Why does the battery level going down, when there is no battery installed? Answered
I have a 7" tablet, which battery got a damage, and stopped working. I replaced the battery with an USB cable, and plug it into a 850maH phone charger.
First of all, the tablet keep saying that there is an over voltage in the battery. I assume its because I have 5V instead of 3.7V. I don't know if i could cause some problems in the future or not.
Second: if I connect some other mobile charger like a bigger one, the screen stops responding, or goes crazy. I experienced something like this when charging an old phone. Possible causes?
Third: the most interesting thing is, that my tablet says its battery is draining. It is mostly constant, faster when screen is on, even though there is no battery in it...
If you guys have an answer to any of these questions, I would really appreciate your help.
Thank you in advance,
