There are multiple reasons found over internet and also listed by the techies about battery been draining fast. The common reasons are the unwanted features and apps running in background. Many users do not know about these things and always complaints about the issues on social media groups or to the customer support.

Let’s take a look about different reasons of iPhone 16 battery draining.

1. iPhone 16 Settings

There are a number of options which we don’t need in our daily routine or required for few timespan. But we left these options always turn on which consumes the battery fast.

Features like Bluetooth, GPS, Personal Hotspot, Wi-Fi etc. decrease the battery life quickly if left always ON. Also screen related features like brightness settings impact the overall battery life.

2. Background Apps

There are lots of apps that runs in background without any notice and these drain the phone’s battery. Many social media apps like X, YouTube, Instagram, Whatsapp, Snapchat or other build in or third-party apps like fitness app, news app, weather app run in the background continuously and consumes battery.

3. Poor Battery Health

This is also an important factor to check. Physical part also matters for the life. If battery is damaged or stopped charging after some %age, it gives a sign that the battery has some issue and you need to change it.

Check the battery health in Settings > Battery > Battery Health & Charging. If degraded, consider a replacement.

4. Software Updates

Everyone knows the software updates are important. In each software update many bugs are resolved and many features are updated. But if there is any problem in the software update then it will start consuming battery quickly. A poorly optimized software update increases device resource usage, consuming more RAM and CPU power, which leads to faster battery drain.

As discussed on Apple forum, even the software update is bug-free, it consumes battery for a day or two because an update may trigger some re-indexing or other background maintenance tasks. The same case recently faced by many iPhone 16 and iPhone 15 users when they updated the device with iOS 18. As per the report, users were experiencing unexpected battery loss, even during light use.

5. Other Reasons

As we mentioned, there is no single reason for battery drain in iPhone 16. As technology improved, new technology was implemented, new reasons also emerged that consumes the phone’s battery and these reasons are:

• Always-On Display: In new models, even if you turn off display – some part of display is still active that shows time, day, date,  app notifications, battery percentages etc. This is 1 main reason, the battery drains even if you don’t use the phone or it is on standby mode.
  
• High Refresh Rate: Earlier the phone comes with 60Hz refresh rate, but for better view and smoother visuals the refresh rate increased from 60Hz to 120Hz and it consumes more power. Though iPhone 16 has 60Hz, but pro variants comes with 120Hz (pro motion), and there the battery drains quickly!
  
• Poor Network Signal: With the deployment of 5G network, and as the iPhone 16 is 5G, the battery will be consumed in much faster way. The 5G network is not stable (some area where the 5G signal is weak), hence it shifts from 5G to 4G and then 4G to 5G and this drains the phone’s battery quickly.
