Is It Healthy to Charge Phone Overnight?

If you have a smartphone, you must have asked this question at least once. What will happen if we charge phone overnight? Will battery life decrease? Or will phone overload and explode? Is it dangerous?

In fact, there is a lot of misinformation about it. People think that overcharging their phone will damage their device, kill the battery or explode the device. So what’s the truth? What happens if we leave the phone on charge overnight?

What Happens If I Charge Phone Overnight

These questions persisted for years, people believed that charging the phone for a long time would damage the battery. While this is rare on older devices, it’s no longer available today. Today’s smartphones and batteries -in short technology- have developed enough to take precautions. So you can charge the phone overnight, because when phone already fully charged, device cuts off the current and charging process is stopped.

Even if you charge phone for 10 hours, nothing will change. After the battery is full, charging stops.

But there are more options for your battery health that you should consider.

Lithium-Ion Technology and Charging Cycles

As you know, today’s smart phone batteries use lithium-ion technology. Lithium-ion battery (Li-ion) is a kind of rechargeable battery. They have been used in electronic devices for years. An advanced new version of this is Lithium polymer (Li-Po) batteries. They are smaller, lighter and easier to make than Lithium-ion (Li-ion) batteries.

Both are used today and both have advantages and disadvantages. Li-po batteries charge faster and they are newer, but have a lower capacity. Li-ion batteries, on the other hand, are more durable, but their life begins to expire from their production. In the smartphone part, both are considered the same, it’s up to the manufacturer’s choice. However, there is a situation like this in both batteries, charge cycles.

Basically Li-ion and Li-Po Batteries

If you are considering the battery life of your device, then this part is important. smartphone batteries have a certain charging range (20-80%). If you go above or below these values too many times, your battery life will decrease (in the long run). If you are obsessed with phone battery health, you can try to stay between these values. Don’t charge above 80% charge level and don’t discharge below 20% charge level. It will benefit your battery health in the long run. Going above these values doesn’t mean that it will kill your battery or damage the phone. Only battery life will decrease a little faster.

However, we don’t think it will make as much of a difference as the enduser can feel. Because lithium batteries already have a certain life and this will decrease eventually, this cannot be prevented. So trying to stay between these values won’t doubles your battery life, you’ll just have difficulty.

Phone Charging Tips

Instead of wasting time with these questions, let’s take a look at more useful topics. For example, don’t expose your phone to constant overheating for your battery health. Use original charger and cable, avoid fake accessories. Protect your device from sudden temperature changes (extreme cold – extreme heat). If possible, try not to use the device while charging.
