why my laptop battery will take an hour to reach 90% but then take another hour to cap to 100%
ELI5 Option (this is off my vague understanding, might be incorrect). Imagine a battery is like a cup, and your charging source is a fat pitcher of water. When you first start pouring the water, the cup is empty so you dump it all in there because well, it's nearly empty and easy to control.
The Short Answer
ELI5 Option (this is off my vague understanding, might be incorrect). Imagine a battery is like a cup, and your charging source is a fat pitcher of water. When you first start pouring the water, the cup is empty so you dump it all in there because well, it's nearly empty and easy to control. As you get near the top though the amount of water could easily cause you to spill. That's bad, so instead towards the end you start to pour it slowly to get it topped off just right. It takes longer but it's safer. In other words, overcharging a battery is bad. It can wear out the cell or cause failure. Your charger or battery usually contains circuits that senses near when this is going to happen. So the charge mode switches from a 'dump' charge to a 'trickle' charge. Then once it gets near full it bumps off/on letting the charge sort of hover. So your batteries never 'really' get full, but it's for your own good. That's what happens to the best of my knowledge.
