Review: LG G4 for AT&T

Form Performance Basics Extras Wrap-Up Comments  


The G4 has one of the best screens available in the market today. It measures 5.5 inches across the diagonal and has quad HD (2560 x 1440 pixel) resolution. LG's IPS LCD panels are generally excellent and the G4's is absolutely top notch. It's crisp, bright, and colorful. Viewing angles are excellent, and there's no color change or brightness drop when tilted. Outdoor viewability is quite good, as well. If the G4 has one killer feature, this is it.


The LG G4 was a strong performer on AT&T's network. I tested the phone in New Jersey and New York City and came away impressed. It almost always had access to LTE and connected calls on the first dial every time. The phone dropped to an HSPA connection several times, but I didn't notice any impact on the ability to make calls or surf the web. Data speeds were fastest under LTE coverage, but the G4 was quick even in HSPA coverage areas. Email loaded in a flash, and Instagram photos uploaded in a blink. The G4 did well in known weak spots.


Call quality on AT&T's network was superb (just like on Verizon's). I was pleased with both clarity and volume through the earpiece. The G4 did an excellent job. Voices sounded warm and present, as if the person was in the same room with you. Those I spoke to through the G4 said I sounded very good. The speakerphone offers plenty of volume, but was prone to distortion with the volume set high. Ringers and alerts produce plenty of noise and should get your attention most of the time. The vibrate alert is of average strength. It got my attention most of the time, but not always.


The G4 has a 3,000 mAh battery, which is one of the largest available in this class of device. I found it provided a full day of battery life, but it didn't quite have as much juice left at the end of the day as the Verizon variant did. It consistently delivered 16.5 hours of uptime, with just a small amount of power to spare at bedtime. I always leave the WiFi, Bluetooth, and GPS radios active, and I had the phone connected to a smartwatch most of the time. That extra battery LG is offering with the G4? It could come in handy with the AT&T version, especially if you're a heavy user.

LG gave the G4 a modest battery saver tool. You can set it to come on automatically when the phone reaches 15%, or toggle it on/off manually. It doesn't do much to conserve energy, however, and is limited to squashing background processes and notifications. It can extend your battery long enough for you to get safely home at the end of the night, or to find a charger, but it's not going to magically produce an extra day of standby time.

The G4 supports Quick Charge technology and will score a massive boost in energy after just 15 minutes plugged into the right type of charger.
