iphone 14 battery health dropped after a month

I got my iPhone 14 in 25/11/2023 and it was a brand new one. It comes with ios 16 and after week i updated it to ios 17 Ater three weeks I noticed battery health dropped 99%. And also I noticed that it's battery health dropped one after every week. Toady is 17/1/2024 and battery health of my iPhone is 96%.Not even 2 months have passed yet. I am not a heavy user of my iPhone, I chared my iPhone 20%-85% every day at same time and i dont play any games by using this. Please tell me is this is a softwear problem or hardware problem (battery issue). How can i fix this issue? Is this a normal situation?

I had the same issue in the first month 2% dropped,and now i updated it to ios 17 and in this month 2% dropped down i am at 94% and this is the 11 month since i have the phone thanks apple

Same as me I got the 14 base model around october it comes with ios 16 then later I updated to ios 17, and ever since I updated to ios 17 my battery health keeps dropping when I use fast charging. My phone got really really hot but it keeps charging, no high temperature notif or what so ever. It didn’t pause or stop but it keeps charging and Im losing my mind.(note I use fast charging ever since I got the phone, and every time it got hot it stops or pauses the charge) right now my battery health is 92%

That's normal. Don't stress over it. The average is about a 1% drop per month, but the drop is not linear. You may see a 2-3% drop one month, then not see a drop at all for 3-4 months.

For me I got my IPhone 14 base model in October 2023. My Battery Health says 100% still but the battery has been going down much faster than before. This was written in March 2024.

I don't see any problem per se. There's no guarantee of how fast it declines. All Apple provides is a one-size fits all nominal rating of 80% after 500 cycles. But some batteries do better than that while others don't, and there are just way too many variables including just random things that the user can't control. Batteries are the weak point in many portable electronics, but they can be replaced for far less than the cost of a new device.

I get that you've probably seen some advice that suggests doing things to improve the overall battery longevity, but a lot of that is impractical or possibly even counter to what might actually improve overall battery longevity. Using it while it's charging (or at least connected to power) is not detrimental for overall battery longevity. It might even be better because it means that the battery generally isn't being used - such as when it stops charging and basically only draws power from the external power source.

My advice is to carry around a reasonably sized USB power pack. It would extend how long an iPhone can be used and can theoretically prevent cycles from being accumulated.

As described above, that is completely normal.

Apple expects your battery health to drop 1-2% per month of use.

Again, it is NOT abnormal. The drop will not be linear. You may see it drop several points in a short period of time, then level off and not change for months.
