cyanogen six sucks the battery life

My battery life on cyanogen six is down right awful. Every day I charge it at night and when I go to bed even if I don't use it its at 15%
Isn't there anything I can do?

I, as well, see about a 1%/hour drain when my phone is not in use.
Usually, unruly battery drain is due to a rouge application you have installed.

I'm getting better than ever battery life on CM6.
Try charging all the way, reboot into recovery, wipe battery stats, charge all the way again.

I did something similar... I got it to warning (15%) and then erased battery stats... I then ran my my phone until it died and died again... after that it shouldn't get past boot if so then proceed to boot it into bootloader. The bootloaders white screen should drain back up battery quickly so only leave it on for only 2-3 mins. Charge it fully powered off and enjoy 15+ hours uptime!

my battery sucks ass too it was never like this before??? kernel??? could a different kernel fix this issue..if so which is the best please be specific so many kernel to choose if any...please help..thanks!
does the phone radio matter because im using the 5.8.4 i believe..

cyan 6 has had terrible battery life for me. so i switched back to leofroyo latest beta rom and got back my 3hr/% standby battery life. with widgets and email checking every 30 minutes. i'm down to 2hr/% in standby. usually in a day i lose 25% battery life with mild internet use and calling. i charge my phone every two days. can't beat that.

Try manually closing all applications & services that are not vital to your phone, then test over a day or two. If that doesn't work, try a different kernel.

Okay I've had about enough of this. It goes down to 15% every day EVEN IF I DON'T USE IT AT ALL
Could someone recommend me the best battery life rom in town, even if it's the stock one?

This one is good. Best in town is hard to judge, but a lot of people enjoy the battery and stability:

Try blackbar v6.1 or stockbar v6.1. Those are the FRF91 build. I haven't tried the FRG33 but it's probably pretty great as well. The first post lists the changes from stock.

I'm fighting with battery life too, but problem is not when in standby where it uses less than 1% per hour, but actually using it (browsing) you can see battery lose 1% every two minutes... is it like that for you guys also? Really frustrating me...

Don't do this. Draining lithium ion batteries to completely dead is one off the worst things you can do to those batteries. It kills off their capacity
Charge to full, turn off phone and charge again until led turns green again, then boot into recovery and wipe battery stats.
15 hour uptime is average not excellent

This is an excellent ROM. i've used it until i switched over to LeoFroyo. They both use the stock kernel and in my opinion i think its th best.
i also like to downclock the processor down to 800mhz with setcpu. definitely helps with the battery drain while using the phone. Non of those 925mv kernels help out in my experience.

Well I run go chat and msn constantly, I use 40 percent display, wifi, 3g, sync, etc and its about double the length I got when it was stock. Right now at 12% and I'm at 16 hours and 32 minutes! I wipe battery stats every time I flash a new radio also it seems to help

This is way better battery life than what I get on Enom's, but I get consistantly 14hours to about 15% and I use my phone a LOT.

Really eh... Well il be sure to check out some new enoms! I'm feeling this nxsense too 13 hour first day not bad for porky sense

Heavy for me means more than 3 hours on the screen being on... as im constantly using my nexus... i just cant put the thing down for a min.. and yeap enom's rom with wildmonks kernel really helps the battery..

battery problem kyrillos Rom

i use the latest release, 3.3 version and my battery drains in like 10 hrs of normal usage...
the worst part is that upto 95% of battery is consumed just by display?
i used to get 2 days of battery backup previously on the official Rom.
i tried re flashing kyrillos Rom yesterday and i still get the same problem :’(
is there something i am missing?
or should i wait for atleast 1 week after flashing?

I don't know, but you can also install Juice devender from the market
I like that app. Now the battery has a longer life: 2 days.

The battery seems to be a problem indeed with our devices. Mine was on 5% for 12hrs yesterday.
I've read advice from Lestat, I think, to charge the battery completely before flashing.
I've yet to test it though.

awesome bro, will reply here with the results soon......

does some1 know a fix to show my battery in units in stead of dozens? srry for my english^^

boom....battery at 60%, 25 hours and still.running ( but can only say its because of this when i get home....because right now my cell phone is in airplane mode)

thanks
i think i know why i am loosing battery very fast

It may have to do with cpu scaling also.I installed cpu master and saw that the cpu is always on 667mhz and not down-scaling when not in use.
Kyrillos 3.3 rom

try using SetCPU...

clarkkov said:
This depends on the network you use, but you can set your phone to use only GSM network or only WCDMA network in the Mobile network settings, if you are located in area where your network switches constantly because of a weak signal your battery will drain itself because of constant refreshing and switching between GSM and WCDMA networks. WCDMA (3G) network uses more battery even if not switching.

Thanks, mine is set to GSM only, since i don't use 3G..
I tested my phone again now for the past two days and found out that it comes for like 20-24 hrs in moderate (daily usage), which is ok for me....
the battery first reduces to 80% in the first 1 hour (even with minimum usage, don't know why this happens), and then it stays at 80-60% for like 15-16 hrs...

I got this problem in Kyrillos 3.0beta version...but now in 3.3 its fine...i can use mine till 2.5 days...widout task manager!!! :-/ i dunno...!!! Juicedefender works cool for sum ppl!!!! the oder solution try Indroid 3.0 - it has better battery backup!

clarkkov said:
You should callibrate your battery with one of the callibration apps, or charge to 100% and then delete battery stats file manualy. Then discarge your battery completely so the phone switches off. The next cycle should be better. Those first 20% percent do go faster than the rest of the battery.

true , true, true thanks for confirming

still 30 hours isnt enough, its roughly a day.
With 2.1 original firmware and data activated all day i could get 50hrs minimum of battery life.
I'm done with this phone, done trying different roms, calibrating batteries, charging and discharges in less than a day.
i think this phone rocks, except its battery life sucks!
im selling it to change for something with better battery, maybe bb?

Battery problems is from ext4! You can convert all partitions to ext2 with normal battery life but with more chances for data to lost if you remove the battery!

[Q] Concerning Overclocking

I think I've finally gotten a good grip on this Nook stuff, a million thanks to everyone here.
My Nook is where I want it to be currently with the latest CM7 stable.
It seems like everyone is overclocking and now I'm curious.
Do you guys keep the overclock on the entire time you're using the nook? Or do you turn it on when you need the extra performance?
Does it shorten the battery life by much?
Is it harmful at all to the hardware?

Good questions. Overclocking is, on the surpface, something one would imagine harms our toys. Actually, most can handle well. It's all about the voltage and not so much anything else. Dal and others have worked out the tough stuff and provided us with some extremely useful kernals that noticably increase speeds (demonstrable with apps like Quadrant Standard or Smartbench) Apps run quicker and the overall experience is sweeter. Ondemand is the usual govenor I employ set on boot. (Running CM7.0.2 1.1 OC) Still getting a full day of use before recharging.

Usually it only kicks up to overclocked speeds when it needs it, cm7 can regulate it's clock speed pretty well depending on what setting you use.
technically overclocking will slightly shorten the life of the processor (uses more power, produces more heat). It doesn't really matter though as my battery will give out long before my processor, regardless of whether i overclock or not.
By that time i'll probably be thinking about buying the sweet new nook color 4 anyhow.

I have one of the handfull of Nook's that can run at 1.3 GHz, although I have it set to boot at 1.2 GHz to eliminate the occasional bootloop from trying to load up at max speed. Once booted I kick it back up to 1.3 GHz and leave it. My battery generally lasts 48 hours of light / moderate use with the display being the single biggest power hog.

48 hours of using seems impossible to me when I use my NOOK at work for FB and some little gaming (not 3D) and after 8 hours is at 50% of battery.
I use daily 300/1300 at On Demand and never had any problems with device.
Extra heat is harmful.So if the device isnt get so hot, then things are ok.

You're right 48 hours of use is impossible. To clarify.... I'm usually off the charger for about 48 hours... not 48 hours of use. I'm 20 hours off charger now, wifi running about 10 hours, screen on for 2 hours 24 minutes and battery at 53%.

When does the battery meter reset? Is it when you charge the battery back up to 100%?
I just got CM7 working and haven't had a chance to go through the entire battery yet but based on what I've seen so far I can maybe squeeze out 5-6 continuous hours of usage, does that sound reasonable?
Based on what I see it's significantly hungrier than the stock.

Depending always on what U do during usage (different to play games or just browsing the internet), U should really have the hours U propose.
Soon the problem with the sleep will be solved and the autonomy will be back to normal.

For everyone with battery drain issues

You need to run this app every time you flash a new rom to correct your batterystats.bin file. The batterystats is what dictates how long your phone should be on from the battery. This app deletes the .bin and allows it to be replaced thus conditioning your battery like you were supposed to do when you got the phone. Note: Doing this too many times without flashing a rom or without severe battery drain issues CAN shorten the life of your battery (I know from experience) So please don't do something stupid.
Instructions: Charge to 100%, Run the battery calibration, allow to die COMPLETELY and then recharge to a full 100% (no trickle charging)

You shouldn't need an SBC kernel if you are planning on doing this. However it should still work, just make sure it's at a full 100% oh and also, SBC damages your battery after prolonged use.

So we should not get a 10% battery drain from unplugging this if we do this correctly? or this will just prolong the battery life from 90-94% on after unplugging??
I've tried doing this but never 100% fully let it drain and then charged 100% lol...
And do you charge while phone is off? wait until green light comes on?

I'm still getting terrible battery life. 25% drained in 1 hour, and it's just idle with the display on at 50% and wifi/data connection enabled. I have a static background image and I don't have any fancy widgets or anything.
To give more detail, I'm running Synergy RLS-1 (no godmode) with aggressive freedom kernel. I have SetCPU with min/max 128/883.

Well, its going to be a quick drain until a few charge cycles ii got 24 percent drain in 2 hours then it leveled off for me.
Going on 18 hours of battery life if not more right now, I think this works since before, I only had 8-10 hours of moderate use.

I do all of this while the phone is on just to be sure there are no false stats entered. But I'm sure you can charge while it's off.

Update on my battery life: It's probably going to be roughly 19 hours until it dies. 7% and I have 18h 35m 17s So this shows that this works undoubtedly if done correctly.

Is it going to gradually increase with each charge cycle, or am I going to notice a big change eventually? I'm on my second cycle (after calibration) and it's still draining like mad. :\

I went a full 19 hours so you should notice a large change eventually if not, I think your battery might be bad?

Alright. I hope that's not the case!

I bet if I took a poll on here the overwhelming majority of people would click "no" to:

Doesn't mean it doesn't happen.
The mere suggestion that because something hasn't happened to you, or that some online poll says it hasn't happened so it must not, is absurd. At best.
No, I'm not suggesting that SBC kernels cause phones to explode.
But there's a lot of data supporting the idea that they can cause long term damage.
Battery's are not supposed to be filled and kept at their maximum for a reason.
And that reason isn't because the manufacturer wants your battery to drop to 90% as soon as you take it off the charger.

Lollipop battery issues

Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)
Sent from my LG-D320n using Tapatalk

Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).

Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

Wake lock doesnt find anything strange. Even twrp battery indicator in my custom recovery experiences the same effects

Ok ive done it a few more times and it seems to possibly be a calibration issue. But ive calibrated it multiple times before

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre

on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
