iPhone Battery Draining Fast? Here’s Why and How to Fix It – A Kiwi’s Guide

 

Your iPhone Battery Is Draining Fast, And It’s More Common Than You Think.

 

Waking up to a full battery and finding your iPhone dead before the day’s half done? You’re not alone. Across New Zealand—from students in Dunedin to busy professionals in Auckland—fast iPhone battery drain is a frustratingly familiar problem. Whether you're navigating work tasks, messaging friends, or filming content on the go, a fading battery is more than inconvenient—it’s disruptive.

At Phone Surgeons, we’ve repaired thousands of iPhones, and battery complaints are among the top issues we see in our repair shops. But here's the good news: not only do we know what causes these battery drains, but we also know exactly how to fix them—fast, reliably, and affordably.

Let’s break down the real reasons your iPhone battery might be draining quickly—and how you can solve it.

Why Is Your iPhone Battery Draining Fast?

 

 

Too Many Apps Running in the Background

Many apps refresh data, even when you're not using them.

What to do:

• Go to Settings > General > Background App Refresh
• Turn off refresh for unnecessary apps

High Screen Brightness

Your iPhone screen is one of its biggest power hogs.

Fix it fast:

• Go to Settings > Display & Brightness
• Enable Auto-Brightness
• Or manually lower your brightness
  
  

Battery Health Is Degraded

Every iPhone battery wears out over time. Once your battery’s health drops below 80%, you’ll see faster drains and slower performance.

Check it:

• Go to Settings > Battery > Battery Health & Charging
• If it says “Service,” it’s time for a battery replacement

Tip from Phone Surgeons:

Our expert technicians can replace your iPhone battery the same day in most cases—no appointment needed.

Software Settings That Could Be Draining Your iPhone

 

 

Push Notifications and Auto-Fetch Emails

Every time your phone checks for a new email or social update, it consumes power.

Solution:

• Go to Settings > Mail > Accounts > Fetch New Data
• Change from “Push” to “Manual” or “Every 30 Minutes”
• Limit app notifications to essentials via Settings > Notifications

Location Services Always On

GPS tracking is great for Maps, but a drain when left on for all apps.

Fix it:

• Go to Settings > Privacy > Location Services
• Set apps to "While Using the App" instead of "Always"
• Disable “Precise Location” for apps that don’t need exact tracking

Connectivity Features That Can Drain Power

 

 

Weak Wi-Fi or Mobile Signal

When your phone struggles to connect, it works harder—and drains faster.

Smart tips:

• Use strong Wi-Fi connections when available
• In low-signal areas, consider enabling Airplane Mode
  
  

Bluetooth and AirDrop Running Unnecessarily

Leaving Bluetooth or AirDrop on when unused adds up in battery consumption.

Solution:

• Swipe down to Control Center and turn them off when not in use

iOS Updates and Bugs

Post-Update Battery Drain

Sometimes, a new iOS version can temporarily reduce performance and battery life.

Why does it happen?

• System tasks may still be completing in the background
• Some older apps may not yet be optimized for the new iOS

What to do?

• Wait 48–72 hours for post-update activity to settle
• Make sure all apps are up to date
• Consider a full restart after major updates

Advanced Battery Fixes for Power Users

 

 

Turn on Low Power Mode

Low Power Mode helps by reducing background activity, brightness, and visual effects.

How to enable:

• Go to Settings > Battery > Toggle on Low Power Mode

Reset Settings

Sometimes, a glitchy setting is the real culprit.

Try this:

• Go to Settings > General > Transfer or Reset iPhone > Reset All Settings
  

This won't delete your data but will reset preferences like Wi-Fi and notifications.

Still Struggling? It Might Be Time to Replace the Battery

 

 

Even with the best settings, a battery that’s aged or damaged won’t hold power like it used to.

How to know it’s time for a replacement:

• Battery health below 80%
• Your iPhone shuts off unexpectedly
• It takes longer to charge or drains too quickly after charging
