iPhone Battery Health at 83% - When do I replace it?

It's getting close, you will want to replace it withing the next few months.

Batteries degrade over time with usage due to chemical aging, that's just how they work.

You can expect about a 1% drop per month with average use on an iPhone.

Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.

You can replace your iPhone battery once it reached 80%, but if it’s worth to replace battery or not? It depends, as the software updates, its load on device increases, so battery and all device’s components have to work hard to meet that load which reduces maximum capacity of battery quickly. For example, I have an iPhone 11 which was released with iOS 13 and device was Able to keep up with software load, but now it’s iOS 17 and iOS 18 is coming soon, so they are more heavier for system. Even though device is compatible for iOS 17 or 18 but still device’s components work hard and battery automatically works hard to meet those demands so it’s affects it’s battery life. This was explained to me by an apple support advisor.

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.

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.

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.

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.

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.

My IPhone 13 Pro Max battery is at 85%

after 2 years should I replace it

To quote from the post that immediately proceeded yours by Bob Timmons:

Apple recommends replacement at 80%, so you have a few more months to go.

If the battery is still working well at 80%, you can probably go another month or two beyond 80% before replacement.

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.

If you find it isn't lasting you long enough especially, you should replace the battery now. Apple classifies 80% health or over to be healthy, so it would be advisable to replace at 80% if not now.

But I would also strongly recommend getting the battery replaced by apple as third-party options could be risky or just not last as long.

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%

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.

My iPhone Xs battery health is 81%. Do i replace it now?

You can contact Apple and have them run a diagnostic. Their tests are more accurate than the indicator on the phone. It's possible that their tests will show that it's 80% and/or they may be willing to do it at 81%. I had mine replaced at 81% because I was also starting to see random shutdowns and they took that into consideration.
