1. How long does your version of the 3DS battery last and do you have a Regular or XL? 2. Do you take it with you whenever you're going somewhere? 3. Do you have Streetpass turned on as well when you're going out? 4. How long have you used the 3DS in one session consecutively? 5. How long do you think the battery will last you if you use it how you have been? This is an overall amount of several years time. 6. Do you use the 3D function a lot or rarely? Thank you in advance. I just need to compare some things to how I use it.
