Our smartphones are our portals to our digital worlds. They are practically extensions of ourselves and our lifelines when we’re out and about.
However, no matter how vital a smartphone is in our daily lives, it is useless if it runs out of juice. That’s why the last thing that you need is a less than optimal, or worse, a dead smartphone battery.
Unfortunately, many people are making this one simple mistake that could degrade their smartphone batteries sooner.
Is charging overnight safe?
We’ve warned you about the dangers of overcharging your phone. This usually happens when we go to bed, plug our smartphones in then leave them charging overnight.
If you’re like me, there’s nothing like waking up to a smartphone charged to 100 percent, ready to take on the day’s work! But can this habit really diminish our smartphone’s battery capacity?
The good news is that modern smartphones have built-in chips that keep them from overcharging. They’re smart enough to stop taking in excess electrical currents once it reaches a full charge. Even top-shelf quality chargers, like the ones from Anker, have these chips built in to prevent it from releasing more power than required.
The bad news is that due to the inherent properties of lithium-ion batteries – the current go-to technology for smartphone batteries these days – they are destined to decay and fail from the moment they’re initially charged since they have a limited number of charging cycles.
Why your smartphone battery’s charging cycles matter
Right off the bat, smartphone batteries are gradually losing their capacity with each charging cycle. This is why people typically start noticing a significant degradation in their smartphone’s battery capacity after two years of constant discharging and recharging.
By keeping your phone on the charger overnight, every night, while you’re sleeping, you’re keeping it on the charger for about three to four months a year. This means, while plugged in, it’s always in a state of discharging and recharging, slowly using up another cycle.
To postpone the inevitable end of your smartphone’s lithium-ion battery, it’s best not to wait until your gadget is close to 0 percent battery charge before plugging it in. Battery experts say that full discharges wear out lithium-ion batteries sooner than partial ones. It’s recommended that you wait until your phone is around 35 percent to 40 percent before plugging it in.
Squeeze more life out of your smartphone battery
Basically, if you want to squeeze more life out of your 2-year-old smartphone, it’s important that you wait until a certain percentage before plugging it in, resist charging it overnight and more importantly, avoid exposing it to extreme heat at all costs.
