Hi All,
I have been using this device for past 9 months, but recently its giving lot of headache, yes battery drains very very quickly and taking too time to charge 2 hrs I connected and only 15% charged I think it may be due to charger issue so thats not my concern now. My concern is battery drain.
I have installed better battery stats and tried to checked the app which is reason for draining, but im a novice I cant able to interpret the log given by battery stats.
I charged my mobile to 100% and went to sleep and in the morning I had only 65% left, FYI I have disabled mobile data and wifi. I have attached that log here can anyone plz help me to resolve this prob.
And if it helps I have rooted device.
Thanks in advance

Recently my battery life has dropped extremely low. I have been running setcpu to underclock when not in use to preserve battery life and it was working very well draining 1% on standby every 2 hours approx. A couple days ago I had it on standby and somehow in the morning the battery was completely dead after I had fully charged it the night before. It is such a drastic drop and I didn't even change anything that I think it's the actual battery itself. I can watch the %'s drop just watching my phone now. Has anyone else had a problem with this? It seems that the battery can't hold a charge anymore.
Looking at my phone right now, I had it off the charger for about 10 minutes after it fully charged and it's already down to 90%.
The first question that comes to mind is have you made any changes lately? Installed new software? upgraded something? If your phone was getting okay battery life last week and now it's not, it's time to start pin pointing what, if anything, has changed. Keep it mind it is possible for a battery to die...
Someone on this forum told me to erase the battery stats. I was told to go into the recovery. I use clockwork. There is an option to reset battery stats. This worked for me but do some research on this site. I am not an expert but was told to do this by someone who is

Hi guys!
I've bought Arc about month ago and I've noticed a problem with battery percentage, it has oscillations. For example, battery is on 25% and suddenly drops to 2 or 3% and for a while battery is on 18%, or battery is on 84%, suddenly drops to 74% and soon comes back on 85%. I've restarted the phone, repaired software but the problem is still here.
Battery life is very good, average life is 36-48 hours, but there is a problem with oscillation. Can anyone tell me what should I do?
Software version is 2.3.3.
Let me search that for you http://www.google.com/cse?q=Battery...sc.tab=0&gsc.q=Battery problem Arc&gsc.page=1
Hmmm... Why didn't I think of that?
My problem isn't 0% battery or short battery life. Read my post again and than answer me.

Best way to fix it is battery calibrate....but it needs root.
And when it drops and raise 2-3% its quite normal. My Neo doing thiskind drop raise trick when I make reboot and for me its not problem

Hi Sidious
It sounds like your battery are fluctuating more than normal, a drop of 20% is definitely not normal unless you are doing allot of booting and flashing at the same time.
One cause of the smaller oscillations could be that battery is not read as often when in deepsleep to save battery life. It might have some battery level estimations when you wake up the phone that are off by a few % when the next battery reading occur. Might also be temperature changes that also change the capacity slightly.

Arc isn't rooted.

I'm not sure what did you mean by saying that I'm doing allot of flashing and booting at the same time?

Battery sensing module automatically calibrates when it discharge from 100% to 2% or lower. So, let it discharge a few times to 2%, and try to do a light use (no games, etc) doing this, to help fuel gauge module to detect internal battery impedance and correct the % marking.

Hi Sidious
If you had the bootloader unlocked and was flashing new kernels or firmwares. I have noticed that the phone when in "fastboot" mode do not charge but consumes allot of battery, it usually shows as a sharp drop when the phone are booted up. "fastboot" can be used to flash new kernels on the phone, but I do not think this is the problem in your case when you are running the SE provided firmware only.
Hi guys I know battery issues are covered a lot but this is slightly different.
The past couple days my battery has drained a lot. Within 6 hours usually its a minimum 7 hours until it reaches 20%.
But since yesterday Android System has been partial wake lock, according to battery use it was 50%. It was only till I rebooted earlier this afternoon that it was cleared but saying that the drain after a full charge ive been on battery for 3 and half hours im already on 53%. Should I use battery calibration app to remove battery stats? Im not sure if I should as once I reach 90% the battery stats reset itself.
Im on stock rom rooted latest firmware.
Thanks in advance

Hi guys, I just got my galaxy note II for like 2 weeks ago. And i've noticed a problem about my phone.
My galaxy note II will drain the battery for like more than 20% ( 20%-25% ) while its in idle. Which means after i fully charged my phone, i unplugged the charger and i used it for awhile more like it was left 92% before i slept. Then the next day when i woke up i noticed that my phone's battery drained about 20++%, it became 79% (i slept for 8-9 hours). I didnt leave it with wifi on. I just left it with 3G & power saving on!!!! This is a serious problem, i mean how is it possible to drain for 20% just for around 9 hours of sleep.
And one more question, how long does your galaxy note II battery last after a full charge with you playing checking the phone for message once for almost every 20 mins?
Normally i woke up around 9am for work and by the time i reach home at night around 12am. It still has around 30% of battery. But today, this strange thing happened. I unplugged my phone around 9.30 am. Starting of the day was okay, it was normal. But right after it was reduced to 60%, the battery started to drain faster. By 8.30am it was already left 25%.
:crying:
GUYS HELP PLEASE!!! AS IM NEW HERE. REALLY REALLY NEED A SUGGESTION ABOUT WHAT TO DO TO MY PHONE.

Yes the battery does drain even as you sleep. Keeping 3G on actually drains more than Wifi. So if you really want to preserve your battery overnight, turn off your mobile data totally. It is somewhat an annoyance that you can't choose between 2G/3G like you do with iPhone. If you still want that connectivity, leave wifi on instead of mobile data.Give it a try for one night and see how it goes.
Are you using any power saving apps?

I just tried again last night and it drains from 100% to 81% from 8 hours of sleep? Is it really normal?
I am using this app callee "cpu spy". Over 8 hours of state time. Only 5 and a half hour my phone is actually in deep sleep. 200mhz for almost nearly 2 hours. And the rest go to 1000mhz and 1400mhz. Do you understand what it means? I dont. Can you please explain?
And im not using any battery saving app. Any suggestions?

Post some screenshots of your battery usage.
Strange, for me the battery is quite long lasting. What application is draining your battery?
Attached my screen shoot.
Sorry for the chinese menu.
Follow the link in my sig towards How to flash a custom rom (no i am not asking u to flash one). U will find one tab for useful links. That thread can help you debug your issue as well as suggest probable solutions.

Under where it says screen usage 48%, click on that to further expand on that. Then post that screenshot.

You can change between 2g and 3g.
More settings > mobile network. GSM is 2g and wcdma is 3g.

Op have you installed viber by any chance? This app drained my battery quickly even when I am not using 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.
