iPhone smart battery case - Does it actually worsen battery health?

[Boardiesboi]

I just received the smart battery case for my iPhone 11 Pro Max.

Before using it on a daily basis, can those of you who have used past versions of the battery case report back on your current battery health, and how long and often you use the battery case?

I’ve read a few comments that the battery health worsened with sustained use of the battery case.

Just wanted to check with those who have used the case consistently.

Thanks!

I had one on my xs max for its last 5 months of my usage. Battery health is still at 100% before handing down to my son.

I’ve used the XS battery case from day 1. No battery deterioration here at all.

That’s good to know!
Just got mine yesterday and using it today.
Used the phone for a half hour and already down by 10%

Not an unreasonable question considering how ridiculously robust my Pro Max battery is. The only downside is getting into the bad habit of not putting it on the wireless charging stand because I figure 'why bother?'

I do like that camera button. Extra battery is also a +

Do you use the battery case daily?

Do you use the battery case daily?

Yup. But now I’m gonna test how long can it last without it.

Should help if anything since power draws from the case before the phone battery. Never had an issue with it for my XS Max. On the fence still if I want one for my 11 Pro Max.
