I have decided to move this post from the issues thread to a dedicated one to give it better visibility. If no one else is getting this problem then I will probably return the device.
I have the excellent "devstate" today plugin application installed which gives the battery charge level in 1% steps. When I say slow, it takes around 3 mins to increase by 1% which means it will take 4 hours for 80% charge (too long) when this is the case, the back doesn't heat up.
I have seen it charge much faster on one occasion i.e. around 1% a minute and the back was warming up (this is logical if more current is flowing) I was wondering the cause of the slow charge is that the device thinks it is connected to a pc and the charging current is limited. Also when you plug the cable sometimes the menu pops up asking whether you want to enter activesync/disk drive mode but doesn't on other occasions. There doesn't seem to be any pattern to it.
Another observation is that a soft reeboot occasionaly gives wildly varying battery levels for example before reboot the charge might be 100% and straight after the reboot 90%, or 83% before and 100% after. Interestingly before turning on the device for the first time I fully charged the battery, but up on boot up it was reporting 60%! (maybe it didn't charge at all when it was switched off and 60% was the initial amount of charge the battery came with) Have I got a duff battery or some issue with the device itself?
I seems like the battery charges fast up to 75% at around 1% a minute but then slows down to 1% every 3 to 4 minutes. Maybe this is the charging profile for this battery. Has anyone else noticed this?
Here are a couple of threads from the diamond section regarding the sort of issues I am experiencing but there doesn't seem to be a conclusive fix.

Could people please answer the following questions to help me decide whether I have a faulty device/battery or some ROM issue which all of us have. I have the stock UK touch pro ROM 1.90.405.1 WWE.
1) If you fully charged the battery before powering on for the first time, what was you battery charge level immediately after power on?
2) Have you noticed fluctuating charging rates?
3) Soft reboot gives different battery charge levels.
Just a quick Q, which charger are you using? Can you just post the amp / volt data printed onto it for us?
I am using the one that came with the touch pro, model no TC P300, its output rating is 5V at 1A. Input rating 100-240V
I have also tried the mda vario III charger and I get similar results i.e. fast charge up to 75% then slow afterwards.
As i stated in the other tread with the "Raphael issues" i have the same problem.
When i use the shiny new charger with the "usb-mini usb" cable i takes 7-8 hours to completely charge the device. (output is 5V-1A)
However, when i use my good old Hermes charger, or any other 5V-1A charger, it goes to 100% in about 3 hours.
Mine charges up to 90% from 10% in less than 3 hours after which it stays @ 90% (According to the built in battery meter of the device) forever. Is it a faulty battery or its supposed to be like that?

And do you get varying battery levels on soft reboot?
3 hours is probably what I would get i.e. "75% at 1% a minute = 75 mins" PLUS "25% at 1% every 4 mins = 100 mins" giving a total of 175 mins.
question is that is this behaviour normal for touch pro or only present on
some device/battery/chargers.
I also have another issue, this time regarding interference on speaker, see this thread:
http://forum.xda-developers.com/showthread.php?t=419761
If only my touch pro has these faults then I want to replace it asap, especially when having paid £500 for it.

Yes i do get varying levels on reboot, but i got that with my Hermes and Magician too. So i wouldn't worry about it. Usually when you softreset while it's charging you get a higher battery reading then you should have, but it wil drop after some time to it's real level.

This happens when its not charging. I don't get this with the vario III. Maybe it is ROM dependant. The other concern was after having charged the device fully when switched off, it reported 60% on power up. I might let the battery drain to a low level then charge when switched off to see whether it charges at all. Some diamond owners were also reporting this.
Hmm, got the same thing tonight with my Hermes charger, has been charging for 6 hours and still not fully charged, now at about 80%. Very strange. Are there more people experiencing this?

This didn't appear to happen to me on the first charge, but I turned it on immediately after putting the battery and SIM in place, and then I charged (I don't remember what the initial battery charge was). I've not noticed such wildly inaccurate readings after reboot either. I haven't specifically checked for inaccuracy in the battery meter, but I would (probably) have noticed such a big difference.
Have you tried to do a full discharge and charge cycle? This is necessary after around every 30th charge to recalibrate the gauge so that it is as accurate as possible. I know yours probably haven't gone through 30 charges yet, but it may be worth trying.

This is normal for lithium-ion batteries. The last 20% or so can take as long as the first 80% to charge.

When charging I usually leave mine overnight, so I think I've only charged it once during the day, and then I think this was through USB while connected to the PC so it may have been a bit longer than 'normal' (3-4 hours) for that reason. I'll keep an eye at it next time I do it during the day.
Six hours plus sounds far too long though, do you have a chance of trying the battery in another device, or another battery in your device?

Nope, don't have a second Touch Pro around here, but this is really annoying, I need a fully charged battery in the morning. If this is hardware related i'd return it to get a replacement.
hmm, this is interesting.....so just to clarify we are seeing slower charging with the bundled adapter: which is essentially an AC to USB power transformer?? If the USB port on that (yes i know its power only) is capable of supplying only a standard ammount of juice then your battery may charge to 100% as slowly as from a pc or car charger..
..id like to perhaps see if i can meter the current and voltage coming from it but would need me to cobble together a breadboard with the relevent power points.
Is the hermes / kaiser charger charging it fully in less time?? (to clarify)

Yes I drained the battery till the phone switched off by itself but still have this problem. I suspect there is a problem either with the phone itself or the battery as supposed to a ROM issue. I thought all the clever charging circuit is in the battery these days and it's the battery which reports it's charge level to the device too. If this is true then probably the battery is faulty but I am not going to buy another one just to find out. I'll try to get a replacement for the touch pro tomorrow when the shops open.

It is, but even so the gauge (in the battery) needs recalibration once in a while, hence the full discharge/charge cycle every 30th charge or so (other than that it is recommended to charge li-ion batteries often, and not deplete them fully).
Your next port of call is probably to see if another battery makes a difference.

Today I charged my phone from empty to full while connected to the PC, which took around 3 hours 30 minutes (phone not used except to check charge levels towards the end).
the charging cycle on mine has been a little erratic too.
I put it on charge at 9pm last night, at 6.30 this morning it was at 88%. 9 hours and not fully charged!!...still, 3 hours later and it's on 87%. so I think its more a case of requiring a few charge/discharge cycels to settle the guage down a bit.
This night it fully charged in 5 hours. While yesterday it wasn't completely charged in over 8 hours. There doesn't seem to be a pattern in this.
Yesterday it was showing 48% battery level at one time, a soft reset later 28%, another soft reset and it was 24%. Today I have sent it back for a replacement. Can those people affected by this issue please state where they bought it from, in order to figure out whether it might be a faulty batch. I bought mine from clove technology in the UK.

Mine came from Expansys.be, please let us know your new unit has the same behaviour.
Will do if I get a replacement one, they have satisfy themselves that there is fault first. Will probably take around 3 days. I miss my touch pro already.....
Oh well back to the vario III for the time being, seems cumbersome already in comparison.

Whilst I don't have any exact figures to hand, my hermes charger took about 45 mins (Give or take a little.)
I've been using the standard Raphael charger today and charged from 50% and it's still going after 1 hour 20 mins and only at 90%
I know the final 80% takes a lot longer, but even so.....

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
just wondering how long other peoples phones are taking to charge? mine seems to be taking unusually long im at about 2.5 to 3 hours and still at 87%?
It should take some hours to charge. Mine never seems to go over 500mA/Hr charge rate. So, if you have a 1500mA/Hr battery, the FASTEST possible would be 3 hours. (1500mA/500mA)
Now, the charge circuit will not charge at the max the whole time, so it should take longer than 3 hours. This assumes your max charge current is less than 500mA.

it was stuck in the 80% range for several hours so i thought i would try rebooting the phone... upon reboot, it was magically at 100% even though it said 87% before i shut the phone down and pulled out the charger cable... I have been reading another thread in the Q & A about other people having this issue especially when the phone is new... could have something to do with the battery calibration since it has only gone through one charge cycle so far so maybe it was confused about what "100%" voltages were... http://forum.xda-developers.com/showthread.php?t=1201474&highlight=battery is the thread where my exact problems are described

After first full charge, run it down to 2% like it also recommends. Help to condition battery, I do it to mine once in a while. Have this one for almost a year now and it is working quite well, can't say there has been any depreciation to run time yet.
Which app is this ??

That is correct,
I may be mistaken as I don't have the little instruction sheet., but there is some additional time in hours after the phone says it has reached 100% full charge that it needs to remain connected to finish "topping" of the battery. Although I would argue that it is almost impossible, given that any algorithm the phone uses to charge one brand of lithium battery vs. another hasn't changed when the battery has been swapped out, and charging should stop once the phone see the correct internal voltage. Yet ZeroLemom recommends to leave it to charge.
The final ~10% is quite misleading as far as how long it will stay on before it finally turns off due to low voltage cut out. I had mine running for over a day and a half sometimes before it finally turns off. Very annoying that low battery message, would have liked to know a way to change the notification, or either actually entering a new mAh rating in the ROM's data so a more accurate approximation of useful charge still remaining can be properly calculated/displayed.

Hey so I got it last 2 days ago and it on its way to its first discharge now. Should I fully let the battery drain to 0% or just charge it when it hits 1%? What would you do?
It's really up to you, I would at least reach the 2%. Any further past that point may or may not matter. I've let it go before until it turns off on its own, but like I said in a previous post the low battery warnings drove me nuts.

Question
I have the 8500 mah one, but in my phonr settings s5 G900F running sixperience 7.1 and it still shows like 2300 size in settings.. is that a problem or?
in the last week my battery no longer "quick charges". i have 'Ampere' installed so i'm used too seeing it charge at around 2800mA. i vaguely understand that phones charge quicker up to around 80% and then at a slower rate for the remaining - it's not this.
when I plug in the, current starts at ~1300mA and climbs to just under 3000mA... and drops to ~440mA in a minute or so.
it doesn't appear to be the cable and/or charging block that came with the phone - using a 1A charger from my last phone gets similar results and i purchased a new cable that's compatible with high speed charging.
i really wanted to love this phone.
I have a Samsung quick Charger from a Note5, and it has never quick charged my PureXL (actually super slow charges it,) but after the last update, I noticed I got an overvoltage error using it....
The reason is that this phone is not quick charge enabled. That's actually something that needs to be built into the SoC + Kernel support. You have a solid 2A charger, it'll go fast, but it can't rapid draw like say, the premium motos or a OnePlus.

sorry, i don't think i explained myself that well. i'm pretty sure that i've noticed a change in performance. when the phone was new i remember the current being high when battery % was lower, and then decreasing as it charged.
in the last week or so it seems to be charging at a slower rate and with the original 2A charger and cable. if the battery is at 20% the current will increase quickly to something above 2800mA and then immediately decrease so that by the time it's at say 22% charged the current is at a steady 440mA.
oh! ****. i didn't realize that 'quick charge' was actually 'Quick Charge™ by Qualcomm®'.. nice and generic sounding.
my pure xl was doing a full charge in less than 3 hours. as of last week all of a sudden it takes 10 hours to fully charge. using original charger and cable. can anyone shed a light on fixing this problem?

My Nexus 6p is now facing the same problem as yours. It charges less than 3 hours before and all of a sudden two days ago, it has taken 10 hours to fully charge. With all cables and charges faults ruled out, my only guess is the fault lies in the phone. I don't think it is the USB port either. I believe it may be something to do with the software I cannot comprehend. But I currently don't have the time to reflash my ROM. This Resurrection remix ROM served well for the past year.
Currently, my amperage averages out to 350 mA. Sad. I wish someone with knowledge about this can reply to this thread. It seems this question has been lingering here for more than two years already. Are we the only ones who face this problem?
My note 20 ultra won't charge above 96% battery level
I did updated it this month to latest version.
No new app installed.
Never a good idea to charge Li's to 100% regularly.
May indicate a battery failure. Check closely for any sign of battery bulging. If present, don't charge and replace immediately as it can cause permanent damage or worse
It does charge normaly untill 96%. It just auto disconects the charging at that value. I recorded the screen to show the problem

What's the battery voltage when it shuts down?
If there's no swelling and it has good capacity I wouldn't worry about it unless it's within the return window.
You could try calibrating the battery.
If it's capacity has dropped a lot especially in a short amount of time it indicates a battery failure... been there, just done that!☠
I had this problem, it randomly stopped charging around 80% or so. I sent it in for repair 3 times -- each time they said "We see nothing wrong with the phone." On the 3rd time I send in a link to a Youtube video and pictures of the phone stopping at odd times. Then they refunded my purchase price. I bought a new Note 20 ultra, hoping the same thing doesn't happen again.
Post back if you find a resolution.
