X3 NFC still going strong since 2020

Not an ad, but I bought my X3 NFC four and half years ago.

It's my main phone and 4 cases, 3 screen protectors and 1 charging cable later it is still going strong, lasting between 24 and 36 hours and generally being very usable.

Cons:

• the thumbprint reader on the side isn't always reliable
• there some ads and stubborn bloatware that I had to get rid of
• some random restarts a few times per year
• a bit too big for one hand use

I want a new phone, most likely the X7 Pro, but I cannot justify while my old one still works as well as it does.

When your Poco phone started to go, what were the signs?
