Nintendo doesn’t want gamers to compare 3DS battery life to other systems
This information comes from Nintendo’s marketing manager James Honeywell…
“3DS is a unique product, so […] comparisons to other portable devices aren’t always applicable. If you look at other high-resolution portable devices, which is probably a better comparison than other portable gaming systems, three to five hours of intensive use is not an unreasonable battery life.”
Well, at the very least, I’d say it’s difficult not to compare the 3DS’ battery life to previous DS systems. I feel as though the 3DS is taking a huge step back. I wouldn’t be surprised if Nintendo released a 3DS Lite version sometime in the future with improved battery life.
