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 think you have misunderstood us. I have been regularly reporting that I phone 16 pro battery hasn’t been improving with anything -if you don’t use low power mode. It is unfair for you to say that we will report if there is any problem. If we report and if there is a solution- will definitely share. If you are Apple employee- I would recommend to pass it on to high up that Apple may have good customer service, but there has to be a way to allow us to complain.

I have been strong supporter of Apple since 3GS and various MacBooks and ipads- but if they can’t fix battery issue with 16 pro or accept mistake - then no difference with other unreliable mobile phone companies.
