Battery charging best practice

Friday, 4 May, 2012

A good pick-up from the Guardian on battery charging with this summary salutory advice:

What does all this mean in practical terms? Unless you have specific instructions from the manufacturer to the contrary, you probably can leave a device plugged in if it is truly off. Otherwise, you probably should not leave it plugged in for much more than an hour after the "fully charged" indicator comes on. This gives you the greatest chance of giving your battery the longest life possible. This may not matter for a device that you are going to replace every year or two anyway - such as a cell phone - but for devices that you intend to keep for several years, such as a laptop or tablet, you may want to be more conservative in your recharging practices.
