Note 2: Battery Drain after 4.3 update

Re: Battery Drain after 4.3 update

Ever since updating my Galaxy Note 2 to 4.3 my battery has been draining very quickly as well. When I left home this morning at 8 am I was at 100%. It's now 11:30 and I am at 22%. WTH? I never used to have to charge my phone until around 8 pm in the evening because it would stay charged all day. Now I have to keep a charger with me. I have not made any other changes to the phone so I don't know what's going on.

Do I need to take the phone to Sprint so they can look at it?

Re: Battery Drain after 4.3 update

Guys,

I noticed after the update that location services were turned off. After turning that off, my phone is back to normal. *Remember to turn off GPS tag in the camera as well. Hope this helps!

Re: Battery Drain after 4.3 update

Anyone that is having issues after doing the update, that didn't do a factory reset after the update, should factory reset.

I had a couple things not working, like the voice command "reject" for incoming calls, but "answer" would work, wakelocks were crazy , way too many and my battery was eating up.

I did a reset, "reject" works, wakelocks are better than normal and I just spent 7.5 hours online, constantly, intentionally, battery started at 90% and it's just now down to 15% and I'm charging.

I have always done a factory reset after every firmware upgrade. It just seems to correct a lot of things.

I would do a reset and if it is still a problem, install this app and it will tell you which app is using up your battery.

Re: Battery Drain after 4.3 update

Same issue here. i updated OTA (India) to 4.3 about 15 days ago. Battery started draining from day 1. Used to last about 2 days, now mere 15 hrs (from 100% to 3%). I uninstalled a lot of apps and turned off many features/location services (Google is the culprit), but still no improvement. Did a factory reset a week ago and reupdated as someone suggested. Nada. Then, yesterday i updated with kies 3 as kies 2.6 does not support the phone now. still nothing. I'm attaching a pic of battery status of last 15 hrs of normal usage (calls, whatsapp etc). Please help. Should i root?:-\

Re: Battery Drain after 4.3 update

I'm not sure what your issue is actually. 15 hours of battery is good unless you don't even touch the phone once during that 15 hours.

I would install this app from the play store and get a detailed view of what your phone is doing.

Re: Battery Drain after 4.3 update

I am also facing battery drain issue, more over Knox is not installed on my phone, where as I am facing issues on charging also, using the original charger & cable, but it takes more than 10hrs to charge the phone & some times it don't charge when charger is connected...

Strange thing is, battery is draining like hell, I keep it 100% on night while sleeping & in morning its hardly 15-20% left, with no application running....

Consuming the battery while browsing on chrome (even on reading articles), I don't know what is wrong with 4.3 update, and now I am stucked, not getting any option to even downgrade it to 4.1

can anyone help.

Re: Battery Drain after 4.3 update

Apologies I have posted this in another thread but is the same issues - does anyone have any answers yet:
I also have been having horrendous issues since the update. I have sent this (copy below) email to Samsung support. Does anybody else have any suggestions re my app data restoration issues and not only did I supposedly back up with KIES I also used a third party program called Clean Master back up. That too only backed up the app installation files and none of the actual game save/progress data which is massively annoying.
I also installed and uninstalled KNOX which had no effect and force stopping the various KNOX bits in Application Manager has had no effect either. Some restart anyway and you can't Disable the bl**dy things!

Any help would be much appreciated.
Copy of my email to Samsung:
Can someone please explain to me why following the 4.3 update from 4.1.2 on my Note 2 I have had nothing but problems..and it appears to be widespread amongst other users!!

Before I updated I used KIES to perform a full back up including calendar, applications, misc. files, settings, preferences etc. Once the update was complete I performed ANOTHER back up.

As with many other users I found the battery drain dreadful - even with data switched off, apps stopped - I tried many troubleshooting methods to no avail. So, as Samsung and other forums suggested I performed a factory reset as this was suggested and supposedly cleared the high battery drain and RAM usage.

However not only has this FAILED - my battery drained 30% overnight with all data, gps, screen etc switched off and to make matters worse and extremely annoying is that the back ups I had taken as described above also FAILED in that they did NOT restore my calendar, NOT restore the app DATA only the app installation files and NOT the actual saved game data, which means ALL my apps have been reset and I cannot find a way to get them back!! Plus other promotional apps I had which where ad-free on the day they were installed are now the ad-supported once re-installed from both the Back up and Play store.

I am bitterly disappointed and would like an explanation on how I can restore my lost game/calendar data and resolve this dreadful battery drain.

Re: Battery Drain after 4.3 update

Yeah..I have an answer, see above. Do a reset, if that doesn't work, the app that will tell you what is draining your battery.

Re: Battery Drain after 4.3 update

Hi Kelly
Thank you for your suggestion. I have installed wake lock and will conduct test. However it doesn't address why this awful drain is happening POST 4.3 update. I was perfectly happy getting 2 days out of a full charge on 4.1.2 I have actually uninstalled various apps since 4.3 to help reduce load etc so in fact I am running less on my phone (other than any new processes brought in by update and no I am not running Knox) than before. Wake lock may help identify what is causing the issue brought about solely by a supposed update.
I also remain troubled by the inability to restore app saved data. Cheers.

The I had atleast 85% wakelock which started heppening some days back and the culprit was Google Play Service.. Nothing helped.

There has been an update released :N7100XXUEMKD 3-4 days back.

I just did factory reset -> installed the upgrade, then again factory reset.

The wakelocks are gone.and my battery life is like 27 hrs approx with:
Moderate internet use
WIFI- ON all the time
MOBILE DATA: ON all the time
Brightness: Auto
Smartstay - ON

Did you reset first? I never do an update without a reset after as many don't. Many of us have found there will be various problems after an update and most times a reset clears them up..

Most times just a reset after the update corrects it all, not always, but most of the time.

I don't remember..do you have an extended battery? I'm not sure what is wrong with 15 hour battery usage..that's a good battery usage.

Post your battery screen and the detail screen of the battery graph.

Re: Battery Drain after 4.3 update

Hi Kelly Yes I'd read the recommendation to do a factory reset as per my post and it is that which is the culprit for wiping my app data. I've reset and restored as much as I can following the 4.3 update but still poor battery life (another 40% drop with minimal/average use in 4-5 hours) and apps without data

Can you post some battery screenshots? The graph battery page and the detail also and the display info?

Actually I forgot to mention that I tried other things as well.
This was my last resort, and i posted this coz it worked for me not once but thrice.

So I would strongly encourage others to consider this option as promising, if other means don't fix your problem

Re: Battery Drain after 4.3 update

All I did was follow this sequence Factory reset->firmware upgrade->factory reset before use.

Can you elaborate how did you do this? which software did you used for the "factory reset before use"? Because such opstion isn't on my note at all except for Settings>Accounts>BackUp and Restore>Factory Settings!!
