Real battery life

How much battery does your FR955 loses per hour during an outside activity?

FR955 Solar With All systems or Auto-Select I am just over 6% (previous watch) and now with the new one (4 times charged total) in GPS only it looses about 5-6% per hour running with BT HRM,  light off, FW 14.20.

Bike - GPS only, 6% per hour with BT HRM, cadence sensor and varia radar connected and with 80-90% solar intensity...and about 10 cars detected/alerts total. No map or navigation. That is way off from the official claims - that would be 16-17 hours total in GPS only (OK, with 3 sensors) with full battery. GPS with OHR is claimed up to 42 hours for ordinary 955...What I get is about 2.5 times less than claimed...

Without activity I could get 2 (or just over) weeks...if no drains, but I wasn't inactive that long since the new watch arrived. I have a feeling that a previous 9 months old watch had a bit better battery life.

Is my way off or you get the similar results?

    that's fantastic. you are seeing numbers almost as good as my All Satellites one. i may have to revisit multi band. maybe Garmin tweaked the algorithm in the last few firmwares? (i only tried it a couple of times last summer but settled into All Satellites since it works well for my run locations)

    My battery life has been much better with 15.12.  24 hours off the charger with a 40 minute run this morning and I am at 93%.  My long term average was 8.9 days per charge, but reporting 11.98 days/charge right now.  About 5 hours of SatIQ running each week.
