Gaming ds lite energy consumption

[azakhan]

Does anybody know how many watts the ds lite uses in its various brightness modes? I read that a wii uses 16 watts and the ps3 uses 150 watts when in use.

I can not help you with the brightness modes or even a DS lite but I did do measurements of the power for an original DS in various conditions a couple of years back

You could probably infer something from the capacities and how long it took to discharge (timed discharge tests are a bit more common)
Anyway my tests

Most of the good stuff

Test results are in, if it does not say current is measured in milliamps (mA):

Apparatus was an ammeter (basic cheap multimeter with no auto ranging- we were in the 1-200 mA range for all tests and the meter can be used in the micro amp range anyhow) in series with the positive terminal of the two parallel batteries (batteries on their last legs really which I consider quite useful for this as it allows me to infer some things).

Test results
Menu- 100-110mA to 130 (pictochat), spikes depending on what I am doing although that is probably obvious.
Official carts:
Warioware 120mA- fluctuates 8mA either way.
Nintendogs- 137 mA
Advance Wars dual strike- 124mA
It should be noted on early boot/menu is lower (Nintendogs is 3d remember)- all values are for normal play scenarios unless otherwise noted.

Sleep mode with warioware 1.8-2.1mA
Sleep mode with EZ5 1.90 OB9 and EZ5 with SDHC (see below)- 31.8mA flipping between 31.3mA and 31.8mA.
For giggles adding my EZ4 with warioware (official) pumps current draw up to 148mA or so (varies quite a bit). I am guessing SRAM draw (similar for 3 in 1 if not worse due to motor).

EZ5 test = Tetris DS- CPU level 4. Were I to be going full on science mode then I would find a ROM of the games I was using up there but I will leave that for now. It should not affect it but in the spirit of a proper test it is my hacked version that plays the Korobeiniki all the time in original modes.
Original DS- light on, sound up, no headphones, no wifi, flashme, nothing in GBA slot. EZ5plus with 1gig Sandisk.

EZ5 2.0 RC4- soft reset and everything. GBAlink, med rumble.
150mA - fluctuates 1.5 either way.
EZ5 2.0 RC4- nothing, gbalink, weak rumble.
154mA - fluctuates 12 mA or more on occasion.

1.90 OB9- no cheats, low or med rumble (not that it matters)
160mA fluctuating 8 either side, high side more than low.
Edit/update: Thought I should make it a "proper test" so Advance wars Dual strike (European version like my original) also clocks in the 150mA range (again varies) on 1.90 OB9.

For giggles with 8gig class 2 Sandisk with 1.90 OB9
148mA fluctuating 6 either side.

The max rating on the back of the system is 2.3 watts, but as FAST's post shows its even lower in practice. Take the (mAmps*5.2) / 1000 to get the watts in his post. For example, 150 mAmps is .78 watts.

Wow thanks guys really useful
