iPhone 16 Pro iPhone 16 Pro battery aging

[PowerPCFan]

As of lately I've been noticing my 16 Pro's battery getting worse, today I used nearly 180% of my battery after 7 hours of screen-on time... to be fair I was outdoors meaning cellular was being used heavily + brightness was high, but even "baseline days" have rather high usage and I find myself having to charge my phone near the end of the day for it to last

Any ideas for how quickly these batteries should age? According to settings - first use a year ago (June 2025), 341 cycles, 92% health. I'm on iOS 26.5.

I have to mention that I feel like the cycle count is pretty high given the length ive had the phone, that's nearly a cycle per day and it's pretty much always been like this, im not a particularly heavy user so this seemed a little unusual as well (well im on my phone a lot but doing basic tasks)

I expected to get a few years of good battery life out of this phone and it's been pretty disappointing to see it decline so fast

It's not too big of an issue right now but I'm not really in a situation where I could spend any more money on phones, I lost my original 16 Pro in May of last year and it was unrecoverable + no warranty/insurance coverage so I had to buy a replacement which really sucked lol

Well phone usage is very individual. U see all the infos in settings>screentime and battery.

calling 7hours „not a heavy user“ is downplaying the situation.

The 180% is high but a single day outdoors doesn’t help to see if in average your phone behaves unusually.

The obvious short answer is: the max phones would serve you better.

A day outdoors with high screen brightness and heavy cellular usage will hit any phones battery the hardest, and 7 hours of screen time is classed as heavy usage IMO!

Losing 8% of your batteries full charge capacity will start to show reduced usage time between charges, especially on a day like you’ve described burning through nearly 2 full charge cycles.

Battery replacements are a thing, zero need to replace the entire device.

No need to replace the battery yet either imo.

92% health is still good.

I more so meant the workload being done on the phone, not the time, although maybe that doesn't matter as much as you'd think

Tuesday was a more normal day and I used 105% in 3 hours 45 minutes

Any suggestions for how to extend battery life or slow aging besides lowering usage?

Check for the apps which uses the most battery. Usually GPS, games, video calls.

Regarding battery aging there are already dozens if not hundreds of threads on this forum

Do you have a lot of apps using background refresh? Or location services?

Seems to be mainly Discord and Instagram; and Flightradar24 on days that I use it which makes sense due to the heavy GPS usage

I'll search for some other threads

I've had my since about a month after the release, 507 cycle count and 89% battery health. It was doing really well...until I got iOS 27 DB1... but I find my still holds up all day (about 7 am-10 pm) with only 1 sometimes 1 1/2 hours of charging. That's with about 8 to 9 hours of music and/or audiobooks and about 2 hours of heavier use like games, mail, etc.

OP, it’s not “battery aging”. It’s your usage. Instagram, Flightradar with GPS use, high brightness, outdoor, cellular use.

You’re using your iPhone in some of the heaviest usage conditions. There’s absolutely nothing you can do if that is your usage pattern.

Go buy an iPhone 17 Pro and you’ll get the same results. High brightness, intensive cellular use is incompatible with good battery life. This has always been the case.

how come it still happens when indoors, on wifi, low brightness, and no gps usage? i get that a lot of times my poor battery life can be attributed to usage but there are also times where it seemingly drains for no reason. apple advertised "27 hours of video playback", those claims are typically exaggerated and short-form content does tend to be more intensive but i would still expect to make it through the day on a single charge when i'm in these less stressful conditions (no cellular/high brightness/gps)

yeah pretty typical with dev betas lol
thats still some pretty good battery life imo for that usage though

You get the same 180% battery use with 7 hours of SOT with low brightness, indoors, on Wi-Fi, with no GPS?

more or less, for example today I've used 90% so far over 4 hours, and last Monday I only had 3 hours 5 minutes of screen-on time and used 93% battery

Instagram is a battery killer but you shouldn’t be using a full cycle after three hours with low brightness.

Something is really wrong, maybe with your configuration or something. Restore and set up as new? It’s a pain, but the issue is odd so I’m not sure there’s another solution.

Yeah that's what I had been thinking, it seems quite odd... i tried disabling some apps' background app refresh and location services but that didn't seem to help, perhaps I will try restoring and setting up from scratch
