I’m not convinced that the SD 7s3 is worth the extra cost. I had a 765g-powered Mi 10 youth edition with a 5x periscope which was cool.
The CMF1 with the MTK D7200 is a battery miser, which I greatly appreciate and often get more than 10h SOT between 100% and 15%. And the performance is still quite good.
I would NOT want to pay £20-50 more for a phone £169/£199 to £219/249 for that processor.

I had a 5x periscope on my last phone and would pay £50 pounds more for that option.
I just don’t find the value proposition of the (a) series phones compelling.
Especially, if the 3(a) starts at £399 or so.
