Does your phone reboot itself so often or are you a real heavy user and the battery just dies suddenly?

I have two Jolla phones in use, although they do get less use because they are used for different tasks. One is for private e-mail, browsing, listening for music and occasionally I might use Alien Dalvik to watch something from Netflix. I use it for authentication too (with mobile certificate). The other one is for business use: employers e-mail, calendar and business calls. I have know to use it for occasional browsing too.

But the uptime on my Jollas is limited only by my ability to connect the charger in time. Usually I do not need to charge them daily, unless I delve into Netflix too deep.
