Huh. Google And Blog is reporting that T-Mobile has been planning to deliver a Christmas Present to all T-Mobile G1 users in the form of a new longer-lasting battery. The current battery is an anemic 1150mAh and any G1 user will tell you that it drains FAST. Anything over 1150 mAh would be lovely. If T-Mobile were giving out exchanges to improve battery life, they would definitely solve the complaints of many users.
As great as this sounds there is still no official word from T-Mobile, so we'll take a wait and see approach on the rumor. We're unsure of how T-Mobile can manage to pull this off, so we're going to do some more investigation and report back. Keep your eyes peeled!
