There are common problems with removable battery phone, first it cannot be thinner, second it happens all the time people use counterfeit removable batteries and they explode. Third, they can't make it water proof.
I couldn't remember when was the last time I swap my Note2 secondary battery.
As many phone makers are offering quick charge or 9v charger, and Chinese roms are getting more efficient in some points. Nah, people could live without a removable battery.

Give me a break. Battery is important aspect for them? Not quite. I wouldn't buy their phone exactly because of their batteries. Low-mid range have ridiculously small batteries and high end have non-removable batteries (So even if it lasts a day, it will only be for a year or so, then it still won't be enough).
