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

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.
Hermes Charger

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.....
I know there is a bug in which after an overnight charge, the unit is unresponsive unitl you soft reset it. I've read the thread. My TP exhibits this problem as well. However, mine seems to have an additional problem not mentioned in that thread. After charging overnight, my TP IS NOT CHARGED! After an overnight charge, the battery is nearly dead and a soft reset does not fix that. It has happened several times now. After plugging it into the charger before bed, I confirm that the charge light is on and that it shows charging on the status screen, however, THE BATTERY IS NOT CHARGING. Has anyone else experienced this quirk? It doesn't always do this, however, so I'm very confused about what is happening.
Dumb question - but are you using the factory charger? I had a problem when I purchased my Touch Pro in the fact that I used another charger which also was USB for another phone, but for some reason had that problem. Using the charger supplied with the phone fixed it.

Yup. Factory charger and cable. Not a dumb question, BTW. That could have very well been the problem although any USB charger should work.
What about if you turn the phone off and charge?
On a related issue, I used TomTom the other day for a 1 hour trip with the phone on a USB lighter socket charger. Started with 48% full battery, when I finished the battery was down to 30%!!! Basically the phone uses more power than the USB can provide when the screen+GPS is on!! I also find plugging the phone into the charger with the screen on & WiFi on will mean the phone charges at a speed of 1% every 8 minutes - taking all day to charge from empty!
To ease the problems I purchased a separate phone+battery cradle off eBay and a spare battery. I swap to the charged battery every morning and put the other one in to charge. The used battery is usually at 25% after a good days use. Before I did this and charged using the USB plug I used to get 6 hours use before needing to re-charge.
Disconnect the cable from the factory charger and plug in in your PC, see if it charges there. If it does, then you can return your charger, if it doesn't then i'd return my TP.
I have had the Touch Pro for eleven days(got in October 31,2008) and I have issues with the phone. First, I love this phone, however, the battery will not hold a charge. I started with a fully charged battery, used sprint navigation to direct me on a 2 hour trip. My phone was dead by the time I got to my destination. The phone was extremely hot, I mean extremely hot during the entire trip. The next day I took the phone into the sprint store and they switched the battery and told me that the phone check out okay. for the next several days, i used the phone sparingly to see if the battery was okay. I made about 7 calls and 12 text messages, my battery was down 3 bars after being fully charged. I tried the navigation within the city limits and the phone again stared to get hot. My sprint picturemail would not work, it takes hours to send a picturemail. I call customer care and talked with technical support, who did not have a clue about the phone, they had me on hold, researchec, told me to do a few things and then had me to perform a hard reset. The picturemail worked for a few messages and then it started to take hours to send a picturemail. i then went into a sprint store for ready now service to see if there was something I was doing that was causing the battery loss, etc. The CSR in the store did not have a clue about the phone. He went through the computer told me a few things to do and that was it. My battery continued to perform poorly, so I again called customer care and was told afte a serious of conversations and procedures that i need to have the phone replace and that my phone could be defective. They told me to go in to a store and have them make the switch. Well, there are no phones in any of the stores in my area. I call customer care again and asked them to look at the notes on my account and send me a replacement phone, because there are none available in the stores. That was a horror story and i currently have an expensive phone that i have to keep on the charger. i actually purchased a universal charger from sprint that can be used in your car and/or in a wall socket to make certain I don't lose my charge. I think the phone is over priced for how it is operating for me. Sprint should provide an additional battery for the touch pro like they do for the Instinct. The should also include the universal charger in the box. The phone cost to much to not operate better. The sprint picture mail sucks, The sprint TV sucks, but the phone is really nice, if sprint can correct the issues mentioned.
I don't charge it at night cuz i don't like to "overcharge", so i usually charge it when i get home b4 I sleep. I have been considering getting an additional battery with a dedicated battery charger from HTC though. ever gave that a thought?
I seem to be having this same issue with my Fuze that I just got yesterday. After a full night on charger it's at 82%. I'm going to try it over usb on pc to see if it gets any higher otherwise I'll be taking it back to the store today.
The HTC touch pro (with factory ROM) is protected from overloading. Which means that overnight it will load for about 3 hours from an empty battery and then it is full (white light will go from sliding to full circle). After that the charging stops. Which means that if you sleep for 8 hours, the remaining 5 hours your phone will be using the battery.
Now the question remains, what is drianing your battery in 5 hours? The initial suspects are GPS (any GPS software should be cleared from memory, press the most right corner icon to see what's running), the wifi or the HSPA / 3G connection. Use comm manager to put those off.
Of course, the second option is that the charging is not happening because of a defect, in that case return it to the shop.
Pretty sure this is a common problem, I don't think returning the phone will solve a thing.
My phone does the same. Though if you charge it with the phone turned off, it charges fine. I purchased a separate charger and spare battery and just swap them over when I need to (1.5 days with moderate usage).
Pretty sure this is all down to the phone using more power than it should be, hopefully future rom updates will fix this. Even when using Tomtom in the car with the phone charging on a USB cigarette charge cable can't charge it - it actually has less charge at the end of a long journey.
Oh and I can also mention that I have the original HTC battery and two spare batteries (which look like copies with, the HTC sticker is there but not quite the same). The spare batteries act just the same as the original HTC battery.
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.
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.

Hey guys, As title says, So the story on this thing lol Bought it new I believe 1.5-2 years ago, battery got bad, so this spring in february I replaced the battery my self, I had ordered 2, Both certainly a genuine battery, I had a S7 so I wanted a spare for mine when IT came time. After battery replacement phone was great again, good as new! then as of 3 days ago random shut offs. battery reads 80% shut off, Then I noticed If I left it off for a few hours or all night and turn it on in the am 0%! Tried charging and It's not taking a charge really, It went to 9% and stayed there for ever and was getting hot so I didn't want to risk it. ok so bad battery, this morning I swapped in my OTHER spare new battery, and Let it run up to 100% before turning on for first time, All seemed good! then all the sudden after 6 hours (before it was like every 10 minutes it'd shut off.) It started doing it again, Same thing battery is dead it figures, But it can't be.
Thinking perhaps the board it's self or something just ain't right? :\ Any thing to check or tips/tricks? I tried googling and came up empty handed.

It's likely the batteries you have are not genuine. Fake copies don't have a control chip which interfaces with the device. Your phone is shutting down to protect itself from overheating and other problems caused by copies.
There are some great copies out there but trust me they're still copies.

Yeah that's for sure on the copies, I had looked at how to compare what I had VS the fake ones and they seemed to be genuine? The batteries came from 2 seperate sources as well so hard to say, if the first one I put in was a copy then it did last a while but surprised then that my 2nd one never made it more than a few hours and the same issue. But you just never know. Everybody claims your buying a genuine battery but I'd assume the listing prices are tell tale of a fake/copy lol
Monitoring the battery and either the voltage sensor is bad or the battery, it'll chwrge and say it's full but yet voltage goes to 3.4v, then if I plug it in again it'll go up to 4.2v, once I unplug it, it drops of course, I was using a battery burn program and Itll drop from r. 2 to 3.4 right away, I got it to run for 15 mins one time then it dropped off, otherwise another time from 4.2v it dropped to 3.0 then shut off after starting th test in like 20 seconds, reports battery immediately as 17% after re booting.
This battery sat for a while so will try a 3rd fresh battery and hopefully genuine, though I suspect my past 2 were genuine.
Wanted to update this for anybody who may find this thread off google. I got the same replacement battery again Which was the fix, Asked the seller and they said they'd shoot me a new battery, Again whether genuine or not... Well they claim genuine. I let the phone charge to full and Performed the battery draw test by running the 2 apps to bog the phone down and make everything run to 100%. ran like that 0 issues for about 2 hours, Voltage was very stable the whole way through, before It would maybe hold for a few mins then shoot right down from 4.0 to ~3.2V. Even now after a hour It was still well above 3.7V. My old s7 battery was exactly that, sat unused on my shelf for ~2 years because it was mis-placed and even installed it was no good either.
