My iphone 13 battery health went from 100% to 99% after 3 months. Since last September 20 when I update to ios 16, my battery health is decreasing. Battery health has decreased by 4% in the last 20 days. Solve this problem?

September end last last year.
iPhone battery capacity drops an average of 1% per month. So it has been 8 months. Thus 93% is about where it should be.
Batteries are consumables; they lose a little capacity every time they are discharged, then recharged. On average this works out to about a 1% loss for every 25 “full charge cycles”. As one example, if you charge the phone overnight, every night (and that is what you should do; it is a best practice), it starts the day at 100%. If it drops to 20% by the end of the day before you charge it again overnight that counts as 0.8 full charge cycles (20% to 100%), or about 24 full charge cycles per month of use. For this example your battery capacity will lose about 1% per month. Of course, if the end-of-day level is higher than 20% the capacity loss will be a little less, and if it is lower than 20%, or you charge it during the day, the capacity loss will be higher.
Once the capacity drops below 80%, or if there is a message in Battery Health that the battery is not meeting peak performance expectations, it’s time to change the battery→iPhone Battery Replacement - Official Apple Support
The absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates. Here's more information→About Optimized Battery Charging on your iPhone - Apple Support
I put my phone on a charger literally any time it's not in my hand and have roughly the same battery health.
The phone charges intelligently, there's no need to jump through hoops.
I'd be more concerned your battery was not properly reporting its health if it was at 100% after a year.
I will simply add that the typical Apple Battery lasts about 2 years of normal usage. So yours is doing very well!
The solution is to replace the battery when it reaches 80%. No other solution exists.
Iphone 13 has not been out for two years, your “assessment” is pure fantasy.
Don’t worry, its way better than some other user,
its normal to reduct 1% in 6 month
i also buy in September and same my phone battery also 99%
My iPhone 13 pro’s battery health went from 100% to 97% in 42 days. Is this normal?
Ah, that changes things. After 290 full charge cycles an average phone would be at 88%, so your phone is doing better than average. You must be a very heavy user.
A drop of 1-2% per month of use is expected and normal.
A drop of 1-2% per month of use is completely normal and expected.
If you feel you got scammed, then take it back for a refund. Otherwise wait until it reaches 80% then get the battery replaced.
In last 2 months my battery health went from 100 to 93. It went from 95 to 94 in a week and then 94 to 93 in 2 days. We are being told that until its above 80% its fine. But the problem is that the rate at which it is declining, it won’t even be a year and it will be below 80%. That too when background refresh and notification are off for majority of apps, don’t play any games on it and also don’t have any social media except for whatsapp and linkedin. The most I do with the phone is spotify.

After roughly 3 months of usage the battery in my iphone 13 has been doing well and it is still at 100%.
Glad to hear it! What that probably means is that your battery’s maximum capacity started above 100%, but this screen doesn’t go higher than 100%. If you have a Mac the app Coconut Battery for Mac can tell you the actual maximum capacity.
I have an iPhone 13 I got on December 5, 2022 The battery health says 97%. I hope that’s normal. It was just a month ago that the battery health said 98% within the last month. It went from 98% to 97% the battery health is that normal. I understand the battery health is gonna go down for within a month it went from 98% to 97. I’ve only had the iPhone 13 brand new since December 5, 2022. I don’t think I was expecting before summer to already have the battery health be 97%. And I get it people are telling me. Oh it’s healthy. It’s fine but like I have this weird feeling that I won’t even have a phone a year like by December 2023 I wouldn’t be surprised if it gets down to like in the 80s. But within a month, it shouldn’t have gone down that much but I don’t know.
Well, I’ve had my iPhone 13 since December 2022 and its battery health is already at 97%. And just last month it was at 98. And today I looked and the battery health says 97%. I guess I wasn’t expecting before summer because we’re not at summer yet that it would already be at 97% the battery health I don’t know if that’s a good thing or not I came from an iPhone eight that had really bad battery. That’s why I got the iPhone 13 because my iPhone eight was at 80% battery health and would last maybe two hours on a good day I could maybe get 3 to 4 hours out of it. It was usually anywhere from 2 to 3 hours. It just didn’t last very long. My iPhone 8 I felt like I was charging it way too much. So then I got the iPhone 13 and December. Well I was expecting way later on mid 2023 before it ever got to where it is. So I’m hoping that there’s nothing wrong with my battery on my iPhone 13 because as I mentioned it was Botton December and it’s already at 97% battery for health and it’s only been at 98% battery health for a month before it went down to 97. I don’t know what I’m doing wrong. An apple just said oh well it’s still in the 90s so it’s still good battery health. But like I don’t want to get to the end of this year and I have to replace the battery like it should at least last a year before I have to replace the battery but I have some weird feeling I might be replacing it at the end of this year I don’t know.
