I charge my iPad overnight every night and have done for a few years. The battery seems to run down very quickly. even if it is plugged while I am using it, the percentage still goes down, just a bit slower. I recently bought a MacBook Pro and want to know if a) charging overnight kills the battery in my iPhone or iPad, and b) if it will kill the battery in my MacBook. Thanks
iPad Pro Wi-Fi, iOS 12
No.
The idea that charging phones or modern electronics overnight will harm the battery is a myth based on very old battery technology in devices.
Check out this link:
Battery health does degrade overtime naturally, and has nothing to do with charging overnight. But you can check the health and performance of your iPhone battery: iPhone Battery and Performance - Apple Support
And on MacBooks go to About This Mac<System Report<Power

Well, that what we have to advice where I work, and I Have seen the same people in because they are always leaving there charger in 24/7 and needed quite a few batteries replacing the boss told them to to take the charger off after it get to 100% so it can be drained! Funny thing is we don't see them coming in regarding batteries problems anymore like they use to!
Unfortunately, I can only go on what he said, I know all the other stuff but batteries is not my domain!!

Or, they realized they were getting bad advice and stopped coming back. Or, they never really had problems with their battery in the first place so telling them to do something that actually did nothing made them feel better about things.
Once the battery reaches full charge, the circuitry in the phone stops charging it. What you're suggesting won't hurt anything but it won't actually help either.
I spent twenty years doing tech support and customer service for a major U.S. cellular company. I received training from cell phone manufacturers, including Apple.
No. Apple products have intelligent power supplies which charge batteries correctly.

Always let them charge to 100% you can still use your ipad while working and then unplug it as it likes to drain rather than it being charge constantly in!
This is not necessary. You can charge your device whenever you need or want to. You don't need to always charge to 100%. You can leave it on the charger even after it's 100% charged. It won't hurt anything.
You can leave them plugged in all the time, this will not impact your battery life.

No they come back, just not regarding batteries anymore, now let close this off since it resolved,
Also you learn something new everyday! Thank for telling me !
Shhh I’m going to advise differently from now on about the battery!
😎
Hi,
I do the same, I suggest this to everyone, Always let them charge to 100% you can still use your ipad while working and then unplug it as it likes to drain rather than it being charge constantly in! I charge my iPhone and iPad everynight and I don't seem to see any problem with batteries It maybe due to the age of the device.
does charging apple product overnight kill their battery.
