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.

Hey I just got my iPhone pro 16 yesterday. I unplugged it from full

powrr and it’s down to 75% in 2.5 hours… that will give me 10 of power at this rate! Ridiculous. Can you share how you did the factory reset by computer? I don’t have a Mac so not sure if it would work for me but I would like to try. Does that also then totally reset the phone with none of my setup/downloads etc?

The day after I got it, my battery drained to 70% after 4 hours. Five days later I am down to 45% after 10 hours, so I do think it has been improving over time.

Thanks for the update. That is what is expected and unfortunately we don't get many updates here to confirm that. Some only post when they have a problem, but when it goes away, they don't come back.

It has been 3 days now since I got my iPhone 16 pro and I am blown away by the poor battery life. I believe all the updates and configuring as apple support stated is complete. The phone is no longer running hot. But the battery life is unacceptable. Thinking of returning it. Has this improved for anyone? If yes what did you do ?
