Google Voice just got a small update in the Android Market. The changelog is short and sweet, telling us the update will improve battery usage, and keep the screen on while playing back voicemails. Anytime we see the words improvement and battery in the same sentence we pay attention. And since Google Voice is probably the app we depend on most around here, we're glad to see it. Keeping the screen on during voicemail playback is a handy fix as well, especially if you use a PIN, password, or pattern on your lock screen.
We'll have to see about these battery improvements, and there's only one way to tell. Grab the update from the Android Market on your handset.
