I have been experiencing this screen flickering for about a month now, my S2 start to flicker, lost the signal and shuts down. At first I knew(or atleast tought) it was the battery because it was thicker, so I bought a new one but it keeps doing the same thing, what else can I do? Any suggestions please?
PS: Sorry about a new thread about this, but i didn't found one that says that the battery was already replaced by a new one.
Thank you
Are you rooted?
Cause then it could be a ROM bug or something.
If it's not roted, take it to service. (you can go to service with rooted phone to but keep in mind --> root = void warranty)
Cheers.

Device Info would be great.
It's either the kernel or hardware, but i'm just guessin cuz I dunno what ROM/Kernel you're on. Why? No device Info supplied.

So you flashed neatrom recently, same issues?
We are talking genuine samsung battery right? no cheap-chinese crap from e-bay?
You could rule out kernel with a deep clean, nuke script will do that for you.
If that don't work, you're looking at hardware. Warranty voided?

Yup, been using neatrom for about a week now, I dont remember which rom i had when it started flickering. But before neatrom I was running Omega 19. And yes, the battery is genuine samsung, and its not bulged.
I deleted the battery stats a few times, calibrated with battery calibration a few times, And recently used Ibroid Kernel Cleaner because i had a bootloop, does that one do the same as nuke script? I'll try it anyway
I believe my warranty has expired, it last for one year (Digicel Aruba)
Check again for the warranty thing.
Nuke script deep cleans the device so previous ROMs leftovers won't cause any issue.
How were your stock trips? Ever been to JB leak land?
Feel free to try it out.
You really need to rule out all software related before you start thinking hardware issue.

I will try the nuke script than, I recall I was on the leaked xxlsj when it happened, but then again my battery was bulged.
But why use a leaked version if there is already the official xxls8?
Ill try the stock version anyway, do you think it will change any thing if I flash the stock version and root it, I mean, would it still be stock?
Thanks for your help, really appreciated

Exactly the same problem I was encountering on my SGS2. I am on OMEGA 19.2 never been used leaked version using PhilZ then Siyah but remains the same. I was thinking as well that my battery was damage already, I also did so test I tried to play games with charger on, I finished round without flickering then I tried playing again with 90% batt and after a moment it flickered and suddenly blackout not only that I experienced it as well while flashing so now I flash with charger on. What is that nuke anyway? Can anyone give me the link?. It came to my conclusion that I had damage battery but seeing this post is exactly the same dilemma I am experiencing. Attached is the logcat from bbs. And screenshot of in battery graph you can see the cut, it is the time when it flickers and blackout.

I hope someone will look unto this whether its a hardware or kernel/rom issue. I wonder what causes this one.
For starters you need to try another battery.
You're device is also awake while the screen is off so you got a drainer over there.
Search for nuke script and you'll get to the thread.
If you guys get that flickery screen only when % drops, then you might not have a hardware problem.
Here at xda we tend to rule out all software before we start thinking hardware.

You nuked it, flashed custom, checked the battery, swap the battery (all genuine) so I guess yes...it's hardware.

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

@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:

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?

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

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,

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.

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.

Mine gets a little hot at times too. I just pulled mine out of my pocket to show a friend and my screen was on and it was pretty warm, more than usual.
yeaa it gets really hot. i can't even play any hd games. the phone might over heat and crash
I had 14 hours of use today and over 4 hours screen on time. I think the higjest one got was 95 deg
I have the extended battery if that matters
Yeah, she gets a little warm. Anecdotal evidence says that the phones that get way hot (130-150 during games, 120 ish during regular use) have a hardware problem... I have read from a lot of people who have been that hot and say the trade-in was better.
Also, the extended seems to dissipate the heat better.
As for me, I didn't have much of an issue until after the first OTA. Now I top out around 125 when playing heavy games or surfing hard on 4G. Not happy about that, but I don't think it's hardware in my case. I need to get an extended anyway....
Its because of a CPU issue where the CPU runs at the highest clock speed instead of scaling like it should while the screen is on. I have this problem as well and my battery is absolute **** now :|

But I did have almost 5 hours screen on time :-\ didn't feel that hot. Really like having ics but that's getting pretty warm
i am using "easy battery" to help me keep my battery life and kinda keep it cooler. i recommend to return to stock os and wait until the official upgrades are given out.
When I first got this phone it actually ran hot, so hot that I can actually feel the heat on my leg when I put it in my pocket.
When I upgraded to the current leaked RUU, the heat problems went away.
I have zero heat issues on my Rezound, I still haven't gotten the new leak yet, waiting for a ROM that makes me really want to do it.

I have the leak, just deciding which ROM to go with. Is there currently not a ROM that you are satisfied with?
i read in another thread that there is no way to get the official update after flashing the leak. soo bad luck guys

Everyone will install the ota the same way the leak was installed. The ota will include new radios and a new boot loader version. They always have. Easy.

correct me if im wrong.
i thought u would not be able to get your phone back to stock after flashing the leak . and the official update requires ur phone to be stock. something like that
" correct me if im wrong"
.........................................
maybe the official update will fix the problem
You could run the RUU again and you would be back to bone stock, albeit a leaked "official" stock, but still stock. You would have the stock recovery and be locked again.

Its because of a CPU issue where the CPU runs at the highest clock speed instead of scaling like it should while the screen is on. I have this problem as well and my battery is absolute **** now :|

I don't think it's the CPU. Same cpu problems in the last couple of leaks and phone is running a little warmer on current leak. I think the radios are cranked up, pulling more power. My phone only gets hot when on 4G.

Hey guys, I know most of you have seen enough posts about the battery but I need some help on understanding why my phones battery dies over night when it was at 58% when I put the phone aside. Here's a screenshot

I've checked BBS and it doesn't show anything obvious. No wake locks and no processes draining battery. I did some research and read that the Google apps and services are hard on battery. I'm running the latest stock firmware with AJ_Newkirk's kernel. Is there anything I could do to have 1% idle drain like most other people? I might change my kernel to see if this a kernel problem.

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.

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.

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.

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.
