Knowing your heart rate at all times seemed to be the big take-home message from the unveiling of the Samsung Galaxy S5 and accompanying wearables late on Monday.
At a high-profile press conference at the Centre Convencions Internacional Barcelona (CCIB), J.K. Shin, head of Samsung's mobile division, showed off his company's new flagship smartphone, the first in the world to come equipped with a heart rate monitor.
On his wrist he also sported the Galaxy Gear Fit, a wristband that among other things measures the wearer's heart rate. Samsung also revealed two updated versions of its smartwatch, the Galaxy Gear 2 and Galaxy Gear 2 Neo, which come with longer battery life, a 4 GB memory for storing music, a larger collection of apps and yes, you guessed it, a heart-rate monitor.
The reason for this is because health and fitness forms one of five focus areas for the fifth iteration of Samsung's Galaxy S smartphone.
The other four are style, video and image capturing, speed, and durability.
When it comes to style, the Galaxy range has taken care of that with a perforated rear cover for the S5 and changeable straps and interfaces for its smartwatches. For budding photographers, the new 16-megapixel camera on the S5 comes with all the bells and whistles that users have come to expect over the years. Durability is handled by a water-and-dust resistant case and an ultra power-saving mode that tweaks the settings to extend the last 10% of battery life for an extra 24 hours.
Speed is where things get really interesting though.
The Galaxy S5 has a Cat 4 LTE modem that currently connects to every LTE band going. It sports an 802.11ac WiFi modem, which supports multiple-input, multiple output (MIMO) for faster connection speeds. It also comes with what Samsung calls 'Download Booster', a feature that combines the WiFi and LTE modem to significantly increase download speeds to up to 400 Mbps.
"The Galaxy S series has been one of the key drivers of smartphone growth," said Shin, who thanked Samsung's 200 million Galaxy S customers.
The Samsung Galaxy S5, Galaxy Gear 2 smartwatches and Galaxy Gear Fit wristband will go on sale in 150 countries from 11 April. Price details have yet to be announced.
U.K. operator EE, as well as phone retailers Phones 4u and Carphone Warehouse, have all announced they will stock the Galaxy S5.
