There is no reason why you should not. Here are my settings for my iphone 4 if you care to try them:

I use cell data in the field and turn WiFi off.
I have the following in my notification center:
Mail (3 mail accounts set to get mail every hour)
Location is on for:
MotionX GPS Drive
Find My Iphone
System Services are all turned off except cell network search. I sometimes turn them all off.
Bluetooth off unless I need it.
Ping is off in Restrictions
iCloud set to back up to back up Contacts, Calenders and Bookmarks.
When I installed 5.0.1 I did it OTA. But I redid it once I plugged my iphone to Sync with iTunes. Somehow, iTunes decided to download and redo the 5.0.1. I have on idea how this happened.
I do a RESET ALL SETTINGS every now and then. Not a Restore, just a RESET. You will have to redo your settings, but it is very easy to do once you get the hang of it.
I let the battery drain down below 20% almost everytime I use it. I drain it till the phone shuts down on occasion.
When I charge the phone, I let it charge til the battery icon becomes a plug and then leave it on the charger for 15-20 minutes. I take the phone off the charger and let it drain to about 95%, then charge it back up again like before.
I have Battery Doctor so when I wake up at night I look at the phone and if it is fully charged I unplug it and leave it in airplane mode til I wake up in the morning.
That is pretty much it.
