If your Mophie Juice Pack stops working, it can be frustrating. You rely on this portable battery case to keep your phone charged throughout the day. When it fails, your phone’s battery life can suddenly feel much shorter. Don’t worry—many issues with Mophie Juice Packs can be fixed with simple steps. This guide will help you understand why your Juice Pack may not be working and how to solve common problems. You’ll also discover useful troubleshooting tips, mistakes to avoid, and when it’s time to seek expert help.
Understanding The Mophie Juice Pack
The Mophie Juice Pack is a protective case with a built-in battery for smartphones. It’s popular among users who need extra power on the go. The case connects to your phone through a charging port and usually has LED indicators to show the battery level. Some models support wireless charging, while others use a micro-USB or USB-C port.
What makes the Juice Pack attractive is its ability to double your phone’s battery life without carrying a separate power bank. However, problems can arise due to wear and tear, compatibility issues, or incorrect use.
Common Reasons Your Mophie Juice Pack Isn’t Working
Several factors can cause your Juice Pack to stop charging or providing power. Let’s look at the most frequent reasons:
- Dirty or Damaged Connectors: Dust, lint, or corrosion can block the connection between the case and your phone.
- Battery Degradation: Rechargeable batteries lose capacity over time, reducing how much charge the case can hold.
- Incorrect Charging Cable or Adapter: Using a low-quality or incompatible cable can prevent charging.
- Firmware Issues: Some Juice Packs have chips that may need updating.
- Physical Damage: Drops or exposure to water can break internal components.
- Compatibility Problems: A Juice Pack designed for one phone model may not fit or work with another.
- Temperature Extremes: Very hot or cold environments can cause the battery to stop working temporarily.
Many users overlook the impact of dirty charging ports and cable quality. Even a small amount of dust can interrupt the flow of electricity, and not all cables work equally well.

Quick Troubleshooting Steps
Before you assume your Juice Pack is broken, try these steps:
- Clean the Connectors
- Gently brush the case’s connectors and your phone’s charging port with a dry, soft brush.
- Avoid using water or cleaning sprays.
- Check the Charging Cable and Adapter
- Use the original cable and adapter if possible.
- If you use a third-party cable, make sure it is certified and high-quality.
- Reset the Juice Pack
- For many models, press and hold the battery indicator button for 10–15 seconds to reset.
- Remove and Reattach the Case
- Carefully detach the Juice Pack and reattach it to ensure a solid connection.
- Charge the Case Separately
- Plug the Juice Pack into a wall charger without your phone attached. Wait until all LED lights turn on.
- Test with Another Device
- If you have access to a compatible phone, try using the Juice Pack with it. This can help identify if the issue is with the case or your phone.
Here’s a table comparing the effectiveness of different troubleshooting steps based on user reports:
| Step | Success Rate | Time Needed |
|---|---|---|
| Cleaning connectors | High | 2 min |
| Switching cables/adapters | Medium | 1 min |
| Resetting Juice Pack | Medium | 1 min |
| Testing with another phone | Low | 5 min |
Often, cleaning the connectors provides a quick fix. Users are sometimes surprised how much dust can build up in a phone case over time.
Signs Your Juice Pack Needs Replacement
If troubleshooting doesn’t fix your Juice Pack, it may be time to replace it. Here’s what to look for:
- No LED Lights: The indicator lights don’t turn on, even after charging.
- Case Feels Swollen: A swollen battery is dangerous—stop using it immediately.
- Short Charge Cycles: The case only charges your phone for a few minutes.
- Overheating: The case gets very hot during charging or use.
If you notice a bulging case or excessive heat, it’s important to stop using the Juice Pack. Damaged lithium batteries can be a safety hazard.

How To Choose The Right Replacement
When buying a new Juice Pack, consider these factors:
- Compatibility: Check that the model is made for your phone.
- Battery Capacity: Look for a pack with at least 80–100% of your phone’s battery size.
- Charging Speed: Some packs support fast charging.
- Warranty: A good warranty protects you from manufacturing defects.
- Brand Reputation: Stick with trusted brands like Mophie.
Here’s a quick comparison of Juice Pack models for popular phones:
| Model | Battery Capacity (mAh) | Charging Type | Compatible Phones |
|---|---|---|---|
| Mophie Juice Pack Access | 2,000 | Wireless/Qi | iPhone X/XS/11 Pro |
| Mophie Juice Pack Air | 2,525 | Wired | iPhone 6/7/8/SE (2nd Gen) |
| Mophie Juice Pack Samsung | 2,950 | Wired | Galaxy S8/S9/S10 |
If you often use your phone for video or games, a higher-capacity pack is better. For light users, a smaller, lighter case may be enough.
Common Mistakes To Avoid
Many people unknowingly shorten their Juice Pack’s life or cause problems by:
- Using Non-Certified Cables: Cheap cables can damage the battery or fail to charge properly.
- Not Cleaning: Leaving lint or dust in the connectors can stop charging.
- Exposing to Heat or Cold: Leaving your phone and Juice Pack in a hot car can damage the battery.
- Ignoring Warning Signs: Swelling or strange smells mean you should stop using the case immediately.
- Stacking Cases: Using the Juice Pack with another thick case can block the connectors.
A non-obvious mistake is charging both the phone and the Juice Pack at the same time using two chargers. This can confuse the electronics and cause charging failures.

Alternatives To The Mophie Juice Pack
If your Juice Pack is beyond repair, you might consider other options. Some alternatives include:
- Standalone Power Banks: These offer higher capacity but need a cable.

Here’s a comparison of alternatives:
| Product Type | Average Capacity (mAh) | Portability | Price Range |
|---|---|---|---|

| Standard Power Bank | 5,000–20,000 | Medium | $20–$60 |

If portability is your top priority, the Juice Pack is still a strong choice. For longer trips, a power bank may be better.
