How to check your phone from your watch

Your watch is on your wrist. Your phone is charging in another room, buried in a bag, or face-down on a desk. These short guides cover the everyday questions — and each one starts by explaining what your devices can and can't already do on their own.

How to see your phone’s battery level on your watch

There is no built-in way to see your phone's battery on your watch. Both Apple Watch and Wear OS show you the battery of the watch — not the phone it's paired to.

  1. Install WristBuddy on your phone — App Store or Google Play. The watch app installs alongside it.
  2. Open it once on your phone, so the two can find each other.
  3. Open it on your watch. Your phone’s battery is the first row.

Optional: add it as a watch-face complication so you don’t have to open anything.

The free version shows the battery as a range — below 20%, 20–50%, 50–90%, above 90%. The exact percentage is part of the one-time unlock.

How to tell if your phone is on silent without picking it up

There is no built-in way to check your phone's ringer from your watch. The silent switch is on the phone, and neither watchOS nor Wear OS reports its state to the watch.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone.
  3. Open it on your watch and look at the Silent row. The Focus row (Do Not Disturb on Android) shows whether a Focus mode is running.

Most useful in the thirty seconds before a meeting starts.

One limit worth knowing: if it tells you the phone isn’t silent, you’ll still have to reach for the phone to change it. No watch-based app can flip that switch for you.

How to know when your phone has finished charging

There is no built-in way to see your phone's charging status from your watch. Your watch reports its own charging state, not your phone's.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone, then leave the phone on charge wherever it is.
  3. Open it on your watch. The Charging row shows whether it’s plugged in; the battery row shows how far along it is.

A glance at your wrist instead of a walk down the hall.

How to check if your phone is overheating

There is no built-in way to see your phone's temperature from your watch — and your phone won't warn you until it's already slowing itself down to cope.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone.
  3. Open it on your watch and read the Thermal state row: Normal, Fair, Serious or Critical.

Worth checking when:

  • The phone is charging inside a bag or case, where the heat has nowhere to go.
  • It’s running a hotspot, navigation, a long upload, or recording video.
  • It’s charging in a hot car or sitting in direct sun.

If it reads Serious or Critical, take it out of the bag or unplug it for a while.

How to see whether your phone is on Wi-Fi or mobile data

There is no built-in way to see your phone's connection from your watch. Your watch shows its own Wi-Fi and cellular status, which is often not the same as your phone's.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone.
  3. Open it on your watch. Wi-Fi and Cellular appear as separate rows, and the cellular row also shows the network generation — 5G, LTE and so on.

Useful before heading underground, or when travelling and you want to know whether the phone quietly dropped the hotel Wi-Fi and started using data.

How to check if your phone is locked

There is no built-in way to see whether your phone is locked from your watch. Nothing in watchOS or Wear OS reports it.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone.
  3. Open it on your watch and read the Lock state row.

Handy when the phone is in a gym locker or on a shared desk and you’d rather not go and check.

How to tell if someone has picked up or moved your phone

There is no built-in way to know whether your phone is being handled. Neither watch platform reports the phone's movement to your wrist.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone.
  3. Open it on your watch and check the Motion row.

This is a live reading rather than a log — it answers “is it moving right now”, which is the question that matters when your phone is out of sight.

How to see how far away your phone is

There is no built-in way to measure the distance to your phone from your watch. Precision finding exists for AirTags and similar trackers, but not for the phone your watch is paired to.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone.
  3. Open it on your watch and read the Distance row.

Hardware needed: an iPhone 11 or newer with an Apple Watch Series 6 or newer. On Wear OS, a UWB-capable watch (Pixel Watch 2 or newer). Without ultra-wideband hardware the row won’t appear.

How to read air pressure from your wrist

There is no built-in way to read your phone's barometer from your watch. Some watches have their own altimeter and can show elevation, but not a plain barometric pressure figure taken from your phone.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone.
  3. Open it on your watch and read the Air pressure row, shown in hPa.

Useful for hikers, pilots, and anyone who likes to see the weather turning.

How to leave your phone in another room without losing track of it

There is no built-in way to keep an eye on a phone you've deliberately walked away from. Your watch will relay notifications, but it can't tell you whether the phone is about to die, whether it's ringing, or whether anything has changed.

  1. Install WristBuddy on your phone — App Store or Google Play.
  2. Open it once on your phone, then leave the phone wherever you want it.
  3. Keep the watch on. Glance at it when you choose to — battery, ringer, connection and the rest, all on one screen.

The point is to check once, deliberately, instead of fetching the phone and losing the evening to it.

Frequently asked

Does any of this need an internet connection? No. Your phone and watch talk to each other directly over Bluetooth or your local Wi-Fi.

Will it drain my battery? The phone answers when the watch asks, rather than broadcasting constantly.

Is there a subscription? No. The basic status view is free; the full set of rows is a one-time purchase.

Where does my data go? Nowhere. There’s no account, no cloud and no analytics — everything stays on your phone and watch.

Does it work with any watch? It needs an Apple Watch paired to an iPhone, or a Wear OS watch paired to an Android phone.

WristBuddy is on the App Store and Google Play. See the use cases for the moments behind these guides.
