I was thinking, as a battery-saving measure, if it would be possible to have an app that would turn the mobile data on and off every, say, 30 or 60 seconds.
This way, you effectively still have "instant" notifications (minus a 30- or 60-second delay), but you are saving battery because half of the time mobile data is actually turned off.
Is anybody aware of whether or not this is possible, or whether there is any app that does this? I know there are apps that let you schedule different tasks (such as turn off Wi-Fi at 12:00), but I guess I'm looking for an app that would let me specify something to the effect of "Do X every X seconds."
Any thoughts?? I wonder if it would save a significant amount of battery.
there is Tasker for that and I'm currently using it. But of course u need to set up the profile yourself.
That's good to know. With Tasker, can you set something on a timer such as "Do this every X seconds?"
Also, do you happen to know if this idea would even help? It seems like it might, but I'm wondering if it would actually make a noticeable improvement.
I think it would use more data than it would save. Turning on and off data constantly would probably drain the battery than it would from leaving it stable.
Check out juice defender. Every 30-60 seconds won't help you much, but once per hour for three minutes or so will.
Also, see apn droid.
I'm using Tasker to turn off data when screen is off and then enable it every 15 min for 1 min

Exactly what I was thinking, since it has to scan for access points and establish a connection each time.
That said, Tasker's time context can do "between A and B, every X minutes".
CPU Tuner... it has become one amazing piece of software...
If you're rooted and overclocked, it will let you fine tune just about everything in a non confusing way.
In profiles you tweak mobile data (with "pulse", you specify how many minutes on and how many off), gps (if installed as system app), wifi, sync, bluetooth, toggle 2g/3g... and of course cpu speeds and governors...
Actually, pulse can be applied to all the above "togglable" items except the 2g/3g for obvious reasons.
In triggers, based on battery level, you can choose what profile to use depending on whether the phone is plugged in, the screen is off, or on a phone call (beta feature)
No, it's not my app. It's free and I'm helping with testing out new features
The pulse feature was just added to yesterday's update.

Mobile data turned on and doing nothing uses nearly zero battery. Reconnecting it constantly like this would make syncing of everything probably happen every time it reconnected. Possibly your accounts would re-sync, email would have to reconnect and sync, your weather apps etc might sync now that the phone has connected again, etc.
Sorry, sounds like a really absurd idea.
Is there any practical reason to install these battery-saving apps? Most of them I have seen just tweak the menu options of your phone you can already access manually and give no additional functionality to the phone itself that you couldn't already do.
Is this any different? Or will it just sit in the background consuming battery life itself just to run its "function"?
I've always had horrible time with these "battery saver" apps
Just let android do its thing
Turn brightness down, turn off GPS, BT and 4G/LTE when not in use and lower the intervals of background updates (and by that i mean turn the time up higher lol) on apps and your battery should last longer

I used Juice Defender for awhile and realized it wasn't what I wanted. I tried Easy Battery Saver and that really helped out a lot.
What it did was to disable all internet, GPS etc when not in use or screen locked. It really helped out a lot in helping to save battery
I don't find they help much anyway and will just drain your battery faster, I think they're kinda designed for the average user who keeps everything on and don't know how to do all the things alot of us who are more better with Android already do.

It offers some useful functions (such as the delayed screen lock), but I found that it messed up critical functions on my phone and didn't save much on battery.

All I had is bad experience with battery savers and they drain alot more then they save for me plus I already turned off all online stuff like Wifi, bt, 3G, mobile data etc.
Juice defender pro is doing a great job for me. Recommended! No joke at all.
Also it has come to my attention that it has a feature of learning. The more time you have it in your phone then it will do a better job to save you battery. Also alot of settings to do depending on how much juice you want to save.

On my phone, I used to run Juice Defender all the time. After awhile, I realized all it was doing was turning 3G off when my screen was off and turning it back on when the phone woke up. Since I wasn't necessarily using 3G every time I woke up my phone, I got into the habit of just turning 3G off and on only when I need it and stay on Wi-Fi as much as possible. After uninstalling Juice Defender and growing accustomed to found this, my battery life has improved at least 3x and I have never looked back. Just my 2¢.

Yep, I also stopped using JD a long time ago. There are much better ways of saving battery than adding one more application - if you know what you're doing. Using JD is less work, but it's not the best way.
If you are toggling wifi, data, gps etc by your self you dont need JD. I used it sometime but I have habit to control all toggles myself and just found JD interfering with my choice and it shows it saves some 1.8X battery but I didnt find it that much.
I have tried many of them; in my use/ my phone (Nexus S, unrooted, stock JB) is Battery Stretch far the best, really almost doubling battery life.. JD, etc did save some juice, but far less, than Battery stretch. Just my 2c.
Personally I'd call my level of use on Android to be near expert. Not really a developer here, but I'm a very proficient user.
I'd say Juice Defender is totally full of crap.
So what can it do? It turns off "3G?" I swear this misnomer came from the US or something. We somehow equate 3G with data. I thought it meant it would throttle me back to 2G while the screen was off, but all it does is turn data off. Now here's a question: What the hell is the point of a smartphone with its data off? If you like social networking, email, communication, you WANT those notifications to come through. So what does turning data off while your screen do? You might as well turn off data manually and then turn it back on when your screen is on.
Furthermore, if you're interested in saving battery, use wifi in places where data sucks. The minute you turn wifi on, data is switched off. You don't need Juice Defender to figure this one out.
I can see 2G/3G auto toggle being useful, but this can be installed separately as the 2G/3G toggle app for CyanogenMod.
You should be able to tweak your battery to max it out without the use of any 3rd party apps or rooting or anything like that. Tons of newbies install a bunch of apps and as a result here's what could be draining for example:
- Google+ instant upload
- Dropbox instant upload (wow way to duplicate Google+ and effectively double your data use and battery consumption)
- Pulse news sync
- Google currents sync
- Gtalk 24/7 push
- Google latitude
People always say turn off GPS but I ask why? Are you leaving your maps on for 10 minutes at a time? I use location services a few seconds at a time. Show up to work? Checkin at foursquare. Walk into a bar? Checkin to foursquare. About to go home? Take a look at Google Maps. All that takes 1-2 minutes tops. How much battery should that even consume? 1%? Turning off GPS means what? I consume 0.5%? Woohoo. BIG SAVINGS there bro. Furthermore you gotta remember to turn it back on if you ever want to use navigation, and if anything having GPS accuracy helps when using location services like for Foursquare of Facebook checkins. You could find that venue as one nearby rather than scrolling around trying to find it because the cell tower puts you a mile away. You save time like that too.
Screen is the big one. Autobrightness should work well on most stock ROMs and even most stable ROMs. IF you're using your phone outdoors expect that screen to drain like mad, but indoors it should be fine.
Honestly, JuiceDefender accomplishes its task by crippling your smartphone. That's not what a smartphone was built for. You should be able to use all its features and get through a day unless you're on your phone 5 hours straight surfing. Then expect it to die soon. No juicedefender will save you there.
I think the point of JD is that you don't need 3g data on all the time, you can set it to enable 3g data every min/5 mins/30 mins/hour etc for a set time, if background processes are sycn'ing (gmail, facebook, twitter etc) it will wait until the sync is done, this means its up to you when you sync data, I sync evey 15 mins and it works really well. When you switch the screen on, data is automatically enabled, i have set it to use wifi when in range, or 3g when out of range (again its automatic) JD does save you battery and it does it all on its own, millions of downloads can't be wrong

And that's exactly what Battery stretch does - with a much smaller footprint/memory/battery load than JD!
Just give it a try - I have tried all of them- and judge it for yourself
Another one to check out is 3GBattery, very basic but maybe that was the point too

Juice Defender is a fickle mistress. It does what you want, but it can get in the way. I use it when I know I'm going to be away from power most of the day and I either forgot my Sparq or it won't be practical. When properly configured Juice Defender bloody works. I usually end the day with a 2.4x boost when I use it. Normally my phone needs a pick-me-up after about 8-9 hours. With Juice Defender I had 35% left after an 18 hour day. The only difference was Juice Defender and using Screen Filter to drop the brightness. Had about 3.5 hours of screen on time.
Juice Defender's bread and butter is its data toggle tool, and there are some things to keep in mind with it to make the most of it.
When the data state on the phone goes from not connected to connected programs that can sync want to sync. This adds a lot of data use and cpu cycles. Because of this I've used the Application Specific control rather than having data toggle on at screen on/unlock. I don't want data coming on because I reply to a text. Data comes on when I call up an app that needs it, and data runs in the background for Music and Spotify only.
There's the argument of crippling a smartphone, but honestly, 99% of communications that come over the data network aren't urgent. Urgent communications are calls or texts. No power is more crippling to a smartphone than no data.
It's an absolutely fantastic app, but the memory footprint is huge! Even really fast devices like my evo lte slow down a little over time
I know I've made a few posts about this in the past, but now I've learned a few things since then.
I know the battery isn't the greatest on the infuse (no rom that I'm using atm..) but would like to get the most juice out of my device that I can. I have root access and currently use the apps "battery calibration" and "no-frills CPU control" which I set my cpu at a relatively low frequency to help keep juice.
My phone is drained throughout my day, even without use. I believe it primarily happens because my data (mobile network) consumes it. I know apps such as "juice defender" are great at reducing idle drainage because it shuts off your network connection while in idle to save battery. However, I have used this application in the past and after a few days of use, it shuts off my mobile connection altogether.
My question is, if I were to use this application again and my mobile network were to malfunction, would I be able to change my apn to regain my network connection? In the past I had to reset my phone to regain connection, which isn't really worth using if that's the only solution.
Or are there any other battery saver apps worth using??
Thanks

A bit more information is needed before a specific course of action can be recommended. How much battery life are you using in an average 24 hour period? Also, what version of Juice Defender(beta, free, plus, ultimate) are you using, and what specific settings are you utilizing. It is a very customizable program after all. You might look into Battery Indicator Pro, which estimates your total remaining battery life based on your level of usage. I would also recommend CPU spy, which, if your device is rooted, will show the percentages that your device is running at various CPU levels.
If you turn off all the locational stuff, turn off 'update my current location' in Navigator, and set your CPU gov to conservative, you might get better battery life. I've not had any lasting luck with any of the battery saving apps. In the end, I decided to buy a couple of Anker batteries from Amazon just in case I have a bad battery day... Also some of the battery saving mods work, but I'm not sure about applying them to ICS and JB ROMS. I haven't tried!
Battery life is what you make of it..
Anything running in the background will drain the battery.. email constantly checking for new messages, twitter, Facebook, GPS, WiFi if no connection is found, etc..
Anything that makes the phone process even while the screen is off is going to kill a battery..
What ROM are you using? Some ROMs have better life than others..
How much are you actually using the phone?
What's the brightness set at?
Have you tried changing the processor and slowed it down?
Lots of information that is missing is helpful..

How about putting a widget on your homescreen to toggle data on/off. Keep it on only when you need it. I go a step further, I use Tasker to automatically turn my data off every time my screen times out (because that means I’m not using it... I can restart my data later with my widget when I need it). Maybe that’s extreme, but I’m not just watching my battery.. I’m managing my limited data plan.

It may be that you have wakelocks keeping your phone awake when it’s supposed to sleep. One way to see this is (in GB or above) Settings / About-Phone / Battery Use...then click on the small graph at the top... should expand it to a large graph with traces along the bottom including Awake and Screen On. If you have long periods of time where phone is awake while screen is off, that’s a wakelock problem. A good program to troubleshoot that is Better Battery Stats. If nothing else, follow the instructions in the first post in the BBS thread linked below, and then post a dump to the end of that BBS thread (the developer and a lot of other knowledgeable people follow that thread and will help you interpret results):
http://forum.xda-developers.com/showthread.php?t=1179809
Thru use of BBS, I found that Google Maps is one that was keeping mine awake and I think someone else on the forum reported the same. If that program (Maps) is causing problems, you can disable it from auto-starting on boot using Gemini Manager. It will still be available when you need it, just take a few seconds longer to load the first time after boot. Then need to reboot to stop it from causing wakelocks after use (there may be other easier ways, but this works for me).
Another program (Power Tutor) was helpful to me to see programs that were consuming unusual amount of battery although not necessarily thru wakelocks. In my case Dolphin Browser HD was occasionally drawing very high power even when that program was not actively in use.

So how can I stop maps to running in background? only rebooting the device is the only option?or is there any other option?

Just to provide more details on my previous post (not sure if it's answering your question):
I followed instructions here:
http://forum.xda-developers.com/showpost.php?p=29420959&postcount=7059
In particular, I installed the free program "Gemini Apps Manager". That allows you to stop programs from auto-loading at boot.
So I used the program to stopp Google Maps from auto-loading at boot.
That stopped a large chunk of my wakelocks, as long as I don't manually launch Google Maps.
If I do manually Google Maps, then those wakelocks come back, and to get rid of them I have to reboot.
I don't use Maps that often (only when I go on trips), so it's not a big problem for me to reboot when I'm finished with my trip to help keep my battery use low.
It may also be possible to kill it from the list of applications at Settings/Applications/ManageApplications and killing botht the application and the process...but I'm not sure if it will stay killed that way... haven't tried. I know some applications have hooks that make it hard to get rid of them once they're launched.
But (if you haven't already), I think it's a good idea to use BBS to find out what programs are causing problems on your phone. You may have other apps causing lot bigger problems than Maps. And it certainly may be the case that a program that acts up on one phone can be fine on another phone due to differences in the way the user configures the application settings and the phone settings (along with other possible differences in application version, ROM used, etc etc).

Thanks for your detail explanation. My main question was how can close the app without restarting? i feel my major battery drain is from dolphin browser, befor dolphin i used opera, even that has the same problem. Most of the time, if I dont open dolphin, my phone battery is good, but once I open it, it drains battery. So i am looking for soemthing simple which does, without rebooting the device.
Any way thanks for your help.
I have noticed that even though I keep my Wi-Fi off 80% of the time, when I look at the built in "battery app" (whatever you wanna call it) it shows a blue bar all the way across for WiFi, which I believe means it's always on.
Also, sometimes WiFi usage will show up on the list of things eating the battery, and it will show that it's on the entire duration the phone has been turned on ,even though it shows off in settings.
Anyone else have this issue?

* Often when I work the mobile is at my desk but I still comunicate by sending SMS and using Whatsapp in my webbrowser. Works fine with Samsung and Huawei but with my new Mi10 Ultra id does not work. Connection is lost and I have to tuch some key on the phone to light up the screen and then it syncronizes.
I have set permissions for the apps to allow both autostart and not affected by the battery saver in the system.
I have also set the "data usage" for the apps to allow background data.

Has anyone run into this problem? Is there any general (mayor) switch for this that I have missed?
This happens to me with Gmail. Sometimes they come in on the lockscreen and sometimes I have to turn the phone on for them to appear. I still have this problem on my Samsung S20 Ultra but I learned to live with it since I never figured out what the problem was. I have no such problems with my SMS or WhatsApp though. Everything else for me seems to be coming through.

Hi there. I pretty much have the same problem with this phone. If it's not permissions nor background data, it's the power saving feature, which is the most aggressive I've seen yet.
I was talking with someone about this in another thread, but I was instructed to turn off battery saver. It got better for a day, but it kind of returned back the way it was. I think you could try and play around with the power saving settings for the apps you want immediate notifications from, which I haven't had time to do. Please let me know how it goes for you and I'll find time to play with it this weekend.
