It seems like my battery won't idle after it drops under 100%. I can leave it off the charger at 100% and it won't drop. But after that it'll drop 2-3% every 2-3 hours I don't touch it. What gives? Looking at the graph there is no wake locks period. It just slants it never flat lines it seems like. WiFi is not on and it deep sleeps. But the battery drops over nothing.
Left it over night at 71% and it dropped to 68%.

Mine does this too, I have noticed it since the start with every kernel/ROM
I can leave it for ages or even use it for a while, and it stays at 100% but below 100% it doesn't do this
However I have noticed that this occurs more on some kernels than others. eg. Bricked which I am using now, does not last as long on 100% and goes down normally from there.
I have read people thinking their battery life is amazing at 100% but honestly I think its a bug or something in the reading
Please correct me if I'm wrong

Its a possibility I never had this expierence before 4.1.2 got put out. I honestly think that it was a bug introduced. Or something not entirely sure. Thanks for participating.

Honestly, I have noticed it since the first few days I had it, on 4.1 and 4.1.1 (I got mine on release weekend)
No problem mate I am actually glad someone else has noticed it as a bug or something, not amazing battery life lol

Issue is I've never had this till just recently. It'll idle perfectly after a full charge at 100% but start messing with it and it'll drop 2% every time I let it idle every 3-4 hours. Hell not even that long some times. Using betterbatterystats to see if its an app. As I see that the CPU time using States doesn't match the display time. So its awake when the screen is off and isn't showing up in the battery graph.

Is it not normal for a battery to die even if a device is not being used? I don't see how it would remain the same % if its not plugged in.

Third day with my Nexus 4, and battery life seems to be just like the old days of my gnex ? I am really surprised. Tried different rom and kernel combinations. My battery is draining fast. Cant blame any app since i have been running the same apps on my gnex as well as my sold s3, experienced an impressive battery life on the s3. Even tho the s3 and the N4 has the same 2100 battery ? Any explanation? Ty.

Tried to read throught the threas. Nothing that helpful ! I have 36 percent left atm and my screen time is only 55 mins. Lol ?

Wait until new phone syndrome wears off.
You've only had your phone 3 days, and your still flashing new roms, which sucks up a lot of juice. Let it settle for a few days.
Also a 4.7" display sucks down battery. My phone last all day no problem now that I've had it for a few weeks. First week it wouldn't last 6 hours... because I used it for 6 hours screen on constantly.
Hey I've searched for help on the subject all over and. I'm not seeing anyone with this problem, on the contrary everyone seems to be doing better.
Anyway I got the OTA update to 4.2.2 from the. General forum a few days ago and flashed it without much consequence and everything seemed fine. I reaquired my root but I have noticed my battery is losing charge way too fast doing light browsing and use.
Checking battery use I got 2 hours of screen time with 30% of the battery and again this has been simply browsing sites with pure text. As I'm writing this it went from 70% to 68%
To list a few key things that have happened that might be important and I'm hoping anybody can help or give advice.
1) I stupidly forgot to wipe cache and dalvik before and after flashing the update, when I remembered I went to recovery and did this
2) I rerooted
3) On Friday I fell asleep using it and when I woke up it was completely drained, honestly I don't even remembered what I was doing cause I had a bit too much wine but I think I was playing an emulator and when I woke up it wouldn't even turn on so I charged it back to 100%
As I write this now I think back and problem seems to have started then.
I tried re flashing a backup, which didn't help and I flashed franco kernel reading it gave good battery.
My last idea is simply reverting back to stock and see if it helps but before that I wanted to check some opinions or advice here.
PS I have already used BBS and its finding nothing wrong in wakelocks or use (except something called AudioOut2)
As I finish this im down to 66%, definitely not normal.
Any help is appreciated.

Did you at some point let it drain completely to 0% after updating to 4.2.2?
If nobody has any idea ill just go back to stock and report results.
Sent from my Nexus 7 using Tapatalk HD
Well if anybody has a similar issue or cares, going back to stock seems to have fixed the issue. Regardless I did some light testing on the battery. It shows marginal better perfomance on 4.2.2
By switching Kernel there was no change it seems but then again the test only covered two activities perhaps with further comparissons better results would be gotten.
But long story short if anybody has this problem apparently going back to stock is the way to go.
I'll keep a careful eye on the battery and gauge on regular use and if it happens again have a better idea of what caused it.
Its a program that's running or not completely shutting down.
Torrent was my issue. Uninstalled rebooted and then reinstalled.
My battery life is good now.all day and still over 80%.

Well I have encountered a completely new problem lately.
In the last week this has happened 3-4 times. I leave it charging or simply on deep sleep for a while and when I try to turn it on it won't, I'm not sure if its shutting down since when I plugged it in (thinking battery had drained) not battery charging animation came up, instead I left the power button pressed and it came up with whatever charge it had.
Not sure if its a side effect of the original problem of the battery discharge or something to do with torrent clients as 3 of the total times it has happened I was downloading something and left it running.
Not sure what to do at this point since I find no info on this or it happening to anybody else. What I find are things like it not charging etc which really arent my issues.
I will avoid using torrents on it for a few days and see if it happens again, if it does I will seriously have to consider contacting Google or Asus since this device doesn't even have 90 days in my possession yet.
If anyone is following this (really just posting here to help anybody who finds the same problem and as a sort of journal) I found this post on the kernel im running thread
http://forum.xda-developers.com/showpost.php?p=38422891&postcount=4603
Somebody replied to that post stating its a 4.2.x problem
It could also be a kernel problem with torrents as further down the posts another person complains about the same happening when using a bittorrent client
I'll post with whatever I find out.
I've been having the same problem glad to see it isn't just me.

Hi Chaps, Since my upgrade to 4.2.2 I thought the battery life was great. It stayed at 100% for ages and when I was streaming music for a few of hours and the battery only went to 96%. Superb I thought..
But, yes there is a but. My N7 now shuts down when the battery is at 32% and I need to charge it to get it to reboot as it is well drained. Is it possible to zero the battery indicator or recalibrate it for an accurate reading? TATA R.

Battery calibration, which should be done rarely, is merely a matter of putting your device through one complete charge/discharge cycle. Don't waste your time with battery calibration apps, as they are 100% snake oil. Likewise, you can disregard any misinformation about wiping battery stats, as that has absolutely no bearing on battery charge indication.
Try unplugging your battery for a few minutes, and then plug it back in, ensuring that the connector is firmly seated.
Getting pissed off here. N7 shuts down at 42% now. WTF. Is this a 4.2.2 problem? If so how do I revert back to an earlier version?

I am seeing reduced battery life on 4.2.2...
I used to be able to go all day on a charge. Now I can't make it through the evening ...
I know that is subjective as I didn't indicate my prior usage compared to my current usage pattern.
But my perception is that battery life has degraded ...
As an aside, I noticed that an el-cheapo IKEA power strip didn't provide enough juice to keep the battery from draining further while using it when plugged in...
It plugged in at 20% and kept using the N7... awhile later I was in the mid-teens.
I don't use that power strip any longer....

Hi guys,
A couple of weeks ago, Note II informed me of an upgrade. I did a bit of googling and found out it was to fix some exonys bug. Seemed pretty important so I did the upgrade post haste.
At first the battery life was atrocious (like a 50% drop). The same thing happened with my old iPhone 4 but everything reverted to normal within a week. So, I though maybe things are new and Android will fix itself up after some time.
How wrong was I ? LOL. My phone gives me just a day's worth of battery life. Earlier it was a solid two days. Which was why I justified carrying this brick of a phone. It is pretty ridiculous to see the battery drop by 30% at times in three or four hours (despite zero use).
Any suggestions to improve or remove the pathetic firmware upgrade.
1. Use the nova launcer
2. Auto brightness with the slider dragged to 1/3rd
3. 3G always on
4. The battery screen shows screen taking 70% of the battery! I have the auto off timer set to 15s the minimum.
Any suggestions guys? I am frustrated with this phone post the update. Thinking of switching back to the iPhone as atleast it gave me a day's pf juice in a much pocketable format.:crying:

Honestly you can't do anything. In American english, you can't do nothing!
Turn 3G off, when you don't need it. Keep brightness at as low as possible.
That's all. 4.1.2 drains juice faster than 4.1.1, it's the truth, doesn't really matter if someone agrees or not.
You could go back to 4.1.1 ROM you know and depend on your luck for that Exynos issue. Otherwise give up on great battery backup and stay with 4.1.2, like I'm doing. Nowadays I don't even monitor how much battery backup/screen on time I'm getting, on 4.1.1 it was the opposite story however.
Hey, so should I just resign myself to a gimped battery? What really hurts is how awesome the battery was before.
Any word on when samsung would release a good update?

Download better battery stats to make sure there is no wake lock. I will advise despite my best efforts the battery life has plummeted when upgrading to 4.1.2. Stick to 4.1.1 for battery life. It still lasts much longer than an average handset saying that

After updating to 4.1.2 my battery runs down about 20% quicker overall I would say. 70% for your screen seems severe. Mine is always set to 50% auto and takes between 30 to 35% of the battery usage.

If you go back to 4.1.1.... Stock even....you'll have the same battery issue.
After about 2 weeks of having the 4.1.2 (the second update I received) on DBT my battery life one day just magically got better! I had been having terrible battery life (like 1 days worth) for 3 months, and now I get home every day from work with 50-70% battery. I charge it every night, regardless of the %. But it just magically got better. I'd say give it a go for a week or 2, and see if it helps. I don't know what happened with mine, but it looks like the software just "settled in" because I didn't install ANYTHING new, and in fact, I hadn't even uninstalled anything! It just got better after using it. Do a few battery pulls / restarts, too.
I went back to 4.1.2 last night and right now I'm at 50% charge, 17 hours standby time and 5 hours of screen time... I'd say my battery issue is fixed.. for now lol
I also must say that after a week or so of using 4.1.2 battery went much better overnight. I automatically turn on airplane mode during night, and on 4.1.1 I had like 1-2% drain overnight from full charge. After updrage to 4.1.2 it jumped to 10-20% !!! Now, it is down to like 4%, which is not that bad. Still have to see how it behaves during the day, I think it is not any better. Well, at least that standby drain is (much) better....

When will it come for the s4? Probably just a matter of time, but do you guys Really think this is realistic? A 50% increase seems astronomic to me. In the text above it says the playing time of angry birds almost got doubled

If you had even made the effort to read the article , you wouldn't be writing that. People like you will never make progress in anything because everything that requires thinking out of the box seems impossible to achieve if you start like that. The PowerXtend algorithms change the way how software and hardware interact and optimizes it. The battery life is already tremendously improved on the s5 which is a fact, so you don't have to start with talking about your friends cousins sister and so on.. This by the way doesn't require some extreme CPU throttling , and I honestly don't know why anyone should have a 100% CPU-usage while surfing on the Internet for example. That's what optimization is.

I fully agree with you. For internet browsing, the power is not needed by CPU, but by the WiFi/3G/LTE. And, most of battery capacity goes there in such case.
But, 100% CPU is needed to keep alive in the background you email, tweeter, facebook, google and samsung sync plus any other app you may have.
For example, using the NavXtend.The outcome is that my position jumps around when I'm turning or suddenly stopping/accelerating. This is caused by the redirection of part of GPS requests to loop which predicts my movement.
But, you are absolutely right, I did not read the article. Instead, I went to the manufacturer portal, where he clearly states that any savings may be "up to" something.
And, exactly as with NavXtend, I will TRY any solution instead of sending excited posts that someone wrote something somewhere.
