Is it bad to turn the power save mode all the time? And what about turning it on while charging? And what is the best battery percentage to turn it on?
Any help would be appreciated.

When your battery's low. It usually turns itself on at 20%. Least on i737 is not going to hurt anything. Just cuts off cell data and such to save power

No problem to keep power saving mode always

The power saving mode only reduces brightness of your display slightly ...and turns off some of the radios that are inbuilt...also it reduces the cpu usage...these all contribute to saving battery...or at least allowing it to last till the last possible moment..
Having it on all the time...even while charging is no problem at all...it has no affect...
but since it does reduce cpu power... there is a chance of lag in some games and stuff like that...i say it with personal experience... also if you are always checking benchmark scores...it will reduce....so you can use the power saving mode wisely....once again..no harm in using it all the time hope this helps
Im always on power saving mode cause, well.. I don't notice any difference at all whether it's on or not.. Except it kinda improves battery life. I only disable it whenever I'm playing heavy games

ther is a difference when turning on/off the power saving mode..it limits your CPU frequency to 1200mhz rather than getting 1600mhz on your CPU..try installing Cool Tool from playstore so you can check..

Is this true that when I turn on screen rotation option the phone will drain battery much faster?
Maybe not "much faster" but it definately drains. Any time you processor draws power for any task, or graphics redraw, it uses battery.

OK. My wife phone is really crazy draining battery like it's crack. Soo would like to know anyone using this. What's your set up. Should I do load on bootup etc? Scaling set to? When screen off so forth. She's on SC 2.9.2 with jt kernel lastest one. Thx for the help guys.

Interactive. Ondemand. Conservative. Performance. Pretty much self explanatory right? Does anyone have a nice guide for fascinate? Maybe. I set up 400mhz on sleep and.it would power on after putting on lock.

I'm not having battery issues and I'm running just the 2.2 leak with JT's 327-2 kernel. Just set CPU to conservative and maybe drop it down to 800 mhz. I spent the majority of my day today talking on my phone and playing cordy and I was at 50%.
You can give this a shot it could just be giving weird info on the battery level. while the phone is on, charge the battery to 100% full. Turn off phone plug it in and charge to 100% again. Boot phone into CWR and clear the battery stats. Start phone like normal.
Hope that helps.
Install spare parts and use the Battery History feature and check for a wakelock. Thats the prime reason why a phone will drain like crazy.
To check for a wake lock Spare Parts> Battery History >And look to see how long it's running. If it's a really high % and the screen has been off you have a wake lock.
To find out what's causing the wakelock click "other usage" and choose "partial wake usage".
If it's Android system it's probably the GPS doing it. So turn off the GPS unless you're using it.
Cool ill check those out.

So setcpu useless then? Or does it even make a little difference with the battery? On sleep at least?
Sent from my ADR6400L using XDA Premium App
I find the phone to do a good job of managing itself but I also haven't played with setcpu alot. A sleep profile probably wouldn't hurt things... but someone else is probably better suited to answering your question.
The only thing I'm using it for now is for a temperature profile to act as a failsafe if the phone/battery start gettting too hot.

Just speed up the minimum mhz for the profile. I believe 400 would be okay, try it.

SetCPU may help with battery life however you are better off with JuiceDefender in my opinion. This will automatically turn off items not needed when phone screen is off.
If battery draining is your real problem, this thread may also help:

Set CPU isn't really fully compatible with the fascinate. The author says use a certain profile but it doesn't help much. When i used set CPU, my phone would go to sleep endlessly and I wasn't able to turn the screen on. This is because there was a bug causing it to go down to 19.2Mhz even though I set it at around 400. I had to pull the battery to solve this.
I have found that running Setcpu freezes mine up anytime it goes into sleep mode not matter what speed it is set at. The only way I was able to fix this was by removing the app, reflashing the kernel, and reinstalling it.
Have you tried to charge to 100% with the phone off, boot into recovery, and clear the battery stats? Run the battery to death before charging and you will have improved battery life.
Ill try to do all those advices guys. Thx for the info.

Do NOT run the battery to "death". This actually is bad for the battery. Every time you do this you will kill cells that will never come back giving you less life per charge of the battery.

You are right.
I meant run it super low, it may even display 0. This allows for better calibration of the battery.

The profiles definitely do not work on the SF. The app doesn't really get along well with any of the Galaxy S phones. I run mine at 800 max, 100 min and on conservative. It brings it down to around 100 mhz when sleeping, and back up to 400 or 800 when using it. Don't enable any profiles, as it will cause your phone to freeze when the screen goes off.
There are two things you can use SetCPU to change/edit that I have found won't cause problems. You can change the min/max clock speed the phone will run at and you can change the cpu governor. I had issues with Set on Boot enabled, though Profiles are the biggest issue. The info tab is also useful for looking at information about the kernel and system.
I hve been using my phone on power saving mode from 2 days to save battery and to hve more life out of it. I wana ask tht it is ok to use it continuously on power saving mode forever??
Any ideas??
No problem in using power mode all the time. It's a feature Samsung enables to save battery
Yep. Can't see a problem except the expected performance downgrade etc.

Personally I hated the power saving modes in every smartphone i had cause it affects performance. I will buy a spsre battery and a charger. If you are ok with the performance in power saving mode you should use it!
Enjoy your phone to its maximal potential. Don't let the battery saving issue to disturb your user experience.

Not the case with mine, I notice a decrease in performance. It most likely under clocks the CPU...
In regards to the original question, no there is nothing wrong with leaving the phone in power saver mode. In fact you could probably argue that its better as the phone creates less heat.
Ideally I'd like to overclock mine
Well there is no such thing as saving power without sacreficing preformance. (unless you undervolt it or use more power effectient drivers)
But you should be ok running in power save mode all the time, although I do question why you bought a top of the line smartphone then. I think you would have saved more power (and money) buying a lower end phone.
It does govern the cpu. You can uncheck it. I leave mine checked.

Truely speaking i cant see diiference of even 1% in comparison to power saving and normal mode. Any one knows y battrey depleting though good but at same rate in both modes??
juice defender app does a good job for me. i use the basic settings but you can tweak it to save more battery.
Power saving appears to cap the clock speed at 1.0 GHz rather than 1.4 GHz and it may also disable cores, too. Most of the time it feels just as responsive to use. It is less snappy for some apps and benchmarks quite a bit slower, but I feel I'm splitting hairs as it still feels quicker than my last handset.
I see two days of moderate use with Power Saving on. I don't quite see two days with it off, but the difference is probably not statistically significant and the device is still new.

im using a power saving application on Xperia S ... is it okay to keep it working all the time??
thank you ....

Yes, should not use battery/ram optimization apps. They interfere with androids core system.
I uninstalled all these apps after trying and researching. They eat more battery then they save. I only use battery stats apps to keep a log of battery drain.
Now I easily get 40+ hours on my S3 with moderate uses.
Dear Brothers & Sisters,
My new Xperia Sola's battery drop 5% per hour without any use. 3G data is on, but background data is off (as i have started the power save mode).
Background running app only facebook and whatapps, is it normal that battery drop 5% per hour with screen off ?
Thanks!
doesnt matter if backdround data is off, facebook WILL try to update the timeline in the cycle you've set it to. so yea pretty normal to me as the sola doesnt have a huge battery.
Same problem here too!
Even if you don't use your phone still the battery drops almost at a constant rate of 4% to 6% and that is very annoying. Hoping Sony would fix this issue with their next OS update.
But sola users have an extreme advantage of fast charging. Sola charges itself about 12% in hardly 10mins. Thats the better part

Hey guys,
5% an hour is 20 hours. to me that is pretty dam good. i used to get about 16 - 18 out of my arc S. with everything on.
Your Data connection is a mega killer weather or not you have background data on or not. it is the connection to the tower that drains the battery.
my arc is now just a phone for work and without the 3g on I get over a week out of it.
we all need to remember that these phones are not like the old nokia's and stuff. modern phones need modern charging habits
Pvy.
You shoud deactivate LiveWare widgets and services because it consumes a huge amount of power. Sometimes I get even +48 hours of standby on my Xperia U.
Try this out! It worked for me!
Okay! I fiddled with my phone a bit to improve battery life and it did work!
Go to settings> Applications> running
check the applications using a lot of RAM and has been using the phones active state for long time. Delete those useless apps. Also apps which connect to the internet uselessly consume a lot of battery!
It worked for me! Now my phone discharges just about 2-3% in 6 hours. Its because earlier my phone wasnt going into deep sleep mode where it consumes the least battery!
Now its battery standby has boosted up a lot!.
I'm happy now!
Try and tell me whether it worked for you guys or not!
Yeah. Disable Bravia display, reduce brightness, switch off data and WiFi, kill useless running background apps, disable widgets. I lose 2% battery in 6 hours in standby mode. I do these before sleeping and its damn effective. Also root ur phone n install autokiller memory optimizer and set aggressive values. This enhances phone speed and also battery is improved

Well the smart thing to do is to turn on the extra stuff only when needed. It's still a smartphone even when gps is turned off for example

.
might want to turn down the screen brightness to under 50% if it isn't already, and set the screen timeout to a lower setting, 30 seconds to a minute. other than that, disable all the bloatware and you should get at least 15-20 hours.
Check screen on time and write it here.

I am using app called deep sleep battery saver. It puts your phone in deep sleep whenever you are not using the phone. In whole night only 1% battery used. I get minimum of 1 and half day of battery backup.
I see mine only drains fast when i am using 3g data connection.

Battery issues are very hard to troubleshoot over a forum. Turn off anything you don't need, i.e. WiFi, GPS, Bluetooth, etc. Looks like your screen is sucking a good bit of battery. I use my phone as a WiFi hotspot at work and it gets me through the night. Not sure what your specific issue is. Try one of the battery saving apps.
