Original iPhone 3.0 upgrade - No battery life and running warm to hot

As with you I have upgraded my original iPhone with the 3.0 software and immediately began seeing problems with the battery life as well as the Mail program. Shortly after selecting Mail the program would crash and battery life was cut in half. Well, after spending much time at the Genius Bar today we discovered the problem with the phones battery and Mail program. Deleting all my mail accounts and then re-entering them supposedly resets the accounts to better work with the new 3.0 software. (Not sure why). The short battery life and heat being generated by the phone are all on account to the mail accounts continuously trying to connect to the server. As a note the accounts that affected the software were accounts other then my .MAC account. Good Luck

I would say leave it open for now. For me, Push and Location services were off before and after the upgrade. After the upgrade if I charged my phone in the evening, the battery was almost dead by morning - just sitting on the counter doing nothing.

The only thing that is saving my battery life right now is to turn WiFi off.

I just wanted to weigh in to say that I upgraded my original iphone to OS 3.0 last night. I did it with some trepidation after reading this and other threads. But the installation went fine. (I have always had all push notification turned off and only one Gmail account active on the phone.) My battery life is unchanged. My phone remains cool to the touch. And I have to say that I am pleasantly surprised by the performance of the new OS. I thought it would run slowly on the original iPhone but it is actually speedier. Cut & Paste, search, and being able to forward text messages are three big pluses for me.
After I upgraded my 2G phone, I also upgraded my wife's 3G and my son's 3G. Those also went smoothly.
So my sympathies go out to those who have had troubles with the upgrade but I don't think it is a systemic problem.

This worked for the two 2G iphones and the 3G iPhone following upgrading to version 3.0 from 2.2;

1. Go to Settings app on the iPhone > General > Scroll down to "Reset" and the select the top option to "Reset All Settings" This will reset the settings and reboot.

2. Go to Settings app on the iPhone > General > Scroll down to "Reset" and the select the 3rd option to "Reset Network Settings" This will reset the settings and reboot.

3. Now plug the iphone and connect to iTunes and click on the "Info" Tab

4. Manually check the synchronisation settings as they may need to be reset to how you want them to work - just act like you are starting from scratch. (contacts, music, etc.)

Problem solved !!

Obviously turn off Fetch, Push, Wifi, 3G etc if not required to maximise battery life.

Reseting everything like petersholton described didn't work on my 2G.
As soon as I turn on PUSH, it gets hot again and battery starts draining.

I have one mobileme account and two imaps running.
also tried deleting the imap accounts, but it didn't help.

what bothers me most, is that the new feature "where is my iPhone" only works with PUSH activated!

Quick note - my husband and I were both having this problem with our original iPhones. We turned off all services - push, location, wifi, bluetooth, you name it - nothing worked. Battery life was at maximum one day, even on standby. Overnight, it would drain over 20%.

Finally, my husband read on another forum to completely restore your iPhone, then _set it up as a new phone_. You will lose some of your settings and your icons will get scattered, but this has totally fixed the problem for both of us. Overnight, battery drain is 1-2%. I have gone back to only having to plug in every 3 days. Right now, I'm at 24 hours combined standby and usage and still have 50% battery left.

Give this a try - setting it up as a new phone, NOT restoring an old backup. You will still get your data and apps, but might have to re-do some settings. To get the battery life back, it's worth it!

I managed to repair my battery problem by doing the whole restore & setting up as a new phone process but it's still a little odd.

My battery meter won't go higher than 89% for some reason :P. I can leave a full charge overnight and it Won't get higher. Once it reaches 89% it like stops the charging process. pretty odd.

Whoaoaoa.
So I restored my iPhone 2g to factory settings, set it up as a new phone & added APN username & password (I thought that might be the problem)

So I did all of that and it did the trick BUT I just got a call from my service provider telling me I went over my limit for the month because of Internet Use!!!!! I figured hey that might be because I configured APN settings so I deleted them & battery problems started coming up AGAIN!!!!!



HOW DO I DISABLE EDGE?!!!!! It's costing me a fortune and killing my battery.

has anyone from apple figured out a legit cause?

As a side note this 3.0 upgrade heating up + battery life has also happened to my friend with an iPod Touch 2G.

Apples measures are extreme and really don't make much sense! They are willing to exchange his iPod for a new one until he gets one that doesn't have any issues such as this!

I noticed the problem with the update immediately, although with my 2G it was only battery drain. The thing that worked straight away was turning off Push - battery has been fine ever since.

Gonna update to 3.0.1 to see if this has solved the problem - anyone else updated and researched this yet?

Thanks.

Sooo...

I solved my problem to a certain extent.
What I wanted to do is disable all data (Edge and 3G) on the 3GS with 3.0, not jailbroken but factory unlocked.
Using the Fake APN Profile unfortunately caused extreme battery drain, as also pointed out here:
http://thebigboss.org/2009/07/27/how-to-disable-edge-maybe-on-30/

This problem can be solved by doing the following:

1) This step is optional but you can check exactly what is going on in your phone by doing it. Download and install iPhone configuration utility from Apple.
Connect your iPhone. In the Console you can follow what is happening.
The massive battery drain is caused by the constant attempts to connect to network, when the Fake APN is installed.

It looks like this:
Sat Aug 15 16:17:56 unknown CommCenter[28] <Notice>: Error (58) activating PDP context 0 that supports types 0: kGprsMissingorUnknownAPN
Sat Aug 15 16:17:56 unknown CommCenter[28] <Notice>: Telling PDP context 0 to go active.
Sat Aug 15 16:17:56 unknown CommCenter[28] <Notice>: connection mask for 0 is 0

This will occur all the time. After you completed the following 4 steps, these entries should be gone.

2) On your iPhone, remove the Fake APN profile.

3) Then disable Push and Notifications

4) Restart your phone

5) Re-install the profile

6) Your battery drain should be gone while data is disabled at the same time.

I know the problem with this is push and notifications will be gone on WiFi as well.
Currently I don't see a solution, however, the bigger problem I could see from my testing is not push but notifications. So if you do have WiFi most of the time, then leave push on, its impact on battery life is less with regards to this problem.

Unlike notifications, it only shows up with errors in the console 2 times or so a minute.
Notifications shows up every second or so.


I really hope this helps, I am still in the process of testing the exact impacts of fetch, push etc
but maybe someone has more input.

Let me know how it goes.

3.0.1 did NOT fix my heat issue.
WIFI is off
Push is off
Tons of APPS have been removed - not fixed
Phone has been restored
New Sim card installed
Location is off
Notifications are off
I have more details on this other thread, as I have a first gen iPhone. My friend, who's phone is only 6 months old, is also experiencing this problem.

Here is the thread:

3.0.1 was just a security fix.

Do you have an original APN / Carrier file running on your iphone?

I imagine I have the original APN/ Carrier file, unless when Apple had me restore and reset several times, it changed something? I see your instructions above and I guess we may try that next. Right now, nothing really seems to be a fix for this "iDrain" that has been aptly named. We are all just grasping in hopes of fixing this.

It would be great if Apple would just publicly acknowledge this issue and make a statement as to them being aware and working on a fix. It would save so many of us headaches in trying to figure this mess out. Instead of them telling me I qualify to upgrade and buy a new iPhone - like that makes me feel so much more confident when the new ones are going through this too. I already spent $500 on this thing. My husband's is perfectly normal and is the same age phone. Our APPS match, except I removed all APPS I had over the past 1 1/2 years. And, whereas my settings are all off, his are on and running fine and he has 6 screens of APPS - I have just under 2 now.

The only difference I can mention is that I grabbed the 3.0 when it first launched. I had a nightmare of a time with the update. It locked up my phone and Apple had to walk me through resetting it. They told me that issue happened with 2.0 and it wasn't suppose to with 3.0, but it did - at least that first day. After 3.5 hours of "fixing" this issue, my phone finally started working normal - for about 2 weeks.

andersonincyprus - 3.0.1 was a texting security update, as Florian.K. mentioned. It didn't correct this heat issue. But you should get that update anyway.
