UPDATE: The Bold 9700 battery just died. The BlackBerry Cool official time is 19:22, exactly 29 hours. This is 29 hours while using the device heavily. Let’s see an iPhone do that!
UPDATE: 16:19 and 26 hours into the test, with 10% battery left. Part 2 of the test has sort of changed. It started off as a test of the music playback under more strenuous network conditions and has turned into a test of how long the battery will last under power user conditions. I’ve been playing music, tweeting, taking pics, using Google Maps, running several other apps simultaneously, making and taking calls and constantly pulling data from both Maps and Twitter. There was a break when I went to sleep but I left all the connections and apps running so it was still very much active.
UPDATE: 14:16, 24 hours into the test, and the battery is at 25%. Something I’ve noticed is that making calls depletes the battery much faster than anything else. I knew this intuitively but the test really made it obvious. Streaming music doesn’t seem to have much impact on battery life at all.
UPDATE: 10:40 went through the night and we’ve been back on WiFi, radio for a couple hours. At 30% and around 20 hours we’re definitely going a full day no problem.
UPDATE: It’s 02:29, 12 hours into the test. The batter reads 40% and I have been using a very decent amount of apps and data. Holding the BlackBerry Button, it shows the following apps: Messages, UberTwitter, Home Screen, BlackBerry Messenger, Media, Radio Companion, Setup Wizard (I switch devices a lot), Visual Voice Mail, Google Maps, Browser, Gmail and Phone. I’m going to give the updates a rest until around 8 AM.
