Seriously, though, there is a strategy to answering questions on the exam. This is critical if you are trying to figure out how to pass the SPHR exam. This is strategic in nature, meaning that itâs about how HR ties in, and drives, business activities and measures.
After the laptop has gone through a full single charge and the power plug is unplugged the average life of a laptop battery can be anywhere between one and six hours.
The real killers of lithium batteries(the kind in your phone), is heat & frequent full discharge/recharge cycles. They have a design life of 3 ~ 5 years, & will last much longer if not subjected to frequent discharge cycles below 40% of capacity. Apple recommends you let your battery fully discharge/recharge once a month...every couple of months will be just fine. So, to maximize your battery life, charge your phone as often as possible & avoid high heat.
