Significant Battery Drain with Wi-Fi Enabled on Pixel 3a

[*Enrico13011978*]

@lduboeuf I also think that it is not due to the Wifi. Maybe the user is in a poor mobile network (4G). This is one of the worst battery killers when the device is constantly searching for the mobile network and logging in.

Hello everyone,

I’m experiencing a significant battery drain on my Pixel 3a running Ubuntu Touch. When Wi-Fi is enabled, the battery drops from 100% to 10% in about 6 hours. However, when I turn off Wi-Fi, the battery only drops by about 15% in the same period.

I’ve reset the phone to factory settings and tested again without installing any additional apps, but the issue persists.

Has anyone else encountered this problem or have any suggestions for troubleshooting?

Any background service, custom things that do data exchanges over Internet while you are on Wifi ?
A comparison test could be done by letting cellular data On instead of Wifi.

How can I monitor background services? Do you have a tool suggestion? I did the same test with cellular data and the battery drain was 35%.

Using the phone on cellular consumes less battery than using it on wi-fi.

@furkanonder I know it the other way around from my hardware (Miatool). With the LTE data network or Bluetooth and GPS, you notice that the battery capacity drops more quickly. With WLAN, I have used the device for days without the battery dropping faster. It must be due to your device port. I might have described this problem directly to the porters in the support group. Why the battery drops so quickly is beyond my knowledge. The fact is that this behavior should definitely not be the case. If it was the same with the original firmware, I don't know what to do!

@Enrico13011978 How can I get in touch with the support support group? There wasn't an issue with the original firmware.

@furkanonder You can find various devices in the forum in the support category. Create a new support thread there and wait until someone responds.

@furkanonder As per my experience, I would like inform you that my device's battery has been fully charged in the morning. After 20 min, I have seen battery drain to 96%.

Device's network is set to 4G, where I used it only for calling and texting, internet usage is almost rare on my device, only for updating and downloading Apps.

Therefore, my assumption that 4G network drains the batter fast.

Even though do not have 4G data and do not need to use cellular data while navigating or other stuff.

Try to set it 3G network and monitor your battery consumption.

This issue was discussed here and as a result it was suggested that it be moved here.

[lduboeuf]

@furkanonder Can you give some context, like which version you have, is there anything that you've installed, or any app in background that does not suspend ( via UT Tweak Tool ).
Maybe try on RC ?

As support for your issue already started on your previous thread I don't see why it would be more effective to split the effort... So I merge the two and if you think getting more support in general support and not pixel 3a support section then so be it...

What about my suggestion for trying telegram support channel ?

I mentioned this on the telegram channel, but there is no solution yet.

RC is for "release candidate".
It defines a pre stable testing channel available on any device that has stable channel.

Here is something not normal.
Actually a device running 20.04 stable channel should be on OTA5.

See here, the last RC version is testing pre stable OTA6 (A.K.A. OTA6 "RC"):

Another thing that bothers:

Your device should have this android version installed before installing Ubuntu Touch on it :

Make sure to revert to factory image PQ3B.190801.002 before continuing.
