Regarding Batteri Issues "Temp fix maybe" - Galaxy S II General

Hey,
Iam getting my phone tomorrow, but i have been doing some reading in the different topics.
I found this link in one of the topics postet by "xdadroid88"(thanks to him
http://code.google.com/p/android/issues/detail?id=15057
i have read through it and this is the tips i found.
1. Set the wifi policy on "always on"
2.Location & Security -> Use wireless networks / Use GPS satellites. I've disable both options
3. switch off Latitude
Seems like this is a issue in Gingerbread 2.3.3 and is resolved in 2.3.4
Try this and post the results

So disable wifi/gps and battery is better? That's news!

Dont need to be rude, just trying to help, it can be a different problem on the sgs 2, just telling people what they can try and maybe maybe it works for some

LOL.......

That's not even what he said, those settings are for letting your phone track your location. :-/
I'll give this a go OP and post tomorrow. Thanks.

the OP actually meant to say "wifi sleep policy". and yes the issue was with wifi. ironically setting wifi sleep to NEVER is better for battery life than letting it go to sleep, because when it switches back to 3g it uses more power. leaving on wifi always uses less power than leaving on 3G because of latency and other factors. counter intuitive but true.

Possible cause and solution to X10 Battery? -"No Sleep Bug"

Hey guys,
Just updated to the x10 after my samsung galaxy died on me, so far i am rather happy - except for the lack of root, but that will come.
I have noticed many complaints on the forum about battery life, and have experienced the same thing myself. From my experience, i think this looks like the same issue that was faced on a leak of 1.6 for the galaxy - it was referred to as the "No Sleep Bug".
TBH, the name says it all - for some reason, in many builds of android 1.6, phones were not sleeping correctly. There are many theories as to why, from cpu not being allowed to sleep, to permanent communication with google servers.
Despite all these different theories, one thing seemed to fix the problem - turning off all location services. Some people argue that a different carrier build, turning off just 'share with google' under location, turning off just AGPS etc. would fix it, but from my experience, the only real way to fix the issue was to turn off all GPS usage unless you need it. The once you have used it, reboot your phone.
This fix obviously sucks, and a new fix has recently been released by a veritable android-demigod around the Galaxy.
HERE IS A THREAD ABOUT NO SLEEP ON i7500 GALAXY;
(ok, some stupid rule says i can't post links - can a mod help me out?)
HERE IS THE FIX FOR THAT PARTICULAR BUG;
(ok, some stupid rule says i can't post links - can a mod help me out?)
LINKS ARE IN POST #5 - THANKS TO ONDOTEAM (would still be nice to get them in this original post though)
Now, from my experience, no sleep behave exactly the same way on the x10 as it does on the Galaxy;
1) I turn of all location services, and my battery life at least doubles.
2) After said turning off of services, 'spare parts' no longer says 100% running time under battery usage - in fact it can be as low as 10%.
These two factors are identical to my experience with Galaxy. SO; is there any way drakaz's fix can be applied to our X10's? It seems to me that the files he mods are standard Android system files, not sony/samsung specific.
Now i am no developer, so i dont know it this is possible - the first question that comes to mind for me is "do we need root access, or can this be done through developer tools using the android SDK?"
Can anyone help shed anymore light on this?
Seems to work for me. I disabled all location services. Spare Parts went down from 100% to 7.6%.
I'll just have to enable GPS when I need to use it..
Awesome! Glad to hear it has helped.
Let's keep testing this guys - if it does show up to be a big cause, then perhaps the devs around this place can help is figure out a patch for Drakas' mod to make it work with our x10's!

No sleep is easy to fix, took me a while to figure it...
Turn your screen brightness from manual to auto, spare parts will now start showing proper running stats, no more 100% running.
The screen is a little dark in auto but it will cure the 100% running.
GPS and location services etc make no difference to my X10i, I am running the 1.6 version unbranded UK handset, the only thing to stop mine running 100% is to put the screen on Auto.

My phone came out of the box with auto-brightness and i never changed that option, yet i still had no sleep.
Drakaz has done some fairly deep digging and is next to certain that it is an artefact of the geolocation bug discussed in the thread in which the problem was fixed.

Spare Parts is a standalone Program ...

Spare parts is indeed available from the market - it is a much more powerful tool for indicating battery usage than the regular android methods. The galaxy stared on 1.5 which had NO indicator of battery usage statistics at all, so we all learned about spare parts very fast.
Perhaps that is why no x10 users have realised about the potential no sleep bug; because so far only the android usage indicators have been used?...
Anyway, hopefully this can help us all understand the way our phones are working better together

14% it's mine value for running time, not 100%. By the way thats 30 minutes of 210 in total :S
I'm also experiencing "No sleep bug" after i used GPS. I use Battery Graph to plot my power consumption and after I use GPS, I can clearly see that power consumption is high even if i turn the phone in plane mode.
In addition SE widget, used to turn on/off GPS, seems to not work very well for me. So, to fix the bug, i manually disable GPS in parameter menu and restart my phone. After that power consumption is hardly null (20% in 8h with MP3 on almost all the time).

Do you have 3G always on?
My phone has no trouble sleeping.
Gps hasn't really been an issue but I keep it off when not needed.
Here's my solid settings:
1) No auto sync
2) No moxier
3) Gps off
4) Restart after using wireless
As long as it's like this my phone lasts 2 days easily

I have been playing with mine for a month to work out what caused mine to not go into sleep, I keep GPS wifi etc on 24/7 but in spare parts I was running 100%, after numerous reinstalls and removing everything i chanced on turning on auto screen brightness, now when i unplug my x10 the running sits at the correct level.
No Geolocation bug here
I have this problem with 100% on and off. Sometimes when I check its under control (~10%), other times its at 100%. I have GPS off, no WiFi, auto brightness... don't know why it sometimes just gets stuck at 100% :/

Full battery drain in just 6hrs!

Battery drain in just 6hrs, 2.2.1 JPY XEU. (while idle overnight), phone was turned off in the morning from 100% before going to bed. (completly drained)

Sorry to jump in but can you tell me where you found this, I have gone into settings wifi but cannat see it anywhere
If you have disabled GPS and Bluetooth read the following, if not do so and come back^^
1. Go into battery stats and look out for anomalies
2. let your phone run out of power and shut down by itself, if the drain does not change significantly after that.
3. think about your installed apps. chat apps like skype and facebook are evil battery eating bastards.
4. check out whether your modem fits your region
5. Reflash the kernel

I had sort of the same problem as well. I downloaded Android System Info and went in to tasks and killed com.seven.Z7.service, and that made it stop use my data transfer 100% of the time. Worth a shot? I think it's the SGS email client, that has been reported before as well. Weird cause I've got push email, but still...
Its definatly a wifi issue, i thought a full wipe AND and fresh rom flash would clear it - but no luck

Easy Fix... (For the SGS anyway)
Go to... Menu>Wireless and network>Wi-Fi settings.
Uncheck "Network Notification"
Then tap the menu button (to the left of the home button) and tap "advanced"
Select "Wi Fi sleep policy" and set it to "When screen turns off"
Your battery life will improve drastically. Just drain the battery fully, and give it a full charge.
Let me know if this helps you.
Rom Kitchin build your own rom choose modem and csc .

You get no scanning for open networks so maybe you stop to scan networks while associated.
I think this is a problem with the modem.bin try to flash other one maybe JPY, JPU or JPM
Can you please check in wi-settings and see if it keeps scanning every 5 seconds when already connected to wifi.
... It may be normal behaviour, but.i doubt it.

keeping the radio you dont have off

I found a program called Nobars in the market. What it does is monitor cell reception and turn the radio off when you have no signal. There is an option to keep WiFi active when it puts it into airplane mode.
I have confirmed that it works as it should by taking it out of airplane mode several times. Since installing it cell usage of the battery has not budged.
I know this can be done manually but this is an automatic option that constantly monitors.
Nice find

Does this need root?
Cause it doesnt seem to work on mine (note rooted yet)
I dont see any notification as the settings suggest..
Its not working for me neither.
Mine is unrooted too.
Do we need root?
mine is rooted and it doesnt work : still have the "veille gsm" process sucking battery (A500 french)
I am rooted, it doesn't work for me either.
Does Airplane Mode Work?
Has anyone seen any positive effect of keeping the tablet in airplane mode and just turning WiFi on/off as you need it?
This app does not need root. While it was working great for me initially it now seems to have stopped working. I am going to play with it a little today.
And I definitely see a difference running in airplane mode.
There is another app I run on my droid x that shuts down everything at night. Going to see if that works on Honeycomb.
for anyone that it is not working for, you can turn on airplane mode manually and then re-enable wifi

You can do this, but have not seen any adjustments to the battery use at all. It still keeps draining for the cell standby.

Airplane mode does not fix the Cell Standby drain.
I have seen this topic discussed in the Androidtablets forum under the Acer specific thread. (I still can't post links but it's exhaustively been discussed in that thread).
Unfortunately, the a500 was designed exactly the same as the a501 (which will be the 3G enabled Acer tablet eventually).
The bottom line is, this probably won't ever be fixed. Renaming phone.apk and telephonyProvider.apk does fix the issue - but it also bricks your tablet.
For my Droid X, I use a widget called "Dazzle!" which gives me control over the Cell Radio - even on my Droid, I can disable Cell and not have a Cell Standby drain. Unfortunately, this widget does not appear in the market for the Acer...
I think we've gotta wait for a crafty developer for a workaround, or wait for some custom ROM's... Acer doesn't seem to have any plans for a software update for this.

All we need is a kernel that disables the ril. DJ_Steve did it for the Streak 7.
I have a help-ticket out at Acer about this issues, which has already surpassed Level 2 Tech support. It's been a while since my last response (which told me to send the unit in for faulty parts, haha). We'll see what Level 3 has to say. So far they've only sent form-letters back.
I have a feeling our developer community will have this issue solved well before acer even acknowledges it.

Which leaves us users who don't want to go the mod/root route in deep doo doo.
I completely agree.
I finally decided not to root my Droid X for the gingerbread update. But the tablet, I have to admit, I might have to actually Root to fix the issues.
I hope Acer creates a situation where Rooting isn't necessary. But, it looks doubtful. I'd rather root and gain 4+ hours of battery, than not root and gain nothing.

How is your battery life before and after? And, renaming them does nothing unless you reset the Iconia.
What I don't understand is just what kind of reset does this. There's a lot of chatter here but to me a hard reset always meant a complete wipe of the device back to factory default state. Apparently even a "soft reset", i.e., just rebooting will also bork the Iconia so just be careful.
Am I on to something here?
Hi guys, I am a noob here so please dun flame me
I actually installed minimalist text onto my A500. I tried to customize my widget,
and when I went into the part where I can customize the activity of clicking my widget, I discovered that the list consist of mobile network settings (It actually consist of the full list of mobile networking settings)
Out of curiosity, I selected the mobile data network setting as my widgets default action. When I went into the setting, the "Data Enabled: Enable data access over Mobile Network" is actually being checked. I had unchecked it, and now my "cell standby" in my battery use has stopped.
Maybe I got it wrong or its just coincidence, but I thought maybe someone else can try it and see whether is it really workable?
I am keeping a look out on the battery statistics; hopefully it really works.

Wow! I just went into my Beautiful Weather settings and under the "Advanced Panel" you can specify an action for clicking on the time (or weather). When this is done, it provides a large list of action - this list, to the best of my knowledge, doesn't show up anywhere.
Anyway, Mobile Data was checked (yes or on) so I cleared the list (resulting in mobile data being UNCHECKED) and rebooted. Mobile data remained unchecked so I'll watch for a while and report results later.

Yeah the list didnt show up anywhere unless we went to customise widget setups like what we did. Lets see how things goes!
And it seems as though the mobile network settings etc is hidden due to the fact that our A500 is wifi only?

Save battery by keeping WI-FI alive...

This tip is one that seems counter-intuitive, but you can save a lot of wear and tear on your Android phone's battery if you tell it to keep the Wifi radio turned on and connected while the phone is sleeping. Your phone needs a lot of juice to keep pinging those cell towers, and even more to transmit data to and from them. Wifi radios use much less power because of their design, and they don't have to keep searching for a better access point. It's the way cellular data communication was designed, and it's a necessary evil.
But what if you're spending all day (or all evening) in one place, connected to Wifi? If you tell your phone to shut off Wifi when idle, it bounces back to cellular data (be it 2G, 3G, or 4G) and starts sucking down the electrons again when the screen shuts off. That's no good, and easy to fix:
Open the advanced Wifi settings by pressing the menu button, then Settings, Wireless & networks, Wi-Fi settings, and tapping the menu button again. You'll have a choice to either Scan, or go Advanced -- go Advanced.
Tap the Wi-Fi sleep policy entry, and you'll get a pop up dialog with the 3 choices. Choose Never.
Now even when your phone goes into standby mode, you'll stay connected to Wifi and be able to get mail and messages without turning the cell radio back on and trouncing your battery life. And for the times when you're not in an area with a Wifi connection, just shut Wifi off, either through the menu or with a handy toggle widget. Your battery will thank you for it.

i thought as much myself.
as far as i understand, this is useful if you also have and use internet from the carrier, so if you keep wifi on and use it rather than 3g, which uses more power, you will have lower battery consumption. but if you are not synchronizing data during night, by keeping all connections off, you will not need to keep wifi on, am i right?

besides: the reason why OP got better battery with wifi turned on (when screen off) is that this avoids the android OS bug (suspend & event/0)...

This is the worst thing you can do in terms of battery life on SGS2, since this kicks the famous Android OS bug into high gear, especially on D-Link class routers. With wifi sleep set to never, my SGS2 loses around 10% an hour just sitting completely idle.

[Q] Wifi disconnect in deep sleep since cm10.1

So I have seen this come up in many many different threads and phones, where users complain about wifi cut off or radio toggle when in deep sleep. it seem to only happen to cm based roms.
I've read the suggestions like making sure your wifi is always on or change the region code to Canada but those never took care of the issue.
In a way i kinda accepted the issue as a side affect of using CM roms.
are there roms that don't have this issue? are there any fixes for this?

May be obvious but have you checked to make sure that Keep WiFi enabled during sleep is set to Always On?

May be obvious but did you even bother reading my post? it STATES, it is set to always on.
bump, anyone?
What radio are you on? Is your WiFi actually not connected when you wake your phone or do you just get delayed notifications on WiFi with the screen off? As a test, try setting a "static" IP on the router for the phone.
Sent from my phone. Please forgive typos and brevity.
I've had this issue on a few different roms (CM included). Whenever I was listening to radio over wifi, the stream would cut out whenever the phone went into deep sleep (even with the "Keep Wi-Fi on during sleep" setting enabled). Pretty damn annoying!
In my case, I've recently solved the issue by changing the "Wi-Fi frequency band" to "5 GHZ only" and unchecking the "Wi-Fi optmization" option.
This was on the PA 3.99 RC2 rom btw.

has that affected your speed on wifi? illl try it now.
disabling wifi optimization is suicide.
ok guy, http://forum.xda-developers.com/showthread.php?t=2300873 and http://forum.xda-developers.com/showthread.php?t=2072930
arp offloading works with .84. However, CM has it disabled nonetheless. Enable it and if necessary, add (increase) the inactivity timeout to 200ms and things should be a-ok.

No. Seems to be as fast as it was before.

Not really. I'll take a very slightly reduced battery life over constant disconnections any time.
