Hi, anyone know of an app which will block all APN, always on mobile data - etc etc and only will permit them on demand with some designated applications?
I really want everything off but then when I check my email, or use a map, etc I don't want to have to be dealing with messages which tell me that data is disabled and I then have to go and activate the thing manually - and then remember to switch it off.
I want something which will automatically connect while my email program is running and then disconnect as soon as I shut it down.
I have an idea that JuiceDefender should be able to do this but most of JD doesn't seem to be working with a Desire HD. I have to accept the defaults - which means that a whitelist only starts to operate at battery - 15%.
It won't let me set it higher - although the functionality is meant to be there.
Anyway, I am sure that there is something around but I can't find it.
Can someone suggest something?
Ta
In fact I've purchased Ultimate Juice and more of the features are enabled - but it still doesn't seem to be fully compatible with the DHD
Either ultimate juice or switchoro widget.

Thanks - Switchpro, I think.
Juicedefender just about works but doesn't seemto control the wifi as well as it should.
Is Switchpro automated or is it just a collection of manual toggle widgets?
So I just unlocked the bootloader and rooted my VZ SGN. My first root! And I have been suffering, like many, from the Android OS bug that is affecting battery life. So I was just wondering, since I now have superuser access and whatnot, what can I do to make my battery life better?
I'm still on stock ROM, 4.0.2, as of now. I will start adding ROMs later on. So for now, what can I do?
thanks in advance
Flash a new kernel

This. If you're into flashing roms and kernels I'd use AOKP with Franco's kernel. It's a great combo.

I use AOKP and Apex kernel. Great match for me
thanks for all the answers. how exactly do i install a kernal? i have rom manager and all, so maybe i can use that app to do it. also, does installing a new kernal mean i have to change the ROM? and if i do install it, will all my data be safe?
and for all those who already replied with recommendations for kernals, what sort of battery life do you get with them? and how good is the signal and performance etc?
sorry for so many questions, but im new to this
Try turning off GPS or freezing maps.

I'd start by not using rom manager.
flash CWM recovery and use that to flash ROMs/Kernels. Theres a great user guide in the development forum.
This is a battery saving list that was actually written for the Bionic, but most of it will apply to the Gnex too. The main caveat is to be careful about doing a Factory Data Reset. If you do one by select it in the Backup & Reset menu in Settings it will wipe everything off of your sdcard. So be sure to backup anything you want to saved to your computer first:
If you are having short battery life here’s a list of things that can help. Just read through the list and select the items that fit with the way you want to use your phone. Not all items will work for everyone and this list was written for the Droid Bionic but should work for your phone too:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- When you get a 1) new battery, 2) do a factory reset, or 3) an OS upgrade - run your battery all the way down until the phone shuts off and then charge the battery all the way up. This will calibrate the phone's understanding of the battery's capacity. Do this once every month or two also, but don't do it too often if you can help it.
- I have my battery set to "Performance Mode" and data is on all the time because I am on call 24x7. If you don't mind, try out a more conservative battery profile to save more gobs of energy.
- Set screen brightness to "Automatic"
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
- Turn on Bluetooth only when you are going to use it.
- Consider turning off voice privacy. This may not be a big deal but it will save some processing (and therefore battery). It may also improve call quality.
-Turn off haptic feedback, animations, and any un-needed sounds in Android settings and in your apps
- Set your screen timeout to as low a time as you can stand (I use 1 minute) and manually turn the screen off when you’ve finished using the phone.
- Turn off in-pocket detection. In-Pocket Detection has been the source of many issues already.
- Keyboard: turn off vibrate on key press and sounds for any keyboards you use
- Use a red or black screen background. On the original Droid screen--not sure about this Bionic screen--red was the most efficient color that could be displayed.
- Camera app: I like keeping location on and flash on auto. Consider turning location off or at least returning to the home screen ASAP when using camera if location for camera is on.
- In stock browser the default home page is Google and it uses your location. This is a bad idea as it can waste your battery for no reason. Make something else your home page and make sure to close any web page that uses your location when you're done viewing it.
- Charge your phone via the wall charger instead of computer USB as it is faster. Also, don't use long USB cords--use regular power extension cords instead. I stick with the charger that came with the phone. Put the phone on charger when you go to bed every night.
- Consider install the Home Replacement app Zeam. It is basic app that uses very few resources and will help with battery power.
- Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail.
- If you are using Live Wall Papers, stop!

If battery life is still bad: Consider doing a factory reset: These have gotten pretty painless lately by following these simple steps: 1. Make sure Backup and Restore are checked in the Privacy setting. 2. When going through the setup after the reset, turn on wifi as soon as you can (assuming it is available). 3. After you have entered your Gmail account info, you will be presented with a screen that has two check boxes. Basically they are "Do you want Google to backup and restore this phone”. Make sure you check both of those. Your apps will then automatically reinstall (paid and free). Set the phone aside for a minute or two and let the apps download and install. 3. If rooted, use an app such as titanium backup to restore data only to select apps such as Tapatalk and you will not have to re-enter all your login information. I do this for 3-4 apps (Tapatalk, SPB Shell, etc.).
I've been flashing new roms/updates about once per day lately and I can be up and running with all my apps and settings back in place in less than 20 minutes. It's pretty painless now.
thanks for all the responses. i think i might flash AOKP and franco's kernel on my SGN.
I have a couple more questions though.
1. So if i wanna flash those two, i can simply flash the rom and then flash the kernel right after, without have to re-wipe my data or anything like that?
2. does the backup feature in CWM backup app data and homescreens and all? or do i need titanium backup or something? or is it just not possible for me to do?
3. and if an update comes out for either AOKP or the kernel after i have flashed it, do i need to wipe my data again and flash the latest zip file or can i just update over the existing one?
thanks
also, do i install the kernel first or the rom?

Hi Guys,
I wanted to know what any of you find to be the best app to find a lost phone. I wanted to know what the best app is to date since things can change over time, and I havent used this type of service for over a year. Some features I'd like are GPS tracking but little to no battery drain, and the ability to sound an alert even when the phone is silent or on vibrate. Thanks for any and all input.
Just me but I use the one that comes with 'Kaprasky Security', it is very accurate in my country of Canada so just try that or wait for other responses

Cerberus is by far the best.
This is what I use and is the best and has lots features highly recommend.

I second this. No monthly or annual fees. Just pay $4 one time and it covers up to 5 devices.
Here's some of the features:
It has three ways to protect your device:
- Remote control through the website www.cerberusapp.com
- Remote control via text messages
- SIM Checker (for devices that have a SIM card): you will automatically receive alerts if someone uses your phone with an unauthorized SIM card
Remote control allows you to perform many operations on your device, like:
- Locate and track it
- Start a loud alarm, even if the device is set to silent mode
- Wipe the internal memory and the SD card
- Hide Cerberus from the app drawer
- Lock the device with a code
- Record audio from the microphone
- Get a list of last calls sent and received
- Get information about network and operator the device is connected to
- And much more!
Cerberus automatically enables GPS if it is off when you try to localize your device (only on Android < 2.3.3) and you can protect it from unauthorized uninstalling - more info in the app configuration.
The app works even if the device does not have an internet connection thanks to remote control by sms messages. Also, the SIM Checker feature allows you to know the new number to send texts to, if the SIM card is changed. Texts received and sent for Cerberus remote control will not start any notification and will not appear in the Messages application.
Cerberus does not drain the battery because there is no background service running: it will activate only if there is a remote control request and will stop afterwards.
More features for rooted devices: complete uninstall protection (a thief will be able to delete Cerberus only by flashing another ROM), GPS auto-enabling even on Android > 2.3.3. More info on the website in the Help section.

I used that to find my wife's phone. Did a remote install too as I didn't have it on the device. .. Amazing.
I've heard a lot about Cerberus, but it needs to always be running on your device from what I can see. Can you remote install and configure it only when you need it? If not, that's a pretty dangerous app to allow basically all functions of your phone to be accessed online...
I use avast! Mobile Security. You can install the application and then enable Anti-Theft. Once it's set-up and installed, you can uninstall avast! Mobile Security. (I'm unable to provide links, but they have a webpage that describes the necessary steps better.)
You can then use a bunch of different commands via text message to locate/lock/unlock/etc. your phone. You can specify two phone numbers to be the only phones that can communicate with your device, or you can leave it open. (Commands sent to your device must contain your pin code and then the command.)
The FAQ for the app says it does not run in the background and is only activated when a text command is sent to the phone. (I think this program only works if you're able to receive text messages to your actual number. Not via Google Voice.)
avast mobile security is awesome!
I use cerberus...they have features such a remote recording of video and audio which I don't think is available on SeekDroid which I was on before

You can buy a ball of yarn at the hardware store for a few cents. Tie one end to the phone, one end to your wrist.
Never lose the phone.
Avast can get location even if GPS, wifi, mobile data and location service are turned off, if you are rooted. Cerberus can't.

Okay... I just tested it now with Cerberus dashboard (online website where you can send commands from) with my phone unlocked right in front of me. Sent command "start tracking" and saw with my own eyes the WIFI and GPS toggles go from OFF to ON. Wifi and GPS still on... Sent command "stop tracking" and WIFI and GPS toggles went from ON to OFF.
---Edit---
Sorry, I was wrong about the administrator privileges, by enabling that, it will allow you to erase your data/sd card remotely. To get WIFI and GPS to turn on when you send the tracking command, you have to push Cerberus to /system/app
I see a flaw in all of this:
Factory reset = GG

Cerberus help page, and I quote:
"I have a rooted device. Can I get additional features?
Yes! If you have rooted your device you can integrate Cerberus into your ROM and get two additional features: complete uninstall protection (Cerberus will even survive a wipe/factory reset) and GPS auto-enabling even on Android 2.3.3 and later. To have these features uninstall Cerberus, then download cerberus.zip, put it on the sd card and install it from recovery. Cerberus is also available on ROM Manager."
Taken from avast! Mobile Security app page, and I quote:
"Self-Protection
Extremely difficult for thieves to remove (especially on rooted phones), Anti-Theft protects itself from uninstall by disguising its components with various self-preservation techniques. On rooted phones it is able to survive hard-resets and can even disable the phone’s USB port."
Unlike many modern versions of Android, I can find no three-tiered setting for GPS accuracy. I'm looking to set it to "Device Only" but it's either off or on, with a few additional location options but nothing more for GPS.
I'm using lineage 17, the second to last update, on a Samsung Tab 4 and I just want to restrict the device to the system GPS app GPS I've set (but it keeps drifting).

I'm not tin-foil-hat-concerned with Google knowing my location; I'm referring to the systemized GPS app I installed to be able to determine the location I set. Which it can currently, and can usually continue to do when I can set the device to take GPS from "device only". In this case it shows me on the map "rubberbanding" between my actual location and the location I've set about 100 feet away. This is because the OS is allowing the device to try and locate its own location.

Oh, location spoofing
https://f-droid.org/app/com.wesaphzt.privatelocation
GPS drains battery
With previous (before 17) it was possible to set the location service to be switched on, but only use cell data.
When I use the gps device it drains my battery much faster.
Therefore: How can I leave the location service on, but DO NOT USE the gps device in LOS 17 ????
Thanks in advance

Do you try to spoof your location? And why? What location providers do you have? GApps?
I guess your reply refers to my question.
Maybe I was not clear.
With former LOS versions I was able to explicitly choose whether to use the (battery draining) gps receiver for my location or not.
I have several other sources of location information (gsm cell based and wifi based) usually with less accuracy. But I may prefer theses under certain circumstances because of less power consumption. I Don't use google but microg.

No. I am not trying to spoof anything. I have an automation program called Tasker on my S4. When I was on stock Samsung ROM (5.0.1), I was able to use the "location mode" in Tasker to switch between high accuracy and battery save. If Tasker detected I was running Google Maps, it switched on high accuracy. If not, it switched over to battery save. From what I can tell, high accuracy used GPS + network and battery save used network only.
Now, I'm on LOS 17.1 and battery save would turn on GPS too. It seems the only way to not use GPS is to turn off location mode altogether. This makes me wonder what the differences are between Device Only and Battery Save modes. Since I cannot tell, I am assuming both modes are provided for backward compatibility to Tasker users but the underlining Android 10 doesn't differentiate them.
I am suspecting with Android 10, there are only 3 modes.
* GPS + network
* GPS
* OFF
Thus, if one needs the location service, GPS must be used.
I raised this question elsewhere. Some people actually told me that GPS doesn't consume much power if it's just turned on but not being used, e.g. by Google Maps. I have no way to verify if they are right.

Network location is not part of lineageOS. You can add it with GApps or microG. Have you?
Enabling location does not power the satellite receivers continuously. It really needs battery. The job of your tasker script is done by android 10 automatically. If you suspected apps to drain battery with GPS, disable their location permission!

The reason I preferred to keep it on battery save instead of off completely in the old days was that if I ever lost my phone, I wanted to be able to track it. Now with Android 10's mandatory GPS for location service, if I want to disable abusive apps from requesting unnecessary location service, which app should I avoid disabling? Which app is giving out my phone's location if I am tracking it remotely?
Thank you

I still see one drawback with very selectively granting apps location service. For example, I do want to grant Chrome location service to facilitate better search. If I'm indoor, wouldn't GPS without a clear view of the sky trying very hard to get a fix and thus burn more power than necessary? With that said, can High Accuracy (GPS + network) actually be more power efficient under Android 10 than Battery Save (GPS only)? This is assuming Chrome would give up on GPS when it can't get a fix and be happy with just network while Battery Save would keep trying to get a fix with GPS. Again, this is just my assumption.
So as one can see, i got a lot of apps on my device and since device care couldn't come with the option to select all for adding apps to put to sleep, it's an extreme headache. As you can see from the screenshots, i get this message like once a month or so and it changes all my sleeping apps list and adds them to deep sleeping which I don't want. Is there a way to disable this thing?
Putting apps to sleep ie using any power management can cause erratic behavior even more battery usage.
Start by using Karma Firewall (Playstore) to lock it down as needed and PD MDM to disable the apks that are causing trouble.

You don't have to use Device Care, if you should be able to disable after you pick the power setting and enable fast charging, those changes will still remain in force.
I'm running on Pie and have a earier, more user friendly version of Device Care on my 10+.
Q and especially 11 are going to be major headaches. The logging feature on Karma Firewall is disabled by them I believe.
It still will block internet connections but you can't monitor what app and how many times it is accessing the internet like I can on Pie.
There may be a ADB workaround, not sure.
Sorry but Q and above are bloody nightmares...
