Supposedly, lithium ion batteries like to be totally drained before being charged and then charged to max before being unplugged. I personally find this regime difficult to attain with phones because I'd rather not have the phone die while I'm far from a charger, so I often start charging when it is at 20% or so. And when I have to go to work, I unplug the phone, even if it isn't at 100% charge. I think most people do similarly, but the battery would really prefer you use it all the way up and charge to max. I think this is what the GP means by "carefully charging."
- dsego 8y agoIsn't that regime for old NiMH batteries that had the "memory" effect? I thought for lion it's the opposite, never fully charge and never fully drain.
- stefanfisk 8y agoYep, fully draining just wears the battery down faster.
- Yaggo 8y agoNot true. Actually, the less capacity is utilized (of theoretical maximum), the longer will be lifetime of li-ion batteries. For example, if kept between 20%...80%, they may last for 10x more cycles. That's why electric cars' batteries does not need to be replaced every couple of years.
