iOS - v0.0.13 causes overheating

[molxyz]

Description

Updated to v0.0.13 two days ago. Today I had the app opened from time to time to check on channels, had a few channels in "Pending Open" for the last two days so I was waiting for them to open because I had only one channel open after closing a bunch of them two days ago to test. I could not make a lot of payments so I was just waiting... Then a few hours ago i picked up the phone and felt it was very warm. I turned off the phone, waited for a minute or two, turned it back on but it started feeling warm again, and the battery was getting low.

I turned the phone off again, plugged it in to charge the battery and wait for the phone to cool off. After about an hour I turned the phone on, opened the app again, and the phone got very warm after a few minutes. This is a new XR phone, I don't have cellular service on yet, and didn't have any other app running at the same time the lightning-app was running.

Had no choice but had to delete the app. Will reinstall to test when this issue is fixed.

I've experience this as well. I'm guessing due to lack of optimization @Roasbeef ?

If you try to repro this locally, but with debug logs, what do you see? My guess is that a node on testnet gave you all the prior zombie pruned channels, and your local lnd attempted to validate them all. Validating them requires us to fetch block atm so that can cause quite a bit of CPU and network traffic.

@Roasbeef How do you repro this on the phone and how to get the debug logs on the phone?

Hi @tanx
Sadly to let you know v0.0.14 is still overheating the phone.

@molxyz turning to debug logs is a config value, so it can only be set when we're building the application for distribution. Logs should now be in the settings page on the app.
