With the HTC One M9 now available in Europe, HTC has taken the wraps off a refreshed version of its predecessor for European markets. The new HTC One M8s brings a familiar curved metal design to the table, along with trademark HTC features like the Duo camera and BoomSound front speakers, only now powered by a 64-bit Qualcomm Snapdragon 615 processor. That's the same mid-level ARM64 chip powering the company's main mid-ranger, the Desire 820.

Same all-metal design on the outside; new CPU, bigger battery and refreshed camera on the inside.

Other hardware changes from the M8 include a jump up to a 2,840mAh battery, same as the M9, and a 13-megapixel main camera, backed up by the depth-sensing Duo camera. Out of the box it runs Android 5.0 Lollipop alongside HTC's Sense 6 UI — the same software experience you'll find on a fully-updated vanilla M8, but not yet the latest Sense 7 software from the M9.

Elsewhere, the One M8s closely matches the hardware of its forerunner, and it comes in the same three main color options: silver, gold and gunmetal grey. As you can see, it looks pretty much identical to the regular Snapdragon 801-powered M8. From a user experience perspective, though, the main difference should be slightly improved battery life thanks to a more efficient chip and larger cell.

The HTC One M8s will sell for £379.99 in the UK. We'll bring you more on pricing and availability as we get it.
