How to Fix Android Phone Battery Draining Fast (Step-by-Step Beginner Guide)

Why Android Battery Drains So Fast (And Why It’s Very Common)

If your Android phone battery is draining fast, don’t panic — this is one of the most common problems Android users face.

This happened to me personally on my Infinix device, and after fixing it once, I’ve helped many people solve the same issue using the steps below.

Most battery drain problems come from background apps, screen settings, weak signals, or outdated software.

Let’s fix it properly.

Check What Is Draining Your Battery First

Before changing anything, you need to confirm what is using the most power.

Do this:

  1. Open Settings
  2. Scroll down and tap Battery
  3. Tap Battery Usage or Power Consumption

You will see a list of apps draining your battery the most.

If apps like Facebook, TikTok, WhatsApp, or Chrome are on top, that’s usually the reason.

Fix 1: Reduce Screen Brightness (Biggest Battery Saver)

Your screen is often the #1 battery consumer.

Follow these steps:

  1. Swipe down from the top of your screen
  2. Lower the Brightness slider
  3. Go to Settings
  4. Tap Display
  5. Select Brightness Level
  6. Turn on Adaptive Brightness (if available)

This alone can improve battery life immediately.

Fix 2: Stop Background Apps From Draining Power

Many apps keep running even when you close them.

To stop background battery drain:

  1. Open Settings
  2. Tap Apps
  3. Select See All Apps
  4. Tap the app draining battery
  5. Tap Battery
  6. Choose Restricted or Optimized

Do this for heavy apps like:

  • Facebook
  • Instagram
  • TikTok
  • Snapchat

Fix 3: Turn Off Battery Drainers You Don’t Need

Some features quietly drain power all day.

Turn these off if not needed:

  1. Open Settings
  2. Tap Connections or Network & Internet
  3. Disable:
  • Bluetooth
  • Hotspot
  • Location GPS
  • NFC

Location services especially can drain battery fast.

Fix 4: Enable Battery Saver Mode

Battery Saver reduces background activity automatically.

Steps:

  1. Open Settings
  2. Tap Battery
  3. Select Battery Saver
  4. Turn it ON

You can also schedule it to turn on automatically at 20% battery.

Fix 5: Check If Your Phone Signal Is Weak

A weak signal makes your phone work harder, draining battery faster.

If you notice battery dropping quickly when:

  • You’re in poor network areas
  • You’re indoors with low bars

Then try:

  1. Turning Airplane Mode ON for 10 seconds
  2. Turning it OFF again
  3. Switching to Wi-Fi when possible

Fix 6: Update Your Android System and Apps

Outdated software can cause hidden battery bugs.

Update Android:

  1. Open Settings
  2. Scroll to System
  3. Tap Software Update
  4. Tap Download and Install

Update Apps:

  1. Open Google Play Store
  2. Tap your profile icon
  3. Select Manage apps & device
  4. Tap Update all

Fix 7: Restart Your Phone (Simple But Powerful)

Many people skip this, but restarting clears background drain.

Do this:

  1. Hold the Power button
  2. Tap Restart
  3. Allow the phone to reboot fully

This worked for me the first time I had battery drain issues.

Fix 8: Check Battery Health (If Phone Is Old)

If your phone is over 2–3 years old, the battery may be worn out.

Signs include:

  • Battery drops from 40% to 10% suddenly
  • Phone shuts down unexpectedly
  • Battery gets hot quickly

In this case, replacing the battery may be the real fix.

Final Battery Fix Checklist (Quick Recap)

Before you leave, confirm you have done these:

  • Checked Battery Usage
  • Reduced screen brightness
  • Restricted background apps
  • Turned off GPS/Bluetooth when not needed
  • Enabled Battery Saver
  • Updated Android and apps
  • Restarted the phone

This exact process worked for me on my Infinix phone, and I’ve seen it help many beginners restore normal battery life again.
