iPhone 13 Battery Health Drop

Something similar happened to me, I had 100% on my iPhone and I had been using it for approximately 4 months, then it went down to 99% and it stayed there for about a week, then it went down to 98, the next day it went down to 97 and today it's at 96. I don't know if it's something bad or not. It is simply updating with the true value of my iPhone. How does the battery behave after this?

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!

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.

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 couldn't agree with your post more. I've always done the same. My batteries generally last about two and a half to three years. The only times I pay much attention to the battery health number is when the phone is close to the end of its warranty (just in case) and then only if I notice a decrease in performance.

Batteries are too cheap (compared to the price of a phone) to worry about micromanaging them.

That's insanely good; normal for your battery at this age should be 64% or less and you should have already needed to replace it at least once, as it's generally advised to have it replaced when it falls below 80%.

My iPhone 13 which I got on February 5th, 2024 brand new, went from 100% to 94% today, it drops after two charges, I’m so frustrated. It’s not even up to a month.

Bought brand new from whom exactly?

Then you don't know how long that phone had been sitting on a shelf not being charged. iPhone 13 was released in 2021, almost 3 years ago. If that phone sat around not being charged, its battery health was already degraded by the time you got it. Lithium iON Batteries which are not charged for extended periods of time lose battery health.

Let's see what it shows for warranty, by going to Settings > General > About and look at the box under Serial Number. Tap it and if my assumption is correct, the phone's warranty may have already expired. iPhone warranty begins the day an iPhone leaves Apple or an actual Apple Authorized Reseller. A gadget shop is not an authorized reseller.

I got mine for almost 8 months and not a single % of health drop. I suspect it might be because I use my Apple battery pack as a wireless charger. It “drips” juice cleverly in orde to safe battery health so it might make that difference.

Went to Apple Store in South Coast Plaza in Costa Mesa here in California, somebody checked my battery and was told it’s ok. They couldn’t check further because I did not have the space-a.k.a I did not subscribe to I cloud.

Now my battery reads 80 percent but got a warning that my battery is low at 10. How can this be? It’s not about the i cloud issue, it’s about the battery draining too fast. Hey Apple, are you even listening?

Checking your battery has nothing to do with subscribing to iCloud. However, if you didn't have enough free space on your phone (something that would not be remedied by subscribing to iCloud), that could cause a problem.

No, Apple is not listening here. This is a user-to-user forum. Apple's participation here is largely limited to making sure we stick to the rules.

I bought my phone a month ago (not brand new) it was at 97% health , Now it‘s at 91% i‘m concerned i got scammed , i‘m following apples instrucitions on how to keep battery health at best but it‘s dropping in matters of days. What do i do

what battery health percentage is it at now?? i noticed a drop like 6% in a month like i dont even use my phone on charging same as you background off and dont excessive charge it im at 80 now so like idk bro? what do i do now i bought a used phone but like it was in good condition

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.
