The first 4G Verizon phone, the HTC Thunderbolt, is having problems lasting through a single day on a single battery charge, it seems.
Though these bandwidth speeds are truly remarkable, especially coming from a mobile smartphone, constant use of the 4G LTE network has resulted in a detrimental impact on battery life for the Thunderbolt. I’ve been using the Thunderbolt as my daily driver for the past few weeks now, and it was truly a rare sight to see the battery make it beyond the 6 hour mark with moderate-heavy use, requiring me to charge the device 2 or even 3 times per day to make it through a full day of use. Now, I must state that I do live in an area that is fully covered by Verizon’s LTE network, and it is a well-known issue that the LTE network does have a negative impact on a device’s battery life, but should we really only expect our devices to only last 6 hours between charges?

Of course, the reviewers didn't have access to the new widget that can turn 4G on and off during the day (much the way you turn wifi on and off as needed to extend battery life).
