Do you know long it can last unplugged answering requests with insomnia?

My old iPad lasts weeks on its battery if I don't use it, I can only imagine it actually sleeps and would not answer network requests in this state.

No idea honestly, but the main reason the battery lasts so long is that it turns the WiFi off, which is why I had to install Insomnia. It was doing fine so far, with 60% battery, but decided to plug it in since it's getting many requests now
