I really do hope they'll make a smaller and lighter phone.
According to https://specs-tech.com/en/fairphone-5/ this weights 220 grams. It's almost twice of what I deemed to be a reasonable limit for a phone.
It's comparable to the Pixel 7 Pro (212g) or iPhone 14 Pro (206g), but it would be nice to see that number trend downwards. I had a Pixel 4a in the past, and that seemed like a good balance between size and weight.
I feel like a lot of the issue is because the new operating systems are a lot more power intensive and Google play services is always doing so much in the background, you need a super heavy battery just to get an all day battery life whereas older phones could get the same battery life with a lighter/smaller battery and less OS bloat.
