[QUOTE="pigoo3, post: 1742880, member: 56379"] It's really not about "extending battery life" or "shortening battery life". It more about how long before the battery needs replacing. The batteries Apple has been using in Apple portable computers since about 2009/2010 are rated for 1000 cycles (1 cycle = 1 complete battery discharge & recharge). If someone uses 1 cycle/day...that means this person will be able to go almost 3 years before 1000 cycles are consumed (3 years = 1095 cycles). If someone only uses 1-2 battery cycles/month (like I do)...then the battery will last much longer. But it's not exactly this simple (batteries tend to lose some of thier life over time due to natural degradation). But for the most part...the faster the battery cycles are used up...the sooner someone will need a battery repalcement. - Nick p.s. And even at 1000 battery cycles. The battery is still supposed to reatain 80% of the runtime compared to new. In other words...if a MacBook Pro battery was rated for about 8 hours of average runtime on a single charge when new...then at 1000 battery cycles...it should still get about 6.4 hours (80%) of average runtime. But. After 1000 battery cycles the battery may lose battery runtime at an accelerated & unpredictable rate (the battery runtime loss after 1000 cycles may not be linear). [/QUOTE]
