How to Charge Your Phone Without Destroying the Battery Over Time
Most phone batteries don't fail dramatically. They just hold a little less charge than they used to, then a little less than that, until the device that lasted all day barely makes it to afternoon, and you start carrying a charger everywhere as a matter of survival. That decline is partly inevitable -- lithium-ion cells have a finite number of charge cycles, and capacity loss is built into the chemistry. But the rate of decline varies considerably depending on charging behavior, and most people's habits are accelerating the process without knowing it.
Age is part of it, sure, but the overnight charginghabit accelerates the process considerably. Lithium-ion batteries lose capacity faster when they spend extended time at the top of their charge range, which is precisely where an overnight charge leaves them. The fix doesn't require a new phone or even a new charger. It requires a small adjustment...
