iPad Pro iPad stops charging at 100%

[Morac]

I have an iPad Pro 11. Lately once it charges up to 100%, the charging indicator turns off and the battery screen says it has stopped charging. When it drops down a bit it starts charging again. This causes the charging cable connected sound to chime periodically which is annoying especially at night. I think it started after 17.3.1. Before that the charge indicator would stay on.

Any idea how to fix this?

Mine only chimes like that when I'm using a third-party charger, not Apple's.

I’m using an Apple charger. I did a hard reset and it seems like it working properly now, but I’ll need to give it more time.

Also occasionally had this over the years. What worked for me was plugging the charger into a different outlet. But really unexplained, as if a temporary voltage incompatibility.

If solved by a reboot, sounds like one of the million unexplainable, weird issues that are solved by rebooting. I’ve solved endless weird issues like this one throughout the years.

Unplug the cable when its at 100%

Reboot didn’t fix it, but hard reset did fix it.

It only fixed it for a day. It’s back to stop charging at 100% or at least the UI and battery screen says it does as once it hits 100% the little lightning icon disappears, but the percentage doesn’t drop below 100% while plugged it. Maybe something changed in 16.3.1?

Can it be caused by overheating? I experience stop charging for a few times. When my ipad was plugged in but it stopped charging, I went to setting—battery and found message like ”the temp is too high, so it stops charging”. When your iPad is charged to 100% and kept plugged in, what does your ipad say in the battery page of setting?

Try a different charger and / or a different power socket.

It shows it’s not charging. It’s not too hot as the iPad is ice cold.

Basically once it hits 100% it stops charging.

I'm not sure why your charging indicator was staying on before when it hit 100%, and it's odd to me that it would drop a bit and resume charging. When I let mine charge to 100%, I unplug the charger. The next time I wake it up, it's still at 100%, even if it's been 12 hours or so.

I thought it was supposed to stop charging. In fact, the 100% displayed is not accurate. I've read that it actually will only charge up to about 98% and then stops, to avoid overcharging and damaging the battery.

It should charging the battery, but the lightning indicator indicates it’s connected to power. The iPad does some stuff in the background only when on power.

I did another hard reset yesterday and swapped out cables and it stayed charging all night. It did that previously after I did a hard reset and then stopped again, so who knows if it will make a difference.

The cable swap seems to have resolved this. What’s odd is I was using an Anker USB-C cable which is usually very good. That worked fine for over a year. I went back to the Apple one.

Interesting solution to the problem.
Do Apple have unique a chip similar to the Lightning cable that makes it behave differently?

Yes they have these important safety features for authentication and device protection.

The iPad Pro uses a USB-C cable not lightning and Apple says you can use any compliant cable. Maybe the cable went bad or something.

Yea, that's what I meant. If Apple do have added a bit of apple "intelligence" in their USB-C cables.
As you say, you can use any compliant cable but more since they did seem to behave differently.

But having said that, USB-C cables is a flippin jungle, both in terms of quality and standard.
