iPhone 16 Pro Battery Draining Quickly

Iphone 16 pro battery seems so poor. I unplugged my phone at 9:15 am and by 4pm it had only 32% with 3hrs of screen time. I did my 0.5gb update hoping it will extend baterry life and upgrade functionality of my iPhone.

How is it possible? Anyone experiencing bad battery life as well?

Here are a few insights from Apple Support’s official iPhone Battery Drain help page


Did you recently update your iPhone to a new version of iOS? 

  • If you've recently updated your iPhone, battery life might drain faster than usual for a few days. Background tasks like indexing and syncing can temporarily affect performance, so give it time to stabilize.


Battery Suggestions

  • Auto-brightness: Enable auto-brightness to reduce battery usage.
  • Auto-lock: Activate auto-lock to prevent the screen from staying on unnecessarily.
  • Reduce Brightness: Lower your screen brightness if it's set too high.
  • Background Location: Limit location access for apps to "While in Use" to conserve power.


Battery Usage Overview

  • Check Activity & Battery Usage by App: Go to Settings > Battery to see which apps are using the most battery. Adjust settings for apps consuming excess power.


Other Battery Saving Tips

  • Use Wi-Fi: When possible, connect to Wi-Fi, as it consumes less battery than cellular data.
  • 5G Auto (iPhone 12 & later): Enable Smart Data mode to automatically switch between 5G and LTE to save power.
  • Low Power Mode: Activate this mode to reduce power consumption when the battery is low.


Battery Health

  • Check Battery Health: Go to Settings > Battery > Battery Health to see your battery’s condition. If "Service" appears, consider replacing the battery.

Thank you for your feedback! I have also noticed that several people mentioned that performing a factory reset using a MacBook helped resolve the battery drain issue. Could you please provide more details on how to do this and the steps involved? Additionally, are you recommending restoring a backup afterward? It would be helpful if you could share the exact steps you followed, as it might greatly assist others as well.


Thank you!

No torch has been used to 12am until 7am but on the last 24hours it represented 3% of my total activity ! You can see it on my first picture in idle screen time.


I don’t know but my phone battery last as long as my old iPhone 12 that’s not normal… I hope iOS 18.2 will fix it.

i’m gonna try to do what Chillwave said but I’ve already reset my phone with my Mac so I’ll try the others solutions.

There is no straightforward solution unless Apple actually admits that there is a problem. Best is to go through all the posts and you will realise that none of the options actually work in some cases and even if it works, Battery life will be inferior to I phone 13 pro. I have same problem with 16 pro and it will be 3 months since buying it !

Try everything within 14 days and if doesn't solve the problem -please return the phone.
