Welcome to the forums. Can you provide some screenshots of your battery stats, please?

Sorry but today I used my phone till it was dead and now I have charged it till 100% so the battery stats is empty

Do you use your phone a lot? The screen can typically be the highest drain on the battery.

 

[babin08]

Yeah I do use my phone much

Maybe turning the brightness down a bit?

Doesn't work for me.I always keep it in the lowest

My last 1% stands for a very long time.Before it took me almost 2 hours to finish the battery.For now see the screenshot.
