My battery life suddenly became horrible this morning. Normally I unplug my phone every morning around 6AM, and i dont need to charge it again until closer to 9PM.
This morning, I realized that despite being on a full charge at 6AM as usual, my battery was completely depleted by 10. I checked the battery "app" and it said that phone idle and cell standby were both at 13% usage, and that was the most i had used my phone. it registered the full time (4 hours) of usage for those 2 but it also said that it was only responsible for 13 % of my battery drain each. After that there was google play services.
I figured it was just a fluke, so I reboot the phone and recharged it. Once again, the battery drained in a mere 4 hours. This time it told me a voice call of only 10 minutes length was responsible for 35% of my battery drain, and that having my screen on for a seperate 10 minutes was responsible for 25% of my battery drain. This might be fine and dandy if the actual draining chart showed a steep fall off when i made the call, but that is not the case. the chart is a straight line showing constant drainage with no steep or flat areas. I'm thinking something is definitely wrong and the phone is causing itself to drain. maybe something hardware oriented, since i dont even have very many apps downloaded.
I've literally only interacted with my phone maybe 3 times today, and I didnt even do anything major.
Do you guys have any ideas as to what is going on with it?
I'm CM10, latest stable. not the monthlies. no cpu hacks or anything, and as I said, this problem cropped up this morning. before this everything has been fine.
Please search for Better Battery Stats here on XDA. That thread has quiet a few tips on saving battery drain.

If I hadnt already made sure I was following the tips and I wasnt dead sure that something was the problem, I would not have made this post.
I did manage to figure out the problem by sheer dumb luck and a little bit of educated guessing.
I uninstalled the MyFitnessPal and tried again today. I'm exhibiting normal battery drain now (10 hours and im at 46% with not too much usage of the phone).
If you read the post I made, no apps were showing up as a large battery drainer, and all my stats were reporting incorrect times (13% battery usage for a 4 hour period despite showing me i only used the phone for 10 minutes). So something was definitely wrong. Uninstalling the app fixed the issue though, so for anyone who exhibits this problem, uninstall whatever apps you most recently installed and do a reboot.
I didnt have to reset or anything.
Hi guys,
I'm having trouble getting through the day with this phone. I have a new Anker 2200mAh battery that I've cycled about 3 times now. I am running BeanStalk 4.4.4, and I have few tweaks like, Memory Manager (cause it keeps freazing, running out of ram), Entropy Fix app (at ~512, which doesn't seem to fix lag, but not sure), greenify and Amplify, related to battery.
But I'm still draining about 6%/hour on mobile data. This is not normal right? It's really hard to get through the day with this kind of battery life.
So what do you guys do to get about 1% or 2% drain per 1 hour in standby on mobile data? I'm using Xposed, and I greenified apps that greenify says wakelock a lot.
I would really appreciate your help!
Thanks.
BTW, I'm pretty sure it is not normal because in Amazon website, this anker battery has full of satisfied reviews saying it lasts a full day/ 2 days with this battery, but for me, even with this larger battery, it drains very quickly in standby.
In addition, when screen is on, I get about 1%/2.5 minutes in mobile data at 50% brightness. I think this is fine. Am I right? For 100% drain, this leads to 250minutes, which is slightly over 4 hours screen on time. This is on mobile data, so I think it's pretty good, but I'm not 100% sure.
But because standby drains quite a lot, I'm not even able to get over 2 hours screen on time.
I don't have wifi at work btw.
I hope someone helps me soon. Thanks!
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.
Nexus 7 2013 lte android 6.0.1 battery drain for me....
+1
I just turn off the wifi icon from the Quick Settings.
6.0.1 nexus 7 2013 wifi.
I downgrade to kitkat 4.4.2 and my nexus after 24 hours in standby only drain 12% battery......the problem are android 5 and 6 the tab work great and faster whit kitkat no lag or other problem
Very bad google policy
Reading through some battery threads I was told that the "proper" way to check your overnight drain was to charge up to 100% and not touch it until the next morning. I tried this last night and WiFi drain was in the 30% range (I used my phone before taking the screenshot which is why it's at 22%) with a total drop of 7% (100-93% over 8 hours).
Does this seem high?
I've got WiFi, NFC, battery saver location, mobile data, and double tap to wake on. The phone is rooted and I'm using a custom kernel (but I'm pretty sure it happened with the stock kernel too). I also have an Android Wear watch attached all night. On AOSP ROMs on my OP3T overnight drain was around 2% if I started at 100% and WiFi was never more than maybe 6% of total drain. Again, I'm not asking how to fix this, I'm just wondering if this is something that others are experiencing.
Thanks!
Mine dropped 2% over four hours of sleep. I'll try with battery saver on.
Mine averages about 3% in 8hrs with wifi on, I'll post a screenshot tomorrow, on freedomos using simplegx kernel
My WiFi drain is very low during idle. Like most flagships of this era.
mine is as same as op, but last night i charged it upto 74 and slept and when i got up after 6 hrs or so it dropped 2 %, strange ... maybe it's the way the phone is charged and calibrated for dash charging
I'm loosing 4-5% in 8 hours.

Thanks for these screenshots. Obviously I don't have nearly the SOT that you do in my screenshot, but it looks like if our SOTs were the same you'd probably have similar WiFi percent usage.
Mine's been surprisingly bad - at least, worse than my Moto G5S, Galaxy S8+ or iPhone 8 Plus were. I'm losing like 5-7% every four hours, my battery drain while connected to wifi at work is way worse than either of the other phones mentioned too.
All in all it's kind of disappointing considering how good the OP5T is in literally every other regard.

We may have similar WiFi usage. But my drain is about .5% per hour, overnight. I don't consider that high, and battery consumption has to be attributed to something. Here is my current usage since yesterday's charge.
On 8.0 the WiFi drain % is even lower, but idle drain per hour is the same. So it doesn't really matter.
Very bad.. Battery go. Down quickly in night..
My wifi drain is also really bad on the latest 4.7.4
Hope they release a fix soon...
Edit... I did a fresh install with stock 4.7.4 and it isn't as bad but still is present. At least it's more tolerable.

So I did another test last night (4.7.4 and SimpleGX kernel) and had 3% drain. With all the comments here I think the high percentage of WiFi is normal and probably not affecting battery life a lot. I am starting to think the kernel may be providing better results than stock 4.7.4 though since a lot of people are mentioning poor battery on 4.7.4.
I don't even know how long, all I can say is my battery drains 3% every 9 and a half hours. Both bluetooth and wifi was on. This is on the stock rom and kernal, not sure how you guys have such high battery drain... Are you guys sure it isn't another app hijacking your battery? Because from my experience the battery stats isn't always perfect. Sometimes I was told that it was my screen (on my old phone) in which it was actually a 3rd party app. After removing the app, my battery drain went a lot slower than usual.
Has anyone tried this toggle in Developer options?

Just tried that setting last night and it doesn't make much difference.
For all wondering I have an Android Wear device connected 24/7 and location set to battery saving. I also keep NFC and data on all night. I'm not using screen-off gestures though.
I wish it was only 7% or something like that on my OP5T.
I used to be one of you 3%-battery-"drain"-at-night-guys, until the official update to Oreo. Now it uses 36% in 6h38m, of which WiFi is reported being 29% (1044mah, despite 0m active and background usage reported). There is 2.8MB additional use according to the WiFi data usage report that was set to count from today, yet the numbers per app have decreased, so there goes reliability on that. I haven't added or removed any apps, only wiped cache after the update. On standby, it only takes 18 hours for it to drain, which used to be several days.
Another weird thing is that WiFi is terribly slow since the same update, but only on this device. (No numbers yet)
Right now my plan is to test all the mentioned related settings, as well as WiFi off, make screenshots after each nightly test, and finally do a complete wipe and perform the same tests with a minimum of apps, and then redo them again with my usual set of apps. It could still be one or more apps that misbehave on Oreo specifically I suppose, so if there's any indication for that, I will start eliminating apps one by one until I find the culprit.
I haven't been able to root my last few phones so I wasn't able to really use Greenify recently (i mean I know I could use it in non-root mode, but I never cared for that and found that to be kind of buggy)...
With all the battery improvements supposedly implemented as Android has continued to evolve, do you think that Greenify still offers any benefits?
My standby drain is not so good -
According to EXKM My idle drain is somewhere around 3-4%/hour.
According to BBS, so far today out of 5 hours 30 min on battery, I have drained 5.2%/hour, down 28% in total, with almost 3 hours of deep sleep (54%), 1 hour 23 min of screen on (25%), and 1 hour 5 min awake (w Screen off) (20%). The 1 hour 5 min awake seems high to me - I did listen to 15 minutes of music so that would explain 15 minutes of it.
I checked out my partial wakelocks and the highest is ImsSenderRxr.
According to Battery Usage in settings #1 is Screen at 1 hour 23 minutes (that's good it is first), #2 is Google Play Services which has used about half the same amount of battery as the screen, #3 is Ambient Display which has used almost as much as play services.
I'm going to try adding Greenify and see if that does anything beneficial, but figured I would ask the community to see what your mileage has been like with Greenify more recently since it has been awhile since I've used it.
Honestly, I haven't found much of a need for Greenify, aggressive doze, or wakelock blocking apps on 8.0 and above. It might be beneficial to Greenify battery hungry social media apps (especially those related to Facebook), but then you end up with Greenify running constantly in the background. Plus it requests usage permissions, enabling it as a device admin, etc.
Do you have Adaptive Battery enabled? There is a thread in the general section where a few users have reported that their battery life improved after disabling it.
I came here wondering the same. I had Greenify installed for a while but im not sure its really doing much anymore. I just took the lastest OTA update and im gonna roll without Greenify to see if there's a difference. Ill report back in a few days.
I know it's the wrong phone. But I have just bought a Pixel 3a and am introducing myself to its battery usage. I use Greenify on my Galaxy S7 running superman rom. I forgot to reinstall it last time I reinstalled things and I reckon it makes between 20% and 30% improvement.

My idle drain using EX is usually around 2%. What is your charging behavior... overnight and leave with 100% in the morning? I leave mine on the Pixel stand all night. If you are keeping it in your bedroom off-charger, use flip-to-shhh. You should have done that with BBS. If you didn't run BBS again overnight. 100% charged, hot off the charger and flip it upside down. This is just for a proper overnight battery drain test. Second, I would install Accubattery. It is NOT a battery drain app, but rather will eventually zero in on your remaining battery capacity compared with new. It uses several full charging sessions from say above 20% all the way to 100%. After a few full charging sessions it will give you solid information the condition of your battery. Just ruling the battery out here. If Accubattery confirms your battery capacity is well over 90% then you may want to do a fresh install. Sometimes that is the only thing that is going to return the good idle battery drain. Just my .02 cents. Take it for what it's worth. For reference, my battery capacity started at 106% new and is now at 94%. Cheers!
