HTC Butterfly 2 review: Caterpillar

GSMArena team, 7 October 2014.

Display

The HTC Butterfly 2 opts for the same 1080 x 1920px 5" panel as the One (M8) and One (E8) and rocks an impressive pixel density of 441ppi.

The more detailed tests we performed on the HTC Butterfly 2 show the 5" panel as a solid performer. Contrast was impressive at 50% and 100% brightness and is around the same as that of the HTC One (M8) and (E8) and the new Apple iPhone 6. Brightness was also impressive rounding up a very solid display performance.

Outdoor legibility is good although not the best. The screen is reflective but not overly so and the good brightness makes sure it remains visible. Viewing angles are excellent as well.

Battery life test

The Butterfly S set the bar pretty high with a 3,200mAh battery and we were somewhat disappointed to see the Butterfly 2 opt for a smaller 2,700mAh unit. During our tests, the newcomer managed around the same times in the individual tests but failed to match the standby of the Butterfly S. Compared to last year's model's overall rating of 81 hours, the HTC Butterfly 2 comes rather short with its 66 hour score. It's not a bad result on its own, but we are used to seeing scores improving year on year, rather than degrading.

The Butterfly 2 did well in each of the tests. The calling and web browsing endurance was stellar, while the 10 and a half hours of video playback was solid if not quite up there with the best.

Our proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating. Our battery testing procedure is described in detail in case you want to learn more about it.

Connectivity

The HTC Butterfly 2 packs a solid set of connectivity features, perfectly matching the One (M8). You still get quad-band GSM, 3G, and LTE support.

The local wireless connectivity has Wi-Fi a/b/g/n/ac and DLNA support (both client and server, for images, videos and music) and stereo Bluetooth 4.0 with the higher-quality aptX codec. There's also an IR port that allows control over various devices like TVs and, with a bit of software help, digital cameras, AC units and more.

HTC has conveniently designed a special options screen, when you connect the Butterfly 2 to a PC. The long list of options includes Portable Wi-Fi hotspot, settings, USB and Bluetooth tethering (the phone becomes a modem).

NFC connectivity with Android Beam is available too. There's a microSD card slot too supporting up to 128GB of storage.

USB On The Go and TV Out functionality are available. That gives the HTC Butterfly 2 an IR port, USB OTG, TV Out and Wi-Fi ac over the HTC One (E8).
