I currently have an M1 11" iPad Pro, and it drains battery while locked like no other iPad I've ever had (I've had several). Usually to the tune of around 10-12% overnight. Did it since it was new when it first came out, every update hasn't changed it. Currently sitting at 85% battery health with 176 cycles.

In contrast, I still have an iPad 3 (yeah the one that was only out for 6 months) and after sitting unused, turned on but locked, for a month, it still has 56% battery left. And that's with 752 battery cycles and at 75% health.

From Here...

"While Optimised charging can be enabled/disabled on iPhone, an equivalent setting doesn’t exist for iOS/iPadOS for iPad.

iPad optimised charging for iPad is always active and will optimally charge the iPad battery - but differs from iPhone in that full charging to 100% is not delayed.

For iPad, charging may be limited to 80% charge when connected to its Power Adapter for extended periods - such as when used in Point of Sale (PoS) or kiosk applications."

Standby time has been very poor on iOS since iOS 12 for iPhones and since iPadOS 13 for iPads, even on their original iOS versions. There’s nothing anyone can do about it.

My facts? Tell me, how can I change the charging behavior on the iPad?

You want to dispute "my facts"?

In the end, the iPad is just a big iPhone and the 13" M2 MacBook Air destroys this thing while being cheaper. It's really Apple their worst device in their entire line up.

The iPad has so many limitations, that it even destroyed my battery.
The MacBook Air destroys the iPad Pro? It doesn't even have a touchscreen, unlike every other computer since like 2010!

It's not an emotional post. These are the facts:
- 16" M1 Max MacBook Pro = 100% battery health
- 13" M2 MacBook Air = 100% battery health
- 12.9 M1 iPad Pro = below 80% battery health

And the reason for this, is that Apple doesn't allow you to manage the charging behavior of the device, like what you can do on Mac.

The iPad Pro really sucks with the way it destroys batteries due to limitations Apple has put in place.
What’s your cycle count? What’s your charging behavior?

You’re making a lot of assumptions without providing any context.

I had an iPad Air 2 that had much better standby battery usage than this iPad Pro, even after iPadOS 13. My kid's iPad 8 & 9 also have much better standby time than my Pro does.
If by stand by time you mean screen off and not being used, I can charge my M1 iPad Pro 11 late afternoon to 100% and it is still 100% when I get up the next morning. It does go down to 96 to 97% by late evening on days I don't use my iPad, so my stand by experience is that my iPad battery only loses 3 to 4% in a 24 to 28 hour period. Seems acceptable to me.

A fully updated iPad Air 2 shouldn’t be good. Perhaps it can be better than your iPad Pro (12% overnight sounds utterly abhorrent), but that doesn’t mean it’s good.

4% in 24 hours starting from 100% isn’t good, considering that the 100-99% percentage point is 7-8 times longer than every other percentage point. That would mean you lose 10-11% in 24 hours. Not great.

My 9.7-inch iPad Pro on iOS 12 took 5 days to drop from 100% to 97%. It isn’t a 32-bit iPad, but it is far better than any current or updated iPad.

Yeah, I did an experiment where I fully charged the iPad Pro and then left it locked, just checking the charge level every night. It was dead 4 days later.
I have background refresh turned off and no apps open.

You will never have the same battery health as on Mac, because you cannot customise the charging behaviour. That is a fact.

It's not about a "data point", it is about there is no way to manage the battery on the iPad, like you can do on Mac.

Can you show me where in iPadOS I can change the charging, if you claim it is "emotional" and not a fact?
Hmmm, strange because my M1 iPad Pro from 08/2021 still has 96.1% battery health…. Heavily used, was my only ‘Computer’ for nearly one year.

You don ‘t say from when your iPad is but well, might contact Apple for a repair…. Not normal

Yeah, that’s beyond abhorrent. Sadly, there’s nothing you can do. Like I said, it’s not even iOS updates. iPads on their original iOS versions struggle with poor standby time. Apple broke something on iPadOS 13, and it hasn’t been fixed since.

iOS updates further worsening the issue doesn’t help at all, so a device that shouldn’t struggle after only one or two major updates suddenly has very poor standby time.

Which MacOS customization are you talking about because optimized iPad charging is always on? MacOS has low power mode, but that’s less about long term battery health.

Funny post. I usually go 3-4 days in between charges on my 11 inch M1 iPad. Granted that I have hourly shortcuts set up to automatically turn on airplane mode when it’s sleeping and i’m not using it, but the battery life is exceptional for me.

I'll lose 1-2% overnight on my M1 12.9.

A battery under 80% after 2 years has been left plugged in all the time while not in use, or left totally discharged for prolonged periods like several weeks (which happens when the device is not used regularly). Generally in both cases the number of cycles is relatively low, but the battery is rather degraded.
Having said that 80% from Coconut or iMazing does not mean 80% for Apple, it might take much more degradation before Apple accepts a battery service...
Having said that lack of battery health protection like on most Android phones and tablets, on most Windows PCs nowadays and on Macs is indeed an issue with iPads for those who do not use them regularly.
