Battery Timing Issue on iPhone 12 Pro Max

varjack paw is correct. Your battery is nearing EOL (End of Life) or at EOL. Its performance is as expected and is shutting down when it does to protect delicate electrical components. You’ll either have to replace the battery or accept its worsening performance.

If your Battery Health is indeed just showing 40%, that indicates a failing battery which needs to be replaced ASAP. Apple recommends replacing the battery when the Health drops below 80%.

No tips are possible. Your battery is failing and needs to be replaced.

I recently replaced the battery on my iPhone 12 Pro Max, and it completely resolved the issue. Thank you, Apple Community, for the guidance—it made all the difference.

Thank you! My issue is resolved now. After trying several troubleshooting steps, including restarting the phone and enabling Low Power Mode, I finally reached out to Apple support, and they recommended a battery replacement. All is working fine now!

Thanks again, Apple community!

Thank you, with your battery health at 45%, it’s impressive that it’s still functioning, but it’s definitely time for a replacement. Apple recommends changing it once it drops below 80% to avoid performance issues.

On another note, if you’re planning a wedding, capturing those special moments is just as essential as maintaining your device. I am consider hiring a photographe de mariage ville de Monaco to ensure every beautiful detail is preserved in one of the most stunning locations with my apple phone.

Reduce screen brightness. Do not expose to direct sunlight. Reduce ambient temperature. If you’re uncomfortable (too hot) your iPhone is too.

Beyond that the heat generated by the device is caused by the app you’re currently using. Some app developers take great expense to produce efficient apps. other developers author less efficient apps which consume more processing power, battery capacity and as a byproduct heat.

My Battery Health is at 45%

It should have been replaced when it dipped below 80%. Amazing that the battery even works at all.

I'm also facing the same issue with my iPhone 12 Pro Max. My Battery Health is at 45%, and it drains fast even with minimal usage like browsing and gaming. I've tried Low Power Mode, restarting, and app updates, but no luck.

Interestingly, I noticed a similar issue after heavy GPS usage during a Hair Transplant in Brighton trip. Could background activity or location services be the cause? Any tips would be appreciated!
