[Q] automatically enable power saving mode when locked - Galaxy S III Q&A, Help & Troubleshooting

Hey guys,
is there any way to set up power saving mode to turn on automatically when screen is locked and turn off when unlocked?

Unless a rogue app it's m keeping your phone clocked up ,I don't really see the point, it should go to sleep anyway, all power saving does is drop max to 1.2GHz, din screen and stop vibration, non of which is going to effect your phone when it has screen off/is sleeping

there's no native way, however i found an app this morning you may find useful to your request, its called deepsleep manager. its a whole suite of battery saving options that active every time the screen turns off. didn't play around with it much so can't say really what all it offers. just throwing it out there

Power saving mode

Hi, got my galaxy S II a couple of days ago, very satisfied so far!
But I have one question I would like to ask..
when I enable the power savings mode, it says it is active even though the battery percentage is over the threshold I have set..
but I see the settings I have set doesn't get activated until the percentage drops under the threshold..
Is this the same with your handsets?

I think it's only showing notification, but it activates at the threshold you set up.
Still, I would like to have option to turn the notification off.

[Q] System Power Saving

hi,
I'm using android 2.3.6
The "System Power saving" feature seems to be turning off my Auto-Sync - i cant get push emails on my gmail. Has anyone else noticed this?
Hence im talking about System power saving and not User Power saving mode
What's wrong with that? Auto Sync uses a lot of battery as it constantly draws new data from the server every few minutes, and System Power Saving is aggressive power saving, so expect most things to be turned off, so it maximizes battery life.
because I looked at the settings for User Power saving mode. it had the feature that disables the auto-sync process.
Thats why I didn't think using System Power saving mode will also disable the auto-sync. that would be kind of like double-handling. I guess im wrong
Hey there. If you want proper and customizable power saving get SiyahKernel, voltage control to tone down max frequency and 2nd core to manage active cores. The stock power saving feature is horrid.

Saving battery on my Android device?

So after some research and Googling, I discovered that "Killling" your app is only worse or has no effect for your battery life. Even using apps that "save" battery only harm it even more. I've been told these were the fundamental things to save battery ever since I even got my hands on a smart phone.. Guess I've been asking the wrong people.
So, what are real ways to save battery? I'm a heavy phone user, often surfing the net or watching Netflix on the go. Dimming my screen is not enough, are there any other techniques to prevent my phone from dying? I've got an Android 4.
If you're rooted:
Underclock
Undervolt
Change cpu governor/io scheduler
Flash different ROMS and kernels
Change your modem
And a few more.
Not rooted:
Use screen filter? Lol.
Update your firmware

Get bigger battery?
Turn thing off lol only kidding but turn off auto updates such as news etc
If you look at your battery stats, under settings, you'll see what uses the most battery. Usually I find that my screen uses around 70% of my battery, but if you have something else high on the list you might have a "rogue app" preventing your phone from going into sleep mode.
If your screen is the culprit you can only save 10% or so by throttling your CPU etc. The only way you can make real savings is by reducing screen brightness.
Easiest way to save battery is use gemini app manager to stop apps being able to autostart when you don't want them to as then you don't have the os having to kill off unused apps to make more free ram.
For example a lot of apps can autostart when your wifi goes on or off, when your 3G signal drops etcetera including things like facebook or google play. By changing auto start for such apps you don't have to run a task killer which also saves battery.

i use the aokp rom milestone 4 atm, and i also have come accross a fantastic battery app called "Badass Battery Monitor". its free and details very very specifically what apps are using the battery most.
I have managed to increase my battery by rooting out the apps i dont use that are using prescious power...
Also, turning off useless app permissions for apps theat really dont need them and work perfectly well without them will also save on power massively. for this i use "LBE Privacy Guard" works an absolute charm
I have widget where I can turn off Internet connection, set brightness, GPS etc. Internet stand-by mode uses damn much battery... And when you don't use Internet, you can put on 2G, it also saves battery.
This may not benefit you if you are a heavy user but I find the feature on my Droid 3 that turns off 3G after 15 minutes of inactivity saves battery and also saves data. Not sure if this is a standard Android feature or if it would even benefit you.
Here with LG P990 and I don't have option to turn off 3G aftre some minutes... but if/when you didn't need high speed you can choose only 2G network (for example when needed receive only notification): this save a lot your battery.
Moreover you can verify battery consumption to see if there are autostart apps from your vendor than have heavy power consumption (for me there was OnScreenPhone) and use gemini app manager as explained previously.
In the end you can find out custom ROM for your device usually optimized for smoothness and power consumption.
First apps I download when switching to a new Rom to get a little control on battery are
Adfree- Get rid of ads, they eat a bit of battery.
DroidWall- Control what apps are able to access Internet under separate "Mobile Data" and "Wifi" Conditions.
Screenfilter- Dim the screen below factory settings.
LED's hack- Turn off the Softbutton Backlights (home/menu/back/search), even though they don't seem like it may eat up your battery, it is an extra 'light' that's on, even though it may be minimal, it's still drawing power.
Also, It maybe just a Photon thing cuz of the Pentile display but I always use if not completely Black background image, a dark one because the 'lighter' or 'whiter/colorful' images take more battery, same reason I always look for 'Inverted' or black themed apps too.
Turn OFF any 'Haptic feedback' settings on your phone (Keyboard, Phone DialPad, Screen/UI Interactions, etc..)
For Calls (Ringtone) and Notification settings, don't have them set to 'Ring and Vibrate' or just 'Vibrate' because the Vibration Mechanism will eat alot if battery. Some may argue that the Notification 'Vibrate' setting and even the Haptic feedback (which does in fact use the phones Vibration mechanism) would not kill battery because it's a 'quick' or 'minimal' use (depending on use) and but if your keyboard had the Haptic feedback on, thinking of how many times your touch the keyboard for even on Text message, try will add up and help kill the battery.
Turn OFF any/all Homescreen/UI Animations
Turn OFF any Auto Sync setting and instead have APPS sync in a specified interval, (Of course Depending on how important the information that's being pulled like Email) , Could be set to like every 4 hours to sync an so on.
Manually input Date/Time settings instead of "Get network provided values" because it'll be one less thing pulling from Internet.
Set Screen Timeout to 30 Secs and Never have Auto-Brightness set, instead use a brightness toggle of some sort (Stock 'Power Control' Widget works well) to only have it as bright as you need to view in current conditions.
Open the Google 'Talk' application and uncheck the 'Auto log-in' setting, and then 'Sign out'. For some reason this always runs in the background and eats alot of battery.
If I think of more things ill post them
Hope these tips help, if they do don't forget to hit the thanks button thanks.

There are many ways...
Switch on WiFi, 3G at only using, and close the not using application, decrease display brightness etc...
And if you root your phone, you may change CPU governor, or build.prop tweaks, script tweaks... Or change to custom kernel or custom ROM.
I forgot that 'LED's hack' is not available in the market anymore, I attached it below.
i hv just downloaded screen-filter lets c how that works...
Juice defender
Try JuiceDefender by Latedroid. It helps a lot to turn off things you don't need when you don't need them. Sorry I can't post the link- I'm new to XDA
my experience:
undervolting does not help much. you have to test a lot for only a little bit of improvement.
in my opinion you will not really remark it.
but what helps, i think, is set cpu speed, if possible. for example i use samsung galaxy s2 where cpu has max 1200mhz. i set max cpu freq to 800mhz. with a good rom (hydrogenics f.e.) android keeps running smooth with 800mhz and battery lasts noticeable longer.
I agree that undervolting doesn't help so much.
Like in up post, best thing to save Your battery is to change cpu power. You can also use diffrent cpu govenor : good for battery are smartassv2 and power save. Just need to have rooted phone and download app, fx. Antutu CPU Master or Set CPU. U can also make your cpu speed profiles.

Slight Lag With Power Saver Enabled

Hey Everyone,
Just making sure that this isn't just my phone. When I have the power saver enabled and try to input my pattern lock, if I go too fast, the pattern tends to miss a point and mess up until I restart again.
When the power saver is enabled, I think I read on the options that it limits CPU power meaning slower response, right?
I just keep the power enable setting off. I can enter my pattern fairly quickly, and I still don't run through this phone's battery like crazy, which lasts me all day.
Merry Christmas,
SlyG07
yup....
Yea it slows down the CPU to conserve energy. It says it in the power saver options

Wake screen WITHOUT mechnical button (PWR/Volume)

I would like to wake from screen timeout without using any type of mechanical button (Power or Volume Buttons). I was ideally hoping the proximity sensor with the proper app would work but all the apps I have tried (MANY) have not worked properly on the Atrix 4G (cover proximity sensor screen OFF else ON, maybe with delay option before turning OFF) I would be happy If I could touch anywhere on the screen to wake the screen. My Atrix 4G is running factory 2.3.4 and is rooted and my wife's Atrix 4G phone is running 2.3.6 and has not yet been rooted. Seems like a rock solid working app to perform this functionality should be available for the Atrix 4G/MB860 smartphones?
Any help on this issue would be greatly appreciated!!!!!
Don't want to wear out the fingerprint/power button!!!
Regards, Ron
PS-- I would gladly pay a nominal price for a working app (better than wearing out the mechnical switches)
that is not posible

It is possible, but it means it would have to keep the phone in a state of semi-awakedness at all times, never letting it go into deep sleep, thus draining the battery pretty quickly. Also monitoring the sensor constantly, thus draining even more battery. It also means the sensor would emit the faint red light all the time, which many find annoying.
Battery drain will be your best friend.

Pre-warning; I havent tried it. I just saw it a week ago so I'm sharing
Proximity Screen Off:
http://forum.xda-developers.com/showthread.php?t=876945
Thanks for the replies!!
I am aware the phone could NOT be in "deep sleep power save mode" and work without using either the power or possibly the volume button. A couple of Google Play "Pay Only" apps indicate they can be configured to wake the display using the side volume button (this would at least preclude the use of the power button to wake the display). I assume the volume button would still adjust the audio level? If anyone can comment on how well these apps work on the Atrix 4g, that would save me from purchasing an app that doesn't work as desired. From my understanding, the display uses the lions share of the battery bugdet. There are also apps that claim the display can be turned on by shaking/flipping or using the proximity/light sensors (anyone get any of these apps to work on the Atrix 4G?). The phones battery life should be extended by simply turning off the display. Waking the phone by something other that the power button would just be ONE of my usage models. If I want to get the maximum battery life, I would wake the phone using the power switch and not use any after market apps.
Thanks Again Very Much for your forum posts and any further help would be greatly appreciated.

widgetlocker lets you wake the phone by volume buttons, by disabling the stock lockscreen and replacing its own locker. it doesnt effect the sleep mode but disabling lockscreen may cause problems like unwanted call accepting. widgetlocker can put its locker over the callscreen but it still wont display the calling number. you may first try the app and then decide to buy it

Possibility to wakeup with a shake is solely depends on the kernel implementation.
