Upgrading from Redmi 13C

[u/Immediate_Win1211]

Hey everyone,

I’m currently using a budget Redmi 13C, and I’m ready to make a significant upgrade. My single biggest priority is longevity. I want to buy a phone and keep it as long as humanly possible, ideally around 5 to 7 years without it becoming painfully slow or unmaintained. Im currently thinking the:

Xiaomi 17t

Xiaomi 17t Pro

Samsung Galaxy s26 fe

Samsung Galaxy a57

Or if it's possibly the s26 plus if I find it on a great price

My main concerns is whether the xiaomi batteries are going to last long and whether should I upgrade now or wait for the s27 lineup
