A couple days ago I updated my Galaxy S7 to the new Android 8.0 Oreo update. Since the update my phone has been draining 1% of its battery after about every minute, the battery will still lose power even if the phone is charging. I have tried to look up similar problems, they do not seem to have the problem of this much of a power loss and I have tried what has been suggested for those kind of problems (checking for applications that can be draining power, changing phone settings to minimize phone usage, removing the GearVR applications, "wipe cache partition", doing a factory reset, and things similar), none of them have worked.
I also think something may have gone wrong while I updated my phone. It seems that there should be new applications added to the phone which I do not see listed. Also, when I do the steps to go to the location where the commands "wipe cache partition" and "factory reset" are located the phone shows a screen saying it's updating, the same screen was originally shown when I updated the phone to the new update, it would eventually go to a screen that shows a dead android icon with the text "no command", this would last a minute or two before finally showing the commands list. This is a problem that stays even after doing a factory reset and I have checked the phone's settings for any available updates, it shows that my phone is "up to date".
Sorry if there is any spelling or grammatical errors, any help would be amazing as it seems it would difficult to reverse the update and I can't really use my phone with the worry that its battery would be ruined from draining its power so quickly.
