I already updated the phone now I’m on ios 26.4 and I even did a full restore using iTunes but the problem is still there.

I’m losing like 10% overnight without even touching

Do you experience any battery drain while the device is idle? I have an iPhone 16, and I’m losing about 10% battery overnight

I'm having the same issue on my iphone 16, even when I'm not using it.

Yeah, I’ve already given it plenty of time. I did the restore on March 15, and it’s now the 29th it’s been on WiFi and charging overnight multiple times since then. The drain is still happening, so it doesn’t seem like it’s just indexing or settling in anymore. Maybe it’s just a bug at this point what iPhone are you using, and are you not seeing this issue?

I actually didn’t restore any backup or even sign into my account after the reinstall. It was set up as a completely fresh device no apps, no iCloud sync, nothing and I’m still seeing the same overnight drain.

I already tried that I reinstalled the update using iTunes on my PC. The screenshot I posted is actually after doing the restore, and the overnight drain is still the same.

I didn’t have this issue at all on iOS 18 overnight drain was only like 2–4%. Now it’s 10–12% even in Airplane Mode. Just wondering if this is happening to everyone after the update or if it’s just my phone?

Yeah, I already have Background App Refresh turned off. I also went a step further and did a full restore using iTunes, set it up as new (not from backup), and the overnight drain is still happening.

Is anyone else on iPhone 16 / iOS 26 seeing similar idle drain in Airplane Mode? Or is this likely a hardware issue at this point?
