Default 4.4.4 bugs

I've updated my moto g to 4.4.4 yesterday. Since that screen on time doesn't show up or it shows inaccurate time. I played games for an hour but the screen on time shows something like 1 minute. The battery percentage is accurate but all the processes show inaccurate battery usage and Android OS has the highest usage. I've never had any problem when i had 4.4.2.I wiped the cache partition and did a factory reset. Still not fixed. Please help me. The phone is unrooted and the bootloader is locked.
