Battery life after 4.3 upgrade is bad.

Received OTA, installed the 4.3. But after the upgrade (about 48 hours), my battery life has taken a hammering.
Fully charged last night, did literally nothing so far. Just a few calls. No games or browsing at all. But battery is down to 50%. Stock and rooted.
I saw a few posts regarding same. But no definite answer. Any pointers what I should do here?
cheers!

Not sure why the CPU seems to be running at max frequency for such long time. I think that's causing the issue.

Nexus Battery issue aft 4.3 update
Need some help wrt my nexus 4. Charged the phone to 97% yday night and its currently at 52% aft 14hr 17min. The on screen time is 23mins. Battery stats shows that the phone was kept awake for 13hr 45min. WakeLock detector does not show any battery hogging apps as such. Any idea on how this can be fixed? The phone is on a stock 4.3 ROM.

Honestly i would re-flash the 4.3 images or something.
My phone has been 1 day 2h (or 26h) since last charge, with 2h screen on time and i have 57% battery left. Everything is stock (will flash franco.kernel soon-ish), but stock battery seems real good so far. I do not have loads of apps or anything like that yet - the phone is freshly installed with 4.3 and i only use whatsapp/hangouts/calls/sms/chrome/facebook/google now... no games or heavy use.

[Q] Updated to Kitkat 4.4, strange battery activity

Hello all. Been lurking on these forums for a while now and decided to register. Some very useful information here!
So I've got a rooted Nexus 4 and I went from stock 4.3 to 4.4 using the factory image from Google (did the full data wipe during the install). I updated the firmware last night and left it plugged in overnight so everything could download and sync. I also have the new Google Launcher installed.
This afternoon, I noticed the battery level drop from around 75% to 50% and then down to 16% in the space of a couple of hours without much use. Just replying to the odd Whatsapp or Hangouts message.
So I plugged it in, and decided to reboot after reading some comments here. And the battery went from 19% to 43% immediately after the reboot.
Is this because the firmware is fresh and it's still "settling in" or is there something else going on?

it seems like battery is not calibrated yet... it happened to me too...

You can try using the battery calibration app from the Play Store: h t t p s : / / play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en_GB (still can't post links). Just charge your phone up to 100%, open the battery calibration app, press the calibration button and disconnect your charger. It is recommended to let the battery fully discharge after this procedure.

I read that it takes a while for the firmware to settle in (on new phones at least) so I'll give it a few more days before I get some apps that mess around with calibration.
Thanks for the reply though, good to know I didn't screw up something with the flash.

Battery-life Issues with N4 after 4.4KitKat

I have an LGE Nexus 4 and I just got the 4.4 update a few days ago. I love the update so far, but one thing that really irritates me is:
Battery life! Ever since updating to 4.4, Exchange services is using up more battery than my screen! Other power hungry apps since the update are: Mediaserver, and Android System. (I'm running Nova Launche Prime, that's probably responsible for the android system usage.
I used to come home from school at 5PM with around 35-40% Battery. It's currently 12:45PM and i'm already at 65% :S. Anybody with tops and tricks to help me conserve battery life please do share with my self and the community!
thanks world ( ::cyclops:

I don't think you've provided enough information for us to really tell you. Try getting BetterBatteryStats and then check for yourself what's going on. Sven has fixed it to work on 4.4.

I've experienced the battery to be affected negatively on 4.4 as-well.
For now i turned off the voice command [ok google] which seem to help a bit but still not as good as 4.3.

ITs location services... turn it off and see how much better battery life you get or use device only then check your google services useage

Exchange Push is the issue
I have found that changing my Exchange settings from "Push" to check every X minutes has greatly improved my battery life. It seems to be much more inline with what I was used to with 4.3.
Hope this helps,

Well... I flashed 4.4.2 the other day and I saw my battery plummeting like mad... so naturally the first place I came to was XDA, and saw that a lot of people were having a big problem with battery life.
So I didn't do any battery pulls or anything like that on my N7100, but when the battery went from 85% down to 12% what I did was to turn on everything that I could in order to drain the battery... turned on Data, WiFi, turned off the battery saver etc. etc.
Down at about 6%, I got that alarm with the notification to plug in the charger but I just let it go.
After a while, the phone wouldn't turn on at all... nothing. Nada.
So I plugged in the charger and let it go.
I checked it in about 1.5 hours and it said 100% but the red charging LED was still on so I let it charge for about another half hour and finally the LED turned green.
I turned on the phone and held the power button until the screen flashed three times (About 15 seconds), and let it boot up.
I had 100% charge last nite @ 11:39, and right now on standby (12:45 the next day) I still have 95% on the battery.
Strangely enough, I didn't get one call on this phone all day... but when I don't answer my Note 2, people just try the other number on my iPhone 5s.
Granted, I never leave the WiFi on or data... but I have the stock ROM with all the crapware that it has... but I flashed that French version of KitKat off of that site that I won't mention (But it's that one that if you're not a paying member, it takes you half a day to download anything).
Pretty happy with KitKat stock rom so far, but that first few hours when when I saw my battery sucked dry before my eyes was pretty disconcerting.

brand new Galaxy S4 with battery problems and no help from Samsung!

Hi Everyone
I’ve bought yesterday a brand new Samsung Galaxy S4 here in Brazil (model GT-I9515L, it’s a Snapdragon 600 4G one), and I’m kinda worried about my battery life, which drags 1% every one or two minutes on simple Wi-Fi web browsing, I have been from 100% to zero in less than two hours, and I honestly don’t think that is normal.
I’ve tried a lot of things, I tried disabling some battery dragging features like the gestures, gps and etc, and still got terrible battery life
I’ve noticed that if I sit the phone down idle (screen off but powered on), it doesn’t seem to drag the battery much, when idle it seems equal to my Nexus 4 that I had previously, I'm starting to miss this phone more and more since I got the Galaxy.
The charging time is normal too, it goes from 0 to full in average time, two hours or so.
My phone is in 4.4.2 Kitkat (TouchWiz, unrooted) I’ve haven’t done anything to the phone other than apply OTA updates once it turned on the first time.
I’ve tried doing a factory reset via the settings menu (is this the same thing than reseting from recovery?) and not installing anything after but still got the battery drain problem.
Thinking that it was a faulty battery or phone I’ve brought it back to the store (an official Samsung Store here in Brazil), but they told me that my software was out-of-date, which I thought was strange because both the Software Update menu in phone settings and Kies found no updates to be applied.
I watched them as they put my phone in Odin mode and plugged my phone into one of the store’s computers, opened a program called “samsung master” in order to update my phone, but they couldn’t do it because my “Knox” was somehow messed up (which isn’t because it shows as 0x0) and told me to come back another day when the technician is there.
I became really frustrated with this, so far what I could diagnose was that somehow that my battery drain problem is a software one, and is solved by some kind of update that isn’t available by Kies, just in Samsung stores.
Can you guys give me any directions? I’m open to suggestions and if you guys need any other information, please tell me that I can post here, sorry for my English because I’m brazilian.

Drain almost always applies to when your screen is off. If you don't have drain while your screen is off, then it's perfectly normal.
2 hours of screen on time is perfectly normal. Your screen uses power, not much you can do about that.

When it's off, the batteery seems to last, but the performance is way worse than on my Nexus 4 (which is known for it's bad battery performance) when it comes to screen time, I've got near the double web browsing time on the nexus.
Your galaxy drains battery like this too? it seems insane to me. 2hours from 100% to zero without any of the features, brightness on the lowest level, only Wi-Fi on, I don't think every galaxy is like this.
When I brought them to the store, the salesperson told me that it had an update to be applied, but when I search for an update or put it into kies it shows me as up-to-date, do you guys know anything about that?

Here you can find the latest

Though I doubt a firmware upgrade would change it.
And yes, 2 to 2 1/2 hours screen on time is what I get.

Crashing, turn off and massive battery loss

So a few times now my note 4 has crashed (black screen) and turned off. When I turn back on the battery level has massively dropped (30-40% gone) yesterday went from about 40% to 0%. The 40% seemed accurate as using it not too much and usually about that percent at that time of day. Also noticed a few other things, when I connect my note to the pc it takes a while to start and stop charging and isn't being recognised by the pc (or the note isn't detecting it is connected to a pc - only charges)
Any ideas?

Try a different battery?
Are you rooted or custom rom?

Hi, not rooted and stock rom. Had an update yesterday which mentions better battery performance. maybe they fixed something. I'll give it a week. Have also contacted samsung. Not sure if battery is included in the 24 month warranty

I'm running stock 6.01 deodexed and rooted, It's happened to me a couple of time. Either its a samsung bug or the battery is just recalibrating itself. Probably the recalibration

That's good to know but worrying. Its really bad if it happens when I'm out. I think I have a good 10 hours of battery and then bam nothing. If I get anywhere with Samsung I'll post back
