With the exception of the SE, Apple Watch Series 5 and later models feature an always-on display. This implies that you don’t need to tap the screen or flip your wrist to check the time. This is made feasible by Apple using some cunning strategies to cut battery consumption, such as reducing the display’s refresh rate from 60Hz (60 refreshes per second) to just 1Hz.
Simply turning off the always-on display and then raising the Watch to wake it will save even more energy. Open the Watch app on your iPhone, select General > Display & Brightness, and then uncheck “Always On” to accomplish this.
Your Apple Watch’s display is a tiny OLED LCD that uses self-emissive technology. Each pixel on an OLED produces its own light. On an OLED, you just turn off the pixels to display black.
This implies that a watch face for the Apple Watch with a lot of empty space should consume less power than one with a lot of bright whites and solid colors. To determine how much of a difference this makes, run some experiments. Use of the Always-On display with a Series 5 or later may result in a noticeable reduction in energy consumption.
The current Watch face can be changed by tapping and holding on it. You can then choose the one you want by simply scrolling left or right, or you can hit the plus sign (+) to add a new one. Simply swipe up and pick “Remove” to get rid of a face you no longer want.
The brightness of the display can significantly affect energy consumption as well. Simply navigate to Watch > Display & Brightness on your iPhone to change it.
For both the Apple Watch and smartphones, push notifications represent a significant energy drain. Not only will doing away with some of these lower energy usage, but it may also increase productivity.
All alerts from your iPhone are automatically mirrored to your Apple Watch. We advise keeping the information you receive on your wrist to a minimum. You can always check it later on your iPhone if it can wait.
Launch the Watch app on your iPhone, select “Notifications,” and then select “Lower Notifications” to reduce the number of notifications you receive from each of the essential Apple services listed at the top. They will be handled in the same manner as they are on your iPhone if not.
You can find a list of third-party programs below these. Switch off any wrist alerts you don’t wish to receive.
The Walkie-Talkie feature on your Watch and answering calls both use more power. The occasional five-minute call won’t significantly drain the battery. It’s preferable to answer the call on your iPhone if you think you’ll be on the line for much longer than that.
Placing your palm over the screen while on a call can quiet incoming calls as well as other notifications like alarms without requiring you to hang up.
Monitoring your heart rate while doing out is one of the best functions of the Apple Watch, but not everyone utilizes it. You can completely disable the heart rate monitor if you’d want to conserve battery life.
Once you’ve done this, your Apple Watch will only track workout-related data like time, distance, and speed.
Open the Watch app on your iPhone, select “Workout,” and then click “Disable Heart Rate Monitoring” to turn the feature off. Turn on “Power Saving Mode” on the following page.
Remember that doing this will result in a less precise estimate of your overall number of calories burned.
If you have Bluetooth-enabled wireless headphones (like Apple AirPods) or a third-party Bluetooth solution, you can sync music to your Watch and leave your iPhone at home. However, if you’re also tracking a workout, this does lead to an increase in battery use.
Even music from services like Apple Music or Spotify can be streamed if you have a cellular Apple Watch. However, this will quickly deplete the battery in your Watch because using mobile data consumes a lot of energy.
If you use these functions and wish to save more battery life, we advise obtaining an arm strap or taking your iPhone with you.
You could even wish to purchase an iPod Shuffle or an MP3 player to use instead.
When you raise your wrist while wearing an Apple Watch Series 4 or before, the display turns on. There is no need to touch or press anything, which makes it convenient for rapidly seeing the time or incoming notifications.
You can disable this feature if you don’t mind touching the screen or using the Digital Crown to check your Watch. Simply open the Watch app on your iPhone, go to General > Wake Screen, and turn off the “Wake On Wrist Raise” setting to do this.
This can be useful if your Apple Watch keeps waking up during the day and drains the battery too quickly. However, if at all possible, we do advise leaving the “Wake On Wrist Raise” setting active.
Complications show data from other apps on the Watch face, like as the current weather or scheduled appointments. Many individuals purchase Apple Watches for this reason alone.
But the more smart complexities you have, the more battery life they might drain. This is because they obtain their data from other sources, necessitating multiple queries from your Apple Watch.
You can disable a complication if you discover that you don’t use it very often. In order to do this, tap and hold the Watch face while selecting edit. Select one after sliding to view the several complexities that are available on your Watch.
You may then use the Digital Crown to cycle through all the options for complications from there.
Some complications, such as the Timer and Stopwatch shortcuts, don’t send out requests for information. Others, however, such as weather predictions or news headlines, frequently do so that they can present the most recent information. Strike a balance since if you have too many of these, your battery life will suffer.
But most importantly, don’t give up any of the features that prompted you to buy an Apple Watch in the first place. A little bit extra battery drain is justified if you depend on having access to information like stock prices or the current temperature on your wrist.
Have you ever wondered how each app ended up on your Watch’s list of installed apps? By default, the companion Apple Watch software is installed whenever you download an iPhone app from the App Store.
Launch the Watch app on your iPhone, select “App Store,” and then turn off “Automatic Downloads” to disable this.
The Apple Watch battery is further depleted by these apps’ potential background information queries. On your iPhone, open the Watch app and select “General” to modify these choices. Toggle-Off “Background App Refresh” if you don’t want an app to periodically wake up and download new data.
Additionally, you might wish to remove any apps you seldom use. On your iPhone, open the Watch app, and then scroll down to the “Install on Apple Watch” list. Tap the app, turn off “Show on Apple Watch,” and then uninstall it.
Bluetooth LE (Low Energy) is the technology the Apple Watch utilizes to connect to your iPhone. The technology in question was created precisely to reduce energy usage. If it’s disabled, the Apple Watch must use Wi-Fi, which uses a lot more power.
Make that your iPhone’s Bluetooth is still turned on. On your iPhone, go to Settings > Bluetooth and turn it on. You may also check “Control Center” and see whether the Bluetooth icon is blue rather than white.
The following four suggestions might not make much of a difference, but if you aren’t using the features they are linked to, you might as well remove them as well.
You can start by turning off the hands-free “Hey Siri” feature. Simply open the Watch app on your iPhone, select “Siri,” and then turn off the “Listen for “Hey Siri”” setting.” If “Raise to Speak” is left turned on, you can summon Siri at any time by just rising your wrist.
Reduced haptic feedback may also help you conserve battery life, especially if you frequently receive notifications. Launch the Watch app on your iPhone, then select “Sound & Haptics” to accomplish this. Disable the “Haptic Alerts” option to completely stop receiving alerts. Additionally, to lessen the impact, select “Default” rather than “Prominent.”
It will use less power if you turn on the theater (the masks icon), do not disturb (the moon), or silent (the bell) modes. Swipe up while looking at a Watch face to get to these.
Theater mode disables Raise to Wake, sounds, and incoming alerts whereas Silent mode mutes all audio and Do Not Disturb disables incoming notifications.
If there is a risk to your hearing from environmental sounds, the noise monitoring feature alerts you. When you are exposed for an excessive amount of time, you’ll receive alerts, and the Health app also lets you keep track of your overall exposure.
Simply turn off “Environmental Sound Measurements” under “Noise” in the Watch app on your iPhone to disable this feature (and maybe conserve some battery life).
You might also want to disable handwashing detection if you’ve enabled it on your Apple Watch because it probably uses more juice.
However, if you’ve tried everything and the battery drain is still too great, you should contact Apple. You might have warranty coverage or you might only only a new battery ($79).
