iOS 17.5 Battery Drain and Heating Issues

I have no problem with battery life on 17.5; you should look into what is using the energy. And it has been less than 24 hours since you were even able to update, so it is really meaningless to say that battery life is down without more time to collect data.

If battery life is down then SOMETHING is using energy that wasn’t; battery life doesn’t just vanish into thin air. Basic things to check:

• Force-restart your phone.
• If you have VPN installed, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile. If that fixes the problem you can reinstall it.
• Go to Settings/Battery and see which apps use the most energy.
• Wait a couple of days; sometimes after an update iOS will rebuild its database indexes, which can use extra energy. If you leave the phone plugged in overnight (which you should do every night) that will speed up the process.

I think updated devices needs 2 -3 days for the backround optimisation. Post that we can get the actual results of our device. Please update your observations after 3 days.

Same issue here.

For my part, CPU activity and therefore battery discharge seem linked to the background synchronization of contacts and calendars…

I had an alert on my iWatch storage full with 18GB of contacts!!!

So I disabled synchronization to iCloud of Contacts and Calendars…

I'll see if that improves things...

I’m also going through same issue my iPhone 15 pro max is getting hot battery is rapidly draining ! On iOS 17.5 I’m not a heavy user just surf the web phone calls, text messages and a little bit of YouTube and my battery is getting really warm and draining bad. 17.4 I got 2 to 2.5 days consistently on 17.5 I’m at 20% before bed on same usage as on 17.4. I’ve exit all my apps out done a hard reboot made sure nothing was running in the background but nothing is working.

Do you use VPN? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile.

Another iPhone 15 user here with the same heating and battery drain issue since updating to IOS 17.5 and then IOS 17.5.1

I was hoping 17.5.1. would fix the battery drain and heating issue but it hasn't... Battery brain is 20% to 25% overnight... It was usually no more than 5%... I've had about 3 models of iPhone at this stage (iPhone XR, 13 and currently 15) and I have updated each phone multiple times and this is the first time I've updated and experienced as bad an issue as this... Ironically enough one of the reasons I switched from Android to the iPhone a few years back...

I decided to erase the phone and set it up again from an iCloud backup... A little bit of a pain to do but if it resolves the issues it will be worth it... I will update this post if it improves the battery and heating situation but it will be a couple of days before any difference will be noticeable...

It's disappointing that Apple would release an update as bad as 17.5 and 17.5.1... I'll be waiting for the online feedback on any future IOS updates before upgrading again... Experiences like this diminish trust in Apple's competence...

Same here. I’m on 17.5.1 and my battery drains really fast. I noticed that Apple News is taking up over 25% of my battery usage even though the app is closed and all the background downloads are turned off. I recycled the power on the phone but can’t get Apple News to stop hogging battery life.

I’m also going through same issue my iPhone 15 pro max is getting hot battery is rapidly draining ! On iOS 17.5 I’m not a heavy user just surf the web phone calls, text messages and a little bit of YouTube and my battery is getting really warm and draining bad. 17.4 I got 2 to 2.5 days consistently on 17.5 I’m at 20% before bed on same usage as on 17.4. I’ve exit all my apps out done a hard reboot made sure nothing was running in the background but nothing is working.

Similar to me, 15 pro battery draining noticably quicker. I have not faced any heating issues and idle discharge is normal. But my usual uses drains the battery thatI can see the battery % dropping in front of my eyes

My iPhone 15 Pro just went from 50% when I went to bed to dead the next morning after updating to iOS 17.5. I can see in the Settings app how it went down while I wasn’t using it, no apps in the background, all apps have the background update turned off. Before upgrading I would get more than a day of use since my average use is around 1:30 hrs a day. Every update has made my battery worse and worse.

After updating to iOS 17.5 I observed my battery health gone down from 100 to 99… battery drains faster compared to the earlier version.

As of this writing my phone’s Batt health just went down to 98.🤦🏻‍♂️

Sudden drop of battery life 2% within a week as compared to last 15 months of stable battery health & unusual overheating of the device is really disappointing & minimising trust on apple products. All happened after update to IOS 17.5.0 version.

apple seriously need to resolve customer complaints since they fail to address such issues being a tech giant. Disappointed

Another update, another **** show. Apple once again goes after the battery performance (didn’t they get sued for this?) and now cellular data doesn’t work either. Just proof Apple is out to cheat people again and one more reason why I am no longer buying Apple products

mine is on 17.5.1. just scrolling twitter or some light apps, phone becomes very hot like playing heavy graphic game, and battery is drop very fast ... what did they do? kill our battery before announcing iphone 16s?

Having the same problems with everyone else on this forum

iPhone keeps having big power drain

Started with iOS 17.3 and has continued since, on subsequent updates Inc on 17.5 which is what I'm on now

I recently upgraded my Iphone 12 to iOS 17.5.1. Now getting heat issues everytime I try to charge the phone. I've tried rebooting, turning off the phone, checked settings, etc. but still the same problems.

This didn't happen when I was using the previous version of iOS.
