iPhone 16 pro max-256GB battery draining fast

This is normal. When you first setup a new iPhone, there are certain tasks that run in the background where you can experience an increased battery drain. One of these main tasks is indexing, which is sorting your millions of bytes of data on your new iPhone. When the setup is complete, which usually takes a few days but depends on the amount of data you have, your iPhone will return to normal conditions.

Hello,

With all due respect I do not believe the app has to be deleted, the Facebook app does drain a decent amount of battery life but going to the web version is a sacrificed experience which I don’t believe should be present on a brand new device. I do believe there is some other variable draining the battery. If the user likes to use Facebook mobile app, then they should enjoy it!

Hope that helps,

Thanks Everyone

Greetings,

I wonder if this has anything to do with the device software since it is a new issue, upload the battery screenshot as advised by Zachyy but I am also curious about what version of IOS your device is running, as of today you should be on Verison 18.3-(22D63). If you are running any beta software or or possibly if you use the device alot in very cold or very hot weather it could potentially affect it. Additionally, while they may not seem like it, features like Apple Carplay drain ALOT of battery.

Hope that helps,

Adin

All rechargeable batteries are consumable components that become less effective as they chemically age.

Recent software updates can accelerate that process by adding features that consume more power.

As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged.

Apple won’t replace the battery until it reaches 80% capacity.

Li Ion (Lithium Ion) batteries have recharging capabilities; however there are limits.

I recommend to slow charge your iPhone to maximize the charge capacity, battery health and efficiency. ⚡️🔋

NOTE:

Capacity loss in standby applications is largely determined by temperature.

Charge above -30°C and discharge below 55°C for best results.

• Check battery health and usage.
• Optimized Battery Charging.
• Maximizing Battery Life.
• Use Low Power Mode.
• About battery usage.
• Show battery percentage.

The first thing I noticed was that Facebook is consuming the most battery. Facebook’s app has been known for major battery consumption, and it’s recommended to delete the app and use a browser instead to access it.

Hello~ If you’re past the 14 day return period …that’s not an option. Click on below and review…

Also the apps that you’re using are well known resource/battery consuming hogs… complain to those app developers if it makes you feel better…

Thank you for your reply. I had the same thinking but since it’s more than a month or 2, it’s still the same which made me skeptical about the device.

In that case, please upload a screenshot of your iPhone battery usage. You can do so in Settings > Battery. Here’s mine.
