Charging your laptop on the go is a challenging task. You might know how you can enhance the battery life of your laptop, but did you know how you can actually extend the lifespan of your laptop's battery.

In fact, many users keep their laptop plugged into the charger all the time even after the device is fully charged. Some people do not believe in this and they use it on battery power.
If you are confused on how exactly your laptop should be used, you will find this content very helpful. Check out how you can improve the lifespan of your laptop's battery from here. Know the Battery of Your Laptop Laptop batteries are of two types - Li-Ion and Li-Po. Though both are different technologies, they function almost in the same way with electrons moving to create power. This flow keeps the battery healthy. These are true for any modern laptop battery. You should not overcharge the battery by plugging it all the time. Once it is charged fully, it will cease charging and it will not take in power only when the charge drops to below a specific level. Discharging the battery fully will damage it. If the battery is discharged for a long period, it might not recover.

Lithium batteries are vulnerable to these The lithium batteries in laptops are highly unstable. These batteries lose their capacity from the time they are produced. The factors that affect their lifespan are charging and discharging cycles, voltage levels, and high temperature of over 30 degree Celsius. It is claimed that low voltage levels and very high temperatures will affect the battery's lifespan when in isolation. Obviously, it is the worse when they join. Charging levels have to be noted The Li-Ion batteries charge to 4.20 V/ cell that results in 100 percent of the capacity. At this voltage level, the battery's lifespan will involve 300 to 500 discharge cycles.

But, at this time, the battery is just 58 percent charged and the runtime will be little more than half of a battery that is fully charged. Heating issue Elevated temperatures of over 30 degrees Celsius will shorten the battery's life irrespective of the other factors. It is a bad idea to leave your laptop in the car on a summer afternoon. When high voltage and temperature combine, the effects will be worse. Apart from the environmental reasons for the temperature rise, even the intense tasks such as video editing or gaming will increase the heat levels considerably. This is the same as using the laptop on a pillow with poor ventilation. Should you remove the battery from the laptop? If heat is dangerous, should you remove the laptop's battery when it is not in use? The answer to this question varies from one manufacturer to the other. For instance, Acer suggests removing the battery, but Apple doesn't. The power management setup in the laptop will handle all this. Some might reduce the power when there is no battery and some do the same when the better level is low. This will result in subpar performance. If you remove the battery, make sure it is charged between 40 to 70 percent and maintained at room temperature. Verdict You cannot find a great answer to this topic as the manufacturers are coming up with misleading solutions. Leaving your laptop plugged in will result in damage, but if you use it on AC power, you will find that the battery capacity has been reduced significantly after a year. If you use it on battery power, you will quickly get through the discharge cycles of the battery. The best solution to this is a compromise between the two - using it on battery sometimes and keeping it plugged on the rest. Make sure, your laptop does not get too hot.

All-Important Ports
Ports are to laptops what ice cream is to people. Limit them, and youâ€™ll be shocked by the Before and After shots.Other than the headphone jack, the MacBook has just one USB portâ€”and itâ€™s not even the kind youâ€™re familiar with. The size of a Tic Tac, the USB Type-C port is used to charge the laptop and attach peripherals, including an external display.Weâ€™ll get over the limited port situation just like we got over the disappearance of DVD drives. (Remember those?) But in the here and now, there are two issues.First, since the port is uncommon, you canâ€™t do things you take for granted, like plugging an iPhone into your computer with the regular USB cable. Second, one port just wasnâ€™t enough for me. The best solution? Purchase a hub with full-size USB ports and an SD card slot, like the $50 Hyperdrive USB Type-C 5-in-1 Hub.

Apple should take a page from HPâ€™s port playbook: The Spectre has three USB Type-C ports along its back, two of which are capable of handling more power than the MacBookâ€™s. And if you buy the Spectre from Best Buy, a USB-Type-C-to-regular-USB adapter is included in the box.

The Key(s) to Comfort
The MacBook and the Spectre represent the laptop stripped to its barest parts: screen and keyboard. Yet theyâ€™re not like the tablet-keyboard combos, which fail at the whole sitting-on-your-lap thing. The traditional clamshell design makes these a pleasure to useâ€”if you can get used to a few ergonomic shortcomings of their own.

The MacBookâ€™s sturdier, more attractive build is tarnished by a keyboard that looks like itâ€™s been flattened by a dough roller. To make the underside razor-thin, the keys were chopped off and redesigned with a mechanism that aims to recreate the feedback and bounce of real keys. It took some getting used to, but three months in, my hands were so comfortable, it felt a little weird going back to the MacBook Air.From the start, I loved the MacBookâ€™s large trackpad. Though itâ€™s just a flat, fixed piece of glass, small vibrations and a clicking sound fool you into thinking youâ€™re physically pressing down. It messes with your mindâ€”in a good way.

With the Spectre I felt at home on the keyboard in an instant. The keys are a normal height, with more surface area thanks to a 13.3-inch screen (versus the MacBookâ€™s 12-inch display). HPâ€™s trackpad, on the other hand, feels claustrophobic. I also repeatedly encountered issues with it, including jumping cursors and unregistered clicks. HP says it is working on a software update to fix the problems. The unfixable issue with the Spectre? The fact that it looks like it was designed by Kanye West. The only color option includes a gaudy gold logo and hinge that instantly attract fingerprints. On the other hand, I am entranced by HPâ€™s trippy new logo. Itâ€™s like a Magic Eye optical illusion. Does it say HP? Lip? Fiji?

Prioritizing Performance
Since thinner laptops have less room for battery, they tend to have less powerful chips. Yet the newest chips found in the MacBook and Spectre amp up the processing while remaining relatively efficient.

Apple recently updated the MacBook with the new Intel Core M processor, which is 20% faster than last yearâ€™s chip. I noticed it. The previous model took too long to open apps and multitask. The new oneâ€™s snappier at my usual routine of juggling multiple browser tabs and apps like Spotify, Microsoft Word and Slack. Slowdowns only start occurring when I throw more graphics-intensive jobs at it in Photoshop. (Iâ€™ve changed my mind. It could now potentially replace my three-year-old MacBook Air, though Iâ€™d like to see whatâ€™s next for the MacBook Pro before deciding.)

The Spectre is available with Intelâ€™s big-boy Core i5 and i7 processors. These can provide up to 25% more power than the Core M processors. In my tests, the Spectre was just as snappy as the MacBook at surfing the web and launching apps, but when it came to editing multiple, large images in Photoshop, the HP was far more cooperative.
