Which is cool until you find out that it's $350.
That little "Palm" phone only has an 800mAh battery. Smaller display and GPU would help conserve battery but not enough -- it won't last long between charges.
Which is too bad as I really like small phones.
Not exactly. The way this phone is being marketed is very strange - this phone is designed as an "add-on phone", it can only be used as an add-on to an existing line.
As a standalone phone $350 isn't too bad, but asking people to pay $350 in addition to whatever they want to pay for their "main" phone is a little much.
They're in Apple Watch territory with this pricing and I don't think they have the ecosystem to demand that kind of price.
I don't get why people (including TCL and Verizon, it seems!) are calling it a "second phone", as though everyone in their right mind is reading novels on their telephones. At least half of the people I know are considering switching, or already have switched, to a feature phone because new phones have awful, unpredictable battery life and are unwieldy in size (and recently, because most of the things they thought they gained from smartphones seem to come with massive privacy strings attached).
The biggest problem with the TCL Palm, to me (if the standby time is okay, on the order of four days, and it probably isn't with the size of the battery), is that it is locked to Verizon, and only available as a secondary phone; this means I just can't buy or use it right now.
