Runlio T115 Smartwatch 1.47" Heart Rate SpO2 5ATM 25 Sport Modes Black

What the Runlio T115 is and who it suits

The Runlio T115 is a lightweight activity tracker with a 1.47 inch LCD touchscreen that shows 240 by 240 pixels. It pairs with Android 4.4 plus and iOS 9.0 plus phones over Bluetooth to deliver call, message and app alerts. Buyers who want built-in GPS, onboard music storage or contactless payments will not find those features here.

Capacity and headroom: health tracking and battery

Continuous heart-rate and SpO2 monitoring run 24 hours a day, while automatic sleep analysis breaks rest into deep, light and wake segments. The lithium-ion cell lasts five to seven days under active use and stretches to fifteen days on standby. Users who need multi-week endurance without charging or clinical-grade ECG readings should look elsewhere.

The specification that decides fit: 5ATM water

A 5ATM rating means the band withstands swimming, showering and rain without damage. Twenty-five sport modes cover walking, running, cycling and pool sessions, recording steps, distance and calories. Anyone who requires dive-depth logging or high-pressure water-sport certification will need a device rated beyond 5ATM.
