Started using it in April and already lost 1% battery capacity.
Is this acceptable?

I know it can few a little disappointing, but there are a lot of variables that would explain it. We can’t really tell anything, and the battery health percentage only shows part of the picture. I would say to check on it once every few months, and see if it is stable, or if it drops quickly.
 
I don’t know what the battery health percentages are on my devices. I’ll have to look them up.

Edit: My year and a bit old MacBook Pro is at 91% and is perfectly fine. I can still get a day's work on battery.
My iPhone 14 is at 84% and is still ok, but sometimes I need to top it up in the afternoon (or I did until I broke the screen and it was relegated to backup)
My iPhone 11 is at 76% and needs a top up to make it through most days.
My iPad Air 2 doesn't say, but it isn't good, it's hardly usable on battery at all. If I'm going to use it for more than 15 minutes, I plug it in.

You just didn't see the numbers before. Try installing Coconut or iMazing on your computer to check battery health on your iPad mini.

My launch day iPad mini 6 is currently at 87% battery health.
Actually do not care about the mini any longer. The 1% loss in 2 months time on the new iPad Air concerns me.
 
I don’t think that is anything out of the normal for these batteries. If you set the max to 80%, it will help a lot. I have a 2024 Air that gets daily use. Started using it in March 2024 (or whatever the launch month was). 370 cycles later, it’s still at 100% capacity.

Edit: it’s at 97%. Sorry, I hadn’t checked in a while.
 
pardon me , but how good is the estimate , i.e. what is the uncertainty - I truly detest estimates where they are given or accepted as exact even that are in effect guesses based on certain assumptions (maybe very good guesses but guesses just the same)

Are you using Coconut Battery or the internal settings indicator? There is usually some variability in Coconut Battery readings.
 
Making battery percentage visible to the consumer is one of the worst things Apple could have done. It creates a lot of unnecessary obsession and FUD.
yeah but it's awesome for the resale market. notice almost every listing on FB of an iPhone/iPad includes a picture of the battery health.

to OP's point.. get over it. your consumable item is at 99% integrity after being used for almost 2 months. people say 80% is when health is noticeably degraded (for a phone's small battery), so you have at the very least 38 months of consistent usage (in your case greater than one full cycle per day) until you reach that point.
 
My opinion is just an opinion, but I think Apple had better batteries in the past than now. You are not the first one to notice this weird battery behavior, it ages much faster and devices overheat much easier than they used to. It is more relevant to iPhones tho, but if you notice a percent dropping each month and by the end of the year you get something like 88-92% - go to Apple service and tell them device might be defective.

If you already notice weird behavior (overheating, faster battery drain than they claim) you can already give Apple a visit.

After all, if it is “normal” to lose 10% of battery life every year. Doesn’t it mean that device’s effective life will end in just two years and a half?
This doesn’t compare at all to my iPad Air 2. While I don’t use it nowadays, it still works and has enough battery to watch one big movie. Device was released in 2014. In 2019 it still had enough juice to watch 3 full movies each 2 hour long
