I had problem updating to 5.26 from 5.19 as my phone was really slow. I had to do clean install and now my phone drains battery as hell. :/ calendar force closes also

I have really bad UI and google now lag. Other apps work ok. A bit slower than usual but without noticable lag. I flashed .19 > .24 > .26 with dalvik/cache wipe
