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.

how can I kill the ActiveSync process?
Take a look here for tips and a great write-up on power usage...
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.
I was just wondering what is the average time of battery life on your wing..mines is currently about 10 hours idle but while im using it that goes down to about 5 or 4 i just wanted to know what is the average before i call t-mobile and ask for a new battery.
A few of us here have been having problems with the battery actually. When I first got the phone, I left it clean and stock. I would do a lot of texting, make a couple phone calls, and play a few games here and there. From 7am to 1am, I would go from 100% to about 54% (18 hours of usage). Now, if I leave my phone idle for 2 hours, my battery drops down from 100% to 80%... I can't even go a full day without needing to charge the darn thing. 200 hour idle time my arse!
But personally, I don't think it's a problem with the battery... The phone is doing something in the background which is causing a massive battery drain. Right now, I'm testing my phone to see if I still suffer the same drain while in flight mode. I'll post the results HERE in about an hour from now.
The longest the battery can last is 1 week...
On a full charge, you can talk for 5 hours...
the more features you use, the more power it'll consume.. if you do a lot of internet browsing, I believe I saw GPRS Data connections use more power then WiFi.. so use wifi when available ...
also, be sure to regularly check your phone's task manager before setting it aside for long periods of time... sometimes it can be hard to notice the camera, text/mms, calender, Internet Explorer, Windows Media Player, are all running in the background while you're at the home screen...
My wing usually lasts me from unplug at 8am until plugin at midnight... power usage always varies a lot as... as you can tell.. the data connections use a lot of power... and if wifi isn't available, it uses at least 30% more power doing a GPRS Transfer -- based on the initial information i've read about the issue.

I noticed Bluetooth and WiFi taking more battery than GPRS
As long as I plug it in while I am at work to a USB cable, I don't seem to have any battery problems. I use GPRS and SMS constantly.
I spend the whole day on the phone ... between texting and I receive all my work email directly to my phone... so I'm on it various times during the hour... and it seems the battery drain is huge.
all I have done is turn the screen brightness down whenever I'm not using it, and have the dynamic overclocking on, so the processor goes down whenever its not in use ... but I still think the battery drain on the wing is ridiculous.
Well david, overclocking doesnt help
Im clocked at 247mhz, i can make it last about 24 hours using it here and there. calls about once a hour for 5 min or less, texting through the day, and occasional wifi use. at stock clock speeds, it lasted about a day and a half, but it all depends how much you use it
At 1st i thought the battery darin was rediculous as well but when u think about it when u use it the battery goes down about 8 times as fast( depensing on what ur actually doing w/ it.
Now i charge it at night and go to school with fully loaded battery 6AM, i text all the time and when i get home its around 85% 2:30PM, use it occasionally and at the end of the day after at least 3 hours of talk time its on around 30-20% i could last w/o charging it but i charge it overnight to full, with NORMAL use and not talking for about 4 hours per day so far its lasted 4 days for me. could have made it to 6 but i wanted to showoof my new phone to my friend
so battery life is not that bad just depends how much u use it, Also if ur listening to music just turn off the screen and thats a REAL battery saver. also press the power button when on the phone and etc.
Wing Battery Drain
I have improved my Wing battery drain by doing the following...
- Turn off the automatic weather update on the Today Plug-in
- Check my emails manually (do send receive when I am ready to read)
- Suspend device when not in use - need to use device lock app.
- Update ROM to PDA Viet v 14 (thanks to easy instructions from David)
With the new ROM and the device locked - even the accidental press of any of the face buttons (when phone is in pocket) turns the device back on - even though the screen remains locked (due the Device lock app). Is there any way to suspend the device completely so can only be turned on by hitting the power button only? I would still want to receive / answer calls etc. without having to hit the power button....
Go to settings, Lock ... and there is an option to lock all buttons except the power button when device is powered down.
I am trying to fix my sisters Wing (I have a Wizard). I have tried disabling background programs, as well as setting things to be more gentle on power usage, and still she loses battery like crazy. I know the Wizard had some battery drain issues with certain WM6 cooked roms, and a cab fix helped. Does anyone have a cab fix for the Wing? Also, reading in this forum section, it seems that the Wing doesn't always disable background programs. Would you suggest a third party task manager to "pick up the slack" or does it not matter, due to the nature of the winged beast?
I appreciate any suggestions. While I am new to the Herald, I am "old hat" on the Wizard, so I do have a general understanding of how the HTC devices work.
Thank you in advance.
I have read a lot of bad stuff about battery life with every rom except the OME t-mo. I had the PDA viet and battery life was terrible, With the stock rom it is at least 4x longer.
hello ive the same problem with the last 4 wings ive and ever since ive switch from the stock Tmo OS and upgraded to the TouchFlo OS, Ive noticed a huge differnce with the battery life even overclocked
If your will to taking the risk ide say go for it, i jus started messing around with rom and i got say its a big improvment from the original wing which i was ready to throw against a wall!!
I have Touch Flo on my Wing, and if I charge it to capacity I usually only need to do so it every other day so long as I don't play any NES games on it. I keep the wifi off if I'm not using it of course. I have it dynamically stepping the CPU in a range from 100mhz to 234mhz. It really seems to help extend the battery for me, while still giving it the tiny extra kick it needs to run nes and sms games.
My wife has the official wm6 rom on hers, but is also dynamically overclocked as mine is. She needs to charge hers nightly, BUT she also plays solitaire and bubble breaker daily.
Overall it's on par for battery life with my prior motorola phone, which I never used for anything but regular phone calls. With that in mind I'm not necessarily impressed, but am definitely content with it.
I've had HORRIBLE battery life and AWESOME battery life, all within the same week. lol
There was a problem I had at one time, where filesys.exe would take over all the CPU and kill my battery.
Here's what I do, though.
Dynamic overclocking/underclocking
Turn off GPRS when not in use
Disable Push Mail
Turn off WIFI and Bluetooth
Turn the screen brightness down
Turn off the screen altogether, even when on a call, unless you need to see what's on it
There's a few tweaks out there that deal with enabling the power saving features on L2TP and stuff...
First post here-
I've had my wing about a week now and have a question concerning battery usage.
It has always been my understanding that batteries will develop a "memory" if you charge and recharge them under their full charge capacity.
i.e. if you use it down to 60% and then charge it to 100% it will remember that and not use the full original 100% charge. obviously over time not just from a single "half charge" like that.
So since every time you connect it to USB to sync it begins the charging process, won't that wear down the battery and make it develop such a memory?
Is their anyway to connect to to the PC without having it charge?
I have always preferred to have any mobile device drain it's battery to nearly empty before recharging to try and minimize the memory effect.
Thanks

Today's lithium ion batteries do not develop this like older rechargable batteries. You can plug your phone in at any time without worrying about losing battery capacity!
Thank chris30_2001, good to know.

I listen to Streaming Radio with my Wing at work all day. I get approximately 4 hours of listening time before I have to swap out with another fully charged battery.
I use PBar to shut off the screen while listening.
I'm running the touch rom without the actual touch. I can't remember which one it is. I spend at least an hour a day gaming (text twist, random solitaires) on it. I usually hit up the web a few times a day for 10 minutes a shot. I use it as an ebook reader. I send txts constantly. I talk about half an hour a day. All this leaves me with about 30% - 50% of my battery by day's end. Now, if I turn on bluetooth all day it will end up around 18%. Wifi is such an evil power hog I never turn it on, EDGE is fast enough for me. I charge my every night under my pillow (it's my alarm too). Battery life has been the same since I got it about 6 months ago.
Edited to add: I also do some dynamic underclocking for things that don't need a huge amount of power, like my budget program, etc.
Hi guys,
I have a problem with my Jade. I've charged it last evening and I've barely used it. When I've went to bed it was 96% charged (ARIELbattery) and 10 minutes used.
This morning, when I've woke up, The battery was 33% and and the phone was 34 minutes usage time.
Something is wrong. Since there were no bluetooth, no wifi, no anything activated. And for sure, nobody played with the phone during the night.
This is not the first time when I see this behavior, but is the first time when the decrease is so big.
I suspect an app, but I do not know which of them. How can I see it?
Do you have other suggestions?
thanks!
There are some possible reasons:
Some SD-Cards seem to drain battery, so you can take it out for a test.
Some additional software is told to drain battery. Did you install something?
It is also helpful to switch to "flight-mode" over night. This normally reduces battery drain to nearly zero, if no additional consumers exist.
Hi,
Yes I've installed some software, like gAlarm, S2U2, icontact,ThumbCal, Skype, etc but last night none of them was started.
What can I do with the SD Card?! I need the SD-Card. Which card does not drain battery and which does?
I cannot turn off the phone over night.
Some clues here in this forum

I've read those before posting, but there was no answer to my problem. I have 67% drop of battery in 8 hours without touching the phone.
This is most likely that your device goes to screenoff or unattended power state instead of sleep. Your power settings might be corrupted. To change that go to your power settings advanced tab and change everything there (checkboxes and sliders), press ok and then change them back as they were, press ok. I'd suggest to keep the device turning off in one minute while on battery and none of the checkboxes for cord powered mode. There is a really freaky thing that even if you get your device to sleep with power button it will go back to screenoff mode after time specified by the turn off device slider while on battery IF you don't have that turn-off-while-on-battery checkbox checked there.

Thanks for the answer. But I do not really understand what you are saying here.
My power settings are: 30sec for Screen Light and 1 min for Device (on battery).
None of the check boxes is set for the case when the device is powered.
It could also be due to the battery defect. After some time the battery could lose its storage ability (because of the defect), despite the mAH stated.
As a comparison, my battery is nearly one year old. On full charge, overnight drawdown (on sleep mode) is about 2%-3% .

I have no own experiences with this programs but Skype for example needs permanent connection to internet when activated (be care of the background job!). This uses data connection and this drains battery. I can not quantify this in %. In addition Skype does not allow the system to switch to deep sleep because it needs permanent connection!
None of the app was started. I just have Skype installed, but it was not used.

I found some German threads that discuss a problem with this software and battery life. Some loose 10% over night others 50%. I think you should try to uninstall (and afterwards soft-reset!) for a night and see what happens.
Please keep us informed.
First of all, I've disabled the 3G. Now it only gsm with gprs. Since I've done this it seems the battery drop is ... super ok. If yesterday morning I've had 33%, this morning I've had 20%, so 13% drop in 24h, and the phone was used normally as before.
last night the S2U2 was not started.
I will wait until the battery level reaches 10% an I will do a full charge.
I will keep you informed. Thanks to all for advices!

Hi,
So now, 2 weeks later... after setting my Jade to GSM only (no 3G) I get 7-8 days of normal usage. As I said, before I always had to charge it the third day.
Normally, i get -28mAh drain in standby. When the screen is on around -130mAh (for wake up) and then -70mAh. In a gsm call i get around -250mAh.
I did not switch the phone back to 3G yet, but I will and I will see again the battery drain.
PS: the values were provided by Mobadi.
i believe i have S2U2 installed... and my phones fine!
i have the overloaded rom... and battery life seems great only needs charging every 3 or so days and i do use it quite alot!
so...
after some time of testing and re-testing I still have, from time to time, the behavior that during night I see a massive drop in battery level and an increase of the usage time.
I do not know what is going on, but I suspect that some app is waking up the device to do some work (without turning on the screen), and the Jade cannot go to sleep anymore for a while.
I've notice the same behavior on a HTC Diamond 2.
Since none of the app I have installed on my Jade are installed on my friends Diamond2, I have no idea what app could do that.
If anybody has any idea, feel free .... I am idea-less!
I've made myself a little application to log the current values of the power data. So, I've saw that my phone wakes up each hour by himself, without turning on the screen, does some work (cca -70mA) and after 30sec goes back to sleep.
Any ideea about this?
Can someone explain to me how, with the phone turned off (just the phone option in settings, almost airplane mode, but still using WiFi) and screen brightness set to lowest possible,
am I getting a 21% battery drain in 1 hour????? I just fully recharged this joker, and within 8 minutes it went to 99%, soft resetted, 95% at startup...soft resetted again, 90% at startup...within 15 minutes I had dropped 10%!!!
2 nights ago, I left the phone on standby at 65% overnight...woke up to a 2% battery charge!
I looked at task manager and there was nothing running...okay, just typing this and down to 77....I'll soft reset and update the %.....11:05pm...
okay...it's 11:07 and upon startup, phone batt. % was at 70%...I lost 7% just by restarting...
currently using Xannytech 1.7c ROM (yes, I need to change my sig...)
Any ideas?
i am no tech guy but i'll go with saying maybe your battery is dying or i donno have you tried getting a new one ? my battery reading is highly consistent and they sure as hell dont fall down as much as yours does in short time periods. mine after a full discharge charge cycle holds on every percentage like a m o and stays with me for two days.
performed a hard reset?
SR will only really fix lockups/unresponsiveness (like the reset button on your PC)
HR is effectively a full reinstall from scratch. will (or should) cure power management issues like you seem to be having.
ofcource, it could be the battery. A HR is free so i'd start there...
I treated my phone like a baby for its first three months, and the first day I left it unattended when I went to the loo, my friend spilled water all over it...
Now the (range of new) batteries I buy for it last only 7 hours tops before hitting 0%. So maybe, like mine, there's something in your phone that is rapidly draining your battery? (Still not been able to solve my problem six months down the line )
Morning...left the phone off overnight and woke up at 69%... Never spilled anything on it...maybe flashing to stock rom may help?Just reading your posts and I'm down to 67%. WITH PHONE TURNED OFF AND LIGHTING AT MINIMUM. Maybe flashing to stock may help? 66%
11 am...well, ended trying out a reflash of Xanny 1.7c...restores ALL programs through Sashimi. Went to do some grocery shopping (yes ladies, I cook too!), had phone on, playing music through headphones for about an hour and battery went down 5%...an improvement...will update if anything else changes

My phone got moist when I was running in the rain, and the power button (on the top of the phone) seems to be permanently pushed in. It looks ok and I can push it, but the phone doesn't notice. The result is that my phone is constantly draining the battery and I can only get about 4 hours out of a full charge.
Also note that some ROMs are configured to download data for multiple reasons/applications, at regular intervals. These include:
- weather updates
- My Location updates
- Twitter feeds
- email checks
- AGPS updates
- GPS updates
- updating phone's clock from Internet
- MyPhone synchronisation
- PIM Backup scheduled backups
Then there are numerous settings that may be set to run all the time:
- Infrared ("Beam" settings)
- Wifi, especially Wifi power mode (Performance vs. Best Battery)
- wifi router
- Bluetooth
- Vibrate (any time the phone vibrates, a small electric motor spins)
- enabling auto-dimming features such as auto screen brightness control
- Smart features that use the phone's light or 'motion' sensor e.g. Mute ring when phone placed face down or make phone ring louder if placed in your pocket
And there are settings that have a more pronounced impact on battery:
- wifi in a weak signal environment (more power is used to boost signal)
- wifi encryption type (none vs. WEP vs. WPA) (WPA uses more CPU than none)
- screen brightness
- volume
- screen dimming and blanking timeouts
I'm sure there's more, but these are ones off the top of my head. Some ROMs have some of these features enabled, some features are enabled by you when initially configuring after a flash. If you want to keep power consumption low, you need to check or consider all of these and make decisions that trade functionality for battery life.
And of course, your battery could simply be poor, wearing out, faulty, or low quality.
