What is your idle battery life and setup with JB?

I'm noticing my idle battery drain on JB is slightly higher (but not significantly so) than it was on ICS. What is your idle battery drain % per hour on JB, and with what setup (ROM, kernel, # accounts syncing, etc.). Could this be entirely due to the "update location" checkbox in Maps (possibly for Google Now)? Any other potential causes?

The first night with Jelly Bean my phone went dead overnight (from about 51%), so I went through my settings and found that it was Google Now and/or the location updating in Maps. Probably contingent on one another. I turned Google Now off and unchecked the "Update Location" settings and the second night it only lost 4% battery in 9 hours.
Note: I also had GPS turned off during that first night so I don't know if that caused higher drain but I'm going to wait to see if it will be addressed in a future OTA before using it again.

I am actually conducting a bit of an experiment to find out more about the battery drain. Im in school so my phone spends a great deal of time on idle as I work. Yesterday I got about 22hrs of battery life with 2 hours of on screen time and some light web browsing, only sync accounts is Google. That was with stock Kernel and BAMF's JB build. This was about the same, maybe even better than my stock ICS 4.0.4. However I flashed James Bond kernel (3.1.9.9) and was pulling 1day 15hrs average with the same kind of usage (maybe enven a little heavier, didnt take screenshots unfortunately). Currently I have Franco kernel (r220 384gpu) loaded and overnight with 4g left on for 8 hours I dropped maybe 5% max.
I have no reason to go back to ICS so I wont do more testing on that front but I plan to try some kernels on the rom I am currently using.

For last night only 3% for 10 hours with wifi is on.

So idle drain used to about half a percent per hour, today during work it has been 1%+. I noticed the "Keep awake" time under Android OS is over 2 hours even though screen on time is only 40 minutes. This is likely the problem right? I heard about possible issues with Light Flow on JB but I'm not sure if that would show up under Light Flow usage or Android OS. What are some other possible causes for the keep awake time here? Specifically related to Jelly Bean.

My battery drain has remained constant over the upgrade, I am getting about 2 days of battery life on idle, about 1 day on heavy usage.

Anybody else? My idle drain is now consistently at least 1%/hr or slightly more, whereas it used to be half percent/hr. I'd like to know what is causing this increase. Should I turn off Google Now? Are there apps I should try that will tell me? My Android OS keep awake time is still almost 4 times what my screen on time is...I don't think that was the case on ICS. What are other people's keep awake vs. screen on time?

Currently I have about 1hr 10min screen time and OS keep awake time of 7hr 33min. Total time on battery is 1day 2 hours and I still have 35% It seems that the kernel included with the Vicious build does not fit with my usage habbits and will be loading the James Bond or Franco kernel I had before. I feel like they had better deep sleep and governor management for my usage.

My current usage and stat on stock: 1d 16h 30m, 48% bat, 1h58m on screen with wifi is on. it's amazing

Ok, so yesterday I installed BetterBatteryStats. My phoned was unplugged for about 17 1/2 hours, screen on time less than an hour, and the Android OS "Keep awake" time was 15 hours and BBS showed Awake time as the entire 17 1/2 hours, and no deep sleep at all. However, I checked the various other things (wakelocks, processes, etc.) and even the highest item on each list didn't show more time than 10-15 minutes.
So I rebooted, checked several hours later, and it was in deep sleep for 90% of the time. That's good to see, but the issue is the no deep sleep thing keeps happening.
What can I do at this point to figure out exactly what app or process is preventing deep sleep? I've searched around and haven't seen many suggestions beyond BetterBatteryStats, which isn't showing me any major offenders.

I was thinking the same thing as you just as I was getting ready to charge my phone and wondering why Phone Idle + Maps were a third of my usage. I had 131 hours (32% remaining) on battery with 30% idle and 3% Maps, 33% screen with 2 hours 27 minutes on, 2.5 hours awake. I didn't start noticing this change until the last Maps update and turning on Google Now location stuff. Better Battery Stats also showed an awful lot of wake-ups each time I went to look before charging.
I also didn't notice this problem with 4.0.2 before I made the jump to 4.1.1 so it will be interesting to see if our increase in idle/Maps consumption is because of our Google Apps wanting to know where we are and if other users notice the same thing when they get upgrades - be it community or carrier based.

[Q] Battery drain in deep sleep.

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
Fermín

I got 4.4 before one week and now the battery is way better than before!

The Battery Drastically Drained in seconds!

Hi guys. Im new here. I just wanna share about my Z1 compact latest battery problem kinda frustrated me lately.
I bought the phone 2-3 months ago, already with Android Lollipop 5.0.2. Since the purchase, I didnt really face a problem with the battery life as it lasted about 12 hours per charge due to my heavy usage of the phone.
But a few days lately, my phone being worrying me as the battery doesnt being as normal as always. For example, it can drain the battery drastically from 88% to 67% in a few seconds when the screen is off (in standby mode). Sometimes, in the middle of the usagefrom 39%, the phone suddenly shows the battery low warning with a 1% battery remaining, and without having enough time to reach the charger, it shuts down by itself.
In rare cases, I caught my phone drained the battery drastically when the screen is still on from 15% to 1% less in a minute.
The phone wasnt rooted and I didnt anything else besides my daily normal usage. The latest apps I downloaded before the problem occurred is Waze.
I tried everything to save the battery like using the Stamina Mode, force stops some apps, slides away all of the running apps in the background but failed. I even factory reset my phone and installed all the apps the way it used to be but still didnt solved the problem.
I still have about 8 monts of Sony warranty but I need you guys help first because I need to use my phone for work right now. Please help and reply.
Thank you. *Sorry if my English isnt that good*

When the battery jumps from 39% to 1%... Does it stay a long time at 39%? Or from 39 to 1 in few minutes?
Just curious...
Sounds like a warranty issue to me. You could try to find out what is causing heavy drain like with BetterBatteryStats. But no app ever should cause such drains.
Sound more like your battery is not okay.

welcome to the battery drop bug

The exactly same problem with me .I have 100% battery and indicator stays 100% for a half hour than drastically drains to 1% and shuts down.

Change your battery! I had the same Problem. I changed my battery with anotherone original from Sony, but a few weeks later the same Problem: quickly battery drain.
So I ordered me a battery from e-bay but NOT one from Sony! Now a few weeks later still NO Problems. Everything runs Ok now. NO battery drain at all.

HTC 10 battery issues

Hi everyone, I am running HTC 10 marshmallow stock rom (My country doesnt have nougat update yet) and I faced some problem with the battery recently. I went to travel in iceland for about 2 days, and after i came back I realised a rapid drain in the battery power even during idle.
Below are a few tests that I carried out,
1. I charged my phone to full and carried out the default battery test by typing *#*#3424#*#*. The results was 6% of battery drain with screen on for 1 hour at maximum brightness in airplane mode. From the htc 10 customer service team, they said this shows that the battery wasnt faulty ( The battery is faulty if battery % drop below 70% in an hour).
2. Then i switch to safe mode to check if it was the background apps that causes the problem, even worst, the battery over night in extreme power saving mode was dropped by about 40%. I factory reset the phone.
3. The next day I do the same thing as (2), but this time with airplane mode, the battery drained over night still about 40%.
The battery usage from GSAM apps shows nothing unusual going on in the background at night.
I have to charge my phone at least twice, once before i sleep and once after i woke up, i sleep average of 7 hours a day.
My question is, since its not battery issue, after i factory reset the phone this problem shouldnt persist, can somebody explain to me before i decide whether to send in for repair? Sorry if the thread was repeated.
Attachments below shows the batter drained

This is the battery reduction graph during safe mode tests

There must be a rouge app running somewhere.
Your phone doesn't seem to be "sleeping" at all.
It's whatever is causing the extremely high (100%) awake time, that is causing your battery to drain so quick.
Would be helpful if you could send a screenshot of the main stats page on gsam. Example below: (from my M9)

How Bad is Your WiFi Standby Drain?

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.
