De nouvelles infos claires et precises sur la batterie :
Umezu: We announced the other day that the battery duration for playing Nintendo 3DS games on it is about three to five hours. When I measured it by playing several Nintendo games, with the backlight set to the brightest level and the power save mode turned off, battery duration was about three hours. But if you use the power save mode under the same conditions, it gets about 10-20% longer. And if you set the backlight to the darkest setting, the battery lasts five hours, but the power save mode makes less of a difference then.
Iwata: In other words, the brightness of the backlight has the greatest effect on battery duration.
Umezu: Right. What's more, with the backlight set as high as it will go, battery life changes about 25% according to whether you're playing in 2D or 3D.
Iwata: Yes, 3D is a battle against power use. How about wireless use? Some players may be worried about that.
Umezu: In StreetPass mode, the system isn't always communicating, so there isn't much of a drain on the battery, but games that communicate a lot through local play and online play—with the backlight set to high—have an over 10% effect on the battery.
Ce qu'on peut en deduire :
So, we know how power save works now (it's basically the same as dynamic contrast on LCD TVs) and Streetpass isn't constantly communicating. We can roughly guess the battery life.
3D: 3-5 hours (4.2 hours with WiFi on constantly) (Highest Brightness is 4 hours with power save on)
2D: 8 hours (6.5 hours with WiFi on constantly)
8 heures de durée de vie en mode eco ca me va tres bien.
Par contre je trouve la conclusion de gaf pas en accord avec les chiffres d'iwata rie.
Je tombe sur ces chiffres :
3d on, max brightness : 3h
3d on, max brightness power save on : 3h36
3d on, low brightness : 5h
3d off, max brightness : 3h45
3d off, max brightness, power save on : 4h30
3d off, low brightness : 6h15
