iPad Air 2 charging problems
My Ipad Air 2 (64gb, wifi & cellular, iOS 10.2.1) won’t charge when connected to a wall adapter (original Apple charger, cable and adapter too, my iphone charging and syncing perfectly with these) or sync with my MacBook Pro.
When the battery is fully drained charging start to 2% when it boots the OS and then stops the charging.
I tried to force restart (home and sleep/wake button), nothing changed but when I didn't release the buttons after the first restart, the screen turned on with the sign "connect to iTunes”, a few minutes later the iPad restarted automatically and it was at a higher battery percentage than before, so I think when the last screen was active, it was charging at the background. So I did this process again and again, and the battery percentage was higher at every restart. Once when I did this restart method I left the iPad to charge with the “connect to iTunes” screen and after the next restart the charging didn’t stop till the battery percentage was 98%.
Another surprise when I connected the iPad to my MacBook Pro when it was fully drained, the charging was started and at 2% the OS booted on the iPad and iTunes started to syncing my device. I made a backup save and then upgraded to iOS 11.2.6. checked the battery with Coconut Battery(145 loadcycles, 6975 mAh capacity, 95% health, good condition).
Nothing changed after that. The device won’t charge and sync when the iOS is running but if I restart when plugged in to my MacBook Pro it is syncing and charging, till 95% the charging icon is active next to the battery sign, after that the charging icon fades away (checked on iTunes too) but the charging doesn’t stop.
Any good ideas? I don’t know how can I solve this problem. I called the local Apple Authorized Service Provider (Budapest, Hungary) they said that "This is a fault of the logic board can’t repair only change the full part"...
Es esta una buena pregunta?
