Call Time (7.94)
To test call time we make a phone call to the device using Skype and then record how long it takes for the phone to go from full battery power to zero. Because the Upstage ships with an additional battery "wallet" we ran this test twice for the sake of completeness, once with the wallet and once without. Without the wallet the Upstage lasted 2 hours and 53 minutes, with the wallet it lasted a much more impressive 6 hours and 37 minutes. This is a significant difference in battery performance, with the lower number one of the worst scores we have seen from a phone and the higher one of the best. Becuase the battery wallet is an included accessory we have chosen to give the Upstage the better of the two scores, however users should not that if they do not wish to use the battery wallet battery life will suffer significantly.
Music Playback (18.41)
We test battery performance during music playback by playing a test album back continuously at full volume until the battery dies. When testing with the battery wallet the Sprint Upstage put up an extremely impressive 25 hours and 34 minutes of continous music playback. This blows away any other phone that we have reviewed. At this point we have not yet tested music playback without the wallet, we will update this review shortly when that test is complete.
Web Browsing (7.4)
Updated: We have run our web browsing battery test on the Sprint Upstage. To test battery life while browsing the web we point the phone's browser to a web site that refreshes automatically every 10 seconds. We also ensure that the screen remains on and that the phone's buttons are pressed intermittently. The Sprint Upstage was tested with its extended battery wallet, as this is an included accessory. The Upstage lasted an impressive 6 hours and 10 minutes in our test. We will be running this test without the battery wallet for comparison purposes, check back for updates shortly.
Idle Time (0.0)
In order to ensure that we release reviews in a timely manner we do not test standby time. Neither Sprint nor Samsung publish numbers for standby time, however you should note that we expect standby time to be as disparate as other battery performance depending upon whether you use the wallet or not.
