I thought that I charged mine once every three days, but there's a similar topic that got me wondering and paying attention, and it turns out that my phone can last for a whopping eight days...if I don't use it for anything. Maybe once every three days was back when the life connected to my phone (social, business) was more active. I can believe having to charge a phone more than once a day, too! New models have so many features and a screen full of colors and movements, that's got to sap a lot of energy.
