We can lower the accuracy a little within some sensible boundaries - maybe up to a second, which would halven the battery drain, but there’s not much space after that.The Gear S3 Classic is fully equipped to track your active life with a handful of sensors onboard and preloaded sport modes. So with Samsung, it’s a tradeoff between battery efficiency and accuracy, and it doesn’t really seem to be moving away Is it correct that also the deep sleep percentage is lower for you with the new update? That’s the 10% battery drain you were seeing. We actually used the 2-second accuracy for a while, and that was battery efficient, but the data were distorted towards higher deep sleep. ![]() The internal sensor memory has only space for 300 values, which means that with using sensor batching exclusively, we can only get 2-second accuracy (mainly because we can only wake up the CPU and process the sensor data only every 10 minutes - that’s a hard restriction on the platform). Well, guess what - it’s really not enough on any Samsung watch. We had no way to find the size beforehand for each watch model, so we wrote it in a way that the app may combine sensor batching and keeping the CPU awake if the sensor memory size is not enough for sleep tracking purposes. We then had to rewrite the app so it used sensor batching (a technique which allows the watch CPU to sleep while the sensor gathers data into it’s own internal memory and then passes it as a batch to the CPU every few seconds).Įfficiency of sensor batching heavily depends on the size of the sensor’s internal memory. Its software is more finely tuned to track your workouts. Last year, the app has been suspended from the Galaxy store for battery inefficiency, because we were keeping the watch awake all night to be able to poll the sensor every 100 ms (which is ideal). The Gear S3 Classic may be able to do fitness tracking, but the Polar M600 is one of the best around for sporty types. Android Oreo and Nougat: App power monitor, Background restrictions. We need sub-second accuracy on the sleep tracking data, which at this moment means getting data from the sensor every 500 ms. Even disabling the system battery restrictions does not save the app from being. Hi we’re slowly learning that on the Galaxy wearable platform it may not be possible to have both accurate data and battery efficiency. ![]()
