Battery drains very quickly even when idle

Is it happeneing after updating to Oreo?

The Oreo update really messed up the battery life*

*To mods: Yes, I have done software repair twice and it didn't help, no it's not rougue unoptimised app I tested without any apps installed and the same is happening, yes Sony is responsible and not Google as Sony chose to release the update and not Google.

same here, drain 98% to 0% and shut off during 13h over night with maybe 15 minutes screen on before going to sleep, awful since Oreo

Maybe a screenshot of settings->battery->tick on battery icon-> make screenshot can give information with which others can help you.

i think better to repair your phone software using xperia companion.
