[TRACKED] After update 20180308 phone won't go to deep sleep

I have a new unit updated to this release and was surprised to see the high battery consumption. It doesn't go to sleep for more than 5 minutes in the 30 hours it took to run down the battery (at least 20 hours those on standby). It would be great if this can be fixed in the next update as it limits the use of the phone considerably. Is it possible to downgrade the phone to extend the battery life in the meantime?

Yeah, downgrading is possibile and will temporary solve such issue.
Remember to perform a factory reset after that!

Thanks. Do you think that this issue will be fixed soon? If the next update is due soon then it may be best to wait.

For the time that it takes, i suggest to downgrade to have your device working as it should

After some time I managed to flash an older ROM onto the phone, the previous version works well. I would say that the guide should point put that there may be a code 10 error with the initial VCOM drivers (but that this doesn't matter) and that during the last few steps of flashing you need to wait until the counter starts before plugging your phone in the second time. At step seven you don't plug your phone in until the checks have been completed. Thanks for the help though

Hello - I confirm the same problem: after the last update FW, my phone does not go into hibernation mode and my battery lasts just 1 day, it consumes 2% battery per hour in standby. thank you for your reply.

If the manufacturer still does not know those phones that had problems with deep sleep on firmwares until 20171219, then the problem of non-transition to sleep on the firmware 20180803 is back, reset to factory settings does not help in any way, phones sleep only on firmwares 20171219,20171227,20180124, this was discussed at 4pda.ru and I thought the manufacturer knew about it.

Nobody posted such issues here, except the openin post of this current topic.
Now tech team is aware of that. Thanks for your precious feedback!

@admin, of course the problem of deep sleep was reported in this forum and you were actively involved in that thread. viewtopic.php?f=191&t=329113

At the time it was solved.... but nobody posted anything else about it for months![/quote]

Most people did not flash on this firmware (20180308), but sat on the previous one, because according to the description it did not carry any significant changes, so no one told you, people checked the firmware just rolled back to the previous releases.

I comfirm this issue. Battery draining a lot faster as it did with older firmware versions.
