I'm an old iphone user, but only this week I bought my first iPad. I got the iPad 4th generation and I have a few doubts. 1 - It came showing 93% of battery, but it was draining very fast. I used a lot (but not discharged it completely) and them charged a few times, and it continued to drain very fast the battery life. Yesterday I decided to complete a full battery cycle. I used the iPad until it turned off, them plugged in the charger and let it charge throughout the night. Today I picked it with 100% but the battery continues to drain with unusual speed. Is there any way to "correctly charge" the battery? Because I can't see how it will stand the announced 10 hours of usage. 2 - The iPad is heating a lot. Is it normal?
