Battery Performance and Portability Index
Gaming notebooks seem to be doing better these days in terms of battery life. The era of the 40-minute power outage appears to be over, with most notebooks managing to hit at least the 1-hour mark. Samsung, who make their own batteries, have fitted the 700G7A with an 8-cell unit rated at 15.1V with an 89Wh capacity. In testing, the 700G7A performed better than the X770, but not as well as the M17X R3, lasting just over 1 ½ hours.
|Specifications / Notebook||Samsung Series 7 700G7A||Alienware M17X R3||Toshiba Qosmio X770|
|Battery||15.1V / 89Wh||11.1V / 90Wh||14.4V / 47Wh|
|Dimensions||407.5 x 267 x 39.8 / 49.9mm||405 x 321 x 51 / 53mm||414 x 274 x 28 / 61mm|

Power consumption for the 700G7A is quite high, even in terms of gaming notebooks, with the 700G7A performing much worse than both of its competitors.
Our Portability Index measures how portable a machine is based on a simple formula of battery uptime divided by the product of the unit's weight and volume (the lower the score, the less portable the unit is). Gaming notebooks, with their big size, heavy hardware and low battery life generally fare badly in this test, and they’re not really designed with portability in mind anyway. Having said that, the 700G7A did score better than its peers, beating every 17-inch notebook except for HP’s Pavilion dv7 (which isn’t a gaming notebook).
