The battery knows when to charge and when not to charge. Well if you open up the laptop and remove the battery , which you could do. The laptop would go down to reduced performance , this is totally normal. Even dell does this

i thought all manufacturers can bypass the battery already? no?

This means it's ok for me to keep the Magsafe Power Adaptor plug in to the AC outlet and with switch turn "on"?

yes. how else would u do it?

TQ. For your clarification.

meh, this is one of my biggest concern too. the only difference, my unibody mbp's battery is not removable so i dont really have any choice.

my mbp is less likely to be on the move, so most of the time it will be on magsafe adaptor. and according to apple's guide, battery calibration should be done weekly, and that's what i've been doing. From the battery capacity logging data in Coconut Battery, it appears that my maximum capacity has deteriorate to 97% after 8 cycles of charging.

my question is, is this descending trend a norm? i dont want to be anal about the 2~3% of the whole thing, but i certainly do not wish to see a 10 or 20% drop after 50 charge cycles.

the first 1-5% drop is normal. my battery is 1.75 years old and it's at 85% health, 323 cycles. i guess this is pretty low compared to others but it's good enough for me. still can last through a whole lecture. 1 hr lab with vmware + windows 7 running matlab also can tahan. i calibrate once every two weeks

juz use ur battery however it's convenient for you within ur warranty period. i think after 1 year still >90% is good enough dy

and i wonder why mine is only 20months but dropped till 77% with only 50 cycles?

20 months with only 50 cycles... of course lar... electron tarak bagi jalan, battery pun karat... i did 40 cycles in just 3 months, and for that also I considered plugging it too much to power too often already, not good in the long run...

yea... 50 cycles is too little for 20 months. dun be scared to use ur battery

You got a point here. Nightly, I surf 3 - 4 hours and thus 1 charge cycle can hardly last me 2 nits surfing. Was trying to avoid hassle of charging the battery. By the time I finished surfing, it will be close to 1am. Don't wanna wait for battery to be fully charged b4 switching off power as not sure whether can let the MBP charge throught the whole nite until next morning. That'll be some 5 hours of charging. Wonder it's ok to let it charge over night.

wow..20 mths at 50 cycle?
i'm already at 42 cycles, close to 5 months old but i use around 3 months only

mine 160 cycles..LOL

anybody use this anti-theft program before? can share your experience?

mine is at 80cycles, 15months old.

Mine's at 55 cycles, 13 months and on going.

Look like my capacity drop a bit from previous. Don't know what happen every time discharge my battery until finish then recharge back, the cycle charge count is increased by 2 means previous 4 cycle and yesterday discharge and after full charge check cycle is 6. Still not understand what happen.

looks interesting, n free thx for sharing. quite hard to find reviews so im not sure good or not

just bought MBP 13" ..
was in dilemma either to buy 13" or 15" last time ..
at last decide to go just with 13" .. and im glad cause 13" is just nice in my lap. i think 15" would took more space ..

hope this is a good purchase ..
