[Update: Jan. 21] Some Google Pixel 6 & Pixel 6 Pro users reporting 'Mobile network standby' draining too much battery

New updates are being added at the bottom of this story…….

Original story (published on November 11, 2021) follows:

The first buyers of the Google Pixel 6 and Pixel 6 Pro series continue to report areas for improvement. You can check the dedicated bug/issue tracker to stay on top of everything.

The most recent reports from users of Google Pixel 6 and Pixel 6 Pro phones indicate battery draining problems caused by the mobile network in standby mode.

Mobile network in standby mode reportedly draining too much battery on Google Pixel 6 series

Some Google Pixel 6 and Pixel 6 Pro users are reporting their phones are suffering from excessive battery consumption in standby mode (1, 2, 3, 4).

When going to the battery section of the system, affected users report that the ‘mobile network’ item is consuming between 30% and 40% of the battery per day.

Is anyone else seeing Mobile network standby using up to 40% battery in the last 24hours?

I have tried numerous things like turning off adaptive connectivity. But the only thing that seemed to reduce it was turning off data completely. It’s odd as the phone should be using wifi, I have noticed the phone disconnects from wifi when locked sometimes so could that be related?

Day three with my pixel 6 pro and I’ve noticed while watching YouTube or anything. Even Chrome or scrolling Reddit the phone gets very hot to the point where when I try to charge it according to Accu battery it says I’m charging at 2-10mA. Anyone else having these issues? I’ve tried turning of 5g because it says mobile network standby is taking up more than 30 to 40% of my battery. Disabling mobile connectivity is not an option because I am on the road so this is strictly on 4G LTE

Some users suspect that the problem would be the Pixel 6 suddenly losing all network coverage and recovering it seconds later. This would happen spontaneously every 2 or 3 minutes.

Constantly losing and recovering the signal put additional strain on the Pixel 6’s modem. So, this would result in the reported excessive battery drain.

Some potential workarounds

Among the reports, there are also possible workarounds that can mitigate the issue. For example, it is recommended to turn off the ‘Adaptive Connectivity’.

Adaptive Connectivity is a feature that automatically switches between WiFi and mobile data networks. This means that the mobile data is always on, even if Wi-Fi is being used.

If that doesn’t work, a more ‘severe’ workaround can be tried. Basically, it is recommended to do a factory reset and configure the phone from scratch, without directly transferring data or saved settings.

Had a very very similar drain (Google Fi here). Tried a bunch of items (disable mobile standby, disable 5g, etc) but in the end, a factory reset and NOT transferring data over seems to have resolved it for me. Used sms backup and restore to get texts, reinstalled all apps manually.

Update 2 (January 01)

07:32 pm (IST): December 2021 update for Pixel 6 users was supposed to fix battery draining issue. But since the update has been shifted to the end of January, users have to wait until then.

Update 3 (January 17)

11:54 am (IST): Users are still reporting excessive battery drain issues with the mobile data network on standby even after the latest update. So, it seems that this issue is still not resolved with January 2022 patch.

Update 4 (January 18)

12:53 pm (IST): Users now seems to be making a direct correlation between the dual SIM/network and the battery draining. According to them, having a dual SIM leads to a more aggressive battery drain.

Update 5 (January 19)

10:48 am (IST): Users who were not having this issue on the November patch have also started reporting it after upgrading to the January 2022 patch.

And with new reports still pouring in, it now seems that the January update has made this bug even worse than before.

Update 6 (January 21)

10:58 pm (IST): Users are now reporting that even after installing the January 2022 update, this issue isn’t fixed. And the only viable solution is to downgrade to the November 2021 patch.
