Jonathan Geller, reviewing the HTC Thunderbolt for BGR:
How does the Verizon Wireless’ first 4G LTE smartphone do in the real world? Well, not that great to be honest — especially with a 1400 mAh battery. Over 3G, the ThunderBolt can easily power through a normal workday. On 4G, however, I couldn’t get more than around 4.5 hours of usage at best… a figure that is not at all acceptable to me.
What makes matters worse is the fact that 4G can’t be switched on and off by the user. There is no widget to disable LTE and there’s not even a menu setting you can check on and off to enable or disable 4G.
4.5 hours of battery life.
I can now see why Apple has not released an LTE phone yet. Not being able to turn off the battery hogging services is stupid. This is unacceptable usage time for any phone. One thing Apple realized is that people want it as a phone FIRST. If it cannot provide that basic duty, then it is useless.
