High CPU usage when phone idles

[TorSuneson]

I have a Z3+ that one night started consuming alot of CPU, I have a screenshot of when it happend because Its possible to see when the drain starts. See the knee at roughly 1 A.M. ( then I was a sleep )

I have used a busy box  to see that its not the battery that went bad, its a stedy consumption of ~8.0/8.0/8.0 in the CPU usage.

So I go the recomendation to put the phone safemode to rule out any third party applications. 

This is phone in failsafe mode, sitting at a desk doing nothing. Still CPU consumtion is really high. 

Now I have just about uninstalled every app I got on the phone and still no resolution to the problem. 

Using android 6.0.1, Kernel version 3.10.84-perf-g0802f10

Any one that does have any idea to fix this?

Hello @TorSuneson, welcome to the community!

I'm sorry to hear your phone is experiencing this behavior.

First of all I would recommend that you try and boot your device without any SIM- or SD-card inserted. Try running it for a few hours and see if it is showing the same behavior. 

If the behavior persists in safe mode, I would recommend that you try and perform a software repair on your device as the screen shots you've uploaded doesn't show what is causing your battery to discharge at such a high rate. The software repair is to rule out that there is anything with the software causing this behavior. I would advice that you try using  your device for a few hours before you restore any backups or data in order to rule out corrupt data being behind this. 

Let me know if there is any change!

If you don't need LTE network try switching band modes
