What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If your phone, tablet, or laptop loses charge while connected to power, it is drawing energy faster than the charger is supplying it—or charging is being slowed or interrupted. That symptom alone does not prove the battery has failed. Check the charger, cable, connection, workload, temperature, and device settings before seeking service.
What a falling battery percentage means
A connected device can still lose stored energy when its power use exceeds incoming power. On Windows PCs, Microsoft identifies an incompatible or underpowered charger, an unsuitable cable, and connection problems as possible causes of discharging while plugged in. On phones, charging can slow or stop because of accessory faults, heat, moisture or debris in the port, or charging settings. The exact cause depends on the device and its setup.

Check the charger, cable, and connection
Reseat the connection at the wall, adapter, and device. Inspect the charger and cable for visible damage, and test with a known-good charger and cable specified for your model. Replace an accessory only if it is damaged, incompatible, or unable to supply the required power.

A USB-C plug does not, by itself, tell you whether the full charging chain can deliver enough power. For a laptop, check the manufacturer’s requirements for the computer, adapter, cable, and charging port. Microsoft gives 5V, 3A (15W) as an example of what USB-C can support, while USB Power Delivery can support higher power when the devices and cable support it. That 15W example is not a recommendation for every PC; some laptops need more.
When choosing a replacement, verify compatibility with the device model, supported charging standard, output power, cable capability, and connector fit. A higher-wattage charger is not a guaranteed fix for a damaged port, heat-related slowdown, a charging setting, or a battery fault. See Microsoft’s PC charging guidance and Samsung’s Galaxy charging troubleshooting steps.

Reduce power use while testing
Close demanding apps and avoid intensive tasks during a short charging test. On a PC, try charging while it is asleep or turned off; Microsoft recommends this as a way to charge faster. If the percentage rises under lighter use, power demand may be contributing, but that result does not identify a specific hardware fault or rule out other causes.

Check for heat, moisture, or a blocked port
If the device is hot
Stop the test and let the device cool in a normal environment. Avoid demanding use and other heat-trapping conditions while charging, and do not put the device in a refrigerator or freezer. Samsung notes that high temperature can temporarily stop charging or reduce its speed. Apple says iPhone charging current is reduced as the battery approaches full charge to limit heat; very cold conditions can also temporarily reduce battery life.

Apple describes 16° to 22°C (62° to 72°F) as the ideal ambient operating temperature range for iPhone. It advises avoiding charging in ambient temperatures above 35°C (95°F) because battery lifespan may be permanently reduced. These are Apple’s iPhone-specific temperature recommendations, published April 8, 2025—not universal limits for every device. See Apple’s iPhone battery guidance.
If the port is wet or obstructed
Do not charge through a wet port. A moisture warning may stop charging, and debris can prevent a proper connection. Follow the device maker’s cleaning instructions; do not use metal picks or liquids, force a connector into the port, or try to charge through persistent moisture alerts. If the port is damaged or an alert persists, seek the manufacturer’s service guidance. Samsung’s Galaxy charging tips cover moisture, port condition, and overheating.

Review charging settings on phones
Some phones have battery-protection or optimized-charging features that limit or delay charging under particular conditions. Samsung says battery protection can limit the maximum charging level; the feature’s name and availability vary. Check the battery or charging settings for your model if the percentage stops at a limit rather than continuing to rise. Apple also describes optimized charging for iPhone. A setting that intentionally limits charging is different from a device steadily losing charge, though active use or other interruptions can coincide with it.
When to contact the manufacturer or a repair service
Seek device-maker diagnostics or authorized service if the battery keeps falling with a known-compatible charger and cable, the charging port or accessory overheats, the port is damaged, or battery runtime has markedly worsened. Samsung says persistent charging problems or significantly reduced battery usage time may indicate a hardware issue. Do not buy a replacement battery based on this symptom alone; have the device diagnosed first.
