COROS is proud to be known as the leader in GPS watch battery performance. Our products are able to achieve an impressive battery life in a compact size due to our top-notch, power efficient technology. What’s most important, unlike some other brands in the industry, is that we can assure your battery will last as long or even longer than what we presume. Most watches in the industry using the term “up to” however many hours, typically won’t last the user that long and if anything could be less. For instance, while our COROS APEX 42mm has 24 hours in full GPS mode, a lot of our users have exceeded this performance by having some remaining juice after a 24-hour race.
In the real world, battery performance is affected for a variety of reasons. Things like the strength of your GPS signal or setting up your watch, can impact the amount of battery the watch is using. Our advertised battery life takes consideration of normal user preference, but we feel it is important to let everyone know the battery consumption for each component of the watch. Here are some interesting stats for you.
We have broken down each part of your watch using the numbers below to give you an idea of the power consumption. (Assuming turning on GPS and running with it is 100% battery consumption). Keep in mind this is just an estimate because each watch model can be a little different from each other due to different hardware designs.
|Normal GPS activity with HR||100%|
|Indoor Modes w/o GPS||20%|
|POD or other sensors connection||70%|
To use this data, simply add them all together. For example, running with GPS is 100%, but running with GPS with the backlight always-on would use 235% (100%+135%= 235%), which is more than two times the power consumption. If you add a sensor such as COROS POD to your run, the power consumption will become even higher to 305%. With 3 times the power consumption, you would only get 20 hours of GPS workout time with your COROS VERTIX (advertised as 60 hours). Thanks to the innovative Night Mode in COROS VERTIX and COROS APEX Pro, you will only increase 15% of your battery consumption if you want it to be always-on throughout your night race.
Another thing to note is the data above is a measurement for the same length of time. Having multiple notifications on the watch can take up quite a bit more energy but can be minimized by reducing the number of vibrating alerts you get throughout your run/workout. Meanwhile, each alert brings up backlight for a few seconds, which is another huge factor to your battery life.
Navigation takes about 10% additional battery from your watch. When you turn on navigation but only scroll to the navigation page when needed, this will most likely put your battery performance back to the normal range.
The bottom line is frequent alert with vibration and backlight, POD or another sensor connection, oximeter measuring is a big part of your unexpected battery consumption. If you are in a situation where battery performance becomes critical, try to turn them off, and you will be amazed when you find our products’ performance exceeds what we promised.
