There are many complaints about battery drain with WP8.1.
Prior to upgrading my 820 to WP8.1 my battery would easily last me all day. Since the upgrade then my battery is almost flattened between taking it off charge at 7AM and leaving work at 5PM.
However, if I leave WiFi turned off all day then battery is fine. With the original WP8, WiFi was turned off when the screen was locked. I think with the GDR1 update an option was added that allowed WiFi to remain on when locked - I never enabled this feature to try to preserve my battery. With WP8.1 this option has vanished and WiFi, when enabled, is always on even when locked. I have blocked all background tasks and setup mail to sync daily, but WiFi is still left on. I could really do with an option in WP8.1 to automatically turn off WiFi. I know many people who rarely turn their WiFi on (people with unlimited Data contracts), however this would be a pain for me as I have no mobile coverage at home.
So some people are complaining that WP8.1 drains battery quicker and others saying that battery life is same or improved. I wonder if those complaining of excessive battery drain are those who keep WiFi turned on. Lumia 820 users have a pathetically low capacity battery, so WiFi always on seems a real problem.
Has anyone else noticed this ?
