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:
http://www.facebook.com/group.php?gid=100925126406
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

[Q] Battery recalibration issues - G1 on CM 5.0.8

My apologies if I am here with the same complaint, but I tried searching this forum and found nothing that works for me.
Basically, I rooted and flashed CM 5.0.8 and I have been having battery issues. Now its not that my device is draining battery at a very fast rate (seems it is indeed doing that), but I suspect there is some problem with the battery meter.
So from all the stuff that I read, I decided to recalibrate the battery. I charged it up to full, until the green light went off, until the status showed 100%(full) and then some more. I then restarted into recovery(Amon-RA 1.7.0) and wiped the battery stats and rebooted back into CM, while having the charger connected at all times. Its worth noting however that during the time the phone was booting itself into recovery or into the ROM itself, the charging indicator stayed off. Thanks to that, when the phone booted into CM, the indicator was red for a few mins before it turned green (charge had dropped 99%)
Now I've done this 2-3 times, including letting the phone die due to an empty battery, but I am still getting very little life from the phone. For the record, I have the end button set to sleep and I don't have any continuously running widgets and my syncing apps (twitter) are set to sync only every 1 hour.
Anyway, again I don't think these apps are draining much battery, since once the battery dies down and the phone switches off (after light to moderate usage as compared to the life 1.6 Donut gave me), when I put it back to charge and turn the phone on after 5-10 mins of charge (while the phone is off), the meter shows a charge level of around 65%. So I suspect that the battery charge is at around 50-60% during when the meter reads it as around 1% and forces the phone to turn off.
I also tried switching on the phone after it had turned off, but it switches off immediately after booting (at least on 1.6, I could reboot it a couple of time on a 'dead' battery)
Are there any other tips that I can use to recalib my battery? Any idea will be much appreciated as my phone dies out each day before I can get back home and put it on the plug. Should I consider upgrading to CM6-RC1? Has it been proven that the battery performance is better on that?

Have u tried swapping out the battery with another one to isolate it to possibly the battery itself? Isolation is key, that way could it be ur extusb isn't charging correctly or is it the battery?

Well, I do have a spare - the one I saved from my bricked G1, but I haven't tried it out yet. The battery was working perfectly well just a few days ago when I had a stock Donut. So, I suppose it isn't a battery problem, but no harm in trying out the other one.

i had issues with my lithion battery and found out it happened to be on its last breathe. And with my spare i had it worked good. did u drop the battery at all? with lithium ion batteries can be as delicate as expensive china or porcelain. And to be honest the batteries that came with our g1's aren't really that good. If you can I would suggest getting an ext. battery from ebay. ive heard that fully discharging a lithion battery isn't the best practice either. I'm no expert just experience Best of Luck!

well...
reading the Cyanogen 5 thread I noticed at least 5 people with a broken battery...
for the record mine is broken too...
it's all swollen up... I mean, I can use it but it doesn't last a full day and it doesn't fit perfectly anymore in its slot inside the phone...
I'm starting to think that maybe for some reason flashing cyanogen 5 caused this issue, since so many people had this problem at the same time...
or maybe it's just a time defect of some stock htc batteries... who knows...

@GigiSpligi: Nono... don't blame CM for the swollen battery. Batteries tend to swell up after a lot of usage (charge discharge cycles). The battery on my old Nokia phone had swollen up after about 2 years of use. Similarly my friends E51 battery. Also my G1 batt seems to have swollen a little bit already. So nothing to do with the ROM.
Of course, if the ROM is making you charge frequently, then it is indirectly causing the effect on the battery.

The exact same thing happened to me ... actually on all ROMs now ... i'm gonna look into getting a new battery and sdcard which kinda sucks, but oh well. when i think about it, i wasn't have any problems till i started flashing sense based ROMs, especially Slide ROMs. so i must have done something wrong. i can't even make a phone call for longer than 10 mins before the phone shuts off and have to plug it back it into a charger just to get it to boot to the home screen
... hope there is a solution ... haven't read through this thread yet. just wanted to let you know you weren't the only one with the exact same problems

hahaaha well that didn't take long to read ... yeah my battery is somewhat swollen and i did drop the phone once ... time for a new battery i guess ... sucks

[x-posted from Cyanogenmod forums]
Ah well... gonna have to pull out a new battery and see if that helps in anyway. I will have a look at the device usage stats to see if anything is causing unnecessary drain. Since there has been a drastic change in the battery life after the upgrade, I do not want to blame the battery itself yet. Guess some app is driving the phone nuts.
Ok, I was just seeing the battery usage history in spare parts and I there are some interesting usage stats there.
Network usage - While Market, Android System, Google, Calendar are around 1% - .5%, almost 100% of the usage has come from Media. I think this has been trying to keep the network alive throughout the time. I dunno if network means Data or just the voice network. The packages listed under Media are Camera(twice), DRM, Download Manager, Media Storage. Is there any reported issues with Camera or Media Player?
Also, Spare Parts says my Battery Health is Good. Is this a reliable indicator of the battery life?

I believe spare parts receives the battery info via "Testing" which comes stock on android. Let me know how the new battery works out cuz I want to research further when it comes to phone environment versus the actual battery itself.

I have same problem with my battery. I guess maybe battery life since it already use 1 half year. Anyway, who knows.

new battery
just picked up a brand new battery today. gonna leave it charging overnight. will report later on whether it fixes the problem with the random shutdowns
... on a side note, i think there has been a battery issue since CM5 correct? in my sig there is a recalibration method by xda member 'my_former_self' for those who have not read it and if your battery is still good to go ... worth a try

new battery
so it turns out my battery issues was in fact the battery. the new battery is working awesome. phone hasn't randomly shutoff on me all day with heavy texting, some youtube vids, mild internet browsing, and several apps ... 17+ hours later about 2% charge remaining. gonna run the battery through its conditioning cycle.
fyi i turned airplane mode on when i was in class ... approximately 2 hours

New battery it is
After spending over 4-5 days with the battery, I pulled out the spare that I had (with a couple weeks of usage) and installed that on my phone. Just to be safe, I drained the battery after some initial charging and ran it through this battery recalib method.
I did this yesterday morning after it being charged fully. I also installed SetCPU after recalibrating. Its run 2 full days of regular usage and I still have over 50% charge left. Ain't that cool or what? I think I will leave it uncharged tonight also and I guess it should last the whole of tomorrow as well. I don't think even the stock cupcake or donut lasted this long on a single charge. So in that case CM 5.0.8 has actually managed to up the battery life a lot (with SetCPU and, sleep on end).

Exactly how long does your battery last? It's no secret that CM5 (and any Eclair ROM) is just plain poor on battery life in these devices, even on my in-warranty Magic it chews through the battery about 25% faster than any Donut ROM such as Dwang, SuperD or CM4.
Seido sell extended batteries which fit in the original phone housing (unlike those ridiculous ones on eBay which have an extended back and turn your phone into a 2001-era brick), they seem to get good reviews, maybe give one of them a go.

[Q] Sudden Unexplained Increase in Battery Drain

Stock 2.3.6 with no changes to or updates in settings or installed software and I have been taking pretty good care of the battery in a 5 ½ month old Atrix 2 directly from Motorola and not previously used.
Several days ago battery drain when in standby when from approximately 0.5% per hour to 2.5 to 3% per hour. I did the following, although not necessarily in the order listed:
Bench tested battery at a battery shop – no problem found.
Verified settings and software. Cannot find anything that appears to be draining power, initiating communications, etc.
Pulled battery.
Hard data reset and tested drain rate with no additional software and had same problem as when normal software was installed.
Several deep cycles from 3% or less to full charge. In all cases mV appear in normal range of about 3542 mV at 3% to 4347 mV at 100%, again per Circle Battery Widget.
Broke down and called Motorola and although they tried to be more helpful than normal, the only suggestion that they could offer was to try another battery, which I do not currently possess and AT&T would not allow a short term lending even had they had one available.
99% of all charging is via stock wall charger, spot use of car adapter with appropriate specs when using GPS.
Typically recharge starting in range of 5-15% and charge to 100% as indicated by Circle Battery Widget.
Battery usage in standby shows about an even split between Cell Standby, Phone Idle and Bluetooth each about 32% of usage when in standby. Have always left Bluetooth on 24/7 except when charging and battery drain was only about 0.5% per hour. I even tested for several hours with bluetooth off and this did not affect the rapid drain.
Contacts are clean.
I even use Motorola USB cables both from my PC for data transfer and also with the wall charger.
No exposure to excessive heat/cold.
If anyone has any thoughts, I would greatly appreciate any help. Otherwise my next steps are to call Motorola back Sunday morning (U.S. time zones) and probably order an OEM battery from a reputable source allowing for U.S. holiday on Monday. Unsure how Motorola will treat this as warranty since 1) this phone is a replacement for Atrix 4G problems whose warranty would be expired, and, 2) batteries have weak warranty coverage anyway since so much of that is beyond their control.
Thanks

Same here recently.
My battery life has gotten a lot shorter (and cell reception worse). Most of my 'battery usage' is coming from cell stand-by.

Overcharged Battery
How long are you leaving the A2 on the charger? MTL you may have "overcharged" the battery, overloading the memory in the battery itself, therefore resulting in less usage time from a "fully charged" battery.
Typically, as a sales rep, I recommend my customers only charge their phone for the full 4-8 hours, when it is the FIRST time they charge their phone. typically after that, it takes only 2-2.5 hours to provide the phone with a full charge. Over charging will fry the memory and make the battery hold less charge and over a period of time eventually kill the battery, making you have to buy a new one.
P.S. If I am completely off base please let me know. Yes I am noob, but this info was actually part of my training courses so I'd love to tell them they're wrong. Hope I was helpful.

The phone electronics will not actually allow overcharging. you will have problems if you do overcharge it but you can't do that while it is in the phone.

Thanks but in addition to any designed protection against overcharging I also pull the phone off the charger as soon as practicable after hitting 100% per Circle Battery with the exception being when using GPS which means that the phone will charge very slowly to 100% and remain connected to the charger until the next stop in my trip. The phone charges more slowly on the car adapter because the screen is constantly on along with running GPS and music software and streaming music via bluetooth.
I also try to make sure that I always disconnect the charger before starting or turning off the vehicle's engine. It may not be necessary anymore but that is an old habit.

Happening to me recently, before the battery lasted very long, but the past few days I arrive at night with 20% left. I tried doing a factory reset but it still the same. Also, the "cell standby" is the biggest consumer? I don't know what does that mean...

As far as I know 'cell standby' is basically your phone searching for a signal.

Remove any app that u suspect. If u have installed battery indicator pro, that's the culprit. Same happened to my phone when i had battery indicator pro. Install juice defender ultimate. Works a bit. Clear off d ram and reboot

For what little it may be worth replacing the battery showed the same problem and motorola now admits that this might be a motherboard issue and wants me to send the device to them for repair. They had their level 3 contract tech support review what I had done for troubleshooting and they agreed that the above steps plus replacing the battery had exhausted all possible options that can be taken outside a repair depot.
Those with similar problems may want to do the same and finally call motorola.

Wonderful, I am on my 3rd Atrix 2. Returned two previous because of the sd card reader/compatibility problems. The third one I received hasn't had the problem but now I can't go more than 8 hours without the battery going dead.
Cell standby is normally over 33% and Phone idle is normally at 30% or higher.
This happens whether I leave wifi on all day or turn it off.
Stock 2.3.6
I work from home and I have 5 bar signal strength from my house so there is no reason for my phone to constantly be searching for network signal.

Still happening to me. Today I was talking with an AT&T representative via online chat, and they only tell you to disable background data, and set it to super saver mode. They didn't want to listen that the phone before lasted until midnight with the battery still green and that now it goes red. The guy said that the phone is supposed to last 8.5 hours, since that is the talk time. I tried to explain that the talk time didn't work like that, but no good.
Finally, I went to an AT&T store and inquired about the issue. Since I'm within the 1 year warranty they are going to send me a new battery. If that doesn't fix the problem they said they would change my phone.

[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!

Battery problems

I own an Orange Neva 80(rebranded ZTE Blade v7) and I recently started having some battery problems. Just 2 days ago I was stunned by the fact that it took about 2 hours for my phone to go from 90%+ to 0%, which is an unusually short amount of time. The top part of the back of the phone also seems to heat up pretty easily. I downloaded some battery apps from the store and I noticed that when my battery level is about 90% the app says my battery only stored about 1000mAh, so less than half of its maximum capacity which is 2500mAh. The phone is only 1 year old and I expected the battery to last longer than this. Is replacing the battery the only option or can something be done to save the current one?

- Smartphone batteries are usually designed to last for about an year or year and a half; specifically speaking, that is around 300-500 charging cycles. However, majorly depending on your charging habits, your battery can have more than 300-500 charging cycles lifespan. Meaning, every time you plug in your phone to charge, it uses up a charge cycle.
Answering your question -
Before you purchase a new battery, find out why your battery is draining rapidly (Besides the fact that it is operating passed its charging cycles capacity):
