There could be several reasons why your iPhone 14 Pro Max is experiencing battery drain after updating to iOS 15.3.1. Here are some steps you can take to try and fix the issue:

  1. Check Battery Usage: Go to Settings > Battery > Battery Usage to see which apps are using the most battery. If you see an app using a lot of battery, try force-closing the app or deleting it and see if it helps.
  2. Turn Off Background App Refresh: Go to Settings > General > Background App Refresh and turn off the switch to prevent apps from refreshing in the background.
  3. Turn Off Location Services: Go to Settings > Privacy > Location Services and turn off location services for apps that don't need it. You can also turn off the "Precise Location" setting to improve battery life.
  4. Reduce Screen Brightness: Go to Settings > Display & Brightness and turn off "Auto-Brightness" and reduce the screen brightness.
  5. Turn On Low Power Mode: Go to Settings > Battery and turn on "Low Power Mode" to conserve battery life.
  6. Update Apps: Make sure all your apps are up-to-date, as older versions of apps can sometimes cause battery drain.
  7. Reset Your iPhone: If none of the above steps work, you may need to reset your iPhone to factory settings. Before doing so, make sure to backup your data to iCloud or iTunes.

If you've tried these steps and your battery life is still poor, you may want to contact Apple support or visit an Apple Store to get further assistance.

I agree, I go to bed with more than 50% battery and wake up today with 1% left. Bought this 14pro at Best Buy in April, it’s been a not so good experience with battery from day one and has gotten horribly worse. I’m not a phone junkie, a few times a day message ect.


If I go back to Best Buy they said I don’t have Apple care but their TOTAL care from BB. They’ll keep the phone for days to evaluate- so I’m living with the aggravation. Who can leave a phone for that period of time


I don’t know if the Apple Store will touch this if I don’t specifically have the Apple care.

Your welcome I was experiencing the same issues as you and couldn’t figure out why a top of the range phone couldn’t hold a charge since it has been repaired the battery life is unbelievable so it was an Apple issue and they sorted it promptly and said if it didn’t work they would give me a new phone. They also said it was one in a thousand that had that issue to me that seems quite high with the millions that Apple sell

Thank you for the information, I’m going to attempt to back it up on my laptop by creating a new iTunes account. I don’t have an iPad system just a regular laptop /windows.


Same issue happened last night, I had it fully charged at 9:30pm and at 5 o’clock this morning it had drained from 100% down to 56% by just sitting there sleeping overnight. (The night before it went from 52% down to 1% by just sleeping overnight.)


There’s definitely a problem here it’s just getting worse so I have an appointment at the Apple store on Wednesday and I hope they can figure out what’s going on with it without having to keep it for very long.

Yes your right some things work some things don’t some things they don’t want to tell us either just like the battery draining scandal a few years ago they didn’t want us to know they were playing funny games with that also and we all ended up with new batteries with that fiasco

There was no "battery-draining scandal". The issue was that, in order to prevent phones with already failing batteries from shutting off abruptly, depriving users of a phone they might need in an emergency, Apple throttled those phones with older batteries. Apple's big failure, what they got in all the trouble for, was in not communicating this more clearly. In response, Apple lowered the price of replacement batteries for a couple of years and refunded people who paid above that amount. Did Apple make a mistake? Yes. Were they doing something bad to people's batteries? No. Does what really happened make a much less exciting story? Absolutely.
