Hi!
I also have a Oneplus 5T. Latest UBP.
Without sim card (and thus all mobile data to deal with), the battery is ok : lost 10% after 24h idle.

I understand that "battery saving" cuts mobile data when wifi is available.
Now, the battery will deplete in no time when only mobile data is available.

On my 3rd day with LOS, battery is at 31%.
Though I've spent time away from my wifi servers.

Conclusion (sort of, I'm no dev!!!) : management of sim card by UBP is a battery monger. It's a no-go for me as I often spend time away from my home/work networks.

Works if I answer to myself?

Lduboeuf :
Well, LOS is indeed LineageOS.
All was on, except NFC - no battery saving.
With LOS, having used the gsm (total of 1h30 calls) and played around, still 60% after more than 32 hours.

zubozrout:
Id did RTFM.
Even did a flashall with the latest 9 as per suggestions (before installing something "unusual", I make sure I have a way to revert to initial state).

You guessed I've been rather disappointed.. Would have loved staying with UBP. But I don't mind walking with gsm + ext battery!..

Can't post message : I need "0" reputation...

UBPORT is great. I like the UI/UX.

Now : on a fresh sargo : after 12h00 the battery is at 10%
On LOS : after 24h00, battery reads 75%.

On UBPORTS, sargo was left idle 99% of time.
On LOS : I used it and installed some apps. Idle 95% of time.

I'm not the last one (and surely not the first) to have bought a phone (this one is not a refurb) to test UBPORT on bare metal.

Methink UBPORT should warn the users : not for a daily driver if you expect more than a few hours of work..

@mihael HI!
OTA 2 through installer only..
WAYDROID : flawless install with OTA 1.
Launched under OTA 2 successfully. Now updating the system image...
Working!
Still the same flaw : the bottom buttons are half hidden but functional.
Still, I can't connect to cellular data (Free operator in France) but can't say if it worked with OTA-1.
If anyone has a hint for that..
Have a nice day!

@MrT10001 Hi!
Just did the update with the installer from Pop OS with an AppImage. OTA 2 is now installed and running.
With OTA-1, no desimlock upon boot. Now it works without going through the phone app.
Though, I have no internet connection via cellular.
Are there special settings for the Free operator (from France)?
Have a nice day!!!

@MrT10001 Hello!
I indeed noticed the bin icon and gave it a go.
To no avail.
Will try the installer.
Thanks anyway!

@MrT10001 Hello!
Same problem here!
Log report the absence of key/signature..
And how do you clear the download cache in order to retry download?
Thks!
