What devices are susceptible? -

Any device with a lithium-ion battery can be at risk. This includes smartphones, tablets, portable chargers, and more.

Is it likely that your smartphone will explode? -

The chance your device will explode or catch fire is said to be "slim."

Why do devices catch fire or explode? - There are multiple reasons a device might catch fire or explode but usually, excessive heat in the lithium-ion battery is to blame.

Why does heat destroy up the battery? -

If a charging battery or overworked processor becomes too hot in too short a time, it can ruin the chemical makeup of your phone. In batteries, this can trigger a chain reaction known as a thermal runway, which potentially causes the battery to generate more heat and even cause a fire or explosion.

Other reasons: physical damage -

If you drop your phone or bend your phone excessively, it can disrupt the battery.

Phone in the sun -

If you leave your phone in direct sunlight for too long, it can overheat and possibly lead to a fire or explosion. Even if that doesn't happen, it could still negatively impact the battery and phone.

Something out of your control -

In general, it could be outside your control as batteries degrade over time. If you've had your device for many years, the internal components may fade thereby leading to swelling and overheating.

Warning signs - If you hear hissing or popping sounds coming from the phone, or if you smell burning plastic or chemicals, it may be damaged and close to exploding.

Excessive device heat -

Always be aware of excessive heat coming from your phone, especially if you're charging it. If it's hot to the touch, immediately unplug it.

Swollen battery -

If your phone has been damaged or internal parts degraded, then a swollen battery can happen. Be on the lookout for changes in the device's shape such as a protruding or enlarged seam, or anything causing the phone to no longer sit flush against a flat surface.

If you’re concerned -

Most modern smartphones no longer let you remove the battery, so, if you are concerned first turn it off then take it to a service provider.

Can you prevent your phone from overheating? -

If it's a phone manufacturing defect, unfortunately, there isn't much you can do.

How to save your phone battery -

Most devices won't go up in flames after one fall but to protect them it's best to use a case. Look for one with a lip around the edge of the phone. Even if it's a cheap case, it's better than nothing.

Avoid extreme temperatures -

It's more obvious to avoid heat when it comes to your phone but what about cold? Phone batteries are optimized to work within 32°F to 95°F (0°C to 35°C). If you regularly expose the phone to harsh conditions it can cause damage.

What does this mean? -

This means that you should never leave your device in direct sunlight for long periods especially when charging. Additionally, avoid freezing temperatures whenever possible.

Dont cover your phone while it’s charging -

If your phone is charging, never slide it under your pillow or a blanket as it can overheat and cause problems.

Best option -

The best idea is to place your phone on a flat, hard surface such as a table, desk, or nightstand especially when it's connected to a charger.

Practice good battery hygiene -

It's recommended to keep your phone charged between 30% and 80% most of the time. Many of us want the battery to be always at 100% but it's not needed. Also if you can, don't charge it overnight.

Should you be worried? -

Being worried isn't really necessary. It can take several years for the battery to naturally deteriorate. If you switch out phones every couple of years, everything should be fine.

Use the right charger -

Your device needs a certain voltage and current to charge correctly. It's advised that you only use the charger your phone came with.

Don’t mix and match -

You shouldn't mix and match cables and power bricks or squares because they might have different units or wattage levels. It can be tempting to buy a cheaper charger but it's also a great way to ruin your battery.

Third-party chargers -

If you absolutely must buy a third-party charger, be sure to stick with a known brand such as Anker. Avoid no-name companies.

Take care of your cables -

Once the charger is purchased, be sure you're taking care of the cables. Damaged wires can lead to charging issues and cause a fire themselves. 

© Shutterstock

Best practices -

Avoid wrapping wires tightly and always unplug the charger from the plug instead of pulling or yanking it out by the cord.

Look out for malware -

If your phone or mobile device becomes infected with malware you should take it to a provider and let them know what happened. This spamming of your phone could cause the battery to heat more than usual.

Are Apple and Android’s susceptible? -

Apple devices are generally safer due to the App Store’s strict review process and closed ecosystem. While Google Play has security measures, its openness allows some malicious apps through, and sideloading increases risk. Caution is advised when downloading apps on Android.

Only use authorized parts -

If you're planning to try your hand at some device repairs, be sure to only use authorized parts instead of a third-party supplier, especially with the battery. A poorly made battery can be a fire hazard just waiting to happen.
