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.

[Q] Is My Battery Dead?

So i woke up this morning and i forgot to charge my HD2, i had just rooted it a few days ago running smoothly on Core Droid. but when i tried to charge it, it didnt . no light was showing. before i had this incident the battery would run out quickly. When i try to plug it in to the charger nothing happens, and a few times it would shwo the boot screen then suddently shut down and now that doesnt happen anymore. Do i have to get a new battery?

Running Android may mean that your phone might not shut down before the battery protection circuit activates, to prevent destruction of the cell.
Once this happens the standard charger may not be able to charge this battery, although I have read that removing the battery from the phone for a couple of hours and trying again might work - do some searching on xda.
If you have access to other micro-usb chargers then give them all a go, one might work - or you may have to replace the battery.

Also try removing the battery whist it plugged into the charger then leave it as advised above

Good idea. After this you have to charge the phone for 100% before turning it on again (just leave it overnight)
Then turn it on, let it drain completely until it dies.
This way you have re-calibrated the battery and you might get better battery life.
Apart from that, you can try the one-in-a-million power saving tips.

[Q] X8 Battery Charging Problem

Today morning, I turn on my phone and I saw the battery is 80%, I put it in my bag. After 1h, I take my phone out and I found that my phone was very very HOT, and the battery went down to 10%! (normally my phone just drop 1-2% in idle mode)
After that, I pull out the battery and put it in agn. (I guess the phone turned on automatically, but I dint noticed bout it) After few hour, I tried to turn on my phone, and the LED showing red colour and keep blinking..I couldnt turn on my phone.
Now, I cannot recharge it when the phone is off, the LED din't blinking anymore.
I have tried to recharge my phone with charger, but it failed..I have tried to connect it to the pc too ..but it failed as well..
Anyway to fix this problem? Thanks.
Sorry for my bad english..

try get new battery maybe

I had a very similiar problem. My phone had been discharging battery in 3 hours from 100% to 1%. Once, the battery discharged completely and I wasn't able to recharge it, so I decided to buy a second battery. In my case it didn't help - the other battery was discharging exactly like the original one.
As I had a 2-year warranty, I returned my phone to the shop and guess what?
They replaced a mainboard in my phone (for free of course). Now everything is ok.

You try connect your phone to charger and charge more. Sometimes if your battery is recharged may not be detected for 5-30 minutes

Battery problem HD7

Hello everyone ....
I have a problem with charging the battery on my HD7...
When I leave the phone on the charger overnight ... the morning shines green light 100% battery, but after a few minutes show a lower value ... eg 90%. During the day, the battery drain is normal.
When the phone on the charger during the day and when the battery is charged (quickly turns off the charger) ... there is no effect of the rapid discharge of the battery. The battery is drained properly.
I concluded that the charger charges the battery to 100%, and then turns off. The phone starts to use battery the rest of the night. The phone is still on the charger. I think that is not normal behavior of the phone. My Trophy has not worked in this way
I use Nextgen 2.0 rom. and battery status v4.1.0
I wonder, the battery is bad or the software or something else.
thank you

No need, look at the bottom of his post - he fixed the problem with a new charger.

I had similar problem, changed to new one.

when u leave the phone on the charger overnight, what happens is that th ephone fully charges. to 100 % and then the charger shuts off. but the phone runs on fthe battery especially if u have the radios or wifi on but the indicator thinks that its still on the charger ...but the wifi radios ect is using the power
when u unplug the phone, the battery drains down to actual level aka rapid draining

I think battery or charger should be the problem but probably battery. pretty cheap on ebay

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.
