Review: LG Optimus G for AT&T
The G's display is fantastic. It measures 4.7 inches across the diagonal and packs an impressive 1280 x 768 pixels. You can't see the individual pixels, even when you hold the phone up close to your eyes. The display is an LCD panel with LG's in-plane switching technology. It's simply one of the best displays I've seen on an LG device. It is crisp, sharp, bright, and colorful. It’s perfectly usable outside, and I had no trouble using the camera to take pictures of my kids playing soccer on a bright and sunny afternoon.
The G did an admirable job at finding and connecting to AT&T's HSPA+ and LTE 4G networks. The G displayed three or four bars of coverage in most places I took it. More to the point, though, it never disconnected from the network nor lost signal entirely. The G always connected calls on the first dial, never dropped a call, and always delivered speedy mobile data performance. AT&T's HSPA+ network, which offers abundant coverage, is fast enough for most everyday needs. AT&T's LTE network, which is growing slowly, is just ridiculously quick. I routinely hit peak download speeds in excess of 40 Mbps with the G on AT&T's LTE network.
The G is a good voice device thanks to mostly clear calls and a loud earpiece speaker. Calls I made with the AT&T G had just a wee bit more static and background noise than the Sprint G did, but it wasn't too bad. As with the Sprint version, the AT&T version's earpiece packs a painful punch when set up all the way. I was easily able to hear callers even when standing next to cheering moms and dads at a soccer game. In quieter environs, you can turn the volume down to 50% for a really nice experience. The speakerphone experience on the AT&T G is OK, but not as good as the Sprint version. There's more noise introduced in calls, and the speaker isn't as loud. It's still acceptable to use in a low-key home or office, but not so much in a noisy coffee shop. Ringers and alerts are acceptably loud, but could be better. You probably won't miss most calls, and the vibrate alert is good.
Both the Sprint and AT&T versions of the device gave me a hard time, battery-wise. As with the Sprint variant, the AT&T G never lasted more than 24 hours in total from a single charge. It would make it from 7AM to 11PM, but just barely. Use it heavily, and you can be scrambling for a charger at dinner time. The battery did not appear to drain any faster when used on AT&T's LTE network. I used it on LTE about half the time I tested it ,and LTE had no noticeable impact on battery life. Even so, you'll need to pay attention to the battery with this device and have back-up chargers or other power supply available at all times.
