The first charge battery test continues…
About 4:50pm at 5% battery life the Gear S warned that battery power is critically low and said to charge it now. I didn’t.
A call came in at 2% that I didn’t recognize (area code 657), so I let it go to the mail box, but forget that I haven’t set that up yet. Oh well. (Note to self: Set up mail box!)
Shortly thereafter… 1%... Then a warning your battery power is critically low, charge now to keep using it came on. About a minute later it went 0% DOA at 5:45pm and shut down. So the first charge on the phone battery only went from 2:00am 11-10-14 to 5:45pm 11-11-14 with what is typical normal use for me, with a little extra fiddling around with the phone screens to climb the learning curve thrown in. That’s just short of 40 hours and basically covered 1 ½ to 2 days.
Next I snapped the quick charge battery pack backup on and a lightning bolt battery picture showed up with a 1% below it; indicating the charging process had begun. I turned the phone back on, but a message came up stating that continuing use while charging may prevent the battery from charging properly. So I turned the phone back off and let it charge while off.
The % indicator slowly started to increase over the next hour up to 50%, and then it didn’t light up anymore when I shook it, so I assumed it was fully charged. Turning the phone back on indicated that it had a 50% charge. I unsnapped the backup unit and was back in business by 7:00pm.
I’m thinking a 50% charge is all a fully charged battery attached to a fully drained battery can charge the drained battery, because at that point each battery is at 50% and power no longer transfers between the two. I could be wrong about that, but it seems to make sense. If so, the backup may be good for a second 25% charge after the phone runs out of juice again. That too is pure speculation on my part.
Here’s a quick summary at this point:
1)The Gear S will warn you at 15% battery charge that it is getting low.
2)It will warn you again at 5% battery charge that it is critically low and you need to charge it now.
3)At 1% it gives you a final warning that the battery is critically low and you must charge it now to continue using it, then shuts down shortly thereafter.
4)The phone battery itself lasted ~40 hours in "my" real word use test (of course, your mileage may vary).
5)The quick charge battery backup takes ~1 hour to charge the phone battery and should remain off during that time.
6)The backup battery provides a 50% charge transfer to the phone battery.
That’s where this “real world” battery test stands at this time. I’ll let the phone battery go through the entire cycle once again to 0% and reattach the quick charge battery backup without having recharged it to see what happens. I’m guessing the 50% charge will get me to tomorrow afternoon of day three. We will see.
