You probably already know that every iPhone model has had some problems if you’re wanting to acquire second hand iPhones in large quantities. It’s critical to be aware of any potential problems before buying these gadgets from a used iPhone wholesaler. Many of the typical issues with iPhones can be resolved for relatively little money. Here is a list in the iPhone repair shop blog, of frequent iPhone issues to look out for when purchasing old phones.
- Faulty batteries
When purchasing a used iPhone, the batteries should be checked first. Like other lithium batteries, iPhone batteries degrade over time. The likelihood of the battery failing on an iPhone increases with age. Battery capacity on used iPhones is typically lower than on new ones. However, certain older iPhones can experience issues with quick battery drain, when the battery drops from 80% to 20% in a short period of time, particularly after some iOS updates. Apple revealed that older battery-powered iPhones will operate more slowly. The real kicker is that further upgrades solve certain well-known software-related battery-drain issues. Additionally, Apple has introduced monitoring of battery capacity. Sometimes, a phone’s iOS can be upgraded to resolve battery problems.
- Face ID and Touch ID Issues
The Touch ID security feature on second hand iPhones might occasionally malfunction. These problems are frequently transient and can be resolved with software updates. But this is not always effective, just like with battery problems. Restoring the system settings to default is a good idea if you buy iPhones in bulk and some of the units have Touch ID problems. Restarting the iPhone and making sure the Touch ID feature is turned on are other options. If it doesn’t work, try updating iOS to the most recent version and scanning a fingerprint again. It frequently fails in failure scenarios where it ceases to function following an iOS upgrade. Attempt a device reboot. Enter Settings and reset Face ID if it doesn’t work.
- Touch Disease
The iPhone screen issue known as Touch Disease is distinct. The touch controller chip’s partial connection to the logic board causes this problem. A gray bar that flickers at the top of the display is the first sign of the problem. The phone’s touch screen becomes unresponsive as the chip continues to dislodge. The most frequent flaw in the iPhone 6 and 6+ was this one. Later iPhone versions include it as well. Touch Disease might be cured by a straightforward force restart. Alternatively, you can remove and replace your iPhone’s SIM card, reset the device’s factory settings, or erase resource-intensive apps from your iPhone. You can microsolder the touch screen controller chip back onto the logic board if none of these other options are successful.
- No Vibrations
The absence of vibrations on an iPhone may be among the most frequent issues. Your iPhone smartphone is malfunctioning if it doesn’t vibrate. Your iPhone’s vibration motor might need to be changed in order to resolve the problem. Thankfully, changing the vibration motor in a secondhand iPhone is not too difficult. After an iOS upgrade, a device may occasionally stop vibrating or giving haptic feedback. However, a software flaw isn’t necessarily to blame for the situation. When performing a DFU restore or going back to factory settings doesn’t resolve the issue, there’s a good probability that the haptic engine is broken and needs to be replaced.
- Cracked Glass
Regardless of whether it has a case and screen protector, an iPhone is a robust, durable device. Accidents do, however, occur. A fallen or tipped iPhone may have a cracked screen. The most typical iPhone problem is cracked glass. Replacing the entire screen is the only method to solve this problem. A cracked iPhone screen can be repaired using kits that are available online. They frequently come with guidelines you can use to securely remove and replace an iPhone screen that has broken.
- Screen glitches
Resetting usually works to fix the mysterious white screen of death. In the event that that doesn’t work, you may have to choose between a soft (factory) reset and a boot into DFU (Device Firmware Upgrade) mode. If you haven’t already, please take this as a friendly reminder to backup your data because doing so clears the data from your iPhone.
