Why does my phone say it's charging but it's not? Complete guide and definitive solutions

One of the most frustrating problems for Android phone users is when their phone indicates it's charging, but the battery doesn't actually increase or even remains discharged. This scenario can cause anxiety, loss of connectivity, and difficulties in daily management. There are various causes, from hardware failures, dirty ports, charger or cable issues, to software errors and apps consuming power in the background. In this guide, we offer a complete explanation and step-by-step solutions to detect the real source of the problem and resolve it as quickly, safely, and effectively as possible, incorporating practical expert advice to get your phone charging properly again.

Common causes: Why does your phone indicate that it's charging but the battery doesn't go up?

The first essential step in troubleshooting any charging problem is correctly identify the causeThere are several main factors that can cause your phone to show that it's charging without the battery percentage actually increasing:

• Failure or deterioration of the cable or charger: Over time, improper cable wrapping, or constant pulling can cause internal damage, intermittent contacts, or even short circuits.
• Charging port clogged or damaged: Dust, lint, debris, or even a small deformation can prevent proper contact between the port and the cable.
• Battery wear or defect: Batteries degrade with charge/discharge cycles and can lose significant capacity or even swell.
• Background applications or processes: Some apps, services, and features may consume more power than they input, causing the battery to not charge.
• Operating system updates or errors: : Bugs after an update or corrupted files can interfere with the loading process.
• Recent contact with water or moisture: If your phone gets wet, it may block charging for safety reasons or affect the internal contacts.
• Internal hardware problems: Damage to the charging circuit, motherboard, microcontrollers, or internal connectors may prevent effective charging.

Correctly identifying the root of the problem is key to applying the right solution and avoiding further damage.

First checks before applying advanced solutions

Before taking your phone to a repair shop or performing hardware changes, perform these basic checks that cover the most common causes and can easily resolve the problem:

1. Change the cable and charger: Use another cable and adapter, preferably original and certified by the brand, to rule out accessory failures.
2. Try different power outlets: Sometimes the problem is in the plug or power strip, so check several electrical points.
3. Inspect the charging portUse a flashlight to check for dirt, lint, or debris that might be preventing contact. If there is dirt, clean the port properly (see below).
4. Reboot the device: A simple reboot can fix occasional software errors or blocked processes.
5. Look at the loading icon: Check if the lightning bolt or charging symbol appears on the screen and if the battery percentage increases after a few minutes.
6. Try wireless charging, if your phone supports it.: If your phone charges wirelessly but not with a cable, the problem is with the physical port.

If after performing these checks, your phone continues to show that it's charging but the battery doesn't increase, it's crucial to move forward with more specific solutions and a more in-depth review.

Detailed solutions for cable and charger problems

One of the most common causes behind charging failures is the deterioration or incompatibility of the USB cable or chargerHere are structured steps to rule out this problem:

• Visually examine the cableCheck for kinks, cracks, frayed areas, or loose ends. A cable with visible damage could be the culprit.
• Test the charger: Make sure the adapter is compatible and doesn't experience excessive heat or unusual noises. If it smells strange, replace it immediately.
• Check the charger powerAlways choose official chargers or those with the manufacturer's recommended specifications. A low-power charger may charge very slowly or not at all.
• Cross-match: Use your charger and cable with another device, and test your phone with different accessories to rule out whether the problem is with the accessories or the phone.
• Avoid generic or low-quality chargers and cables: : In the long run, they can cause damage to the charging port or the battery.

Replacing it with a new, original, certified accessory is usually sufficient to resolve most accessory-related charging faults.

Thorough cleaning and maintenance of the charging port

The charging port is one of the most sensitive areas and can accumulate dust, lint, dirt, or even suffer minor deformations., causing intermittent or no connections. To clean it properly, follow these recommendations:

1. Turn off the mobile and disconnect it from any power source to avoid short circuits.
2. Use a wooden toothpick, a soft brush (interdental type) or compressed air to carefully remove dust or debris from the port. Never use metal objects (such as pins or needles) as you could damage the internal contacts.
3. If dirt persistsUse compressed air in short bursts at an angle, or a cotton swab lightly moistened with isopropyl alcohol. Let it dry completely before reconnecting any accessories.
4. Check port alignmentIf you notice the connector moving after a drop or intensive use, consult a technician. Trying to straighten the port yourself may cause irreparable damage.
5. Attention to humidityIf your phone gets wet, let it dry for at least 24 hours in a well-ventilated area (you can use silica gel packs). Never use a hairdryer on a hot setting or leave it in direct sunlight.

La regular cleaning of the port Prevents most charging problems and can get seemingly unusable devices working again without costly repairs.

Battery Diagnostics and Care: How to Tell if Your Battery Is Failing

The battery is the component that suffers the most wear and tear with regular use., and malfunctions can manifest as no charge, excessively rapid discharge, swelling, or overheating. To check and respond promptly:

• Check the battery status from your phone's settings (on newer devices, go to Settings > Battery > Battery Health; on older models, use apps like Ampere.)
• Observe if the battery swells or heats up excessivelyA bulge is a sign of physical damage and requires immediate replacement.
• Check the charge cyclesBatteries lose efficiency after 500-1000 cycles, dropping their capacity below 80%. If this happens, charging errors can occur.
• Consider replacementIf it's removable, replace it with an original battery. If it's internal, consult a specialized service center. Do not attempt to open your phone without technical knowledge..

A defective battery can be dangerous and cause other damage. Act quickly if you notice any unusual symptoms.

Checking for software, applications, and settings that affect charging

Charging problems may be related to the software or applications that consume too much energy, affecting the battery percentage even if the phone indicates that it is charging:

1. Check Settings > Battery > Battery usage the consumption of each app, and remove or stop those that appear with atypically high consumption.
2. Update the operating system and applications: A bug or incorrect compatibility may be causing the charging to malfunction.
3. Disables non-essential functions while charging: Turn off Wi-Fi, Bluetooth and GPS to reduce power consumption and promote effective charging.
4. Close all open apps and background processes: Less activity, greater charging efficiency.
5. Charge your phone when it is turned off or in airplane mode.: If the battery life increases in this mode, the problem is caused by software or processes running in the background.
6. Perform a forced restart (hold down the power and volume down buttons for 10-15 seconds) to release blocked processes.

If charging issues occur after an update, consider restoring a previous version or performing a factory reset, making sure to back up your data first.
