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.

Battery problems

My Diamond won't charge to full capacity! I tried to charge it overnight two times and the first time my telephone charged it was 70 procent charged after 1 night. (7/8 hours) and the second night (5/6 hours) with the same percent when i woke up. I had it once 100% but after installing hardSPL and the hardreset it drop instantly to 40%. (i just installed that , and nothing more.)
Connected the telephone to the charger again and i've got a full lit led ring. After turning the device on the ring went 'charging' again. The capacity was 75%. In windows.

Definatly sounds like a faulty cell in your battery
At least its not the phone thats broken, a battery is easily replaced.

I also have a strange battery issue! Mine won't charge if the Diamonf is switched on.
The Battery only will charge if I switch the Touch Diamond OFF, If it’s turned off, not only the display. With Running OS, when I plug the AC adaptor, it only show few seconds the charging breathing LEDs and then stops, the indicator also doesn’t show the charge symbol but the full charged battery instead but the LED indicator is not full white as it should be in full charge state and the battery of course drains down… I’ve tested with another AC adaptor, another USB charger, even car charger (I have the HTC original one), still the same behaviour.
Could this be related to the developer HardSPL? I also have this behaviour after that installation... weird
Any kind of help would be appreciated!

Its unlikely its the hardspl. I would guess hardware issue, but if it charges while off then thats unlikely too.
I assume you've tried a hard reset already to rule out any application interferring with it?
Also what happens when you plug into your PC? same thing?
My best guess at this stage with most likely at the top:
1) Software issue - try hard reset
2) Battery issue - try another battery, or once fully charged look for a big drop in battery very quickly. There are some battery manager/monitors you can download which can monitor the voltage for you. If you can show me the drop in voltage of the battery i can conclusivly tell you if the battery has a fault.
3) Hardware issue with the phone - that would just suck!

update: Replaced my battery and charged it through the adapter, full 100%.But here's something that is stranger... I installed the battery in another diamond and that battery indicator was 100% full..
I hope that it was a battery problem, because i had so much troubles with the diamond so far! The new battery is lasting much longer, it's been 6hours and it didn't even lost a bar. (still 100%)

A fully charged cell has about 4.3v across it. As its drained of current the voltage drops to about 3.3v, when its fully depleted.
The phone uses this voltage level to display the current capacity of the battery
If a cell fails in the battery, as its capacity reduces its not able to provide enough current. Power = current x voltage
If the phone tries to draw normal current, the voltage drops excessivly to conserve the above formula. This shows in the phone as a decrease in battery capacity. The voltage across the battery drops to below 3.3v before the remaining cells are depleted, and although there is still enough current to suply the phone, there isnt enough voltage. Overall there isnt enough power (P=IV)
A rested battery may show enough voltage for a short while (when you first put it in) but the voltage will drop drasticly as soon as any significant current is drawn.
This is a really common failure in a bettery, and you can spot it very quickly when you see sharp drops in the battery meter.

Don of course and even reflashed without installing any application, just synced with PC... same issue. In the mean time I even reflashed the stock SPL to try... and the Diamond is now charging in Off modus, so I'll turn it on tomorrow to give it a trial

I guess the Battery has an issue, but none is available quickly in my country, I'll have to try to order one abroad... let's check...
Thanks anyway for your advices...

I flashed my TD from 1.37.081 to 1.37.707.1 today and my battery went to 30 percent and not long after it wend dead again.
But there's something strange that i've discovered today.. my charger charges my phone really slow (with original cable and charger) but with the 3rd party adapter i charged todat (adapt htc, specifications are the same of the original adapter) it's normal and my phone doesn't warm up ( max 20 degrees celcius) so much as with the HTC adapter (40 or more degrees celcius?).

Check the current on the 3rd party charger.

output 5V/1A , same specs. input is a little different (110-220hz, 0,2A) against (110-220hz, 0,15A).. but that isn't a problem right? The output is the same.

Thats really strange. Yeah its the output that matters,
There should be no difference at all!

Yeah.. my Touch Diamond is f**** up as h****.. that's not only the problem. I used some GPRS today and my phone makes noises just like when you put a telephone next a speaker and it receives sms/calls. That's when i'm surfing on the web :O!
On top of that, my speaker quits after x seconds/minutes and doesn't make any sound at all and then works after x seconds/minutes. But it doesn't work after x seconds in the Touch Flo mp3player. So my ' precious diamond' is pretty worthless right now.

Check your settings: settings > power > checked off the "when device is turned on, do not charge...." ?

That noise is caused by a harmonic of the GSM signal. It sounds like the grounding is not correct, either for the speaker or possibly a whole section of the circuit.
Not good!

I have the same thing - battery left on overnight does not result in 100% indication. Yet it often creeps up much higher after I have removed the charger! Have come to the conclusion that it is a software problem - terminal voltage tests OK.

-hi Bakman, of course this was my first check Anyway, is getting worse, now it even won't charge when switched off So I'll send it for repair I guess... I hate to wait for a new device, pay a huge amount of money for it and when you finally get it, it's defective

Same issue here. When charging the phone while it's *on*, it results in the indicator stopping at 75%-80%, no matter how long I charge.
I think once when charging through PC/USB, this did not happen and the battery did charge to full.
A soft reset results in the indicator displaying 100% battery however.
So is this a battery problem, or software/hardware problem?

Sounds definately like a s/w problem to me, they will have to provide a fix in a ROM update I guess. Mine is OK at the minute though. Is yours UK or grey import?

Err, I bought the WWE version in Holland. Actually someone bought it for me, but that's not the point.
I did find out that using the advanced config tool to disable the setting "GPRS auto attach" really saves a lot of battery power! Yesterday my phone was idling the whole day and night, and battery only dropped 10-20%.

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!

B) the cells gets unbalanced, and you nedd several charge/discharge cycles to get them balanced and fully recovered.
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..
Regards,
Astoroth

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

Tilt Battery Issue

I have OEM battery and it was working great for last year and half. Now a days when I put it in charging it charges the battery but my screen does not show it correct percentage it is chaged for.
If I put this battery in my wife's phone it show it is charged 100%, if I put 100% charged battery from my wife's phone in my phone it show 67%.
If I put it to charge via my phone I get led showing correctly that it is charging, even in battery status show it is charging.
Issue is it is not showing correct percentage (I think) what my be issue battery, phone , rom.....?

Old battery!!!

but same old battery works fine in wife's phone
but same old battery works fine in wife's phone.

Try cleaning the contacts on your phone.

they are as brighte as silver
they are as bright as silver but issue continue.

So this is normal?

Does a year and a half make this OEM old? My OEM Tilt battery, also 1 1/2 years old, just started giving me only about an hour of talk time from a full charge. So this is not unusual? It's annoying as h*ll, that's for sure.

I've seen the same issues between my Tilt and my wife's Tilt (actually my wife replaced her Tilt with an iPhone), so I should say between my first Tilt and my second Tilt.
The problem happens once every two months or so. I usually put the battery in the phone that shows the higher battery life and let it drain down to zero over the next few days. This has solved the problem for me so far.

If he is using a different battery in the same phone, and getting the same result, I would say its not the battery.
I'm having a similar issue, where after a full charge the phone works fine for awhile, then shuts off if i use the web browser or gps for more than a minute. After I turn it back on(and if it lets me) my battery reads only about 5%. I thought it might be the battery but even though I bought a new battery, I still have the same problems.
I've even reflashed to a new rom to try and correct the problem, but without luck.
I think maybe a year or so is about the life span for this phone. Or maybe a few escaped quality control, and we just happen to be the lucky ones.

I had a similar issue with my kaiser, then it started not charging the battery intermittently which meant id constantly wake up with a dead phone in the morning after an allnight charge.
Then it stopped charging altogether, HTC sent me a new battery which did exactly the same.
So i sent it off and it turned out to be a motherboard issue with the charging circuit.
Hope that helps

full overnight charge only charge to 70%
when i put battery for full overnight, it charge only charge to 70%. I will give it a try to drain to 0% and then see what happens. I am sure this is issue with phone and nothing to do with battery but still can not solved the problem. Can not send to HTC as warrenty already passed.

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.
