Second-Hand iPhone 16 Pro a Good Deal? Battery Drain Concern and Purchase Advice

While buying a second-hand iPhone, full reseted mobile. He charged the phone in the morning to around 80%, and by evening it was showing 56%. I checked the screen time from morning onwards—it had drained automatically and slowly without any active screen time or apps running.

When I went to check the mobile, just 20 minutes of usage caused the battery to drop from 56% to 50%. This was with only basic checking—restarting twice, using the camera, and minimal use.

My main concern is the battery drain. It seems to discharge slowly even when idle. Is that normal or not?

Also, it’s an iPhone 16 Pro, without the original box—only the bill is available. The seller claims he ordered it from the Apple website and showed me the Apple email order receipt. He said he purchased it last October 2024, so it’s about 2 months old and still under warranty.

He is selling it for ₹68,000. Is this a good deal or not? Please reply ASAP :folded_hands:
