iFixit recommends draining your phone or laptop completely to calibrate the battery gauge.

There is no “memory” to reset in lithium-ion batteries, unlike the nickel-cadmium batteries of yore.

The only time you need to let a battery discharge completely is when you install a new battery in a computing device, and it’s for the sake of the device, not the battery.

Another post shows off testing by site sponsor Cadex, with a set of cellphone batteries dropping from 88-94 percent capacity to 73-84 percent capacity after just 250 full discharge-recharge cycles. “A deep discharge with a full recharge causes undue stress to any battery,” reads one. That’s the message of the many warnings littered throughout Battery University. It’s not just sitting at zero that hurts, but the full recharge, too. Keeping your device between 40 and 80 percent is advisable, but letting it get to absolute zero is a small tragedy. But keep in mind, that temperature is inside the laptop if that’s how hot it is in the air, it’s certainly hotter inside. 86 F (30 C) is the benchmark Battery University recommends to stay under. A battery kept at a wintry 32 Fahrenheit (0 Celsius) retained 94 percent of its charge capacity, while a laptop at 104 F (40 C) held 65 percent. A chart on Battery University (third chart down the page) shows lithium-ion batteries kept in different temperatures for one year. When you’re not using your laptop, keep it someplace cool, away from sunlight or heating vents. Take a look around the laptop, see where the vents are, and avoid blocking them. So keep the lid open for a while after the laptop runs hot, and keep it off your thighs, or pillows, or laptop desks that surround it with pillows. As our CEO Kyle Wiens told Wired UK in 2013, extreme heat causes physical expansion and chemical changes in batteries: “Too much heat to the battery over time, and the battery isn’t going to last as long.”

Because of their compact size and lack of large cooling fans, laptops can get quite hot, to the point of causing gradual skin burns, or “toasted skin syndrome.” If non-toasted skin weren’t incentive enough, the heat your thighs create by trapping heat and blocking vents is also killing the laptop battery. Laptops are not good to keep on your lap. Keep It Ventilated, Store It Somewhere Cool Dewey is cute, but not great for battery life. When you combine a battery at maximum capacity with serious heat exposure, that’s when it starts taking damage and losing life. This could be because you’re doing a lot of compiling, rendering, or other intensive work, or because it’s hot where the laptop is used, due to sunlight, exhaust, or other factors. The exception is if your laptop runs hot. Once the battery hits 100 percent, most modern laptops stop charging, and the power is diverted to the system instead.ġ6 bits and basic opening tools will get you into standard devices.

It’s only as bad as charging it once, to 100 percent, in the first place. Keeping your laptop plugged in regularly, with the battery charged to 100 percent, isn’t slowly killing it, despite what you may read. If that last piece advice made you feel guilty, don’t worry about being so basic with your laptop use. If You Leave It Plugged In, Don’t Let It Run Hot Image by Daniel Aleksandersen / Ctrl blog

Check your laptop manufacturer’s support software to see if you have a charge limiter. Lenovo’s Vantage app for ThinkPad laptops allows for setting a maximum battery charge threshold, and some Samsung and Sony laptops do as well. Some laptops offer a viable solution to the plugged-in problem. A laptop battery charged to 80 percent might make it 850-1,500 cycles. A battery charged to its extremes, from empty to full, can make that trip 300-500 times before burning out, according to Battery University, the highly informative, if archaically organized, depot of battery tips and testing. But if battery life is generally not a problem for you, or you usually have a charger handy, these are the ideal limits to stay inside. This may not be practical for road warriors, the overscheduled, or those who suffer from charge anxiety. Unfortunately, it’s also the toughest to follow. Using it this way is the best and most obvious way to extend the longevity and charge capacity of your laptop.

When it’s time to recharge it, top it off to about 80 percent, if it has decent capacity and you can live with the uncertainty. If you use your laptop away from its charger quite often, try to keep it above 40 percent charge.
