is it true that once the iPad Pro reaches 100% charging and even after that if it is left on charging. The device automatically on its own cuts the power supply to the device. is this true ?

I left my iPad Pro on charging unknowingly for an extended period of time, even after it had reached 100% charging. I am worried could this affect the overall health and life of the battery of the iPad Pro ?

just Never drop below 20% nothing kills a lithium ion cell worse than a complete drain.
just like a Tesla it says zero 10% left useable power only in roadside emergency mode. In reality there’s another invisible 10% left that’s never available

overcharging cool not really a thing or possible. Unlike a Tesla which has protections draining your iPad Pro to 0% is a really bad move.

The opposite is worse.

As others have said, don't worry about it at all. While it's good to discharge your battery to around 40% and charge it back up once every few weeks (and while keeping around 60-80% is best for battery longevity) in practice, you can keep it plugged in as much as you want.

I think you’ll have a very hard time producing a measurable impact on the battery either way.

I have the first iPad Pro. It overcharges if I leave it plugged in too long and has been doing so for years. It is necessary to reset it (push both buttons) dozens of times. It goes through several blinking batteries, an apple, then on with a report of 100% charged, maybe to a selected app, then off again. I have to repeat this until I’ve run the battery down to, I guess, a true 100%. Annoying, but my fault for leaving it on the charger too long.

About iPad and iPhone charge-management feature - Apple Support (CA)

iPadOS and iOS include a charge-management feature to maintain battery health when iPad or iPhone XS, iPhone XS Max, iPhone XR, or later is connected to power for prolonged periods of time.
support.apple.com support.apple.com
www.idownloadblog.com

iOS 11.3 packs charge management for iPads plugged in for long periods of time

The feature reduces the maximum charge level when your iPad is connected to power for long periods of time and reverts it back to the previous level when conditions allow.

a lot of people forget about the charge management feature introduced in ios 11.3

You should try doing a hard reset of your iPad and set up as new.

No. You are fetching it from the thin air. There is no such thing as overcharging, and I also have that same model in daily use.

In addition, forced restarts are only recommended when the device is not responding, as in frozen but having a charge. Anything else a regular restart will do.

You’ll be looking at a defective battery at the most.

Never had any issues leaving mine plugged in once 100% or running it down to 0%.

just never left it sat at 0% for days on end

I’m the same, never had any issues with any of my iPads / iPhones. There more important things to worry about imo.

If this is the only thing the OP has to worry about in life then I want to be in his shoes 😂😂😂

To answer your question... No, your iPad won't overcharge the battery. When it reaches 100%, it stops charging. If the iPad is still connected to power and gets down to 95%, it will trickle charge back to 100%. Basically, the iPad will stay at 95 to 100% if left plugged in.

Now... There is still a concern. Even without overcharging, it's best to keep a battery cell moving. That is, either charging or discharging. If a battery will be staying at a certain level for a long time, that level should be 50% or thereabouts.

If you keep your iPad connected to power most of the time, at least once a week discharge it to 20% or less and then back to 90% or more.

That's it! Enjoy your iPad!

did you know that moving from 100% to 99% with Apple is roughly equivalent to moving from 99% to 95% if not slightly more?

If you're referring to when an Apple device jumps from 100% to, for example, 96%, that jump is because the device doesn't show the user the 95% to 100% trickle charge, discharge cycle. For simplicity, the battery meter simply stays at 100%.
