6 Letting It Drain Fully

Once upon a time, one of the most predominant phone battery tips was to let a device drain completely before charging it. But it turns out that that’s actually not a great idea. Completely discharging your battery between charges uses up the device’s finite charge cycles faster.

That can lead to an iPhone’s battery lifespan decreasing more rapidly than it should — something that may be a problem among some users. It’s much better to just juice your iPhone up when you need it and from whatever battery percentage it’s at. Some experts recommend keeping it between 50 and 80 percent charged at all times.
