DigitalSmoker Posted September 16, 2018 Report Share Posted September 16, 2018 (edited) What is going on with this battery? Plug it in to charge and check device manager, battery never stays at 100%. It goes up to 100% then drops to 97% then up to 99% then down to 93% then back to 98%. Is anyone else seeing this as a issue? Here is a pic of device manager, 97%?

retird Posted September 16, 2018 Report Share Posted September 16, 2018 I read this a while back...... " The hysteresis band of the charger chip is 4.1 to 4.2 volts. That is, left to it's own devices, the charger will charge to 4.2, then let the device discharge to 4.1, then charge back to 4.2 in a slow cycle.If it is left to it's own devices. If charging is interrupted for some reason (firing, USB command to stop charging, whatever) and it is above 4.1 volts, it basically says "eh, good enough" and doesn't charge farther. That's half of it. The other half of it is on this chip, the total accuracy of the battery monitoring in he processor is +-2% worst case. Typical is about +-1% 1% of 4.2 volts is .042 volts. So it could actually be charged to 4.2 volts and be reading 4.158.That doesn't hurt anything because unlike the 200 class devices, the charger here is standalone, so the processor's battery voltage monitoring accuracy isn't a safety issue." 1 1 Link to comment Share on other sites More sharing options...
Droopydroors Posted September 17, 2018 Report Share Posted September 17, 2018 I have to check this on device manager as well. I let mine charge overnight and when I woke up to leave for work the LED was out. I believe I read this is normal because the device shuts off the USB after an hour of non use. But the battery definatley was not charged fully because it only lasted an hour or so. Link to comment Share on other sites More sharing options...
dwcraig1 Posted September 17, 2018 Report Share Posted September 17, 2018 Check Device Monitor when fully charged, you should expect to see voltage around 4.13 - 4.14 volts area. Link to comment Share on other sites More sharing options...
Vape_Like_A_Boss Posted September 17, 2018 Report Share Posted September 17, 2018 (edited) If it's doing what is discussed in the first post and this other post that was a quote from around the forum, then it's working pretty much the way that Android kernels control charging in an android powered smartphone, at least in HTC models that I'm most familiar with. They charge to 100% and then bring the power back down to 97 to 98% and rotate a trickle charge from that point. It's allows for better longterm conditioning of the battery than charging to 100 and holding the power there, because that would zap the lithium batteries much faster.

sgmartin Posted March 18, 2019 Report Share Posted March 18, 2019 I have the same problem... how i can solve? Link to comment Share on other sites More sharing options...
DigitalSmoker Posted March 18, 2019 Author Report Share Posted March 18, 2019 From other posts it's working correctly and is the norm for a DNA GO chip Link to comment Share on other sites More sharing options...
