Tilt battery voltage not sensed by phone?

I have this strange problem that just cropped up. After a full recharge the other day the battery showed normal draining. When I tried to recharge it wouldn't; neither from the wall charger or usb by computer. So the battery showed steady drain unless charging, but never got more charge. Finally when turning on the phone on battery alone it shows 1% charge, and there's nothing I can do about it, the phone will turn itself off.
Diagnostics: I measured the battery voltage and it is ~4.2 volts. This seems like a full battery yet the phone doesn't see it.
I measured the voltage at the battery terminals in the phone while hooked up to charger which was ~4.2 volts. So it seems the battery is being charged.
Why is the phone not seeing the battery charge? Is the battery dead even though it measures 4.2v?
I did run the gps before this happened using gps tool, bit I think I turned it all off. Anyway more than one soft reset didn't help.
Thanks,

No real answer here but perhaps something to try:
I am dealing with another member who has a similar problem.
http://forum.xda-developers.com/showthread.php?t=377675&page=2 From post 17 onward.
With battery in, the orange charge light comes on and all seems normal. However with a few seconds of turning on the message that the main battery is critcally low comes up and the phone turns off. He has tried another battery with the same result. This happens even with the charger connected.
(EDIT: I have now read that his has - for no obvious reason started to work ok - Now even more convinced it's a charging circuit lock-up issue - given time and possibly a bit of battery fiddling and it comes good in the end - see No 2 below)
Now I'm wondering whether this could be one of two things:
1.
A hardware fault - possibly in the charging circuit or more crudely one of the battery circuit board connectors is not connecting.
OR
2.
The circuit that controls charging has to put it crudely become "stuck" in a similar fashion to those who get the RLOD red LED showing when they connect the charger. A commonly accepted trick for overcoming the RLOD is to connect the charger and wriggle the battery on and off the four contact pins. This presumably has the effect of forcing the charging circuit to re-set itself. I just wonder whether it might have the same effect in your situation.
Mike

hey.. that would be me with the similar issue.
i just tried a couple more things.. check out the thread.

More info.
Battery in and out holding the power button had no effect. Phone runs fine while plugged in. Plug it in and after 5 seconds the amber LED turns to red. While plugged in the red led will flash amber every so often.
I measured the battery voltage as I turned the phone on, it dropped to ~ 3.98v, then came back to 4.1v as the phone turned itself off. It gets all the way to my Today screen before going off. Just sitting in the phone with it off is 4.1v. Hook up the charger and the battery sees 4.18 and rising after 20 seconds. These are direct measurements at the battery terminals while in the phone.
So this looks like a software issue to me. The phone is charging the battery and there is plenty of power to run the phone, the phone somehow doesn't see it that way. It sees a dead battery. Well, I guess it could be a voltage sensor gone bad , somewhere somehow. Next step is to hard reset and see if it makes any difference.
edit: While plugged in and the screen on, the led stays amber. When the screen goes off(set for 2 minutes) the led turns red. Screen back on, led amber. I just set the screen not to go off while plugged in(charging), we'll see. The power is showing 7% now and says charging, too early to tell if it's rising or not.
edit 2: It stayed on the charger for several hours and never moved past 7%. Tried a hard reset with no luck. Next step is to send it to a repair shop(I bought it used) and hopefully spend only the $95-$125 they quoted.
Will keep you apprised.

Att Tilt Power/Battery Issues.
I am having somewhat similar issues with my Tilt, with the power/battery problems as described previously. I woke up this morning, and attempted to turn my phone on, and it wouldnt come on at all. I then plugged it into the ac adapter, and the LED comes on, and goes green. I waited a few moments, then powered the phone on to take a look at the battery life, and the phone boots up, then reboots during the splash screen. After it reboots itself, I check the battery indicator and it shows 1%. If I exit the battery screen, and re-enter it, it will say 100%. Now, as soon as I remove the charger from the system, it automatically powers down. I played with it for about 15 minutes, but needed to head to work, so I took the phone with me, and attempted to use my car charger. Same problem. Now, I figured, fine, I'll see how it behaves while I am at work, so I brought my charger to work, and have it plugged in at my desk, and if I leave it plugged in and on, it stays on for about 5 minutes, then automatically reboots. LED stays green, but phone will not stay on, if unplugged, or plugged in for longer than 5 minutes. I have never dropped it, and have babied the phone like no other, concidering I paid $400 for it. I'm a little bummed out, but cant determine if its a battery or hardware problem. Any advice/input for me from any of you guys? before I head to the ATT store, and cry for a new phone? Thanks a bunch for any responses to this.
*UPDATE* After I got off work, I went into my local ATT store, explained the situation, and was given a brand new replacement phone in like 10 minutes. I was under 30 days owning it, so he just swapped it out, barley any questions asked. (altho i explained my situation in detail as it was). So.... hopefully it doesnt happen again, or else I'll have to use the warranty. Anyways, Any insight on what may cause this would always be helpful for both myself and the community. =)

new news
EDIT: They got it Monday and I got it back Friday. Good turnaround! They fixed the problem, it works perfectly now. I recommend these people.
Ed
Sent it off to Cell Phone Repair(CPR) in Chicago that gave me an estimate of $95 (inc. ship. back) based on my description. They just called and told me it was corrosion around and in the power/usb port. They got it yesterday and will send it back repaired tomorrow with a 90 day warranty. No more saunas for this phone(it was only one! )
I'll let you know if they work out well or not.

Kaiser not charging

Hiya,
about an hour ago I plugged my nearly dead Kaiser to the standart charger and connected it using bluetooth to my notebook. I was very surprised to hear the "Batter is very low" sound a few minutes later. I checked the screen and noticed that the display read "Charging" no more. Blink - and it's stone dead. I replugged the charger and started the device again. Batter was at 1% and began charging. As soon as it hit 15% of battery life, it stopped charging again, although "Recharging state: Charging" status remained. I switched to USB charger to see if it makes any difference - and it did. It started discharging the battery! Now it's plugged back in the standart charger again and it reads 14% for several minutes now. It looks more like it's "holding it there" than charging.
I tried two different USB cabels, the "wall" charger (English is really not my native language, I don't know the proper word - sorry) and no luck.
Three or four soft resets, pulling out and returning the battery, nothing running in the background - just Phone, Data Connection and Internet Sharing. I'm using unmodified radio and Sleuth 3.0 ROM.
P.S. It looks to me that the battery is discharging much more faster than I was used to. As soon as I pull the charger out, the battery drops two or three percent.
Any ideas? I'm afraid my Kaiser / battery is dead.
EDIT: The battery is warm and I can see the "charging" icon in the kaiser's taskbar

RLOD
About the charging LED, usually yellow, turned to red? Just to clarify better your situation for all members here.

When the charger is disconnected, it flashes green, when I plug in the charger, it turns orange.

No RED led. That is a very good thing.
Do you don't have any spare battery already or maybe a friend will have one?
Looks like a fault battery - are you using it since when?

I bought this Kaiser about a month ago, but it's not new. The previous owner bought it in November, last year. The battery was healthy until today.

This sounds like a battery issue to me also. These are classic signs of a dying battery. The good news is that the phone is still trying to charge it.
Just as an experiment I took out my battery and put it on a multimeter. At 94% charged (when I took it out) it showed 4.09 volts and 1240mAh. I've had my tilt for 3.5 months now.

Try a hard reset could fix a program gliche if you have one..but it does sound like you have a "croaking battery"

ME TOO--
Was tempted to start a new thread, but figured someone might still read this one.
Last night my Tilt was fine,
and today I noticed that it was incredibly warm/hot to touch. After being plugged in and charging normally for a while, I looked back and noticed that the charging icon was not displaying anymore--just the normal battery icon.
This began last night as well, whenever my battery would hit 100% it would stop displaying the charging icon and return to the battery icon. I would then unplug it and plug it back in and it would go back to normal.
As of right now, it goes back and forth between refusing to show me the charging icon and showing me the charging icon. The light is yellow/orange.
Does this probably mean my battery is dying? Even when the charge icon refuses to show up, when I plug in the charger the backlight switches to the external power profile level of brightness.
It really came out of nowhere. I'm hoping it's some fluke that came out of nowhere, or that some strange registry key that decides it's going to jack up my hardware temperature, drain my battery, and not want to be plugged in anymore got changed.
It's about 2 months old, and I'd be really disappointed if the battery was already croaking.
O wise sages of xda-dev, please enlighten me. The thing charges really slowly now.

Xperia broken? red light under the ON button

Guys, i think my xperia is broken
last night my battery was empty so no big deal i thought.
today i've connected it to the charger to charge and pressed the ON button.
when i pressed it, a red light under the ON button started burning.
i thought? wtf? mayby because it's emty or something.
but after more then 1 hour of charging it still doesn't do anything.. and now even the redlight doesn't show up!
does anyone know what to do?

Hello dear friend, I sympathise with you I had this exact same problem and was worried sick for a day and a half that it was dead! the red light under the power button is the battery fail light (as far as i can tell) it goes on for example when you plug the charger in and remove the battery. I've found if you run the battery down to absolute minimum it almost seems like the X1 cant detect the battery any more and displays the red light. I fixed mine by removing and replacing the battery a few times and plugging it into the wall charger for a few hours. keep trying and dont lose heart, like I say it took me a day and a half (with a sleepless night inbetween

Also mine, but after five minutes it's wake up.
Try simply to remove battery, or performe a soft reset via hardware button with the stylus.

Let you X1 charge for an hour or 2 and it will start up again, guess this is when the phone don't get a enough power to start up.
(Guess it can indicate some other error as well but probably just lack of juice in the battery .. )

thanks guys..
it is still not working but i know that the phone it self is OK.
i wend back to the store and they switched the battery from another xperia.
it worked fine
i'm so happy right now. it's charging at the moment, but still not going on, well, i have to wait and see then.
again: thanks for the posts guys

Mind you... it might take a while! I had it connected to a cheap usb charger for a night (which wasn't good enough obviously) and it took me the better part of a morning to get it to life again with the SE charger. I find it most irritating that this sort of thing isn' t mentioned in the manual. At least not where I could find it. Things like a phone that doesn't want to start make you sweat horribly.

I have this problem with mine but still no luck
Been dead for weeks now.... Finding it hard to get a copy of the receipt too bah
Only had it a month too..

It's prolly one cell in the battery that are "broken".
Had that on my X1. There are 3 cells in the battery and if one of them doesn't work as it should, the battery only delivers 3-3.1 volt.
Your phone "wakes up" at 3.335 volt but dies at 3.1. I've been measure it myself.
My phone are now back in business with a new battery, a new batterycover and latest software. No problem if you have guarantee...
PS... Try to avoid one thing. Avoid heat in battery. Lithium hates heat.

You are right, man.
Usually, if you discharge a battery till the very last drop, it can happen that:
A) one of the cell goes beyond its safety level, and it "breaks". That's unrecoverable, AFAIK.
B) the cells gets unbalanced, and you nedd several charge/discharge cycles to get them balanced and fully recovered.
Add to this that Usb charging is usually unable to wake up an almost totally drained battery. This won't happen with a normal charger, but Usb charging voltage is lower than normal (of course, it's usb not home plug!) so it has not enough power to wake up the dead battery. If you leave your device in charge for some minutes, it will eventually manage to wake the battery.
However, I noticed that the X1 has a bad power management. Usually my X1 low level battery threshold varies between 10% and 5%. One week ago, at 10% it just shut down and won't recharge, showing me the red light over power button. Removed battery 3/4 times and charged with home charger, it gets recovered. Try to plug the charger, remove the battery and insert it again, doing all this with the charger always plugged.
In my opinion, that's really annoying, I never know when it *really* has a low battery!

yeah.. i had that with my P990i (symbian uiq3) phone the batter went in 1 day to 50% now it still has 80%

this same thing happend to me last night, i just pluged it to a wall charger & waited for an hour good thing when i pressed the power button it came back to life. was worried then and now its all good.

i had this on my xperia a while ago i think its just the battery is extremely dead.
after an hour of being plugged it in it turned on again

Red Power button Led
Glad to find this info, the red light gave me the chills at first too. My phone blacked out while using TomTom 7.4 on a stock unbranded NL Rom, after it had given me low batt. warnings. Now it's in the 'home plug' charger, sipping juice on the red light... I hope it comes out of it soon. Anyway, I was wondering if anybody has ideas on checking battery cell failure? Or battery diagnostics of some sort? It would be a shame to use a crippled battery just because you don't know it's operating below its max capacity. By the way, I'm not part of the lucky bunch in possession of a multi meter...
EDIT:
As soon as I hit 'post' the notification Led's display charging! And the red light's off of course. Guess the first post brings some beginners luck, hehe. Anyway, thoughts regarding battery diagnostics etc are still welcome!

Encountered this and according to the helpdesk, it's cos the backup battery is empty so he advised me to charge the phone for half an hour without the battery, and then charge it with the battery after that. Didn't work. Called up the helpdesk again and he said for some, they've to charge (without the battery) for an hour. Ok, tried that. But still doesn't seem to be working. Gonna just leave it charging (with the battery) for a few more hours. If still can't guess I gotta bring it down to the service centre.

there is a backup battery in xperia???

Remove your battery, wait 3 minutes, insert again the battery. If you have lost date & time info, no, there is no backup battery, otherwise yes, there is.

Well, anyway, sent my X1 for servicing. Over at the service centre, they tried to 'boost my battery' but couldn't get it working. So had to leave it there for them to work on it.

Just had this same problem, cleaned the battery terminals and hey presto...it's all good again..

Sent my X1 to the service centre with regards to this issue and they replaced the motherboard. They'd tried boosting the battery but no use.

Same problem.. this is what happened
ok, I came back from work an as usually i plug the charger in my xperia, the baterry left was like 30%, ok, then, I connect in the 3.5mm an autput for a big Radio so i can listen full music... so.. in a while, in my house there was a power down.. really fast one... like... 0.01secs... (like down and up really fast).. in that change my cellphone went down =S.. and sice today never get up ='(... there's just that red light in the power button each time I plug the charger on... any help?.. is the same problem of the topic? :S.. plzzz.. i dont have even a month with this pretty cellphone =( poor baby

Battery does not charge

So friday I noticed that the time would lag. sometimes 20 minutes, sometimes 2 hours behind, a soft reset put it back in normal time. Weird. Today I went to grab it to go to work as it had been charging all night long with a steady green light. I open it up and there is a red icon for the battery...23%..... I hook it back up to the AC adapter and see what it does, it shows a plug to symbolize charging and I check it 30 minutes later, it has dropped to 20%. My bluetooth is off. I now have it hooked up to the AC adapter and removed the battery, i have the battery on a charging dock and the TyTn II has a faint red LED where the normal area for the charging LED is. I am gonna see whats happening in an hour with the battery...
Has this bricked?
Time lags and battery does load now. Its only been in use for 9 months, never been dropped.
Pete

I love how people never think the battery is going bad and always think it's the phone right off the bat.
Try another battery and see what happens. Hopefully you bought it new and still have the warranty on it.

Okaaaaaaaaaay....I do not lack in the technical department. The battery charges on the dock and I got it up to 100%. I loaded it back in the TyTn and let it sit for 3-4 hours and it dropped to 90%. I hooked up the AC Charger to it and I got the steady light up on top like it normally charged before all this. The battery continued to drain. I now have it powered completely off and using my old KRZR....(smartphone to cell phone....wonderful) I have a new battery on the way for a week now so it should arrive shortly.
Some wiring leading from the Mini-usb to the actual battery must be corroded or something. I cant explain it...I do live by the sea, and if the contacts are not gold plated in there...I can see some problems occurring. I doubt the warranty would still be intact as I have upgraded the ROM to Win 6.1

tytn 2 not charging

hi!
i was just wondering, my tytn 2 is not charging, when i look at the battery meter, it says charging, but instead of going up. it goes down, the amber light
the signals charging is gone.
im sure its not the battery. coz i did get a charger, the one where u put probes on the + and - terminal of the battery, it charged. the battery is working now. however, i couldnt charge via the phone.
the red light came up before which indicates not charging so what do i do now?
someone suggested to hard reset it. i tried it but nothing. still the same. i reflashed it... nothing... now using the hyperdragon rom... still the same...
any ideas?

btw, when i plug in the charger, amber light is there... however, not for long, light turns off, but the charging / plugged into the charger symbol is there

as far as my personal experience goes, i have noticed this behavior only when the battery overheats while charging. in the hottest weather, this has NEVER happened for me. it only happens sometimes if my device screen is on WITH wifi WITH bluetooth WITH data connection WITH some heavy processing program running. this causes heating of the components and also leaves little power to charge the battery, because most of the charger's power is being redirected to power the components in use.
so, the device will charge for a few minutes and will interrupt the charging if the temperature rises. the charging will resume again when the temperature comes back down.
you can test if this is happening with your device by observing how long it charges before stopping, first without a fan and then with a fan blowing over the battery with the back cover removed.
if the charging lasts longer when the device is being cooled with a fan, then you are likely facing temperature issues.

Your same issue

solved my problem...
i was so pissed, all the solutions did not work... i decided to open it up
when i opened it, i saw that there is some dirt / corrosion on some lines
cleaned each and every one of them.
while it was open, plugged in the battery... then the charger...
after 2 minutes... battery bar went up! it is now charging!!! and
best thing... it also syncs!

Good to know that you solved your problem.

thanks so much. its ur post that really helped
