Hacking Battery Life With GBA Expansion?

[LeonardoGolden]

I've noticed that my battery life lasts noticeably less when I have my GBA expansion inserted, whether I'm using it or not.

Exactly how long does the battery last with the GBA expansion in?

I'd like to know if there are exact measurements somewhere as well.



Someone told me in a thread here once that (on the lowest light setting):

with gba expansion pack = 9-10 hours
without gba expansion pack = 13-14 hours

Hmm with my gba expansion pack on the setting just after the highest light my DS runs for around 11-12 hours. This is when I'm playing a few homebrew games and DS games.

I did my own little test, with my M3 Real. I used the Zelda Phantom Hourglass Main Menu cinematic on loop, at full brightness.

Without GBA Expansion: 3:45 (225 min)
With GBA Expansion: 2:55 (175 min)

The maths says that battery life is shortened by 22%, or that power consumption has increased by 28% by simply having the GBA Expansion plugged in.

I'm convinced that my Battery is dying though, since I'm pretty sure it's been through at least 300 charge cycles in the last year. It's been left plugged in while running countless times, too.
