[Samsung Gear S] eclipse05x:
Hi guys!

I would like to start a small project. The whole point is to find out in which circumstances battery is running down faster/slower. It's more less about consumption and I hope we all will benefit from that simply by knowing what to avoid and if some features of Gear S are really draining battery or if it's just a myth.

I'm really looking forward to update this project in time.

Because of the nature of this project. I would love to get some help. Even if one person wants to participate I'll be thrilled.

Each test takes quite a lot of time so we can get more results if we will work together. I choose to run tests for 10 hours as it will give us more accurate results than anything shorter. 10 hours seems to be right as smartwatch still can be used during the day and whats more important, battery can be run down before recharging and testing.

Watch always on (6th watchface) Wifi/Network/BT(unpaired) off - 10h: 22%

Watch always on (6th watchface) Wifi/Network/ off - 10h: 23%

Watch always on (1st watchface) Wifi/Network/ off - 10h: 23%

Watch always on (Watcher) Wifi/Network/ off - 10h: 25%

Watch off (6th watchface) Wifi/Network/BT off -10h: 9% Comment: I was expecting less usage. BT in GearS was still ON as it can't be turned off (but not connected)

Connected via Bluetooth (Watch/Motion/WiFi off): 10h 11% Comment: Apparently when it's paired with phone (sync) does not make much of the different

Connected via GSM without data (Watch/Motion/WiFi off): 10h 18%

Connected via GSM with data (Watch/Motion/WiFi off): 10h 20%

Connected via UMTS with data (Watch/Motion/WiFi off) - 10h: 20%

Talk time on UMTS with data (Watch ON, Motion off, WiFi off) - 2h21m Screen was lighted up few times just to have a look what's going on

[By saying BT off means that do not keep it connected to your phone]

[While connected to Bluetooth or via cellular network make sure to deactivate all notifications in GearManager App - test will be useless if any notification will be delivered to the smartwatch]

To do a test just after a day of use charge your Gear S fully. After reaching 100% still wait approx 20-30min, choose what test you want to participate, disconnect from a charging cradle, switch the screen off and set an alarm to check it back after 10h

Observations:

Having a "Clock Always On" is not that bad idea. During 10h test it consumed 13% more than without it (6th watchface). So we can assume that during all day (approx 16h) we're loosing only 19-20% of juice. Is it bad? I don't think so... especially because you don't need to light up the whole screen just to check what the time is - which will consume some energy too... In the end of the day it still depends of that how often you need to check the time. If you are doing that very often, than "Clock Always On" is... lets say... more energy efficient solution (and looks much better than dark screen).

The only problem with "Clock Always On" is that, almost every touch, raindrop, wet sleeve triggers screen to turn on and it's very inconvenient for the battery life and it can messing around in the interface - it happened to me when i was walking in the rain.

In my opinion touchscreen should be inactive during that mode or even to give such an option to tick in the settings menu.
