On the normal cyanogen releases and the nightlys I'm getting six hour battery life.
In WebOS I have fantastic battery life but I prefer Android.
I put HBOOT and whatever you require for Android a long time ago so is it possible I'm just not updated?
I really want better battery life, I'm thinking maybe there's a kernel or hboot or recovery I could flash that might help or something, because I love android but just can't stand charging in the middle of the day with mild use.

Haha, wish I could get 6 hours out of mine... I have it OC'ed to 1.78Ghz, both cores forced online, performance governor, and screen brightness to 100%... it dies in about 2hrs.
Consider yourself lucky you are not bothered by lag or dark screens as much as I am...
Love my TouchPad, but it I always keep it plugged in if my hands are not on it at that moment.
My daughter gets pretty good battery life out of mine watching Netflix or movies in VLC. I know I'm using an older version but don't recall which off the top of my head.
I know I've gone in there on multiple occasions and she'll have fallen asleep while Netflix is constantly streaming new episodes. Easily 8 hours later with still 1/4 charge. It sits on the stand charger when not in use.

if you customize the settings you can easily get more battery life than you could in webos, simply because you can change settings in a nice custom android rom version that you cant change in webos. everything from the wireless scan interval, wireless tx power using iwconfig, tons more processor power options, you can setup power profiles in most every overclocking app, tell the device how much power to use and when to use it. youre just gonna have to start learning how things work in android.
I am averaging 17-18 hours between charges using CM9 (August 19).

You didn't mention what ROM you are using or overclocks or usage?
Are you saying you, with constant continuous use, you get 6 hours? Or do you mean 6 hours between need a charge, idle & periods of use?
If it's the first, then that is not bad for constant usage, consider:

Several games for kids my daughter uses and at least 2 or 3 hours of Netflix for her watching her stuff.
My TP is in my hands the vast majority of the day. Take it off the Touchstone when I wake up and don't set it back til I go to sleep
Sooo if your only getting six hours of use I would recommend doing a COMPLETE wipe of webOS and Android to rule out software and also get the Touchstone charger if you don't have one... if that doesn't do it then I'd say you have a failing battery or an internal charging issue
And yes I can watch 6 hours of movies in a day... usually more like almost 9 if I knock down SetCPU to not go over 972

I figured I'd make this its own thread after speaking with several people with the same problems using a CMOD 5.0.5.3+ rom. This wasn't a problem in lower editions from what I can remember in testing.
Idk but I believe it is something in the kernel affecting this problem with the display hogging my battery. Even after flashing an undervolted kernel I still can only last 24 hours with an extended life battery, vs a weeks time before. And the display problem has been like this in all CMODS test .6 Roms as well so idk if it is in the process of getting fixed or simply overlooked. And other Rome work well but are slower it seams.
The display settings doesn't matter auto or manual its about the same. So devs what can we do to find the change or what can I do to help?

I'm running test 3 of 5.0.6. Today i read a book with fbreader for around 2hrs on it whilst on the train, had 2 30 minute phone conversations, around 20 texts, a dozen gtalk messages, and played blackjack for about 20 mins. i'm also using pershoots OCUV kernal, and after 11hrs without being plugged in I am at 75% battery. I'm happy with that.
I think it is a work in progress, as each new build comes out it's better. His testing builds are just that - testing. None of his release builds I have ever had an issue with either, although maybe my phone ue is a lot less than others I dunno. All i can say is i've never been tempted with another rom since early days on my magic phone Cyanogen rocks!

Nope, I have it on auto-detect, so quite bright when on the train and outdoors. I have setCPU (market, paid) running and set battery profiles - although I haven't hit them yet. I have it set to max 1.1ghz 100% to 50%, 998mhz from 50% to 40%, 776mhz from 40% to 30%, and under 30% to 500 and something.
I do use an app called autostarts (market, paid) and have set everything but system services/apps to not run on any kind of state change or startup. I use Advanced Task Killer to kill apps as soon as I finish with them.
But i've had all these for ages, I just think a big improvement on the last release test 3
Nandroid your existing and try out test3.
I've been experiencing the same symptoms with my battery usage generally dominated by the display. I'm using a UV kernel currently (intersectravens) so we will see if the same happens.
KingKlicks's DESIRE rom doesnt have the same problem it seems and the battery usage is much better.
Wondering if there is a underlying issue.
after .6 test 3 the battery has improved decently, still the display is hogging battery life more so than in the sense rom
Same thing here... Display totally kills the battery with CM5.0.5.3 and OC/UV kernel. Phone rarely lasts over a day with moderate to low usage...
Without usage I can barely get a days use :s
I get the impression that its not the display. I can have 50% display usage, sleep my phone while playing a MP3 and then have more than 50% usage... suggesting that its either he display+something in one category , or there is a bug.
The stock ROM always showed display at the highest usage also. I'm not saying that there isn't an issue, but remember that those numbers are all relative.
I'll say this: I charge nightly to prevent my battery "deep cycling"....That being said I un-plug at 8am and plug-in at about 11p-12a, I use my phone a TON.....usually when I plug in I have about 45-55%.....Not bad at all.....
I originally thought display being the main battery hog was a bad thing.....Then I thought about it a bit......
Would you rather the "system" use more batt? Cell Stand by?
Display (by all rights) should use most battery. More usage=Less time with a fully charged battery.....
Im using CM 5.0.5.3 and I switched Roms after using the stock for 3 months. As soon as I moved to CM I immediatly noticed the battery life was lower than before. I hope you find an issue to this problem ASAP.......I love your ROMs CM, but I love my battery life even more
Good luck with this !!
"display" = gpu acceleration and actual amoled power
Something else i just noticed, very odd. I had 41% display and 23% spotify.... i had been playing for music for a while (offline only). When i quit the spotify app... the entry from the battery usage vanished and display took a spike to 65% ish... really odd. Almost display is showing usage for a group of things.
What? How ? I get 6 hours maybe 7 if I'm lucky out of my battery.... even b4 my nexus was rooted ... how r u guys gettin 24

Ignore any figures people quote - battery life is always relative. One persons 'usual' usage is different than yours. A friend of mine brings his N1 to works and it sits on his desk syncing email - he gets 1 full day.
I bring mine, sync 2 accounts, play a lot of podcasts, have a RSS syncer going and use twitter and FB loads, i get a LOT less.
Dont worry to much, your usage figures are pretty normal depending on your usage patterns.
They say your mileage may vary for a reason
Battery Life
My Battery life has always sucked. Maybe I should buy a new Battery?
If I take my phone off the charger at 7:30, and don't plug it in all day, then I will be at about 30% or less by the time I get home at around 5:30. Unless I don't use it. But I use my phone to play stream music pretty much all day. Or at least 4 hours. One day I forgot my USB cable and I was below 20% by 3:00.
It is still better than iSuck, I mean iPhone, and worse than a BlackBerry. I have electricity everywhere though, a car charger, and an extra battery is like 25$?
So what is the big deal? You have the equivalent of a desktop computer from like 2002 in your pocked running off of a batter the size of a credit card, how long do you really want the thing to last anyway?
I'm trying to find out how lots are getting great battery life on roms and kernels that I get terrible or ok battery life. ex. Simply Honey with talon gave me the best bettery life out of any rom or kernel, but unfortunately that rom was not stable on my phone.
So what are some thing you do, and be kinda specific, like if you undervolt how much, and on what frequencies did you do what. Also helpful to include ROM and Kernel you use.

AHHH I knew that page would come up. I've probably done most of the tips and tricks and what nots what tos, but still get less than I should. That's why i want to know what everyone else is doing because I still can't get good battery life and simply honey is the only rom I got at least 20 hours, and that's without doing anything to save battery. I know there's more than what the guide has, and probably more difficult ways but I'm beyond the difficulty at this point, nothing is too difficult anymore.
My setup is toxic 8 with Bali 1.8.8 UV along with juice defender. With that and the extended battery I am able to watch a 2 hour movie using TV out and my battery only uses about 10 to 15%. I've never seen such good life until I started this rom/kernel. Now every time I try anything else I always go back to it. then with juice defender added too it it seems to last forever, if I didn't use mine so heavily I could easily get 3 days on it. My brightness is always set at max too. When I used to have my phone at stock I couldn't even last 5 hours with how I used it, after those few things I get 15+ easy every day.
Hell, I remember not even having my old flip phones being able to last as long as my vibrant does now.

See that's the one that gets me the most Bali, everyone says they get great life and that's the one i get the worst. I even undervolted -75mv on 1ghz and 100mv on the rest down, used only network data, auto brightness (love it) etc. and just barely using it maybe 1 hour of talk and 2 hours of music through speaker dead in another 3 or 4 just sitting there. Now i didn't know about juice defender before and I'm trying that now. I'm on ICS Passion 10.6 now was on D9 and Toxic8. I get a little better battery on passion over D9 or toxic8 but maybe and hour more.
Which profile do you use in juice defender? Don't see so far any improvement on balanced.
Juice Defender itself works great but if you really want to see what it does pay for the Plus (Ultimate has more features that the Vibrant just doesn't have, so no point in buying that unless you are moving on to a new phone someday).
One of the features of JD+ is that you can configure it on an app to app basis. So if your screen is locked it will kill something like Wootwatcher.apk but not Pandora b/c you presumably are listening to it. No need for Wootwatcher to be running all day long, they only update it once a day, know what I mean.
Another thing is what IS running in the background? You can use the BetterBatteryStats. It will show you what and when and how long.
Yesterday I pushed it to 33hours with moderate use (don't forget I do sleep too). Heavy would be much lower but I've been busy at work so moderate was all she got. One of the features of JD+ is that you can kill the radio/data from x time to x time. I have mine set from 12-6am (but it you are using it in those times, user takes priority). I don't need to be sending data while I am asleep now do I.
Flashing ROMs a lot also kills battery but T8 and D9 are my home ROMs too.
Edit:: Maybe I should elaborate on the 33hours. Unplugged at around 630a Monday, Music on the way to work. About 20 texts and 5-10 calls, XDA app, Music for about 8+hours Monday and first half of Tuesday, some games here and there (Reckless Getaway, Scrabble, kids played some drawing games), some browsing, started a movie but got sidetracked (about 1hr's worth) and finally plugged in at around 330p on Tuesday. So that isn't heavy but it also wasn't just sitting on my desk either.
I read somewhere (probably androidcentral post) that @ night or whenever your phone is idle, if there is a wifi signal around... turn ur wifi on. For background data stuff that's running, this actually uses less battery than if you let your phone's data do these tasks!
Well to day I tried juice defender plus in my daily routine......... huuuuuuh but then I drop my phone and broke the glass screen. Everything else work my battery did get much better but I didn't really use it as hard as normal, mostly cause I sat outside in parking lot for 2hrs waiting to get in store for work, so can't really say its doubled for sure but 13hrs is much more reasonable. Did update kernel and calibrate battery yesterday. Might have had something to do with it. Gonna try some undervolting see what I can do there.
As for wifi, it's actually worse than network data, especially when its idle. I always keep wifi off unless I'm watching a video or dl'ing a large file, just too power hungry.
I like my Android Touchpad (Cyanogenmod 9 Alpha 0 Build) very much and i love every minute I play with it. But the real deal breaker is that the battery is dying like anything and within 2 hours all the juice is dried up.

What is your charging practice exactly?
I would normally charge to 100% and wait till it goes down to 0...at first it took around 3 hours for full charge but now its almost taking 5 hours go get a full charge

You know there has been a charge fix released like half a day after alpha 0 was released to the public. In fact the newest build is now 0.5 alpha, which makes your issue a problem of not updating. Seriously though, update to the newest build.

Are you serious? These batteries degrade with each charge. Constantly charging is a bad idea.

Thats odd... I can go days with my TP on one charge... I don't use it during the day (at work), but it's on, screen off. I used it alot at night and read before I go to bed, but just turn the screen off. I also bought setcpu and have some profile set up so when I don't need the computing power I underclock it and when I need it I overclock it. Do the same with my phone and it really extends battery life.
I'm seeing really good battery life with A 0.5. I saw good battery life with A 0 too, and evervolv. Like 6-8 hours of screen on actual browsing use. I see almost no battery drain with the screen off. I can easily go a few days between charges. I don't know the charge time because I have a Touchstone. So, when it drops to less than 50% I leave it on the touchstone overnight. I use the app dock nothingness so that it won't wake up and keep the screen on.
Check you don't have any apps preventing sleep. BetterBatteryStats should identify any apps causing a wake lock. CPUspy will also help you verify the CPU is entering deep sleep when you turn off the screen. The very first build had a wake lock that wasn't caused by any app, but the charge fix fixed it. I noticed on the very first build the light on the button of mine was always on, even with screen off.

I'm afraid you're incorrect.
Allowing a lithium battery to repeatedly go low will cause serious damage and pull down usable life and capacity.
Constantly charging to Max and the monitoring circuits will take what's needed and no more so you are only putting back what's used.
It's not charging any more than you use so there is no added degrade.
Plus if you have the device on charge as much as possible then the cells attain their max capacity.
About 3hrs with CM9, from full charge. Wifi and display pull all the juice.
I would reflash and start from scratch. Sounds like a process going rogue, I get 12 hrs or so on a full charge reading and browsing.

I have no idea how to explain your situation but I know my battery life is better with CM9 than it was with CM7 - and that wasn't bad to start with.
for me battery still working good, is holding all day whit the wifi, no using hard way and in sleep mode i can be 2 days whitout chargin, i just use it to browse some webs
There's been mixed reviews of battery life in the CM7 rom for the NT as far as battery life is concerned, some are saying they've run it with moderate use since the day it was released and only used about 20 - 30% so far while others are saying battery life is terrible.
SO I thought I'd start a little poll to see what people are getting, I'm guess the battery drain is due to various software being installed so not really the OS's fault.
For me the Battery life is greatly improved over stock, for instance I took it of charge 10 hours ago, it's admittedly only been used for a few minute son and of during those 10 hours but it's lost the grand total of 4% battery in those 10 hours which I consider pretty good really.
Soi lets here what everyone thinks, remember to vote !
Battery life - improved
This is my third day on the CM7 alpha - battery life has been much better than before. Considering I have probably spent more time with the NT turned on over the last couple of days than I normally would, the battery used is less than normal. Previously I would use about 60% of my battery per day. Now I am using 30%-40% - and that includes downloading and configuring many, many applications.
I really think its much better than stock in my cm7 nt
No problems here. Take off charge around 6am and return to charge around 10pm with usually more than 80% left depending on usage.
Sent from my Droid Incredible ICS 4.0.3
I don't think mine has been on a charger for the last 16 hours or so, light usage, wireless has been off most of the time, and I use a task killer to kill things before I turn off the screen. Didn't power off, just put to sleep last night before bed, it's still at like 85%.
So far, it seems better than stock battery life to me, or at least no worse, and I have a lot more apps installed now.
Edit: Internal version.
It might help if folks said if they were running off SD card or internal memory when looking at battery life - I have the impression that the SD card reader on the NT is something of a battery vampire.

Odd. Is that your aforementioned case with lots of standby? On my Vibrant, the Screen bar generally dwarfs all other bars even with significant standby time. Granted that's an apples-to-oranges comparison... (I don't have CM7 on my Nook Tablet yet - can't do a comparison between stock B&N and my Vibrant at the moment.)

Yes. I don't really know what "standby" means. This use was about 40 minutes of checking email, weather news and etc followed by About 2 hours with the screen off then an hour of dinking around. Watched all the superbowl commercials, staying up on XDA and other forums with Tapatalk and learning things in CM7. I'd describe this as light use bordering on moderate.

Watching video or playing games can be quite intensive. Flash is probably the most intensive for video playing.
Keep a good eye in it over the next few days then cone back and post if you've noticed anything that makes it better or worse with battery life
Last I checked mine was going on 18 hours and at about 40%
One thing I noticed is that the charger for my Moto phone doesn't seem to charge the nook as well as the nook charger. I'll have to look at the nook wall wart and see if it's pumping out more juice. For reference the Moto charger is only 4.33W (5.1V at 850mA).

What kind of usage? Low, high, moderate? Just curious because my wife and I do a decent amount of Netflix (1-2 hours a day) and I don't have to charge more than every 3 days. This is with 1.4.0 rooted. I've been exceptionally pleased with that - power consumption in standby seems to be incredibly miserly with stock (most likely due to WiFi being turned off when the system is in standby).

Ahh. That explains a lot. Looks like I should pack that in my bag rather than my Moto charger. I wonder if it'll charge my phone faster?
On the subject of the battery, I posted about an issue I encountered last night, here:
http://forum.xda-developers.com/showthread.php?p=22261812
Additional information: At the time, I was fooling around with a playstation emulator, which i'm fairly sure constitutes a heavy drain on system resources. Battery drain seemed appropriate for the level of activity.

Internal install, wifi off during sleep. Figure the end of the graph was about 19-20 hours or so of sleep. Before that was a constant internet, twitter, WWF session. Screen brightness is in the bottom 1/3rd of the slider.
I am going to beat the hell out of it tonight and will see how the battery holds up. Looks pretty solid just sleeping, so we will see what it can do under load.
So found that if your wireless location is turned on, it will wake your NT about every 5 minuetes. That's not a good thing
If anyone is seeing drains, i suggest using betterbatterystats to help track down the culprit.

So Im getting horrible battery life with this now. Not really sure whats going on. I use to be able to leave my nook on standby for days and last night it was at about 30% woke up this morning and it was completely dead...
Hi all
This is my first post, so let's hope I've gotten it right and am abiding by all the rules and the n00b video. And yes I did search for a good 10 minutes about batterylife and battery before posting and didn't find anything relevant.
I've recently swapped over from Apple iPhone and I'm now very much enjoying being on Android. However batterylife is a big concern for me, as on iPhone I could go 2-3 days without charging and now I can barely make it home from work and I definately have to plug it in before dinner. And yes this is with me closing down applications, wifi when not used, bluetooth when not used, running latest kies released PHONE:LFB firmware and so on.
So my question is... how is your batterylife after having rooted and installed a custom rom? The one I'm thinking mostly about using is definately the new Preview 3 (or perhaps wait for 4 or 5) of CM10, that XpLoDWilD is working on. Does anyone have any experience with the batterylife before and after?
Thanks a lot for any help you can provide! :highfive:

That's very weird. Are you international or a US S3? I easily get 3 days battery, very easily. Perhaps try turning off useless stuff like bluetooth, gps, wifi, etc when you're not using them. Turn off push email and other useless crap. See how it goes then?
I still have the stock ROM, usually 3.5 days battery before it gets to 10% and i charge. I'm going to go to OMEGA rom soon though.
I have tried almost all custom roms out there. And I can easily say the battery life is not any better if not worse on custom roms.
Stick with the stock rom. I would however recommend flashing a custom kernel like speedmod or phenomenal. They definitely give you that extra juice you need at the end of the day. The idle time and screen time has increased for me 10 to 20 % compared to stock.

I'm using the international version. I did turn off bluetooth and wifi, but not gps. Will try that aswell. I have manuel mail check every 1 hour, but will try to set it to 4 hours.
However from what I read in the reviews on GSMarena and other sites, it's quite normal to only get 1 day worth of battery.
Description of a pretty basic day with the Galaxy S3:
I usually unplug mine at 6 am, with wifi and bluetooth off and screen always on auto brigthness. Then at 7 am i turn on bluetooth for my earphones and bike to the train station and browse the web and such for about 45 minutes in the train. When I arrive at work it's usually around 80% battery and I turn off bluetooth. Then I'm at work from 8 am to 4 pm and check mails, texts, calendar and possibly make 1 or 2 short phone calls. At 4 pm I think the battery is often around 40-50%. Then again on the ride home I use the same, so it's usually around 20-30% when I come home. I then usually turn on wifi and play a couple of games, or watch some Netflix on it while I'm doing some other stuff or attach it to my stereo and play so music from Spotify on it. At 6-7 pm it's usually beeping at the 5, 10 or 15% marker for more power and wants me to plug it in to a power source. If I try to wait till I go to bed, I usually end up having it automatically shut down from lack of power.
I'm wondering if this seems normal or if perhaps my battery is faulty. From the review at GSMarena it seems quite normal and that's just the way Android is. They even gave it a good battery rating inspite of saying that it would only last them a day.

Okay, thank you for your reply
it all depends on the usage i have an iphone 4 as well and i have to charge it by the end of the day (at 10pm). So it dpends on what you do with your phone if you use 3g all the time thats not gonna last long if you have syncing on all the time and gps that wont help...if you just let it idle then you can get 3 days uptime with maybe 1 hour screen time.

My basic day is charge the phone at around 8pm, unplug at 10pm. I never charge overnight it's pointless (not that i think it'll hurt it). Wake up battery is usually around 95% after my alarm goes off. Brightness is about 60%. I don't browse the web very much, and I don't play many games, let's say 1 hour of web and 1 hour of games/videos/music per day. Maybe 1 hour of maps too. Mostly though, I text message and phone call.
I don't think yours is faulty, i think it's quite normal, it seems like you're a heavy user, I'm a light user. If I used my phone as heavily as you did i'd be happy with 1 day of battery.
One day of charge (the battery being at 20-40% at the end of the day depending on the usage) is quite normal.
I've found CM9 with Siyah to give the best standby battery (1-2% drain per hour with 3G and Sync enabled) since it's very lightweight and has no battery-draining bloatware other than what you install.
CM10 is still too new and unfinished to be battery-friendly, it's not that bad though.
However sometimes it will chew the battery for no freaking reason (at least I cannot found any) and the CM9/CM10 stock kernel is not that battery-friendly on active usage. No Siyah yet =(

No way is that good man, that means that if you leave it on standby alone you lose 25% per day. 0.5% per hour would be good/normal IMO.
