Among the current models the Samsung Galaxy S23 and Asus Zenphone 10 seem to be the best options when size matters.

Both are similar in volume, but the ZP10 is less wide while the S23 is quite a bit slimmer.

Advantages ZP10:

• Larger Battery
• No Samsung Bloatware
• Slightly more pocketable

Advantages S23:

• bigger Display
• better Cameras

I went for the S23 because I think you get more phone for the size.

It is but the mod does not allow questions there.
