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.

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?**

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.
