iPhone power drain, part 3: Conclusion
In late January, I was playing around with an activated sim, on AT&T.
No unlocking required.
Jailbreaking is always fine, though.
I intended to run it in my iPhone 4, but wanted to see it work in the iPhone 3GS first.
Why? Well, I would have to cut down the sim to fit the iPhone 4.
And even though I had a tray to restore it to a full size sim, that wasn't a very workable solution.
So, cutting was a one-way street.
The 3GS wasn't taking to the new sim.
It worked in a Nokia and my Motorola Razr, but no love in the iPhone.
In the many months of study, I learned about a number of things that could trip me up.
So, I knew I had to start fresh for the best chance of working.
* Bright Idea: *
What about rolling back the iOS to an older version to see if my power drain was related to 5.0.1 ?
In the mean time, Sn0wBreeze had been updated to v2.9.1.
It claimed to handle a bunch of old versions of iOS!
Wow, this might be just what I need.
I built a copy of iOS 4.3, keeping my ugly iPad 6.15 baseband.
That first night, I got nowhere.
Next night, I defected to RedSn0w to see what it would do.
Well, it didn't actually support my 4.3 at all!
So, I went back to Sn0wBreeze and tried again.
The author is iH8sn0w, and he has a suite of tools you'll want.
With the use of TinyUmbrella, iReb, and iTunes, I finally got a jailbroken iOS 4.3 onto the 3GS !
... and iTunes auto-activated the phone with my new sim installed!
(if you don't know what that means, trust me, it's wonderful!)
The phone came alive, and immediately received an SMS message.
Just spam to the previous holder of my new number, but a GOOD sign!
So, what ever happend to the battery life?
Well I just completed the first overnight run.
12 hours to the 98% point, and it turns out I'd forgotten to put it into Airplane mode.
Not much point running the test again.
This was already wonderful!
Now, was it a combination of the iPad baseband 6.15 and iOS 5.0.1?
I can't really test that.
But, you can #$^& well bet I won't be putting 5.0.1 on my iPhone 4 any time soon!
... feedback requested from iPhone 3GS users running iOS 5.0.1 and NOT baseband 6.15 ! ...
