How to Extend Laptop Battery Life

Keep your Laptop Battery away from heat: I know it’s a “Laptop” with emphasis on the “Lap”. That doesn’t mean it should go directly on your lap, a pillow, or anything else that can tighten up the vents of your laptop. For longer laptop battery life, use your laptop on a more solid surface like a table.

Use the Laptop Often: Don’t charge your laptop, and leave it dormant for a long period of time, try to make use of a charged laptop, at least once in about two weeks.

Completely Discharge your Battery Once a Month: You can do this by removing the A.C Power outlet (charger) and letting the battery “die” completely once every month. In case of a Li-ion Battery, never let it discharge.

Stop Overcharging your Battery: When not in use, remove the Laptop charger if the battery is full, don’t keep charging it. It won’t go beyond 100%.

Turn off Your Laptop: If you are not going to use it for more than 5 hours, shut it down. This would help reduce the wear and tear on your battery, thereby increasing laptop battery life.

Clean Battery Contact with Alcohol: Periodically clean the laptop’s metal contacts, by rubbing with alcohol on a damp cloth. Please Note; Only clean the battery contacts, when battery is fully discharged.

How to Save Laptop Battery Power During Usage

Defrag your Hard Drive: The more fragmented the hard drive is the more work it needs to do, and the more battery power it would consume during usage.

Ditch the Standby option; Use Hibernate Instead: Leaving your Laptop in Standby mode will continue to drain your battery. If you plan on using it soon I advice you hibernate. Your work won’t be tampered with, and you’ll save battery power.

Use Power Saver Power Plan: Most Laptops offer 3 power plans; the Balanced, Power Saver or High Performance. Common sense will tell you that the Power Saver plan saves power. You can easily change power plan options, by clicking the battery meter icon.

Upgrade you RAM: I bet you didn’t know this one. If your laptop’s RAM is high, processes will be carried out faster, thereby saving power. Please don’t do this yourself, meet an expert.

Remove any CD, DVD or USB from your Drive, if not in use.
Close all Unnecessary Applications
Reduce or Mute Volume level, if you don’t plan to use it.
Reduce Screen Brightness
Disable Wi-Fi and Bluetooth

This is true especially when you charge your laptop and leave it unused for one month and above. I left mine for work, when I came back it was telling me to replace the battery
