If you’re seeking to buy used iPhones in bulk, you’re probably already aware that each iPhone and iPhone Plus model has had its fair share of common issues and problems. When acquiring these devices from a used iPhone reseller, it’s critical to be aware of the potential hazards. Many of the most frequent problems can be resolved for very little money.
The Most Common Issues With iPhones
You can look all over for old iPhones that have been precisely rated and thoroughly examined. Despite your best efforts, you may still run into a variety of iPhone problems.
Here are the most common iPhone issues, along with solutions.
There Are No Vibrations
No vibrations may be toward the top of the list of iPhone 5 common issues. Your iPhone smartphone is not working properly if there are no vibrations. The vibration motor in your iPhone may need to be changed to fix the problem.
It’s relatively straightforward to replace the vibration motor in an old iPhone. After an iOS upgrade, a handset may stop vibrating or delivering haptic feedback. However, the issue isn’t always caused by a software flaw. If restoring factory settings or doing a DFU restore does not resolve the issue, the haptic engine is likely malfunctioning and must be replaced.
- What to Do If There Are No Vibrations
Verify that the switch next to Vibration is turned on in your iPhone’s Accessibility settings. Your device should vibrate if the switch is green.
It’s also possible that if the iPhone’s vibration pattern is set to None, it won’t vibrate. In this case, go to Settings and choose General, then Sounds & Haptics, and finally Ringtone. At this point, go to the top of the screen and select Vibration. Make sure that everything except None has a checkmark next to it.
Defective Batteries
Bad batteries are one of the most common iPhone 6 flaws. Long-term use of an iPhone causes the battery to degrade. As a result, the more frequently an iPhone is used, the more likely the device’s battery may fail.
The battery capacity of used iPhones is typically lower than that of new iPhones. However, some older iPhones may experience quick battery drain issues, such as when the battery drops from 80% to 20% in a short period of time, especially after specific iOS updates.

It’s also worth mentioning that Apple has stated that iPhones with older batteries will slow down. The good news is that some of the known battery depletion concerns are software-related and will be addressed in future versions. Apple has also included the ability to monitor battery capacity. In some circumstances, updating the iOS on a phone can resolve battery concerns.
- How to Repair Faulty Batteries
To begin, make sure the phone’s iOS is up to date. Replace the battery if this doesn’t work.
In most cases, replacing a damaged iPhone battery takes only a few minutes. And each time you do it, it gets easier. To get you started, here’s an instruction on iPhone battery replacement.
Issues with Touch ID
In rare circumstances, the Touch ID security function on used iPhones fails. Most of the time, these problems are very transitory and may be resolved by installing software updates. However, just like with battery problems, this does not always work.
Touch ID issues on the Apple iPhone 5S are rather widespread. Apple has improved the Touch ID sensor in newer iPhone models to resolve these difficulties.

- How to Resolve Touch ID Issues
If you acquire a lot of iPhones and some of them have Touch ID troubles, reset the system settings to default. You can also try rebooting your iPhone and confirming that Touch ID is enabled. If it doesn’t work, upgrade your iOS to the most recent version and rescan your fingerprint.
Keep in mind that Touch ID might be a touchy subject. To clean the Touch ID, use a microfiber cloth. This allows you to clean the reader of any dust or dirt that could cause it to malfunction.
A light touch of the Touch ID sensor will not trigger a response. When using a used iPhone to test Touch ID, make sure your entire finger is positioned against the reader. To see if the reader responds to your finger, keep it motionless for at least a few seconds.
The responsiveness of Touch ID can also be influenced by the cover or screen protector used on an iPhone. As a result, you should try Touch ID on an iPhone without a case or screen protector.
Touch Disease
Touch Disease is a one-of-a-kind iPhone screen issue. This problem occurs when the touch controller chip fails to fully connect to the logic board. A flashing gray bar emerges at the top of the display as the first symptom. The phone’s touch screen becomes unresponsive as the chip detaches further.
The most common flaw with the iPhone 6 and 6+ was this. Other iPhone models have it as well.
- How to Recover from Touch Disease
A simple force restart may be enough to fix Touch Disease. You can also remove and replace your iPhone’s SIM card, reset the device’s factory settings, or erase resource-intensive apps. If none of these options work, you can resolder the touch screen controller chip onto the logic board using a micro soldering iron. This necessitates dexterity and caution. If you make a mistake while micro soldering, the iPhone could be permanently damaged.
A Cracked Glass
With or without a case and screen protector, an iPhone is a tough, durable smartphone. Accidents can happen in any situation. The screen of an iPhone might crack if it is dropped or falls.


A typical iPhone problem is cracked glass. This problem can only be solved by replacing the complete screen.
- How to Repair a Cracked Glass
You can buy kits to replace a cracked iPhone screen on the internet. They frequently provide instructions for properly removing a damaged iPhone screen and replacing it with a new one. This video, for example, shows how to change the screen on an iPhone 7 Plus.
- How to Troubleshoot iPhone Issues
You don’t have to be an Apple specialist to figure out how to mend an iPhone. Here are some suggestions for troubleshooting common iPhone issues:
- Factory Reset: To fix software and hardware issues, perform a factory reset.
- Remove Debris: Keep an eye out for debris that can accumulate under your iPhone’s buttons. To clear junk from your device, use compressed air from a can.
- Update iOS: Make sure your iPhone’s operating system is up to current. An iOS update normally just takes a few minutes to download and can significantly improve the speed and performance of a smartphone.
- Examine the condition of your battery: To evaluate your device’s performance, use the battery health setting (accessible on iPhones running iOS 11.3 and later). Replace the battery if its performance has decreased significantly.
- Restart Your iPhone: Shut down and restart your iPhone. Rebooting the iPhone resets the software and restores it to a stable state.
These suggestions will not fix every Apple iPhone issue. However, they can assist you in resolving typical iPhone issues in a timely and cost-effective manner. You can also use them to keep an eye on the condition of your iPhones in order to prevent problems from arising.
