I have same remaining %, same number of cycles, but had phone 6-7 months longer.
6-7 months longer I think is good , but not under one year use and already 91%!
18.5 has been pretty good on my 16e, better than all previous 18.5 betas & RC.
Back to how it was on 18.4.1 which was waiting to install when I first powered it on at the beginning of March.

Surprised you didn’t use a charge limit! 16e does have it right? It should be.
Yes it does have the charge limits, occasionally goes up to 100%.
I came across this interesting video today:
The guy in the video suggests that charging your iPhone more frequently or for longer periods on the dock can potentially reduce the number of cycles recorded in the battery health stats. He also recommends using MagSafe more often. I’m curious, does overnight charging count as a single cycle instead of a few quick fast charges?
I’ve already taken care of other things like setting charge limits on my 15 Pro and only force quitting apps if there are any issues like crashes or bugs.

👀 I am at 97% 245 cycles!
300 cycles and at 9 months usage to be at 98%? Do you use MagSafe?
This guy explains how and why battery life drops over time and what can cause it to degrade faster. Heat is the number one enemy of batteries, so doing things like leaving your phone in the sun or using it while it’s charging (especially below 80%) will permanently degrade your battery.
I’ve also found that the degradation isn’t linear. Once the iPhone drops to 99% health, which can take a long time, it will quickly drop to around 90% and then start to slow.
My launch day 15 PM’s battery health is at 88% with 355 cycles. It’s been at 88% since at least 334 cycles.
Also not all batteries are the same. While all are guaranteed to start with at least a specific maximum capacity, some start with a higher capacity than others. As such some batteries take long to drop to 99% health, no matter what the user does. If your phone is a higher cycle count than others at the same health, you’ve likely hit the battery lottery.

Hey there, buddy! 👋
I’m feeling the same way about my 15 Pro battery. It’s been going from 100% to 99% in late April and then to 97% just a few days ago, even with iOS 18.5. It’s not just me, though! Many of us are experiencing this issue.
I went to the Apple Store on Memorial Day weekend because I had some errands to run. It was packed with people! After I explained everything I’ve done to keep my iPhone battery health up in good shape, including staying on the public version of 18.5. Due to the holiday weekend I couldn’t chat with an Apple Genius. They had a long list of appointments and weren’t able to help me.
I did share about the sudden drop in battery health that I’ve been experiencing to a few Specialists. One of the specialists asked if I had been running any betas on my iPhone, but I said no, I’ve been using the public release of 18.5 since it came out. I also explained how I keep my iPhone on a charge limit, use wireless charging and MagSafe sparingly, and only charge it to 90% when I need to.
Many of the Apple specialists told me that I’m doing the right thing by taking care of my battery. They said that if I have a chance to see a Genius the next time I go to the store, they can run a diagnostic test on my iPhone. I understand y’all it’s too early to get a battery replacement for most of our iPhones, but I would definitely go for it once the time comes. Since it’s not urgent, I can get my iPhone checked out and they can even add AppleCare to it given that I’m future proofing this iPhone. I’m happy to wait for that.
Despite the battery issues, I’m still doing well with my iPhone. I’ll restart it to see if the sudden drop changes.
Just watched it, and it is a great lecture on how the lithium ions play a role on our batteries especially how we should not underestimate cycle counts so often.
i agree with these statements and will also believe that it would be true on why it took me almost 5 months to hit 99% health then suddenly to 96% battery health as we speak. I did hear the myth bout the sunlight or heat generated by gaming or filming on power banks and that is why I leave it on my dock/MagSafe puck when i have my 15 Pro charging at home with it locked and unused until it is charged and well rested enough-
Batteries will degrade no matter what we do with our devices, sure it can be slowed down but it’s delaying the inevitable.
When I’m going to be out and away from a charger all day then I’ll charge to 100%, if I’m off and at home where I’ll have a high usage & screen time day it’ll be plugged into the charger on the 80% limit for many hours to avoid constant discharge and recharges.
18.4.1. Was on 18.4 since it launched and 17.7 before that.
I'm gonna wait a week or two before upgrading going further. The experience is really nice atm.
One major problem I am facing is overheating and low battery life. I guess it comes with every new update because there is no solution to get rid of this problem!
Yep, I charge it every night with a MagSafe charger.
Got it. That’s why I use a 90% limit for and when I go to school all day I keep it on 95% before but I don’t change it besides 90% for a few months now
