[Q] G2 Battery drain during the night - G2 Q&A, Help & Troubleshooting

Hi all, I have a problem with the phone i gifted to my GF. Her LG G2 during the night (only the night!) drains a lot of battery, sometimes even 60 or 70%. This happens both with KitKat and Lollipop, with wifi on or off, with airplane mode on or off. I tried even to reset the phone and install just 2 or 3 popular apps. I sent it to LG support and they changed the battery and the radio but the problem is still here. So I tried to root the phone and I installed setcpu to limit the cpu when the screen is off, and with this method the battery consumption is only of 8-10% (not perfect, but at least better).
So, if I ask LG to change the chipset they will do this? Anybody had the same problem? How the hell is possible that this happens only during the night?
Thanks.

Use an Application like BetterBatteryStats.
Install the apk.
Open BBS and it will prompt you to install it as a System App. Do it.
Charge your phone to 100%.
Unplug your device, turn the screen off and go to bed. (Don't touch your device during the night).
When you wake up, unlock the device and open BBS.
Sift through all the dropdown menu options, and take note of any services or apps with a high percentage.

Fast Battery Drain over night

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.
Some clues here in this forum

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.
Uninstall S2U2 !!!!!

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?

[Q] Battery problem, stand-by

Hi all. Here's the thing. Yesterday i've charge my galaxy (up to about 90%) set up alarm for morning, and going to sleep. In morning my battery was empty, i don't have idea why, because i push power button to "sand-by" on my phone in that night. What's the deal? Stand-up time was about 7h - is there any fix for that, or maybe it's some kind of bug? Oh that was my first stand-by mode for so long time (phone is pretty brand new, about 3 days from purchase)
Few words about phone:
-i9000XXJF5
-no root, flash, and any modyfication
-in phone i have about 20 instaled apps, 4 widgets on
-no task killer
-about 3 days from purchase phone
-home screen set on LauncherPro
Any advise guys?
Sorry for my english.
There must be some app draining your battery. My SGS usually drops only 4% in battery percentage during the night (I turn of 3g at night using SwitchPro, and I'm on JM2).
Have you installed the latest Facebook for Android app? It drains battery a lot because it keeps the phone awake 100% of the time. Uninstall it, or at least Log out from within the app, so that your phone can sleep in idle mode.
Yes... the problems of Android... I use CPUMonitorMini to keep an eye if any apps go rogue and start hitting my CPU 100% and draining my battery dry.

Battery drain while sleeping

Hello
I have a samsung s4 i9500 new phone about 4 months old. I encoutered many battery problems so i installed Arrow rom, which i fell in love with it in a sec, it had everything and the battery life was just amazing. (Thanks to all who contributed into making this amazing rom).
But something happened when i installed an app about adds and it kinda restored my phone yo factory settings, i didnt care much for the reset, but i found out that my battery life ia no longer like before. Let me give you my states before and after.
Ps: i reinstalled the rom hoping better resulta but it was the same
I sleep usually at 1pm and wake up at 10. Thats 9 hours, when my phone was fine it only drained about 10% or 12%.
But as in for today for example, i slept 7 hours and it drained 20%.
Most of the draining came from android oa at 89%.
Please note that before i go to sleep i always charge my phone to 100%
Is there something wrong? Ill do any test to solve mu problem.
Thanks all

Hi.
U should install BBS app and post "other" and "partial wakelocks" screenshots so that we can tell what's eating up yr battery life.
Cheers.
deep sleep!
Yeah BBS is definitely the way to go..also you might want to check skipjack's awesome thread for better batt life when idle (insanely )
http://forum.xda-developers.com/showthread.php?t=2357417
I got better batt life with my s4 after i did some of their tips on this thread..
Sweetdreams to your phone's battery! ))
I have attached my files, btw the battery is kinda weird, one day it drained about 40% but somedays drains way less, keep in mind that when i go to sleep i turn off my wifi and use edge network, and power savor too.
Some solutions that I follow that kind of stopped severe battery drain and got the phone in deep sleep mode:
- Disable "Scanning Always Available" from Advanced settings of WiFi
- Disable GPS and 'Use Wireless Networks' from Location settings menu
- Greenify apps and a few services
- Before putting the phone down for good, clear all the recently opened apps by pressing and holding the HOME button and clearing them all. Then open up the task manager and clear RAM.
- To get the phone into deep sleep (you can monitor this using a free app called WakeLock detector, available on PlayStore), if you have the habit of switching on the screen and then switching it off whilst being in the lockscreen mode (just like you check time quickly without unlocking the device), the S4 DOES NOT go into deep sleep mode even though the screen is switched off.
To solve this, you need to unlock the screen, get to homescreen and switch off screen from there instead of directly locking/switching off the screen without unlocking the device. Yes, it's hell and I don't know why this issue persists :/

[Q] Another battery thread but I am desperate

Hey guys and please dont crucify me. I know there's a ton of other battery issue threads on this forum and on many others but I cant find the right one. I have looked up each and every one of them, about mediaserver draining the battery about the android system and so on. I have done everything each thread said to, downloaded greenify and hibernated most active apps, disabled and froze certain bloatware with titanium backup pro and so many other things. And I think that the battery would be supposed to perform at its best right now. I am not a very heavy user, I just use my phone for music, calls, a little gaming and the occasional facebook/messenger/browser session with either 4G or WiFi. I have everything everyone ever said turned off. Things like auto backup of Google+ and all location services and auto sync. Screen is constantly at 65% brightness. To further prove my point, at this point in this post which took me like 3 minutes to write, my battery has lost 3 percent. I can leave the phone unplugged all night at 100% and when I wake up it will be at 95% but the moment I pick it up and start playing some music or some games the battery goes down really fast. I can even compare it to the battery of my old Xperia S after a year and a half use which was like 7 hours altogether. Battery stats say that mediaserver takes up 20ish% battery and Android system goes over 40%. I really don't know what to do. Do you have any suggestions?
Thanks in advance, George.
you should look at the time it depletes when screen on, if its below 5 hours from 100% downward then its not good. I have noticed the battery still charges past 100%. So leave it an hour after it reaches 100%. I would also recommend using the charger that came with phone. No usb charging for these tests. Dont use phone while charging either.
Also freezing\debloating can be adverse, at least thats my experience on battery life. So I recommend going back to stock full clean with factory resets.
No recovering of apps or app data for these tests. No contamination so to speak.
Also lg roms allow you to switch off services via taskmanager settings, in settings app you can disable what you dont want to use. No need for debloating\freezing etc.
Switch off location settings, gps and bluetooth for this test. Search for carrier iq on lg g2 forum and how to disable it via settings. Switch of cloud storage(dropbox/box etc) and lg backup stuff. Only google accounts, wifi and mobile networks.
Now for the screen on time test, just use browsing apps. No games or music\movies.
Your screen on time should be 6 hours approximately. From 100 to 0. It can be 5-6 hours. If its below 5 then its not good. this is with good network coverage btw.
thats what I would do

Yes I have tried all of the above. Only thing that sticks out is something called 1013 which keeps running and waking my phone but I think it's something about the sound. Next is Android System with many wakelocks and as I said with 30+ % battery consumption. Everything location-wise is off. Actually everything is off. Every setting. Things go to hell when I open 4G or WiFi. Also I have the international model so I don't think there's carrier IQ in my device, or maybe I didn't find it in an app suggested by someone here for that purpose. System Tweaks I think it was.
Could you post a screen shot?

I've had android 4x do this on multiple devices, multiple roms for no apparent reason. Wipe it and start over. Wipe everything. Especially directories with any form of music, sound files, videos... ( Use LG Flash Tool and go back to stock 4.2 for example will do just that )
So the OTA came over to my country and now it seems like BBS and WLD are broken. Can't really do anything to show you the more complex battery stats and can't really say that the battery has improved. Reducing the brightness did have some effect but I am not really fond of having it at such low values. Anything else I can do to minimize the Android System battery consumption? Its bigger than what the screen is using, even when it was at 70% brightness.
Sad to say my first LG G2 just got replaced today & am now running into this problem with the 2nd phone. Its literally night and day battery life performance between both phones.
First phone had 0 issues and by now I'd still have battery % in the 90s. New phone is sitting @ 63% after 3 hours of use (setting up phone, few reboots here there....just factory resetted for the 2nd time to try and clear this etc)
Culprits are:
Google Services
Android Core Apps
Media Server
System UI
Both phones are: 4.2.2
build: JDQ39B
Software: D80110c
brightness (which never was an issue)= 45%
O.P,
has your situation improved or worsened since you've encountered this problem? I'm thinking about sending my replacement back for another replacement

I can now say that the battery life of my phone has improved. But sadlyf the problem was probably some corrupt mp3 files that I moved directly from my old device which forced the mediaserver service to run constantly and thus the android system. :/ I still can say that I think it drains a bit fast when I use it for browsing, Facebook, games and stuff but at least when I check the battery consumption, the only things stated there that make a difference are the screen at ~30-35% and the game which I was playing or for example Chrome. It finally feels like that whatever I use drains the battery and not something else in the background but I don't have that good of an impression for the 3000mAh "beast" battery of the G2. Awesome phone though.

I ended up returning my replacement phone and am back on my original G2 until I can get a proper replacement. I can tell you, the G2 does have an awesome battery life if you get a good phone out the box.
The differences between my first G2 and the 2nd one tmobile sent me are night and day. Get a replacement phone while you still have time.
Should have my new one next week. Just hope it's exactly like my first one.
Ex....been using it all day..I mean heavy usage...and in still @ 75%..and the phone is cool to the touch
The replacement g2 would [email protected] 36-37% by now and running hot

You're on 4.2.2, not 4.4.2 when you have the 1013, is that correct?
Try rebooting when the volume is on, rather than rebooting in quiet/vibrate mode.

The OTA came to my country some days ago. Still the battery feels kind of small. Is it normal to lose 1% every ~1-2 minutes on 4G browsing? With nothing else on. No gps no G+ backup no anything.

Phone Idle under Settings/Battery

What runs under "Phone Idle" on the V20. It's been the largest battery consumer for the last week of use that I've noticed. My wife's V20 is the same and I had my brother check his and his wife's V20.
I'm only asking because I'm not see great battery life like other have been reporting. I don't have live wallpaper, have only two widgets on the home screen. GPS is set to battery save, screen is set to auto but that doesn't even come close to chewing up the battery.
Sadly I feel like I'm still using my old 2.5 year G3 where it'll need a charge mid way through the day.

I agree with you. Although my phone is just beyond a week old and does have all my apps installed, a factory reset can't be the solution here. This is the typical "I don't know how to fix this" answer always given by manufacturers and carriers.

In the roughly 3 weeks I've had my V20 I've only seen this once where phone idle was higher than Screen. I started looking thru all running apps for 'keep awake' time being high and noticed Android OS had keep awake of over 2 hours when it's normally less than an hour after a full day use. I power cycled the phone and it stopped.
The weird thing was Android OS didn't show high battery usage even though something was triggering keep awake. Looks like the keep awake was causing phone idle to be high.
I'd look at everything in your battery usage to see if you have any high keep awake times.

Sorry did not mean to be short in my response. When you set up your phone did you restore it from another phone using the nfc bump thing? I did the same and my phone battery was the same way. Wouldn't last even half a day. After i factory reset and set everything up manually i get 18+ hrs with 7 hrs screen on time sometimes.
If this situation doesn't apply to you then maybe a reset won't help. But you have to understand your situation isn't normal.
Make sure Google now features are all turned off and not running in the background.

I'll have to go through the apps one by one like I did previously on my G3 and see. Now within the battery stats there is only a handful of apps like hangout, play music, chrome and camera. The rest is OS related so that's why I was curious what ran under Phone Idle.

No and sadly I was looking for that feature a week ago but couldn't find it so I had to individually install most of my apps I had on my previous phone...made for a long night along with the additional emails and configuration or icons and such.
I'll keep digging away at the phone...I really want to like this phone ?
Has there been a definitive resolution to "phone idle" battery drain? I just got a V20 2 weeks ago on sale for $360 and its a fantastic upgrade over the One+1 I've been rockin all these years, but I'm also suffering from mediocre life due to whatever phone idle is. Some forums (for other phones) say phone idle is related to your wireless signal. I'm still with the same carrier and frequenting the same locations and had no such battery drain with that old One+.
i finally discovered whats was goin on with me..
i had the same issue..
phone idle was topping my battery usage list
it turns google plays have this "locationmanager service " and locationwhatever" that kills your battery over wifi even with location button off
Go to locations/ 3 dots in top right corner/ turn off WiFi scan. See if that helps.
My phone has been suffering from poor battery life for quite some time now, here are the screenshots, Android OS has been this high on almost all battery cycles.
I disabled wifi scanning as suggested above and will watch the performance, does the community have any other inputs to fix this? View attachment 4212978View attachment 4212979

Phone idle is always the biggest battery draw on my phone too. I have minimal apps too. No Facebook or similar types of apps. I'm on a Verizon V20 stock with the latest security update. Is this normal V20 behavior to have phone idle consume more battery than everything else?
how about doze mode , isnt that meant to help with this sort of problem ? ( my phone is currently on a ship )
Any update. İ have the same problem

So what did you do?
Would also be grateful if anyone shared a solution.
I specifically have a SIM-unlocked Sprint model (LS997) which am using in Europe with another carrier.
Using it in LTE preferred mode drains about 10-15% overnight.
Using it in WCDMA preferred mode drains up to 5% per night (yes, wifi and cellular data OFF and many apps greenified) . So I'm really interested in how this can be fixed and achieve 0% battery drain across several hours.
Or maybe it's SIM-unlocked Sprint ROM related?? I can't root my phone since it has the Feb 2017 patch and is a ZV6.
I suspect rooting it and using another ROM would solve this + the annoying issue of not being able to send images via FB Messenger and Viber while on cellular data (I imagine the Sprint guys placed some kind of restriction to deny media transfer for these apps when using cellular data).
I have noticed this too.. wondered why "phone idle" takes most battery... any suggestions would be great!
I am also curious about the solution. Phone Idle is at top. Even without SIM card. 30% drains during a night (everything is disabled, but no airplane mode is on). I tried factory reset, reinstall older ROM, replace battery, use no app but still sucks.
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :

second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.

following are some advanced battery drain overnight figures of my phone for more analyzing.
