[Nook HD] Battery life and CPU underclocking

Hi All,

First of all, thanks for such a wonderful ROM. It works amazing and with the amount of customization available, who needs a Nexus...

I had 2 questions about Carbon ROM (or even CM 10.1)

1. What is the battery life that I can expect from Nook HD running Carbon. This is the only thing that is really disappointing me. Coming from iPad the battery life looks dismal. I think I can get 4-5 hours or light web browsing max. And when the tablet is sleeping, I have 0.5% drop/hr.

2. I tried underclocking the CPU to 1100MHZ using the built-in performance tool, Antutu CPU and some other tools. I can underclock the Max freq temporarily but eventually, the setting is reverted to 1500MHz. Why does this not stick?

Running B8 on an HD+ and I'm loving it, with only a couple small issues.

Memory management seems a little wonky. I've checked the recent tab and frequently see it as showing under 20megs free. Ended up using AKMO to keep it from locking up, but it still seems to be pretty memory intensive.

Still getting the occasional soft reset to boot animation. It only seems to occur when I'm using the browser, and seems especially prone when another app opens the browser. FWIW, I run Dolphin beta with Flash installed.

Other than that, you are a minor god of wonder KS. Thank you for a great rom.

Thanks, will check it whenI get back home...

Because you're fighting the kernel, system settings. You could try something like virtuous oc daemon with oc/uv beater... But just leaving it on sakuractive, at default settings should net you at least 7hrs of screen on time.

Have you disabled halo? Try betterbatterystats and let it tell you what is using the most battery...

Carbon settings for additional users

First, I want to say thanks for what appears to be a great ROM. I just rooted and flashed CM10.1 on my nook HD+ yesterday. I quickly switched to carbon since I saw you have LCD density options which my old eyes need. I have flashed MANY custom ROMs on other devices but I have never setup additional users. I created an account for my wife and i wanted to configure a theme for her. I have no problem on my account (owner and I have root). The screenshot attached shows what I get when logged into her account. Can I fix that and how?:confused:
[Nook HD, HD+ Android Development] killersloth:
Some things are a little strange, but runs great so far.

Update center = fc maybe because I excluded goomanager

Dark toggle = momentary 180° rotation

Don't even bother using lock screen security, i broke lockscreen gesture password.

Work in an hour, ovation is still building

Probably will update carbon tonight too

I've never used multiple user option, I can't help with that :(

I had a multi user problem... she made me go buy another nook :p
[Nook HD, HD+ Android Development] sameer_g:
Got it make sense that kernel is trying to set it to 1.5GHz... I think I will leave it as it is...

As far as I can see, in B8 Halo is disabled by default. Atleast under, Settings >> Carbon >> .... >> Enable Halo is unchecked..

I am quite new to android ecosystem.. Is there something I am doing wrong?

Thanks..
[Nook HD, HD+ Android Development] blast0id:
Can you explain a little further your issue ? Not sure I understand just by looking at the screen cap...
[Nook HD, HD+ Android Development] henry8668:
got black strip on the top and bottom frequently, usually reboot fixes it but it comes back... I am using B7. anyone has same experience? how to fix this?
[Nook HD, HD+ Android Development] Reatret:
Yeah I get this with b8 also
[Nook HD, HD+ Android Development] RichMD:
Thanks for the reply. In my post I mentioned I was trying to set a theme for her account. If you go into settings, you will see a carbon section with Carbon, Dark carbon, Performance, and Themes settings. The screenshot shows Carbon followed immediately by the Device Section. This attached should make it more obvious. The first pic is what I see when logged in with my ID. The second is when I am logged in with her ID.
[Nook HD, HD+ Android Development] blast0id:
I'd like to know also!

Edit: also on b8

---------- Post added at 08:30 PM ---------- Previous post was at 08:24 PM ----------

I don't think it's possible to set per /user settings for themes, but you can use a launcher like APEX /nova /or trebuchet that has theme capability and set individual user theme settings for the launcher... That's what I've done with apex...
[Nook HD, HD+ Android Development] dmullens:
Only way I got it fixed was by setting DPI to 240. Started happening on B7 when I went 320 for DPI.
[Nook HD, HD+ Android Development] killersloth:
Running builds for carbon now.

Root box is uploaded, new thread, there's some bugs with rotation and screenshot is saved upside down on hummingbird, sideways on ovation. Very much usable, but very also a banged together first release lol. Enjoy :)
[Nook HD, HD+ Android Development] anqi2000:
Hi, Killersloth. I recently installed CarbonRom but have one problem. Tried to search this thread but didn't find any answer. Maybe you can help me out here. My screen blacks out whenever rotating for a second or two. It doesn't always happens but did happen for about 70%-80% percent of time. Any solution or it's just a problem of my device.
[Nook HD, HD+ Android Development] LucaToo:
Have had the same problem with the last couple of builds. Maybe not 70-80% of the time - but enough that it is noticable.
[Nook HD, HD+ Android Development] killersloth:
It does definitely happen sometimes. Even got a reboot trying to rotate once on HD+, I'm not sure what is the cause.
[Nook HD, HD+ Android Development] anqi2000:
It may be just a small bug for someone else but I found it to be pretty annoying. That's why I am switching to cm10.1 for now...

---------- Post added at 09:54 AM ---------- Previous post was at 09:49 AM ----------

Does it happen a lot on your device or only occasionally?
[Nook HD, HD+ Android Development] CubeCloudOS:
Random reboot with Nook HD cover while plugged in

Press power button while screen off it reboots

Other than that great!

Usb OTG host works fine

Awesome, thanks for putting so much work into this killersloth

Thanks you are an awesome Dev!
[Nook HD, HD+ Android Development] Lavrentsii:
On HALO, swipe-distance between notifications is...a bit much, on Landscape orientation. Is there a way to change this in an option, or something that has to be fixed upstream?
[Nook HD, HD+ Android Development] jpisini:
Dang I just installed 8. What are the changes? 8 is working really well thanks.
[Nook HD, HD+ Android Development] jpisini:
Installed 9 so far so good. Host mode works so does HDMI out. Only issue so far in landscape (hole upper left) top edge is not very sensitive but honestly if that is the worst I find then I will be thoroughly impressed.
[Nook HD, HD+ Android Development] killersloth:
That is very long swipes lol

[MENTION=3459071]killersloth[/MENTION],

If we installed b8 clean, do you think a dirty flash is ok or at least restore missing USER apps and data via TB?
[Nook HD, HD+ Android Development] 123421342:
Dirty flash is usually okay if it's the same ROM because it wipes system
[Nook HD, HD+ Android Development] killersloth:
Should be just fine :)
[Nook HD, HD+ Android Development] Lavrentsii:
On B9, I get a lot of force restarts when using chrome. Reverted to b8

EDIT: on ovation
[Nook HD, HD+ Android Development] bckrupps:
not sure if you included verygreens screen zip in this but my touches work fabulous in this build. don't change it in future builds please lol
[Nook HD, HD+ Android Development] jpisini:
Try Dolphin been using it well over an hour no issues
[Nook HD, HD+ Android Development] Lavrentsii:
Does it have an addon that allows it to sync at least bookmarks with Chrome?
[Nook HD, HD+ Android Development] jpisini:
Never tried to be honest.
[Nook HD, HD+ Android Development] dmullens:
Is this an issue? I was going to update, but I use chrome a lot. Anyone getting chrome to work on HD+?
[Nook HD, HD+ Android Development] _dave:
I did not have any problems with Chrome. Opened, closed 12x. Even grab a file. Working fine for me.
[Nook HD, HD+ Android Development] bckrupps:
I only use 1 home screen. anybody have this carbon wallpaper or know how I can set it up to look proper on my home screen and yes I tried Google but no luck lol can't upload. its the 1st one in the second screen screenshot of this thread. grey and says carbon. looks like an envelope.
[Nook HD, HD+ Android Development] Colt77:
Settings - Display - Wallpaper - Carbon Wallpapers.
[Nook HD, HD+ Android Development] Lavrentsii:
Jumped the gun on this one. Ooops.

I had changed some RAM-related settings in performance control and forgot about it. That's what was causing the issues. It just always seemed to happen while using Chrome.

So, disregard that other post.

EDIT: Running B9 again - without the problematic settings - and all is well.
[Nook HD, HD+ Android Development] bckrupps:
thanks I got that. I only use one homepage and it displays wrong. down and to the right. just thought someone might have a copy with the proper resolution for a single screen. thanks anyway
[Nook HD, HD+ Android Development] bckrupps:
my WiFi doesn't seem to shut down when it sleeps. It is turned off in settings I believe. is this a known issue with this ROM? I have it set to never.
[Nook HD, HD+ Android Development] blast0id:
think about that for a second...

think about it...

still thinking? I would hope so...

get it? never... as in it won't turn off... EVER, unless you do so manually...
[Nook HD, HD+ Android Development] bckrupps:
the option says "keep WiFi on during sleep"

I selected "never"

DRINK another one!
[Nook HD, HD+ Android Development] sameer_g:
Can anyone let me know what is expected battery life using this ROM (B8) on a Nook HD with default settings. I generally keep screen brightness to minimum and I think I can get 5 hours max of screen on / internet surfing time (Chrome). I am not sure how I can verify that I did not get a nook hd with bad battery. Also while in deep sleep it is losing around .6%-.7%/hr.

Is there a way to verify battery condition accurately?
[Nook HD, HD+ Android Development] blast0id:
I wish I could say alcohol was the culprit, but I swore the setting said "Turn WiFi off during sleep"... I don't know if it was a different device that it was that way, or my mind is dyslexic with memories... lol... at any rate, my apologies... honestly just now is the first time I've looked at the setting on this device, so I was going on an assumption and an erroneous memory... double fail, and we all know what the say about ass-u-me-ing things... lol

so please accept my sincere apology for making a right public ass of myself =)
[Nook HD, HD+ Android Development] henry8668:
turn off wifi during sleep? for me it reduced battery usage to 1% for 8 hours.
[Nook HD, HD+ Android Development] sameer_g:
Yes I was reading through the forums and saw this. I will try this out today. But this still does not solve 5 hours of screen on time just surfing internet in Chrome with maybe FB and email clients running in background. How to I accurately benchmark my battery performance. Are there any standard tools that I can use.
[Nook HD, HD+ Android Development] webdroidmt:
Nah, no public a$$ing here. :D If I'm not mistaken, I believe that when I had my Touchpad running CM9 it was "turn wifi off during sleep" and I always kept it to "never" due to wifi cutting out.

So, I never paid attention to what it actually says in the advanced wifi setting and thought exactly the same as you. Plus your post was cool, reminded me of Barney on HIMYM saying "Wait.... for it"! :laugh:

[Nook HD, HD+ Android Development] bckrupps:
lol no big deal. I wasn't offended just having fun with you :) personally I think the way its worded is dumb myself. none the less it isn't working for me? does it actually work for anyone else or should I manually turn it off each time :)
[Nook HD, HD+ Android Development] jamus28:
I was getting way more than 5 hours WiFi surfing with b6. Closer to 10% each hour. Use wakelock detector And better battery to see whats using it up.

I'll see what b9 is like.
[Nook HD, HD+ Android Development] killersloth:
My HD+ been sitting idle since b9 release, two days, 94% but basically no screen on time. So there are no native idle drain issues, most likely rogue apps draining for some. Carbon has the feature to kill all apps completely by long pressing the clear all button in recent apps list, using that before long terms of no usage might help keep those draining apps under control :)

Also been using halo on my gnex, causes slight ui lags here too, loading animations, gesture keyboard animation etc.
[Nook HD, HD+ Android Development] Lavrentsii:
Got a minor bug to report:

On my d2att running carbon, the reboot shortcuts in the DPI switcher reboot the phone- as intended.

On the ovation though, it takes me to recovery.

Don't have a hummingbird to test this with though.
[Nook HD, HD+ Android Development] killersloth:
I've noticed this too. I think it has to do with cyanoboot getting confused. Kind of like when it boot loops 8 times or whatever and it triggers reboot into recovery. I haven't looked into it though. My laptop is in rough shape and has been off the last two days. I'll be working extra hours/shifts to try and replace it with a proper build machine. Been scouring newegg pricing parts and such, I prefer to piece it together myself to get the best out of it ;)
[Nook HD, HD+ Android Development] rushless:
I get that with wifi on, using stock 2.1 or CM 10.1. With wifi off, it is 1% in over 14 hours (not had off beyond that to check).

The opposite of that is my Excite 7.7 and TF300. They drain four times that with wifi off and worse with it on.

Terrible power idle power management on most Android devices in general.
[Nook HD, HD+ Android Development] killersloth:
Most devices with cell radios drain ridiculously while off WiFi when in low/bad signal areas. That's why they drain less with WiFi on :)

And, thank you Robert :)

(Just realized the super intuitive gesture keyboard decided I wanted to write a completely different commonly used name from my contacts lol)
[Nook HD, HD+ Android Development] ms2003:
one question, I add this row in the build.prop 'qemu.hw.mainkeys=1', normally it should hide the button menu bar (on my NT cm10.1 it works, I didn't try on HD+ cm10.1), but on this carbon ROM on H+ can't work. is there any ristrictions to use build.prop config on this ROM?
[Nook HD, HD+ Android Development] killersloth:
Just set the menu button to "don't show".

I don't have my nook with me at work but there is an option to hide/show that.
[Nook HD, HD+ Android Development] blast0id:
did you make sure to put it at the very end of the build.prop? otherwise it might be getting overridden by a duplicate line below it... as long as your line is the last one, then it should take...
[Nook HD, HD+ Android Development] CubeCloudOS:
Great battery on Hummingbird B9 what the heck did you do sloth??

After leaving it at 69% overnight I watch Netflix for 1/2 a day and some casual browsing after and its still going strong. :D
[Nook HD, HD+ Android Development] bckrupps:
might be a dumb questions but I have read about it on other devices. are there any files such as language files or devices files within the ROM that can be deleted or country based maybe to free up more permanent system ram for the user.
[Nook HD, HD+ Android Development] killersloth:
I believe free space in system partition has no effect on performance. I could be wrong.

I know on my old htc devices they were pretty much loaded to the brim with HTC bloat and (non)Sense which didn't seem to effect anything on a performance level. RAM(random access memory) isn't space in the system partition though.

Wifi problem, not unique to this rom

Can anyone help me?

I am in a campground with wifi service. I have three different Android devices, an HD+ using this rom, a Note2 nonstock, and a Samsung Galaxy Nexus, also nonstock. All three devices connect to the strong wifi signal, and immediately after getting past the password, disconnect and make some statement about a poor signal. I am currently posting from an older iPad that has no issues whatsoever. What is going on here, and what can I do?

Re: installing apks, if you have Halo enabled, it's most likely the culprit. This was an issue when Halo was first introduced, don't know if this is still the case as I don't use it. I believe it has something to do with a security issue???

If Halo is in fact the issue, disable it and you should be able to install apk files.

Thank you killersloth for the great rom.

Has anyone experienced keyboard rotation not working? I'm on B8, in landscape, and the stock keyboard shows the portrait size (does not stretch to fill the width).

EDIT: Restarted and it's working fine. I guess it might just be a temporary bug! Thanks again!
[Nook HD, HD+ Android Development] JDMpire:
I'm having some problems with charging. I tried a new kernel even, I get the little lightening bolt to appear on the battery icon, but the device status shows "No Charging". The LED next to the dock connector lights up orange. I tried to connect it to my macbook, iPad wall charger & nook charger. All the same results.
[Nook HD, HD+ Android Development] CubeCloudOS:
I know this isn't related but how did you get the iPad charger to work?
[Nook HD, HD+ Android Development] JDMpire:
Sorry I should have mentioned that in order to get the iPad charger to work I used a "Cheater charger". Basically that means shorting out the inner 2 usb wires (4 total, 2 for power 2 for data), the the data wires that you short out. I actually had to make this cable for my PS Vita but a lot of other devices, such as our HD+ need this kind of cable to charge. Why this is I have NO idea, you can get more info here:

I made mine out of a USB extension cable. I believe they sell these online now if you dont want to make one yourself...

Tablet UI and soft reboots

So I love this ROM, but force reboots have been a pia. So I played around with settings based on what little I could figure out from who has and has not complained about the issue. And it looks like tablet ui might be the cause. I've been running now for 8 hours and haven't had a single issue so far. Of course I'm willing to bet that it'll start as soon as I post this. :)
[Nook HD, HD+ Android Development] blast0id:
I haven't had any random reboots, still on b8, but not using tablet ui...about to flash b9...

---------- Post added at 09:56 PM ---------- Previous post was at 09:55 PM ----------

Very useful post, thanks!
[Nook HD, HD+ Android Development] killersloth:
I use tablet ui on my HD+ and can say that there's definitely a problem after long amounts of usage without locking the screen, especially in portrait orientation. RAM gets low and device possibly reboots if it's bad enough. I'll be looking into it. Also wanting to work on fixing everything up from verygreens device trees for strict aliasing though, that's going to take some time and I have been letting the laptop rest for a few days now.
[Nook HD, HD+ Android Development] walpurgisbirn:
Take your time, let the laptop rest. Everyone here appreciates the work you've done already, for all it's little quirks, thus is one of the most functional roms I.ve seen.

As a side note, since I tend to favor performance over battery, I set the sceduler to deadline, and the governor to wheately. I'm finding even some of the more memory intensive games (Dungeon Hunter 4, Need 4 Speed) tend to run smooth and lag-free.
[Nook HD, HD+ Android Development] killersloth:
Yeah wheatley stays ramped up nicely for games like NFS and nova ;)
[Nook HD, HD+ Android Development] jpisini:
I have run b9 for a few days it runs well the only issue I have had is every once in a while it won't log in. I have to reboot then it works fine for a few hours or a day and does it again.

Just want to say thank you. Bought a HD+ for wife and myself. Mine has this ROM and wife's is stock. Kids all prefer mine to the point of actually looking for it when wife's is sitting right next to them and given their lazy nature that's saying something :)
