Battery Eater 2
The devices fall into three groups which are clearly outlined in both diagrams. The first group includes the ASUS A3500L and the Toshiba Satellite M35X-S111 which perform quite impressively for this class of notebooks. The explanation is simple – an Intel platform plus a normal battery plus a not-very-high maximum brightness of the screen. Summing up both diagrams, we have one leader, which is the Satellite M35X-S111. So if long battery life is your priority, you don’t actually have much choice here.
The second group consists of the LG LS50e and the HP Compaq nx6110 – their have similar results, normal for notebooks of such configuration. The third group embraces all the CPU/chipset alternatives, among which the Samsung P28 alone could yield more or less satisfactory results. The Acer Aspire 3003NLC and the Fujitsu Siemens Amilo Pro 2030 with their low-capacity batteries cannot be recommended at all to people who need to work on the run. I would even regard these two notebooks as having an integrated UPS rather than an accumulator battery.
