You’ve got a new Notebook – one thing that is common to all these is the battery and what we ALL want is better Battery life.

Operating Systems are becoming more and more graphic intensive, whilst applications do everything they can to hog system resources. The average battery life per continuous use still stands at a maximum of three to four hours.

Rather than carrying an extra battery pack, there are several ways to increase the life of your battery. Here’s how…

1. Defragment your Hard Drive

Defragmenting your hard drive is the process of ordering your information in a way that allows your PC to access the data more efficiently and effectively. The quicker your hard drive is able to access it’s stored data, the less of an impact it will have on your battery. Mac’s move your files around when you initially save the file, meaning there is no need to defragment the drive.

2. Manage when tasks are run

Whether it is Defragmenting your Hard Drive, running a virus scan, updating your virus definitions or updating your version of Microsoft Windows. These are all tasks that can wait for when the device is plugged into a power source.

3. Unplug external devices

If it does not need to be plugged in, unplug it. Hard Drives, USB Memory Sticks, PCI cards all tend to sap quite a bit of battery life. Leaving them plugged in when they are not required will shorten the amount of time you have on it substantially.

4. Dim the Lights

Most laptops these days have some sort of energy saving mode – All allow you to do it manually whilst some have predefined energy saving modes. These include dimming the screen display & dimming backlit keys.

5. No Screensaver

This is quite simple. Screensaver keeps everything running when the device could be Hibernating or going to sleep.

6. Sleep Vs Hibernate

If you’re on battery, allow your Laptop to sleep or hibernate after 2-5 minutes of inactivity. Might by a nuisance to log back in but you will get more out of it. Hibernate is a better option than sleep. In the Stand By mode (or sleep mode), the computer turns of the hard drive and the display but memory remains active while the CPU slows down. This draws on the battery. In contrast, hibernation mode is better because the computer saves the current state and shuts itself down completely thus saving power.

7. Multi Tasking

Whilst on Battery, try to keep the multi tasking as minimal as possible. Open one or two programs concurrently to get the most out of it.

8. Clean it

Keep your laptop clean and you will find that it will run much smoother. The air vents underneath and around your laptop sucks in air to cool the CPU and the other components. Over time the build up can be quite substantial. You can clean using compressed air – the laptop may need to be opened to complete this effectively – Contact Tech Helper).

9. Memory Effect

A problem more for the older Ni-MH batteries than for Li-Ion batteries on which most modern laptops run. Memory effect relates to the loss of battery charge when they are repeatedly recharged after being only partially discharged. It can be prevented by discharging the battery fully and then completely recharging it. Li-Ion batteries on the other hand have no problems with partial discharges and re-charges and complete discharge is never recommended for this type.

10. Use the Right Adapter

Ensure that the adapter you use to charge the laptop battery is an original one or one with the correct specifications. A mismatch in the wattage could cause an overload thus damaging the laptop and the battery.


11. Keep away from the Heat

Don’t pack your laptop away in a backpack or other enclosed space when the battery is still warm, trapping the heat. A battery that’s frequently hot to the touch will lose life a lot faster than a battery that isn’t constantly being stressed.

12. Don’t leave your battery on constant Charge

Don’t charge your laptop constantly. If you only occasionally take your laptop away from a power outlet, but leave it plugged in to charge 24/7, you’re leaving your laptop in a state of perpetual charge at the 100% point — and that is bad for the battery’s long-time health.

13. Run your battery down

If you tend to use your laptop mainly at your desk, exercise your laptop battery by running it down and recharging it once or (even better) twice a month.
