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.

Sorry, but what in your all's opinion makes for an "old" battery? 2, 3 years? or are we talking 4+ is there a way I could test my battery to see if it going bad perhaps?

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)

3. When you say battery life as half a day, what is your actual usage? Screen on time, Wi-Fi, 3g, calls etc?
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.

Will take a look, I kind of liked the battery stats option to compare to stats that others have uploaded, but I haven't checked out greenify.

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.

doh, yeah haven't touched it; and the life lessons continue (didn't know that about batteries). will try it out, if its gone its gone, lesson learned.

Yeah, I suppose I am pretty easy to please, I don't do games and don't really do video and don't feel that my phone is particularly slow (yet) so so far happy enough

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 a stock s4 battery for a while and recently its been draining pretty fast. I've changed roms many times but the end result is always still the same bad battery life. At this point, I'm wondering if my battery is just degraded. I drain 10 percent from 2 hours idle . Also, wakelock detector isn't detecting anything unusual.
Does anyone have experience with a degraded/bad battery? Besides a bad battery life, is there any other defining feature.

check to see if the battery is physically swollen; somewhat common problem for the s4. the swelling may only be slight, but if you're able to spin it on a flat surface, you should replace it.
Mine has been that bad since out of the box. Worst performing battery out of any Android I've ever owned. It's my only gripe about the phone except for the locked bootloader. Like you, I've tried virtually every ROM out there and its always the same issue. I was hoping a blacked out ROM would help but it hasn't really.
I ordered a zerolemon 3000 mah battery to replace the stock one. Hopefully this will fix any battery issues.

Interesting. Would you mind posting your experience back here once you try it out for a few days? I suspect you will need to calibrate it when you first install it too.

Yeah, I can definitely do that.
First, I just moved from a stock OS 4.4.2 in my Samsung S5 Us cellular G900R to an CM 13 Nightly build. Everything looks fine and the performance is just amazing. But I only have one slight problem. The Battery
The battery is draining when it's idle. I had fully charged it last night and when I woke up this morning it was 91%. Literally, it was doing nothing. And when I slightly using my apps such as WhatsApp and similar things it will deteriorate in a fast pace.
I heard that flashing a custom kernel fixed the problem for numerous users. I'm considering doing that, but I have another problem. I can't find any
Can anybody help me out? I mean generally with the battery stuff?
Note: I'm aware of the app hog problem that may occur from some misbehaving apps but that's not the problem. I'm monitoring the behavior of the apps from the system menu and by BetterStats Battery. Also I turned off the sync option and also the WiFi always on is turned off.
Yesterday I finally saw proof that the battery drain of my phone isn't normal.
When I updated to Nougat I also started using often an app that I, at that point, believed to be the cause of the huge battery drain I started experiencing. I thought that it could also be the fault of my two-years-old battery.
A few days ago I finally bought a new battery, and yesterday I decided to test the battery drain on my G5 with it.
I actively used that app (which requires the GPS, btw) for three hours at the same time on the G5 and on a Samsung Galaxy A5.
Results: At the end, I consumed ~60% of the Samsung's battery and... almost three full batteries of the G5*.
I can't believe it.
Is there a fix? Even requiring root?
*I have the G5's battery charger, which acts as a power bank, and 3 batteries, one of which is inside the phone.
It's something lg related if you want nougat just install fulmics 5.5 you will have almost stock lg firmware with great battery life.
Thanks, if that really solves the problem I'll definitely try it.
Is "qualcomm izat' enabled in location settings? This enables low power operation of the gps module

No, I didn't activate it because it said it would keep running even when the GPS is off, so I thought it wouldn't be worth it. I'll try activating it...
Sorry to bump an old thread. I have crazy battery drain at 1% a min. Is the root cause of your battery drain identified?
Howdy! A few weeks ago I noticed on my phone that the battery did not last as long as before. I said it would be from the software and I decided to reinstall it. First, I switched to a custom ROM (Pixel Experience) and there the battery life was even worse. Then I went back to stock ROM and it seemed to work better, but the battery was still discharging too fast.
I put an application for measuring battery life (AccuBattery) that told me that my battery (one year old) was at 79% life (3100 mAh). I replaced the battery with a new one. Surprise! And with the new battery still at 79% life it says it is. And the same 3100 mAh maximum capacity. I tried all kinds of methods, all kinds of custom ROMs and it all works the same. What could it be? Has anyone had a similar problem?
Thanks!
Nope. No issues with mine. You said you changed the battery, so you opened the device? I'm not inclined with HW too much, but since you've tried the most drastic solution software wise (flashing custom and MIUI ROM) then it could be a hardware issue by this point.
Again, not a hardware guy, but maybe there is a loose wiring or connection (to the battery) or maybe a short-circuit. If you need further help maybe ask help from a repair guy. But that's just my take (possible hardware issue)
