iPhone battery draining after iOS 18 Update

Same here. It’s happening on all of my devices- iPad, iPhone and Apple Watch. On my Apple Watch I went from using 50% batter life a day from it dying by 9 PM after a full charge over night. Cancelled my Apple Watch data plan and not getting a new one. This was happening years ago. They had a class action lawsuit related to battery drain in the past.

Same here , after update ios18 my 14 Promax battery drainer fast just last half day,I also have problems with CarPlay it not connecting to play music hope apple do something bug fix or what ever improving

I have an iPhone 15 pro, since iOS 18 update, I wake up with 100% charge around 6AM, by 8.30AM with very light use , checking emails for example and some light social media, its down to 72%. I have to plug it back in to charge

I'm literally charging my phone every chance I get now, I'm charging it atleast 3 times a day otherwise if I'm outside I'll be stranded with dead battery (happened to me twice already) when I never had to charge more than once before. I reported this to apple support and they came back with usual BS. This makes me so furious, apple is constantly dropping the ball releasing worse iOS performance every release.

Ever since I did the update 18 I get on my phone in the morning and my phone is just draining so fast like it’s dead in like two or three hours after I use it before I got the update. It wasn’t like that I don’t know what to do with this. I have the iPhone 14 if you have similar problems like this and you know how to fix it please let me know

Same. Of course this happens every time after an iOS release but this is the most extreme case experience I’ve had. Phone is not even charging at times -meaning while it is plugged into charger the battery is going down not up and then phone overheats and stops charging. Apple should give you a choice to allow a long iOS upgrade overnight and get all these recalibration issues out of the way before using the phone again if that’s possible. it usually seems to go away after a while but your phone is always left degraded. This is by far my worst experience over countless upgrades.

I totally agree! My iPhone battery and my Apple Watch Ultra 2 battery drained suddenly just after the update to iOS 18!!!! I have to charge twice a day. Before the update, the battery lasted many days, especially the watch battery! Please, fix it!!!!

The iOS 18 update always or as I have noticed drain my battery faster than I have ever seen on any Apple device. Apple, please do something about this because it’s not getting any funny and It’s not good if you go out on a good day and you have your device go off in the middle of an emergency.

My iPhone battery went from 100 to 66% after installing IOS 18 update. As apple boss about a better battery life it seems that they just drained the battery or is programmed to drain the batteries. Apple should fix this big or replace everyone’s battery

I updated my iPhone Pro Max 15 to iOS 18.0.1. A message said, "Battery being optimized" for the next 6 -8 hours (2 o'clock in the morning). Today, the battery was completely drained. I'm legally blind, and need the phone to go shopping this morning. I can't get my groceries without it. I've become completely dependent on the phone, and that has given me independence. There are millions who depend on the phone to work properly.

i am also facing this problemy😔i have a new phone 13 ..After i update this 18 my phone battery draining too fast…before this update i watch 10to 15 vedio in youtube or else its consumed 2 or 3 percent of battery but now 3 or 4 vedio consume 7 or 8 percent for battery…besides this heating issues also added. what a drag man…apple have to fix this problem as the fast as they can

Apple … please react. After having sold billions of iPhones, how can this happen. This update completely screwed my iPhone 13… battery drains within couple of hours, iPhone is running hot when doing basic stuff, from time to time there are black screens and overheating notices. This did not happen before. And I am already on 18.0.1. problems still persist

BATTERY 🔋 DRAIN SO FAST

It’s so disturbing that I was excited for iOS 18, but it’s the worst update ever. My battery drains so quickly now that I have to charge it three times a day, whereas before this update, I only had to charge it once a day.

Plz do something how we can get back our normal battery backup plan

is there anyway where I can uninstall this update. I like my battery than this update.

Yes me too facing the same issue. The battery is draining out like anything. Battery which used to come for two days on low power mode is not even coming for 24hrs even. Am very much disappointed as i have bought my phone just a year back and facing this issue so soon because of this update. Apple which stands out for its features and technical capabilities is disappointing customers to loose the trust on the brand. :(

That's probably not going to help you much.

I am on a brand new iPhone 16 Pro Max, and it drains faster than my iPhone 14 Pro Max which was at 83% battery health.

All my apps were installed fresh. The device is brand new.

I live in Venice, Florida and I also upgraded to iOS 18 and had the same results, my iPhoneSE, doesn’t last near enough as before and I am charging it every chance I get. We are in the middle of Hurricane Milton, the hurricane of Biblical Proportions and I, now more than ever, need to stay in touch with friends, family and hurricane updates while we are running away from the landfall site. Way to go Apple, you’re supposed to help us with these updates not diminish the efficacy of our device.
