Today I decided to try a little experiment with my G2, and put it back on T-Mobile’s HSPA+ network. For the past week it’s been using the 2G EDGE network in order to ensure a practical battery run time.
It seems that T-Mobile must be tinkering with the network, because today I’ve managed almost 11 hours of normal operation and only consumed 30% of the battery. A week ago it was draining the battery dry in under 5 hours.
I would guess that they’ve backed off on the channel bonded access for the moment. The Speedtest.Net app on my handset currently measures my connection to Comcast’s nearest server as 3100 kbps down and 328 kbps up. That’s not bad, but certainly less than their much trumpeted network upgrade should permit.
Given that they have few devices in the market that can actually take advantage of the faster network performance it makes perfect sense that they’d back off on the network changes in order to ensure that the bulk of their 4G customers have workable battery life, at least until HTC releases the firmware update that provides a more permanent solution.
