So, I like a lot of things about the BV9800 but I've never had such a big and heavy phone before (having a Sony Z5 Compact right now) and I'm not quite sure how I feel about it. To get a bit of a feeling about how it would be to hold and to carry around all day I designed a dummy that can hold 10 AA batteries to get close to the actual weight, I got to 300 g of the roughly 320 g the phone actually weight. Close enough for me.

I shimmed the batteries with some paper to lessen the rattle and covered them with clear packing tape to lock them in place.

For anyone curious what could make a phone weighing almost 1/3 kilo interesting to me:
