Your battery probably needs to be replaced. In the U.S., it would cost your $89 dollars. It's probably similar in Canada:

Unless you're planning on getting a new iPhone with in the next couple of months, I'd say it's worth replacing the battery.

Batteries, like people are individuals. No two people age exactly the same and batteries don’t age the same either. The exact usage, chemical make, storage conditions, exposure to heat and cold and about a dozen other factors mean that every battery ages differently. Battery aging is not a linear (straight line) and degrades at different rates as the chemicals in the battery age and the other factors mentioned above. Apple expects your battery health to be at 80% after 24 months. If your battery health misses that expectation, contact Apple Support.

There is not a point where you must replace your battery (unless of course it is bulging), if it is 83% but still lasts you how long you need it to it is fine. Apple recommend replacement under 80%, but it isn’t necessary.

I've always wondered why this is the case; why wouldn't apple want to replace the battery over 80%? Surely if the customer doesn't find it lasts long enough especially on smaller models like the 12 mini or SE.. And it is extra business for them, no?

Probably because replacing a battery that didn't really need replacing wouldn't end in a good customer experience. It probably wouldn't solve whatever problem the customer thinks they have (lots of people think they have a battery problem when they don't). It also probably would be cost-effective. I suspect Apple doesn't make a lot of money on replacing batteries between the cost of the battery, the labor, and the disposition of the used battery.

Apple will replace a battery that has more than 80% capacity if diagnostics show that there is something else wrong with the battery. I had one replaced at about 83%. The phone was shutting down suddenly. Apple ran diagnostics and decided the solution was a new battery.

But, as Bob said, only Apple would really be able to answer that.

Original batteries have a much longer life than non-original batteries, and opening and closing the mobile phone may cause other failures and reduce its efficiency.

So it is better to continue with the same battery until 78% and if you need to charge, use a power bank

but it would be nice to have an official "sub 80%" reading from the phone, so i know that i won't get denied if i take it in.

Apple can run diagnostics remotely. While it is certainly common that capacity drains more slowly later in the battery's life than it did early on, there may also be something else wrong with your battery (or phone). Contact Apple and see what they tell you.

The last battery I had replaced showed as 81% on the phone but I was also experiencing sudden, random shutdowns.

If you find it isn't lasting you long enough especially, you should replace the battery now

Apple will not replace the battery unless it tests out as defective or is under 80% Maximum Capacity.

Sounds really good. Could be 80% after 500 cycles.

Iphone battery 90% and cycles of charging 935 times. Is my battery original and good conditions?

That is amazing. Your battery may be a one of a kind.

Send flowers to Apple.

You are worrying needlessly about the battery. Remember, it is just a battery. It will decline.

Replace the battery when Battery Health is down to 80%

LOL you're right, I was ranting and venting when in a poor mood, not acceptable to do in public :) and I should have them test it. and of course i did that after saying I'd had 30 years of great apple experience. now that i think about that, that's buffoonery (sp?) and if a moderator is reading this, you can delete my original post, or if I can figure out how to I will.

In a month or two when it is down to 80%.

Apple generally will not replace the battery unless it is down to 80%, but if you have an authorized Apple service shop nearby, you could ask them about replacing now.

I am currently using a iPhone 12 which battery life is at 75% now someone I know is selling a iPhone 13 Pro Max for $400 with a 83% battery life. Is that worth doing knowing I will soon have to change the battery because for all of that I could just keep the phone I have. Change this battery and or wait to get a brand new more recent iPhone.

Only you can answer if that makes sense to you. I would point out that whether you keep your old phone or buy one with a battery with 83% capacity, you need to budget for a new battery. If the iPhone 12 still works and you don't have a lot of money, replace the battery. If the $489 the newer phone is going to cost you is within your budget, sell the iPhone 12 for whatever you can get for it and put that toward the newer phone.

Yes, you should replace your battery whenever your iPhone begins to experience delays, overheating and overall performance is suffering.

Apple will only replace the battery if 1) it's under 80% capacity or 2) they can diagnose other issues.
