Help Lenovo A6000 overheating, battery draining fast

[PeFe]

Hello,

it is a day since my phone started overheating (not the battery, but the CPU), the battery is draining insanely fast (see plot in screenshot attached) and it seems that something is just milking the CPU for its whole processing power and that something might be a process called dex2oat. You can see it in a process list in the screenshot, which I had to take with another phone, because I can't send it, nor download it from Lenovo...it's just generally misbehaving now. Also, could it be a virus? thank you

From your snapshot it looks like Prebudit is sucking on the battery really well... What is it???... Kill it now and let us know what happens...

No, that is just a Slovak translation of...I think it's a "stay awake" service or process or something

I'm gonna do the factory reset, since currently it won't even connect to USB, so bye file transfer and byebye USB debugging
