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.

I had the exact same issue. Drove me insane. Battery was terrible, especially while phone was idle. Talked to Apple and they said to bring it in for inspection. I reset the phone (not factory reset) and nothing. HOWEVER, I tried a factory reset via my MacBook, and voila! The problem is gone. Battery is now amazing! Charged my phone 20 hrs ago and it still has 71% left. So, factory reset via your computer. My guess is when they installed software there was some type of error when downloading directly to the phone in the beginning. Hope this helps!
