There is perhaps no faster way to bring your iPhone to ruin than by exposing it to extreme temperatures and conditions on a consistent basis. The iPhone’s battery isn’t designed to withstand extreme cold OR heat, which means thinking twice about leaving your phone in the car when you dart out to the store to grab water isn’t a great idea, for more than just security issues. But although it may be obvious that direct sunlight is a mortal enemy to your smartphone, there are other, more subtle, lesser known ways that you could be helping your phone overheat. Here, Tech Expert Zeshan Malik takes a look at four dangerous ways that your iPhone can overheat that don’t involve the sun. The sooner you know, the quicker you can remedy your situation and protect your device.
High processor usage
Running resource-intensive apps or processes for an extended period can actually generate excessive heat. “For example, playing graphically demanding games or using augmented reality (AR) apps can put a significant strain on the processor,” Malik says. Malik’s prevention tips include closing unused apps running in the background, avoiding running multiple resource-intensive apps simultaneously, and taking regular breaks during extended usage sessions.
Software glitches or conflicts
“Certain software issues, such as bugs, conflicts, or faulty updates, can cause your iPhone’s processor to work excessively and result in overheating,” Malik says. To avoid this, it’s crucial that you keep your iPhone’s software up to date to benefit from bug fixes and improvements.
“Avoid installing unauthorized or suspicious apps that could potentially cause conflicts,” Malik adds — and restart your iPhone periodically to refresh the system.
Overcharging or using incompatible chargers
There is a such thing as too much of a good thing when it comes to charging your device. “Continuous charging or using third-party chargers that are not certified by Apple can lead to overheating issues, particularly if they are of low quality or incompatible with your device,” Malik says.
Use only Apple-certified charging accessories, avoid leaving your iPhone connected to the charger for prolonged periods once it's fully charged, and, if possible, remove the protective case while charging to promote better heat dissipation, Malik suggests.
Physical obstructions or covering
This one sounds so simple — but can have an enormous impact on your device: placing your iPhone on heat-trapping surfaces, covering it with thick cases, or using it inside tight pockets or bags can restrict airflow and lead to overheating.
“Use a lightweight and breathable case that allows proper airflow,” Malik suggests instead. “Avoid keeping your iPhone on heat-absorbing surfaces like blankets, cushions, or pillows. Keep your iPhone in a well-ventilated area while using it for extended periods.”
And remember: if you notice your iPhone getting excessively hot, it's essential to allow it to cool down before using it again to prevent any potential damage, Malik says. Overheating can happen, even on cloudy days, but it’s also avoidable.
