New HP Envy Battery discharges when unplugged

[Huffer]

Then what would you like the answer to be? A brief check of forums for Dell, Lenovo, Acer, etc. shows this to be a very common issue and it all started when batteries went from external clip in type to internal and asked to do the work that used to be done by a CMOS battery. So experiences with laptops more than about 5 years ago were very different.

Hey Texsinbad.

 I also have an "Army" story I'd like to share with you. My dad is a Navy officer, and when he was very young and had a problem with his car's steering wheel (it was squeaky), he asked the ship's chief engineer for advice. The answer was that ...."Well, that's no problem, no problem at all. We'll just take a Black and Decker Power Drill, make a hole in the steering wheel's cover and pour some oil inside. It'll be fine!" I think that the moral of these two stories is that you can do way better than listening to a mechanic in the military.

 About the battery discharging when unplugged, Huffer EXPERT Level 18 is just saying what everyone knows. I'm not sure about the 5 years ago though. I think that laptops made in the 1990s and around the turn of the millennium might have had a 0% percent discharge. The same is true about cars of (up to) that period. Their batteries remained charged for a long time, and lasted for close to a decade. Cars nowadays (and I'm not talking about hybrids or EVs) lose a lot of charge, because many (electronic) components need the juice, even when the car is parked and doing nothing.... Well, guess what -same is true for today's laptops. All the laptops I have, including a 2014 Probook 650 G1 with a removable battery, get a daily discharge of 1-2%. I do have an Acer Travelmate (2015 model) that I use as  a backup myself, and I leave it unplugged for a long time. Never booted to anything but a 100%Charge. BUT, and this is a but with two Ts in the end, if I leave it unplugged for a couple of months and then try to boot with its battery, it only lasts 5minutes. If freshly charged, the battery lasts 10 and a half hours. So that means that the Acer is actually discharging like all other laptops, but the battery charge status isn't registering correctly. And that's exactly what you're seeing on your recent ENVY laptop, a higher precision Coulomb Counting Algorithm.
