No, it has to be plugged in to charge. But I've found if you close it while playing a DS game (only DS games), when you close it, it doesn't lose any power, but it certainly doesn't charge itself while closed.
charge it
No, the DSi uses a different charge to the DS lite.
A DS Lite Charger can be used to charge a Nintendo DS Lite. It's best to always fully charge the battery once it's empty. This will give a longer live to your battery.
No, the DSi charger is different than the DS lite charger
If you plug in your ds lite to charge and you see an orange light that means it's charging. If you're seeing an orange light without plugging your ds lite in to charge then I'm not sure what it means.
Charge up your Nintendo
yes
You can charge it whilst it's on or off.
on a ds at the back it does NT ssay ds lite and on a ds lite it says ds lite
Yes you can. You can also connect DS lite to DS and DS Lite to DSi.
Yes you can. It doesn't matter where you charge it.
To be honest there is no phone charger
