Save Battery Life

Some precautions and application of some settings you will maximize battery life (that is to say the service life of the battery until it is necessary to recharge) and the lifetime useful to the battery of your laptop. Also make sure to use your Apple computer in his comfort zone in terms of temperature. So, do not leave it in place overheated in summer or in a cold environment in winter. (See "Temperature ranges for your laptop.) For best performance, use your Apple notebook between 50 ° and 95 ° F
Temperature ranges of your laptop. Apple laptops work best between 10 ° and 35 ° C. Their storage temperature should be between -25 ° and 45 ° C. This corresponds to ranges of 50 ° to 95 ° F and -13 ° to 113 ° F. Ideally, your Mac must be maintained at a temperature as close as possible to room temperature (22 ° C or 72 ° F). Software Update Your new laptop
Remember to fully charge the battery in your laptop when you use it for the first time, then perform a software update to be sure you have the latest software version. Apple issues regular updates to optimize battery performance. Standard Maintenance
For proper maintenance of a lithium-ion, it is important not to let the electrons in it moving occasionally. Apple does not recommend leaving a laptop plugged permanently. An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs to recharge after coming to office. By cons, if you're using a desktop computer at work and you use your mobile occasionally, Apple recommends charging and discharging its battery at least once a month. Long Term Storage
If you do not use your laptop for more than six months, Apple recommends storing the battery charged at 50%. If you store a battery when it is unloaded, it could move to a state of deep discharge which might make it unable to maintain any load. Conversely, if you store a fully charged battery for a prolonged period, it could sustain a loss of capacity, which will have a negative effect on its useful life. Be sure to store your laptop and its battery at the correct temperature. (See "Temperature ranges for your laptop.) Energy Savings Optimum setting of the battery
