My iPhone 12 mini's battery drains too fast after iOS 17.3 update

After downloading my iPhone12 to ios17 my battery is draining even after charging it to 100% capacity! Why??? How can I go back to ios16??? This is ridiculous! Every time there’s an iOS upgrade or update Apple always has issues!!! Don’t they EVER check these iOS updates prior to putting them out? It’s unacceptable and very annoying.

I do that too! I wait at least a month before I update the new iOS update but it doesn’t seem to matter! There’s ALWAYS TONS OF ISSUES AND A MILLION MORE IOS UPDATES AND FIXES. SO VERY UNACCEPTABLE! Apple! Start testing your iOS updates!

Experiencing the very same issue, however the battery issue has worsened - was bad before now 5 hours from full charge to 10 with 100 battery life

13 PRO MAX, same. I lost 96% of battery in three hours. 3… 1/3 battery loss per hour, when the day before I had around the same scren time and went to bed at over 70% !!! Im flummoxed…

Same here, iPhone 14 Pro Max battery life is horrible! Normally holds for all day but now need to recharge 4-5pm again to made it.

After this update on my iphone 12, its battery drains fast even when I am not using it. Terrible! You have to find an immediate resolution for this.

Another iPhone 12 mini, which drains with normal use in about 4 hours.

Apple updates just get worse. iPhone 15Pro drains to 20 % in about 14 hours. Just awful. About 1/2 the performance before updating to 17.3. Seriously starting to feel like I am back to using Windows products that fail on basic functions….

I have an iphone 14. Same issue, my iphone never went down to 30% or less in the same day. I am having to charge it every night or morning now. What gives, Apple? When I first got it I would brag that it would go 2-3 days on one full charge. Not anymore. =(

Everyone,

As with everyone my iPhone 14 Pro experience with update 17.2 was so much worse, very poor battery life - battery barely lasted 3/4 of the day, and the phone was always hot, during use and when charging was worse before the 17.3 updates, however, the battery is much better and lasts all day, the back of the phone remains cold during use and charging.

14 pro max here. Had great battery performance. I never charge my phone while i sleep. When i went to sleep i had 31% battery and in the morning it was shut down. It s second time when this happens, usually i would go with even 7-8% to sleep and in the morning i would have 3-4%. My gf has 12 mini and her battery life is worse too after the update. The problem with this update is the off screen consumption for sure. Hope they fix it pretty fast

I have iphone 15 pro and battery drains really fast, even during night when i have everything turn off. Wifi, bluetooth, "cellular data", hot spot,... everything is turn off and from 76% went to 35%, it´s almost impossible to use it...

Conditions of batter is 100%

my iphone 15 plus has same issue after the ios 17.3 update. the battery drains 5-7 % overnight i dont know what sort of sorcery is that. i dont use the phone and it drains that much battery. in settings battery it shows home &lock screen usages. i had 13 pro max on ios 17.2 and the battery life was so much great than this new 15 plus.. i bought it few days back thats why i couldn’t got the 17.2 update insted i got 17.3 as they released this update and removed 17.2 and because of the heating issue that iphone 15 series had after launching i upgraded the phone now i REGRET doing so.. wish i got the 17.2 update.. i have tried upgrading the phone from pc and then hard rebooting and turning off many features.. i spend this much money and can’t even use the phone without worrying.. apple is dying i think. each new updates brings new problems so apple is problem lol.. now they are working on 17.4 i think they will not fix the battery issue until 17.5 lol what a shame.. I WILL NEVER UPGRADE MY PHONE EVER AGAIN WHEN I GET AN BATTERY OPTIMIZED UPDATE. and then no updates will be made in my phone

Same issue experincing on iPhone 12. After the update to 17.3.1 I am seeing worst battery performance. Also battery health is deterioratimg quickly. Before the update, battery health was at 85%, now with only couple of days with update I’m at 79% battery health… please advise on this.

This always happens to me eventually no matter which iPhone model I get… eventually, I update my phone and the battery suddenly drains so quickly. Apple just wants your money so you have to buy a new phone. Kind of a scam… thinking of switching to an Android.

Stop scamming people, Apple.
