Call disconnect

82% is not very healthy and could be the reason for the call drops / disconnects – because the antenna of your iPhone requires sufficient power to maintain a connection with cell tower signals. Apple recommends having the battery replaced at around 80%. The maximum capacity % is only an algorithmic estimate of a dynamic chemical process – so your capacity could actually be lower than 82%. ...Consider having the weak, aging battery replaced:

There is no guarantee. However, an authorized technician could run a test on your battery to confirm its health. Alternatively, see if this helps:

Restore your iPhone to factory settings

IPhone 11 (NWM02ZD/A - A2221). Kondycja baterii jest na 82%.

I contacted the operator on his side is all ok. I noticed that a lot of people are reporting the same problem looks like a software error. I even did a system restore via itunes before updating. I recently reset all settings as well as operator settings. nothing helps.

It's a little strange. That is, making a call puts more strain on the phone than using the internet package and, for example, using YT. What is the guarantee that after replacing the battery everything will be ok since the colleague above has the same problem and his battery level is 86%.

Here the same... After 1-5 minutes the speeker mode activated, and after it, the call dropped.

Iphone 11, battery 91%

I think it's from 16.4.1 softver upgrade...

After install 16.5, nothong changed, calls dropped randomly.

I changed my SIM card, because it is 5 year old, but nothing happend.

It is so frustrating.

I dont wan't reset the phone because in the last 3 year make a lot of config properties changes...

I think it is a software bug. Lot of iphone 11 users have the same problem...

If you only hear through speakerphone mode --> If your iPhone is stuck in headphone mode - Apple Support

Restore your iPhone to factory settings - I made about a week ago before the release of the ios 16.5 update.

I am still convinced that the software is to blame.

akshtasuri ~ Does your iPhone 11 still have its original battery?

And what's the Maximum Capacity % here?...

Settings > Battery > Battery Health

86% is unexpectedly high for an iPhone 11 original battery, but assuming that % isn't stuck, the battery can be ruled out as the cause.

I have the same problem. Is there any advice for this? Even the latest 16.5 update did not help. The device does not perform its primary function. I have been struggling with this for 3 months.
