XPS 13 : how long keep your battery ?
Hi all,
Since I upgraded the BIOS for my XPS 13 9360, I saw my battery becoming very weak.
My computer is very new and i can't go more than 4 hours and 30 minutes with a full charge.
How can I change this ?
I do mails, webs, texts, no pictures, no games.
Thank you all!
