The Quick Checks: Simple Fixes for When Your Phone Won’t Charge
Before you assume the worst, let’s cover the basics. More often than not, the answer to “why wont my phone charge?” lies in a faulty accessory or a simple oversight. These initial steps take only a few moments and can save you a lot of time and worry.
1. Verify Your Power Source
It may sound obvious, but the problem might not be your phone or charger at all. It could be the power source itself.
- Wall Outlet: Unplug your charger and plug another device, like a lamp, into the same outlet. If it doesn’t work, the outlet is likely the issue. Try a different outlet in your home.
- Power Strip/Surge Protector: If you’re using a power strip, its internal fuse may have blown. Plug your charger directly into a wall outlet to see if this resolves the problem. Also, check if the power strip has a reset switch.
- Computer USB Port: Charging from a laptop or computer’s USB port is significantly slower and less powerful than a wall adapter. If your mobile phone not charging from a computer, try a dedicated wall outlet. Some older USB ports don’t provide enough power to charge modern smartphones, especially while they are in use.
2. Why Is My Phone Not Charging? Inspect Your Cable
The charging cable is the most common point of failure. These accessories endure daily twisting, bending, and pulling, which can lead to internal damage that isn’t always visible from the outside.
- Look for Physical Damage: Carefully inspect the entire length of the cable. Look for frays, kinks, bent connectors, or exposed wires, especially near the ends where the cable connects to your phone and the charging brick. If you see any visible damage, stop using the cable immediately and replace it. A damaged cable is not only unreliable but also a potential fire hazard.
- Test with a Different Cable: The easiest way to rule out a faulty cable is to try a different one. Grab a cable that you know is working (perhaps one from another device or a family member) and see if your phone starts charging. If it does, you’ve found your culprit. It’s always a good idea to invest in high-quality, certified cables from reputable brands like Anker or even the original manufacturer. These are built to last and are less likely to fail.
3. Try a Different Charging Brick (The Wall Adapter)
Just like the cable, the charging brick (the part that plugs into the wall) can also fail. It contains complex circuitry that can burn out over time or from a power surge.
- Swap the Brick: Keep the same cable you were using and connect it to a different charging brick. If your phone begins to charge, the original adapter is the problem.
- Check for Overheating: A faulty adapter can sometimes get excessively hot. While it’s normal for chargers to feel warm, if it’s too hot to touch comfortably, it’s a sign that it’s malfunctioning and should be replaced.
4. The Universal Fix: Reboot Your Device
If the accessories and power source are all working correctly, the issue could be a temporary software glitch. A simple restart can often clear up minor software conflicts that might be preventing your phone from recognizing that it’s connected to a power source. It’s a classic tech support tip for a reason—it works surprisingly often.
- For Android: Press and hold the power button until the power menu appears, then tap ‘Restart’.
- For iPhone (X or later): Press and hold the side button and one of the volume buttons simultaneously until the slider appears. Drag the slider to power off, wait 30 seconds, then press and hold the side button again to turn it back on.
- For iPhone (SE, 8, or earlier): Press and hold the top or side button until the power-off slider appears.
Once your phone has rebooted, plug it back in. This simple step can resolve the issue of why is my phone not charging even when plugged in.
The Charging Port – Your Phone’s Most Vulnerable Point
If the basic checks didn’t work, it’s time to investigate the most likely hardware culprit: the charging port itself. This tiny opening is constantly exposed to the elements and is a magnet for dust, pocket lint, and other debris. Over time, this buildup can become so compacted that it prevents the charging cable from making a solid connection.
The Answer to “Why Isn’t My Phone Charging?” Could Be a Dirty Port
Think about it: your phone goes in your pocket, your bag, and sits on various surfaces all day. Tiny particles of lint, dust, and dirt can easily find their way into the charging port. When you plug in your cable, you might be unknowingly pushing this debris deeper, packing it against the charging contacts at the back of the port.
Eventually, this layer of grime can become thick enough to physically block the charging cable from seating properly. You might notice the cable feels a bit loose or doesn’t “click” into place like it used to. This is a tell-tale sign that the port needs a good cleaning.
How to Safely Clean Your Phone’s Charging Port
Cleaning the port is a delicate process. The charging pins inside are fragile, and damaging them can lead to a permanent issue that requires professional repair. Proceed with caution.
What You’ll Need:
- A can of compressed air.
- A thin, non-conductive tool like a plastic or wooden toothpick. Never use a metal object like a paperclip or safety pin, as this can short-circuit the components and cause permanent damage.
- A bright light or flashlight.
Step-by-Step Cleaning Guide:
- Power Down: Turn your phone off completely to prevent any accidental short circuits.
- Visual Inspection: Use a flashlight to look inside the charging port. You might be surprised at how much lint and debris is packed in there.
- Use Compressed Air: Hold the can upright and use a few short bursts of air to dislodge and blow out any loose debris. Do not use your mouth to blow into the port, as this introduces moisture which can cause corrosion.
- Gently Scrape with a Toothpick: If compressed air isn’t enough, take your wooden or plastic toothpick. Very gently insert the tip and scrape along the inside walls of the port. Be careful to avoid the charging pins, which are usually on one side of the port. Use a gentle scooping motion to pull the debris out.
- Final Blast of Air: Give the port one last puff of compressed air to clear out anything you loosened.
- Power On and Test: Turn your phone back on and try charging it again. In many cases, you’ll find the problem is solved.
Checking for Corrosion or Physical Damage
While you’re inspecting the port, look for signs of corrosion (green or white residue) or bent/broken pins. Corrosion can happen if the phone has been exposed to moisture. If you see signs of corrosion or a pin looks damaged, this is likely the reason your mobile phone not charging. This type of damage usually requires professional repair, as the port itself will need to be replaced.
Part When Software is the Culprit
If your hardware and accessories all seem fine, the problem might lie within your phone’s software or operating system. Software is responsible for managing the charging process, and bugs or glitches can interfere with this critical function.
Why Your Phone Isn’t Charging: A Look at Software Glitches
Your phone’s operating system (OS) is a complex piece of software that controls every aspect of the device, including how it communicates with charging accessories. Sometimes, an error in the OS can prevent it from recognizing a power source, even when one is properly connected. This can often happen after a software update or if a particular system process crashes in the background.
Update Your Phone’s Software
Running an outdated version of your phone’s OS can cause a variety of issues, including charging problems. Manufacturers frequently release updates that include bug fixes for these types of glitches.
- For Android: Go to
Settings>System>System update(orSoftware update). - For iPhone: Go to
Settings>General>Software Update.
If an update is available, download and install it. Make sure your phone has enough battery (at least 50%) before starting the update process, or better yet, see if it will charge while you navigate to the update screen. Sometimes, just being on that screen is enough for it to recognize the charger.
Boot into Safe Mode to Diagnose the Issue
Third-party apps can sometimes interfere with your phone’s normal operation. Booting your phone into Safe Mode temporarily disables all downloaded apps, allowing you to determine if one of them is causing the charging problem.
- How to Enter Safe Mode on Android: The process can vary slightly by manufacturer, but it generally involves pressing and holding the power button, then long-pressing the ‘Power off’ option on the screen until you see a prompt to ‘Reboot to safe mode’.
- How to Check on iPhone: iPhones do not have a user-accessible “Safe Mode” equivalent to Android’s. The closest alternative is to see if the phone charges after a hard reset, which can clear out temporary app-related glitches.
Once in Safe Mode, try plugging your phone in. If it starts charging, then a recently installed app is almost certainly the culprit. You can then restart your phone normally and begin uninstalling your most recently added apps one by one until the problem is resolved.
This troubleshooting journey is a systematic process of elimination. Each step, from checking your cables to rebooting your phone, helps you narrow down the potential causes for why your device isn’t charging.
It’s important to remember that a phone is a sophisticated piece of technology where hardware and software are deeply intertwined. A charging problem isn’t just about the physical connection; it’s also about the complex digital “handshake” that occurs between the charger, the cable, and your phone’s internal system. A glitch in any part of this chain can bring the entire process to a halt.
For example, a firmware bug could prevent the phone from correctly identifying a charger’s voltage. In other cases, a background app could get stuck in a high-power state, consuming energy faster than it can be supplied. This creates the illusion that the phone isn’t charging at all.
By patiently working through these diagnostic steps, you are effectively acting as your own technician—methodically ruling out each possibility until you land on the solution.
Check for Apps Draining the Battery
In some rare cases, a rogue app can drain your battery so quickly that it outpaces the charging speed, making it seem like your phone isn’t charging. Check your battery usage statistics to see if any app is consuming an unusually high amount of power.
- Go to
Settings>Battery>Battery usage. Look for any app that has a disproportionately high percentage. If you find one, try uninstalling it to see if your charging issues resolve.
Investigating the Battery Itself
If you’ve ruled out the accessories, the port, and software, it’s time to consider the battery. All rechargeable batteries have a finite lifespan, and after a few years of use, they begin to degrade and lose their ability to hold a charge.
When the Problem is a Failing Battery, a Mobile Phone Not Charging is a Key Symptom
A phone battery typically lasts for about 500 full charge cycles, which for most people is about two to three years. As it ages, its maximum capacity decreases. Eventually, it may degrade to a point where it can no longer accept a charge at all.
Signs of a Failing Battery:
- The phone dies very quickly, even after a full charge.
- The phone shuts down unexpectedly, even with battery percentage showing.
- The battery percentage jumps around sporadically.
- The back of the phone feels unusually hot while charging.
- Physical swelling: If the back of your phone is bulging or the screen is being pushed out, this is a sign of a swollen battery. This is a serious hazard, and you should stop using the phone immediately and take it to a professional for safe removal and replacement.
How to Check Your Battery Health
Modern smartphones have built-in tools to help you check the health of your battery.
- For iPhone: Go to
Settings>Battery>Battery Health & Charging. You will see a “Maximum Capacity” percentage. If this number is below 80%, Apple considers the battery degraded and recommends service. - For Android: Android has a less direct built-in feature. You can often find some information in
Settings>Battery. For a more detailed analysis, you can download a third-party app like AccuBattery, which provides in-depth health statistics over time. You can find more information about how these apps work from reliable sources like PCMag.
If your battery health is poor, the only solution is to have it replaced by a qualified technician.
Advanced Issues and When to See a Pro
If you’ve reached this point and are still asking “why wont my phone charge?“, the problem is likely a more serious hardware failure that you can’t fix yourself.
Identifying Serious Hardware Failure
Several internal components can fail and lead to charging issues:
- Damaged Charging Port: As mentioned, if the port itself is physically damaged or corroded, it will need to be replaced.
- Water Damage: Even a small amount of moisture can cause short circuits and corrosion on the phone’s internal logic board. Most phones have a Liquid Damage Indicator (LDI) inside the SIM card slot—a small white sticker that turns red or pink when exposed to moisture. You can check your manufacturer’s website, like Apple’s support page, for its location.
- Faulty Charging IC or Motherboard: The charging process is managed by a specific microchip (the Tristar/Hydra chip on iPhones or the charging IC on Androids). If this chip fails, the phone won’t charge no matter what you do. This requires advanced micro-soldering to repair and is a job for a specialist.
When It’s Time to Seek Professional Help
If you suspect any of the above hardware issues, it’s time to stop troubleshooting and contact a professional.
- Manufacturer Support: If your phone is still under warranty, your first stop should be the manufacturer (Apple, Samsung, Google, etc.). They will be able to diagnose and repair the issue, often for free.
- Reputable Third-Party Repair Shops: For out-of-warranty repairs, a trusted local repair shop can often be a faster and more affordable option. Look for shops with good reviews that specialize in board-level repairs if you suspect a major hardware failure.
Conclusion: Solving the Charging Puzzle
Dealing with a phone that won’t charge is incredibly stressful, but as we’ve seen, the solution is often within your reach. By methodically working through these troubleshooting steps, you can systematically eliminate potential causes and pinpoint the exact reason why your phone is not charging.
Always start with the simplest solutions: check your power source, test your cable and adapter, and give your phone a quick restart. More often than not, the problem lies there. If not, a careful cleaning of the charging port is the next logical step and a very common fix. Only after exhausting these options should you begin to explore software issues or potential battery failure.
Remember to be patient and careful, especially when cleaning the delicate charging port. By following this guide, you are well-equipped to tackle this common problem head-on and, hopefully, bring your phone back to life without a costly trip to the repair shop.
