The battery life here is pretty excellent, just like the HTC One X on AT&T and the HTC One S on T-Mobile, you’ve got the Qualcomm Snapdragon S4 backing your whole system up with its ability to stay strong without draining the life out of your day via the battery. Count on this device to last you what it’s lasted us, that being 10+ hours a pop with heavy use, no problem. If you’re the type of person who only uses a device lightly during the day, don’t worry about charging it up except at night when you head to bed – always a good practice anyway.
