Huge battery drain when in airplane mode viewing downloaded manga

[Rowsinator]

Brief summary

I was experiencing an internet issue and due to the circumstances, I decided to put my phone in airplane mode and only view the manga I had saved to my device. My phone got extremely hot, and the battery started to drain very quickly. The same battery drain does not seem occur when connected via Wi-Fi, or via cellular.

If I were to guess, the app is still attempting to make connections even though airplane mode is on. If that's the case, I would have the app check if airplane mode is on and have it stop if it is. It's merely conjecture on my part.

Please let me know if I can do anything else.

My phone is a Samsung Galaxy s10e.

Steps to reproduce

1. Put phone into airplane mode.
2. Turn off Wifi
3. Open Manga saved to local storage using the app.

Kotatsu version

5.3.10

Android version
