What is a normal battery usage in UT / FP4 ?

MrRoughwood

Hi,

The discovering of UT on a FP4 is a real 'rollercoaster' to me I played around with the OpenStore apps, struggled with Libertine and Waydroid. It is 1 great candy store Succeeded in configuring GhostCloud, failed with the keepass app.

I'm now curious of what should be normal battery usage in UT on a FP4. Normally I do not have GPS, Bluetooth, NFC, data connectivity active. When I go to bed, I turn off the wifi and have no opening apps. But I was supprised that the battery went from 87% to 59% in the morning. Is this normal behaviour?

I looked, helped by the topics on this forum, to scaling_governor, which is on 'schedutil'. I think this night I will enable the 'flight mode' to check if this makes some difference.

Cheers, Jan

@MrRoughwood You mention having installed Waydroid. Do you stop the waydroid container, either with the waydroid freeze app or with the waydroid stop shortcut that can be installed with the waydroid helper app.?

If you don't do this after having run an app in waydroid, the Android container will keep running in the background and consume a lot of power.

@arubislander Hi, thanks for your reaction. Yes if I do not use Waydroid, I stop the Waydroid container. I read that using Waydroid consumes 'some' energy. Now my phone is 100%, disabled wifi and enabled the flight mode. So I look tomorrow morning if this makes a diffence.

@MrRoughwood That is not normal. I have a battery drain issue on my FP4 as well but it's because of my sim card, for some reason this happens and I have yet to find out exactly why. But without it, overnight usually just drains around 3-10% and that's with Wifi turned on.

May I know if you're on Focal or Noble? Because I'm also seeing a big battery drain on my FP4 with Noble.

Something more technical, thr FP4 actually has a bug where it doesn't actually go to deep sleep. Bur despite that, it has one of the UT devices with good battery. But because of this, if you have things running in the background, it might affect the battery a lot more. Have you installed anything lately? Dekko and UBsync for example have background processes. I have those on my FP4 Focal too though and they don't generally cause huge battery drain.

@kugiigi Hi, thanks for your reply. I'm om focal (20.04) The test of putting the phone at night in 'flight modus', did the trick . From 100% to 98% this morning. Now put the phone in the 2G (power save) mode, so I can check this behaviour. I keep you informed.
Cheers, Jan

@MrRoughwood Yeah, keep on checking different settings. I've done the same when I was trying to figure out my battery drain issue. It needs an overnight test so it takes a long time

@MrRoughwood
Hi there, I am new to Ubuntu 24.04 on a Fairphone 4 and it is indeed very exciting!
But I have a problem with battery drain, too. When I have turned on WiFi and Data Connection - tonight it was 4G - it drains from 80% to 45% within 6 hours.
Even for staying reachable in the night that seems enormous for me.
Turning on the display and using it almost doesnt seem to make a difference batterywise...

Did you try to have only 2G enabled and checked the battery drain for that setup?

Do I have to freeze the waydroid container even when I quitted waydroid?

Should I downgrade to 20.04?

I am using a Fairphone 4 with Ubuntu Touch 24.04 on it, flashed with UBports, but with Android 12 pre-installed instead of Android 11. Even ordered a new SIM-Card for it

Any other clues? Do I have to post more information so you guys can help me? Thanks a lot!!

but with Android 12 pre-installed instead of Android 11

Using another android but the one indicated is a basic in having issues... That nobody will be able to sort out.

@ChevChelios Hi, yes switching to 2G is the trick. I've also upgraded the FP to 24.* the battery keeps real steady.
