Terrible battery drain on my 11 pro max

It depends on the usage. How has your usage changed after iOS update.

Protect & Prolong life of your iPhone's Battery: About the battery usage on your iPhone, iPad, and iPod touch ...

Try some of these options too.

1. Avoid Screen Mirroring
2. Put on Low Power Mode
3. Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
4. Put Auto Answer Off
5. Disable Push notifications for apps you do not use often
6. Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
7. Manually lower brightness from Control Center
8. If you Want to watch continuous Video. Stream it on TV or a Monitor
9. Don't force close apps; Apps which are not on frontend screen are paused by the system to save energy. Apps require more energy to re-launch. Apps which are open in the background use large memory is a myth and quitting them is counterproductive
10. Location services to be allowed only while using the app
11. Set your iPhone to fetch email and calendar data from internet less frequently
12. Turning off Background App Refresh 
13. Charge before it drops below 20-30%
14. Try connecting to trusted Wifi where ever available in stead of Cellular
15. Enable Airplane mode in areas with bad cellular and wifi coverage. Your phone keeps trying for reconnection with the missing / weak network. This uses lot of energy
16. Switch off Wifi & Bluetooth while in Roaming or Not in Range
17. Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
18. Periodically Check your Battery Health (Settings > Battery > Battery Health)

iPhone Battery and Performance

I've been having basically the same battery drain problem on my 2016 iPhone SE. I found out it might help to switch off background refresh for all Facebook-made apps (Facebook, messenger, Whatsapp & Instagram), somehow they seem to drain the battery extremely quickly in the background since recent updates. At least you can try!

I've been on iOS 13.4.1 since release so that isn’t it. But I did call Apple and explained the battery issue as well as a heating issue that was mixed in or the cause of the battery issue and they are next day shipping me a replacement. So we’ll see if it’s a select hardware issue or still a software issue.

Been having the same problems as well with my 11 pro max ever since I went to 13.4.1.. it’s makings this phone useless to me cause I rely on it for work. But It’s weird because my sisters 64gb pro max easily gets 10 hours screen on time but on my 256gb I’m lucky if I get 5 hours. So idk if it’s on select models or she’s just lucky. Hopefully 13.5 will fix this..

I upgraded from an iPhone XR to an iPhone 11 pro a week ago and I’m so disappointed. The battery drains like crazy and the phone heats up for absolutely no reason.

this is ridiculous for a phone that cost me €1200.

My XR performed much better battery life wise.

It’s definitely a software issue because I returned the phone yesterday and got a brand new one that has the exact same problem. Battery draining so fast for no reason and heating up when I do anything minimal.

I’m so disappointed.

I have this problem too. The battery drains continuously all day to hit zero after about 12 hours of even low use. The phone is often warm to the touch all day. The battery usage monitor in settings seems to show random apps as using the most battery (including often Siri), but nothing improves when I delete those apps or turn off Siri, so I believe the battery usage reporting is incorrect.

The long list of options to protect battery life given in the official answer does nothing to address this problem. I have even fully restored the iPhone from iCloud backup and nothing seems to help. Apple, this really needs to be addressed as many, many people have been complaining about this for months.

Do you know Apple has an excuse for everything they advertise a pro max 11 with the best battery on the market you buy it and now it’s the worst battery on the market and all they do is give you excuses I’ll let you should do turn off this turn on this it’s a bunch of crap why in the **** does Apple fix the **** problem

You know what the best thing I think I still love Apple it was only thing I would have but they’re like everything else evil and don’t care about their customers because they have too many of them but every customer complains there’s not one customer I know that has an apple that’s upset with Apple the screen crack ther updateSScrew up your phone why do we keep buying apples I’ll be brainwashed by Apple I believe we are big-time brainwashing has got so big now it’s in everything thank about it

I actually experience the same thing too its heatinf up for some reason when i just updated my phone to 13.5. M battery drains faster! It is annoying

My 11 Max Pro was 100% at 9 am. At noon it is 20%. This was not the case before the last update of IOS. Obviously, this is more than annoying and unacceptable.

Yes me as well not happy !!!!

How do we fix as I just got mine July 25 and now it dies fast ! Use for 4 min and it went down 2 percent on bar ! Nothing different
