Anybody else experiencing pretty bad battery drain with blackhole 2.4? Known issue? I don't want to reflash back to an older version without confirmation because it's a bit of a hassle.
Don't mean to come off crass if it sounds like that, but it's been rather severe the past few days.
Running stupidfast 1.54 fwiw.
Thanks for your help guys.

I noticed that when I first started using blackhole 2.4 I had awesome battery life, now it has really started to trail off. I can get through the day, but it's pretty low at night.
31% in about an hour... Can't be normal right?
Also I've turned off bln for now because I assumed that had something to do with it.

If I dont use it overnight it will go from 100% to 45% in about 7 hours. If I am reading the news and just surfing the web it goes from 100% to about 60% in about an hour.
Not sure if it will help, but try charging to full and wiping battery stats in "advanced" in clockworkmod

31% per hour is too fast, when with display on and heavy use. I only burn battery like that if I leave bluetooth or wifi sharing on. Perhaps brightness is on full. Maybe something quirky in your kernel install. I've seen no battery life change, positive or negative, with blackhole 2.4.
I let my battery drain completely, and charged the phone while it was off to 100% and reset my battery stats. So I'll be testing the runtime now under average use as earlier today. I'll report back with the time in this thread when I can.
try doing *22899 instead of *228 it helped me a ton when my battery was going fast. My battery would go randomly 5% every hour in standby until i did this. Now it goes maybe 1% every 2 to 3 hours.
Usage is much more acceptable now. Btw what's that *228 stuff?
Edit: I looked it up, why would I need to reprogram? Regardless I still tried it out, let's see if it makes a difference.

Of all the ROMs and kernels I tried, I consistently got the poorest battery life with StupidFast kernels and BlackHole ROMs. I tried them individually so as to eliminate issues caused by the other (ROM or kernel), and the result was always the same. I can't imagine what the battery drain would be using them together.
I'd try swapping out the kernel since it's the easiest to do and see what difference that makes. Geeknik is no longer developing or supporting the StupidFast kernels, so they're a bit of a dead end at this point anyway.
I get pretty good battery life pairing blackhole with jt 11/29 and a properly rejuvenated battery (sucked to death then overcharged while off once a month or less). Not sure what causes your issue, just want to add that not everyone had the same negative experience.
In terms of geeknik, he is absolutely still making kernels last time I checked, and people still love them religiously. I personally have not had a lot of luck pairing stupid fast 1.54 or 12/20 with black hole, so one may have better luck with super clean for those kernels. I have no idea why, or if my experience is isolated. Human nature prevents me from spending a lot of effort testing configurations that don't work well for me.
In terms of reprogramming your phone with *228 or *22899 (or *22800, whatever that does), you only should be concerned with that if you are getting a lot of signal loss in your standby mode battery stats. It resets the PRL, which is the list of local compatible towers the carrier authorizes your phone to use. More towers means less signal loss, especially relevant while traveling. Now if someone could explain to me why both phones and pdas are too dumb to manage their own PRLs, that would make my year!
Edit: Apparently I have no idea what I am talking about. The link in the next post indicates that geeknik no longer owns a Fascinate and its no longer developing kernels for it. My error.
Swyped w/ XDA App. When in doubt, mumble.

Oh, ok, perhaps something has changed since his latest post here.
Still, I consistently got lousy battery life with his kernels, and honestly, I saw no objective improvement in speed. To be fair, I don't see any speed increase in JT's kernels either. I suspect the majority of people's lag is in the ROM, not the kernel.
Well I'm not experiencing any issues after I did the battery stats wipe last night, so it's probably not the kernel and rom pairing.

I have been having serious battery problems every since I got the phone.. the other day I installed Blackhole 2.4 running JT's 11/29 kerenel.. also running DJ05.. obviously... and I haven't been this happy with my battery to date! I am getting a good 16 hours of pretty heavy use where as before I would only get 10 hours maybe.. my battery would drop 30 percent at night before.. now it only dropped 11 percent.. still too much IMO but a lot better than what it used to be!
This is not something i've ever had issues with personally, however I do completly drain the battery and fully recharge it, then wipe battery stats from cwm recovery, every few weeks.

Wanted to start this so we can get a better idea of what kind of battery life we will be seeing with 2.2! Please post your opinions so far and if you are rooted/stock and using stock kernel or the .34 kernel cyan posted. Hopefully we won't see much of a decrease do to JIT or any other new features
Probably won't be that great the first couple of days...testing out Flash and everything...(watching Hulu right now).

i was on CM5.0.7t2, and as we all know, CM is known for draining more battery than the stock rom/enoms but so far im seeing same usage as CM which is ok but not great. next few days will be testing for all of us. hopefully we will have similiar usages not like before where some people are getting 40 hours and some 10 lol
I dont if theres an improvement but I updated on a full battery. After I had 97% then killed the battery in like 5hours while at the Engadget Show lol
is anyone running setcpu with FroYo? im already gettin horribad battery life...probably due to Hulu
I may have done something wrong, but I'm on a rooted phone with kernel 2.6.32.9-27220-g328f560 and my phone went from 80% to 10% in about 4 hours just sitting in my pocket. The most I did was check some emails and some basic SMS.
Will monitor closer tomorrow by my battery usage shows something like 19% email. I wonder if my outlook push is doing something constantly that is hurting it.
Edit: it's also charging REALLY slowly. I have it connected to a USB port and its taken ~ 30 minutes to go from 14-16%.
So far, mine is looking pretty good. Early days yet though.
Its better with froyo.
Had to charge every evening with CM 5.0.6 and pershoots kernel, now i get almost a half day more (with more "playing around").
I use setcpu (245/499 at sleep).
My battery is showing 99% after 3 hours switched on and with light usage. If true, that is amazing! More likely something is not quite right. I am using the .34 UV kernel from persionsown he posted on twitter....

If I believed that it were a true reflection of battery use and not a mis-report of some sort, I would be shouting about it a lot louder!!
i streamed about 1.5 hours of video via qik (uploading not DLing). Still have 60% battery left. I say that's an improvement. Rooted modaco froyo
I'm seeing what I think is significantly worse battery life since I installed Froyo. It's hard to say, though, because I've been playing around in ways that are different from my normal usage pattern (checking the market frequently for updated apps, for example). I was on stock 2.1update1 and now am on stock Froyo.
Battery life is definitely better than Cyano/Modaco/Enomther but it is also worse than stock ERE27. Can definitely make it through a day still though on moderate/slightly heavy use with Froyo something I can't do with Cyan/Modaco/Enom...and this is way faster and more fun than any rom i've had previously so no complaints from me.
Well I was running cyan 5.0.7 and it lasted me longer than this I have now, which is Paul's Froyo.. but since my wi-fi finally stays on I wont revert.
Question: can I still install older custom kernels on froyo???. Want to try...
My battery died sometime last night, and I had gone to bed with it 70% charged. Prior to Froyo, I was on CM 5.0.6 and usually using intersectraven's 925mv kernels, and I would lose about 1.2% per hour while idling.
I'm not blaming Froyo yet, since it could have been an app screwing around. However, the battery usage page didn't show anything out of the ordinary. It will take some more testing before I ditch Froyo until an update is released.
BTW, battery usage while actually using the phone seems to be about the same.
my battery life was phenomenal today. i can't give percentage, because i haven't put on a battery widget (or many widgets at all, tbh), but stock froyo treated me well. was above 80% (guessing by icon) when i left work after 8 hours, some hulu, some wifi, some texting, some phone calls. not exactly heavy usage, but not just idle either.

Check out Battery Indicator http://www.cyrket.com/p/android/com.darshancomputing.BatteryIndicator/
Great and extremely simple app. I've been using it for months. (And it doesn't drain battery either.)
I've been tracking the battery drainage and system usage of the omadrmconfigservice using the system panel app since updating to DK17 and it doesn't seem to kill the battery the way eclair di18 did. Is this just in my head or is anyone else seeing similar results?
I seem to be getting better battery life with Froyo. I also notice that the phone doesn't shutdown as abruptly, when the battery dies. The phone also doesn't take as long to charge before use, when it completely dead. Just flashed two days ago.

I don't think it is just in your head. After flashing to DK17, I more or less forgot about killing the DRM stuff at boot, and when using the phone only minimally, even with only 3g on (no wifi), I have gotten 54+ hours on a single charge of a stock battery. Keep in mind though, this was with really minimal usage, maybe 3 or 4 calls, same for texts, and about 1 hour with the screen being on. This isn't typical usage for me, more like an extreme case, but I was able to achieve this with nothing additional running or installed like juice defender. I dont have any screenshots to try and prove it, but my point isnt about bragging, just that the power management is fairly decent on the DK17 build (running Quantum 1.5 if interested)

I posted this in another battery question thread. It also helps that there's a native option to disable data. It's a great feature on Froyo
Ok, first up I am not a developer, not would I know how to develop for the phone.
With that said, I've noticed a repeatable chain of events that I think have caused at least in my own situation poor battery life from certain modems.
I noticed that after flashing for instance KA7 on top of a previous installation of KA5, KA6 or even JK6 that battery life of the new KA7 modem was horrific. My base ROM was usually always Nero or Bionix
Then I completely changed to the new Bionix-V ROM which is based on KA7 and voila, my battery life is great.
Could it be that the process of flashing different modems causes some kind of internal confusion with the phone that relates to undesirable battery life?
Just an idea, but it's like I said something I have been able to repeat, and perhaps others have had the same experience.

Instead of responding with a useless post and armchair modding, you could just not post at all and let the moderators do their job. It's posts like yours that cause people to run out of here. Just blatantly rude.
I don't know, but I think it's possible. Sometimes, flashing over causes every kind of problems. Why not?
Isn't that the reason why we clear battery memory after a flash? So that there is no confusion. :-\

Never underestimate the power of placebo
Reset the battery stats via recovery and after a full cycle or two you probably won't notice poor battery.

I should have added that I ALWAYS wipe battery stats when making modem/ROM changes - following the usual guidelines.
However, my experience still exists.
Specifics:
Nero V3 Running Voodoo+JK6 = Approx 30 hours battery on light/medium use
Nero V3 Running Voodoo+Updated KA7 = Approx 12-16 hours with same usage
Bionix V running Voodoo+KA7 = Approx 30-36 hours with same usage
It's not placebo - it's a measurable, noticeable difference.
i get good battery ;life out of stock ka7 no bloat prolly around 30h and for instance i had bionix and my battery was sucked up llike no tomorrow thats why i am back on stock
I think the PLACEBO may more correct answer, Since JK2 and on battery has been not a real issue. Every time you flash a new modem etc, if you think you need to (I do not think it is all that important) go into recovery and go in advanced and do the clear battery stats and go from there......
The only Time i have ever had a real issue with the battery life with custom ROMS is when using over-clock roms.
Other than that, I would guess you are using the phone different every day, and do not think so imho. That is a more likely cause of battery performance or lack thereof.
with bionix my battery lasted half less
Is has a lot to do with how much battery you have left when you flash a rom. I always flash with a complete full charge and never really see a difference in battery life going from rom to rom. My battery always last about a day and a half with every rom I have tried. Also I have not once wiped battery stats. This is only needed if you do flash with a battery that is not fully charged.

I apologize but take away about 10 hours of just idling while your sleeping at night, that doesn't count... I could keep my phone asleep with no widgets, 0% brightness, etc. but what's the fun?
As long as your phone lasts you the day, or as long as you need it to, you shouldn't be worried about it going for a week on one charge...

exactly.
Your battery needs to last maximum of 15 hours, unless if you work 24/7.
your going to end up charging it at night so why the hell do you care?
I'm curious about the 20+ hour battery life cases if you have background sync enabled.
I just requested a new battery as my old one I believe is going bad. Running JFD --> JK6 --> JK7. Charged battery to 100% while off over 3 days. (Letting sit all day at 25% 75% and 100%). Resetting battery stats tonight and staying at 100%. I'll see how the new battery compares. (My old battery life was 8-10 hours max).
can we mod the vibrant so if we shake it hard and long enough battery will charge like in those those flashlights ,

Na I would rather use my phone as it was intended a smart phone. One should get a day out of it Then plug it in at bed time.
Hi all!
I have been using CM7 RC1 for a while, and recently upgraded to Builds 6 and 7 in order to get 4G working.
I did not wipe when flashing 6 or 7; just flashed the ZIP from the recovery.
Where I would have previously gotten 18-24 hours of use, I now get 4 or 5! It's amazing.
I'm 4h17m off the charger. Display time is 17% (1h33m), Cell standby is 29% (TWOS 6%), Maps is 20% (used it for a little bit while in the car), Phone idle is 17%, and Wi-Fi is 14%. Battery life is at 9 percent.
I'm just surprised at the bad battery life, especially after having real good life in CM7 RC1. Nothing of substance has changed other than flashing Builds 6 and then 7.
Like I said, I did not wipe anything before flashing. Should I have? I might try it, just to be sure...
Others who have CM7 Builds 6-8, could you tell me how your battery life is now compared to RC1? Is it noticeably different? This has been a tremendous drop-off for me, and I'm suspecting this must be some sort of fluke.
Thanks for the input!
This doesn't belong in Development Section.
You're right. My bad. If there's a mod around, please move it!
More than likely it's because of the lack of wipe.
also, hit up the sig for additional stuff if you're still having issues

I'm having the same issue, flashed yesterday, I was fully charged when I flashed CM7, but I spent about an hour playing with the phone and was at 60% when I left the house to go to work. My phone died within 4 hours, it was on standby all that time as I didnt get a chance to play with it. It was hard to gauge if the Rom caused the drain or if it was because it was already low on juice. This moring I was at 100%, flashed the Savage 1.0 Kernal (in the hope that it would enhance the battery life), reset the battery stats when the phone was at 100%, it stayed there for about 26 mins then went down to 99% (on standby for 26 mins). I left the house, put my phone away at work, received 2 emails, 1 missed call in 5 hours and the battery is at 46% WTF!!!! I really like this ROM, but I really need to know what is causing the issue. The setup is the same as I had on the last 2 ROMS in regards to WIFI and GPS - bluetooth is always off.
Not running on fresh (for now anyways!)

Yeah this issue has been plauging me for awhile. I'm all for system panel pro (love the app; one of the first apps I bought), but it won't help in this instance. The problem is that the battery isn't charging as fast as the numbers say they are. The easiest fix (sadly, as I hate the risk) is an SBC kernel. That way, even though your meter will say 100, it will keep charging till it actually gets to 100. Without SBC, your phone will think it gets to 100 from 50 in an hour (it's probably at about 75) and will just start dying down to 65 (instead of 100 to 90). This means that you could unplug your phone at around 50 percent even though it says 100. The SBC is a good way to confirm, as is just turning off the phone and bump charging (check the link in my sig for the how-to). I'm really curious as to what is going on with the battery meter readings, maybe some dev can comment.
Hope I helped!
I'm using build 6 with Savaged-Zen kernel and I'm getting the absolute best battery life I've ever gotten with my phone. Like others have said, try wiping cache and dalvik and reflashing the rom. If you still get bad battery life, try Savaged-Zen kernel. Its fantastic. I'm currently using the CFS version 0.1.2.
Did you flash gapps right after flashing cm7? Also, have you checked if the "Dialer" is causing wake lock using spare parts?

Rest of us live in 4g land. Using a generic rom with 4g and tethering working- is better than touting these purist roms- that dont Do what Needs to be done... while some kanger kid seems to make it run just fine....

There was nothing out of the ordinary in Spare Parts. "Dialer" didn't appear to be misbehaving.
@noirelion, I should have mentioned that this is with 4G off.
@Leukay, that sounds really great! Would you mind elaborating on what kind of life you're getting, roughly?
I'll probably end up wiping and reflashing. Since I have Titanium Backup, it's not a huge deal. Just was wondering what in the world was going on!
I've been getting 20+ hours with nightly 8 stock kernal. So definitely try wiping

CM7 Wimax works fine for me. Tether, etc. Stock kernel, Savage-Zen, both work fine. Battery life is acceptable, even more so if on a SBC kernel.
Something is definitely wrong with your install. I'm running nightly 6 with stock kernel, flashed over nightly 5 without a full wipe (wiped dalvik and cache, flashed gapps) and I just got 68 hours of battery life with 28% still left.
Try rebooting to recovery and wiping dalvik again, sometimes on first boot some strange things get cached, and a second dalvik wipe after the first boot can fix some strange behavior.

definitely a problem. i was getting 18 hrs (first light then heavy once i got out of school) and now get like 22 estimated with tiamat's noSBC (thats the 3.12 version) same light to heavy situation. try turning off data manually when u dont need it. helped a lot for me. tiamat sleeps like a baby, and gets high 1500's in quadrants.

Nobody has managed to get 4G working on an aosp rom other than teamwin for cyanogenmod. The reason sense based roms work is because HTC did the work for them. 4g for cyanogenmod was coded from scratch.

saw in another post that some guy said although there wasn't real proof he was to afraid to risk it.
there is no real proof that cell phones cause cancer but he carries one of those around.

Hello all
I have been roaming around XDA for a very long time now and I finally made an account because I simply cannot find an answer. I have a samsung vibrant and not the 4g nor can I upgrade(long story). I use my phone when I need it and i text alot. But lately my battery life hasn't been any good, I've tried reconditioning and the whole bit and nothing seems to give me my needed battery life. I am currently using ICS passion 13 RC1 and it works great, when Im not doing anything -.-; When I use it like for the internet or text a lot it drains. I got to 48% in 2 hours one time and thats with limited background processes. I know ALL about the keeping background proccesses and data using apps down so I hardly have any apps installed, which is very irritating at times, I dont even use the facebook app for that reason. I tried many different roms and it seemed Axura had done that best at one point but it was taken down or is no longer supported for whatever reason so I am now in search for a rom that can get me through the day. I text a lot and web browse occasionally. I dont have wifi so i cannot use that to save battery life while surfing so thats out. I would appreciate all the help and will try every rom if i have to lol XD
I appologize for the long message but I am so tired of hesitating to use my phone as a smart phone.
I get good battery life on the ICS Euphoria ROM. Your battery could be shot, you might try replacing it.
Any of the 2.3 or newer roms are going to get bad battery life. Fishmanmod's updating of Bionics has been very smooth and getting great battery life for me.
I find that battery life between 2.2 and ics is pretty much identical for me as long as there are no wakelocks preventing deep sleep. I'm currently on CM9 nightly w/ glitch kernel and deep idle enabled in nstools and have no battery life problems.
You could also look into getting an official 1800mah battery if you really need more juice
ICS Slim hands down the best.

Your issue is Passion. That ROM chews through battery worse than any I've ever used in the 2 years I've had my phone.

Its not just your Rom, I am on the CM9 nightly and noticed ICS ate my battery by noon today. I was down to 3% from 7am. Granted I am toying with it a bit more but I was still at work so I couldnt use it non stop and I wasnt even watching videos or listening to music on it. I have updated the kernel to SubZero 34 to see if that helps.
Chances are, your battery has lost some of its ability to hold a charge. I recommend buying a new OEM battery, chances are it'll increase your battery life by a good two or three hours.
So far, I haven't noticed a significant variation in battery use in various ROMs, I've found battery life to be more determined by the kernel.

On a side note, I destroyed my screen by stepping on it a few weeks ago. Ordered a new AMOLED screen (not the LCD knockoffs) and battery life did in crease by about 3-4 hours. Same OS, same battery.
So I think some excess drain could be caused by the screen, which might explain why some phones had such poor battery and others don't. I also no longer have the "graying/shadow" issue that plagues some of these phone.
So far ive had the best battery life with ICS passion RC2.1 and my 1800mah anker battery
Since flashing CM9 and then putting on the SubZero kernel (34) I did a full charge and decharge to test and got 12+ hours on it with my normal use. So I have to say SubZero kernel really helps out if you are on ICS.
I f you dont mind going back to a 2.2 rom I would suggest trying bionix 1.3.1 fishmanMod or Deranged9 fishmanMod alpha 1 both get awesome battery life especially when mixed with juice defender.
I was also using ICS Passion and noticed a significant degradation in available battery life. I have three batteries so I'm confident it was the From. Until then I had been using various Froyo rooms and all seemed to have better battery life than ICS. I personally felt it was more likely to be your kernel choice that would impact battery life. I just switched to the SLIM ICS from and I gave been very impressed with both the battery and the responsiveness. Same quadrant scores as Passion but it feels so much faster

I haven't taken the dive into ICS yet i may have to try that out.
If you r searching for nice n smooth rom try
[4.0.4][6-Apr]Slim ICS [3.2]

another thing you can do while flashing wipe battery stats only once....then reboot to normal drain your battery till it reaches 1% charge it full widout any interruption and when it reaches to 100% unplug it and do the calibration from any software available in the market I use Battery Calibration Professionals

repeat the process for atleast 3 days in a row and you will feel the difference..hit thanks if it helps
@OP ICS is simply not battery friendly. You're going to want to use froyo if battery life is that important to you.
Or you can build a battery friendly ICS rom and let us know how it all is
The later builds of Cyanogenmod9 I have been on the stock kernel and its going all day with moderate use without battery issues.

Bionix Fishman Mod is the first custom ROM I've ever installed on my phone and it's battery life is AWESOME. I recently added an 1800 mah battery and I've had 24+ hours on one charge with moderate to heavy use. The ROM itself is smooth as glass and no glitches to speak of.
Trying Bionix

I just installed bionix-V FishmanMod Final 3. Fingers crossed. I don't mind switching back to 2.2 as long as I have better battery. However I did notice when I reinstalled ICS before going to bionix that just factory, not even logging into the market. I got 1 day and 7 hours of battery life, granted I did not do much but text occasionally and some web browsing here and there. Is it possible that the android market is constantly checking on stuff or there is some data being proccessed constantly? I do live in an area where my signal is not great for 3g like 1-2 bars.

Alright so after about a day with the rom, I noticed it's just as bad. I am still getting battery drain and yes I have a new battery in so it is not that. I unplugged it from around noon, did alot of working on it with reflashes and little bits of texting and mostly just scrolling around the O.S. im now at 44%. its been about 5 - 6 hours.
Although I have been switching the battery between 2 phones and their battery meter is very different. like a 5% difference so that may be confusing it. Will update.
