How Often Should I #Charge My #Laptops #Battery to Prolong Its Life?
Lithium-ion batteries are different from older, nickel-based batteries (which suffered from a nasty memory effect not present in lithium-ion batteries). Charging them incorrectly can decrease their lifespan. Most lithium batteries should last you a few years, but improper care can decrease that lifespan, meaning that your battery will be unable to hold a chargeâor unable to hold as big a charge as it used toâquicker. So, to clear things up, hereâs how to actually extend your batteryâs health as much as possible.
Perform shallow discharges Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. Discharges to 50% are better for your batteryâs long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Donât leave it fully charged. Similarly, lithium-ion batteries donât need to be charged all the way to 100%. In fact, theyâd prefer not to beâso the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, donât leave it plugged in. This is something most of us do, but itâs another thing that will degrade your batteryâs health.
Fully discharge it once a month. This may seem contradictory, but hear us out. While lithium-ion batteries shouldnât be discharged regularly, most modern batteries are whatâs known as âsmart batteriesâ, which means that they can tell you how long you have until your battery dies (e.g. â2 hours, 15 minutes remainingâ). This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.
Most people overlook this one. Excess heat is not only bad for your processor (and your lap), but your battery as well. Once again, see the table from Battery University âwhich you can click on for a closer viewâa hot battery will degrade in health much quicker than a cool one. As such, we highly recommend using a laptop stand, like one of the many DIY options featured at Lifehacker. When it comes to your phone, check out previous Ask Lifehacker on keeping your phone temperature down.
Keep these things in mind and your battery will last longer. That said, remember that you donât need to be super strict about these things. Donât sacrifice practicality just to keep your battery aliveâif youâre in a situation where you donât have a charger, itâs okay to discharge it to 0%, or charge it up to 100% if you want to do so for a long plane ride. Remember that your battery is going to die in a few years, no matter what you doâeven if you just let it sit on a shelf. So donât go overboard: use your battery as you need it. But, if youâre just sitting at home or in a coffee shop, these guidelines will help you keep it healthy for as long as possible (and when itâs dead, check out what do to when your battery doesnât last as long as it used to).

How to Prolong Lithium-Based Batteries
Charging Lithium-Ion Batteries
Your Laptop battery will degrade considerably if your laptop is left plugged in when the battery is in fact actually fully charged. fixmypc.24ex recommends removing your battery completely from your Laptop, since you can still use the laptop without its battery pack when on mains adapter & therefore keep your battery as cool as possible, & in itâs best condition, thereby prolonging itâs life. The same advice applies to smartphones also.
