Thats strange! They should comply with the specs and be @ 158 g .
I did unintentionally manage to make my 820 a little lighter by buying a battery off ebay, it looked the same as original and worked ok ,but was very light and upon close inspection i could detect a joint under the plastic skin, it was really a smaller battery 1/2 size that had a plastic adaptor added to increase its size ,worked ok but verymuch doubt its capacity was anything like a original one.

Yeah exactly.. 158g is 158g, however, maybe its like your old 820. Could be different battery, it would be nice to think so, because i do know some people have been having some serious battery issues, so maybe Nokia made some revisions.. My hardware revision is : 4.4.0.2
