Hey guys. I've read and learned a lot from XDA, but there are some things I can't really understand or test by myself. So, I'm experiencing some trouble right now, and I need your help.
So, I've been testing roms since I bought my GS2. Almost 2 years later, my battery lasts 4 hours. I used to think the problem was the battery, so I bought a brand new one (sammy brand).
Well, it also lasts 4 hours, with CM10.1
So, I tried installing DorimanX kernel. The battery lasts longer now (not much)
I also searched a lot about Modems, and I read somewhere that changing modems would make the battery last longer. But I can't really understand why. Can someone help me? I'm really lost, I can't put everything together and understand this thing.
Please, help me answer some questions.
tl;dr
1- What is the best Modem out there? Can I install it using CM10.1, or is the modem bind to a ROM?
2- Why the battery won't last longer as the Android upgrades? My brother's GS3 (stock JB) saves much more battery than mine GS2.
3- What is the rom that saves most battery out there? As CM improves, the battery drains faster. Should I go back to stock? Does stock ROMs cosume less battery?
Thanks in advance.
(sorry about my poor english)

1. as far as i know using specific modem depends on the region & network. changing modem sometimes solves your problem, sometimes not. you need to try which suites.
2. install cpu spy, better battery stats and gsam battery monitor. check whether your device is going to deep sleep or not. if not see which app/process is consuming too much battery. 1- try callibrating the battery and then monitor it. 2-if that does not fix, enable aeroplane mode, then power off, power on after couple of seconds and disable aeroplane mode. monitor the battery. 3-if that does not fix check the battery stats log and post it in BBS thread so that some expert may analyze the log and provide you with feedback. make sure for each solution you give ample of time to monitor in order to narrow down the problem.
3. you need to try different ROMs one by one and use it for some time to know which suites your better on your need.

1. Modems are location dependant, so try to find the stock modem or one for the carrier you're with.
2. Battery depends on a lot of things. The apps you use, screen time, wake locks, signal strength, size of the battery, os version, how recently you flashed something, how many email accounts are syncing, apps that sync.. The list could go on forever.
3. As stated above, cpu spy to see if your device is deep sleeping and better battery stats to check the wake locks. If you flashed something recently give it at least 3 battery cycles before judging the battery life. You can also try to underclock your device if you are rooted and have a rom-kernel combination that allows it

There is an issue on JB that enables the media scanner nonstop. It has been draining battery like crazy. In some cases it drains 2% per MINUTE.
In my situation, I think that it's not my problem.
I'll check all your tips and give a feedback later.
Thank you very much!

I've got the results of the apps running
App usage -> 72% (50% is Kernel)
Cpu -> 48% 200 MHz and 39% on Deep Sleep
Partial Wakelocks -> NetworkLocationLocator (45min), etc
Kernel Wakelocks -> vbus_present (7h), PowerManagerService (3h), Multipdp (1h25min), etc
So, what are your suggestions? Should I downgrade to stock rom with siyah kernel?
Nowadays, I'm focusing battery. I want it to last a full day with moderate use. Today I didn't use the phone (at all) and it last 12h, with 20% remaining.

Hi there
I recently switched to CyanogenMOD and also bought AWD EX and while having the phone set on battery save something seems to leach the it empty fast within a day and not using it even a lot.
I am not very familiar with Android and finding what process might be responsible for the battery drain.
Any idea? Is CyanogenMOD or ADW EX very battery demanding?
First try out BetterBatteryStats to see what is keeping your phone awake.
Did u battery wiping/calibrating before/after flashing ROM?

yep, download betterbatterystats, (xda edition would do) then look for processes that use a lot of time, not those with few seconds. If there isnt any, look for any partial wakelocks that also, use a lot of time and root out the battery draining application.
If nothing seems to be wrong, i suggest you download battery calibration app from market : http://bit.ly/x5sPR6 and calibrate.
Cheers

@cekuhnen: The most often experienced problem is that the CPU never actually sleeps. Go to Settings > About phone > Battery use and if "Android System" is using the battery the most, reflash your ROM.

@the pic complain lol whats wrong wif the pic D:
@cpuneversleep. the cpu not sleeping is probably due to a wakelock thats keeping it from going to sleep. use betterbatterystats to sort out the burden app.
ah I did not calibrate the battery - So I will download the app and follow the charge and then discharge process?
I think I did this cash wipe fore flashing the rom. Why do I need to do this?
I have attached the screenshots from my Android system including the states
and as it looks Android System is what is using up 45% of the battery.
However again I have no idea how to read this or what it means. What are those wakelocks - I assume a process preventing Android to put the CPU into a lower MHZ frequenze to drain less power?

Why should I reflash it - what does it fix or do? I am asking because I do not understand the reason for this but would love to get educated
Wakelocos are processes tat cn prevent your phone from going to sleep properly, which may cause battery drain. It is under partial wakelocks(click the scroll down menu)
When you reflash your rom, your sort of "reset" it back to its "default" state, so anything tat may have affected the battery would be gone.

its just a reflash, all your settings will go back to default. its not a factory reset.
Ok I wiped clean the phone, reflashed the rom, did a battery calibration
but for some reason I still have the large feeling that CyanogenMOD 7.2.0 drains the batter dramatically faster than Froyo did.
When I woke up 40% of battery was lost within the 9 hours I slept.
When I only browsed the web a little the battery took another deep hit as you can see in the graph when Wifi got on.
However in contrast to before now the only two things taking up the biggest parts seem to be cell Standby and Phone idle. At last the android system is not doing it.
Considering that 10 hours of mainly stand by drains nearly 50% of the phone makes this a unusable situation. Mild browsing the web for 30 minutes killing 10% is just bizarre.
Do you have any other idea? I was under the impression that CyanogenMOD 7.2 has much better battery life but I feel at least how things work on my phone it is way the opposite.
Could ADW Ex be the offender ?

What kernel are you using? There is a kernel out there, I believe franco's that drains battery on standby. I had this problem to and therefore switched.
Yesterday I flashed adfad666's Unofficial CM7.2.0-RC0 and this one is using this Kernel:
[email protected]
What kernel would you propose to use which would work with the CyanogenMOD ROM I am using?
If you have a better combination please tell me.

I've always had battery drain with kernel .35 even though battery life is suppose to be better. For better battery and stability it's better, in my opinion to go with a .32 kernel. You have flashed the new baseband therefore you'd have to revert back but I don't recommend that. CM7 just announced official release and a nightly build is up. I'm giving a try (seems to be better responsive). This has a different kernel. It uses 2.6.35.10.
I actually do not have the new baseband installed - flashed I only flashed the Cyanogen ROM with the old baseband.
Thus I could easily flash any oldbaseband rom.
Anything you suggest?

Yes, I suggest AdFad666's A8 version of CM7. I then suggest to flash Goldenleaf.v111206 from http://forum.xda-developers.com/showthread.php?t=1227682
Don't forget to wipe battery stats after all of that.
Where do you get the A8 build from?
I only find this as being the latest:

Do I even need to flash this old baseband rom he mentions on his website when I never did change my old baseband anyway?

You are correct it's that version and no don't flash old baseband as you have it.

I just saw that he uploaded the A8 version so I downloaded it and will try to flash the .32 version and then the Kernel you listed.

Hey guys
So last night my phone was at around 90% battery before I put it to sleep for the night. I have a habit of hitting ATK every time I turn the phone off, so that's exactly what I did.
No wifi, bluetooth, GPS were on.
I wake up this morning to the phone being completely dead...I start it up and it has 1% battery left.

Also, is "Wifi Sharing" aka tethering? This is weird because I have never even configured this feature, let alone turn it on and do not want it on for risk of being charged!
Thanks,
Elliott
What firmware version? (settings > about phone, post android version, Kernel version and build number)
As in the older versions the Wi-Fi sharing feature has a habit of sucking battery.
Also you shouldn't use ATK's, they do more harm than good on modern high memory devices.
As @veyka says, avoid using ATK, download BetterBatteryStats and look for any wakelocks that are keeping the phone awake during the night.
Thanks guys I'll stop using it.
It's 2.3.3

There hasn't been any updates for my phone yet...(Bell) and I don't plan on putting a different ROM on my phone.
Is there another app like BetterBatteryStats? I don't really buy apps.

See the link in my sig for BBS, theres an XDA edition.
No its not on, its just running in the background draining battery (Bug in the program in older 2.3.3 roms). Or at least it looks like it is. Its a part of the rom, it comes on all SGS2 phones as standard, you shouldn't be being charged.
The only way to freeze/stop the app is to root, and if you want todo that or not is upto you. But use BBS to check first.
Thanks I will use it tonight to see. Are there any special settings I need to set to get it to read what's causing the drain?
This is the first time this has happened so obviously something must have changed which caused a major battery drain.

Sometimes the fuel gauge chip gets confused after doing something that uses a lot of juice between reboots, like flashing zips (After all battery status is just an estimate), it will correct itself over time, this on the otherhand is drain due to buggy app.
Okay guys here it is:
http://pastebin.com/HU3bys2j
I'm not sure this will be much help to me, though...because battery usage was back to normal today...~70% battery life after sitting the whole night...kind of **** but it is what it is.
First of all update your ROM, you're still using 2.3.3, in some 2.3.3 ROM's Wifi sharing bug was present, update it to 2.3.6, Wifi sharing bug will be gone for sure.
Now about your Wakelocks there is not much there other than some Chat service, in Kernel Wakelocks there is dormancy present, so disable it, disabling Fast Dormancy helped a lot of people, it should help you too.
Swyping from my GT-I9100 via Tt
Thanks.
I'd rather wait for an OTA update or an official update to update my phone...
I also read somewhere that turning fast dormancy off can potentially use more data when using the internet, etc. Is that a load of baloney or not?
when signal is weak, device try to get good signal. I think that is why your bettery has gone.

You may be waiting a LONG time... There is no harm and very little risk using a firmware from Intratech's Official i9100 Firmwares thread. I believe the firmwares in post #2 are from Samsung, and as far as I know the only modification Intratech does is replace the bootloader with one that can be reset using a USB jig.
I also read somewhere that turning fast dormancy off can potentially use more data when using the internet, etc. Is that a load of baloney or not?
Click to expand...
Click to collapse
From what I understand, fast dormancy causes the connection to drop from HSPA/HSPA+ to 3G if you have NOT been using something to keep an active flow of data under a very small amount of time. So in other words, if you're not loading a web page, or streaming music, and data is generally not flowing to your phone, it will drop the connection to 3G in a few seconds. With fast dormancy turned OFF, it will stay with an HSPA/HSPA+ connection for longer.
There are pros and cons to both sides. You might save a little bit of battery with fast dormancy turned on, but I've found it slows down your online experience, as it takes a few seconds for it to negotiate from 3G back to HSPA/HSPA+.
Hope that makes sense.

Kies sucks. You have to wait for Samsung to update their databases to say your phone in your region has an upgrade (I got tired of waiting after 6 months of being on 2.3.3), and they dictate what version you upgrade to; not always to the latest version.
Check out Intratech's thread I linked above. There are instructions in post 1, official firmwares from Samsung in post 2.
I see.
But how do I know which firmware to download? It's all so confusing...
factory reset and monitor apps installed-simplest way to see what's wrong. If that doesn't help, its gotta be your battery. Also, kill wifi sharing if you're rooted.
Hi
Had a similar prob w/batt drain till rooted and install app called autostarts which basically disabled unnecessary apps from restarting.
Hope that helps.

Hm, that's very odd. Could you please post a Screenshot of your BBS? That would be helpful. Normally I'd say it's probably BLN or suspend_backoff, but since you're saying that there aren't any wakelocks, your battery is either really old, or very very poorly calibrated....
Poorly calibrated? I havent checked on that yet.
I also forgot to get a screenshot of BBS. Ill get a screenshot after another charge cycle. But i read somewhere that this devices fuel gauge doesnt need calibration.

In honest terms I have done over a week of research on this. I found out that a load of galaxy s2 users are having horrific battery life (20-30% increase) on ics. And there might be a bug causing it. Personally I wanted to test this out... so I returned to gingerbread, and then ics. By far it was a long shot that gingerbread was better than ics. Don't know whats causing it, and I've asked aj to do a little battery working on his rom. But no avail...

There is no need to calibrate your battery on the i777 as it does nothing.
On to OP's question:
The battery percentage can be deceiving at times. I've noticed that after flashing numerous roms/kernels, my battery % would increase/decrease. This is insane as it should always decrease a bit after flashing. My remedy was to use a kernel that could wipe the fuel gauge (fluxxi or siyah). You can do this by using their respective apps (as you're on the official "leak" customized by AJ, get extweaks once you're on Siyah). After doing that, let the phone naturally die off. Then do a full charge cycle. This helped a lot in having a more accurate reading of my battery % as well as longer battery life (at least from my observation).
Also, are you using the official battery for the i777? If so, how long have you had the device? I've heard that some had to buy a new OEM battery.
Yes I have the original battery. I've realized that a lot of the roms I've used have some kind of battery life problem. Roms like MIUI are rough on battery on my phone. But the best battery life I've ever had was on a CM9 Nightly. Too bad the CM9 camera wasn't too good or I would've stuck with it I think I'll try switching to AOKP and give that another try, even though I've flashed that rom a countless number of tines already.

Most of the Devs recommend 3 cycles of depletion/charge before you even worry about battery life. Plus have you checked to see if you have a roque app chewing up battery?
Yes ive checked that too. I usually dont install many apps to begin with. Ill let the battery deplete 3 times and report back. I would also like to say thanks to everyone for their input.

In the siyah kernal you can delete battery stats if your in cwm I clear that after each flash

In honest terms I have done over a week of research on this. I found out that a load of galaxy s2 users are having horrific battery life (20-30% increase) on ics. And there might be a bug causing it. Personally I wanted to test this out... so I returned to gingerbread, and then ics. By far it was a long shot that gingerbread was better than ics. Don't know whats causing it, and I've asked aj to do a little battery working on his rom. But no avail...

If you have something specific in mind then by all means share it with me.
Unfortunately, you saying "i get bad battery life" is of no help - especially when I am getting VERY good battery life, and so is everyone else who comments about battery life.
To the OP: You might want to reinstall and use the fresh install option. I have never seen Semi use battery in a bad way unless a rogue app was in play.
EDIT: I just noticed that you have checked for wakelocks. In the absence of any wakelocks, you may have a hardware issue. How much screen on time did you have in those 13 hours?

I think I had about 1 hour and 30 minutes or close to 2 hours. If this was a hardware problem how should I handle that? I got the phone in February, I'm not sure if I have warranty now since it has been a few months since I got the phone.
I have siyah kernal and if you boot cwm hit kernal specific items then set the battery to performance that may help. I've NEVER seen a drain as bad as yours. Are you on Wi-Fi? If so a bad wifi network that sends out a lot of un-needed traffic may hurt you.
Kernal specific options -> set battery to 'optomized'
If anything, and sorry if you said this, but go back to bone stock no apps, do it before bed is when I do things like this, let it set if you still see that drain jigg it and return it. Honestly if it is a hardware problem I wouldn't try to mess with it and break it then be sol. Maybe it is the battery go to any att shop and they should flip you a new one for free if you get a cool dude or lady like I usually do. Sorry if my posts waste your time just trying to help

Any help is welcome, and thanks for your time. I think I'll try to wait another few days to see how the battery life is. As of now my battery dropped from 55% to 30% in a little more than an hour. I also didn't wake the device at this time. I hope it's not a hardware problem, I've noticed poor battery life for as long as I've had the phone but it wasn't as bad as it is now. Does anyone know about how the warranty works? I always thought the warranty lasted for 30 days or 3 months or something.

Ok guys. I just woke up and checked my phones battery. It looks pretty good all of a sudden.
How does that look? Just a tiny but of drain but its much better than a 30% drain.

Stock ics gave me horrible battery life. Over 3 hours of wake locks from the system alone. I had only Tapatalk installed. Then again I was only trying it out for fun.

I got an S3 a couple of weeks back.
I've noticed that the battery duration is subpar.
I haven't even rooted the device yet and it doesn't seem to be the same for everyone.
On the pic attached you can see that it has been a few hours since disconnected and it has already consumed almost half of the battery.
I wasn't doing much other than about 20 minutes of web surfing, 3 or 4 texts and about 15 of playing music for my car stereo through the aux. Other than that nothing, no pics, no calls, etc.
I'm on 3G (H,H+) all the time. Do you think that's the issue?

Depends. Please use the dialer code *#0011# (or *#*#0011#*#* on AOSP-based ROM's) and check if the RRC-state goes to "IDLE" when your phone has not transferred any data for some time and HSPA is active.
If not, your carrier probably does not disable Fast Dormancy or you have Fast Dormancy disabled for whatever reason.
Please, if rooted, let Better Battery Stats (free APK here in Xda) record the Wakelocks across several hours and make a screenshot of the Kernel wakelocks and Partial wakelocks.
All I can see from your current screenshot is that you're constantly discharging and probably are on an older firmware (Upgrade!) since it doesn't include the Fix for the cosmetic issue causing the Cell standby being battery drain Nr.1
Are you using Apps like Skype or Facebook? Both are known battery drainers.
Have you been in low-signal or no-signal areas?

Thanks a lot for the reply.
I'm in Mexico and we haven't had the update released here. That's why I haven't upgraded yet.
I'd love to go to CM9 but as it stands I don't want to take risks with the modem, the scene is kind of young still.
I'm not using skype or facebook. I do have them installed but I don't have them running. I actually have sync for FB disable.
I'm very willing to uninstall both if you think it will help.
About RRC-State:
If I'm on wifi it says iddel.
The phone seems to go to HSPA only when downloading something and stays on 3G while idle. While on 3G RCC State reads "FACH".
How can I enable fast dormancy?
By the way, since 12 am today, I have downloaded less than 7MB of data from my mobile network. Anything else has been over wifi.

If it doesn't go down to IDLE then fd is confirmed off or not working. However not all providers support it so it's not that easy.
You can try this, but do a backup of the corresponding files first and of course replace wherever required the values with your provider's:

You don't have to wait, just flash any Rom of your liking, including e.g. Omega ROM. You can flash the CSC back.

The problem is, your phone keeps a full-fledged high-speed data connection open at all times since it or the network is unable to go to Fast Dormancy. Open 3G/HSPA connections drain the battery faster than you can look. Talk about carriers sucking you dry =)

The modem doesn't change when flashing CM9. You should flash the BFLB modem though since otherwise you get issues with voice calling.
Plus, you can always go back to stock by flashing your (or a close) firmware from samfirmware.com through Odin.
I highly recommend trying CM9 =)

Thanks a lot for the help. I don't think I have the data required for doing that mod for fast dormancy. Most likely that is the culprit then...
I was waiting to root and such because of the flash counter but I guess there is no point in waiting. The phone like this actually doesn't do much for me. It's a pain to be concerned about enough power and I totally need to have the data on all the time (critical work emails). I always carry a backup iPhone 4 in case I have problems with my main android but I rather just use Android all the time (it rocks!).
I guess I'm down for CM9. Just one more question, my firmware doesn't appear as it is on samfirmware. How can I find out which one is closer to the one I got right now?
Edit:
Actually I found it. It wasn't there before but it is now. It might be newer to what I got right now.
I rooted my device and made a nandroid.
Just for research, instead of putting a new ROM I'll try to do a bbs log of my phone as it is to try to find out the reason for the drain although it might very well be the carrier config.
Trying to figure out why my battery life is relatively crappy (usually averaging >8% drain/hour under typical use), even when I'm not using the device.
Anyone on Marshmallow (Android 6.0) able to experience the 'Deep Sleep' processor state? I cannot, and I'm trying to determine if there's a particular app (or more) that's causing wakelocks, or if this is just something I need to live with. Without root, it's nearly impossible to tell what's causing wakelocks directly.
If it is an app, I can try to find it, but I really don't want to uninstall and then selectively re-install hundreds of apps only to find out that the device doesn't sleep anyway (if rooted, I could freeze all user apps and then slowly unfreeze, but that's not an option without root).
To be clear, I'm NOT talking about the Doze feature that comes with Android 6.0. I'm talking about the Deep Sleep processor state that is below the low (384Mhz) processor state.
On all my other previous devices, I've achieved this state - granted, most of these were rooted, and I had custom ROMS and custom governors. This device seems to use the Interactive Governor. Maybe that governor doesn't sleep at all?
Anyway, if one or more of you confirm that you're achieving this state, then I'll burn some more time on it, otherwise....
thanks!

I'm getting deep sleep. The battery drain could just be the phone itself. My battery life on the v10 is also pretty bad.

Thank you. Here's mine. Notice zero deep sleep in many, many hours. I feel like this is something that has changed.

I guess I'll (reluctantly) do a factory reset and add my apps back. Thanks.

Yes, Android 6. Unfortunately wake lock info is all but useless without root, unless the offender is really obvious.
I uninstalled almost 130 apps, and this far have reinstalled a little over half. The good news is that she's sleeping again. The bad news is that I'm still not sure which app was causing the issue.

Be thankful you aren't me right now. I just rooted and put xposed on my phone and my battery is draining from 100% to dead in about 2hours 45minutes...with no screen on time. Granted I'm using wifi tether but still that isn't good, nor normal. When I'm using the phone it's dying at an extreme rate; Like phones from 4 and 5 years ago would. Battery usage says android system is causing most of the drain. Something is seriously wrong ><

That's just wrong. Did you change out the ROM for a custom one, or just root? You might want to try a full wipe and start over if you haven't already.
Truthfully, a couple months ago I debated not taking the MM upgrade so that I could root 5.1.x. - ostensibly to give me more control over battery-related information and activities. I took the upgrade, and - now that my device is sleeping again - I'm kinda glad I did - Android's getting better at controlling rogue apps and with other battery saving methods (e.g., Doze mode). I guess what I'm saying is that if you can't fix your massive drain issue, you could always unroot and take the upgrade ...

I got it sorted. Back to normal battery life.
I was actually on MM for a while but I had to get another phone because my old one started having some screen issues and the one they sent me had 5.1.1 on it so I decided to go ahead and not upgrade this time so I could root and have xposed. For now I'm sticking with 5.1.1 Now that I have everything setup I'm getting great battery life. I got over 4 hours of SOT time yesterday and today 6/6/2016 I got over 3 hours of SOT and 2 hours of tethering and about 10 hours overall before having to plug in.
Once I wiped after OTA my battery was WAY better.
I'm having a serious battery drain problem that i cannot figure out. I'm on mm 6.0 and the phone won't doze nor deep sleep. I did a factory reset several times and it's still eating battery in a ridiculous manner. Any help is appreciated.

Did you try it after the factory reset but before adding back your apps?
