battery life?

Hey guys,
Quick ?. On my wing, with the stock tmo rom, the battery life is awesome, when I run the herald 6.1 rom, it goes to crap, I have to charge it every day.. Is the 6.5 any better? Or, what would you suggest?

I only used 6.5 for a few days, but from my observation, it's not getting any better in battery life. It may got worse since more cpu intensive. In theory and from my experience, 6.1 and the stock rom should have similar battery life. It might be your rom. Some roms (not to attack the cooks, do get angry at me) may have bugs the kill battery faster than others. So my recommendation is to try another rom. A clean one always best. Another thing to try is to use homescreen++'s dynamic cpu scaling. Could save you some battery to under-clock for non-essential time. Someone says this helps and some says no. So try it and have fun.

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%

[Q] Which ROM

Hi
It has been a long time since I have visited XDA. I am still new to custom ROMs. I installed VR12 with a lot of help from fellow members about a year ago. I am now looking for a change of ROMs. I do not use facebook, twitter, stocks, gmail etc. I basically use my Hero as a normal phone and approx 1 hour internet a day (Opera mini). I am trying to find a balance between speed and battery life. I am not too fussed with sense. I am not up to speed with current roms. I am basically after a reliable fast rom with good battery life. I want to try a ROM without sense. Is a rom without sense better on battery life?
Any feedback is appreciated
Regards,
Riyaz

If you want speed, go Vanilla Eclair. It's just awesome Batterylife is really good as well, many people report better batterylife on this one than on the newer one, though I get a bit better on Froyo roms. Installing Juice Defender can greatly increase your battery time. If you want a newer rom, I recommend Elelinux Speedmachine but nothing comes near VE in speed and performance

try VR13 also...it's very fast. When you go from sense to a stock rom you get a kick because you get used to some features and sometimes miss them... You can also try a GB rom an d see how it works.

[Q] small newbie questions

I hate to make a thread like this, but it seems that this is kinda of those "everyone already knows this" or similar question that does not get brought up.
Anyway:
I decided to revert from genokolar's CM7 to stock Froyo firmware (functionality and hopefully battery life reasons, just one was enough of reason)
I found a update firmware in huawei's site for 2.2.2 Froyo, it was two apps in dload folder I had to boot into volume up+down+power boot mode, prior to this I had wiped EVERYTHING I could in clockworkmod, and after the update and few reboots, the system seems to be in working order. Even my recovery image is replaced with stock one now.
I know the CM7 port in question had some kernel modifications - especially ones affecting to CPU clocks, that in hand may be stuff affecting battery in negative way, and also imposing possible problems with stock system - does the stock 2.2.2 update also write in the stock kernel? If yes, thank you, I will be relieved. if not, then I need to figure some back plan.
P.s. waiting official gingerbread as is everyone else. Bug reports from many people about the official beta was one reason I went to stock froyo for now.
Thanks!

Yes it does. Or it has for me.

If I understand you correctly, you got worse battery-life with CM7 than you had with stock firmware?
I nearly doubled the battery-life going from stock f/w to oxygen, right now on MIUI and on my second day without charging

Thanks. If so I then do not need to find way to install the kernel from huawei downloads just to know will the battery life increase.

Well, It is combination of functional issues, general feel that the system may not work like intended, and to experiment will the battery life increase. Generally I looked the ROM selection for while but there seemed to be quite wide array of bug reports for each what I did not want to buy into. Unless there is some widely accepted strong recommendation for system - thanks for the input though.

Battery life can have a huge difference between phones. Also how much you use it has effect. I have better battery life in stock too i have used all rom except the new ics ones.

Yeah, from tests I hear if something, battery life in Hussein is quite great, at least in stock manner.
And my first problem basically was first night after installing CM7 and leaving phone, screen off idle, not charging, and during that 6 or so hours of idle, with wifi and connections turned off, my battery had been drained to half when I woke up and checked the clock.
Thanks tho. Not to say the ROM development are bad, opposite, they bring what people want, and already done better work at customized gingerbread builds for this device than Hussein with their betas. To me the battery life just is more crucial than the features of both 2.3 and the customized ROM.
also, thanks.
