Points to Consider When Purchasing Laptops with Good Battery Life

Generally, people look out for CPU and graphics when purchasing laptops. People also pay attention to memory, storage, and display properties.

Seldom do they check out the battery particulars.

Similarly, manufacturers do not advertise much about the lasting battery power, with this specification included somewhere in the bottom rungs.

However, battery life is a critical aspect of the laptop’s performance. It is the primary significant feature that distinguishes a computer from a desktop PC.

Yes, one agrees that the performance of the battery depends on your usage. If you use the laptop for heavy-duty activities like video and photo editing, and gaming, etc., the battery can drain out quickly.

In comparison, the batteries last longer when you use the laptop for light activities like using MS Office tools or browsing the internet.

Similarly, using Bluetooth can also drain the battery much quicker than it usually does.

Research has shown that more than 85% of manufacturers overstate battery performance when advertising.

They provide these figures with a rider “under testing conditions.” No one knows what the testing conditions constitute. They are often unrealistic.

In a way, the manufacturers get away with it because very few people use MS Office continuously for 12 to 14 hours at a stretch.

However, the manufacturers cannot lie about battery specifications. These specifications are printed on the battery. Let us now decode them to understand the jargon better.

The following paragraphs will help you be comfortable with the terminologies and also calculate your laptop battery life.

The Formula

  • Check out the battery specification in Watt-hours. Manufacturers provide them as Whr or Wh.
  • Divide this number by the expected wattage. Generally, a computer should consume 10 to 15 watts under regular use. Note that heavy-duty activities can consume more Power.

For example, if the battery specification is 100Wh, the battery life should be between seven to ten hours (Divide 100Wh by 10 or 15).

Remember that these are approximate figures. One should also factor in issues like voltage drops at the end of the charge.

Estimate the Wattage

The question on your mind would be as to how to estimate the laptop wattage. Though it is a tricky affair, we can do so.

The wattage depends on the load. The higher the load, the higher the wattage. Therefore, the battery consumption is also the highest.

Intensive gaming is a full load scenario. A gaming laptop under a full load consumes around 65 to 90 watts.

Therefore, a fully charged battery should not last more than one to one and a half hours when gaming at high settings.

This table should make it simple for you

  • Intensive Gaming or Video Rendering – 60 watts to the maximum
  • Casual gaming – 40W to 60W
  • Video or photo editing – 30W to 40W
  • Watching HD Video online – 20W to 30W
  • Watching HD Video offline – 15W to 20W
  • Web browsing, using MS Office, playing music – 10W to 15W
  • Minimum wattage with the screen in the ON position – 8W to 10W

Though we have listed out the activities, in brief, various other factors decide the power consumption.

You can look at the higher ranges of the estimates listed above if you do the following.

  • Leave various applications running in the background
  • Use a laptop with dedicated graphics card
  • Have the screen brightness at the highest level
  • Use other devices like headphones, or printers
  • Screen size of more than 15 inches

Finding the Watt-hours

Manufacturers include the Watt Hour statistics on the specification sheet.

If you find the figure in mAh or Volts, you can use the online calculator and convert to Whr.

(The formula is Whr = mAh x V/1000)

Generally, you do not find ratings to go above 100Whr because the manufacturers have to comply with Lithium-Ion Flight Restrictions.

Airlines do not generally allow laptop batteries with a rating above 100Whr.

You can also find out the Whr rating of a battery using Windows 10 and macOS. Though the following lines could appear technical, they can be useful.

Windows 10

  1. On Windows 10, search for ‘cmd’ and click “Command Prompt.” (Admin Mode)
  2. Type powercfg/batteryreport
  3. Check out battery-report.html that you can open in a web browser.
  4. Look for the Design Capacity and divide it by 1000.
  5. Generally, the Design Capacity and the Full Charge Capacity should be the same. If there is a difference, it indicates that the laptop battery has worn out.

macOS

  1. Hold the option key and click the ‘Apple’ menu.
  2. Select ‘System Information.’
  3. Navigate to Hardware and click on Power
  4. Check out the Full Charge Capacity in mAH and Voltage in mV.
  5. Use the calculator to arrive at the Whr (Formula as shown above)

Tips to extend the battery life of your laptop.

The following tricks should help you get the best out of your laptop battery.

Reduce your screen brightness

The screen consumes a significant chunk of your battery power.

Reducing its brightness can help conserve battery life. Use the function keys on your laptop to reduce the intensity.

Change the power settings according to the usage.

Windows 10 comes with excellent power features that help to optimize battery life.

On the Start Search box, type out, “Power Options” and choose “Power Saver.” Using sleep mode intelligently can also save Power.

Switching off Wi-Fi can save Power

Wi-Fi drains the battery substantially. When not connected, Wi-Fi option searches for networks, thereby drawing additional Power from the battery.

Switching off the Wi-Fi when not required saves Power.

Use peripherals only when necessary

Plugging in peripherals like USB devices, mice, webcams, and others consumes Power.

Hence, it is advisable to use the laptop trackpads instead of the USB mouse. You should also consider shutting off the in-built webcam when not in use. Turning the speakers to mute will also save Power.

Your disc drives consume Power

Having a CD or DVD spinning inside your laptop consumes Power. Hence, it is better to eject these discs when not using them. It can save Power. Nowadays, laptops do not come with DVD and CD drives.

Use specific Hardware

Generally, laptops do not last for the entire day. Laptops today come with six-cell batteries and even 12-cell batteries. A suitable alternative is to use a portable laptop battery chargers. Some laptops can also be recharged using power banks.

Disable unnecessary features

Windows 10 offers various in-built features that are not always necessary. Disabling them can help extend battery life.

Dsiable Startup Programs

Take care of your battery

One should ensure not to discharge the Li-ion batteries completely. Generally, laptops come with a warning system when the battery level drops below a specific figure, say 20%.

One should plug on the charger and start charging the battery immediately. It can save your battery from early wear and tear.

Use Rapid chargers

Many laptops come with rapid-charging facilities that can help recharge the batteries up to nearly 80% in a short time. Using such chargers ensures that your battery does not drain off completely. You can get a quick recharge done that could last for valuable time.

Have more RAM

Multitasking can drain the batteries. One solution is to have more RAM in the laptop. Today, laptops are available with expandable RAM. It can help conserve energy.

Frequently Asked Questions

1. Which is the ideal way to use a laptop battery?

The best way to use a laptop battery is to ensure that it does not drain completely. The ideal level is to maintain the laptop battery at a level between 40% and 80%. Laptops come with battery level indicators that automatically switch off unnecessary applications when the battery level reaches a specific level, say 20%. One should plug in the charger when it reaches this level.

2. Is it right for me to keep the laptop plugged into the charger at all times?

No, it is not advisable to keep the battery plugged in at all times. It can generate sufficient heat that could harm the battery. Therefore, one should unplug the charger after recharging the battery. One can always use the charger again when the battery level dips below 20%.
