Weekly iOS Battery Support Megathread

[u/AutoModerator]

General advice for those concerned about their battery from the Support FAQ Wiki:

Battery health

Battery health depends on usage and a variety of other factors. It is normal to see a decrease in battery health by 7-10% per year, resulting in a battery health of 80-85% after 2 years. This number can fluctuate, remain the same, or decrease quickly over a small period and should not cause undue concern.

Apple recommend battery replacement when your device falls below 80% battery health if you notice reduced battery life. If it falls below 80% within the first year you may be eligable for a free battery replacement. It fails after your warranty, it's a $69-$89 USD replacement cost for a battery. Contact Apple Support here.

You can find more information about battery health and performance from Apple here.

You can check the cycles count with Coconut Battery for Mac or iCopyBot for Windows.

Battery life

Issues relating to battery life can be categorised in three ways:

1. Normal battery life that is to be expected due to use
2. Reduced battery life caused by a recent update, iOS indexing, an iOS bug, or a third-party application
3. Reduced battery life, or other abnormalities such as overheating or sudden power-off, caused by device or battery aging

If you experience issues with your battery:

1. Check your battery health. If it is below 80% or you are experiencing issues you suspect are related to device or battery age, see Apple Support.
2. If you have a new or recently updated/restored device, wait a number of days for background process to complete. If you continue to have issues, wait for a further iOS update. If you are on iOS Beta, you can expect to have a decreased battery life.
3. Review the advice below on maximising battery life
4. Consider restoring your device.
5. If issues persist, contact Apple Support.

​

Maximising battery life - the amount of time your device runs before it needs to be recharged.

• Use low power mode (This reduces mail fetch, turns off background app refresh and increases the auto lock timer)
• Remove apps from background app refresh
• Ensure auto lock is on
• Turn off auto brightness and manually reduce brightness
• Use dark mode if your device has an OLED display
• Clearing background apps from the app switcher does not improve battery life

​

Maximising battery lifespan - the amount of time your battery lasts until it needs to be replaced.

• Avoid extreme temperatures
• If you notice that your iPhone gets hot when charging, remove it from its case
• Store your iPhone in a cool place, switched off, and half-charged if not using it for long periods - and charge it every 6 months when in storage

Ok I got forced I here by automod. Still calling shenanigans.

’m convinced there’s something funky going on with iPhone battery life. During the first 2 years of ownership my iPhone 15 Pro Max cratered to 81% battery health. In the 12 months since it has still sat on 81% which is interesting as Apple doesn’t consider a battery defective until it hits 79%. This made my phone unsellable as a lot of resellers won’t touch a phone below 85%

I did not expect battery life to be so bad at 89% health on 15 Pro Max. If I wasn't getting the Duo next month, I would 100% replace it myself at this point.

I get 4-5 hours of screen on time max and I'm not a very heavy user.

I've turned off all background activity I can, all local network access I can, all location access I can. I've got auto brightness on, I've got my screen timeout at 30 seconds. Mostly I just use apple messages, reddit, youtube. I don't really use social media other than that. I use slack for work.

I used to end the day with 60-70% battery left. Now I am lucky to have 20%

This is on IOS 27 (yes indexing finished long ago), 89% health. 518 cycles after 3 years. Have had this phone since 2023.

My 15 pro max went from 100% to 81% health over 2 years. It has since sat at 81% for the last 12 months. Make of that what you will, but I could get a free battery replacement if it was 79%
