The good news is most electronics now run on lithium-ion batteries. Lithium-ion batteries don’t suffer from the memory effect and can be recharged at any time. Apple, whose products run on lithium-ion batteries, does recommend that you let your device’s battery drain from 100% to 0% once a month to help maintain life of the battery.

This is because the cell tower isn’t equipped to serve the influx of people in that one area at a given time.
