How long is battery life?

Im thinking of getting either a DS or psp and battery life is a big issue for me. The psp is only 5 hours of battery life at the most and i was wanting to know how long you can play the DS before battery dies.

read the instructions book...

It was something like:

With the lowest brightness it will last 15-18 hours depends on the game playing

With the highest brightness it will last 6-8 hours depends on the game playing

If your saying 5 hours for the PSP it's just proves my right choise(getting ds instead of psp)

With backlight on it's about 7-10 hours depending on game and DS, I got the old one.
Local Wireless connections will put it to maybe around 6-8 hours and I get around 3-4 hours most with Online Wi-Fi but again, I got the old DS.

DS Lite is like 16 hours I think.

Here is a link to the PDF version of the DS Lite's manual... http://www.nintendo.com/consumer/downloads/DSLite_english.pdf

It says that on the lowest brightness, the system "will last from 15-19 hours depending on the type of game activity." If it's on the brightest setting then you will get 5-8 hours. Enjoy!
