But now you have to deal with how miserable a 6 plus would be to use in 2023 lol. That phone was slow within a year or 2 of owning it. I’m sure the battery you put in is worth more than the phone itself
My current primary phone is an 11 Pro Max.
My secondary phone is a 6S Plus. It has it's own line, basically I use it on walks or when I could damage my 11PM.
Third phone is a Pixel 3a XL, the phone I had in between the 6s Plus and the 11 Pro Max.
Fourth on the list would be the 6 Plus, the subject of this thread. I'm basically using it as a music streamer at the moment.
All four phones are unlocked but I use my 11 Pro Max as my main phone.
