http://androidforums.com – Just did a couple of tests on my unrooted Galaxy S2 i9100 running ICS 4.0.4. You see, I'm using Juice Defender Ultimate and I've noticed it enhance my battery life. But the problem is Apps cannot underclock the CPU without root access. I was scrolling around the Galaxy S2 settings and it occurred to me that two options for power saving is present. "System Power saving" and "Custom Power saving". At first galance I thought the "Custom" mode is the same as System Power Saving option but gives the ability to change how power saving is done... IT IS NOT!!! Both are (General)

As a broadcom device, usually there is a free and non-free one.  I have very little experience with broadcom, but have seen a great number of times when it is suggested on these forums to use a different module.As a side note, my current rtl8192ce (RTL8188CE) driven card is not able to have power saving toggled while the module is loaded.  You have to specifically tell it to modprobe it

Support power saving mode 19 weeks 3 days ago

Does anyone else have the problem of when the power saving function is enabled, that the internet connection will disconnect and you have turn the aeroplane mode on and then off to get it working again? Not sure if this is part of the power saving function, or if my phone is just broken!

To my suprise when I ran powertop on my fresh fedora 17 install, powertop reported all tunables bad and fedora doesn't seem to have any laptop power saving features enabled by default, nor does it have any of the pm-utils power saving scripts in /usr/lib64/pm-utils/power.d or /etc/pm/power.d.

1. Running Juice Defender Ultimate with Lux Paid version....

2. System Power Saving ON. Note : Custom is off!

3. Google Talk is Signed OUT... (Reason for power drain)

4. Samsung Dive is OFF (Settings -> Security) (Possible bug or reason for drain???)

5. Facebook is On.. check every 2 hours.

6. GPS Off, Bluetooth Off... Sync is OFF

7. Voice Command Driving Mode is off...

For all of you who are conscious about your power usage, you probably tend to check over your power settings often to make sure that you’re being as energy-efficient as possible.

I was a bit disappointed with the battery life of crunchbang out of the gate. I installed laptop-mode-tools but that did not do much. So I hacked together a little script that will enable some power saving tweaks when on battery power, and default to best performance while on AC. It should work on most setups, but YMMV.

Powertop, a tool for detecting power wasters under Linux, is about to make a generational jump: version 2.0 provides improved diagnostic options and a redesigned user interface. It also offers a simple, manual way of enabling numerous power-saving features that can noticeably extend the battery life of notebooks. read more

I was downloading a bunch of audio tracks using "clipgrab". Had lots of time left so I went to bed and let it run. This morning PC was in sleep mode. I hit keyboard to wake it up and nothing happened. I have to unplug to shut down.
