HTC s640 Battery Issues?

Hi Folks,
My s640 seems to have developed an issue with the battery. It will get to about 50% and stay there for most of the day then suddenly I get the low and critical warnings, then off. The warnings then off sequence happens within about 10 seconds of getting the first warning. On one occasion I got the low and critical warnings, but then the phone reported 268% battery remaining.
Is/has anyone else experienced this issue or anything similar? I'm wondering if it is the phone or the battery.
Thanks.

I am having the same trouble.
I'll fully Charge my battery and then disconnect it and us it for about 10 minutes and suddenly it will drop my call, turn off my bluetooth and disable the radio (network), and if I don't plug it in, within 30 seconds it shuts off. If I remove the battery, hold the power button for 5 seconds and the put the battery back in and turn it on then I have my battery shows 90+% free.
I'm not sure if it's the battery or the phone.

have you tried running the battery till it won't turn on the phone. Then charging it up again?
maybe a hard reset may help?

Yes I too am having this issue since rom upgrade so is a friend, he just purchased new battery from Telus but they shipped wrong one. Will update if new battery resolves his issues. I went throught three phones with brand new battery they all did same thing Battery is not HTC 20 dolllar aftermarket one (just before warranty expired). Have gotten 400 credit for new phone but nothing like this one out there except Touch Pro Diamond and I hear even with new battery that phone battery life is too short to last through day. Get feeling Telus broke something in software with Rom update used to be when phone battery was expiring a red light would blink (opposite of blue tooth light) now it is only notifications from WM that phone battery is critically low and shuts of radio etc. yet you plug phone in and it's charged 10 minutes later makes no sense. Rechargable batteries voltage change with charge the interesting thing when I pull my battery the voltage is the same charged or just after error messages (I have a very expensive True RMS Voltmeter from work that has been calibrated in last year) but without load this isn't an accurate test. Does make me think something is not right and beleive it software related for more see my post in Howrds Forums under phone model.

I am having the same issue after the ROM update, not sure if it's the cause. Already replaced a battery on warranty for not holding charge. But now I have had the phone over a year so telus wants me to buy a battery for $80. I know based on this information i'll be wasting my money.
i want stuff to work for more than a year what the hell is money good for?

any fixes or updates wether the new battery helped??

I replaced the battery on my phone and these odd issue I was having are gone guess we have to face the fact that you need to purchase a replacement once a year hopefully it will last a year my problems start just short of a year.

I just got my new battery from here http://www.longlast-battery.com/productCart/pc/viewPrd.asp?idcategory=0&idproduct=17483
I will post after I get it full charged and try it for a day or two
where did you get yours from?

well the battery didn't even last an hour on the way to work.
#1 it was similar but 2-3mm shorter than the OEM and barely touched the contacts on the phone.
#2 charged overnight ok and said 100% charged then withing 20min it said low battery then died shortly after
#3 would not charge a second time (on 2 of my wall chargers, two usb and 1 car charger) Just the red light would light up. Tried jiggling the battery but nothing not even a flashing red light.
so much for a battery bought from the US. Waiting for RMA

I purchased a battery from E-bay and it would not charge at all. Existing charge in battery was enough for me to know that my issues were battery related after all as phone lasted for quite awhile. Tried charging ebay battery for close to 12 hours no go, so returned it for full refund. Called Telus because my calls in were while I was under warranty still but it had since expired they credited my account for the price of battery over a couple of years (1.5 batteries really) to make up for battery not lasting more than a year...hope that makes sense. Doubt I will buy another HTC with todays battery technology there is no reason one of these batties can't last 2-3 years if taken care of. Just a money grab telus/htc on their part in my opinion.

Gave the battery I got from longlast-battery another try.
the battery is CS-DS640SL 1250mAh 3.7V
I got it to charge by turning off the phone and plugging it into a usb port on my PC. Took about 6 hours to charge to 100%.
Won't charge when phone is on which is weird. Even at 90+% charge.
Lasted a full day without charging. That's a good thing I guess. Even when I restarted, it didn't lose the typical 10% drop in charge the other battery does.
I'm going to discharge it and charge it three times to see if it starts working properly and letting me charge it normally. Was a tip someone gave me. Won't hurt anything, and if it doesn't work I can still send it back.
Curious what you guys think. do you think it's a bad battery and I should just get an exchange, or I should just get my money back, and shell out the $100+ for a Telus battery?

Well the longlast battery test failed badly. Lasted about half a day with minimum calls and data use. No wifi no bluetooth. After it died I took it out and let it sit for a bit as the battery was fairly warm. After I put it back in, it said I had about %40 left. Very odd. And it lasted for another two hours before dying.
Now it's back at the won't charge stage. So I finally got an RMA number, so this one is going back.
Hitting Telus on the way home to pony up for a new battery. Getting the extended one as it's only $20 more. Hopefully this one will last more than a year - then I can get another phone (got to love 3yr retention contracts that end early )

I've created a Facebook group to act as a petition for everyone with the notorious battery life problem.
Join the group here, it's open to everyone:

Share your experiences dealing with Telus positive or negative ones.. or tell us if you've been able to fix the problem by hacking the device. Anything at all that will help the people still stuck with this phone.

I have done some efforts regarding battery capacity measurement Just lookup this thread: http://forum.xda-developers.com/showthread.php?p=5558383#post5558383

battery drain problem on my SPVC600

I have 2 SPVC600 phones and one is not even 24 hours in standby before the battery goes empty, whereas the other phone is in standby several days. I tried several different "virgin" ROMs on both phones, several different batteries, still the same problem, one phone just sucks the energy out of the battery like crazy.
Anybody knows where the problem is and how it could be fixed?
Thanks

Same Here...
Hi, i know that this is a old thread, but... the same issue here, i have a T-mobile SDA, replace the original battery that come with the phone 2 years ago, this battery die and ebay a fresh battery again, but... nothing, goes empty in less than 13 hours with the fresh and new battery (with the old one at least 4 hours before die under nitrogen´s wm6 rom), any suggestion? (i clean the phone of programs, change roms, downgrade to original WM5 but... nothing, only 12 to 14 hours and empty ), the new battery is a "OEM ST26" from sanyo...
Until this day, my tornado was the more reliable and trust phone that i´ve had
Can you recommend me any procedure for test the phone... do you think that is a usb connection Issue, i read in a lot of threads that this could be Rom upgrade... ´coz the new drivers, componets, etc.... any help ir really appreciated
Greetings from Colombia...

Usually the original batteries are the best you can get. Even the (now very old) original ones (Sanyo ST26-C) still have their original capacity and I have not seen a single battery of these that has failed until now.
If you see such a drain from the device you could possibly disassemble the device and clean it. If that does not help - sad :-(
Does it make difference if you charge the battery on the device being off or while OS is running?
If you have volt-meter: what is th battery-voltage when empty/fully loaded?

Hi Tobbie, thanks for the reply, yeah, i follow all procedures for battery maintance, i try charge with the phone off, phone on (with radio turned on and off, really i only see a difference of only 1 1/2 hours...), this night i try clean with isopropilic alcohol the contacs between battery an phone and i see... i noted something peculiar:sometimes when i plug the AC Adapter or connecting to my desktop, the led indicator (in this case orange), dont turn on, sometime this led appars and dissapear passing 20 seconds but full charge the phone (i see this in seetings=> energy configuration => 100%)... other times this light is hold until this change to green (fully charged), but ever the same result, lees than 12 Hours... this happen with both batteries (old one and fresh buyed from a reliable seller 15 days ago...)
I download awhile the service manual for tornado but... Scare... i really love this phone, really i have now a LG Incite, but this phone is my "backup", coz all time buy and sell phones, but this since 2005 "sleep with me...", if after clean contacts i dont see any change or fix... No mercy with tornado´s LOL...
and i want with all neighborhoods a voltimeter, can you tell me about the standar values for this battery (my knowlodgement about electronics are limited a lot), i post my results here after my test...)
Thanks a lot, i hope that you can help me later (and sorry for my ugly english)
Greetings from Colombia

This sounds weird, but the only reasonable source of evil is that also your other battery (equally aged, but unused probably) is chemically dead. It hardly ever happens that the charge-electronics is going mad somehow. With the many Tornado that I had on my desk, not a single one had problems with this part. For some devices I have seen that the batteries were stone dead - and these behave as you describe it.
It looks as if the battery has lost its capacity. A fully charged battery has a capacity of roughly 1100 mAh. With a drain of ~75mA (for the fully lit display) this will last 14h and 40 minutes. So a similar power drain would have to suck the juice off the battery - which I doubt that anything will do. If you switched off all radio parts (GSM, WLAN + BT) there is nothing left that drains the battery like this.
You could try to check how long the batteries will last when you have the display light draining the battery additionally. For this part it is well known how much it drains (see above) - and if you see that the battery lasts half the time of what you said before - then the battery is ok and the device has some mysterious power drain. If however the battery only lasts a few minutes with this defined load - then it is surely dead.
Check the battery capacity link in my signature to get the tooling for measuring this easily.
Voltages should be measured with a digital Voltmeter if you have access to one. They are for dead batteries not much different to good ones if you do not apply load, but a fully charged LiIon has around 4,2 V and discharged in a Tornado around 3,55 V.
The Tornado will shut off at around 3,55 V but if the Voltage is much higher when removing the battery and measuring the Voltage - another hint for a dead battery.
Good luck

[Q] Is my phone dead? :(

1. The phone won't turn on
2. The charging indicator doesn't light up when I try to charge the battery.
3. One of the sensors on the top left turns dim red in color when I connect the charging cable
4. I can't hard reset either
thanks

Did the battery die all the way? Or did you flash a radio without checking the md5? If its a borked radio install say hello to a 500 dollar paper weight if its the battery your gonna have to charge it in another phone cause I'm not sure if cwm 5.0.2.7 has powered off charging

Yes we need a couple of info first. Also we need every information we can get in the last events before the phone got bricked. Like what did you do? what ROM? What's the status of the phone? Battery?
The more the details the better we could assist you.

Sounds like when my first Mytouch 3g broke, it would turn on the first couple of times going into a bootlope at the HBoot. It also didnt respond to charging or any other battery i tried.

Thanks for the reply strapped. I haven't flashed a radio. I did flash the virtuous infinity rom though. I'm not certain if that affected the radio. I did, however, let my battery die all the way. Do you know why one the sensors on the top left corner turns dim red when I connect the charging cable?

Oh crap the battery die all the way problem
I think your battery is dead.s
Saw dozens of problems like this on the my previous device's forum.
Li Ion batteries have this fuse inside it in which it trips off when the battery gets discharged to a certain voltage. If it does your battery goes into a suicide mode in order to protect the phone.
basically the best thing to take good care of your battery is not let it drain lower than 40% and not fully charge it to 90%.
discharging it too low drains it's lifespan drastically. While charging it too high also drains it's lifespan.
Over-discharging Lithium-ion
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.

Cheers guys. Here's every bit of information I can recollect
A few days ago I created a nandroid backup and formatted my sd card via the PC.
I flashed the latest version of CWM recovery
I flashed the virtuous infinity rom 1.33 alpha v3 and then flashed the 1.35 beta 1 update.
Then i copied some music on to the SD card and installed a couple of apps.... nothing out of the ordinary.
The phone worked fine the last couple of days but I don't remember letting the battery die all the way. I should add that I have a dodgy battery; a couple of months ago my dear girlfriend spilled her drink and beer went in to back of my phone... since then the keyboard doesn't work (some keys work but its basically dead) and the battery has been affected as well since it now only lasts 3-4 hours after a full charge....but this issue can't have caused the problem I'm now having because the dead keyboard and dodgy battery have been around for a few months...
Last night, however, I think I let the battery die all the way and at some point, when I tried to turn it on, the phone vibrated as it does when you hold the power button, however, the screen didn't turn on. Since then, nothing has changed. When I connect the phone to the PC, it makes a couple of "connection" noises but I can't access the SD card or contents.

by saying latest CWM is it the 6.0 touch based CWM by chance?

sorry mate, i meant 5..0.2.7.

That's the CWM I'm using so it's safe. I'm also on latest VI for weeks without problem.
So it all points out to your battery.
Phone vibrating to power button means it's responding perfectly. Not sure about the light on the sensor only htc technician can tell.
But what I can say is if your trackpad button lights out red always then you got a brick on your hand.

Nope the trackpad isn't red so I guess that's a good sign. I've ordered a new battery and should have it later this week. Let's see if that fixes the issue. Will report back. Thanks all!

So, a new battery has arrived, however, it hasn't helped as the phone won't charge (no orange light) or turn on...... Since I live in Australia, I don't know anyone else with this phone. Is there any other way for me to revive my brick of a phone?? Thanks

Get a universal charger for your battery.

This is a rough situation. Even with my DS I've had situations where nothing would happen when I tried to restart it, in particular when I let the system run all the way down. It is as if the battery needs to have some charge for it to charge more. I have three batteries though (the stock & two Anker 1900's) so when this happens I just swap out the battery with one that I charged in the external charger, and I haven't had any real issues with them long-term. Since you bought a battery, what battery was it, and do you think it was charged when you got it, and do you have an external charger to verify that the charge is solid when you put it back in the phone? Your phone may be completely dead however, but at this point, I don't think anybody on the thread really can tell. This make sense? I don't want to say, "buy a set of Anker 1900's with an external charger" but it was cheap enough vs. the cost of the phone, and the DS does seem to be a good one overall.

Hi All,
So I got an external charger for the battery and it arrived yesterday. I then proceeded to charge the battery and hours later, no luck. The phone still doesn't turn on. When I hit the power button, one of the sensors on the top left turns red slightly, shortly after which the phone vibrates. However, it doesn't turn on.
Where do I go from here?
Thanks

have you tried to disassemble your phone at all? you said liquid was spilled in it, could take time for corrosion to turn up. maybe a little electronic parts cleaner or rubbing alcohol may help out

Nope I haven't tried to disassemble it yet but is that the only option remaining? If yes, I might have to give it a go because this phone is now as useful to me as a brick, in its current state.

[Q] ipaq hx4700 replacement battery problems.

Does anyone know what to do when battery says its 0% charged even after it has been fully chaged(the charge led is solid)
I have this weird problem with 2000 mA replacement batteries for the hx4700 (The original one is 1800 mA).
The thing is that both replacement batteries now report 0% to the device even after they have been charged and the amber light comes solid, indicating that the battery is charged.
First battery "died" few monts ago about a week after I charged it for the first time, that happened the day after when I took it out so I can charge the old original one, the new battery had 75% left, so I didn't want to charge that one. The next day after I used up the old battery, (which is still working fine, except that it keeps dying on around 20% power left for years now, because the voltage drops under 3.5V) I replaced it with that new battery which was supposed to have 75% of power left, but it reported 0% so the device died, so I charged it over night, the amber light was solid, but the pocket pc went with critical battery level and CF/SD card removal bull**** and turned off shortly after that, since the circuit that is in the battery reports 0%, no matter what I do, I tried cleaning contacts, tightening the cover, took the battery apart and there was no visible damage and nothing. Then I throught it must be because I accidentaly dropped the battery on the floor (it didn't sound very good), so I just out that one aside and used the another battery.
I have used the another for about a month, charged it only when the battery was actually under 20% or dead, didn't even take it out. Today the battery reported 0% just like that another one and it was fully charged. Also I'm sure its the battery not the pocket pc, I have two hx4700 the old one I have been using for 6 years and the new one that I have just assembled with parts I bought from ipaq repair a month ago, the old battery still works fine and its reporting the charge correctly in both devices and the new ones are both charged, but reporting 0%.
I worked around this problem, by disabling this driver in registry HKLM\Drivers\BuiltIn\BatteryIF\Dll
I chaged the value from "battery.dll" to "battery.dllx" so the driver doesn't work and the battery levels are unknown to the device.
The battery runs fine for hours, like it did before, meaning there is nothing wrong with the battery cells, but with the little circuit, that is inside of the battery and that its annoying, because I don't know the level, can't tell when my ipaq will shut off.
Has this ever happened to anyone? Is there any way to get the battery to work again, without disabling the driver? Should I try replacing the cells of original battery with good cells from those bad batteries? I'm really frustrated how the original battery doesn't have the problem after many years of usage and the replacements have issues after few weeks!

My HTC One X Is Dead??

Hi dudes I have a big problem with my htc one x, my cell phone doesn't charge anything (the red led dont turn on and the charge dock doesnt get heat) It didn't crashed or something, it was with low battery and I took borrowed his charge dock (I was in his house), but it didn't charge anything, as I said my cell phone wasn't crashed or hitted by nothing, It just stopped charging, what can I do to revive it? Please help mee :crying::crying:

Did u let it fully die? Sometimes power cycling is not a good idea...shooot.. Doing it isn't good period. Let it stay in charger overnite.. What ROM you running ?

Yes the charge fully died, and turned off, I let it in the power plugged last night the whole night charging and nothing happend, It was working well untill I pluged it with my friend's charger, his charger is 5v 800mA, since I plugged it on, it stopped charging, that might damage my phone? I mean all chargers are the same but , seriously that charger could kill my phone? is weird

Not all chargers are the same. Have you tried using your own charger?

maybe once every 3 weeks or 1 month

Ok. I'd keep trying to charge the phone, but unfortunately this kind of thing does happen with electronic devices from time to time. There's no real way to say exactly what's happened but it's very possible you have a brick.
Sent from my Evita

the last 2 weeks my cellphone was automically rebooting, the bottons of the cell phone (back,home,and the other) start flashing and automatically rebooting, I don't know If that says something what do you think?

Could he possibly hold down vol and power..for a long time...maybe it could get to boot loader,,,,?

I tried but still dead x_x

Power cycling shouldnt bother a mobile phone battery to be fair, unless it's left in a low state for an extended period of time (8% discharge per month roughly) so it's a bit of a misnomer. Lithium batteries should never be fully discharged but as a safeguard you will find when the battery reaches 0% as displayed on the phone the battery is still more than halfway charged to prevent this kind of thing happening. (Most phones register 0% at 3v but the safety threshold is around 2.2v, absolute battery death is 1.5v. Bare in mind at full capacity a cell is 4.2v so your pretty safe when it gets to 0%)
What is more likely an issue is using a faulty charger, there are dozens of cheap chargers which will trash a battery. It is disgusting what gets through the borders from places like China, these things don't have adequate power regulation or filtering. At best you reduce the phone lifespan, at worst it burns the house down. Never ever use a charger than costs less than $15 as there's a reason, decent components cost money unfortunately..
Now, if the device won't charge (a usb 3 port on a pc is ideal as it provides a stable 5v at 900mA or more if a genuine HTC charger isn't available) or switch on you can try removing the battery (be careful as the HTC screen is delicate and there are special tools you need), there are guides on the net or if your not confident then take it to a service centre and they should replace it for you for a fee.. if you buy a new battery off eBay then don't bother with the high capacity as they're fakes, if HTC could cram extra mA into the same size they would - but it's against the laws of physics to get double capacity.
I'm sorry your phone appears dead. I hope it's just the battery, just be very wary about unbranded docks/chargers as they're evil.

Check the Charging port and switch the cable
Maybe the charging port is broken.
On the other side maybe the cable is broken did you try charging another divice with it?
The solution may be simpler than you think.

Friends when I plug in my htc one x to my computer, my computer made a sound, but it didn't detected my cell phone (just made a sound when you plug-in any divice), and my cell phone doesn't charge is there any I can do? Or is dead

You might be able to get a jtag repair done.
