[Q] cogition 2.4.1 battery

im running cog 2.4.1 and it seems the battery drains fast i love the rom but what can i do to make the battery life better

Best solution is lower your CPU by using set CPU in the market is like 3 bucks but I found underclocking my CPU works really good. Is not going to save you tons of batterly life but works. Also I notice when the Phone is actualy cold your battery doesnt drain as much

Problem shoot
Did you flash at 100%?
Did you take you sim out when you flashed?
Have you tried a battery calibration?
I think the battery on this version s on par with previous.
Captivate
Cog 2.4

no i didnt take out my sim card should reflash it with my sim card out

and i dont know how to do battery calibration

I do not think you have to reflash unless you encounter some additional bugs. It is recommended that you remove your sim prior to flash. Some say it can effect battery
Calibration
Charge phone while on till 100%
Unplug and turn off
Once it is completely off plug back in charge till 100%. Volume ticker brings up battery display
Power on and let phone completely boot.
Power off plug back in once off charge till 100%
While off hold volume up and down and power till at&t screen comes on. Let go. You should be in stock recovery.
Click reinstall packages to get to clockwork recovery. Go to advanced then wipe battery stats. Reboot phone
Run phone until it dies with zero power. Charge while off till it hits 100%
Captivate
Cog 2.4

i dont think when i flashed it the battery was a 100% is that a problem

That's not a solution. That's a workaround. He's implying that his battery is draining faster with 2.4.1 than other ROMs/versions. That's like complaining that someone is hitting your head with a hammer, and instead of getting rid of the person/hammer, you put on a helmet.
Also, using SetCPU with a Captivate varies greatly upon usage.
SetCPU doesn't handle minimum CPU speeds even remotely as well as normal system settings, thus you may have a lower maximum frequency (and thus consumption) but a significantly higher minimum frequency (and proportionately higher consumption). So if you're using your phone at 100% capacity 100% of the time, then sure, SetCPU would work great, but for any realistic usage, your mileage will vary.

It shouldn't be a big problem, or at least, not a problem that recharging to full then clearing battery stats while it is full like others suggested wouldn't solve.

well ok thanks guys im going to try the battery calibration i hope it works cuz this rom is freaking awesome

The point in calibrating the battery is so that your phone. Knows what a true 100% charge and a full drain means. When you flash especially when your battery is not fully charged the phone may tell you that there is a full charge when you actually only have 80%. So obviously you battery appears to drain faster. This does not make your battery a super battery, just gives you a true reading

[Q] NC discharges quickly while on standby CM7/Stock1.01...

Hey guys,
I'm experiencing rapid battery discharge while Nook Color is in standby mode, battery life used to be great while on standby but after using CM7 on sdcard it's nearly discharges like when it's fully working...
Any ideas?
Thanks in advance!

sounds like your battery maybe on its death throws.. or perhaps you have too many background processes suckin up juice.. we need more info to be helpful

Reboot without card in and check stock performance. They shouldn't affect each other. Plus CM should have better battery life very soon.

Are you running the performance governor? this would keep your CPU at max ALL the time. if you are try switching to Interactive.

Does anybody know how the batter performance in standby mode for CM7.0.2 compares with stock?
Could you tell me when when the CM7 battery tweaks are coming?
Also, could somebody tell me how to maximize battery time when using Nook?
Lots of questions! Thanks in advance.

I was on cm7 but the battery drain was an issue for me. There is no fix currently but the awesome folks at the cm7 team are supposedly going to iron this out soon. Stock should last at least twice as long on standby.
If you use the nook mostly at home I would lower the display brightness all the way down, and completely shutdown at night.

Assuming not overclocked, in use CM7 is very similar to the stock ROM because the screen and backlight are taking most of the power.
In standby the stock ROM is around .2%/hr with wifi off. CM7 is around 1%/hr with wifi off.

I have CM7 nightly build 55 on my Nook and the battery life is amazing.
Besides the feedback others suggested, check to see if you have things actively running in the background. Is the setting to keep Wifi on in standby turned on? That could do it. Do you have some funky mail client on their set to check every 5 minutes or something?
I think the best suggestion was the one previously about taking the SD card out and run it as stock to see how the battery life compares. If it is fine with stock, then you know something goofy is going on with your CM7 install and I would just start over on that with the newest nightly, etc.

My batt stats say Phone idle and Cell Standby are 22% and 17 % over a 12 hr period. So those are what are killing me and the NC isn't even a phone.

Battery performance even on overclocked nootered 1.2 Nook Color is great. I am getting drain of less than 0.2% compare to closer to 2% on cm7.
This is due to cm7 not having full sleep.

Thanks for your reply Canadoc!
Do you know how Stock 1.2 ROM's battery performance compares to that of Nook Froyo 0.6.8 R7 ROM?

[Q] ROM with best battery life

I'm searching for custom ROM that has at least a decent battery life.
I'm on Darky's v10.1, but I'm getting Android OS bug very often (and then battery lasts for 5-6 hours), and when I'm not, battery life is around 10-12 hours. I'm pretty annoyed that my battery can't last for whole day and I'm looking for ROM that will give me at least 16 hours of battery life. Also it's preffered that ROM is pretty fast too. Thank you

Try XWJSD, the latest 2.2.1 firmware. Batery life is prety good and it is the fastest froyo so far. On my phone about 35 hours on normal usage..

Oh, I would like to have Gingerbread firmware, I don't feel like degrading my phone back to froyo :/

That's strange cos I'm on Darky's v10.1 and it's the best I've found so far. Battery is lasting me about 16 hrs on average, depending on what I use it for. Day to day use of calls, lots of texts, some internet and some pics can see 16hrs.
There is always this option: http://cgi.ebay.co.uk/1930mAh-REPLACEMENT-BATTERY-SAMSUNG-I9000-GALAXY-S-/250807245269?pt=LH_DefaultDomain_3&hash=item3a6546d9d5

Well, I guess it depends on what you use it for - but it's not enough for me. And I heard this battery isn't making much difference...

Ok, thanks for letting me know about the battery replacement. I was considering one of them for myself

Hey, unsure if this will interest you or not, but I use Juice Defender ultimate and it is absolutely amazing!
Depending on your usage (much of the time my phone is idling) and whatever settings you set, this app will make your battery last a very long time.
I've just check my phone's battery usage and after 15 hours I'm still on 78% battery.
Obviously these figures would change dramatically with more usage but just thought there wasn't any harm in letting you know about it if you didn't already know. 8)
PS: I'm using Darky's ROM v10.1.

I have the following ROM and battery consumption is very low. Try it and comment.
PDA: I9000XWJVH
Phone: I9000BUJV3 from BUJV9.
CSC: I9000OXAJVK
KERNEL :Voodoo test 6.0 de supercurio.
If you prefer, you can change the CSC file for another.
Greetings.

juwe's rom,always wifi on, with aggressive use more than 1 day,
moderate use 2 days
only calls and sms more than 2 and a half day!

try "Advance task killer" app
keep it to stop all program when screen off
and you will see the battery, better than before

What would you do when ...

hi all ,
my phone is having some battery drain issues ...when i use GXP v22 the battery drain 1% everty minute in standby ..no battery in just 2 hours with GDX it last only 10hours
even when i full wiped , clear dalvik , wipe battery stats the battery still dies to quickly ...
so what would you do?
oh ya i got this rather odd problem the battery went standby for about 4hours ..the battery was 75% and still is ..but then when you use like 1 minute it drop another 1% ..why?
will the launcher be he culprit? i use launcher 360 ..
i off everthing , 3g ,0% brightness , no haptic , no wifi , no bluetooth use silent etc...

flash the other rom after flashing gdx without full wipe.. hope it works ...

Try another "Rom" i guess it's not the launcher but the rom itself, try XGin 6.2 it has a great batt. life. been using it for over 2 weeks now and i'm pretty happy with the battery life.
wifi always on, calling, texting, media streaming, brightness set @ 70%, surfing and my batt last for about 1day 7hrs..

will it help if i give it some time ? maybe a week or 2 ?

I don´t think so.
But that battery drain IS NOT NORMAL, I normally get beetween 24h and 48h of without charging, sometimes even more, and less when I use Wi-Fi or play 3D games.
There´s a battery calibration app on the market:
You charge you phone, an when it´s at 100% you click a button and then the app wipes your battery stats.
You can also set an alarm that rings when the battery is on 100%.

GingerDX v022 on Stock Kernel, smartass governor (default scaling values of 122->600 MHz)
With WiFi and 3G turned OFF the battery drain is 1% in ~2.5-3 hours (phone idle).
With 3G turned on and WiFi turned off the battery drain (almost full reception) is 1% every 4.5 minutes!!! (~7 hours before the battery dies)
With WiFi turned on and 3G turned off the battery drain is 1% every 15-20 minutes (phone just sitting there causing the usual traffic of Gmail, Talk, Sync).
Try to set your phone to a comparable configuration (no idea if GXP has a CPU Governor setting - in GDX it's in CyanogenMod Settings) and try to replicate the test ...
From the "with GDX it last only 10hours" you wrote it sounds like your phone is constantly connected to WiFi or 3G (and maybe having download/upload traffic going on - therefore increasing the power consumption).
EDIT:
Also note that overclocking (as I recall I spotted a overclock thread of yours) will chew the juice out of your battery at a way faster pace.
Keep in mind that the values may differ depending on the GSM/3G reception ... the weaker the signal, the more power the phone needs to apply to communicate with the tower. If you're in an area where the reception is poor you shouldn't wonder about the battery getting eaten.
As a last resort, keep an eye on what applications you have running in the background. The more crap you got running, the more bat drain you're going to have when processes are fighting over CPU time.

NONO i never on wifi / 3G / bluetooth / GPS ..cause of the poor battery i tried my best to save as much battery as possible ...but in no use =( i cosntantly use task killers and i use smartass governer i think i will try stormvix ..oh! and starting my phone eats about 20% each time i does it ..is this normal?

i tried the battery calibration app ..doesn't do jack =(

should i pcc my phone? and redo everything

"starting my phone" translates into what ... ?
Turning it on (from being powered off) and letting it boot up results in 20% loss of battery charge?
That's NOT normal at all ... your charge should lose 1% at best if it was already close to going down by a percent.
Using the phone for a phone call makes it lose 20% battery charge?
Well, that entirely depends on the length of the call and the reception. Going down 20% would be about... hmmm... 1.5h talking time (estimated from the top of my head)?
At any rate ... a rapid loss of charge like your 10 hours while the phone just idles around twiddling thumbs and not being connected to WiFi or 2/3G is not normal no matter how you look at it. EDIT: Unless you overclock sky-high and running the performance governor which would keep the CPU fully clocked no matter what's currently going on.

starting in the sense like restarting eg entering cwm / xrec ...i flashed back to stock now ...gonna do it all again .. i knew this was too much drain i off everything even background data and i use smaratss 122 - 710 , even my brightness is 9% ...

Just for testing purposes to see if the bat drain stays within a sane stretch I recommend you stay with 122-600MHz.
It would also help to install some app/widget that monitors the current clock of the CPU - just to see if there's something which keeps your CPU busy and therefore running at full throttle. I recently saw something like that, I just fail to remember where and what the name of the app was ...........

okay so i flashed to stock last night ..i on everything sync , wifi , bluetooth , data etc for 5 hours it drained only 10% surpisingly ...after 10seconds it restarted and dropped to 3% ..odd...and i fully charged my phone to 100% and left it there for about 1hour and it dropped from 100% - 86% ..any solution?

There are only two things left that I would consider ...
a) The circuitry monitoring the battery charge is bogus and pulling random values out of thin air (would indicate a hardware defect in the loading circuit on the motherboard).
b) Any change the guys who repaired your phone from the hard brick returned your device with a old, almost dead, battery instead of the shiny new one you had in your W8 that bricked (you know, shady retailers thinking to make a few extra bucks by selling off the battery of your dead phone as used-part replacement to earn a "little something extra")? This would closer match to the 10->3% / 100->86% jump symptoms - the battery being about dead and therefore unable to hold the charge and draining like wild.
I don't know which of these two options to favor, but I would give "b" a 51% chance over "a".
EDIT: Stay with the Stock ROM and complain with either the repair shop or SE as the drain problem can be reproduced any given time. This should actually be covered through warranty as the original phone wasn't that old, and the repair is somewhat unrelated. The battery should at least last for two years before you should observe major degrades.

[Q] CM10 battery life and other stuff

This is the first time I have flashed a custom ROM.I recently flashed the latest stable CM10 with the JB semaphore kernel and its been great so far as far as performance goes. But the main issue is the battery life, on moderate usage it seems to only last 10-12 hours. I tried the usual fixes like changing my modem, battery calibration and also making sure the com.media.process was not running continuously(using better battery stats app), and it seems to have slightly improved.
Questions are
1)Is this normal battery life to be expected from CM10?
2)Does CM9 have a better battery life than CM10?
3)Are there any other JB roms that will give me a somewhat bug-free plus high performance/good battery life?
4)Is the current stable CM9 more suited for everyday usage than CM10? I read that CM10 still has lots of bugs and issues?
Thanks in advance guys

My battery in JB lasts for maximum 10 hours

So there are no JB roms that have good battery life?

This is very important question for me, need to know witch ROM is better cm9 or cm10? battery draining extremely fast(8 hours aprx.)
Did someone tested this issue?

I'm not sure if I want to downgrade even if the battery life is better but I'm interested in this matter too.
Actually my only issue with JB battery life seem to be a rom issue ...

Yeah there is clearly something wrong with your installation. I am running CM10 Fishears Nightly, JB Semaphore 2.6.0 Old, XXJW4 radio and I usually have about 70% battery left at the end of a working day when I put my phone on the charger as I go to sleep. On a usual day, I listen to about 2hrs music on the train and do some light browsing/games throughout the day.
Here are my Semaphore settings:
Governor: Ondemand w/ Smooth UI enabled
Active scheduler: Simple I/O
Deep Idle Enabled
SAI Enabled
SD Card read ahead: 256KB
Normally the only apps that run in the background on my phone are:
BLN
Voodoo Sound
GO SMS
Settings
SwiftKey
WidgetLocker
Widgets
This way I don't have crap pulling my phone out of sleep all the time. On CM10 you should be able to get at least 2-3 days out of a single battery charge.

here my batterystatts i use stock cm10 with the newest nightly and the stock kernel sheduler noop govenor ondemand my 3g is enabled and i use more or less hole day wlan. i have the original battery.
