3 You Should Drain a Battery Before Charging It
This is another myth that, at one point in time, may have had some basis in truth. But modern-day lithium-ion batteries don’t need to be drained before being recharged. In fact, it’s probably better to charge your phone from whatever point it’s at rather than wait until it’s dead. If you wait until the battery is completely drained, you run the risk of stressing the battery, and going through the battery’s charge cycles quicker. Just charge your phone when it needs to be charged and you should be okay.
