I'm on zeus 6.22o, my battery consuption is high, tried 6.22n but is the same and o version works better for me. I have always 3g on; in stock froyo and cm7 nightlies with 3g on and same apps and config I had better batttery life and the phone normaly went to deep sleep when I turn screen off and had considerably less wakelocks, battery graph was quite horizontal.
I have installed betterbatterystats and the problem is:
-Partial wakelocks: Datatracker-FD
-Kernel wakelock: PowerManagerService
-Alarms: com.google.android.gsf (gtalk_reconnect; gtalk_heartbeat)
They produce the most wakelocks.
I have freeze gtalk app with titanium because don't use it but it isn't the problem and waakelocks are the same.
Does anyone know how to fix it?
Thanks and sorry if my english is not good enough.
-Kernel wakelock: PowerManagerService
-Alarms: com.google.android.gsf (gtalk_reconnect; gtalk_heartbeat)
gsf = google services framework
are not causing preoccupations, these are system relevant things. A wakeup isn´t at all a bad thing. Bad is when a process begins to work an to force the cpu for a prolonged time.
-Partial wakelocks: Datatracker-FD
Try to turn fastdormancy off maybe your provider don´t support this.
All this things don’t explain a higher battery consumption.
Regards!
Thanks. I tried disable fast dormancy but it doesn't help and causes problems with data network. Awake time is about twice the screen on time and these are the only with high values in betterbatterystats. Other apps are the same I was using in stock froyo and cm7 (in both I had better battery life): go launcher, whatsapp, hotmail (never had battery problems with it), tapatalk, sygic,a few games, mjoy.

Now I'm experimenting a huge battery drain due change WiFi policy to "never" turn off. It leads to a consumption of 4-5% per hour. Normally, with turning Wi-Fi off, there is a consumption with 3G on, of 3-5% in 8 hours.
BetterBatteryStats since unplugged:
Kernel Wakelocks: "wlan_rx_wake" 30%
Cpu-Spy reports for the same time CPU-activity from 300MHz.
Tried change Wi-Fi voltage via Zeustweaker, but doesn't seem to work. Changing 20 - 14 -10 -8 - 2, no matter in range of Wi-Fi nor in indication of the Wi-Fi symbol in the notification bar (of course switched Wi-Fi off/on after each change).
Someone an idea?
It's like some app maintains your wifi connection active long time.
In 3g my conumption is about 12% in 8 hours without use.

I think that if you select "never" at the Wifi sleep policy then it actually never disconnects from Wifi, which in turn means that the phone can't enter deep sleep. At least for me it always worked that way, even on another android phone.
Thank you verszipo for your hint. The rest of the time (70%) the cpu is in deep sleep. I will try this in v10, because I think this old one is a lot better programmed than the v20.
Although wifi was always connected it doesn't mean that is always active, like with 3g when is connected but arrows aren't blue. I think it can be an app that keep wifi active or an error in wifi on v20.
Enviado desde mi LG-P970 usando Tapatalk 2
I agree with you, jes0411.
Now I can confirm, that the v10 based Nova8 have the same behaviour like the v20 based Zeus 6.22. So this not seem to be a Zeus specific issue. Maybe cause by LG´s provided code or an generally android issue?
I installed a fresh Zeus 6.23 without any app beside cpustats, betterbatterystats and of course the apps inside de Rom. Here the results with Wifi policy “never”:
CPU SPY:
Total State time (approx. values): 13h
From This: 7h 15 min deep sleep, 3h 20 min by 300MHz, 2h 8min by 600MHz, 10 min 800MHz
BETTER BATTERY STATS since unplugged (approx. values):
Kernel Wakelock:
wlan_rx_wake 4h 20min, wlan_wake 1h, PowerManagerService 8min
Other:
Wifi On, Wifi Running, No Data Connection, No or Unknown Signal: all this 13h 9min 21s
Deep Sleep 7h 15min, Awake 5h,54min, Srceen On 15min
Partial Wakelocks (all insignificant):
WifiStateTracker 3min 55s, *Wifi* 2min 51s, GTALK_ASYNC_CONN 41s, AlarmManager 37s
Alarm (also all insignificant):
com.google.android.gsf 46Wakeups, android 10wakeups, com. android.vending 1wakeup.
BATTERY CONSUMTION: 47% in 13h of inactivity: approx. 3,6% per h
RESUMING:
Wi-Fi policy “never” causes an inexplicable CPU-activity of around of 40% of the time where the phone is unused. No application seem to cause this behaviour. The CPU not only is waked up, it has to work, so that around 40% of the wakeup time the CPU operates with 600MHz.
WiFi is NOT used for Data-transfer!
CONCLUSION AND FURTHER STEPS:
This is an not acceptable behaviour!
I will freeze vending, gtalk and gmail with titanium and observe it again. I also will change the Governor to OndemandX and use a Firewall.
Stay tuned!
I have a feeling for some reason that Froyo was better from Gingerbread in terms of battery consumption,
Is it true? What are the improvements on Gingerbread?
To be honest, in battery consumption I don't see any difference between the v10 (Froyo) and v20 (GB). The only what I see as advantage in v20 is the more fluid reacting user interface.
Negative points in v20:
- Removed the led attenuation of the keys
- Removed the possibility of use key leds for call, charging, sms... notification
- No stable reconnect to WiFi with hidden SSID
- Buggy music player
Also again thank you LG (this is sarcasm).
Since publication, from now around 4 months, they haven't fix this. I fear that ICS will be the same trash.
RESULTS of testing:
Results of freezing apps vending (google play), gtalk and gmail:
none, wlan_rx_wake still in huge consumption
Result of Use Firewall: no change, wlan_rx_wake still in huge consumption
Result changing governor from Smartass to OndemandX: no change, wlan_rx....
Result of switching of my WiFi-router: Success, wlan_rx_wake doesn’t appear, battery drain in normal way (around 0,3% per h).
CONCLUSION:
This huge battery drain caused by Wi-Fi is a result of the combination of an P970 and a specific Wi-Fi routers. A Google search results that not only our device is affected, also found Samsung Galaxy S2 and Note.
SOLUTION:
Buy another router or an other not Android-based phone.

Hey Pacos1 (fellow Spanish here)
I dont own an Lg but I do own a Galaxy s2 and now Im having the same problem as you guys but in a veeeeeery reduced manner, those wakelogs due to the wlan are call for around 3-4 % of my battery, still good battery life altogether. The reason Im posting here is to let yo guys know that i didnt have this problem before, I didnt even see the wlan wakelogs in the list of betterbatterystats since they were so little, and this is due to a change in the kernel, which is exactly what rules the wifi behaviour, I suggest you change it and try a different one if you have the chance and youll probably experience a change.
Cheers ( y saludos)
Thanks paieneso for the hint and this is truly the solution. I tried the CM7 build78 from temasek, which comes with another kernel than the stock one (and stock derivates like Zeus) and the wlan_rx_wake issue disappeared.
(ironic mode on) So, thank you LG, once again! (ironic mode off)
But now is a new stock rom out, the Spanish v20Q, will test it if this one makes a better job.
Saludos!
PS: Sorry, I forgot this thread and also to post the “solution” of wlan_rx... .
The new stock v20Q have still the wlan_rx_wake bug!

Since everybody has some problems with battery drainage i thought it would be usefull if everybody posts his or her battery stats after some time so we can compare them so we can find and solve "problems".
Add in your reply:
-Which rom are you using ?
-How is your battery doing over the night ?
-Is the battery inaccurate like it doesn't go higher then 98%, drops from 100 to 50 after some time or after reboot,... ?

Allright so we can already see that the stock rom's don't have much of draining or am i wrong ?
because my stock also had less then 5% loss at the night
but your 3G is ALWAYS ON !!!!! :s
you mean that you can always use 3G without doing anything else to your settings after disabling wifi ? because the 3G icon is always noticeable on the status bar even when it's disabled

Yes. When at home both 3G and wifi are enabled.
GSM coverage is not great in some parts of the house where my router wifi is strong; while some rooms far from the wifi router gets decent GSM coverage. So, I just let the phone choose whichever way it wants to connect when at home.
When I leave home, I manually disable wifi with a widget to save wifi scanning for router whenever the phone comes out of sleep. 3G works everywhere else, so I just leave it on 24/7. 3G power usage is negligible when there is no data traffic even when it is enabled, it's basically GSM on standby power.

I think EDGE is like a fast GPRS connection, right? I had used GPRS (aka 2G) quite some time ago, and IIRC, GPRS is billed by data connection duration rather than by data traffic. If it's also the case for EDGE, you MUST NOT leave is enabled 24/7, or else you will get a gigantic phone bill at the end of the month!
But regarding EDGE's power usage, I am afraid I am not entirely sure if it behaves like a 3G connection. Best is you test it out while monitoring battery drain, or google around for the info.
-Which rom are you using ?

Around 5% loss, during around 8 hours of stand-by. But I usually charge it over night.

I'm gonna try the old style Nexus One's method of battery calibration. Hopefully it works, though I am not confident.
1. Plug-in charger standby, do not turn on charger yet.
2. Drain battery till it auto shutdown.
3. When it auto shutdown, immediately turn on charger.
4. Let the phone charge for 4-5 hrs.
5. After 4-5 hrs, power up phone.
The above was the Battery Calibration for Nexus One before N1 has its own Battery Drivers build-into kernel and a proper Battery Calibration Application (found in Market).
As I said, I'm not confident but will try this method. Will report here if success or failure

Probably a good idea to have a small fan blowing to avoid the phone shutting down from the heat from a long recharge. Might also have to go through a few cycles to reach the battery's full potential, probably don't need the empty-to-full cycle. Please let us know what you find out.

I've accumulated tiny experience over at Nexus One Battery Calibration and I know a small thing or two about how "some" batteries work.
The thing about Nexus One battery is it has in-build EEPROM so its the almost perfect battery to perform calibration. As for O2X, its still infant stage so no one look into it yet. But the theory "should" be similiar.
I'm doubtful but hopeful
Edit 1 - heavy usage with screen on for 4.5 hrs. 12 hrs use. Manage to drain battery till 0% and it auto shutdown as I expected. Now performing off charging for at least 4 hrs. I was surprised to see before it auto shutdown where at 0% the voltage was 3362mV. Pretty impressive I would say. Now I'm optimistic ...... will report soon.
Edit - failed while auto shutdown I plugin assuming it was charging. 4.5 hrs later I power up and it is at 1%. Fail!
I plugin and start charging. Monitored the charging process and found for the first time the phone was cool while charging even cool till 100%.
I'm now using this new charge and seems good. Its cool, no longer hot.
Now i have got CM7
And must say that battery is holding out much better at sleep
4 hours and not even 1% down
So i would advise to switch to CM if you are trying some new roms !!
Have you guys tried the app BatteryCalibration from market?
I had the same prob as many of you, and this solved it for me.

Though I know gb roms don't have such a great battery life it seems as if my battery is draining faster than it should despite changing to different roms, calibration, changing batterries and deleting apps or widgets . (Currently gamrez rom which has been said to have quite a good battery ) .my battery drain is about 10 percent an hour with a mild to idle use. it's been like that for my old battery and even for a new 1800mah. I suspect there might be a program respobsible for this.
Since these programs dont appear under battery usage, yet are considered services I think the culprit is one of them.it might be that one of them is preventing the phone from going to deep sleep so the battery drains when idle.
My running programs are:
Go launcher
Go keyboard
RocketDial pro
3G watchdog (sync every 15 minutes)
Call meter 3g
Adaway
Auto rotate
Sanity (only for auto handsfree)
Bussiness calander free
(before anyone blames it on these three, it happenend even when they've been removed )
Viber
Whatsapp
skype (service autorun disabled and usually not logged in)
No stock email
Also as far as widgets are concerned I have a widget for callmeter usage. 3g watchdog and bussiness calendar agenda. and sync for google stuff , whatsapo and viber.
I know it's a lot of stuff, but I've been tweaking and picking these programs since I really need their functionality.
Under battery usage most of it goes to display (about 50%)
People report better battery under heavier usage so something most be wrong.
Didn't have time or nerve to switch to ics but I'm affraid it a program so it won't make a difference

There are many system monitor apps available on market.. install one of them and try to find out what is draining your battery.. sometimes it turns out to be the least expected app/ service..
Hi,
install "Quick system info pro". In the info tab, tap "battery", then "battery history" and you'll have all the info you need.

Thnx, I've install badass battery monitor in hope to put an end to this mystery. Still, I was hopnig someone could rake a look at the list i published and maybe shed some light if anything pops out.

Go keyboard
I've just installed go keyboard and typed 'top -m 5' to see top cpu users. go keyboard was in first place. After one hour phone idle, battery has been drained by 5% Maybe it's just my cfg problem. But.. that's just an observation.
This is just an idea and I might be totally wrong.
But doesn't it take like 10min for a phone to go to deep sleep?
So if you got am app syncing every 15min you get out of every 15 min 5 min of deep sleep.
It's to say you would normally have 50 min of deep sleep in an hour whereas you would have like 15 min.
And you could check the percentage of how much battery an app uses through the battery info in the settings and to check if your phone goes into deep sleep you can instal the app CPU spy.

you can increase battery life in every kernel. Under clock your cpu or change the governor. There are few apps for this, best for me is set cpu

I'm using mackay kernel and my governor is ondemandX
But under clocking will make the phone too slow (which I cannot get used to)
but in some roms like v30B ICS and I remember cm7 and Zeus
the whole night(wifi off / mobile data off / GPS off / Bluetooth off) just connected to network and it may consumes only 2%-3%
So is there any thing to do with Macaky rom/kernel

Set wifi to off, when screen is off, also I really recommend Greenify, this saves a lot of juice, if you freeze the right apps
Sent from my LG-P760 using xda app-developers app
I also strongly recommend Greenify.
I have purchased the paid version and have most of the apps (including system ones) greenified. Battery life significantly improved and no problem with receiving messages etc.
I use "Better wifi on/off" as well, to automatically turn wifi off when my home network is not connected.
I would also advise switching automatic sync off. That's the culprit of battery drain for my OB.
Hope these helps.
Hi, all CM 10/CM10.1 roms seems to be more battery draining.
Hi!
I just noticed that my phone does not go to deep sleep if I have wlan on. Though I do not have any long wakelocks according to BetterBatteryStats, just some minutes total while the device have been awake for much more.
Stock .534 unrooted, newly repaired with _only_ BetterBatteryStats and CPU Spy installed. No accounts added etc.
Wlan/Advanced: "Always on"
Location-based wlan: "on"
Low battery mode: "on"
STAMIN mode: "off"
Location based services "on" / "off" tested.
When I have wlan on CPU Spy reports as Deep sleep unused, and instead most of the time is spent in 300 MHz.
Any of you that can reproduce?
Have the same problem. Is that normal that it doesnt goes to deep sleep ?

No, it's absolutely not normal. Something is keeping the device awake, probably a bug.
I left the device over night,
wlan kernel wakelock for 7h, but no long-standing partial wakelocks. I don't get it, how can something keep wifi awake without actually issuing a wakelock?
Bah I have suddenly been afflicted with this issue since yesterday. Noticed battery drain from 100% to 33% with minimal use between this morning and lunchtime while at work. Currently it is charging off my laptop but only holding its own, not increasing. Only had it a week, very little installed on it.
Battery life was fine for the first week of ownership, today it lost 75% with little or no use in 5 hours, then it did not charge when connected by USB to laptop it merely held the same charge, before quickly discharging again when disconnected.
No deep sleep all day

Hi, can you please verify that you indeed do not have any wakelocks caused by any other third-party programs you have installed? Just to knwo that we are in fact experiencing the same issue. You could also try to disable wlan (and mobile data (I haven't tested to turn that on, as I do not yet have a data plan).

Today's issue on my phone was driven by several hours of a "bam_dmux wakelock."
edit: and no partial wakelocks so no idea of the driver.

Ok. So it might be the same issue then, though I don't really know what the "bam_dmux" wakelock is.
FYI Mine is back to normal today. Lost 3% in 3 hours of light use. Only thing I have changed is I deleted a Wifi network from my preferred list that the phone was having trouble connecting to, may or may not be related.
I got 99 problems but my battery life ain't 1.
How to get the best battery life out of your Nexus 5
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
11. Greenify: Works with and without root. Use Greenify to hibernate apps when they should not be running in the background. This is best used for games that fetch information about deals or daily events (i.e. Battle Nations or Real Racing 3)
Feel free to add anything to my list.

4, 6, and 7.. it would all depend on your signal quality. i get MUCH better battery life on lte than on wifi. and i mean much! i get 5-6 hour screen on time without doing anything special. on wifi i get an hour to hour and a half less. so the wifi thing is just in your situation, and not for everyone.
9.. there are better kernels than franco kernel. and on top of that, kernels have so little influence on battery life. battery life is mostly about your personal use, your personal setup, your choice of apps used, and very much on the quality of your phone/data connection. everything else has very little influence, including kernels.
3. This I agree. I've had super strange battery drain if I don't restart the phone once in a few days. I refuse to believe its a bad app as there are no wakelocks, seems to be more of a phone idle battery drain or radio drain.
4. To be honest, it depends on the WiFi network. Some WiFi networks (typically at universities) have a strange and outright horrible battery drain the moment you connect to their network and leave the screen off.
6. Again to not repeat what I said earlier, I get better battery life if I connect to LTE instead of my school's WiFi. Download speeds over LTE are 2-5x greater than my school's WiFi, so race to idle may be happening here.
7. Most android phones today have minimal battery drain with WiFi left turned on. But it doesn't hurt turning WiFi off if there are many weak known WiFi networks around you.
8. Not sure how much you'll save, I don't even recall much of an increase of battery with this off. YMMV situation I suppose.
9. I've had better battery life with other kernels. Again it's a YMMV situation.
Not a bad guide really
Another tip is that if Google Play services keeps your phone awake for a long time, revert Google Search to an older version, reboot the phone. The wakelocks should be drastically reduced.

Using Nexus 5 with:
CyanogenMod Nightlies
ElementalX kernel
1d 2h 9ms on battery / 2h 17ms screen-on time / with 38% remaining!
Good information! ?
Only thing I'd say is to just remove the part about kernel completely. As said above, kernel makes little difference. I get 24 plus hours and 6 hours screen time on any ROM or kernel. It's all setup and usage.
Nothing new here. Good for noobs, but most will have done this already
I have found that turning location off completely has helped my battery life tremendously. While I was barely able to make it through the day before, now I can easily pass by with 40% or something and light usage. I've tried other things but nothing has improved my battery life as much as turning location off.

Yup! That's what toggles are for. Need it? 2 clicks and its on. That's always my advice.
