iPhone battery draining after iOS 18 Update

Hello~ Not I…my battery is holding up fine and I am using an iPhone 12 mini that is right at needing a battery replacement. Also…you will not “hear” anything from Apple here on this as it’s a forum of fellow users like yourself. What iOS version are you currently running?

During read of all this comments I found one thing that I didn’t do after update. And it looks like that helps and battery drain is gone now, at least for phone.

Background: I’m using shortcut to turn off charging at 90%. Probably charge to 100 is needed after update to calibrate battery.

my solution: Charge battery to 100% and keep it that way on charger for 1h.

before: phone charger before night, till the morning 30% battery drop.

now: after night 3-6% battery drop.

I have 15 prm before update my battery’s health was 98% but after it dropped to 88% I’m so mad it keeps dropping for no reason like when I don’t even touch my phone I have to turn on power saving mode constantly updated to 18.1 still no help

I've read the attempts of others (nothing helps). It seems that in my case, the battery drain is most likely caused by the modem.

I put the phone in airplane mode, and the draining stopped. So, basically, I have a phone that I can't make calls with, and if I want to make calls and use it, I constantly have to recharge it.

iPhone 14 Pro, and I've been having issues since iOS 17.6.2 (currently on 18.1.1).

I've already gone through a factory reset (which helped for about 3 days), countless recommendations for hard resets, then iOS 18.0.1 helped for about 5 days, but since then it's been the same.

I'm not planning on getting it checked for two reasons: 1. the phone is already out of warranty, and 2. the fact that a factory reset and one iOS version helped for a while (3-5 days) suggests more of a software issue. I was planning on upgrading, but I don't want to buy a new phone that will lose a significant amount of battery health within just a few months.

you have to turn off all AI functions. That’s what’s draining the battery. Once I did that, my phone has been fine. You have to toggle each individual one off, which is annoying, but it’s the only way. The software is constantly supporting the AI in the background. Settings>AI&Siri> Apps> shut all functions down specifically “Learn from this app”. Your battery will be back to normal. Thank me later

Today I showed this notification

Do I need also let the phone connected to wifi just to complete those? Or nah?

R u sure? I’ve got an iPhone 13 Pro Max will it do the same on this?

it's drastic, mine decreased by 1%

Mine is doing the same, fully charged on low power mode and battery has drained 15% in 20 minutes and I’m not using the phone
