Hey, sorry for not posting it on the ([NOOB FRIENDLY] Ask the question!) thread because I thought this might be a little too long winded.
So, I've bought this Note 4 (5.0.1) in Nov last year, battery life has been great, could last me 1 to 2day with a full charge with med usage.
But just recently (still on 5.0.1), I've noticed abnormal battery drain. When I unplugged my charger at 100% and when to bed (GPS/Wifi/Apps Closed), the next day it will not turn on. So I plugged it in and it says 0%. (Used to get only 5% drain to 95% over night)
So, the next night I put it in airplane mode and it still drains to 0%, what's more in the history details it says my Wifi is on the entire time even though it's not...
Fully charged it, unplugged and it would drain ~40% in around 4hrs standby with screen/wifi/gps off and would need a recharge almost twice a day... Even my 1800mAh One X doesn't even drain that much in idle.
Did a factory reset via stock recovery(Still unrooted), cleared cache partition, disabled sync all accounts, disabled searching for network even if wifi is off, formatted SD card, disabled unused services/apps/samsung's bloatware but it's still the same. (5.1.1 still not available on my device). Greenify can't find any apps to hibernate.
Highest power sapping was Android system using ~8% ( Was 23% before reset)
- Mine also has autofocus/blurry problem.
Edit - Oh, battery had ran to 0% thrice before these things happened.
> Should I send in back to Samsung for a replacement or try it with a new oem battery or root it with a custom rom/kernel? :confused: Thanks!
