Batteries in laptops make it easy to work everywhere without the need of a power outlet, but with time the length to use a battery shortens. After a while, your laptop discharges faster than in the beginning: this loss in capacity is irreversible.
However, the life of your battery depends on how much power your laptop consumes. High-performance CPU use like rendering and graphics editing depletes your battery faster than just text editing. Every time a battery discharges, it loses a small bit of its capacity.

Battery life

You can extend the life of your battery by following the next tips:

  • Turn off your wireless and/or Bluetooth (on-off button) if you don’t use it.
  • Reduce the brightness of the screen.
  • Disconnect your external drive if you don’t use it.
  • Remove the battery if you continuously leave your laptop plugged in a power outlet.
  • If you are not using your laptop, disconnect the power adapter to prevent continuously charging and discharging.

If you don’t use the laptop for a longer period, follow the next tips:

  • Remove the battery if you store the laptop for more than two weeks.
  • Store the battery with 30% to 50% charge.
  • Do not expose your laptop to high temperatures for extended periods (like inside a hot car)

Periodically (every three months) calibrate your battery. How to do this depends on your laptop. These are the necessary steps:

  1. In your Power Options set everything Always On. So your laptop always stays on, your screensaver stays off, etc. (maximum power consumption)
  2. Fully charge your battery (100%)
  3. Disconnect your power adapter and keep your laptop on, until the battery is empty and your computer automatically shuts down
  4. Connect your power adapter, but do not start your laptop. Keep the adapter connected until the battery has completely charged: in general a little light indicates if your laptop is charging.
  5. When done, choose a power option which saves energy (like a screensaver on, etc.)
