    I feel my sp4 m3 is going dead too quickly...I am down to 85% after browsing with IE for 35 min with battery saver on and screen at 50%.

    I wouldn't run it to dead but 15% -20% would be OK. Something else is obviously running in the background. Look at task manager to see what's using processor time.

    That equates to just under 4 hours of run time, which is on the low end. You should get at least 6 hours with an M3, IMO.

    To see what's using up your battery go to: Settings => System => Battery Saver => Battery use

    One thing I noticed is that if I charge up my SP4 at night it doesn't start the next day with as much charge as when I charge it up in the morning. It loses some charge overnight, even if it's plugged in.
