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%

Battery life decreasing...

Ok, so I've had my SGN for little under a month for the first few weeks I had it I was getting great battery life, almost 6 hours screen time full day of battery etc.. Then I rooted it using one click root because I wanted some more access, since then battery life has seemingly been slowly getting worse. I have tried changing back to stock roms and custom roms, I've fully discharged the battery and charged while it is off a number of times but I'm down to 3 hours screen time and can't get a full day out off it anymore.
Is this something to do with the way I rooted, what can I do test and try and get back my battery life, this is the main reason I got this phone..
It's hard to say if it was the first update I installed/rooting or something wrong with the way I'm charging but it's certainly decreased even on a stock ROM without installing anything..
Anybody else encountered this?

Check battery stats and show us a print screen

Going to try latest firmware and just bought Odin mobile.. Hoping that'll fix it.
Won't let me add a picture says I don't have permission.. Sigh.

I have the same "feeling" with my Note. I have installed System Panel to monitor usage but I can't find anything specific that seems to be sucking the power. But it certainly "feels" like my battery is draining faster than before.

It's probably as the phone gets older, you install more & more Apps. Some of these are probably working in the background sucking your battery.

Even with a clean stock rom, it doesn't seem as good as it was without root or any updates.. Wish I remembered what the phone came loaded with, I'd give that a go..

Try Rocket Rom v17 or latest XXLA1 firmware and your battery life will come back even better than before, just me

Same "feeling" here! I will try LA1 firmware....

So I'm currently sitting on 4.30 hours screen time, 15 hours uptime with 20% battery remaining.
Running la1 firmware and la3 modem, been using stock browser. Taking lots of photos with flash too, so I think this combo has rectified my issues but I know there's more potential as this is roughly the same stats I got on my dhd, although that was underclocked and tweaked to the clappers.
Faith is resetored in my device, hopefully it improves.

[Q] Insane Drain after 35% of battery

Phone is 1 and half month old, this problem is persistent from the start.
Insane drain even without usage after 35%.
35% to 1% in 30mins approx with light or even no usage.
I've tried different roms, Xnote, and CivZ kernel on 4.3 but no avail.
Now I'm on stock KK and same problem here.
Anyone else having the same issue ?
Most of the apps greenified, and heavy debloated with Titanium.
Best Screen on time I got was 4.5 hours. and mostly I get 3hours with moderate to low usage.

Can I flash lean kernel on Stock 4.4.2 rom ?
I had unknown baseband problem after flashing Xnote rom. So hesitating on flashing roms now.

I've Strange problem with battery
Battery was normal even more so I was very satisfied with it until I turned it off to a 3-4 days I used it, because I tried some LG. battery was full, so I turned it off took out the SIM and put it in the LG, after this battery can not put in place any day soon now and fills and empties. What could have happened in those few days?

Nexus 6p stand by battery life on pure nexus

Hello everyone , hope y'all doin good.
I got a question. I got my 6p a new rom , purenexus... Flashed a new kernel (elementalx). I did it yesterday , but today morning , I woke up , on 100% , unplug my phone , put it on my pocket and 2 hours latter , I had like 96%. This is a massive decrease over stock Android when it came outta the box. Can someone tell me if this is normal or not , or what shall I do to get the impressive 1 month on stand by that I had (phone was on 70% , broke the screen , didn't touch it , repaired it , when I turned it back on , it was on 37% , for a whole month+). What shall I do to get the best outta stand by time ?

Get pure nexus Jan 21st build flash Franco then apply wingoku profile 2.1 with ex kernel manager and you'll be flying with the best battery life

Check your battery capacity with Accubattery. Run it a few times. Your battery may be degraded like many other ppl out there. To rule out the ROM itself, flash stock and compare.

Everything with the battery is ok , just got to get a good standby time , does anyone has any tips ?

Well, how many apps have you installed I the last 24 hours? Maybe all your apps are optimizing possibly?
What do you have running?
Any chance you were playing music?
Did the phone have a y heat to it when you took it out your pocket?
Also... I always felt that the first 1-5% goes really fast.

Ha Ha, what is your measured capacity with Accubattery? Probably thousands of ppl are having degraded battery problems. If you are looking for a limited PN fanboy response, why not just post in the dedicated PN sub-forum? You have a battery drain problem but apparently don't want to run a battery diagnostic to find out where the problem really lies, or flash to stock and find out if your custom ROM is the cause. A "tip" is not going to cure your problem. It requires homework.
Edit: Another issue is that the 6P is inaccurate at reporting 100% charging. Your device may charge for up to an hour longer to actually be full on the stock charger after showing 100%. What you see as fully charged may not be.

I left Pure Nexus because battery life was very poor compared to stock and Cortex. I thought it might stabilize after a couple days but the poor battery life was a constant and I was not the only person having that issue. I was running PN with Flash Kernel and Flash's profile. You will get better battery life with Franco Kernel but with noticable negative effect on the performance of your phone. You could always try Francos Naptime app which puts your phone into deep doze as soon as the screen goes off but I didn't personally care for the app. You might want to consider a different Rom if battery life is very concerning to you. I'm currently on Dirty Unicorns with Flash Kernel and I'm getting better battery life than Pure Nexus but not as good as Cortex. The problem with Cortex is that you have to use Flash Kernel to get good battery life and there is no OMS support. When Substratum stopped working in Legacy Mode (again) I decided to switch to a Rom with OMS support.

About battery SM-N910U

Hi, i have SM-N910U device and the original new battery. But, why my battery draining so fast? Currently i using MM 6.0.1 official. Not rooted device. I’ve done lot of things to keep battery stable. But it seems not working. The battery drained so fast. This is malfunctioned of seri U or what? Thanks for the answer

What do you mean by "original new battery"? Do you mean the original battery that came with the phone? Or you have recently purchased an "original new battery"?
If you have recently purchased a battery it is almost guaranteed not to be an original Samsung battery as they do not make them any more - it is probably fake. Buy a RavPower battery and see how it goes. Same if you're still using the battery that originally came with the phone - get a RavPower. You might also want to try a factory reset and set your phone up clean again - this made a big difference to mine about a year ago when my battery was draining fast.

Three possible curlpits: Your apps, the battery, or the firmware
Battery—fake battery will die fast, according to what others say
Apps—some apps are battery hungry, so find a way to hibernate those with Greenify or Hibernation Manager
Software—Android 6 is the last and worst update for performance and battery life. While it's on KitKat (4.4), its battery life was awesome; fast forward to Lollipop (5.0.1–5.1.1), from 12 hours of Screen On Time (SOT), it got decreased to 8 hours; and fast forward again to Marshmallow (6.0.1), it became from 8 hours to 3 hours. No matter what kernel or battery-saving methods you use, it's futile for a firmware that rots a powerful phone. The only way to fix this is by either using a custom ROM (Refined Nougat, Note 5/7 ported ROMs, etc.), or downgrading your firmware. (Installing KitKat with the latest bootloader prevents you from downgrading).

With a new battery on MM stock and unrooted I was getting 6 hours SOT (Exynos). Dropped off now after using the battery for 18 months, but soon upgrading to Note 9 or 10 anyway.
