Ok, for the first week I had my galaxy s2 my battery would be like 75% after low usage. Now after following the root guide. Then updating it to entropies DD I have terrible life. It seems like even on light usage I lose over 10% an hour. I can't say for sure when it happened. I want to say it wasn't immediatly after the root, but within a week of it.
Here's a pic of the battery life:
Well there would be a pic if I had enough post to post a pic. Anyways it shows my android OS using 71%
It shows that I have a 41% charge at 7:15pm after an hour charge from noon to 1pm that brought it upto 75%. The only thing I've done is text the wife half a dozen times.
Is there anything else I need to log or post to help troubleshoot this?
I love having my phone rooted, and I would hate to have to flash back to stock if I can't get my battery issue lined out.

Nothing to troubleshoot really. You probably have most of the known battery draining apps runing on your phone. (listed on another thread)
I would suggest you flash a ROM like Unnamed that removes all the bloatware and all these battery hogging apps. I would also get an app like Setcpu to set the cpu to conservative to save even more battery.
Good luck!
Entropy's DD already sets the CPU governor to conservative. Anyways, post a pic of your battery usage (by uploading it then linking it), and if your phone has blue bars all over awake, then you know you have a wakelock problem. Search for the known battery drainers thread and see if you have apps there, also remove all widgets and add them back one by one to see if any of those affect battery life.
Battery
It's just common sense, before rooting a phone like the i777 it's not much fun spending a
lot of time playing with it.
But after it's rooted and we have access to the CWM Recovery ready to do our bidding
we all get carried away by all the fun and interesting things we can do with the phone
if you get my drift! (and it's easy to get carried away with a phone like ours)
I just don't understand how so many people can say that "My battery is great" or
complaining that "My battery only lasts xx amount of hours" with a straight face
because just like any other battery operated electronic device, our phone's battery
consumption is a lot more variable than the weather!
Without conducting tests like starting with a fully charged battery keeping the screen
on until the phone goes dead or playing non-stop music until the battery dies there is
no real accurate way to test battery life unless it's done under labratory conditions.
Otherwise all we are doing when talking about battery life is a big guessing game!
Even little things like the ambient room temperature and the amount of moisture in the
air have an effect on battery life in all electronic devices even if they are powered off.
In other words, simply rooting a phone and doing nothing else has no effect on the life of the battery.
Hey I think you should try to wipe your battery stats in recovery after ah full charge cycle ..then let it discharge then fully charge it again. It worked for me after flashing cm7 on my evo.

Battery stats should not be wiped on these phones. There are threads that discuss why not to do that in this forum.

Entropy has repeated it in detail time and time again why there's no advantage to doing it and while it works fine on other phones, it doesn't with ours. If I can find a link of his, I'll post it later.
Well, this question is for my lucky friends who have their new toys
Battery life is so good?
Post your test here!
Don't have screens for ya but battery life is more than adequate. My gf and I used it for about 5 hrs last night and it dropped to about 45%
(Games, xda, Netflix, and just tinkering around)
I'm curious what kind of battery life you folks are seeing, now that you all have had time to get some real world experience with the NT.
Thanks!
10 hours of continuous usage with 25% brightness.

Yea, the battery life and responsiveness of the device is definitely top notch.
I'm pissed as hell the bootloader is locked, but this device is an absolute steal for $250 bucks. Especially if you can manage to discount that price down.
Extremely responsive and awesome battery life considering I'm running max brightness and wifi 24/7.
I'm always surprised when I'm done using the Nook that it was still running. Granted, I ran it until it had only had around 20% left. But hey, if your sitting in one spot using your nook for more than ten hours, then you need to find something else to do. ^_^

Good book, nice day, under a tree? Done that many times just reading off my PDA.
Thanks for the feedback!
The battery life is definitely adequate.
I can usually go 2 day without charging thus far. I keep brightness at ~20% or so (I can't stand brighter, it actually bothers my eyes).
I also use multi-picture-live-wallpaper and it doesn't seem to drain my battery at all.
I do some pretty heavy use of it as I am reading on it and studying for med school for probably ~6 hours at a time
Battery life is great. BN's numbers seem dead on.
Lasted the flight from San Francisco to Sydney
I'm getting around 10 or so hours of use at 2/3 brightness. Battery life is amazing on this. I charged it last night. Took it off the charger at 10am didn't touch it till 10pm tonight. It was at 99 percent then. I think it turns off wifi when it's sleeping.

Yeah, it definitely turns wifi off on its own when sleeping
Yeah Ill echo the comments here, battery life is absolutely superb and the responsiveness of the unit for the price is fantastic. Sadly its a case of if only B&N....to fully realize what the tablet would be capable of.
I have to agree that battery life is amazing on this thing.
I've got wifi turned off full time (to avoid updates from B&N) and the battery just seems to last forever. Granted you always use less battery when you're not going online, but still, it seems to really really last.
Frankly it's making my phone quite jealous.
Umm, my nt's battery isn't as impressive as i hoped. I use 25% brightness, wifi on, no fancy live wallpaper. I noticed for every few minutes of sjurfing, battery would drop a percentage or so. For usage of about 3hr withoit wifi, i would use up about 40 %.
Anything i could do to tune it up a bit? I do noticed amazon appstore is always running, so is clock, contact, tb, and my yahoo mail app. Any help is appreciated.

That sounds about what I'm getting and I'm wondering whether it's defective or not (still within return window).
edit: Probably normal - ran into some threads on B&N's boards where other people are averaging 5-7 hours. If I idle / read, I get about 1% every 8-10minutes or so so B&N's time estimates were definitely not "video," "browsing" or "games." Wifi on, installing or rebooting a few times, it drops to 5-6 hours tops between 100% and close to 0%.
My phone gets -way- more time, even reading.
the battery on this is great one of the biggest things going for it. better than my phone for sure.
For you guys with bad battery life, you might want to try better battery stats. Then check for partial wakelocks. That's usually the culprit on my phone. It seems weird some of you are getting half the battery life of the rest of us. Personally I haven't even turned wifi off at all, and also haven't turned my brightness below half.
It's in the google market, it won't show up on the nook. I downloaded it on my phone then used the app share my applications then back up to sd. Upload to dropbox. Then download it with dropbox on your nook.

I looked at this (and other battery programs), but wasn't sure what they did. Now I sort of do. I'll check it out! Wifi on definitely uses up at least 20-25%ish extra battery, and I *have* been moving a ton of stuff to/from sd cards and uninstalling and rebooting a lot, but the above did seem very short. Too bad there isn't a battery hardware test
Failing those applications it may be worth doing a full reset; Especially since most other owners are reporting MUCH better results.
Before I start nuking things around, I used BetterBatteryStats, check for partial wakelocks, and the highest % is from ActivityManager-Launch, which occupies 0.3% or 5minutes or so since I fully charged it.
Also, i noticed "Wifi Locked" is extremely high, like 89%, whereas wifi On is only 26%. What does that mean?
I'm not fully versed in how Android handles power management. So what should i be looking out for? Thanks!
Hi all
I know battery life has been discussed quite a bit, but Ive found most, if not all, discussions are "runtime" battery life, not standby..
For me Standby is important as I dont use the TP that much, but when I do I dont want to see the battery a 25% or lower!..
Currently webos 3.0.4 seams to drain around 5-7%/day, whereas Android CM7Alpha3.5, and Xron b2.1 appear to be about 20%!!
I know this is still alpha, but this , and only this, issue is stopping me from switching completely to android...
Any comments??
ps Dont get me wrong I know this is alpha, and the CM & Xron guys have done WONDERFUL things, just thought Id ask..
Anyone tried the new Miui build?? is it based on CM7?
Will CM9 be better considering its Android 4.0 "built for tablets?"
thanks all!
i mean, basic phone stuff still applies here. turn off wifi, etc. certain apps will kill your battery more than others (ie scrabble), even when idle.
idk, i find that it's easier to just shut it down completely if you know you're not going to use it for 8hrs or longer. i leave my tablet on all day when i leave for work and come home to see it about 10% lower, but i don't pay much attention to it.
I been at work all day long 10:30am - 9:00pm... I didnt have time to use my TP at all during any of my breaks so it was in standby the entire time.
When i finally got home and turned on my TP it was at 92% out of the 99% it was at in the AM.
Running Xron 2.2, i cut it down to 130mb, not a single problem yet since I installed it.
Hi guys,
good comments!
@thekillingtree : Yeah powering down is one option, but the beauty of a tablet, you keep it on standby...
@jzen : mm thats not bad, however 11hrs=7%, therefore thats about 15% over 24hrs...
Yes I know "things will" drain the battery when in standby when running in the background, i suppose Im comparing it to things like an ipad (less than 1%/day drain in standby), webos which is ~5%/day in standby and even the NookColor (v1) can go for 2-3 weeks in standby..
anyway, its still alpha for me Im hoping standby time will improve when it goes beta etc..
for now I'll simply keep it "topped" up!
Angelo
i'm genuinely curious how long the standby life will be. i fully charged my tp this afternoon and i'll see later how low it is.
i never really cared since i charge it every day or two.
Firstly you have to remember that the battery status monitor in android is all over the place and can never be accurately relied upon.
Flatten the battery (yes, I know it's bad practice!), then fully charge, wipe battery stats and leave alone until battery is flat again.
Then you get definative battery life, for your device/battery combo.
I know that when im done using the touchpad for a while.... i turn off my wifi.
the battery barely drops when wifi is turned off.
Idea: i wonder if installing juice defender will solve this issue.
--> Juice defender turns off radios and preserves battery life on my android
phone it might do the same on the touchpad. Just a thought i havent
tried it yet
good idea!
Actually yeah, juice defender worked a treat on my htc legend.. might help with the cm7 rom too
Sounds to me like it is not going into a deep sleep. I charged my tp fully last night, went to bed and woke up with 65%. I know this was an issue for cm7 and miui on my Droid x.

For this to be a meaningful comparison, you need to be running the same apps on webOS as you are on Android, and understand how the apps work on each OS (e.g., background processes, network usage, etc.).
The Touchpad has a 6000 mAh battery. According to Battery Monitor Widget (in Android), my TP discharges at about 40 mA while idling with the screen turned off. This is with wifi enabled and whatever background processes are running for the 150 or so user apps that are installed. If I were to just leave the tablet alone, it will drain the battery of 40 mAh in one hour. In 24 hours, it will have drained 960 mAh. 960 mAh out of 6000 mAh is 16%, so that's seems about right.
It's been a while since I booted up webOS, but I recall that the Govnah app will record battery drain as well, so you can see if the current is lower or higher with webOS.
I've had my Flyer a few months now and in the last few days the battery seems to be draining very quickly. I charged it full again last night and this morning it was at 88%.
I've turned everything off so just the bare bones of the device are alive and i'm using Juice Defender, and still no joy. It's only started doing this in the last few days so i presume the battery is on the way out very quickly.
I've let it drain to 10% and charged it, and it's made no difference.
I'm not going to mess about with settings and more waiting to see what it does etc...., I really just want to get a new battery and be done with.
Where can i buy a new battery? I've had a look on fleabay and no joy.
Any suggestions where to get one, part no. etc...?
Many thanks in advance

happened with me also....10% battery drained overnight...
what app is using most of ur battery?
sometimes push service in some free market apps drains a lot of battery and it keeps running even when app is closed... check running processes... well i uninstalled that app with push service and all became normal
Thanks for that but i've had a look through and it would seem that there isn't anything happening over night that i'm not expecting or that is being very hard on the battery.
I'm pretty confident the battery is the culprit here. Sourcing a new battery however is proving to be a problem. Somebody somewhere must be selling them.
I've just been on to HTC in the UK, they have a service centre not very far away from me and they won't sell me a battery or even give me a part no. for the battery.
Come on, somebody must know where to get one.
I think i might have found somewhere in China...

If the prices were cheap enough how many of you would be interested in buying a battery for your Flyer.
Perhaps do a group buy?
i thought flyers battery is not user replaceable?
It's very replaceable and easy to do.
Here......
http://www.techrepublic.com/photos/cracking-open-the-htc-flyer/6256123
I'm going to have to look at getting a new battery sooner or later. It's getting to the point hat the battery is always running low by the time I get home in the evening or even running out. With pretty much the same use it used to be good for a day and a half easily. Flyer was purchase may or june 2011 so it really needs to last another 16 months or so.
Well......I ask again. If anyone knows of where to buy an internal Flyer battery please post a linky.
I posted this thread earlier today
"I just wanted to know what people are getting out of their batteries. I unplug mine around 7:30 am when i leave for work. When I get to work i turn on my wifi (rooted thunderbolt) and leave that on all day. I have the setting to turn wifi off (flyer) when screen is off. When I get home around 5:30 i switch to my home network and by 8-10 my battery is pretty much gone. Is this normal battery life or are there any tricks I'm not aware of that will help with battery. My wife has an Ipad 1 and she seems to get days of use out of it before she needs to charge it.
Also, I don't watch movies or video at work... most of my use is surfing, twitter and email."
I'm trying to figure out if what is normal battery life and If mine came with a bad battery. If so Yes I would be interested in getting a new one.
The Ipad battery has much longer life and is a much bigger capacity battery. The new HTC Jetstream also has a much bigger capacity battery as well. I think HTC have learned lessons on how much battery power these flyers use, but unfortunately have used Flyer owners as guinea pigs, rather like the first Apple iPhone but that had terrible battery issues as well although they've gotten better over time.
When my Flyer was brand new the battery lasted for ages and i couldn't understand what people were on about the battery not lasting for very long. So up until a few weeks ago my battery was doing fine and then almost within a day or two the battery started to run down quickly and has been doing so ever since. I've since loaded/unloaded new ROMS and done all the usual procedures for deleting the battery stats etc..., and still no joy.
I think the problem is with the battery not being man enough for the job at 4000mAh, and the drain is such that the battery is being worked hard since September last year (in my case) to a point where it is now progressively failing. I'm not so sure either that it's all that good in terms of quality.
Most of that time it has been charging from one source or another. If my Flyer isn't in the car or in the house it's not often being used battery only unlike most other people probably use the battery only a lot, so i can't understand why the battery is failing when it's not even that old.
This is a big issue with the Flyer and for what the device cost i would have expected a lot better. I think the Flyer in itself is a fantastic piece of kit that i will no doubt keep for a very long time as i did my XDA IIi but i never had problems buying another battery for my IIi. HTC will not sell me a battery, they insist i send the device to them and they will swap it but will cost about £50-£60 for the pleasure. I flatly refuse to pay that!!
What is required is a bigger capacity battery (6000-8000mAh) in the same packaging as the current battery however, i think for now i would happily settle for another of the same battery if i could just get hold of one.
So far it's proving an impossible task!!
Just to add: Once you've made sure there aren't apps being opened at startup that don't need to be opened until you're ready to use them, also make sure wifi/bluetooth, mobile data is all off when not required, and all the usual tweakes to make sure animations are off, screen is on the lowest brightness etc..., then there is not a lot more you can do. I don't know how much use something like Juice Defender will be as that only makes sure your data connections are off at night and other times you specify. I've tried it and it didn't help at all so i don't know what else to suggest apart from turning the radio part of the phone off completely at night if it isn't on charge.
If i leave my phone off charge all night, having fully charged first, i wake up in the morning and it's down to around 86-88% battery.
I can surf pages with my browser or just go through random screens on my phone and watch the battery percentage go down every minute or less. Is that normal.
I have setcpu set to powersave and everything off besides wifI. I am on Saurons ROM and new kernel. I have brightness at minimum and I wouldnt hope the screen by its size alone would drain the battery that quickly? I went from 92% to 89% percent just typing this message. My usage on the phone says 57% screen usage and all other apps have 5% or less.
Any tips?

agreed
agreeed!! i have bad battery life too
I actually have decent battery with more than normal usage

everyones seems to very. i personally have great battery life at tims with mild usage getting well over 17 hours of use and 3-4 hours of screen time.
then are times when im playing games like osmose and it wont last but maybe 2 hours of screen time as that game is a battery killer.
but im happy with mine. check the other threads about this. people have posted many ways to conserve and help the bettery life of your phone.
