I haven't owned the computer long enough to give you a really good answer, but I do know that Dell sells two batteries for this computer and the 58 watt-hour one is the bigger one. The 5th gen i7 is the most power efficient of the 5 generations of i7s but how long the computer will run depends on variables like: how brightly do you keep your screen? Do you have Wifi and Bluetooth enabled? Even when you're not using them? Are you powering an external CD or DVD drive? I suspect it will run at least 2 hours and you might be able to stretch that out to more hours if you're stingy with your power usage, but I just can't give you the specifics yet.
Sorry, there was a problem. Please try again later.I've been using mine for 4 weeks. The battery life will, of course vary depending on what you're doing, how bright you make the screen, if you're powering peripherals like external hard drives, what the temperature is, what power plan you've selected (ie what you've throttled the CPU down to), etc. - but I've had no problem passing 4 hours of use on battery power.
Sorry, there was a problem. Please try again later.Depends on how you use the computer, but I'm getting around 6hr with it, currently.
