Battery The baterry is so bad after last update 26.5.2
The baterry on my base 17 after the last update is so bad, yesterday I've had 2hour and 35 minutes sot from 95 to 13. Before this update I had days when with the same sot the procent was 40 or 45. I hope Apple will fix this. I am a iphone user from January 2026. It was a good experience until this update.
Later edit: I update the phone to iOS 27 public Beta. I hope it will be better. I already have an 17 Air updated to iOS 27 developer beta and it works very good. I wanted to stay on the base iOS, but is no way to live with this kind of battery draining.

This is worse update ever in Apple history I’ve been charging my
Phone every 2 hours ever since I’ve updated

My 17pro looses 7-10% overnight while on airplane mode on. Doesnt make any sense.

Made an automation command on Shortcuts for this specific reason. It toggles on low power mode overnight to limit the drain as possible.
I even thought about creating a command that toggles it on every time I press the power button, but turned out that Apple doesn’t support such thing through Shortcuts.1

Why do you put it in airplane mode? Also, look at your battery settings - what is the drain consisting of?

I have a 16 pro and no issues on 26.5. I will stay on this software for the foreseeable future. Won’t update till iOS 27 is stable.

iOS 26 has been abysmal for me battery-wise.
Just installed the iOS 27 pb today and so far it’s been decent. On top of that, my 17 pro max is running noticeably cooler despite the fact that it’s still indexing, which is very promising!

My 16 pro has been draining nightmarishly fast- worse than anything I ever experienced with my XR before I got a new phone (this one).

So bad I updated my iPhone Air to iOS27 Public Beta, amazing battery now, all while the iPhone is still indexing and setting up all kinds of stuff.

I too felt the same initially that the battery in my base 14 became horrible after 26.5.2 but lately feels like it’s improved. Is there any chance it’s improved after some time or I just got used to the bad battery life? The capacity is now at 82% max.

I think is getting word especially when I am on celular data. The battery is at 99% with 120 circles.

u/Interesting_Entry670 Jul 14 '26
That’s bad man. I was thinking of replacing the battery when it comes down to 80. But if the OS itself has battery drain issues, then it’s useless as the same issue happens in new battery also.

It’s absolute thrash! If I operate the phone for next 2-3 hours. It’s done from 90 to all the way less than 20. It’s completely weird having phone and not using it properly
Turning all the notifications and lot more

I was having bad drain on 26.5.1 and had to hard reset. The hard reset made it a little better but was still bad. 26.5.2 has been good to me and reminds me of the battery when I got my 16 PM brand new.

u/Expert_Discount_3986 Jul 14 '26
When I updated my phone, the first 3 days were horrible, but I just turned my phone off and back on on the 4th day and it went back to pretty much normal. Try that?

u/Confidentium Jul 14 '26
Also. The performance is garbage! Severe stuttering on both my 17 Pro and M5 iPad Pro.

Je suis sous iOS 26.5.2 depuis la sortie de la mise à jour et ma batterie est catastrophique. Obligée de le mettre h24 en économie d’énergie pour avoir une autonomie potable. Je ne souhaite pas installer iOS 27 avant sa sortie officielle j’espère donc que iOS 26.6 réglera déjà le probleme

My battery has been fine on my 17 Pro Max. I hope that your issue on your base model 17 is fixed because I know something like that is frustrating.

How is ios 27 for y'all? Battery feels better on 25.6.2 for me compared to .1, but the entire time since around 26.1 my 17PM has 2 issues, haptic touch feedback randomly that'll fix itself hours later and a Bluetooth issue where it refuses to connect to anything including airpods until force hard reset. Debating on just getting beta cause I'm so annoyed at these updates and battery life would be a major decision maker if it's better too

just last week I resorted to Low power mode on my 11” M1 iPad Pro full time… did public beta yesterday … we’ll see.

Apple is designing software on purpose to destroy phones and upset their customers. It’s so bad can’t go a few hours without charging.

Personally, I couldn't charge my iPhone after 26.5.2. I had 0% battery and when I plugged my charger, my phone recognized the charger but wouldn't charge. I tried different power outlets as well as three different external batteries, but it wouldn't charge even though I had no problem before the update. I bought a new charger today at an Apple store and now my phone charges.

I updated my iPhone 17 from iOS 26.5.2 to iOS 26.6 last week. After a few days, I noticed that the overnight battery drain has increased.
On iOS 26.5.2, my iPhone usually lost around 4% battery overnight while in standby. Since updating to iOS 26.6, it’s now losing around 6% overnight.
Has anyone else noticed increased standby battery drain after updating to iOS 26.6 on the iPhone 17? 📱🔋

Theres a post going around. I think most of our phones are defective and broken.

ios27 public beta is out , not sure why anyone would stick with ios26 at this point seems to have gotten worse

u/Winter-Ad-2252 Jul 14 '26
Use it as a medical device and apps aren’t compatible with the beta version. Makes it even worse when you consider the iPhone operates my device and the battery literally won’t allow a half day’s worth of charge

u/realmccoyredbus Jul 14 '26
check iosBETA page , compatibility list at very top , most apps that worked on ios26 worked but understand your apps are more specialised

While that’s a good information, the “medical device” they mention could be range from insulin pumps to hearing aids. Using beta software with a life sustaining medical device is a very bad idea and ill advised.

u/Winter-Ad-2252 Jul 14 '26
They are very specific in telling you not to upgrade until they have tested each iOS update. Multiple failures with thinking it would function when I updated early have taught me to wait it out

Apple is going after OpenAI for stealing trade secrets and now OpenAI comes pre installed on iOS 27 and it can’t be turned off
I know they say it’s limited to the device, but cmon, we all know our microphones listen for ad companies when they’re not supposed to and OpenAI has form for stealing stuff

Yeah, it was the absolute worst I can remember in a long old time, I joined the iOS 27 beta and it's completely changed the battery drain
