iOS 17.2.1 Battery Drain

I've the same issue on my iPhone SE 2nd gen. Before updating to 17.2.1 my phone battery would last for 1 to 2 days without charging. After the update it only lasts for 6 hours and that's when I don't use it and with WiFi and Bluetooth turned off.

Apple needs to fix this immediately.

I noticed looking at the battery usage that apps use way more battery after the update. Especially Spotify, which seems to just chug battery, even with screen off. Youtube aswell.

The difference is very obvious from before and after, and to note, i use the phone in the exact same way as I did on 17.2.

17.2.1 definitely has issues. Please apple release an update to fix asap. Today for the first time in 3 years my phone battery died in just 6 hours!

ios 17 had been very good with battery life until this rotten egg update

The same thing is happening on my wife's iPhone 13. For example, we charge her phone to 85% at night before going to sleep. In the morning when we wake up, the phone is at 57%. A drain of 28% with no usage other than standby. To check this, we closed all the apps the next day and the result was the same. I also see a similar thing with my iPhone 14Pro.

I have a 12 Pro Max which was fine until this morning.

I woke up to the notification that the phone had updated to 17.2.1.

My I used my phone for a good 2 hours today which led to losing roughly 25% charge, so still 3/4 full.

I drove home.

When I looked at my phone, it was suddenly at 25% charged. So 50% disappeared.

I charged it. Drove somewhere else, phone on car charger. Battery keeps draining WHILE on the charger. The charger shows that it is working.

I now restarted my phone and googled this.

will charge it fully and see what happens.

my phone was fine. This is absolutely due to the update

I am using iPhone XR, I know it’s quite an old model, but iPhones are meant to last long right? That’s why we shell so much money to own them. However got a battery replacement done today itself and shows 100% health. But after updating to 17.2.1 it started draining way too fast. Like just with a 7-8 minutes of screen on it’s dropping to almost 10%. Not normal it seems.

Same issue here with my iPhone 11 Pro Max. Noticed my battery health was 83% before the update, then immediately after it dropped to 80% without me doing anything… I use my phone the same way as before the update and my battery doesn’t last the same amount of time anymore. Feeling forced to upgrade to the newest phone rather than issues being fixed by Apple.

Battery health gets re-calibrated when the system is updated. So, what you're seeing is probably not a change in the actual battery capacity but a change in how accurately it's measured.

Why do you need to get a new phone? A new battery is much, much cheaper.

Went to the 'genius' bar today to be told that battery drain is normal, even though my battery health is 87%.

I explained to the 'genius' that I had no issues until the day I updated to iOS 17.2.1. He basically offered to replace my battery for £70! I felt like telling him where to stick the battery.

I have now updated to iOS 17.3 and the battery drain is even worse. BEWARE!

its actually the messenger and tiktok drains the battery. something is wrong with this apps, it seems that they are tracking us all day

download the Apple support App. it will tell u how to fix much of those really hard to reach Apple.. ios.. levels.. does. 💭

Do you have a problem related to the fact that the phone loses a couple percent of its charge within a minute in standby mode after a little use.

For example, I used the phone for a while and turned off its screen when the charge level was 30%, but then when I started using it again after a couple of minutes, the charge was already 28%

nice to hear that it's not just me
I bought my iphone 13 this spring 
but now after the last update 
the battery drains so much
 especially during the night 
when I wake up 30-40% of the
 battery is gone

I've just updated mine (iPhone 14 Pro Max) from iOS 16.7.4 to iOS 17.2.1.

Hearing a lot of battery draining issue happened on iOS 17, and I'm now start worrying about the draining issue.

May I know does anyone here have any issue on iPhone 14 Pro Max and iPhone 13 Pro Max after updating to iOS 17.2.1?

Right after update, my iPhone 13 mini is saying the battery is an unknown part. I’ve never had my battery or any part of my phone serviced. It’s barely two years old. Also it says it’s 1% even though it is definitely has more than that.
