High power consumption in HIBERNATE with 3.3v poer

Firmware
1

Using Boron LTE 402
V5.4.1

When the power supply drops to 3.3V the power consumption in the hibernate mode goes to 470uA rather than ~120uA.
Does anybody know how to fix this or what's causing it? Concerned that as the device's battery decreases, it might start to consume more and more power.

I am using the OTII power supply
Hibernate power consumption per voltage:
3.75v 119uA
3.6v 121uA
3.5v 467uA
3.4v 936uA

Code:

SYSTEM_MODE(AUTOMATIC);
SYSTEM_THREAD(ENABLED);

void setup() {
}

void loop() {
    waitUntil(Particle.connected);
    // Change the sleep mode accordingly
    System.sleep(SystemSleepConfiguration().mode(SystemSleepMode::STOP).gpio(D0, FALLING));
}

The Boron cannot be powered at 3.3V on VIN or Li+. The modem requires 3.6V to operate properly, and also must be running to be put into low power mode.
