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...

6 hours screen on?

Sure sure it's with light use, but just the fact that it can hit 6+ hours screen time after more than a day and a half... sits pretty well with me.
No games, 30% screen brightness, 74 mins of calls, quite a bit of texting & whatsapp, 30 odd mins browsing, wifi 100%, sync on, only 1 widget.
aokp, lean kernel, undervolted, K6, extended battery.
Loving this phone!!!

Not bad at all! Especially considering 74min of phone calls.

NICE!!! Can't wait till my extended battery comes in.

Nice. I've had my extended battery for 2 days now and I am seriously impresses ed with it. It on my drive home I'm at 65% instead of 30%. I really think the extended battery should of come stock.

I got a similar 6 hour in airplane mode. I was watching a movie while roaming on vacation.
Verizon stock rom. stock battery.

Even stock SGN makes wonders with battery on Wi-Fi But still your stats are truly amazing

OP did charge the phone for a bit....like 3 times don't know for how long....but nonetheless amazing stats...

No, he didn't? Look closer on first screenshot. There is no sign of charging on those lines below the graph. Those places where graph line goes up are pretty normal and that doesn't mean device war charging.

There's no charging there.
Line is going up for a little, but that's normal and it often happens in my phone too.

Nah I didn't charge it at all, as the other guys pointed out. I remember my battery dropping to 4%, I then put down my phone and when I came back later on, it was reading 5%. I thought I was going crazy, but looking at the graph now I see it really did happen. It raised from 4% to 5% and stayed there for a bit before dropping to 4% again.
Anyway, I hope this wasn't a one off... it's not doing as well today with the same usage. We'll see...

Actually, the phone calls don't do much damage... You should be able to talk 11hours on this phone apparently...

I am very jealous. I am lucky to get 3-3.5 of web surfing.

With standard battery, you can get almost 11 hours screen on time (by doing nothing):
http://forum.xda-developers.com/showthread.php?t=1366878&highlight=max+battery
So, that's the limit
My experience with extended battery, 2000 mAH, GSM, I could get 4 and a half screen on time with 61 hours stand by time. For sure, it can go down to 6 hours or more screen on time if I down the standby time. All with stock ROM, stok kernel, un-locked
It is not difficult to achieve that knowing the limit, all depends on how you set it up and how do you use your phone.

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)?

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

Strange battery issue

Sometimes my battery is awesome, and sometimes it just sucks.
This was 7 hours overnight, zero use. No wakelocks, and yet the battery drained really fast. Usually it's about 1% of drain per hour and a half of idle.
Any ideas?

And the awake times are for Twitter, Facebook, email, weather updates, etc.

1. well twitter and facebook are battery hogs.
2. I have had battery issues with email (only exchange accounts)
3. which firmware are you using?

Nk3,
And it isn't always like this. Some days are fine, some days are awful.

And I use tweetings for Twitter, no the actual twitter app, if that makes a difference.

My battery is terrible has been since I got it

Battery Issue
Well, I see no reply on this thread for a long time. I have been facing some battery issues as well. And this issue was there since before the 5.0.1 OTA update which I received 3 days ago. I will post some screenshots, but here are the usage statistics. I have been struggling to get a full day of battery with very moderate to low usage. The general amount of screen on time I get has been about 2-2 1/2 hours at max. I make some phone calls over the day and since that uses the radios, I take that as a reason too. The general call time I use my phone everyday is about 1-1 1/2 hours. Other than that, its not much usage. I am posting the most recent screenshots here. I unplugged my phone from charging at a little over 1.30 PM and have lost 11% in about an hour. In that duration, the only thing I used my phone for, was 43 minutes of voice call. Is this normal for this duration of calling? The screen has been on for a maximum 5 minutes at best.

Oh yes, and I forgot to mention. I do not put the screen on auto brightness. I usually keep it at a very low level, say about 20-25% and only increase it manually if I am outdoors.

[FP4][LOS20] Absolutely atrocious battery life. Phone dies every night it's not plugged in

Hi guys
I moved to LOS in the hopes of improving battery life but it's been pretty bad. I'm at my whits end. I tried using PhoneProfilesPlus to turn off all sensors and radios overnight but it didn't help. My phone literally burns through battery after every even small charging cycle. I used GSam Battery Monitor but couldn't identify any specific app to be the culprit either.
Last night I even used "Battery Tool" to stop most all apps as well as "SaverTuner" to change the Doze mode settings but even still I get the following usage curve:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Btw the times seem to be completely off too. The last charging spike was around midnight.
I also noticed that Wifi won't show as "off" in the stats unless I reboot my device. But doing that didn't change anything either. As you can see, after I rebooted in the evening, the curve was practically flat. After charging a bit and unplugging before sleep though the phone immediately started draining again.
Any help is very appreciated. It seems I can't go back to stock bc of the A13 bootloader but battery life wasn't much better on stock either.

You also have other helpful charts in Gsam.
What do you mean by "unplugging before sleep"?
Turn off your phone completely overnight and compare the charge before and after.

I meant that I don't leave the phone plugged in overnight. Sadly I can't really gleam anything helpful from the statistics. I'm going to try and charge it to full before this night and set a custom reference point

Looking at that graph, do you have your screen always on? The 2-3 hours around midnight show screen on, but no battery drop. I assume you had it on charge at that point?
What charger are you using? I use an Anker 5 port Quickcharge 4 charger with a USB-C cable that has an LED display to show the charging wattage. I usually get 18W (9V*2A) which pushes charge in quite quickly.
I can't speak for LOS20 as I'm on stock A12, but the battery does seem to discharge faster than you expect.
I use AccuBattery to monitor the power usage and charge/discharge history. Put it this way, I find I do a number of smaller charges through the day. Driving along, I'll have the phone hooked up to the Android Auto slow charging it while I'm using it. I get home and I'll stick it on charge for 45 minutes to boost it up from 20% to 80%.
The rated capacity of the battery is 3905mAh, and AccuBattery is estimating my current battry capacity at 3443mAh, a reduction of 12% in 9 months. That's with only charging between 15% and 80% most of the time. I'll give it a 100% once a month or so.

Thanks for your replies!
I'm thinking something is really wrong with deep doze in my case. I charged my phone fully and got to 50% in a day's use. I made a point of not plugging it in at all because normally you'd expect it to survive on half a battery but no dice. it just starts burning through battery suddenly.
I'm honestly unsure about this graph too. I certainly didn't use the phone and the screen until 2am. I might need to look at other apps too but that doesn't change that my pone went from 55% to 0 in about 6h.

You didn't have to use. Apps and services do it for you.
