After updating to iOS 17.3 battery draining severely

nothing is going to be done about this issue is it. It’s definitely this update, switching things off isn’t a solution. We bought these phones for all their functions.

what they are saying is ‘just don’t use functions that use a lot of battery’

i wonder if android phones keep getting these issues.

It kills the battery at abnormal speed! My iphone 15 pro is less than 2 months of use and the battery is already 99%. My iphone 13 pro’s battery dropped to 99% AFTER ONE YEAR OF USE, and 14 pro at leasts after 4-5 months. I always supported apple but this is too much. Will they compensate it in anyway? No.

iOS updates generally aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. Battery Drain issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

This seems purely coincidental so please check the Setting on your device.

45 years of Directing IT - I can tell you their Regression Testing procedures of vetting battery performance with respect to RC upgrades is garbage.

Exactly.. Firstly you pay 2000$ for a phone.. Then you don't even get a full day of charge for a phone..

Same experience with the iPhone 15 plus. Usually, I have to charge it only 3-4 times a week. Now, the battery barely lasts a day.

Me too. Noticed, with the same usage now, i may already be at 85% in 2hrs of normal use. I used to get back home at the end of the day with about 80% battery. Not anymore after 17.3. I have a 15 Pro Max with 100% batt health. What is this garbage ?

Im afraid I have the same issue. 13 pro max, less than a year old. Excellent battery on 17.3, once I upgraded to 17.3.1 a noticeably bad battery drain, even when idle. Like others, I purchased the pro max for its battery life, and its camera. Now the battery life is severely affected, not even lasting the day. My battery health is 95.

Xs with 17.3.1, battery is healthy, discharges few percents every hour, without any work on it, location, notifications, background refresh and so on, i.e. nothing is running, no any fancy apps installed, everything is refreshed, device is rebooted. What else can be done? To put it into trash? It looks like all latest versions of ios have their own hobbies and don’t care how much battery the hobby takes. Disgusting job…

_LL ~ Does your iPhone Xs still have its original battery?

And what's the Maximum Capacity % here?...
