If you’re frequently finding your Apple Watch SE 2 dying before the day ends, you’re not alone. Battery life can be tricky especially when notifications, workouts, and background sensors are running full steam.
One of the most efficient ways to conserve battery is enabling Low Power Mode on your Apple Watch SE 2.
If you haven’t checked out the Apple Watch SE 2 Comprehensive Guide, it offers an excellent foundation before diving into specific settings like battery optimization.
Let’s explore how to enable, customize, and make the most of Low Power Mode.
What is Low Power Mode?
Low Power Mode extends your watch’s battery life by disabling or limiting power-hungry features like:
- Always-On Display
- Background heart rate monitoring
- Workout auto-detection
- Incoming call & notification checks
Even with these features off, your Apple Watch will still provide essential functions like time, activity tracking, and emergency SOS.
How to Turn On Low Power Mode
Option 1: From Control Center
- Swipe up from the bottom of the watch face
- Tap the Battery Percentage icon
- Toggle Low Power Mode
- Confirm by scrolling and tapping Turn On
Option 2: During a Workout
- Open the Workout app
- Start your desired workout
- Tap the three-dot menu > Toggle Low Power Mode
Low Power Mode during workouts disables continuous heart rate and GPS tracking but still records basic stats.
Customize Low Power Mode
Want to avoid enabling it manually every time? Here’s how to make it seamless:
- Open Settings > Battery > Low Power Mode
- Select Turn On Automatically for workouts or battery below 20%
- Schedule it with Focus Mode for sleep or meetings
When to Use Low Power Mode
- Battery drops below 30% midday
- During long flights or travel days
- Overnight without charger
- During extended workouts without GPS tracking
What You’ll Temporarily Lose
When Low Power Mode is on:
- No Always-On Display
- Delayed background app refresh
- No irregular heart rhythm notifications
- No environmental noise detection
Yet for most users, this trade-off is minimal compared to the battery boost.
