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
Hello,
anyone have solution for Uni Battery
My Uni is getting Turn off when battery power is 66%,
I tried the procedure defind in wiki page, but still same
Regards
Sorry man but no help for your battery
I have same problem and tray everything possible and impossible but nothing help
Best solution is to charging your battery in AC charger not on usb PC connector
cheers

Or buy a new battery...
I had this problem, but my solution was a tad risky.
Try discharging the battery COMPLETELY, so letting the Universal die at 66%, then trying to turning it on after that until it simply will not turn on anymore. When you get to that stage, take your A/C charger and plug it into the Universal, allowing it to charge for 9-12hrs (overnight is good). Once it's fully charged (green light where the orange once was) take it off charge and see if that 66% goes any lower. Mine goes to about 12% before it dies now, which is a good day and a bit of charge for me on the stock battery. Not bad, considering I top it up everynight anyway.
The reason it is risky is because I've heard the batteries the Universal use don't like being completely discharged. Not sure on the technical reasons why, they just don't. So I'd consult another before trying this.
go universal's wiki and read the how to fix battery issues!
you may need to recallibrate your battery!
if you update your latest rom, with the battery not fully charged, you need to charge the battery to 100% and flash again you rom....
solution
dont mess! for the cost, buy a new battery. Batteries do wear out. If it is a fake one, they wear out even quicker.
Had the same problem myself, tried loads of stuff. In the end I also bought a new battery.
One thing you could do, is run your uni with out your SD card.
Thanx to you all for replying,
I think new battery suggestion is good, instead of taking nay risk.

Hi,
I didn't know what happened.. what My Sensation now take about 6 to 7 hours to complete from 15% to 100% while before i just took 3 hours to complete the charging...
Edit: I knew the reason .. I used Nokia charger and it take more time (double) than the Original HTC charger.. i think mainly because of the charger...
possibly bad hardware, or a ****ty battery, i get full charge from 2% to 100% in about 3 hrs
I had the same problem, sometimes it goes fast, other times it just takes ages, aslo got the non responsive touch screen issue oh, and gps won't fix, it cant find more than 5 sattelites, hurray!
I'm getting this on mains charging now also.
Not sure why - has anyone tried a "power off" charge versus a "power on" charge?
I always charge my phone power off. light to moderate use I get at least a day before charging.
Maybe that's firmware dependent. Some ppl noticed the same but after updating from 1.28.xxx.x to 1.35.xxx.x battery performance, battery monitor behavio(u)r and charging time are improved as well as other bugs fixed. But it's not officially released yet.
HTH
I'm using the 1.35.401 update, and still have this problem, aswell as bad gps reception, high battery drain, and long charge time.
im rocking 1.29.531.2 stock for my fone, and no problems with the battery at all, quick charges, and good to great battery life.
as for the GPS, i think everyone is having that issue right now, the most i ever got was on a completely clear day, 7 satellites :/
my HD2 after running the canada fix thru CWM got a minimum of 12 or a clear day
lucky for me i dont use the GPS that often, if ever
EDIT: also, im using the stock charger about 3 out of 4 of my charges, the rest are from my lappy via usb
It's slow at charging. Get the wall charger from tmobile or use a Samsung galaxy s charger. The galaxy s charger will charge it way faster than the stock htc charger.

I can honestly say that it takes mine about an hour longer to charger while power off than while power is on, don't know y tho. So now I usually just let it drain to about 3% n then charge it..

If you want your battery to last longer you shouldn't let it drain more than down to 20%, due to the nature of the lithium battery

Any proof/literature on this or this is just what u do n u feel like it helps
Sent from my HTC Sensation 4G using XDA Premium App
its actually a fact, most ppl who have used Li-Ion for at least the past decade know that if you want the best performance, dont let it drop below 15-20% before charging, for optimum batter life and sustainablilty.
same thing goes for if you arent going to use the device for a long time (min. 1 month) charge it to around 50%, then decomission, and the battery will "keep" very well
EDIT: because flamers love their link complaints http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
with 1.35 chargin is much faster. really it's already available ota for unbranded, branded phone owners need to w8 for their carrier ... :\

i'm interesting by your proposition,could you explain why galaxy s charger is faster than htc charger?
i use to wait 3 hours(-+) for 25 to 100 pcent, how galaxy s charger is faster?
thank you!

It charges faster because it charges faster. Lol
Idk why it does, but it does. It's the same for my hd2. A friend gave me the galaxy charger for a extra. I tried the charget and it just charged faster for my hd2. So when I got my sensation and saw that the stock charger was slow like the hd2, I tried the galaxy one, sure enough, it was faster too.
Thanks for your informations...
Just got 1.35.163.1
Some people says that improve the charging time.
I will report this tomorrow.
And i will test with sgs charger too!
I have a US version stock. As you know we have no updates yet and no s-off. My phone charges fast sometimes, other times it can be on the wall charger for 6+ hours and not be fully charged. I think its a software issue honestly.
Yes as said earlier recharge when it's at 20% the battery will hold much longer the batteryuniversity is my source too Also spare batteries should be kept at 50% and kept in the refrigerator when not in use.
Hmm the new update didn't do much for charge time for me though.
the charger that comes with the sensation is ~1A which is kinda slow when the phone is on, not as bad as others with only 500mA usb... you should be able to find a usb that give a higher A output and still retain the usb plug (ive seen 1.5A before cant remember where)... failing that if your ingenious you can splice through a different charger and make your own.. could achieve 2A+ but your could burn ya house down or blow your battery up in the process
Ok so I'm not sure which it is but I'm thinking / hoping it's only my battery here's my issue. My phone will not charge properly. It'll say it's at full charge but soon turn off and act like the batteries dead.
Other times it'll take forever to charge even when I leave it charging and don't mess with it. I also rebooted into recovery one day and I saw a message saying my battery voltage was too low.
I did drop it when it was connected so I'm also thinking maybe my USB connector isn't allowing enough power to the battery anymore. Just curious if anyone knows the issue so I have an idea, for how much it'll cost me to fix.

Buy a new battery. They cost around 20 bucks or so, Anker preferably.

Yeah, it's better you buy a new battery. :/
Hi i bought a used sensation of ebay from a reputable seller and it arrived the other day. The two main problems i've been having is also the battery taking long to charge and the heating issue.
Firstly im not sure if the heating issue occurs on stock rom as i was not on it very long but on any custom JB rom the Bottom part of the phone gets very hot very quickly. I used a battery monitor and it tells me its the battery temp that's going up but when i pop out the back cover it seems to be coming from right at the bottom under where the micro sd card is. However i think i have kind of solved this by flashing the Inspiration 1.01 ICS 4.04 rom with bricked Kernel. Now the phone only reaches a max of abut 40.5 degrees and the heat is spread around the whole back case rather than one spot.
Secondly the battery seems to be the big problem here. The phone didnt come with a charger but it did come with a USB cable to charge with. The problem is when i plug it into charge it takes long time to charge up. I used a battery monitoring app and the results are quite weird. When i plug it into charge it starts of drawing about 300ma of charge but after a while especially when it gets to around 30% battery the amount of power the battery is absorbing is around 70ma some times even as low as 40.
I have tried this with a Motorola charger as-well which is from a Motorola defy mini which had a higher Mah battery and the same thing happens.
Bearing in mind its a used phone the battery is probably quite old shall i try my luck with a new official replacement HTC battery or shall i try a new HTC Charger first?
Quick Update:
i took out the battery and then put it back in again and turned on the device and now the phone is reporting 65% when it was only at 47% before i turned it off. Secondly onthe battery contacts there seems to be a darker colour of gold where the pins actually meet which looks like a burnt contact but im not too sure.
I highly suggest you buy an Anker battery instead of HTC official one. If you've been loading battery with USB cable from another device (PC for example); it will load slowly!
About the battery percentage problem; I think this is a known problem on HTC Devices. It should show pretty accurately after a little while after restart.
I myself have the original battery, and I have the darker marks there too. Don't worry about those.. Because all you need is the Anker 1900mAh.
Thanks for your suggestion i have done a bit of research on the anker battery and it definitely seems like a must have not only for the better battery life but it apparently runs alot cooler than the stock battery aswell. Only £21 for a pack of 2 and a travel charger on amazon aswell!
Also shall i get a HTC charger or should i be fine with the Anker travel charger?

I don't know, but I am pretty sure both chargers will be just fine.
Awesome ordered one now should be here in a few days! Thanks for your help
