Can second the replaceable batteries and extendable storage.
However I don't mind the lack of a headphone jack, because they make affordable dongle dacs now. I think instead of a headphone jack phones should just have 2 usb c ports
Dacs are great, I have one for my IEMs and love it. But only when im sitting. As soon as any movement happens I am occasionally punished when the cable moves 1mm out of its port with noise or complete sound stoppage. I can use my TWS but sound quality and reliability suffers.
Replacement batteries should be a legal requirement. My 5 year old android phone needed a new battery and people kept telling me to get a new one as the phone is old anyway. It still does what I need so why should I get a new one just because of a battery.
I ended up taking the phone apart myself and replacing it. Wasn't easy and took me over 2 hours.
I'm up for anything which keeps phones working for longer. Such a waste of money and resources for what should be a simple job.
To be fair, expandable storage as we've had it sucks. MicroSD cards cause a lot of issues, and a good chunk of Android apps block the ability to use them. Connecting an SSD to your phone is a much better experience.
