I am losing about 10% battery every hour when the watch is just displaying the clock face. Bluetooth and GPS are both off. Didn't have this excessive drain in 7.70. Anyone else?
I agree - seems to be a pretty big jump in the battery drop - i am charging daily now! smh....
not sure what it is - I use a HRM strap and it seems like it is even dropping faster in activities. Plus plenty of times I check the green light activity during times at the office and it's not like it is stuck on 24/7... so not sure whats going on.
I'm experiencing this as well. Updated to 7.8 a few days ago and since then my forerunner 235 battery completely drains in less than 24 hours, where it used to last for over a week! Sounds like a big, not a feature!
By the way, I just performed a reboot (long press on the light button). Other threads suggested trying this, so hopefully this will do the trick.
I'm also experiencing this as well. The battery is completely drained within 4-5 hours of it being full charged. I've spoken to the UK support team, who say that there is no new beta software to try. And I can't downgrade the software to 7.70. I am loathed to do a full blown factory reset as I will loose "my stats race predictor" and "my stats records running" etc
I experienced the same as did my brother in law. The watch went from nearly 1 week on charge to half a day, coincidentally just after a software update - sounds like planned obsolescence to me.
