Awful Awful battery life since Darky's ROM

I have always had stock ROMS with my i9000, ending with JS7. I read the battery problems people had and I always counted myself very lucky that my phone had a pretty decent battery life.
Daily I would SMS (a lot), the odd phone call, quick blip on the internet (3g), lots of angry birds and doodle jump! I would get at least a couple of days before it went into the red.
Then I made the big mistake of installing Darky's ROM, it looks nice and feels a bit snappier, but now the battery is in the red in the evening after a full nights charge. This is even after severely curbing my phone use to try and extend the life. I have tried all the wiping tips and tricks too.
Same apps, different ROM. Darky's is an absolute nightmare for me and I will be going back to stock.
So is the ROM just another variable in the mix of battery issues, or the main offender?

Hello. I've the same battery drain, and I think it's very annoying when at evening you need to charge it again without using strongly the phone. Otherwise the Darky's rom, (I'm on 9.3) is very nice and marvellous, but this battery drain issue makes it worse.

Have you tried using spare parts to see which app is sucking baster or cpu? Did you download the rom configure tool from the market? Which gallery did you instal worth the rom?

This and:
have you let the phone drop below 10-5%?
Flashing screws up the battery indicator (how much depends) and it calibrates itself while in use. Letting the battery fall, or even the phone shut down by itself can speed up the process quite a bit. This helps only if there is no battery hungry app that's eating all your powrz though.

I haven't tried to see if there is an app sucking the life out of it because I never had any issues under the 3 or 4 stock roms and I haven't d/l any other apps. The battery deterioration started instantly I flashed with Darky's. I don't know which gallery it is, it came with the d/l. What ever it is, it doesn't work! No, didn't use the configuration tool.
I must admit I haven't let it run under 10% as I want my phone with me working. But wouldn't this manifest itself when I updated the stock firmwares?

ok mate, firstly search the market for the Darky Rom Configurator, shoudl be easy to find, you shoudl be able to reflash without wiping all your apps, run the config app first and pay special attn to the 'Lockscreen wallpaper' of the tool, there aint many options to choose. Got the gallery drain bit mixed up, sorry tired
If i was on my own PC id give a bit more detail but its pretty straight forward.
Im running 9.3 and get a full days mid-heavy use, i normally go to bed at 10-15% which is fine with me

cheers for the advice mate, I've just grabbed the app so I will do the flash in the morning.
I will report back my findings!

Just a thought but Darky's Rom uses JS5 and wondering if has something to do with the modem? Just a theory but wondering if you could replace back to JS7 and see if that helps. Just a thought. I'm used to a day's worth of battery myself these days.

The faster you make the phone go the more power you use darkest Rom are ok but messed with too much

I got really bad battery life for the first few weeks using darky. But now the battery life seems to be longer and more stable and average. I did do calibrations a few times tho.

You won't get better battery with Darky ever.
I played around quite a lot, 9.2, 9.3, calibration, fresh system, darky rom configurator, different kernels, lagfixes, no matter what, my battery drain was mad. It's a quick and smooth rom, but that's the downside of it.
I switched back to Doc's rom via kithen with same kernel, and quess what? No calibration, no playing around, nothing special I did and battery life is brilliant! Of course it lags here and there, that's Doc's drawback(no lagfix applied tho)

You will often find that if you flash a number of roms you get battery drain . Apart from the actual rom itself you need to flash to a clean firmware reset battery stats use a suitable modem charge battery once using bump charge method then wait a few weeks for it to settle down .
I am using rom kitchin since Darkys killed my battery life months ago .
JPY and JPY modem no complaints about excess battery life .
But i did flash back to clean stock before custom rom and wipe everything .

but this is true even if i use a kernel mod.. instead of a full flash? i think that a stock rom with custom kernel made for battery lasting is better... or not?

Have u all tried Battery Bump Charging?
Hi, I am not a Galaxy S owner but I am doing a research on this issue for a friend.
I am a Milestone user and I am a ROM slut (I flash many ROMs back and forth)
So I am very familiar with cases where after flashing a new ROM, your 100% fully charged phone is actually 60%/
Here is a posting on a few ways you can do a battery bump charge. When you perform this battery bump charging technique, u will be surprised to see that your 100% fully charged battery is actually not 100%

SE Stock Rom Advantage!

Hello All,
I noticed there are a lot of posts regarding Battery Usage & Optimization...
I tried many many combinations of custom roms, basebands and kernels and I always face the same battery problem especially when 3G/MobileData is switched on.
I admit that Sony Ericsson gave us a ****ty stock rom with poor kernel however It's still the best rom in managing battery usage.
I made a small comparison on Stock rom VS Custom roms with 3G/MobileData left switched-on and I found the following:
Custom rom(s): battery drain down very fast it goes for 100% to 1% in less than 8 hours (normal apps installed)
Stock rom: battery lasts for 2-3 days with normal daily phone usage (same apps installed as i did in custom rom)
Please share your opinions.
Thanks,
Ayman

I don't agree at all...
Custom roms can have just as good, if not better, battery life.

I personally think this was a good idea. Nice post and info. Just curious, how long did you do this study with the data you got?

hey guys, i too have this issue, i dnt know if its device specific. ive had the phone since march(2010) last year and have been modifying it with the great mods that the devs hav given us. everytime i install a custom rom i just get unusual battery drain, like yesterday, i followed instructions to the letter and installed tripnravers miuifroyo 1.0.8 and i lost 10% battery in like 20 minutes n ive hardly used it :-(. so nowadays i stick wiv a modified stock 2.1(ewjet to b exact). im gna buy a new battery and see if i get the same results. i really wna use a custom(2.2+)rom but the battery problems are really putting me off, theres so many people out der that arent really having ny battery drain whcih jus dus my head

Thanks Voelker BTW this is my first Thread in XDA, I used to use SE 2.1 stock rom till the first stable Froyo custom rom came out. I switched to Froyo then I started to notice this around 4 months ago and I tried many combination and a lot of optimizations to find out the best one although Stock rom was always better.
@fiscidtox:
I love Foryo and GB much much more than Eclair I currently on CM6 v6 Wolfbreak
Could you please tell me how the battery lasts on your custom rom while MobileData is left switched-on?
Thanks,
Ayman

I get a full day..
If you mean stock with no tweaks then maybe it would last longer, but a lot of that would be not having jit enabled...

You must be doing something wrong!
10% in 20 mins isn't normal.
I'm sure if you left it settle this would rectify itself though.

I think the biggest advantage of the stock kernel so far is stability, but the ongoing development for the custom kernel is sucessful to implement some problems such as battery drain caused by unability to go into deep sleep etc..

I never understood needing more than 24 hours on a charge. Charge it while you're sleeping you wont be using it then anyway.

Even if you like the 2.1 Stock ROM for any reason (Stability,Battery,etc) and don't like all these awesome 2.2 and 2.3, you should at least use Eric's JET ROM which is based on the original ROM has no stability issues and has faaaaar better battery life.
But seriously, I`m using Custom ROMs since the first 2.2 ROM by Z and never even cared to get back to the stock ROM.

When I use Wifi custom roms have almost the same battery life as the stock rom. But since I can't connect to wifi at work on any custom rom, im forced to use 3g.. and I need to charge my phone twice a day with almost no usage.

Let it settle for at least two days to see improvement.
Your battery needs to adjust, much like letting your phone build a cache, in order to really see how the rom will effect anything.

Im using the stock rom and my battery lasts a maximum of 2 days with this tweaks: http://forum.xda-developers.com/showthread.php?t=934486
I dont use 3g at all and i use wifi sometimes (session lasts only 10 mins or so)
Brightness is set to "middle" also

Sorry dont agree..
I use wolfbreaks latest rom with the undervolt module.
Juice defender only enables my wifi when i am at home...all other times i have data on with facebook sync.
I now get the same battery life as i did on stock 2.1
Currently I have been unplugged for 1day and 12 hours and I am still at 38%.

[Q] How to tweak rom/kernel for best batery life

Hello, i'm using typhoon latest rom with latest kernel from dorimanx (7.1A), but im gonna go on vacations and i really need my phone to last as long as possible, is there any way to tweak rom or kernel for better batery life? thanks

What sort of battery drain do you currently get on standby? Can you tell me the reading in ma from CurrentWidget? If it's 3-5 ma with mobile network/wifi/bluetooth etc on and 2ma in airplane mode then you're fine,but if it's higher it can definitely be improved.

If you don't plan to use mobile internet connection then disable 3G and turn 2G mode only. Turn off as many widgets as you only can, disable Location Service and auto sync. Install apps on phone memory only.
Also Dorimanx kernel is a hell of battery drainer, use another one like stable Tytungs etc.
Use dynamic/powersave CPU governors or use CPU speed profile apps like SetCPU and make several profiles for it.
This is only a few of tips we can give here.

im getting between 10 to 15 ma with 2g on and sync all the rest is off, and im using smartassv2 governator i dont know if this can be improved .. and i really like dorimanx kernel becouse it feels faster then tytung and it gets less hotter becouse right now is really hot these days and i nearly cant use the phone with tytung kernel becouse it gets crazy hot :O

Well the apps I use to reduce my battery drain are JuiceDefender and SetCPU. Set the profiles to be 245-576 Mhz when screen is off (smartassv2) and whatever else you like when screen is on. I never had any overheating problem with Tytung's kernel though. It was the most stable and just as fast as Dorimanx's kernel IMO. Still, using ICS now so I can't really judge about the newest versions of each of them.

I think his kernel is the same in battery drain over any of them. Ive tried them all. If anything, seader_r9 was the best and it was only a small improvement. My battery life is pretty short, but im a HEAVY user. Constant web browsing, constant text messaging contant GPS. And it lasts for the majority of the day. Now i have an .sh script which helps tweak the smartassV2 settings. I get about 110-200ma drain when doing simple web browsing or replying to a text.
One must also keep in mind that the ROM has a major part in battery drain as well. I heard from many users on here that MIUI has the best battery life. All in all i think any kernel you choose will have reletively (i spelled that wrong -.- its still early ) the same battery drain. It really comes down to the amount of use your phone has. But as stated before, turning off data greatly saves the battery as does turning down the screen brightness, fyi, automatic brightness sucks battery life too. Plus android does a horrible job polling the light sensor -.- it shouldnt take an average of 3 seconds to get the changed light value..
Theres not much 'tweaking' you can do to give you like an hour extra of battery life. Our batteries are only 1350mah batteries and thats really small for such a huge screen. My Touch Pro 2 has a 1500 and a much smaller screen. There are a lot of good aftermarket batteries on ebay that you could get which would extend your running time.

thanks guys, im gonna give a shot to tytung kernel, but im also gonna take a look to the aftermarket baterys

Typhoon rom support undervolt so if your phone is gettin' hot I suggest you to tweak the voltages as explained to original thread first page, it makes a big difference compared to stock.

Good advice here. There's a lot you can do (as already advised) but always some performance tradeoffs. The standard HD2 battery is only 1230 mA... not 1350. Smartassv2 in DM's kernels is excellent for performance and settles down nicely in standby - but it will pull-on your battery when used. There's no substitute for keeping a few extra charged batteries around (when you need them), along with AC & DC chargers + cable, in a small carrying case.

You don't need to use dorimanx's latest kernels, his stable kernels in fact do a better job at not overheating and have only 2ma drain on standby. I know 5.9, 6.3, 6.4d, and 6.9A (ics hwa) give a great battery life.

Which apps are running in the background? People constantly say that task killers make no difference yet whenever I've opened something and haven't killed it I get a higher battery drain than normal.
Also, use JuiceDefender and SetCPU to lower the drain.

Curious observation in battery life on ICS LQ3

I have noticed accidentally yesterday that after I had my stock headphones pluggeed in the Note, the typical curve of the battery drain became much flatter and the different wakes during screen off have almost disappeared. The moment I unplugged the headphones, the battery drain went back to the usual 2-3% per hour on standby.
I am running stock LQ3 and stock kernel. I am rooted, as I have flashed it through Mobile ODIN, over stock, rooted LPY.
I have quite a lot sync-accounts - twitter, facebook, gmail, email, weather widget etc. so I am quite used to relatively short battery life but the trick with the headphones came as quite a surprise.
Before writing this post I decided to test it today as well and it is the same.
So, could someone test this and report? I think that if this proves to be true and common, the devs could easily track what's happening exactly and sort things out, so that battery can live longer without the headphones plugged in.

Ugh...I am terribly sorry, this was meant for the General Discussion. Please, admin, move it there.

I've noticed that same if the SAR of the last samsung mobile is very low, the reception is quite good compared to other phones.
Do you notice also an improvement of the signal reception? Because if it is the case, it is that your headphones are used as a secondary antenna, giving the phone a stronger reception and less power consumption (better signal = less need of power usage for processing the signal)
This is just a theory...

After some ICS ROMs I went back to Gingerbread, mainly due to poor battery life.
When Litening ROM 2.0 was published I flashed that one. I liked the GB version a lot. The battery life was remarkable, a lot better than previous ICS ROMs. Because Litening is not much supported I tried Alba, also LQ3. A surprise because battery life was the same. I think I'll stick to ICS this time.

Alba often uses LB2 modem (from GB) in his ROMs - maybe it is the reason. I myself observed huge batterey drain on latest ICS ROMs while connected to Wi-Fi at my workplace. Fixed it by flashing ZCLP5 modem (from early "LP5 leak" ROM).

Hm, that is an interesting theory. I am not sure, however, that the headphones' cable really improves GSM radio reception. I think it is only for FM reception. Of course I have no knowledge behind that, just thinking.
I have frozen lots or apps in Titanuim Backup like:
- the whole range of SNS's
- Social Hub
- Wi-fi sharing manager
- the infamous wssyncmlnps
- software update service, etc
Also I have stopped a bunch of receivers, using Autorun Manager Pro, and disabled a lot of processes from Autostarts.
This should mean that I have opted out the most common battery drainers. I have tried to disable auto-sync for the time being, but that does not seem to be much of a drainer, so maybe the real problem comes somewhere from the modem.

Hey dimcus, i've been having this WiFi vs battery issues with some routers(including the one at home), weird enough it doesn't happen on some of them. I did read somewhere about flashing te Modem file, what leads me to a couple of questions ir you don't mind. Are you on ICS? Do i need to be root to flash the Modem file? If not, any risks involved? I'm on stock ICS LPY DBT.
Thanks in advance,
VR

I flashed the ZCLP6 modem earlier today, guessing that it would be better than ZCLP5.
It is too early to judge but first impressions are that maybe there is a slight improvement in battery on 3G but not something worth it over the stock XXLPT that I used to have and generally battery drain on wifi seems as bad as it has been ever since I flashed ICS.
I have read that some people dared to wipe their Notes and after that most of the problems had disappeared but I don't want to risk getting some brick.
I will try several other popular modems and will report back.

Please let us know how you get on with them. Currently on LR1 modem and noticing a few strange wakelocks.

I have been with LR1 modem for about 40 hours now. What is better than the ones before is the much better behaviour on wi-fi. Other than that it is hard to tell any differences. So far 7 hours since unplugged, 1 h screen-on, half time wifi, half time 3g - battery is at 75%

wow.. that;s great.. i upgraded to ICS 5 days ago.. super poor battery..
then I heard to go with speedmod kernel, which I did.
no change..
Can you'se tell HOW TO change the modem?? I need to do something... mine just dont last worth a crap.. half day..
should I try a modem? and can you please say how to do just the modem??.
my baseband is N7000XXLPT
and build # is IML74K.XXLPY
thank you!

Unfortunately after several different ICS Roms (From Stock LPY to Cleanote 2.20) with several different Kernels (Stock, SpeedMod, Goku and more) and few modems (XXLPT, ZCLP5) I had to go back to Ginger due to extremely poor battery life. With all roms /kernels/modems combination the behavior was very similar. The phone was going into deep sleep pretty easily when idle with very low battery drain. On the other hand when using the phone I was getting about 10% drain each 20 minutes (A little less with data wifi and all sync off). I was also getting overheating with temp most of the times over 40 deg C. This drain was almost the same even with system energy savings on. I could not understand the reason for this strange behavior considering that many other users are having great battery life on ICS with their devices. Anyone is experiencing this situation ? NB now with Ginger the battery life is ok.

^ I experience same behaviors...

Hi
Do you by any chance have a German Note ? Mine is German and I was wondering if all the German notes had the same behaviour ..
Thanks

Battery drain with cm10 paranoid android
I am facing a huge battery drain issue. Used the phone for downloading and playing games and general usage yesterday and battery only lasted 3.5 Hours. Need to continuously watch the battery as it drops about 10-20% on idle. Checked the wakelocks and mainly wifi related, the phone is going into deep sleep just fine. HELP PLEASE!!!

lol continuously watching means you're the wake lock.
btw phone only has 3-3.5 hour screen on time. When playing games its usually less.
All do some reading into analyzing battery life betterbatterystats and cpu spy

[Q] How to fix fake battery states on almost all roms?

When i switch another rom, every time my battery draining is terrible so i think this is the battery states fault.
Anyone tell me what is the better way to fix this issue?

What do you mean?
It's normal for a rom to use more battery the first time you use it. Besides that there is no such thing as a fake battery state.

Ok sir
I use amlify, freenify, and boot manager but...
After 3 days using this rom or every CM based rom i lost 25% of battery on 7 hour without using my device.
Sorry for my bad english.

...and?
battery life will decrease when not in use, this happens to ALL phones or electrical devices that use a battery

well obviously everything that is not plugged-in , on the electricity needs power to run, but i think you lost the point of his message,
i think he means that 25% is a lot, for a phone in no use.

I lose more with data on. I think it's normal result for 7 hours.

Custom ROMs need a "settling in" period where the software polls the hardware for its capabilities. The OP may simply be impatient and expecting instant benefits from the ROM without giving it a chance to adjust itself to the hardware. 25% in 7 hours is typical for someone not using Greenify, but it's arguably high for someone using that app. If the OP isn't being impatient, it makes me wonder how old the OP's battery is, since a new battery shouldn't be having this much drain.
The OP would greatly benefit from updating to an Android 6 ROM. In situations where the phone is simply sitting there, Doze kicks Greenify's a** all over the park.
