@All,

Good news, this issue has a short term fix while we wait for the next release of deviceOS.

I added this line to the header:

```auto
PMIC pmic;

```

Then, this line to the Setup() section:

```auto
pmic.enableBuck();

```

The credit for this fix (and explanation of why it works) is from @ielec in this post:

This post by @avtolstoy might be a good starting point for you: [Edit] - This may not help in your case, but for Solar Recharged Boron’s I use the USB connector for the input source. I get the same results as you when using Vin(Vusb) pin, but charging will resume during/after an EN Pin Shutdown when using the USB connector. I have no idea why man_facepalming

As always @Rftop provides great perspective. I wanted to repost this fix on this thread so it would be closed. I have deployed this fix and it has worked very well.

@Rftop the excessive energy drain was finally tracked down to an issue with Particle's providers in Rwanda. We were seeing round-trip times of up to 5000mSec and the devices would hang while attempting to connect and authenticate.

Thanks,

Chip
