Poor battery life after P6800XXLQ2 Flash.

I flashed P6800XXLQ2 everything is butter smooth and rock solid stable, but... it chews battery like crazy when it idles.
I had 30% batt, locked it and went to sleep. This morning I found it dead. If you look at the battery curve it always goes down at almost the same slope, does not matter you use it, or not.
EDIT
I tried wiping battery stats and disabling WiFi wile locked. Still the same.

I follow below suggestion and it seems to work.

I had the same issue having my WiFi off. I had to turn it On and then Tablet started working for days just as before
Turn on - for longer battery life, weird, but that works

So which of these I should chose?
Keep Wi-Fi on during sleep if you turn this off it’ll help extend your battery’s life when the device is put into sleep mode.

Always.

OH WOW! Last night I disabled WIFI & Mobile data and locked my device. It had 59% battery. Now it's 58%!!! After 10 hours. There are some serious problems with LQ2 power management.
It aways goes down this straight slope. Does not matter if I use my tab at all. But last night?
So phase 2 of my test, I will use WIFI only, and no mobile data.

some times this happened to me also ... and then I noticed because some application still active in the background eg game and youtube internet browser. even after I quit .
I did experience also my galaxy tab 7.7 was warm /hot ... this was because the game and internet browser still active in the background.
So after that I always "closed all applications" from "task manager" ... no more battery issue or warm /hot issue again.

OK I have disabled mobile data entire day and set to disable wifi when locked. My tab was almost unused all day and this happened.
IT IS WIFI RELATED!

Onto my 3rd factory reset due to battery drain!

Hello folks,
I've had the Rogers Galaxy S 5 for about a week now, and since day 1 I have noticed excessive battery drain by "Android System". This source of drainage occurs especially during idle periods of time causing me to experience rather poor battery performance.
This here is a sample of what my battery stats look like at any given time, notice "Android System" is virtually always the number 1 source of battery consumption.

}
I executed a factory reset on the second day of ownership to examine whether this drain would be solved. It wasn't.
I went to bed, and woke up in the morning to check Gsam Battery monitor which gave me this chart:
Notice the part I highlighted in red which demonstrates the overnight battery usage!
Also, GSAM battery monitor still displays "Android System" as the source of the drain.
Among my colleagues I am the only one experiencing this phenomenon, and I am going to factory reset for the third time right now.
Going to run the stock firmware to see whether I am still experiencing this.
I will report back with any new findings soon, hold on tight to your seats!

I suggest you do the following,
-Disable Location in the notification drop down
-Turn off Hot Word detection for Google Voice Commands.
-Disable bloatware
-Turn off always active WiFi in advanced WiFi settings.

AND,
Try giving it a week to 'settle' without resetting it...
It needs to figure itself out...
All my family member noticed significantly better battery AFTER 1st week.

Certainly performed all of the above right after factory reset! Battery still dropped over 10% overnight on standby.

S4 high battery consumption

hi guys,

the day before i tried this with the network on nfc on, data and wifi off and the consumption was about the same.
i have yet to try flight mode on and nfc off, but i wouldn't think that nfc would use that much.
i use greenify to put a lot of apps to hibernate so they wont wake the phone.
starting to think my battery isnt performing right anymore.

17% in 6.5hrs, airplane mode, no nfc.
the phone is definitely going to sleep.
i could leave the network on and nfc too, difference isnt big at all.
any idea is appreciated. leaning towards bad battery here..

Why not remove all the extra apps, and see if anything changes. Then, you can install one by one when things are clearer.

i would believe if an app cause the drain with the screen off then it is probably causing a wake lock.
which doesnt show at all. is there any otherway an app can drain the battery without wakelock?

I don't really see drain? 2% an hour is not that much. In my opinion it's normal.
If you insist on lowering it, then try the following:
- Different rom
- Different modem
- New battery
And search for some guides to lower your battery usage.
You have to experiment yourself.

it didnt use that much before. in 15 hrs i got a bit over an hour screen time before it hit 0.
anyway, just loaded romswitcher, going to see if it happens with CM too. and airplane mode on.
starting to think the battery is going bad already

I average about 0.5% drain during sleep.
See the link in my signature to find out how. I've got a whole guide.

Have you checked the serial number on your battery? If it starts with BD then it's stuffed Samsung should still swap it for free I think.

thanks for all the replies guys.
yes 0.5 drain should be normal when it sleeps.
just tried this using CM rom and it looks all good there, so its not the battery.
going to remove some experimental settings in greenify to see if that helps.

How do I figure out what's causing my wifi to stay on the entire time?

In recent memory I've noticed that I'm losing a significant chunk of battery even with the screen off.
Looking at this screenshot from GSAM battery monitor, I've barely been using my phone while it sits on my desk but the battery has dropped 25% with the wifi looking like it's been active the entire time.
How should I go about figuring out which offending app is causing this?

Turn off keep WiFi on during sleep in advanced WiFi menu.

Go into Settings/Location, hit the menu button and select Scanning, then turn off WiFi scanning.

It's no longer in that location, see above.

wifi scanning has been turned off in location and it's still the same result.

OP, I have the same problem and it eats the battery. It happens everytime I take my phone off charger, turn wifi on, browse some Internet, turn the wifi off. WIFI stays on according to battery stats. The only thing that helps is to slide the wifi toggle on in setting and then off and reboot.

WiFi weirdness and (possible) cause of battery drain?

I've noticed some WiFi weirdness since I got my (vzw) 10. While watching a video in chrome, sometimes (usually right after a reboot) it'll play perfectly fine. Other occasions it'll have issues streaming, and when it pauses to buffer, it takes way longer than it should. Most of the time it completely freezes up chrome. Disconnecting from WiFi so it uses the data connection and it immediately resumes playing and has zero issues. Even occasionally while browsing the web, it'll just completely fail to load a page.
On a side note, I won't be able to confirm till tonight when I sleep and I leave it on disconnected from WiFi, but it seems to drain the battery. Obviously WiFi drains battery, but I'm talking crazy drain, 10-12% over 7 hrs.
Can anyone corroborate this happening to them? I'm thinking possibly firmware or ROM bug.

I have the wifi on during sleep only when plugged in and wifi stayed on all night, its a solid bar. I've barely used my phone since waking up and its already dropped 9%. I am seeing a drain issue and I can't find it.

So it seems like we have WiFi issues then. I'm curious, do you have a vzw 10 or no? Wondering if it's a vzw only issue.

Yeah VZW 10. I don't know if it is actually the wifi, but I had to charge 3 times yesterday. Everything drains the battery.

yeah lost 15% in a 6 hour night. wifi always on.

I'm not even sure myself but my battery drains at a rate of 1% every 10 minutes even on standby. I've disable auto-sync, and it helped slightly but it's still draining abnormally fast.

You guys with issues on drain are you on 5ghz radio or 2.4ghz.?

I've tried both, there doesn't seem to be a difference.

I'm on AT&T network. I lost 1% overnight over a 7+ hour period. I was quite impressed.

AU unlocked set, lost 10% throughout the night with WIFI on.

Anyone who has root (obviously not vzw yet) wanna do some testing and find what the drain cause is?

I still haven't been able to nail down a fix for WiFi being unusable sadly.

I have the same issue when it comes to battery drain on wifi. You guys could try and disable the following settings

This helped for me on the international HTC 10
