Battery drains damn fast (90% over night) - Touch Diamond, MDA Compact IV General

Hi there, since I can't get my head around this I wanted to know if you can help me.
My parents own since ~2 months now each a XDA Diamond (HTC Touch Diamond = MDA Compact IV = XDA Diamond). They were using both the latest O2 offical firmware (Version v2.03.207.2 from http://www.o2online.de/nw/support/downloads/software/xda/diamond/xda-diamond.html).
Well both had a hard time when they started to use their phones - the battery drained pretty quick. Since then the battery life of my dad's xda developed well - over night it looses almost now power (1-2%) while my mother's xda looses up to 90% over night!
Since both use the same settings, the same software and the same firmware I can't get my head around what the problem is. Swapping the battery doesn't help - my mom's xda still drains its battery damn fast.
What is there left I can do about that issue? Might her xda plain be broken?
Hope you can help!...
EDIT: Have almost forgotten this - when my mom charges the battery up to let's just say 30%, turns off the phone and takes the battery out, the phones has 40-50% when the battery is inserted again. A miracle?!?

have same question ????, maybe i must buy 1 more battery

Might help, might not. The OP clearly stated that when he swapped batteries the issue was still there...

Definitly not a software/battery issue (you already stated that yourself). The XDA is probably broken. My advice is to just return it to O2 and ask for replacement.
If you had flashed the ROM yourself it could have been a radio driver issue, but since you both use the latest official and the drain is so major I suspect a broken device. Don't try to fix it yourself anymore, just return it.

It isn't. Battery percentage is calculated based on battery voltage. A battery has a semi-specific voltage at each level. The "percentages" are nothing more than mappings for the voltage levels based on the average voltage the batteries give at each level after being drained/powered up for a bit.
If you take it out two things happen:
1. The battery cools down
2. The draining/powering up of the battery is stopped
both are known to (temporarily) increase the battery voltage once they are reconnected to a circuit (=inserted back into the phone). The actual percentage doesn't really change ofcourse. If you let it stay for +- 30 min the load will be "correct" again.
Didn't you have a gameboy when you were young? I've learned through trail and error that when your gameboy battery dies, if you take them out for +- 1 min. and put them in again you can usually get another 15 minutes of gameplay
(the reason this is chemical. If you're really interested ask or send me a PM )

If you're referring to the USB -> extUSB (HTC USB) cable, it shouldn't matter: extUSB is 100% backwards compatible with miniUSB (standard), except that extUSB has 2 more lines for audio/antenna. So charging with extUSB or mini USB shouldn't matter.
Also, the origional HTC USB adapter is just a generic adapter that delivers +5V on the USB cable.
Also, why not just post your solution here in the forums instead of PM?

ok first of all iv'e had 3 diamonds and none of them held the charge using a none htc usb cable
secondly using a none htc cable is fine for data transfer but you must uncheck the charge when plugged to pc in the power options
trust me had this problem many times

HTC TyTN II: Unrecoverable Power Failure

Hi, I have recently acquired (mid Sept. 2007) a TyTN II device: really a very good and nice device ... till yesterday.
Maybe my experience could be shared with some of you...
Yesterday my device suddenly turned off apparently because battery very low (i.e. less than 5% according to the manual): this is strange because as far as I remember my battery was charged enough to survive more than one day considering that I did not use Wifi/Bluetooth or many phone calls.
By the way, the problem occurred when I attempted to recharge the device: it spent hours under recharge but the power led never become green, but remained orange. I attempted anyway to startup the device, but as soon as the Windows OS started it automatically shutdown because battery too low was detected.
I performed several software reset and finally an hardware reset, while attempting also to recharge it also via USB but without any positive effect.
I contacted HTC which suggested me ... to provide back the device most likely for being replaced according to the DOA (Dead On Arrival) policy.
Please note that according to some tests I performed on the battery, this seems to be charged and the problem relying on the device or OS which do not recognize it as charged but so low that no operations are permitted.
Has some one experienced a similar issue with this new HTC device ?
Cheers,
Max
GF's 8125 did almost the same thing; wouldnt charge past 10% and kept sending notification after notification; this was literally right out of the box. Cingular/AT&T suspected the battery but replaced the 8125 as well.
So far I have not seen other reports of this for TyTn II. It is however a reasonably common problem with many different brands of phone.
Mike
Could be a Power managment issue its not uncommen at all. things go wrong in all electronic devices think of the millions of Kaisers that will be sold in the coming months a few are bound to messed up from the factory. Its like buying a car you know ****s guna happen but you buy it anyway since it looks really nice that first day!
Did you all charge using the supplied wallcharger instead of via USB?

Make your kaiser power off, and use wallcharger. If it still doesn't work, call for HTC..
Some problems are solved by letting the internal battery drain, by leaving the device without the battery for a couple of days.
That issue can happen if you (almost) run out of battery.
Best practice: NEVER EVER run down your battery below 5% ! As soon as it reach 10%, switch off if you dont have charger at that time.
You might go below 10%, but take the risk .... !
It is known to us that the new Windows Mobile 5.0 supports persistant memory (your data will not lost when the battery runs out 0%), but it does not say that you will not be able to charge the battery!
More explanation? And how to revive the battery?
Read this thread:
http://www.modaco.com/Warning-Battery-Chargin-t233233.html
It is well explained, how that happen and how to recover the battery

ey man, i followed the recommended procedure for the three firsts battery charges. First i plug the PDA and let charge at 100%, then i let the battery goes to 0% (yes, the PDA goes off, of course) and then plugin onto the wall charger, and let charge to the 100%, repeating this procedure three times.
I do this also with my previous PDA, Hermes. And no problem leting the PDA going to 0%...never see this problem before.
What is the supossed problem leting the battery goes to 0%?
Regards.
EDIT: Found this interesting information about LiIon... http://en.wikipedia.org/wiki/Lithium_ion_battery and http://www.batteryuniversity.com/parttwo-34.htm
jcespi2005,
I simply dont know I just shared the link that I knew from modaco which is useful in this case.
Maybe this is not 100% the case, but as I said "best practice" ... something that it is better to follow to avoid this issue as you should read already that quite a lot of people affected by this very low depleted battery.

The modaco thread talks about Wizard, i think it's not 100% the same as Kaiser, cause is not the same battery, and the hard charge interface on the PDA can be different. I'm going to make a deep research about model and manufacturer for the Kaiser Battery, to see what can be the issue.
Anyway, i let my Kaiser goes 0% three times and charge fine for the three times. So i beleave the issue is not related with the battery itself. Can be the charger? don't know...
What is the model and manufacturer for your Kaiser battery, please?
Mine is Samsung model KAIS160.
Just checked and I have the same battery, SAMSUNG KAIS160.
I have now seen another report on another forum with this problem (Kaiser). I suggested the standard method as used when the refusing to charge issue arose with the Hermes (TyTn).
(It worked by the way!)
i.e.
1
Remove the battery for half an hour or so
2
With the battery still removed connect and switch ON the official (1000mA) MAINS charger (Not other brands that deliver only 500mA)
3
Now insert the battery
4
Wait for up to 5 mins for the Red LED to change to Orange
Repeat steps 3 and 4 if you have no success after waiting for a reasonable time.
(If that fails then elsewhere I have reported the technique of delivering a charge to the battery using a couple of AA batteries)
My view for what it's worth:
Although in rare cases there may be a faulty battery, in the main the problem is not caused by the battery. The likely explanation is that the circuit that detects the battery's presence, fails to detect the battery when the battery charge is very low. In other words there is no problem with battery but the battery charge detection circuit is either frozen or does not switch on when the battery charge is too low.
This issue I see reported across many brands of phone and is not a WM specific problem.

Many thanks for the information, this confirms my suspects about the interface to the battery, and not the battery itself... i see this issue time ago with one Nokia 6100, and solve it with the same procedure you write. Sometimes LiIon battery gain some charge if you place in the refrigerator for a while (cool helps LiIon batterys, and warm hurts).
Regards.
EDIT: More info about charging LiIon battery here http://www.batteryuniversity.com/partone-12.htm
Seems there is no need to make three charge/discharge cycle before use the LiIon battery. Simply you can use and charge in any moment. Really is better sorts and many charges rather than less and longs charges/discharges.
Power Failure.
Hi guys,
Well the USB did the trick.
Don't forget the Red Wire is the + (Positive)
and
the black Wire is the - (Negative).
A few minutes holding in place did the trick.
Thanks a lot for this thread, I actually had the feeling that I have lost the Kaiser.

Hello,
Take a USB cable (the one like you use to sync your pda) cut it in the middle, expose the wires inside.
The red wire (+) is to be attached to the PLUS of the battery, and the balck wire (-) is to be attached to the minus of the battery.
About one minute and fater re-install the battery and try charging again, this should do the trick.
You can also use 2 AA batteries in the same manner.
Yours,
Ronen
just happened to mine after only a month. Contacted att and the forum and had to get it replaced. So far nothing wrong with this one!

Hi Mike,
Had my Kaiser sent to a lab, they are checking it but they are saying it is a faulty board.
The battery is ok although I bought a new one and tested it to find still the same problem.
Thanks.

Battery problem

Hey guys.I just got my Xperia X1 and I noticed that even if I charged my phone to 100% after I unplug the cable (I use my USB cable to charge it) that battery meter goes to 95% the second I unplug it.If I send a text or two it will go lower.By the end of the day it will be around 50-60% left.I tried looking for a fix about that but nothing came up.
Is that a common problem for the X1?BTW the phone is brand new and the battery is the original one that came with the phone.
Thank you in advance
First I think you must charge your (new?) battery at least ten times to get full capacity. Secondly I think I remember there's a way to calibrate the battery. Look in settings or even better the manual or perhaps best, search the forums.
GL,A.D
Thank you for your answer.I checked the forum but not much came up about recalibration.I checked the phones settings and I can't find anything about batery calibration
are you on a stock rom or a custom one?
also if you leave your xperia plugged in once it reaches 100% i believe it simply stops charging, so the moment you unplug it you "real" battery percentage!
No I am using a custom ROM.I always unpluged the phone when it says full next to the battery metter.
thats why I don't like charging via USB - it's unreliable and slow, always was
if someone knows how to solve that with a recalibration pls tell
I think its a problem of usb charging. I get this problem when I charge my phone with usb. I havent had this problem on charger. Maybe you usb is a bit lower voltage, so the battery isnt fully charged, but its not charging anymore so the percentage is set to 100% and rapidly decreases after short usage.
I think if you use a charger and do charge your batter a few times full with charger, the memory effect should go away.
Just correcting lpgsk, it's not the voltage, but the electric current of the USB. If I'm not wrong the charger has a 500mA current.
charger output 700mA @ 5v
My suggestion is, if you have to charge it on USB, you should charge it when its off. The charging current should he higher since part of the energy wont be used to keep mobile standby. Therefor it should be able to get more power to battery.
2nd option, buy USB mini Y-cable. It is 1 miniUSB -> 2 USB cable. So you put the other end to 2 USB slots for more power.
like this:http://cgi.ebay.co.uk/USB-A-Male-to-Mini-5-Pin-Y-Cable-for-external-hard-Disk_W0QQitemZ330414581897QQcmdZViewItemQQptZUK_Computing_USB_Cables?hash=item4cee3e6889

It must have been my memory who failed me this time. I can't find any way to calibrate battery either. Sorry for that!
Saw that you're running on a custom rom so I guess the phone is not brand new. Question raised is, how old is the battery?
Searched Ebay for whatever to my x2 and found the batteries (same in X1/X2) damn cheap (fakes or not). Why not buy a new battery and test?

Hey there.The phone was brand new when I got it.It came with the standard WM 6.5 I just installed a new ROM.I tried charging via the wall charger and it seems that the battery lasts WAY longer then charging throw the USB cable.
Thanks a lot guys
PS:One thing (has nothing to do with the battery but I don't want a new thread for that).All my received text messages are with a different time then my phone.I would say around 3-5 hours difference.I searched online and I found more people with this problem but I cannot find a fix for it.Any suggestions?
Thanks again to all of you that answered
Anyone??!!

[Q] tytn ii battery issue

hi guys,
when i power on my kaiser (with the stock rom) and the phone gets to the welcome screen i can hear a dead battery sound and the phone powers itself off. tried hard reset, flashing a new rom, changing radio, buying a new battery, charging battery using charger wires..nothing seems to work . If i flash a new rom like wm 6.5 the phone shows me radio version, protocol version and rom version ( R G D ), the light dim's and the phone shuts down.
when i connect the charger a yellow led turns on..i left the phone charging for one whole day but the light is still yellow
any solutions? thanx in advance
go look for the exe file called powerdetect.exe this is a small program listed in the TytN II service manual that is used to check the battrey health. I suspect the batt needs to be replaced.
the battery is ok. i've tried with several batteries and the result is the same
What charger are you using? Motorola v9 charger wont do. I had similar power off issue when starting up a unused unit. Only able to charge with original charger 5v 1000ma. OR try charging it through the PC USB port. If you have a notebook, just leave it in sleep mode for overnight charging
I've got a similar problem but usually when i make or accept calls the phone switches off
My phone is a Kaiser 130 which runs on 5 volts but the battery i got with it (bought it on ebay) is Kais 160 which runs at 3.7 volts???? Also the mains charger i got with phone is a 5v.
I just did a power test using the program below till the battery was dead and then plugged into my laptop to recharge and within 2 mins battery is up to 72%???
can anyone who has a Kaiser 130 from new tell me the original battery voltage and code please
power detect download is here if anyone wants to download

every kaiser has a 3.7 volts battery..are you sure the phone turns off when you make or receive a call? My guess is that only the screen turns off (sleep mode - same as pressing the red button) because your ear can touch the screen and acces random menus etc

which flex cable are you talking about? Do you have a second unit that you can do a part swap to see if it is actually the cable issue?

Hi Giany,
had a battery problem not the same as yours by the sounds of it but solved it by installing the orange shipped rom which comes with radio.
might be worth a try.
good luck

I have the same issue... .-(
The phone just switches off completely with any hint of longer usage (phone call longer than 1 min or so, garmin mobile xt barely makes to searching of satellites). I use original stock ROM.
Unused (no phone calls) it can last for two days. I have tested it with brand new/unused prepaid sim.
I took it to authorized HTC service center, but unfortunately they do not support it any more due to lack of parts.
Anybody else have this issue? Or clue to what might be wrong. I really love this phone…

Same / Similar Problem
I have the same (or at least quite similar) problem here. Only with me, I think it's the micro USB port that needs changing. There is two visible cracks which maybe stopping the flow of electricity.
When I plug it into a charger, either wall or to my PC, it turns on fine, and can stay on aslong as it's plugged in. (sort of makes it like a desktop then, doesn't it ). The problem is that it doesn't charge.
I am using ahmed fikry's 6.5 Kaiser ROM but do not seem to have had any problem with it so far. I also run Ubuntu and Android through HaRet.
replacing the flex cable worked for me..i found one at about 30€. Hope this helps

charging very slow!

help,my note now charges very slow 4-5hrs without using.
it depletes if im using it while charging.
could change rom,kernel be a fix?

i just bought an extra battery.lets see how it goes.
i noticed my old battery had a small bump in the middle seems bloated. hmm
i remembered last time i used xperia s charger trice,it has 1.5kA it realy charge fast. i think that caused the problem?
when my sister charge her xperia s, the charger just explode.. and she scolded me why am i using her charger.
im using my old charger which is 700ma but it charge just fine. lately when i use the xperia s charger and went back to my old one,it was acting strange. it charges really slow and if i use the phone,it depletes even when charging.
im going to flash another rom,and see if its rom related or the battery isue.
thanks for replying.
ok,im on with my new battery but still depletes while im using it. im just browsing. on the widget it say im currently charging with 1000ma. wierd, dont know how to solve this.
[SYMPTOMS I HAD] it would charge very slowly, if the screen is on, it would actually discharge. When the phone was off, it would slowly charge (i.e. >5 hours to full charge). and it would discharge very quickly (i.e. 1% per 2~3 mins). When the phone was off, it would charge sometimes and sometimes not. Figured that when the phone was off, you really are negating much of the software influences so this could be a hardware issue, however, wanted to make sure before going down the hardware route.
Did some research, searched the forums and searched some more.
I had tried 5 different chargers, 3 different USB cables and had bought a replacement battery.
Steps taken:
1. Cleaned with thick paper - no change
2. Cleaned with thick paper & rubbing alcohol - no change
3. Cleared with Compressed gas - no change (on first charge, there was a change but then back to normal)
4. Attempted to clean with vacuum (with finer nozzle) - no change
5. Used charging apps from playstore - didn't show charging details - considered the port was faulty
6. Tried to find default references for charging as mentioned in one of the forums - unable to find it
7. Found a replacement USB port charger board and replaced it - working fine
So it could be the actual port is faulty. If you symptoms match, it could be time to take it into the service centre, restoring to stock first of course. The note I am using had slow charging for about 2 months prior to really slow charging.
i had change the usb port and its back to normal. 2hrs at least and its full.
Fingers crossed, thats all you need.

Battery 100% On, 80% Off

phone says 100% but says 80% when off charging
Tried:-
1. 2 different battery callibration apps
2. charging 100%, depleting battery. repeated process a couple of times
3. Switched to Stock (Rooted), 2 Custom ROMs (Waited till it was 100% on both on and off before flashing)
Notes:-
1. Battery seems perfectly fine (takes a while before depleting and doesnt deplete before 0%)
Currently using stock rooted
l would start with replacing the cable and charger to make sure you are getting a full charge. Then monitor the usage time on your phone over a few weeks and see if the time to empty is getting less that is a sure sign of a bad battery
Recheck with another fast charger. Generally, we cannot say if is a faulty cable or you have an faulty adapter. I hope the device chargeboard is not shot/motherboard driven related issue. Also, have you recovered the device using Samsung Kies- Emergency firmware recovery?

I tried - original cable with original charger 6hr
- original cable with apple charger 2hr
- different cable with original charger 1.30hr
- different cable with apple charger 2hr
(Used different fast chargers too, same results)
I tried a smart switch recovery. Same conclusion which makes me think its a hardware issue

With original charger it takes 6hrs!!! Holy ****
I think its a usb port problem for sure.. Do one thing while connected to the charger go to device maintenance and open battery menu and see if it say charging via AC or USB if while us8ng the original charger it shows Chaging via USB then certainly its the port that has gone faulty..
Hit thanks if helped
Hello everyone! Though its not the right place to ask the question but I have been seeking solution to my problem from months. Long time before, my Galaxy Note II started to behave differently. Whenever I charged it completely, the phone worked normally till 75% to 80% and all of sudden a =low battery warning indication appears and phone proceeds to shut down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon it reaches round about 80%, it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery

I have this weird issue thats been bugging me for a while now. The phone says 100% when im on it but when i power off and charge, it says 86%.

I have noticed the same issue, I think. I suspect it is a general bug.
Guys, try charging your phone while in Android. When it reads 100%, switch off your device. Either leave the charge cable attached or reattach it after you have switched off. Now wait for the off-line charging icon to appear. Unless I'm mistaken, the percentage won't correspond with whatever your phone reports while your in Android. If Android says 100%, this will be a lower number. And off-line charging will keep on charging until you reach 100%.

Sorry for the late response. Internet finished, had to wait until the renewal date. During this time, i wiped the rom and re-installed it (Khongloi V11). Since there was no internet, i didnt sign in any accounts, Switched off the location. The phone surprisingly took 3 days before reaching 0.
Indeed, it says USB Charging 6hrs. I sometimes keep plugging and unplugging, it changes to A/C 2hrs.
I have this problem too. But I change batt_capacity_max to 1000, phone on 100% phone off 100%. If we recharge to full it will return to the same state (phone on 100, phone off ~80) so i need to change again. I don't know if this destroy my battery life ? I don't know why. I thought I'm the only 1 who have this problem? (sorry for my bad english)
I think this may be a software/firmware problem, not a problem with the battery.

I figured that was the problem but i tried it with three different roms (Khongloi V11, Final, Stock).
Maybe it's some kind of battery protection thing created when your battery is old or something?

The various ROMs may all use the same battery raportage code, which doesn't account for this discrepancy. After all, most ROMs are just fancy reskins of stock Android.
That said, maybe Samsung support can shed some light on what's going on.
On a side note? Is there anyone who reads this thread, whose reported battery charge (in percentages) is the same in Android as when the device is switched off and charging?
So... any solutions?
