    Welcome. I have a problem with the battery. After charging to 100% and disconnected from the wall, looking over web, the level immediately drops to 94%. Later, already is normal. What to do? Sorry for my english.

    This seems to be normal if I understand what you mean.

    Here is an explanation for a laptop with a similar discussion:
    I just turned on another device that was plugged in over night. like you said it immediately dropped to 94%. I then plugged it back in and it changed to 94% charging.
    I believe they do this so the battery is not charging at 100% all the time which can shorten the life of lithium ion batteries. once it drops below 95% then it will charge back to 100% then stop.

    At least once a month you should let the battery fully discharge or go down really low which will help your battery life and keep the battery estimate calibrated.

    Make sense?
