all those expensive $80 (FAT ONES) mugen batteries are a waste of money imho. the 1600 mah are an ever worse ripoff.
you're paying a premium for the privilege of being spared the horror and anguish of schlepping an extra battery around.
THANKFULLY, our batteries are pretty small and thin, so it's really not such a terrible thing.
anyone use the "EXTENDED" batteries before? how much extra life do you get? NOT VERY MUCH.
if i use my phone "normally" with a 1500 mah battery, it lasts the whole day, or around 15 hours for me.
if i use my phone "normally" with a 1600 mah battery, how much longer battery life will i get?
mah = milliamp/hour = milliamp per hour
1500 ma/15 h = 1600 ma/ X h
plug and chug, cross multiply, whatever, SOLVE FOR X hours.....15.999 hours.
WOW! 1600 mah batteries give you just ONE (1) extra hour of battery life.
the cheapest you can find a 1600 mah battery on ebay is $37.99. you can buy THREE (3) 1500mah batteries for $11.99 and free shipping.
i think it's quite simple to see that the "extended batteries" are just not that great an option.
i quite enjoy math. nergasm ;P
