I haven't measured it yet.

But battery life has always been bad (I don't go out without a 10,000 mAh power bank and a charger) and depends heavily on usage: When the phone is on standby, it works for almost two days and when in use, it lasts not much more than two hours (guesstimate) - so I really would have to do a controlled experiment to gauge the impact.

But at least battery life has not become so much worse that I would have noticed an obvious difference during the ten days since I made the change. The crashing modem had made the phone completely unreliable; now the phone is usable. So it's definitely a good trade from my perspective.

Not conciously, no. Are there any (besides the "Settings" menu)?

Of course you won't notice the difference as much if you actually use the phone because that will drain the battery in no time with both settings.

Unfortunately, I will have to stick to the "on" setting since otherwise the modem will crash so often that the phone is actually unusable.

Or does anybody have a fix for BOTH problems so that I would not have to choose between short battery life and a permanently defunct modem?

Sometimes it works, mostly it does not. A restart usually helps, but of course that's not what you want to do when you need to quickly look something up or when you or wait for a Signal/Telegram message while on the move. The problem occurs with two different providers.

Is there anything I can do?

For some reason there are two APNs from my provider (O2 Germany) in Settings/Mobile Network/Access Point Names: There is "pinternet.interkom.de" and there is "internet". When I don't have a data connection, I have to switch to the respective other APN and everything works. I have no idea what it depends on and of course this workaround is not ideal, but it's at least less tedious than restarting the phone and hoping that it will work.

I found that out after I had followed zetabeta's advice to set ATTR{power/control}="on" instead of ATTR{power/control}="auto" in the first line of /usr/lib/udev/rules.d/80-modem-eg25.rules (reboot afterwards or make udev load the new rules). This minimises the notorious modem crashes (in fact I hardly had any crashes since changing it), which is great in itself; I'm not sure whether it contributed to the fact that I have mobile internet.

Anyway: My pinephone is now perfectly usable.
