Battery Issues with 3.0.1

Since 3.0.1 - I noticed battery life plummeting... thought it was a fluke at first. Today - had a full charge at 2pm. It's 9 now and my battery is at 10%. No phone calls, no messages sent. only 3 emails received on phone. No new apps since upgrading. Something is very wrong.

Used to go for a full day of active use and still have half a battery, maybe a little less than half.

Also noticed phone is almost always warm or very warm to the touch. the new deal did something...

It is not 3.0.1 per se; it is the update process that caused your problem. There are a couple of things you can do to fix it. The first is if you have a MobileMe or Exchange account that uses push email delete the account, reboot and add it back. If this doesn't fix it (or does not apply to you) connect to iTunes and do a restore as a new phone (don't reload the backup, which probably has data corruption in it). Then add your email accounts and apps back. Note that you will lose any local data in the apps, such as high scores for games, and you will have to re-enter passwords.

Experienced same since 3.0.1 upgrade. Your suggestions worked. thanks

The bug isn't in the update process, it is due to corrupt data in the saved backup. As you normally never restore the backup except in the event of a restore of the phone corrupt data can persist there for months. Then when you finally restore it things don't work right. Restoring as a new phone avoids this.

I've had the phone for a month and, while the battery life if active on the net at 3G isn't great, it wasn't that bad.

I started noticing the same exact problem. I didn't think about the update causing it, but that's the only thing that I've changed. I've been going through a 100% to 10% within a half a day at work and using the phone exactly the same as before. The battery never dropped this fast before the upgrade.

I'm glad to see it's not just me, this problem definitely started after the upgrade. My wife has the identical phone, (we bought them at the same time) and we haven't updated her to 3.0.1 yet, and her's is acting normally. Mine is not.

I'm technically savvy but a iPhone noob. So, If I restore the software "as a new phone" will I lose all my contacts and calendar entries? I'm saving all contacts and calendar entries on the phone, not syncing them with anything.

If you sync as a new phone you WILL LOSE your contacts and calendar entries. As you will if the phone ever crashes and has to be restored. The iPhone is not intended to be a standalone device; it MUST be synced with a desktop calendar and contact list to avoid data loss.

Thanks Finch,

That's pretty much what I expected. I tried the MobileMe trial and wasn't happy with it. For the price, no thanks.

I've tried to sync with Google Contacts, but it brought in a bunch of crazy contacts from people, that I've only, maybe emailed once, or was on I list I replied to.

My question to all you iPhone techies.... is this.......

What is the most reliable, Windoze based, iPhone contact/date book backup that will backup my phone's contacts and date book?

One that can be restored easily Without creating field major discrepancies that will need to be hand fixed afterward??

Syncing with Google seems to mess up the work/personal email contacts, and imports every person I've ever replied to using Gmail... that blows

Short of using MobileMe, is there any easy way to backup my contacts that will be easily restored? Or calendar?

My attempts to Back up and restore to Windows Address book was not so seamless, and created a bunch of dupes and/or inaccurate fields in existing contacts that were FINE before???? ...

Is there ANY windoze based backup/restore that would allow me to organize all categories (contacts and dates) with out messing up the entire contact DB??

Apple sure doesn't seem to make it EZ for windoze losers!!

Any tips from iPhone/windoze admin/power users welcome!!

I use office outlook 2007 works fine for me for contacts, I prefer google calendar for calendar entries (as you can have multiple calendar for each memeber of the family), I use Nueva Sync to get the calendars synced to the iPhone

as for the battery problem I was suggested to perform a Hard Reset and also let the phone run dead then charge fully (to recalibrate the battery meter) up to now this seems to work for me

I initially used Outlook 2003, which maps both calendar and contacts very well -- that is, all Outlook fields appear on the iPhone, but iPhone has some fields that don't map to Outlook. When ActiveSync support came out I switched to it, so I no longer need to sync for updates.

Hello everyone!

I just bought an iPhone 3GS a week ago and I'm not impressed with the battery. My 2G iPhone was great and would last 1.5-2 days plus 6h use... My 3GS 3h use max + 12h standby = 10% charge left! I won't get more! I do quite a bit of SMS during the day and some internet in the morning... but by the afternoon my phone is lower than 50%. Bluetooth off, GPS off (MobileMe on push) I restored my phone "as a new phone" following the advice on some blogs but it did not change anything. I cannot say whether it was the update or not because I got my phone post-update. Should I take it back to the store? Is this just as good as it gets for the 3GS or is this not normal?

Add me to the list of people who updated and lost massive amounts of battery life. My phone almost dropped to 0% battery life while on standby when I slept last night.
I'm also one of those people who never got Outlook to sync correctly so I'm not crazy about trying to manually add lost information. Also, it seems that data stored with apps might be lost too. There has to be a better way.

I reset my iPhone and took it to the gym. 2h19m later, it's almost dead with only music usage, push notifications off, bluetooth off, wifi off. I really don't want to wipe it and restore it because I'll lose a lot of info... Decisions, decisions...

I too have noticed a big fall off in battery performance from my 3GS compared to the 1st gen iPhone I had prior to upgrading...

Just played one game of Flight Control (Score 175), and 6% of battery got used up ! Hope Software 3.1 fixes the battery issue... might also try a restore on my laptop this evening...

Forget about a restore. How can the 3.0.1 firmware update be removed, returning the device to the 3.0.0 platform?
