Battery percentage stuck at the same number?

Your laptop or phone has been plugged in, but the battery percentage has not changed. That can be normal, or it can mean charging has paused, the charger is not supplying enough power, or the battery reading has not refreshed.

Check the battery’s reported charge level and charging state with Battery Meter. It runs in your browser on devices that report battery data, including many laptops, tablets, and phones.

Check whether the battery is charging

Open Battery Meter on the device with the stalled percentage. The tool appears only if your browser reports a battery.
Plug the device into its usual charger and check the charge level and charging state shown by the tool.
Leave the page open and note the percentage. Check again after 20 to 30 minutes, while keeping the device and charger in similar conditions.
If the level stays put, check whether the device has a charge limit, feels unusually hot, or is running demanding apps. Then try a compatible charger and cable if you have one.

A browser reading is a useful clue, not a battery health report. If the browser does not show battery data, use the device’s own battery icon and settings instead.

What the result means

The percentage stays the same, but the device reports charging

The battery may still be gaining charge. The displayed percentage is a rounded estimate, and it may take a while for enough charge to accumulate to move to the next whole number. A device can also update its estimate in steps rather than continuously. Wait longer and compare again before assuming there is a fault.

The percentage stops near 80 or 85 percent

Many devices can limit charging to reduce battery wear, or delay charging based on your routine. If the device is set to stop at a chosen level, this plateau is expected. Check the battery or charging settings before replacing anything.

The percentage stays put and the device does not report charging

The device may not be receiving power, or charging may have paused because of temperature, a charge limit, or a problem with the cable, adapter, or port. A loose connection can let the device run from the charger without adding charge to the battery.

The percentage falls while plugged in

The device is using power faster than the charger is supplying it, or the charger is not being recognized correctly. This can happen during gaming, video editing, or other heavy work, especially with a low-power adapter or a cable that cannot carry enough power.

The level jumps after a restart or reconnect

The displayed estimate may have been stale, or the system may have refreshed its battery reading. If the percentage repeatedly jumps, drops suddenly, or the device shuts down while it still reports charge, the battery or its charge estimate may need service.

How to fix a stalled battery percentage

Check for a charging limit. On Windows 11, open Settings › System › Power & battery for battery information. A charging limit, if your laptop has one, is often controlled in the manufacturer’s app or firmware settings rather than in standard Windows settings. On a Mac, check System Settings › Battery and System Settings › Battery › Battery Health for charging options. On an iPhone, check Settings › Battery › Battery Health & Charging. Android charging options vary by manufacturer, so look under Settings › Battery.
Give the device time to cool. Charging can slow or pause if a phone or laptop is too hot or too cold. Unplug it, move it away from direct sun or a heat source, and let it return to room temperature before trying again.
Reduce power use while charging. Close demanding games or editing apps, disconnect accessories you do not need, and lower screen brightness. If the percentage then starts rising, the charger may be struggling to keep up with the device’s workload.
Check the outlet, adapter, and cable. Try another wall outlet and inspect the cable and connectors for looseness or damage. Use a charger compatible with the device and its charging standard. A low-power USB port or adapter may not charge a laptop reliably.
Reconnect the charger and restart. Unplug it, wait a few seconds, reconnect it securely, and restart the device. This can clear a temporary charging or battery-reading glitch.
Check for system updates. Install pending operating system updates. If the problem began after an update or keeps returning, check the device maker’s support instructions for battery or charging diagnostics.

When it may be a hardware problem

If the battery does not gain charge with a known-compatible charger and cable, try another outlet and remove any dock or hub between the charger and device. A damaged port, adapter, cable, or battery can all cause the same symptom. If the connector is loose, visibly damaged, or hot to the touch, stop using it and arrange service.

Battery Meter can show charge level, charging state, time remaining, and drain rate when the browser provides those details. It cannot measure the battery’s full capacity or confirm that the battery is healthy. If the device still stalls with a working charger, especially if it shuts off unexpectedly or the battery case is swelling, contact the manufacturer or a repair shop. Do not press on or continue charging a swollen battery.

Why a whole percentage can hide a change

The number on screen is an estimate, not a direct measurement of every small change in stored energy. If the device has gained only a fraction of a percent, the displayed number may remain the same. Charging can also slow near a full charge, and battery protection features may deliberately hold the level below 100 percent.

For a fair check, compare readings over time under steady conditions, rather than judging from a brief pause. Keep in mind that a sleeping device or a browser tab that is no longer active may update its reading less often.
