1. Rapid Battery Drain
iPhones utilize lithium-ion batteries, which inevitably degrade over time. Improper charging habits can significantly reduce the battery's lifespan.
After approximately two years of usage (around 500 charging cycles), an iPhone's battery capacity may drop to only 80%. This means that what used to last for 10 hours after a full charge may now last only 8 hours.
If your iPhone exhibits signs of a weak battery that dies quickly, consider replacing the battery or upgrading to a newer smartphone.
You can assess your iPhone's battery health by navigating to Settings > Battery > Battery Health.
2. Sudden Reboot
An iPhone rebooting without apparent cause is a sign that your device may be experiencing issues.
Typically, iPhones reboot due to extreme temperatures, either too cold or too hot. In the case of cold temperatures, the iPhone will typically resume normal operation once the battery warms up. However, severe overheating can lead to damage to various components, including the battery. Other reasons for unexpected reboots could be internal malfunctions or software issues.
If your iPhone frequently shuts down and temperature is not the cause, it's advisable to promptly check your device.
3. Touchscreen Disorder
Touchscreen disorder manifests when the screen behaves erratically without any user input, such as apps opening or the screen jumping. This could be indicative of abnormal software behavior or screen damage due to water exposure or other internal issues.
If you notice this, especially if it's worsening, take your iPhone for inspection. You may need to replace parts, which can be as costly as buying a new iPhone.
4. Red Marks Near SIM Slot
This indicates that your iPhone has been exposed to water. If liquid gets inside your iPhone, it can void the warranty and lead to expensive repairs.
When you take your iPhone for repair, Apple typically checks the LCI (Liquid Contact Indicator). The LCI is usually white or silver but will turn red if it comes into contact with water.
You can check the LCI at home following Apple's instructions here.
Note that LCI doesn't typically turn red due to changes in humidity or weather. Most newer iPhone models are advertised as water-resistant, but you should still exercise caution.
5. iOS Update Issue
Apple regularly introduces new versions of iPhone software. These updates patch security vulnerabilities to fix serious issues with your device. So, if you're unable to receive those updates, you could be at risk of exploitation by malicious actors.
The latest release from Apple, iOS 15.4, currently supports all phones from the iPhone 6S and the first-generation iPhone SE.
Check if you're still receiving the latest updates in Settings > General > Software Update.
6. Dot on Camera and Microphone
This isn't a worrying sign of damage; it's related to a security issue.
When an orange dot appears in the top right corner of the screen, it means an app is using your iPhone's microphone. Whereas, if it's green, that app is accessing data from the camera.
Therefore, if you're concerned about privacy, you should check the app's permissions in Settings or completely delete the app.
Here are summarized 6 warning signs indicating that your iPhone may be malfunctioning and needs immediate inspection and repair. Hopefully, these insights will assist you in your usage journey.
