Hello guys,
My optimus g does unusual battery drain during deep sleep. Before about 2 months the battery consuming in a sleep of 8-12 hours was max 5%. Now after a sleep of 6 hours its draining 15%(!!!) with only WiFi on. My phone seems to be awake 8% through wakelock detector and the only apps that shown by Gsam battery monitor that using battery are Kernel(Android OS) for 21,5%,Google services for 6%. I am with stock rom and kernel no rooted.
Any solutions? thanks in advance.
Hi
I am having this problem also. At first of July Google Play Service were updated, and from then my battery goes as yours. I have tried all except hard reset. In internet I have found many threads that talk about it, but none has the trick for me. I am desperated. I am waiting for 4.4 in my device and will see.
Did you find any solution for this problem?
Regards
FermÃn
I got 4.4 before one week and now the battery is way better than before!

Hi!
I installed blackout ICS incredible in my DHD. Everything went well but I wanted to calibrate my battery.
So I downloaded Battery Calibration by NeMa from Google play. Before calibration my batterylife was about 12-24h depending on my use.
Now after the calibration my batterylife is about 5h!! And the same usage as I have always had, couple of calls, net surfing and maybe a little of Angry Birds and spotify.
Did I do something wrong or is my battery dead? My DHD is about 2 years old.
According to Google calibrating your battery (erasing your battery stats) doesn't actually do anything, so it shouldn't have made your battery life shorter. You could install BetterBatteryStats from a thread here on XDA to see if something else is eating your battery. Look at alarms and wakelocks.
Ok, thanks. I installed the BBS and I'll tell the alarms and wakelocks here if I don't find anything funny about them...
bananagranola is right.

calibrating your battery basically tells your OS how much batter it has or doesn't have. IF you flash a rom at less than 100% battery, then the max amount of battery your OS thinks it has might be different from how much your phone actually has. Sometimes this can affect battery life.
The other thing is, did you calibrate at 100%, then unplug immediately? If not, that might trick your OS into burning your battery so quickly.
Otherwise, 12hrs to 24 hours is super amazing, I'm a semi heavy user, and I'll only be able to get 12-14 hours of semi serious use (8 hours standby, 2 hours on off usage, some of that at 100% brightness when i'm outside, and lots of music), end of that I have only 32% left. 24 is pretty amazing, I wouldn't be complaining :laugh:
Well when you simply reboot new stats are generated.

Ok, so I have had today the BBS running on the background. I tried one thing in afternoon, I switched of Wifi. Wifi was off about 3h and when I came back to home I switched wifi back to on. I have still 70% battery!! and about 12h without charging.
BBS alarms:
android, wakeups:83 (Is this much?)
com.google.android.gsf, wakeups:56
com.android.settings, wakeups:13
and the rest of them is under 10
BBS Kernel Wakelock:
wlan_rx_wake: 14m18s
PowerManagerService: 10m57s
and rest is under 4mins
BBS Partial Wakelocks:
AudioOut_3: 3min16s
Twitter sync: 1m56s
BBS Other:
Deep Sleep is about 10.5h
Wifi On/running is about 6h
Is there something wrong or is there something that uses too much battery? Could the battery be "damaged" due it's about 2 years old now?
Sorry for stupid questions but I find it very annoying that sometimes battery life is 5h and sometimes it's way more than 12h with same usage.

What you've got looks fine (which makes sense, since you had good battery life this time). Keep BBS installed. If/when battery life starts tanking, take a look at BBS and see if anything else pops up. If you've got more questions then feel free to post again here.
Although you might miss the customizations of the roms, aospX has great and I mean great, battery life.

Hi everybody.
I have had the optimus g since september, the european version (i'm from italy).
The rom is stock and the android version is 4.1.2.
A month or so ago, i found out a problem with a wakelock, so i installed better battery stats in order to find the culprit.
After uninstalling the app responsible for the problem, i started doing some test with better battery stats.
I found out that my phone when in deep sleep, without airplane mode drops about 9-10% per hour, while if the airplane mode is on the drop is of about 6-8% per hour.
My phone is rooted and i use greenify, keeping almost every user-installed app hibernated.
Reading in the forums, a lot of people write of drops from 2-3% per hour, so i've been wondering if you could help me with this.
Thanks everyone, pierval
last night I had fully charged my m8 and when I slept at 12 it was 95% and morning when I woke up at 8 it already drained up to 15% battery ..that is 80%...I don't understand what's the reason for it ...no apps were running background and even power saving mode was on!
battery works great on normal mode..this happens mostly in standby mode!!
is anyone facing the same problem or I m the only one. .

Is there anything that could have been turning your screen on during the night? That sort of drain would most likely be caused by the screen. Has this happened before? It could be an isolated incident if not. Also, if you used extreme battery saving mode I doubt you would have had the problem, but that is a personal preference sort of thing.
Also, install GSam battery monitor and you can check what might have been going on when the drain was occurring.
Yes, need gsam screen shots. Or every reply will be a wild guess. And you need gsam root companion.
Hopefully you are rooted tho... Or you can't see the wakelocks from apps.
Im having big battery drain with those 3 wakelocks:
ril-fd,
powermanagerservice.wakelock,
bam_dmux_wakelock
I have 4% activity level with Wakelock detector which is better than 19% that I started with but still not perfect.
During the night I had "PhoneApp" draining 11% of my battery, it has vanished after reboot, will check it again tomorrow morning. Im gonna drop some print screens a bit later but can someone please help me with those 3 wakelocks?
I read on this forum that those wakelocks might be contected to Fast Dormancy but came to conclusion that its not present in 4.4.2 KitKat? is that true? If its not there maybe that the issue? is there a way of acquiring it?
I am seen huge battery drain on Nexus 7 2013 after flashing Android 6.0 factory image. Even battery usage option screen gives strange result. For example -- Total battery % used by all the apps just show 9%, while total battery left is only 73% after fully charging of 100%. So where is the remaining battery of 18% gone, which is not even showing up in battery uses option screen?
Attached herewith is screenshot of battery usage screen. And I really notice huge battery drain with Android 6.0 as compared to earlier Android 5.1.1.
Please help and let me know.
You're estimated time left @73% is 3 days, which means your tablet has been on and not charged in awhile. Nothing in your battery stats indicates any battery drain at all.

It just says 3 days remaining. But practically this never happens. Now overnight there is 30% battery drain without having used the tablet and it says now 43% battery remaining and one day left. And total usage mentioned by apps in battery usage screen is not even more than 15% now also. And if you add actual battery usage of all apps by clicking the indivisual battery usage details, total usage is not even 500 mAh. I believe Total Nexus 7 battery capacity is around 4000mAh.
So where is the battery use and drain is happening? This behavior I am seeing is after upgrading to Android 6.0.
I've got quite a bit of mystery drain as well. It runs flat for a little while when the display is off and it is idle for a long time, then suddenly it will just start draining ~2% per hour. The wifi lists as always on even though the policy is "Never". I have location services off, bluetooth off, NFC is off. Even more fun I put the tablet down 2 days ago at 75% battery and I picked it up this morning I picked it up and it was dead. No battery log at all either.
Hmm. I'm running stock rooted with ElementalX, and haven't had any battery issues.

Exactly the same issue here. Battery drains fast but battery stats shows no abnormality. I work for an Android phone manufacturer. My colleague who is in charge of the battery thing guesses some hardware module might have current leakage in sleep mode which software cannot detect.
I have wiped cache partition and now see massive battery usage by WiFi after overnight. Looks to be problem stated in the thread https://productforums.google.com/forum/#!topic/nexus/NB0izQHuBaU;context-place=forum/nexus
Though this issue is raised for Nexus 5, I think it applies to Nexus 7 2013 Android 6.0 also.
You are not alone. My Nexus 7 is currently chewing through it's battery at a rate of knots. Even with the screen off it continues to use the battery as if it were on all the time. After wiping the cache partition things have become even weirder. Apps that have not been opened are using large percentages of the battery. I can barely get a few screen hours out of it.
Wondering if this thread has so few replies because people are checking the general section and seeing nothing about the issue so think it's just them?
The information on battery usage is so weird it's hard to believe that it's producing any useful or meaningful data.
Even I am surprised that no battery drain issue for Android 6.0 is reported for Nexus 7 2013 in this forum and not many members have replied to this thread.
Anyway for me it is a serious issue with absolutely no advantage in any sense for upgrading from Android 5.1.1 to Android 6.0 for Nexus 7 2013.
Here is one more screenshot of battery drain with no battery accounted for 27% (48% total battery drained - 21% battery used by apps reporting in attached screenshot).
I hope at least Google Android team is aware of this issue and knows how to resolve it.
Still amazed that there are only a handful of replies to this thread.
Got the System Update notification today. Size is of 2.2 MB. Downloaded but unfortunately battery charge was not enough to do the OTA install. Will charge the Nexus 7 2013 and install the OTA update. Let us hope that this OTA has fix for this battery drain issue. Will check and let you all know tomorrow.
Even new factory image for Android 6.0.0 build MRA58U is available now.
Same issue of battery drain with MRA58U OTA update also. 20% battery drained out during night within 7 hours when Nexus 7 2013 was idle without any activity.
Same issue here. Flashed 6.0 last weekend. 2/3% idle drain an hour while everything (bt, location, syncs, nfc) is off except wifi. Wifi keeps connected while set to go off when screen off. SoT off course hours less with the idle drain.
Same Issue battery Drain
Same issue battery drain ....i hope the lattest update send me by OTA this week resolves the problem...
I'm seeing great battery life now without root and Greenify or any third party solution but I have problems with the stats. If I let my n7 drain completely and charge it to 100% while shutdown I get +10h SOT (lowest brightness) but if I charge it from 1% without being shutdown I only get 8h SOT. Huge inconsistency in the stats, it's like the system misinterprets the stats and need a reset after every charge.
Hi!
I'm having the same problem with huge battery drain in sleep mode with my nexus 7 2013 after the update to android 6.0.1.
It is using 2-3% of battery per hour when in sleep mode, but the problem is, nothing is indicating what is causing this drain (in battery usage stats everything show as normal - no huge battery drain by the app or wifi, but something is still draining battery).
Prior to the update (Android 5) i was losing maybe 5-6% per 12 hours at most (cca. 0.5% per hour) and the tablet would last 3-4 days, now I have to charge it almost daily.
Any more news on this issue or possible solutions?
Thanks.
