My Redmi Note 13 Pro 4G Battery Drains Rapidly Even with Light Use

I recently purchased a Redmi Note 13 Pro 4G, and the battery drains alarmingly fast. Even with minimal usage, like reading on Twitter, the battery percentage drops significantly. I’ve read similar complaints online, with some users claiming the issue resolves itself after a week, but so far, there’s been no improvement for me.

For reference, I purchased this phone from Media Markt, so it is a legitimate, warranty-covered device—not a grey-market product. A brand-new phone should not have such battery issues, and I expect Redmi to address this promptly. If this persists, I will demand a replacement or repair under warranty. I need a resolution for this frustrating problem immediately.
