iPhone 12 Pro Max DO Third Party Wireless Chargers Degrade iPhone Battery?

[Andeddu]

I have a strong suspicion that apple leather case contributed to noticeable battery degradation on my mini 12. Now I got silicon case and it runs cool to touch and feels faster.

So for my mini 13 I got silicone case from the get go. Would I have better chance at preserving battery life by charging it only at night or is it ok to use wireless charger at daytime to prevent battery falling below 20%?

The 12 Mini has a very poor battery which degrades quickly. This is well documented and likely has nothing to do with your old leather case.

I use a silicone case on my 12 Mini and the battery is awful. I have to use a MagSafe battery pack just so I can last the day.
