I noticed the other day that Carrypad listed the battery discharge rates of the Paceblade P7 UMPC in their review, so I promptly downloaded the same application they used and gave it a whirl on the Samsung Q1. If you’re interested, the software is called Notebook Hardware Control and it’s actually very useful for any notebook computer, not to mention it’s free.
Since battery life seems to be particular concern for the UMPC class of computers (and rightly so), I’ve got a comparison of the battery discharge between the Q1 and the P7 after the jump. Bear in mind that the P7 has a 26 W/hr battery, while the Q1 sports a slightly higher capacity battery of 29 W/hrs.
WiFi off, screen brightness at 50%:
- P7 = 11.3 Watts for a runtime of 2.3 hours
- Q1 = 10.0 Watts for a runtime of 2.9 hours
WiFi off, screen brightness at 100%:
- P7 = 11.9 Watts for a runtime of 2.18 hours
- Q1 = 10.8 Watts for a runtime of 2.68 hours
WiFi off, screen brightness at minimum:
- P7 = 8.1 Watts for a runtime of 3.2 hours
- Q1 = 8.7 Watts for a runtime of 3.3 hours
USB devices disabled (through windows hardware control – disables Bluetooth and wifi) screen min:
- P7 = 7.37 Watts for a runtime of 3.52 hours
- Q1 = 8.3 Watts for a runtime of 3.49 hours
Remember that there could be some variance if you perform the same tests; the battery drain tends to jump around a little bit and I’ve tried to let it "settle" to provide an average scenario. Clearly one aspect that helps the battery life on the Q1 is the extra 3 Watt/hours in the battery;
however, it appears that the Intel Celeron configuration is slightly more efficient than the Via setup from this preliminary analysis.
