I just used the EeePC straight through for the first time, from a full battery (charged overnight) to a dead battery. Total time was 2h48m. <\/p>\n
During that time, I was using the computer in what I consider a reasonably typical manner: reading news aggregator, chatting on IRC, working on OpenLayers. I ran the OpenLayers tests — which are a 100%-of-CPU chewing machine — two or three times, so there was some significant CPU usage in there, and I was also doing things like playing “Crack Attack”, so this wasn’t a ‘practically idle’ machine by any stretch of the imagination.<\/p>\n
This seems reasonably in line with the advertised 3.5 hour battery life.<\/p>\n
Unfortunately, the ACPI support for the laptop is really poor: the battery life is reported as ’40mAH’ at the moment, which realyl means ‘40%’, and it only moves in intervals of 10%. Quite annoying when trying to do any serious determination of the current rate of usage of the machine.<\/p>\n
I think a big power sink in this case is just the fan: when I started doing the OpenLayers tests, the fan turned on, and it didn’t turn back off. I don’t knwo if this is just poor ventilation in how I use the laptop or what, but I assume that having a motor running will significantly affect battery life. Of course, the fan is presumably neccesary to stop the CPU from melting down, so turning it off isn’t exactly an option \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
