Što učiniti ako vam telefon postane pregrijan tijekom ljeta?

As summer temperatures rise, smartphone users are increasingly encountering overheating issues, particularly during outdoor activities or while using their devices in hot environments. On August 1, 2026, reports highlighted how high ambient temperatures combined with intensive phone usage can lead to performance slowdowns, dimmed screens, and even complete shutdowns. This phenomenon is becoming more common as users spend extended time outdoors or in vehicles exposed to direct sunlight, prompting concerns over device safety and longevity. The problem begins when external temperatures exceed 30 degrees Celsius, especially when smartphones are engaged in resource-heavy tasks such as recording high-resolution videos, playing games, or using navigation systems. These activities generate additional heat, which, when compounded by environmental conditions, overwhelms the cooling mechanisms built into modern phones. As a result, protective measures are automatically triggered, screen brightness dims, processors slow down, charging is temporarily halted, and in extreme cases, the device powers off entirely to prevent damage. One of the most frequent mistakes users make is leaving their phones inside parked cars. Internal car temperatures can soar above 60 degrees Celsius under direct sunlight within minutes, creating conditions that can irreparably harm the battery, screen, and internal components. Experts recommend always taking the phone with them or ensuring it is shielded from direct sunlight if left in a vehicle. To mitigate overheating, users should avoid charging their phones in hot environments or under direct sunlight. Charging adds extra heat, increasing the risk of thermal stress on the device. If the phone feels excessively warm, users are advised to wait several minutes before connecting it to a charger. Removing thick silicone or rubber cases can also help dissipate heat more efficiently, as these materials tend to trap warmth rather than allow it to escape. When overheating warnings appear on the screen, immediate action is necessary. Users should stop using the phone, move it to a shaded area or air-conditioned space, disconnect the charger, and allow it to cool naturally. Most devices require only a few minutes of rest to resume normal operation. However, experts caution against placing the phone in refrigerators or freezers, a practice often promoted on social media platforms like TikTok. Rapid temperature drops can cause condensation inside the device, leading to long-term damage to sensitive electronics. Additionally, users should avoid using ice packs or cold covers on their phones, as sudden exposure to cold can create similar risks. If a phone frequently overheats even when not subjected to extreme conditions, there may be underlying hardware or software issues. Background applications might be overloading the processor, or the battery could have degraded over time. In such cases, checking app usage, updating the operating system, or visiting a service center for a battery replacement may be necessary. Manufacturers continue to refine cooling technologies and thermal management systems in newer models, but user behavior plays a crucial role in preventing overheating incidents. As mobile technology advances, maintaining proper device care becomes essential to ensure both performance and durability. The growing awareness around this issue suggests that future guidelines will likely emphasize proactive measures to protect smartphones from excessive heat.
