Battery life is beast.

OK I hope someone finds this useful and/or can verify. I was one of those people getting awful battery life, meaning lucky to last 8 hours from 100% to 0%. The "Android OS" process would take hours of CPU time. Now it will take up maybe 30 min over the course of the day. Here is the only thing I did between the time it went from bad to good. I changed the wifi sleep policy. It is by default (for me at least) set to never. I changed it to "when the screen turns off" and left it there for about an hour. Then went in and changed it back to never. From the point of doing this my battery life has been great.
I know it sounds strange but it seems to have worked for me so I thought I would share.

Yeah, battery life is going to depend on services that are running on the background. It'll be different from people to people. You shouldn't exchange your phone because you're not getting the same results as someone else.

I dunno how you guys are getting that battery life. I think there must be something really messed up on my device. Stupid "Android OS"!
Screenshots show at 38% after 6.5 hours off the charger.

I'd post a link to some screenshots if I could. But my Android OS is at 27% and display is at 47%.

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.

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.

How is everyone finding the battery life on CM10?

I would have asked this in the thread, but I'm new so can't make posts there. Anyways, for me it's pretty terrible.
It's been 9 hours and 51 minutes off charge and my batter is at 40%. The screen on time is 34 minutes and set to autobright. Anyone else getting anything this bad?

How long have you been using this ROM for ? It usually takes at LEAST 2-3 days of use before battery stats improve. That goes for every new ROM you install.

The battery in cm10 is great I'm seeing 1% per hour in standby just run a few cycles it will calm

I've been using p12v2 the day it came out, but I've been using the ROM since p5. Should I just run it through a few full cycles then?

Ah, I forgot I installed that. Deep sleep is at 58%

I recently had quite good battery life on eprj cmx(10). I got about 3.5h screen-on time, and in total a time of 6.5h. Look at my quote below(yip I just did quote myself).

I did actually use the phone as you can see. This is just very normal usage. Browsing, xda and flipboard mostly. Also running on the oc version and lowest screen brightness(which is still quite bright).

[Q] Battery issue??

Well I feel something is ****ed up with my one x.
I charged it yesterday before I went to sleep and left the device off.
And now when I woke up, I turned it on and saw my battery is 96.
Ok so I left it with the screen off until now, about 3 hours
And I see the battery went down to 83% (When i started to write this topic I were 86%)
What is wrong with the battery?
Never heard about a phone that the battery is still getting down even when its off

Post the battery screen with the usage graph on it. I suspect you have an app preventing deep sleep.

I will try to flash the new version 8.1

Battery charge level went up without charging?
That's very strange, but during that time the screen was on and it wasn't sleeping.
It's all a bit odd.

Did I get a defective battery?

Just got my s3 like a week or so. I made a mistake and not charge it initially (thought it was a myth). I used my battery all the way to 17%. Now my battery only average up to 2 hours screen on. My sister who also got the phone as the same time has about right hour screen on time. Did I screw up or it's just my battery being defective
EDIT: attached is the battery stats

What's brightness set to, and what are you doing while the screen is on? You on WiFi most of the time?

Well, when I'm in door, I use low brightness most of the time. Only when I'm outside I would use auto brightness. Since I'm in wifi zone most of the time, yes I do have wifi on. I mostly use my phone for twitter, web browsing, and youtube, nothing heavy like gaming or benchmark.

Hard to say if its defective but I've definitely seen a lot better battery. It might not hurt to try and get a new one.

you should calibrate your battery a couple times once you get the phone. do it a couple times and it will fix itself. also check all your syncing settings. this phone will deplete a battery in 5-6 hours if fully charged and phone brightness is up all the way while watching videos.

Calibrating batteries is a myth from the days of older battery technology. Draining your battery to 0 on purpose is actually killing your battery faster because you just used up one cycle.

There's a bug on stock that makes cell standby much higher than it really is. So I wouldn't worry too much about that.
Also, Google Chrome is a huge battery killer for some reason. Consider switching to a different browser?

Still having the original battery in my vibrant and getting 8-9 hour charges while killing the battery 100% and charging it up once a week does nothing? Same thing for my g2x. I get about 10-11 hours on the thing daily original battery as well. If anything and you're not rooted to delete battery stats, its a good thing to do a couple times. I don't think I have hurt the battery at all, and if anything they still last very long...
