app that turns off data on screen lock?

Hey all,
I tried searching but came up empty, is there an app that specifically turns off data when you turn your screen off or lock the phone? I read that juicedefender does this but was wondering if there was a app that is designed to turn off certain things when locking phone.
thanks!

Well you basically said it...you can use juice defender, or look into the tasker app.

Juice Defender ftw

I've been looking into this same issue. After looking around and getting some advice from another xda member, I went with juice defender which has been outstanding so far.
If you heavy, heavy usage, you won't really notice a difference. However, if you use your phone, set it down for a while, use it again, let it sleep... all throughout the day, you will notice a significant increase in battery life. The first day I installed it, I sent a text while I was at work and then set my phone down. I grabbed it almost 3 hours later for something and it had gone down 1%.

While JuiceDefender IS designed to save battery life and such, it is designed to do just that. Meaning in order to save battery life, it disables and enables certain connections when the screen is off/locked etc.

I totally agree with you on the type of usage. If your screen is constantly on you probably won't notice a difference. Juice Defender saves battery when your phone is inactive.

doesnt the evo already have a disable always on mobile data option?

If you're on Sense, there's a widget for it. On MIUI, it's in the pull down bar toggles

Sorry to be a very late reply, but...
Does JuiceDefender turn off Mobile Data while wifi is connected?
I only ask because i have installed it, and it doesn't seem to be doing this for me.
Seems odd, because i don't need Mobile Data on while wifi is on.

Well if it doesn't do it jus go into connection settings and turn it off or if the ROM your running has quick settings in the pull down see if mobile network is there if it is just uninstall juice defender and make it a routine to click that before you put your phone down or in your pocket

Battery effiecient settings tips for our 1X (May help some with battery problem)

I am on Stock Rom (Forgot to mention this)
I average about 3.30 hours of screen time with my settings everyday, today I had 4.30 hours, 1.4 Internet surfing, 30 min voice calls, and 12 hours of wifi, total time 22.54 hours.
This is my best so far: http://forum.xda-developers.com/show...79392&page=114 (I think I can reach better results (Have better average results now)
Also please feel free to share your settings.
My settings:
Unlocked and rooted.
LED Notifications off (except for SMS).
Fastboot in power settings unticket.
Sound Settings - Turned sensors Off: Quiet ring on pick up, Pocket mode, Flip for speaker.
Brightness Control using this app: https://play.google.com/store/apps/d...rightnesslevel (I mostly leave it at 15% its more than enough for my vision at least, then if out and its really sunny I just switch to 50% its a widget so its easy to use).
All vibration settings,haptic feedback and stuff off(except for phone calls).
All auto-sync off (everything updates when you enter it like email and weather and others so no need to be on).
All animations Off (you won't notice any difference after awhile so it might as well be off).
Phone dial,keyboard and other tones off.
In developer options-> Background process limit set to 3. (Reverts after reboot/restart)
Using Core Control, can be found here (Must be rooted) http://forum.xda-developers.com/show....php?t=1652136 and I have it set to 2 cores. (Reverts after reboot/restart)
Have the backlights on the 3 capacitive buttons on the bottom off at all times using Tasker using a mod made by backfromthestorm, credits go to him and nobnut, mod can be found here: http://forum.xda-developers.com/show...1657619&page=3 (Reverts after reboot/restart).
Another mod from backfromthestorm (which can be found in the link above aswell)is better multi-tasking which changes the values in sys/module/lowmemorykiller/parameters/minfree file to 1536,2048,3584,5120,15360,20480, I set the values using Tasker. (Reverts after reboot/restart).
Another thing I do before going to sleep or not going to use the phone for a few hours is I use the built in app Task Manager's and kill all tasks and then turn the screen off, by doing this I have noticed that battery percentage doesn't mysteriously drop without using it.
Can't remember what other settings I may have at the moment but will add if memory allows
I have frozen the following apps and others:
I thought this way would be quicker and easier, I hope at least excuse my laziness otherwise

Old thread copied and up with moderators consent.
Old thread was closed due to pointless flaming.
Old thread could not be re-opened so I copied the contents, I hope people that comment here keep it clean and to the subject.
Decent stats:

This was pretty much hardcore non-stop usage.
This was pretty much not letting the phone rest from the moment it finished charging.
Will do some video tests later to see how long it can last while watching some HD flicks.

Thanks for all the tweaks, I have never had more than 2.5 hour screen time. Ill shall now use some of your settings to mix my own frozen yogurt (edit Ice Cream yogurt) . So far CM9 seems to be my bag, but I bought the phone for the camera...

Very useful thread, thanks
Just one thing though, the LEDs used for the LED Notifications use so little power that you can leave them enabled and it will drain next to no power at all! Not sure about the capacitive LEDs though, I can't imagine they use much power either!

You are welcome, yeah I know that the LEDs may not save much battery at all but one thing I like about the capacitive lights is that I have the options as widget shortcuts on my screen so I can turn them on when I feel like I need them, but most of the time I keep them off

Thanks at first since it's a piece of useful information.
But I can't keep myself wondering. what do you use this phone for since almost everthing is frozen.

[Q] PowerManagerService wakelock

I am monitoring my battery through BetterBatteryStatus. I see that the PowerManagerService kernel wakelock is keeping my phone from going to sleep. It keeps the phone on for nearly 120 mins in a day. Any idea of what that could be? I suspect that it is due to the Smart Stay feature of Galaxy S3 and I just disabled it now.

I'm getting this on CM 10.1, so no power stay. Wondering what it is too though.

PowerManagerService is basically a catch-all for partial wakelocks (wakelocks requested by non system apps). To see which apps are actually requesting the wakelocks, go to the Partial Wakelocks screen.

Is there any way to drill down this service and detect what exactly is draining the battery?

Use Better Battery Stats. instead of looking at the Kernel Wakelocks, switch it to partial wakelocks, and if I understand correctly, the sum of the partial wakelocks is effectively the powermanagementservice wakelock

Just wanted to say that i too had a lot of partial wakelocks draining battery on my SGS3 CM11 (using ART) but I've managed to solve the problem via cleaning the cache in settings->storage. Since then, the CPU is awaken only 19% of time and my batt last 5/6 days with WiFi, Now etc.. (I have a 7000mh zerolemon)

Have you seen any benefits by switching to ART?
If I clean the cache, what will it delete? Will I lose all my App settings and game levels? I have about 54Mb in there.

I just tried clearing and a message came up saying "Security policy restricts clearing of this app's cache."
Is this normal? How can I find out which app is causing the problem?

I have a Samsung galaxy note 2 and every time I lock lock my phone it suddenly turns right back on. It's been happening for two days now. I've tried factory reset and hard reset.. nothing seems to work. Looked at several forums but none seem to help either. Use wake lock app and it says this ..see attachment

Same here with various audio partial wakelocks that add up to 12 days of kernel wakelocks. This started when I upgraded to:
gapps-kk-20140606 & cm-11-20140611-snapshot-m7-snapshot kernel 3.0101-cyanogenmod-g329d6a1 build03 #1
I have gmail sync disabled but contacts sync on. I notice CM have added apollo to the lockscreen so this could be a bug I need to search for

What do mean by 'better' and 'wonderfull' specifically?

Verizon took out Battery Saver, here's Qualcomm's solution: Snapdragon™ BatteryGuru

I, and a few other users have noticed that Verizon decided to have HTC strip out their battery saver toggle on the Sense ROM (4.2.2) that ships on VZW's One.
Luckily, Qualcomm provides a standalone application which covers 90% of what the toggle does.
Snapdragon™ BatteryGuru
https://play.google.com/store/apps/developer?id=Xiam+Technologies+Limited,+a+Qualcomm+company
(personally, I haven't found the need to use it yet, but I figured it would help some people)

Thanks man, I was looking for that battery saver mode everywhere, but I guess this will do as well.

Thanks for this info. Anyone know if this is particular app will perform better from more generic battery extenders like Juice Defender?

According to the reviews all it does schedule syncing. Don't know how that is going to save battery...

Battery saver apps are a joke. The only thing I liked about power saver mode was that it cut the CPU frequency down and cut data off after a certain period of time. Other than that, if you need to save more just turn your brightness down, turn off bluetooth, use WiFi as much as possible, and use the phone less.

I normally agree - I realized the other day though, that I don't need background *push* email - but I'd like to have my phone "fetch" email every time I wake it up. Anyone know of anything like that?
(there is a manual setting, but it is when you *enter* the mail app, I'd like it to fetch every time I use the phone.)

Think about how often you "actually" need to have your emails and set it to that. For me, my Yahoo emails I don't need it to check but once hourly. But Gmail is push automatically so I won't mess with that. My corporate email defaulted to push but I often don't need it to constantly update and annoy me so I'm contemplating on 30 min intervals. Setting your emails to longer intervals should reduce that "email stress" that most people seem to endure these days.

The app has low power mode controls.
You can turn off mobile data during inactivity.
Some other features.
It basically gives you battery saver control on any Snapdragon based device.

Lol you could always just use BoneStock ROM. Andy threw the battery saver apk from (can't remember dev's handle. sorry) back in it.

It limits CPU, dims display and disables vibration feedback. Basically everything you can do yourself in stock and if you have a CPU app like SetCPU. Just a one click option that Verizon took out bc they hate battery life I guess idk.

Im running bonestock now, and the power saver has increased my battery life fairly significantly, i'll take that, because at first i wasnt impressed with the battery life, and i watched the ifixit tutorial on how to tear this phone apart to replace a battery, and i want nothing to do with that

battery drain

So I'm not going to lie... I'm hating this phone.
Camera is awful and now I'm getting massive battery drain.
I was at 100% and unplugged at 2am by 7am without any use at all my battery was down to 89%. I've found the battery stats but it doesn't add up.
Is there anywhere I can see the hardware usage?
So far I've dropped the screen refresh to 60htz, resolution to HD, dark mode on, always on is off, tap and lift to wake are off.... my 2 Yr old phone didn't drop this much!
Can anyone help? I'm really trying to salvage something from this phone but if the camera issue isn't sorted by Samsung and I can't get more than half a day battery out of it I fear this maybe the biggest waste of money ever

so in 30 mins of being unplugged on a full charge, not being touched or used at all the battery has dropped by 3%

Exynos ?
Sent from my a40 using XDA Labs

same here - i dropped rez from 120 FHD to 60 FHD thinking is going to improve but had the same battery life - so it doesnt look like its the refresh rate but rather something in the background - could be phone trying to find a 5g signal - as am outside - DK - still is rubbish

exynos990. can i turn the 5g off?

Samsung unfortunately still failed to optimize its Exynos processor so you have to manually sort everything out .. all the apk that don't need have disabled and ones i use less have put into a deep sleep... 96Hz refresh rate, 70% brightness, sync., location etc.all on ...WiFi/data 80/20%... all under ideal conditions, at home (due to self-isolation) .... and after that it looks like this...S20 Ultra-Exynos

2. Go to settings >> Device care >> battery >> app power management..
- here you can put the app to deep sleep etc...
...... do this ... for now [emoji3]

So iv installed a battery monitor and the screen is using around 1% every 4 mins. I'm on dark mode, 60hz refresh, auto brightness, HD+

I have s20 Exynos 4G and was also shocked by the battery initially. Some things that helped:
- Did a factory reset and setup everything manually, with data moved by Samsung Switch battery was dying in 2.5 hours
- Disabled Edge panel, seems it used location a lot
- Put Facebook into deep sleeping apps
- Turned off AOD
After the above, my phone is reaching 4.5-5 hours SOT, display at [email protected]

I was thinking of the next phone I buy as I doubt if manufacturers like Samsung will debloat their OSs as much as we want, so being able to disable some apps is useful.
I did it on my stock S5 years ago, just one of those things I had forgotten to do on this as it's only a few days old.
