How to Make Your Phone Battery Last Longer

Do you notice your smartphone battery draining rapidly, leaving you with a dead phone before the end of the day? It is incredibly frustrating when your phone dies, especially when you are out running errands and need it for navigation or calling for a ride.

Many seniors believe that a fast-draining battery means the phone is broken or needs to be replaced. However, in most cases, your battery is fine. It is simply being overworked by background tasks, high screen brightness, and unnecessary location tracking.

In this guide, we will show you simple, free setting adjustments that can dramatically extend your battery life on both iPhone and Android devices.

1. Turn Down Screen Brightness (The Biggest Battery Drain)

Your phone's large, bright screen uses more battery power than almost anything else. If your screen is set to maximum brightness all day, your battery will drain in a few hours.

How to adjust brightness:

  • On iPhone: Swipe down from the top-right corner of the screen to open the Control Center. Locate the bright vertical bar with the sun icon and drag it down to a comfortable, lower level.
  • On Android: Swipe down from the top of the screen to open the notification panel. Drag the horizontal brightness slider to the left to lower it.
  • Turn on Auto-Brightness: Go to your phone's display settings and enable "Auto-Brightness" (or "Adaptive brightness"). This allows your phone to automatically lower the brightness in dark rooms and raise it only when you are outside in bright sunlight.

2. Turn Off Location Services for Useless Apps

Many apps (like shopping apps, games, or social media) constantly run your phone's GPS in the background to track where you are. This constant tracking uses massive amounts of power.

Keep GPS active for safety: While you should block location access for shopping apps and games, make sure to keep location services active for navigation apps (like Google Maps) and safety apps so you can get help in emergencies.

How to manage location settings:

  • On iPhone: Go to Settings ➡️ Privacy & Security ➡️ Location Services. Scroll through the list and change apps you don't need location for to Never or While Using the App.
  • On Android: Go to Settings ➡️ Location ➡️ App permissions. Tap on individual apps and select Allow only while using the app or Don't allow.

3. Use "Low Power Mode" (Your Emergency Button)

If your battery drops below 20% and you are away from home, both Apple and Android have an emergency battery-saving mode that temporarily shuts down all non-essential features to keep your phone alive.

How to enable Low Power Mode:
  • iPhone: Go to Settings ➡️ Battery ➡️ toggle on Low Power Mode. Your battery icon in the top corner will turn yellow.
  • Android: Go to Settings ➡️ Device Care (or Battery) ➡️ toggle on Power saving.

4. Reduce Screen Timeout Time

If you set your phone down and walk away, how long does the screen stay lit up before turning off? If it stays on for 5 or 10 minutes, you are wasting battery.

  • On iPhone: Go to Settings ➡️ Display & Brightness ➡️ Auto-Lock ➡️ change it to 1 Minute or 30 Seconds.
  • On Android: Go to Settings ➡️ Display ➡️ Screen timeout ➡️ select 30 seconds or 1 minute.

The Bottom Line

Your phone's battery is designed to last. By lowering your screen brightness, stopping background GPS tracking for non-essential apps, reducing screen timeout, and using power-saving modes when low, you can easily get through the day without searching for a charger. Take 5 minutes to adjust these settings today and enjoy a longer-lasting phone!

How to Cancel Cable TV & Switch to Streaming

If you are still paying a hefty monthly bill for cable TV, you are not alone. Many households pay upward of $100 to $200 every single month for hundreds of channels they never actually watch.

How to Cancel Unwanted Phone Subscriptions

Have you ever looked at your bank statement and noticed a small, recurring charge for an app or service you don’t remember signing up for? It is incredibly common. Many modern smartphone apps lure users in with a "free trial." Once the trial ends (often in just 3 or 7 days), the app automatically starts charging your credit card on file, sometimes $5, $10, or even $15 every month. Because these charges are billed directly through your Apple or Google account rather than the app itself, canceling them requires going into your phone's main settings. In this guide, we will show you exactly how to find, manage, and cancel these hidden subscriptions on both iPhone and Android devices. Part 1: How to Cancel Subscriptions on an iPhone (iOS) Apple manages all subscriptions purchased through the App Store in one centralized location on your phone.
