Mystery of the HTC 10 Lifestyle is solved, and yes, it is a phone
As it turns out, the HTC 10 Lifestyle is indeed a new phone. It is the name being given to the version of HTC's new flagship model that will be offered in some parts of the world. The HTC 10 Lifestyle has the Snapdragon 652 chipset under the hood as opposed to the Snapdragon 820 SoC that powers the HTC 10 in the U.S.
In addition, the Lifestyle variant contains 3GB of RAM instead of the 4GB employed on the HTC 10. And instead of offering buyers the option of purchasing the phone with 32GB or 64GB of native storage (which are both available with the HTC 10), the Lifestyle variant is being sold only with 32GB of ROM inside. There is a 2TB capacity microSD slot, however, for those seeking more storage. And lastly, while the HTC 10 features Cat.9 LTE speed (450 Mbps down, 50 Mbps up), the HTC 10 Lifestyle supports Cat.6 LTE speed (300Mbps down, 50 Mbps up).
So there it is, the mystery of the HTC 10 Lifestyle has been solved. And for those of you in the states, you don't have to give it another thought.
