Standby time is a plague of iPadOS that is only getting worse in my experience. I have 2 pros on 18.5, 1 on 17.7 and one on 26 beta 3 (as well as 2 mini 5 on iOS 17 and 16) and while the beta is atrocious, we'll give it the benefit of the beta, but the others are pretty bad too... We are at a point were my Android tablets (tab S4, S7, S8 ultra and S9) have all way better standby time than iPads (1-2% overnight vs 5-10%).
And even Windows tablet do better but they cheat because after some standby time they hybernate unless you disable that).

Ugh, yes. Standby is just awful on both iPadOS and iOS on my devices even when brand new with no firmware updates. The only thing that reduces it is airplane mode (cellular, wifi and bluetooth all off). Even on low power mode, standby usage is still high (culprits being Find My, Home and Siri).

I've taken to scheduling a daily charge at 5am using smart plugs (with shortcuts to stop charging at 90-95%) to make sure my devices have sufficient charge for the day.

A question to both, if I may, please. What’s the newest device you two have and how’s standby there?

I’ll clarify: standby time is amazing on my pre-iOS 12 devices for iPhones, and pre iPadOS (13) for iPads. My iPhone 6s on iOS 10, and my 9.7-inch iPad Pro on iOS 12 have amazing standby time (as it did back with iOS 9)

My middle combo is utterly appalling. My iPhone Xʀ running iOS 12 and my iPad Air 5 on iPadOS 15 have utterly pathetic standby time.

But cue my surprise: I upgraded this past March to my iPhone 16 Plus and my 11th-gen iPad (A16). A gigantic improvement. Barely any drops, and I’d say that if they don’t match my pre-iOS 12/iPadOS 13 devices, then they’re very, very close. I was surprised. I cannot explain this, as their circumstances are exactly equal to that of my Air 5/Xʀ combo: fully original iOS versions. Yet there has been a massive improvement.

What’s your experience?

What’s your experience?
I should do some proper testing before answering this.
Here are my iPadOS versions:
2018 pro: 17.7.1 (still debating whether to update to 18 before it's too late)
M4 and M2: 18.5
M1: 26 beta 3
mini 5: 17.7
10.5: 17.5.1

Newest device would be M4 (came with 17), is that the one you would like me to test? Or others too?
I leave that plugged in at 80% most of the time so standby is not an issue thanks to this feature, but I can leaved it unplugged to test.

The 2018 one standby has been bad on every version of iPadOS, the M1 was better but with 26 beta it's not the worst.

I’m not sure how the various updates would play into that comparison, but yes, I think that the M4 with iPadOS 18 would be a pretty good comparison vs my A16.

The one that’s poor is my M1 iPad Air on iPadOS 15, but I’m not sure which one could be an equivalent. I’m not seeing it, because they’re either older and on newer iOS versions, or the devices themselves are newer.

The Mini 5 has an equivalent processor vs my standby-appalling iPhone Xʀ, but iPadOS 17 vs iOS 12, im not sure gow fair of a comparison that is. Do you have any inclinarion though? How’s the Mini 5 in terms of standby?

And also, what do you think would be the fairest comparison?

My iOS versions:
9.7-inch iPad Pro: iOS 12
iPad Air 5: iPadOS 15
11th-gen iPad: iPadOS 18

iPhone 6s: iOS 10 (by far the standby champion)
iPhone Xʀ: iOS 12
iPhone 16 Plus: iOS 18

Now that I think about it I have an additional M1 pro on iPadOS 15 and I think that one has better stand-by time, but I need to test it to be certain.
A relatively significant battery wear (under 90%, or even under 85%) may play a role in amplifying the standby drain, but my M1 on iPadOS 15 has a virtually new battery and the other devices are all above 90% but I will mention the wear to take that into account.

I actually have 2 mini 5, one on 16 and one on 17... with different battery wears, the one on 16 has less wear.

The only iPhone I have is an old SE on iOS 15 but I would not compare iOS and iPadOS as I think they are now different enough that a comparison might not be relevant...

The M1 Pro on iPadOS 15 could be an interesting comparison, but funnily enough, my M1 Air has the worst standby of any device I’ve ever used. SOT is magnificent, but standby is abhorrent. 4-5 hours of standby make it drop so much that it makes SOT testing irrelevant. That has never been the case.
 
The lack of Apple Intelligence is a bonus, too – I doubt it’ll remain optional forever.
Why is lack of Apple Intelligence a bonus? I use the writing tools frequently on my iPhone 16 and M2 MBA. My iPad 10 doesn't have Apple Intelligence, and I miss the writing tools. Especially, the "make concise" feature.

Me again, to say that sadly my Air 5, on its original iOS version (iPadOS 15.6), on Airplane Mode, with Low Power Mode on and every draining setting disabled… dropped 3% in three hours, for a daily average with maximum optimisation of a ridiculously insane 24%/day.

It’s completely unacceptable. There’s nothing I can do now, but it’s beyond ridiculous. I literally cannot be more efficient than this.

IMHO, life is too short to outsource my thinking to LLMs. The less AI the better.
