Not really, can expect the F3 to last longer since it is more powerful.
How much longer are you expecting for 10-20% performance difference? 1 additional phone cycle?
When the battery stop holding charges, you probably want to replace it already, cpu + display power usage and battery tech are expected for great improvements in the coming years, so it wouldn't be surprising if phone lasts twice as long or more
Those who buy 128gb knows what they r getting, so very little chance of them maxing out the phone's storage.
You be surprise how many people who don't actually know how to choose what phone to buy. Although I do expect a bit more from those who found out and chooses POCO themselves
I know too many people who brought specific model base on recommendation but cheaped out on the specs (storage/ram), (eg: received link, open product page, chooses cheapest model)
At least recent mid-high phone give reasonable amount of storage like 128gb and not just 64gb
Some end up with like ideally 34gb usable (out of 64gb, keeping 10gb free), of which 30gb is used by whatsapp, facebook, mewatch, qoo10, lazada, shopee and banking app
Every few months they come to me, I move their old stuff over to the sd card, all because they wanted to save $50
So much space is used by whatsapp for some people, they have it set to download every single dumb video people send them (default)
