Galaxy S6 supports the full range of Verizon wireless spectrum, from 3G CDMA to LTE 4G, including GSM networks for global roaming. Call quality is excellent in my tests, with strong volume and natural colors in the earpiece. Shipping via mic is very clear, too, and the effective noise cancellation dampened moderate street noise. Samsung returned the audio tuning feature, which you can use to adjust the tone to your liking, remember, the same quality and media call quality audio effects. S6 also supports Verizon's HD Voice and video calling features.
Winner of last year's Galaxy Note 4 S5 and top marks for their superb performance of wireless networks. Network performance is strong for S6 Still, despite its new metal build, which usually easier to use wireless transmissions. To test side-by-side with the iPhone 6 to Verizon, the S6 comes out on top of an average of 2.5Mbps down and 1.04Mbps up. That's not exactly great, but in a particularly rough day for the Verizon network, the S6 delivered an average of 5Mbps down compared to the iPhone 6 3Mbps down, which you would probably notice with regular use. Unlike the model of T-Mobile, Verizon does not support the feature S6 Download Booster Samsung, which combines LTE and Wi-Fi for more reliable connectivity.
On a battery rundown test, in which we streamed a video on YouTube over LTE with the screen brightness set to max, the S6 take 7 hours, 13 minutes. That is on par with the results we have seen in T-Mobile model, which lasted 7 hours, 48 minutes, and a lot better than the iPhone 4 to 6 hours, 33 minutes in the same test.
