How to Extend and Manage Battery Life on iPhone 7 Plus

by

Your iPhone 7 Plus can handle a lot—from streaming videos to gaming and heavy email use—but all that activity can wear down your battery faster. Good news: with a few smart tweaks and habits, you can make your iPhone battery last longer and stay healthier over time.

Here’s your full guide to getting the most out of your iPhone 7 Plus battery.

Optimize iPhone Settings to Save Battery

Adjust Screen Brightness and Auto-Lock

  • Open Settings > Display & Brightness.
  • Lower the brightness manually or turn Auto-Brightness ON.
  • Tap Auto-Lock and set it to the shortest time (like 30 seconds) to save more power.

Turn Off Wi-Fi, Bluetooth, and GPS When Not in Use

  • Settings > Wi-Fi > Turn Off if you’re not using it.
  • Settings > Bluetooth > Turn Off when not needed.
  • Settings > Privacy > Location Services > Turn Off to save battery, especially if you don’t need GPS.

Close Background Apps

  • Double-press the Home button to see open apps.
  • Swipe up on apps you’re not using to close them and free up memory.

Turn Off Background App Refresh

  • Settings > General > Background App Refresh > Turn it Off.

Apps refreshing in the background waste energy even when you’re not actively using them.

Manage Email and App Fetching

  • Settings > Mail > Accounts > Fetch New Data.
  • Turn Push off.
  • Set fetch to Manually or a longer interval like hourly.

The fewer automatic refreshes, the longer your battery lasts.

Tweak Sound and Haptic Feedback

  • Settings > Sounds & Haptics.
  • Turn off Vibrate on Ring and Vibrate on Silent to save extra juice.

Use Low Power Mode

When your battery drops to 20% or lower, your iPhone will suggest Low Power Mode.

To turn it on manually:

  • Settings > Battery > Low Power Mode > Turn On.

This slows down background activities but keeps important things like calls, messages, and internet access running.

Keep Your iPhone Software Updated

Apple often improves battery performance with each iOS update.

To check for updates:

  • Settings > General > Software Update.

Download and install if there’s an update available—just make sure you’re connected to Wi-Fi and plugged into a charger.

Smart Charging Tips to Protect Battery Health

Use Proper Charging Habits

  • Always use the original Apple charger or certified accessories.
  • Don’t charge your iPhone if the Lightning port is wet.
  • Avoid overcharging—unplug it after it reaches 100%.
  • Avoid charging from a computer that’s turned off or in sleep mode.

Ideal Charging Environment

  • Keep your iPhone in a cool, dry place when charging.
  • Avoid charging in hot temperatures (over 95°F or 35°C).
  • Excess heat is one of the fastest ways to permanently damage your battery.

Battery Monitoring

  • See what’s draining your battery:
    • Settings > Battery.
  • Turn Battery Percentage ON to always know exactly how much charge is left.

Bonus Tips for Even Longer Battery Life

  • Condition your battery during the first few cycles: fully charge and fully discharge 2–3 times.
  • If you’re storing your iPhone long-term:
    • Charge it to around 50% before turning it off.
    • Store it in a cool place.
  • Turn on Airplane Mode in low-signal areas to prevent your iPhone from constantly searching for a signal.

Quick Fix if Charging Problems Appear

If your iPhone 7 Plus won’t power on or charge:

  • Hold the Power button for 5–10 seconds.
  • If that doesn’t work, reboot your phone and plug it into a known-good charger.
