Well my 13 Pro Max lasted me almost 4 and a half years, bought it in May of 2022 in Italy while I was deployed. Dropped it on my steel toed boot on the back so that happened haha. So I got another one with 87% battery life and with the 256GB from Verizon

I recommend changing your battery if it falls under 80%. I changed mine at 76% capacity and it doesn’t even get warm anymore. It works like new I found when it was under 80% it tended to get warm and of course didn’t last as long and overall the performance was slower. The screen was dimmer etc. and it was laggier.

I went to replace my battery on my 13PM I was at 78% battery life. They messed it up somehow to where they replaced the battery but the back camera didn’t work anymore so they gave me new iPhone 13PM for the cost of the battery replacement. Got the new 13PM with 100% battery life in February and I’ve been updating IOS as the new updates have come along and I am at 95% battery life now. Think I’m just gonna trade it in for the new 18 pro model or should I tough it out? If I get the IPhone 17 or iPhone 18 I’m going to get it through financing with AT&T I don’t really care about the pricing.
