Auto send/receive while in sleep mode?

Is it just me or can this phone not do it?
On my iphone if I leave wifi on and turn the screen off, it will connect only when needed using the auto send/receive schedule.
My xperia no matter what i do just wont seem to send receive with auto send/receive set to 5 minutes, wifi enabled, and i turn screen off with power button (or even leave it automatic).
Does it work for anyone else or is this just the way the xperia works? It only sends/receives when it's awake, in which case, pretty stupid,cause i can just do it manually if i'm using it.

I think winmo only sends/receives over a cellular connection while the phone is asleep. Wifi on the other hand is disabled when the phone goes asleep in order to preserve battery life....so no sending or recieving emails over wifi with the device in sleep mode

That's really disappointing, it's a feature I had come to expect, thinking the device could atleast witch it on long enough to sync my email just like the iphone does before switching it off again.
guess my only option is to buy a data plan.

Try Advance config
Bottom right softkey "Menu" --> More Settings --> Connections --> Enable Wi-fi on standby mode

Thanks, I have just tried this, but I see that basically what it does is prevent the wifi from sleeping on standby mode, which is going to kill the wifi I presume in a couple of hours.
I guess it's just not possible for it to do what exactly I wanted it to do which is to connect and disconnect when required, to send and receive, while left switched on and the phone is in standby.

I believe that even when the phone is on and wifi is on I think the normal wifi power save (middle slider position) switches itself off after an idle period to save power when not in use, "on" just means available for use, not necessarily powered up.

I need this too, could someone try a mort-script or something to connect to WiFi automatically and then send/receive emails every desired set hours? Think it is possible..

Well
I tried enabling this (and yes, the wifi stays on while asleep) and putting my power save slider all the way to the right, however, after waiting the set time for my auto send/receive (5 minutes) and infact more, it did not send/receive until the moment I woke it, so I don't know if it was just about to do it, or if waking it caused the update.
i will give it another go and see how it goes, if you say that the wifi does infact just sleep itself when idle it shouldn't harm the battery life too much.

Strange
Ok, after further experimentation, I got it to send/receive my email while sleeping with the mode set for standby wifi enabled, however, with the refresh time setto 5 minutes, it took almost 15 minutes to update.
15 minutes is about the time I want, but will it take more power if I leave it on 5 minutes, or will it take even longer still if i set it to 15 minutes?
I'll try leaving my wifi on for a couple of days and see how it goes.

Try the program rk-OSR. It can connect/disconnect wi-fi automatically only for synchronizing e-mail.

Thanks

Thanks, I'm going to see how it fairs over the next couple of days with the wifi set to work during standby (in terms of battery life) and if that doesn't work out i'll take a look at the app.
I don't know what it is but i just have a phobia of running extra 3rd party software on a phone that can only just about handle itself.

You pretty much have to run 3rd party apps on WinMo. In my opinion it's like using a normal computer with windows without installing any other applications. It's barely usable for anything at all without getting really annoyed.

Yeh, but what annoys me is that my desktop computer is designed with the hardware to run its OS and a hell of a lot more, the hardware in this thing barely runs the naked OS, so I'm reluctant to add any more.
Anyway, after experiments it's been pretty much a total failure with the sleep wifi thing.
Looks like that 3rd party app will be my last resort, lets just hope it's unobtrusive and has litttle battery drain (aside from the obvious).
Failing that, it's either keep lugging around an iphone or get a data plan. Might sell the iphone to fund it.

You can't seriously consider using the iPhone for this. It's a toy.
I'm sure you'll be happy with rk-OSR.

You;re right, iPhone is a toy, but considering the problems I'm now having downloading email attachments (mp3) and the fact that it doesnt check my mail properly while sleeping, it seems almost worth carrying just to make sure I get my email without having to actively check for it.
I'll take your word though and try rk-OSR and hopefully find a solution to my attachment problem, then I'm a happy happy xperia owner in heaven.

Ok...but.
Ok, got rk-OSR installed and it is working perfectly if I use the "test" button. However, I put the device to sleep, set to sync in a couple of minutes, wait 5 or 6, wake it up myself and nothing. Even the log doesnt have anything after my test attempt. What could be the problem?

still wondering how to get the phone to do this... is it not possible for the phone to check emails while it's in your pocket? such a simple concept yet...

alias_neo and dinan, I found a solution!!! All you have to do is to install GProfile and this program called rk-OSR. You create a time-based profile (in GProfile) and choose a specific time (eg: 1am) to run rk-OSR. You don´t have to select anything else (wifi toggle, etc). Then you select the same time in rk-OSR (1 am) and in this program you select the wifi options. It worked for me.
Hope it helps you

[Q] Cell Standby is killing me...

Lately my battery has been draining at crazy rate with minimum options/services turned on.
Wifi on, brightness on automatic, and the rest turned off (sync,BT, mobile data, GPS etc)
It seems as though its to do with the radio. Under battery use, cell standby is always >60% and apparently my time without a signal is always >50 also. The thing is, I get full reception at my house, full bars and no patchy signal.
My guess is that something is killing my signal when the screen is off. I'll go to bed with 100% battery and wake up ~7 hours later with 65%. For a brief 10 seconds after waking the phone, I will have no reception. It either restores itself or I have to go in and our of airplane mode.
I'm running CM6.1 final with pershoots 1030 kernel, if that helps.
At first I thought SetCpu wasn't giving the phone enough juice to keep the radio going when the screen was off. I had a profile to max at 384mhz(for screen off) and thought it was the problem. I disabled it and deleted it, but no luck.
I am strongly hoping that others have been in the same situation and found an easy fix. Oh, and I've already tried wiping, no use. I've also tried GSM auto and WCDMA preferred, neither any different.

Did you try reflashing the radio?

No I haven't, is that Known fix?
I've only reflashed the ROM, twice.
By the way, I used the airplane mode trick to stop that common cell standby abnormality in the battery use settings. Its still draining rediculously quick when the screen is off.

There is nothing common in your problem, so it's not a common fix. It's just something that might help - since the drain is attributed to the radio, trying to update radio SW makes sense.

It *may* also be worth playing around with *#*#4636#*#* menu a bit to change your preferred network type. I have read elsewhere that some of the other options (GSM auto (PRL), for instance) could help your phone conserve battery while it's idling.
Access the menu by opening the phone app and dialing "*#*#4636#*#*" ( that's *#*#INFO#*#*, btw ), and then select the "Phone info" menu.

Which radio version are you running?

Install aLogcat to see radio buffer ( Preferences --> Buffer?), it might give us some clue about your problem...

Thanks, I've tried fiddling with those settings already. GSMauto made a little difference but nothing significant.

[GUIDE] Optimizing battery life of your P990

This is a guide of how I have managed to massively extend my battery-life on the Optimus 2x. I personally use instant messaging like whatsapp and talk, and everybody should where possible, so I don't believe in turning off data during the day to save battery (sms is so 1999)! This are my recommendations to tune your battery-life from unacceptable to at least acceptable times (1 workday with quite high usage).
Items found to work especially well on the Optimus 2x P990
Use WiFi whenever you can, but disable when there are no networks you can join
- 3G seems to be by far the biggest drainer of battery-life, and WiFi idle seems to consume very, very little power. Make sure WiFi is *not* disabled when the screen turns off. Make sure to switch it off when you're not able to use a WiFi network however, to stop it scanning.
Set Network-Type to GSM (auto)
- Use the default dialer and select *#*#4636#*#*, select phone information and select GSM auto (PRL). Still allows for hsdpa data, not the maximum highest speed, but still quick enough for usage and extend battery life of some networks massively. If you want to be even more agressive, turn it to 2g only, but I find this too slow for casual surfing or internet usage, but if you only need it for instant messaging it should be good enough.
Disable gestures and orientation sensing
- Disable the specific gestures in the gestures menu and disable orientation by the button on the notification bar. Spare parts detects minutes of activity of the sensors during normal usage where it's not actually needed, so simply disable it when not using it from the notification bar (which is easy to do without switching apps anyway).
Make ABSOLUTELY sure your RIL matches your baseband
This is crucial. Without a matching RIL file (lge-ril.so in /system/lib) is ok, otherwise you will have a massive drain and problems with networks disconnecting all the time. Use LG GetRIl in the market to fix this if you cannot do it manually.
Check if your MicroSD card is detected when installed!
- I have issues sometimes with my MicroSD card being plugged in but not deteced, which causes my MicroSD card to become very hot, and my battery to empty in 3/4 hours completely. Reboot or remove and reinstall when it happens. Generally try to keep your phone keep as cool as possible, hot temperatures will decrease your battery-life.
Conventional and standard items for Android phones:
Check partial-wake usage in Spare Parts to find fauly apps!
- Check once in a while if there are any dodgy apps keeping your phone awake, causing your idle power consumption to be pretty bad!
Discharge your phone in a pattern of 100% to 20% and recharge
- Keeping cycles like this where possible, especially just after resetting battery statistics or installing a new rom, will eventually mean your battery will stay better for a longer period and you will notice your battery-life should be ok.
Make sure the minimum number of apps are running as services
- Go to Applications, Active services and find which unused apps you can disable.
Turn off Wireless Network Location if you are not using it
- Go to Location and Security, and disable use wireless networks.
Make sure not to use a task killer, especially not with automatic killing
- Sometime a taskkiller can be good to stop a app that hangs or causes issues, but make sure to not make it a default practice. To optimize battery usage, please tune the min/max of free memory managed by Android subsystem itself. Download Minfreemanager from the market, and set empty app to 96mb and content provider to 64mb and make it stick after reboots. This should make sure your phone will not slow down after a while of usage and enough inactive/idle apps are closed in the background.
Set Facebook / Twitter sync to once every 2 hours or more
- Make sure you don't let your phone sync that often, better to update it manually when you want to see it instead of syncing that often. Especially with Twitter having push now your direct messages will still turn up instantly even with slow synctimes for non-direct messages.
Watch out with Picasa sync
- Great feature, but dangerous since if it decides to start syncing when you are not on WiFi with bad reception, since it will mean it will sync potentially for a long time, destroying battery-life unexpectedly. There should be an option to sync this only on 80%+ battery only on WiFi but there isn't any, unfortunately.
Disable Google Latitude in Maps if not used
- If you need a longer battery-life, make sure you tell Latitude in Google Maps to not update your location (also see the point of network location), and make sure you sign out of it as well (so it doesn't update in the background if you are not using it).
I will update this and looking for good suggestions, please let me know especially about network-type GSM auto (PRL) and if it makes the same huge difference on your side. Also, another note, I am using 0405 baseband since I find best battery-life bundled with the RIL from a Vodafone Spain 0405 RIL as shared here.
Good luck improving your battery-life!

Im trying it out, but just an observation, the setting goes back to WCDMA prefered when you reboot the phone. Any way to make it stick?

Just shut down the phone and restarted and setting has not returned to WCDMA preferred on mcr fr19 but stayed on GSM auto (prl).

I think that if you tick 2G only on and off again it will go back to WCDMA Preferred.

mine definitely does not stick and i havent toggled 2G or anything else...

Thanks for the advice, seems to have done the trick for me. There seems to be very little speed difference with GSM auto set, I'm sure the improvement in battery life will compensate for the decrease in speed

Just restarted the phone and the network was reset to wcdma preferred
However good tutorial

It's not saving. Goes back to old values.

Click on menu button and choose save and apply at reboot.
Not sure why the wcdma settings keep being restored for others. Are you guys using cm7 or stock/mcr?

For the ones having the problem that wcdma settings keep being restored, just enble 2g radio only first, from the wireless menu. Later repeat the indicated steps and reboot. Did the trick for me.

I agree with you in all points - except for this one! I could not believe it myself but it has turned out that I get the best battery life on my O2x using this combination:
- MoDaCo FR19
- Baseband 0530
- RIL 0622
Baseband 0622, which is actually recommended for FR19, was horrible for me regarding battery life! I was surprised to see this non-matching combination provide a far better experience! Also, no problems with connectivity or call quality whatsoever. I'm on Vodafone Germany, for what it's worth.

Interesting. Do you see any dialer wake in spare parts at all? I notice I recently got android system playing up quite a lot, no idea what is causing it :-(
Sent from my LG-P990 using XDA App

Yes, I see the Dialer show up in Partial Wake Usage. It's on first or second place, but the blue bar is not very long though, maybe 3-4 mm.
Dialer usage seems to increase after 3-4 days of uptime, strangely...

This was missed in the original post so let me add my two cents worth.
To save even more battery, I would as well, advise paying some attention to screen brightness and wallpaper/theme selection.
In my experience, you can save 20 to 30 mAh by turning off Auto Brightness and setting it to something lower. The auto brightness control in O2X is overly bright and dismal in its operation. It barely changes in response to varying light conditions.
For this, you need an automation app called Tasker, or something similar. I use Tasker to control all manner of things including all the network situations mentioned in the first post of this thread. For saving battery in relation to screen brightness, I use Tasker to set screen brightness to 70 during the day, and to turn it down to 50 during the night. You can adjust these to your own preferences. But, as mentioned above, running these values saves me about 20 to 30 mAh of power when the screen is on.
In general, selecting darker wallpapers and themes will also help you save some power. Many messaging and email apps, for example, will give you a choice of a dark or light theme. If they do, I always choose a dark theme to ensure minimal power consumption.
My two cents worth

Not a bad point, thanks. I am using a low manual brightness, is there maybe a brightness bar widget so you can tune it manuallly directly from a homescreen? That would be great.
And of course you must be crazy to use live wallpapers. Why would you want to make your battery last shorter and your homescreen slower and more annoying to look at?

Yeah, good additional point that I missed about the live-wallpapers
I use a small app called Quick Settings which installs in the pull-down notification screen to quickly adjust screen brightness if I need to override the auto settings I set in Tasker.
PS. You might want to update your first post with the info about controlling screen brightness since many users are ignorant of the default auto-brightness setting, AND your post is very useful and I see it being referred to as a solution quite often. I was made aware of this thread from way over at Modaco. Good work!
Hope the moderators will stick this thread to the top of the forum.

I thought dark wallpapers are more needed for devices with amoled displays. 2x has got a lcd am i right?

I guess I was hoping for a little more detail than that.
More powerful how, precisely? Does it boost the signal strength by pushing more power into the phone's signal? Enable different networking standards? Up-clock the circuitry?
One thing it certainly seems to do is absolutely pulverise the battery; I'd like to know what the trade-off is.

Best WiFi performance, silly
Seriously, I switched it on and off. No difference. ~47Mb/s down, ~15Mb/s up.
I've never got more than 15Mb/s up no matter what settings I use.

in my opinion it is just for signal strength...

Well, there is a similar feature for the Note II and what it does is allow you to hang onto poor wifi connections which will drain more battery so the option is disabled by default.. Maybe that's what it is on the HTC One too??

Anybody using this?
I'm having trouble with my push notifications over wifi (being delayed if the screen is off) and I think it has helped me receive them.
Does it drain much more battery?

[Q] How to set 3G connection to be always on

Would like to know how can I set my LG Optimus 4X HD (with app or settings) so it is always on line while on 3G or WiFi even if I lock the phone?
I have unlimited 3G plan so I don't care about data traffic and no mater what I do battery last 1 day, so I don't care about power saving.

Settings - Screen - Set screen timeout to 30 minutes or something, It's not smart to keep 3G - Wifi online, as it will wake your phone from deep sleep and It won't even last 1 day like that.
You gotta find a kernel with no deep sleep support.Also why do you want your 3G to be on while screen is off? Thats nonsene.Most of the apps that use your 3G would keep your phone from locking the screen, so your phone wouldn't enter deepsleep and they could resume downloading.If you wanna save battery by locking the screen, just turn the brightness down.
Try to delete bloatwares, that increased my battery life from 1 day to 2 days, with moderate usage.Try using some different kernels also.
Whats your purpose locking the screen while 3G is on? WiFi hotspot or something?

by default, your 3g should stay on when you turn the screen off/lock it, if they're enabled. you only need to do some things if you DONT want it on when your screen is off.

Background services? Push notifications? It makes much sense (are you sure what you're talking about?). But on the other hand: if there are apps requiring network for such purposes, they usually take care themselves for this requesting corresponding wakelocks from time to time (background services). Just push notifications work differently, but here the core system should take care.

That's plain nonsense. Though they could do so (e.g. requesting a full wakelock), they usually don't. Want an example? Ever heard the chime for a new mail having arrived, as you set your mail client to poll at certain intervals? I've never seen the screen turning on for new mail polls. But admitted, I'm not constantly staring at the screen

You wouldn't receive emails 24/7, turning 3G on once an hour or two is enough to check notifications.You wouldn't notice any notifications until you turn on the screen anyway.

Nope, I just didn't get what he means.He should try to be more specific.His question is short and simple, no one can do anything without knowing what he is trying to do.Theres multiple solutions to a problem mostly and he is just focused on one of them.Keeping screen on 24/7 is not a solution.He should try to use third party apps, some should have options to notify him in some way, It's just nonsense to keep screen on 24/7.

(emphasis mine). He didn't ask for the screen being on, but for the connection. While for 3G, to my knowledge that's the case anyway (as @Flying_Bear already pointed out), this is different for WiFi depending on the settings (WiFi standby policy).
@denis1304: In WiFi settings, you can configure this in the advanced menu.

Hello again
Let me explain on example what's that I want from my phone if it's possible.
I use app MightyText or MySMS and while on WiFi it works instantly but if on 3G and phone screen is off for some time, sending SMS start to lag and you need to wait for 10 or 15 minutes for SMS to go through.
Or when I want to install app from my PC over play website its takes also 10 to 15 minutes to start installing app.
While on wifi it takes much less time or start instantly.
Hopefully I explained what I want so you can help me or I expect too much.
Thank you, Denis

While this won't help much: In both cases you mentioned, you are actively performing a task. So you could simply switch on the screen to speed up the action. I've no idea how to do that in a different way automatically, at the moment at least.

Wrong again. I hear a chime (new mail notification sound), and then I maybe turn on the screen to look what it was.
Again, that was not what he asked:

Nice quotes...
In both cases, turning on the screen and 3G once an hour is enough.
Turning the brightness down could save him from locking the screen, that was my point.

It is what he exactly asked.He wants his phone to keep 3G - Wifi online while screen is locked.So keeping the screen on wouldn't be a solution, and a third party app could help.
Well, good thing you actually tried to help OP with a few words.You could do that before instead of arguing with me.XDA is no such place, if your commenting on some troubleshooting topic, you should focus on OP.Correct anything I write wrong, BUT focus on OP's question first, thats your priority.
@denis1304
You should try JuiceDefender, I know it's actually a battery saver, but I remember it had some options to sync stuff even while screen is locked.You can set how often it syncs, or turns on the Wifi or 3G to perform such tasks.
