Amazfit Stratos - Bluetooth Chest HRM and battery

What is your battery usage experience using Bluetooth HRM with Stratos ? Mine is pretty bad so far:
- 2 hour hike with BT HRM on and PPG off used 30% of battery. Previously without BT HRM and with PPG on it only used around 10%.
- 2.5 hour hike with BT HRM and PPG on used 45% battery, then after hiking for total of 3.5 hours I switched off PPG and after 4.5 hours I was left with 10% battery.
- BT HRM is Decathlon Dual HRM Belt.

Seems pretty bad to me, sums to around 6 - 7 hours of battery life with PPG off and BT HRM on.

Your observations match mine, Wahoo Tickr bluetooth heart rate strap with PPG off, battery lasted approx. 7hrs - tested on a 13hr Adirondacks hike last week. Next time I'll just use PPG for such long hikes and deal with the HR spikes in the data afterwards.

On a similar note, what are your observations on the best activity to use for hiking: walk, trail run or climbing? Battery time and GPS/altitude accuracy are my main criteria when I say "best".
