Note 8 September Update Battery Drain

[Nexian]

Looks like this is bad update! After the September Update Battery backup has dropped drastically easily by 2-3 hours!! Dalvik cache clean did not work much, usually does.

Hope you fix it. Has made the phone laggy as well on the UI front.

Another issue is fast charging times have decreased. Seems to be charging like a normal charge.

flash your same firmware from service center...it's happening because of skip files during your last firmware update

I faced same problem in my s9..I just flashed firmware from service center...now my device working fantastic

No difference. They pretty much do the same using a PC software tool. Makes no difference. Luckily your issue is fixed.

but instead of downloading through own network..just do flash..there is much more deference...because sometimes if network is slow that can skip important files and cause battery drain, camera fault, device flickering like issue...once go to them I think your problem will be solved

Won't make a difference, android update is delivered as a zip file on OTA which is extracted on the device and then installed. That's why you see a message" extracting and installing ", so there is no chance of any file missing over OTA.

Just Google Samsung Kies and download software on laptop / desktop and follow the instructions.

it's possible by Odin v.3.0. or best way to go Samsung service center...another thing Samsung allaways prefer to flash firmware by them instead of downloading through your device network or wifi...it's recommended and actual procedure

best way to reinstall firmware is flash via Odin.. i usually install firmware via odin downloaded from sammobile.com..
no need to visit service centre again and again..
