Hi guys,
I have a problem with my Jade. I've charged it last evening and I've barely used it. When I've went to bed it was 96% charged (ARIELbattery) and 10 minutes used.
This morning, when I've woke up, The battery was 33% and and the phone was 34 minutes usage time.
Something is wrong. Since there were no bluetooth, no wifi, no anything activated. And for sure, nobody played with the phone during the night.
This is not the first time when I see this behavior, but is the first time when the decrease is so big.
I suspect an app, but I do not know which of them. How can I see it?
Do you have other suggestions?
thanks!
There are some possible reasons:
Some SD-Cards seem to drain battery, so you can take it out for a test.
Some additional software is told to drain battery. Did you install something?
It is also helpful to switch to "flight-mode" over night. This normally reduces battery drain to nearly zero, if no additional consumers exist.
Hi,
Yes I've installed some software, like gAlarm, S2U2, icontact,ThumbCal, Skype, etc but last night none of them was started.
What can I do with the SD Card?! I need the SD-Card. Which card does not drain battery and which does?
I cannot turn off the phone over night.

I've read those before posting, but there was no answer to my problem. I have 67% drop of battery in 8 hours without touching the phone.
This is most likely that your device goes to screenoff or unattended power state instead of sleep. Your power settings might be corrupted. To change that go to your power settings advanced tab and change everything there (checkboxes and sliders), press ok and then change them back as they were, press ok. I'd suggest to keep the device turning off in one minute while on battery and none of the checkboxes for cord powered mode. There is a really freaky thing that even if you get your device to sleep with power button it will go back to screenoff mode after time specified by the turn off device slider while on battery IF you don't have that turn-off-while-on-battery checkbox checked there.

Thanks for the answer. But I do not really understand what you are saying here.
My power settings are: 30sec for Screen Light and 1 min for Device (on battery).
None of the check boxes is set for the case when the device is powered.
It could also be due to the battery defect. After some time the battery could lose its storage ability (because of the defect), despite the mAH stated.
As a comparison, my battery is nearly one year old. On full charge, overnight drawdown (on sleep mode) is about 2%-3% .

I have no own experiences with this programs but Skype for example needs permanent connection to internet when activated (be care of the background job!). This uses data connection and this drains battery. I can not quantify this in %. In addition Skype does not allow the system to switch to deep sleep because it needs permanent connection!
None of the app was started. I just have Skype installed, but it was not used.

I found some German threads that discuss a problem with this software and battery life. Some loose 10% over night others 50%. I think you should try to uninstall (and afterwards soft-reset!) for a night and see what happens.
Please keep us informed.
First of all, I've disabled the 3G. Now it only gsm with gprs. Since I've done this it seems the battery drop is ... super ok. If yesterday morning I've had 33%, this morning I've had 20%, so 13% drop in 24h, and the phone was used normally as before.
last night the S2U2 was not started.
I will wait until the battery level reaches 10% an I will do a full charge.
I will keep you informed. Thanks to all for advices!

Hi,
So now, 2 weeks later... after setting my Jade to GSM only (no 3G) I get 7-8 days of normal usage. As I said, before I always had to charge it the third day.
Normally, i get -28mAh drain in standby. When the screen is on around -130mAh (for wake up) and then -70mAh. In a gsm call i get around -250mAh.
I did not switch the phone back to 3G yet, but I will and I will see again the battery drain.
PS: the values were provided by Mobadi.
i believe i have S2U2 installed... and my phones fine!
i have the overloaded rom... and battery life seems great only needs charging every 3 or so days and i do use it quite alot!
so...
after some time of testing and re-testing I still have, from time to time, the behavior that during night I see a massive drop in battery level and an increase of the usage time.
I do not know what is going on, but I suspect that some app is waking up the device to do some work (without turning on the screen), and the Jade cannot go to sleep anymore for a while.
I've notice the same behavior on a HTC Diamond 2.
Since none of the app I have installed on my Jade are installed on my friends Diamond2, I have no idea what app could do that.
If anybody has any idea, feel free .... I am idea-less!
I've made myself a little application to log the current values of the power data. So, I've saw that my phone wakes up each hour by himself, without turning on the screen, does some work (cca -70mA) and after 30sec goes back to sleep.
Any ideea about this?
I had everything turned off. No email, no sync, no wifi, no gps, nothing. I fully charged the battery and unplugged it before I left. Display was never turned on. I wanted to see a completely isolated battery test. The only applications I had active according to my task manager was Launcher Pro.
Time on 10 hours 20 minutes
Battery life left 60%
Battery used 40%
Cell Standby - 40%
Phone Idle - 30%
Android System 20%
Calls (1 missed call) 5%
Display 3%
Maps 2% (Why does maps show up?)
Again this is with absolutely 0 use or syncing going on. Left phone at home, turned on and immediately checked stats when I got back from work.
According to this small test I can't even last a day on a full charge even if I left it completely alone.
Thoughts?

In 1.5 day of standby with every radio off and no sim, my phone only lost about 5% with stock JI6.
I think it is a cool idea. I find that 5% usage for one missed call is very bad. I have really suspected that voice calls kill this battery and that seems to add evidence. 5% for a missed call? That is messed up.
I think this is the aspect of battery life that doesn't get addressed enough: drain during standby. Of course everyone expects to lose some power while the display is on and syncing/other processes are running--but what about when the phone is left untouched? Here are 3 ideas:
3g is a notorious battery drain even when the phone is not being used--use 2g instead.
Freeze or uninstall media hub and other running processes that attempt to run/connect to servers in the background. I removed dmservice, media hub, and all drm processes and this seemed to be helpful.
Use a custom rom--these appear to hold power in standby better than stock roms do.

Cell Standby indicates that there is an activity that polls something from the network.
if you are so concerned about what it might be, you can see when and how much data is being used by going to your TMO account online and check for the data usage - one of the good features TMO put in place is actually tell you when your phone connected to get what amount of data over the data connection, does not tell you what it was doing though.
Yeah, something is going very wrong in your phone. When my phone is on standby with just 2G on it drains less than 1% per hour. I would definitely recommend getting rid of the drm service and media hub (and Daily Briefing). I also use Autostarts to keep all kinds of random programs from starting at inappropriate times (Really Slacker, does your app need to launch every time the time zone changes?)

According to Samsung the phone should last 450 hours in standby mode...

I wonder if Samsung's definition of "standby mode" is what the rest of us call "off".
I've never had any kind of batt life with this phone...charge everday overnight...start work at 8, use here and there for navi (around 10 mins max, maybe 2x a day) about 30 min avg talk...and mp3 player...get home by 4 and always at 30% or (most often ) less...have had stock/ bionix roms, never changed, no matter what build....it's pathetic..called tmo, they said there are no known issues with batt on this phone...wow...do a google search on it..anyways, they are sending out a new batt..I hope I just got a bad one...seems very random tho, some ppl have all radios on ,screen all the way up and get 10+ hrs...if i left my screen on (say navi on) for more then an hour straight I'd be out of battery..very weird..praying new batt is better...

Does it seem like youre just not getting the battery life you should from your phone? Do all your other friends keep going while you slowly putter into a shutdown? Well pout no more! Simply follow these steps to clear your batter information from the phone and your phone will act better then new! :)
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot to normal
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"
I turned my phone off today. Then I left the house. When I got back the battery was glad to see me. Seriously, I've read just about everyone and almost started my own battery disturbance thread. I've come up with a new thought at least for me. I don't care any more. I have electricity. I have a spare battery and a charger. If my phone wants to last a whole day. Yay! If I use it more because of some game with angry birds or cards or dice, great. I've reached that Mark Twain moment somewhat tweaked when he said,
“Age is an issue of mind over matter. If you don't mind, it doesn't matter.”
I'll tweak it with the last 27% of battery left in my feeble vibrant to:
"battery is an issue of mind over matter. If you don't mind, it won't matter".
Enough already I say! Lets spare the air. Batteries are meant to be used
Back to the regular reading of all the battery threads now.
I think I had the same issue as you. Cell standby was the biggest drain. When you tap on that, do you see 50% time without signal? If that's the case, this seems to be a bug in Android which was somehow introduced in JI6. The best solution I've found so far is after every boot to put your phone in flight mode for a few seconds and back. This fixes the radio glitch, your time without signal should go down way under 50%, and battery drain should stop. Hope that helps.
You should recondition your battery:
Fully charge
Reboot into recovery wipe battery information
Reboot into OS
Unplug power cable
Let battery FULLY drain (do not plug in until fully dead)
FULLY charge battery (do not unplug until fully charged)
This reconditioning should be done after every ROM flash.
I am LUCKY to get 8 hours of battery life on my brand new stock Epic.. I usually get 4-6 hours. It will NOT last through a normal day of work without putting it on the charger around lunchtime. I take it off the charger around 6:30 AM and I am usually home by 4PM and have to immediately go and charge my phone.
Even if I put it on airplane mode, kill all running applications, and shut the screen off to standby, the phone still seems to suck battery life down very quickly (~5% in 20 minutes on airplane mode, wtf???).. So airplane mode doesn't help.. And I really DON'T want to put it in airplane mode to conserve battery because then my phone is completely useless -- it won't even ring when my wife calls..
Is my battery defective? Please tell me it is... This can't be right..
Are there processes still running that use lots of CPU, even when the stock sprint "task manager" program shows that nothing is running? Is there anything I can do to improve this if I root the phone? How about custom roms? I would really like to run Froyo/Gingerbread anyway.. If anyone has any suggestions to help to make my battery life not such an EPIC FAIL, I would greatly appreciate it.
EDIT: Also wanted to comment on the SLOW CHARGING. With the stock Samsung wall charger, it takes at least a couple of hours to get a full charge. With a USB cable plugged into a PC overnight, it only gets to about 50%. Compared with my previous phone, the HTC TP2, this is really really REALLY slow. It charged in 30-60 minutes and the battery lasted much longer.
I did notice that Samsung only provides a 0.7 amp charger, versus a 1.0A charger for the TP2. Why does Samsung limit the charge current like this? And apparently there is no nueBattery mod driver for android
UPDATE: JuiceDefender looks very promising. Installed the free version and my battery is only down to 95% after one hour. Thanks for the suggestion.
FWIW, I'm getting about the same 8ish hours on mine running DK28. I'm losing about 4% an hour without touching it. I'm seeing some people claiming insane battery life (18 hours with heavy browsing on wifi) I wish I knew how they were managing that.
Wait, it won't even ring when you're wife calls? and you're complaining?
First, the airplane mode means you switch the phone to airplane mode first then switch it back so you won't have time without signal problem which can cause battery drain.
I am able to get 10+ hrs at least by doing the following
1) use airplane mode trick so no TWS
2) use titanium backup to remove a bunch of stock junk
3) use titanium to freeze certain applications (DRM, MediaHub, Qik etc)
4) Have as few applications as possible that constantly pull data
Just yesterday I had 1 day 17 hours before switching
Yesterday when it finally gave up the ghost with the battery indicator blinking i checked my stats.
I had 1 day, 17 hours unplugged. Screen time was around 2 hours and some minutes. I had 45 minutes of talk time.
One thing i will add is I purchased a charger with two batteries off Ebay. Previously when charging with the stock charger as soon as I pulled it off the charger it would read 97%. With the seperate charger it reads 100% for quite awhile before it starts to drop.
And for the record I purchased this charger and two batteries of Ebay for a winning bid of $0.01, plus $9.95 S&H. It was a steal in my opinion.
Unless you are getting near 12 hours of battery life, one of 3 things is occurring:
1) You are using the phone an insane amount
2) You messed something up
3) The battery is defective
For the record, its almost always number 2.
I suggest doing a Factory reset, which will wipe everything off the phone. Then without installing anything or setting your facebook to update every 15 seconds, see how long the battery life lasts. If it is still only 4-6 hours, then your battery is most likely defective.
well of course it won't ring if your wife calls if its in airplane mode. That radio is turned off.
8 hours? That's it? I wouldn't call that normal, but that's just me...
I just plugged my phone in after 4 1/2 days (108 hours) running on a stock 1500maH battery, running Quantum Rom 1.5 (DK17), no special apps running to disable data (aka Juice Defender, etc.), not in airplane mode at all, with the DRM software running, in other words, a more or less 'Stock' configuration (taking into account any differences in the base Rom).
Granted, I barely used the phone in the last 4 days though

Like I said, barely touched my phone in the last 4 days... been feeling a little under the weather so have been at home a lot and in bed doing all my internet stuff and gaming (pogo) on a laptop instead of on my phone.
Since I updated to the leaked Froyo, my battery life has plummeted. It lasts maybe 1/3-1/2 as long as it used to. Turning off 3G has helped immensely though, so that must be the culprit. I used to be able to leave 3G on while at work and make it to bedtime before having to charge it. Or if I shut it off at night (which I usually do), it would make it through my commute to work the next morning. Now, I'm lucky to get through the work day unless I turn off 3G. Huge difference in battery life for me since updating. I'm hoping they fix this in the official release of Froyo.
Well, I've recently found out that if you flash via update.zip while the USB is plugged in, you'll mess up the battery calibration of your device. This is what I did, and i'm pretty sure the cause of my problems. I did find a fix, and here it is:
siliconaddict said:
This is the procedure that works for me:
The following steps should significantly extend the battery life on your phone:
1. Let the battery drain close to empty (5% or less).
2. Connect the phone to the charger (AC or USB, USB is better) while powered on and allow the phone to charge until the notification LED is green, indicating the device is fully charged and untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better. Use a tool like Overcharged or Battery Indicator to monitor this. Note that a green notification LED does not automatically mean that the voltage is good too.
A higher voltage means in practice that it will take longer to discharge, a lower voltage means that the battery will discharge a lot quicker! The difference can be quite significant!
3. Disconnect the phone from the charger and power it off.
4. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
5. Disconnect the phone from the charger and power it on.
6. Once the phone is powered on completely (has restarted fully) wait 2 minutes and power it off again.
7. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
8. Leave the phone on the charger and reboot into the ClockWorkMod recovery menu and wipe the battery stats via -> Advanced -> Wipe battery stats.
9. Disconnect the phone from the charger, restart the phone and start using it as normal.
From then on always let the battery drain close to empty (5% or less) as often as possible and then charge untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better.
Normally you will have to do this only once. However, on all Android ROMs, if you flash a ROM while charging or during the first boot screen on, first boot mucks up the levels Android thinks the phone is at, i.e. Android will think you’re at 100% when maybe you’re only 90% or whatever. So in theory you will need to repeat this every time you flash a ROM while charging!
Better is to make sure the battery is charged before you flash a ROM and just remove the USB/charge cable before you flash a ROM. Put it back in (if you must) after the first boot screen (when the custom screen or whatever shows).

So combining the two bits of info we've compiled, the best way to calibrate your battery is as follows
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery (back button held at same time as power button) and wipe battery stats.
Battery should now be calibrated.

From what I've been told, you don't have to wipe the stats (you need root to do that) but it helps if you can.
I think this may also stem from interrupting the inital charge of the device. I know I did this on both my wife's device and mine (plus my added fubar of flashing with the USB in). Anyway, hopefully I can report some good news tomorrow.

I've been running JuiceDefender for about 5 hours now and I am loving it.. I still have 75% and I can still receive calls just fine.. It turns off data when the screen is off, but turns it on at scheduled times (default is 1 min every 15 min) so that your emails/twitters/etc can update like normal. The paid version has even more features so I bought it..
Never mind im dumb for not reading his post. Already answered my question sorry.

Decided not to quote the whole thing but I'm in the process of doing this right now! Took 2 hours to drain my batt from full (running everything and keeping my phone searching for gps constantly in a place where it would also be searching for signal makes quick work of a battery!).

Yes, with juice defender I can receive calls and my gmail/twitter/facebook/etc. are all already up-to-date whenever I pick up my phone. It works exactly as before, except my battery is not constantly being drained now.
I guess the downsides are that I might not get a new email notification for 15 minutes, and that there is a service running in the background that may cause some slowdown. Neither has been a problem for me so far. I highly recommend this application for Epic 4G owners. Problem solved, basically.
I usually get 12hrs with moderate use (~2hrs with screen on, half of that is usually on the browser). I turn background data off bc I don't have a twitter and I rarely check Facebook so when I do I just use the browser.
I also noticed that wifi burns more battery on DK28, on 2.1 I would hardly lose any battery on standby with wifi, now I get a 3-4% drain per hour... But with 3g on now I lose less then 1% an hour, it used to be a battery hog.
Hey guys just like we all i suffered from the insane battery drain in CM7 with my lovely Vibrant. But yesterday night i found a cure that gives me now great battery life - almost like a 2.2 rom.
What i did?
I googled around and found this post:
1. Open up the dialpad, and type:
*#*#4636#*#*
(the numbers are for 'info'; don't press call, it should automatically go to a 'Testing' menu)
2. Go into 'Phone information'
3. Press Menu, and select 'Select radio band' (this will result in a force close, but that's what we want.. just keep going.)
4. Go back into 'Phone information' and scroll down to the bottom'. It will probably still say 'CDMA auto (PRL)', but the problem is this is probably a visual glitch. Or it might say 'Unknown'. Either way, switch it to something else, then switch it back to 'CDMA auto (PRL)'. Then you can turn off the radio and turn it back on with the button right underneath that.
5. At this point, the fix has been applied, but it would be a good idea to clear the battery stats to get a fresh start. So boot into recovery and do that, then reboot. The fix *should* stick after this reboot, but I think it didn't when I first did it. But assuming it does, then you're golden. It will be like this for all other reboots. If it does not, then just do it again. You can tell if it worked if when you go into battery usage, and go into cell standby, the TWS% is much lower. I charged mine completely overnight after applying this fix and have been off the charger now for over a half hour and TWS% is still at 0% (even though cell standby is at 46% (but that's not a problem at all..), and my battery is still at 100%
My Vibrant gives me now GSM/CDMA auto (PRL) as network type.
So let me know whether it works for you too or not.
For me its asesome, since i can enjoy CM7 all day long ;-)
Seems to be working fine for me, would I have to do this for every nightly.
Sent from my SGH-T959
great find +1 the battery life of cm7 drove me away to a JVQ rom but imma try this find and use it!
I don't know if the cure will work for me, too. I found out that my device doesn't enter deep sleep, so even when I'm thinking it's sleeping, it is not.
The process Android System keeps it awaken. At least it did in #54 and other recent builds. It completly depletes my battery like me drinking lemonade.
Does it sleep for you?
I like this. I can actually stream music while charging without slowly losing charge.
I'm going to try this and see what happens
Hope this gets run through Atinm.

4. Go back into 'Phone information' and scroll down to the bottom'. It will probably still say 'CDMA auto (PRL)', but the problem is this is probably a visual glitch. Or it might say 'Unknown'. Either way, switch it to something else, then switch it back to 'CDMA auto (PRL)'. Then you can turn off the radio and turn it back on with the button right underneath that.
5. At this point, the fix has been applied, but it would be a good idea to clear the battery stats to get a fresh start. So boot into recovery and do that, then reboot. The fix *should* stick after this reboot, but I think it didn't when I first did it. But assuming it does, then you're golden. It will be like this for all other reboots. If it does not, then just do it again. You can tell if it worked if when you go into battery usage, and go into cell standby, the TWS% is much lower. I charged mine completely overnight after applying this fix and have been off the charger now for over a half hour and TWS% is still at 0% (even though cell standby is at 46% (but that's not a problem at all..), and my battery is still at 100%
My Vibrant gives me now GSM/CDMA auto (PRL) as network type.
So let me know whether it works for you too or not.
For me its asesome, since i can enjoy CM7 all day long ;-)

I hope this works, but when i first went to phone info and did radio band, it asked for country, i choose usa, it didnt FC thou, then when my setting was already GSM/CDMA (prl) . I will report back tommorow how it goes. thanks
I'm guessing the same would apply to MIUI?
It definitely seems to be doing something. My signal hasn't dropped below the full four bars yet, which is weird considering it's normally around 1 or 2. The phone also seems to go to sleep faster, but that could be placebo.

yes i tried this it didnt seem to work for me i dont think i got it to stick on im gona try it again
didnt get Force closed at the select radio band. Now what should I do?
on Miui I had to select Turn Radio Off first, then it forced closed and now it seems to stick when I change radio bands. Just turn on/off radio a few times and it should help.

Thanks! Finally I got it to force closed and I did everything else. But I went into cell standby I saw my TWS% is 71 when my cell standby is only 21%. Is that a problem?

I don't know if the cure will work for me, too. I found out that my device doesn't enter deep sleep, so even when I'm thinking it's sleeping, it is not.
The process Android System keeps it awaken. At least it did in #54 and other recent builds. It completly depletes my battery like me drinking lemonade.
Does it sleep for you?

I had this same problem. Apparently alot of others did too, but no one seems to have a solution that I have seen.

Effect of USB Charging on CPU Idle Utilization CM7
First, this test was performed on nightly #55 with KB5 baseband. I have performed this on KA7 as well and found the results to be similar.
I am very sensitive to my battery utilization. In turn, I am also a very frequent charger. Even if I'm at 80%, I feel I must plug my phone in as soon as possible. Because of this, there is hardly a time where my phone is on during a session in which it had never been on usb. This changed, however, this last weekend. I was playing around with KA7 vs KB5, and was away from my computer and charger. Later, when I reviewed my cpu utilization during idle time, I was shocked to see that the phone was just sipping the battery. Less than 1% utilization in System panel.
My initial reaction was "KA7 is amazing." However, the next morning, battery usage appeared to be the same as normal. On a hunch, I wondered if it was possible that it was the charging that is causing issue. As we all know, when the phone is plugged in, cpu utilization is fairly high (~30%), and some even report the battery getting hot (in some cases, even to reboot the phone). But -- is it possible that even after you unplug, there is some lingering "stuff" happening that will not go away, regardless of how long you idle?
What I did was simply charge my phone fully, unplug, reboot. I consistently find that my phone will go in and out of very low cpu utilzation state when I do this. If I go into airplane mode, I will even see full sleep state with no green bars in System panel (not that I would do this, as I like to USE my phone).
I am very curious if some of you may be able to try this experiment and report back. If this is confirmed, I wonder if there may be a way to determine what is getting stuck and robbing our cpu cycles after the phone is unplugged from charging.
Attached are four screenshots:
syspanel_pre_reboot_8hr.jpg: showcasing the long overnight charge, followed by very low activity, yet with >3% cpu utilization while idle. (by wall charge, though this has shown to be the case via computer usb charging as well)
syspanel_pre_reboot_2hr.jpg: a closer look at the idle time after the charge.
syspanel_post_reboot_8hr.jpg: A big picture view of the charging, the reboot, and the subsequent idle time. The first thing I did once the phone booted was download and install several app updates from market. I wanted to stress the phone before letting it fall back to idle.
syspanel_post_reboot_2hr.jpg: here you can see the lower idle cpu utilization on the phone. Initially there is activity as I updated apps from the market, and then it fell to hover around ~1%.
This behavior can be replicated and repeated on my phone every time. I was hoping someone with logcat experience may be able to help me define a filter so that we can see exactly what processes plugging the phone into usb starts, compared to which it terminates when unplugged. If we were to find this, I would suspect it could be added to the code itself.
THAT is what I'm experiencing TOO.
I have tried that fix. When entering the "select radio band" it doesn't force close. I just see "EURO Band" , "USA Band" etc...
also on the bottom it says "GSM only".
Is the fox already applied for me?
I'm using TRIGGER (CM7 based).

no i have the same problem for some reason i cant get this fix to work either
Gave it a try, will see what happens. Battery life is now the only bummer on CM, if this solves it, I'll be a happy guy.
Anyone else encountered this problem ?
I've had my Nexus 4 for 3 days now.
I turn my phone off every night. So two nights for this phone. Each time I have turned it off it has been fully charged, with the battery indicator and a third party app both showing 100 %. The next morning (about 8 hours later) I'm finding the battery has dropped to ~85%, so losing ~2% per hour when powered off.
Anyone else encountered this or know how to deal with it (before I contact Google)
Note - to power off I press the power stud until the Power Off menu appears, select Power Off, then click on OK to shut the phone down.
This is with Android 4.2.1
It takes power to turn the phone on. 15% might be a little much but it is not unlikely.

15% does sound a little high. OP, how's the battery life during daily/normal usage?

Battery life has actually been decent, I think I'm getting better usage than my old HTC Desire Z with extended battery. I'm not a heavy user, though I have been using it for music at work.

It takes a huge amount of battery power to start the phone from complete off, this also skews the first reading of the battery voltage as it will be lowered by the draw of power to start the phone so the indicator will read lower than it's true capacity.
The best solution is just put your phone in airplane mode at night, and turn airplane mode off in the morning, this is more power efficient than shutting the phone down using "power off", and you shouldn't see any battery drain apart from a percent or so doing this.
Regards
Phil
You can tell you guys never turn your phones off Starting up should have no battery drain - never been an issue on any of my previous phones and PDAs (last one also being Android).
I rang Google and they had never seen it before but recommended draining then fully charging the battery.
Friday night I made sur it was fully charged before unplugging and shutting down - next morning on turning on - 99% - result. Saturday/Sunday the same (note SAturday i fully drained then recharged the battery). This morning boots up with just 82%.
Looks like either it can't work out when it's fully charged, else there's some disharge mechanism in place to protect the battery and that's causing me issues.
It probably wasn't really at 100% even it was reporting as such. The reporting is broken. So when you rebooted you saw the real battery level.

I was just about to start a thread on this and then saw this thread here. So I'll ask here. I travel overseas a lot. So while I am on the plane I plug the phone in while off to charge it. I hit the power button occasionally to check the charge and when it shows "Full" I unplug it and throw it in my bag.
2 days later, I come back to the US and turn the phone on and the battery is usually below 50% even though it stated it was fully charged when I unplugged it.
So how does the battery drain if the phone is off?
I just sent my first Nexus 4 in for RMA on this very issue (if left for long enough it would just fully discharge), got the replacement on Friday, did a charge cycle, charged the phone fully up whilst off, took it off the charger (the official Nexus charger btw), and let it sit for the last day, just turned it on, and it's at 60%.... W T F !!!
This is sooo totally bizarre! I can only assume that this is common to most Nexus 4 (what are the odds of me getting two bad ones - direct from Google - with the exact the same issue?), and that people just aren't noticing, as most people don't leave their phones off after fully charging, and thus just never notice, as the battery behaves perfectly normally under usual use.
I would gratefully appreciate it if people could put this to the test, so I know whether or not to RMA the second device or not....

Are you using a custom rom, maybe its only sleeping.
Can't speak for the OP - but for me, no on both devices - totally stock. The latest one, box fresh on Friday! Also, the phone is most definitely OFF, and not just sleeping, ie, I press the power button & choose the "power off" option from the pop up. Unfortunately there's no way to really test this, by pulling the battery...

Nah - I tested it multiple times on my first phone. One time I left it for over two days and the battery went from "reporting 100%" to being under 10% whilst turned off!! Also on all the charges - I deliberately would leave the phone on the charger for multiple hours, even after it was reporting 100%, as I had the same suspicion. Often I'd leave it to charge overnight...
I have never had this issue with any other phone, or with my Nexus 7 (which I have subsequently tested in this respect, and it is perfectly capable of holding a charge whilst off)

It's not so much that it's a practical issue, it's more that I'm worried that it might indicative of a larger hardware based defect, and I'm not happy spending my hard earned cash on faulty goods.
If it's a very common complaint/fault then I won't bother to RMA the second one, but if I'm just ridiculously unlucky, and very few people are experiencing this totally weird behaviour, then I'll take my chances on a third...
Also, I don't think it's too much to ask to be able to turn my phone off to prevent it from losing any more charge. I can think of a plethora of scenarios where this would be extremely useful...
I'm now convinced of three things.
1. Android 4.2.1 can not properly read the battery state
2. Shutting down the phone does NOT do that, but rather puts it in to a hybernate mode that still requires battery charge
3. There is a fundamental design flaw in the phone that part causes this.
Most mornings I find my previously shut down at 100% charged phone at only 80-85%, though occasionally it is as high as 97-99, but not often.
Oh and my ROM is stock, my phone is not rooted.

I agree on all counts apart from the first, as my nexus 7 and my Mum's Nexus 10 behave totally normally in this respect, both on 4.2.1 and 4.2.2 (both stock/unrooted, although the Nexus 7 was rooted/bl-unlocked for a time).
Also, I don't believe it's a miss reading of the battery state, as I often leave the device charging for multiple hours after it reports 100%, by which point it simply must be fully charged. What's more - if you leave the device off for long enough it will fully discharge! The craziest thing is that the phone's battery seems to drain quicker when it's 'turned off", than when it's powered on and sleeping. Seriously WTF.
It must be something to do with either the LG hardware, or LG specific code in the Google ROM. Obviously the phone is incapable of properly shutting down, which is pretty crappy for a so called "flagship" device. As someone who likes to have full control of their device, I find it more than a wee bit irksome, that I don't have the ability to completely shutdown my phone! This is also where the irremovable battery is annoying, because there's no way to test whether it's a hardware or software issue, although I guess I could try a custom ROM and see if it still happens.... however I don't really wanna root & rom if I'm going to RMA it....
I'm really interested to know how many other people have this defect and don't even realise it, because their phone is either in use or charging! I find it hard to believe that I could be unlucky enough to have got two uniquely defective devices in a row...
I'd really appreciate it if people could check their devices for this issue, both on stock and custom ROMs, see if we can work out whether it's HW or SW related...

You could try powering it off with the bootloader. After you power off normally, hold power and volume down, when the bootloader menu comes on use volume keys to select power off and power button to confirm.
I'm hard pressed to believe the battery in my device would fully discharge if left off, when the phone arrived the battery wasn't dead, I got about three hours of solid tinkering before it died.

That's a good point. Mine came out of the box at about 80%.... hmmm. It could be that once it's first turned on it won't turn off again... this is such an odd issue! I shall try powering off from the bootloader next time, I'd still love to hear if other people's phones exhibit this anomaly though...
I'm aware that it's hard to believe issue, but there's only one way to find out...
I'm also very curious to know if loading a custom rom might solve it. I'm far less concerned if it's a software issue, I just don't want to have spend £250 on defective hardware.
I'm 100% stock, no Custom ROM nor kernal (kernel?) and my phone WILL discharge if left unplugged and "off". Happens every time I come back from overseas. Fully charge it up on the plane (even left the phone on but in airplane mode to 100% thinking that it was a misread of the battery level when the phone was "off") and still the same issue... turn it on a few days later and the charge is down to 75% or so....
I thought I was losing it... but I'm not the only one...

Ha - me too! With the first one, I actually went into a weird sort of denial, where I kept convincing myself that I must of got it wrong, it just seemed so absurd! Eventually I put it to the test (multiple times) and realized that my memory wasn't as bad as I'd been trying to persuade myself and the phone was in fact discharging when "off".
Anyone else?
Just got the update to 4.2.2 and have got my fingers firmly crossed that it's now a squished bug... although somehow I think it's more likely an LG/hardware issue...
What you could try to do it charge the battery to 100%, hold the power button for 10 seconds until it fully shuts itself off. Leave it overnight and see the battery level is at the next day.
