Updated: 30 June 2025
Smartwatch battery life greatly depends on your usage. Heavy use of features like GPS, continuous heart-rate monitoring, and an always-on display can significantly reduce battery life. However, as technology is constantly advancing, newer models tend to offer better performance and battery optimisation. When you buy a watch, here are some key tips worth noting. Keep these factors in mind:
- Display Type: OLED/AMOLED displays can be more power-hungry than LCDs or transflective displays. Look for options with smaller screens or those with excellent power optimisation.
- Always-On Display (AOD): This convenient feature keeps the display on all the time, but it will take a toll on battery life. Consider turning it off or scheduling it for specific times.
- Processor: Newer, more efficient processors consume less power. Opt for smartwatches with power-efficient chipsets.
- Features that affect battery life:
- Built-in GPS.
- Continuous health monitoring (heart rate, SpO2).
- Cellular connectivity.
- Battery Size: A larger battery generally indicates a longer potential life, but it also adds bulk to the smartwatch.
While choosing for longer battery life, also consider which features are essential to you and which you’re willing to compromise on to save power (cellular connectivity, always-on display, constant health monitors). Note that hybrid and outdoor-centric smartwatches usually prioritise long battery life over other features. Smartwatches with customisable battery-saving modes let you disable unnecessary features when you need to squeeze extra juice.
These affordable watches are compatible with Android and iOS smartphones. They have the longest battery backup for prices under 3K. Prices indicated are as seen at the time of updating this page.
Note: The battery life given for each smartwatch on this list is based on user reviews on Amazon.
