More power to you but there is some questionable stuff in the marketing I'm noticing.
With the industry’s obsession about thinness and “disposable” devices, the majority of phones manufactured in recent years embed the battery as non-replaceable part of the phone, typically soldered directly onto the motherboard.
Nobody solders the battery into the motherboard. That's what's called a really bad idea. Heat + battery = bad. LG recently superglued the battery into the LG G8 so it's pretty unsafe to remove but that's still pretty different from soldering.
Also generally the motherboard is pretty much a separate entity from the battery. My BlackBerry Priv for example basically has the motherboard shaped like the letter C and it sort of goes around the battery and than there's a cable that connects the battery to the board. It has these little pulltabs for removing the battery when needed and the battery sort of rests on the frame of the phone with those adhesive pull tabs I mentioned holding it in place while the motherboard is screwed onto the Frame with T4 screws. The LG G8 also uses a C shaped motherboard.
Basically, it's really hard to take your claims of "having the consumer's best interests at heart" seriously when you're throwing around misleading information like this
This one amuses me as well.
Your user experience will improve as we incrementally add commonly requested applications and features (such as calendaring, notes, calculator, PDF viewer, etc.) while keeping performance in mind
Calendar, notes, and calculators are pretty basic functionality for a smartphone nowadays. Hell, My LG Neon has all 3 of those things and that one isn't even a smartphone.
