Battery usage showing flat & in negative values

[RohitTech]

Strangely since 2 days whenever I enable stamina mode it use to get enabled via widget but on status bar the +plus symbol only appears after dropping to specific battery levels.

Then I went to check battery levels I was shocked to find Battery usage showing flat & in negative values and everything to zero like wifi, network signal etc.

I have booted in safe mode and its doing same.

I have reseted the service of Stamina mode by clearing cache etc. but have kept my phone for charging before rebooting it.

But how to resolve this issue about battery usage??? I want it back to be recorrected as it was before.

Do I need to reset or clear any more services??

I'm on Lollipop 5.1.1 23.4.A.0.546

This looks quite strange, may you try suggestions mentioned in this post?

I think a phone repair via PC Companion would resolve that, but try the simpler solutions first.

Well I went to that page but the instructions are unclear.

It say...

On Xperias with built in / embedded battery

The way to force shutdown varies with phone. To find the correct way go to Support > select your phone > Select "User Guide"

So theres no Support or such option in my phone so where m I suppsoe to go???

Ok I guess what happened is yesterday I was working on a app and for that I forwarded the date to Year 2020.

I think this has caused the issue.

But then the date was recorrected to normal after 5 min. And yesterday I also didnt charge my phone.

Now if this is an issue its a major bug then. Coz simply forwarding phone time must not mess with battery data right???

Not sure about that, because you charge at time x, then forward phone's time to x+100. Battery consumption is a formula based mainly on time, I think you know what caused the issue and this should be fixed when you charge your phone on the corrected timing.

charge your phone on the corrected timing.??? So want me to wait till year 2020???

There must be some other way out for sure without resetting or formatting the phone.

Else its a major bug in android.
