it is a well accepted fact, that if you are within a relatively weak network coverage, the phone (not just the iPhone) has to "work harder" to amplify the signal.

it is a phone afterall, and doing what it was designed for, in the first place.

however there is a tip (conducted by myself and hence has no whatever scientific results to back me up) is to turn off the 3G toggle perpetually.

twittering, chatting, e-mailing in general, work pretty decently with EDGE (and even GPRS). only when i need to use safari, the 3G comes up.

you will be surprised at the power conservation with this simple maneuver. however, if you procrastinate about being troublesome et cetera, then there is nothing much that can be done i suppose...

It IS possible. Its like having to shout louder to someone far away as oppose to talking to someone just beside you. It is a very logical theory.

I guess. But it still doesn't help a lot in battery saving.

P.S. I'm getting way too much fingerprints and markings on my screen. The new protective screen doesn't seem to last long. Anyone has the same issue?

if 3gs....they have improve screen with a new coating. but it doesnt mean tak kotor with fingerprint at all....but less fingerprint and marking on the screen. also easy to clean with a single wipe. u can use anti glare screen protector for less fingerprint....

my i3gs normally can last around 1-2 days. I play it quite heavily and charge everynight through usb port.

Anyway, after turning on push feature due to playing some online game, mafia wars, vampire live, kingdoms and so on, I turned on the push notifications without knowing the adverse effects. True enough, the battery drain started. The phone's power went totally drained and was hot even without turning it in off mode.

100% to 20% only lasted around few hours.

After doing some reading, I have turned off location finder and push. Hope that batt life will go back to normal.

I heard about this also from a friend. But do you know for a fact or you just guess? Because there is no indication about this in the manual. Just curious.

Yup me too. Only switch on 3G for browsing on safari or youtube. Only switch on wifi for downloading updates.

I turn Location Services On, Push, and 3G on. My battery can last me for at least 1.5 days. It used to suck, but changing the carrier solved it for me.

Anyway, you can leave the iPhone charged for as long as 1-4 days. The battery doesn't overcharge. This is why all the speakers for iPods and iPhones provide charging capability, so they can sit there for a long time.

Seems like theres no real solution on the battery issue and overheating issue on 3.0 FW. Ridiculously going down 1% for 5minutes (overheating)
Finger crossed before my phone going kaploded, im going back to 2.2.1.

First gen user here.

just waiting for os 3.1..hope this issue fixed.

im using FW 3.0.1 right now. running smoothly

no battery drain issue? how long ur battery can last?

5 days is impossible on my 3G S.

Seriously,
your phone won't even last for a day, if you

- make calls
- SMS
- email
- iPod (1 hour)
- Safari (1 hour)
- read news (NY times, AP mobile, ESPN, Eurosport)
- play games for a while (Bejeweled, Pinball, TTR 2)
- Facebook, Twitter, FML
- Dictionary

I end up with my phone having around 20% every evening.
The same thing happens on my friend's 3GS as well.

He probably doesn't use his phone as heavily as us which explains the long standby time versus usage time.

Anyhow, I wonder why would ppl always wait till their battery is flat before charging? It wastes a cycle of the battery life.

Because I don't bring my charger out? Hmm...

Anyway I heard that there's a charger-like mini-device for iPhone/iTouch
where you can use its battery when you connect it to your iPhone

lolz. i was charge my iphone twice in 1 day. use a lot for sms'ing email'ing

sorry for off topic, anyone use after market car charger for iphone?? izzit recommend to use? or any brand is good to use?? thanks.

it's never a waste of cycle. if say u r a heavy user, and u have used ur phone till its battery shows 50% and u charge it till 100% and again u use it till it shows 50% and u charge another time to 100%. this is equivalent to using the phone till it goes flat and charge it till 100%. both are considered as one cycle. i believe it's explained in the iphone online manual.

Exactly.
Assume a person uses merely 30% of his iPhone's battery everyday.
He will need to charge like thrice to complete one cycle.
That is, 3 days?

Also, the manual stated that the battery life will fall to 80% after 300/500 charge cycles (If not mistaken)
So if a person consistently uses 1 charge cycle everyday,
His battery will start deteriorating after hmm, a year or two?

Its time for an iPhone 3G SS then. LOL.

Thats exactly what I meant what. But so many people are waiting till its empty before charging. It would waste a cycle cos they get the chance to charge but they dont
