I recently bought a Bluetooth communication headset (Sena SMH10 for those interested in knowing) for my motorcycle helmet and use my phone to stream mp3 via Bluetooth to it.
Now, I know the deep idle CPU state is usefull for listening to MP3 on the phone while screen is off, but since I need to stream my music via Bluetooth, I won't be able to reach top=off.
The question : Is there a notable advantage in power consumption with DIDLE TOP=on compared to Deep Sleep when listening to MP3s ?
I can't test it at the moment as my current kernel (Slim's default) doesn't support deep idle.

I have been making some changes to my Nexus One lately because I was having some battery life/drain problems.
Here is my current setup:
ROM: MIUI 1.11.11
Kernel: Tiamat_N1-v4.1.0
Radio: 5.12.00.08
WiFi Sleep Policy set to Never
Brightness is Automatic
Not that many apps installed; no rogue apps
I just listen to music, browse the internet, and occasionally play games. (Not 3D games that require a lot of resources, just casual stuff)
No, I have not calibrated my battery yet- I'll worry about it later.
Does anybody have some tips for how to help increase my battery life? Perhaps another kernel is better? etc
All help appreciated. If you have a question, feel free to ask and I'll get back to you ASAP.
You should change brightness from automatic because automatic will constantly work in the background to check if the screen needs to be brighter/dimmer.
Also get setcpu and use this basic setup:
Main Settings:
Scaling: On Demand
Max: 998
Min: 256
Profiles:
Screen off -> Scaling = On Demand, Max = 576, Min = 256
If you're listening to music while your screens off, you may want to bump up the Max to 614 for the screen off profile if you're experiencing slowness, if not keep it at 576.
That should help your battery last at least a 10% more relatively speaking.
This is app to prevent the cpu going in deep sleep and keeps it running a 200 Mhz, this should however prevent SOD`s from happening and thus not missing any calls, mails, appointments or alarms cause the phone is not responding.
Does anybody use this app on CM9 to prevent SOD`s and does it work 100 %.
Does it drain the battery heavily or is it acceptable?
Please share your experiences and/or suggest another good working app.
My phone has a problem waking up from deep sleep. I've lowered max CPU frequency to 368 MHz for less battery drain (only when screen is off, I'm using AnTuTu CPU Master).
The main problem is when I receive a call. The phone vibrates for 2-3 seconds, and then yet starts the ringtone. Sometimes it doesn't display the contact's name, just the number. If I leave it to ring, it'll display the name in a few seconds, but is really slow.
It was happening before I've lowered the max CPU frequency, but it lasted for 1 second max.
Any way to fix it without increasing CPU frequency?
I doubt there is a solution it would be due to the phone trying to process things at a lower frequency and if the phone is in sleep as long as you don't have any apps keeping it awake it will be sitting at 200 or 100mhz anyway

hi,
i noticed the phone runs on 400mhz when u listen to music (standard player), is it possible to "force" 200mhz, i am pretty sure that it will work.
my old device had a 1ghz single core and was able to run music with 300mhz which is way less then twice 400mhz.
the battery life will be so much longer if i would save 50% while listening to music.
maybe this is something for the development section, but i am not allowed to post there
can anybody help?
thanks
Use some CPU tuner app and set profiles accordingly . I'm pretty sure that you can underclock stock kernel.

Hello, I am opening this thread since I read that some people experience problems with high temperatures or problems in loading and unloading the battery so I ask you to please share your usage statistics to check the normal statistics of our device.
Approximate charging time from 0% to 100% =
Approximate time of download in navigation, YouTube or chrome in mobile networks =
Normal temperatures in sets =
Normal temperatures in Internet browsing and normal use in mobile networks =
Normal cpu temperature in normal use =
And if possible specify the rom and bootloader you are using.
I am one of those who are experiencing problems so I want to know if it is normal or not, I expect their answers.
(Text translated by google)
yes its normal I have S4 Active for 4 years
and Installed many Rom
I think snapdragon 600 is the problem and gets hot very easily with normal internet use no matter how you change the settings
but I have two battery and they wont get hot when charging even with 2000 mah charger
___ by the way I use some cold heatsink when I share my free 4G internet using hotspot
It gets damn Hot downloading 3 Mbit/s
and eat my battery after 45 min
its much better when sharing the internet with usb tethering
and watching youtube .... no way it will burn after 15 minute
but the worst situation for me is hotspot never played a game on my s4 piano tiles long time ago
sorry I have no stats about cpu temp ... right now
Its a nice phone btw I wil use it as long as it works
