Essentially, an Apple Watch uses these green LED lights to detect the amount of blood flow and this is then used to help determine the actual heart rate. At times when the watch is taking more frequent heart rate measurements, the green LED lights will be even more active.May 13, 2021
The green LEDs are used by the heart rate sensor. It is normal for the sensor to take background measurements of your heart rate regularly throughout the day, but the LEDs do not remain permanently lit for this purpose.
The small red dot icon (which may appear, to some users, to be green) at the centre top of the watch face indicates that you have one or more unread notifications.
That green light is from the sensor on the back of the watch that measures heart rate. You can turn it off by disabling heart rate monitoring. This can be done using the Watch app on your iPhone. Go into the Privacy settings under “My Watch.” You should then be able to disable the heart rate monitoring there.
On your Apple Watch, tap Settings > General > Reset > Erase All Content and Settings. Type your password if prompted. … If you want to pair your Apple Watch and iPhone again, keep your plan. If you don’t want to pair your Apple Watch and iPhone again, remove your plan.
If the screen flickering issue is caused by a bug in the watchOS software, updating your device should instantly fix it. Launch the Apple Watch app on your iPhone, and go to My Watch. … Then go to iPhone Settings, tap General, and select Software Update. Restart your devices again and check if the issue persists.
If it’s completely dead, it takes about 90 minutes for a full charge. It doesn’t matter if it’s a Series 1, Series 2, or an original Apple Watch; they all take 90 minutes to go from 0% to 100%.

In 2 to 12 hours, the watch should switch into its normal mode and begin normal charging (which will last much longer the first time). After it’s fully charged and operational, I’d recommend doing full reset via its menu, to decrease the chances of getting that annoying error again.
4 green dots on your screen indicates that your Apple Watch is connected to a mobile network.
You cannot disable the dot since it’s part of an Apple privacy feature that lets you know when apps are using different parts on your phone. Go to Settings > Accessibility > Display & Text Size and toggle on Differentiate Without Color to change it to an orange square.
To force restart your Apple Watch, press and hold both the side button and Digital Crown for at least 10 seconds, then release both buttons when you see the Apple logo.
If water splashes on to your Apple Watch, wipe it off with a nonabrasive, lint-free cloth. Don’t use heat, compressed air, or sprays. Clean and dry your Apple Watch, the band, and your skin after workouts or heavy sweating. After swimming, gently rinse Apple Watch Series 2 and newer with warm tap water.
The new Retina display on Apple Watch Series 7 has nearly 20 percent more screen area than Series 6.
Restart both your iPhone and your Apple Watch, turning both off together and then restarting your iPhone first: Restart your iPhone, iPad, or iPod touch – Apple Support. Restart your Apple Watch – Apple Support. If the issue persists, next close open apps on your iPhone and then restart both devices again.
Look at your Apple Watch display. If there is a lightning symbol, that means that your watch is charging. If you start charging your watch when the battery is completely depleted, it might take a while for it to turn on and display the charging symbol.
Apple has outlined that the Apple Watch battery is designed to retain up to 80% of its original capacity at 1000 complete charge cycles, which gives the watch’s battery a lifespan of about two-and-a-half to three years based on fully charging the wrist-worn device once per day.
In terms of your battery lifespan, you would want to maintain a charge of 75% to 25%. This is because Apple watch uses Lithium-Ion batteries, which work in charge cycles, each time you consume a charge cycle your battery capacity gets lower and lower.
You’ll see a blue arrow at the upper-right corner of the screen if an app or complication recently used location services. If you’re using Wi-Fi instead of your iPhone, the blue Wi-Fi image will appear here.
If you camera is in use or was recently recording, you’ll see a green dot. If both are in use, you’ll see the green camera dot. So if you use an iPhone and want to know if your phone is listening or watching, glance at the upper-right corner. If you see the small green or orange dot, your microphone or camera is on.
The orange light dot on iPhone means an app is using your microphone. … For example, if you’re recording a reminder using the Voice Memo app, the orange dot will appear. The orange dot also appears when making phone calls or using the Siri function.
