I was just wondering on how long your battery life was, I guess when comparing to idle time. I ask because this was the main issue of mine as to why I havent flashed anything. When idle I was getting up to about 3 - 4 days of battery.
If battery life is important to you I would avoid all ROMs other than stock.
Flashing 3rd party ROMs is likely to damage you battery calibrator which causes you battery life to drain rapidly since calibration gets all screwed up.
Nobody knows specifically what is causing this serious issue but what we do know is that it happens when you flash a 3rd party ROM/Kernel.

custom roms usually use the stock kernel. what you get on your stock rom, you should get on a custom.
battery life is also subjective and variable, depending on your useage patterns, etc.

Once again... lick my butthole 5thelement. Man you really bring out the class in me tonight bro.
I've been using task650s ROM with great battery life. I did have the battery drain issue which I don't think is really ROM related but once I went through the suggested calibration on this forum everything has been great. Think I've had my Tab on for 5-6 days with it at idle through the night and earlier parts of the day and using it for internet browsing and music around the house each evening. Turned it off last night with 30-40% battery left (just a guess).

Yea I am familiar with screwed up battery life calibration on my Captivate. I was getting anywhere from 8 hours to a day and a half which was why I was asking.

Really? Hmm thats good to know, I will look into that one then if I consider flashing.
Heavy usage (a lot of browsing, notes, some games) nets me a little over a day. My usage can be heavy and nonstop.
My average is around 2 days before I have to charge. That's mostly moderate heavy. My usage is abnormal but I can say I'm happy with its battery life.
Using tasks rom and pershoots kernel.
My usage is heavy everyday so I get about 7 - 8 hours of screen time by the time I go to bed and usually I am around 30% - 35% left. I use it all day for when I am on the train or in class. Running Starburst KME at the moment but I got the same average battery life on all ROMs using stock kernel. Pershoots kernel is reliable and I could go an extra day if I wanted.

yeah, battery life for the galaxy tabs seems to be pretty poor! i just can use my 10.1v (stock) for only about 3 or 4 days. just for a little bit of wifi surfing and ebook reading (wifi switches off during standby).
i really love my galaxy tab, and i hated my ipad, but regarding battery life i used to charge my ipad only once a month!!! really. and i used it exactly for the same things as my galaxy tab.
samsung promised it to have similar battery life as the ipad...one more lie from them...

I have been flashing back and forth ROM and Mods... I felt my battery getting worse compare to stock (stock Rom removed lot of ATT craps and other unused app).
Now doesn't what Rom i use: S8, Unname and CM7. My battery died at the end of the day which should last 1.5 days as my normal use.
Hmmm... well I jumped onto the ship already.
But I have to thanks for all developers that cook Rom. You guys are best.
Battery lifestyle will improve once you build up cache. Was battery life good when you first got your phone? Probably not. After awhile battery life gets a bit better.
Sent from a Galaxy far far away...
I noticed the same thing when I flashed from UnNamed to S8.
I followed some other users' suggestions and reflashed at 100% battery life, allowed the battery to discharge all the way until the phone died, then charged all the way to 100% again without taking it off the charger. I just got 25 hours with moderate usage and about 4 hours of screen-on time.
download the batteryCalibration app from the market, it requires root and makes you charge to 100% first. After that let it drain and it should do better after a couple cycles.
If you delete your battery stats in clockwork the phone relearns them and works better. But it will be ****ty for awhile

None of these do jack on our phone. I've read the kernel source for our fuel gauge driver, clearly none of you haven't and are blindly applying HTCisms to a Samsung phone even though I've posted MANY times that diddling with batterystats does NOTHING WHATSOEVER on this phone.
If someone's experiencing bad battery life after flashing a new ROM, especially a debloated one like Unnamed or S8, they most likely installed a drainer app.
If you run Skype, nuke that crap from your phone ASAP. It's a known battery drainer, and it's particularly insidious because of how it drains the battery - the usage shows up as Android OS but it's Skype that is at fault.
I just got the View for my wife to replace her Kindle Fire and it has terrible battery life running HC. I have it in airplane mode and I have tried a number of battery life tips that have worked on all my other Android devices and nothing is working. For instance its been on battery for just under 5 hours and just barely over 1 hour display on and its at 35% right now. I used to have the Flyer and it was pretty decent when it came to battery life but the View is terrible. Am I missing something?
The flyer was wifi only. The view is running a mobile data plan. If you want it to get battery life like the flyer then turn the mobile data off and only use the wifi.
This is what I do with my view and I am usually trying to kill it at the end of the day to charge it. I'm on it constantly throughout the day as well.
My battery life seems fine. I use it off and on throughout the day and I have the Cellular radios on most of the time.

Its not normal and hardware is unlikely so check the battery usage stats on the settings menu and see what is using the battery.

I have been monitoring the battery stats very closely and it doesn't make sense what is causing so much drain. I even have Better Battery Stats installed to monitor partial wake usage and nothing is out of the ordinary. I've never received a device with a bad battery but I'm thinking this might be the first.

i think you did that does not sound normal mine last all day with heavy use i can say i have never had it go all the way down...you may have a bad battery it just doesn't sound like the two i play with in fact one on gb the other on hc and the hc is lasting more....
Aside from a possible bad battery, you might have a corrupted battery stats file. Try clearing the file by deleting it if you have root.
Wait a few days. I think the same thing happened to me. Maybe for the first few days the battery indicator is not very accurate.

We've had it since 1/31 and it hasn't gotten any better. I've been doing some more testing and it seems as though wifi is the culprit. In airplane mode without wifi on it seems fine without use and doesn't drain. With wifi on the battery usage shows a constant drain without any use.
Try out my rom. All my testers and users report much better battery life than the stock rom, and I've got a couple extra things under the hood.

I just picked up a view off of CL. Same problem.. Horrible battery, didn't even last a full day.
People make fun of the ipad, but that 10 hour battery is no joke. This thing, with cell radio off and wifi on, lasts me MAYBE 5 hours, and thats with medium usage.
That's insane.

Now don't just assume all Android tablets are like your experience with the View. I'm confident there is something defective with the one I purchased. I had the Flyer and it would last me a good 7 hours and I currently have the Galaxy Tab which easily gets me over 9 hours of actual use (ie screen on).

I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?
Thanks!

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.
Note: Wifi is off.
Maybe 3G/H+ keep toggling for sync process?

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
I've had a stock s4 battery for a while and recently its been draining pretty fast. I've changed roms many times but the end result is always still the same bad battery life. At this point, I'm wondering if my battery is just degraded. I drain 10 percent from 2 hours idle . Also, wakelock detector isn't detecting anything unusual.
Does anyone have experience with a degraded/bad battery? Besides a bad battery life, is there any other defining feature.

check to see if the battery is physically swollen; somewhat common problem for the s4. the swelling may only be slight, but if you're able to spin it on a flat surface, you should replace it.
Mine has been that bad since out of the box. Worst performing battery out of any Android I've ever owned. It's my only gripe about the phone except for the locked bootloader. Like you, I've tried virtually every ROM out there and its always the same issue. I was hoping a blacked out ROM would help but it hasn't really.
I ordered a zerolemon 3000 mah battery to replace the stock one. Hopefully this will fix any battery issues.

Interesting. Would you mind posting your experience back here once you try it out for a few days? I suspect you will need to calibrate it when you first install it too.

Yeah, I can definitely do that.
I am currently running debloated stock .305.
I am not overwhelmed by the battery performance. my z3c with slim rom was much better.
So i wonder if i could flash another kernel and improve the battery performance.
So if you guys have some experiences that they will share i would appreciate it.
thanks in advance for any reply.

I'm on the xpower rom and it's weird: during 8h of sleep it only lost 1% of battery, after 10 minutes of browsing and whatsapp it lost 10% of battery. Unacceptable, "screen" is taking most of the battery as there doesn't seem to be any other battery intense app.
Does anyone have any idea?
Sounds like you have 10% drain in 8 hours with light use. That's 1.2% per hour. I think that's pretty usual... And yes, screen should be the most demanding component unless you don't really use the phone. Try lowering the brightness, the effect is almost exponential

Not really, I have 1% over night (which is great) but then 10% in 10 minutes as soon as I start using it (just browsing the net).
I would assume it's just not getting the levels right just after sleep, in fact you've lost 8% and another 2 while using it.

you think so? I rebooted it several times and it would always show the same %, only to drop drastically as soon as I used it. It's really weird to see the battery going down while using it for just a couple of minutes.
Battery % is always a guess.
It would be much better to actually use the device for a few days and then deduce how much battery time you get according to your own usage.
Im using XPower as well and notice the same issue. Battery can last forever screen off but then drains quickly when on.

Well compare to the latest stock firmware the battery seems to be night and day. I can easily get two days with light use. The battery drain on stock seemed to just be constant.
