The S21 doesn't make sense if the S22 is the same price.
So the decision is the S22 or the S23. Do you feel the S23 is worth almost twice the price?
The S23 pictures and videos are better, but the S22 does just fine if you aren't someone who uses the camera features often. Some people prefer the S22 selfies and colors thought. The S22's battery isn't as good as the S23. The S23 has a much better processor, but will you even notice the difference with your typical usage? Both phones use the same storage controller, the 256gb S23 got the upgraded hardware, so don't expect wildly better in read/write or response between the S22 and S23 128gb.
Thanks! I will be buying from a reseller site so the S23 is 128Gb at that price. The 256Gb one is going for 666€. I don't play any games on the phone and it's mostly an extension of my PC (email, chat, social media) and my actual phone battery lasts like half a day so my expectations are not spoiled lol
My biggest worry is how long I can expect each phone to last. Hoping for 5 years at least.
Samsung supports their phones' software for 5 years, so the S22 has 3 years of support left. My only concern about the lifespan you are hoping for is the battery on the S22. I would factor in the potential cost of a battery replacement in two years in your decision.
