How to Enable Advanced Battery Mode on Android

Does your Android die halfway through the day? I was in that boat for months until I figured out how to enable advanced battery mode on Android, a feature most users don’t even know exists. In this guide I’ll walk you through finding it and setting it up to squeeze every last percentage out of your battery.

What is the advanced battery mode on Android?

Advanced battery mode isn’t a single toggle. It’s a set of hidden options within Android’s settings that let you precisely control which apps consume energy, when processes get killed, and how power management works in the background.

Since Android 12, Google has been packing more tools under the “advanced battery usage” umbrella, and in Android 15 and 16 things have gotten noticeably better. The problem is they’re scattered across multiple menus and not always easy to find.

I’ve been using these options since the Pixel 6 and now on a Galaxy S25, and I can tell you the difference in battery life is significant when configured properly.

How to access advanced battery settings

I’ll cover the two major Android flavors: Samsung (One UI) and stock Android (Pixel and similar).

On Samsung (One UI 7)

1. Open Settings → Battery and device care
2. Tap on Battery
3. Look for Background usage limits (it’s somewhat hidden)
4. Inside you’ll see options to restrict apps individually

You can also go directly from Settings → Apps → select an app → Battery and choose between “Unrestricted,” “Optimized,” or “Restricted.”

On Pixel and stock Android

1. Go to Settings → Battery
2. Tap on Battery usage
3. You’ll see detailed per-app consumption
4. Select any app and change its behavior

Pro-tip: On stock Android, “Adaptive Battery” uses AI to learn your habits. Leave it on, it works quite well after about a week of learning.

On Xiaomi (HyperOS)

1. Settings → Battery → More battery settings
2. Look for Battery saver for apps
3. Set per-app restrictions from there

Key features of advanced battery mode

There are four main tools you should configure if you want to maximize your Android’s battery life.

1. Background app restriction

This is the most powerful one. You can choose which apps can run in the background and which ones get killed when you close them. I restrict social media apps like Instagram and TikTok, which are absolute battery vampires.

2. Adaptive Battery

Android learns which apps you use most and prioritizes them. Apps you don’t use get put to sleep faster. It’s a set-it-and-forget-it system, but it needs a few days to learn your patterns.

3. Custom battery saver mode

Don’t confuse this with basic battery saver. Custom mode lets you choose exactly what to limit: 5G, sync, location, vibration, max brightness, etc. I have one set up that only limits 5G and reduces brightness to 70%, giving me an extra hour of use.

4. Optimized charging

It learns your charging routine (say, you charge overnight) and slows down charging to avoid keeping the battery at 100% for hours. This extends your battery’s long-term lifespan.

Warning: Don’t put ALL apps in restricted mode. If you restrict messaging apps like WhatsApp or Telegram, you might miss important notifications.

Advanced settings by brand

Each manufacturer has its own extra tools. Here are the most useful ones:

Samsung One UI

• Sleeping apps: Puts unused apps into hibernation after X days
• Processing mode: Switch between “Optimized,” “High performance,” or “Light.” Light mode throttles CPU and saves significant battery
• Battery protection: Caps charging at 80% to extend battery lifespan

Xiaomi HyperOS

• Autostart: Controls which apps can launch on their own
• Lock screen: Kills apps when you lock the phone
• Smart battery saver: Automatically adjusts based on your usage

Google Pixel

• Adaptive Battery: The smartest implementation on the market in my experience
• Extreme Battery Saver mode: Limits to essential apps and extends battery up to 48 hours
• Adaptive charging: Learns your sleep schedule

Extra tricks that complement advanced battery mode

Once you’ve configured the advanced battery mode on Android, these tricks give you that extra push:

1. Disable constant Wi-Fi scanning: Go to Settings → Wi-Fi → Preferences → turn off “Wi-Fi scanning always available”
2. Reduce screen refresh rate: 60Hz instead of 120Hz saves 15-20%
3. Disable or schedule Always-On Display: You don’t need it when the phone’s in your pocket
4. Review location permissions: Many apps request “always” location when they only need “while using”
5. Use dark mode: On OLED screens it saves real power, not just aesthetics

I apply all these tweaks and consistently get a day and a half out of my Galaxy S25 with moderate use, when before I couldn’t make it past 14 hours.

Advanced battery monitoring: tools and apps

Once you’ve configured advanced battery mode, it’s a good idea to monitor how your battery evolves. Android includes native tools, but third-party apps can give you more detailed information.

Native Android tools: In Settings → Battery → Battery usage you can see detailed per-app consumption, battery voltage, temperature, and health status. On newer phones with Android 15+, you’ll also find information about completed charge cycles and remaining capacity.

Recommended third-party apps:

Of all of these, the one that’s helped me most is AccuBattery. What it does particularly well is measure your battery’s real capacity compared to the original factory capacity. After a year of use, most batteries lose 5-10% capacity, and this app shows it to you precisely.

AccuBattery standout features:

• Measure how much energy your battery actually receives per charge
• Monitor charge speed in real time
• See how much each app individually consumes
• Alerts when battery reaches a specific percentage (very useful for capping at 80%)

Pro-tip: Enable the 80% charge alert in AccuBattery. When it sounds, unplug the charger. This significantly extends your battery’s long-term lifespan. Most manufacturers now offer this feature natively, but AccuBattery actively reminds you.

Battery myths on Android you should ignore

There’s a lot of outdated or outright false battery advice circulating online. Let’s debunk them:

Myth 1: “You should fully drain your battery before charging” This was true with old nickel-cadmium batteries. Modern lithium batteries don’t have “memory effect” and work better if you charge them frequently between 20% and 80%.

Myth 2: “Charging overnight damages the battery” Modern phones stop charging when they hit 100%. The problem isn’t charging overnight — it’s keeping the battery at 100% for hours. Optimized charging solves this by slowing down the charge to reach 100% right when you wake up.

Myth 3: “Third-party battery saver apps work” Most “booster” or “RAM cleaner” apps are useless or even counterproductive. Android manages memory much better than any external app. Use the system’s native tools, which are designed specifically for your hardware.

Myth 4: “Dark mode always saves battery” Only on OLED screens. On LCD screens, dark mode doesn’t save power because the backlight is always on. If your phone has an LCD display, the savings are purely aesthetic.

Myth 5: “Manually closing apps saves battery” Partially false. Android automatically puts apps to sleep when you’re not using them. Manually closing them and reopening them later can consume more energy than leaving them in the background, since the system has to reload them from scratch.

FAQ: Frequently Asked Questions

Does advanced battery mode slow down my phone?

Not necessarily. Background app restriction might make some apps take a second longer to open, but it doesn’t affect overall system performance.

Will I lose notifications if I restrict apps?

Yes, it’s possible. Apps like WhatsApp or Telegram need background access to deliver notifications. Put them on “Optimized” instead of “Restricted.”

Does Adaptive Battery work from day one?

No. It needs roughly a week to learn your usage patterns. During those first days, battery savings might be minimal.

Is capping charging at 80% worth it?

In the long run, yes. Lithium batteries degrade less when not kept at 100% for extended periods. Short term you lose 20% capacity, but your battery will last more years.

Conclusion

Knowing how to enable advanced battery mode on Android makes a real difference in your daily use. It’s not magic, but combining background restrictions, adaptive battery, and optimized charging can add hours to your battery life. Spend 15 minutes configuring it and you’ll notice the change from day one.
