[Q] HD2 bad battery?

I bought new HD2.
I have this phone for 4 days.
I think sth is wrong with my battery - 100%, I make a 4 min call, suddenly I have 96%. Another call - 10 min - 89%.
A tried many things, tricks mentioned here on the forum. Didnt help.
(HR, clean system without programs, took out micro sd cards - nothing changed).
Today I ve tried to charge it (from 2%) - I turned off the phone - wait 4 hours. Still amber light. But when I turn on the phone (still connected to a charger) light changed to green (and i saw 100% status battery on taksbar), then i turned off again, and green light changed again to a amber light.
Have you the same?
Or that means I have corrupted battery?
Ive been on many forums, and i see people saying - battery is for 1 or 2 days, and another group - battery for 8-10 hours.
Be grateful for your ansewers - I dont know what to do.

After 4 hours of charging the battery should be about full. But it why not charge it all night? If the phone is new you should charge it a longer for the first couple of times. And the battery could drain faster the first few times.
You didn't mention if you turned on Wifi, bluetooth, data connection, GPS, 100% screen brightness, heavy apps. All of them might drain your battery faster.

the longest i have personally experienced, and I am currently still opn this status, is that one single battery charge lasted me 4 days. While draining about 5-10% each day.
How tho? I simply dont know! to be honest, I somehow managed to screw up my today screen so I can have no htc sense on and sometimes nothing on.
anyway about the battery charging, I suggest you to read this.
dunno where I got it from and real or not, it might just help you
good luck

Thx for your answers.
But tell my about this indicator - green and amber lights.
I turns green only when I charge battery and phone is ON.
But when I charge battery while phone is off, then i can wait 3-4 ours it's still amber (but when I turn on phone suddenly it changes to green and it shows 100%).

The four hour charge - was that with the charger or USB computer charging?
I can do full charge in 1.5 hours from the charger and over 4 hours on the USB computer charging.

ok, it donest matter - usb or cable.
matters - phone ON or phone OFF.
When phone is on - turns green.
When off - it is all the time amber (red) - using USB or cable, doesnt matter. But when i turn on the phone it changes to green. when i turn off, it changes to amber again.

X2 Charging problem

So the phone was really low, at 6% this morning. SO I put it on the wall charger. I saw the icon come up that it was charging and then put the phone down.
A while later I went back to the phone and saw that although the charger was plugged in to the wall and also plugged into the phone, it was NOT charging.
Using the phone I went to my contacts to check a phone number and then it turned off, due to no charge.
I plug it into the wall charger, the USB connected to the computer, as well as the car charger and here is what happens:
The top and bottom of the phone blink red for about 1-3 minutes.
Without pressing anything on the phone it automatically turns itself on, I see the Sony Ericsson boot screen, the Windows boot screen then my SPB Mobil Shell screen for about a second and then it turns off again showing and the blinking red light for about 1-3 minutes and then it starts the process all over again.
I think that a setting for Backlight/Power management was changed. As setting similar to "Only charge with usb", or "only charge when connected with ActiveSync" or somthing like that.
The problem is that I turned off the Active sync on the phone in order to conserve battery power so that I could look up the phone number from my contacts. And after I did that the phone shut off and I cannot change it, because it will not charge.
I do not have a different, charged, battery to try and do not think that I can find one easily.
Any suggestions?

Now when I see that the phone is re-booting(I see the SE logo), I use the stylus to to soft reset. It is obvious that there is some type of charge happening before it re-boots, , otherwise it would not re-boot. SO my theory is that by doing a soft rest between restarts, the battery will gain more of a charge each time. And possibly have enough of a charge so that I can go into my settings and see the backlight/ power settings have been changed.

So I took a battery from my old SE 902 phone and rigged it to work with my X2.
It booted up just fine. I was able to get into the menu for power settings. Nothig was changed however I did check the box "do not charge when connected to the computer" backed out of that screen and then went back into the screen and unchecked the box.
I powered down the phone and the screen went to the default charging battery meter.
I then put the proper battery in the phone and it was still blinking red. I saw it blink green for a few seconds, then I felt it vibrate, and then I saw the green battery meter. But after a few seconds it went back to blinking red and I could not see the battery meter again.
This seems to be happening intermittenly. As of right now there is a green blinking light and I see a dimmed battery meter.
Hopefully it will be fine, we shall see.

So it was charging for a while and now has stopped. I see the battery meeter, but there is no green bar moving up. and the light has stopped blinking.
I unplugged the usb and I still see the battery meter with no green bar moving. Installed the back cover and plugged the usb back in.
Now it is back to the red blinking again. . . ? ? ? ? ?

I think that it is a battery issue.
CAn anyone suggest why a battery would all of a sudden stop working?

Just ordered a new battery. $70.00!!! Ouch!!!
It does come with a battery charger for use with a Mini USB, but still, $70.00 is a lot of money!!
I will update with the results after i charge it up.

I got the new battery and put it into the charger. As I mentioned in an earlier post the new battery came with a separate charger for use with a mini usb. At first I had problems. The charger would not charge the new battery. I was using a wall connected mini usb to power the charger. So I went to the computer and tried the mini usb from there. It still would not charge. So I took the battery out of the charger and put it into then phone and went back to the wall charger and it was charging. I could feel the phone vibrate and then saw the battery meter slowly fill with green and back to empty and then fill green again.
So I decided to do a few other chores around the house and went to check the charging status after about 10 minutes. I noticed that the phone was on!! I did not turn the phone on. No one else was in the house to turn it on. It was just on. Weird.
So I took the battery out of the phone and decided to try the new charger again with the computer mini USB. It WAS charging this time!! I charged the new battery on this charger using the computer mini USB until the red light(charging) turned green (finished charging) and then put it in the phone. It works fine.
I then decided to put the defective battery into this charger and it was actually charging!! I left it overnight and it was green this morning: identifying it as a full charge.
When the new battery is down to 10% or less I will take it out and put the defective battery in and see what happens.

So I put the original battery back in after the green light came on identifying a full charge on the accessory charger.
It showed 1% and a message came up identifying that "the battery is low, please charge asap", something like that.
So, in my unprofessional opinion , the original battery is toast.
The new battery worked great after its initial charge using the included accessory charger.
When I decided to charge it using the phone itself with the wall charger I noticed some really weird things happening.
First of all you should know that I downloaded and installed Spoon Charge. Look it up here on the forums, free and works great. It basically tells you what charge level you have, temperature of the battery, what voltage is coming in to charge it and also type of charge the battery is doing: trickle, fast, very fast and on battery.You can set it to read reading at specific time intervals: I have it set to read at every second.
I noticed that the charge kept bouncing between very fast and trickle. At one point it went to on battery, then to trickle then to on battery then to fast.
Ok. Weird. . . I thought to myself.
So I let it continue to charge overnight.
The next day I "tried" to use the phone. it was as slow as it was at it's factory installed settings before I did the memory card fix, accelerator settings, and other fixes that I forgot now have forgotten that I have installed.
At this point I decided to drain the battery as fast as I could by turning on WiFi, Bluetooth, and play a movie at the loudest volume possible. As soon as it reached 10% I took the battery out and charged it with the accessory charger. The next morning I saw that the indicator light was green showing full charge and installed the battery in the phone. It booted up and I immediately received a message that the battery was low, saw 1%.
Knowing that this was a BRAND NEW BATTERY, I turned off the phone and took the battery out and waited a few seconds until I put it back in and rebooted the phone.
This time it said 86% charge!!!!!!
WTF!!!!
So I tried to use the phone and it was as sluggish as before. After about 25 minutes it was starting to be a bit faster but nothing like it was before.
I am really confused now. Since I have a new battery I have ruled out that as a problem. So now is it the phone itself? Could it be the wall charger that is faulty?
Any other suggestions would be greatly appreciated.

Another update.
I put the original battery in the phone and now it works!!!! The old battery that would not charge now charges and works!!!
The phone is not the same. Still really slow, can't get it out of the "LOCKED" position when I want to answer a phone call. Opera is sliggish then fast then sluggish. Not what I had the phone at before all of this started. It actually WAS stable. It WAS useable. Now I want to throw it into the drink!!!!!!
Not sure what to think anymore.

well bro go into the system help of ur mobile press as i say
2ce the end button one time call button, 2ce the end button one time call button,one time end button and u will find the problem it is in the charging port the same issue with me

Battery Qustion???*

i just got the phone nad first charge i charged it whe ni got it and now its dead im charging it battery is very weak compared to nexus one i had.... but is it true that if u discharge it completley and then charge it completey and repeat 3-4 times battery gets good? i also heard over a little time that battery gets way better? any one can relate to this?

Sounds like you could benefit from re-calibrating your battery. It can be done manually through recovery by resetting battery stats, or easily through an app like this one (you must be rooted).

how u do it without rooted and i heard discharging 3 times and fully charging works? any update on that

There's lots of different "methods" floating around about how to calibrate your battery, many of which actually don't make much sense. The ones that do make sense to me involve deleting the batterystats.bin file. That app TeeJay3800 linked to pretty much does just that. For rooted devices, all the ClockworkMod recoveries have an option to delete battery stats in the Advanced menu.
I think this file is located somewhere in /data but I don't know off the top of my head. I also don't know if root is required to delete this file. Maybe try finding it with Terminal Emulator and attempt to delete it. If that doesnt work, then you'll probably have to root the device (or maybe just temproot it).

yea i did it yesturday nad today its still bad about to attept 3rd charge and im waiting till it dies it went from 39% to 19% within an hour wtf is this??? im waitign till ti dies then recharge to fully

i also did this wthich is good but will it mess anything up if the phone is brand new and is charging fine
Connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
Disconnect the phone from the charger, and power it off.
Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
Disconnect the phone from the charger and power it on.
Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.
Disconnect the phone, power it on, and use it. You need to use this sequence only once.

This is "bump charging" and all it does is try to fill up your battery as much as possible. It's like topping off at the gas station. It won't do much as far as battery calibration. You may see a minor improvement in battery life after a bump charge, but you'll have to do it each time you charge.
Keep in mind that battery life is dependent on many factors, including your usage pattern. Improving battery life is a matter of being mindful and selective about what connections you leave open (bluetooth, GPS, WiFi, account sync) and what apps you let run. Screen usage plays a role as well. Network signal strength also plays a part, but that's not something you can control. Don't use taskillers, they cause more problems than they solve.
I'm assuming you're still on the stock ROM. If that's the case, you should be aware that there's lots of extra stuff on there that runs in the background to support the HTC Sense overlay. The biggest improvement in battery for me was (a) flashing a custom ROM without all that junk on it and (b) flashing a custom kernel which both underclocks the CPU and uses lower voltage settings.
If after all these considerations you still think your battery is borked, head over to a T-Mobile store. They may give just you a new one, otherwise it'll probably cost you not very much.

Streak 5 dead, what now?

Hello! i have problem with my streak 5, few days ago battery drained out and phone shut down.
i connected ti a charger but nothing happen, no reaction on phone so i left it on charge all night.
Still no response, no picture on the screen, no backlight, no LED, completely dead.
I can get reaction only when i enter in fastboot mode (holding power+camera)
IN this mode touch screen not working, computer recognize device and i can do flash and i do it successfuly but i still cant turn on my phone.
What can be a problem, I tried everything with no luck, also i have not found anyone with same problem
I have 2.2 official, no root.

Try changing the battery. The one you have could be defective, or else there is an issue with the charging circuit.

I measured with instrument 3,67V, connected od 1 and 4. And few other combination i get from 3,30 to max 3,67V.
This seem to be ok, regardless of that you think might be the battery?

Never let the battery drain that much becase now the battery doens't have enough power to start the charging... you should charge the battery manual with some wires on (+) and (-) from a old phone charger be carefull with the voltage(V) and the ampers(A) not to brake the battery, 20 or 30 min should be enough, or you should buy one of this Universal charger. Then place the battery in the phone and it should work ok .

This morning I optimistically tried to turn on a phone and it was successful
battery Indicator showing 7% so i connected to charger, now is normaly charging, everything is working normally...
I do not understand, what could happen? i few times drained battery to 0% but still able to charge, maybe battery is problem, but again, turned on after 3 days

Don't worry the battery is ok the problem is not to empty it again to 0%, at 5% 7% close the phone if you don't have a charger to charge it. This method applies to every phone and battery. It's not a good thing to fully discharge.

Now is fully charged and power is 4,07V.
So obviously battery caused this problem.
I think, good info for all who suspect on battery, 4,07 V is power you need to have on fully charged battery.
With 3,6V you cant event turn on the phone.
Thank you for suggestions

Last month i faced the same issue and this mostly happens when flashing/changing rom or kernel or could also happen when you dont charge your phone above 90℅. The battery stats file needs to be refreshed. Charge your phone to 100℅ and dont unplug it. When it reach 100℅, unplug and plug the power cord in and out a few times (wait a few minutes before unplug again) to make sure it reach 100℅. If everything goes well it will show the correct battery levels again.

Battery Calibration Problem
No need to worry man...this happened with me too..its just a battery calibration problem
If non-rooted
1.Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent plug the charger back in until it says 100 percent on screen.
7. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
9. Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.
If rooted then just follow these steps:
1. Discharge your phone fully until it turns itself off.
2. Turn it on and let it turn off again.
3. Fully Charge the Switched off phone.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in and continue charging until it says 100 percent on the screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7. You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
8. Now, install the Battery Calibration app by IMobS Ltd(Available On PlayStore) and, before you launch it, make sure your battery is at 100 percent again, then restart.
9. Immediately launch the app and Re calibrate your battery.
10. Once you've calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
11. Fully charge the battery one more time without interruption while it's switched off, and the Android system's battery percentage will be reset.

IF above methods doesn't work. Take backup of important files and Reinstall rom

there is a xposwd mod called disablecriticalbatteryshutdown.maybe it will help..
Peace to all

my phone switched itself off once from 60% when I was testing the coffee kernel. I'm not saying the kernel caused it but I reflashed to optimus and never had similar issue.
