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.
Factory reset and see if it still happens. A dirty flash can do weird stuff...

Ok, so I've had my SGN for little under a month for the first few weeks I had it I was getting great battery life, almost 6 hours screen time full day of battery etc.. Then I rooted it using one click root because I wanted some more access, since then battery life has seemingly been slowly getting worse. I have tried changing back to stock roms and custom roms, I've fully discharged the battery and charged while it is off a number of times but I'm down to 3 hours screen time and can't get a full day out off it anymore.
Is this something to do with the way I rooted, what can I do test and try and get back my battery life, this is the main reason I got this phone..
It's hard to say if it was the first update I installed/rooting or something wrong with the way I'm charging but it's certainly decreased even on a stock ROM without installing anything..
Anybody else encountered this?

I have the same "feeling" with my Note. I have installed System Panel to monitor usage but I can't find anything specific that seems to be sucking the power. But it certainly "feels" like my battery is draining faster than before.
It's probably as the phone gets older, you install more & more Apps. Some of these are probably working in the background sucking your battery.

Even with a clean stock rom, it doesn't seem as good as it was without root or any updates.. Wish I remembered what the phone came loaded with, I'd give that a go..

Try Rocket Rom v17 or latest XXLA1 firmware and your battery life will come back even better than before, just me
Same "feeling" here! I will try LA1 firmware....
So I'm currently sitting on 4.30 hours screen time, 15 hours uptime with 20% battery remaining.
Running la1 firmware and la3 modem, been using stock browser. Taking lots of photos with flash too, so I think this combo has rectified my issues but I know there's more potential as this is roughly the same stats I got on my dhd, although that was underclocked and tweaked to the clappers.
Faith is resetored in my device, hopefully it improves.
Hello!
Sorry I can't post this in the Paranoid Android thread yet. As a noob I can't post in that forum until I have 10 posts so I'm at a loss as to where I should post this.
Anyway, I just put the new 2.1799 PA ROM on my Nexus 7. Unfortunately, I seem to have a serious battery drain when the screen is on. I have read many posts where people claim to have easily achieved 6+ hours of active screen time per battery charge whereas I'm only getting 3-4 hours of active screen time per charge, almost all of it related to web surfing. I have a strong wifi signal and I keep my screen brightness around 20/30 range. I'm not sure if it's the ROM or if my battery is defective.
I have also read about a battery calibration app through a different thread. Is that necessary for the PA ROM? I didn't see anything in the tutorial mentioning a battery calibration.
Included are two pictures, although they aren't very indicative of my problem as my tablet was sitting in my backpack for most the day.
Please tell me I'm just being paranoid! Thank you for the help!

The battery recalibration is a myth, but there is also no harm in trying it.
according to the pics you have attached, there doesn't seem to be anything wrong.
Battery also drains faster if you have too many apps that have services running.
Ex: Facebook.
I know there is a battery warranty, but how bad does it have to be to get it replaced? My battery cannot reach the 9.5hrs of 720p video playback (with headphones in) as achieved by Asus. I can only get 8hrs. From normal usage, I am only able to get 6 hours.
The ROM has less to do with the battery than the kernel does.
I would say try flashing another kernel. The default cyanogenmod kernel that comes with Paranoid Android didn't give me very good battery life.
Franco kernel gives me excellent battery life. Other good ones for battery are Faux or Motley.

That is in the normal range i would say, Companies usually exaggerate.
As suggested try franco's kernel.
He has a free kernel flashing app on the play store.
My issue is with how the battery percentage is running down......
Charge the N7 to max and use it for a good 2 hours and the battery STILL reads 100%.
Even if I then shut down and reboot it still shows 100%, then all of a sudden it will start to drop very slowly at first until it gets to around 40% which it then shuts down and will not reboot, obviously void of any battery cells.
Clearly it's a calibration issue.
This is on a stock non-rooted machine.

Factory reset was the very first thing I tried when it started playing up.... I'm hoping when 4.1.2 rolls out it may clear it. If not then I'll have to look at doing a root and access the battery file to see if deleting may help.
Thing is a recharge should clear out the battery file stats and calibrate, which clearly it's not.
Apart from this the N7 is flawless so it's staying with me. Running hours is the same, just doesn't give an accurate reading of how the battery is running down.
It's not a big issue.... to be honest I'm more curious than annoyed.

You do realize that wiping batterystats.bin has absolutely nothing to do with the battery fuel gauge, right? It does not "calibrate" the battery or affect reported charge. The myth of wiping battery stats has long since been debunked by Google's Android engineers. The only info contained in the file is a list of apps that used battery since the last full charge.
The only other thing you could do besides a factory reset is see if 4.1.2 fixes it for you. If not, then it's definitely hardware causing the issue- the battery charge is likely being improperly read and reported by the battery itself.

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.

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....

Edit: After 50% battery drain in 8 hours of light/moderate use on wifi I'm going back to 4.1.1... I see no benefit of using 4.1.2.... The reason I bought my note 2 was to have a battery that will last me all day and this isn't cutting it.

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.

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.

Ok. Thanks for replies. Do u think Factory reset would do "anything"? better?

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.

According to that you should contact Google if you got it from the Play Store
Thank guys for your responses.
Kzoodroid, i regularly back up all my personal data.. Pictures.. Videos.. Music.. So thats not an issue. And all the games and apps r also backed up on my hard drive. So i guess factory reset wouldn't harm much in my case. Any idea how to factory reset N4?

Yeah, just go to settings, backup & reset and click factory reset.
By the way, I notice you use battery guru and I was wondering if that application really helps in saving/boosting battery life. Personally I like "Greenify". It's a great app.

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.
Just wanted to know if anyone else has problems with their Nexus 4 since the latest update?
So far, within 24 hours I have had to charge my phone twice fully.
What the hell is going on?
Thanks

What do the battery stats show?
Maybe this will solve your problem.

mine today started to get really hot.... it froze
upon reboot, it lost like 30% battery...
froze again in landscape mode
after a few reboots it continue to run super hot... like 65*
battery is draining even faster than what Ingress. uses
still occurs in safe mode
is the hardware going bad? i saw a few other folks having this also happen in the last week without ant solutions

Well then, since you replied to my post above... What did the battery stats show? Are Google services the problem?

i have had my current setup since i got the phone.. AOKP, Franco Kernel, undervolted -25mv, with like 215 total apps.... decent battery like, usually about 3 hrs SOT...
but yesterday was among weird to say the least.... Franco monitor will show my CPU was up to 170* at one point... but yet, my CPU usage on my monitor was with core 0-1 being less than half throtle while core 2-3 were offline... so i thought it was weird that my CPU would be so hot, yet not ON....it was so hot the phone would shutdown as soon as it got booted...
then my battery was not hot, but draining incredibly fast.... like from 88% to 19% in less than 2 hrs....
my battery usage pretty much displayed that it was the Screen consuming most of my battery.... i didnt notice GS being a problem, but im sure i would have noticed if it was
So far, i went ahead and factory reset, formatted /system /cache /data and dalvik... installed my rom again fresh.... its not acting up yet.... but for some reason i cant shake the fact its using battery much faster... i went earlier in my break from 94% to 87% in less than 10 minutes... thats not normal..maybe its just me..
so tonight i am going to reformat everything a couple times, install all fresh and see what happens before i restore everything back in the phone.

I'm with the same problem you're with. I did format everything, and the problem persists, can't really find the culprit on this.
I'm using PA 3.99 + FK, but I've tried with stock and cm, with stock kernels also.
Please let us know if you did solve the problem, and how did it, because this is becoming difficult to manage the use of this phone for me, having to carry the charger everywhere I go.

So battery life has been horrendous. It dies much faster and takes long to charge. My car charger no longer charges the phone... yet my Gnex and N7 FHD charges on that charger fine....
Qi charging works fine too (thats next to my bed)
So i called assurant, which sent me to Tmo, which sent me to Google (got it at play store) and they are sending me a new unit, since this one will be covered until manufacturer warranty for malfunction, not physical damage
Im sorry i will not have a resolution, i will revert back to stock and re lock it before i sent it back.... Hopefully i get a good one and not one with issues...
