Smartwatch Drains Phone Battery?


Is the battery on your phone running out too quickly? When you have a smartwatch connected to your phone, does it seem like the battery drains more quickly than usual? If that’s the case, you’ll probably enjoy this blog post. Continue reading to learn how much power your watch uses and how different factors can affect the battery life of your phone.

Is it true that wearing a Smartwatch drains the battery on your phone?

Smartwatches connect to their paired phones via Bluetooth, which consumes battery power. Smartwatches do, in fact, deplete the battery of smartphones. Bluetooth, on the other hand, does not necessitate much power. Watches also have GPS capabilities, which means they’re constantly trying to find a signal from satellites while also searching for cellular network data, which can drain a smartphone’s battery.

Smartwatches may be cool (depending on who you ask), but before you rush out and buy one, consider how much worse off your already struggling cell phone will be if you pair it with this new device. This is because the smartwatch not only consumes a lot of power to function properly when connected via Bluetooth, but it also sends that power to the phone.

As I previously stated, Bluetooth requires little battery to connect devices, but that is only true when talking about short-range communication over a few meters. Any more than that, and the constant handshakes start draining the phone faster and faster.

You want to have a fully charged smartwatch for as long as possible to get the most out of it.

Consider charging both devices at the same time if you wear your watch every day and use it often. This implies that when you get home from work, you should charge them.

If charging both devices at the same time is inconvenient, consider using a smartwatch docking station or stand. By not waking up the watch every time you raise your wrist or receive a notification, having them docked and paired eliminates unnecessary battery drain.

With a smartwatch, you can extend the life of your phone.

You can reduce the amount of battery life your smartwatch uses by doing the following:

The always-on display should be turned off.

The always-on screen feature is useful for checking the time on your watch, but it depletes battery life, especially if it’s set to be on all the time. It also means the backlight will remain on, consuming even more energy. Toggle the setting off and on only when you need it, rather than leaving it on all the time.

Disable notification settings.

Smartwatches use Bluetooth to connect to your phone and alert you to calls, texts, emails, and other notifications. To save battery life, you can turn off this feature. Disable the settings for email newsletter updates and social media channels (like Facebook, Twitter, and Instagram), which automatically refresh and update your feed even if you don’t want them to.

Turn off the automatic update checker.

When you use an app on your smartwatch, it will continue to update and sync in the background on your phone. To extend the life of your batteries, follow these steps:

To prevent this from happening, disable auto-update options. To do so,

  • go to your smartphone’s Google Play Store app and select “My apps.”
  • Select ‘Auto update’ from the drop-down menu after tapping the app you’d like to change.
  • To save energy, turn off any apps that do not require updates.
  • Connection alerts should be disabled.

Connectivity alerts can be turned off to save battery life on your smartphone. Scroll down to ‘Connected devices’ or Bluetooth in the ‘Settings’ app on your phone. To avoid searching for nearby smartwatches, speakers, or other devices, turn off these Bluetooth and Wi-Fi settings.

How can you prevent your iPhone battery from being drained by your Apple Watch?

However, it’s possible that the reason for this is unrelated to the smartwatch. Instead, it’s possible that you’ll have to start with your iPhone.

Apple has a suggestion for resolving the issue. To begin, disconnect your watch and iPhone from each other. Then, after a 10-second wait, re-pair them. Rather than simply swapping the two devices back to their original configuration (as Apple previously recommended), you should go through the following steps:

On your iPhone, go to the Watch app. Tap ‘General’ on the My Watch screen. Reset your watch to clear any remaining data. Then press and hold both side buttons until you see “Power Off” followed by an Apple logo on the screen. Restart your Apple Watch by pressing and holding the button for 10 seconds.

That should take care of any issues that were causing your watch’s battery to drain (and, if so, you can turn off this tip). However, it may still occur in some cases. Apple’s first solution, of course, is to reset your smartwatch to factory settings. Not only does this remove any strange bugs, but it also restores several settings to their default settings.

What percentage of your phone’s battery does Bluetooth consume?

This is the most common misunderstanding about Bluetooth technology, as it consumes no power when it is not in use. You can connect your phone to other devices via Bluetooth without draining the battery. Unless you use a Bluetooth speaker to listen to music, in which case both devices’ batteries will be depleted.

Power consumption is highly dependent on the specific use of Bluetooth, as I’ve explained above. Streaming music to headphones, for example, uses more power than Bluetooth LE for a connected smartwatch or location services such as GPS.

It’s also worth noting that power consumption isn’t limited to Bluetooth. A large, brightly lit screen, for example, can be a major power hog (as many smartphones have).

On the one hand, disabling Bluetooth can save you a small amount of energy. On the other hand, you can rest assured that leaving it on will not drain the battery and will make future device connections much easier.

What’s the best way to figure out which app is drained my battery?

For Android: Go to Settings -> Device -> Battery or Settings -> Power -> Battery on your Android device. To keep track of your apps’ battery usage, use this app.


  • Select Settings from the dropdown menu. Select Battery and press the button.
  • Battery statistics can be viewed for the previous 24 hours or the previous 10 days.
  • Swipe down to see the app’s current power usage.

What is the most energy-draining app on your phone?

The most power-hungry of them all is GPS. Because it consumes a lot of power, it is more than happy to eat up your smartphone battery.

When you leave your phone on for an extended period of time or do not use it at all, the GPS is the primary culprit. It can be costly if you don’t use GPS for navigation but still have “location services” enabled. If you’re playing Pokémon Go or using a navigation app, GPS will track your location and update the map as you go. This necessitates a significant amount of power, resulting in increased battery usage.

The brightness of your phone, as well as push notifications, background apps, phone roaming, and Wi-Fi, can all use a lot of power. The amount of energy these items consume is determined by how frequently they are used. If you leave the brightness setting on full and receive hundreds of push notifications each day, for example, you can expect rapid battery drain.

What causes the health of a battery to be compromised?

You should be aware of how quickly a battery’s performance can deteriorate over time. Some things can harm your phone’s battery and cause it to degrade faster than usual:

  • You’re charging your smartphone with the wrong charger.
  • Extremely cold weather.
  • Long periods of time spent in a hot car or in direct sunlight.
  • The brightness of the computer screen
  • Using apps that have not been downloaded from the Apple App Store.


Bluetooth will not deplete your battery in the majority of cases. However, if you use a lot of apps that rely on location services and GPS, it might be a good idea to turn off Bluetooth to save power.

When deciding whether or not to turn Bluetooth off, it’s also important to think about how other factors, such as screen brightness, can affect battery life.
