Hi guys. I have a terrible battery drain on my Iphone 11 pro max.

Last night I charged my iphone to 100% and went to sleep. And 9am this morning it drains to 86%. So it lost 14% for 9 hours although no apps was running during that period.

Please have a look at my battery usage below. No app running when I sleep, but battery drains very fast. Anyone knows the cause of this?

I think you must to use iCloud if you have enough upload bandwidth on your Wi-Fi and secondly you can check your battery health and thirdly you must to update your iPhone to iOS 13.4 (just released)
You have to pay for iCloud subscription.
Sorry for my bad English
 
You can charge your iPhone during the night so your iPhone can work in background (like photos syncing and analyzing etc. )
 
My battery health is still 100%. I just got this phone for 2 months. So let me update it to 13.4 to see how it goes.

When you'll update your phone, can you describe your experiences with new update 13.4? I have same problem with my phone on iOS 13.3.1 100% Battery health, nothing drains battery in background but i think my battery don't last as everyone talk
 
I updated my phone to 13.4 and the battery drain is the same. Last night it drained from 64% (11 pm) to 55% (9 am) although it shows no app was running during that period. I turned off bluetooth, leave wifi + cellular on
 
Have the same issue.

Have the same issue. How long du you have your 11 Pro Max? I got my a week ago and at this point, I think the battery and system is learning. I noticed sometimes over night a 100% Siri use; in the middle of the night?
My daily use is 1-1,5 hr and I get 1,5-2 days of battery. But this is the same my iPhone X had after 2 years; so I hope 11 Pro max will improve itself.... soon !!
 
mine’s been doing that soo, seemingly for no reason. It’s infuriating and it didn’t do that before!!
 
I had the same issue but in my case it was mail background activity. However, I had all mail accounts in manual update mode only and low power mode on. I tried to DFU restore but same issue.

I then deleted all my mail accounts and added a single gmail account back and the drain came back, ~2% per hour even in low power mode. So I deleted the gmail account and started started using outlook and gmail apps respectively. The drain has not returned.
 
Let me share my experience. After updating to 13.4 I saw a degradation in battery performance from 13.3.1; I would say about 20 to 25% worst performance. After upgrading to 13.4.1 a few days ago, the battery performance seams to be back to al least where it was originally. On last couple of charges I got 9h:40min screen on time and 10h:50min respectively. Quite amazing I would say! I don't remember how much it drains overnight, but I will check and report back. My battery health is at 98% after 6 months of ownership.
 
I have the same problem with my Pro max. it lasts for one day with below average use. If I use cellular data and play Pubg or any heavy game it will last for 5 to 6 hours screen on time.
 
Hi guys, I have battery drain issue on my iPhone 11. It's not drained so much in background: like ~2-3% overnight. But I admitted faster draining then 1-2 month ago. What also interesting after restoring I've get 100% battery again while it was at 96%... Optimized battery charge doesn't work for my iPhone
