hello good thing is I want to know how long it takes them to charge you because there are nights when I put it to charge to 100% and lasts much awake and still 100% and go several days when despiesto already in 94%.
I shut down everything you spend battery at night and close all apps in the background

It lasted seven days and only drop to 94% how did you do it?

no hard seven days was only one night but sometimes awake and todabia has 100%.
And I would like to know why are percentage changes every night if I disconnect it when it reaches 100%.
And sorry for my English I'm using a translator I am from mexico
