Ive been wondering about battery capacity over time. I already know that after a couple years, a phone thats in use may lose somewhere near 20% of its capacity (give or take depending on usage) I also know that external charger packs tend to charge around 70 to 80% of their rated capacity. I also know that when storing a lithium battery you shouldnt store it full or dead...but around half charged...and that this is how batteries are shipped inside phones or as standalone products.

What I dont know however, is what kind of degradation or loss of capacity to expect in the battery of a new unused phone, that was old stock from a some time ago. Be it 1, 2, 3 years or more. For example...say someone buys a phone that released in 2013...it was manufactured in June of that year and has a 2000 mah battery.

Aware me oh great bros of xda. Ive been curious about this for some time.
