Stop Galaxy Battery Drain: Always On Display
To stop battery drain from the Always On Display (AOD) on a Samsung Galaxy phone, you can turn it off entirely, schedule it to turn off at night, or switch to a simpler clock style that updates less frequently. The AOD is a minor but real power consumer, and the steps below show you exactly how to manage it, plus how to check if it is actually the cause of your battery problems.
What the Always On Display Actually Does
The Always On Display keeps a small portion of your Galaxy phone’s screen lit to show the time, date, battery percentage, and notification icons when the rest of the screen is off. It uses the AMOLED display technology, which only lights up the individual pixels needed to draw that information. Because most of the screen stays black and unlit, the power draw is much lower than a full screen wake, but it is not zero. The phone’s processor, graphics chip, and touch detection also stay in a low-power state to support it, which adds a small, continuous load on the battery.
Samsung offers several AOD styles: tap to show (the default on many models), always show, and show as scheduled. The “tap to show” option is the most battery-friendly because the display only lights up when you touch the screen. The “always show” option keeps the clock and icons visible permanently, which is what most people mean when they talk about AOD battery drain.
How Much Battery Does AOD Really Drain?
On a typical Galaxy phone, the AOD accounts for roughly 0.5% to 1% of battery per hour when set to “always show.” That translates to about 12% to 24% over a full day. However, this figure varies widely based on your phone model, screen brightness, whether you have a moving clock face, and how many notifications you receive (each new notification icon briefly lights up more pixels). For comparison, a single hour of video streaming can use 8% to 12% of battery, so the AOD is a relatively small drain. If your phone loses 20% overnight, the AOD is likely not the main culprit—a background app or poor cellular signal is a more probable cause.
How to Turn Off or Limit AOD on Samsung Galaxy
Here are the exact steps to change AOD settings on a current Samsung Galaxy phone running One UI 5 or 6 (Android 13 or 14). The menu names may vary slightly on older versions, but the path is similar.
- Open the Settings app.
- Tap Lock screen (sometimes called “Lock screen and AOD”).
- Tap Always On Display.
- Choose one of the following options:
- Tap to show – the AOD only appears when you tap the screen. This is the best balance of convenience and battery saving.
- Show as scheduled – set a start and end time (e.g., 7:00 AM to 11:00 PM) so it turns off while you sleep.
- Always show – the AOD is on 24/7. If you want to keep this, consider the next step.
- If you keep it on, tap Clock style and choose a simple, non-animated clock face. Avoid the “Dynamic” or “Photo” styles that change frequently.
- Also, turn off Show notification icons if you don’t need them, as each new icon lights up extra pixels.
If you want to completely disable AOD, simply toggle the Always On Display switch off at the top of the screen.
How to Check if AOD Is Really the Problem
Before you disable AOD, check your battery usage stats to see if it’s actually draining your battery. Go to Settings > Battery and device care > Battery and look at the battery usage graph. Tap “View details” to see a list of apps and features. If the Always On Display appears in the top few items, it’s a significant drain. If it doesn’t appear at all, it’s using less than 1% of your battery, and turning it off won’t solve your battery problem.
Another way to test: charge your phone to 100%, unplug it, and leave it on your desk for an hour with the screen off. Note the battery percentage. Then repeat the same test with AOD turned off. If the difference is less than 2%, the AOD is not your issue.
Common Misconceptions About AOD and Battery
A common misconception is that AOD causes “burn-in” on the screen. While burn-in can happen on AMOLED screens, Samsung has built in a pixel-shifting feature that moves the clock slightly to prevent it, so this is rarely a problem on modern phones. Another misconception is that turning off AOD will double your battery life. As explained, it only saves a small percentage per hour. The bigger drains are screen brightness, background apps, and poor network signal. Also, some users think that “tap to show” still uses battery while the screen is off—it does, but only a negligible amount because the touch sensor is already always listening for taps.
Alternatives to AOD for Checking the Time
If you like the convenience of seeing the time without waking the phone, but you want to save battery, consider these alternatives:
- Use the lock screen notification preview: When you receive a notification, the screen briefly lights up to show it. You can enable this in Settings > Notifications > Brief notifications.
- Use a physical watch or a smartwatch: A separate device takes the load off your phone’s screen entirely.
- Use the “Tap to show” AOD: This gives you the same functionality with minimal battery cost.
- Set a routine: Use Samsung’s Bixby Routines (in Settings > Modes and Routines) to automatically turn off AOD at specific times, like during work hours or at night.
Frequently Asked Questions
Does the Always On Display drain battery even when the phone is in my pocket?
Yes, if it is set to “Always show,” it will keep the screen lit even in your pocket, which wastes battery. However, Samsung’s proximity sensor usually turns off the screen when it detects the phone is face-down or in a dark pocket, so it may not actually be on. To be safe, use “Tap to show” or schedule it.
Will turning off AOD improve my battery life significantly?
Only if your AOD is set to “Always show” and you have a very bright clock style. In that case, you might see a 10-20% improvement over a full day. If you use “Tap to show,” the savings will be negligible.
Does AOD cause screen burn-in on Galaxy phones?
Modern Galaxy phones use pixel shifting and dimming to prevent burn-in. While it is still theoretically possible after years of use, it is rare. Samsung’s AOD designs are optimized to minimize this risk.
Why is my AOD draining more battery than usual after a software update?
After a major update, the phone may re-optimize apps and background processes, which can temporarily increase battery drain. Also, the update might have changed your AOD settings (e.g., reset to “Always show”). Check your AOD settings and battery usage to see if that’s the case.
Can I set AOD to turn off automatically at night without scheduling?
Yes, you can use a Bixby Routine. Go to Settings > Modes and Routines > Routines, create a new routine with “If: Time period” (e.g., 11 PM to 7 AM), and “Then: Always On Display off.” This is more flexible than the built-in schedule because you can also add other conditions like location.
Does using a dark wallpaper help reduce AOD battery drain?
On an AMOLED screen, dark pixels are simply off, so a dark wallpaper reduces battery drain when the screen is on. However, the AOD itself is already mostly black, so a dark wallpaper has no effect on AOD battery usage. It will help with overall screen-on time.
