Where to find Battery Saver in Settings
Battery Saver (also called Battery Optimization, Power Saving Mode, or Low Power Mode depending on your phone brand) lives in your Settings app under Battery or Device Care. The exact path varies by manufacturer — Samsung calls it Power Saving Mode, Google Pixel calls it Extreme Battery Saver, and other brands may use different names — but the principle is the same: you turn it on and off from the same menu where you found it.
Open Settings, then look for Battery, Battery and Device Care, or Device Maintenance. Tap into that section. You will see a toggle or button labeled Battery Saver, Power Saving Mode, or Low Power Mode. If the toggle is on (usually shown in blue or green), that is why your phone is running slower or dimmer than usual.
Key Takeaways
- Battery Saver is a toggle in your Settings app under Battery or Device Care, and turning it off takes one tap.
- Different phone brands name this feature differently — Samsung uses Power Saving Mode, Google Pixel uses Extreme Battery Saver — but the location and method are similar across all Android phones.
- When Battery Saver is on, your phone limits background activity, dims the screen, and slows performance to stretch battery life.
- You can turn Battery Saver back on anytime, and some phones let you set it to turn on automatically at a certain battery percentage.
The step-by-step process for most Android phones
Open the Settings app (the gear icon on your home screen or app drawer). Scroll down and tap Battery or Battery and Device Care — the exact wording depends on your phone model. You should see a section labeled Battery Saver, Power Saving Mode, or Low Power Mode with a toggle switch next to it.
If the toggle is blue, green, or shows "On", tap it once. The toggle will turn gray or white and show "Off". Your phone will return to normal performance when ready. You do not need to restart your phone or confirm anything — one tap is all it takes.
If you cannot find Battery Saver in the Battery section, try searching for it instead. Open Settings, tap the search icon at the top, and type "battery saver" or "power saving mode". Tap the result that appears, and you will land on the same toggle.
What Battery Saver actually does when it is on
Battery Saver restricts what your phone can do in the background. It limits app refresh, slows down your processor, reduces screen brightness, and turns off some wireless features like Bluetooth or location services. The goal is to make your battery last longer when you are running low on charge.
This is why your phone feels sluggish or the screen looks dim when Battery Saver is active. Apps take longer to open, scrolling may feel less smooth, and some features may not work until you turn Battery Saver off. Once you disable it, all of that returns to normal.
Automatic Battery Saver settings you can adjust
Many Android phones let you set Battery Saver to turn on automatically when your battery drops to a certain level — usually 15 or 20 percent. This happens without you having to do anything, which is why some people are surprised to find it on.
If you want to change when Battery Saver turns on automatically, go back to the Battery or Device Care section in Settings. Look for an option called "Turn on automatically at" or "Auto-enable". Tap it and choose a different percentage, or turn off automatic set up entirely so Battery Saver only turns on when you manually enable it.
Why your phone might have turned Battery Saver on by itself
If you did not turn Battery Saver on manually, your phone probably activated it automatically because your battery level dropped below the threshold you set. Check your current battery percentage — if it is below 20 percent, that is likely why Battery Saver is on.
Some phones also turn Battery Saver on after a software update or if the phone detects unusual battery drain. If Battery Saver keeps turning itself back on even after you disable it, your battery may be aging and losing capacity. In that case, turning Battery Saver off will work, but your phone will drain faster than it used to.
Turning Battery Saver back on when you need it
You can turn Battery Saver back on anytime by following the same steps: open Settings, go to Battery or Device Care, and tap the toggle to turn it on. This is useful if you are away from a charger for a long time and want to stretch your battery life.
Some phones also let you turn Battery Saver on from the Quick Settings panel at the top of your screen. Swipe down twice from the top to open Quick Settings, look for Battery Saver or Power Saving Mode, and tap it. This is faster than going through Settings if you need to toggle it on and off frequently.
Frequently Asked Questions
Will turning off Battery Saver drain my battery faster?
Yes. Battery Saver limits background activity and processor speed to extend battery life. When you turn it off, your phone uses more power because it can run at full speed and apps can refresh in the background. If your battery is already low, you may notice it drains noticeably faster.
Can I turn off Battery Saver if my phone is at 5 percent battery?
Yes, you can turn it off at any battery level. However, your phone will drain much faster without Battery Saver active, especially at very low percentages. If you turn it off when your battery is critically low, you may only have a few minutes of use before your phone shuts down.
Does Battery Saver delete my files or data?
No. Battery Saver only changes how your phone uses power — it does not delete anything. All your files, photos, messages, and apps remain on your phone. Turning it on or off has no effect on your data.
Why does my screen look different after I turn off Battery Saver?
Battery Saver dims your screen to save power. When you turn it off, your screen brightness returns to whatever you had set before Battery Saver was on. If the brightness still seems wrong, you can adjust it manually in Settings under Display or Screen Brightness.
Can I set Battery Saver to turn on at a different percentage?
Yes. Go to Settings, tap Battery or Device Care, and look for an option like "Turn on automatically at" or "Auto-enable Battery Saver". Tap it and choose a different percentage — you can usually pick anywhere from 5 to 50 percent depending on your phone model.
