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.

Looks like I'll be keeping my s2 longer than I thought. One of my main criticisms of it is battery life. Currently < 4 hours screen time is normal for me (actually pretty good as other roms were struggling to get 3 at times).
How much actual difference does it make? I'm not interested in tweaking voltages or under or over clocking btw, as tried all that and they introduce their own set of problems IMO. On paper the difference is only about 20% but I've heard some say it makes more difference than the paper figures would suggest?
Improved battery life would solve one of the phones main limitations for me.

Yes it will make difference. How much depends on your use.
If you unplug at say 8 am and your phone dies at 5 pm, this bump will get you pass 8 pm.
Less than 3 hours?!!!
I use mine virtually all nite at work (9 hour shift), I watch a movie, flash new ROM's, surf, text, you name it........ and I've not a yet ran out thru the nite!!
And then I charge it for about an hour or so before finishing, and again when I come back the following nite, before it all starts again!!
That's why I said, depends on use, and therefore put an example.
Should not be taken literally.
Yes. Been using one for > 6 mths & definitely better than stock battery (obviously, as you'd expect). How much difference does it make ? Approximately 20% I've found over an average period of 'mixed' (within a charge light/moderate/heavy usage) use (again as you'd expect given 2000mAh is a bit over 20% > than 1650mAh). More difference than the paper figures would suggest ? Lots of people on XDA make all kinds of outrageous/ridiculous claims about lots of things (battery calibration anyone ? ). I'll leave it at that.
I guess I was lucky as my I9100P came as standard with a 2000mAh battery.

Getting these extended batteries doesn't really help alot. You need a good kernel and ROM combination to get the best battery life.
If you're using ICS, Get Fluxi XX Kernel. Resurrection Remix and Fluxi will vastly improve your battery life. With heavy use, I can get 12-odd hours out of my battery. You also need a good modem because crap modems are battery hogs.

I've looked at that ROM, and although it looks nice enough, I don't see any compelling reason to change the one I'm using, which, although it doesn't seem spectacular on battery life, is actually as good as most other ROMs I've used (and certainly better for me than the likes of CM9).
I've tried the whole undervolting / clocking, and just end up with a device that runs more "choppy" than as standard, and that annoys me more than having slightly iffy battery life.

Well I thought about this yesterday, basically from 100% to about 5% the phone lasted about 15 hours, and with just under 3 hours of screen time.
If I kept the configuration of the phone the same, I'd be getting approx 30 minutes extra screen time and about an extra 3 hours of standby time.
Realistically, it doesn't seem worth it. I'll probably just do what I do now and if I know that I will need the phone later in the evening, just keep it plugged into my USB cable at work when I'm not using, and, if necessarily, take my charger with me. Its not really a big deal.

You don't need undervolting/clocking to get good battery life. You just need a good kernel. My device isn't choppy at all and I've got my max clock speed set at 1.3 and I'm really happy with my battery life.
If you don't like the look of NeatROM, try Resurrection Remix, which Fluxi or N.E.A.K kernel.

An old thread I know, but somebody might find this useful.
There are 2000mAh batteries on eBay (for example) that are the same physical size as the standard battery. In fact these are just 1650mAh batteries with a different label. There are also genuine 2000mAh batteries that are slightly thicker (and more expensive and come with different battery covers) that should logically give 17.5% more life as (2000 - 1650) / 1650 = 0.175. I haven't tested one myself but this seems to match the 20% extra that others have mentioned.
My solution was to buy a battery charger and 3 spare batteries from eBay plus a retractable USB charging/data lead (all very cheap). These batteries are labelled 1800mAh but I doubt they are - they last no longer than the original 1650mAh one, but they were cheap so who cares?
When I'm at work I plug my phone into my PC if it needs it and when I'm driving I always charge it in the car cradle. If I don't have the opportunity (or forget) to charge it and the battery gets very low then I simply slap a full battery in and recharge the flat one. Changing batteries is quick and easy if you discard the nasty standard battery cover and use a Samsung mesh or Casemate case to hold the battery in and protect the phone. Works for me.
Definitely worth it, I have had one for a few months now. Stick with OEM tho! Got mine for $25 USD shipped through eBay. Had to hunt for weeks to find that and the seller was sold out in a day or 2.

How can paying over 5 times more for 20% extra battery life possibly be worth it? The cheapest 1650mAh battery on ebay.com is currently $4.99 with free shipping. Samsung OEM batteries perform no better than cheap knock-offs in my experience.
Hi,
I bought a brand new "Chinese" battery of 2430 mAh because my stock battery was lasting nothing. My stock battery I must admit I did not take proper care of it, I pretty much charged it every time I had a chance, without waiting for it to be empty, so I thought the battery was just bad because I took bad care of it.
With this new battery, the first thing I did, was do a complete wipe out of my device. I cleaned the internal and external storage (formatted the internal storage and I got rid of all pictures and crap from the external sd) and I did a fresh install of the RootBox rom with fluxi kernel.
The problem is, battery drainage is still a huge issue with a fresh rom install.
Just leaving the phone sitting on my desk for an hour (not actually using it), drained the battery about 10%.
Could this be an electrical issue with my phone? Is this ROM related?
I've heard most people can make their phone with regular usage, last for at least 10 hours. Mine barely survives 4 hours with normal usage.
I look forward to any recommendations or tips on how to fix this problem.
Thank you!

There's no such thing as "regular usage" or "normal usage".
You may not believe this, but surprisingly you're not the first person to complain about battery life. If you bother to search (it's the very first rule of the site), you'll soon find what's recommended to others in order to track down what might be using up your power.
Good luck.

I know i'm not the first (nor I'll be the last one) complaining about battery life. I have tried hundreds of suggestions on how to improve battery life but I think my situation is a bit unique and different. We are talking about a brand new battery, with almost double the size as the original stock battery, a fresh rom install, and the battery draining 10% of its juice while sitting on a desk without even turning the phone on.
I would like to know if this is normal, if it could be an electrical issue, something wrong with the internals of the phone, or is it a software issue, etc.

If you're asking whether it's normal to try and justify yourself as having a unique problem, then yes, it seems it is. You're not unique, and it would be impossible for anyone to answer your question accurately with the minuscule amount of useful information you've given.
By the way, just because a battery claims to be 2430mAh, doesn't mean it is, and judging by my first few results on eBay searching for that ... well, yeah, right, I wouldn't expect it to be much more than 1400, if that.

I agree with this. You need to get a name brand battery, or an official samsung one to be sure about the stated and actual mah of the battery. I have two anker 1900mah batteries and I believe they are very close to that

Hi, I have a problem with my Ace. When I only use 2G and use my phone for calls/sms, my battery lasts for like 3 days. But if i have 100% full battery and I use the internet with (or without 3G), my battery lasts for like half an hour, drains from full to 0 and then phone turns off. If i turn on my phone again, it shows like 30% or more battery left, but if data connection is still on, I lose 1 percent in like every second.
This is not only with data connections. I drained my battery from 100% to 0 in like 1,5 hours with just looking some pictures and using the calculator. I would like to think my battery is dead, but it lasts like 3 days when used for calls/sms only.
I have tried recalibrating my battery many times, used different ROMs (stock and custom), still same.
Is there anything else I could do to check my battery status??
Anyway, I am looking for a new battery but not the original one. Im looking from eBay. I contacted the sellers and asked for the weights. Original battery weighs like 30g. I got replied that these two (2050mAh High Capacity Replacement Battery for Samsung Galaxy S5830 and aoonen 2PK NEW Li-Ion Battery for Samsung S5830 Galaxy ACE 1800mAh fast shipping) batteries weigh 50g and 60g. This makes them less likely to be the fake gold ones, or what do u guys think? Has anyone bought one of those batteries? Or can anyone recommend a battery with more capacity than the original one (1350mah)
I accidentally hit "thanks" button instead of reply
I'm 100% sure that something is wrong with your battery.
I've never heard about such long-life battery in Galaxy Ace.
3 days calls and texting ?
It's normal that battery drains faster when using mobile data, but not that fast.
If You can, ask a friend to borrow You battery from Galaxy Ace.
If everything will be okay then You'll know the naswer.
If other battery won"t last longer, then i suggest to check you phone for "short circuit".
Maybe something is wrong with your motherboard that is connected with 3G .. ?
okay thanks, can I use the battery from S5830i?

If anyone wants me to do this test (properly) let me know.
Thinking about this; perhaps a few Ace owners could flash a common ROM and perform a standard discharge test. This would give us some baseline.

My batter is two years old and it works good.
I use CM7 and no super widgets. Maybe it saves energy.
Try another ROM, remove or switch off everything You don't need.

There's an app called "Battery Drain". Try charging your phone to 100%, turn on Battery Drain and select everything except Vibrate, and let us know how long it takes to fully discharge.

Wow, just too many variables! For instance.. Any idea how many mA the vibrator uses when typing with haptic feedback? What about the extra battery used by the radio when your in a poor reception area, does my micro-sd use more power than yours? Etc.
Battery life comparisons will only be meaningful in conditions where the battery is the only changed variable. So i would charge two or more batteries; discharge one, then another, measuring the times. Both batteries would need to be new unless you just want to compare something tired and worn with just out the factory.
Not 100% but I think it's relevant how many amps you take at a time, in relation to total capacity.. The chemical tech. may be difference, but lead-acid cells give differing amounts of charge dependent on temperature, and rate of discharge. In most applications capacity (C), is measured over 20 hours (C/20). C/100 will see many more amps capacity, and C/10, fewer! Also consider a used battery could last a considerable time, if only the high drain occasion is minimal. Something simple like the vibrator could send an old battery 'over the edge' if the drain is too high.
What does all this mean to me? Unless you wanna spend hours discharging your phone battery finding out (not really), get a fresh battery online; they still don't cost much and are easy to find. Gold batteries have been available for some time so go with your gut on that one! Perhaps, like me, you think it's worth the risk.
If you really love your phone and think you'll still be holding on to it in a couple of years time - you'll be thankfull you bought a spare battery or two while they were still cheap
Peace!

Hello, problems of battery are the most important in the management of smartphones increasingly sophisticated. I know of no silver bullet, so it makes sense to always have an alternate (note that battery life depends on time, even without use)
I found a small application, very cool, which is PowerTutor, which gives us interesting information from the battery usage. However'm with JuiceDefender Ultimate (free version exists). The only application which effectively spare battery was Greenpower. [all in gplay]
I hope I helped
new battery
Hi, new battery from ebay :laugh:, now lasts a day under normal use and a day and a half with little use of the internet.
Not bad for the low price
Seems that lastmyth that is not worse than the others in the use of battery.

This is usually the fix. It's amazing how fast some batteries start failing. Old batteries and cold temperatures are usually the top cause of poor battery life, especially in secondhand phones.
Try Juice Defender :thumbup:

So I am currently running Carbon Rom on my phone. Whenever I lock my phone and I unlock it, in the notifications, it says that its preparing my storage everytime. But now, it says that my SD card is blank or unsupported but it works perfectly fine my computer. I've had this problem for about 2 months now. I've already tried changing the rom and clearing the cache. Also, I tried to take out my SD and put it back in but not luck. So please help on that. Also, I was just wondering, so as you already know, I'm running the Carbon Rom on my phone. It's a great rom but the battery life sucks. I would like a rom similar to Carbon that is 4.3 or 4.2 that is very smooth and also has great battery life. I tend to use my phone a lot, and I know that battery life on androids suck but some other roms had much better battery life on them, but I didn't really like them much. Thanks for all your help!
Played with Carbon and other roms, none are close to the battery life of Shostock roms (I've run 2,3, currently 4). And SS is about tops for smoothness and stability. Some of these roms are so much worse on battery life that it's pointless to use them if you actually "use" your phone throughout the day, unless you have it plugged in everywhere you go.
Far as the SD card not sure there, did it do it on stock or any other rom?

So I switched to Shostock 4.0. It's pretty smooth but my battery life isn't so hot. Maybe I just have to give it a day or two. And the problem isn't happening now. But usually, the problems comes after about a week of using a rom. Also, sometimes, there's random reboots.

I do know Sho roms are always tops for battery life of the i777 roms. Never had random reboots or anything on any of the Sho versions. There could be something else wrong with the phone, rogue apps, something killing on gps power, battery gone bad. These phones are two years old now, and a lot of people have had the battery itself go bad before that time, I just replaced mine like a month ago. Just randomly started getting worse and worse phone life over the past couple months.
I keep GPS on all the time, and sync etc, only thing I adjust is WiFi set to stay on in sleep mode only when plugged in (Android has always had that battery sapping wifi bug). You should try running stock though for maybe a week or two and see if the issues occur, if they do, it could be hardware issue.

Random reboots are usually due to a kernel issue, rather than a ROM issue.

Everyone will get different results, period. I get great battery life with Carbon, drop maybe 40-50% over the course of a day. Much of the building I work in, is a black hole when it comes to cell coverage, so I'm happy with my results.

So your not using your phone since there's no cell coverage? That's the thing I'm on my phone all day for work/personal, ton of calls, emails, text, browsing etc, used a bunch of roms but always come back to Sho on the i777. Have two employees with i777s running Sho too, same results, none of the roms they used had the standby and in use efficiency. Not to say the roms are bad, Carbon is cool, just wish they all had better life.
I will say if you notice a big difference like I did over last few months, time to replace the battery. Sammy shipped crap batteries in these phones, and it's a known issue that majority fail before two years are up. Mine did and my employees did lol

Yeah, so, I switched back to jeboo kernel but the battery life sucks! I'm going to wait a day or two and see if the problem goes away. Also, on this rom, I also sometimes when I unlock my phone, it always says preparing SD card. Its annoying.

If your having these same issues across different roms like you are, run stock for like a week at least and see what happens. Not sure what you mean by switched to Jeboo as Sho4 comes stock with Jeboo tweaked for it.
Also if battery life is sucking that bad especially on roms known for battery life, 99% sure its time to replace the battery. Samsung shipped crap batteries in this phone that frequently die between 1.5-2 years. I've replaced mine, two employees have, few other i777 friends have etc.
How long have you been owned the phone's battery? The above poster mentioned battery usage which (if you're still rocking a day 1 release S2) the battery is at the 2 year mark. Might be time to get a replacement battery.
This one is a weird one...
About a week ago, I needed GPS to navigate out of a town - I waited and waited and didn't get even any satellite reception... It turned out that I found the way by myself and just closed the navigation. A few days later, same situation, no visible satellites at all... Didn't have time to reboot the phone, so I just closed the navigation and went my way.
Now, something weird is going on with my phone... Usually I get about 2 days of battery life - but since last charging, it looks i will get about 4 days and I have been using quite a few apps, browsed the net, made SIP phone calls, made normal phone calls... (more than normal usage for me anyway).
Is it just me or are those two things connected in any way? Can it be that GPS has crashed somehow and in the result, lowered the power consumption of the phone? Is it possible to turn off the GPS 'on demand' to extend battery life?
All other stuff is working like a charm...
I am using stock ROM (4.1.2, radio: I9100BULS1, build: JZO54K.I9100XWLSD)
Why do not you try installing a different rom see why.

Well, a colleague of mine has the same phone and has experimented with various ROMs - none gave him so much more battery life. It is not the question of which ROM is better in terms of battery life, but whether some weird (non-functional) state of GPS (I have it normally disabled almost all the time via drop-down menu) can cause the extended battery life. And if this is possible, can this be done on purpose?
The ROM stock give many problems, you're not in fact the only that the strikes. I advise you to try some Sammy Rom! JellySNAP v6 and, for example, a great ROM based-stock Sammy

I am bumping this topic to continue the discussion...
I am aware of other ROMs and have experimented with a lot of them on another phone. Due to extensive set of installed applications, loads of data and relatively stable stock ROM, I haven't really taken the time to do the transition.
So, I am not really looking for a solution to fix GPS, but the opposite way. I want to know if I can break GPS on next boot in order to obtain such long battery life... How many days of inactivity do you get with non-stock ROMs? At the moment, I am getting 5 days of light use WITH stock ROM (WiFi, Bluetooth, data disabled, only connected to mobile network to accept and make calls). I was never been able to do more than 3-4 days and my battery is now over 2 years old....
So, please, don't try to persuade me to install other ROMs by stating that they are better and more stable - list your battery lifes in case of light use or inactivity.... Do you get 5 days on 2 year old battery?
If you think breaking GPS is somehow responsible for greater battery life, you're going to end up rather disappointed. That concept defies logic given GPS only uses battery when you're actually using it. How is it possible for battery life to somehow magically double as a result of GPS being 'broken' ?
Thus far you've not provided one duplicable 'test' that other people can try to see if they get similar results, and all you've done is blabbered nonsense in a couple of posts. I mean, do you honestly think people here are going to delete a bunch of GPS system files to see if they can get some magical extension in battery life ? I know I'm not, because trying to put that stuff back when your silly theory doesn't work is a pain in the arse.
Did it ever occur to you that given the battery is two years old it's quite probably on its last legs & is very likely chemically unstable (this is why 'old' batteries swell up & sometimes even burst). This instability might be causing the extra battery life as the battery approaches the point where it's no longer useful. Put it this way, that's far more likely than busted GPS causing the extra battery life.
So, please don't try to persuade us that breaking GPS somehow doubles your battery life with a 2 yr old battery. Logic & almost 3 yrs worth of different people's experiences on here with this phone just don't support your ridiculous assertions.
That was a spicy reply, MistahBungle
Some facts:
- No system update was installed in the last month
- No application has been removed
- System hasn't been rebooted for a month or so
- Never got more than 2-3 days out of battery in idle
- Battery is 2 years old and is physically not damaged or swelled
- GPS isn't working (not even receiving or predicting a satellite on a clear day)
- System is rooted for a year or so
- Battery lasts 4 days now (instead of <2days a month ago)
- Connected to 3G network (no data connection)
I would try to reboot my phone, but I am afraid that it will all be over...
So, to stay with firm facts - how much battery life do you get with alternative ROMs in real life? Is 4 days (5-6 days with new battery) something usual?
That concept defies logic given GPS only uses battery when you're actually using it.

Can you then explain me the difference between Cold and Warm GPS start? As far as I know, phone tries to keep as accurate GPS time as possible and a bunch of ephemerisis data in order to decode GPS data faster, next time you enable GPS. This defies logic that GPS is completely OFF when it is 'disabled' by GPS button in Android system.
I mean, do you honestly think people here are going to delete a bunch of GPS system files to see if they can get some magical extension in battery life ?

No, I don't expect it to. I am looking for information whether anyone experienced anything similar.

In Lithium-powered batteries, I haven't come across the fact that battery capacity is increased with battery ageing and sweling up... On the contrary, internal resistance goes haywire and capacity drops, contributing to even more heat being spent internally by the battery and speeding up the process of degradation...
I may have not been cooking my own ROMs and writing drivers for phones, but I have quite extensive background in embedded systems and electronics. Battery life can not increase just by itself - there must be a reason... My lifestyle hasn't changed, my environment also didn't change, other phones at home didn't experience such battery life extensions... The only thing that I noticed is that the GPS is not working. I opened this topic in order to discuss whether that's the true cause or not.
So, based on '3 yrs worth of different people's experiences on here', what could be the cause for such prolonged battery life? How can I debug it by myself without rebooting the phone?
