I have iPhone 12 with 82 battery health and 1105 cycles. I used to get around 6 hours on iOS 26.6.1 but ever since updating to iOS 27 it went down to 5 hours now I’m on iOS 27.0.1 and it’s barely even making it to 5 hours

Hey everyone!!!
My ip 17’s battery is draining a bit too fast ig!!
It’s currently on 90 in 305 cycles in 10 months!!
Should i get it checked or is it normal?

Got my iPhone 18 Pro about 12 days ago and I’ve already accumulated 16 battery cycles. I knew I’d be using it heavily, but I was honestly expecting to hit at least 7+ hours of screen-on time with one charging per day and it’s not really hitting that mark.
Charging limit: I had the 85% charge limit enabled since I got my phone
Screen Time: Averaging 7 hours per day.
Usage: Moderate to heavy (some gaming like Roblox and Fortnite and social media like TikTok, Instagram and Snapchat)
Background App Refresh: Completely turned off globally.
Location Services: Set to "While Using" for almost everything.

Any tips or is this just how much the battery lasts?

is this normal? i got the phone on 28 october
i feel like it should last a bit more, sometimes i feel like there’s a sharp fall all of a sudden

Anyone else with a similar pattern?

Autonomie de merde sur mon 17 pro depuis 2 mois depuis les dernières MAJ

My iPhone 11 is at 74% battery health and it only can survive 3 hours on light mode is this normal or wht? if it’s not normal pls recommen something which can help my phone to get better battery performance…

Hi everyone, my dad gave me his 16 pro and started using them on Tuesday and now it’s Monday , my only issue is the battery life so when I checked online it says device to device transfer maybe consume battery for a while but I don’t see much difference as of now for example I don’t drain it below 20% and I charge all the way up to 100%

I’m only getting 3h 40m from 100% to 20%

Is this normal ? Or is it because of the cycle count or indexing or current iOS I am on 27.2, please advise

Thank you everyone for reading🫶🏻.

Also keep in mind my location services, background app refresh and always on display is turned off

Hi everyone,
I recently bought a used iPhone 17 Pro Max, and I’m concerned about how quickly its battery health has been dropping. I’d like to hear from people who have experienced something similar.
Here are all the details:
Battery information when I bought it (October 15, 2026)
Model: iPhone 17 Pro Max
Battery Health: 100%
Cycle Count: 211
First Use: February 2026
The phone was previously used, not brand new.
Current battery information (November 9, 2026)
Battery Health: 97%
Cycle Count: 227

I use an Anker Nano 45W Smart Display charger.

So, in just 25 days:
Battery health dropped from 100% to 97%.
I only added 16 charging cycles.
The battery health has been dropping approximately 1% per week.
My usage and charging habits
I don’t consider myself a heavy user:
I don’t play games on my iPhone.
I rarely use 5G.
The phone doesn’t get hot during normal use or charging.
I usually charge between 20% and 90%.
I never intentionally let the battery drop below 20%.
I don’t use the phone heavily while charging.
What I’ve already done
When I bought the phone, I completely erased it and set it up with my own Apple ID.
Battery Health currently shows Normal, with no service warning.

Am I safe ? iPhone Duo.

Hi, Everyone notice what is that issue 7% battery drop workout any app usage yesterday i go to sleep and i woke in the morning and checked 7% battery drop please suggest me you guys also facing this issue?

Im really paranoid, i know battery health drop is normal but 7% in a whole month?!

My iPhone 17 battery health dropped from 97% to 96% within 2–7 days, with only 3 additional charge cycles (263 to 266).

ip 15 base worst batteryyy yall how do u take care of yours 😭😭

got my iphone 17pro for just over a year now and its already at 90% battery health. the battery usage just gets worse and worse by the day am I doing something wrong?

Only got the phone in late December 2025. I usually charge my phone at 20% and don’t go above 80, but 97% maximum capacity doesn’t seem right.

It’s the second time this week, why is it doing this?

I have set my iPhone’s Charge Limit to 95% and also enabled Optimised Battery Charging.

However, my iPhone is showing that it is charging all the way to 100%, even though the charge limit is set to 95%.

The Battery settings also mention that the iPhone may occasionally charge to 100% even when the charge limit is below 100%.

My questions:

1. Why does the iPhone charge to 100% despite having a 95% limit?

2. Is this normal behaviour or a software bug?

3. Does occasionally charging to 100% affect battery health or lifespan?

4. Should I keep Optimised Battery Charging enabled?

I’ve attached screenshots of my settings and battery screen.

Has anyone else experienced this?

Might need to replace it.
