Warning! S23ultra users - the last September security update messed up the LTE modem
Long story short, after the September security update, my phone started to drain overnight 8x faster than before...I was losing 2-3% overnight, now it went to 20%.
I wiped cache partition, went to great lengths factory resetting the phone, put it in safe mode to rule out a rogue app...NOTHING.
In a moment of desperation, I set the bands to WCDMA/GSM only and the drain is gone!!
Note that I have 5 LTE bars at home (band 12, RSSI > -95dBm) so signal strength has NEVER been a problem in the 5 years since I joined Videotron. I'm not on a Partner network at home.
The only rational conclusions that either Videotron made changes to the modem code, or Samsung did and it affected Videotron bands.
Either way, no one tested this seriously before blasting it to unsuspecting customers.
Kira can we please ensure that next time around, this issue gets addressed and tested? I spent a ton of time troubleshooting, so I'd rather not do it again.
It would be a lot easier to just change carriers.
I'm available with a ton of notes and information if someone technical wants to get in details.
BTW, I work for a telecom equipment manufacturer.
Well, between Scamsung and Videotron I'm left on my own to try to solve the problem. Expected.

- Unsure why you tagged me but i have an 23Ultra as well with said septembre patch and have not noticed this behavior.
Outside of that, asking that this gets addressed and tested is not something i can do. I'm just a forum user at this point.Duh, I misinterpreted "Super utilizateur" thinking you're a Videotron mod. I'll tag CharlesR, maybe he can help.
No harm done, spread the word of you can 🙂
PS. The issue is probably related to the specific band in use in my area (Ottawa West). It does seem that the phone keeps reconnecting all night to the tower.
I could try to force it on a Partner network and see if that changes anything. Band 12 is the strongest in my area, I saw it trying 4 and 66 but at 20dBm weaker signal.
Hello Ipse, sorry about this situation. There is no need to tag moderators, we review all the forum posts.
As Kira confirmed they are not facing this issue on their device of the same brand and similar model, it looks like a specific problem on your cellphone. I have shared your feedback with the relevant team and it will be investigated. In the meantime, please feel free to contact Samsung so they can also look into it.Have a nice rest of your day.
Edit: could you please send us a PM with your phone number so we can contact you?
