I have i phone 13 pro may battery helth showing 99% after 1 and half month (45 days) uses. It that any issue?

No, it's not an issue. The average decline in battery health is about 1% a month.

Several my friends have iPhone 13 Pro Max 256gb from 11 months with 99%:

How can be explain this?

It is not 1% for every month.

Basically a lot of people are tired to accept that this situation is normal:

It is not normal.

Infact I check regularly the battery circles using iMazing on my Mac or Win.

As I have no personal knowledge of these people or their phones, I cannot comment. What I can tell you is that I worked for Verizon Wireless (major U.S. carrier) for 20 years, part of that running a service department. I've looked at more phones than you every will. It's normal. What you allege your friends are seeing is not normal.

It is not 1% for every month.

Please look up the statistical concept of "average"

Basically a lot of people are tired to accept that this situation is normal:

Basically, a lot of people what batteries not to be consumables. They become obsessed with "managing" the health of their batteries.

It is not normal.

Again, yes, it is.

Infact I check regularly the battery circles using iMazing on my Mac or Win.

So?

""""""""""""""""""""" So: """"""""""""""""""""""

1) Before a person can tell that the battery is perfect he should at least know how many charge cycles the battery has;

2) It is normal for the batteries to wear out: there is no need to repeat it;

3) The new iPhone batteries never have 100% charge but more ... +/- 101%, 102%, 103% testing with a dedicated battery testing tool or with software like iMazing or Coconutbattery: same results;

4) I had previously posted that my iPhone 13 Pro Max had shown a 96% battery health but in actuality was 103% health checked with a dedicated battery testing tool or with software like iMazing or Coconutbattery;

5) The battery health of my iPhone 13 Pro Max had reached:

- 99% after the first 25 charge cycles

- Then 98% after another 5 charge cycles

- Then 97% after another 5 charge cycles

- Then 96% after another 5 charge cycles

And now after several weeks is stable at 96% and in the next few days I will post the actual cycles using a battery testing tool and iMazing;

6) we disassembled a lot of batteries and tested with a dedicated battery tool and the state of health was 102%, 103%.

7) iPhone 11 Pro and iPhone 11 pro max had the same battery health problem and received an update to recalibrate the battery health.

8) Several iPhone 13 Pro Max after 1 year still have 100% battery health (is this clear?):

so it is not true that (as some person continue to say) the average decline in battery health is about 1% a month.

And to prove this, just need to search in several very technical online platforms (videos);

Also: Some batteries can be defective and others can be perfect: for sure mine is defective;

9) I never wrote that we have taken apart and repaired more phones than a person might have in his life...ehm...for sure;

Bro when i bought the phone battery health is at 97% and after 25 day of normal use it came to 96% and just after 6 days it came to 95% !

and 3 months 11 days warranty remaining means phone is used 8months n 20 days

bruh but some of friends have the same model (13 pro max) and they’re still at 99-100 :/ they use fast charger and I never use a fast charger I am using 5w ! Can u pls tell me 5w is good for battery health or faster 20w

No bruh I agree with you ! And thank you for the advice em never gonna check my battery health again :) but bruh I have just 4 apps in my phone instagram, snapchat,facebook and VPN !

burh just have 50 contacts in my phone and no one call me :(( call receiving ratio is 0% and and brightness is always at 0

You're still overthinking it. Follow the instructions in the article I linked to and don't worry so much. ;-)

And, by the way, my name is not "bruh".

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%.

I got my 13 Pro Max back in October… 6 months later and it’s still at 100%

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%.

How do you use 5w charger for 4800mah iphone 13 pro max?

it almost takes 5hours to charge it completely

As noted, charge your phone overnight.
