Big battery problem

I just bought a Kaiser yesterday and i recharged one of the battery for 6 hours in the night and when i got up this morning, the battery was not full but totally empty, i could not even turn on the phone, the LED is red instead of green. i used another charger but still had the problem, the phone always says low battery and turned off, then i measured the voltage of the battery, it reads 3.8V, can this power up the phone?
My question is, if i de-select the USB charging while connected to PC, would this prevent the battery from recharging by all ways?
Please offer your comments, thank you.

Battery charging not possible

Hi,
I have my Diamond for about 1 year now. About three weeks ago I could not charge my battery anymore, so I bought a new battery (original HTC). With the new battery installed everything worked fine again.
After a week the problem retruned. The phone switched itself off after the battery level low warning and I tried to charge the battery after about 5 hours. So a second battery became useless.
I also tried charging by USB-cable with several PC's but without any result. I measured at the + and - poles of both batteries and measured about 0,3 Volts, so the batteries must have been drained completely. I guess the protection circuit in the battery/phone prevents charging.
On one battery I directly put power on the battery poles from another power supply, which deliveres about 10 Volts for a very short time (only for about 2 seconds). Then I measured the voltage on the battery poles; it was about 3 Volts now! I put the battery back in the Diamond and to my surprise it charged normally. I also did this with the second battery and it also functions normally again.
Tonight one of the batteries was drained again and the charger was connected after about two hours and again no charging was possible. I did 'the trick' with the other power supply and afterwards everything was working fine again.
In other situationss, when I connect the charger directly after the phone switches itself off after the battery low warning it also works normally.
The problem seems to be that the phone drains the battery completely when left without charging and when it gets too low charging is not possible in the normal way. The phone swithes itself off at about 5% charge level, so the software seems to be working ok.
Does anybody know this problem, and maybe propose a solution.
I'm using the latest stock 2.03 ROM from HTC.
Thanks in advance!

I'm having the charging issue. Having it with both of batters. Overnight charging and only 40%. Also drains like with in hour. Any solution?

[Q] New battery but can't charge..

So I recently bought a new battery due to the original not being able to charge when it was empty...
The thing is I could only get the original charging if I "jump started" it by using a navman car cable and doing it in the car...I'm presuming it's because the output is 1A and not the standard 0.7A...
It seems that the new battery I bought has the same problem as I let it run out and now it won't charge...
why is this? Is it a problem with the phone itself?
I'm getting a HTC HD2 this week anyways..so it's not a major issue but I would still like to know why...

No ideas on this issue? Or has it been asked before? I can't search the forum says it's down and I should try again in 10 minutes....(Did it when I made the thread and again just before this post)

This has already happened to me before, I thought it was a battery problem so I bought a new one. Sad to say, no change. It won't charge after the battery died.
Symptoms:
1. dead battery
2. red light emitting from power button
3. red light blinking from sides
4. not charging, even if left for a whole day plugged in
Here's what I did:
1. use a different charger, one w/ a rating of .1 amphere
2. wait a few minutes- 10-15min
3. after a while, the side lights will begin to blink to indicate charging
4. you can now turn it on
5. charge normally or continue w/ same charger
*avoid discharging your battery and plug it in if batt life falls below 50%

[Q] Charging Battery so loong...

I charged my X1 with wall adapter. But after 2 hrs, the phone is still charging.
See the battery meter it has reached 100%. Then wait another hrs, the phone is still charging. After almost 4 hrs, the illumation light is finally off.
Q: Is it ok? Does it happen to yours?

dosen't wake up
after the x1 charges to full battery, the device dosen't wake up on pressing the power button, this thing is new, almost few weeks, i don't understand, is a hardware problem or a rom problem... can anybody help me with this,
ps... the xperia illum lights dosen't turn off after charging, and charger disconnected they still blink

It's normal behaviour of the Xperia X1 to keep charging when the battery meter has reached 100 %. And it's also common for the charging process to take some time. I don't know exactly how long the process takes because I usually charge the battery during the night but charging an empty battery is certainly not accomplished in under an hour.
Your second problem could be a software issue. What rom is installed on your phone? Custom or stock? Have you tried a hardreset yet?

It happens to all X1. AFAIK, it's okay to disconnect the charger after X1 reach 100%, no need the blink to be stopped. The same thing is happened to my previous HTC too.

I don't know any Windows Mobile Phone that stops charging immediately when the battery meter has reached 100 %. One reason is that the meter only measures in 10 % steps. So when it reaches 100 % it might only be 96 %. To charge the battery completely you have to leave it connected until the leds stop indicating the charging process.

Okay guys, I got u people's meaning, yeah I remember that it was happened to my elder PDA too, O2 mini. Thank you people, to spend your time. Sorry bother you.

P9 won't charge after battery replacemnet

So like the title said i have replaced the battery in my P9, with an original battery. It has the same part number and all that. I have noticed that the phone won't charge the replacement battery, i have returned the new battery in warranty and revived another one. Same thing, the phone starts up as soon as you plug in any kind of power source to it , like a charger, but no charging notification. The notification light pulses in rare intervals (some thing of 10 secs or more) but it's not steadily on like when normally charging. And the most vexing thing is : if i replace the original battery it charges. Unfortunately the the original battery now has the bad habit of cutting out on me at random from anywhere 47% or bellow .... The phone is nearly 3 year old now.

Have you given the new batteries some time to charge? Maybe they were delivered to you fully discharged.

First one was on 85% the second on 60% or so. I kept the 1st one on charger for a whole weekend... Still nothing

Have you tried to callibrate the original battery (you say it suddenly drops if below 40%)?

Yes, I have allowed the battery to run down to 3% and the phone turning itself off. Then fully charged it while being off. So the original battery is just plain old, nearly 3y old. The problem is that the phone refuses to charge the new batteries regardless of original charge. Also it turns automatically on when you plug in a charger, not just showing the charge animation. That is not normal behavior.

I've done that after reading you'r message , but i have already done the steps not req root. And i'm not willing to root my phone.

P9 also not charging
Did you manage to find a resolution to this issues? I'm having the same problem with my P9. I changed my battery, and it now won't charge. It turns on ok, and everything seems to be working. When I plug in the charging cable, it makes the sound it usually does, the battery symbol flashes green but instantly turns white again. When the phone is off, plugging the cable in switches it on, but no charge. I've had two replacement batteries, both have the same issue. Also, the original battery is now doing the same. I'm wondering if I damaged something while removing the battery.

I think it's problem in charging IC or port.

Hi all
Had same issue with replacement battery
After replacement battery isn't charging. Problem is in bad connections
(probably from long shelf storage connectors got rusty)
Voltage was fine but temperature reading was way off (very low -2) and phone didn't charge battery
Problem is that there was no error message about battery temp.
After cleaning the contactors battery reading became normal and it started charging

Anybody ever had any solution to this problem? I have the same issue. Battery replaced - not taking any charge. If micro USB charger plugged in - the phone turns on. If it is already turned on plugging in the charger the screen flashes the % of the charge and nothing.
