I know battery has been diacussed before but i think this isnt normal. I left the office with almost full charge, listened to music on the.way with bluetoith headset for an hour. Got home and browsed for like half an hour. And here is my battery.
3 hours and the phone is almost dead. I have no apps running. I had 3g on when i left the officw and at home i used wifi.
Is this normal or should i take the.phone back for an exchange?
Regardless, i still love the phone.

RETURN ZE PHONE
get a new shiny in exchange
btw when u return the phone what do u say exactly
Thats ridiculous man. Maybe you're battery is broken.
That said mine has just drained 35% in 3 hours with almost no usage so maybe it is just the phone.
I think there is 100% guaranteed a software problem and we need samsung to fix it.
It says you've had the display on for quite a long time, music needs the display on? Also that wifi sharing is another culprit.
It drained because you had the screen on nearly the entire time not because anything else
Unless thats a case of the 'phone staying awake' bug. You can freeze wifi sharing with titanium backup to save some juice

I too am facing the same issue battery drain from 100% to 60% in a span of 3 hours.
I am having a mediocre usage of battery with touchdown as my mail client talking to my corporate exchange. Still it doesn't warrant a drain of 40% in 3 hours.
I dont have much apps installed. Even with juice defender I am not getting better results.

You could say it's normal because if you haven't yet rooted and frozen the wifi sharing process this is the exact behavior everybody else is also having. A new phone will behave in exactly the same way if it's using the current firmware.
You can do two things.
1. root and freeze the process with titanium backup or similar.
2. wait for the next official samsung firmware which may include a fix.
The rooting process takes about 15 minutes and is not too difficult. You may or may not get in to warranty trouble in case of repair, but as I and several of my friends saw it, there really is no other way unless you want a phone with 3-4 hours of battery compared to the 19-23 hours we all get now after the freeze.
Another thing, it won't matter if wifi is turned on or off, the bug and wifi sharing process will still be there.
You will probably read around the net that several processes has to be frozen, but it really only is the "wifi sharing" one that needs to be frozen for the battery drain issue to go away.
What is the "wifi-sharing"?
Mine GS2 is a bit different from the OP's. Android OS occupied 45% while Display only 19%. And charging time is unusually long. Very long. I plugged my GS2 into PC at 9am with 30% left, and by the time I left work 6pm it only got up to 75% something. That's half a day charge.

Sorry, whats the freeze. I haven't heard this before ?
Thanks

I don't really know. But I haven't found a feature not working after the freeze. Even dlna sharing, hotspot etc.. Everything seems to be fine.
You can read more about the issue here:

Regarding the unusual long charge time, I haven't heard about that before. It takes my phone about 3 hours to fully charge.
I can recommend this application for monitoring if the phone really sleeps when left on the table and which processes uses your juice in general. It's history based and you will be able to figure out a lot of useful stuff with it.

I'm also have a similar problem, but mine was after one hour and an half of web surfing using dolphin HD and wifi... it was full, it's now about 25% remaining... Is it normal that the dolphin browser used 39% of the battery ? It's even more than the display... !
Ps: it's actually really hot on the back of the phone, on the top, just under camera... Normal ? ? ?

Well. When you have rooted your phone, you are able to do a lot of usefull stuff:
-Freeze processes
-Disable the camera shutter sound with a simple property/text file
-Make the middle home screen the real home (like htc sense) with a simple property/text file,
-Replace camera.apk and get higher quality sound in video, actually also higher video bitrate if you want that.
-Replace talk.apk and enable the upcoming google talk with video chat
-Install chainfire3d driver to be able to play tegra2 gpu based games
...and probably a lot more, but above is the only things I've done.
Freezing means : that you lock a process you don't want to run ever. You are also able to "un-freeze" if you decide to revert.
So:
1. you root your phone
2. you install titanium backup or other application that has the "freezing" ability.
3. open the freezing app, go to the process list, find "wifi sharing", press freeze, reboot
Problem solved, "wifi-sharing" will never run again.
You want to revert: Launch titanium, go to process list, find wifi sharing, unfreeze, reboot. Everything back to where you were before.

I really don't think anything matters as I can see you have the wifi-sharing bug.
You must understand, that it's everybody with the current firmware that has this bug. You must either wait or root and freeze.
Sucking up your battery in a couple of hours and making the cpu run at full speed which makes the phone get hot is exactly what this wifi-sharing bug does.
There is absolutely no way you can change anything in the settings or say, not run dolphin browser to fix this problem. You simply have to freeze the process or wait for samsung to fix it. As long as the wifi-sharing process enters your battery usage list you have the firmware that has the problem (and it's more than one) and your doomed until you freeze or upgrade to a future firmware where the bug may be officially fixed.
Just another "wifi-sharing" discussion link:
https://code.google.com/p/android/issues/detail?id=16721
Alright then, it's just that it doesn't seem me to be that much of the battery (~20%...)
I did just freeze that process and will see once my phone is fully charged... Thanks.
Try the lite'ning rom. It is much better!

isnt this pretty normal looking battery drain? most people on this forum are getting about 4 hours screen-on time, sometimes 4.5 hours. yours seems to have the screen on about 4 hours from your graph picture. isnt this normal? if it was all gaming usage it definitely would be normal...
@OP, You mind to mention the Screen On time please?

oh, was that a constructive comment?
I'm using the Neutrino ROM right now. My phone will get very hot after a while, usually during browsing and the battery will drain extremely quick. It use to not do this. I thought it might be Dolphin HD browser I was using but it does the same with Opera mini.
Any ideas on what I can do to fix this? It never did this before and I'm only half way through my day and it's already at 40%. I use to be able to get through my entire work day and still be in the good 60-70%...
I had this same issue when I first got my Atrix and it started happening after I rooted it and customized it. Even after a factory reset, it still ran hot and the battery drained quickly.
I ended up performing a complete factory reset and took the phone back to get it replaced. The replacement worked just fine, even after rooting it and doing the same customizations I had done with the first one.
If you just got it, I would suggest taking it back and getting it replaced with another one. It could just be a bad battery.
My 2 cents!
Here are a few things to help you diagnose your battery drain issue.
Download "CPU Spy" from the market. This program will show you how long your cpu has spent in each of it's various clock states. This program does not reset it's data until you reset it, and your phone's cpu will not sleep while charging. So charge the phone then open the program and reset timers. Now wait a while and check the stats. Your cpu should be going into "Deep sleep" mode most of the time you are not using it. If it is not 75% or more deep sleep after a couple hours, or if it shows deep sleep under unused clock states then you have some condition (probably an app) keeping it awake.
If you have an app keeping your phone awake you need to determine which one is doing it. This can be done by backing them all up with titanium and deleting a few then testing (takes forever,) or by way of another program. I use a program called "better battery stats" from the market, which is a paid app. This app gives you information on wakelocks, partial wakelocks, and processes that are running. It can be used to find the process responsible, which you then trace back to the app that is using it.
I found out about all this when K9 mail was running away with me. It wasn't too bad as long as I was connected to wifi, but while traveling it would constantly use a very small amount of data and refuse to let the cpu sleep. I deleted it and for about 2 months now I get home after 12 hours with 60-70% or more battery life and about an hour of screen time used. My deep sleep percentage is in the 80's every day. My phone is runnign Jokers's cm9 overclocked to 1.45.
Hope this helps.
Try badass battery off market, it will let you see where it drains
Just switched from Nutrino... What version are you using? EE/GT/GT+? I only used the EE because its stock clock speed. I noticed CPU gets extremely hot with slightest OC. Also, noticed quick battery drain while screen was on (quicker than other ROM's)...

Also, if your using the gt+ version with the over clock kernel like I am using, do the phone a favor by keeping the phone underclocked at 1000 MHz instead of 1450 MHz. That will help the heating up too. That's what I do. Battery is great too.
Sent from my Atrix with XDA Premium
As Voelker does, I have the 1.3 version of Neutrino but keep it clocked at 1Ghz max with SetCPU profiles most since any overclock tends to get warmer than I want. I havent had a temp crash yet, it's just me being paranoid sometimes. I do set it to 1.3 when I am playing games for smoothness, but I havent noticed any unusual battery drain, just more heat than I want.

This mod promise to almost eliminated the lag on any android by providing more random number for vm use (you may not aware but when process running, it require a lot random number for various task, when it run out, lag happen - that's the theory).
Just saw this on xda front page and tried myself Fly + JJ3.3 with a lot of modded by myself.
It still too soon for me to confirm it work or not, but so far the phone is not sluggish at all (last 30 minute, playing with heavy browsing and map and instagram to eat all the memory).
I use seeder_v6 script http://forum.xda-developers.com/show...&postcount=738
You can try with the apk (second attachment in #1 post first to see if still skeptical about this stuff)
Please share the experience in performance, battery, abnormal behavior of phone if happen.
This maybe a biggest performance tweak for a long time.
Sounds interesting. I'm curious if it really works and how does it affect the battery life. Please, can somebody test it (or already done it) and can tell something about?

I currently using it. Most noticeable is how quick recent apps list popup. Many apps startup quicker (look like they use a lot of random data at startup) - but when you already run low on ram like heavy browsing, this will not able to help you reduce the lag.
I'm currently on happy side with more snappy recent apps list, it kinda too slow for me before. But maybe it's because I've just restart the phone, need hours before I can really judge it. So much placebo for now.
This zip is to flashing via recovery, yup? And how to uninstall this?
Yes, via recovery, I'm uninstall things by checking what in the zip and what already in system, so I can revert it.
You sould try the apk in the first post of that thread first, if it work well, dont need to flash anything.
Actualy.This brakes the system. I have tasted it. Many games become fc also. It boosts the benchmark score but... It is just not for our phones. Feel free to try it but..
after install zip free RAM chages from 250 to 270 on 2.3.4.
I'm using REPACK4PDA with special settings.

I am using it, and it is pretty good at eliminating lags for certain functions, but it wouldn't surprise me if it screwed up some other things, like Mr Tapa pointed out, so like most android things it is probably up to the end user to decide if it is worth it for them or not.
So far only smart app protector FC on me, but this app also update yesterday so I dont know if seeder really the reason.
In theory, just pump more random data into the pool can not break the system, the problem maybe it not random enough or something.
The result is very positive for me until now.

Maybe it awake more, but clearly not at a rate I can see difference visible on that graph.
If someone already have BetterBatteryStats installed can do the test with clear number.
No noticeable for me until now about battery life decrease,
Even if it's noticable, I willing to give up 10% battery for speed, it last about 42h average previously.
The reason for more free ram and more snappy apps startup is not clear. Actually it's hard to believe this flaw not be addressed for that much long.
But for what ever reason, snappier phone is still a snappier phone, and I like it. Maybe they should try to study what the real culprit in performance boost and give it to me...

hhhmmm, what you say makes perfect sense, but that is not what is happening according to my phone. I have checked and checked to make sure that seeder is working using the terminal commands but it I am not seeing frequent wake ups on the battery graph, and it seems like deep sleep is OK.

gsam with root companion is pretty popular.
I had problems using with the original 75 degree thermal mod. I had to go back to stock thermal to fix my problems.
I used this for wakelock detection:

I use BetterBatteryStats to monitor what processes are waking up the phone. And I use Greenify and Amplify (Xposed module) to control wake locks. Can't do much about screen on time, but these significantly increased (went from 2 to 3 days for regular usage) my battery life when I'm not actively using the phone.
Just bought a Samsung S6 Edge, my first venture into samsung devices since before I purchased my first HTC the G1. I have always been an HTC fan but I thought this phone look pretty special and so I took the plunge.
Since then however I have been nothing but disappointed. When I first started to use the phone it was very responsive and the screen and features are very impressive, however my HTC M8 is at the moment considerably faster with Lollipop 5.02 and M9 ported software than my S6 Edge despite having considerably more power. When I open the smart case the screen only turns on for 1 second then turns itself off, the phone is laggy and it can take some apps several seconds to launch. Side by side with my M8 it just isn't coming close using the same setup and the same apps.
After having brushed of the fiasco over the charger of my Samsung Gear Live watch breaking the rear of the watch I am not sure I trust Samsung?
What is wrong with this device??
I came from the HTC One M8 and s6 Edge is faster.
Maybe you got a defective device?
I have no lag at all on mine and I haven't heard anyone complain about lag so far.
Its not laggy, you're laggy!
Mine has been lagging considerably and overheating quite a bit. It's very frustrating. Also, the battery is terrible.

Your issues point to a rouge app. It sounds like the app is sucking CPU time constantly and thus your phone is overheating. This also causes big time lag and battery drain. Get an app like GSAM or Better Battery to see which app is causing the issue and then kill the app!!

Download Better Battery Stats and see what your leading kernel wake lock is. Mine was something no one had heard of and Google had NO info about. It kept my phone awake 60% of the time or more - no amount of flashing stock firmware or factory resetting helped. I had to exchange the device. The wakelock in my case was lli_pm_wlock

Oh wow. I've got the exact same issue. So this is something that can only be remedied by replacement?
Your chart looks crazy. They're ALL at 100%. I'd return it if flashing stock firmware didnt fix it.
Use smart switch to back up your apps and data, then use it to reinstall the firmware. Restore your apps/data and see if you're fixed. You'll be all stock again but its worth a shot before doing the return.
Maybe it's caused by memory link.
I believe all this lagging issue is caused by memory link. My Ram is always on 87% (2.2 GB of Ram) yet i'm not running any app, sometimes i tap and it doesn't respond, then after a couple seconds it responds to all the taps made which drives it nuts. Otherwise, i love it, it's very fast and smooth most of the time. Been a fun of HTC for years, S6 Edge is my first Samsung Phone and i don't regret changing. Hope they fix the few problems some of us got.
