Do you charge your devices while you sleep? Why that’s a bad idea...

You’ve probably heard that we are supposed to let our phone or laptop batteries drain down to nothing once in awhile to prolong their life...

While that used to be true - it’s not the case anymore. Older devices had nickel-based batteries but today’s are lithium-ion. These batteries are better off with the occasional shallow discharge. That means draining it down to about 50% and plugging it in for a recharge. 

It is still a good idea to unplug your device once it’s fully charged to prolong the life of the battery. Their operating sweet-spot is between 40% and 80%. Try to avoid those convenient overnight charges - and overworking your battery while you sleep.
