Everything was just fine until yesterday when i realized the batterty's built-in monitor wasn't reading a real batt stat. I was sure I was running out of charge and the divice was still saying there was 50% left. I did a soft reset and my atom didn't boot. I took the battery off and waited more than 3 hours, put it back and couldn't boot. I haven't ever done anything to my mobile. No register tweacks, fisical hits or rom upgrades. I searched the web and found a procedure to get it back. Reset+camera choose 1 option and there you go with your device booting at last. I did so but when it ended whith the system loading proces it sent a notification saying that the battery was exhausted and it went off. Again it couldn't boot in a normal way even with the ac adaptor plugged in. I made sure the battery was fully charged. I did a bootloader again (reseat+camera) with the usb connected and i could get it back again but showing 0% battery indicator and would turn off as soon as i unpluged it. I tested the battery with a multimeter and even when it was fully charged i tried to recharge it until green light then i turned it on and the batt monitor was 100%. I could unpluged the usb and everything was fine. It didn't turn off but the indicator got stock in 100%. After an hour or so of normal use i was sure the battery was 90% or less while it was still indicating 100% of charge. I did a soft reset and couldn't boot again. I think the device knows when the battery is 100% charged but when it is less tha 100% and i do a soft or cold reseat the mobile thinks the battery is 0% and won't boot.
Yes, I have ugraded to ROM Xda-Atom-Exec-ENG-20060721-MOT0822 to see if this fixes it but now i have a rom-upgraded aton exec with the same fatal error.
I am at work rigth now and hopping my atom doesn't need a soft reset because if so i need to plug it in in order to be able to do a reseat+camera and wait some minutes until green ligth shows up. My atom knows 0% or 100% of battery charge but no numbers in beetwin.
Any ideas?
did you charge the battery for 8 hours on first use, continuing to discharge battery completely first three charges?
This is crucial for battery performance I now get at least three days of moderate usage and at least 7 days in standby, my advice is go buy a new battery follow the instruction manual completely, failing any changes (be sure to buy battery from somewhere you can get refunded) return the battery. Try also reflashing using bootloader mode, not using the SD card!
The last time i used bootloader was after hard reset a no card inside then i performed the last ROM upgrede available from O2. It seems to be a hardware problem more than a software problem as i thought at the begining.
I hope you are rigth, i guess the device gets charge information from the battery and the battery is telling it when it is 100% and 0% when it is under 100% and after a soft or cold reset. I am going to drain the battery all the way down and recharge it up to green light to see what happens. By the way i did not charge the battery 8 hrs when new.
Where do you think my atom is geting the batt charge information? From one of its inside sensors or from batt circuits?
Thaks for your advice.
I mean reflash using bootloader mode, ie. enter bootloader then plug in USB and run DSUU installer from your PC. Its hard to say where the fault lies, some Atom's had power management issues and O2 are fully aware of it, if yours is still under warranty I suggest sending it to a service center but be prepared to be without it for at least a month! (should change their name to SLOW2) and also be prepared to have it returned to you only to find they havent done a damn thing!
Its a bad battery, same thing happened to me. Just return it for a new one, the material is moulded with the smart chip inside there is no way to fix it.
Now my battery is beetwin 100% and 85%. I have searched other forums and i found out it is definitly a battery issue. It has been more than 6 months since i bougth my Atom so i have no more battery garanty. I thing i am going to wait before i buy a new one in orther to get the most of it since it still last more than 2 days.
Thanks for the information.
when a battery xp-02 (for atom family) is sometime stop at certain percentage, says 72% for long time, i do a soft reset and it drops to says 40%, is it a symptom of bad battery? or it is a ROM problem?

I started this thread because I lost lots of time to find the answer to my problem scattered over many, many threads. I hope this posting can save a lot of time for others.
The problem
The HTC Universal suffers from the problem that the device turns off while the battery indicator still shows juice left.
The cause
It's the battery or the way how the device interacts with the battery. It can have something to do with ROM upgrading while the battery is not at 100%.
Solution 1: Buy new battery
A lot of people will immediately tell you to buy another battery. That's a solution. Batteries are not that expensive anymore. See Ebay for example.
Solution 2: Recalibrate the battery
For me it wasn't a solution (it was a new device with a brand new battery! And yes, I upgraded to WM6 immediately after purchase)
Source: the greatest part of the solution for me was provided here by Jwrightmcps.
1. Charge the battery overnight with the supplied poweradapter, not with the USB cable, then:
2. Drain the battery without SD-card, powersaving off and backlight on full, then:
3. At some level, the device will turn off. Switch it on and go to the bootloader by backlight+power+reset button and drain the battery until it's really empty, then:
4. Charge the battery again with the supplied poweradapter
*** WARNING AT YOUR OWN RISK ***
You can also try to put your battery in the freezer overnight (wrap it in plastic) to drain it, as I once did with a laptop battery. Let it get back to room temperature before you insert it back into your device.
*** WARNING AT YOUR OWN RISK ***
Prevention
Always drain your battery before you charge it.
Charge the battery with the power adapter not with the USB cable or car adapter
My story
I bought the device new in store and charged it in the car when driving home (one hour). After that I hooked up the device to my PC and upgraded to WM6. In the evening, when the battery was arround 40% it shut down... Never got a battery low warning.
(please make this sticky)
Effects of Bootloader mode?
A simple (silly?) question: if I enter Bootloader Mode do I loose all my data? Can I enter bootloader mode and just restart with no more effects than a soft reset?
When to exit bootloader-mode (i.e. reboot the device normally)? Before charging (before step #4) or after it is fully charged (after step #4)?
Cheers,

Well I don't want to invest in my universal as i'm changing it to another one, so I'd better fix my battery. I tried to do like this:
- discharge battery to 40% (device shut down)
- connected the + and - to a battery-powered speaker system and played music some time. This could discharge it more, what do you think about it? Well I can't say from my experience because I must wait for my device to discharge now

The bootloader mode is used in this example to drain the battery. The bootloader is 'exited' when the battery is empty...
Draining the battery in the bootloader mode will take long, because backlight is not enabled.

No, you don't will loose your date.
Yes, you can enter the bootloader and restart with no more effects than a soft reset.

That is also a nice way to drain the battery. Be carefull that you don't shortcircuit the battery.
doesn't work for me, seem it is a software wm6 reason, so probably there is one solution:
ROLLBACK TO WM5
maybe try to change another part of rom? update bootloader? i don't know... i prefer wm6 over wm5 but this gives me no choice...

(with full credits to user888 and JWright, of course)
when i had this problem, i just bought a fat battery... and followed the prevention steps. I only charge when my battery warning notification appears (less than 10%) and I dont use the usb cable anymore. When I recall why I got the problem with the previous bat, i realize it was because i had been using wm5torage a lot which required plugging usb cable. So now, when I need to sync my phone, I just use my old bat. My new bat has never given me problems (had it for 6 months now) and Im happy with it (although it streeetched my case a bit).
Just a few question before I do all the steps:
1. why we should charge it overnight on 1st step? can we stop charging after greenlight?
2. why drain batt without SD card? Can we drain it with SD inserted?
3. after on bootloader mode, it's only it? just leave it like that untill batt really empty itself?
thanx for this solution.
When I entered bootloader mode at 50% battery remaining it turns off after a short while. I connected the battery to a small motor to drain it but after a short while that too stops. When I checked the battery with volt meter it still showed 45-50% charge. What should I do to drain it?

Same with me. 2 times bootlader mode, just luck on 25% left before really off. Never got drain until 0%.
Connect it to a Voltmeter and lavce it connected until the voltmeter read 0.0volts. But be warned this might take a WHOLE DAY OR TWO. Has anyone tried the freezer method? does it really drain the battery?
I'm going to try the freezer method.
Report here later

Tried freezer initially for 5 minutes and then for whole hour no harm came to battery but no gain as well! Charge didn't drop even one percent. Isn't there some fast way? Waiting with voltmeter for a couple of days is tiresome.
And now the agony has increased even though battery is fully charged if I remove the charger my device turns off. Trouble is that original batteries aren't available here in Pakistan, Rawalpindi to be precise. Now what to do?
Freezer method
I tried the freezer method for one night.
Next morning I took out the battery and let it come to roomtemp.
Took a long time charging (2,5 hours), but no result.
My device switch off randomly some time at 95% some time 50% etc.
i am using jw wm6.

I am not sure if this happened to anyone but I heard it did by a friend.
I use IMATE JAMIN version of HTC Prophet, my battery was in my device for a longer time without much of use. Lately, I was using it rarely for WLAN, it was running fine. Suddenly for the past 4 days it was turning off automatically ( even though the battery was 50 %) as soon as the device is boots to windows mobile
And then the period reduced to boot screen and auto shut down. And today, it dont start at all
I tried recharging, I dont see even its charging, not from USB or Direct.
Would appreciate if someone suggest something, before my handset service center ripp me off (coz my warranty period is over)
Please help by suggesting something.
I am not sure your case is same as mine or not. I tried to play my Touch b4 and made my battery totally flat. Than I couldn't recharge the battery by the phone. What you have to do is recharge your battery externally not by the phone. Because if the battery is totally flat, you can't use the phone to recharge your battery. After got some power back to your battery, you could use your phone to recharge the battery again.
The hard part is do you have anything can recharge your battery externally. I did so I had no problem. Good luck.
BTW if you really have nothing to recharge your battery externally, you can try to serial connect 4 AA battery and than attach the positive to your cell phone battery positive by a small wire and negative to your cell phone battery negative for about 15 mins, if not enough try another 15 mins. Should work.
Good Luck
Hi, I have a problem when charging and the phone is off. Few weeks later everything was ok - by which I mean that after few hours the phone signalised full battery by showing 5 full bars. Now I can leave the phone on charger even 12 hours but the fifth bar still blinks as if it was not charged. When online, everything goes fine: phone saying "charging" for some time, then "charged".
I`ve tried many ROMs since december and I believe its somehow related, but dont know how. I even tried formatting everything including sdcard in clockwork and then installing a clean stock ics rom but no change ...
Im afraid of breaking the battery somehow. With my second battery the phone acts normally - first "charging, then it states that battery is full. I found out that when I enter my spare battery into the phone and then give back the original one, its able to tell me "battery full" ... but not without this "swap" ... Im afraid of my battery be charged all the time - and damaged ...
NOTE: I want ti highlight that this problem happens only when the phone is OFF and I dont speak about the problem when phone was unable to reach 100%. This is different.
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

Not everything my friend
Just charge the battery for some HOURS or over the night. All the described symptoms indicate a low battery to me.
cheers
UPDATE:
Just managed to unlock a bootloader in that short period of time i can get to fastboot. But still no change, phone wont stay in fastboot.

Well, i actaully tried to leave it plugged over night. But i think it stops charging right after the red light dissapears, which happens after 15mins or so after plugging. Btw, i mentioned earlier that battery shows 3.7V when measured with multimeter, so the battery doesn't seem to be the culprit... or does it...?

your battery is drained below safe line....to 0%. They warn you NOT to update it with less than 60% battery FOR A REASON!!
Friends case she managed to charge ger asus 7 memopad with non-removable bat to 60% after 8 HOURS, because of a bloatware wakelock drainage to 0% after a factory reset....
If that doesn't work you have to either recharge the battery manually (something like car batteries, you have to unsolder the battery connector because the battery doesnt have 2 gold squares that touch the gold pins like the removable ones, or get a new battery.
Li-Po batteries should never be discharged to 0%, and can make problems if they are not removable (Nexus 4)

I did manage to charge it manually with two small wires and an old Nokia charger, when checking battery with multimeter after a few minutes of charging seems to increase voltage. But i guess if the chip on battery is fried there is nothing more i can do.
I will try to leave the phone on charger all night once again, see if that makes a difference, and update if anything changes.
take off the back, disconnect the battery connector wire and connect it again, put it on charger and see if things change
UPDATE:
Leaving it to charge overnight didn't have any effect. Any other suggestions than changing a battery?
Nah, sorry, but i am out of ideas. You basically tried it all :/

I know there is a lot of threads about bricked N4's, and i can assure you that I have viewed each and every one of them, but i still can't resolve my broblem.
This whole brick situation happened after trying to update to Android 4.3 OTA update, the phone didn't complete the process and turned off, where red light of death happened.
So the scenario goes like this:
If i hold POWER button for ~30s when phone is off charger i only get a Google logo for 2 sec, and phone instantly restarts
Holding PWR+VOL-DOWN buttons when phone is off charger doesn't do anything
Plugging phone to charge (socket or PC) results in solid red light
Holding PWR+VOL-DOWN or PWR+VOL-DOWN+VOL-UP for ~15s makes the red light blink at a steady rate
While continuing to hold the respective buttons and pluging the charger off, and on again gets me to bootloader or download mode (depending on button combo) for ~2s and phone restarts.
I tried removing and inserting the battery 3 times. One time i got blinking red light when plugged the charger in. Second time i got solid red light and third time got solid red light again
I tried charging the battery directly for 15 minutes with old Nokia charger, and it resulted in something different(when i assembled the phone and tried to turn it on with PWR+VOL-DOWN buttons when charger was plugged off, i got to bootloader for 2seconds before phone restarted, i tried to boot second time and the same thing happened, but when i tried it third time i got nothing, just like before) so this was the first time i got into bootloader while not charging a phone.
*My PC seems to pick up the phone for a brief moment when it is in bootloader and starts installing the drivers. Drivers gets installed when i'm in download mode for that brief moment too.
**Phone doesn't get to the white or red battery icon while plugged to charge.
***Solid red light dissapears after charging for ~10mins, but phone won't do anything.
****When measured with a multimeter battery shows 3.7V
I hope someone will be able to help me with this, as it is frustrating as f*ck. I don't have a working warranty, so fixing the N4 isn't an option, and where i live phone repair prices are over the roof (ex. motherboard change for N4 costs ~270$ ).

I had the same problem. Kept it on the charger for a whole day and still only the Red Light.
Took it to a local shop and they said there is a short circuit in the antenna
Took it to the LG Service center and they said my motherboard is gone.
Both were costing a bomb to repair and still there was no guarantee.
IMHO, get a new phone.
Sorry
Have you tried charging it with a wireless charging pad? I got mine to boot after I did that. Your battery is drained and it doesn't have enough juice to charge itself.

Don't fall for the motherboard dead trick. Just a way to steal your money.... change the battery and never let it go to 1%
