Charging strangenesses

I've noticed that when the phone is on and the GPRS connection enabled the device doesnt charge itself FULLY (upto 100%) during THE WHOLE NIGHT LONG charging in the cradle - only till 94%. I have to take it from the cradle, close GPRS and put it again into the cradle. Only after such dances the charging proccess goes on and it takes about 10-15 minutes to receive 100%.
Is it a bug or a feature?

GPRS attaching should not consume any power ... but GPRS transmission consumes considerable amount of power .. maybe that's why you can't reach full battery if you leave MSN on for example

But it is in the cradle THE WHOLE NIGHT LONG. It have to be charged FULLY not depending of working any apps at all.

if you look at the xda2 when it's charging then you'll see that it's by no means charging all the time
it's only charging when the led is orange
when it feel that it's full then it start to blink green and use it's batt
then when it's batt % get lower then some lavel it starts to charge the batt again
when it's in the cradle it dont get power from the cradle
the cradle just charge the batt
so it cant charge the batt 100% and then get it's gsm and standby power from the cradle it have to get it from the batt

In other words, you wonna say, that 94% is the cut-off level for the proccessor to begin real charging battery proccess when going from 100% down?. And I hit this moment every time when I waking up in the morning?

i dont know

neither do i

try turning flight mode on then charge the phone. I sometimes get a 100% charge reading because of this

yes, of course. i know that. the question was - why?

we cant know for sure but maybe it's something to do with the batt measure have issues making a good measure at the same time as the batt is being used

i also have this problem in charging my xdaII. when i'm charging via the supplied power supply/charger, i'd only get 94% or sometimes 97% charge (even if it was charged the whole night, with the pda off but phone on). however, if i put in on the cradle (with the cradle connected to the usb port of my pc, but no power supply connected to the cradle), i'd get 100% charge after 10-15 minutes, the xda having it's pda and phone on all the time. what gives? :roll:

Main battery falsely shows empty after charging

I have a really big problem that won't go away, even after 2 warranty replacement devices, new charger and battery.
I use my MDA Compact for a while until it needs charging. I put it on to charge; at this time the backup battery shows 100% and the main battery say 17%. After a couple of hours showing the steady orange LED I turn on: now the backup battery still shows 100% but the main battery shows empty. If I fiddle around doing soft resets and taking the battery out and putting it back in again I can usually get the MDA to show that there is 100% charge in the main battery. The battery is charging, because I can then use the Compact again for 2-3 days as normal, during which the battery level slowly decreases in response to usage.
This problem has me desperate. I have sent the device back and had a replacement twice, to no effect. The last time I sent the charger and battery as well, and they are supposed to have been replaced (can't tell if that's true or not). I've tried only charging from mains charger and not from USB. I've tried hard resetting and not installing any software. None of these helped. I use the same SIM in my XDA1 without any problems, and use the same USB port for syncing, again with no problems.
I've seen several threads about the backup battery reporting empty, but none about the main battery. Has anyone else seen this? Any suggestions for stopping it?

Qtek 2020 - Can't recharge the battery

Hello,
I bought a second hand Qtek 2020. The seller didn't have a cradle, but he gave me a USB sync/charge cable and a AC plug with USB slot. So I insert the one end of the cable to the PDA, one end to the plug and I recharge.
The device came with 90% charge and I could easily charge it to 100%. Today, I ran it down to 0% and now I can't recharge it!! Every time I turn the device off and plug everything in, it starts to recharge. The led on top shows red. It charges for about a minute and the device wakes up. The red light turns yellow. It says on the screen that the device is still charging but the meter is stuck at 0%!!!
I've been trying for hours but I can't even get to 1%. Maybe it would be better if I had a cradle but that's not an option now. Besides, it recharged beatifully yesterday.
I have a feeling that if I can stop the device from waking up automatically when charging, I can recharge fully, but I don't know how.
Any help will be very appreciated.

Update
Here's a quick update. It's gone from bad to worse. Now I only have a blinking red light and the device doesn't come on at all!!
Any advice please?

Have you made sure that the plug is connected tightly to the PPC? If the charge isn't being held, then the battery might be the culprit.

li-ion batts have a limited number of times it can be recharged before it's lifespan is over
maybe your batt's time is up ?

Follow-up
OK. I bought a new battery and everything works fine now. So if you're having a similar situation, a new battery may solve your problem too.

same problem
I had the same problem as you. When the battery was on 30% to 90% it could be easily charged via USB from PC or via usb adapter. Once the battery fall under appr. 20% I was unable to charge it. I wanted to throw to the garbage. I have done many upgrades many resets. While the qtek was without any software (nothing was installed on it) tha battery successfully charged. So used the qtek as ussual and tried to charge it before 20%. BUt now it fall again under 20% and it's happening the same, I can't charge it. The other strange think is, that I have tried 5 computers with USB.1 and USB.2 but is didn't help. Only one computer can charget from 0% to 100% and this one is in my work.. very strange and don't know what couse this... Normaly the battery holds power for two and half days, so don't wan't to buy new one now. If anyone has any explanation why it can be charge only with "one computer" or what can that couse, I really appreciate it.
Thank you

charging problems

Hi guys asked it once before in battery section, but no replies.
My HD doesn't charge auto, when I press the on button the battery charges for 15 sec. tried a new battery same result. I know it Physicly charges, when I charge the phone by pressing the on button a couple of 100 times (really 100x) I get 1% charge. So don't say 'HTC phones only charge when on', cause I know.. Tried a Hard reset 2 times no luck. meanwhile my batt. is dead. So I can't try other firmware.(need 50% charge min)
(chargers are fine)
In short, anybody ever heard of this problem before with other htc models/HD ?
Physicly it charges, so would a firmware change help?(then I need to get a standalone charger/new battery with charge).
My last option is to bring it to HTC but that would take a month
Sorry for number of words on this lazy sunday.
Update - firmware update doesn't work.. next is radio....

no ideas anybody?

Hi,
Unfortunately I dont know much other, then charge the battery in another HD up if available (maybe u can ask in a telephoneshop or so) and then test the Firmware changes.
Is the same if you charge it via PC/USB?

thx for the reply, did just that, changed Rom/radio, official and dutty's rom's, no change. No problem sync. have atleast 3 usb chargers none of them work. When connected to usb cable 2 lights blink 1 green 1 amber one after each other. just like a new message/ low battery even when battery has 50% I get the same light patern, (this is a new battery).
The thing is when the battery is completly flat it stil charges for 15 sec then it turns of. So when I charge it 15 (x15 sec) times or so I'm able to turn the device on again. But when it has (some) battery power the lights start blinking again and I'm completly unable to charge the battery.
The phone is almost 2 weeks old and charged normaly until I checked the "don't charge when connected to usb" option in the power menu. ??!

Then I think you wont get around, to send it back for repair.

have you tried to charge it with a wall socket or is this only when you usb to pc charge??

I never charges, wall/usb doesn't matter.
I just used another HD battery to restore everything to default, So I'll guess I'm taking it back..
Thx anyway.

exact same problem
Did you get anywhere with this problem? I have been strugling with the exact same thing... I have tried all the same things as you, only sometimes it seems like it might be the battery contacts.. I havent been able to consistently get it to work but sometimes if I firmly press the battery against the contacts it will behave normally

Nope tried the contacts but they work fine, battery just won't charge, do your light also blink? (on the power button).
I haven't found any info on the web?!?:S

Problem is solved.. had to be sent back to HTC for repair, it took less then 2 weeks (door to door) so that was pretty fast. They swapped the mainbord, so I got my 'old' phone with a new imei.
So don't waste your time with software up/downgrades. It's a hardware problem.

I had a very similar problem.
Once my battery died some app hung system all night.
No charging at all wall charger and USB 1 day each and so many manipulations. The indicator blinks momentarily and then nothing. I didn't try (didn't know) the key presses like Dogtag. Did a hard reset still nothing...
Then thought about charging the battery with external (Lion) charger before sending for repair. I also shorted the battery compartment pins momentarily. To my pleasant surprise everything back to normal
So far no problems after that though I never drained my battery to zero.
Looks like something to do with corruption in battery calibration data - may not be in ROM?? who knows??

fantastic. can u elaberate?
hey Cragee
I did't understand what u did. Can u try to explane it to me one more time?
I'm realy excited about a posible soulution
hooray

Only two things I did can matter -
1. Charging the battery after taking it out (with a battery charger*)
2. shorting pins in the battery compartment after taking out the battery. (Warning: not on batteries)
Don't know which of the two worked.. No harm trying both anyway.
* U need a Li-ion battery charger - else invitation for trouble including fire and explosion.. These are available in electronics shop at a reasonable price.

Short-circuiting the battery pins... seems to work
I had the same problems with my Touch HD the last few weeks:
- stopped charging after a few seconds
- didn't charge at all (nor the wall nor the computer method, on or off)
- well... it charged sometimes but randomly, keeping it on a wall charger (on OR off) for a night could bring it back to 20% and then rapidly back to 0%
- no charging indicator in the screen while turned on
- blinking orange and yellow (?) light even while turned off
- charged almost never to full and 'jumping' from high to ultra low capacity when turning it on & off
So before bringing it back to the store i tried to short circuit the battery pins as suggested (while the battery and charge were unhooked) like the thing you would do to clear the CMOS memmory of a PC in the 'old days'
And for now it seems to work, at least the charging icon is back online!
I'll keep you posted on longer term results!
Update: I switched to the wall charger and the HD died again??? Now it's back on the computer and it seems to charge fine... why????

When u say "shorted the battery" do u mean, turnoing phone off, taking battery out, connecting the 3 battery connectors with a wire for a few seconds?

....so what does shorting mean??

I thing so. You should circuit the pins WITHOUT battery. In any other case it may occurs damage on the telephone

Dogtag is right... it's defenitly a hardware problem
As posted before...i had the same problem with my touch HD, charging was a pain or sometimes seemed impossible. The phone was repaired twice.
-First they replaced the connector - no succes.
-Second time the replaced the motherboard, and everything was solved.
So imho it's the mainboard of some machines, i still wonder if it's a factory problem or a 'fried' chip of some kind after a bad charging procedure? Bad USB car charger of some kind?

Turn off USB Charging for Omnia (solved)

Hi all, there is a way to turn off the charging function when using USB ,
1-install FdcSoft TaskMgr from here
dotfred.net/TM/FdcSoft_TaskMgrv3.3_WM6.5.cab
2-go to Devices--->$device\BAT1(BAT1 and stop this service
3-thats All
To Use charge restart this service

hey thx for the tips! but after stop the service my o2 keep saying batt low...

Is there any reason why we would want to turn off this service?

I heard that it keeps your battery in good shape

I'm not so sure about that... I've always charged both my O2 and the O1 before through usb and the battery has always been fine.
Actually, I even noticed that charging through usb takes longer but once it's charged it also lasts longer (this happened on the O1, haven't made the same comparison on the O2 yet)
Dunno if plugging / unplugging the usb cable too frequently can have some sort of ill effect on the battery life, but it's not like we're plugging it every 10 minutes is it?
Never had a battery problem with a "normal" usb usage and usb charging enabled so far...

Yes but not anymore

It's always good to drink all the juice so the battery don't develop a offline or fake "memory".
Also the multi cell assembly insde the battery praticly don't allow batery memory anymore.
Thx for the reference

Regarding battery life
Hi,
Actually, for a battery it depletes it's life every second. There is no way of preventing this But we can extend the service life. For example the most basic rules:
1-Do not charge your battery unless it is almost empty
2-Avoid deep discharging (this is not possible with a PDA coz it has an early shut down routine)
3-Do not overcharge the battery (also this not possible, coz there is a voltage limiter by hardware)
4-Do not leave your battery in a high temperature environment (for example in a car during summer, we are using chemical-reaction batteries)
the rest is do not puncture, do not short circuit boola boola boola
ok, finally while using your PDA with a USB charging interface, it should stop charging when the battery is full (Even my mother's old nokia doing this)
Plus, how much it costs for a new battery? only few bucks.. ehh.. (not for an original one ofcourse)
PDA batteries, in most cases, are 3.7volts (charging voltage is 5volts by USB) and 1200 to 1500mAh (for the ones who doesnt know what is "mAh": it is the capacity of the battery and it means if you pull for example for a 1300mAh battery, 1300 "mili ampers per hour" it will deplete. Some of my friends they are using 3.7V 2000mAh batteries while their PDAs supplied with 1230mAh batteries, thus, standby time goes up to a week. They are not using their originals ofcourse. I dont understand why manufacturers are not supplying PDAs with these kind of batteries by standart. Even a chinese made battery can be so efficient. (I am using a chinese one, my original battery is 1300mAh, i could find 1500mAh same battery)
I spoke to my friends, they are not charging their 2000mAh batteries via USB/charger while battery is in the phone. Because there is an internal electrical resistance of every battery. May be PDA's battery charging circuit get damaged! Because of this if you plan to use a high capacity battery, charge it seperately by using another charging equipment.
Finally when you want to sell out your PDA install the original battery (which you have never used before hehe ) and get a higher price

This might be some really big idiotic question, but what if the service is down and the battery drains and the phone shuts itself off, will it turn on by connecting the charger to the phone?
I ask this because with the service off even the real phone charger wont work (at least while it is on)!

I just did what you said, and now the device\BAT1(BAT1 completely disappear! How am i supose to turn it on again now?
And no, i obviously didn't delect it, i just stoped the service and it vanished from the damn list!

im very interested in this but how can you restart the charging service?
