Leaving Your Laptop Always Plugged In Will Kill Its Battery Faster

Leaving your laptop always plugged in will kill its battery life faster, according to a recent report from Wired. In fact, you shouldn't even let it charge to 100%.

Cadex Electronics CEO Isidor Buchmann tells the site that ideally users would charge their laptops to 80% and then drain them to 40%, prolonging their battery life by up to 4x.

The reason is that each cell in a lithium-polymer battery is charged to a voltage level. The higher the charge percentage, the higher the voltage level. The more voltage a cell has to store, the more stress it’s put under. That stress leads to fewer discharge cycles. For example, Battery University states that a battery charged to 100 percent will have only 300-500 discharge cycles, while a battery charged to 70 percent will get 1,200-2,000 discharge cycles.

This is simple in theory but much harder in practice. The report suggests timing how long it takes your device to charge from 40% to 80% and then setting a timer when you first plug your laptop in to charge.

If you can remember to follow Buchmann's advice, a four times increase in battery life is a significant improvement.

what a funny and misleading information. if the battery life time is 400 to 500 charging cycle, and let the battery last for 10hours, that mean the battery will work 4000 to 5000 hours, if discharged fully and then charged fully. with the information in this study, if we charge upto 70% and discharge upto 40% as suggested, the battery will have 1200 to 2000 cycles. so for 3hours of usages times, then the battery will have 3600 to 6000 working hours. what is the difference. very funny study

Laptop is one of our best companies in our daily life. We use laptops for different purposes. One of its best facilities is using it without power. But the backup depends totally on the battery and the settings. We often fall in problem while using it without power. The low backup time makes trouble. Maximum time the battery backup time average is highest 3 hours. What’s the solution? You have to choose the laptop with the longest battery backup. Now, I am presenting the longest battery life laptops of 2013. http://hightechbd.com/top-8-laptops-with-the-longest-battery-life-in-2013

Call your service provider, they will unlock it for you for free if you aren't in the contract, you don't need to jailbreak or use some other third party service for remote unlock, if you are in contract then find a friend whose contract is complete and switch your IMEI of your iphone with a different phone's IMEI on your account then update your iphone IMEI to your friend's account and call the customer service to get it unlock since the contract is up for your friends phone and they will unlock it for you, once the unlock is dont put the SIM card back into your iphone,. your will be unlocked for free from your own service provider, if you have any questions then let me know, thanks..

Remove battery when it charged 100% to avoid damage from excess heat and you can plug it back when you are going out with laptop. Problem solved :)
