  • There aren’t, really. There are a few antiques and half baked things.

    A big problem is that these days, unless you’re the size of Apple or Samsung, it’s impossible to get a reasonable hardware soc and modem other than one which only runs a soon obsolete blob laden android which is going to be EOL before you’ve even finished your design.

    The hardware is not there. The firmware/hw data/platform isn’t there even to begin OS work with. And there’s a global shipping, regulation and mobile operator hell waiting on the other side. And a product lifecycle that’s only a few years long.

    Yes, I’ve worked for phone manufacturers.








  • NiCd and NiMH batteries die when left in slow drain devices as the first cell to go empty starts to be reverse charged. These die and often leak pretty fast and you see that all the time if you repair old devices.

    Li packs don’t go empty as the battery protection circuit cuts the slow drain when they reach low water voltage. They are revived when the protection mode charge reaches low water mark again. They’ll be fine unless you leave them for years and years. Even then they generally never leak.
