battery

[griffo70]

my battery says its calculating for quite a while now ? *** , also i made another post about batterys, but dont no what to do , is it alright to charge it all the time i use it or should i let it drop, plug it back in to full charge , unplug it , let it drop and start again

if i seem abit obssessed i just dont wanna have to buy a new battery for ages,
also how many hours would i expect to get using photoshop quite heavely and listenin to music? i get 3 just wanna check thats ok?
cheers and sorry

hmmm

i charge my macbook twice a day and leave it chargin on the second charge for a few hours, at night, just because i dont want it to go below 50% is that gonna fully break it very quickly?
