This stat is when I'm surfing and youtubing all the time. No timeout at all.
Your results are typical for most phones when you are surfing, Youtubing and have 4G on. If you are that heavy a user then you would do well with either the Razr HD Maxx or Note 2.
My last phone was a Samsung galaxy nexus and b4 that the Samsung droid charge and both battery life r terrible so the note will prolly be the same. Must be the antenna on the Samsung's. Razr maxx is great on battery life.
