iOS 14 Significant Impact to battery life.

I’ve noticed a significant impact to the battery life of my 11 Pro since installing iOS 14. I would average approximately 15 to 20% remaining end of day With average use. Post install I’m seeing between five and 10% remaining end of day.

Average use is approximately 5 to 6 hours per day with non-charge time of 10 to 14 hours.

It’s also safe to note that I’ve noticed a significant increase in the heat output of the back of the phone since installing iOS 14. Enough to become discomfort while in pocket.
How I fix This problem in my iPhone 11 Pro Max for Battery life and for slow down after new update iso 14
I’m also facing the same heating up problem when upgraded to iOS 14 of iPhone 11 Pro :(
My iPhone 11 its overheating after ios14.1 is installed. Its very uncomfortable to hold, never been this hot before!
To anyone having issues with ios 14, try to remove your sim card.

My girlfriend's iphone was having terrible battery drain and overheating. After removing the sim, the issues disappeared.
Same. Went to sleep Tuesday night with a perfectly functioning phone on the charger. Woke up Wednesday morning with a phone telling me it updated overnight but was like watching a countdown time when I unplugged from the charger. I didn't even have the screen or any apps on and it drained to 0% in about 35 minutes and was super hot to the touch. I plugged back in and looked up battery usage which showed Siri was running and eaten up 100% of the battery. Shut Siri off and it got maybe 10% better, but still pretty worthless. I shut the phone off and plugged it in for several hours until I new it was fully charged again. Started it up and same thing. Updated all apps and dumped ones I don't use any more. Went through all the settings and turned off location services and all background data, etc. Now it still does it, where it starts draining rapidly when opening or starting an app, then the drain will slow and drop off slightly, but still draining way faster than before and still getting hot with just the screen on and no apps running, and even with brightness turned way down.

Also since the update, Amazon Music won't work any longer, just crashes constantly. I hate Android operating system but it looks like my next phone will not be an Apple after being a loyal customer for over 10 years now. This is a pretty unacceptable flaw that seems a large number of people are having when 14 was released, then they just updated with 14.1 and didn't address any of the problems.
Solution:
Hi! I have been facing similar issue for months. Yesterday I find out its causing for my sim card. I pulled out my sim card from phone and the phone started woking fine.

Then I replaced my sim card now my phone 11 pro is working fine.
Lives in Sai Gon ( Viet nam ), same problem due to Sim. If your sim view is as this



Before iOS 14 my iPhone was perfect. I never charge it when I sleep and it barely drops. But after downloading ios 14 the whole phone starts acting weird. My battery health is 91% but when the percentage is 15%, the screen will start to lag as I’m swiping between different pages. Then the phone would suddenly shutdown with atleast 10% left. I don’t know if it’s a hardware issue or an software issue. Does anyone know what to do?

Same here:

Installed Update yesterday and a significant Battery Drain is notable -> before I had iOS 13 -> Usage all day without any Problems (Battery has still 82% Capactiy) 

Now I can watch Battery running down ...

Deactivated SIRI and Location Services and Widgets -> now it looses less Battery but doing Tasks -> E-Mail or Safari -> it drains again very fast 

This is a shame ... my iPhone has still 60GB Memory left and worked fine until the update and I am not willing to buy a new one. Apple has to fix this.
iPhone 11 Pro Max, iOS 14.2, phone is very hot to the touch to my fingers RIGHT NOW IN THIS FORUM ON SAFARI/IOS as I’m posting.
My iphone 8 suddenly over heated while charging over night and then went weird. Massive battery usage, normally a charge goes 15 plus hours but was suddenly down to 6. I spoke to a local engineers who asked if ios 14.2 had downloaded. It had so i was advised to install it. Gradually the overheating went away but i am still using crazy amounts of battery power. Phone is only 18 months old so don't want to and can't afford to scrap it. Come on Apple this seems to be a big issue for a lot of people.
I had significant battery loss after installing IOS 14 on my iPhone XR. I think I have solved the problem by firstly backing up my iPhone on iTunes then doing a full restore that also recovered all my files and apps etc. Just remember to turn off "find my iPhone" and turn off firewall protection. I also suggest afer doing the backup restart iTunes and the iPhone
I'm having the same problems: overheating and battery drain. Turning off location services and VPN are the only things that have helped. My Macbook Air also overheats all the time. I'm seriously thinking of ditching Apple altogether.
Same problem here 11 Pro Max! I just updated to iOS 14.3 yesterday and earlier I charged my phone and after 20mins when I checked, it was very hot to touch. First time it happened to me and as I was looking for some answers I came by this topic. My phone somewhat became a tad bit slow too, that it’s unusual because I get bored waiting. You know when you’re used on doing your routine, you’ll notice a difference when something is off.

When I first got my phone I had no problems, charging nor overheating (nothing!) and I loved how fast it was. Then I had updates and the same thing is happening with my battery, draining fast and went to draining so fast (same usage). That’s the first thing that I noticed.

Does anyone have an answer? Don’t tell me that my charger might not be the “original” or whatever bs they are saying coz they are! I got it from Apple itself when I bought the phone! No apps were running while charging, so cross that out. To add to that I still have 330 gb available capacity, so it’s not my storage that is slowing it down.
Also have the same issue with battery life, downloaded the recent bug fixes and constant battery problems and overheating off phone.

Has anyone heard from Apple on this?
