Forerunner 745 - Battery drop on 5.20 firmware

Hello.

On firmware 4.20 my watch was holding ~1.00% hourly drop. After firmware 5.20 arrived, without any usage patterns changes, hourly drop now is ~1.35%.

Is this only my observation (situation) or this is widespread issue?

Thank you.

    Same my battery is also draining a bit faster, I get about a day less in total since the 5.2 update.

    After seeing this I will keep an eye on mine. I charged it to 98% this morning and used it for a ride. I used the save and resume later mode for a few hours and completed my ride later in the afternoon. I'm now on 85%. Not sure if that's good or not.

    I still get about a week using GPS everyday. I keep mine in airplane mode when not working out, PulseOX during sleep only and I don't use any of the smartwatch functions. I use the stock watch face with seconds disabled and the only extras I have installed are the Garmin Running Power data field and Steps to Fit data field wand the Battery Monitor widget. I have noticed that it went from using .1% per hour to .2% just being on my wrist.

    I get about 8 days with lots of gym related workout. I workout almost every day but no gps activities. Maybe a run a month or something. And the rest usual constant hrm, no pulse ox, standard watch face no seconds etc

    FR745 was never advertised as 10 to 20 days so not sure where got that from! If you turn pulse ox on 24/7 and lots of notifications plus use GPS and music (with Bluetooth headphones) it'll last only a few days. 

    I get 4 days or so. Pulse ox off, select notifications only, but lots of GPS plus BT music.

    Mine seems to be specifically at night. It'll drain about 10% during the day with no activities, and then about 20% in 8-9hrs overnight. I've turned off SPO2 altogether so it's not that.

    I have noticed that it shows 'GPS software was updated' basically every time I go to start an activity - so unless Garmin are super agile and rolling out daily updates it could be a problem with that updating and using battery.
