I would really like to fix this, 'cause the battery life is really terrible. My friend charges his phone every 3-4 days, whereas I charge it every 16 hours.

I feel it's really bad for the battery itself.

Hey everyone,

someone had mentioned in this thread that imapidle might work which you can get from the installer. It worked on my phone with sacrificed battery life. I tried all the other fixes too and they seem to give comparable life times. Just a note the johnstool was very unstable worked sometimes and not other times.

I have also seen a lot of post where people in France are experiencing similar problems and they said that apple tech support said that it would be fixed via software upgrade. I will believe it when I see it.

I don't undetstand. This thread occured since September, but 3-4 months left, no one can really solve this problem (just to avoid).

I am willing to donate for the software that can help me (really) solving this problem

:-(

Hey guys, I remember reading about the solution to this problem. From what I can remember the problem was a hardware problem. Something about the antennae connection to the commboard. Sorry I can't be of further help but if you look around page 5? of this thread someone fixed it by replacing the Comm board but I do not think you need to go this far, but you should definitly check the antennae connections.

I wish I could be of more help, but like I said, I remember on a forum somewhere that someone mentioned it had something to do with their antennae....

Befoer you go checking this though (it's a long hard route) google for the solution and see if you find what I did...

Good luck guys!

Hi everybody.

I came up to this thread after searching for ages.
The orcinus fix is working for me as well but it is eating up battery power like hell.

So I tried messing with the numbers in the .plist file but as you already noticed it is not doing any good. But I tried something else - I edited the file and deleted some parts of it and now it is working without deleting the .plist or renaming it. Battery life also seems to have improved a great deal but I am not sure yet how much. Still the first cycle since editing the file. But with deleting the .plist - it drained my fully loaded battery in 12 hours with wifi and bluetooth activated. While now I am already 6 hours into it and the battery is showing at around 80 % - same conditions.

Therefore I am thinking - the file is read (/needed?) by the power management app and some settings (not all of them) are being used. I don't know yet but I will try messing with the data some more to see if I get any better efect out of it.

If you want to do your own tests - here is what I did so far:

1. I deleted everything between <plist> and </plist> tags.
- it works but I figured that it would not bring any improvement as opposed to deleting the file.

2. I deleted just the Default Profile Choices part - did not work

3. Since the profile choices were using choice 1 for the battery and choice 2 for the AC Power - I deleted the first, second, forth and fift set of settings (AC / Battery / UPS) - this because being an array the first one would be key 0
- this also did not work

4. Since I was left with just one set of settings and no Choices part I further edited the battery settings to be identical with the AC settings
- also no good

5. I deleted just the <array> and </array> tags
- now I am up and running

So now my com.apple.SystemPowerProfileDefaults.plist file looks like this:

Like I said - the battery life seems for now to have improved - I don't know yet how much - but I think the above tries are proof that some of the settings in this file are read and thus maybe we can tweak them to have better battery life.

Hope this helps.

I have a 1.1.2 OTB iPhone jailbroken and hard-unloked with NextSim

Nice to know someone is still trying.
I'll give it a try and report here!

Mihaid, I copied your code into my plist file, I'll report back if anything has improved, have you tested if the calls and sms are always received?

Tryed!
Nothing has changed,24 hours (WiFi off) like before.

Mine actually ended up being drained even more. :/

hi everyone. i have the same probem and wnet through the 27 pages here but still dont understand if theres a fix. Is there a way to rectify this problem?
