Ok I've got a few questions about the different network types and battery usage.
As far as I know there are 4 different possible scenarios:
3G mode active
3G mode active and connected to mobile data (3G/H showing in notification bar)
2G mode active
2G mode active and connected to mobile data (E or G showing in notification bar)
Currently I have settings default with "Use only 2G networks" unchecked, and "data enabled" unchecked. I have tasker made to automatically turn mobile data on whenever I open any app that may require it, and then turn it off after the app closes, or I can switch it on from the status bar power control.
This is because I assumed having it constantly activated would consume more power. Is this true? does it consume more power having data enabled even when no traffic is going through? If this wasn't the case, I might as well leave it enabled. However with my current system I could still be saving power because if I leave data on, traffic WOULD periodically be used for automatic sync and apps randomly using network and stuff.
The other thing I was wondering about is if there was any major difference in power consumption between 2G and 3G network modes with no mobile data connected. if 2G uses much less power, I could have it set on 2G by default then use tasker to switch to 3G and activate mobile data when opening any internet requiring app. Are there any other advantages of having 3G active over 2G other than mobile data transfer speeds?
Thanks for any help!
Imho your settings are good. Mobile network is one of the battery killlers, so not using (or better using it when you really it), is very good. You are right, 3g has a higher speed on mobile network. Whereas the 2g-network has a much better network coverage. And the permament switch between 2g and 3g drains the battery very fast, too (happens e.g. when you travel).
To sum it up: Use 2g and mobile network off. If you need to use mobile network, turn 3g and mobile network on. Are you done, turn them off again and switch back to 2g.
When you say mobile network, do you mean when an active data connection is enabled?
Because just by the name 'Mobile network", you can be connected to a mobile network for calling and texting etc. without being connected to mobile internet/data.
Is there a difference in call quality between 3G and 2G networks?
Also when toggling between forced 2G only and 3G there seems to be an inactivity period where the reception icon at the top shows like 'disconnected' like it cuts all network communications, then shortly connects again to the specified network type. This delay might be annoying when trying to get internet fast on apps that need it... might not be worth the power saving, if it is only minimal power saving

for the best battery duration, use GSM ONLY!
Hi. I recently switched to cosmote's G930FXXU1DQBQ_G930FCOS1DQB4_COS firmware which supports wifi calling. This firmware also has a VoLTE calls option which is enabled by default. I got wifi and mobile data always "on".
The problem is that every now and then after I move away from wifi coverage, I get no mobile data. The quick way to fix this is to stop and start mobile data or to reboot the device. I have tried enabling and disabling smart switch and aggressive smart switch and disabling wifi calling and the VoLTE calls option. Although it doesn't happen all the time I'd say there is a 50-50 chance to happen.
Thank you for any insights.
This issue was fixed 3-4 days later without changing anything. I believe it was an issue on the providers side (cosmote).
thank you for you help.
Simply put, if mobile data is enabled; mobile hotspots don't work, I get "error". If I enable the hotspot before enabling data then it broadcasts a hotspot fine but after enabling mobile data I get an error. I'm on an EE SIM if it's any consolation.

What kernel? Try another one. Also what ROM?
Hello, i have demo version of p30, removed demo involved apps, enabled fingerprint and face recognition. Problem with mobile network, i can make/receive calls write messages, but after some time it shows: no network, also mobile data on notification shortcut is greyed out and dont work (even its on in settings menu), only wifi. Model: ELLE-L29B 9.1.0.156D(C891E6R2P2).
I found out, that in safe mode everything works fine cellular network and mobile data, so i need disable something that blocks me in demo user.
Is there an app that switches an Android phone between regular mode and dumb 2G mode? I.e. which makes the phone only communicate by 2G phonecalls and SMS, until you re-enable a proper data connection?
I'm using /e/ now but would like the option of becoming a 'dumb' mobile user again temporarily!
