All task killers are worse for battery life... which rom are you using now?
Battery drain so fast
- Thread starter Bilmoussaoui
- Start date
I have the same problem in 4.4.2 but the battery does not last one day in TCL 4.2.2 the battery lasted 2 ~ 3 days
sorry my english

AFAICS, the problem in my 9192 with battery drain are kernel wakelocks.
BUT it's only happen when the wifi is on.
At this time, I can see horrible number of "mmc1_detect" and "mmc0_detect" wakelocks. Deep sleep is only 73% then, and battery drain ~2,7%/h.
And, if I turn the wifi off, everythings return to normal: deep sleep is 96% or more and battery 0,5% per hour or less, with both simcards inserted and data on in 3G!
It happens on all AOSP based ROMs (CM, CARBON, MoKee) but on stock or "stockromlite v1.3" all is good.
So I presume, it's a KK kernel bug...

This is an old topic. The problem of S4 mini battery drain is the governor on the default kernel, which is performance. There's some trick and long-way about method on fix it, but to get to the bottom of the problem is the flash a custom kernel.11
rooting doesn't especially trip knox depending on the method. but a custom recovery will. if knox is tripped you warranty of the phone could be void1- Rooting has nothing to do with custom recovery.
- Install a custom recovery required you to use ODIN
- Flash anything with ODIN will trigger KNOX
- You can check if your phone has KNOX in download mode, if it has somehting like KNOX COUNTER 0x0. If it shows 0x1 which means it has been tripped, and that means warranty void. If you see nothing like that that means yoy have no KNOW = go wild.1
User a kernel tweak (such as this:https://play.google.com/store/apps/details?id=com.dsht.kerneltweaker) program and change you CPU governor to ondemand, interactive or other more power friendly ones.
You can also get better battery stat to see what is causing the power drain.
