What are the easiest methods to check the battery level on an Apple Watch running the latest watchOS?

Based on the available support pages and community reports for the latest watchOS, here are the simplest ways to see your Apple Watch battery level:

• Control Center – Press the side button to open Control Center. The battery percentage is shown right at the top [1][6][11]. Tapping the percentage gives you more details and a quick way to turn on Low Power Mode [11].
• Watch‑face battery complication – Add a battery complication to your watch face so the charge level is always in sight, no taps needed [3][7][14]. (Third‑party apps like Battery Grapher and BatteryPhone can provide extra complication styles, such as “hours until 0%” [25][31].)
• iPhone battery widget – Add a battery widget to your iPhone Home Screen or Lock Screen; it can show your connected Apple Watch’s charge level [4][15][20]. On some newer watchOS versions (e.g., watchOS 26), the Lock Screen widget may stop showing the watch automatically [33]. To fix that, edit the widget, turn off “Automatic”, and manually select your Apple Watch [40][41].
• Nightstand mode while charging – When your watch is on its side and charging, a charging icon appears. Tap that icon to see the current battery percentage [5][16][21].
• Settings app – Open the Settings app on your watch and go to Battery. You’ll see the exact percentage, a charging history graph, and the last charge time [2][8][10]. This takes a few extra taps but gives you the most detail.

The quickest day‑to‑day methods are Control Center and a battery complication, since they work with one press or at a glance. Siri does not appear in the evidence we reviewed, so it may not be a supported way to check battery on the latest watchOS.
