Strange battery issue - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hello all. I was looking for some possible cause/solutions to a strange battery issue I am having on my skyrocket. I've been runing with no issues until yesterday. All of a sudden my battery drains CRAZY FAST. It will go from 100% to 30-40% in a matter of an hour. This is even with it locked and sitting on my desk,
I have auto sync turned off...
I have not installed anything in probably 3 days and the battery usage screen looks as normal as it ever has.
My question is, would it help if I booted to recovery and the reset the battery option? Should I make sure it's 100% charged before doing that?

You can wipe the battery stats, but it probably won't help with the discharge problems
What's draining it so bad in the battery monitor? Maybe a data connection problem? I've had draining issues on the ICS battery, maybe something similar is happening to you. Might check your APN settings/turn off data and see what happens

People say that Wipe Battery Stats does absolutely nothing on the Skyrocket.
There is a way to calibrate your battery using Root Explorer to delete the file with the battery stats (the file regenerates on reboot), but I can't seem to find the how-to thread on that right now (and don't have time to search). At any rate it does involve fully charging it with the phone on, then fully charging it with the phone off, and then deleting the file.
Maybe someone else can better explain what I'm getting at..
Also, you might want to try Juice Defender from the Market (or Play Store if you prefer to call it that). It's a great app that can help you monitor and conserve your battery usage.

Thanks for the suggestions...I forgot about that other battery reset method with the file. Also, I had forgotten to mention that I am already using juice defender. I uninstalled it this morning and reinstalled it just to see if that helped.
Thanks again for the responses!

same problem here

Fyi...it was Facebook. Nor sure what changed but I uninstalled it and everything was back to normal. I even had the sync and notifications off. Will reinstall tonight ans see what happens.

Strange battery issue...

So I get home from work this morning, pull my Inspire out of my pocket, and it's dead; no lock screen when I push the top button, nothing but black screen. Kinda strange, since I had just been using the phone a few minutes before while I ate breakfast before a 5 min drive home; it still had 22% charge right before I left. I put it on the charger.... nothing. Black screen, no amber light. I let it sit for about 15 minutes, still nothing. I drop it back in my pocket and put my shoes back on, about to head back out to the AT&T Store to exchange it, when I hear R2D2 in my pocket (I'm running LeeDoids ROM). Sure enough, it's booting.... wtf?
It's plugged up and charging right now, which kinda sucks in a way, because I was looking forward to exchanging it for a new one; my battery life sucks in it, worse than it should as far as I can tell with reading up on all the threads here. I'm trying to be very conservative with the settings lately in an effort to stretch battery life, with limited results. I've turned off auto-sync, installed Juice Defender, I turn off the wifi & bluetooth while I'm at work, running the display at 40%, but I'm still running the battery down damn quick if I actually use the device. Earlier this week, it ran itself down to <15% battery in just a few hours just sitting in my pocket, and I wasn't even using it; the only thing I could figure was that the auto-sync was on at the time and it had connection problems where I was in the hospital, making the phone burn up the battery trying to get a connection. When I looked at my battery info, the overwhelming majority of the battery use was for Android System. Now with auto-sync off, the display eats about twice as much of the battery as the system does.
I'm thinking of taking it back anyway if it acts up again. Has anyone else had one that just simply ate battery at a huge rate? LeeDroids ROM has a reputation of being pretty easy on the battery, but right now I'd have to say I'm worse on the battery than I was when it was stock. I'll probably try out a different ROM later today, just to check things.

Fully charge the battery to 100% then wipe battery stats in CMR. Hopefully that will help you out.

Does wiping stats improve battery life, or just give you accurate future stats?
Sent from my Inspire 4G using XDA Premium App
Improves battery life and makes it more accurate. I would try downloading the Rom and make sure you flash everything. Also make sure your not over clocked.

I'm gonna reflash the ROM and see how it works before I try another one. I'll make sure I'm not overclocked too much, but others with LeeDroids ROM are getting good battery life with overclocking. The two big symptoms I'm looking at right now are heavier than expected battery drain, and the total lock up it had where it wouldn't even show a charging light.

What is CMR? How do you wipe stats out? I looked for it in settings & couldn't find.

Hey Smitty, I know it's been over a week but have you had better luck with your battery usage?
Also with regards to your unresponsive power issue. Given the size of this handset I've found it difficult to keep it in a pocket. I'd bet that the battery door wasn't connected good or got separated slightly in your pocket, probably getting in & out of your car. It doesn't look like it would take much to separate the contacts in there leaving you with what seemed like a dead phone.
I did a complete wipe and ROM switch... installed dilligafs, and I had much better performance. Using MIUI now, still getting good battery performance. I might have had a bad ROM install before or maybe I left a location using app running. As far as the strange black screen issue, I never did figure out what that was about; the phone was in a Otterbox case, and the battery cover was on tight, so I don't know what happened. It hasn't repeated itself, at least.
One thing I miss about the iPhone was the ability to set up a periodic sync, instead of an auto-sync like we have on Android. Auto-sync is either on or off, and when it's off I can't figure out how to get gmail to sync any way other than a manual sync. I could easily live with syncing every 15 or even 30 mins, and I'm sure it would give me much better battery life. Juice Defender claims to do this for you, but it doesn't work in Gingerbread it seems.

[Q] is rooting always like this

Maybe this is due to my lack of experience, but maybe not. It seems like every time I put a new ROM on my phone it goes to hell in about a month. I'm not a technician but I can follow directions for installation, patches, etc. So far I have had 0 long term success in installing a ROM that ends up being any better than stock after 30-60 days.
For example, I've had issues with battery drain, random booting while the phone is powered off, redraw issues, serious lag, data connectivity issues, and a few other things. It seems like its always something.
The only phones I've toyed with are my old Eris and my Charge. Is this a phone issue, noob issue, or is this par for the course? If it is par I'll end up back at stock and have mediocre performance rather than have a buzz saw that ends up needing constant tweaking and maintenance.
Btw this isn't a knock on developers. I appreciate them sharing all their hard work. I just want to know if everybody else goes through this or am I holding a bag of stupid.
Just rooting does nothing more than give you superuser access. It doesn't even do anything that uses the root specifically. Different roms do different things, but nothing to use battery...mostly they take things out rather than put things in.
Best thing to do is look at BetterBatteryStats and track partial wakelocks. That will tell you what is waking up your system and if there's anything spiking it, you can deal with it. Most of what really drains battery on this phone, other than bad apps, is somewhat random, and it will affect non-rooted phones just as much as rooted.
Must be something you did, picking a good rom make a big different. In my case. I flashed tweakstock to my daughter's phone since the first day it released (with tweakstock kernel), and never, I repeat never have any issue, when tweakstock 1.4 released, this is the second time I touch her phone and up until now she hasn't have any issue. If you use eclipse rom, PBJ kernel, Imonsey kernel, you're going to have issue. They are not bad roms or kernels, but they do have bugs. This is my experience.
Yeah, I think it's you. On stock, I'll be lucky to get 12 hours usage in a low signal environment. On a custom ROM, with custom kernel, I'll make it through the day. Of course, I've had a couple of random total crashes where I had to go at it again, but I deal with it.
PROTIP: the Facebook app needs to be told to stfu constantly. I would get an app like System so you can kill it easily-it still stays in RAM and in wakelock, taking clock cycles, even if you close it by backing out. I found that this was one of the best battery savers.

Yes, I agreed with kvswim, Facebook is a big battery drainer, I ended up using the browser for facebook, it's not as nice as the FB app, but once you get a hang of it. It's fine. I suggest if you want trouble free, ODIN pit file and original factory image, then upgrade to tweakstock with tweakstock kernel, then install Go launcher for smoothness. To save battery even more install battery saver by Antutu.(keep all default settings, don't play with it). You will see big improvement with both battery and smooth trouble free phone.

you really find a battery saver to be helpful. Every time i try one it ends up costing me more battery life than it saves.
As for the phone issues. Are you wiping data, cache, and dalvik before you flash? Not doing so can really muck things up. And a lot of times its just an annoying app that sucks up all ur juice, ie words with friends and facebook. I use them alot so I deal, but u can definitely tell the difference when u dont have those apps installed.
No i dont think its u...i have problems also.i jus made a post about my home/hard key...its always seems to b something after the next.but it looks like people find ways to deal and eventually conquer.also i appreciate wat the developers do.its alot of work and headaches.on top of posting and replying to many many people.its the roms that cause problems...constant tweaking and toying around...alot of times things jus need to b debugged a little it seems.but its all in the nature of what were all doing here.good luck to u

Hey. how about give the "battery saver" app by Antutu a try. This is one of the kind. It does not kill processes like others. It actually readjust cpu frequency during usage and put your phone in heavy deep sleep, after installed, let it run for 2 days, you will notice at least 3-4 hrs more during usage and 10+ if you let your phone sleep. I have test this app with wifi,4g,gps on 24/7 and I still have good battery life.
I downloaded betterbatterysaver to check my stats. Now to figure out how to read the data. Any suggestions? I've searched Google and it seems to be a mystery for many. It appears that Dolphin HD is using most, but I kill the program when I'm done???? I switched to mini and froze HD to troubleshooting. I only use FB browser too. I ditched the app long time ago.
Before I flash I wipe dalvik cache, data, and then wipe it again. I follow directions closely since I can't figure my way out if something goes wrong. I'm running tweakstock's latest right now and I'm really enjoying it. Very stable and snappy. However, the battery problem is killing the experience. It drained fro. 69% to dead in 6 hours overnight! Switched from 1.1 because the phone got very laggy and the hand off between 3-4g was getting dropped and I was losing data connection.
I will try the battery saver app. Just got battery calibrated and still not any better. My need to have a phone that doesn't suck will keep me playing with this thing until I get it right. My Charge is used so much it's like my third hand.

Did you try to disable(freeze) SDM app and also Google service? May need to backup all your apps and do a factory/data reset, If not help, possible to re ODIN factory image (see pos # 5) since you have data drop issue. Some thing is mess up in your OS.
For betterbatterystats look at wakelock and see what process used the most.
If it died overnight then something is definitely eating your battery. Are you in a low signal environment? Go to settings, about phone, then battery usage. If anything besides display is taking more than around 5-10% (can be more if you use it a lot) then that's your main problem. If your cell standby is more than 25% it's the low signal that's killing the battery.

Data is up and running smooth after flashing newest tweakstock. My home has a strong signal and my bedroom is sometimes 4G so I don't believe the signal was low, unless the transition between radios killed it. However, it wasn't a problem 3 weeks ago.
I did freeze SDM and noticed some improvement. Buhohitr, did you mean freeze Google services framework?
Battery usage seems to be normal for now. I am noticing Dolphin is no Singer sucking down 35% or more since I switched to Mini. It doesn't even show up on the list.
I'll see how it goes today and report back on wakelocks. If it doesn't get any Beyer ima Odin to stock and root/flash tweakstock again.
Also, the battery doesn't drain unusually fast wile in use, browsing, music, etc. But when it sits it drains at 3-4% an hour.
I would try manually calibrating your battery. It really worked for me. On average I get about 18-19 hours on one charge with medium to heavy data usage throughout the day. There is a thread in the General section.. I'll post a link in a little bit.

Wiping battery stats is a complete placebo. All the battery stats stores is the state of apps as related to various things that affect battery life (like display on time, screen brightness over time, and wakelock states). It does nothing that will actually affect your battery life one iota. It is actually cleared every time you charge your battery to 100%, so manually wiping it is completely pointless.

I'm well aware of the post of Dianne Hackborn debunking the myth of wiping the battery stats; however, if you actually read the post on the steps to calibrating your battery, it's not just wiping your battery stats. There's actually a few more steps involved. You're right though, if you just wipe the battery stats and expect better battery life you're just wasting your time.

To disable Google Service, go to settings -> location&security and uncheck Google service. Do not freeze Google framework. Also seems like your phone is not in deep sleep, please install "battery saver" by Antutu and let it works for 24 hrs, you should see huge different when your phone is sleeping. BTW what kernel are you using? If you're using PBJ kernel you can install "CPU tuner" to further keep your phone in deep sleep. I'm talking about 1% for 3 hrs sleeping.
I'm curious as to what Battery Saver actually does. The app's market page doesn't say. I'd be curious if it would interfere with my IMAP push email or SetCPU's overclock settings.

I've done that and never seen an actual difference. Like I said before, I have no reason to believe that any of it is anything other than placebo. My normal daily variability in use is more than enough to account for any perceived differences. On top of it all, bump charging is not good for a Li-Ion battery, so if anything, those instructions are a good example of how to lose long-term battery life for short term gain.

Personally, I believe that most of the time the procedure does nothing. I think there are times, though, that corrupt data gets into the battery stats. For instance, I had an app lock up my phone and force a hard boot. When the phone came back up, it showed 22% more battery than it had previously. I believe that bad data such as this can over time affect how Android reads your battery life. In that instance, I believe clearing battery stats would help. I don't think doing it just because a new ROM was flashed actually does anything, though.

Battery drain after rooting

I rooted my Sensation 4G for the first time yesterday, and was pretty happy with how smoothly everything went. However, I noticed during normal use today that the battery was being drained faster than usual. It dropped by about %20 within a two hour period - much faster use than during pre-root. I checked things that might have been draining it. But I found nothing new that could've been considered a possible culprit. I'm running the stock rom with Go Launcher EX. Has anyone else experienced this phenomenon after rooting?
Not without flashing a custom rom, and even that's a rarity. Rooting in general does not cause much extra to be run, so battery is virtually unaffected. Try fully discharging the battery and charging it back up to 100% without interruptions during the recharge. That usually clears up battery issues.
A better idea is to completely charge the battery until it is 100% and the led light turns green. Then while the phone is still plugged in go to your recovery menu and wipe the battery stats. This is not a recommended process, its a REQUIRED process every time you switch roms. That should fix the battery issues that you are having.
Thanks, I'll give that a try when this drains out. I also noticed that more RAM is being used now after rooting, which looks to be the result of too many apps opening in the background. It's strange that this didn't happen before either. I'm hoping something didn't go wrong in the rooting process that caused this.

Are you using many apps that require root permission? And the battery stats is only reccomended, some people say its a myth and don't bother, but do it once for every new rom. And give it a few full discharge and recharge cycles before deciding the battery drain is high.

I'm only running BatteryCalibration and Titanium Backup that need root permissions. I'm just seeing more regular apps running now than before. And I've been checking app activity through the Go TaskManager Widget if that means anything. I'll take the advice and calibrate the battery after it's at %100 and give it some time, although I didn't change ROMs yet. Would flashing a ROM and then calibrating have any possible effect on this?

Task managers tend to cause more harm than good, they're okay to monitor but killing apps all the time drains battery. As far as ram usage goes, a good custom rom will work wonders, and depending on which one you pick, the battery should improve too, but as far as calibrating goes its the same on any rom. Most recomend wipes.
When charging to 100% I highly reccomend using an app called current widget, because the battery is out of calibration it won't show an accurate full battery if it won't show an accurate draining one. So use current widget and charge overnight, or as long as you can, leave the phone locked as much as possible and check the mA value every now and then, and even if the phone says 100% wait til the mA reads close to 0, mine usually doesn't show less than 15mA after an overnight charge. Then wipe stats.
Sorry for the essay but I've read a lot about this and current widget seems to be the best tool I've found.

[FIX] For Battery Reporting and Draining Issues

This will likely fix any battery reporting problems that occur and should be done after installing a rom, or whenever you think it is needed. It will not actually make your battery life better. It may seem like it as before resetting it may have said 1% remaining when it was really only half dead
NOTE: you must be rooted, which if you are on this forum you almost definitely are
1. fully charge battery and leave plugged in. click calibrate in this app or manually delete the file yourself: https://play.google.com/store/apps/...yLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
2. Unplug and let the phone die with normal use
3. charge it fully without a break.
4. done. thank me if it helps
This resets the battery stats. It was noted awhile back from someone at Google that this doesn't help with the battery. I used to use this app all the time after a flash and then a couple of months back i stopped using it and really haven't noticed a difference. I'm not trying to ruin your moment of helpfulness but I really don't think it helps with the battery.

No problem. You are right. This will not help if your battery is actually draining. It only changes what android thinks your battery level is at. this can get screwed up after a flash, depending on many factors of the rom. It also is different with every device. What it helps with is when your stats are off. for example temple run takes 60% of your battery when you play for 5 minutes and you know it isn't running, or it drains fast to 1% then lasts another 6 hours. So if you are noticing poor battery life, make sure it is really bad, not just reported wrong. I will edit the OP to say this more clear.
2. Unplug and let the phone die with normal use
3. charge it fully without a break.

This is what really fixes the issue. Clearing battery stats with an app or through cwm is redundant.
I don't recommend discharging all the way though
I thought fully charging the battery reset the stats. No?

I think partially, but I know for a fact this process works great and isn't that hard. It resets things better from my understanding because it totally wipes stats instead of just re-calibrating some things

Battery drain

My desire s battery drops from 100% to ~15% after about an hour of surfing with edge mobile network.(with different roms) And my friend tell me that this is unusual. I have tried calibrate the battery with the battery calibrate app and it didn't help . It's there anyway to solve this such as flashing baseband?
Thanks for helping.

first open battery usage and investigate which app eat a lot of power.
sometimes just restart the phone will clear out the issue.
The app which eat many power is the browser but I have tried other browsers too but same problem happened.
I have restarted and flashed tons of times and ROMs but same happened.

- which rom are you using? official or custom ?
- try to restart phone, donot open any browser and see if the battery still drain?
I tried cm stable, miui stable , HTC sense ROMs. It only drain when I surf with my edge mobile network. If I use WiFi its normally draining , about two to three hours.

with the same radio? or different?
if the same radio, try to flash another one
if problem with different radio, may be bad coverage in your location?
Try to move to another place with good coverage and give it a try
As i remember i never flashed the radio. Can u suggest which radio should i use?
Does baseband affect the battery life? If yes l, which baseband should I flash? Thx

Can we use that if i'm using hboot 2.00.002?
- firstly check to see what radio version are you using now?
- make sure your phone was rooted when calibrate battery. Is it rooted?
serious battery problem
OK, I have a serious problem. I updated official RUU, and my phone is running smooth. Battery lasts 1-2 days, everything is working fine. But last night battery was on 17% and I put it to charge at 12pm, woke up at 6am and it was on 33%. I'm charging it right now and it's up to 41% then drops to 39% and so on. Tried another charger - same thing. It won't charge! No new apps, no new settings, battery stats shows the same power use,.... Battery health is good, Auto sync is off,.... I have Go Power Master, Juice Defender, shows no problems. 3G is off, it's on GSM only, Wi-Fi is off, GPS is off and so on, my phone is fully optimised and this happened last night. I charged it while off and now it's on 37%! So I guess it's not a software issue. Anybody has an answer or a clue what could be the problem, please? Is my battery dead (year of use)? Thanks in advance.
try to restart your phone?
Tried that. I'm currently charging it power off, turned it on and it's still draining. While it's off!
i guess it's battery problem. Borrow another battery from your friend and try again.
Well, it was a strange thing... I've noticed that GO Power Master is killing like 25 apps and prolonging time for some 2 and a half hours when you hit optimise button every 2 minutes. So some apps are running in the back and draining the battery. So I uninstalled some of them (clock widget, Noom, Zoner antivirus,...) and restarted phone and by the end of the day it was all stabilised like before. I don't know what happened. I'm still testing it but I've managed to charge it to 100% and there was no drain over night. We'll see.

maybe you should look at this man..http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
Noom
I have a S2 and every day, at 20:00 the phone starts a process and gets very hot and also drains the battery.
I discover that if I freeze the Noom app, it doesn't happen.
So, I blame noom for your draining issues and mine.
Does anybody else having this problem?
Regards
I didn't had a problem since uninstall, but it happened again later, I think it was from Firefox. While it was on charger, I got popup note saying something like "phone is using more than current can deliver, try to kill some apps or turn phone off while charging." First time I see that note. Probably because it was on Sense, not on launcher. I've noticed that Firefox is using a lot of memory, uninstalled it and it was all normal like before.

I had this problem, but svery time it was solved with rebooting. It showed normal percentage. I think, you just need to reboot device sometimes, may be once in two days. I suppose to think the couse of ghis problem is a kernel) it can be engaged with not an exact process, so battery drains. Try to change kernel, or rom, or battery)
