Good afternoon,

I'm new to this forum and I don't know if I'm posting in the appropriate section. Please, relocate my post if necessary.

I'm quite a newbie regarding phone hacks but I can make my way through the various general processes related to phone updates.

I recently updated my Galaxy A40 to Pie (A405FNXXU2ASJ1, Oct. 2019) [update: after checking on the official Samsung website, I updated the original April version of Pie with the August update and the battery issue started aftewards] and the battery started discharging way faster since then. I'm really not satisfied with this issue and I would like to do something to solve or improve battery life.

I tried Package Disable Pro and disabled a few apps and packages, although I don't really know which services to disable exactly. I also added most apps to the standby app list in the developer options, but it didn't improve the situation as much as I expected. I used to charge my phone every 24 hours or so with Wi-Fi on all the time, no Bluetooth or NFC.

Would anyone have an idea to get a similar battery life (charge once per 24 hours) or explain to me how to restore Oreo (downgrade or flash).

Thank you very much for your help

just check in the battery section of settings what app is using most battery and disable it. Also check what is running in the background

I have already tried that with no success. Thanks for your answer.
