Ive done many tests, and Ive finally achieved the 12 hour battery life everyoen has been complaining about.

This is only achievable through a mixture of the applicatoin ''Juicedefender beta'' and Smart Actions, and freezing the unnecessary bloatware that doesnt need to be running in the background

Use the following settings:
  • 2g & Data connnection off when screen off (For e-mails, let autosync check every x minutes you would like)
  • 3g when specific apps need data connection on (for internet radios enable the screen on/off profile)
  • In-built setcpu function, set min/max to 300mhz on idle
  • Enable juicedefender to automatically handle 2g/3g networks
  • SMARTACTIONS: Display ON & OFF profile -> Disable background sync
  • Juicedefender in-built autobrightness, and tweak the settings below stock brightness
  • Enable juicedefender to manage wifi

HYPOTHESIS: Played Internet Radio for 1 hour straight, all active applications killed, only radio playing.
RESULT: Every 1 hour, drain: 9%

So if you multiple 9% by 12 = 109% which is slightly above 12hours.

Everyone can also test this, and see if their RAZR is the same, if so, no more complaints =)

Which is roughly 12 and a bit hours, please everyone also share their results using the same setup and post your results so we can all share, hope this helps =)

I can run 16 hrs stock out of the box under moderate use.

Here's where I'm at now and I'm stock...

My battery life has almost tripled ever since I turned off my 4G radio.

Yes, after 3 weeks try and error, 4G is the biggest consumer of battery.

Second is screen.

Where is the built-in setcpu function? I have been looking around but can't seem to find any setting like this.

I'm aware that Juice Defender has an option like this but when you say "built-in", it sounds like you're referring to one built-in to Smart Actions.

There is no 'acclaimed' 12 hr battery is just possible with no high-tech, settings changing miracle. I get up to 18hrs with moderate use. Aside from need to put your screen brightness down to around 30% which still looks very good.

Make sure you are using the beta version. Then you must go to the profiles ans click advanced, then confirm and the extra options to change frequencies will appear

2g & Data connnection off when screen off

That basically means that unless you are using the phone with screen on you are not going to get emails.

I agree with Szadzik. There's a fine line of usability vs battery life that needs to be determined by ones needs. For me I don't use WIFI. Mine is always off and don't turn it on unless I must for a mandatory game data download or something. I refuse though to scale back half the phones ability to save on battery. Fortunately this is the best battery life I have ever had on anything and that includes my single cores. Thankfully no need to scale back. The benefit of having AMOLED or at least this one is you can run the screen at 30% and still have people comment on how bright it is LOL.
