes after usage it still felt like the battery keeps draining as the phone is in use with the screen turned on.
What now happenend is really weird:
I did set a custom reference in BetterBatterySats and left the phone on the table for 1 hour. No unneccessary apps running in the background. But it drained 7% in this hour. As you can see in the screenshots, the device was in Deep Sleep most of the time and there are no noticeable Partial Wakelocks.

But how the heck is it possible that i lost 7% in one hour while deep sleeping? Is there any sort of app that can tell me in this particular case what went wrong?
Any info is highly appreciated.
Best,
ras

k9 mail seems to be one of the culprits

nope. it polls 2 accounts every hour anf therefore uses cpu time of approx. 0,4%. thats even even the case in that "awesome battery life" area seen on the last screengrab. a total of 15 sec. cpu time can't hurt that much.

This may sound silly but did you try just to restart the phone?

im pretty sure that this would fix it.
but because this happens from time to time (though this is the first time i can document it because auf BBS) i want to know whats the cause of this. it is pretty annoying to leave a phone on the desk and to find it drained empty a few hours later. this would have happened if didn't pick it up after one hour.

I get a similar problem too. Only way to clear it is a power down and restart.

Well, first of all, can we really be sure that those 7% aren't within the battery measurement margin of error?
Considering of course stuff like temperature, sensor's reading delay and other electrical/chemical/whatever stuff the battery may go through after heavy draining like you show in the graph?
I really don't think that % stats are that accurate, but that might just be me.
Some guy disassembled his Nexus S and measured the energy drain with accurate reading devices. Maybe someone should do the same on the Galaxy Nexus. Because if one software says there's no cause of drainage and another say there was some drain, maybe one should confirm which software should we rely the most.

maybe it happens because the voltage still gets down because of heavy use before. if this is the case the drain should stop at some point and the battery should not die completely.
i will def. keep an eye on this.

Its the fundamental problem with android and our battery technology.
One of two things need to happen, Google needs to get their act together (think project butter but with battery) or the OEM's need to start providing better battery technology. Its ridiculous that over the past 3 years there have been NO significant battery technology improvements. Yes, processors are becoming more efficient and using less power, but that is only going to take us so far. **** needs to happen and Google needs to press it.

I am having the same issue... Huge battery drain happens in my case at the battery range of 0%~20% and 80%~100%.

I am now using the latest franco kernel v335 and I think it somehow reaolve the issue. I will monitor and report.

Battery is ****ed up.

I was always unsatisfied with my battery life, but now it's gone too far!
1. No matter how long I charge it, at the very second I unplug it it goes down to 99%.
2. It doesn't even go down correctly, one moment it's 65% and the other it's 58%. Always.
3. It drains soooooo fast even though I do nothing with it!!!!
Here are some pictures
1. This is 17 minutes after unplugging it, all I did was to put music on [earphones] and check if my girlfriend was online on Whatsapp.

2. That's after a minute and a half, 2% less, doing nothing but listening to music with my screen off!
3. One minute later..
4. Sixteen minutes later, phone is idle and untouched [not even music, I started my shift]
5. Again, idle.
It lasts 3 hours tops!!!! What the hell do I do.

This app already told you the culprit! Your getting wakelocks so an app you installed is keeping the device awake all the time. The rest is for you to figure out partner . Use the search function on XDA and you will find all the info you need.

Ok might be but to the level where the phone doesn't last 3 hours? That's not cool. It should be lasting more even with heavy using.

yeah you're right, it should last more anyway! maybe it's the rom.. what rom are you using? or maybe the battery failed. it happened to me with another phone, basically i was in the seaside with about 38°C the phone was boiling hot, the battery was fully charged but in about 20 mins it was at 5% without even using it then it died. since then that battery never worked again and i had to buy a new one. do you remember if you had a similar situation or if your phone overheated for any other reason (maybe while charging or near a heat source)?

It got heated a few times but not too hot, and besides, I read that it happens to everyone..

HUGE battery drain on my OP3

Hi everyone,
Since a few days, the battery life of my OP3 has been divided by at least 3, with a normal use, it lasts no longer than 5 hours, I now usually charge it twice a day, and during the night, it lose about 60% battery, here's a screenshot.

Recently I've been playing Pokemon GO a lot so I understand it can damage the battery, but none of my friend have experienced the same issue, yet they have cheaper phone than the OP3.
I did a few research and didn't notice anyone with the same problem.
Also I contact OnePlus support but they are unqualified so I don't want to lose more time with them.
Yesterday I wiped everything on my phone and reinstalled Oxygen OS, during the night I lost about 10% battery, that's a big progress but it's still abnormal, and I have lost about 10% again by using my phone a bit after awaking.
So I tried everything that is in my knowledge but there still a big problem with the battery of my phone, anyone has a solution for me ?

I note from your screen shot you are running both Facebook and messenger, and from your post pokemon go, notorious battery hogs I suspect they aren't helping. But if this drain is a new phenomenon what have you installed on recently?

Yes I know Facebook, Messenger and Pokemon GO drain a lot of battery, but I charged my phone at 100% before going to sleep and closed all the apps, so these apps wasn't running in background during the night, I just received some notifications and messages during the night, that can't be what drained so much battery... Also I've been using Facebook and Messenger on Android for 3 years now, and I'm playing Pokemon GO since July 6, but the huge battery drain started only a few days ago, and I started to notice battery problem maybe 2 weeks ago.
I didn't installed anything special recently, I'm just using my phone like I've always did...

What sensors have you activated? GPS? NFC? Bluetooth?
Did you try and install Better Battery Stats? Or Wake Lock Detector?
Gesendet von meinem ONEPLUS A3003 mit Tapatalk

I only activated GPS.
I installed BetterBatteryStats about 1 month ago but I don't really understand the stats in it. I installed it because someone on another forum told me to install it and post screenshots after a day of use, that was a few time after I received my OP3 because since the beginning I noticed the battery life was anomaly short. I've recently uninstalled it.
You can see the screenshots here
A technician from OnePlus called me and advised me to install Snapdragon Guru so I did it, I will see if it changes anything.

Well 3% per hour is not so bad, I have it, too. GPS is most time in energy saving mode and Bluetooth is on as I wear a smart watch.
Perhaps you should reinstall BBS again and we will have a look at the newer stats.
GPS can be a real drainer.
Gesendet von meinem ONEPLUS A3003 mit Tapatalk

Now it is more like 10-15% per hour...
I'm downloading OOS 3.2.4 but the mirror is very slow so I'll have it this night I thing. I will wipe everything again, install latest OOS and install BBS again, we'll see then...

So yesterday I wiped everything again and reinstalled OOS 3.2.4 this time, then I went out to play Pokemon GO so the battery emptied in about 4 hours which was normal while playing this game, anyway, I charged it at 100% before going to sleep and put it in airplane mode and look at the result :
So now I'm sure of one thing, the battery doesn't drain itself for no reason. Yesterday a technician from OnePlus called me and told me about turning data off during the night (that why I put my phone in airplane mode). If that is really the problem, I don't understand why... Why after 3 years using Android, data suddenly drains battery like never before (without changing my way of using my phone) and why it does that to only a few people...
Today I used my phone normally, it lasted almost all the day, that is a big progress, but it is still ridiculous compared to my old phones that lasted 2 days at the beginning. I took a lot of screenshots when the battery was almost empty so maybe someone can help me to analyze what is the problem with the battery consumption.

Did you ever find a solution to your battery drain? If so, would you like to share this solution?
