Apple iPhones Battery Draining Fast: How to Fix It Yourself
If your iPhone battery drains too fast, it's usually caused by a rogue app, bad settings, or an old battery. The great news is that most fixes are free software changes. You can check your battery's health right in your settings to know if it needs replacing.
⚠️ Safety First
- Never puncture or bend an iPhone battery — they can catch fire.
- If your battery is swollen or bulging, do not try to remove it yourself. Take it to a professional immediately.
- Only use batteries designed for your specific iPhone model.
Parts You May Need
Step-by-Step Repair
- 1
Check your battery health
Go to Settings > Battery > Battery Health. If Maximum Capacity is below 80%, your battery is worn out and should be replaced. If it's above 80%, the problem is likely software — keep going with the next steps.
- 2
Find what's draining your battery
Go to Settings > Battery and scroll down to see which apps are using the most battery. If one app is using way more than the others, that's your culprit. Try deleting and reinstalling that app.
- 3
Turn off background app refresh
Go to Settings > General > Background App Refresh. Turn it off for apps that don't need to update in the background (most of them). This stops apps from running when you're not using them.
- 4
Reduce location tracking
Go to Settings > Privacy & Security > Location Services. Set most apps to 'While Using' instead of 'Always'. GPS is one of the biggest battery drains. You can also turn off Location Services completely to test if it helps.
- 5
Lower screen brightness and enable Auto-Lock
Swipe down from the top right to open Control Center and lower your brightness. Then go to Settings > Display & Brightness > Auto-Lock and set it to 30 seconds or 1 minute. Your screen is the single biggest battery user.
- 6
Reset all settings if nothing else works
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won't delete your photos or apps, but it resets Wi-Fi passwords and customized settings. It fixes many hidden software issues that drain battery.
If That Didn't Work
- A recent iOS update can sometimes cause temporary battery drain for a day or two while the phone re-indexes data.
- Weak cell signal forces your phone to work harder, which drains the battery much faster.
- Push email (checking for new mail constantly) uses a lot of battery. Switch to fetch every 15 or 30 minutes in Settings > Mail > Accounts > Fetch New Data.
When to Call a Professional
If your battery health is below 80%, replacing it yourself costs $12–$30 for the part. Apple charges $89–$119 and third-party shops charge $40–$70. If you're not comfortable opening your phone, a shop replacement is worth the money — it's quick and they'll guarantee the work.
