I have my iPad mini 4 updated to 9.2.1 and found a very weird charging behavior.
And I am pretty sure it was not present in 9.1 or 9.2
Before I leave my apartment this morning. I plug in the iPad to charger(not original one)
It has 80% battery left when I plugged it in. after 12 hours I back to my apartment and the iPad is charged to 88%.
Something's up. I pull my USB current meter, in case anyone don't know what it is.
It's like this.
-Then found out my iPad was charging at 0.01mah rate.
-I restart the iPad and charge again. Better but still at 0.2mah rate.
-Then I tried to turn off the ipad and charge. Boom! at 1.95A rate.
-While the cable still pluggin the iPad. I turn the iPad on.
-iOS load up. current dropped to 1A and not moving.
-Flip on the smart cover, screen turned on. Current rise to 1.5A
-Close the smart cover, screen turned off. Current drop back to 1A.
The charger is Anker 60W 5 port USB charger and the cable is Apple original one.
I don't have the original 10W iPad charger in apartment so I can't test if there's a difference now.
But I am pretty sure the Anker charger and cable is fine. Because when I plug my iPhone 6 and iPhone 6s Plus. They can charge up to 1.45A
Anyone experiencing this and know how to rectify the situation? Thanks!
