reported Battery charge level Issues - Replacement Batter

I have a Samsung Notebook NP700Z5B-s01UB. Samsung recently put in a replacement battery. Since then the battery icon charge reported will start at 100%. then each day it will decrease 1%. Every day it also says for example today 98% available (plugged in, not charging). According to the Samsung SW Update, all of the drivers are current. I can unplug, drain the battery. It will then charge up to 100%. I leave it plugged in and the next day it says 99% available (plugged in, not charging), leaving it plugged in the next day it says 98% and on and on. I really do not want to send it into Samsung for a lot of reasons so I am hoping someone can help me.

 

I have about the same behavior with my NP700G7C. It probably is when under charge the batteries get a top charge. This is where they get that extra little bit of juice at the end of a charge. This is known with all Lithium batteries to have some bleed off. Mine tends to settle at 98% or so, occasionally the charger picks up and charges back up to 100%.

This is why they have the 80% battery saver. It keeps the battery off 100% and a top charge extending the battery life. Most Lithium batteries will take the 80% with no real issue, it is that extra 20% that is forced in and why it can take almost as long to add that last 20% as the first 80% capacity in some chemistries.

 

What you are seeing is normal. Once the battery is charged and the computer is left plugged in then there is a slow natural discharge but the computer won't do a top-up charge until the charge level drops by several per cent. This stops the computer in a notebook normally run on mains power from being killed by frequent top-ups.

However, as noted above, if your notebook has the battery life extender option then enable it unless you need to use the full amount of battery capacity for a long day away from a power outlet.

Thanks John and TanWare .... appreciate the overview. Unfortunately, I do not see this as "natural" and here is why:
1) The original battery never had any of this .... would charge, stay charged etc. A replacement battery was installed as a mistake via The Geek Squad which I only realized after the fact.
2) I can leave the power cord plugged into the laptop and each day the power register shows a charge 1% less than the day before. the longest I let it run was 22 days when the power register showed 78% not charging.
3) I can drain the battery and recharge to 100% however if it is un-plugged and then re-plugged in without turning on the laptop, the power register shows the % charged before unplugging and then each day it decreases by 1%.
I have looked for this "power saver" setting to see if it is set to on ... but to no avail.
I have asked Geek Squad and Samsung - both say there may be an issue with mother board ... however given their history in making repairs to have things work right I am very reluctant to let them at my laptop again.
