FIXING COMMON ISSUES ON IPHONE 6S AND IPHONE 6S PLUS

Sudden Power Off

If you're using iPhone 6s and the device suddenly powers off, despite no physical impact or dropping, the cause might be the iOS 9 version from Apple, which still has many bugs and deficiencies, leading to such situations.

To address the issue of iPhone self-shutdown, navigate to Settings > General > Reset > Reset all settings.

iPhone Overheating

Even with brief usage, your iPhone has become excessively hot. Prolonged overheating is detrimental, significantly reducing the device's lifespan.

The cause of iPhone overheating can be hardware or software-related. Alternatively, leaving background-running apps unchecked can lead to substantial battery consumption.

To check which apps consume a significant amount of battery, go to: Settings > Battery. If any app consumes over 30% of the battery without usage, it means the app is running in the background, and you may have forgotten to turn it off. Remember to disable or uninstall such apps.

Additionally, you can consider resetting your device by navigating to Settings > General > Reset > Reset all settings, similar to the ones mentioned above.

Low Battery Life

Despite being acclaimed as the most iconic smartphone currently, the iPhone 6s falls short in providing a high-capacity battery to users.

Similarly, check which apps consume the most battery and disable or remove them if unnecessary.
If you have enabled the background app refresh feature, promptly disable it. This is also the reason why your phone runs out of battery quickly despite not using it for long.

To turn off background app refresh, go to Settings > General > Background App Refresh, and then slide the switch to Off.

Similar to the tips on saving battery on iOS 9 to optimize your device's battery, you can go to Settings > Battery > Low Power Mode and activate this mode to extend battery life.

However, activating Low Power Mode will reduce network access speed, decrease device performance, and disable some features, so consider it carefully before proceeding.

3D Touch Malfunction

Regarded as a cutting-edge feature integrated into the iPhone 6s, 3D Touch sometimes malfunctions and becomes unusable. Hardware issues may be the cause of this situation.

To troubleshoot and adjust 3D Touch sensitivity, activate it through: Settings > General > Accessibility > 3D Touch, and enable it again.
