I recalibrated the battery as Chris indicated to me and now working with Google Chrome and windows mail app the pc lasts 3.5 hours far from the 8 hours declared.
In my opinion the battery in any case has problems.
I contacted Banggood and asked for the replacement of the battery.
I also wanted to buy a powerbank for my Y13 but I am very confused. What are the features I need to look at?
Can you tell me which powerbanks work on amazon.it?
Thanks in advance to those who will help me.
