Why would you see the benefit to upgrading when you just upgraded to the previous model? That's an unreasonable expectation. That would be like complaining that the 2025 Toyota Camry isn't good enough to upgrade to from your 2024 model. Of course it's not! I also really don't understand what the hangup is with the batteries. You bought a $1000 phone, $99 to get a new battery is reasonable. I get it, the cost should be $20 and it shoulde be an easy DIY job, but it seems like you're actively refusing the solution. You undoubtedly spent more to upgrade to the 15 Pro than to replace the battery in your 13 Pro.
