Conclusion: The Butterfly S has taken some great features from the HTC One and mixed them up with an amazing long-lasting battery. We love its display, we love its front stereo speakers, we love its longevity. Then again, it’s not a perfect device. The large battery has taken its toll and the phone itself feels bigger than we’d like, even a bit unwieldy, and the camera shoots underwhelming pictures.
Pros: Huge long-lasting 3200mAh battery, Great vivid 5” 1080p display, Impressive front stereo speakers
Cons: Large and thick, unwieldy, Camera is below average for its class
Summary: If a faster processor and bigger battery trump a sexy metal design, then choose the HTC Butterfly S, otherwise skip it for the HTC One.
Pros: The HTC Butterfly S boasts a 3,200mAh battery and a half day of uptime, a powerful processor, and a brilliant screen. Its camera performs well in low light, and a microSD card slot offers the option of adding more storage.
Cons: The glossy plastic materials of the HTC Butterfly S lead to lots of fingerprint smudges, and the phone isn't water-resistant like its predecessor.
