Manufacturers don’t make displays under 6 inches available for purchase, with special cases (such as the iPhone Mini) being made under exclusive contracts. The best lead they have so far is to try to use displays designed for the front part of a foldable phone, but they’re yet to strike an agreement.
TIL that display manufacturers are also part of the reason why we aren’t getting small phones and why it’s probably even harder for manufacturers like Fairphone to make them.
75% of your battery cycle, the screen is off. So a smaller screen can only win battery in that 25% window. A bigger battery on the other hand can be applied to 100% of the cycle.
Unless you go oldschool lcd, a smaller screen does not gain as much as a bigger battery for battery cycle time.
My Sony Xperia XZ1 Compact had very excellent battery life for it’s small battery. Sony definitely did an amazing job optimising it.
However, the 25% on-time use a lot more than 25% battery.
