Native email questio

[jskinvest]

I deleted my Yahoo mail and Hotmail apps thinking that it might save battery life. I added the two accounts to the native email app and did the auto configuration which has push email. So far I hardly receive anything via push.

I then set up the same yahoo mail account manually with 5 minute fetch intervals and that worked fine.....5 minute poling.

So my question is should I just delete the push configurations and stick with 5 minute poling? Also, which drains the battery faster...push or automatic 5 minute poling?

Or should I just re-install the yahoo and Hotmail apps? They worked fine as stand alones but my concern was possible battery drain.

Thanks
