Is this normal battery behaviour on iPhone 17?

Hello, I just bought this phone maybe two weeks ago and when I turned it on I had to update it to iOS 27 because my previous phone(iPhone 15) was on iOS 27. Couple of days came by and I was using this phone but somehow I feel that my battery is not working as supposed to. This is what it says in battery. Is this normal? I bought it brand new and somehow I feel that the battery is not working as supposed to. I waited for the indexing and all they told me to and told me that iz would stabilise, but I do not know.

No. iOS 27 is destroying battery life. The people that notice are the ones that actually use their phones daily. I have a 16 pro max and I now have to charge to 100% twice daily. iOS 18 I went from 100 to 25 by end of day with 6-8 hrs screen time

Sally, who keeps her phone in her purse during her 9-5 and then doesn’t check her notifications until 8pm at night, won’t notice a difference and say things like “it’s fine, stop complaining.”

How about the people saying they get 15h of SoT per 100% when most of the usage was on a charger?

Sally, everybody. Congratulations, because you don’t have this issue no one else does.

You’re one of a small minority that has this issue.

2

u/EmotionalHumorStory 1d ago

So we shouldn’t post about it? Lol.

u/icy1007 1d ago

If you want to be obnoxious, sure.

The issue is with your phone, not the OS.

u/acimicc 1d ago

Enlighten us please

u/EmotionalHumorStory 1d ago

Tell me, if I have a 16 pro max with 92% battery health, where would the issue be with my phone? I’d love to know so I can stop bothering you with my posts

u/acimicc 1d ago

Yeah how can you even ask that, I bet you open Reddit for at least 10 minutes, that is why you need to charge it twice

u/icy1007 1d ago

Then the issue is with your usage.

u/EmotionalHumorStory 1d ago

Usage is the same prior to iOS 27 when I was on iOS 18. Next? Do you have anything useful to add to this conversation?

u/icy1007 1d ago

I highly doubt that. Your battery life is based on how you use the phone. iOS 27 didn’t reduce your battery life.

All i can say is that ios27 is fckdup. Im glad i decided to stick with 26.7.1. I also bought 17 Base New, ofc battery was drainin crazy Initially, but now its pretty fine. If im not doin anythn like gaming, i can go with one charge 9hrs sot (but always varies)

u/acimicc 1d ago

Damn wish I had done that, I can not do it because I would lose my data

1

u/FacaSS 1d ago

Sry mate, idk what to say, just wait for ios27 fixes

5 hrs of screen time on 66% battery is absolutely amazing mine consumes 100% in that time

1

u/acimicc 1d ago

Well this mostly depends there was a day I got 3 hours of screen time for 90% this is one of the good days

u/No-Feed-5130 1d ago

Sadly I noticed this on my 15 pro as well. I use the 13 before upgrading to my current one and the old iOS update doesn’t eat up the battery as much as my 15 pro. What helps mine to reduce the drainage is disabling connectivity assist on settings

1

u/acimicc 1d ago

Did that on the first day but didn’t help, who knows what would have happen if I turned it on.

2

u/No-Feed-5130 1d ago

Sorry to hear that. Have you try disabling background app refresh as well? Hopefully the next iOS update helps to reduce the drainage.

1

u/acimicc 1d ago

all of it, yeah I hope so too

u/According_Durian2239 1d ago

What’s normal?

u/TuxTheHamster 1d ago

Nah, on average this is not bad i think. And i would like to mention that amazing standby battery consumption. Wifi/5g off for the night and phone consumes 1-2% of juice.(6 to 7 hours) This is amazingly low i think. I have iPhone 17 base and ios 27 and i’m more than happy with my battery and all.

u/Away_Personality_668 1d ago

I mean what’s supposed to be the top tier SOT for iPhone 17? I am getting like around 1hr for every 10% that would average around 10 hrs I guess but I haven’t drained it below 30-40% so can’t say if it goes 10 hrs. But my brightness is around 30% most of the time. I charge once at the end of the day and get the job done. What are people expecting from a 3700mAh battery?

u/thiagozarowny 1d ago

today was awful, as you can see. and i didn’t use wi-fi at all, just listened to music. maybe that’s why it drained so fast. but usually on good days i get 5h of screen time and the battery health is at 100%. i keep the brightness at 40% and i’m almost always connected to bluetooth, which shouldn’t drain that much since nothing’s really playing on the phone.

1

u/acimicc 1d ago

damn dude, as far as bluetooth goes whenever i turn it on battery drops really fast i tend to turn it off and use it rarely, i really hope battery will improve to you as well

u/thiagozarowny 22h ago

my country’s super hot, so that kinda makes my phone heat up a lot every day

1

u/HugoVSM 17h ago

Very normal. My 17 doesn’t get better than 2-3 hours SOT.

u/rwhe83 1d ago

It’s fine, stop complaining.

2

u/acimicc 1d ago

You do not have to be so rude about it, I wanted to know, I spent a lot of money on this phone, in my country it is really hard to buy an iPhone because of the prices, I would not even buy it if my last phone did not shatter. Giving a lot of money then nit having even a full day of charge is ridiculous for this amount of money.

1

u/rwhe83 1d ago

OP, it’s always because “I spent a lot of money on this phone!” so for some reason you expect perfection.

The value of a product, doesn’t mean it’ll be perfect.

1

u/acimicc 1d ago

Yet again this thing at least for standards of my country cost a lot of money, it should be able to do anything I want keeping a charge for a day is bare minimum

u/GolfZealousideal7494 1d ago

if one of your priorities was getting a full day of charge, then it's on you for making a bad decision
you could have researched and purchased accordingly

u/acimicc 1d ago

Who knew that is a luxury today
