Lovin the iPhone4 Battery!

Bluetooth. WiFi. Push. All get 'confused' when moving to new hardware.

Any particular reason why?

Do you mean when you hook up the phone for the first time that you should set it up as a new phone? Why can't you just restore from our most recent back up?

I feel like my battery is still getting drained pretty quick. I think like a 30 minutes Facetime call drained my battery 20% or so.

"Thanks for the suggestions in this thread. They fixed my problem.

I had used the backup off my 3GS and with Bluetooth, Wi-fi, Location and Push on with the brightness on auto between 40-50%, I was losing about 1% off the battery every 1-2 minutes when surfing the web. I went to sleep last night and woke up and the phone went from a full charge to 50%. I was thinking those reviewers with their "300 hours on standby" and "24 hours and it never went in the red" were smoking something

I just did a complete OS restore and had iTunes see it as a new phone. Battery no longer has a ridiculous drain."

Wouldn't doing this kill all of my saved games, i.e. GTA and Angry Birds?

Precisely. Major downside for gamers that Apple must fix.
 
I'm down to 60 percent with 2 hours of usage. Ive talked for about 20 mins and the rest have been facebook and web surfing. I restored from a backup of my 3gs. Won't I lose all my contacts and photos if I set it up as a new phone? That doesn't really seem right. What difference does that make anyways?
 
Of COURSE the iPhone 4 has good battery. It doesn't need to send a cell-network signal most of the time when you're holding it, so it saves battery that way. :D

I keed I keed... I'm definitely impressed with it over my 3GS's battery.
 
I used a backup from my 2G when I first got my iPhone 4.

Could somebody explain the setting it up as a new phone thing?

Won't that cause you to lose all contacts, etc?

They will be removed from your iPhone. So will game settings and SMS.

I have contacts, calendars, bookmarks synced to MobileMe and Mac OS applications.

If you are asking you probably have never dumped these items onto your desktop.

It's a lot of work the first time.

Could I do the MobileMe free trial, then sync, then restore, then drop the MobileMe?
 
I was planning on restoring from the backup of my iPod Touch (I'm waiting for white and this will be my first iPhone, coming from Verizon), but now you guys have me worried about it affecting battery life :( I really don't want to start from scratch on all my games etc, why can't they come up with a better way??
 
I restored from back up and I get pretty good battery life but not as good as these guys are claiming
 
I definetely agree. I have Push off, Bluetooth off, brightness set to around half, 3G on, and the battery drains extremely slow... I havn't done any scientific comparisons, but it is much better than my 3GS. Easily lasts me through the day with pretty heavy usage..

At night, I turn 3G off (WiFi On) and I lose at most a couple percent over the night.

Setting up as a new phone definitely works.
 
I have been using Google's exchange server for my contacts and calendar and now notes (free) and never have to worry about losing that info on a clean install. I just plug in the server info and BANG it all back in. It's a process to get it all set up but easy to do on the computer.
 
I'm sorry but anybody who is trying to claim their battery life is being "confused" by using a backup is completley misinformed and has no idea what they're talking about.
 
My battery life is awful!!
So if Im restoring from NEW, how do I save all my SMS and photos etc or is this not going to happen?
 
Both mine and my wife's battery usage is horrible. It's just fine and dandy in standby mode, but as soon as we start using any apps it just starts draining like a faucet. Just this morning I checked Twitter and Facebook, took a total of maybe 2 minutes and it went from 96% to 92%, in just two minutes.

I was using MobiTV and in 10 minutes it drained 21%. This is totally unacceptable for me. My 3GS kills my 4 in battery life.
 
I restored from backup and my battery has been fanatstic so far.

I'm on 62% battery and it#s been 1 day and 3 hours since my last full charge :D

My 3GS would have been dead after about 10 - 12 hours.
 
Using the phone in the same way I used my 3GS (push on for several apps, IMAP e-mail/calendar checking every 30min., 3G on all the time, Wi-Fi connected for roughly 2/3 of the day, etc.), I'm getting at least 25% better battery life, if not more.
 
LOL, I'm on hold with an Apple Tech Rep right now while she gets her supervisor. She told me losing 5% of battery life in 2 minutes worth of usage is normal and that the iPhone 4 does not have as good battery life as the 3G or 3GS. I told her that goes against what Apple is advertising and Steve Jobs said during the keynote.

Well she just came back and told me to turn off push, location services, GPS... anything that uses any background stuff. I asked her why when my 3GS had no problems like this and she just reiterated that the iPhone 4's battery is not as good as the 3GS's. Needless to say, I'm massively disappointed with Apple right now.

Well as an update... the girl said that Apple is going to send me a new phone and take this one back. Still disappointed this has happened, but happy that they're doing something about it.
 
I restored and set phone up as new. Prior to that i restored from backup

Battery life has improved but nowhere near as people are reporting on here or like my 3gs.

Two nights back to back I have charged 100% and gone to bed only to wake up and see the battery down to either 80% or 81%

I only have one notification turned on and thats for Hullomail, Push is off and set to fetch every 15 mins and 3g is always turned off, wifi is also on.

Not sure where this 20% is going to overnight.
 
I restored from a backup. Battery life is not much better my than 3GS, nothing too tangible. Maybe I'm spoiled by the iPad's battery.

Anyway, it's almost as if the iPhone 4 thinks it has my 3GS's battery instead of a new superduper "long life" one.

There's NO WAY I'm going to restart from scratch - I've got too many apps with configurations and SMS etc...

We can only hope that there is a simple firmware fix.

Juventuz: let us know how your battery life is with the replacement. Maybe we have a dud batch...
 
I wasn't getting very good battery life at first, after charging pulling it off the charger in the morning around 11 am I would be at 25 percent by midnight.

Just turned off push notifications, however, and after using wifi with Safari for over a half an hour and being on standby for over an hour, I was still showing 100% battery.

Unfortunately I typed too soon, but it was more of me misunderstanding than anything. Apparently they're not going to send new phones, rather just a box for repairs so I have to send my phone out to them to repair. She said it'll take 7-10 business days. Being that my wife and I use our cell phones as the house phones as well I told her that it's completely unacceptable. She said that's all she could do. To say I'm pissed is an understatement. Maybe I'll take the hour drive up to Syracuse to the Apple store up there to see what they can do.
 
It's great, using tomtom, ebay app, surfing on and off, bluetooth and wireless on and still had 50% at end of the day.:)
 
To save your photos (these instructions are for windows users, not sure about macs), go to explorer, click on the iphone (logo is of a digital camera) and after clicking through the folders, you should see all of your pictures. Copy them to somewhere on your computer and sync them back when setting up your iphone.

For contacts, you can sync them with either outlook or windows contacts and then sync them right back on the new phone (make sure to click merge contacts!). I just use google sync so you never lose the contacts. Instructions on uploading all your contacts to google : http://www.google.com/support/mobile/bin/answer.py?hl=en&answer=138744
Adding the sync option on your phone: http://www.google.com/support/mobile/bin/answer.py?answer=138740&topic=14252 .

To set up your iphone as new, restore your iphone and click set up as new phone and don't restore from any backups. You will lose all your saved games though. Hope this helps :)
