LG Optimus G (Sprint) review

LG's most powerful yet phone arrives on Sprint

TODO alt text

We thought a quad-core processor and 4G LTE support would spell trouble for the LG Optimus G's battery. Since the battery is non-removable, we were worried, but ended up pleasantly surprised with the phone's 2100mAh cell's performance.

We did give it a run with the TechRadar battery test. After 90 minutes of playing a video file with full brightness, WiFi, 3G and GPS enabled, it still had an impressive 73 percent of its battery remaining. That's not bad at all, considering the size of the Optimus G's display and the drain of its quad-core processor.

It didn't score as high as the Samsung Galaxy SIII though, a phone that also has a quad-core and the same 2100mAh battery. The Galaxy still has 82 percent at the end of our testing.

Testing the phone around town, we found that a day of heavy usage would generally have battery life in the twenties by nighttime. This is after a day of browsing the web, checking Facebook, making calls and watching videos.

Overall, the Optimus G's better life is respectable. It's definitely a charge every night kind of device, but it's reliable enough to get you through the day with average use.

3G

The LG Optimus might be 4G capable, but for the average Sprint customer in the U.S., it'll be a 3G device. While Sprint is expanding its limited 4G LTE network, it's just not available in most markets, including our own San Francisco Bay area.

Although it can feel like dial-up after using 4G, Sprint's 3G is reliable and blankets San Francisco quite well. We only experienced connectivity issues in extreme locations, like when driving across the Bay Bridge. It was easily good enough for web browsing and streaming radio services like Spotify. Obviously, more data intensive services like Netflix and downloads from Google Play suffered the most.

Data speeds were generally within the 800-550KBps range, which is pretty average for 3G service. The speeds themselves were not impressive, but we were generally able to maintain reliable, four-bar connection, even in crowd urban areas.
