Need app to disable APN/save battery - Desire General

I really like the idea of disabling the phone's APNs when it's just sitting idle to save battery. Unfortunately I've not found an app that can do this reliably.
I first tried Juice Defender/Ultimate Juice which is so configurable that I thought I'd hit a winner. It's (supposed) ability to automatically enable the APN for a short period every so often seemed like the perfect balance of powersaving/data syncing.
Unfortunately it didn't work out this way and messed up my APNs and internet access completely, even after uninstalling (until after a few reboots).
I tried Sleepy Battery just today. Again, the app didn't work as promised - it didn't re-enable the APN after the phone woke up, leaving me with no internet. Again, this app had made a change to my APN that I had to go back in and correct, after I had uninstalled it.
Has anyone got any advice, or can recommend an app that actually works for this use?

I personally use use APNdroid, it allows to switch 3g on and off and has a widget with it. It doesn't automatically turn the 3g on or off depending on your use, that's something you'd have to do yourself...
Hope that helps!

Try sleepy battery, juice defender, or another app I think it's called sweet dreams.

Thats really strange, I've had great results from JuiceDefender/UltimateJuice. It turns APNs off when in standby and turns them on for 15 seconds every 5mins to allow everything to sync. Really can't fault it.
I'd maybe suggest giving it another go? I believe there's an update coming soon from the developer to sort out some issues with the Desire. This might solve your issue.
Not come across any other app's that do what JuiceDefender does as well as it does.

I really wanted to like Juice Defender. Hopefully the update will help, so I'll wait a while for that.
In the meantime I'll give APNDroid and Sweet Dreams a try. Thanks guys

I would recommend getting the juicedefender and ultimatejuice is well worth the purchase! juiceplotter is also a great free add on. They will save you on battery and will automatically control your apn and wifi.

Just a quick question on JuiceDefender actually. I just bought UltimateJuice to try, love all the options it gives you. But, my question is this...
I have my apps (Facebook and the likes) set to sync once every 2 hours. I also have UltimateJuice set up to turn APN on once every 2 hours to allow syncing. Will these two points in time automatically sync up with each other? I can just see Facebook trying to update at 14:00, 16:00, 18:00 etc while UltimateJuice turns APN on at 15:00, 17:00, 19:00 etc.
Hopefully not though. Anybody know? Thanks.

I have wondered this, I if you've only got APN turning on every 2 hours you might as well set Facebook to sync every 2-3minutes because, my guess is that it won't attempt to sync if there is no data connection.

Hmm, possibly. I've set Juice to turn data on once an hour. I'll leave it like that for tomorrow and see how it goes. It currently claims to be extending my batter life by 1.88x, and if that remains consistent and it actually can do that then I'll be very impressed.

I've now tried APNDroid and I have to admit it seems like it does save some juice. But I forget to turn it off/enable my APNs frequently, and therefore don't get my data coming through for long periods. I need an automatic app.
Sweets Dreams does not fit the usage I want the app for.
So have gone back and tried Juice Defender again for today, and it seems to be working ok this time round. However it reports that it's multiplied my battery life by 1.95, but that is a complete load of rubbish. My phone was unplugged literally 12hrs ago, and I'm now down to 14% battery.
My use of the phone isn't excessive - searched the Market for maybe 5-10min, installed 3 apps, and uninstalled about 4 apps. Browsed internet for maybe 15min total. Sent and received 12 text messages each way. A few emails have come in that I've dealt with. No gaming action at all, no calls, wifi is completely disabled, I had just a couple of widgets updating infrequently (every few hrs) but I got rid of them early this evening.
What do I have to do to get some sort of half-decent battery life out of this thing?

sometimes u want to have data syncs when the phone sleeps, for example twitter if you have new mentions. I used quick settings (http://www.appbrain.com/app/com.bwx.bequick)
long press on the search button brings this up so you can change it quick.
You could change the sync frequencies to longer gap inbetween updates to improve battery life. I turn on my APN the entire day and I still get about avg 14hrs of usage

I use Data on Demand from the market. It's simples! Just turns data off when the phone is asleep. Doubles the battery life!

I like it! simples indeed!

I use juice defender/ultimate. It works incredibly well and I can now easily get 2 days use. I have a rooted Desire with MCRr3.
Without this software I stuggled to get 1 day.

After my first couple of days with UltimateJuice I must say I'm pretty impressed. Syncing seems to work fine with the schedule I have set up. I have it turning APS off at night, having it on when I have the screen turned on, and off when the screen is off and then turning back on to sync everything once an hour. Greatly improved battery life so far.

Doubled battery life - but there's a down side

there is a setting under settings / wireless and networks / mobile networks that says "enable always on mobile data"
Switching this to off about doubled my battery life and everything still seemed to work okay as far as data goes. All my apps worked including things that check or update periodically in the background - so I'm not sure what this feature does.
The only downside is that the phone would crash periodically in areas with poor reception. It would go back to the sprint boot animation and come up after a minute and the uptime would not be reset.
Imconvinced part of the battery life problem is due ton inefficient use of data, but I'm wondering what can be done about it without sacrificing stability. Ahylne else have a similar experience or willing to try it out or have more information?
Trying this out, seeing what it effects it has on my normally used apps. So far (first 20 minutes of doing it) everything seems to run fine. I would guess this causes the phone to "hibernate" the 3g radio whilst locked.
I started doing this on Hero and continue to do it on the Evo. The biggest issue is that if you are using pandora (or similar app), it causes problems when the phone goes to sleep.
The setting stops your 3g connection when the screen goes to sleep. This prevents the phone from updating email, twitter or whatever else you use. As soon as you turn the screen on, it turns on 3g, downloads your email etc.
I check my phone often enough (for the time or whatever) that I don't mind not getting my email immediately (it downloads when I turn the screen on).
This has saves a ton of battery life. The only time I enable always on mobile network is to listen to pandora. I have done this since day 1 and have had no issues.
I tried this last week and it made a massive difference in battery life. I turned it back on though because I do like my phone to download things while it is idle. I also don't want to get used to the improved battery life just to have to switch it back later.
i dont know if any of you have heard of juice defender what it does the same thing pretty much. with a few exceptions. whereby you can set the program up to allow your phone to take data even if your screen is off at a certain duration of time, then it will go back to sleep.
thats a really simple explanation of what the app does. if anyone of you does decide to use the app let me know i can share my settings more specifically. I have increases my battery life by 87% and i have have 0 problems.
I have this option unchecked and not only has my battery life improved, but I don't notice any performance or stability issues.
Also, my data continues to download in the background as normal (regardless of whether the screen is on or off). I have Facebook and Twitter set to download data every so often and it continues to do so. Even Google Voice will notify me of messages even if the screen is off.
I think what this option does is, when checked, makes the radio work hard to find and keep a data connection (especially in low signal areas). I notice that with the option unchecked, my data connection drops a bit more often than with it on. I don't mind that though seeing that the data connection simply reconnects automatically and almost instantly.
thanks!

Would you all mind doing an experiment for me? Turn this option off (so data is not constantly on) and turn your screen on and put it in your microwave so it loses signal*.
Watch it and see if it crashes. I suspect something about this setting being off is causing the phone to crash when it loses its cell connection momentarily.
*Don't turn on your microwave.
Okay so after more research I'm pretty sure the main instigator of poor battery life is the data connection constantly going wild. According to SystemPanel my phone hangs out doing nothing downloading at 100-200Kbps for large amounts of time. Not sure what it's downloading.
To find out what apps were causing this I used Spare Parts and saw this:
Click for full size
So a process with the PID of "0" is what is using most of the data connection, followed by UID 10011 which is contact/calendar/mail sync. I can click through to 10011 and get details, but if I try to click on PID "0" I get a force close.
There is also another preference under Accounts & Sync for "background data" and "auto-sync." I'm not sure what the difference is between this background data setting and the one in wireless & networks that says "enable always-on mobile data." Anyone have any thoughts on that?
Also interesting is what was happening when I had always on data disabled:
Click for full size
You can see where my phone was crashing but look at my battery life before and after the crash. It looks like it has dipped significantly. Also, the crashes only lasted a minute while the phone rebooted, not nearly as long as what was recorded here - so it's possible something was going on with the battery life before the phone crashed.

I swore Juice Defender only works with GSM and not CDMA.
It even say this when you go to download the app. Although I did just google it an apparently people have it going on the Motorola Droid rooted.
Who with Android experience wants to prove this?

+1 I thought this was the case too. i unchecked the data option. It's been a full day and no reboots
I'm running Juice Defender today and my battery life seems even worse. I'm talking 20-25% drop per hour.
SOMETHING is wrong here.

The option is not meant to enable/disable applications from using the data connection when the screen is off, so applications should be able to continue updating.
What the option is meant to do is to determine whether your phone should maintain data connectivity all the time, even when there are no apps using data. Unchecking the option means that when an app needs data, it must first connect, then make its request. This makes it take a little longer (or maybe a lot longer for 4G which seems to take longer to initialize a connection).

[Q] Battery starts draining at exactly 5am.

I started using JuicePlotter yesterday, and noticed that at night my battery barely drains, if at all (hooray for setcpu!). Until exactly 5am when it starts draining heavily at a steady rate. I've done all of the obvious stuff (I think), like making sure I have nothing set to begin syncing at that time, but I can't seem to pin it down.
Does anyone know of a way to find out what's turning on at 5am and draining the battery?
Do you have an Exchange sync setup?
If you do you may want to check and see if your Peak times start at 5AM. If so you may want to set it to update less frequently.
Does JuiceDefender run on a schedule and keep 3G off until 5am?
Thanks for the suggestions guys
I have exchange set up, but its set to "as items arrive" for both peak and non-peak hours (which is set to 8am anyway - yeah, being on call 24/7 sucks).
I'm also not using any kind of timing app like juice defender to schedule anything.
One wierd thing I noticed that may be tied to this, is that certain apps like twitdroyd and fb update immediately when I open the apps, even though they're set to refresh manually, and not to update when I open the apps. Still trying to figure that one out.
Night mode is enabled from 2 am to 5 am. Depending on your settings, Data/3G/Wifi are disabled between those times.

He is referring to JuiceDefender, I bet. I would guess a lot of people who use JuicePlotter also use JuiceDefender. It does exactly as he described: turns data off from 2am to 5am. I use it, and it does help. It also keeps data off when the screen is off during the rest of the day, except for a quick check every so often.

rats - I was hoping he was referring to something in regular settings. I'm not using JuiceDefender, or anything similar.
well if you do have it setup for everything to be off between 2 - 5 then wouldn't that make sense that as soon as 5 hit your apps will start syncing even Google apps as they have been trying to sync that whole time and just started queuing up and finally your radios turned back on. I have not used juice yet so i do not know much about it just throwing in some pennies.
One other thing the refresh manually is only for when the app is closed as soon as that app opens its going to sync with its servers. When you set it to manual then that means when you open the app you manually refreshed it and the phone did not do that while idle or you were busy on some other app. Its like twitter for desktops if you set your refresh manually then while the app is open it will not refresh until you hit refresh

One thought: Do you have a good signal in the spot where your phone sits at 5am? A bad signal is the best way to drain a battery fast. A friend's house has an awful Sprint signal, and my battery will drain in four or five hours there, even with no use, whereas I get well over 24 hours with average use in good signal strength areas.
Back when I first got my phone, I used System Panel to figure out what was causing the battery drain. I liked using it so much, I even ended up purchasing it. The history part is what you want, and it will work without paying for a bit, so you can find the problem.

that would make sense if I was running something like that, but I'm not - as a part of my job, I need to be able to reply immediately to specific emails. At any hour. Total PITA, but hell, it's better than not having a job, right? JuicePlotter's pretty neat though - it just sits in the background monitoring your battery levels and graphs them. For example, it was showing an almost horizontal line from when I stopped using the phone the night before until exactly 5am when it started a gradual decline.

Are you sure about this? I mean it makes sense, but I would be willing to swear that back when I was running stock I would open FB or Twitdroyd and it would wait for me to hit refresh before syncing with their servers. Twitdroyd, for example, I would set to keep 80 tweets, and I would check it only occasionally, so I could read those 80 tweets whenever I wanted. Now when I check it, because it syncs immediately, I lose anything older than the most recent 80 tweets. As a workaround, I've increased the number of tweets to keep, but it's still annoying.
ok so hmm what rom are you using. not wanting to bash the dev but could it be that rom?

My signal's not great, but the phone didn't move between 4am and 5am, and the battery only started draining at 5am.

I actually purchased SystemPanel this morning with the hope that it would help me get to the bottom of this (I had been using the free version for a while, and now I had an excuse to buy it). It shows me history of battery, device usage, and cpu activity, but even if I see that the cpu or the device is being used, I'm still not sure how that's going to help me pinpoint what's going on. First I need to build up some history anyway though.

[Q] SetCPU and JuiceDefender, are they needed anymore?

Hello,
Title says it all...
I would notice overnight that my battery would be completely horizontal (no drop) and thought it was the combination of SETCPU and JuiceDefender (night profile + screen off drop mhz).
But, after unisntalling them, I noticed the same "flat line" at night and also achieved over 30 hours of battery life.
My question is... do these apps really make a difference on our phones?
Or, are the phones advanced enough to handle everything just fine?
your thoughts are appreciated.
I agree... I got about 27 hours of life out of my battery without set cpu or JD (i've never liked JD anyway because its like putting my kid on riddlin)

Which version of JD are you using? If you have the Plus or Ultimate version, you can probably still gain some benefit, but you need to learn how to custom configure the settings so that you use the ones that are still relevant. For example:
Where Not Helpful: JD will turn off your GPS if an application isn't using it, but most of today's phones will do that anyway.
Where Helpful:: In advanced settings, you can provide a 'night schedule', wherein during this time, JD will disable mobile data, and thus polling, so your phone will not go out and check for mail, FB messages, Tweets, etc. Otherwise, mobile data is off unless you 'wake' the screen for some reason. Or another feature that 'trains' your wi-fi to only activate when you are at home or a 'recognized' wi-fi spot. These are a couple examples, there are others.
Where it MAY be Helpful: JD can disable mobile data for a custom # of minutes (10/15/30/60) and prevent background sync during those periods. It will awake, allow the sync, then turn mobile data off. Now some apps may only sync in these intervals anyway, but unless they're all syncing at the same time, you could have lots of 'up' time. Some of this may not 'wake' your phone from Deep Sleep, but depending on how sloppy the code is, it might.
Hope this helps.

I think really depends on the ROM you are running. ViperROM has a script that changes the CPU speed and governer on the fly. So no need for SetCPU there. I'd say Juice Defender can still come in handy with turning data off when you aren't using it.
My 2 cents. Your results may vary.

I use ultimate. I did run a night schedule, but that kind of points back to my original observation... I'd have night setup from 11pm - 7am and see a horizontal line for battery during this time (wow JD is really working)... BUT, with it uninstalled, during the same period of time 11pm - 7am my battery was also horizontal line... So did it really do anything? I'm on wifi at my house so when I'm sleeping the phone is wifi and not constantly pinging the mobile network (does that make a diff. being on wifi)?
I also did like the wifi only when home setting.
With ViperRom, I probably don't need set CPU anymore... Maybe i'll throw JD back on.
One question.. were you running the beta JD? I noticed the beta would always throw errors in the log stating i needed to uninstall, reboot, reinstall (I never did) anyone else have that happen?
These numbers sound like you have the radio off and don't turn your display on. Pretty amazing numbers otherwise. Would love to know the rom + kernal you're using
edit: I see the post above you mention viperrom. Typically if you have data turned off and display off any device will last days. My OG evo lasts for around 48 hours just sitting there. Still really impressive if you're using your phone within that 30 hours

I've never tried the beta; I started with standard, upgraded to Premium, then eventually upgraded to Ultimate (I use the 'Customize' setting, but rarely the 'Advanced' config).
I hear ya on the night-time wi-fi thing. But with this particular phone (and before I rooted and changed ROM/Kernel), on some nights I would be connected to wi-fi and get ZERO CPU sleep time, other nights it would sleep - I have no idea why. It is conceivable that if the only polling your doing is e.g., Gmail, that either it doesn't happen at night, or it happens in such a way as to not knock the phone out of sleep (it IS Google's OS after all).
On a related note, I'm using K-9 mail (my primary mail is Yahoo); it throws wake-locks all the time (set to poll every 15 minutes), but they don't seem to impact battery life or take the device out of deep sleep which is why I suggested that case above.
One other item I like about JD is the ability to permission each and every app for wireless/network access; obviously mail, calendar, phone, etc. need it, but some apps simply don't, and I've been surprised when I set it to 'notify' and some random game pops up seeking network access. Looking for an update? who knows, but I lock 'em down anyway.

I do not turn off data/radio (no airplane mode).
I'm running ViperRom 2.2 with the latest loskernal experimental.
My display was on for roughly 2 hours (again, just used it as i happened to during the course of the day) and data was on.

Interesting thing is with the latest JD build it has the bluetooth settings, so i can leave my headset paired, but the phone disconnects while not on a call and then when i get a call, it turns on... kinda cool.
In regards to the permissions... do i need to give the email applications permission for enable/screen off? (so that I'll still get the notifs?) or just enable (as in when screen on).
thanks,
RR

Removing Bloatware aka "what can I do to get better battery life?"

So I think by now everyone has realized the battery life on our A100's is mediocre. I've actually been pretty content with the usage I get out of mine. What I'm not so thrilled about though is the idle usage. I'll leave for work in the morning with my A100 at / above 90% battery and come home after 6pm with it completely dead. I have wifi set to turn off when the screen does, any app I have that has a sync option is set to 6+ hours, and I've stopped using live wallpapers. Every other electronic device I have can usually last a full day when not in use(my old netbook gets 3 hours of use on battery but 2 days while sleeping).
I've started looking into the "bloat" / OEM apps installed by Acer. Nidus, sync, socialjogger etc... My main questions are; what can be removed, what can I live without or would be better of with a 3rd party app, and which Acer apps can possibly be causing the idle/sleep battery drain? This thing should still last a full day while sleeping, shouldn't it?
Any suggestions? Anyone else have this issue? Thanks!
You could try using Bloat Freezer to freeze apps. I have alot of the acer stuff frozen, and with it in standby, easily goes a day. Things like socialjogger, acer init, etc.
These are the apps I've completely removed from system apps, made a backup of course..
AcerClockwidget.apk&odex
Agendawidget.apk&odex
Aupeo.apk
Clearfi.apk
DTG.apk
LinkToFacebook.apk&odex
MusicA.apk&odex
MyLocationWidget.apk&odex
NemoPlayer.apk
Planner.apk
SocialJogger.apk
Solitaire.apk
Xt9.apk
You can also remove appinapp butyou will loose the games multimedia app I use that so kept it.
Battery life hasn't been that bad on mine. I expected worse, I just picked mine up last week and after reading reading reviews I expected worse.

WOW! I can use mine all off and on all day and don't have a problem. There has got to be an app that you are using that is destroying your battery when idle. If I don't use my tablet all day, it will last 2 full days (with wifi kept on).
That's what I was thinking. I get a decent amount of usage from it; it's when I'm not using it is when I feel like it drains the most.
I started freezing apps last night and let it charge overnight. I've still got to go through my apps and remove a few I don't use, and check to make sure they're not syncing too often. Do you all leave your gps and wifi on all of the time or have them shut off while the tablet sleeps?

My settings are to never turn WiFi off and I always leave sync on; I like getting notifications and app updates. I have a weather app that updates every hour and Pulse news that updates every 4 hours.
I also always leave my GPS on, but there aren't many apps that use it while it is not in focus, so I rarely ever see GPS pop up on my battery usage list.
I do not use a live wallpaper.
I found that with wifi on, my tablet drains about 1.5% per hour when idle.

I suggest other than setting wifi to turn off when screen is off is to use a wifi toggle widget. You really never know what happens when the screen is off if your wifi is really turning off. Wish it was built in to the quick launch though like some Honeycomb tablet.
You can also use setcpu to setup profiles so that when the screen is off the processor stays at a slower speed rather than jumping into high gear when something wakes it up to sync. I've been able to go days without having to recharge (but I only use it for reading books, listening to the music I have on google music and play order and chaos every once in a while). I havn't touched my a100 in about 4 days and its sitting at 62% battery power.

here is my usage, I never turn off wifi no profiles
I don't necessarily think you need to remove any of the stock app. My wifi is set to turn off when screen is off, GPS off unless I need it (apps like facebook will use it when you open it since it tries to get your location for checking in even if you're not checking in). Gmail is left at default but other mail is set to never (I just manually sync it when I open it).
If you wanna go a step further, you can install a wifi on/off widget to completely turn it off just incase an app is trying to use wifi.
With my setting my battery drains about 1-1.5% an hour when screen is off. IMO the screen is what uses the most battery. However though after conditioning the battery for 3 cycles it's been lasting longer.
I was just about ready to return / exchange my a100 so I did a factory reset on it. Lost track of time and forgot to, so I just decided to boot it back up and play with it. Left it alone at around 70% yesterday afternoon, came back home at 7pm today and to my surprise it was at 40% battery remaining. Must've been an app or setting I had that was killing it.
Probably end up hanging onto this awhile longer. Great tablet for the money!

Also can freezing apps brick your tab as well? Or does it defrost itself after boot?

I think with the 1gb ram on our device there shouldnt be a need to freeze any app and it doesnt defrost itself on reboot. Atleast it shouldnt.
Also I found for the most part if an app can be deleted it will let you delete it by dragging the app icon in the upper right in the app drawer. This is probably the safest way to delete rather than doing it in root explorer or TU.
This might be a dumb question but is it possible you have wifi issue that i've had on 2 a100s which will prob cause it to use more battery as its trying to work harder locking on.
It seems for the moment my battery issue was resolved with a factory reset. I have nearly the same apps on it now as before and my a100 hasn't been dying overnight. Don't believe I've frozen anything this time around either.
I don't think ram has a whole lot to do with it. I just figured some of these apps were starting themselves or syncing often, causing the battery drain.

Do you have a lot of widgets that requires syncing like youtube, twitter, weather, facebook? Those are the apps you probably what to check. OR you can just turn off wifi if youre not surfing or streaming.
Here's mine with wifi turned off. It was at 89 but I had to turn on wifi so I can find a screen capture app in the market. I have lots of apps including facebook, twitter, weather widget, which cant sync cause the wifi is off. Have not removed any stock app. I know this doesn't really answer what you asked but I'm just thinking something else might be wrong other than apps. Maybe its your battery not holding correct charge. Have you tried calibrating the battery?
I tried calibrating the battery the first time around. This time (after the reset) I haven't done anything special and have so far been getting 2 days of idle/light use before needing a charge. Satisfied so far. I was mainly concerned that I wouldn't be able to go on a trip without it needing a charge while sitting in my bag for a day without use.

best setting for juice defender?

just got juice defender ultimate, as it seems to do a good job of making my battery last longer....but there are so many settings, i'm getting confused.
I basicaly just want the best settings that will disable all internet to save battery, except for once every hour when my i want the phone to run the "autosync" process to sync my facebook, twitter, emails etc. i alsao want it to obviously allow me to connect to the internet if i manually start an app which needs it (internet browser, facebook app, peep, etc).
at first, the app seemed to be doing this, but now i'm finding that although it's doing a great job of saving battery, it's not syncing, and my internet connection doesn't come on when i open an app. (or occasionally, it will come on, then not turn off again until i manually tell it to.....which defeats the whole point of having jhuice defender...i got it so that the phone would automate this process).
any help greatly appreciated...
totally given up on these battery saving apps now. they all seem to do the same thing...
they work exactly as they should for a couple of hours (i.e. they cut out internet except when syncing or when needed for an app etc)...then they suddenly jsut stop working, cause my internet connection to be lost completely, and i can't get it back until I reboot my phone (losing temp root i might add, so having to go through that whole process again too).
i think i'm going to just suck it up and charge the thing every day...i bought an "extended battery" which is supposedly 2430mah (around twice the stock battery), but it doesn't seem to give twice as much performance....it just seems to slow down the battery drain slightly for the first half of the cycle....
i.e. it lasts for around 2 hours without going below 90%, then within the next 2 hours it will drop to 70%, within the next 2 hours to 50%, the next to around 20%, then finally dying within the next 2.....
this is with syncing on, occcasional text or email checking etc.
so i'm getting around 10 hours use instead of around 7 or 8. it's better, but it's far from being twice the capacity.
but anyways, yeh, battery saving apps jsut seem to kill my internet requiring reboot, so i'm gonna just manually cut internet at various stages through the day from now on, and keep charging every night? sound like a plan?
Green Power Premium.
Simple and works as advertised...Juice Defender has got a lot of settings for sure...

ok, i'll give the free version a try...but i'm not holding out much hope, i've tried so many of these battery saver apps now, they al result in my internet connection being totally screwed up until i reboot the phone.
The default settings are pretty good. I don't think I changed much in the way of settings. Your phone will save a lot of power throughout the night with this.
thanks! finally, a battery saver that actually works!
been trialing this today and so far so good.
7 and a half hour shift at work today, it's been syncing every hour (which i know has been working, cos on my break i had tweets and emails waiting, and again when me shift ended)...sent a few texts in the morning, on lunch and after work too. so far it's down to around 83% battery....
The important thing is that it hasn't destroyed my internet connection (touch wood). It switches it off until i unlock the screen, except when it periodically turns on to allow the syncing. It also knows when I am at home and will use my wifi instead of mobile internet.
I'm going to keep trialing it for a few days to make sure it definately doesn't crash my internet after a while like the other programs seem to. So far so good though. If it keeps working, i'll buy premium for the night mode feature. Save even more battery that way.
thanks again, very happy
No problem. Glad it worked out for you.
Green Power is no longer working at night mode....switching WiFi and mobile networks works still, but it doesn't seem able to switch to airplane mode. This is only since I rooted, but I'm on stock Rom and this appears to be the only problem now.
::EDIT::
apparently, someone else on their forums have the same issue, and it's a known bug, something to do with green power being "paused" then "resumed". weird how it's never done it before though :s
have uninstalled it and reinstalled, so hopefully that will sort it out :S
::EDIT::
worked perfectly last night, so it must have been a one off glitch :s
