The quickest way to see your battery percentage
Swipe up from the bottom of your Apple Watch screen to open Control Center. The battery percentage appears in the top right corner as a number with a small battery icon next to it. This is the fastest way to check your charge level at any moment.
If you have an Apple Watch Series 9 or later, you can also glance at the watch face itself — some faces display the battery percentage directly on the screen without needing to open Control Center. Check your watch face settings to see which ones offer this option.
Key Takeaways
- Swipe up from the bottom of the screen to open Control Center, where the battery percentage displays in the top right corner.
- Some Apple Watch faces show battery percentage directly on the watch face if you enable it in the face settings.
- The battery icon changes color as your charge drops — green means above 20%, yellow means 10 to 20%, and red means below 10%.
- Low Power Mode extends battery life by limiting background activity and can be turned on manually or automatically when your watch reaches 10% charge.
Using the watch face to display battery percentage
Open the Watch app on your iPhone and go to Clock. Select the watch face you currently use, then tap Edit. Scroll through the available complications — these are the small widgets that appear on your face — and look for one labeled Battery or Battery Percentage.
Tap the complication slot where you want the battery to appear, then select Battery from the list. Save your changes by swiping left and tapping Done. The battery percentage will now show on your watch face without needing to open Control Center.
Not all watch faces support battery complications. If you do not see a Battery option in your complications list, try switching to a different face that supports more customization, such as Modular, Infograph, or Solar.
Understanding the battery color indicator
The battery icon in Control Center changes color to show you how much charge remains. A green battery icon means your watch has more than 20% charge. Yellow appears when your battery drops between 10% and 20%, signaling that you should plan to charge soon.
Red indicates your battery is below 10%. At this point, your watch will enter Low Power Mode automatically unless you have disabled this setting. When Low Power Mode is active, your watch limits background app refresh, reduces motion, and disables some features to stretch the remaining charge.
Turning Low Power Mode on and off manually
Open Control Center by swiping up from the bottom of your screen. Look for the battery icon with a lightning bolt through it — this is the Low Power Mode button. Tap it to turn Low Power Mode on or off.
When Low Power Mode is on, the button appears highlighted or in a different color depending on your watch model. You can turn it on manually even if your battery is above 10%, which is useful if you know you will not be able to charge your watch for several hours.
Low Power Mode stays on until you turn it off manually, even if you charge your watch back to full. If you want your watch to return to normal performance automatically, you will need to disable Low Power Mode in Control Center.
Checking battery in the Watch app on your iPhone
Open the Watch app on your iPhone and tap the My Watch tab at the bottom. Scroll down and select Battery. This screen shows your Apple Watch's current battery percentage and also displays the battery level of any paired accessories, such as AirPods or a wireless charging case.
This method is useful if your watch is not with you or if you want to check the charge before you put it on. The battery percentage updates whenever your iPhone and watch are in range and connected.
Battery drain and what uses the most power
Constant heart rate monitoring, GPS tracking during workouts, and always-on display drain your battery fastest. If you notice your watch losing charge quickly, check whether you have enabled the always-on display in Settings. Turning this off can add several hours to your battery life.
Background app refresh also consumes power. Open the Watch app on your iPhone, go to General, then Background App Refresh, and disable it for apps you do not need to update in the background. Reducing notifications and disabling Bluetooth when you do not need it also helps extend battery life between charges.
Frequently Asked Questions
Why does my Apple Watch battery drain so fast?
Always-on display, GPS tracking, and constant heart rate monitoring are the biggest power drains. Disable always-on display in Settings, turn off background app refresh for apps you do not use often, and limit GPS workouts if your battery is draining faster than expected. Older watch models also drain faster than newer ones.
Can I see battery percentage on older Apple Watch models?
Yes. All Apple Watch models show battery percentage in Control Center when you swipe up from the bottom. Older models may not support displaying battery percentage directly on the watch face, but you can always access it through Control Center or the Watch app on your iPhone.
What happens when my Apple Watch battery reaches 0%?
Your watch will power off completely. When you charge it again, it will restart. If your watch is paired with your iPhone, you can still locate it using Find My even when the battery is dead, as long as it is within range of another Apple device.
Does Low Power Mode affect the accuracy of my workouts?
Low Power Mode disables some background features but does not prevent you from recording workouts. However, GPS tracking may be less accurate because the watch limits some processing power. If accuracy matters for your workout, consider turning off Low Power Mode temporarily.
How long does an Apple Watch battery last on a full charge?
Most Apple Watch models last 18 hours on a full charge with typical use. Newer models like the Series 9 and Ultra can last longer. Heavy use with GPS and always-on display can reduce this to 12 to 14 hours, while Low Power Mode can extend it to 36 hours or more.
