Nook HD with CM 10.1/Carbon eMMC - battery life - Nook HD, HD+ General

Hi All
I recently got Nook HD and immediately flashed first CM 10.1 for a day or so and now Carbon rom. Overall the tablet works great of web surfing (mainly Chrome) and some other app such as Zinio, Facebook etc... (no games). Though battery life of this thing is pretty dismal. I think I can get maybe 4-5 hrs max of web surfing and reading with screen brightness between 10% - 15% and BT off/WiFi on. Is this the same as everyone else or others having better experience. I also have around 0.5% battery loss when the tablet is sleeping overnight.
And people who have Nook HD+, is the battery life significantly better?

New ROM installs usually need a few charge cycles to settle in. Battery life should improve a bit.
Also everyone's battery isn't the same, sometimes you just get a dud.

Thanks for the reply. How can I make sure the battery is not bad. Since the device is still returnable I want to make sure it is OK. Also since I did not purchase the device from Barnes and nobles it will be a pain to follow up on warranty later on.
Any suggestion would be greatly appreciated.

Just keep track of battery life.
If you're within your return period from wherever you purchased from just initiate an exchange.

Thanks for the suggestions, but OM seems to be completely out of Nook HDs. Maybe I can return the device but no way to exchange it for a new one. Does any one know if I can take it to BN store for a replacement?

Not sure if they'll take back a Nook HD under warranty for battery life claims. You'll have to talk to them and find out.

Battery life stinks...

Hey guys what is up. I'm just wandering.. my Droid is brand new. Got it 2 days ago. Today I had to recharge my battery twice. I did use it a lot... so that may be it.. and when I didn't use it the battery life stayed the same for as long as I didn't touch the phone. Is my battery good? I got the app that tells me the temperature and everything. The hottest was 112F. It says my battery health is "good health". Will my phone hold a charge for a longer period of time after it has been charged then drained... and repeated. Does it just need to be broken in? Thanks for reading this whole essay I wrote you guys.. Haha. Well thank you so much again... and if you can please get back to me as soon as possible that would be great!

You should really search a little bit before you post. There are COUNTLESS threads on battery life.
Your best bet, until HTC fixes it, is to charge until the phone says you're at 100%, then turn it off and charge until the LED turns green. Charging and discharging really won't affect anything - their is no "memory" with their batteries.
Okay, thanks for the quick response. I appreciate it. Sorry. I should've read.. I was just a bit anxious. My apologies.

You could always trying running one of Hydra's Kernels as well. I don't know if anyone has gained better battery life because of doing so... I use his kernels for the features.

stock speed undervolt is the way to go. I found battery improvement. Hydra Kernels are the way to go.

What is that? Do I get it in the app store? My battery is getting pretty warm now.. even when I touch my screen I feel it.

Check Settings > About phone > Battery and make sure up time and awake time aren't the same.
If they are the same, it means something is keeping your phone awake when the screen goes off, which drains battery.
I just got my Droid Incredible a few days ago too, and I knew coming into it that the battery life has issues from a lot of users, but man, it really sucks!
I have it fully charged at 8am, and by 3:30 (with very moderate use), it's already at 20%. I've disabled everything I can (WiFi, Bluetooth, GPS, live wallpaper, installed ATK and keep my tasks at none, etc), and still the same.
I really love the phone (it's amazing other than battery), but the battery life is such a big deal for me that I am really thinking about returning it and waiting for the Samsung Fascinate to come (hopefully sooner than later). Thankfully I have until Aug 30 to call Verizon and return the phone... i sure hope the Fascinate gets a definite release date by then.
I'm going to try the full charge + phone off + charge again to see if that improves things, but other than that, does anyone recommend the Seidio 1750mAh battery or the HTC Touch Pro2 OEM (1500 mAh) battery? Does it make that much of a difference?
I read the findings on batteryboss.org, and it appears that the TP2 battery was better but the Seidio battery they tested was a used one, so it wasn't a fair comparison.
Any thoughts/help would be greatly appreciated. Thanks.
Loose atk....and read. I get a full 18 plus hours and I don't bump charge. Lots of info out there

I purchased a 2150 mah battery from verizon and i can say I wont be having battery issues.. that is one option, but you wont find a case that fits your phone, that is the only downfall
I was just reading reports about the new Facebook app...looks like they are working on that fix if you use that and it is causing a battery drain
http://www.androidcentral.com/facebook-confirms-battery-drain-latest-android-update
Uninstall the 1.3.0 facebook app RIGHT AWAY if you downloaded it. That destroyed my battery life yesterday and I have never had battery problems with my DInc.
You can just use the regular HTC Facebook app until an update is released for the facebook for android.
Try it without the new facebook for a day and see if it changes.
If you don't have the facebook app then just make sure bluetooth, gps, wifi are off when you aren't using them. I recommend trying bump charging but I've never personally and my phone lasts about 26-28 hours+ with mild to heavy usage depending on the day.
-Flawless
Thanks for the replies..I don't use Facebook so that wouldn't be my problem.
I think ATK is good.. I mean I don't have it on auto so I sometimes just kill all tasks and I have noticed any decrease from the already poor battery performance.

Ionno what it is but I'm running froyo 2.2 n I Thot this issue would be addressed but still nothing.. I'm hoping the VZW push will address it... I get decent battery life when I charge fully then turn off then plug back in til light turns green but its a pain in the ass to do dat.. I believe my awake time is like 3-4 hrs with an uptime of like 18-19 hrs

I have a Sedio 1750, which I bump charge every morning, and UltimateJuice set to turn on APN every 5 min for 30 sec or until data transfer is done. WiFi is used whenever possible and otherwise turned off.
I easily make it through the day and have battery to spare with moderate to heavy use.
All the battery life horror stories make me wonder what everyone is doing differently. Haha

This is the answer.
It's a battery. By definition it holds a limited amount of power.
Until they invent a phone with a matter - anti matter reactor that can keep it powered on for thousands of years before needing a refueling, having to plug the phone in every night is just a reality. And that day is far off because the price of the Dilithium Crystals needed to harness the matter - anti matter reaction is just ridiculous.

After 8 hours of heavy use you still have 61% battery? That is good. I'm normally down to 18% after 8 hours of heavy use.
You even stated that you don't lose power with the screen off.
Why don't you try staying with one ROM for a while and see if it settles? I posted a pic in another thread asking about VU battery life. I was just over 17 hours with about 50% left on battery. It was a weekend and I didn't use my phone much. It just sat idle with WiFi and Bluetooth on if i wasn't talking to someone in the phone. The screen was off for the majority of the time.

You got real suggestions. There was nothing left to be said after the real suggestions.
The real suggestions were and are to accept the battery use you are getting because it's pretty good. The only way you are going to see much better battery life is to invent a new kind of battery.
Now either accept that an enjoy your good battery life or be miserable about it somewhere else.
Oh, I just figured out some of the OP! Had to put punctuation where it belongs to make it a clear, coherent thought. They unplugged their phone at 9:30am and by 1:30pm it only had 61%...
I thought they were saying that they unplugged at 1:30pm and would be at 61% around 9:30pm. Which, from their own description of use, would be phenomenal. But even what they are getting is good.
Maybe if they used correct punctuation and paragraph breaks it would be easier to read and understand what they are trying to convey. It would be one thing to use a bunch of acronyms and shorthand, but periods in the middle of sentences and none at the ends makes what they wrote very hard to understand. The area where extended battery is mentioned is very confusing. I read it as the extended battery was "Showing 130% right now, unplugged; and by 9:30 it gets down to 61% with very heavy usage".

[Q] Nexus 4 on order, arrival soon, what can I expect ;) ?

So, they have apparently sorted out the stock and supply problem. I <cough> borrowed the wife's credit card and have placed the order.
They say it will ship in 1 to 2 weeks, I can live with that.
The light-hearted question I have is, once I've gotten over the excited rush of playing with the phone for a while, what have your experiences been? Good or bad! I've heard that the battery life is not great but to be honest I am not so bothered with that. I have a charger and work, and home, in the car - I can even charge it at the pub/bar I go to
Keep an eye out for issues worthy of an RMA. From there, the only thing to expect is awesomeness. You'll want to calibrate the screen color and gamma, though.
Has battery life been that bad? Because I just ordered one myself to replace my wife's 3GS.

yes battery life is very bad on this device. in sleep/standby its great. but when you do something, it drains battery very fast. just 5minutes use and at least 10% are gone.

Utter tripe. You either have a rouge app, or you have the brighness turned up full or something else stupid.
I easily get a full day out mine with moderate use. It's about 50%-60% remaining when I get home in the evening from work.
I got around 3 hours of screen on time and a full 18-20 hours standby on stock rom with the usual useage of whatsapp and gmail syncing, with web use and texting etc, and now on custom rom, I am getting up to 4.5 hours screen on.
So, battery is good, phone is super fast and smooth, camera is great if you take time to learn how to use it and especially with HDR on and a bit of post picture editing. Only down side is music volume and quality which is average at best. In my opinion.
Thanks for the feedback. I just hope my wife can make the transition from iOS to android.
I think depending whether you are on WiFi or HSPA will make a huge difference for battery. From what I understand, when using HSPA, the standby battery life is horrible.
The screen is usually the single biggest threat to your battery. And the N4 can get 4-6 hours of "screen on" time depending on use. As others have said, it can be on standby for 15+ hours, but you can completely kill the battery in 4 hours or less if you are using a cpu intensive app.
Custom roms and battery saving apps can def help out though.
I ordered mine at 3pm on wednesday and it was with me by 3pm on thursday .. so slightly quicker than the 1-2 weeks they quote!
Unlock the boot loader, doesn't matter if you decide on staying stock or what. Having your boot loader unlocked right of the bat allows you to keep your apps if you do decide to root /flash.

You'll sadly probably find that the screen is *uneven* in it's tint (yellow probably) and brightness. Because it's uneven, "calibrating" will help a little maybe but will not fix any issues with the screen. On the other hand, with luck (which I wish you) you may find that your screen is pretty much perfectly uniform in brightness and tone top to bottom, left to right. (Check using the Mail app and minimise the keyboard) I've had 5 so far and none of them are acceptable to me. Otherwise the phone is truly incredible in use. Buttery smooth, responsive, great. The screen very generally is amazing too. It's just not even as it should be. Let me know how yours is - i'd be interested to know because if yours has good uniformity I'll order another. Good luck!

[Q] best rom and kernel for a long battery life

i don't care about gpu or overclocking my device.. all i want is to unplugged the n4 form charger and go working in the morning and at night before bad to put it back in the charger - without it dieing on my before..
i had htc sensation and it last all day for me, i'm now 2 days with the nexus 4 , and after 12 hours the battery is dead.
i'm currently using Cyanogenmod 10.1 18/2/13 nightly . turn off locations, and Facebook sync. using only automatic brightness (witch my the way is very low), WiFi and gps and Bluetooth always off . 3g on.
thank you!
Usage varies across any ROM/kernel combo. No one can really say what's best, because everyone's usage varies. But, I can and will say, I'm having best battery life so far using asylum nightlies with matr1x 7.0 kernel. I have a very strict setup which I'm not getting into, but I am in no way limiting the function of this powerhouse. If that makes any sense. Currently sitting at 63% with almost 3 hours screen time. 50/50 3g/wifi and heavy use. think streaming, gaming, downloads. It would take me a very long time to describe what I do to get this battery life, but I would be willing to explain if needed.

I recommend AOKP build mr3, and Harsh's kernel. No need to tweak anything, everything is done for you and you get great battery life. Just my experience from it.

I'm using paranoidandriod with Franco kernel. I get great battery life all the time every time. Download the kernel and leave the settings as is and let it do it's thing.
Note: This has been asked too many times. You can search up the old ones and you'll pretty much get the same answers that it all depends on what you do. Battery life is subjective. It depends on the user. If someone only uses their phone for calls and text they will get awesome battery life. If another person has the same setup as the first they did play lots of game and play videos and such, battery life would not be so great. Thus, both users will tell you different answers.
Just try them out and see for yourself.

Is this normal battery life

Hello I just got this phone the Friday before Christmas and I've heard and read this phone has great battery life. But that's not what I'm seeing. I'm getting like 8 hours with moderate use on a single charge. Here are some battery usage information screen shots. She my question is this a defective unit?/should I exchange it? I'm rooted with the volume boost mod too.

Thats some pretty high temps you would see on gaming use. Something in system ui ect is demolishing your phone. Use WLD or BBS to find out what is keeping the system awake and using that much resource. Its probably software related. If you can't figure out what, perform reset. Not normal at all.

Hey you finally got the ls980! Congrats!
Are those g2 screen on hours for heavy gaming or video streaming tasks? Stock rom has a lot apps services draining battery, but you can easily remove a lot of bloatware as well as those apps you never use.
Debloat and debloat, you'll see g2 battery life is great!
