Points battery performance on xperia x

[Import]

I'm not a heavy user but I'm lucky to great 8 hours battery life. I've turned off as much as I can see bug little impact. Stamina activated. Any ideas?

I have downloaded Xperia Companion on my computer, there is an option to completely reinstall the software on your phone but all of your data will be gone so you should made a backup before doing it. In my case It seems to have worked well , my battery life is quite good now compared to to my other phones ^^
