A phone that will not charge does not automatically need a new battery. The fault may be as simple as a dead wall outlet, damaged cable, incompatible adapter, blocked charging port, misaligned wireless charger, temperature protection or a battery that is so empty the screen needs time to wake up. The safest way to find the cause is to test one part of the charging chain at a time.

Quick answer: Connect the phone directly to a known-working wall outlet with a compatible, undamaged cable and power adapter. Check every connection, remove the case if it obstructs the plug, and leave a deeply discharged phone connected for at least 30 minutes. If it still does not charge, restart it, inspect the port with a light, try another proven cable and adapter, and check for temperature, moisture or unsupported-accessory warnings. Stop immediately if you see swelling, smoke, melting, corrosion, exposed wires or unusual heat.

Do not keep testing damaged or wet charging equipment. Stop using and charging the phone if the battery is swollen, the screen or back is lifting, the connector is burned or melted, there is smoke, hissing, leaking or a chemical smell, or the phone or cable becomes dangerously hot. Do not insert metal tools into the charging port, puncture a battery or force a connector. Arrange service through the manufacturer or an authorized repair provider.

What Does “My Phone Is Not Charging” Actually Mean?

Charging problems can look similar while having different causes. Before changing settings or buying accessories, note exactly what happens when power is connected. The charging icon, warning message, sound, vibration and battery percentage are useful clues.

What you notice	Likely area to check	Best first action
No icon, sound or vibration	Outlet, adapter, cable, port, empty battery or display	Use a proven wall outlet, cable and adapter; wait 30 minutes.
Charging starts and stops when the cable moves	Loose connector, damaged cable or worn/blocked port	Stop moving the plug; inspect and test another cable.
Charging icon appears but the percentage falls	Weak charger, heavy phone use, heat or failing accessory	Lock the screen and use a compatible wall charger.
Phone stops at 80%, 85%, 90% or another level	Charge limit, optimized charging or temperature protection	Check Battery or Charging settings and any on-screen message.
Liquid, moisture, debris or unplug warning	Port or cable protection	Disconnect immediately and follow the phone's drying instructions.
Accessory unsupported, incompatible or slow	Cable/adapter compatibility, damage or connection	Connect directly with a certified compatible accessory.
Wireless charging works but cable charging does not	Cable, adapter or physical port	Test the wired components separately and inspect the port.
Cable charging works but wireless does not	Alignment, case, attachment, charger or phone support	Remove obstructions and center the phone on a compatible pad.

A black screen does not prove that the phone is not charging. A fully discharged battery may need several minutes before it can show a battery symbol. A failed or extremely dim display can also hide charging activity. Google recommends checking whether the phone can ring after it has been connected to a working charger; if it rings while the screen remains blank, the display may be the problem. Android charging and power troubleshooting

The First 10 Checks to Try

Look for danger signs. Do not continue if there is swelling, smoke, melting, corrosion, exposed wiring, liquid inside the port or extreme heat.
Use a wall outlet. Laptop, car and hub ports may provide less power than a suitable wall adapter.
Confirm the outlet works. Test it with another safe appliance or use a different known-working outlet.
Reconnect every plug. Check the cable at the phone, at the adapter and the adapter at the outlet.
Remove interference. Take off a case only if it prevents the connector from seating fully or interferes with wireless alignment.
Try a proven compatible cable. A cable may fail internally without obvious damage.
Try a proven compatible adapter. Test only one component at a time so you know what changed.
Leave the phone connected. Give a deeply discharged battery at least 30 minutes before deciding it is not charging.
Restart or force-restart the phone. Do this only after the phone has had time to charge and shows no physical danger.
Read the exact warning. Temperature, moisture, debris, unsupported-accessory and charge-limit messages require different responses.

Apple's official sequence includes checking the power source, restarting the iPhone, inspecting the cable and adapter, trying another wall outlet, removing port debris and allowing at least 30 minutes of charging. Google's Android guidance similarly recommends testing the outlet, adapter, cable and port, then trying another compatible charging set. Apple iPhone charging guidance · Google Android charging guidance

How to Test the Charger, Cable and Power Source

1. Start With a Wall Outlet

Connect the adapter directly to a known-working wall outlet. Remove hubs, docks, extension accessories and pass-through adapters while troubleshooting. A computer or car USB port may charge slowly, share power with other equipment or fail to provide the charging standard the phone expects.

2. Inspect Without Continuing to Use Damaged Parts

Look for a split cable jacket, exposed wire, bent plug, loose connector, cracked adapter, bent wall prong, scorching, discoloration, corrosion or melting. Stop using anything damaged. Electrical tape does not make a damaged charging cable safe.

3. Cross-Test One Component at a Time

Test the original adapter and a different proven cable.
Then test the original cable and a different proven adapter.
Test the suspected cable and adapter with another compatible device.
Use direct connections while testing; remove hubs and multiport accessories.

If a cable charges another device but not your phone, it is not automatically compatible with the phone's required charging method. Some cables are intended mainly for data or low-power accessories; others are damaged or poorly made. Our USB-C to USB-C Charger Cable Buying Guide explains current rating, connector quality and how to choose a replacement.

4. Use the Correct Charging Standard

USB-C describes the connector, not a guaranteed charging speed. Many modern phones use USB Power Delivery, while some Android phones also use Programmable Power Supply or a manufacturer-specific fast-charging system. A charger with enough total wattage may still charge slowly if it does not support the protocol the phone uses.

A higher-watt compatible charger does not simply force its full printed wattage into the phone. The phone and charger negotiate supported power, and the phone controls what it accepts. Read Can a Higher Watt Charger Damage Your Phone? for a detailed explanation.

The best troubleshooting charger is not necessarily the one with the largest number on the label. It is a safe, undamaged charger that supports the phone's required standard and is paired with a suitable cable.

How to Inspect a Phone Charging Port Safely

Pocket lint, dust, corrosion or a damaged internal contact can prevent the plug from seating fully. A common clue is that the connector feels loose, leaves a visible gap or works only when held at an angle. Do not keep bending or pressing it into position; that can worsen damage to the cable or port.

Disconnect the phone from power.
Turn the phone off if it can be powered down normally.
Use a flashlight to look into the port without inserting anything.
Check the cable connector for moisture, dirt, corrosion, bending or scorching.
Follow the cleaning instructions published for the exact phone model.
Seek professional help if debris is tightly packed or the port is damaged.

Do not scrape a charging port with a pin, needle, knife, safety pin or other metal tool. Do not pour cleaning liquid into the port, force in a cotton swab or paper towel, or use heat to dry it. Apple specifically warns against foreign objects, external heat and compressed air when a liquid-detection alert appears. Google tells Pixel users not to put anything into a wet or debris-affected USB-C port. Follow the manufacturer instructions for your model rather than a viral cleaning trick.

If the port looks burned, melted or corroded, stop charging and arrange inspection. Repeated heat concentrated at the port can indicate a damaged connector, cable or internal charging circuit. The port may also have lost some water resistance after impact, wear or repair; see Is Your Phone Still Water-Resistant? Warning Signs.

How to Fix an Android Phone That Will Not Charge

Android button combinations, battery menus and diagnostic tools vary across Google Pixel, Samsung Galaxy, Xiaomi, OnePlus, Motorola, OPPO and other brands. Use the official support page for the exact model when a step differs.

1. Give a Deeply Discharged Battery Time

Connect a known-working compatible charger to a wall outlet and wait. Google says a red light can mean the battery is fully discharged; a flashing red light can mean there is not yet enough power to turn on. Its general Android guidance recommends charging for at least 30 minutes before restarting in that situation. Battery symbols and indicator lights vary by manufacturer. Google: Fix an Android device that won't charge or turn on

2. Restart the Phone

If the phone still has power, restart it normally. Google says holding the power button for five to seven seconds usually restarts an Android phone, but the correct button combination varies. Do not repeatedly force-restart a phone that is physically damaged, swollen, wet or extremely hot.

3. Check for an Accessory Warning

A “Check charging accessory” or similar message can mean the cable or adapter is damaged or unsupported. Replace the charging set with a compatible, proven cable and adapter. Pixel phones may use USB Power Delivery and PPS requirements that differ by model; Google's current Pixel guidance recommends a compatible USB-C power adapter and notes that laptops can charge more slowly than a wall outlet. Google Pixel charging guide

4. Check Charging and Battery-Protection Settings

If the phone charges but stops early or does not fast-charge, open Settings and search for Charging, Fast charging, Adaptive Charging or Battery protection. These features do not normally prevent all charging, but they can reduce speed or stop at a selected level to protect the battery.

On supported Galaxy phones, Samsung currently places fast-charging and battery-protection options under Settings > Battery > Charging settings or Battery protection. Names and paths vary with the model and software. Samsung also notes that a PC or ordinary USB device may not provide fast charging. Samsung Galaxy charging guidance

5. Run Manufacturer Diagnostics

On supported Galaxy devices, Samsung Members can test Battery status, Cable charging and Wireless charging through its Support or Phone diagnostics area. Other brands provide device-care or support apps with similar checks. Treat the diagnostic as evidence, not a license to keep using visibly damaged equipment.

6. Test Whether the Screen Is the Real Problem

After the phone has spent time on a working charger, call it from another phone or use the manufacturer's device-finding service. If it rings, vibrates or appears online while the display remains black, charging may be working and the screen may need repair.

Do not factory-reset the phone as an early charging fix. A reset erases local data and cannot repair a cable, adapter, charging port, battery or charging circuit. Use it only when the manufacturer specifically recommends it after safer tests and after creating a backup. If a reset is eventually required, read our Android and iPhone Backup Guide first.

How to Fix an iPhone That Will Not Charge

1. Use Apple's Basic Charging Sequence

Connect the iPhone to a working wall outlet with a compatible cable and USB adapter.
Check the cable and adapter for breakage, bent prongs or other damage.
Confirm that all connections are firm and try a different outlet.
Inspect the charging port and follow Apple's instructions for any debris.
Let the iPhone charge for 30 minutes.
If necessary, force-restart it using the method for that model.
Let it charge for another 30 minutes.

Apple recommends service if the iPhone still will not power on or charge after this sequence. Apple: If your iPhone won't charge

2. Force-Restart the Correct Way

For iPhone 8, iPhone SE (2nd generation) and later models, press and quickly release Volume Up, press and quickly release Volume Down, then hold the side button until the Apple logo appears. Older iPhone models use different combinations; follow Apple's model-specific instructions rather than guessing.

3. Understand “Accessory Not Supported,” “Slow Charger” and “Incompatible Charger”

An unsupported-accessory alert can be caused by a dirty or damaged port, defective accessory or unsuitable USB charger. Apple recommends connecting directly, checking the port, restarting the iPhone, trying another cable or charger and updating iOS.

On current software, a Slow Charger message means a higher-output charger could improve speed; it does not automatically mean the phone or charger is faulty. With iOS 26, an Incompatible Charger message can appear in Settings > Battery when a charger is connected but not charging. For faster charging, Apple recommends USB-C Power Delivery with the suitable cable for the iPhone model. Apple iPhone charge-speed guidance

4. Check Charge Limit and Optimized Battery Charging

An iPhone that stops at 80% or another selected level may be working as designed. Optimized Battery Charging can delay charging beyond 80%, while iPhone 15 and later models can use a configurable Charge Limit. On current iOS versions, open Settings > Battery > Charging to review the active limit and available temporary override. Apple iPhone Charge Limit guide

5. Check Temperature Before Blaming the Charger

An iPhone can slow or pause wired, MagSafe and other wireless charging when it becomes too hot or cold. Charging resumes automatically after the battery returns to a safe temperature. Move the iPhone away from direct sun or extreme cold and let it return gradually to a suitable temperature. Apple thermally limited charging guidance

What to Do About Moisture, Liquid, Debris and Temperature Warnings

If the Phone Reports Liquid or Moisture

Disconnect the charging cable immediately.
Disconnect the other end from the power adapter.
Keep the phone and cable in a dry place with airflow.
Follow the exact waiting time and drying method shown by the manufacturer.
Reconnect only after the port, cable ends and accessory are dry.

Apple says an iPhone liquid-detection alert disables charging and accessories until the connector, cable ends and accessory are dry. It recommends gently tapping the iPhone against a hand with the connector facing down, then leaving it in a dry area with airflow. Apple says to try again after at least 30 minutes; complete drying can take up to 24 hours. It specifically says not to use external heat, compressed air, cotton swabs, paper towels or rice. Apple liquid-detection guidance

Google tells Pixel users to disconnect power, turn the phone off and let a wet USB-C port or cable dry at room temperature. It warns not to put anything into the port. If a “Liquid or debris” message remains for two hours or more, Google's guidance says to contact support. Google Pixel USB-C warning guidance

Do not override a liquid warning merely for convenience. Apple provides an emergency override on supported iPhones, but charging a wet connector can corrode pins and cause permanent damage. Use that option only for a genuine emergency after considering the risk. If the back of the phone is completely dry and the model supports it, a compatible wireless charger may be an alternative while the port dries.

If Charging Is Paused Because the Phone Is Hot or Cold

Disconnect the charger if the phone or connector is unusually hot, stop demanding apps and move the device to a moderate indoor environment. Do not use a freezer, refrigerator, ice, hair dryer, heater or other rapid temperature change. Charging protections normally resume automatically after the battery returns to an acceptable range.

If heat is the main symptom, follow the dedicated safety steps in Why Is My Phone Overheating?.

How to Fix Wireless Charging That Is Not Working

First confirm that the exact phone model supports wireless charging and that the charger uses a compatible standard. A pad can light up even when it is not delivering useful power to the phone.

Connect the wireless charger to its recommended power adapter and a working outlet.
Place the pad on a flat, stable surface.
Center the phone on the charging area; try both orientations on a stand if supported.
Remove thick, metal or incompatible cases, wallets, ring holders and magnetic attachments.
Remove cards, coins, keys and other foreign objects between the phone and charger.
Let an overheated phone cool and try again with the screen off.
Test another known-compatible wireless charger or use wired charging to isolate the fault.

Apple says Qi charging works best when the iPhone is centered and notes that thick, metal or battery cases can interfere. Google similarly recommends correct alignment and removing metallic or magnetic objects when Pixel wireless charging is slow. Apple wireless-charging guidance · Google Pixel wireless-charging guidance

Wireless charging may be slower and warmer than wired charging. Alignment, charger certification, case design and the adapter powering the pad all matter. See Wireless Charging Explained and our Qi2 25W Guide for the standards behind it.

Why Is the Phone Charging Slowly or Stopping Early?

Possible cause	Clue	What to do
Low-power source	Charging from a laptop, car, hub or old adapter	Use a compatible wall charger.
Protocol mismatch	Phone says slow or incompatible charger	Use the charging standard recommended for the model.
Damaged or low-rated cable	Intermittent charging or speed changes with another cable	Replace it with a safe compatible cable.
Heavy use	Gaming, camera, hotspot or navigation is active	Lock the screen and stop demanding tasks.
High or low temperature	Charging-on-hold or temperature message	Return the phone gradually to a suitable environment.
Charge limit	Charging stops at the same selected percentage	Review Battery or Charging settings.
Adaptive charging	Charging pauses overnight and finishes near wake time	Review the adaptive or optimized charging setting.
Background battery drain	Charging icon appears but percentage barely rises	Check battery usage, signal and active apps.
Worn battery or hardware fault	Rapid drain, shutdowns, swelling or repeated heat	Arrange authorized diagnostics and service.

Do not disable battery protection permanently just to prove the phone can reach 100%. A configured limit is not a fault. Temporarily change it only when you genuinely need a fuller charge and understand that reducing time at very high charge levels can help limit battery wear.

If the phone gains charge but loses it unusually quickly after unplugging, the problem may be battery drain rather than charging. Review the daily-care guidance in How to Extend Smartphone Battery Life.

When Should You Stop Troubleshooting and Get Repair?

Arrange professional inspection when:

The battery, screen or back cover is swollen or lifting.
The phone, port, cable or adapter is burned, melted or corroded.
There is smoke, hissing, leaking, scorching or a chemical smell.
The connector only works at an angle after testing another cable.
The charging port is loose, deformed or has damaged contacts.
Liquid or debris warnings return after the equipment is fully dry and clean.
The phone repeatedly becomes dangerously hot while charging.
A proven compatible charging set and outlet produce no response after sufficient time.
The phone charges wirelessly but every proven wired charger fails, or the reverse.
Charging remains abnormally slow after software, temperature, settings and accessories are ruled out.

A swollen battery needs special handling. Do not charge it, press the phone closed or puncture the battery. Read Swollen Phone Battery: Warning Signs and Safe Steps and contact the manufacturer or an authorized service provider.

Back up data only if the phone is cool, physically intact and safe to operate. Do not continue powering or charging a damaged phone merely to complete a backup. A repair provider may be able to advise whether safe data recovery is possible.

Phone-Charging Myths to Avoid

“Any USB-C charger is identical”

USB-C is a connector. Power rating, supported protocols, cable capability and safety certification still differ.

“A higher-watt charger forces too much power”

A compatible system negotiates power. Damage and incompatibility are different problems from the maximum number printed on the adapter.

“Scrape the port with a pin”

A metal tool can short or damage contacts. Inspect visually and follow the phone manufacturer's cleaning instructions.

“Rice dries a wet charging port”

Apple specifically warns that rice particles can damage an iPhone. Use dry airflow and the official waiting method.

“Stopping at 80% means the battery failed”

Temperature protection, optimized charging or a configured charge limit may be working as designed.

“A factory reset repairs charging hardware”

A reset cannot fix a broken cable, worn port, swollen battery or failed charging circuit.

A Practical Troubleshooting Order

Stop for safety: Rule out swelling, heat, smoke, liquid, melting and damaged wires.
Read the symptom: Note the icon, warning, battery level and whether wired or wireless charging works.
Prove the power source: Use a working wall outlet.
Prove the external parts: Cross-test the cable and adapter one at a time.
Inspect the connection: Check case interference, port debris, moisture and physical damage.
Allow recovery time: Leave a deeply discharged phone connected for at least 30 minutes.
Restart safely: Use the correct normal or forced restart for the model.
Check software protections: Review charge limits, optimized charging, fast-charging settings and temperature messages.
Test the alternate method: Try wired or wireless charging if the phone supports both.
Escalate: Arrange authorized service when the fault persists or any hardware warning appears.

Frequently Asked Questions

Why is my phone plugged in but not charging?

The outlet, adapter, cable or port may not be making a working connection. The phone may also have paused charging because of temperature, moisture, an incompatible accessory or a configured charging limit. Connect directly to a proven wall outlet with a compatible cable and adapter, then read any warning shown.

How long should a dead phone charge before turning on?

Allow at least 30 minutes when the battery may be deeply discharged. A battery symbol can take several minutes to appear. Google and Apple both include a 30-minute charging period in their official troubleshooting guidance. The exact time varies by model, charger, battery condition and temperature.

How can I tell whether the cable or charging port is broken?

Test a known-working compatible cable and adapter. If several proven cables fail only on that phone, the port becomes more likely. A loose fit, visible damage, corrosion, melting or charging only at an angle also points toward the port, but an authorized diagnostic is the safest confirmation.

Why does my phone charge only when the cable is held at an angle?

The cable connector may be worn, debris may prevent full insertion, or the phone's port may be loose or damaged. Stop bending the cable into position. Test another compatible cable and inspect the powered-off phone with a light. Seek service if the problem continues.

Can I clean a charging port with a toothpick?

Do not assume a toothpick or other object is safe for every phone. Port designs and manufacturer instructions differ, and broken material can become trapped. Never use metal. Start with visual inspection and follow the cleaning instructions for the exact model; use professional service for tightly packed debris.

Why does my phone stop charging at 80 percent?

The battery may be warm, Optimized or Adaptive Charging may be active, or a Charge Limit or Battery protection setting may be selected. Check the Battery or Charging screen and the exact message shown before changing anything.

Can a charger be too powerful for my phone?

A standards-compliant compatible charger can have a higher maximum wattage than the phone needs because the device negotiates and controls accepted power. Compatibility, supported charging protocol, cable capability, product quality and safety certification still matter.

Why is my phone charging slowly even with a fast charger?

The cable or adapter may not support the phone's fast-charging protocol, the phone may be hot or cold, a laptop or multiport charger may provide reduced power, or heavy apps may consume energy while charging. Battery protection can also reduce speed near the selected limit.

Can I charge a wet phone wirelessly?

Only consider wireless charging if the manufacturer allows it, the phone supports it and the entire back of the phone is dry. Do not place a wet device or wet charger on power. A wet wired port still needs to dry fully before cable charging or accessory use.

Why does the charging icon appear but the battery percentage goes down?

The phone may be consuming power faster than the source provides. Common causes include a weak adapter, unsuitable cable, computer USB port, gaming, camera use, navigation, hotspot use, high brightness, poor signal or heat. Lock the screen and test a compatible wall charger.

Should I replace the battery if the phone will not charge?

Not before testing the outlet, adapter, cable, port, temperature, moisture warnings and software protections. Replace or service a battery when authorized diagnostics indicate a fault or when there are symptoms such as swelling, rapid drain, repeated shutdowns or abnormal heat.

Will a factory reset fix a phone that does not charge?

Usually not. A reset cannot repair charging hardware and erases local data. Use it only if the manufacturer recommends it after hardware and accessory checks, and back up the phone first when it is safe to operate.

Final Thoughts

A charging failure is a chain problem until proven otherwise. The wall outlet, adapter, cable, connector, charging port, battery, temperature controls and software can each affect the result. Testing them in a safe order is faster and more reliable than buying random accessories or repeatedly forcing the plug.

Begin with a known-working wall outlet and compatible charging set, allow a deeply discharged battery enough time, then investigate the port, warnings and settings. Stop immediately when there is swelling, liquid, smoke, melting, corrosion or unusual heat. Persistent failure after the external parts are ruled out belongs with the manufacturer or an authorized repair provider.
