XDA II Charging

I read a few articles about the auto sync (usb) cable.
There seems to be a "bug" when charging with this cable the battery charges till it's full (100%) and than discharges the battery again.
Is this is the same with the usb cradle?
Thanks
Panja

Is the cable you are talking about a charger to run from the USB port of a desktop to the XDA, without the need for the charger? Where can I get one? I only got 1 power charger & keep it at home (where I dont have a pC) & my cradle at work (where I do), it would be nice to be able to charge at work too!
Does anyone know where to get a new charger adapter plug from (the one to use for charging without the cradle) mine is getting a bit knackered!
cheers!

Don't know m8.
I was just asking around because I read stuff about it on some pages.
try www.expansys.com
Can someone answer my question.
Thanks

Has anybody used a usb sync & charger cable for the Himalaya (XDAII) ? I would like to buy one which works for sure. The one from Lil'sync did a very bad job cos it sync's only without charging.

I was the one who started the thread about this problem with the sync'n'charge cable. If you read my posts in the following thread, you will see that the cradle doesn't have the charging problem:
Sync-charge cable charges to 100%, then discharges

thanks for the reply m8
Will be looking @ your thread in a few secs.
cheers

Oh No ..... I didn't realise this ... and I've got one on the way to me. By the way I take the cradle to work every day but leave the mains adaptor plugged in at home. The cradle with just the sync cable is quite capable of charging the phone at work, and I'm sure once it gets to 100% it stays there.

battery life concerns on wizard

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!
Michael

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?
B. Rgds.,

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.

Wizard looks like is recharging, but in real it doesn't!

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?
Thanks in advance

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?

Faster USB Charging?

I remember on my WinMo phones there was a program to speed up the charging through a USB port. Anyone know of a similar app, hack, what have you for our Heros?

you could try a wireless charger, or use the normal wall charger or get a 3rd party battery.
I use a 3rd party battery, and my phone charges from Dead, to full in under 2 hours. i think my brand battery is a radioshack one but i dont remember, and im too lazy to look lol

If the phone detects that it's hooked to a USB port, it'll charge more slowly because the typical computer port will only output 500 mA. A wall charger typically does a full amp.

There is no point in "tricking" the device to think it's the wall charger because what you want is the phone to charge up, not to beleive it's charged up when it's not. The usb port will not output more than 500mA. The phone will only charge as fast as 500mA will get you, no matter what tricks we try to pull on them.

Actually, most USB 2.0 ports can unofficially support up to 1000mA (which is indeed out of spec), with the only limitation from the device itself which when in spec will not draw more than 500mA. This is why no2chem's Fastcharge worked on WinMo phones, by increasing the maximum limit on the device.

I don't know where you're coming from, but the phone will indeed pull more current when it detects it's on a wall charger. I specifically remember seeing it in the manual.

Has anybody heard anything new on this matter, I really hate not being able to charge at 1A from a computer USB anymore. 500mA is pretty much useless, especially in constant usage, it pretty much just maintains the current %.

from less than 10% to 100% in about 30 minutes when plugged into the wall...turn your phone off while charging!! itll charge so much faster!!

This was specifically about usb....

I seem to remember hearing you can tweak some usb wires (I guess remove the data pins) so the phone thinks it's on AC but I'd want to have connectivity as well as the swift charging. Otherwise I'd have to have two cords on me, though I wonder if the phone charges "AC speed" while off (since there's no mind to talk to the PC's OS)

Phone stops charging after Oreo Update. (On my second phone right now)

First of all I'm very sorry for posting on a developer Forum, I had lurked here for about a month looking for an answer and I can't find it. I wouldn't had made an account otherwise.
Here's my problem, my phone randomly stops charging (not notice neither) since the Oreo Update. I believe is because of the update because I return my old phone and bought a second phone and decided to leave it on Nougat, I decided to update it to Oreo because I missed notification badges and the day after I already had the same problem.
Things of Notice:
*Both phones where new and on the latest security patch.
*My phone does charge overnight when in wall socket but will stop charging when I used the USB on my car (my car has a USB adapter but if I charge it there, it will keep READING USB and repeating the cycle)
*Phone also stops charging when I use an extended battery. (I'm an avid Pokemon Go Player)
*Restating the phone a couple of times, fixes the issue.
Is there anything that I can do? everything else about the phone works perfectly (Facebook takes a long time to load but that's it). If there's an answer already please forward me to that post. Thanks again

Could it be because the update enabled quick charge, so now the phone requires a bigger energy output from the USB?

Does changing the cable help? If not, try doing a factory reset.

Anywhere from 0.5A (laptop USB port) to 2.5A (tablet charger) should work. Can you test charging from a computer?

I'm sorry I answer this late, I was unable to log into the site from my phone. (forgot the pasword). I did some testing in the weekend and it did charge on my laptop, it charge extremely slow., Just 3% in like an hour. (with constant use).
I kept using it with my power bank it kept charging reliably as well as in my house. But it keeps having the some problem at the car, So here's what I'm wondering. If I use one of those 3.0 USB car chargers will it charge my phone? without a problem to my car? I don't know if this phone supports fast charging (the specs says yes but I never seen the fast charging message with the regular charging)

I'm sorry I answer this late, I was unable to log into the site from my phone. (forgot the pasword). I did some testing in the weekend and it did charge on my laptop, it charge extremely slow., Just 3% in like an hour. (with constant use).
I kept using it with my power bank it kept charging reliably as well as in my house. But it keeps having the some problem at the car, So here's what I'm wondering. If I use one of those 3.0 USB car chargers will it charge my phone? without a problem to my car? I don't know if this phone supports fast charging (the specs says yes but I never seen the fast charging message with the regular charging)

No worries. Yes, laptop charging is slow.
I'm not sure if the stock ROM supports fast charging but custom ones do, and it can't harm your device. I don't see why it would harm your car if it was made for it. Maybe your car's USB port broke.

I see, I'll buy one of those quick charge car chargers and if everything goes alright I'm keeping the phone. I really like the look and camera and my only annoyances with it come from Stock Android.

Alright, good luck with the new charger.

Update: New charger works perfectly, I'll keep the phone. Thanks a lot man.

Could it be because the update enabled quick charge, so now the phone requires a bigger energy output from the USB?

Thanks for posting your problem and the answer!
I have had the same reaction on one of my phones after updating to oreo.
Changing the charger from a 1A model to a 2,4A model solved the issue.
