[Q] Blazer ROM- Battery Issues - Samsung Epic 4G Touch

So I rooted my phone and flashed the Blazer ROM. Everything flashed well and I am loving the look of this ROM. My only issue is that now my battery is draining very fast. It seems to be going down faster than before the flash. I tried calibrating the battery with one of the marketplace apps, but it hasn't done much. One of the main reasons for flashing was to improve the battery life. I am looking for any suggestions on what I can do? Is there any point in trying to re-flash the rom? Any help will be appreciated.
Thank you in advance!

Give it a few charging cycles for everything to settle in....also download better battery stats and check for possible wakelocks
sent from the near past

I had the same problem with this version of Blazer Rom. After my 4th charging cycle I had to get off it. I couldn't get a whole day use. For some reason battery drained hella fast. I'm back on stock rooted now. No rom has given me better battery life than when I'm on the stock one so far. I usually give the rom about 4/5 days to see any improvements. If too many bugs or battery drain I'll get off it sooner than that.

OK thanks! I guess I will try and give it another couple of days and see if it improves. If not I'll consider switching ROMs. Sorry but what is a wakelock? I'm still pretty new with all of this.

had same issue i just flashed rom three times and since then ive been getting a good 16 to 20 hours on one charge.

had the same issue, i was at work and charged my phone, one our latter my battery was down 20 percent went back to stock root.
Im also curious, what's wakelock?

wakelock is a term meaning an app I going rogue keeping your kernel awake. if you use bettery battery stats and cpu spy you can see what keeps waking your phone up when its supposed to be in a deep sleep. btw when charging it doesn't go into deep sleep. so it may give you a weird result if you check after a charge. also do not spend any money on battery calibration apps. every app I have come across tries to calibrate by deleting battery stats. which has been proven to do nothing. just a heads up dude.

A kernel mechanism for Android power management. When a thread holds a wakelock, the kernel will refrain from entering a low-power state.
Basically, an app or process is not letting your phone sleep. Free app betterbatterystats can help you identify any rogue apps

Thanks for that suggestion! I shall install betterbatterystats and cpu spy and see what happens to my phone as i let it set over night. I've seen it drop by almost 20% in battery life overnight for some reason (~8hours)...which I find to be unacceptable.

[Q] Synergy Battery life and App issues

Hey folks!
I have the EVO 004 Supersonic. I love flashing my Android, and do it constantly. I am having issues with Synergy RC1 that just went live. My battery is draining fast, and I mean in an hour maybe two, I have to charge it. That is just being on idle, not being used. Drains much faster if I use it. I flashed back to my original image (stock) and the battery lasts longer. So I flashed Mik, and it lasted longer and I flashed CyanogenMod and that sucker lasted longer, but I LOVE the way Syngery looks and flows. But I cannot get the battery to last longer. So I thought maybe apps were running that are not supposed to, so I use my favorite app killer and the apps keep popping up, they are driving me nuts. Why the hell are they restarting? I want them stopped and NOT to reactivate. Is this an issue with anyone else, because I really do not want to get rid of this ROM. Also, yes, I cleared the Battery stats as well. Still fast drain.
Oh, one more thing, I cannot OVERCLOCK the damn thing either. So, those are my issues, cannot get apps to stay shut off (force close even), Battery is dying super fast and cannot get it to stay charged longer than two ours. Oh, and I already checked my battery with Sprint, battery is good, and they even gave me a SECOND one, and it still drains fast. Please advise.
Thanks for listening folks, and I appreciate any help. I love this site and has helped me NUMEROUS times, but I finally had post my own specific issue as I have never dealt with this before nor found anything that can help.

jeez...dead in 2 hours...and being idle?! that sux. i was running Synergy for a while and didnt have THAT bad of battery life (i maybe had 7-8 hrs before it needed to be charged again)
and of course you cant overclock yet...the kernel doesnt support it! it's still the stock kernel that came with the OTA...HTC still hasn't released the source code for the kernel so no custom "gingersense" kernels for us just yet (i.e. no HAVS, sbc, overclocking, etc.)
try some of the battery saving tips that Myn links to in the 2nd post of the Synergy thread...maybe that will help
question for you: why are you using an app/task killer!?!?!?! Android has one built in already [MENU >> SETTINGS >> APPLICATIONS >> RUNNING SERVICES (or MANAGE APPLICATIONS)] that could also be a reason your battery life is crappy (i really hate task killers so that last line might be biased lol but seriously...android does have it built it)

First, Synergy runs on HTCs stock kernel, they havent released the source code for the kernel yet, so there are no custom kernels for any evo 2.3 rom, so you cant overclock, or get the awesome battery life we usually get from custom kernels.
Now the battery draining is usually the radios. Right now I have wakelock on my phone running synergy, but I dont wanna mess with my radios, you would have to try different radio/pri combos until you find the right combo.

I use task killers because I can kill all tasks at once instead of individually. I would like to be able to close apps I am not using as well. But they keep popping up. I know now the overclock does not work with gingerbread, but man, I got a lot of misinformation.
I appreciate your help, I will try the battery saving tips, but if it is about letting the phone die, erasing battery logs and then charging it and then making the green light stay on when first plugged in and other stuff like that, I have tried it to no avail. I just flashed another ROM and the battery is FINE! It is so damn frustrating. I see others with great battery life. I just cannot get mine to do it.

Well, you guys probably will not believe this, but I got my battery to last a looooong time! I was messing with my battery options and decided to turn OFF the battery saving option it gives (enable power saver). I rebooted the phone charged it fully and then took it off the charger, BAM! Being FULLY charged it went down one percent after being on for 40 minutes. That is much better than I was getting on my stock and other roms. I just love this dang rom. Now, if I could only overclock the darn thing. So I have had the EVO on for 2 hours and 10mins and the battery says 97%, sweet. Anywho, battery issue is solved, loved it. Has this been mentioned before? Turning off the battery saver to save on battery? LOL. It probably has and I must have been to frustrated to absorb that info. Thanks for your help!
Battery saver...
I, too, was having draining issues on my Synergy-ROMed Evo. I could WATCH the battery drain. But I turned off the "battery saver" in power prefs and it's HOLDING STEADY! I'll report back if this doesn't turn out to be the cure I was hoping for, but it's definitely worth a try.
Now if I could just get this GPS to stop rebooting my phone...

[Q] Battery Draining at 10%/hr

Recently purchased the T-Mobile Samsung Galaxy S2 and I flashed Beastmod v4.2 onto it. I'm experiencing a lot of battery drain, approximately 10% an hour with very minimal usage. I flashed the same ROM onto an identical SGS2 and the batterylife on that one is great. I've tried reflashing Beastmod but still getting the same issues. Anyone knows whats going on or how to resolve this?
How are you flashing it? Wipe everything and fix permissions?
Sent from my SGH-T989
I flashed it following the directions on the Beastmod thread in development.
1. Download it and place it at the root of your SD Card.
2. Boot into recovery.
3. Factory Reset then wipe cache.
4. Flash the ROM then wipe dalvik cache.
5. Reboot!
Beastmod is still 2.3.5, you should consider flashing one of the 2.3.6 ROMs and maybe updating your Radio to the latest , much better battery seems to come with the newer update ...

Why would there be such a large discrepancy in battery life though from one T-Mo SGS2 with Beastmod to the other? That's what is making me scratch my head.

Umm yeah that too ... duh ....
There is a BIG change in 2.3.6 in battery life, at least what I am seeing and others have reported, some say it is the ROM some say it is the radio , I am using both, I get better battery life, but overall the SGS2 Hercules is a battery hog ...

Disable sync for your Exchange email. I found that to be the biggest source of drain.

I feel the same way my man..no matter which ROM I use, my battery drains like a mother
A lot of this can be due to signal strength. If you're in an area where you're constantly disconnecting/reconnecting to the towers, or you're just below the acceptable level for 4g, it might be switching between 3 and 4g, draining your battery.
Another thing to note, you usually want to run a rom for a couple of days before you start judging battery. It takes a while sometimes to build the dalvik-cache, and calibrate the battery. Sometimes as much as 3 full charges.
Lastly, look at what you have running on your phone. If you've tried tons of different roms, and they all drain, chances are it's an app you have that's misbehaving causing wake-lock. I'd try downloading system tuner from the market, and first going into the startup section. Remove ANYTHING that doesn't need to run in the background. You'd be amazed how many apps run at startup that really shouldn't, at least until you start them yourselves. Battery spy and cpu spy can be useful for troubleshooting what's draining your phone as well.

Thanks for the tips. I didn't give it a chance to do 3 full charges yet and I'll take a look into removing startup apps.
From the OP, it sounds like you have more than one SG2 phone available to you. Try swapping batteries to see if the same rapid discharge occurs where transferred.

I did try this but the issue with the draining is still there.
Have you tried changing kernels? Each phone responds differently to kernels and like some more than others. I've tried everyone and Faux's "stock" kernel works the best on my phone. It's UV, on stock speeds with a screen off profile.
To make sure your phone is actually going into deep sleep check the app CPU spy on the market. it'll tell you what clocks your phone is running through and staying at for the most time.
Also, check out System Tuner to see what rogue apps could be running constantly in the background [se Bloatware Freezer to freeze or remove apps as necessary] as well as if your 2nd core is staying offline and not staying on when it's not needed.
I would also throw your phone into airplane mode and compare the drain with no data activation to how you normally keep it to check if the 3G/4G toggling is draining your battery.

[Q] High battery drain because of Android-System

Hello,
I have a high battery drain because of "Android System". I lose about 3-5% per hour of my battery in idle state. I turn screen off and didn't use it.
I'm using Slim ICS ROM with franco kernel #174.
Badass Battery shows me that following included processes are in Android-System:
Code:
com.android.systemui
system
android:ui
com.tmobile.themechooser
surfaceflinger
com.android.settings
servicemanager
So anybody know what's the problem here?
I'm already disabled Google Photo Sync, NFC and GPS because I didn't need that. Also googling for the problem doesn't help.
Hope you can help, thanks!

Again, I've mentioned this twice today: Bullsh**, I don't mean to be disshonouring, or anything, but please, give proper answers,. It's all good, that you want to help, but only with proper and correct answers.
Right, back to topic;
Go into your dev. settings, and uncheck everything that doesn't need to be checked (Stay Awake, Strict mode, etc.) Undervolt the CPU, that should save a ton of battery charge, and underclock to 900-920 MHz, that is definitly enough, on a dual-core
Thanks for your answer =)
I think my phone is already undervolted through Smartreflex in francos app and I also tried underclocking by setting max cpu to 1036 Mhz (instead of 1200 Mhz).
The problem disappeared after 1-2 charges (don't ask me why..).
And now after flashing Slim ICS 3.9, battery time seems to be ok (for me at least).
Per hour in idle state the phone consumes ca. 2-3%.
I ask myself how do others get 1% drain over night. Is that even possible? Tried very much kernels (franco, trinity, glados and leankernel) and didn't even get near that.
Any tips?
OP Im glad you mentioned the issues went away after a few charges. this has been an issue for some who do not believe that a few charge cycles does anything. well im with you as i always see things sort of "settle down" after a few days of flashing a new rom.
I have the same problem on my Nexus S.
The process consuming battery is surfaceflinger. I can see it on battery screen before the name change to Android System.

Just wipe Battery stets after flashing. It needs few complete chargings to calibrate the battery.
There are also many apps in the market for this

Yes, it is possible. I get 1 or 2% drain overnight with wifi and mobile data disabled, and up to 5 to 6% if mobile data is enabled overnight.
My record with it is 1 day and 20 hours from 100% to 3%.
I had a LG Optimus Black before and didn't last a day. I'm loving this Galaxy Nexus.

I would like to achieve battery drain like that, seems like what it should be.
I am running AOKP Build 2 and I feel like my battery life is ok but not great. I let my phone sit overnight last night with sync off, but LTE on and it drained roughly 4% an hour. I actually turned off LTE in the middle of the night to see if there would be a difference, and no, it drained at the same speed on 3G as well. I live in an area with pretty good reception actually, GSam says I spend the vast majority of my time with a signal strength of 4/5.
GSam reported that roughly 34% of my battery drain overnight was due to Phone Radio. Another 52% was due to app usage. Drilling into that it tells me that over 40% of the battery drain from apps came from "Android System", "Phone" and "Kernel". Under Android System, which was by far the greatest drain of the apps, it only kept the phone awake 1m18s overnight so that doesn't seem excessive. However, I'm confused as to why, with a good signal/connection my battery would drain at nearly 4% an hour whether connected to LTE or CDMA. Unless the radios in this device are poor, I have a hard time believing there isn't a way to fix this without using something like Juice Defender.
I can't recall because it's been so long, but I don't really remember any ICS ROMs draining this fast. I'm on a clean install of AOKP B2 and I've tried a few different kernels with the same results. Any ideas anyone?
So I wanted to let you all know that after trying a few different ROM/Kernel combinations all with similar idle battery drain, I installed the latest (9/21) CM10 nightly and I only lost about 10-12% overnight last night connected to LTE. That is a much better drain than the 30% or so I was seeing previously. Not sure why but my phone just hasn't been handling the latest AOKP builds very well. I am afraid to try a different kernel right now as I'm leaving town tomorrow for most of the week so I'll leave it as is until I get home next weekend, and see if I get this good of battery life with the latest Leankernel.
Surfaceflinger
The same happens to me, this app appear in BetterBattery stats, Surfaceflinger appear as the culprit of my 45%+ battery consumption caused by Android Sys
When I first rooted my phone (xperia S) I noticed an 31%+ energy consumption by Android Sys, I reflashed and re-rooted and stoped for 2 weeks or so, now 2 days ago I woke up to find that 81% of the battery is being drained by Android Sys, then it lowered to 31-43%. I noticed that when I refreshed the stock "Battery" app ,"Surfaceflinger appear for a moment, I seem that I confirmed with the BetterBatteryStats, Surfacaflinger appears at the top.
Why is this happening? Can something be done about it?
PS: I cannot change kernel, bootloader is locked...
Surfaceflinger and android.process.acore are top battery drainer. I mean how to make them not sucking on battery?

SOLVED: ICS Upgrade Myth Dispelled - Factory Reset Does Not Fix Battery Drain

EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.
It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.
You might also want to get a battery monitoring program and see what is using the battery up.

its not a ics glitch its your phone lol.. ive never had this issue.. plus with the source kernels coming out and with roms/tweaks already out youcan increase battery life yourself.. because your battey cant keep a charge you bash ics? go back to gingerbread then lol. i can use my phone for two hours and leave it off charger over night and still have at least 50% charge

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.
Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.
This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.
Confirmed, factory reset battery drain exists.
OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

You guys need to quit crying wolf and figure out what is really draining your battery. Maybe your google drive is syncing, or you have facebook running, or email is pulling too often, ICS does not kill battery rogue apps and wrong settings do.
Try this https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats (search xda for other versions)
and this https://play.google.com/store/apps/details?id=nextapp.systempanel&hl=en
Figure out whats waking up your phone and running when its not supposed to be and until you have data STFU

seconded, attached is the battery stats for an average day for me on ff18 based goodness.... these "problems" are all able to be resolved rather easily with very little effort... this is not a paid tech support forum and no one is going to spoon feed you when solutions have been posted countless times in countless hysterical threads like this

My phone is not rooted and this is the battery life I'm getting after the OTA with light use. With regular use I get at least 25-30 hours.

Just curious, what's your display time. From the looks of it, doesn't seem like much. But still, that's pretty impressive nonetheless.

It looks like your phone may never be going into deep sleep. Get CPUSpy from Google Play and see what is going on.

So if it's not going into deep sleep what's the fix?

I'm a super n00b, if you or someone could link me to the best ICS ROM the cool kids are using I can figure out how to install it.
-----
However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

[Q] CM 10.1.2 Terrible Battery Life?

Hello,
I have had Cyanogenmod 10.1.2 for awhile now and i have only had one issue. My battery life has gone down dramatically compared to the stock touchwiz rom. I usually take my phone to school on standby and airplane mode and i loose about 20% in 3 hours. If I use the stock rom I loose about 4-7% in 3 hours. I looked in the battery settings and it said Screen, Google Play Services, and Cell standby took up the most. I'm thinking it's the kernel but I do not want to take the chance of flashing a new one. If there is any other solution please let me know.

you might need to re calibrate your battery.
also, check if you have any wake locks using better battery stats.
Here's a recent thread where they are working on similar issues. Won't be exact to your situation but may help you to track it down on your own.

Also, in the stickies, I suggest you read Woody's battery thread for a better understanding of some common issues and power saving tricks.

If you are putting the phone in Airplane mode, make sure the Location Services are off.
using themes and live wallpaper also is bad for battery. really bad!
i installed CM10.2 on my old Samsung Captivate and gave to my mom to use. Turned everything off and I'm getting excellent battery life. She gets 4-5 hours of talk time and still has 70+% at the end of the day.
