hi, all
I bought two of these "smart" batteries a couple days ago from this website http://www.batteryselling.com/compaq-evo-n610c-battery-8-cell-5200mah-14...
due to the good prices and longer warranty. Now i tried to use the the smart mode in the battery manager according to what the customer service have noticed me. 

well, the thing is, there are some options coming to me to control when "data" is turned off. Does it mean i should disable 3G, WiFi or both of them? But i think this practise is dangerous since it's probably resulting in push e-mail or other background data being out of updating after the 15min timeout period,. In other word, most of my data connections will be closed and i can't get e-mails in this mode.Does anyone has any issues with the data on smart mode, including timeout and others. Discuss any thoughts here, welcome!!

what will be the correct way to use this mode to get more battery life?
