Yesterday, I got a request from Jose over at palmInsider; Jose asked if I could run a battery test on Samantha so he could compare the results on his Celeron-based Samsung Q1. I did one better because I ran BatteryEater on Sammy way back in August and the minimum battery time was 1:44:45 or roughly 105 minutes.

The above graph is from running Battery Eater on Samantha last night. I tried to replicate the test as best as possible with the same settings and remember, Samantha has a 50% larger hard drive running at the same speed and the same 1 GB of RAM that Sammy has, but she runs the Intel Pentium M at 1.0 GHz. The Pentium supports speed-stepping, while the Celeron does not. The results speak for themselves: Samantha will get a minimum runtime of 2:38:24 or roughly 158 minutes on the same battery. One other note: the Q1P offers a 40% brighter screen over the Q1: 280 nits vs. 200. I find that I can set the brightness to the lowest level and it still seems brighter than on the prior model. Hope this helps, Jose!

  1. your result states that q1p has a led backlight!!!

  2. yup.
    Its got a LED backlight. 280nits gives it away.
    Until now I thought that the Q1P had the normal screen.

  3. Cool! thanks :) That’s what I suspected: the Pentium processor is by far much more efficient. Lucky you ;)

  4. Pentium prosessor is NOT much more efficient.
    Battery eater tests on Tabletkiosk i7210 show same results as celeron version i7209.
    It’s the LED backlight …

  5. Even with the speed-stepping, the processor can’t be adding that much more power savings. I’m sure the Pentium doesn’t hurt any, but the backlight has to be contributing the majority of the savings here. What’s interesting is that I didn’t see any mention of LED backlighting in the Q1P specs; there is a note on the Samsung site about the 280 nits, but they didn’t specify how that brightness increase was created. Guess we now know! I just took several pics of the Q1 and Q1P at the same brightness settings and will post them up later this afternoon.

  6. I got the Q1P and at night or dark room would have it on the lowest brightness and is still very bright, never thought that they would have used the LED light display. Is there a way to check some where on the Q1P to see if indeed it is using the LED lighting?

  7. Kevin forgot one question, on the 3 cell battery how many hours does it say on your battery icon when you charge it up and start to use it with the battery? Also which battery program do you use the one that samsung has or the NHC program. I have the bluetooth on and brightness set to about 40% and it shows 2:45, what does your say. I do have the 6 cell battery and that one gives me 6 to 7 hrs way cool. Since am on the road like 90% of the time its good to have as much battery. I do have the iGo to charge the battery when in the car also.

  8. I’ll be very curious to see what the OQO 02 can pull on this test.

    Not that I can afford one, mind you, but for purchase dreaming.

  9. HG, just open your device and if you can’t see any inverter connected to screen, it uses leds ;)
    Inverter in q1 is about 1cm x 10cm pcb with 2 silicon cables connected to screen..

  10. it seems to be that led lighting is great for battery life. all we need is either intel support for wddm drivers or samsung to switch to the 945 chipset and we have the absolutely perfect umpc for vista.
