Never had issues with battery but after the recent Android 10 upgrade it started to darin really quick. I have to recharge phone at 2-3 pm now :(. Did anybody else notice the same issue?
I didn't install any new apps so I'm pretty sure that upgrade caused it.

Have you tried wiping the cache partition since the recent update?
The system cache partition stores temporary system data. It's supposed to allow the system to access apps more quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly.
Follow these steps:
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the Android logo displays, release all three keys.
- An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
- Press the Volume down key several times to highlight wipe cache partition.
- Press the Power key to select.
- Press the Volume down key to highlight yes, them and press the Power key to select.
- When the wipe cache partition is complete, Reboot system now is highlighted.
- Press the Power key to restart the device.
Your phone will take a little time booting up after the cache partition is wiped off of its contents as it will rebuild or recreate those caches. Don’t be alarmed if the phone gets stuck on the logo for a minute or two after this just don’t turn it off so that what was deleted will be replaced successfully. So, wait for your phone to become active. Don’t worry, this procedure is very easy and safe to do. You won’t damage your phone just by wiping the cache partition.
I kept an eye on phone for couple of days after cache reset and unfortunetely it didn't help :(. And more than this my wife's S9 also upgraded and now she has even worse battery drain than I do :(.
So it looks like out phones were killed by updates and they were just 1 year old :((( And warranty is over.
Looks like so :(((
I had the same story with my previous S7, made couple of hard resets but eventually have to drop it and replace by that S9. And now story is repeating with S9. What is the point to ruin phone with OS that can't normally work on it.
UPD: Before hard reset I tried one more thing: forcedly updated all apps and reset cache partition one more time. Surprisingly it helped at least partially. Phone doesn't die in the mid of the day at least.
