The latest tests done by Laptop Mag compares the battery life of some popular Android handsets in the United States, and Verizon Wireless’s latest Droid offerings come out on top with the Motorola Droid X taking top honors followed closely by the Motorola Droid 2.
With a modified battery life testing custom-created app, Laptop Mag doesn’t take into account phone calls, SMS messaging, or other features, but rather the app’s main focus was screen usage while surfing the web. They had prepped the phone with these conditions to create as even a playing field as possible:
1. First, we download My Settings and Advanced Task Killer, two free apps that are useful regardless.
2. Then, we open My Settings, and do the following:
3. Turn screen brightness to 40%, and turn off auto brightness.
4. Turn off Wi-Fi, Bluetooth, GPS location, cell location, and auto sync.
5. Deactivate screen timeout; that is, make sure the screen stays on indefinitely.
6. In the Web browser, we turn off Flash support and plug-ins.
7. We placed the phone in an area that was receiving at least 4 bars of service.
As a result of the test, the top three devices were the Motorola Droid X, the Dell Streak, and the Droid 2, all faring above average. Sprint’s offerings were just below average, with the EVO 4G and the Epic 4G offering comparable performance and leading other Samsung Galaxy S devices, like the Vibrant and the Captivate. The regular AMOLED display of the Droid Incredible placed last.
With the Super AMOLED screens of the Galaxy S series and the AMOLED of the Incredible finishing towards the bottom of the heap, it seems that there isn’t really a battery life advantage for AMOLED/OLED display technologies. However, the test only looked at part of the picture: “OLED technology uses the most power when displaying white, which is why Samsung chose a black background for the app menus on its Galaxy S phones. Since our battery test surfs web pages, most of which have a white background, both the Galaxy devices and the Incredible were at a disadvantage. It really comes down to what you view most often on your phone.” Looks like if you’re a heavy web surfer, LCD screens can offer you better battery performance, and of course, text on web pages will look a little crisper than on an AMOLED or Super AMOLED screen.
