I know this is not a smart watch but it is related to time and something I found that seems very strange with an Android cell phone. I assume this would also happen with a Smart Watch.
I’m not sure why I decided to investigate this tonight but I have an Samsung cell phone with a removable battery - a Galaxy S5. It is not being used and is not on any cell network. Here is what I did:
- Turned on Airplane mode (it was already on actually since it’s not on a cell network) so there would be no cellular connection - not even for emergency use.
- Turn off Wifi
- Turned off GPS (location completely off)
- Turned off Bluetooth.
All those were actually off anyway but I verified all were OFF.
Checked the time on the phone. 7:30PM correct time…
Removed the back cover and pulled out the battery. I let it sit for 3.5 hours with no battery.
After 3.5 hours I put the battery back in and turned on the phone.
Airplane mode still on
Wifi still off
GPS still off
Bluetooth still off
Time upon boot up was 11:02 PM - the Correct Time!
How could the phone know what time it is when it had no battery for 3 and a half hours and no connection to cellular, the Internet, GPS, Wifi or anything that it could get the time from?
Are our phones / smart watches ever really off? Is there a secret tiny nuclear battery in there? Alien technology? Powered by TIME itself?
I have a couple theories. What are your thoughts?
