You can't accuse Samsung of neglecting older watches, as it's emerged the four-year-old Gear S2 smartwatch is in line for a new firmware update.

It's been a couple of years since the model last received any attention, though, as spotted by Sammobile, the watch's latest software rollout will see battery life and security improvements.

Upgrade: Best Samsung watch in 2020

It's not entirely clear how far the new update will stretch, or whether it's limited to devices in certain territories, but users will be able to download it from the Galaxy Wearable app. From the app, simply head to 'Watch Software' before tapping 'Download and install'.

We're yet to see the 6.79MB file pop up in our app at the time of writing, but there are a couple of reports to suggest that the update will also bring the interface of the Galaxy Watch Active 2, the company's latest smartwatch.

Of course, it's a bit of a surprise move by Samsung, particularly when it's on the cusp of potentially launching another flagship of its smartwatch, the rumored Galaxy Watch 2.

However, you can't knock the continued support for older models. And considering the Gear S2 launched in October 2015, anybody who hasn't retired the watch to their bedside table's draw will no doubt be grateful for the added battery boost.
