Battery percentage not increasing? You leave your phone charging overnight, only to wake up and find the battery percentage hasn’t budged. The charging icon and the lightning bolt indicator are visible, yet the percentage remains stuck exactly where it was the night before. This is a common issue faced by users of brands like Samsung, Redmi, Realme, OnePlus, and Vivo across India. Initially, you might suspect a faulty charger or try swapping the cable; when that fails, your first thought is often to head straight to a service center. But wait – more often than not, this problem can be fixed right at home; you just need to know the root cause.
When the battery percentage stays stuck despite the charging indicator being active, it means power is reaching the phone but isn’t being stored correctly in the battery cells. In this detailed guide, we will explain every possible cause – from software glitches to hardware faults – along with practical solutions, all in simple, easy-to-understand language.
Why isn’t the battery percentage increasing? Find out the real reasons.
There could be several reasons behind this issue. Sometimes the cause is something minor, like dust in the charging port, while at other times, the problem could lie with the battery or the motherboard. Let’s look at them one by one.
Reason 1: Faulty or counterfeit charging cables and adapters
This is the most common cause, especially in India, as many people buy cables for ₹50–100 from roadside shops.
People often use just any cable – such as a friend’s spare or one meant for a different gadget. However, low-quality or incompatible chargers often deliver inconsistent voltage. Your phone registers that it is charging because it is receiving power, but that power is neither sufficient nor stable enough to actually charge the battery.
Chargers can become loose over time. Damaged or loose cables transmit very little current. Charging cables get damaged from repeated bending. Wall adapters can also sustain damage due to high voltage or faults in the USB port.
How to check:
- Try charging with a different cable and adapter.
- Borrow an original cable from a friend. If the phone starts charging normally, the problem isn’t with your battery – it’s with your accessories.
- Always buy original or BIS-certified cables from your brand.
Reason 2: Dust, dirt, or lint in the charging port
This is the second most common reason, especially for those who carry their phones in their pockets without a case.
A dirty or clogged charging port is one of the most common reasons why a phone appears to be charging but the battery percentage does not increase. Over time, dust, lint, or small particles accumulate inside the port, preventing the charger from making proper contact with the battery terminals. This can happen even when the charging icon is visible on the screen.
How to clean it:
- Carefully inspect the port and remove any debris using a soft anti-static brush, a small wooden stick, or a new toothpick. Exercise caution – applying too much pressure could damage the delicate internal pins.
- Shine a flashlight into the port to check for dust or bent pins. If there is debris, gently clean it out with a dry, soft brush. Do not use any liquids.
- Never insert a metal needle or pin into the port.
Reason 3: Software Glitch or OS Bug
Sometimes, the phone’s battery is actually charging, but the system fails to update the percentage display.
At other times, the phone indicates it is charging even though the battery isn’t actually receiving power. This is usually caused by minor bugs in the operating system or firmware that confuse the device, leading to an incorrect battery level reading. Such issues can occur after a system update, following prolonged use without a restart, or when background apps interfere with normal operations. In most cases, restarting the phone, updating the software, or clearing temporary system errors can resolve the problem.
Reason 4: Battery calibration is out of order
This is a reason about which very few people know, but it is quite common in the complaint of battery percentage not increasing.
Sometimes your phone’s system loses track of the actual charge level. This can happen after an update, or when the phone is completely discharged and restarted.
Restart the phone and plug it in again. If that doesn’t work, drain the battery completely until the phone turns off, then charge it to 100% in one go. This “recalibrates” the battery readings and usually brings the percentage back to normal.
Reason 5: Running heavy apps while charging
Many people have a habit of playing games like BGMI or watching HD videos on YouTube while their phone is plugged in. This is a major mistake.
Using navigation, gaming, video calls, or a hotspot while charging can drain power just as fast as it is being replenished. In such cases, the phone is indeed charging – but not faster than the rate of power consumption.
Background apps and bloatware can consume more power than your charger provides. Low-wattage chargers (such as older USB ports) often cannot keep up with the power draw.
What to do:
- Close all active apps. Reduce screen brightness. Use the recommended high-wattage charger for your device. Charge the phone in a cool and well-ventilated area.
- It is better not to touch the phone while charging
Reason 6: The phone is overheating
This is a very common problem during Indian summers. Charging a phone in temperatures exceeding 40°C can even be dangerous.
A smartphone may fail to charge if it is overheating. This can happen after the phone has been exposed to direct sunlight or following a long gaming session. When the phone overheats, it automatically slows down charging to protect the battery from damage. If this happens, unplug the phone, remove the protective case, and close any background apps. Allow the device to cool down for a while before charging it again.
Tip: Never charge your phone on a pillow or quilt, as this traps heat.
Reason 7: The battery is old (reduced battery health)
Every battery has a lifespan. After about two years of daily use, most lithium-ion cells begin to degrade. The phone still turns on, but the battery can no longer hold a charge properly. This leads to erratic behavior: the percentage gets stuck, fluctuates suddenly, or drops sharply as soon as the phone is unplugged. When it reaches this stage, replacing the battery is the only real solution.
How to check:
- Check the battery health in your device settings (available on most Android phones and iPhones). If the capacity is below 80% or the device is shutting down unexpectedly, consider replacing the battery.
- iPhone: Settings > Battery > Battery Health & Charging
- Samsung: Settings > Battery and Device Care > Battery > Battery Information
- Xiaomi/Redmi: Settings > Battery > Battery Health
Reason 8: Faulty Charging IC or Motherboard
This is the most serious issue and requires professional assistance.
If none of the previous methods work, the problem might lie with the charging IC – a small chip that regulates the flow of current from the charging port to the battery. When it fails, the phone detects the charger but cannot store energy. This is not a DIY task; it requires diagnostic tools and micro-soldering skills.
The motherboard is the phone’s central circuit board that connects all components. When it begins to fail, power does not reach the battery correctly; consequently, the charging icon appears, but the battery percentage remains stuck. Overheating caused by heavy usage – such as long gaming sessions or continuous video streaming – can damage the tiny components on the board.
Now, let’s look at the solutions – what to do if the battery percentage isn’t increasing.
Fix 1: Restart the phone – The first step
This is the most basic yet most effective step.
The very first fix applicable to this issue – or any Android smartphone problem – is to reboot the device. Restarting clears any faulty apps or services from memory that might be interfering with charging. To restart the phone, press and hold the power button for 5–7 seconds, select “Power Off,” wait for a minute, and then turn it back on.
A Samsung Galaxy A14 user shared that their phone displayed the charging icon, but the battery percentage remained unchanged. It started working correctly after a restart.
Fix 2: Try a different cable, adapter, and power source
Low-quality or damaged chargers often supply power but fail to deliver sufficient current. This causes the battery level to get stuck or increase very slowly. Switching to certified chargers and cables resolves the issue in many cases.
Do this:
- Use an original or branded cable.
- Plug your charger into a different wall socket or laptop USB port. Sometimes, the issue is simply unstable power from your power strip.
- Charging via a laptop’s USB port will be very slow – use a wall charger instead.
Fix 3: Clean the charging port thoroughly
We mentioned the reason above; here is the detailed method:
- Turn off the phone.
- Use a flashlight to get a better view inside the port. If any debris is stuck inside, carefully clean it out using a SIM ejector tool or a toothpick. Just be careful not to damage the charging pins, as doing so could permanently damage the phone. After thoroughly cleaning the port, try charging the phone again.
- Never pour water or any liquid into the port.
Fix 4: Close background apps and turn on Low Power Mode
When the battery percentage isn’t increasing, the first thing to do is close all unnecessary apps running on your phone.
Closing background apps and performing a soft reset can help increase the battery percentage.
On Android:
- Settings > Battery > Turn on Battery Saver
- Clear all apps from Recent Apps
- Turn off Location, Bluetooth, and NFC if they are not needed
On iPhone:
- Turning on Low Power Mode allows the iPhone to charge faster and more efficiently. This mode reduces power consumption by processes such as background app refresh.
Fix 5: Check for software updates
Outdated software can cause battery and charging-related issues.
System updates often fix bugs that affect charging and battery recognition.
Android: Settings > System > Software Update > Check for Updates
iPhone: Settings > General > Software Update
Fix 6: Charge in Safe Mode
If a third-party app is interfering with charging, Safe Mode is the best way to identify it.
On most Android devices, to enter Safe Mode, tap and hold the Restart button while powering off. You will see a prompt to reboot into Safe Mode. To exit Safe Mode, simply restart your phone normally. If the phone charges in Safe Mode, it confirms that a third-party service is causing the issue. Once confirmed, check your recently downloaded apps; one of them could be the culprit. Uninstall the recently installed apps, then restart your phone normally and check if it charges.
Fix 7: Calibrate the battery
If the battery percentage is displaying incorrectly – such as suddenly dropping from 50% to 20%, or not increasing while charging – then calibration is necessary.
Manual calibration method:
- Use the phone until it shuts down on its own.
- Plug in the charger without turning the phone on.
- Charge the battery to 100% in one go.
- Leave the charger connected for another 30 minutes after reaching 100%.
- Now, turn on the phone.
This process resets the battery stats file, and the percentage returns to normal.
Fix 8: Check Battery Optimization / Protection Settings
Many new phones feature a “Battery Protection” setting that stops charging once the battery reaches 80%.
If your phone detects the charger but stops charging beyond a certain percentage, it is possible that the “Hold Charge” feature – designed to extend battery lifespan – is active. Look for the “Hold Charge” or “Battery Protection” setting in your battery options and turn it off.
Most modern smartphones include software features to protect the battery from overcharging and short circuits. One such feature is “Battery Optimization”; while it protects the battery, it can sometimes interfere with charging. If you suspect this is the issue, disable battery optimization and try charging again. Search for “battery optimization” or “charging optimization” in your phone’s settings to turn it off. After disabling it, plug in the charger and check if it works.
Where to find it by brand:
- Samsung: Settings > Battery > Charging Settings > Adaptive Charging (Turn off)
- OnePlus: Settings > Battery > Optimised Charging
- iPhone: Settings > Battery > Battery Health & Charging > Optimized Battery Charging
Fix 9: Test using wireless charging
If your phone supports wireless charging, this is a useful diagnostic step.
If your phone is equipped with wireless charging and you have a wireless charger, this is an easy way to determine if the issue lies with the phone’s port or accessories. Try charging it wirelessly. This can also serve as a temporary solution to keep the phone running while you resolve the problem. However, if it fails to charge even with a wireless charger, there could be a major issue with the battery.
Fix 10: Factory Reset – The Last Resort
If all the previous methods fail and you suspect a software issue, a factory reset is the final option.
If none of the earlier solutions work, performing a factory reset is the last step to take before visiting a service center. Resetting the phone to factory settings can resolve software issues, as well as fix faulty apps or services that might be blocking charging. However, this process will delete all your data and apps, so make sure to back up everything important before proceeding.
Settings > General Management > Reset > Factory Data Reset

Tips to keep the battery healthy for a long time
- Keep the charge between 20% and 80% – avoid letting the battery drop to 0% or charging it to 100% every time.
- Use the original charger – low-quality or unapproved chargers and cables can cause slow charging or intermittent disconnections. Use Samsung-approved chargers or certified accessories.
- Do not play games while charging – this places double the strain on the battery.
- Charging may be limited if the device or the surrounding environment is too hot or too cold. Charge at room temperature for stable charging.
- Do not leave the device charging overnight – keep Adaptive Charging enabled.
When is it necessary to visit a service center?
A phone that isn’t charging doesn’t always need to be replaced. Start with the basics – check the cable, clean the port, update the software, and verify the power source. Most issues can be resolved at home in minutes. If nothing works, have a technician check the port, battery, or circuitry.
Here are the signs that you should visit a service center:
- The battery has swollen (the phone’s back cover is lifting).
- The charging IC (Tristar/U2 chip) or battery connector might be damaged.
- No change even after trying multiple cables and chargers.
- The phone is overheating while charging.
FAQs – Battery percentage not increasing
Q1: The phone is charging, but the battery percentage isn’t increasing – what should I do first?
First, restart your phone, then try a different cable and charger. If it still isn’t charging, restart the device and use a different charging cable, adapter, and power outlet.
Q2: Can the Ampere app tell if charging is taking place?
Ampere is a simple app that shows the current flowing into or out of the phone (charging or discharging). It also displays battery condition, voltage, and temperature. Install the Ampere app, connect your phone to a power source, open the app, and check the readings. If the phone is charging but the icon doesn’t appear, it could be a software bug.
Q3: At what battery health level should the battery be replaced?
A phone’s battery loses capacity over time. When battery health drops below approximately 80%, charging slows down, and the percentage indicator may appear stuck. Replacing the battery is the best option at this stage.
Q4: Is it okay to leave the phone charging overnight?
Generally, charging overnight is safe, but keeping the phone at 100% charge for extended periods isn’t ideal. Enabling ‘Optimized Charging’ or ‘Adaptive Charging’ helps prevent this issue.
Q5: I’m getting a ‘Moisture Detection Warning’ – what should I do?
If your phone has recently come into contact with liquid, check for a ‘Moisture Detection Warning.’ This prevents the phone from charging until the port is completely dry. Place the phone in a cool, airy spot and wait for at least 2–3 hours.
Q6: The battery percentage isn’t increasing on my iPhone – is there anything different to consider?
iPhones have an ‘Optimized Battery Charging’ feature located under Settings > Battery > Battery Health & Charging; try turning it off. To extend battery lifespan, this feature sometimes delays the visible charging progress.
