User experience: huge battery drain in Pixel 8 Pro modem Exynos 5300. A developer asked me to open a separate ticket here: https://issuetracker.google.com/issues/361030608#comment8

What type of Android issue is this?

Calls / Voice / Mobile Network

What steps would let us observe this issue?

Go into settings, battery and check usage
Change dropdown from apps to system
You will see high amount of battery used by Mobile Network - Most of the usage is under home WIFI network

What did you expect to happen? Phone modem battery usage should be minimal, due to the fact that internal modem should be in "idle" mode while using WIFI. Instead the usage % is at first place!

What actually happened? The modem seems to have a bug in latest beta firmware and is chewing through huge amounts of battery.

What was the effect of this issue on your device usage, such as lost time or work? High
