Have you ever dropped your phone in water at all? Maybe you have a bad battery, because those battery stats are worse than even running complete stock. Post all of your info, Hboot, radio, kernel, etc. And hopefully we can help you out with your issue.
Hboot: .92
Kernel: Tinys gingersense 11/19
Radio : 2.15.00.0808
And no never dropped it in water

that sounds unreasonably bad. I'm on Joelz Prime, too, but I think only up to R40. I doubt there's anything in those last few commits to cause this, though. Try re-flashing, wiping battery stats, and give it a few cycles then reevaluate things. What apps are shown in the "Battery Use" settings menu?
Failing that, could be some hardware issue causing a short or something that's draining things... There have been cases where water or other damage can kill the battery life. Good luck.
I reflashed 3 times and still horrible battery life .
Water never got on my phone .
And in battery use nothing major is running . Except like display, os ect.

I have 3 batterys and they all work the same
Sent from my HTC Droid Incredible using xda premium
I've been using Joelz XL 4.0r42 for a few days now and I can say battery life is a little worse than 3.9, but not down to 3 hours. I change overnight, disconnect at 7:30am and charge again at 11pm. But that is with 5 or less calls, 10 texts, and emailing only.
Could email be on push? Did you try the power settings under tweak? I have tried normal and performance and see no difference. Someone said that one of the widgets was killing performance in an earlier post (in the PrimeXL thread), maybe the same widget is killing the battery too?

I dunno, then... try leaving it in Airplane mode for a little while, to see if it's something radio, etc.-related. otherwise, something's probably wrong with a hardware element somewhere along the line. I hope you're able to solve the issue.

I've read a tip to do this:
-get battery full before installing ROM
-wipe battery stats and flash new ROM
-Let it settle in, set it up a bit, then fill up the battery again
-go back to Recovery and wipe stats again, while it's full.
I'm not clear on the logic behind it - could be somebody's superstitions - but it's not a difficult step to take in the hopes that it does some good.
there are others who said they run a script at shut down to wipe them every time the phone reboots. Seems like everyone has their little tricks.
This may be a long shot, but my guess would be some kind of internal hardware issue. Maybe there's a problem with the micro USB port and it's not actually fully charging the batteries.
Shut the phone off and charge it till the lights green. And if you want any kind of battery life, sense is not the rom to be on. Especially 3.5.

There are tons of things that effect battery life and tons of things to save battery. Underclocking, undervolting, lengthning time between syncs, increasing wifi scan interval, lowering screen brightness, keeping running services to a minimum. However even with your phone set to max performance settings with all the bells and whistles on, you should still get more than 3 hours out of a charge. If multipul batteries give the same results, i would say its hardware related, or your charger is messed up and its not charging or messing up the batteries.
I wiped battery stats andseeing where that leads me
Right now when I wiped it and I played modern combat 2 for an hour and my percent is 61
So ill say imma get 2 hours out of my batt?

Having some strange battery issues....
My battery was at 24%.. I plugged it in to charge and left if for an hour and it would not move past 24%. Unplugged it, plugged it back in, left it... same 24%.
I gave the phone a restart, and when it booted, it now read 65%.
Last week, I had been noticing bad battery life, so I did the battery calibration talked about here ( http://forum.xda-developers.com/showpost.php?p=23203126&postcount=9 ) and then cleared my battery stats...
Battery life definatly improved, but, now I had this issue today.
Any idea what could be causing it?
Oh yeah:
Rooted Phone, running Myn's Warm TwoPointTwo RLS 5. Kernel: 2.6.32.17 [email protected] #2
I'm glad to hear calibrating your battery yielded improved battery life for you. I've experienced the same thing in the past with other ROMs, but I haven't while using my current ROM (Nitrous ROM). I may be mistaken in assuming it's because of some setting in the ROM, but it's just something I noticed. Or possibly it's because I'm using the stock kernel with this ROM? I'd be interested in hearing if anyone definitively knows what causes the battery misreadings too.
I read somewhere in the forums(cant remember where exactly) that when flashing roms, its a good idea to re-calibrate your battery after every flash....I've been doing that since I read it and seems to work as far as I can tell

Your battery could be going bad, but if its just a reading error, then it could just be the ROM you are running.

You are correct it was found by members of googles development team to be unnecessary and could possibly do more harm than good in terms of the phone using the battery properly, newer phones like the et4g come stock with trickle charge kernels(read SBC) to try and discourage ppl from wiping them by giving them a more accurate reading in the 90-100 range

I always try to calibrate battery (on full charge) after flashing a new rom. Search the market, Battery Calibration is free.
So, to rule out the phone itself/rom/etc I swapped batteries with the wife for a couple days. She has the same phone, same ROM, Same Kernel, same everything...
Anyways, long story short, the battery acts the same way in her phone as it did in mine, while her battery works perfect in my phone just as it did in hers.
So the battery is definatly toast... I've already got a brand new OEM battery on its way to me...
Figured i'd come give an update. Thanks all!
(Oh yeah, to vel7wil and the others, I DID recalibrate the battery, as I mentioned in my initial post. So, be it unneccessary or not, it didnt help me any in this case lol!)

i'm using this ROM and it automatically shutdowns my Nexus 7 when the battery is below 20%, anyway to fix this ??
P/s: some people say that because it did not calibrate my battery after flashing the ROM, but i wiped everything, included battery stats, is that ok ? or i have to calibrate it ?
You can't calibrate the battery. Anyone who told you to do so deserves to be slapped with a pimp hand. Likewise, never waste your time sipping battery stats. It is in no way, shape, or form going to affect battery life or the battery fuel gauge.
Try a factory reset. If that doesn't correct the problem, try the stock rom. If you still have the problem, it's defective hardware.

Thank you so much :good:
@ but actually when i change to another rom, this did not happen, so i think it is a software problem
I have had this phone for about 2 months now and everything has been exceptional with the phone. Have seen people complain about the battery life, however it has been really good as far as my experience is concerned. However since a week I have seen the battery screwing up a lot... A LOT.
I always used to charge my phone daily in night. Plug it in..set an alarm of 3.5 hours (yes it takes 3.5 hours to fully charge from less than 10% stage) wake up..turn charging off..sleep back. Okay, some of u might think it is stupid but can’t risk of leaving it on charge the whole night and burn my phone. Anyhow, so, since a week what I do is I charge my phone whenever I want (read it on a few thread and articles)..be it 50%... 80% or even 92%. I just make sure its 100% whenever I leave home.
But something weird has started happening... The battery percentage keeps on changing.. For instance:
when I unplug it..its 100%.. within minutes of usage it drops to 99..then 98.. then 97 and suddenly it rises back to 100%. (Pics attached)
Sometimes when its on charge and I come to check SMSz and reply them.. battery % suddenly drops.. e.g: if its at 99%... it will suddenly change to 96% in a second and in a minute goes back to 99% .. so on and so forth. And sometimes even when its charging..if it is at 80%, it will suddenly shoot up to 100%. The percentage doesn’t change even after a reboot. Weird, isn’t it?
Now the most weird issue, since yesterday the battery life and dropped to 50% less. I used to get 4 hours OST and now I hardly get 2 hours. During night, the battery used to drop 2% in about 6 to 7 hours and yesterday it dropped 15%. There was this one time when it dropped 9% in 6.5 hours (pics attached). Tried seeing through Wale Lock Detector but there were no Awakes during deep sleep. Too weird :s
I don’t really know where did I phuck up as I haven’t installed any shaddy apps or something. Please advice.
My phone info:
All stock. No root (and not looking). No custom Roms whatsoever.
TL;DR... Battery acts weirdly. Shows inconsistent percentages. Suddenly shoots up. Suddenly Drops. And now the On Screen Time has reduced 50%.
It sounds like it's nothing more than a bug.

Thanks for ur reply. How to figure it out? And measures should be taken? Any suggestions?
this has really kept me worried since a few days.
This is "normal" for the N4, and the most/all of them do it. Unreliable drivers, or a hardware fault, not sure.
Here are other threads about the various battery bugs, but there are many more:

I know I searched many threads before posting and mostly had the Shooting up issue only, when charging.
Anyhow, this normal behavior has reduced my battery life a lot.. which I am not liking .. What to do?

Both my N4's (different H/W revisions) have been doing the 100 to 98 to 100 thing as well since new. Battery life is still excellent for me. An RMA would probably do the same.
Happens with my nexus 4 too. But this hasn't reduced my battery life at all...

You're pretty much stuck with that phone as you only have 15 days to RMA a device, your only option would be to send it into LG for a repair. My battery has acted up like this once so I stopped using the stock charger and it hasn't happened since.

Rebooting might help. Could also be an app that updated that now doesn't play nice. You could try a factory reset just to clear out some crap but I'd back everything up just in case first. Not sure if a factory reset deletes all your user data in memory or not. I only did it once right after I got the phone so can't remember. Hate to lose all your pictures, files, etc. that aren't backed up.

It's normal. The N4 isn't great about showing the exact battery life. In fact, what you see isn't the true percentage, it's an estimation. Don't worry too much about it!

This is a question I can't answer along with any facts. I tried disabling it for 2 days and I noticed the OST reduced from 4 hours to 3.xx hours. May its placebo or something but then I enabled it...thinking if it's not doing any good then it's not doing any harm either.

Hmmm, I didn't know that. But why is that? Any apps or something to show the exact battery percentage left?
Happens to me once in awhile. Do a quick reboot, and if that fixes it, I would not worry too much.
Hmmm..
Yesterday when I woke up in morning.. the battery lost 2% only in 6 hours. I felt SOOOO relieved that my "good battery" is back. But who knew what was to come... today I woke up after 7 hours and the battery lost 15% .
My usage is always the same. I force close all the apps I use daily and turn wifi etc all off. So i doubt if its any app.
Kitkat killed battery life. Used to be great, now it sucks.

KitKat didn't kill battery life. Mine is about the same as it was before KitKat. In about 99.999% of the time an app is to blame. I have a simple but arduous method to find the app that's killing your battery.
I agree the battery has taken a hit. I used to ave about 9hrs of screen on time, now about 6hrs. I also have the chromecast issue. Strange thing is that sometimes the screen doesnt even show up In the battery stats. Sometimes the usage time doesnt change when it shows in battery stats. I am stock, 32gb white US model updated with Kies. I have done many factory resets. I have tried it for 2 days without installing any apps or disabling any samsung bloat, with no change in the tablest behavior.

Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.
I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).
Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)
Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Yeah, I am used to android taking a bit to settle in. After my note 3 updated, it seems like it took a month to get back to my "normal". I hope the tablet does too, just frustrating in the mean time
Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.
I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.

Then not everyone would then mention that it is not change or improved (in stand-by).
No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.
4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.
I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.
The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.
You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.
My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.
So I say kk is good or better then jellybean

I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!
I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.
If it's a bad app I can find it. It worked flawlessly before the upgrade.
