Your phone can show the charging symbol while the battery percentage sits still, creeps up slowly, or drops anyway. That usually points to the charger, cable, port, battery settings, temperature protection, a liquid warning, or a software problem. Start with the fast physical checks, then move into settings only if the phone still will not take power.
Start with the cable, charger, and outlet
Plug the phone into a wall outlet and seat the cable firmly at both ends. Check the connection between the charging cable, power adapter, and outlet, then unplug and reconnect everything once.
Look at the cable and adapter for visible damage. On iPhone, try a different USB cable or charger. On Pixel, test another cable or power adapter and confirm the outlet works with something else.
For Samsung Galaxy phones, use a Samsung 25W, 45W, or 60W charger, or a USB-C PD3.0 PPS USB-certified charger that meets Samsung's listed power requirements. If your Pixel shows Check charging accessory, switch to a compatible cable and charger, such as Google's 30 W USB-C adapter or another USB Power Delivery adapter rated 15 W or more.
If the phone still says charging but the percentage does not move, leave it connected to a known-good charger and outlet for 30 minutes on iPhone, at least 10 more minutes on Pixel after the first minute, or at least 1 hour on a deeply discharged Samsung phone. If that fails, check the charging port next.
Remove anything blocking the charging port
Use this fix when the cable feels loose, charging works only at a certain angle, or the phone reacts to the charger without gaining battery.
Unplug the phone and inspect the charging port. Remove visible debris from the port area, then reconnect the cable firmly.
Check the charger, USB cable, and phone for dust, foreign material, physical damage, liquid damage, corrosion, or bent pins. If anything looks damaged, switch to another cable or charger before testing again.
Restart the phone before chasing bigger fixes
A temporary software hang is the most common reason a phone detects power but does not charge normally.
On iPhone X, iPhone 11, iPhone 12, iPhone 13, or later, press and hold either volume button and the side button until the power-off slider appears. Drag the slider, wait 30 seconds, then hold the side button until the Apple logo appears.
On iPhone 6, iPhone 7, iPhone 8, or iPhone SE second or third generation, hold the side button until the power-off slider appears. On iPhone SE first generation, iPhone 5, or earlier, use the top button instead. Drag the slider, wait 30 seconds, then hold the same button until the Apple logo appears.
On Pixel and many Android phones, press and hold the Power button for 5 to 7 seconds. On Samsung Galaxy phones, press and hold the Side button and Volume Down until the Samsung logo appears.
Check battery limits and charging holds
Some phones pause charging on purpose, especially near 80 percent or when battery-health features are active.
On iPhone 15 or later, open Settings, Battery, Charging, then choose a charge limit up to 100 percent when you need a full charge.
On iPhone 14 or earlier, open Settings, Battery, Battery Health & Charging, then turn Optimized Battery Charging off when you need charging to continue right away.
If an Optimized Battery Charging notice appears on the iPhone Lock Screen, touch and hold the notification, then tap Charge Now.
On Pixel 6a and later, open Settings, Battery, Battery health, Charging optimization. Charging optimization has to be on before Limit to 80% can be selected, so when you need a full charge, switch to Adaptive Charging or turn Charging optimization off. On Pixel 3 and later, the phone can also cap charging at about 70 to 80 percent on its own under certain conditions; tap the Charge to full link under Battery in Settings when that hold appears.
On Samsung Galaxy, open Settings, Battery, then turn off Protect Battery or Battery Protection when the phone is stuck at 80 or 85 percent.
Cool down or warm up the phone
Read the Lock Screen message. If an iPhone says Charging On Hold, charging will resume when the device returns to a normal temperature.
Move a hot phone to a cooler place away from direct sunlight.
Move a very cold phone to a warmer place.
Lock the screen or put the phone to sleep while it recovers.
Tip: treat a temperature hold as a protective pause, not a failed charger.
Handle wet-port and accessory warnings safely
Liquid detection and accessory alerts can stop wired charging even when the phone recognizes the cable.
If your iPhone reports liquid in the connector, unplug the cable from the iPhone and unplug the other end from the adapter or accessory.
Tap the iPhone gently against your hand with the connector facing down, then leave it in a dry area with airflow.
After at least 30 minutes, try wired charging again. If the alert returns, let it dry for up to a day.
If the iPhone or accessory is wet and you have a wireless charger, dry the back of the iPhone and place it on a Qi-certified charger instead of using the cable.
If an iPhone says the accessory is unsupported, connect the device directly to the charger without adapters or extra equipment, restart the iPhone, and try a different USB cable or charger.
Fix wireless charging that starts then stops
Poor alignment is the most common reason wireless charging appears briefly and then fails to add power.
Place the phone in the center of the charging pad with no obstructions. Remove cases, skins, protectors, wired headphones, charging cables, PopSockets, magnetic attachments, and other accessories before testing again.
Use the AC adapter and USB cable that came with the wireless charger or the device. For Pixel phones, use the approved wireless charger for your Pixel model.
For Samsung foldables, close the phone and place the rear side facing down on the pad. Galaxy A series, XCover series, and Galaxy Tab series models are not compatible with wireless charging.
Update the phone software
Software updates can resolve charging behavior caused by the operating system after the charger, cable, port, and battery settings check out.
On iPhone, back up the device, plug it into power, connect to Wi-Fi, then open Settings, General, Software Update. If an update appears, tap Download and Install and follow the onscreen instructions.
On Android, open Settings, System, Software updates, then follow the onscreen instructions. On Samsung Galaxy, open Settings, then tap Software update or System updates, depending on the model. The action is labeled Download and install, Check for system updates, or Check for software updates, depending on your model and carrier.
If your phone is managed by work or school and update options are missing, blocked, or marked as managed, contact your organization administrator before trying updates, Safe mode, or a reset.
If updating does not fix it, use the repair options from your phone maker instead of repeatedly forcing the same charger to work.
Frequently Asked Questions
Why does my phone say charging but it's not gaining battery?
The usual causes are a weak or damaged cable, a loose connection, debris in the charging port, a battery limit such as 80 percent charging, temperature protection, a wet-port warning, or a software problem.
Why is my phone stuck at 80 or 85 percent while charging?
A battery protection feature is limiting the charge. On iPhone, check Charging or Battery Health & Charging. On Pixel, check Charging optimization. On Samsung Galaxy, turn off Protect Battery or Battery Protection when you need a full charge.
Can I charge my phone wirelessly if the charging port is wet?
On iPhone, do not use wired charging when liquid is detected. If the back of the iPhone is dry and the model supports wireless charging, place it on a Qi-certified wireless charger.
When should I get the phone repaired?
Get service when the phone still will not charge after using a known-good charger and outlet, cleaning away visible debris, restarting, checking battery limits, handling temperature or liquid alerts, and updating the software.
