Do you really get 12 hours on an updated Air 2? Do you have a screenshot? Sounds a little (way) too good to be true, honestly.
With the iPads battery is something I just don’t think about - I charge them once a week and use them during the week and never run out but I’d have to check. iPad Air 2 is at work though so don’t have it to hand to give a screenshot - sorry.
I am absolutely sure it doesn’t get to 12 hours on iPadOS 15. 100%. Just check some results of 1st and 2nd-gen iPad Pros that have been updated and even with new batteries they struggle to get more than 6 hours with moderate use (mostly web browsing at moderate brightness). My 9.7-inch iPad Pro gets 10-11 with light use and low brightness, 0% chance a fully updated Air 2 is beating that. It’s not “maybe it may get there”, it’s “there’s absolutely nothing you can do to get 12 hours, other than reading iBooks at 0% brightness... maybe”. (For the record, I tested my 9.7-inch iPad Pro on iOS 9 just reading iBooks and I got 23 hours of screen-on time. Insanely efficient. Just to add info, with light use I got 14 hours of screen-on time, if not using that app I’d never get to 23 hours).
I do have a screenshot and I’ll share it.
This just upholds what I am saying - sure 8 hours SOT is excellent but also that was entirely in low power mode and based on usage of very particular apps. You need to compare it in a controlled environment for it to be reasonable to compare at all
Before you update, I'd recommend dumping SHSH blobs from the device so that you may be able to go back to iOS 12 in the future without needing to perform tethered boots using a computer (though this won't be possible for a long time). See this guide for two possible methods (unfortunately, they both require jailbreaking the device).
Different usage patterns have different battery life, absolutely, that’s obvious, but updates decrease battery life with the exact same usage and settings.
This is not true. Real-world usage is affected. Like I said, I can’t get to 14 hours on my 9.7-inch iPad Pro on iOS 12, and I’ve been trying for over 4 years. It just can’t match the battery I got on iOS 9. This is the case for every iOS device when updated far enough. We can discuss the merits of updating vs staying behind, but updates irreversibly decrease battery life and worsen performance. That’s a fact.
This due to battery degradation over time not due to iOS 12.
You are cherrypicking applications to show maximum battery life, when in fact if you used the phone in the sun on a bad lte signal battery life will tank.
No, it's a factoid masquerading as a fact. IE, battery life decreases with usage and later ios versions allow more concurrency. Better functionality is traded for battery life. That's not decreasing battery life "for nothing". Battery life just does not decrease and I posted a video showing that.
Completely false. Another very repeated myth. Battery life will not decrease regardless of battery health if the device is on its original iOS version, and if the device is updated, replacing the battery will not match the original iOS version. This is another paltry myth that people who haven’t tried staying behind keep repeating.
Battery life won't be affected by battery health as long as you never update it? what kind if load of crap is that? That makes absolutely no sense
If you're a power user as heavy as you claim and need more up to date apps, what exactly is stopping you from upgrading to something a bit newer? Not like you have to go brand new.
Efficient A12 users acknowledge that there has been a significant loss when compared with iOS 12. It's significantly better than it used to be and totally usable (unlike, say, the iPhone 6s on iOS 15), but it can’t match iOS 12’s numbers. Users can totally think that the features and compatibility they get are worth the battery life loss, especially considering that the device will probably still manage a full day (unlike older iPhones), but it’s just not as good.
So there is only anecdotal accounts of “unaccounted battery loss”? My anecdotal observations say otherwise that there are no losses that aren’t attributable to a aging battery.
Users also reported no perceivable decrease. I can’t absolutely say for certainty my Xs max never had a frame drop or keyboard lag in the original version of iOS. There is only anecdotal evidence no concrete proof.
In your anecdotal opinion of course.
Can you circumvent the websites issue with another device? It’s the most annoying issue on outdated devices. Like I said, I have the iPhone Xʀ on iOS 12 too and some websites also don’t work, but I try to use something else.
I will create one that is rigged. Low light next to the router etc. These battery graphs don’t have any iPhone identifying information, so I could use any old phone. They don’t have a date so they are strictly anecdotal.
Yeah, those issues are definitely due to iOS 12, and sadly the only way to circumvent them is to use a different device. Some apps also support older Android versions when compared to iOS, presumably due to increased fragmentation. Everybody just runs the latest version on iOS.
The fact these battery graphs can say virtually nothing tells me everything I need to know. Anecdotal. The fact you have to extrapolate also speaks volumes.
