QUOTE( A Note from Cannonfoddr UPDATED 23/02/2011) said:
Since I made this thread - 'Snailface' has created a small NDS test file called 'DS Battery Life Timer'
which allows you to 'test' without having to hang around waiting (which my original 'tests' needed you to do)

So I'm going to attempt to re-run all MY previous tests with this program to see how they differ ...
& I suggest that anyone who wish to contribute to the results should also use that program instead of my original 'suggestions' for tests

However I WOULD still like you to state IF the Wifi was turned off or on when you test on a DSi/DSi XL
(And don't forget to have the brightness up as High as possible)
Thanks

I've seen quite a few people saying that 'such-&-such card affect my DS battery life', but I've never really seen proof of it (the most recent posts have been in the Supercard forums),
so I thought that perhaps the members of GBATemp could do some actual testing to find out not only how much a particular flashcard affects battery life, but also which card offer the best/worse battery life

My suggestion is that Tempers will do one or two tests & post their results, however to make everything 'fair' - the test should be standardized somehow
So here's what I propose.....

Test Conditions....
  • > DS must be fully charged
    > Highest Brightness level possible
    > Sound on Lowest Level (NOT 'Muted')
    > Wifi to be turned OFF on all tests (if possible), unless you're doing a 'WiFi drain' test
    > Game is started and left 'idling' (i.e. letting it show it's 'DEMO gameplay' intros with NO interaction from the player AT ALL)
Note: Time is Noted/Stopwatch started the moment the DS is switched on & Time is Noted/Stopwatch Stopped when DS switches itself off


Now onto the 'tests'-
Ideally I would like 2 tests done - 1 with a Retail (shop brought) game and 1 with the same game running on a Flashcard
This is so we can compare how much difference in battery usage there is between the two
  • 1a: DS with NO card inserted, WiFi turned OFF (if possible), left on Health screen/Main menu - Idling
    1b: DS with NO card inserted, Wifi turned ON, left on Health screen/Main menu - Idling

    2a: DS with Retail game (+ No WiFi), left 'idling' running the games own 'Game Demo/Intro'
    2b: DS with flashcard playing a ROM (Ideally the same as the Retail if possible) + no WiFi, left 'idling' running the games own 'Game Demo/Intro'

    3a: DS with Retail game (+ WiFi turned ON), left 'idling' running the games own 'Game Demo/Intro'
    3b: DS with flashcard playing a ROM (Ideally the same as the Retail if possible) + WiFi turned ON, left 'idling' running the games own 'Game Demo/Intro'

    4: DS running a Emulator & ROM, left 'idling' running the games own 'Game Demo/Intro'
Please note those with DSLite / DSPhat can't turn off their WiFi - so your tests will always be 3a / 3b
In most cases I guess everyone will be doing either test(s) '2' or '3'.
Test '1a/b' is only really to test to see if your battery is not failing, & Test '4' is only really for a 'stress test' or DSTwo flashcards


Also IF you see that a test has already been done (Look at the 2nd post of this thread for current the results) - you don't have to repeat it

How to post results
Could you please post result(s) in the following form:-
  • DS Type: e.g. DSPhat / DSLite / DSi / DSi XL (only one per set of results please)
    Test No: {type in 1a,1b,2a,2b,3a,3b or 4}
    Flashcard/Game: {type in the EXACT name of the flashcard used e.g Acekard2i}
    Time (in Hours/Mins): ?? hrs ?? mins
Examples:
CODEDS Type: DSi
Test: 2a
Flashcard/Game: RETAIL Sonic Rush
Time: 4hrs 06mins

DS Type: DSi
Test: 2b
Flashcard/Game: DSTwo + Sonic Rush ROM
Time: 3hrs 18mins

Some general Nintendo Info
According to Nintendo specifications, the battery life for each DS system on MAX brightness is.....
  • DSi XL: 4-5hrs
    DSi: 3-4hrs
    DS Lite: 5-8hrs
    DS Phat: 6-10hrs (note: according to specs the 'Phat' doesn't have different brightness levels)
So this should give you a rough idea how long it'll take to complete a test
 
Test Results

3DS Tests (please note I did not do these, not having a 3DS - so EXACT testing conditions are not known unless stated)
R4iDS (original, r4ids.cn): 7hrs10mins - Brightness 1, Power Saving On, Volume 50%, snailface's battery timer
AK2i + snailface's battery timer (3ds version)* :6hr20min Brightness 1, Power Saving ON, Volume 50%, Native Resolution ON (256X192)
DStwo + snailface's battery timer (3ds version)*: 6hr35min Brightness 1, Power Saving ON, Volume 50%, Resolution (320X240)

*3ds version of Snailface battery tester uses a non-PA_RTC version as the 3DS doesn't seem to support the PA_RTC function. This uses the slightly less accurate CPU timer instead.


DSi XL Tests
Retail game + Wifi turned off:5hr 15min

DSi Tests
NO game card + WiFi turned OFF: 3hrs 59mins
NO game card + WiFi turned ON: 3hrs 37mins
Retail game (Sonic Rush) + WiFi turned off: 4hrs 06mins
AK2i + ROM (Sonic Rush) + WiFi turned off: 3hrs 24mins
DSTwo+ROM (Sonic Rush)+ WiFi turned off: 3hrs 18mins
M3i Zero+ROM (Sonic Rush) + Wifi turned off: 3Hrs 08mins
DSTwo + NDS-GBA Emulator running 'Metroid - Zero Mission' + WiFi turned off:3hrs 20mins
R4i Gold + DS Battery Life Timer v2.0: TEST TO DO
M3i Zero + DS Battery Life Timer v2.0: TEST TO DO
AK2i + DS Battery Life Timer v2.0: TEST TO DO
DSTwo + DS Battery Life Timer v2.0: TEST TO DO


DSLite Tests
AK2i + DS Battery Life Timer v2.0: 8hr 16min *see note
DSTwo + DS Battery Life Timer v1.1: 8Hrs 06mins (Tried v2.0 several times - Program 'locks up' at random times)
N5 + DS Battery Life Timer v1.1: 6hrs 48mins
NO game card inserted: 5hrs 10min
Retail game (Sonic Rush): 5hrs 00min
R4i Gold + DS Battery Life Timer v2.0: 4hrs 46mins
R4i Gold + DS Battery Life Timer v1.1: 4hrs 44mins NB: Did this to see if there was any difference between the 2 test programs
Acekard 2.1 +ROM (GTA Chinatown Wars): 4hrs 35mins
M3i Zero + DS battery Life Timer v2.0 (using 'Touchpod'): 4Hrs 06mins
M3i Zero + DS battery Life Timer v2.0 (using 'Sakura'): 4Hrs 06mins
DSTwo + NDS-GBA Emulator running 'Metroid - Zero Mission': 4hrs 00min



*note: Yes that IS 8hr 16mins - I even did the test twice with the same settings (High brightness) as the other tests and that's the shortest time I got (the other was 8hr 22mins BTW). How the hell it's >3hr longer I don't know

DSPhat
DSTwo + NDS-GBA Emulator:~4hrs
DSTwo + ROM:~6hrs
 
Interesting topic

To add more variability into the equation, people have said that 4GB and 8GB cards will consume more power than others like 1GB and 2GB models. I have been meaning to test this myself.

Another variable is the age of the unit (batteries hold less charge as the more they have been charged and/or the heat they have been subjected to) and the temperature affects things too. But all things being equal, we should be able to get somewhere...

I've also heard the bits about MicroSD cards can also affect battery life - howver I believe this is such a small amount it shouldn't really affect the general battery life too much

It is a shame that over 100 people have actually looked @ this & yet you're the only one that actually replied to it - guess it's not such an interested topic than I thought
 
Hmm, interesting. Although age also is a great factor in this. Because my old DSlite literally only had 2 hours with a flashcard.
Although that could also be a result of when I used to use it as an MP3 player and left it in my pocket during the school all the time

Still it's good to know that flashcards don't make a huge impact on the battery.

EDIT: What about the factor of flashed DS's?
 
lol, don't be so upset just because you don't get a hot topic
laugh.gif

i bet some of them are testing battery life themselves to make sure there reliable

nice facts, i have both dsi and dstwo cart, i wonder if different games running on either the gba emu or just ds game being booted affect the battery life as well?
Why not give it a try ?? - I know I said 'if a test been done.... then don't bother repeating it', but I guess that since you've thought of it - then others may also want to know

(Hey we might even find out which GAME cause the biggest battery drain

Why use the brightest setting? If you are checking battery levels for how long it would last if you are in a situation where you can't charge it wouldn't you usually use a low-light setting than highest?

True - you would use the lowest setting for seeing how long you could play between charges - but as the post title say 'How much do flashcards affect battery life' not 'how long does your battery last with a flashcard'

After all - can you guarentee you'll be around your DS in 17 hrs time to see it die (you need to be to see the time it did) ?? - I know I couldn't, but 4-5 hours I knew I could
 
Okay, so I'm doing the test on my DSi XL. I've turned off Wi-Fi, I set it to the highest brightness, put the volume at 1 button press from mute, and I guess I'm going to first test it with GBA. I'll do another test tomorrow.

I'm done my test, but I don't want to post my results until I do 2 more tests.
 
I'm bored, so I'm gonna do a test with my Acekard 2.1, DS Lite, running the game Grand Theft Auto: Chinatown Wars. Test starts once my DS is fully charged

Many thanks lads....just don't forget to to include all info required (Yaymii - what flashcard are you using ?, fudgenut - don't forget to mention whether WiFi is on or off)
 
I'm using a DSTWO, but I know my results will be much different than yours, since mine is a DSi XL. I got 4hours 20 minutes on the GBA (no WiFi) test IIRC. It's over an hour more than your results
tongue.gif
I'll format it correctly when I finish the other test(s).
I'm tested Super Mario 3 on GBA, and I'll be testing NSMB on DS. I'll be doing AK2i tomorrow, and I might also be doing retail. Although for some reason, I want to do a GBA mid-brightness test (but I don't have the time).
Also, fudgenuts64 can't really say if his WiFi is on or off ~ he's on a DS lite.
 
Even on a DSi, the WiFi setting doesn't keep it constantly broadcasting, it just means it's enabled, so I'd imagine there is virtually no difference, unless you include the power spent on the indicator light.

But it's proven that the WiFi setting takes a lot of power when idling at the DSi menu, and that takes away at least 2 minutes even if you just quickly boot a game.

Anyways, I kinda forgot that I was supposed to test my AK2i life today, so I'll have to wait for my DSi XL to charge. Oh well. But I kinda want to do the retail first, so I'll just pop my retail New Super Mario Bros. in so I'll be ready.

EDIT: Ugh, I don't have enough time to do a test today. I'll try to do both tests tomorrow.

Unlikely it's JUST the light - if that's the case why did I 'lose' 22mins ??

I think you're partly right about 'doesn't keep it constantly broadcasting' - but IIRC it DOES broadcast it's SSID (or equivalent) on a regular basis, & THAT takes battery power to supply the 'transmitter'

IIRC it's something similar with Mobile phones - the phones battery life is reduced if you leave your Bluetooth switched on, even if you not using it - it is still broadcasting, hence one 'tip' for longer life is to turn it off when you don't use it
 
Sorry I haven't posted. I never got to the test, but I will have results tomorrow.
