Hi,
I have a very recently purchased XDA II.
I was under the impression that the battery time was considerably improved.
Although I have turned down the backlight brightness when on battery power, it still starts to loose power when I receive or send a SMS for example.
Is this normal or do I have a duff battery ?
Steve
try turning off bluetooth when you dont use it
it's suppose to be a batt hog
Yup,
done that. I only have BT on when I am actually using my headset.
Any other idea's
Steve
when does it auto turn off ?
when does the backlight turn off ?
are there any SD cards connected seem to recall that they eat batt aswell
I've had mine a week, have the same power drain problem. After charging it all last night I managed to use it as a PDA for a total of 40 mins over a 6 hour period today before the battery drained. No phone calls were made, Bluetooth disconnected (I do have a 256 MB card installed, but I don't know if this has anything to do with it), furthermore the backlight is set to the default setting and the auto power off set to 1 min. In any case I would expect to get more than 40 mins use of the PDA, the specification states upto 15 hours.
I took the unit back to the store, they say that this is a rare problem (yeah right :roll: ), they gave me a new battery which I am now recharging, hopefully this will work.
mmmm, it's very strange.
I am doing a test now. I have a imate with the official imate upgrade. I have a gps sysonchip bt. One and half hours ago i connected the imate with the gps and i started a demo of 500 km. Now the battery is at 75%.....Maybe de last upgrade solved this problem.... :shock:
You should get far better performance than this.
Three things that can drain the power:
Communications/Peripherals - IR, bluetooth, SDIO wireless LAN etc. Disable all of them unless you're actually using them.
Processor hungry programs - check if you have anything running in the background that could prevent the device switching to full sleep mode.
Lack of radio signal - if you're out of contact with a base station, the device tries to connect at full power every 30s - a big battery drain, so if you know you're out of contact, turn off the radio.
However, even with everything running, I'd expect a running time way above 40mins, so it sounds like you have a hardware problem with your device. I easily get 3h full brightness, full processing (ie watching a movie or playing a game) with radio on.
Turn IR off?
Is there anyway to actually turn the IR off on the XDA II?
Just the Start-Settings-Connections-Beam-Receive all incoming beams checkbox.
tried the new battery today, same procedure as yesterday (no bluetooth etc), had a slightly better performance today from the new battery, managed to get roughly an hours actual use out of the PDA (games etc) over a period of... 10 hours, ooh atleast it lasted the working day so must be better... however still no way near the 15 hours PDA work time as stated on the box!
However something I have noticed is that every now and then (after switching off the unit and just leaving it on the desk) the screen comes to life displaying a running program, (just how do you turn off the media player? I now realise it isnt with the "X"). Anyway why does it "power" back up? I wonder if this has anything to do with my power problem, that perhaps it has switched back on whilst in my pocket (BTW I have set the buttons so that they do not switch the PDA on accidently)
So, I'm recharging again, (I think I might take the MMC card out see if tht makes a difference). I expect something better for my EUR 500, what is the point of being able to go online anywhere if you have to be plugged into the mains! If I can't get the damn thing to work satisfactoraily by next week then it is going back to the shop, despite it being a Gucci shiny piece of kit!
@MoistVelvet: Actually, it;s not so much the device itself but the operating systems that is the cause of a few quirks. Luckily, a lot has been written on this forum and other forums on websites such as www.ppcw.net. A lot can been improved by limiting the number of programs that can be found in the \windows\startup folder of the XDA II. I'd suggest you have a look around in the various topics. I ended up honing my XDA II to a point where I am actually very very satisfied with it's performance ...
Can someone repost the items in the windows start up folder than can be deleted and what they do on the XDA II.
I was surprised at the amount of apps in there, but dont know what I can safely delete.
Steve
Wiz,
thanks for the tip, I'll have a look around.
Well the batery did last longer yesterday, managed to get through a whole workig day before it ran out, so the jury is still out!
Realised perhaps one of the reasons why the unit would switch itself on, whilst at work I have a very low signal, so every minute or two the signal strength would go up and switch the screen on. I have set to auto switch off after 1 min, but I wonder if there is there a way to stop it from switching on?
Hm, my experience is quite different. I use it throughout the day with around 15 phone calls, at least 2 GPRS synchronisations, some other usage of contacts, calendar and email and when I get home it's still around 60 percent - the most drain appears to happen on the way back home when I use the BT headset...
When your uses so much more power you may like to check what kind of programs you use. First idea is to have a critical look at fancy today plugins... my worst experience was with Battery Pack, the best way to empty your battery :lol:
Maybe you like to use UpTime plugin (http://ae.inc.ru/uptime_t.html) which really tells you how much you actually use the PocketPC and which doesn't do anythings while it's switched off...

Actually, the reason it periodically switches on is the O2 Homezone application. Whenever your phone changes to a new base station (which can happen even if you don't move), the stupid Homezone app turns the phone on. This is a known issue, and the only known remedy is to disable the app completely (remove from Autostart folder, soft reset phone).

Hi
I have an xdaII, which i load loads and loads of things onto. I did find that the battery was draining quite quickly. eg. charge it all night, just leaving it running in the day with hardly any use would drain the battery by about 90 percent! Bluetooth was off etc.
One time, the thing drained completely, and it needed a hardboot. Im going to send it back shortly for investigation/repairs.
However, since it hardbooted, i have not installed a thing. And i am finding that the battery is lasting a lot longer. I managed to go 3 days, of average usage, (few incoming/outgoing calls), without charging the battery!
This makes me think some apps must cause the battery to drain. I had battery app installed (that runs in today screen). I had fonix voicedial installed. I had quite a few games installed.
I think some software was causing the battery consumption,.. possibly battery pack.
re
I have previously had problems with battery drain, due to apps running in the background.
I also found specific apps like the battery pack, LAN sdio, bluetooth and the camera app, would drain the battery quickly.
Although you can manage closing apps down through settings/system/memory/running programmes I found the app Gigatask http://gigatask.com/ a simpler way to manage tasks.
There are others, but I found this suitable for my needs.
Now when I close an app I know it's closed and not running in the background draining the battery.
I still charge daily, habit now when I get home from work, but I have no worries about battery drain, and it rarely goes lower than 65% for a normal days use.
Cheers, Shire
turning infrared beam recieve off will help a little
:wink:
my exec battery doesnt last very long.if i fully charge it then turn the phone off,the battery is dead flat within 24 hours.and thats when i dont use it at all.
the only way i have of charging it is with a USB cable.
is there something i,m doing wrong?
try turning on flight safe mode when not in use that tends to save a lot of battery life
I left my Universal in the closed position at 47% and two days later returned to use it. It still had 45% battery life. This is with bluetooth turned on (I never have it turned off).
I hear WiFi is quite a battery drainer, make sure you have that turned off. I don't use WiFi (Only GPRS) so I never have WiFi on.
Hi DavidT. may i ask what ROM you're using now. my phone only last for about 6 hrs max. without any use. NO BT or wifi on. thanks.

I'm using O2's 1.30.107 WWE ROM.
I decided to test again last night. Left it at 89% in the closed position approx 10:30 pm, opened her up this evening at 7 pm 87%.
If I constantly use it, I only get about 6-7 hrs of combined phone/gprs/pda usage out of it on the regular battery. On the extended battery I can use it for a few days
make sure that there are no background programs running. It should run for almost 3 days without use in that mode. If you let some IM running that it won't last for more than 24 hours
ok, there are a lot of forums on this topic, and a lot has been identified.
I am at the moment using Ivans AKU 3.2 Rom, and this is a great battery saver. Not sure the tweaks used, but here are some additional suggestions:
1. Turn screen off after 2 minutes
2. Turn device off after 3 minutes
3. WIFI auto off after 2 minutes
4. Disable bluetooth when not in use
5. Turn off beam auto receive
6. Turn off error reporting
7. Remove anti virus
8. If you dont use UMTS, disable and switch it to always GSM
9. Ensure active sync isnt constantly running
10. Use GPRS only when you have to
11. Wind back the screen brightness on batteries to the very minimum, just before it blacks out.
12. Try to minimise the number of SD card read and writes (ie today screens, memory card readers, icons linked to SD card)
With all of this, and only general phone, PDA, and WIFI usage occuring sometimes during the day, I could get upto 3 days on Ivans rom. But usually, on the imate rom about 1.5 days.
If I use all of these non-stop constantly all day, it will be pretty drained after 1 full day.
It has occured in the past, and I dont know how or why, but something was running, and within an hour or two, battery was completely gone.
I couldnt fix it, so I hard reset and it didnt happen again. I suspect some programs get themselves into an endless loop (eg Activesync or others), and perhaps reading memory cards, etc caused it dont reall know.

http://blogs.msdn.com/windowsmobile/archive/2006/08/04/689069.aspx
I am unable on ivans to kill it fully, always comes back.
on older roms, try
1. open activesync
2. add server source
3. enter any dummy entries
4. set schedule to manual
5. delete server source
6. reset
if u use push email, this won't work.
My battery on the HTC Pure went from 45% charge to 2% auto-shutoff within a matter of 1.5 hours without any usage on my part. In fact, I had rebooted it and not touched it since.
The thing has been dying a lot faster after I installed some programs from Marketplace. I'm wondering if they are doing background processes that zap its power or what.
Any recommendations on monitoring what's going on in the background???
try to calibrate battery
(thanks helgee):
1. Discharge the device. Absolutely.
2. Take out battery for 60 sec.
3. Put the battery back. Don't switch on the device!
4. Charge the device by normal way (not by usb!) to the full state (green LED).
5. Take out battery again for 60 sec.
6. Put the battery back.
7. Switch on the device.
How can you discharged your battery? I didn't find a option on my Touch Diamond 2.

Exactly the same thing here, after installing some apps from Marketplace, the batt started to drain very fast. Don't know why yet. The apps installed are:
Mobeedo
Bing
Pocketnow
The Daily News
I've removed Mobeedo, The Daily News and Pocketnow just to test if they were doing something.

Fast battery discharge
I had this very same problem. I had it with WM 6.1 and the Pure. Both due to the same app. BING is your problem. If you have a memory card in your phone it causes it to be constantly accessed instead of just on demand such as with storing pictures from camera. This is a battery life killer. Ditch BING, remove your storage card, save what you want to a PC and wipe it. After that put your saved files back on the card and put back in phone. This should stop the battery drain issue. Hope this helps.
ALSO: Some people swear by the battery drain and charge thing...others do not. Use it if you like but without getting rid of BING or finding a way to keep it from accessing your memory card the difference you will see will be barely noticeable.

u can change the radio , then u will get better.

Hello everybody. I need a help with next situation.
I bought my nook like month ago and rooted it with TouchNooter after a couple of days. Everything worked fine for me - coolreader + goldendict, wi-fi, everything. One thing that did not satisfy me was energy drain, so i tried to install another ROM with "minimalistic" package on board. Before i switched i did factory reset and factory restore - my nook has 1.1.0 stock version on board. Unfortunately i discovered that "minimalistic" ROM does not contain android market - so i would not be able to install GoldenDict properly (because programme askes for license check). So i decided to revert back to TouchNooter (with factory reset and restore ofc).
Since then my nook keeps freezing all the time - whatever i do - its just freezes.
If Im trying to read a book with both default reader/coolreader - its freezes after couple of pages. If Im trying to press settings - its freezes again. And it wont boot up without power supply - i need to plug my nook via usb to my PC or to jack.
With energy supply it works fine without any random freezes, reboots etc.
I made a conclusion that its not about ROM (i tried like 30 times factory reset/restore. I tried both versions of n2T Recovery. I tried to use Touch-Formatter.) My device keeps freezing even totally unrooted -i have to plug my device into PC in order to complete registraion process - otherwise it will freeze before my attempt to connect. My nook cant work on its own - it should be plugged in into power source.
So i tried to charge my nook more than it requires - i left it charging for a day with jack. after i unplugged it battery stats shown me 100%. I started to read. Notably that i spend half day reading and using goldendict without any problems, but when my battery drained to 93% my nook started to freezing again.
I just dont understand what is the problem. Why does my nook work fine with cable and cant live without it? One thing i did not do yet is to disassemble my nook and trying to unplug/plug battery - i dont know how it can help but i dont have any options left...
I hope you guys can help me coz i've tried to find same problem and haven't succeeded. Thank you!
Most battery systems require calibration. To do this you need to charge it to full, drain it to low power.. around 10%. 3-4 times is the usual number needed. It sounds like you are having some sort of battery problem and calibration may make the meter read properly. Otherwise it might be time to try for a warranty replacement.
Every time you change roms you need to allow for the calibration period again.
I doubt that the battery calibration is that far out, but you can try:
Code:
am start -n com.android.settings/.BatteryInfo
That will give you all the numbers on your battery.
Voltage goes from a high of 4.200 to about 3.800 as dead.

Thank you Renate, but how do i perfrom this and what should i do with all this numbers?
To Nova - i cant charge/recharge my battery several times in order to re-calibrate it - because as i said it simply freezes once been plugged off
That was a command you type in a shell on the Nook, normally over ADB.
You do have ADB working?
It sounds like your battery has simply had an early failure.
I'd try restoring it to stock and returning it under warranty.

I'm also experiencing freezes with my NST (rooted 1.1.2). It has 1 1/2 year with light use (approx 30 mins per day).
Whenever the battery reaches 95-80% my nook would start to freeze.
I've tried using "Battery Calibration" app to restart the battery counter but it didn't help.
I know it's a battery related problem but I wouldn't say it's a hardware problem because it doesn't show the "too low to power on" message. Show I unroot my Nook?
Any suggestions?
Did you try looking at your battery info - as Renate shows in post #3
in adb shell :
am start -n com.android.settings/.BatteryInfo
Voltage goes from a high of 4.200 to about 3.800 as dead.
I'm checking with Battery Calibration app. It now shows 96% and 4033mV
I'll recheck it on the next freeze.

Well, clearly that's wrong as 4.0 volts is not 96%
Can you charge the thing to around 4.200 volts?
Run the battery calibrator reset only when it's at 100% (or so they say).
Does the battery health indicator say good?
Yes, the battery health reads good. I reset the battery calibrator when the actual led light turned to green (my nook was showing 100% a lot before that).
Today the battery was showing 93% and 4014mV.
I maybe onto something. I experienced something weird. I kept reading using the official nook app and checking from time to time the battery app. It was always somewhere 92-93% and 4014-4012mV. Seconds after I highlighted a word the nook froze. I rebooted and immediately I read the battery app. I read 92% 3895mV. I waited a moment and then it went back up to 4010mV.
It seems there something going on on CPU intensive tasks. I wonder if the battery is acting weird or there is some task that misreads the battery status ands freezes the device.
What do you think?

I've found this suggestion in Mobileread forum
http://www.mobileread.com/forums/showpost.php?p=2186779&postcount=103
I opened my nook, disconnected the battery and put all things back. So far it seems the freezes are gone. I'll report any problems!
I've doing this for a couple of months now (once every 2), no freezes anymore.
Perhaps the NST power handling firmware has a bug? Been seeing this issue fixed by that on several forums.
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.

Hi,
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!
