Three Years of 80% Charge Limits on iPhone: The Results

Since 2023, Apple's newer iPhones have had an 80 percent charge limit for those who want to extend battery lifespan. Charging to 80 percent instead of 100 percent is supposed to put less stress on the battery, improving longevity.


For the last three years, I've used that setting on my iPhone. I started with the iPhone 15 Pro Max, then did the iPhone 16 Pro Max, and most recently, the iPhone 17 Pro Max.

After 12 months at an 80 percent maximum charge, my iPhone 17 Pro Max is at 97 percent maximum capacity with a cycle count of 277.


Last year, my iPhone 16 Pro Max was at 94 percent capacity after 12 months, and in 2024, my iPhone 15 Pro Max was also at 94 percent capacity.

During the year I tested the ‌iPhone 16‌ Pro Max, I tried not to let the battery dip below 20 percent. This year, I did the same thing, but I also tried to do more charging over USB-C than Qi2 or MagSafe. I'm not sure if that helped, but 97 percent capacity is the best result I've had yet with the charge limit turned on.

I don't know how my battery result compares to others, but if you've kept yours at 100 percent, you can compare your capacity to mine to see if there's any real difference.

Apple transitioned to aluminum and added vapor chamber cooling with the ‌iPhone 17‌ Pro Max, and I did think my iPhone spent less time uncomfortably warm than the ‌iPhone 16‌ Pro Max. It may be that the vapor chamber cooling made the biggest difference and limiting wireless charging didn't matter.

I don't use the iPhone 15 Pro Max or the ‌iPhone 16‌ Pro Max as my main iPhones anymore, but I do use them daily as test devices. They still have the 80 percent limit turned on, so I can share some longer-term battery results.

  • iPhone 15 Pro Max (36 months) - 88%, 369 cycles

  • ‌iPhone 16‌ Pro Max (24 months) - 93%, 343 cycles

  • ‌iPhone 17‌ Pro Max (12 months) - 97%, 277 cycles


Last year, my ‌iPhone 16‌ Pro Max hit 299 cycles by September 24. This year, I'm only at 277 cycles. It's nearly two weeks later than I usually report results too, so the larger battery meant less charging.

The ‌iPhone 17‌ Pro Max has a bigger battery and faster charging than the ‌iPhone 16‌ Pro Max, so an 80 percent charge limit wasn't as difficult to live with as it was in the past. I rarely ran out of battery, though I did still bring a battery pack with me most places. My favorite battery packs right now are the ones with built-in USB-C cables, especially those that can attach to my iPhone magnetically but charge it over USB-C. It's faster charging that's still convenient. I also continue to be a fan of the super-slim battery packs that add little bulk and weight to an iPhone.

For the iPhone 15 Pro Max and ‌iPhone 16‌ Pro Max, I didn't think sacrificing a fifth of my battery was worth the capacity I ended up with, and that's still mostly the case. I'm guessing my 97 percent capacity isn't too far off from the battery health readings on iPhones that didn't have the charge limit turned on.

As for older devices, my two-year-old ‌iPhone 16‌ Pro Max only lost 1 percent capacity from 2025 to 2026, and my iPhone 15 Pro Max didn't lose any capacity at all during the year. Both phones had fewer battery cycles (44 and 17, respectively), but they're holding capacity even after sitting dead for short periods of time throughout the year.

The most hands-off way to manage battery health is to use Optimized Battery Charging, since it minimizes time spent at 100 percent battery while still charging to full. Setting an 80 percent limit and then turning it off on days you need 100 percent is also a good compromise that could save you battery capacity over time. Apple has 90 and 95 percent options too, which might be a better choice.

My iPhone 18 Pro Max is already set to 80 percent, so I'll check in again in September 2027. I'm going to stick with USB-C charging when I can, and I'm curious how the even bigger battery will affect longevity and what the 80 percent limit is like day to day.

macOS 27.2 Further Hints at MacBook With Touch-Enabled OLED Display

The latest macOS 27.2 beta released this week further hints at the long-rumored MacBook with a touchscreen, which is expected to be unveiled by next month.


Specifically, when you click and hold on an app icon in the Dock on the third developer beta of macOS 27.2, the icon gets a little bit larger. A similar animation occurs when you long press on an iOS or iPadOS app, so the fact that the animation now extends to macOS could be another subtle clue that a touch-enabled MacBook is coming.

The new animation can be seen in videos shared by @madeby_ldt and @craigapplecom.

macOS 27.2 beta 3 introduces a new long-press animation for Dock icons, hinting at the upcoming touchscreen MacBook Pro https://t.co/4zfZOxy8MO

— ldt (@madeby_ldt) October 5, 2026


The latest macOS 27.2 beta added other new touch gestures as well, so it seems pretty clear that Apple is gearing up for the first touch-enabled Macs. In particular, Apple reportedly plans to release new higher-end, higher-priced 14-inch and 16-inch MacBook Pro or "MacBook Ultra" models with touchscreens in October or November.

In addition to a touch-enabled OLED display, these Macs are expected to feature M5 Pro and M5 Max chips, a thinner-and-lighter design, a Dynamic Island, and potentially Apple's C1X or C2 modem for built-in cellular connectivity.
