BatteryEater results on the Q1P
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!

your result states that q1p has a led backlight!!!
yup.
Its got a LED backlight. 280nits gives it away.
Until now I thought that the Q1P had the normal screen.

Cool! thanks :) That’s what I suspected: the Pentium processor is by far much more efficient. Lucky you ;)
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 …
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.
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?
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.
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.
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..
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.
It would also need HlD touch drivers …
With current drivers/bios you can’t get any Tablet PC specific features.

No. Not perfect Brian.
Mouse pointer and docking port is missing!!
If they came out with a version based on the new Celeron 1.6Ghz ULV with mouse pointer and PCI-express card capable docking station I would sell out to get one!!
Steve.
This is very good news for me. I am considering getting a UMPC, replacing my Acer Tablet and am blogging about my search. (umpcsearch.blogspot.com) One of my biggest concerns was battery life. Glad that these new UMPC’s battery lives are improving.
i thought it had a mouse pointer. if not that is a big deficiency in the samsung. perhaps we’ll have to wait for that kidc model to make an appearance.
Confirmed High voltage inverter! NO LED SCREEN!!! I just bought my Q1p last week also. Model : NP-Q1-V002/SEA
Just took my Q1p apart and there is a high voltage inverter with the classic pink and white high voltage wires leading into the screen. This means there is a lamp inside the screen and NO LEDs.
I am NOT getting 2:38 on battery eater but only 1:56. IMO the tests are flawed. I dont believe any Q1ps have the LED screen. What I think happened is that he ran his Q1p with the autosceen shut off feature on. Hense the 2:38 he got.
Grimster, thanks for cracking open your unit and checking; I haven’t done that yet. I didn’t sit by the Q1P when I ran the test, so I can’t confirm that the screen shut off during the test or not; all I can do is run it again, which I’ll do today or tomorrow.
I can tell that during real time usage, I used the Q1P last night for about 45 minutes with WiFi on. I checked the battery level at that time and it was around 73%. I then put the unit in sleep mode for dinner; roughly another hour. After I woke it up, I used it for another 1.5 hours, some of which that time was used to also run an external optical drive. I was doing a long installation (Office 2007) and saw the battery level warning icon in my tray so at that time I plugged it in. Roughly got 2.25 hours with an hour of sleep mode in the middle, which is more than I used to get with the Q1. I’ll re-run the tests of course….
I should also mention that I had e-mail conversation with Steve at Carrypad yesterday and shared some Notebook Hardware Control data. In a relatively idle state, the Q1P was drawing around 7.5 to 8.5 watts with WiFi on. Turning the WiFi off yielded a drain in the 6.75 to 7.5 Watts. Bear in mind that all Q1 models have a 29 W/hr battery and that on my prior Q1 the drain was in the 8.7 to 10.8 watt range. I can’t see the Pentium making that difference but again, I’m willing to do more testing when time permits.
Is there a way to get the brighter screen to the q1. The q1 isnt bright enough on the low settings. And to watch a movies the brightness level has to all the way up. And that kills the battery.
i think the celeron models have a defective standard battery. the q1p probably has batterys that are doing what they should have been doing in the first place. 2-3 hrs real world usage.
my q1′s standard battery is only giving me an 1hr of usage. i’m trying to return it to samsung.
That sounds like a battery problem for sure. I routinely got 2+ hours on the Q1 standard battery which at this point is 8 months old.
My standard Q1 battery still gives me about 2 hours of use, give-or-take ten minutes, even though NHC is reporting a “wear rate” of 30%. (I left it running in the case once, and it hasn’t been the same since.) Before the wipeout I used to routinely get 2.5 hours on the 3-cell.
Getting only an hour out of it sounds like a fried battery to me, too.

Stewe: you should run battery calibration tool in bios to get it back..
Ok here are some facts about my Q1P model number NP-Q1-V002/SEA.
Standard 3-cell battery.
Wear level: 7%
Full capacity: 26640 mWh
Battery Manager Rate: Normal
Screen at LOWEST brightness (1/8)
CPU Speed Dynamic Switching and running at ~600 MHz
NHC -8,92W (Wireless On) and -7,737 (Wireless Off)
Battery Manager Rate: Normal
Screen at HIGHEST brightness (8/8)
CPU Speed Dynamic Switching and running at ~600 MHz
NHC -10,034W (Wireless On) and -9,613 (Wireless Off)
All wattage numbers are reported when the computer has
idled a bit to settle on 1-3% CPU load. The charge rate
seems to fluctuate somewhat even at idle. At times it
jumps up and down 1 watt.
Now lets see the same numbers with More CPU power!
Battery Manager Rate: Max Performance
Screen at LOWEST brightness (1/8)
CPU Speed Max Performance and running at ~600 MHz
NHC -10,29W (Wireless On) and -8,136 (Wireless Off)
Battery Manager Rate: Max Performance
Screen at HIGHEST brightness (8/8)
CPU Speed Max Performance and running at ~1 GHz
NHC -11,333W (Wireless On) and -10,49 (Wireless Off)
So my Q1P seems to draw about 2 watts more than Kevins and some others. I guess the LED panel is something they have sneaked into the production at a later stage and some of us just got unlucky and got the old one! :(
Ah the woes of copy paste, the 3rd reporting with Max performance and lowest brightness should read “CPU Speed Max Performance and running at ~1 GHz” naturally. :)
I think battery eater would empty my battery in 100 minutes or so… no luck here with that LED screen! :(
