Battery Issues with Redmi Note 10 Pro - Should I Replace the Battery or Get a New Phone?

I've been using the Redmi Note 10 Pro for the past 2-3 years and have never encountered any major problems with it. I'm a very light user, don't play games on my phone, and always keep the display set to 60Hz.

Recently, I've noticed that the battery is draining rapidly. It can drain completely in just one hour, and I've tried everything to fix it. Once, after rebooting, the battery level dropped from 77% to 1%.

I really love this phone, and aside from the battery issue, it's perfect for me. Should I replace the battery, or is it time to get a new phone? I'd appreciate any advice or experiences you might have!
