Explaining the Galaxy Note 10’s Fast Charging issues
I’m fascinated by batteries. The very idea of a battery is interesting: this silent, static object that holds within it power, electricity — light, movement, energy. Batteries, especially rechargeable ones, are fascinating because they are both simple — stored energy released as components need them, and then filled back up through another source — and incredibly complex. The very makeup of today’s modern lithium-ion battery is something to behold, and requires a considerable amount of engineering prowess to install safely into a product like a phone.
I’m thinking about batteries this week because of the Galaxy Note 10+, which is the first phone to use the burgeoning and increasingly widely-used USB-PD standard to hit peak charging speeds of 45 watts. To most people, the size of a battery matters more than the speed at which it recharges, but capacity is just one of the three pillars that makes up one’s smartphone uptime experience, the other two being discharge rate (the rate at which the components and the operating system consume energy), and recharge rate (the speed at which the battery can fill up again).
