It can be confusing when your Mac is plugged in but the battery percentage does not move right away. Sometimes the Mac is charging slowly. Other times charging is paused. And sometimes the charger, cable or even the outlet is the real problem.
The good thing is you can check the charging status in a few simple ways. You do not need to guess by only looking at the charger.
This guide explains how to know if your Mac is charging. It covers what the battery messages mean and what to do if your Mac is plugged in but not charging.
Quick Answer: How to Tell If Your Mac Is Charging
The easiest way is to look at the battery icon in the top-right menu bar. If you see a charging symbol or lightning bolt, your Mac is receiving power and charging.
You can also check these signs:
- The battery icon shows a charging symbol.
- The battery menu says charging.
- The battery percentage slowly increases.
- System Settings shows power adapter or charging status.
- MagSafe shows an amber light while charging.
- MagSafe shows a green light when charged.
Do not worry if the percentage does not rise instantly. A Mac can charge slowly if the charger is weak or the battery is warm. It can also happen if the Mac is doing heavy work.
Check the Battery Icon in the Menu Bar
The battery icon is the fastest place to check. It appears in the top-right menu bar on most MacBooks.
The battery icon shows a lightning bolt or charging symbol when your Mac is charging. This means your Mac is connected to power.
Open System Settings and check the Control Center or Battery settings, if you do not see the battery icon. You can turn on the battery status or percentage from there.
This is useful because a Mac can be plugged in but still not charge the battery. The icon and battery menu help you see what is actually happening.
Click the Battery Icon for More Details
Click the battery icon in the menu bar to see more details about power and battery status.
Here is what common messages usually mean:
| Message | What It Usually Means |
|---|---|
| Charging | Your Mac is charging the battery |
| Power Source: Power Adapter | Your Mac is using charger power |
| Not Charging | Your Mac is plugged in but the battery is not charging |
| Battery Is Charged | The battery is full or close to full |
| Charging on Hold | macOS paused charging to protect battery health |
The message can vary depending on your macOS version. But the idea is exactly the same. The battery menu tells you more than the icon alone.
Check System Settings
You can also check the charging status inside System Settings.
Use these steps:
- Click the Apple menu.
- Open System Settings.
- Click Battery in the sidebar.
- Look for battery status, power source and battery health.
- Check if Optimized Battery Charging or charge limit is active.
This is a good place to check if your Mac says Not Charging. It also helps if charging stops before reaching 100%.
You may see battery health information here too. The battery may need attention if your Mac shows a Service Recommended message.
Watch the Battery Percentage
Another simple test is to watch the battery percentage for a few minutes. Your Mac is charging if the number slowly goes up.
But it does not always rise quickly. A low-watt charger will charge slowly. A Mac running video editing or games uses a lot of power while charging.
Running many browser tabs or heavy apps causes the same issue. In that case the battery increases slowly or stays at the same number for a while.
So do not judge in only 10 seconds. Plug it in, wait a little and then check again.
Check the MagSafe Light
The light on the connector can help if your Mac uses MagSafe.
Here is what the MagSafe light means:
- Amber or orange means the Mac is charging or charging is on hold.
- Green means the battery is fully charged.
- Flashing amber points to a possible charging issue.
Your Mac is receiving power if the light is amber. The battery is full if it turns green.
Unplug the charger if the light flashes amber repeatedly. Check the cable and try reconnecting it. There may be charger, port or battery issue if it keeps flashing.
USB-C Charging: What to Check
Many newer MacBooks charge through USB-C. There is usually no light on a USB-C cable. So you need to check the battery icon or System Settings.
Make sure you use a proper USB-C power adapter and cable. A phone charger or a low-wattage adapter might provide some power. But it may not charge your Mac properly while you use it.
Check these things:
- Use a charger with enough wattage for your Mac model.
- Try another USB-C port if your Mac has more than one.
- Make sure the cable actually supports charging.
- Try a completely different wall outlet.
- Avoid using damaged or loose cables.
- Carefully remove dust or debris from the port.
A weak charger makes your Mac say it is connected to power but it will not charge the battery well.
Why Your Mac Says “Not Charging”
Not charging does not always mean your charger is broken. It means your Mac is connected to power but the battery is not receiving a charge at that moment.
Here are the most common causes:
| Cause | What It Means |
|---|---|
| Optimized Battery Charging | macOS paused charging to protect battery life |
| Charge Limit | Your Mac holds the battery below 100% |
| Weak charger | The adapter runs the Mac but cannot charge the battery |
| Heavy usage | Apps use more power than the charger provides |
| Heat | Charging slows down if the Mac gets too warm |
| Battery health issue | The battery needs professional service |
It is completely normal if your Mac says Not Charging only sometimes. You should troubleshoot charger, cable, port and battery if it never charges.
Optimized Battery Charging and Charge Limit
macOS can pause charging to protect battery health. This feature is called Optimized Battery Charging. It learns your charging habits and holds the battery charge before fully charging it later.
Some Macs also use a charge limit feature. This prevents the battery from charging to 100% all the time, reducing battery wear.
So your Mac is not broken if it stops at 80% or 90%. Check your Battery settings. You will see an option to charge to full now if you need 100% battery for travel.
What to Do If Your Mac Is Not Charging
Try these steps in order to fix the problem.
- Check the wall outlet
Plug another device into the same outlet. The outlet is the problem if that device does not work either. - Unplug and reconnect the charger
Remove the charger from the wall and from your Mac. Wait few seconds and then connect it again. - Check the cable and adapter
Look closely for damage or bending. Watch out for burn marks or broken cable coating. Never use a damaged charger. - Try another charger if possible
Use a known-good Apple charger with enough wattage for your specific Mac model. - Try another charging port
Test a different port if your Mac has more than one USB-C port. - Restart your Mac
A quick restart can fix temporary power or software glitches easily. - Check Battery settings
Look for Optimized Battery Charging or Service Recommended messages. - Let the Mac cool down
Close heavy apps and let the Mac rest if it feels hot. - Shut it down for a short time
Shut down the Mac and close the lid for about 30 seconds. Then open it and try charging again. - Reset the SMC on Intel Macs
An SMC reset can help with power issues on older Intel-based Macs. Apple silicon Macs do not use the same SMC reset process.
When to Contact Apple Support
Contact Apple Support or visit a repair provider if the problem keeps happening after basic checks.
Get professional help if:
- The Mac never charges with a known-good charger.
- The charger or the cable is physically damaged.
- The MagSafe light flashes amber repeatedly.
- The battery status shows a Service Recommended message.
- The Mac gets unusually hot while charging.
- The charging port looks broken or loose.
- The Mac turns off even when plugged into power.
Do not keep testing with damaged chargers or cables because that can be unsafe.
Final Thoughts
The easiest way to know if your Mac is charging is to check the battery icon, click the battery menu and open System Settings > Battery. The light on the connector can also help if you use MagSafe.
Slow charging or charging on hold can be completely normal. Check the cable, adapter, port and battery health if your Mac never charges.
Start with the simple checks first. Contact Apple Support if the problem continues before the issue gets worse.
