That’s pretty good… Mine is at 90% after 10mths.. so average about 1% every 2weeks.

That math doesn't make sense. If your battery capacity is down by 10% after 10 months, that means an average of 1% a month.

update phone system..then see results

13 pro max battery showing 99% after two month

That is very good performance. Congrats on your good luck.

My iPhone 13 pro max is at 89% battery health after 4.5 months. I do use the wireless charger dock at night. This may have something to do with the quick battery degradation. I’m on the iPhone forever plan so I get a new one every year. I’m not too worried about the battery health since I’ll get a new one in September. I can tell that the battery doesn’t last quite last as long now.

I contacted apple tech support and they ran a remote diagnostic on my phone. They said that since the battery is above 80% health that it doesn’t qualify for a repair. “The battery is a consumable item etc” I explained that I’ve never seen one drop so quickly. The rep said they couldn’t do anything at this point.

three months ago I did an upgrade from iPhone XR to iPhone 12 Pro and the battery health from the previous iPhone it’s still in 92% with three years of using what I did to preserve my iPhone’s battery condition ? Well since day one with the iPhone XR I get a apple Smart Battery Case that gives charge to the internal battery and stays in 100% every day and when I need to charge it will charging the Smart Battery Case only so sometimes we need to invest some of money to do things right

So, i think much better to charge it when it drops to 20%

No, there is no scientific reason to wait until it drops below 20%.

No, how you charge it doesn’t have anything to do with it. I use a wireless charger dock every night, and I have for over 3 years. My battery health is 94%. It’s more likely that your battery is defective; after 4.5 months it would be expected to be over 96% in normal use. Use the Contact Support link to have it checked by Apple.

I have an iPhone 13 pro max, it's been exactly 3 months (90 days) since the purchase and now the battery health just came down to 99 percent today. So I guess it's good as compared to the post I read here. I use a 30w anker charger along the original charging cable supplied in the box.

Like I had posted earlier in April, worrying about my sudden fall in battery health to 97% within a span of 15 days, now my battery is still at 97% like it was in April....so like 6 months for my phone since December and 3% drop is good. Strange but now it feels good.

I have 98% 4 months;

Charge cycles: 30 (checked with iMazing on the MacBook Pro);

+/- Always plugged in to charge for the first month;

Always used with Magsafe Battery Pack for the others 3 months.

How many Charge cycles you all have?

Its very strage situation because I have always used the ip X, XS, XR, 11pro with the smart battery case and always I had 100% of battery health at 100% after more than 1 year.

Basically I checked the battery charge using iMazing (and using all the oginal Apple charger and cable) in wifi and I saw that even if connected in charge or to the Magsafe Battery Pack the battery discharge from the level 100% to 94% and then start to recharge again to the level 100% and the discharge (Maybe for not have the battery always in tension I think).

With the iP X, XS, XR, 11 pro it is not so but always at level 100%.

Don’t worry buddy its Just ur phone took time to recalibrate the battery percentage that’s why it dropped suddenly..

Im using 13 pro max as well baught it on 25/12/2021… BH dropped 99% on 15/5/2022

Then 98% on 9/7/2022 Now 97% on 18/8/2022 Battery backup is ok still now don’t know what’s nxt🫤

I feel that the watt for the charger does not affect. Because for my iPhone 13 Pro, I used the 20w charger only and have more apps and all then you. And for slightly more than 1 year, my percentage is at 100%. Only recently, it drops to 97%.
