So I have been having some battery life issues like some users not being able to get a full day. But there has been a few times I have had my battery at %50 and then after a reboot it starts up and says plug in charger your battery is dead. Today I had 90% only been using for a few hours. All I did today was remove handcent and put on go sms. I also installed juice defender but I have it just on default settings. Go sms was stuck in a search so I rebooted my phone. I had 90% battery and when i started back up it says my battery needs to be charged. I have done the whole charge / whipe battery thing before didnt seem to help.
Oh and i'm running dk28 mightnight rom.
sounds like a bad battery. Most sprint stores with service centers have a cadex machine that they can test your battery with.
I have been seeing the exact same thing. I will reboot the phone with what appears to be a lot of battery life left and when it comes back I'll get told I'm at something like 10% and I should connect the charger. Luckily I have two batteries and I keep the second one with me in the pocket case/charger.

Same issue here with drastic change in charge level after flashing a ROM or even just flashing a new app or UI change via CWM when using my cheap ass Chinese eBay batteries. I've yet to be able to recreate the problem while using my stock battery - and I've tried. If you are using the stock battery, it's probably going bad. If you're using a cheap eBay battery, well, you get what you pay for I guess.

Both of my batteries are stock and I don't think it's a bad battery. I can go several days with great battery life from both batteries and then out of the blue I'll restart the phone for whatever reason and POW! Come to think of it the only reason why I usually restart the phone is to either swap batteries or because performance has dropped dramatically. Now I am wondering if there is a run away process that is chewing up the battery but the usage isn't being reported until after the reboot.

My battery is stock also. And mine appears to be random also sometimes I will have mild to high battery drain and other times its BAM %50 to 0 on a reboot or something it doesn't really match up with use or anything. I do have a Chinese battery on the way. I'm draining the battery down a bit more now and going to do another full charge with it off and then wipe the stats. Hopefully it helps will also try to stop at the sprint store and have them test the battery.

This was most prevalent for me when running EXT4 using the ext4 compatible bonsai roms (and the other ROMs that use bonsai as a base)
i've gone back to RFS and the 1.0.4 (I think) bonsai ROM and the problem has gone away.
my phone would be fine for quite a while, then i'd notice crappy performance, browsing, texts not being sent/received so i'd reboot the phone and come back after boot and the battery would be almost dead.

I am on ext4 also. I have been thinking of going to another rom and possibly off ext4 but I was trying to wait for final froyo custom roms..ya I know stupid me lol
I'm ruining running "stock" DK28 so I don't think it is an EXT4 issue as much as maybe an issue with DK28.

Looks like it goes away
I am currently on Bonsai v2.0.0 rom with Gingerbread Theme.
My battery performed weird when I just flashed to Bonsai rom. After reboot, the battery suddenly dropped from 50% to 15% and told me to charge. However I believe it happened due to flashing a new rom and battery not calibrated.
However, after a week of normal using, the battery seemed to have been calibrated itself. Now it performs okay. I have been lightly used (facebook, XDA, Engadget, weather checking on Wifi) with screen brightness set to auto. I also played music on phone speaker for about 20 minutes while I am cooking. Oh, I didn't get a call, so no call usage. But I did some email checking.
I had Advanced Task Killer set up to auto kill processes every one hour. I killed facebook when not in use, as I heard that facebook chat causes major battery drainage. And I also set mostly black wallpaper in hope to save some battery. I heard that saves battery a lot for some reason.
Anyways I have attached the screenshot, although I didn't use much, I believe that I can withstand a day with no problem.

Not to change the subject but you brought up Swype. Is it just me or has anyone else noticed that the more they use Swype the worse it seems to get? I loved it at first but now it seems like it's been hitting the crack pipe.
With due respect I think you're all wrong. I've had the same issues... sometimes at random after a restart
Shut down
Pull the battery
Put it back in
You should see your normal battery life
It's actually reading way lower than the battery actually is

Swype remembers mistakes that we make when hitting each key.. once a week or once every couple weeks I'll go to menu > settings > spplications > manage > select all apps > swype > force stop then clear cache.
that always gets it sober again.

The thing is, it shouldn't be happening. I can say for certain that after removing EXT4 and flashing back to the last stable (for me) Bonsai ROM I have not encountered this anomaly even one time (been 2 wks so far)... call it a coincidence, call it a solution. You decide.
Just sayin'

Clear cache or clear data? In Cache it shows 0.00B but in Data it shows 396KB. EDIT: I took the plunge and cleared data. That was it.

I tried this and no luck. I restarted the phone with about 80% and when it came up I got the critically low attach charger message. I then powered down, removed the battery, let it set for a minute, put the battery back in and booted. Still the same message. I'm keeping better track of usage and such today to see if there is something I can contribute this to.

In my experience, there wasn't a 'guilty' usage pattern or app that caused this for me.. I noticed that when the battery gauge showed around 60-70% my phone would start performing very poorly.. I'd reboot and when it booted, came back w/ critical low battery.
As I posted before, I reverted back to RFS and haven't had this issue yet.
Glad to see I'm not the only one having this annoying problem. I hate having a full battery and after 2 reboots I have a low battery. Its hard to believe that a reboot takes so much power.

3rd party launcher
So I was having a problem over the last few days trying to see what was eating up my memory and battery.
This was my solution to my battery drain:
If you have a 3rd party launcher, like LauncherPro, go turn on TouchWiz (via settings->applications->manage applications->3rd party launcher->clear defaults). Open up both TouchWiz and the Default Android launcher one at a time, and make sure you delete all of the widgets and anything that might be operating under the other launchers.
LauncherPro and ADW do not turn off TouchWiz, they are really just an overlay. So if you have, for instance, the Sprint TV widget on a home screen through TW, then it is still operating while you use LP or ADW. I use this example because it is a widget that Sprint has set up to automatically be placed on the home screen when you buy the phone.
Also, I would recommend looking at these three apps that might show you what is draining your battery: OS Monitor, Android Assistant, and/or Battery Doctor.
Hope this help you in some fashion to uncover whatever it is that draining your battery. If nothing here helps, I would do one of the battery calibration techniques here
HI guys i will be showing you how i recalibrated my battery and it worked for me,
1.charge phone till full (EVEN IF IT DROPS TO 98 AS SOON AS YOU UNPLUG ITS OK)
2.drain the phone and i mean DRAIN turn on everything (sync,wifi,bluetooth,everything
3.once your phone automatically switches off try boot if not boot into download mode
4.stay in download mode until it switches off again
5.once it switches off try accessing it again keep on doing it untill you cant
6.charge phone till full (make sure you dont switch on phone)
7.once it says full take off phone charger and quickly put it back in make sure you do it fast and do this 5-6 times
8.without taking charger off boot into recovery
9.wipe battery status but as soon as you are about to wipe quickly take off charger once it wiped put it back in and reboot phone
10. give it 3-4 days and make sure you do battery cycles
11.try flashing a different modem im using ZSJPG link:http://insanity.rollus.net/addons/modems/ZSJPG-Modem.zip thanks to nitr8 and alll the other rom developers
thx m8 very well explained, ill try to do it later

Have you checked the battery's voltage while doing this? Or is there a built in deep discharge protection even in download mode?
your phone will have a bit of power left to go to download mode for safety incase you do brick it but you cant brick your phone when your recalibrating
Personally i would only go that extreme route if you have a battery problem .
Multiple full drains and multiple bump charges is no good for battery life .
jje
I agree. I wouldn't go that extreme. if u r experiencing battery problem, use battery recalibrate app for galaxy s. (search xda forum and you will find it less than a minute)
It is more than sufficient to solve common problems

It's not so much a question of bricking the phone, it's more if you let a li-po battery (like the one in the SGS) go below a certain voltage it can damage the cells and drastically reduce the life of the battery
Ive read that such discharging your device (whether phone or pda) is not good for the battey, and that you should never try to force discharge it ...
Sent from my GT-I9000 using XDA App
Both bump charging and complete discharging can damage the battery.
Teaching this is both incorrect, irresponsible and dangerous as excessive discharges can under certain circumstances cause the battery to effectively explode the next time it is charged.
http://batteryuniversity.com/learn/article/battery_calibration
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
All this voodoo and mystery around calibration is silly. It's a simple process that need not be made any more complicated. Bump charging may be alright, however it significantly reduces the service life of the battery and so should not be done regularly, without proper warning.
I thought I would add my 2 cents to the battery thread. I am in the UK and have an XEU phone. I have gone through all different firmwares, modems etc. and all of them had one thing in common.....
Anything above XXJPY would just rape my battery and I mean about 50% in about 12h running barebones. Beleve me when I say that I tried all sorts. Currently I am running my own custome deodexed and stripped JPY, and havn't looked back.
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )
That's all folks! Please report your success / lack of such here. Also, feel free to ask questions, and I along with other users with answer them according to our ability.
I will later add a section on "good practices for battery usage" with tips and tricks.
Cheers!
Attached are screenshots of my results after calibration: This was under moderate usage. Pretty damn good if you ask me.
Post-calibration methods of improving Battery Life
Updated: Post#2 will explain how to solve battery drainage problems when recalibration wasn't enough. It will also explain how battery reporting works, common practices, tips, tricks, etc.
Battery Tips / Tricks / Common Practices
Important things to know:
1. It's important to understand how battery indicator on Android works and how Android manages / reports your battery life. Please read this article:
Your Smartphone’s Battery Gauge is Lying to You (and it’s not such a bad thing)
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
2. Li-ion batteries used in modern smartphones don't have "charge memory". Partial charges won't hurt the battery (e.g. charging from 60% to 80% or from 10% to 50% etc). Feel free to give your phone small charges whenever you have time and need the phone to last longer.
3. Smartphone batteries don't like to be completely discharged or to be kept at 100% capacity for extended periods of time (this actually damages batteries over time). But worry not, the battery software prevents this from happening for you. That's why some of your phones never get to 100% or drop from 100% to 90% minutes after you disconnct the phone from a charger.
4. All batteries gradually lose a small percentage of their capacity after a certain amount of charge cycles. It's a natural part of life. It's always nice to have a spare battery or to purchase a replacement when your current battery isn't to the task anymore.
5. Don't pay much attention to the battery %, just use your phones. I know it's very tempting to track your battery usage every 15 minutes and try to find problems. Been there myself. Thing is, if you do this, you might start thinking you have problems, when you don't have any.
Bottom line - just try to use your phone and not mess with the battery unless problems become really apparent.
------------------------------------------------------------------------------
Other proven ways to improve Battery Life
If you have re-calibrated to a full capacity (4200mv) but your battery still drains terribly - follow these steps to pin point the problem.
1. Find which app / process is draining the battery.
If you get lucky, the infringing app will show up directly under the stock "Battery Usage" statistics. However, in most cases "Battery Usage" isn't very informative. Most people report that they only see "Phone Idle" consuming most of the battery without much insight into the details.
Things to do:
- install Watchdog, go to preferences, set CPU threshhold to 20% (or even lower if it's not enough), check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20%(or even lower if it's not enough) as well. Run it for a couple of days.
If you start getting frequent Watchdog notifications about a certain app breaching the threshold - uninstall it, find an alternative.
- install BetterBatteryStats from here -
http://forum.xda-developers.com/showthread.php?t=1179809 run it for a couple of days and monitor apps / processes that are using up more wakelocks than they should.
Once you find the infringing app - uninstall it, if it's a process - find out if it's safe to stop / freeze before doing anything.
2. Freeze bloatware aka "stop the problem before it becomes a problem."
Unless you are running CM7, your rom is based on stock 2.3.4 and still has blur in it. Blur apps and processes might be running without you even using them and sucking out precious batter life while they are at it.
Things to do:
- Get TitaniumBackup, freeze all bloatware that is mentioned as "safe" in this thread -
http://forum.xda-developers.com/showthread.php?t=1182663
Use your phone for a couple of days afterwards and watch for improvements.
If these software tweaks aren't enough, the problem might be with your system setup. Go through these steps which should hopefully fix your setup in favor of awesome battery life:
3. Flash a custom kernel, set up battery saving profiles.
Many people have reported success with this step. Custom kernels are not just for overclocking. A custom kernel with smart profiles will definitely give definitely extend your phones operating life during the day.
Things to do:
- Get a custom kernel., the popular choice on here seems to be faux'es kernel, so I recommend it -
http://forum.xda-developers.com/showthread.php?t=1156040
Get one of the battery saving SetCpu profiles along with it. Basically, a good battery saving profile looks something like this:
- absolute minimum CPU clock with screen off (something like 275 Mhz)
- lowering CPU clock with temperature > 50C (something like ~800Mhz)
- lowering CPU clock when battery < 30% (something like ~800Mhz)
Many people reported success in using such profile for lowering "Phone Idle" drain.
4. Flash a different radio.
WARNING: Be extremely careful with this. Flashing a wrong radio is the right way to hard brick your phone.
Although some people are reporting to have fixed battery drainage by trying out a different radio, I seriously wouldn't recommend going on a flashing spree unless you know what you are doing.
My advice here: flash the latest 2.3.4 for your carrier if you haven't yet. From there on, experiment at your own risk.
5. Disable Data and Wifi when idle either manually or with an app."
I seriously get surprised every time someone says they have a horrible battery life, when they keep an internet connection on at all times. Constant data always = battery drain.
Things to do:
- use apps like Green Power to disable data / wifi for you when you are not using it
- learn to turn off your internet connection manually
6. If all else fails - start over from scratch (read: clean install a rom).
I've heard reports of people getting better life with Froyo than GB, or that a specific custom ROM solved their problem for them. A million dollar question: if it works for you, why not use it?
Things to do:
- try a ROM without blur, like CM7
- try Ninja Speed Freak (developer and many users reported great battery life)
- if battery life is your top concern - try Froyo

Are you using stock Orange 2.3.4 rom?
If yes, your Rom might not have the battery jumping problem. You can still use this guide without the battery fix to recalibrate.
Let's wait for someone with Orange 2.3.4 to confirm if jug6ernaut's CWM battery fix can be used or not.
Indeed, I have not the battery jump issue, but I'm exprimenting some weird behavior...
like when I restart the phone, it shows about 10% higher than before. I tried this multiples times yesterday. When it was about 40%, it starts to drop suddenly, 'till it got to 18% and get back to normal decrease to 4%, 2~3 hours later...
See the images attached, the red circles are the times I rebooted it and the blue arrow is when it drops suddenly...
Question on step 4. To confirm, we shouldn't click on anything in BatteryCalibration, all that needs to be done is take note on the MV number, correct?

Did it only start doing this on 2.3.4 or you haven't checked before? Anyway, I would do the calibration to see if it changes anything.

No clicking in step 4. Just write down or remember the MV number.
Yes it just starts when updating to 2.3.4... In the first days I got the impression of lower battery level, so reading the forums I saw the restart/level change problem, and tested it

You probably updated to 2.3.4 while not at 100% battery level, and it messed up your battery stat. So, yes, do all the steps in this guide except for jug6ernaut's battery fix part.
thanks, ill give this a shot....again.....tonight and hopefully it will fix my issue.

I'm on a rooted stock GB and I'm having the problem where the battery usage stats are inaccurate and won't got below 90% after using it all day. This all started after I used Battery Calibration. Do you think that this would help correct the problem?
Edit: Also, would I need to complete all of the steps including the CWM part? I haven't flashed any roms yet, so I don't know if this would be necessary.

Seems like you used Battery Calibration while not at 100% charge and your battery stats got messed up.
The reason I recommend using CWM is because the battery stats file is created on each boot. So, with my instructions you can charge the phone to 100% while it's off and wipe the messed up stats before it boots.
You can try using my instructions, without the CWM part, except you need to wipe your battery stats with Battery Calibration app after step 4.
lol i left pandora on since this morning and its only at 67%. ugh, when i wanna force drain the battery it goes slow as hell but when i wanna conserve battery live for usage it drains quick. hahaha.
I just flashed navalynt's πCrust rom fully charged, cleared stats through cwm, booted and now i'm close to 3days.

lol yes. I used video playback to drain mine. But if it's really a PITA, you can always just leave it till tomorrow to discharge naturally.

Yep, that's why flashing only when at 100% charge always pays off.
I get the same results by booting to CWM, wiping battery stats, rebooting, starting Battery Calibration, plugging phone into wall charger, charging to 100% (4197mv for me), and then calibrating with Battery Calibration. I start this process at any battery percentage, and have been doing this for a long time now. I have never had to deplete my battery until my phone shuts off, and get great battery life.

After the calibration I had 4200mv, so it seems like you are doing things right in regards to the battery.
"Taking the battery out and putting it back in" trick works wonders though in restoring battery life to maximum state (if you had it decrease for some reason). I've tested it multiple times even back when I had the Milestone.
I can reproduce this bug every time on my phone (Mostly Stock Rebuild + Shadow Kernel 1.0.2). If I'm plugged in and I go to Settings -- About Phone and click Battery Usage I get a Settings app freeze and force close. Can anyone else reproduce it? Does this mean anything might be seriously wrong with this phone or just a quirk?
Mine works fine. To eliminate software quirk you should Odin back to EC05 and see if it FCs or not. Then if it is OK root and flash ROM from there. Try it and if OK then flash kernel and try it.

I should add that it works when fully charged and plugged in, just not while charging.
ETA: oddly enough the phone is charging right now and no such error this time when tapping the Battery use option. Weird. Maybe something that was temporarily interfering...?
Hope someone can help me solve this issue.
The Setup
I recently went out of the country and before I left I unlocked my GS4 following from wonderhowto[dot]com
Arrived to my Carribean destination, bought a prepaid SIM, popped her in and everything worked great.
Problems started when I flew back into Miami. I removed my prepaid SIM and installed my old one, changed my APN name back
and rebooted the phone. Decided to plug it into my laptop (USB3.0) to get some extra juice before the next flight and I noticed that
the battery was actually going down and quite quickly too, about 1% every 3 minutes. The phone was also doing a lot of connecting and disconnecting from the laptop even though it was not being moved.
I use two batteries which I have an external charger for , so this didn't slow me down too much.
After a few days, I thought maybe by unlocking the phone I had left it in some "roaming" state where it was eating up battery looking for its signal, so I decided that I'd restore it to the nandroid backup ROM Manager created before I did the unlock procedure. OH NUGGETS!
Things got ugly , quick!. In the process of trying to restore got MD5 mismatch error, so I went back to 3 previous backups before all of which said either "MD5 mismatch" or unable to open .zip -None of them worked.
Thankfully I had saved a copy of the backup folder in clockworkmod to my PC and tried to load that, it started and then get to writing /data and said error writing data.
I rebooted. Bootloop.
After a few hours of attempts with KIES, and some well timed cold beer deliveries from my wife, I finally got the phone back to stock version.
Rooted it again, motochopper, And loaded GoldenEye Rom v 8.0 . Still slow to little or no charging.
Loaded PACMAN and noticed something that should be mentioned.
Pacman rom has its own little battery widget that sits in the top tray and shows the %. It glows green from bottom to top to show that it is charging. I noticed on every couple of cycles, the battery meter would flash red for a quick second before turning green and sweeping up.????
Went back to a backup of GoldenEye8.
The current status
The phone is currently plugged in to the stock charger (2A) and stock cable. It has charged up only about 3% in 20 minutes time. I have it in battery saving mode with wifi on , and EVERYTHING else turned off.
Battery info says:
Temp 87.3 F
Voltage 4033mV
Plugged True
Charging
Li-ion
Health:Good
Charge Type : AC
Battery use shows 62% of battery use coming from SCREEN (Yes I have auto-brightness set, and NO live wallpaper)
Anyone have some good input?
Maybe its a bad cord? Or bad USB port/connection on the phone it self...

62% screen usage is normal, I sometimes see over 70% with my brightness all the way up.
Make sure apps aren't keeping it from going idle and staying active.
Battery temp. seems a bit high. General causes of that are a faulty cable.
Download greenify and hibernate any apps that may be running unnoticeably in the background.
If your kernel allows fast charging (disables access to phone storage while fast charging is on) enable it while charging if you're not using the phone.
Play with CPU and GPU governors in your kernel to save battery life. I.E: I put my CPU governor on "powersave" while idle and not using the phone for anything extensive.

Tried two other cords,but they just made it worse. They actually caused it to look like its charging but the battery level was going down.
Your second suggestion is probably right, but i'd like to exhaust my options first before having to restore and send to creator. I do find that with the stock cable and no external case on it stays plugged in well and doesn't make any "interrupted connection" noises.
With stock charger and cable and minimal functions running its charging about 1% every 4 minutes. ( Approx 6.5 hrs to full charge )
I feel like the hardware must be working in order to do that, and that the software is putting some kind of excessive strain on it. Possibly?
The battery use still shows, screen as the major contributor at 61% , so I switched from a really high resolution static background to a low res one. ( results to follow)
Downloading WanamLite now and going to try that out, also going to try performing the unlock procedure I did in reverse order and see what that does. Keep you posted. Open to suggestions.

Thanks for the advise, I'm running greenify and its really only showing facebook and my sms app, I hibernated facebook anyways just to test it, but I know out of the box , on a car adapter this thing was charging 1%/min , maybe I have a bad ROM/Kernel mix?

Doubt it, but maybe you can try going from touchwiz to aosp. Very much more lightweight, though you'll lose some s4 features. If it is faulty hardware/battery I'd just save yourself the trouble and swap it for a new one; or try another battery. I guess you can try doing a compete wipe and flashing a fresh ROM with a kernel you know will definitely run smooth with it.

Already tried the second battery, no luck. Any suggestion on the rom/kernel combo?
I use task650 with kt's kernel and it's excellent. Though it's all opinion, there is many great combinations. Some ROMs come packaged with their own kernel or a custom one.

IMO: those temps are pretty normal.
Why you don't try a bone stock rom and see how it respond for a few hours, if the stock rom behaves the same, probably you will need to send it for warranty.
