Hello,
Which one has longer battery life? From what I read, Chronos Froyo has longer battery life and also it's more responsive? Why is that?
Can CM6 use the same code as Chronos Froyo for speed and bat life?
I think it depends on overclocking.

I use HO!NO ROM for the CM6 and this weekend i realized that i was 22h without recharge it and was with 80% Battery. No profile set.. no Set CPU... Mobile Data 100% ON!!
I simply can´t understand, why every one has different battery life on same ROM. I know it depends on usage etc. but I´ve heard that HO!NO has huge battery drain
Battery performance is based on how one sets up his phone, overclocking, wifi / 3g usage, media usage etc. But on the same setup , cronos wins.
Ye, why Chronos is better? Isn't base on CM6 too? Or it has it's own modified kernel that's why it's better? Is bat life base on Kernel?

This is based on what exact versions being compared?
I have now tried Cronos for the sake of everyone prasing battery life. I compared every ROM over at least 3 days use and i can say there are no big ddifferences as far as battery life goes between CM 22.11. Froyo 2.0.1 or Cronos 1.6 update1. There is some fluctuation, but nothing too aperent.
Older versions had quite some battery problems, that holds for all ROMs, but now only abaut 20-30% less battery for me on these Froyo ROMs, than on eclair ROMs i had before. For first Froyo ROMs it was like 50% less...
Well, the CM6 on the actual build (0.04) is imho far the best concernig battery-life.
Just a little less good than on SHOLS_U2_36.0 by G.O.T.
Before it was probably Cronos, but nowadays the difference is down to the voltage selected. On Cronos this is lower, so out of the box it should take up less power. However, clock for clock it should essentially the same. The rapid releases of CM6 takes the cake for me
I tried both Cronos 1.6.1 and CM6 25/11, I noticed no great difference.. just a feeling, Cronos runs more smooth at same clock, but they are almost the same!

In my personal experience, Cronos 1.6.1 is currently the best ROM both in terms of battery life and responsivity/relayability. With everything enabled (3G, wireless location service, gmail sync) , is the only ROM that can give me 18 hours plus of battery.

Exactly. I believe both hit battery life with the same tweaks. Then it comes down to the voltage and clock speeds. CM6 should last plenty long too.
Pretty much identical battery life. I use my phone quite heavily so never get more then about 16-18hours. Maybe in long haul there is a difference but not with a well used device.

this. although i haven't updated yet to the latest CM6. my phone once lasts from 2.5-3 days, with minimal mp3 listening and harcore wifi usage.
before the upgrade to cronos 1.6.1 (best froyo to customize) i was using telusV5...
eclair could last even 50 hours without recharge.
froyo is 25 hours at its best.
i use H data always on, gps on, latitude, whatsapp, wireless almost never, i make lots of calls, i read news, play games like angry birds or asphalt5 few minutes.
i tried every combo of mhz and vsel from 1100 74, to 700 46...no significant difference, battery lasts always 24-26 hours.
I use c.m. roms,from about the 10th of november or something,c.m. roms last about twice as much as my stock eclair did,i'm sorry to say that,but if nadlabak didnt exist,cronos wouldnt exist,feeyo is waiting each time for nadlabak to solve each problem and then he will release his own rom.
Whenever nadlabak doesnt publish his work,cronos is stuck...
Nice guy maybe feeyo,but not milestone expert...
I prefer the original thing,wich is more superior in my opinion...

Right but are you comparing it against a tweaked Froyo?
I used STOCK Telus 2.1 back in the day with the Overclock mod at 1000mhz/60vsel.
I used to push email from 8am to 6pm everyday at work. I had terrible reception at work so I would use 2G a lot during the day, but I would always have 30% AT LEAST by bedtime. I go to work at 8:30am and sleep around 12am.
Now I work at a different place, but I got into work at 11am today and left at 6pm. I took a break in the middle to get lunch, but since I work underground, I turn on airplane mode the whole time. It's now midnight (13 hrs since unplugging) and I'm at 40%. I'd say that if I had 50% of my time on airplane mode that's pretty bad. Other than that the other 6 hrs that I was out int he open I got decent reception. I just pushed gmail, sycned Facebook/Twitter hourly and weather every 3 hrs. Not too bad in terms of heavy use. Also I have the 2G toggle on. I just don't see how I'm draining battery this fast.
So in my case Eclair completely dominates. With HONO or TelusLite mod I probably got a little better battery life throughout the day. I dunno. I only had 1 month of work or so during the summer of using those ROMs before I quit and I stopped pushing exchange mail all day long.
You forget something battery gets worse over time. I had very good batery life on Eclair. Now i use Froyo for quite some while at begining veery bad battery life. Now latest releases quite better, but still not there so i went to try Eclair again for a bit and i found out even eclair doesnt have the battery life for me it used to have, battery is just old and its only half a year since i bought. But take this i charge it everydays ometimes more so in half a year a charged it around 200 times. 300times is the number i think battery gets quite worse.
Maybe one of you battery hawks can help me figure out what the major problem I'm having is.
I see people saying they get 24+ hours on a single charge, yet I have a difficult time maintaining 12 hours with minimal usage.
My provider (Bell Canada) does not have a 2G network I can fall back on, so that's one thing that could be causing major drain.
I am using SuperPower (but haven't noticed any major difference there), SetCPU to set processor to 250 when screen is on, 15sec before screen off, wifi off, GPS off, background data off when screen is off, auto-sync off, and data scheduled to be on for 5 minutes every hour.
I use my phone when I commute to check emails, play Angry Birds, and the like, and generally overclock to 700 or 800 Mhz, with 48 or 50 vsel depending.
Using my phone to play a game, check email, or surf the web for 10 minutes can cause it to drop 10-20%, and even when it's totally turned off overnight, if it's not plugged in it can drop to 20% or lower from a full charge just sitting on my end table.
Any suggestions/ideas?
EDIT: I wanted to add that I tend to use the most up to date CM mod, but have been trying Cronos since the battery life was touted so highly. Unfortunately, I find that Cronos drains the battery slightly faster than the 11.25 mod did. Testing the 11.29 version of CM6 currently.
Ok guys\gals, I have a question that I haven’t seem to find. Right now I’m using CM7 stable on my Nook emmc drive and it works great (Special thanks to all Devs in the Android world that make all is possible). Me and the family are going on vacation at the end of next month and I’m little concerned about battery life on a 5 hour plane ride with my Nook. I know of the sleep bug that CM has and everyone has been working on it but right now I get about day use out of it with normal to heavy use. This is fine because I’m always somewhere I can plug into if the power starts to get low, but now have a little concern since won’t have power. I have successfully converted a few movies using Handbrake and would love to use my nook as entertainment\movies for me and the family while in the Air. So in my testing I haven’t been able to get through a few 2 hours or so movies without the power draining down fast.
Ok with all that being said, it’s my understanding is that the stock ROM with root (Nooter 3.0) works great with Video and has good battery life. Would it be idea for me to just restore to a stock rooted Rom, then create a CM7 SD-Card? The cm7 card would be for my use only till we great back from Seattle. Mainly I’m just trying to keep the kiddos happy since they have never been on a plane before LOL. They LOVE all what my little Nook can do and love watching movies on the bigger 7 in screen (Transformers is Awesome on the Nook by the way). Any suggestions would be great.
Thanks Guys\Gals…
Derek.
Yes, what you propose will work.
I actually have a dualboot on my NC with CM7 as a primary boot; and the stock (rooted) on the secondary partition. (you can follow the dualboot thread in the developer section).
However, while you are actually USING the NC, the battery life shouldn't be terribly different between CM7 and stock. The biggest difference in battery life is while in "suspend" mode, because CM7 doesn't go into as deep of a sleep mode as when in suspend while in stock; so if you are willing to actually power down the NC, rather than suspend, you shouldn't experience any additional power drain while on CM7.
If you still have significantly more power drain on CM7, it is probably because you are overclocking. I have found that shutting wifi off when not being used, being conservative in the screen brightness, and adjust the the processor tweak in the cyanogen settings to "conservative" will help with battery.
All of that being said, I hope to get an external USB battery the next time I need to fly ....
My Nook, running CM7 Stable with screen brightness at 100% and wifi off, uses about 18% of its battery life for every one hour of full-screen video that I watch (.avi files, Rockplayer, mostly). The times that I've flown with it (only once since installing CM7) I usually watch an hour or two of video with internal battery then plug in one of those Duracell rechargeable batteries that you use with a USB cable to power portable devices. Using the rechargeable with a Nook-specific cable (in case that helps) my battery drain per hour of video drops to 10%. On night flights both rates improve somewhat due to much lower brightness levels. Plus, if the Nook is plugged in but inactive (powered on or off) it'll ADD charge 5-10% per hour. One charged 750MAH battery (half the size of a deck of cards) and I'm good for at least 8 hours of heavy use (could go longer, that's the most I've needed).
As jasoraso mentioned, you're really not going to get much better life while using it, if you switch to Stock. Cm7's battery usage is only when usage is suspended as it can't go as deep into sleep as the stock os can.
So even if you move back to stock, you're not going to get better life while watching videos. Your best option would be as both posters before me mentioned, an external charger.
I have only used the note for like 1 day, I really like the screen when I have 100% brightness when I set it to auto it looks so dead and boring..
Have some do more testing, I wonder if it worth to put the brightness on auto, I Do not need to have my phone running for two days on battery so I am willing to sacrifice battery time in favor for greater brightness, however, I still want to be able to go through one full workday, and I will probably watch a lot of videos/tv during the day.

Recommended to turn on Auto brightness for your case since you are probably watch a lot of videos during daytime and yet to survive on one full workday. I am using the custom rom and yet the battery drain so fast (brightness set to 0) as i am dramaholic too. 20-30% drop for 45 minute video.
I generally knows how to flash stuff, use xposed, and whatnot. But I've never really done anything unified to focus on extreme battery saving. I am hoping to be able to switch profiles or something like that so I can keep the phone running on the lowest power possible but still be available for me to wake up to higher power for camera, gps, and messaging uses. The reason for this use case is because I will be hiking half of the Appalachian Trail this summer from Harper Ferry, WVA to Springer Mountain, GA, a total of roughly 1023 miles. Being able to stretch my battery as much as possible without actually enabling airplane mode or turning it off would be extremely helpful. I'm deaf so I cannot just simply borrow anybody else phone to call family. So I must be able to use my current phone for many different functions, including communication.
I do want to be able to use my phone as a primarily social media and messaging device. I have a wordpress blog that I'm trying to get in the habit of updating more often. I also have Instagram, Facebook, and the like. I will be bringing a pocket camera with me but I still want to be able to use my phone to snap pics for easy sharing to Instagram (it will autopost to both Facebook and Wordpress). One of my concern about the camera app is because I know that some ROMs have had issues with the camera's performance after a little while. Being on the trail for about 2 and half month, I won't have any opportunity to fix up my phone. Hence why I want to start testing thing out right now and have about a month or two to go before the actual hike.
GPS is obviously going to be vital. I have a guidebook with me that should covers everything and I almost never ever lose my cardinal direction so I'm not too worried about getting lost. But some GPS access could help just in case I need to figure out exactly how far I've missed a turn or how much I have left to go for the day. Plus it would be nice to have in case of emergency.
I do need bluetooth though. I have a Pebble watch that would be useful for me on the trail, I think. And I will be using a folding bluetooth keyboard on the trail too.
I remember once having Cyanogenmod on an old phone of mine with the ability to extremely underclock. It was incredibly laggy but I was able to create a shortcut to the clocking page so I could switch to a higher speed as I needed it. I'm hoping to be able to do the same with my Verizon's Nexus 6.
Anyway, I'm hoping for any input on which ROM, kernel, etc... would be recommended for setting up the absolute best battery saving and be able to switch the functionality high or low as I needs it. Thanks for any input.

I know that this doesn't exactly answer the question you asked. And I've only owned my N6 since September, and despite flashing everything under the sun with my older devices, I have yet to leave stock on the 6.
That said, are you considering auxiliary batteries (some will give you about 3-4 full charges and are the size of a deck of cards) and possibly solar arrays to top them off? I would consider hanging one from the top of my pack during the day and taking my rests near clearings for direct sunlight. And if you're really looking to stretch your battery, but don't want to run in flight mode, I would consider leaving the BT devices home and maintaining a 2g connection while hiking, only switching to higher power radios when you need to upload images. Remember, in fringe areas, the higher power radios are going to use exponentially more power than when they have a solid signal. And the 2g radio has better reception in fringe areas, besides. Personally, I would use flight mode while sleeping.
One other thing about the radio: this may sound like snake oil, but it is my understanding that the radio's reception can be stronger when closer to the ground based on how the radio waves travel. (It may have been a placebo, but I'm certain I have seen benefit from this on occasion).
I would also make sure that things like NFC, ambient display, screen rotation, adaptive brightness, sync, notifications and vibration are turned off (Being deaf, I suppose that no vibration may not be possible). I would also uninstall (or disable) any and all apps that are not absolutely necessary for the trip. I would also uninstall the Facebook app, if you are using it. If you prefer an app experience for it, I would recommend the Metal app in it's place. No matter what rom you install, you should go for optimizing the power usage.
As for the camera, I would stay away from the AHDR modes and stick to single frame (huge battery saving there!)
I would set a completely black lock screen and home screen wallpaper, too.
I would also suggest an automation app for managing your power usage. Most allow you to have predefined groups of settings that you can assign home screen shortcuts or a quick settings tile. I recommend Automate by Llama Labs.
Good luck! And I hope you have a fantastic trip!
So far that I know of, is that the CPU and GPU speed and governors affect how much the battery is used (#2 heavy power consumer behind the active-matrix organic LED screen with light background) - the faster they run, the more power they require to do certain tasks. I have since set my Nexus 6 phone's processor at 200 - 300 MHz to 1 GHz across entire quad cores (with AutoSMP hotplug and ondemand governors) and GPU locked to 300 MHz maximum, and that configuration have been saving me a lot of power (and quite noticeable with the new battery I installed last week). The ROM I am using is crDroid (Android 7.1.1 Nougat), if you're wondering.
As for GPS, it depends. It may just sip or hog the power. Vibration? It depends on vibration strength (which can be adjusted with Kernel Adiutor Mod app), the stronger it is, the more current it require. Long story short, experimentation is necessary. I also recommend to use black theme under Substratum, it will also ease current consumption by the screen, which I have been doing also (Swift Black Substratum theme pack is what I'm using, perfect amount of blackness to save a good amount of power, and can be found in Google Play Store).
I second cameraddict's suggestion of a power pack. I have the 3000mah version of this, and it works very well.
https://www.amazon.com/PowerCore-Po...&qid=1490282378&sr=8-4&keywords=anker+battery
There are others with higher capacity, but this one would more than double your N6's capacity, and it's the size of a small cigar.

Thanks for all of the ideas. I already have a 10,000mah external battery that I will be using..Unfortunately solar panel are not very feasible on the trail, there is a reason why it is sometimes called a green tunnel.
I'll be removing virtually everything unneccesary from the phone. I do use Facebook a lot but I'm planning on using titanium backup to freeze the app (plus other apps) when I'm not using it so it should not be a problem there.
Good idea about limiting to 3g when I'm on the trail. There, I only need minimal data for emergency messaging and basic GPS sharing.
I do have a pebble smartwatch and I'm thinking that maybe using it would offload the battery usage from the phone to my watch allowing me to still have some notification and other details on the watchface.

Yeah, that's why I'm asking about it at this point. I feels that 2 months are long enough for me to experiment with this. I'm hoping to do the trick with governers so I'll be reviewing your comment after work today.

I'd go back to Marshamallow and not Nougat for battery savings. Also "Pixel Off" app to reduce brightness and turns off 1/2 pixels to save battery. You can also use Black and White mode in Developer Option to save battery. Kernel Audiutor can underclock to 1190 Mhz top and 300 Mhz bottom with "conservative" governor and "powersaving" mode.

I disagree, because I haven't seen a difference between Marshmallow and Nougat regarding battery saving (even though stock Nougat ROM blows - all the reason to install custom LineageOS derivative ROM instead) - I know because I checked with new battery installed and I am still at 56% battery remaining ever since 5 days after charging to 100%, on the Nougat ROM with aggressive economy CPU settings I tailored on my phone, however, as for 1/2 "Pixel off" and black - white video option to save a bit juice, I agree even though it will make the UI quite ugly.

I had another thought this morning. ( I realize that all my suggestions are minor, but lots of minor adds up.) I would also turn off all animations in Developer options.
I also wanted to agree about the monochrome color option in Developer options. And the dark theme, in general.
As for kernel settings, on other devices I've had, I had quite a bit of success with UV. If memory serves, once I had finished a weeks worth of experimenting, I gained about 10% from UV. And using the ondemand governor, with lots of tweaking, I was able to increase battery life without too big of a hit on usability. I found that powersave always created a very unpleasant experience.
edit:
One more thing, from my experimenting, you can also gain several % by changing how you interact with the device. Your governor will spike the CPU every time you touch the screen. One major difference you can make today is changing that behavior. When reading, scroll from the bottom all the way to the top of the screen and don't touch it again until you need to scroll all the way from the bottom. This isn't as hard or as silly as it sounds. Watch how you use your device, Many people touch the screen a lot
Despite every effort and tweak you can think of, you'll achieve only minimal battery life extension. Your best bet is to use the few tweaks that you feel are acceptable and rely on your 10000mah battery - nothing else will have anything like that effect.

Respectfully, I disagree. Each .5%-2% gain adds up. 10 tweaks at an average of .75% gain is 7.5% Add one major tweak that gives an average of 8% and you now have a 15.5% gain. My battery, right now, on official 7.0 (with no tweaks) averages 40 hours on battery with 6-8 hours of SOT. I have many other metrics for this... So 40 hours x 15.5% = total battery life of 46+ hours. Those 6 hours are not minimal effect. Especially when there is no outlet nearby for days.
It is possible with the right mix of OS tweaks, app settings and kernel tweaks to see an average gain in the 30-50% neighborhood.
This, by the way, comes from years of tweaking and experimenting on many devices. Going back to 2003 or so. You can check out my old posts on optimizing my old Galaxy S2, I shared a lot about that device.
No need for "respectfully" I'm sure it's really just a preference. A lot of tweaks may well add up to a respectable extension, but they will never triple it as a 10000mah battery will. I'd rather carry the extra few ounces and be sure that I have a reserve. Not arguing, just stating my preference.

Gotchya. I just mention all the tweaks AND the battery for his use case. As an initial full charge plus three extra charges(with the 10,000mah) without tweaks (conservatively) would net him a total of about 8 days of use. But with 20% savings from tweaks, that goes up to nearly 10 days. Quite a useful increase.
ps... I wrote: "respectfully" 'cause you know how forums can be. Sometimes I think it's best to be proactive and let the person your responding to know that you're not arguing. Cheers!
Morning all.
Something that has been slightly bothering me since I got this phone....it has a massive battery, it can be heavily customised with roms, xposed modules, magisk modules and all manner of tweaks. Probably one of the most open and dev-friendly devices I've ever had.
Yet, no matter what I do the only way I have ever been able to get more than 2 days out of a battery is to literally not use the phone.
I have had devices in the past such as Xperia Z3 Compact, S7 Active and others with smaller battery that were easily able to push 3 days with regular use. Hell, the Z3C was able to get up to 5 days with a little bit of trickery turning off radios when not in use etc.
Is the extra diagonal inch of screen realestate really enough to destroy the battery longevity? Typically with normal usage I am seeing 2 days with about 4.5 hours of screen-on time.
I've experimented with just about everything to push this out including no official facebook apps, decreased resolution, medium power-saving mode, kernel tweaks (currently using TGP rom and kernel), auto-sync turned off. Going beyond this I feel like you may as well just use a push-button device.
Any devs care to comment? What is the main factor that eats the battery on the Note 9? Is the exynos processor just not that power-efficient? Am I missing some hidden gem?
I guess the next step would be to transition to an AOSP based rom where the customisation is not constrained by baked-in samsung features but again, this is giving up a lot including proper s-pen functionality.
I recently kitted out an LG V30+ for my wife and it is just insane to me that a phone which only has a 3300mah battery can get the same life as the Note9 or better.
Is there some strategy I have missed or is this really the best we can hope for? Seems like an extremely inefficient use of 4000mah to me.

Morning all.
Something that has been slightly bothering me since I got this phone....it has a massive battery, it can be heavily customised with roms, xposed modules, magisk modules and all manner of tweaks. Probably one of the most open and dev-friendly devices I've ever had.
Yet, no matter what I do the only way I have ever been able to get more than 2 days out of a battery is to literally not use the phone.
I have had devices in the past such as Xperia Z3 Compact, S7 Active and others with smaller battery that were easily able to push 3 days with regular use. Hell, the Z3C was able to get up to 5 days with a little bit of trickery turning off radios when not in use etc.
Is the extra diagonal inch of screen realestate really enough to destroy the battery longevity? Typically with normal usage I am seeing 2 days with about 4.5 hours of screen-on time.

This is what you get when you use a high performance chip.
If it was like cars.. just because the gas tank is big (battery) doesn't mean that the engine won't consume the fuel faster than a more Efficient engine (cpu) with less power.
Other phones might be able to last 3 days, but they also dont have the performance capabilities. Turn on extreme power saving and see how long the phone lasts ...
I'm using stock unbranded ROM. I also adp uninstalled all the Facebook system apps (devil-ware). With Pie + OneUI + Night mode + Dark UI apps, it's the first time I love stock. I bet your non-stock ROM + TGP is the culprit.
I charge nightly on a wireless charge pad; easy on the battery. In Device Care, I run the default "Optimized" setting. I use it moderately for the first 12 hours of my working day (meetings phone calls), and I often have 85-90% charge left at that point. I then use the phone HEAVILY for the next 4 hours (watching video, reading, etc.), and at that point I am never below 50% (often 60-70) when I put it back on the charge pad, go to sleep, and start the whole thing over again. I have the US version (Snapdragon), darkmode and auto brightness is always on, and I use Automate to toggle my wifi off when not home and back on when home. Other than that, I have gps, bluetooth, and phone data always on. Bluetooth pairs with my watch and car, and gps auto-toggles by the kernel whenever I load maps or whenever my Life360 app updates my location (every few minutes).
That's all fairly normal use with a bit of power-savings thought into it. If you cannot get similar performance without your screen brightness jacked way up and wifi always on (that eats battery as you move around), then maybe you have a power-hungry app. Check your Device Care section of Settings, and start watching your "Usage by apps".
Also, it's better to slow-charge than fast-charge (wears it out more quickly). And you are better off charging nightly than waiting two days until it's very low.

A lot of people don't realize the huge difference that your cellular connection strength makes a difference on your battery.
Try working in a all brick/stone bank building, where 250kb/s is a good 4g download speed... Then see what your battery looks like after a few hours.

YEP!
And same goes for wifi.....
wifi and cell radios can really eat up battery if they are trying to maintain a connection in areas where wifi/phone signal is weak. And app like Tasker or Automate can toggle these on and off, depending on your location, and really save battery.
Well, that probably explains a few things. I moved in to a SOLID brick building recently with double glazing everywhere and multiple solid brick internal walls. First time I've ever battled for cell and wifi signal...that does explain a lot. I guess 2 days is still pretty good. Might end up with one of those 10,000mah Chinafones eventually ;p
