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:
So do you leave your Bluetooth always ON? I have it off, then switch it on when required. But would be curious to know what the battery life is like if I leave it always on.
Thanks.
mine is always on, battery life is around one day or a day and a bit more
but every time i'm home its on the cradle so dont really need to worry about battery life.
I read on a forum somewhere, could even be this one that a bloke left his Jam on standby until the battery was dead. First run with Bluetooth off and second one with Bluetooth on. The Jam lasted 2 days with the screen left on, but no processes running at all. He didn't pick it up once and there was no sim card in it.
With bluetooth off he gained 6 minutes of battery life!
I can't guarantee the truthfulness of this story, but it's what I heard.
I've read a few posts on HTC Wizard battery life and I'm trying to quantify what I'm seeing (which is hard given varying conditions under which the device can be used and what features are active but I'll attempt that here). I'd really like to hear what other pepole are experiencing under similar conditoins.
I’m getting about two days worth of battery life before the unit is warning that the device needs to be recharged. Here’s what I’ve done with it over the past 2 days:
· 47 minutes time spent using the phone. I get the full 4 signal bars just about everywhere I go, including and the office and at home. I have not used the speakerphone at all.
· About 1 hour of PDA use
· Bluetooth and WiFi have been off. There was no GPRS use during this time.
· The screen brightness is set to the lowest level possible, one setting above the backlight being completely off.
· When on battery power, the backlight automatically shuts itself off after 30 seconds and the device turns itself off completely after one minute.
· I’m running Windows Mobile 5.0
The battery currently reads 18% after 2 days.
Is this in line with what other people are seeing?
I used to drain my wizard to about 50-60% in one day (from morning to evening), when I still let it go to standby, so that seems about right. It goes down a bit faster now because I always leave it on (just let the backlight go off of course) so agile messenger will stay online...
I'm pretty sure this battery life is pretty good for a pda phone though, you can't compare this to a regular phone.
I always connect it to the charger at night so it's no problem for me, and I bring a very small usb cable (like 15 cm) when I don't sleep at home. Usually there's an opportunity to connect the wizard to a computer somewhere so it'll charge, the computer doesn't need to recognize the wizard for that.
I need to charge my Wizard evry night, if it's friday with party etc alot of calls i need to have my samsung d600 with me becuase the qtek goes empty around 23.oo :/
Just done a typical "intensive" day, and I'm really pleased of that thing. Here's what I've done:
~50 min on the phone
~2h30 MP3 playing with TCPMP, LCD off of course
~30min e-mail and internet through wireless
obviously a bit more PDA use, cause uptime meter says 4h39 :wink:
I still have 54% battery at the moment.
Useful to mention, forgot to turn off wireless after browsing, so it stayed on for like 1hr with device off, and that still drains juice.
Backlight is set at the middle.
Once again, my BA would be dead by now. I had ~4h PDA use at standard clock settings, 2hr with wireless on. The Wizard just doubles both these figures. I definitely understand why they've dropped that guzzling XScale... wish there could be an optimised version of TCPMP soon though, video playback is the only thing where i see a real difference in speed, haven't managed to have a video playing smooth without hangups yet.
Skype doesn't run well, but it didn't either with the BA without overclocking it at the maximum it would hold, giving a stunning 1h30 battery life (with wireless on obviously). The device was really hot while doing this, and the standard charger would not give enough current even to power the device, battery was still going down when connected. Had to use a 2A Axim adapter to charge while skyping :shock:
So definitively a GREAT improvement.
I used my MDA Vario the other day and it went down to 18% in approx 4 1/2 hours.
Screen was at max brightness and on for the whole time,
Tom Tom running.
Bluetooth on
About what I'd expect. I don't think my Treo 650 would be much better in similar circumstances.
I just updated the other thread about the battery that up till now its been fine but two days ago the dreaded issue started with me too
I've just lost 20% in 3 hours without doing anything (its been off since)
AKU2 rom gives a definite improvement, I can have 85% left after a day of normal use.

Which AKU2 rom. T mobile hasn't released one for my phone yet, to my knowledge.
The qtek rom, many vario users are using this rom out of frustration for t-mobile not releasing theirs.

Hey if you upgrade the ROM you should run some tests before installing any applications. It would be a definite advantage to make sure it's not some buggy app that's causing your battery drain.
agreed... I think that is my issue too that it could be a memory leak somewhere in one of the programs
can only put it down to registrywizard, uptime, or resco, the latter i doubt very much though
I upgraded my vario to the newest imate rom and would totally recommend doing so.. my battery life is about double what it used to be now (may have installed something dodgy that was draining it though)
Its also much faster in operation and seems to be a lot more stable too (I suffered a lot from the random reboot problem previously)
what did you upgrade from?
and what rom version are you running? the ones on the ftp for kjam are numbered a bit strange and can be confusing
The numbers are confusing for me as a noob to WM5/wizard.
What is the difference between the Qtek & the Imate roms?

WiFi doesn't drain battery when the device is turned off, cause the WiFi module will also be turned off automatically - just test it: leave WiFi on and press the power button - after a few hours look at the effect on the battery... :wink:
I usually recharge my Vario every 3-4 days. Although I don't use WiFi and I also don't make many long calls I usually use GPRS always on to receive my mails. I also use BT quite often to listen to music over my A2DP headset - maybe one hour per day on average...
So there must be something wrong with the devices of some of the people posting here... :!:
Hi,
I have a HTC HD2 and I was wondering why the Battery loses more than 25% over night. (100%) eight hours before.
Now I try some settings and I noticed that the cause is the bluetooth device.
It doesn't matter if it is visible or not. If it is turned on the device lost more than 25% energy within 8 hours.
If I turn bluetooth off, then it loses 5% within 8 hours which is ok for me. The 390h Standby has been measured with a clock which runs at least 5 times faster than normal clocks. Or the phone was turned off or without a SIM Card (and bluetooth was not active )
Does anybody noticed the same problems?
I have a Touch HD and a Touch Diamond 2 and both don't need so much energy and bluetooth is always on and discoverable.
Please don't try to get to far away from the topic in this discussion
I've noticed that seems to be contagious like a disease and at the end we talk about the greenhouse effect because I am to lazy to turn my bluetooth off when I don't need it...
Thank you for helping
And... Yes I've used the searchengine but with no satisfied results
Battery drain..
Actually my battery won't last a day!
During week i'm receiving a lot of mail (100+) on 4 accounts (exchanges server, hotmail and 2 accounts using imap) so I figured is was the mail..
but this weekend still noticed the battery drained very fast, and yes, my bluetooth is constantly enabled. I hate disableing it as I need it to automatically connect to my carkit.. but i'm gonna give it a shot.
Well... I am not alone with this problem.
But is that a problem with a driver or a hardware problem?
Maybe it could be fixed?!
Is there a way to NOT drain the battery and have a BT headset enabled all day?
I too am curious to know if having a BT headset always on, as the case for me with my HTC X-7501 as I need to answer calls while driving about.
My X-7501 will never last all day because (I am sure other factors pare at play) the BT is always on. Turn it off and the battery drain is lessened noticeably.
My concern is it will be the same with the HD2 (my future phone.
If anyone can shed some light on how to deal with this when one needs BT on most all the time, it would be greatly appreciated.
I cannot imagine trying to enable BT whenever a call comes in and doing so in time to answer the call.
Anyone have anything to suggest?
Thanks,
Claude H.
Yes. My HD2 with 1.66 rom, activating Bluetooth, to connect to BTheadset when needed, will deplete 30% within 7hrs....overnite with no other activity... *sad

Hi, is it possible for anyone of you with this problem to export registry? I would like to setup my phone to be discoverable even when phone is in standby. Apparently this is the situation with your phone and having a registry would definately help me.. thanks
Hi guys, please bear with us on this one.
This is my 2nd Android phone, I used to have an Hero about 6 months ago. i really liked the front end but the screen was small so I upgraded to an HD2 which I still have. On the HD2 the screen is huge but Win Mobile lets it down a bit. The marketplace is expensive and very limited and the amount of apps for Win Mobile seem to be getting less and less, especially supproting the 800x480 WVGA screen on the HD2.
Anyway I was due an upgrade and Orange offered me the X10 for £20 which i couldn't refuse. I am trying to like the phone but the biggest issue for me is the battery. I did the usual of leaving it plugged in for 16 hours as recommended by orange etc. If the phone is on standby I seem to get around 8 hours and the battery will be down to about 40% remaining charge. That is on standby with the top button pressed and the phone on a black screen. This is really poor considering the HD2 can run almost 2 days on standby before loosing 60% of its charge.
Anybody got any suggestions on how to improve this? Would it be wise for me to do the debrand as mentioned in other threads? It is currently on build R1FA014.
Thanks for the help.
The battery will improve in time, after a few weeks of use the X10 will loose 1-2% of battery each 2 hours (at least my X10 R1FA016 and two of my friends X10 R1FA014 do). This is with 3G on, wifi sometimes on, GPS sometimes on. Just give it some time. I think the X10 is one of the best smartphones out there. There is an extensive thread on Power Usage which can be found here: http://forum.xda-developers.com/showthread.php?t=657265
In the end it comes down to:
-Give it some time
-Disable auto search for software updates (settings>about phone>update)
-Wifi seems to drain sometimes
-Streaming drains.
Thanks for the pointers Vin87, I have got wifi turned off now but I am at work for the next 7 hours and I only have about 28% charge remaining
I'm going to have a good read through the thread you mentioned all 50+ pages LOL.
I do like the phone and for the cost I am going to keep it and hopefully we will get some new updates soon?
It gets better...way better. 13 hours since my last charge, and it's at 71%. I've been using it every now and then, Facebook, sending emails ect.
Great battery life now!
From a work perspective, I miss the X10 having a dock.
With my G900 each time I returned to my desk,I would throw it the dock and so it was receiving a charge throughout the day, the X10 is more fiddly as you need to play around the the flap and then figure out which way to plug in the mini-USB cable...
I wish they had chosen a better connector than the mini-USB as the standard, as it's not that easy to quickly connect it....
I could almost throw my G900 at the charging cable and it would connect.
Basically (if you want to use the smartphone):
1. In the beginning you will use the phone a lot. Installing apps, trying apps, games, music etc. so the battery drains faster. When you will stop pushing the phone to the limit will be better
2. Wait for a week, the batter will get better.
3. Get a task killer/boot manager and set it to autokill moxier. Don't kill other apps
4. Set facebook/twitter sync at 1h (or more) if you are not a hardcore fan of this social platforms.
5. Email: if you need instant notification there is not much you can do. If you don't need it, disable background sync and sync manually.
6. Disable location using wireless networks.
7. Wifi/3G: if you need instant notifications, wifi will drain your battery pretty fast but if you don't have 3G data plan like me, there is no other choice. If you have a good 3G plan, you can set wifi sleep policy to turn off wifi when phone goes to "sleep". Also, you can use this together with Juice defender free to turn 3G on 2 min every 3min to get notifications so, you will save even more battery.
8. Enable bluetoot/gps only when you use them and keep them disabled when not.
9. Set brightness to manual and around 25% when you are indoor and "sleep time" (screen timeout) to 30sec
10. Oh, i forgot, disable search for software updates and if you didn't install too many things, try a factory defaults. Some people did a SD card format (be sure you save everything first) and reported battery improvement.
If you want to use the dumbphone inside then turn everything off (BT, GPS, 3G, WIFI, Twitter/Facebook, email, background sync, etc.) and your dumbphone will last way longer
