Hello.
Today I realice that my iPad battery % is differente from the remaining % I can get from any iPad info or battery info App. The difference is 5%. When the tradicional iPad battery meter says 89% the apps that monitor the battery says 85%.
Can any body please help me?
I think 3erd party apps can only show values like 90,85,80 and not 90,89,88 ... Is this right?
Thank you.

It depends entire on what 3rd party % app i use.

i want to help you but seems i am not able to
because i am not very familiar with ipad

Correct, most 3rd party battery monitoring apps go in 5% increments/decrements.

I have not found a battery app yet that does not measure in 5% increments. The ones that warn you about this in the app description seem to be indicating that it is a limitation placed on them by iOS.

I don't know if this is going to answer your question about the battery indicator but for charging your iPad, I suggest you purchase a really good battery. I just bought mine from NewTrent called the imp880E and it's incredible! I've bought other batteries from them before but this newest one charges my iPad by 100%! Plus they have a really good return policy.

Don't forget to completely drain the battery of your iPad once a Month.
This is required for the battery-meter to be readjusted, as otherwise it will begin giving false readings. This might also explain why there are differences.
