Title says it all. My H2o seems to go on and on without the necessity of a charge. For whatever reason my Voyage is using more battery. Maybe I have the light on more than on the Kobo. I keep the wireless off unless I need to download from Amazon.
As you know, before the smart phones it was suggested to let batteries run down to 20% or so because they have memory. Referring to laptops .... Smart phones have different batteries, and it doesn't matter at what point you put them on the charger.
So what about ereaders ? If my Voyage is at half mast, should I go ahead and charge it, or wait until it goes to 1/4 ? Or does it not matter at all ?
