SOT is a useless stat. Battery drain is determined by the type of apps you use and the way they consume resources. Playing a GPU intensive game for 30mins will probably have a much greater effect on the battery than someone watching YouTube for 3hrs.
The responses you're getting also are about uptime instead of SOT. Getting a real apples to apples comparison will be very difficult without comparing with someone with the same hardware/software/apps/usage pattern.
