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.

I bought my Iphone 14 pro last December 2022 and now July 2023 the battery health becomes 95 so fast. Idk what happen. I make sure that I charged my phone before its get down to 30%. I guess its because of the updated then?
On average, batteries will lose about 1% a month. Therefore, 5% in 6+ months is better than average. Nothing is wrong with your phone.
Why are you checking battery health? Are you experiencing other problems with your phone? If you are not, there's no useful information to be gained by checking. Check again about a month before your warranty expires.
I have had my iphone roughly one year and the battery health just now dropped to 99%. It's because I never keep charging the phone when it has reached 100%.
I set an alert on my phone when it reaches 100% and disconnect it immediately. I never charge it overnight and let it sit on the charger when fully charged.
This has worked well for me although I was hoping I could keep that 100% battery health for longer than a year.
You seem to be doing everything right, so I would say that your battery is not performing properly. You can have it checked at a genius bar.
You wait until it reaches 80% then replace the battery.
My iphone 13 battery health went from 100% to 99% after 3 months.
Your battery is doing fantastic. If your battery was average, it should have gone from 100% to 97% after 3 months......as mine has done.
You don't indicate how old your iPhone actually is, but if it is 6 months old at this time, and the Battery Health is 95%, you are still way ahead of the crowd.
You might want to consider sending flowers to Apple for your exceptionally good battery performance.
Battery Health will decline at about 1% a month.
The only way to restore Battery Health to 100% would be to replace the battery with a new battery.
My iPhone XR is still showing Maximum capacity of 95%. It dropped to 95% after three months of use and has been “stuck” there for over 3-1/2 years.
I personally don’t think that can possibly accurate, but what do I know. I’m not a heavy user so I don’t pay that much attention to that number, but I would think it lose some capacity even if it was turned off and put into a drawer and tucked away simply because it is closing in on being 4 years old.
Actually concern here is battery will eventually reach to 80% soon. So ,Comparing it to other Android phone .Apple Battery gets exhaust more early.
And in next coming year or year and half I am very sure my phone will reach to 80%.
I am looking for some solution here...
Hello Apple community, I am a first time apple user and today i saw that my battery health is reduced by 1%, i started using from Aug 1 2022 and today Feb 25 2023 roughly 6+ months I believe the discharge is normal after reading the community posts, I am here open any suggestions about maintaining the battery health.
I have the same issue it was 100 from last July to February and then it went down to 99 then two days after 98 and then one month later 97. I don’t know what’s normal or what’s not but I think the switching between data and wifi causes the fast drop in battery
We charge our phones overnight, every night to 100%. My 14 Pro is currently at 100% capacity after 9 months. My 4 year old XR is at 94% after 4 years. My wife’s 8 is 6 years old. Its battery is 98%. So perhaps your information about what batteries “like” is misguided.
Actually, the Best Practice is to charge overnight, every night, with Optimized Charging enabled and automatic backups also enabled. As Apple recommends.
My granddad used to say It ain’t what you don’t know that hurts you, it is what you know that ain’t so.

I lost only 2% in last 8 months, i think its more than other users iphon13
On average any iPhone will lose about 1% of capacity per month, so after 8 months the average user will see 92%. If you see 98% your phone is doing much better than the average user’s phone.
How long has it been since the phone was new from the factory? Did you buy it new, or is it a previously owned phone that is new to you?
And do you follow best practices for charging, which means charging overnight, every night with Optimized Charging enabled, and never letting it drop below 20%?

I am wondering why my iPhone 13pro battery capacity is suddenly reduced by up to 3 hours the week prior to the iPhone 15 release. Seems like Apple were fined millions for this same battery reduction scam a year or two back?
No, they were not. Apple settled a suit by people who were upset that Apple had not communicated properly why phones were being throttled. Apple was throttling the processors on phones with failing batteries so that the phones didn't shut down precipitously.
Maximum battery capacity is not measured in hours but in percent. If you go to Settings>Battery>Battery Health you can see your battery's maximum capacity. If is 80% or less, you need a new battery.

Mine after 5 months of use. I just noticed today that my battery health dropped 1%. Never played any games and install such.
You are seeing perfectly normal battery aging. Actually, you're doing better than average. One percent a month is average and you've gone 5 months and only dropped 1%. Fantastic!
