    Hello.
    First of all, sorry for my English.
    I bought S4 mini, used, in a very good condition. Everything works just fine, but my battery is very bad.
    After 100% charging, it drops to 0% in just 6-7h.
    After some research, I found out that my Android OS uses 79%-85%, sometimes even 91% ??
    The phone is always awake even if the screen is off, wakelock detector shows that some " TimaService " is keeping him awake, I cannot find that service to turn it off...
    I tried, factory reset, hard reset, nothing worked. I have 4.4.2 KitKat Firmware.
    What should I do?

    Welcome to Android Central! I've seen other posts about this. You could try reinstalling the firmware using Samsung Kies.
