Hello,

For the past week my iPad Pro 9.7” no longer charges beyond 80%. It just says “not charging” despite being plugged in and not in use. If I unplug and then plug back in the iPad lights up and then immediately shows “not charging” message next to battery.

I have tried multiple cables connected to mains and USB. The charger & cable work fine with my iPhone.

I have restarted and hard rebooted numerous times as well as repeatedly unplugging and plugging back in.

According to coconut battery, the battery is in good health with about 300 cycles.

I have followed the tips & instruction on the internet with no luck.

Any help or suggestions would be much appreciated.

Many thanks!

Have you used that charger successfully with your iPad in the past? I only see the “not charging” message when the charger only delivers 500mA @ 5VDC. You’ll need a charger that can output at least 1A to charge your iPad.

Thanks for the reply.

Yes, it is the original apple charger that came with this iPad and has been working fine prior to this issue.

The same charger & cable also works fine with my iPhone.

Drain to 0%. Try to calibrate again. Charge non stop to 100% once drained to 0%.

I haven’t tried this yet as I was afraid it might start saying not charging at an even lower % or even just not turn back on.

I will give this a try though.

Thanks

Sounds like a hardware issue - the circuitry that regulates the current based on battery capacity seems faulty. You might need a physical repair to fix it.

I feared it might be a hardware issue! :(

Is this something that can easily be tested without taking the iPad apart and is it a costly repair job?

Thanks

I think this is a software issue. 2017 iPad pro 10.5” running 13.3.1 and an iPad mini 4 13.3.1. Both are clean install. Pro got to about 80%. Assumed it was an aftermarket screen repair gone bad, but the mini is doing the same thing. Separate Apple chargers, separate cords. Mini never had this behavior before fresh install. Mini charged fine yesterday, today stopped at 65%. I did a hard reboot, plugged it in after it was up and running and then shut it off. Hoping it will charge to completion while it’s off.
I’ll try running the pro down to 0 later tonight, not sure about it’s condition as it’s new to me.
Searches online turned up people having this trouble with 12 before. Hoping upcoming update will set me right.

iPad mini charged to 100% while off. Edit- Drained pro, threw it on charger, and turned it off. It has successfully charged to 100% overnight.
