Amazing to see everything shrink (except for the battery). Reminds me of a quote referencing Blackberry falling behind the iPhone: "Imagine their surprise when they disassembled an iPhone for the first time and found that the phone was battery with a tiny logic board strapped to it."

- joering2 9y agoThe new concept seems to be dual-battery. I'm sure they investigated designing simply L-shaped battery but for some reason they decided to go with two batteries instead. I wonder if its because one is supplying power to some critical circuits while other one isn't, or since display and battery are #1s replacement on these phones, they simply run some stats and decided that splitting cells into two separate battery boxes will help them cut the costs down the line when it will come to battery replacement.
- Qworg 9y agoManufacturing costs are the most likely reason. Prismatic cells are much less costly to produce in a rectangular format vs. an L shape.
- joering2 9y agoI don't know, but putting 4 cells into one box, versus 2 cells in 2 boxes at the iPhone scale might be more expensive. My take is that still less expensive that constant replacement (warranty, recalls) that they do on daily basis.
- snewk 9y agoit could be related to power draw inconsistencies in cells with concave angles
- kevinchen 9y agoAlong with the reasons others mentioned, 2 cells means higher voltage, so the battery can deliver the same power using less current.
