Sadly, this is a continuing story. Since the upgrade to Tampella 5.0.0.72, I’ve had to restart my C2 six times because of sudden battery drain, which I believe relates to the connectivity issue.
Only two of these restarts have been good ones, letting the phone run normally for at least 5 days (I’ve had 10 days and 8 days, with some instances of WLAN not connecting or not switching to cellular, that I could fix without restarting.) My Xperia 10-II often ran 30 days or more without a restart, and I don’t think its battery ever discharged suddenly, with no activity.

I really like my C2, it’s just the right size for me, has a good screen, runs apps my Xperia 10-II couldn’t (old Android). But it has these ongoing problems with basic functions, making me feel it’s unreliable. I do hope the next software release has a solution.
