Are Phone Cases Bad for Heat? Tips on Balancing Protection and Temperature


We live in a modern age in which we need the support of technology to function successfully. In this period in which we exist, our best friends are smartphones that support us in literally everything. If it weren’t for smartphones, we would forget a large part of our responsibilities, be late, fail to complete everything, etc. That’s why we need to take care of them.

Our beloved smartphones are extensions of ourselves, holding our memories, connections, and entertainment in the palm of our hand, hence the need to take more care of them. But like any hardworking machine, they can get hot under the collar, sometimes literally. And while we shield them with protective cases, a nagging question arises: are phone cases bad for heat? Phone cases are a great way to protect them from scratches or breakage, but they are a very bad way to give them room to overheat.

The answer to the question about overheating of phones, as with most things in life, isn’t a simple yes or no. It’s a nuanced dance between materials, design, and usage habits. But no matter what we take into account, phones sometimes overheat under the influence of several factors that we can or cannot control. This topic is interesting and we need to take a good look at it. Let’s delve into the science behind phone heating and explore how to strike the perfect balance between protection and cool running.

Why do phones heat up? Answers and reasons for this question


Phones are small machines that are constantly in the process of working, even when they are locked. This alone causes the phones to occasionally heat up. Every process, from streaming videos to playing games, generates heat. This heat needs to escape to prevent internal components from overheating and, well, melting down. Many believe that it is because of the masks, but often if a good enough mask is chosen like the well-made masks from Orase Phone Cases, it does not happen. Manufacturers design phones with heat sinks and thermal paste to dissipate this heat, but sometimes, it’s just not enough, so it’s good to choose a mask that won’t lead to overheating.

  1. When it comes to your smartphone overheating, you need to know the following important things that might help you prevent overheating if you are not doing them:
  • Tasks that are demanding can very easily lead to overheating – pushing your phone to its limits with graphically intense games, high-resolution video editing, or extensive multitasking can overwhelm its cooling system.
  • Hot weather and direct contact with the sun can also increase the temperature – Leaving your phone baking in the sun is like putting it in a sauna. Direct heat exposure significantly increases internal temperatures.
  • Phones heat up easily while on the charger – The charging process itself generates heat, and using low-quality chargers or fast-charging options can further exacerbate the issue.
  • An update that has not been done, a bad battery and a hardware problem also cause heating – In some cases, a malfunctioning battery or internal component can be the root cause of excessive heating.

Are masks suitable for phones or is it still better to use the phone without a mask?

Since over the years, there has been talk about whether phones are protected enough, but also whether those protective masks are good, it’s time to talk a little more about this second part. Do they trap heat, making things worse? The answer depends on the type of case, what kind of device you have, the quality of the mask, and also many other things that we have detailed below.

  1. a) Big cases make phones heat up – Thick, plastic cases, especially those made of non-heat-conductive materials like rubber, can act as insulators, trapping heat inside the phone. This causes heating reduced speed, and performance and can lead to serious problems with the phone if it happens for a long time.
  2. b) Thin and elegant masks – Thin models made of materials like metal or certain types of plastic can aid in heat dissipation due to their better thermal conductivity. As such, they are not a problem (mostly) for phones.
  3. c) Cases with space for ventilation – Some cases come with built-in vents or channels specifically designed to allow heat to escape. By doing so, the smartphone itself can work to reduce the temperature and not slow down the operation of the phone.

Several ways to keep the temperature of your smartphone low


Whether you rock a case or prefer the naked phone experience, here are some general tips to keep your phone’s temperature at a low level, and at the same time to have a phone that can help you complete all your tasks during the day:

Tip No. 1: Determine how long and when you will use your phone

The phone is not a toy, nor is it something that any of us could do without. From there it is necessary to reduce the time of use. Avoid pushing your phone to its limits for extended periods. Take breaks, close unnecessary apps, and lower screen brightness when possible, why is it so easy and simple to reduce the temperature of the phone?

Tip No. 2: Keep it in places that are not in direct sunlight

Keep your phone out of direct sunlight, especially on hot days. The heat can cause battery problems, screen problems, and many other problems, all of which may not be the phone case’s fault.

Tip No. 3: Use only chargers that are compatible with your phone

Stick to the charger that came with your phone or opt for certified alternatives to avoid overheating issues. We know that chargers today can be expensive when we need to replace them, but it is not an option to get a fake charger that could make the phone worse in terms of heat.

Tip No.4: Monitor the condition of your battery

The battery has a certain period during which it works at 100% capacity, but over time it loses its capacity and does not work as well as it did before. Regularly check your battery health to check the condition and react. A degraded battery can generate more heat, so consider a replacement if needed.



Choose the mask that best matches your phone – If you use a case, prioritize thin, well-ventilated designs made of heat-conductive materials like metal. Never buy from those thick masks made of bad materials that can only make the phone hotter and thus slower.


Phone cases are the best protectors and friends of the phone. From this, we can conclude that they can be primarily protectors of the phone’s condition, and on the other hand, they can also be phone warmers if they are not protected well enough. Therefore, choose a suitable mask that will not heat the phone, but also apply the tips that we have brought you today to avoid this problem with heating the phone.
