I have an original Series 1 which I got a couple of weeks after launch. Battery life in the last couple of months has been terrible. I have had OS4 Beta since it was available. I was hoping the GM would eventually fix the poor battery life, but it hasn’t. Turned of various Apps from background refresh. Reduced screen brightness, all that stuff. Full charge, from about 7AM will take me to about 6 or 7PM. Few notification and interactions, but not loads. Anyone with an old Series 1 on OS4 get good battery life ?
