Astept un raspuns...
i'm suffering of the same issue as well. turning off mobile data or staying on wifi is the only thing that "helps" to avoid the issue. really looking forward for a fix from Samsung. Have they actually acknowledged the issue? S8 users seem to suffer from this as well, not only Su and S7 edge.
I returned to Nougat using instructions from sammobile com (select your operator from the "Country" drop down)
Even though I used HOME_CSC OXM to keep my apps and data, I had to factory reset my S7 flat after Odin's action. The return to Nougat went well apart from that. So backup all your data with Samsung SmartSwitch before the operation. Be aware! After factory reset you have to login again in every application/service where you had your account. Quite time consuming:smileyfrustrated:
I have same issue of battery draining too much after oreo update. 6n Standby 06de battery dra5n 6 t6 7% an hour that really bothered me even i am on medium power saving mode but the battery is still draining too much on standby. I have installed oreo 5 days ago now i have to charge my mobile phone 2 times in a day thats really worsen my mobile and experience. Now im waiting for update fix
Unfourtenately Italians versions are also affected by these issues, I am joining to all who is waiting for a soluton :smileyindifferent:
See you soon!
i noticed when i dont use the phone much on the new modem with 3g the cell standby is draining the battery (still acceptable)
on 4g android system is draining the battery
also the google services are draining the battery although i dont have them running at background
Since I downgraded to Nougat, my phone loses about 2% per hour during idle. Overnight it loses about 10-15%. Wifi is ON, LTE is ON, AOD is OFF.
Is it normal discharging speed for Galaxy S7? I'm not saying this is a problem. My phone live longer than 24 hours. I just want to know, is it normal behavior of the phone?
My S7 Flat running a Note 8 7.1.1 ROM drains battery as per the following:
Idle, Wifi, AOD OFF, 0.7%/hr
Idle, Wifi, AOD ON, 1.7%/hr
Idle, LTE, AOD OFF, 1.3-2.0%/hr
Idle, LTE, AOD ON, 2.8%/hr
I hope these stats help.
