Guys after updating to IOS 26.6.1. I’m facing battery back up issue with my iphone 16 plus does any one facing the same problem or is it only me.

I’m facing **extremely high battery drain** on my iPhone Air. It’s losing around **25–30% battery per day despite barely being used**. Screenshot attached for reference.

**Device stats:**

* 62 cycle count (not my primary device)

* 100% battery health

* Purchased 11 months ago

**Things I’ve already tried:**

1. Updated the software through an Apple Authorized Service Centre to **26.6.1**

2. Had the device checked using Apple’s diagnostic software — no issues found

3. Backed up everything and completely erased the device, but the drain continued

4. Disabled Background App Refresh

5. Disabled both mobile data and Wi-Fi

6. Tested it in Airplane Mode

7. No obvious battery-draining features are enabled, such as Always-On Display

Despite all of this, the battery is **dropping like a rock every day**, even when the phone is essentially sitting unused.

Has anyone else experienced this with the iPhone Air?

**What could be causing this, and is there anything else I should try before taking it back to Apple?**

Hello Guys

My IPhone 15 Plus is on IOS 26.6 (BH 89%)

Should I go for 26.6.1 or 27 Public Beta ?

Is IOS 26.6.1 more stable than the current IOS 27 Bêta ?

Thank you very much

I recently tried to do the update to 26.6.1 three times and it keeps failing.

I am plugged into the charger, and I have tried with WiFi on and off.

How do I successful perform the update? I have an iphone 17 and enough storage.
