I've had an o2 mini s for about a week now and i'm pleased with it on the whole. My only real concern is battery life. My mini seems to drain much quicker than by xda 2 s which I had before. I seem to drop about 10% in 1 hour 10 mins and that's just a few calls/txts and minimum fiddling.
8:20 100%
9:42 88%
I've dropped all the o2 software and don't have any tricky 3rd party apps installed only;

I've read quite a few posts about battery life being good on this phone but i'm not seeing it. I'm still in my 14 day cooling off period and i'm considering sending it back for a replacement.

Is Wifi off, bluetooth off. Do you check your email every ... minutes over GPRS?...
With email checking every 10 minutes my qtek battery last at least 2 whole days.
wifi/gprs/bluetooth all off - not used today
Just phone today - maybe 12 calls.
Time now 14:21 battery at 61% !
Now i'm worried ......I reckon i'll be down to 30% by this evening.
16:32 - 49%
maybe there are problems with these batteries i had problems with charging the battery it didnt seem to show correct level, sent it back for another unit
17:26 - 38%.
If another goes we'll be up here all day.
My battery life seems to be utter rubbish every time I charge my MDA Vario over the USB link. I can go to bed with 100% battery and find it dead by morning. This has happened two or three times since I bought it on 5th November. Last Saturday morning I had the USB cable connected to download some music to my SD card with 100% charge at 10:00. I played music for about an hour through the supplied headphones and by 13:00 I was down to 50% battery. By that evening I was down to a few %. I've read reviews that you you should squeeze about 10 hours of continuous music from this thing on one full charge so an hour of music and 7 hours of standby/sleep seems pathetic.
If I charge using the mains charger and sync over Bluetooth I get a standby battery life of about 5 days. Obviously that is shortened with use so in practice I am charging it every 2-3 days (no point starting a day with only 20% left!).
I have no idea why USB charging is completely hopeless. I have tried soft resetting or closing all active apps after charging, to make sure ActiveSync isn't actively running and causing a drain (just as you are advised to with a Bluetooth sync) but that seems to make no difference. USB charging is rubbish. Mains charging is the only way to go, IME.

I confirm USB charging IS rubbish. The reason seems to be that the power available out of that conector on a PC is not enough to charge properly... I had the same issue with BA and Himalaya...
Answer: get a USB charger / car charger that can deliver 1A minimum.
BTW I found a craddle for the Wizard in Dubai @ Plugins. It comes with USB port/cable + power adapter. Works like a charme.

My C500 Did that when I had it Plugged in the Front USB ports on my case, I normaly had it plugged in to the onboard USB at the back of my pc with a usb ext cable so I could have it on my desk but I went off to a lan party and when I plugged everything back in I put my USB cable to front usb port and found it was Discharging my Battery instead of charging it, got my usb in Back port all is fine again now
Maybe you have yours in to the front USB port or non onboard port?
I use a laptop, which only has two USB 1.1 ports but they each supply enough juice to power a USB ADSL modem (not that I'm using one of those these days), which is more than some PCs will manage and also my USB hard drive, which my Shuttle won't. So there is no lack of power from the USB ports on the laptop.
Of course, the USB spec only permits a maximum current demand of 500mA so any equpiment expecting more should not be using USB for its power supply. In any event, the phone does charge from the USB ports, albeit very slowly, but eventually the orange charge light does go green. So my situation is not one of discharging instead of charging.
I've just swapped my ROM from Vario to k-jam so I'll see if that makes any difference to the performance. I know it's given me 802.11g, which was missing before.
I had an M500 briefly (Magician) on Orange that had very poor battery life, it was one of the reasons I ebayed it, gave the contract sim to my wife and started a cheaper better value T-Mobile account with an MDA Compact, which
had better battery life. Typically overnight after a full charge the Orange unit went down to 75% and the T-Mobile one was at about 98% on standby.
My Vario I have now, my other T-Mobile account has very good battery life and charges very well off USB. If I sync it in the morning whilst reading my emails and stuff, let it charge USb for about 25 mins, it'll be full and by the night it will have dropped down to about 80%. This is with about 30 mins of calls, about seven or eight emails sent/received and maybe 15 mins with WIFI on.

I can't remember for sure where I got the k-jam ROM ( I think someone saved a copy somewhere) but try here - ftp://ftp.clubimate.com/ - and then save file K-JAM_WWE_1010903_106_10110_ship.exe
That is a self installing upgrade that includes the whole k-jam ROM and k-jam extended ROM files.
I don't know where to get a Vario ROM from. I did back up my own copy (I hope) but the method is a bit whacky and as I only have a 1GB mini-SD card my ROM backup image is 1GB because the only way to secure the image is to dump the whole card to a file.
Before you go playing around do make sure you have your own backup of the ROM or if not the whole thing then the Vario extended ROM files at least. I'm using the k-jam ROM with the Vario Extended ROM.

Hi,
Is there any way to disable USB charging? I didn't connect USB very often since it will charge automatically and I don't like the battery be charged very often. It might kill battery soon. I like to sync with bluetooth; however it is much slower than USB. It's amazing if there is any tool to disable USB charging. Because it will sync fast and will not hurt the battery. Thanks for the suggestions in advance.
Cheers!

You are thinking of older batteries such as Nicads. Topping up often does not hurt Lithium batteries, in fact it's better for them. Their main enemies are deep discharge and heat - and that's exactly what you're subjecting it to by letting it run flat, then charging for hours to get it back to max.

Dear Ineedtoys,
Thanks for the reply. I understand that there is no so called "memory effect" on Lithium battery; however when I checked the battery spec, I always found that there is a "charging cycle limitation". For example, a specific battery claimed that it can be rechaged 10,000 times, then very USB charging will be counted also. It will reach 10,000 times faster. This is my concern. I don't know if this is right or wrong. Can somebody help to clarify this?

That's true. It's the same with Notebooks. The more you charge it, while it's in use, the faster the battery gets "killed"!

Answer my own question.
I am quite sure that the USB charging can be disabled since I used to see the config on a HP device. I also believed that this can be done by 'registry' since it is Windows tradition. I finally found it after a short study. Please go to
HKLM\Drivers\BuiltIn\usbfndrv
and change the
EnableUsbCharging to '0'
then
soft reset => Bingo.
Hope it helps.

Having major issues with my 3 month old XDA.
1. Will charge when using the home charger
2. Will charge when using cradel connected to 1 of my 2 PC's
3. Will not charge when using cradel connecting to my other PC
4. Will not charge when using cradel connecting to my MAC
5. Will charge when using cradel connecting to my PC Laptop
6. Will not charge when using the O2 supplied car charger
In every case the phone thinks it is charging i.e. the green charging light comes on and if you go to the battery control panel, it even says "charging".
XDA repair centre have had it for 2 weeks, flashed the rom and returned it. Still doing it.
Have demanded a new phone form onestopphoneshop.com who have refused due to it being more than 28days old although it has done this from new.
Aaarrrrgggghhhh!!!!!!
Can anyone help?
Have you tried another battery?
Since the hardware 'logic' seems to be doing something (light goes on, software gets charging signals) the chances are the battery is faulty . . .
Why some chargers do work and others dont: Could be the charging current that is higher on chargers (incl USB port of one of your pc's) that make this battery charge.
Battery...could be I suppose, but I have been digging further into this and have found the following.....suspicious!
www.ppcw.net/?itemid=1646
Hello,
I have a very similar problem to that described in the website you listed.
My phone works fine with its supplied cradle and charger, and charges fine with my work and home PC's, with only the USB cable plugged in.
I bought a charger/ sync cable off the web hoping to not have to carry my cradle home each day and it causes huge problems.
First off it doesn't sync at all - but does cause problems with activesync giving me error messages once it is unplugged saying 'Can't access COM1'
Worst of all though it turns the LED to orange for charging, and when you go to the battery screen it says charging, but instead it actually discharges the battery! This is also the case when I use the cable with the wall socket plugged in.
Just spoke to XDA Repair centre, they have done a total cop out and said that they do not support anything that does not come in the box!!!! That means my car and my computers!!!
[email protected]@rds!!!
Have just bought a new 1400mah battery, will be here in a couple of days, will keep you posted.
I have found that the battery will charge if the xda 2 is about 70% full but lower than this and it will discharge the battery via usb.

Just want to make sure, is it 1400 mAh? because the standard one in the imate (xda2) is 1200 mAh.

It is indeed a 1460 battery to be precise, I have been told that they are very rare, think they are the ones that are going in the new XDA II i, s, III or what ever it is going to be called.
It should last 25% longer, cost £25GBP. Will let you know how I get on with it on Monday after a weekend of testing.
Back to the charging problem, do you others who have the same charging problem all use the O2 supplied USB cradel. Is there anyone else using an alternative charge and sync cable that works better???
Just a thought.
I have been told more by the XDA repair centre. It seems that the output through various USB ports vary in ampage, surely some sort of regulation should be made into the cradels/chargers???
not sure if this is relevant but
if one does not connect the power connecter to the cradle
then the xda will be forced to charge using usb
and some motherboard have issues giving enough stable power
more so if you have connected more then one usb device
to ports which share the max 500mA that usb can give
also not all motherboard can charge over usb when
the pc is off it all comes down to if usb is powered with vsb+ 5v
some motherboards have jumpers to control this
canaero - Where did you buy the battery from? Is it exactly the same size, or is it slightly thicker?
I have ordered a mini-sync charge cable from boxware in the states; on their website, it says it is compatible with my ORange SPV M1000, but we'll see when it gets here.

Well, I am using the cradle and I do not connect it to the power supply, here it goes, it takes a lot of time to charge my imate (xda2) if it is connected to my notebook, while it takes about less than an hour to charge the imate if the cradle is connected to my PC!!

That's really good price and I guess the battery performance should be better, I heared the xda3, or xdaIIi or whatever (the new model), the battery power is 1490mAh. Please let us know your experience with the new battery.
The new battery has just arrived and I am charging it now. It says 1400 on the front plus a made in china sticker on it.
I got if off ebay from SIANS Mobiles spares and repair Tel: 07743 787858 or www.siansmobiles.co.uk
Good luck
IT WONT CHARGE!!!
just a quick one, i arrange for around 60 XDA's to be used in my company and i can tell you that not one of them will charge in any of our company vehicals or charge via the cradle.

Yikkkes, O2 must listen to you as you have bought so many, say you will send them all back and cancel the contract and see them squirm. Let me know what the outcome is, because leagaly you can send them back and get our of your contract under 'not fit for purpose'. Do it around the time of the new XDA, who knows!!!!
There really is an answer to this somewhere, I have bought this new high capacity battery and it is still not charging when it says it is. I am off to the Microsoft site to see if I can get them to point the finger and the XDA.
Used the new 1400mah battery all weekend, performed very well considering I used it as a sat nav for 6 hours on Saturday continuously with the backlight on for all of those 6 hours.
Hi guys,
my beloved qtek 9100 is having some weird behavior since last week: i let my battery drain to 9% and then recharged. The phone would not recharge it, showing a red led. After lurking and learning about this problem on those devices I made a "starter" with three 1.5v batteries and gave the battery the necessary tension to start recharge cycle.
I thought that would be the solution but no: the phone kept stopping recharging at 25% or, the next time, at 75% with no apparent reason. Then, i tried many solutions like directly charging the battery with a cut usb cable, with the stock charger, with powered on phone, powered off phone, etc. No clue.
What leaves me shocked is that the battery, even when at 75%, drops suddenly to 0% after enabling the radio module thus killing the device...
An important note: same behavior with two different batteries...
I'm going nuts...
Problem still unsolved. Today i left the device recharge at 100% (took about 3 hours), detached it and tried a rom downgrade. Obviously it died at 50% of rom upgrade procedure. Sweet...now it's almost bricked, bootloader screen and recovery procedure to be done
What could it be, an hardware failure?
Hi there, same problem here: I have the phone with two batteries, on half a year old, one brand new. The batteries DO charge on another phone, but after a regular charge is gone, my phone never gecharges the batteries. It might be the charger circuit? If not HW, is there any chnce to do some SW stuff?
Unfortunately this thing s just a brock now ...
Bye

It's good to find someone with my very same problem...although i've got no solution, still!
Is there someone out there who knows how much would cost a fix and if it's an hw issue or not? Would it be possible to fix it via DIY?
Thanks in advance
Someone suggested me to test the current output on the main contacts to see if the device is actually supplying power to the battery.
So i plugged the wall-charger on the device, took a multimeter, checked the output: the device is supplying 3.5-3-7 volts. So, i suppose it is correctly charging. Why, then, after a turn-off / turn-on the charge level drops after showing as completed?
Could it be a sw problem, then?
USB voltage is 5v. If you are not getting 5v on the USB plug coming from that charger, then that is probably your problem. Have you tried using a USB cable to plug it into your PC to charge?

I suppose the problem is another...in fact those 4 volts are coming from the battery itself. Pluggin in or out the power plug doesn't make any difference.
I tried taking out the battery and there's no power coming through the main contacts of the phone. Is this the right way to check or should i use some different method?
Thanks again
Last question: is there someone who could show me where the recharge circuit should be on the mainboard? Have you got any information about the ease of a diy repair and about the price / availability of the spare part?

Are you using the wall charger or with the PC. Cus you will get more power input from the Wall. As so i dont know the reg key off hand but if you change one thing you can make it so your phone does not charge off the PC. Maybe you have found a new one!

With both the wall charger and the pc usb plug. Checked the registry key and no way, it's ok.
It's really incredible, the total charge cycle takes a couple of hours, like if it were charging regularly, but after unplugging it goes down. It is like if the "carge counter" or similar records the charging, with the battery actually not receiving power.
did you solve your problem yet?

Hell...no!
Hrm.. This is interesting.. I used to always charge my G1 with AC power. However past couple days, I was lazy and used my laptop USB to charge it. I noticed those days however the battery life was HORRIBLE! I mean I couldnt even get past lets say 9 hours without the battery being at 15-30% and this is without doing anything major. On AC I always got home with 50%.
Has anyone else noticed this? I am using the power profiler mode, so unless something goes out of whack on USB power mode, which I dont see why it would...
(Also I did turn off phone and back on to reset anything just in case) but its just a interesting thing that it seems USB charges suck?
Yes I noticed the same thing, used the computer USB to charge and only lasted about 6 hours of the day. I use the Wall charger and get about 9 hours consistantly. Not sure why but I have noticed this several times........
Mark
Every Tmobile rep I've talked to always say the AC charger does a better job of charging the phone.
Hrm, is this info on a G1 Wiki yet? Would be good info to pass around. My logicial guess is that USB charging can only allow the voltage on the battery to charge to "x" max. While AC power being stronger could bring the battery up more. I cant say thats fully the case.. but since the USB cannot supply the power max a AC could.. its possible.
I've got and idea for a little test, would be helpful to see a lot of different users results as well..
Get Battery Graph, run your phone dead, plug in usb charger and graph. then take a screenshot of the overall charge time, clear graph
Run it dead again, plug in AC charger #1 and and repeat
Repeat the process for each additional recharging apparatus
The reason I mention additional apparatuses is because I think my car's DC charger does better than both ac and usb (tho this will be hard to get a full accurate graph of) , also I use my gf's moto charger from time to time (i know bad mojo)..
This will probably take a few days as charging will take place at sleep time for me but this should give us an over all view of how things are working if we all get pretty consistent results..

I've had 4 different miniUSB charging phones and all of them have had this same behavior. I'm sure that the voltage coming through the USB isn't as strong as AC.
I have the same issue too...!!!

Im wondering, if I use my usb while plugged into my laptop (for tether wifi app) will this hamper my battery life? I have the extended battery (2200mah) and I get far better life from it and to be honest I like the bigger size because the g1 felt too much like a toy to me before.
What do you guys think will this mess it up? I dont have wifi at home so the tetherwifi app is the only way I have net on my laptop unless I go somewhere where they have wifi. Cursed neighrbors and there password protected networks!
Might using a USB stepup voltage converter help? I've used it to charge my Nokia phone on usb in the past so it would reach the battery is full message.
The argument is usually that laptop usb don't output adequate voltage.
Its cheap and works for me on the nokia phone, Haven't tried it on the G1 yet though, can anyone find the ac charger's output info?
http://www.dealextreme.com/details.dx/sku.2649
yea this goes for alot of devices.. my ipod/psp charge pretty slow compared to wall outlet, however i didnt really see strength difference.. never tried USB charging my g1
I think it's worth noting I have the G1, My girlfriend has a HTC Touch(Elfin)
Both use Mini-USB Charging, both have 5V 1A Batteries (can't remember mA rating though)
Through a wall charger, my phone seems to charge quicker, but I get no longer out of it, the same behaviour is exhibited with the Touch. Both USB and the Wall charger are rated at 5V (It would/coul destroy componants methinks if it was any higher).
USB's Specifications say that unless a device has special permissions, It can only draw 500mA, with a maximum of 1000mA and a very rare (as in, one maybe two things use it) 2000mA.
Also, I have a custom made USB charger, that takes 3 AAA batteries (1.5x3 = 4.5)
It causes the phones internal battery to mess up, but does actually charge it (just a lot longer than other methods). It's more of an extended battery however, as it says it is charging, yet the battery life slowly degrades.
It's simple really and it has already been explained.
The USB port on a computer is limited to 500mA for most devices where as AC chargers like
The G1's can rpovide up to 1 Amp, even more/less depending on the chargers.
It doesn't depend on the voltage but on the current delivered. Less current equals
More time to charge and viceversa,
There is no myth.
Hi all,
My TD1 would charge from any mini-usb charger (such as the one I have with my TomTom). I put the TD2 on charge from one of these last night. The front light went orange, and the battery status changed to charging. However, I wake up this morning (7 hours later) and the light is still orange. I disconnect and look at the battery info and it says the last charge was yesterday.
Is the TD2 fussy about which charger you use? I really hope HTC are not pulling an Apple and locking their devices to only their accessories!

My TD1 would charge from any mini-usb charger (such as the one I have with my TomTom). I put the TD2 on charge from one of these last night. The front light went orange, and the battery status changed to charging. However, I wake up this morning (7 hours later) and the light is still orange. I disconnect and look at the battery info and it says the last charge was yesterday.
Is the TD2 fussy about which charger you use? I really hope HTC are not pulling an Apple and locking their devices to only their accessories!

I think I remember reading something about an option for not charging the battery when connected on PC USB (presumably for saving laptop batteries ;-) ) in the manual.
So I guess that the TD2 has a way to detect if it is plugged into a charger or a laptop, and maybe it can do that only with HTC charger, believing your charger is in fact a laptop. I would have guessed they use the activesync status to differentiate between PC and charger, but maybe not ;-)
So what could maybe solve your problem is to select "charging battery if plugged to a computer", I think it is in the touchflow 3D options somewhere... I would play with those options to check if it improve things...
Settings - All Settings - Batter - (Battery Tab). "When device is turned on, do not chagre the battery when connected to the PC.".
For me this is unticked - and when it was plugged in the battery reported as 'charging'.
Strange!

Does it work with the standard HTC charger?
And plugging to a PC?
If yes, your other charger may be a little light in specs (amperage too small, or voltage slightly below USB specs) and the TD2 may be picky regarding this...
I would also inspect the microusb plug of the charger to check for dirt/corrosion/deformation, and also the battery within the device: I already had intermittent problems like that caused by imperfect connections: the device was in a charging state, but no actual charging did occur. Replugging carefully after blowing on the plugs solved the problem....
From past experiences, all my HTC phones charges up with any USB cables or chargers, even my HD. So may your battery is not working some how... best thing to do is try charging it with your original charger or connect your device to your computer, it should charge up. If not, then take it back to your dealer man! I don't want to say it but maybe you have a lemon...
Hi all,
It charges well from the supplied wall charger. It also appears to be charging well from the computer. So, this leaves me to suspect the other (non HTC) charger.
Thanks for your help....

OK - this just getds weirder and weirder...
Yesterday, plugged into PC all day whilst I was working. After a while green light so fully charged. Went out for an hour or two and when I came back I put it on a different wall charger for a test (my old TD1 one) and after 30 mins or so green light - so fully charged again.
So, I thought - this is great, it proves the other wall charger has a problem. Before bed a few hours later I took the TD1 charger and put it in the bedroom. Plugged the TD2 into it overnight. Woke up this morning, and orange light???!!!
Put it into the computer this morning and after 15 mins - green light???
CONFUSED!!!
Could it be some function whereby it won't charge a bettery that has been charged full in the past x hours or so??? Is anyone else seeing anything like this????
R
I think you have might have a duffed battery. I think you should really check it out.
I use a Motorola universal mini-usb charger i mine car and I haven't noticed any different behavior than using the supplied HTC charger or HTC usb cable in my laptop..
I put it on the supplied charger for 12 hours and it did not charge at all despite the orange light being on. As I am within 7 days I've asked DeviceWire to refund or replace...
R
Way to go, you should get a new one!
check the connection!

First of all, yes you are.. IF the device is faulty!
from experience, I know that some cables dont charge the device.. First of all make sure there isnt some dust or stuff in the connection. secondly, try resetting the device.. If the orange light is on, then it only means some of the pins in the EXTusb connection have been shorted, my reccomendation, check the pins on the miniUSB connector on the phone, and make sure you didn't bend some.
Hey all,
No bent pins.
No dust or dirt in the socket/plug.
Tried 3 (HTC) wall chargers - all the same behaviour.
Tried resetting the device.
No luck

I especially used my USB-Charger this night to charge the device.
It is a Hama USB Charger (Prod# 00014095, you can find it with this on google).
It has an output of 800 mA, while the original hast 1000 mA.
But it charged up to 100% and was "green" this morning.
So it seems to work and is really Small in size
Regards Thorsten
Well, this has been a problem for me from the start and all I have used are HTC chargers. I've not had anything like this sort of issue with the previous HTC phones I've owned (and there have been a few - check sig). What confused me was that it does appear to accept charge from the USB port of a computer - which is just odd??!?!??
Anyway, I think this is unacceptable from a new product so I've asked for a refund/replacement. Awaiting a reply from Devicewire.
R
Whats weird,
My TyTn has some probs in this department.
From time to time, setting it on USB power, will not even lit the charge-light.
And it will not charge.
I have to reset it and then it works.
Dont know what that is.
DeviceWire sent me an RMA. In the meantime I hard reset the device again after confirming that the wall charger would not go above 89% charge - 9 out of 10 bars (I installed a prog to give me a % reading).
After hard reset the battery went from 89% to 100%. I am now running it down again - before I give it one last chance overnight. If I wake up tomorrow and it is still orange and at 9 of 10 bars then off it goes...
R
Fingers are crossed for you mate! Hope it goes well.
This just gets stranger - after *this* hard reset it now appears to be working as expected - woke up this morning to a green light for the first time!!
So, was this just a software thing - solved by a couple of hard resets - or might there still be a problem lurking underneath???
Problem now is that if I send it back to DW they'll confirm it is working as expected. If I wait and do not send it I run out of the 'return within 7 days for a refund' and will have to reply on HTC aftercare (horror!!).
What to do!!!???
R
I'd still return it but in your RMA notice stipulate that you suspect the problem "seems" fixed but say it might come back again and on that note are still returning it for a replacement/refund.
Strange Question? When my battery dies in the past I used to just plug it into my pc at my desk... DELL T5400... and charge the phone up again.
Though lately I have been using a hard-drive cable and I can't seem to recharge my phone on any pc??
Though I can pretty much download all the information from the phone??
I do have the dutty rom on.... though I don't think that would effect it?
Does any one have any ideas?
Under "Settings -> System -> Power -> Battery",
you find the option "When phone is on, do not charge the battery when connected to a PC".
Perhaps its activated?

If you have let the "battery die" over and over you could well have sent the monotoring circuitry below the charging cutoff point which is voltage dependant.
If the battery still charges from a wall outlet then this is more than likely the case as your wall charger will be rated at 1000mAh whereas the USB port is only 500 mAh max and if you have other devices plugged in at the same time it could well be a lot less and this will now no longer "start" the charging process.
If all this is the case then you have trashed the battery.
If not then charging through the wall socket could partly recover the situation, if you are lucky!
When (if) you get a new battery then keep it on constant charge (wall outlet, USB, car charger, external battery pack etc,etc) as much as possible and try to avoid a full discharge.
You guys are great
Thanks Guys that helped a lot.
I have always been scared of discharging the battery completely, Thank pa49 for confirming that.
I found the default setting for the battery was what jkolner said, Thanks bud .
I appreciate the help
