do you have any lag or freezes on your 820 ?

[stalemate1]

If yes then how often do you experience it ?

 

[Ashish Saraf1]

Never lagged !!

i have been using HD7, 520 and 820..none of them ever gave me a problem

820 has the best battery !!
gives around 2 days with moderate to heavy use

no lags here since 8 months

My wife has never complained about her 820 and I didn't experience any while I was its owner.
