I've got my autonootered 1.1.0 NC and it is working great. The only thing is the battery seems to be running out really fast on this. On my wife's autonootered 1.0.1, the battery isn't running out nearly so slow and we have all the same apps, although some of mine, since it's newer, may be more recent versions.
One thing I noticed is that she has very little time on "Android system", whereas 2/3 of the drain on mine is from that. The only apps that typically run though are advanced task killer and batter indicator. I regularly shut down everything else.
I've also renamed phone.apk and the telephony(something).apk on both of them as well.
Is there anything that will deep dive into "android system" on battery use? There are no rogue apps running (at least according the task killer). Or any suggestions?
First thing I'd suspect are live wallpapers followed by widgets. Verify that you have a plain wallpaper and remove any widgets that you would anticipate are doing frequent polling of any kind. I'd remove that battery indicator one and see if that helps.

Running zeam with plain nook wallpaper (just like on my wife's nook). No widgets. Am seriously wondering about the battery use thing though.

Like I suggested, uninstall that battery indicator app. You didnt mention which one it is so for now based on the only info youve provided thats the only advice I can give.
In one test I did on my nookie froyo install I'm running, I tried a new spruced up kernel and ran a battery status widget. The widget caused the nook to stay out of deep sleep and also out of lower clock speeds when idle resulting in horrible battery life.
Are you running setcpu on either or both nooks and if so are they set the same?

Try systempanel lite task manager by nextapp in market. It might help show ram and cpu usage of things.

When not using wifi turn it off. That will save you some battery life as well.
Keep the suggestions coming
The battery app is "battery indicator". It is usually running on both nooks, but mine has a more recent version I think (this is my main suspect right now).
We always kill the wifi when not using it, so I know that's not it. Also not running setcpu on either.
I sucked down probably 5-10% while just reading with only "advanced task killer", "battery indicator", and the stock reader running for less than an hour last night.
I'm going to try systempanellite and see if that tells me anything. Also going to charge it up to 100%, boot into CMR and reset the battery stats.
If it is the battery app, wondering how to find the older version to downgrade to, or maybe just find a different one, I suppose...
45 minutes of simply reading and went from 99% all the way down to 88%. No battery utility. Systempanellite (only running for a few of those minutes) didn't really show anything sucking either.
Only other difference I can think of now is that I disabled OTA updates on my wife's nook.
I wonder if I just got a bad nook, battery wise...

So ~10% from about ~1 hour of use? Might be a little high for just reading, especially if your brightness is low and your wifi is off. However, I note a 10% per hour discharge with average use. I get about ~2% or so overnight loss with screen off and wifi off.
Rooted 1.1, Monster root pack. Overclocked with Dalingrin's kernel.
Looking at the two nooks, side by side, I notice that on mine, AFfileDownloadService and CloudService are background, while on my wife's, they are 'Service'. When DeviceManagerService is running, that is also background on mine and service on hers.
Could that be why the "Android system" is sucking so much battery? SystemPanel doesn't show anything sucking cpu....
I know it's supposed to be around 10 hours, but that works out to be about 7 hours reading a small, simple epub, which has me concerned.
I did lower the brightness on mine to match my wife's exactly. It was less than halfway, but heres was lower, right in between the two esses at the end of 'brightness'.
A more deliberate test shows 1% drain every 5 minutes (almost exactly) while just reading. That's a little over 8 hours and still less than I expect. Maybe I need to tweak the brightness a little more...
Hey,
I own 3 tablets and considerig the NC for the wife as #4
however I was wondering if anyone has done some specific battery tests for example:
1) How long from full to empty when reading a book?
2) On stand by
3) Off (you know you charge it on monday and dont go to use it until friday)
4) media play? (mp3, avi's etc)
5) light wifi internet use?
she will use it MOSTLY as an ereader however i will need to use an alt FW so she can load some of her nursing aapps (epocrates etc) but she HATES the 3 hour battery on her augen
For me, using strictly as a reader, it will last between 8 and 10 hours, depending largely on the screen brightness. For example, I have my screen brightness down to maybe 17-18% (roughly judging slider). I get around 8 hours there, but by setting the 'night mode', it bumps it up. As always, YMMV...
cool thanks
anyone else?

In my experience the biggest battery drain is WiFi so I leave it off most of the time. I usually leave the brightness at 25%. I also don't let the battery completely drain -- 10% is about as low as I go. So with those things in mind...
1. Reading: 9-10 hours
2. Stand-by: drops a few % each day
3. Off: I never turn it off completely but I would expect minimal battery loss
4. Media: I only play hardware decodeable media (MP4) and get 7-8 hours
5. Browsing: Not much experience but I would guess 6-7 hours
If you keep the stock rom, it would last longer. I have two. One is running cm7; and one is stock. The stock lasts way way longer.

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'm running pure stock rom, no rooting, no updating, V10E just bought it less than a week ago.

Now I tried the following two things with my phone:
For the first night, I left it at 2G only, with autosync disabled, and wifi,bluetooth,gps etc. off. All above apps were running, viber and whatsapp included, and obviously with no autosync, Gmail was not, so only the Email app that comes with android was running and checking email. In one night, it drained no more than 6%, over 8 hours.
The second night; again 2G only, and everything off, except for autosync, which I set to sync gmail only, and disabled the native Email app. In 6 hours overnight, battery drained 10%. This does not make sense for me, why would gmail drain so much battery?
Next, while I can live with those stand-by times, what is wierd is that while using the phone, the battery drains at unbelievable rates. I leave it mostly on 2G, barely using 3G every now and again. This morning, I left the house with 90% battery. charged it on my way to uni with the car, then when I got there played some games and a few songs for maybe 15 mins, then my friend came and we goofed around taking a video with the effects for a few minutes not more than 5. THen I went on for my lesson, took about 15 photos with no flash, with CamScanner and organized them into documents, then used regularly my phone to send texts, whatsapp and viber, then browsed the web for maybe 10 mins on 3G. By 12 o' clock, my phone was nearly dead (10%)! This does not seem normal to me, even though the standby times range from excellent, to acceptable it seems like the phone uses an enormous amount of battery when in use generally.The brightness varied from about 10% indoors, to 80% when outdoors. (most use was indoors). To make the time clear, I got to uni at 6.30 am, and while using the phone and games the phone was still connected to the car charger.
I have not done any modification to the phone. NO updates, no root (which I heard causes battery drain) no nothing.
HELP ?

hey, some tips if you want to extend your battery life, that worked for me, set display bright 50% and check auto bright mark, use some app like antutu cpu master (root required) to down your cpu clock to 1200 Mhz or 1000 (i used 1000Mhz), and also you should consider upgrade your firmware to v10h, you can notice the change in the battery duration, for me with all this tips, my battery drains about 30% from 5am to 3pm with a normal usage (gmail sync, whatsapp, email sync, facebook, twitter, some calls, sms), if you play casual games, battery duration goes down, but with cpu speed set to 1000mhz you can obtain a little more while gaming and avoid overheating

Thank you Ok, so is it safe to change to v10H? Will I need to factory reset everything? Because I would really like to avoid that? Plus to downclock would I need root? THen I'm going to definitely need to factory reset right?
Also which rom should I go for? I keep seeing the "Stock" roms and the deodexed zipaligned roms, which are better? If possible can you include for me a link to the actual rom you are using? thanks
BTW:: I don't have auto brightness setting!!
And is it wierd that gmail seems to be using way too much battery on standby?
This is actually quite 'normal' as most O4X users experience this notorious battery drain.
To extend your battery, you might want to do these:
1. Root your phone and uninstall any unnecessary bloatwares
2. Install battery saving app. A word of precaution though, for some it works wonder, and some experience disaster. I personally use Juice Defender and have seen some battery improvement.
3. Root your device and edit your com.telephone database. I've seen major battery improvement by doing this.
4. Get yourself some power banks. This thing comes handy when you're running out of juice.
You can browse this forum to do all the above.

Explain the com.telephone procedure? I'm seeing some improvement by using apex and freezing bloat, lower brightness etc but could do with a little more juice

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.

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
