Testers are saying the battery life is great but relative to what? I'm sure it will be alot better than other phones, but it doesn't matter if a Smartphone has a 3000 mAh battery, you should ALWAYS have it charging when its not in use and possible. You should have a Desk dock for work, a car charger for all vehicles you uses daily, a charging dock for your nightstand/bedroom, a charger in your home office and a couple charges in other places you use alot like a spare in the glove compartment when visiting friend's house for a while. This isn't a moto RAZR, you must have it charging all the time and you will never have a problem with battery life.
