iOS 17 | Battery Life & Health

[oMc]

I'd like to say that NO one can convince me that Apple degrades battery health intentionally. I have a 13 pro max. Last year when the iOS 16 beta came out, after my battery health stayed at 99%, as soon as I installed the first beta it immediately went down to 98%. Over the next few days it went down 1% per day til it got to 90%. After release it stayed there and did not move. I installed the iOS 17 beta and my battery health went down to 89%. Same thing, 1 percent per day.

I understand it's pre-release software that's buggy but that's quite the coincidence. My last iPhone was an 11 pro max and I had it for over 2 years and when I turned it in the battery health was 97%. and yes, I did not run betas on the 11 pro max.

Running iOS betas is known to drain the battery (= you charge your phone more often) and make the phone warm (= bad for battery), of course not for everyone, but more often than on stable release, for sure.
It's not intentional from Apple, you are the one deciding to test a beta software that has a very high chance of making your phone/battery working harder than usual.

Stop worrying about it, nothing you can do to stop battery degradation.

Well, while we cannot stop battery degradation, we can still slow it down.

For example, by keeping our devices as cool as possible, charging them with wired low-power (5W) chargers and tweaking power-hungry background processes to slow down unnecessary battery drain. Also, probably not running betas on devices with already depleted batteries. 😋

Battery life has been OK for me. Not the best, not the worse either. 🔋 💪

Aaron’s post is concerning, as he runs the beta on iPhone 14 Pro, if I am not mistaken. If this is that bad for him, imagine running the same beta on iPhone mini or SE - it might just toast their batteries.

Edit: installed PB1 about 6 hours ago on 12 mini - not bad, actually. No excessive heat and no extraordinary battery drain so far. Will continue monitoring it over the next few days.

What in the world is it that Apple is doing these last years? Every iOS is worse and worse. Is this the downfall of Apple? One would think that a company this big is prioritising their software, but I think the only thing they are prioritising is making more and more profit. Tim is really just destroying this company.

I hope you're just trolling.

No kidding. That was a terrible take.

These devices get more and more power-hungry, and the displays get brighter and brighter. And we still get 8-10 hours of screen time per charge.

If Apple removed all the processes and services that consume the battery (accelerometers, barometers, face detection, 2000-nit displays, etc...), you'd probably be able to get days and days of battery life. But it would be a pretty blah existence. Those are the trade-offs.

Once in a while, the complainers need to step back and look at how far these devices have come. If you used an early iPhone or the Nokia/Palm/Blackberry devices that preceded the iPhone, you'd realize what tremendous advances have been made.

And if the rumors are correct, the iPhone 15 line (with 3 nm chips) may be the most power-efficient yet.

And people will still complain.

iPhone 12, 89% battery health (original battery from October 2020, so not bad at all).

Battery life on beta 3 isn't terrible, but isn't great either. I can get around 4 hours of SoT with mixed Wi-Fi/5G usage (but mostly Wi-Fi). 5G really kills the the phone fast, but that's an iPhone 12 thing.
Phone gets hot fairly often when using some apps for a long time (Instagram, for example).

Hopefully future betas improve things.

Forgot to mention that optimized battery charging never worked a single time for me during beta 3, while it was fine during beta 1 and 2.

Looking forward to the new beta this week.

Where can I download iOS 17 Public Beta as a IPSW file?
Wanna try it too

I would give it a shot. It has made my phone useable again. You can find it on the Apple Developer website, just look for iOS 17 beta 3: https://developer.apple.com/download/#ios-restore-images-ipad-new

Maybe the ominous indexing will suddenly commence 😳

Steady going, perhaps I do not have much to “ominously index”, as most of my stuff is in iCloud? 🤔

So my battery health went from 100 to 97 on my 14 pro max after going from beta 2 to beta 3, should I be worried?

Health is now 94%, down from 100% since b1. 😤

Just chiming in to add that my battery health is down to 91% on my iPhone 14 Pro Max which is really disappointing since the phone is obviously not even a year old. B2 and B3 were really hard on the battery it seems. But that's beta life.

Just updated to iOS 17 beta 4. 🔋 Battery health degraded to 92%. iPhone 13 Pro Max. Down from 93%.

What you’re saying is true. Apple’s software-to-hardware optimisation is absurd (and by absurd, I mean astonishing, amazing). Updates are the issue. Grab any iPhone on its original iOS version: the 7 on iOS 10, the Xʀ on iOS 12, the 11 on iOS 13. Use it for years heavily and degrade the battery health to whatever you like. It’ll still work flawlessly, like-new. Sheer optimisation will manage to overcome battery capacity deficits every single time. It’s incredible. Thousands of cycles, sub-70% health, battery life is amazing on original iOS versions regardless.


It’s when you update that everything falls apart.

Crazy my launch day 14PM has the same battery health as your 13PM.

 

[morganthomas757]

Battery health on my iPhone 14 Pro Max launch day buy has dropped to 98% upon Beta 4. A bit disappointing as my iPhone 13 Pro I had before this never dropped any battery health in the time I had it.

For how long have you used your iPhone 13 Pro and what was its battery health to begin with?

I had the 13 pro for 7 months from Feb-Sep 2022 bought from new, remaining at 100% during that time, before upgrading to the 14 Pro Max in September last year.

My 14PM is just short of one year old, and battery health still reporting 100% I place the phone on a wireless charger when I go to bed, and plug it in in the Honda to use CarPlay. What am I doing differently than others who seem to be experiencing battery health issues?

7 months for a 13 Pro is a baby age, as it’s around 200 full charge cycles tops. The batteries start degrading much later in the game, so it would be interesting to check your battery health after around 500 cycles.

My 12 mini has over 800 cycles now and Apple reports 84%, while Coconut - 90%, so they do last quite a while, even in minis. 😉

Both your wireless and in-car chargers must be delivering a lower power input, compared to the wired 20W+ ones? Also, the less your iPhone & battery overheat during those charging sessions, the better for the battery. 👍

The 17.4 beta is sucking my barrety down!
Need to charge daily, at least.
14 Pro Max.

 

[coffeeplease]

Beta 4 was draining 10% a day on standby on my iPad, so I skipped installing it on my iPhone. Reverted back to beta 3.

I've removed Find my app and the battery improved
