Should you leave your smartphone plugged into the charger overnight?


It’s an issue that has plagued humanity since the dawn of the mobile phone. We use our trusty pocket computers so much that they rarely get through a day with any power left. Many of us plug them in at night and fall asleep, content in the knowledge that we’ll wake up to a fully charged device.

But is it really safe to leave our phones plugged into the charger once they’re fully charged? Is it damaging the battery — or shortening its lifespan?
There are lots of myths and questionable ideas on this topic. You’ll find the Internet awash with opinions masquerading as facts. What’s the truth?

Overnight charge

The myth about overcharging your phone is a common one. The amount of charge going into your device shouldn’t be an issue as most are smart enough to stop taking a charge once full, just topping up as needed to stay at 100 per cent.
The problems occur when the battery overheats, which can cause damage. To avoid this it’s best to remove any case on your phone when charging over night. It’s also best to leave the phone on a flat, hard surface so the heat can dissipate easily.
So it’s perfectly safe to charge your phone overnight, just make sure it doesn’t suffer from overheating.

While you can use any charger for a lot of phones, like Android devices, it’s best to use the official one. Chargers from the big brand names have been checked, checked and rechecked to perfection. Once you start using third party chargers you’re entering risky territory where you may end up damaging your battery without realising it.

Lithium versus nickel

You’re probably aware that the majority of today’s tech runs on lithium ion batteries. Years ago, batteries were primarily made of nickel like the Duracell and Energizer batteries you buy in stores. Nickel-based batteries exhibited a tendency to have a cyclic memory. If they weren’t given full charges in between cycles, they might “forget” their full capacity and remember the point to which they were last charged as being the maximum capacity. Many of us have never used nickel-based batteries in our mobile devices since the transition to lithium ion had occurred by the early 2000s.

LITHIUM ION AND NICKEL BATTERIES HAVE A FEW MAJOR DIFFERENCES

Fortunately, lithium-based batteries didn’t suffer from the memory phenomenon often exhibited by the nickel batteries. Lithium batteries played a major part in the mobile phone revolution. For one thing, they’re able to hold a lot of power while remaining fairly compact, which allowed mobile phones to become increasingly small and thin. Also, lithium batteries have a much better lifespan and recharge fairly quickly. The one caveat is temperature sensitivity.

Heat: The Silent (Battery) Killer

Now we get to the most significant threat to your lithium-ion or lithium-polymer battery, which is heat. Granted, batteries dislike the cold just about as much as they dislike the heat, but the latter is more relevant when it comes to leaving your device plugged into its charger overnight.

The charging temperature for lithium-based batteries — i.e., the temperature at which a battery is capable of receiving a charge — is 32° to 113°F. Meanwhile, lithium-based batteries can discharge at temperatures as low as -4°F. Fast-charging technologies work best at warmer temperatures between 41° and 113°F, with no charge capable of occurring when the temperature is lower than 32°F

There are a couple important things that these figures tell us. First, a lithium-based battery can discharge at temperatures far below freezing, so keeping them in your kitchen freezer won’t prevent them from self-discharging. Second, a lithium ion battery warms up as it charges. As it gets warmer, it charges faster. But since a battery can’t hold more than its capacity, after reaching a full charge the battery expends the excess power by giving it off as heat. Overnight charging becomes a problem when a battery has no way to reroute the incoming current after reaching its capacity.

Fortunately, there’s a solution to this problem.

Batteries used in mobile devices today are still mostly the same as they have been for almost two decades, but the devices that they power have become much, much smarter. Nowadays we have less to worry about when it comes to the battery health because power optimization has been put on the shoulders of the software running these devices.

Thus, we get to the answer of our main question: Should we leave our smartphones plugged in overnight? The answer to this question is a resounding sure, why not?

OUR MOBILE DEVICES HAVE GOTTEN MUCH SMARTER OVER THE YEARS

As we discussed above, the main danger in leaving your smartphone plugged in overnight was allowing the battery of your device to get hot and remain hot through the rest of the night. However, our mobile devices have gotten much smarter. They can stop charging when the battery has reached its full capacity and begin using the connected charger as its primary power source, allowing you to wake up to a fully-charged battery while your phone remains powered on through the night. It’s a pretty sweet deal.

However, that’s not to say that your charging habits can’t have an effect on the health and longevity of your battery. While you’re not at risk of overheating your battery by leaving your phone plugged in overnight, we’ll still walk you though a number of tips you can incorporate into your charging habits to keep your device’s battery in tip-top shape.

Smartphone battery charging best practices

Each lithium-based battery is capable of a finite number of charge-and-discharge cycles. With each cycle, the capacity of the battery is very slightly reduced, so we want to avoid as many complete cycles as we can. To do this, try to keep your battery’s charge level between 40 percent and 80 percent power. Of course, this won’t always be possible, but try not to let your phone’s battery level get below 40 percent too often and keep the number of complete top-offs to a minimum.

Try not to use fast charge every single time you charge your phone. Most fast or rapid charge systems cause the battery to become hot, which we now know is bad for your battery. If you’re using the fast charge option every single time, the battery is getting excess heat more often than it should, resulting in a shorter lifespan.

Earlier in this discussion, we mentioned how lithium ion batteries don’t suffer from the same cyclic memory of nickel-based batteries. While that’s true, the internal power meter in your smartphone — the part that determines the battery’s current power level — can sometimes get thrown off. You can recalibrate by doing a full discharge-and-charge cycle: Use your phone until it dies. Once it’s dead, charge it to full capacity while leaving its power off. Finally, power your phone back on and make sure it reads as fully charged; if it doesn’t, power off and continue charging. Repeat this process once a month or so to make sure your battery is functioning optimally.

Wrapping up

The battery is one of a smartphone’s most important components; after all, a smartphone with a dead battery is little more than a paperweight. So it goes without saying that we surely don’t want to do anything that would damage our batteries and make them less efficient. Although there are some who still believe it’s a bad idea to leave your phone plugged in overnight, all signs point to overnight charging being a completely valid way to make sure you start your day with a full charge on your smartphone.

What do you think about overnight charging? Have you ever noticed a difference in the capacity of your device’s battery after charging overnight? Do you agree or disagree with our findings? Sound off in the comments below with your thoughts.
