Topic: Battery life of DS vs GBA sp?

[xts3]

I'd like to know how long the battery life is (of someone who actually has completely used the batteries up on a regular basis) of the DS vs the GBA sp?

The battery life on the front-lit GBA SP lasts noticably longer than on the DS.  I can't say about the new back-lit GBA SP.  The battery on the Micro is about the same as on the DS (at least on the brightest setting, which is what I always play at).
