We've been hearing intermittent reports that T-Mobile may or may not be sending new, better batteries for owners of juice-deprived G1s
in the field, but in the meantime, Seidio
has a solution of its own. This 1400mAh battery is rated a full 400mAh higher than the OEM unit, presumably giving you an extra hour or two of Android-powered bliss between charges -- and even better, it fits in the same space with no replacement cover needed. $42.95 sounds steep, but then again, it's hard to put a price on talk time.
