Here we can see, “Should I Leave My Laptop Plugged In All The Time?”
Is it better to keep your Laptop plugged in or use it on battery power? It seems the solution isn’t entirely straightforward.
At one point or another, all laptop users find themselves pondering an equivalent question: is it wrong to go away with your Laptop plugged the time altogether?
It turns out the solution isn’t entirely straightforward. So let’s take a glance.
Know Your Laptop Battery
There are two primary sorts of batteries utilized in laptops: lithium-ion and lithium-polymer. Although they’re different technologies, they function in broadly an equivalent way, generating power through the movement of electrons.
This constant flow is additionally needed to assist keep the battery healthy.
For both sorts of batteries, the subsequent statements are factual (at least as far as modern laptops are concerned):
- A battery can’t be overcharged. There is no danger of overcharging A battery if you allow it plugged the time altogether. As soon as it hits one hundred pc, it’ll cease charging and start again until the voltage falls below a particular level.
- Fully discharging A battery will damage it. Allowing the battery to become empty for an extended period can put it into a deep discharge state. this will be fatal—you might never be ready to charge it again. (You can try these methods to leap-start a dead laptop battery.)
So, supported this, can we conclude that you should leave your Laptop plugged the time altogether? Almost.
Things That Damage Lithium Batteries
The truth about lithium-based batteries is that they’re inherently unstable. They start to lose capacity from the instant they’re produced, and numerous factors hasten their decline. These include:
- Charge/discharge cycles. Every battery features a finite number of times it is often charged and discharged.
- Voltage level. The upper the charge level (measured in volts per cell), the shorter the battery’s life.
- High temperature, over 30 degrees celsius. This will cause irreparable damage.
The last two are those that we’re most concerned with here. A comprehensive study by Battery University highlights how voltage levels and high temperatures will shorten the lifetime of A battery in isolation, and even more once they combine.
Charge or Voltage Level
Lithium-ion batteries charge 4.20 volts per cell, which amounts to one hundred pc of its capacity. At this level, the battery will have a lifespan of 300-500 discharge cycles.
| Charge level (V/cell) | Discharge cycles | Available stored energy |
|---|---|---|
| [4.30] | [450-250] | [110%-115%] |
| 4.20 | 300-500 | 100% |
| 4.10 | 600-1000 | 85%-90% |
| 4.00 | 1200-2000 | 70%-75% |
| 3.90 | 2400-4000 | 60%-65% |
Every 0.10V/cell reduction within the charge doubles the number of discharge cycles until the optimum level is reached: 3.90V/cell, with 2400-4000 discharge cycles.
Unfortunately, at this level, the battery is merely around 60 percent charged. The runtime is going to be little quite half a fully charged battery.
Heat
And then there’s heat. High temperatures, typically classified as being over 30 degrees Celsius, will shorten the lifetime of A battery regardless of the other factors. Simply leaving your Laptop in your car on a summer afternoon may be a bad idea.
When you combine the strain of heat with the strain of high voltage, the consequences are even worse.
The Battery University study shows that A battery stored with a 40 percent charge at 40 degrees would see its capacity fall to 85 percent after a year.
| Temperature | 40% charge | 100% charge |
|---|---|---|
| 0°c | 98% (after 1 year) | 94% (after 1 year) |
| 25°c | 96% (after 1 year) | 80% (after 1 year) |
| 40°c | 85% (after 1 year) | 65% (after 1 year) |
| 60°c | 75% (after 1 year) | 60% (after 3 months) |
Charged to one hundred pc, the capacity falls to 65 percent under identical conditions. For a charged battery at 60 degrees, the capacity plummets to 60 percent in only three months.
The evidence seems clear. Keeping the battery permanently charged at one hundred pc will slowly shorten its life. Keeping it at one hundred pc and exposing it to high temperatures will shorten it much quicker.
And remember, these high temperatures aren’t just environmental. Resource-intensive tasks like gaming or video editing will considerably increase heat levels. Using the Laptop on a pillow or during a poorly designed case will also trap that heat.
For the sake of your battery, it is often a simple idea to repair an overheating laptop.
Should You Remove the Battery?
If heat is such a danger, it begs another question. Do you have to remove the battery altogether when using your Laptop on AC power?
This is not possible on the growing number of laptops that sport sealed batteries.
Where they’re replaceable, the solution seems to vary from one manufacturer to subsequent. Acer, as an example, says you do not need to remove the battery on AC power but should remove it if you are not getting to use it for several days. When Apple produced laptops with removable batteries, it advised against ever taking them out.
It all comes right down to the facility management setup within the Laptop. Some may reduce the facility when A battery isn’t present, even as some do when the battery level gets low. This might leave you with subpar performance.
If you are doing prefer to remove the battery, make sure that you store it properly. This usually means charged to between 40 percent and 80 percent and kept at temperature.
Should You Keep Your Laptop Plugged In?
Does leaving your Laptop plugged in ruin the battery? Yes, it does. On the other hand, so does charging it a day.
Curiously, the industry as an entire doesn’t seem to possess settled on one account the question about whether to use your Laptop on AC or battery power.
We’ve seen that Acer recommends removing the battery once you aren’t using it. Asus says you ought to drain the battery to a minimum of 50 percent every fortnight. But Dell says there is no problem leaving the Laptop plugged in in the least time.
Apple’s advice is not any longer on its website, but you’ll still read it online. The corporate recommends against leaving a laptop plugged the time altogether. Instead, it suggests:
“An ideal user would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing…”
Leaving your Laptop plugged in won’t cause short-term damage. Still, if you simply ever use it on AC power, you’ll almost certainly find that after a year, the battery’s capacity has been significantly reduced. Similarly, if you simply ever use it on battery power, you will get through the battery’s discharge cycles quicker.
So, the simplest solution is a compromise between the two: use it on battery power some days, and keep it plugged in on others. And whatever you are doing, you’ll want to make sure it doesn’t get too hot.
