What am I doing wrong here?

Ok I got the X10 a few days ago.. loving it.. now..
How do I extend the life of the battery? I know theres a ton of topics on this but I can't seem to get more than 12hours..
- I use StartupAuditor and pretty much stopped most apps from running at start.
- I use ADW Launcher
- I use JuiceDefender
- Timeout - Screen timeout after 15s, lock after 2mins
- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)
- Screen - Leave APN/Wifi enabled while screen unlocked (So it disables it after it has been locked)
Any help is appreciated.

After a couple of weeks your battery life should get better with out you having to do anything. Just be patient and let it fully discharge before recharging. Also restart your phone after a full charge and after using wifi and gps.

force close the face recognition will save alot of power, face recognition sucks the cpu hardly!

Discharing a battery is bad isnt it?

Well your problem may lay here
"- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)"
Your using Moxier which other X10 users have identified as a huge power user and according to you, your also using APN/Wifi for a minute every 15 seconds..........so it's essentially never turning the APN/Wifi off :-S
Hope this helps!

Also fully discharging your battery every now and then is actually beneficial for your battery.

Quite certain the 1 minute every 15 seconds is a typo
Juicedefender defaults to 1 minute ever 15 minutes.
I removed ATK and Juicedefender, I found they only screwed up things in the phone and after removing them I noticed no change in battery life. (If anything, my battery life increased after removing ATK)
The best things for battery I have found to be.
-- Alternate launcher (I use ADW, I think Helix is better for battery performance but ADW has more options).
-- First 5 charges, discharge battery completely and do this again once every month or so
-- After full charge, power cycle phone (Turn off/on)
-- Use quick settings to turn off GPS, WiFi and Bluetooth when you are not using them
-- Make sure you back out of programs when you're done with them. This will close most applications so they are not running in the background. Certain apps (like a dolphin browser) have exit functions under more options. This is useful as back will just go to the previous page.
Note: Force closing applications which you see open in the background may use more battery as it may just start up again. Constantly killing and opening the program will use processor/battery power. Whereas many programs, when open in the background, are not using active process power and Android OS will pause/stop applications which are not in active use, by default.

Where can i find the timout setting for the lock?

Screen brightness turned down. Wifi instead of 3g. That's what I do. And I think I get around 15 hours. Still kinda bad. But better than nothing.

From my experience..
I find 3G has better battery life than WiFi, unless you are constantly browsing. When 3G is active, but you're not browsing the web and stuff, I find it doesn't use much battery. WiFi, however, uses up loads of battery when the phone is idle.

I want to know that as well Tried to find in phone settings but couldn't figure it out

Battery barely gets drained by wifi in idle state. you just go into wireless settings and set wifi sleep policy to when screen turns off.. should be fine after!!

As per my last question, discharging is bad isn't it? With these batteries, you have to constantly charge them so they don't loose life
Edit: Also.. if I press home button or back button that doesn't close the app.. most apps don't close like that, so I have to use ATK to kill it.. is it fine to leave apps running in the bg like that?
Edit: So I should uninstall ATK?

I also JUST got an X10 about 2 weeks ago! My battery life was so bad at first, and I ended up trying most of these battery saving apps. But to be honest, I found that they did more damage than good.
I now have everything I don't use turned off. Bluetooth, WiFi (when I'm not home at least) etc. Just skim through settings and turn off anything you don't think you'll use. And I restart my phone every morning and I get 30-50 hours out of it, depending on use. It is definitely getting better with time too.

For ATK, I would uninstall it as generally killing tasks does more harm than good. If you use it intermittently and only when necessary (and not use auto-killer) you could keep it installed.
As for apps running in the background..
-- If you press back, it should close most apps (not all, but well designed apps should)
--The Android OS is designed to pause/stop apps/processes which are not being actively used by the user and will close them eventually if left unused
-- ATK is generally only freeing RAM which is not important. It is not like Windows in the sense that more free RAM = faster speeds. It is a lot more like, more free ram = more wasted ram.
Here is a link to where I found out most of this information.
http:/geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
As for WiFi sleep policy, thanks for pointing this out. It seems that my phone is already set to sleep WiFi when the screen is turned off. I find this weird as I have found significantly reduced battery life when I turn WiFi on, even when my phone is mostly unused/idle.

Thank you so much Mobzter, but i was not after that As Sashi said that he has set "Timeout - Screen timeout after 15s, lock after 2mins", I know about about screen timeout but "Lock after 2 min", How? Thnak You anyway ^^

@mano. Good question. I can only find screen time out as well.

i have noticed some thing strange ,the phone lasts more with apps open in backgroung than when i close them . and using my phone consumes less battery than leaving it in standby .very strange phone (may be only mine ) any confirmation.

Hey Hoss,
I can confirm that force-closing/killing apps seems to be worse for battery life than leaving them alone. Backing out of apps usually will stop any cpu usage, but leave the app running. Killing/closing them will just result in more cpu power to run it when necessary.
As for standby vs usage - I have the opposite experience. The battery life on my x10 lasts a lot longer when I am working all day and not using my phone very much.

[SOLUTION] Found a fix for battery draining

This doesn't work. Ignore this thread please. Android OS and Wi-Fi Sharing reappeared after a few hours even though I was in bed sleeping and not using the phone.
For those who have problem with Android OS and Wi-Fi Sharing draining battery, this is for you.
I think I have found a solution. I need someone to try it out with me. So far so good. The main culprit is Kies Air. If you are not going to use it, please do not tap on that app at all. If you can, hide it. Once you tap it, it will remain running forever even if you shutdown and restart your phone. So what can we do?
First, Factory Reset the phone. Then, make sure you do not launch Kies Air after Factory Reset.
That's all. Now all you need to do is monitor the battery graph and let us all know your findings. You should not see Android OS, Android System high up in the list. Wi-Fi Sharing will no longer appear in the list that consumes battery.
I have success with this.

How long have you had it running like this?

why dont you just end the service in the settings?

I use Kies Air extensively. But it does not really keep running in the background here.
I dont keep my wifi on unless and until needed. SGS2 is very quick to get IP than my older phones, so i turn it on when needed from widget. Also you dont need wifi on before launching Kies Air. It will turn it on and off by itself.
when i close kies, it asks me if I want to disable wifi and it closes properly.
I tab of ATK and it closes on me never to turn back on by itself.
The only programs that keeps coming back are hubs and iplayer which to be honest does not seem to eat juice much. I will be getting rid of them soon enough.

now that i think of it the nexus one doesnt have kies air does it ? and it has the same android os issue?

Kies air shutdown wont help, did not even have it installed and still have android os bug

I've had both android os and wifi sharing eating battery, and I've never touched Kies. So it's not that.

not a soluton for me.. becuase i do occasionally use the wifi sharing so that i can tether over wifi.. the solution i am using which is kinda kludgy is to freeze the two wifi sharing apps with titanium backup (requires root).. works for me.. when i want to tether i will unfreeze them.. hopefully this will fix in a firmware update.

sorry guys I am late to the party.
WHAT AM I SUPPOSED to see for "Android OS" and "Android System"?
My phone right now is at 4 h 15 min (I charged it before going to bed, yes I sleep 4 hours a day). The phone did not do anything, but sounded Alarm to wake me up, and I had screen on for like 10 minutes total so far, plus the Alarm sounding and vibrating.
I have AOS at 37% up top, and AS at 3% on the bottom. This is not right?
I used Kies many times, but restarted the phone after the last time, and that was before the phone was charged last time.

my AOS is at 6% now - it was at 47% this morning... but i think that was because the screen was 0% whilst i was alseep, so yes your 37% is waaaay too high, mine was up at 15% but since i installed juice defender it has dropped to between 6-8%

Android OS / Android System percentages don't really matter that much - even if the device had a week long battery life, the percentages still have to add up to 100% - so something always has to be using battery.
The main problem seems to be the 'wifi sharing' and 'wifi sharing manager' services, which start up whenever you connect to wifi...

All these while will be only suspend, events/0 and android system. Both suspend and events/0 average on 35-40%.

You mean you're connected to Kies Air and wanted to play with your phone while waiting for files being transfer? The answer is yes, press the home button and do whatever you want, it will not be disconnected.

Sorry, I meant when I finished and exit the program, something continues to run in the background (wifi share?) that drains the battery?

Damn...
Android OS @ 46% followed by Display at 21%. Android system however, at just 4%. Yeah 46 is just way too high...

Oh.. my watchdog didn't report any app misbehave after I done with Kies Air.
My wifi sharing will keep on running on background at 3% regardless of whether I connected to Kies or not. Frozen it but it still there. LOL. Weird.

[Q] Rooting - effect on battery life

I'm trying to decide whether to root my NST or just leave it as is. I would certainly like to have the extra functionality, but not at a large cost to the battery life. After all, I did buy it as an e-reader first and foremost, so battery life is a very important factor.
I've searched the thread a bit and have seen some people complain a great deal about battery performance after rooting, however perhaps this is down to programs they decide to run, rather than the rooting process itself with the latest touchnooter.
So, could one of you veterans please comment on your experience with battery life after rooting?
Cheers,
R

From my experience, most battery is wasted when refreshing the screen. When you root, most of the time your goal is to use some random android app. This means you are going to be refreshing the screen often, which uses battery.
Someone else tell me if I am wrong, thanks

I don't think that root itself has any impact on battery life, but as you can do more with rooted nook, you consume more. Last week I've used mine almost 100% as a reader and battery is at 50%... and I read much more than 1 hour a day (that's the presumption for "2 months battery life" from B&N )

I've accidentally voted 'significant decrease' whereas in reality I have seen no change. An issue I've run into is that I have 'Keep Screen On' checked in EBookDroid so the page doesn't go away, but then when I'm done reading I forget to hit the power button to sleep it. This has drained the battery on me more than once.
Incidentally, it would be superfly if someone hacked together a script that copied the framebuffer to a file in the screensaver directory so when it went into sleep mode it would keep displaying the page while not wasting batteries.
I might hash that up when I have time.

Same thing was happening to mine. More of a cyan/teal, though.

we don't even need it to hook to the sleep event; i was considering just having a service that waits for two minutes of inactivity, clears out the screensaver directory (as mentioned) and then writes a screencap to it.

I've never tried it, actually...

I've seen something happen randomly, I addressed it in another post:
http://forum.xda-developers.com/showpost.php?p=24232518&postcount=9
On occasion the touch screen sensors do not turn off when the Nook goes to sleep.
Whether this indicates that nothing has gone to sleep or just that the sensor has not gone to sleep is unclear.
Still, you can lose about 4% of a charge per hour overnight.
If you run into this, there is something that you can try:
Code:
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
sqlite3 settings.db
sqlite> update system set value=0 where name='stay_on_while_plugged_in';
sqlite> .q
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
3 is the normal value, telling the Nook to stay on always with USB or charger power.
Unfortunately, once a charger/USB is plugged in it gets its state all confused.
Even with this set to 0 the screen sensors stay active while plugged in.

Or just turn it off

Thanks to all those who replied.
So, basically what you're saying is that if I were to root my NST, but continue to just use the nook software, I will basically get the exact same battery life? And that battery life is only affected by other programs that I may install?
So there is nothing installed standard on the nooter rooting software that causes additional battery drain?

Exact is impossible to say, unless you're doing some sort of structured testing. What I can tell you based on my experience is that, if you're careful with what runs in the background, you can see battery life on a rooted NST on par with what you'd see unrooted.
And that battery life is only affected by other programs that I may install?
Click to expand...

Only? No, not exactly. Whether you leave wifi on or off will make a big difference in battery life, whether rooted or not. Thus the statement that "battery life is only affected by other programs" is not true. Other programs may affect battery life, but may not be the sole consumer of battery.
In my ad-hoc testing, I saw battery drop roughly 1% per hour with wifi on. With wifi off, that drops to something less than 1% per 6 hours.

You're asking questions like a lawyer! I'm not comfortable saying that "there is nothing installed standard on the nooter rooting software", because the Android Market does check in the background for updates, so will consume some battery. Gmail is also installed, and can be set to do background updates.
You also haven't specified a rooting method. Some variants have loaded all sorts of additional software. I can only say that the software loaded by TouchNooter seems to have minimal impact.
Controlling when wifi is enabled has made the biggest impact on battery life in my experience. I'm using Tasker to control when wifi turns on and off, limiting it to a small handful of foreground apps. I disable any background synchronization I can.
The other question nobody can answer for you is how you'll use the device. Screen activity does impact battery life. If you're just reading, there's less of an impact than if you're playing Angry Birds.

SetCPU app
I heard that configuring the CPU may save battery life. I have installed the app SetCPU on my NOOK. Does anybody else have it? How could I configure it to save battery life?

There's a bit under the ManualNooter thread about underclocking to improve battery life. I haven't read about it myself, and have only read comments that the improvement is marginal.

Thanks Bobstro, appreciate your response. And anything you say can and will be used against you in a court of law. Nah, I'm not a lawyer....but an accountant...just as bad.
It sounds like the effect will be minimal after rooting the nook unless I install something more intensive.
That being said, can always just restore with the old backed up image if I'm not happy, so the downside seams minimal.

With the usual caveat that YMMV, and a warning to back up the device before you start (the NST can't always be completely restored as easily as other B&N devices), I think you're all set!
Just sign this release form...

Last report: mine... well I don't remember when was the last time I've charge it - but it was before Orthodox Easter festivities (i.e. 11 April), and is still at more than 60%, reading at least 2 hours a day!

i had a 4% drain overnight on standby. i don't have that many applications installed (nothing I can think of that would lead to high battery drain at least). i have to look into it but i seem to have "excessive" battery drain after rooting.

Is wifi on or off? Anything that wakes the device up will cause an increase.

I may have solved the famous battery problem on Nook & Nook Touch!

Hi,
I've been using Nook for two years and Nook Simple Touch for 5 months or so.
I've rooted both my devices and used them that way (until my original Nook got those screen problems and became unusable)
Starting from first days I realized that the battery life was quite shorter than advertised. In fact it was almost unacceptable, like draining %10-15 a day while standing by (at the regular screensaver)
First I thought this was caused by the rooting and custom firmware. I tried the regular disabling of services, but to no avail. After a while I decided to return to the stock 1.1 firmware (on NST). To my horror I saw that nothing changed. Then I rerooted the hardware, still same.
One day, while I was reading a book I got a call and had to leave the house very fast. Thus I bagged the NST and got out of the house.
After returning home, I left that bag in my living room and did not open it for five days. After five days I picked up the NST, which was %70 charged five days ago, sure that I had to charge it again. To my surprise I saw that the charge was still %62. How could this happen, I began to querry. And remembered that I did not manually activate the screensaver -which was my general behaviour.
After that day I did not manually activate the screensaver even once and the battery drain is never more than 1-2%/day.
I'm not an Android developer, I'm a regular computer guy (using computers for almost 30 years) but I have strong gut feeling that this may be the problem, that manually activating the screensaver is not same as activation after a time out.
I guess many people over here, being -not regular users but optimization obsessed technical people- prefer to activate the screensaver manually. Thus they have the drain problem.
If you are suffering the same problem, please test this and write your feedbacks over here. May be one of the coders can look into this problem in the end.
With kind regards

You may be onto something there.
I certainly believe that the problems are related to not fully going into sleep mode.
I have caught the Nook many times that it was supposed to be sleeping and the touch screen was still running.
I always used the power button when I'm done, I had the screen timeout set on one hour.
I just set my screen timeout to 10 seconds to play with this.
I couldn't get the Nook to act up with the power button shutdown.
To set your screen timeout to a arbitrary value (time in milliseconds):
Code:
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
sqlite3 settings.db
update system set value=10000 where name='screen_off_timeout';
.q
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db

foredog,
Could you clarify a bit, please?
Nook can go into screensaver via
timeout,
front button,
back power button or
"button savior Off" button.
Which button you referring too to manually activate the screensaver?

I use my Nook Simple Touch minimally and almost always use the back button to activate the screensaver. I see pretty good battery life upto 20+ days. The only thing I do differently from you is turn off wifi before I activate the screensaver. Maybe wifi is the main cause for the battery drain.

WiFi is definitely a big one.
Any easy way to "auto turn it off" with screensaver activation?

Don't know about that - I always use the "sleep" button to activate the "screensaver". Right now, I'm up to a month of use, and like 30% batt still. I turn wifi on when I need it, and off again when I don't. Glowlight on for like 20 min/day.
Actually really impressed with NST Glow.

Sorry I did not mention, that my wireless is always off.
@Apokrifx: I'm using the power button at the back to go to sleep mode.
What you all are saying is similar to general behavior. Everyone is not experiencing this drain among Nook users, only some.
In my case, letting NST time out really solved the problem.
What Renate says is really similar to my experience. Time and time I accidentally touched the screen (while it was on the screensaver and it asked for the swipe motion (meaning the touch interface is responding) which should not happen in the sleep mode.
I'll let you know if anything changes.
Thank you for the feedbacks.

I think the original post info is quite accurate. I notice when I don't go back to the home screen, and leave it on the stock reader when I put it down-- battery life is much better.
It appears that, when the stock reader is running, it shuts down most background services. But, that's just a theory.

i guess when u activate ur screensaver that wont drain power from ur battery ..... cuz in screensaver mood the animation on screen stopped like calculator screen ..... just display image and didnt move any pixels on screen ..... so .... ummm .... i guess ur problem may u not charge battery well .... let me tell u .... u must per month empty the battery until nook tells u that ur nook device cant power on .... and that will guarantee to u long life to ur battery also keep ur battery more efficiently and working perfect
hope i helped ..... best regards

Actually, I've had no battery problems in a while.
I've got rid of almost all the B&N stuff though.
USB host mode, with its polling seems to take a bunch of battery though.
It's still manageable.

I got my glowlight nook recently(after I stepped on my old Nook ST, ouch). When you have glowlight on and the Nook goes into sleep mode the glowlight turns off. It happens even if you press the back button. But... I had few instances when the screensaver activated and the glowlight didn't turn off... Can't reproduce this issue too often and with glowlight at least I know when it didn't turn off But other services might have simmilar issue.

I wonder whether this has anything to do with the wi-fi sleep mode you can tweak on normal Android phones... maybe the default sleep disconnects the wifi too, while the sleep button in the back just activates the screensaver.

The UK went crazy with the Nook last week and I got one. I also got the problem with the battery. I have tried this:
This is taken from qvc forum. I cannot paste the link, as this my first post. This is what Bogeygirl says: (you will need to google the text below, and find this on qvc)

I love my Nook Simple Touch that I purchased in February of this year. I was so disappointed that after this short time and charging to 100% it would drain to 8% over night..This happened twice. I did NOT have the wi-fi on and the automatic shutoff I had set to 2 minutes so no issue there. No recent updates had been done to cause an issue like this.
I was not worried because it was still under warranty and would be replaced. So I called B&N CS and went through all the steps with them to make sure it was in fact defective.
He asked me to totally shut it down and do a hard reset and re-re-register the unit. I was not hopeful that this would work at all. I know that a hard reset can fix a multitude of sins but I never would have thought it would work to fix this battery draining issue..To my surprise it worked.. Battery charge is holding just like before.. I read a lot and usually charge it once a month.. I am so glad that this worked. Such an easy fix but I will continue to monitor the battery charge just in case.

I have tried it, and it seems to work fine, holding charge OK. Bogeygirl says hard reset, but it is the soft one. Foredog says that you don’t need to click the power button to sleep (just leave Nook to do the job for you), but I do click it to sleep, and I do also tap the screen, just to make sure that it is properly sleeping. It is fine at the moment. I think the whole problem with the battery is a software error with sleeping mode, as you say here. I think you are right.
I don’t have it rooted, as I only want it for reading.
Do you have any other advice for the battery? Or easier? I think everybody is having problems with the battery.:crying:
Thanks

Deep Sleep Battery Saver?
Does Deep Sleep Battery Saver help with the power-button not sleeping properly?
It performs several functions:
1. Supposedly automatically puts the device into sleep mode whenever the screen turns off (if you configure it properly).
2. Functions as a task killer, with a whitelist, to clear out buggy apps.
3. The Whitelist allows you to prevent useful apps from being killed.
I still use the power button to put the NST to sleep. Last night it drained about 7% overnight, although I leave WiFi on and read RSS feeds for an hour before putting it down. Also, DSBS is configured to wake up the device every four hours.

The battery drain is due to some BN apps and Android System apps, mainly. I use the last version of "SystemApp Remover" for disabling apps (eg:AFfileDownloadService.apk,AccountAndSyncSettin gs.apk, BnAuthenticationService.apk, BnCloudRequestSvc.apk, DemoMode.apk, DeviceManager.apk, DeviceRegistrator.apk, Music.apk, NookCommunity.apk, Phone.apk, QuickStartActivity.apk, Shop.apk, Social.apk ,TelephonyProvider.apk, WaveformDownloader.apk).

I thought it was due to the device not sleeping after the power button was pressed?
I also removed those APKs from the system directory, thanks to many of you guys.

Switching Wifi Off Worked Well

WiFi is definitely a big one.
Any easy way to "auto turn it off" with screensaver activation?

I had a Kobo mini & was not happy with the formatting of PDFs, hence I *had* to get a Nook Simple Touch ... the PDF formatting is excellent. However, I soon suffered the battery problem & couldn't get it to charge. I followed the advice on this page and it works so much better now. This is what I did :-
1) Switch off the Wifi. I have no need for it anyway as everything I read is PDFs loaded via SD card.
2) To charge, make sure the device is fully off using the back power button.
3) I charge it using a wall socket, rather than a computer. I have heard that this makes a difference in charging times.
It's early days, regarding how long it stays charged, but I reckon I will be resorting to switching the power off, rather than putting it on standby. I'm just pleased I managed to get it to charge at all and I am back in business.

You probably don't want to resort to always powering off your Nook all the way, because the boot-up sequence uses about 3 or 4 times as much battery as regular use, making multiple reboots take up a large amount of battery.

To set your screen timeout to a arbitrary value (time in milliseconds):
Code:
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
sqlite3 settings.db
update system set value=10000 where name='screen_off_timeout';
.q
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db

Is there a way to change default values?

I have a nook simple touch glowlight, it's about 5 years old. Recently it has been saying battery too low to use. I plug it in and it goes to restart right away. When I look at battery life it my be at 89% (this was today). Is there something I can do to make this stop? It's quite a pain to to this everyday. I read on this a lot about a 1000 pages per week. In the "old" days a charge would last 20-30 days! Please help, I hate to get a new on, I love my nook!

Idle Battery Life / WiFi

Is anyone else having issues with overnight battery loss? I lost about 10% overnight in around 7 hours. I sideloaded BetterBatteryStats and I see that the WiFi is left running the entire time even if there are no running apps (and no email has been set up either). I know that on most (non-Kindle) devices there is a "wifi sleep while screen is off" setting but I don't see it on the HDX.
How is everyone else's battery life while the screen is off?

Same. There is no feature to turn off wifi automatically.

you can side load idle time connection manager which you can configure to turn off wifi after a set amount of inactive time.

Thanks! Works great. However i get 2 FC popups from gapps (which i have also sideloaded) whenever connecting to a network, suddenly they have become more annyoing. Hopefully someone will figure out how to fix those at some point

Ok on this HDX 8.9 battery life has been great. Was over 60% wifi off. Left it off or just over one day. I tried to turn it on but show'd one red bar on battery. Had to plug in and let it charge before I could use it. WOW this sucks.
No wifi nothing else left on and powered off not just simple click off.

I don't know why you guys are getting bad battery life while idle. I leave mine on for days and still have 90% three days later (after a full charge). Maybe it has to do with the fact that you have gapps on it?

Wakelock Detector reports that "Amazon Communication Services" has made a lot of partial wakelocks. I have no idea what this APK does. I have freezed it using TitaniumBackup.

It's killing my battery so I'm freezing it also. Anyone figure out what's it's for and what requires it?

If you are rooted and have installed android firewall and are using it in white list mode and did not allow all the Amazon services then some of them will repeatedly try to connect. This was causing my Kindle to be awake a lot until I renamed the apk in my rom slot. Not sure if this matches your situation but it helped mine. The service in question is inside Com.amazon.tcomm.apk.

Oh yes, that should help. Didn't think of renaming it. Will try that next if the freezing didn't work but so far it seems to be working.
