Final solution: power-off while battery indicator at XX% 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)?

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.

Charging stuck at 70%,PLS HELP

Guys pls help..I have this problem,that when I'm charging my trinity,it couldn't reach 100% of charging (full charge) instead was stuck to 70%.eventhough i charge it overnight.I'm thinking if it is a battery prob or the charger. i am using the originally supplied charger & battery.
Thanks in advance...

Have you tried powering the unit off, removing the battery for, say, 15 seconds, then refitting it and rebooting?... Check the battery level after reboot?... Then retry charging again?...
Maybe a full discharge might help "reset" the above problem too?...
I'm not sure, but I think the Trinity battery management is quite dependant on so called "coulomb counting" and I reckon sometimes it goes a bit wrong.

i tried all your suggestion bro,after rebooting,the battery meter increased 10%,tried to recharge,but still can't reach full.i tried to turn off my device then charge it,this time it goes upto 90%.it's a good sign but,charging while my phone is turned on is better right?i have no computer around,maybe i'll try to charge thru USB later..if it went ok,maybe i'll buy a new charger..thanx loopyloo for that sound advice..

Try battery callibration procedure!

The actual standalone charger (if that's what you're referring to) has no intelligence in it to speak of. Battery charge monitoring/status will be an integral function to the phone itself using dedicated h/w.
Something's not quite right with your kit somehow. Maybe the battery has gone a bit wrong (could be replaced - how much use has it had?)... Rather that than the phone itself, in which case it'll need repair.
You can try tnyynt's suggestion of Battery Calibration. Basically this requires you to totally discharge the battery (I suggest thru normal use of your phone!) then when it shuts down "cos battery is flat" reboot the phone into its bootloader screen (power down, then press and hold Power & Camera buttons until Tri-colour screen is displayed)... Then just leave the phone until it powers off of its own accord.
This may take a few hours (I did mine recently and it took @4hrs!) but the battery should be as discharged as its possible to get by that point...
And if you're lucky, it might just sort your problem out when you next recharge!
Good luck dude!!!

thanx again LoopyLoo,you made this procedure (battery callibration) clear to me,on how to do it.will try this procedure and will report asap the result.hope it works (fingers crossed),and hope it's not an internal phone prob.
Thanx Bro!!:>

Let me know how you get on.
I'm a little baffled as to why you have problems with your friends charge too but not USB???...

battery callibration not worked...
I'm sorry to report that after 3 times of trying the battery callibration method,my trinity still doesn't reach its 100% capacity of charging thru the standalone charger..but mysteriously charge a 100% with USB charging..I'm still not really sure why this happened..maybe will try to see a mobile technician for PPC..anyways,thanx for all your suggestion..will report ASAP after going to a service center..

Sign of bad battery?

Have a TMOUS purchased in May. Latest stock rom/radio. When the battery is super low it goes through the process of shutting down - but when I plug it into the charger the phone will boot instead of staying shut down and charge. Will attempt to boot then go into Sense then shut down again and do the same process all over again. The only way to stop it is to quickly power down and it will stay down and charge. In any of the situations the phone appears to be charging.
Is this a problem with the ROM/Hardware or is something going on with the battery? Have an 8GB SD card with Android (no boot loader) and thats pretty much it.
Any advice would be appreciated.

I doubt that your battery is gone bad, but there are chances, try to condition your battery

Its just a little strange that the when the supposedly dead phone is plugged into a charger it boots up without pressing the power button. Don't think thats normal. Also when plugged into a charger when the battery is "dead" or near dead it should boot up and charge. This one doesn't - it boots - shows an LED charge light and then powers down and reboots. For some reason the battery with such a low charge can't power the phone and charge at the same time.
Will attempt to do a hard reset - maybe HD2 Tweak or something else did something to the registry and try it again. Since its under warranty will request another battery and take it from there. Don't think anything is wrong with the phone's hardware because it functions flawlessly.

If the battery drains and shuts off because it's out of juice, it WILL turn back on as soon as you plug it in, but it shouldn't keep rebooting after that...
Also if it's just shutting down on you in Android without warning when it's low, you need to condition your battery in Android so that it has the correct batterystats info.

No something is wrong. Ran it out of juice in WM this afternoon. Got the error message let it go. Went down and shut off. Plugged it into a car charger USB/cig adapter. Powered up go to tmobile screen/radio code then animation - rebooted did the same thing without touching it a few times then shut off - light led for charging did not appear.
Pulled battery - when charger disconnected - plugged charger - red light no reboot. Tried it again - same results with a hitch - it froze when it was charging - accessed internet explorer then it did a hard freeze - had to press reset button.
Don't know whats going on at this point - it shouldn't have done the freeze. So I'm going to experiement - pull the SD card (has Android on it) and try it again without the card. Try another card, try another charger and see - if I get the same results its either the phone or battery. When I have a charge greater than 5% there are never any problems. Only when battery level 0-1%.

Your battery pins aren't bent are they? (The little guys on the phone side that smash down when you insert the battery)

No, they are fine. I did call T-Mobile this afternoon and spoke to a level 2 tech - they think the battery is bad. Under warranty and have to call HTC tomorrow morning.
The phone does charge and does get to 100%. Drain in Windows seems fine and uniform but it does drop quickly once I get to about 20%.
Because of the reboot issue I think one of the cells is bad. Doesn't seem to want to trickle charge when the battery is that low. Tries to reboot - but can't get enough juice to sustain itself. Should just bypass through the battery as its charging. Either its the battery or somehow the charging circuitry is bad - who knows - with a new battery if it still does it then is the phone's hardware.
Will stop using Android for a while until this gets worked out - although I prefer the browser over WM 6.5.

Def sounds like a battery issue then, if the pins aren't bent because that is the biggest symptom of bent pins.

Broken Leo, Broken Battery or a software problem?

Exactly one week ago I got my new Leo (standard European version). Well it wasn't exactly new but a display unit that was probably running 24/7 connected to the charger in the store for more than a year.
When I woke up this morning I realized that the charging indicator LED was still orange and not green although the phone was charging all night. When I checked the battery indicator it said 54% or sthg like that (that's what it was when I plugged it to the charger in the evening). After I powered the device off and powered it on again the battery indicator was suddenly at 100%.
So somehow it did actually charge but somehow the software "thought" it didn't.
I think that maybe constantly running on the charger in the store for more than a year might have damaged the charing circuitry somehow. But is that circuity in the Leo or is it built into the battery pack itself?
If it's in the battery pack I could just buy a new one for a few bucks but if it's in the phone itself I would have to send it in to replacement after just one week
Or do you think that this is just a software problem?
Thanks

It could be battery calibration. To re-calibrate do the following:
Charge phone to 100%, then wipe battery stats, let phone discharge til it goes off (battery has to be empty), then charge again to 100%.
Hope that'll do it, if that doesn't work then try a new battery unit.

Wipe the battery stats? Isn't that for Android? The OP did not say he was using Android. If you are speaking of WM, where is this file located?

Thx very much for your help but yeah I'm using a stock Windows Mobile 6.5 ROM

I would switch out the battery first.
To answer your first question, there is circuitry in both the phone and the battery.
Also, go ahead and check the phone battery contacts for bent pins.

I figured that it was most likely just a problem of the alarm clock program "G-Alarm" which apparently has some compatibility issues with the Leo.
I went for a different alarm clock program (SPB Time) and hope that the problem is gone now.
Thanks for your help!

[SOLVED] Nexus 4 dying at around 30% battery

Hey guys,
I noticed this yesterday my Nexus 4 (running PA 3.6, franco milestone 1) shut down at 30% charge. I went home and charged it (it showed 0 when I started charging it) to 100% continuously.
Today too the phone shut down when it was around 32-31% and now charging has again started from 0%.
What could be the issue?
I have tried the battery calibration app even though I know it does nothing.
Any ideas?

I have been flashing nightlies merrily on the Nexus4, never had to recalibrate the battery, though it sounds like your does need that. (I had a Desire HD before this, and it was very sensitive to errors in battery calibration)
How about if you charge the phone fully then either reflash the ROM or flash a nandroid backup you've made? Either of those options will overwrite the battery stats file - if that's the problem.
It could be that the chip in the battery is malfunctioning, ie a new battery could be needed, but that sounds much less likely

Okay I'll try reflashing the ROM when I'm at a 100%, I know deleting the batterystats.bin file doesn't do anything but I did that anyways yesterday, but it seems it didn't fix the calibration issue.

Hi, @paul c, I would like to inform you that my phone's discharging just fine (charged it to a 100% last night and it's currently at 48%, I didn't reflash my ROM but I did reboot it once. I also haven't charged it since then)
Could you tell me what's the minimum and maximum battery voltage? I am guessing that the max voltage is around 4200mV but what's the minimum? Also, can we calculate the REAL battery %age from the voltage that is displayed by apps like DashClock? If we can do that could you tell me how/what formula we use to do that?
I know I'm asking a lot of questions and I would really appreciate any help here !

Hi,
I was inspecting the battery's voltage/charge the entire day today and I realized that at around 36% the voltage went around 3000mV (3100mV, Nexus 4's battery is rated at 3800mV and it maxes at around 4200mV). After that when I plugged it back in and turned it on it started charging from 0%.
I think the battery is at fault.
Is there any fix for this which does not involve replacing the battery?
Thanks!

Unfortunately this didn't work for me. I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

When you open the back case did you notice if the battery looks bigger/inflated? Maybe you should replace the battery.

Okay, I got my battery replaced, drained it to 0% (after a full charge) and going to charge it completely by the travel adapter that I purchased from the service center.
Attached are the pics of my old battery, I don't know if you can see it but it's swollen. If I recall I used a nexus s' charging cable to charge the phone from a computer and it was charging like AC (my kernel usb fast charge was OFF) and it also never detected my phone in the explorer (Windows)
My problem's solved now, it was a battery issue for me. I upgraded to PA 4.3 in the process by the way
So I guess I'll stick to my regular micro USB cable and charge via the travel adapter whenever possible, thank you everyone for your inputs!

Might as well replace it while you're at it. It's $20 on eBay OEM.
