Have you ever noticed your screen suddenly going dim when your battery gets low? Yeah, it can be super frustrating, especially when you’re trying to read something or show someone a picture.
You’re not the only one. A lot of people run into this, and it usually happens when your phone switches over to Low Power Mode.
So what’s really going on? Well, when your phone or tablet hits that low battery level, it tries to save as much energy as it can. And one quick way it does that is by dimming the screen.
It’s like your phone is saying, “Hey, I’m tired—help me out here.”
But here’s the thing. If you’re outside in the sun or just trying to scroll through something important, a dim screen isn’t helpful at all.
The good news? You don’t have to live with it. There are a few simple things you can do to fix this problem and get your screen brightness back. Even while Low Power Mode is still on.
Stick with me, and I’ll walk you through everything you need to know. You’ll be back to a bright, clear screen in no time.
Why your screen dims when battery is low
Let’s break it down. Your phone isn’t just being annoying—it’s doing what it was designed to do.
But that doesn’t mean you can’t take back a bit of control. Here’s what might be causing your screen to dim when Low Power Mode is turned on.
1. Battery Saver Mode is doing its job
This is the most common reason. When your phone hits a certain battery level, it turns on Battery Saver Mode to stretch out what’s left.
One of the first things it does is lower your screen brightness. It helps, sure—but not when you’re trying to read something or watch a video.
2. Your system settings are taking over
Some phones have built-in settings that automatically dim your screen when the battery drops. It’s a default feature on many devices.
It’s meant to help, but in reality, it can make using your phone harder than it needs to be.
3. Auto-brightness might be clashing with Low Power Mode
Auto-brightness is supposed to adjust your screen based on the lighting around you.
But when Low Power Mode is on, things can get weird. Your screen might end up way dimmer than it should be because both settings are trying to manage the brightness at once.
4. Apps could be messing with your brightness
Yep, some apps ask for permission to control your screen brightness. If they’re not behaving right—or if they’re clashing with your phone’s power-saving settings—they might be making your screen dim without you realizing it.
So now you know the reasons. But don’t worry—we’re not stopping here. Let’s fix this together.
How to stop screen dimming when Low Power Mode is on
Alright, let’s go step-by-step and fix this. These are the most effective things you can try.
I’ll explain everything in a simple way, and if you need to tap around your phone, I’ll guide you through it.
#1. Adjust your display brightness manually
Let’s start with the basics. If your phone is dim, try setting the brightness yourself. Sometimes, that’s all it takes.
Here’s how you do it:
- Open the Settings app on your phone or tablet.
- Tap on Display & Brightness.
- Look for the brightness slider and slide it to the right.

That should make your screen brighter right away. Try it and see how it feels.
#2. Turn off auto-brightness
This one’s important. Auto-brightness can do more harm than good when Low Power Mode is on. Let’s switch it off so you have full control.
Here’s what to do:
- Go to Settings > Accessibility.

- Tap on Display & Text Size.
- Find Auto-Brightness and turn it off.

Now you decide how bright your screen should be, not your phone.
#3. Check if your phone lets you change Low Power Mode behavior
Some phones let you customize what Low Power Mode does. If yours does, you might be able to stop it from dimming the screen. Let’s take a look.
- Open Settings.
- Tap on Battery.

- Look for options related to screen dimming or brightness in Low Power Mode.
If you see a toggle or setting to keep the screen bright, go ahead and turn it on. Not every phone has this, but it’s worth checking.
#4. Look for apps that control brightness
Still having issues? Let’s check if any apps are playing with your brightness settings behind your back.
- Go to Settings.
- Find Apps.

- Look through the list and check which apps have permission to change screen settings.
If one looks suspicious or is using too many permissions, you can either limit its permissions or uninstall it. That might solve the issue right there.
#5. Keep your software up to date
I get it—updates can be annoying. But they really do help. Sometimes, screen dimming bugs get fixed in new updates. So it’s worth checking.
- Open Settings.
- Tap on General.

- Go to Software Update and see if anything’s available.

If there’s an update, go ahead and install it. It might just fix the issue without doing anything else.
#6. Check your screen protector
Believe it or not, your screen protector might be to blame. If it’s too thick or dirty, your screen might look dim, even if the brightness is turned up.
Try this: Clean your screen. If that doesn’t help, try using a thin, anti-glare screen protector. It can make a big difference in visibility.
#7. Keep an eye on battery-hungry apps
Some apps use so much power that your phone might dim the screen just to save battery. Let’s see which apps are being used the most.
- Go to Settings.
- Tap on Battery.

- Look at the list of apps and see which ones are using a lot of power.
If something seems off, try limiting that app’s background activity or replacing it with a lighter version.
#8. Clean up your phone
A cluttered phone can slow things down and mess with your settings. Let’s do a little cleanup.
Delete unused apps. Clear out old files and photos. Restart your phone when you’re done. It’s like giving your device a breath of fresh air—and it might fix brightness problems, too.
The takeaway
Your screen dimming when Low Power Mode is on? Yeah, it’s annoying—but it’s not the end of the world.
Most of the time, it’s just a setting or two that needs tweaking. You’ve now got the tools to take care of it.
To recap: try turning off auto-brightness, adjusting your display settings, and checking if any apps or system settings are interfering.
Don’t forget to keep your software updated and give your phone a little cleanup now and then.
Some people think their phone is broken when this happens. But now you know—it’s usually just a small thing you can fix in minutes. So don’t stress. You’ve got this.
