Are you having high battery drain with XXJVK firmware, or any other 2.2.1 firmware?
Does your Battery Use shows high CPU usage time on Android OS?
Then, check if you ever had Software Updates logged in! I noticed high battery usage once I logged in for OTA updates. Possibly, the device is retrying the connection to update server (which will always return timeout). You can see the Software Update service running all the time once you logged in.
If you have logged in Software Updates, go Settings->Applications->Manage Application->All->Software Update->Clear Data
Once you have logged out from Software Updates, the service disappears and personally, battery life doubled.
Thanks, i will try it!
It really could be the last chance to solve my idle-drain-prob.
i'll report back.
//edit: cleared data, service automatically stopped. i'll report back tomorrow if it solves my drain-thing.
Yup i had it running too since boot.. cleared data and will report back
Let's hope this is the answer. I've just took the drastic measure of doing a hard reset and now battery drain is pretty much zero and phone is idle when screen is off. I'll keep installing and enabling things and see what takes more battery.
Very interesting, I did check if there were any updates, and I suffered from random battery drain. At first I suspected Google Maps/Navigation, but you could be right. I started Maps, and Navigation, killed en cleared OTA, and I am monitoring the battery.
I have found that when i use the built in task manager to "clear memory" as soon as i have done that the battery drains alot faster and my android OS in battery stats goes through the roof (from 5% to something like 14%). It has been running fine since yesterday and i cleared memory only to find my battery went very quickly from 28% to 9%. I rebooted the device and all is well, i wont be using that option anymore
After installing jvk full I installed jve modem, rooted and did battery stats wipe and battery issues went away.
i lost 25% over night in airplane mode
background & sync = off.
after clearing dalvik cache & battery recalibration using battery calibrator from market i have 5-7% drain per night, and 30-40% per day... last battery time was 2d 19h 14m, with some calls, some games, some wi-fi and some hsdpa & with weather widget update every hour.
info
i9000 + JVK (repartition 512, with bootloader) + CF Root
P.S before clearing dalvik cache & battery recalibration with same use i have maximum battery life - 23h
Clear the data for "Samsung Account".

There's something very wrong with your phone, either your battery's shot or there's a rogue program draining it, you shouldn't lose more than 1-2% overnight in airplane mode.
Same problem here. I hate this device...
Is it just me that think battery life is much better than on froyo?

I have no battery drain since i upgraded to jvk.

I'm seeing huge battery drain like others, sometimes more that 50% in a few hours doing absolutely nothing, wifi & 3G off and OS takes up to 60% of the battery usage. I never activated Automatice Updates since I flashed JVK. I am now on Darky's v10RC3. Only a few people are having such problems, most users say they are experiencing their best battery life ever.
I noticed that this drain always happened to me after I used Maps / Navigation. So I suspect them to create problems, maybe kicking off Software Update in a bad way. And rebooting stops the drain (it once took as long as a full flash for my phone to reboot...?).
So I have bought for $1 this nice app called Autostarts that shows which apps autostart, what triggers them to start and it is then possible to disable by app / event.
When I tap on Software Update, I can see that it kicks in on these occasions:
- After Startup
- Application installed
- Application removed
- SMS received
- Secret code entered
I disabled everything as well as for Map, so now it's no longer showing in running apps / processes.
Will follow this thread !

Spot on.
My Android OS battery usage is down to 3-5%.
Great find guys, Thanks a lot!
Also, a little suggestion here but I need someone to confirm.
Regarding Google Maps, I was having some trouble getting rid of Hotpot and Rate Places processes as they were constantly running for no reason and restart after I kill them. Another 13% drain. So yesterday I updated to Maps 5.3 and the processes are no longer there even though I've used Maps, Hotpot and Places
I upgraded with odin, repartition and bootloaders. Since now the battery life is very good, i can see the difference by eyes.

today the message is changed form "connection time out" to "no update available" maybe 2.3 is coming?
This worked for me.
Battery was awesome before the update, did the update with 100% battery on the charger, now my battery life is abysmal.....how do i fix it
jump in a circle while chanting.
seriously though, you need to give more info than that. Did you have to flash back to stock before the update? were you modded at all? did you change apps or settings?
if you really did nothing but update, run it to dead, meaning leave it on until it dies, then charge to full. see if that helps reset everything. otherwise check your apps/update scheduals/usage habits.

no flashing back to stock, only thing i had done prior to the update was root, and changing the apn's for tethering. Same backgrounds, usage, etc...i'm noticing probably 50% faster battery drain after the update

well, do what i said, run it to dead, charge to full, see what it does. If that does nothing, check your apps, something may have changed without you realizing it. You can look at settings > battery manager >click the battery icon, see what is using battery. if that still isn't good flash to the stock 4.1.26 SBF and upgrade again (start with full battery)
Hi there, i dont like lollipop battery stats.. It shows only remaining time.. Ad i want know current uptime.. So is there any app or way to make it like kitkat? That it shows how much phone uptime is..
Thanks..
I'm looking for something like that too.

So I switched over from my OP3 to S7 Edge as it was supposed to be an overall upgrade. I used to get through a day of work (7:30am - 5pm) and still have ~40% battery. With the S7E I have to top the phone up before leaving work and keep it on battery saver. I changed the firmware from EE branded to unbranded and I am un rooted.
I was absolutely loving the battery life of my s7 edge until a couple of days ago when it started discharging at a ridiculous rate. I tried getting rid of a bunch of apps that I wasn't using but that had little effect.
Yesterday, I wiped the cache in the stock recovery (I'm also unrooted) and I'm back in business! I doubt I'll ever know what was going on (Android system was using 32%) but wiping cache is an easy fix.
My next step would have been a factory reset which I was planning on doing after Noughet lands officially. I'm happy to put that off as it's a bit more of a PIA for me setting up my watch and other peripherals..

I've wiped the cache in stock recovery and unfortunately it didn't help. As with you, a factory reset would be too much hassle at the moment, so I'm trying to avoid that route. It really is a nightmare to try and solve!
Is this battery life normal? I'm always on 4G with minimal gaming. Please tell. Thanks.

Your Android system us killing your battery, it shouldn't be first in your list, have you disabled all reporting , Samsung,google reporting diagnostic policy stuff, and have you disabled nearby device scanning

Settings/more connection settings/ nearby device scanning turn off
Settings/privacy and safety/report diagnostic info turn off
Those two alone will make a good impact on battery life/Android system drain and also turn off any reporting in Google settings also

You can also turn off wifi network notification in range
And turn off any advanced features you don't use in settings but your screen should be first in your list right now my screen has used 42% of battery and Android system in second using 18% which is acceptable

That's really impressive and makes me jealous! Out of curiosity, what does your % drop over night? I'm sure mines is about 15-20%.

2% drop, I don't use AOD, I have the sd820 btw
If you guys dont care about warranty and stuff. I would recommend going to apc8 firmware of apf2(has some security issues like being outdated and such but if those dont matter to you then apc8 or apf2 is the way to go!). Im on apf2 rooted with prometheus kernel v.1.4 and here are my stats. Light usage like netflix or browsing but the standby is great!
I have 5h 30min screen time
I'll report my screen shots later tonight to see if it's improved. It was at 100% two hours ago and now it's at 80%, so a loss of 10% an hour still seems quite high? I've just checked and Android system is still consuming 23% compared to 9% for the screen. It's frustrating how some people are effected by this and not others.
So my battery has almost died and here are my stats. Any other tips to fix this?

What's connected to your phone during the day and what kind of apps do you use the most? Maybe we can find some more things to disable/find more battery friendly alternatives.

I recently started using a pebble but the problem has persisted since before then. Today I've sent about 10 whatsapp messages and sent about 3 snapchat. I've used the recent apps and used "closed apps" to shut them all. It's as if my phone won't go into doze.
Hi there. I just have a quick question. I've updated to Nougat a week ago, and right after updating to Nougat performed a Factory Reset. Now I've noticed that I'm draining through my battery faster than I usually did in Marshmallow. Now, I've already wiped cache partition and performed another factory reset and wipe partition and my battery is still draining like crazy. I lose battery constantly even though I leave it on standby and I lose 15-25% when I leave it when I sleep and data nor wifi is on. Help would be very much appreciated.
I only use Greenify for battery saving apps.
Android Os is draining my battery in standby too i have tried literally everything like location off location history off all kinds of connections off but Android OS just cant stop draining battery in standby for some reason . I am ON VNS-L21C185B360.
Hi Guys, do you still have this problem? In my case after 2-3 weeks battery stabilized and now it's around 15-20% better than on MM, and I'm not using any battery saving plan
EDIT:
To be specific: on MM I had around 4-4.5H of SOT (a lot of LTE, a bit of Wi-FI, mostly Chrome and YT), now I have at least 5h, sometimes 5,5h SOT
You can use a permission manager.
Edit EVERY APP and uncheck "wake up" , "keep awake" and "start at startup"

SOT isnt the issue. If i keep using the phone constantly i get same SOT as on Marshmallow but the issue is battery drain in standby. Android OS keeps the system awake. There is no rogue app either as Wakelocks are shown to be from Kernel (Androd Os) in every wakelock detector app.

Hi! Thanks for the input. So on yoyr first few weeks you had roughly 4 hours SOT? But how about your standby time? Does the battery drain even on Standby?

Standby time is nuts. On MM I only lose roughly 5% overnight if I leave it. But 25% loss is insane. How's yours?

I used to lose 2-3% on Marshmallow. Nougat Standby drain has always been a problem for me. I had the same issue on b336 and now same on B360. I sometimes lost 10% sometimes even more than that in 7-8 hours overnight. Btw Turn Auto Brightness off before sleep. It will improve standby time a bit.

How long have you been on Nougat? I lose no less than 20% over the course of 8 hours and that's on bare minimum: no automatic brightness, no wifi, no data. Tho GPS is on, I don't think that should be the case because marshmallow held charge on standby like a champ (well, at least in comparison to Nougat).

Hi, I'd just like to up this thread. Any tips? Unfortunately I've already done a factory reset to no avail. Battery still eats 20% in 5 hours idle. Android OS still eats 30% of the consumption.
