Even with the rapid evolution of smartphone technologies, it’s safe to say that the smartphone overheating issue is not going away anytime soon. Through the years, we’ve seen practical demonstrations on just how phones overheating can be a dangerous affair leading to the damage of devices and affecting performance. Throughout the article, we’ll be exploring what really causes smartphones to overheat and a couple of solutions worth checking out.

The Why      

Why do smartphones heat up? Simple, because movement tends to generate heat. Because of all the miniature components in smartphones, most people to acknowledge that there are vast amounts of electricity going all around the device.

Engaging in activities like playing games takes a toll on the central and graphics processing units which are housed in a central system-on-a-chip (SoC). This explains the warm feel around the phone when we play games on our devices. Thus, there’s really no need to worry whenever the phone’s temperature is slightly higher than normal. It’s only until they become unreasonably hot that one needs to have some concern about the phone.

Avoiding Overheating

One needs to avoid exposing phones to hot environments, especially when they are fully charged. Fully charged batteries are likely to decay in terms of performance if they are exposed to heat stress.

The other way one can avert this whole situation is to take note of the depth of discharge concept. For optimal functioning, it is recommended to maintain the phone’s charge between 30% and 80%. When this is done over extended periods, one can get more bang for their buck since they’re less likely to need phone-battery replacements.

Importantly, one should never leave their phone charging overnight on a warm surface like on the bed or sofa, instead, try placing the phone on a cool surface in order to prevent overheating.

Recently, the Blackberry Z10 experienced a number of issues because of overheating issues, some of the corrective measures suggested was an upgrade in operating system because the phones had capable hardware.

Power Saving

The concept here is to avoid strenuous activities on the phone as much as one can. Minimizing the time spent on Bluetooth connections, using only stable Wi-Fi, and reducing the time spent on demanding videos and games, are some of the best practices for one to have.

Cases and Covers

While having cases and covers on phones can help protect them from mechanical damage and help preserve the phones resell value, these protective measures can at times inhibit the phone’s cooling abilities. Ideally, one should strip/expose regions of the phone to the air every once in a while, in order to allow the phones to breathe.

Some apps found in the Play Store and App Store can help manage some of the phone’s processes in order to conserve power and resources. Some of the handy battery management apps include Greenify, Battery Doctor,and DU Battery Saver.


Smartphones became a big hit because of all the customization most of them supported, plus, their excellent functionalities. However, in recent times, smartphones have been on the receiving end from some of what technology has to offer. Viruses tend to overwork smartphones and lead to data loss or eventual damage. To avert virus situations, we recommend checking out a number of anti-virus apps available in the market and avoid downloading and/or clicking links from dubious websites.
