During hot weather, not only do high temperatures affect your energy levels, but they can also have a negative impact on your electronic devices. Issues such as battery swelling, screen dimming for protection, processor slowdowns, and charging difficulties can arise. However, adopting a few simple practices can help prevent a heatwave from causing damage to your devices.
To safeguard the gadgets you rely on, particularly during the scorching summer months, follow these tips:
Your smartphone is the most vulnerable device when it comes to heat exposure, whether it’s left on a sunny table, held in a sweaty hand, or placed face-up on a car seat. Direct sunlight is the main culprit. When outdoors, seek shade before using your phone and position the screen away from direct sunlight. Avoid leaving your phone on the dashboard or passenger seat of a parked vehicle, as cabin temperatures can rise rapidly.
Adjusting the screen brightness is crucial. High brightness levels under glaring sunlight put extra strain on the battery and processor, causing them to generate more heat internally. Dim the display as much as possible or enable auto-brightness. If your device starts struggling, activating Airplane Mode can help by shutting off cellular modems and 5G, which are major heat producers.
When it comes to charging, remember that charging itself generates heat. It’s advisable to steer clear of wireless charging pads during hot weather. These pads can generate significant heat directly against the back of your phone due to their inefficiency. Instead, opt for a standard, low-wattage wired cable. If your phone feels hot while charging, unplug it immediately.
If your phone feels excessively hot, remove its protective case. Thick silicone or rugged cases can trap heat, acting like insulation. Allowing the back of the phone to breathe helps dissipate heat.
Laptops and tablets face similar heat-related challenges as phones, but their larger size means they can trap even more heat. Avoid using a laptop on a soft surface that blocks its vents. Ensure there is ample clearance around the air intakes to allow fresh air to flow in and prevent warm air recirculation. When using these devices outdoors, place them on a hard, flat surface for proper ventilation.
Switching from performance mode to a balanced or power-saving profile can reduce the workload on the processor and graphics, minimizing the amount of hot air the cooling fans need to expel. Close unnecessary browser tabs and background applications. For tablets, dim the screen, avoid demanding games, and remove the case if possible to allow the device to dissipate heat.
Smaller devices like smartwatches, fitness trackers, and wireless earbuds are often overlooked but can be sensitive to high temperatures due to their small batteries. Store them in a cool, shaded area when not in use. Charging cases for earbuds also contain batteries and should not be left in direct sunlight to prevent damage.
Devices like power banks, handheld consoles, and Kindles contain lithium-ion batteries that degrade in high temperatures. Avoid storing them in tight pockets where body heat can elevate the temperature. When carrying multiple devices in a bag, ensure there is space between them to allow for proper air circulation and heat dissipation.
During a heatwave, the electrical grid can experience strain, leading to voltage fluctuations that can be harmful to sensitive devices. When charging valuable electronics, use a quality surge protector to safeguard them from sudden voltage spikes. Investing in a reliable surge-protected strip is more cost-effective than replacing damaged equipment.
If your device shows a temperature warning or feels excessively hot, avoid these common cooling mistakes:
Modern electronics are designed to safeguard themselves by slowing down or shutting off when they reach unsafe temperatures. In such cases, it is best to remove the case, power down the device, and allow it to cool down in a shaded and well-ventilated area.
