Iphone 15 pro and 15 pro max battery problems

I ask me, if the over heating problems for new 15 iphones pro it is the battery ?? Like the samsung note 7 ??? Beautiful phone , but the battery was the big problem !!

If the battery it’s swelling , it is no hardware or software problem , it is bad battery !! I’m sure the chipset for charge and control the charging it is the best. If the battery swelling, end of story, bad “ new “ battery..

i’m thinking to waiting at my iphone 15 pro max natural titanium !!
