Since 3DS came out last month,good reputation about 3DS is full of the world, because it is really great with its highlight features, except one thing-- the battery life.Since i got my own 3DS last week , i did some tests on it , just like other guys said, everything is great except the battery life, it is even worse than you can imagine,the battary sucks
Before i bought it , i already did some research that the battery life won't be that good , and i alrady got ready to get used to it , but now , i finally released that it really has a bad battery. Nintendo officialy reported that it can support 3-5 hours 3DS games,5-8 for regular DS games, after i played it for one week , the truth is 3 hours at most.
3DS will arrive in Europe and US at the end of this month, but we can make sure that the battery life won't be better than japan version, disappointed thing!
But there is also solution about this problem too, it is reported that famous game console accessaries company Nyko will solve this problem and players just need to buy a battery pack to double the battery life, about 20USD,already cost us 250USd , and will take us more money in games, accessaries and flashcards....
