I'm tempted to upgrade for:

• Wireless charging
• 5G

But I'm not that tempted so I haven't done it, still very happy with my Oneplus 7T from 2020.

I have been using same phone for 5 years now. Never visited to service center. Always used cover & screen protector. I usually see two strategies either buy very cheap phone and keep upgrading in 2 year or buy a mid-range use it for 5-10 year before upgrading. There is usually no significant upgrade in tech in 1 year but wait for 5 and you will feel you are actually getting something new and better

You do it to give Samsung or Motorola or Google or apple or Amazon your money every year, obviously

My Galaxy S8 had a lot of annoying problems both on stock ROM and Lineage OS. After three years I switched to Zenfone 8 and so far I am satisfied. The battery life is crap though, especially after updating to Android 13. I'm considering a downgrade if it's even possible

I upgrade when the opsys gets hopelessly outdated (as in apps no longer supporting it) or the device physically breaks. My last phone (Huawei Ascend P7) lasted for 7 years, but the Android 4.4 got just a bit too old, plus I cracked the screen a month after removing the battered to hell glass screen protector...

I don't care much about the phone not getting OS updates since I don't keep anything important on a phone in the first place and I don't care much about CPU/GPU performance since I don't run intensive apps on my phone—that's what my desktop and server are for. My current phone I bought last year will last probably for 5 more years.
