Check this for my Samsung 850 Pro.

9 Power_On_Hours 0x0032 084 084 000 Old_age Always - 78917

I ran a extended test, and thought it didnt log, so then ran another. However I realised what was wrong, check this.

Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed without error 00% 13380 -
# 2 Extended offline Completed without error 00% 13374 -
# 3 Short offline Completed without error 00% 58475 -
# 4 Short offline Completed without error 00% 56423 -
# 5 Short offline Completed without error 00% 56212 -

Note that the higher in the list, the more recent the test, see how the more recent tests are lower power on hours than the earlier tests.

Take the current power on hours 78917 minus 65535 = 13381. I assume one hour since test. Wonder if this is standard across all devices.
