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] 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] Battery Stuck at Zero Percent

I recently obtained the Xoom LTE version from a family member. It wasn't used in quite some time, so naturally, I plugged it in to charge. The indicator lit up white, so I turned it on. After boot, there was indication that the battery was charging, but remained at zero percent. I left it to charge for about 25 minutes and when I came back to it, still zero percent. I removed the charger, the device shut down immediately. I plugged the charger in again noticing that the indicator light did indeed light up, but after a short amount of time it turned off. I also tried using the dock, and the same results occurred.
Basically, the device is only operable while plugged it. It's been on the dock for a couple hours now and the battery is still showing zero percent. I'm thinking it's a battery problem, but what else could it be? Is it possible to change the battery in this thing, or do I need to send it into Motorola? I did a factory reset, but nothing has changed.
Thanks for any help, I really appreciate it!

Best bet is to send it in for a new battery. Sounds like the current one is shot.

Yep usually Li-ion battery does that, you said they haven't used it for months? My bet is that the battery is fine, but it's dead due to the fact it went under the level of voltage where it can't be recharged. It's like bricking your phone... Lol

Definitely sounds like a bad battery.
You can try to order one online and replace it on your own (here is ifixit's teardown guide).
Or you can send it in the Motorola and have them do it for $99. If you've never opened up a tablet/phone/etc before, I'd highly recommend this route. It might look easy but I totally borked an old phone thinking I was handier than I actually am...
Your battery is covered by your warranty if its fully charged capacity falls below 50% of rated capacity in the first year of ownership. Out of warranty replacement of the battery (OOW due to the length of ownership or physical abuse) is $99.

Nexus 5 not charging/charging slowly

I was wondering whether anyone else is having issues with their Nexus 5 not charging, or at the very least charging super slowly?
Mine has been plugged in for about 3 hours and only charged up about 10%. Could it be a teething issue (it's the first charge out of the box) or something worth contacting Google about?
Any input would be gratefully received.

Yeah, I've rebooted a few times as I've been installing odds and bods and getting it how I like it.
I plugged it in with a different charger which took it up to 100% in about an hour, but after unplugging it and using it for about 45mins it's dropped like 35-40% - and that isn't media consumption, that's just settings, web, etc. I'm not sure whether its me or the phone!

Definitely the phone. But I can't figure out exactly what.
The drop to 40% could some from brightness, data, you using and playing with it. In that case, the charger is broken, and needs sending back.

When it's charging go to settings > battery and see what it says at the top next to the word charging.
If it says (AC) then it should be going up around 1% or so every minute, if it says (USB) then it will be anything from 1% every 3 or 4 minutes to every 15 minutes. If you're using the stock charger (plugged into wall socket) it should always say (AC), if it says (USB) then something is wrong.

I'll keep an eye on it over the next 12-24 and see if I can isolate what's responsible. It's an odd one though, for sure.

Glad it's not just me experiencing this. I noticed yesterday that when I took my new Nexus 5 out of the box and plugged into my computer's USB port to charge it the phone's battery percentage was rising painfully slowly, and the percentage wouldn't budge at all when the screen was on.
I charged it to 100% over night using the supplied charger. Drove to work this morning with it plugged into the USB port on my car stereo, and unlike my Nexus 4 which would usually be on 100% by the time I get out of the car, the Nexus 5 was on 94%.
I've been at work for an one hour and 20 minutes now, and whilst my nexus 5 was sitting in my pocket doing seemingly nothing it has dropped from 94% to 80% battery. At this rate it will be on red before I leave work, and even sooner than that if I have to actually use it.
BetterBatteryStats doesn't work with Kit Kat yet so I'm unable to gain any further clues... Will be interested to hear what happens with your Nexus 5.

I've been keeping my eye on it and it seems that Google Services is using the most battery, 24% at present, and my screen - which I would expect to be sapping it the most - is only at 9%.
That said, I charged it up to 100% last night and left it and it was at 91% by morning without being used at all. By lunchtime it was down to 73%, again, without any use save for half a dozen text messages sent.
It's not terribly impressive so far, it has to be said. I'm hoping it's just a painful breaking in process rather than an RMA issue, because Google offers shocking after sales service.

You don't need to RMA. It's the software's fault. Maybe the fact that Google Now listens to you continuously when you're on your homescreen has something to do with it.

Sounds like the phone is performing some sort of heavy background task? Maybe backing up your app settings?

Mine also seems to be discharging very quickly and charging very slowly. It charged the same way on a few different chargers. My SIII can usually go from 10->80 in like 30 minutes...

The always listening thing doesn't seem to be activated on mine (it's a UK model), but I've been surprised by the drain when it's on standby, without even being touched. I'm used to battery life being a bit iffy, as I've come to this from a Nexus 4, but I was expecting a little bit more so far.
I've tried factory resetting in the hope that it might iron-out any potential software issue, so I'll keep tabs on it today and see how it progresses. Fingers crossed, eh?!
Cheers for the continued input folks.

I thought I was the only experiencing this issue it takes awhile to charge and battery drains very quickly. Last night battery was down to 20% this morning woke up and found battery was completely dead, not impressed at all. My biggest concern here after using note 3 for the last month this is very worrying indeed.
Mine is also from the uk.

I think this is definitely a Play Services issue.
When I checked my phone late last night I noticed that Google had forwarded a Play Services update to the Play Store. I've been playing with my phone this morning and battery seems hugely improved. Watched YouTube videos for 45-50 minutes and the battery dropped from 100% to 91%, which would suggest a potential screen-on time of around 8 hours and 20 minutes in total. Not bad.
I've had my phone in my pocket for 30 minutes and the battery hasn't budged from 91%, which is again good news. Yesterday it was dropping 1% every 5 or 6 minutes.
It will be interesting to see how it holds up when I stream my Google Play Music library in the car on the way to work, or how it is when I get to my office where the signal is horrible. "Play Services" battery consumption was high on my device yesterday but"mobile standby" was just as bad. Will report back later.

Change your google now voice setting to US English and the hotword box should appear when you back out and go back in.

I have a slightly different issue. My Nexus 5 ONLY charges at USB mode with any other charger than the one supplied. I've tried 5 chargers including the car charger and BB PlayBook high-speed charger. I've also tries using the supplied USB cable with another charger but it's a slow-go.
Very disappointed. May have to RMA because my buddy's phone does not show this problem.

@riz157
In my experience Google Play customer services has been bloody awful. Got dicked around on a simple RMA request (the screen on my N4 went nuts spontaneously) and received no updates or anything. Every time I wrote to them I got told "We're waiting for a specialist to deal with this". It ended up going on for over a month before I said "Sod it" and just sent it to LG. Who, it has to be said, returned it as 'repaired' without even looking at it, leaving the problem still present. Had to just pay the extra out and get a door-to-door replacement from Google in the end, which I wanted to avoid.
In re the problem, have you had the Google Play Services update that @Stylus_XL mentioned? I haven't yet, I don't think. My battery is still draining too fast. I haven't touched the phone for hours, then picked it up and made one 2 minute phone call and it dropped 4%. Stylus, is yours still stable after the update or have you seen any other issues?

My first battery cycle was weird. Took a few hours to reach full, behaved normal on the way down. Second charge from about 40% took about 90 minutes to reach full. It may just be the first cycle or two.

Use original charger.

Oneplus One Battery discharge even when completely switched off

From past 1 month I'm having a hard time with my 1+1, I started experience heavy battery drain during stand by around 35-45% over night (aprox7-8hrs) I thought the battery has come to end of its life so I ordered a new battery for 1+1 and replaced it myself. But guess what I'm still facing the same issue overnight the battery drains 35-45% even when the phone is completely turned off. What's happening I don't really understand. I also tried charging the battery to 100% and removed it from 1+1 and left it for a day and when I popped it back in it was holding the battery very well it was 99%. It is only draining when I connect it to the phone the battery starts draining again. Is there anybody who can help me with this issue.? I really like this phone that I don't want to buy any other phone right now.

Ya but I cant I purchased it last year around June even before it was launched in my Country. So have to try to fix it myself

Hey hello..
I pity you.. Btw even I have similar problem.. I know how it feels.. The battery used to last 2 days easily and now merely pulls a day.. Same 35% battery drop even when I have it switched off.. I have tried almost all ROM's in vain.. Only thing I can tel you is, try charging the phone overnight and discharge completely before charging it again.. repeat this for 3 to 4 times.. This trick worked out of nowhere for me.. But again now after 10 days, it has gone to the state of not holding juice longer.. I am at a loss to understand what is wrong..
PS.. Do lemme know if you find a way out of this..
