ios 16.1.2 battery draining(iPhone 13)

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.

Battery Performance Tips:

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

I'm having battery drain on my (newer) SE. It happens overnight. It will drop 20-30% or more.

Try: Double check your spotlight searching. (This is similar to your macbook & indexing of content). You can disable the ability for Spotlight to search/index apps on a case by case basis. That might help w/battery drain. (I just did this and I'll see if it works).

Settings> Siri & Search and then scroll down to all your apps that are listed. Go into each app and then de-select "Learn from the App" and "Suggest App".

It could also have to do with the number of photos on your phone & the new ML algorithms that categorize photos. The more photos one has, then longer the categorization process takes. Delete duplicates and maybe offload those photos to cloud storage.

Let's hope this works.

I updated to 16.2 and I’m having the same issues I watched my phone go from 83% to 81% skipped over 81% and as I write this it just went down to 80%. My iPhone is at 100% battery capacity so I don’t know what’s going on or why it’s draining so fast. When I went out to run errands my phone was at 97% I’ve been out for maybe 2 hours if that it shouldn’t be down to 80% already and it’s on battery saver mode so it shouldn’t be doing this so fast

Your battery is doing great. You do not need to worry about the battery.

My battery health is 89% and I have an iPhone 13 Pro Max.

I agree with Bob, you are good to go! 😉
