What f(x)tec euphemistically refer to as a "sleep state" means nothing else than that the battery erroneously got depleted to literally 0.0 V, so that there is no energy whatsoever left in it. The "battery protection" system should normally prevent this from happening. Not only is so deep discharging bad for a Li-battery's life expectancy, it also turns out that Android actually always needs enough residual charge left to boot its kernel before re-charging from USB can start. So, yes, once bitten by the battery depletion bug, there is no other way than to either 1) send the phone back

It looks like you've run into the dreaded battery protection issue. Most Pro1xs are fine when delivered. Even sitting for a year in the warehouse, the batteries should have 30-50% charge (Mine, delivered in early April 2023 had 50% charge), but the battery protection apparently has a flaw they are investigating. If the battery becomes somehow completely deleted, it enters a sleep state and won't charge. You should contact FxcTec at info@fxtec.com to open a support ticket. Sorry 😞
