Hello after 17.5.1 update i encounter extreme battery drain and life drop from 90% to 86% after update. Battery drains almost 50-60% in 4 hours without using it before update battery lasts almost day and half without charging!

For everyone having battery issues immediately after an update (within 1-2 days) here is a guide.
*** FYI, I shamelessly copy/pasted from articles Apple has on this site for your ease of use. I didn’t copy/paste when animations on the link will be helpful.***
First, understand that the software does housekeeping after an update. It can usually be accomplished overnight but that depends on your device and its data. Try to install updates overnight and leave the device on the charger (It’s ok to do so and won’t ruin the battery. That rule applied to older battery technology). This is so that processor intensive tasks like file indexing for Spotlight Search or iCloud syncing can occur then and not during your day.
If still dealing with drain after two days it’s probably something else so we need to become detectives and use the Settings > Battery section to see which apps are the culprits. Check under the View Battery Usage Information
section here: Batteries - Maximizing Performance - Apple (bookmark that link for later)
If nothing stood out on the battery usage, next check all apps for updates in the app store. To do this:
on your iPhone.
or your picture at the top right.Install them all. Feel free to do some spring cleaning on apps you no longer need also. Here is how:
Do any of the following:
Next, if any apps in the Battery Usage showed background activity, look at Background App Refresh (Settings>General>Background App Refresh) and turn off any apps that should not be allowed to be active when you aren’t using them.
Basically, if you lock your screen or move to another app, do you still want that other app running in the background?
Map apps, fitness apps and music apps like Lyft, Waze, Strava, Spotify, etc are examples of ones that you may want to keep on. They need to keep working even while the screen is off. Facebook, TikTok, Instagram etc are ones you may not want on unless it’s important you are notified of everything as it happens even if you aren’t in the app.
Now that everything is up to date and you’ve eliminated any frivolous battery usage, use the phone and see if that helped.
If not, next try closing all applications (helpful animations on this link):
(Close an app on your iPhone or iPod touch - Apple Support ) and restarting the device: Restart your iPhone - Apple Support
If this still didn’t help, try a force restart (helpful animations on this link. The title is for a different scenario but it is the correct link): If your iPhone won't turn on or is frozen - Apple Support
After all of this charge back up to 100% and give it a go. If still having trouble then give Apple or your family tech support (your kids, niece or nephew ;) ) a call.
I hope this helps. But to reiterate it is normal for the battery to suffer immediately after an update. All that housekeeping that gets done plus your regular usage taxes the battery hard those first days. I always leave my phone on the charger overnight after an update and it rarely ever gives me trouble. I have had the iPhone 4, 6S, XR and currently 13 Pro and used similar principles across all of them, except where the iOS features differed. Never got rid of a phone for battery issues but I did replace the battery on my 6S when it reached the end of its useful life around 70% Battery Health.
Cheers all.
At this point my iPhone is absolutely useless. 😞 I have an iPhone XS Max since 2018. iOS 17.5.1 just destroys my battery. Leave home at 9am at 100%. Doing absolutely nothing at 2pm have 0%. What is going wrong? 🤔 My battery health is at 79% after all these years, I know it needs a new battery, but still…. Before iOS 17.5.1 battery lasted all day from 9am to 22pm. Now I have to leave home with a powerbank and a lightning cable 🤦🏻♂️. I’m not buying a new phone, this one is perfect, works well, fast like the launch day… but this battery draining issue 😞
After I updated to 17.5.1. i lost 3% battery health in a week and before i lost 1% in 7 months. Battery life is almost unusable for me I have iphone 15 pro thats is 7months old and my battery went from 100% to 46% in 2-3h oh usage. I expect a suitable compensation from apple.
standby battery timing is worse on my iPhone 15 Pro Max after updating to 17.5.1. every night i charge my iphone to 100% and turn off wifi aswell. the battery drop from 100% to 90% daily without even touching my iphone. it
Same issue - noticeably excessive battery drain after 17.5.1 update.
Same issue across 3 devices - iPad Pro / iPhone12 / iPhone SE 3rd Gen.
Devices been used in same manner since new, no changes made to settings and then hey presto after update, having to charge more frequently and battery draining even when devices sat not being used.
I have the same issue!! It’s the first time that i have to charge my iPhone 15PM twice a day!! I don’t know if it is because the software or the hardware itself!! Because it’s nonesens that the battery’s performance got to be impacted by the update of ios!! Normally the update should come with improvements not with the same issue of draining of battery!! I think this is a disadvantage of the pro processor of iPhone pro!! I hope apple fixes this issue with the upcoming updates of ios…
I’m having this issue too with an iPhone 13 Pro Max, fortunately a MagSafe charger charges it. Although it does drain so much faster than it did before and now lightning charging isn’t working. I’m so glad I came to these forums before replacing batteries and what not.
I update my 14 Pro to 17.5.1 yesterday and battery drain instantly went down 20% , Phone stays constantly hot! and phone used to last all day no problem now my phone drains battery life like crazy.. I charged my phone overnight and it only got to 77%??? my Battery Health says 92% and I have had it plugged in to charge at my desk for the last 20 Min and it will not move up from 75% ( battery icon is green and shows lightning bolt ) My Phone worked perfectly 2 days ago now I have major problems....this is ridiculous
me too iphone15 pro max after 17.5.1 updated , battery significant drain but on the other hand i’ve felt my iphone run faster and looks faster in UI and application running
so maybe faster battery drain come with faster engine
Same here! Hubbys phone gets so hot on or off the charger and his battery drains 20% every hour even without use it’s ridiculous so we’re gonna call customer service and see what they can do for us cuz we rely heavily on our phones for work
i upgraded yesterday, from my iPhone 11 with battery life bellow 80%, to a brand new iPhone 15 pro. I must say, I find it strange the speed that it is discharging. 100% at 8h. It’s almost 23h now and I have 14%. I didn’t even have the phone much use. I don’t think it’s normal, as my wife’s iPhone 15 that she also bought yesterday is at 54%. I really hope it’s a software issue.
I am so disgusted with this issue happening again! A while back an update caused this same battery drain issue… and here we are again, only worse this time!! They need to get another update to correct this NOW!
Why you answer in that forumn it always user error alway it not mine usage behavior i'm use my iphone 14 pro with normal use but now my phone was broke now battery drain very fast and too much bug it because it software dev not my phone problem if you call that answer in that forumn it problem with user error you don't write in this forumn please ! Ios since ios 17 updating phone not working now apple please re read this forumn! And write software properly Please it very bad software dev to release software to people to use it mine can't used my phone at single charge now screen on time it only 3-4hour only!
Same here. I just got iPhone 15 Pro a couple of months ago, just for the battery performance. I was streaming on youtube almost 8 hours nonstop, and at the end of the day my battery was 30% after updating to 17.5.1 now I need to charge the battery midday just browsing, no streaming. This is terrible
Me too. Since updating my 1TB iPhone 13 Pro to 17.5.1 it's been unusable. Battery health shows 100% but battery charge can drain from 100% to the red zone in less than an hour, even if the phone isn't being used. Sometimes I get up to six hours, but that's nothing compared to the nearly two-day life I had before the update. What I currently have is a £1,000 plus paperweight!
My iPhone is going down 1% about every 3 minutes, only noticed this 2 days ago. Listen to podcasts during 8 hours of work and usually come home with 70%. Yesterday and today I’ve had 15% about 4 hours in.
also noticed my iPhone seems to be roasting just going on safari.
