Mine has been a lot better today at 5% from 6am this morning

Interestingly, mine is doing much better today also. No idea why.

Me to I have the iPhone 13, I was alright with iOS 17.1.2 iOS battery life was great.

now this iOS 17.3 has lowered my standard iPhone 13 battery drop

increasingly

Just terrible after update. Phone would easily last all day, now dead by noon with no change in use. Battery health good. Hoping Apple will come through with a fix soon.

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.

Yesterday I update iOS, version 17.3 . my iPhone 13 battery draining so fast in one minute 4

to 6 % battery drain without using anything . How can I fix it?

I own an iPhone 15 Pro Max and the battery used to the last a whole day - with the new IOS 17.3 Update a new the battery drains out without a couple of hours

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.
