Has anyone else had battery drain issues with the Eclipse ROM on the Verizon Galaxy S4? I just came from an S3 on CyanogenMod I'd been using for a little over a year and I could still make it a whole day without having to charge it, but it seems like I can only make it half a day on the S4 before the battery gets low. So far I've:
-Used Titanium Backup to remove all bloatware listed here: http://forum.xda-developers.com/showthread.php?t=2797600
-Minimized screen brightness as much as possible
-Turned off all unnecessary functions (Gestures, AirView, etc)
-Turned on Power Saving Mode
-Replaced the original (used) Samsung battery with a brand new OEM battery (with no positive change in battery life)
I mostly use the device for email, web browsing, etc. and still find the battery draining faster than I think it should be (about 10% every 15-20 minutes during use). I do have Avast Antivirus and My Data Manager running, but they only contribute to about 2-3% of total battery usage. The display, on the other hand, is responsible for anywhere between 30-50% of the total battery usage. (I can post screenshots of my device's battery usage later, if necessary).
The S4 is on the NC5 bootloader (thus I used the Safestrap method to install Eclipse), if that makes a difference.
Im on eclipse nc5 and i actually get great battery thanks to xposed and greenify. Go install greenify, And grant it root access. Then any apps you dont need notifications immediately, select them to hibernate so they dont use as much battery. That should help, and with brightness. Use lux lite. It can make your screen as bright as 100% or as dark as -80%. I change it depending on my lighting, and it seems to work fine.
When you say you get great battery life, just how much are you getting out of it? I've got greenify installed, hibernated all apps I don't need notifications for, etc and I still average only about 4-5 hours of battery life. Surely the screen alone can't be draining the battery THAT fast?

You may have wake lock issues with some of your apps Android Basics 101: Understanding Wakelocks: http://youtu.be/fG8tghj0AYM that is a very good and short video explaining what exactly a wake lock is and there is a good X posed module that will help you manage them.
"It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery." - Galatians 5:1
I'm no pro or anything but I do know that eclipse should definitely last at least a day. If greenify or freezing busy apps isn't doing it, then you have some other problem. If I were you, I would reinstall the eclipse rom, check the md5, and reflash it. Even preferably, I would do a clean restore of the s4... This is a ton of work but that means that anything wrong will be fixed, its the solve all solution.
*assuming you're not streaming videos constantly off 4g while running your gps in the background and having 10 emails pushing in a hot car . then u might have some bad battery life, just maybe.
I have basically the same setup, but I use One Power Guard as well. I also used Titanium Backup to freeze anything to do with Google since I use Aqua Mail and CalenGoo, neither of which need Google services. Mostly email, phone and texting. Probably much less use than you, but I get two days easy, One day I'll have to use just the phone for a day and see what happens.

Sorry for the late reply, but I finally got around to doing a clean restore of the S4 followed by a reinstall of the eclipse rom (including redownloading the rom and checking the md5). A few days later and my device's battery life is still terrible. I know there's always the possibility that the brand new OEM battery I purchased a month or two ago could be a dud (I did buy it off eBay, knowing full well the risk I was taking). Any suggestions on where I could get a good battery for a reasonable price? Or can anyone think of anything else that might be draining the battery so fast?

Buy an Anker or Zerolemon! Both are great.
Download wakelock detector or better battery stats to check what apps are using your battery.

it seems that ever since i rooted my phone til today that my battery life has gone down. alot. i don't really use it heavily but yesterday i drained it to 54%. before in a days use the max it would go down to was 75%.
my batt voltage always is around 4000 mv. i also have the free juice defender app i put on yesterday. i have done the battery recalibration but i'm not sure if i can do it right because of the clockwork recovery booting up when i plug it in when off.
i'm running CM6.1.1 any thoughts? any help will be appreciated.
i have looked at the other batt threads but didn't find anything that fits my problem.
or is all of this normal after a new phone and i'm just being paranoid?
i also have spare parts.
i would recommend this thread, but it sounds like you've done that already.
i would just re-check all of your data/refresh settings...i've never really noticed battery decrease with cm mods...perhaps try CM7?
just installed watchdog lite, will post back with more info.
I'd say it's normal for a new phone. A couple things to consider:
- Low screen brightness
- turn wifi, gps, data off when not using it
- you might consider turning off auto-sync for things such as gmail
I'm sure there's a lot more you can do i just can't think of them right now.
I was getting ridiculous battery drain a while back when I first started the whole rooting and flashing process it was a brand new phone. The thing I did was just reflash whatever rom I was trying to set up. It greatly improved but I don't know if I had messed up with flashing initially then just properly flashed the second time around.

yes, i have done all those things.
Hello all! I have been a silent user of these forums for a while now. I am finally turning to you all for some help because I am unable to determine if the issues with my phone should be treated as related or unrelated.
My phone: Image attached, no outside URLs. In short, Galaxy S2, ATT, 4.0.3, not rooted.
I have had this phone since about March. Ironically, I had a model of the captivate that was subject to the random shut offs. ATT worked with me and since my upgrade was so close, they moved it up a bit. Badaboom this phone. Enough with the stories.
Applications: Some utilities I have on this phone include juice defender, advanced task killer, onavo data manager, eco battery protector. I do admit to the use of applications like instagram, facebook and browsing through some websites, but the effect on my phone is not necessary what I am looking to fix. Also, I use ADW, but I have been a long term user of ADW and find it to be light on my battery usage. Never even shows up in my battery summary. I just feel you should know.
The issue: My phone is being a pain in the rear. I am trying to determine if my overheating and poor battery life are related. When in idle, my phone can drain within about 5 hours. When I first started noticing this, I would make sure wifi and sync were off 'cause I really didn't need it on at work. Still, maybe saved myself 45min of battery life in idle (some screen usage to check time and w/e). Then when I charge, the phone gets so hot I start to worry. I was used to my captivate getting kind of hot, mostly because of the cheat cover, so I've stopped using it and charging with it. Right now, I mostly use a dock to charge my phone overnight, but still, when I take it off its hot as Hades.
Usage: I have noticed a significant difference with juice defender on/off, maybe about a couple hours worth of usage. Usage for me is usually gmail, texting and sometimes yahoo instant messenger. (Yahoo has been pretty light on my battery, never really noticed too much : I have noticed a significant difference with juice defender on/off, maybe about a couple hours worth of usage. Usage for me is usually gmail, texting and sometimes yahoo instant messenger. (Yahoo has been pretty light on my battery, never really noticed too much and that kind of drainage is normal). Heavy usage might include me using my phone as my GPS when driving. I do this while plugged in otherwise it would be off before I exit my hometown. The overheating gets so so so hot that I might unplug it for a bit and turn the AC on. :crying: Also, I use things like instagram, facebook, gizmodo but I make sure to kill those tasks when I am finished using the various utilities I have. I make sure I'm on wifi when I use those and I have them set to only working over wifi with onavo.
Other Issues: Recently, there have been issues with charging. I have had random moments where my phone does not register it is being plugged in until I pull the battery. At first I thought it was my car charger and maybe the fuse on it was a dud but when I got home and tried my dock, it was still nothing. Then I tried USB to my computer and still nothing. After a battery pull, this was fixed. Happened about 2 times over the past 2 months.
.. I don't know what to do to get a balance back. This has been going on for about 2 months now and I can't keep looking for a power source a mere 4 hours into usage.
I am considering looking towards rooting and seeing what customization I can do to manage my phone better and achieve a balance right for me. I am familiar with the process and proficient enough to work through it. Due to my phone feeling too new, I have been avoiding it. I would hate to shell the money out for a new battery, given this phone is less than a year old.
Please please please gurus .... I need your help. I don't know what to do to get back to having my smartphone work for me efficiently.
Well first get rid of the battery savers. In my experience they crashed my brothers phone and don't save battery in the slightest. Just remember to turn WiFi and data off using a toggle. Also download betterbatterystats from the xda forums and cpuspy from play store and let the phone do its thing for a day

Task killers do nothing. Juice defender used to help back in GB days. No longer needed. Just use the phone normally. Also did u say yer on the stock ICS kernel? I was gonna suggest a factory reset to clear data and cache but if yer on stock ICS kernel don't do that.

The first thing I would suggest is to get rid of the stock ICS root then custom rom ICS after that get a little app called battery calibration, fully charge the phone and calibrate the battery i have used this app and swear by it as far as juice defender i have used it and never really cared for it it really never did what is said it would.
I'm trying to assist a non-technically inclined friend to troubleshoot her battery life issues. She's on a stock JB Vodafone ROM, and she lives a long way away, so me just going to see her and rooting the phone is a no-no.
Her battery dropped from 99% - 47% overnight, with the main culprits being android system, followed by device idle and cell standby quite a long way behind. The phone had wifi and mobile data switched off during this period.
I know android system is an umbrella for all sorts of processes that go on in the background, but since she isn't rooted I can't use Better Battery Stats to drill down and try and find the cause of her wakelocks. She doesn't have many apps installed at all, mainly just what came with the phone.
Is there some general stuff that I can do to try and eliminate any obvious causes of this battery drain? Any suggestions at all would be welcomed

Install gsam from play and let it run over night. Use it to inspect apps, but then toggle the view from battery drain to number of times waking device. Typical culprits are sync with numerous accounts and location services. Google Now has been know to beat up location services. Next install air push detector and remove any apps it detects.
Hope this helps.

When I upgraded my phone to JB i had to charge my phone twice a day, so I decided to do a factory data reset and now my battery life is about 20 hours, I'm installing one by one all the apps that I had and until now I haven't had that problem anymore.
You could tell her to do the same, and let me know if it worked. Good luck!

I had the exact same problem, but on ICS. I figured that Fast Dormancy was the culprit, keeping my phone awake for almost half the time it was out of charger. It solved itself on Jelly Bean, but I read a tip somewhere that might help.
1. Remove battery for about a minute. Re-insert battery.
2. When phone is fully charged, ONLY remove it from charger when screen is on and phone unlocked. If not, then remove battery and start over.
Dont know if this helps, but give it a try. Worth a shot. If not, factory reset is an option. Better Battery Stats is also good for checking wich processes keep the phone awake.

I have been trying out various 4.4.x ROMs (CM, Resurrection Remix, SlimROM) and had varying levels of success but the one issue that I have had consistently with all of them on my SGS2 is battery. 4.4.x seems to devour my battery no matter which ROM I am using (and the different ROMS are using different kernels usual). CM11 has far and away been the most stable so I have stayed with that but it too as failed to resolve my battery issue. I have never had much luck with battery life before but half a day is ridiculous. I thought about trying a different kernel but not sure that would help as #1 I would think the CM team would know better than I what would be the optimal kernel and #2 I have been trying different kernels anyway when I have been trying different ROMS as I believe the different ROMS have all had different kernels. Has anyone else had this issue? More importantly has anyone had any luck resolving this?
I suggest you to replace your battery. Beaware from cheap ones!!! I have I9100 too, i also try many methods to increase my battery life but i reach maximum 10 hours. Then i buy new batteries. It is not original galaxy s2 batteries but i think better than the original one.(1800mAh buy from ebay) Now i use RR kit kat rom with stock kernel my mobile data is always on and I go to bed at %35 percent of batteries.
1. If your battery is quite old, replace it.
2. Check whether you are having any wakelocks. Does it go to deep sleep?
3. When you say battery life as half a day, what is your actual usage? Screen on time, Wi-Fi, 3g, calls etc?
4. Betterbatterystats and greenify are your friends.

Thanks. My battery is about 2.5 years old, its an Anker battery, 1900mAh that I bought on amazon (I honestly don't know what constitutes "old" for batteries, is 2 1/2 years old?). As for ROMS I was actually running an older version of RR but had serious stability issues (related to sdcard, never was able to resolve it) and battery wasn't great (better than now though) when I upgraded to the newest RR I had some lingering stability issues and battery issues too so just settled on CM11 this time.

I am not totally clear on wakelocks and deep sleep, I have "Battery Stats" installed (guess its not the same as the betterbatteryapp but seems to give some similar info) but its not clear to me how to read it all. In this case it sayd the stat period is 3 hours 8 minutes and out of that it has been in deep sleep 1h 51m and running time 1h 17m and wifi time 1h 25m and my batter is down to 74%, I am assuming that is not normal? In terms of applications the hogs are defintely the two audio apps poweramp and dogcatcher (they are just at the top of the list, the numbers it gives don't really make sense to me)

Well I have a 3 hour idea of my usage above, I don't use 3 g, I have wifi on about a third of the day perhaps, and actualy screen time probably just an hour or two, I do use it quite a bit for podcasts and music though. But I had tried it with my audio apps uninstalled for a few days and it still drained fairly quickly.

If your battery is 2.5 yrs old, that's almost certainly the cause of your issues. Good advice to stick to original Samsung batteries; though there's nothing wrong with the 2000mAh genuine Samsung battery Vs the 1650mAh one - I used one of these for almost two years.

Doh, was hoping I wouldn't have to replace the battery. Actually... that said. Should a 2.5 year old mostly unused 1650mah samsung battery still be good? I think I still have the factory battery around somewhere now that I think about it. When I purchased the Anker battery I seemed to remember it was mainly for price and reputation reasons, not that the Samsung battery had such a bad reputation but the Anker had such a good reputation and a pretty good price.
I will give another battery a try if you say 2.5 years is old, but I do have to admit that the battery drain was not nearly as much of an issue with the older ROM I was using (RR 4.2.x) before, it wasn't stellar but not like this so it seems to me its more than just the batter thats giving me problems here.
Anyway, my phone is still golden other than the battery issues so if i can squeeze another year and a half out of it I'd be a happy camper. Any other thoughts would be welcome (and appreciated!)
Batteries discharge over time if they're stored/not used, ideally you should charge it up to/keep it at around 60-65% every few mths if you're going to store it for that long. If you've not touched it at all in that time, it might not be able to take/hold a charge anymore because that wasn't done.
Only way you're going to find out is if you charge it & use it.
Yeah, if you ended up getting 4 yrs out of a smartphone you'd be rather happy indeed.
If you really want to satisfy yourself as to whether it is indeed the age of the battery you're currently using causing your problems, do a clean install of stock & test that for a week. If it does the same thing with stock, you'll know for definite it is the battery. I'd be very surprised if it isn't though; they're not designed to last much longer than what you've had yours if you're charging/discharging constantly.

Thats a good idea, given what you've said i don't doubt that a large part of my problem is the battery (like I said before, with the older rom it was better but not stellar) do you know where I can find a stock rom nowadays? (sorry on the ROMS page they all seem to be custom roms, or perhaps i missed something?)
Thanks!
Stock roms @ Samfirmware, get one for your carrier/country (not 4.0.4 though, anything else is fine), if there's only 4.0.4 for your carrier/country, any other stock rom will do really -I just tell people to stick to carrier/country in the first instance as these have modems bundled with them that should have been tested by the carrier to give most people on their network good connectivity most of the time.
Or, Wanam has a thread in one of the development sections (I forget which; do a search or have a rummage around) that has CWM flashable stock roms if you'd prefer to do it that way; haven't had a look at the thread for a while so not sure if links are still live, but Wanam is a very active dev & I'd be surprised if he doesn't still have them hosted somewhere.
Does it drain more at a locationw where you use a certain Wifi?
I'm asking cause wlan-rx drains are know Android phones in big open Wifis as the phones get bombarded with signals from other computers/phones and are not filtered and keeps the phone awake.
Easiest way to find out is using Betterbatterystats.
I've had my Redmi Note 2 since August or September of last year. When I initially received it through GearBest, battery life was horrendous and the phone was hot all the time. I frantically searched for how to install custom ROMs, and after many hours of hopping around sites, I figured it out and fixed the issue. Battery life was quite good from then on out, and I rarely finished a day with less than 70% battery and an hour or two of SOT. I still got the impression that my battery life wasn't as good as the people who were getting 4+ hours of SOT, but I couldn't really complain since I'm not a super heavy user. Changing from MIUI to AOSP and CM based ROMs didn't seem to have a big impact.
Fast forward to January and I suddenly started ending days with 50% battery with minimal usage while on one of the first CM ROMs made by Bule. It seemed to happen all at once. This was around the same time as I got my Mi Band 1s, but after installing Gsam battery, trying different ROMs, and going a few days without the MiFit app installed, I determined that it wasn't anything related to having the new device connected to the phone. Nothing seemed to suggest that any apps I had installed were sucking more battery than they used to.
Then, about a month ago, my battery life took another dip and I found myself finishing days with 20-40% battery left with only an hour of SOT. I'm often at 60-70% as I leave my university in the early afternoon, and I hardly use my device at all during class.
Currently, I seem to lose about 1% of battery per minute of SOT. Standby isn't too bad, but definitely not as good as it used to be. Having problems across the board suggests to me that my battery may be faulty and dying slowly. I purchased a new battery, but it hasn't arrived yet.
If the new battery is clearly better than the original, then the problem will be solved. But if it seems to be about the same, then it's possible that it isn't the battery's fault after all and I'm doing something stupid to drain my battery. Update: New battery does not seem to be helping.
Does anyone have any suggestions? I've tried to use the Redmi Note Tool app (making sure to use the setting for CM), but I've seen absolutely zero change in battery life. I've changed ROMs at least twice since the problems arose to no avail. WiFi and Bluetooth are on all of the time, but articles I've read seem to suggest that these things are rarely to blame for poor battery life. GPS is used occasionally but isn't on consistently. Screen brightness is set to Auto with the bar below half.
Update: For those who have helped and those who may have similar issues, I believe I've found the solution. After completely re-installing the original China ROM with Fastboot and the MiFlash tool, the issue seems to be solved. I really have no idea what the issue was, but it was clearly something pretty fundamental that wasn't getting reset with TWRP wipes and ROM swaps.
Just in case someone wants it, here are the guides I followed:
ROM: http://en.miui.com/a-234.html
TWRP: https://felixsenada.wordpress.com/2...ng-twrp-recovery-and-root-redmi-note-23prime/
If you have twrp I suggest you to take a backup of the current rom and try messing around.
1. Try 3C Toolbox Pro or any free app tha allows you to change the permissions/freeze etc running apps. Change the apps tha start with the device. Freeze some unnesessary just for the sake of testing.
2. How many apps are you using? Not the ones you have installed and sittings, but actually using everyday. Did you install any in the same period you noticed things go sideways? 1% per minute is not a good sign.
3. Install wakelock detector and monitor what is draining your battery over time.
4. Clear cache/davlik through twrp and wait the phone to recreate the files. Maybe thats just it.

Thank you for your response.
I will look into 1 and 3. As far as apps go, I have a total of 51 apps installed (in the drawer including all the pre-loaded apps), but I only use an absolute maximum of about 12 of them, and on an average day, I only use a handful of those. The only things I can remember installing around the same time I first started having issues were Google Fit and Mi Fit. However, neither showed up in Gsam as suspects, and after changing ROMs on at least one occasion, I didn't reinstall them just to make sure. I still had the same issues with or without them.
4 is something I do regularly whenever I change ROMs, so I don't think that's the solution.
Just to make absolutely sure that I hadn't already overlooked something, this morning I turned off auto brightness and location. It's still too early to tell, but I think turning off auto brightness may have helped.
Nice. Lets see how this goes.
charge at 100 % with screen off flash latest china stable via fastboot(not recovery) use phone for 3 days like this(i now it's a pain but its worth trust me) .
flash twrp via fastboot than flash xiaomi.eu 7.3.2.0 and super su .
4-5 hours SOT assured (assuming your battery doesnt have problems)

I've had my Redmi Note 2 since August or September of last year. When I initially received it through GearBest, battery life was horrendous and the phone was hot all the time. I frantically searched for how to install custom ROMs, and after many hours of hopping around sites, I figured it out and fixed the issue. Battery life was quite good from then on out, and I rarely finished a day with less than 70% battery and an hour or two of SOT. I still got the impression that my battery life wasn't as good as the people who were getting 4+ hours of SOT, but I couldn't really complain since I'm not a super heavy user. Changing from MIUI to AOSP and CM based ROMs didn't seem to have a big impact.
Fast forward to January and I suddenly started ending days with 50% battery with minimal usage while on one of the first CM ROMs made by Bule. It seemed to happen all at once. This was around the same time as I got my Mi Band 1s, but after installing Gsam battery, trying different ROMs, and going a few days without the MiFit app installed, I determined that it wasn't anything related to having the new device connected to the phone. Nothing seemed to suggest that any apps I had installed were sucking more battery than they used to.
Then, about a month ago, my battery life took another dip and I found myself finishing days with 20-40% battery left with only an hour of SOT. I'm often at 60-70% as I leave my university in the early afternoon, and I hardly use my device at all during class.
Currently, I seem to lose about 1% of battery per minute of SOT. Standby isn't too bad, but definitely not as good as it used to be. Having problems across the board suggests to me that my battery may be faulty and dying slowly. I purchased a new battery, but it hasn't arrived yet.
If the new battery is clearly better than the original, then the problem will be solved. But if it seems to be about the same, then it's possible that it isn't the battery's fault after all and I'm doing something stupid to drain my battery.
Does anyone have any suggestions? I've tried to use the Redmi Note Tool app (making sure to use the setting for CM), but I've seen absolutely zero change in battery life. I've changed ROMs at least twice since the problems arose to no avail. WiFi and Bluetooth are on all of the time, but articles I've read seem to suggest that these things are rarely to blame for poor battery life. GPS is used occasionally but isn't on consistently. Screen brightness is set to Auto with the bar below half.

Update: I've been traveling for the past two weeks or so, so I haven't been able to respond.
I flashed the latest Xiaomi.eu build before leaving on the trip, but this did not help noticeably, so I can pretty definitively say that it is not an issue with any of the ROMs I've been using. Although it was never really suspected, I suppose this also confirms that it doesn't have to do with my house/work being in a bad spot for cell/WiFi or something odd like that.
Having returned to find my new battery waiting, it seems the battery is not the issue as I have been getting the same behavior today as usual (only a bit over an hour into the day from 100% charge and I'm already below 90% with 8 minutes of SOT).
Unfortunately, I haven't tried any wakelock detectors or other monitors yet since I wouldn't have had time to figure it out while I was away. I can look into this now, but my instinct says that I probably won't find anything that GSam hasn't been reporting anyway.
Finally, I did manage to get 2 hours SOT out of it one day (with lots of GPS usage as well!) and about an hour and a half yesterday, so I know that it isn't incapable of heavier usage; it just seems that it drains more slowly at random on certain days. The only other thing I've noticed is that, when the battery is draining more slowly, the 'Kernel (Android OS)' seen in the GSam screenshot on the original post drops to being about on par with 'Android System'. I don't really know what this would indicate, but maybe someone else could propose an educated theory.

Thanks for the advice, but I have some clarifying questions to make sure I don't do anything stupid that could brick my phone (an excuse to buy a Mi 5 would be great and all, but I really ought to do my best to make this phone work since it can do everything I need just fine).
Can any ROM be flashed via fastboot, or is there a specific one I need to download? I downloaded the china ROM from here: http://en.miui.com/download-274.html#396
Which method of fastboot flashing should I use? When I originally installed TWRP to get the original ROM off of my device, I was confused and bounced around many different sites trying to get ADB and VCOM drivers working, but I see now that there is a simple MiPhone fastboot tool that seems like it would work fine: http://en.miui.com/thread-145555-1-1.html
Do I need to do any wiping first? Normally I wipe via TWRP, but will the fastboot flash automatically get rid of all the data? Will TWRP be wiped as well since you reference re-installing it later?
Thanks for your help!

download fastboot rom here
extract it with 7zip , WinZip,Winrar (your choice)it's an archive basically since you have installed twrp that means fastboot drivers are already installed
now make sure u have twrp 3.0.2 by jemini since it's modded to not let stock rom overwrite twrp
so the recovery.img by jemini place it in images folder that you've extracted replacing stock mi recovery so you hit two birds with one stone .
than click the .bat file flash all
EVERYTHING must be erased EVEN INTERNAL MEMORY
