Hi
I have upgraded my Dopod 838pro from WM5 to WM6 with the official ROM from HTC.
I connect my 838pro frequently using USB cable to my desktop to surf the net. In order not to ruin my battery, I disable the USB charging feature in WM5 (under the power ->advanced tab).
However, after I upgraded to WM6, this feature is lost. I tried the registry hack for WM5 but it didnt work for me in WM6.
Can someone help to let me know how can I disable USB charging in WM6? Thanks a million.
Why do you care? A brand new battery is around 10-20 bucks in ebay. I have been charging with usb for the last 4 months and didn't observe any significant battery life drop. I wouldn't mind buying a new battery for $15 every 2 years.
I would be changing my tytn in 2 years anyway.
I have been charging my previous battery frequently and it last only 5 hours from 100% to 10% with minimum usage now. That battery is only 1 year old. I have just bought a new battery and hence would like to preserve it abit longer until I have found my next good phone
Plenty of people have reported batteries going down quicker with certain ROMs, especially dependent on the radio version. Is it possible your battery is not the problem? Is the new battery definitely better?
When the light turns green it's stopped charging, so shouldn't overcharge. Li-ion batteries don't have memory problems.

It's not memory problems that these batteries develop. It's more that they have a certain number of charge cycles before their performance degrades. Most Li-ions I believe are rated to about 500 cycles tops before the battery life drops below 80%. So every time you plug it into the computer it would kind of count as a cycle. So a large amount of charge cycles and these batteries will degrade much quicker than normal.
Since 1 year I allways connect and charge nearly every day my little toy via USB. Never had battery drop. Even now with the new Radio and WM6 its works much longer as before.

I second that. It sounds more like a rom problem than a battery problem. After
all, there are people (including me) who keep charging via USB and don't
experience battery problems.
The last 4 months I've only charged my device with the USB connection and have no battery problems.
BTW: There is no way to turn the USB charging off, unless u cut some wires & remove some pins. see prior thread discussion:
http://forum.xda-developers.com/showthread.php?t=273344
I charge my phone like a million times a day it seems. Between car charger, home charger, usb from my pc. It gets plugged into things at least 3 times a day if not a lot more when I'm at home messing with stuff on it while its plugged into the pc. Battery works just as good as it did when I got the phone over a year ago. And working in the cell phone industry for years I still say that this phones battery life is amazing compared to most other phones. Even a year later this battery seems to last longer than any other pda battery especially considering all the things I do with it. ie: gps/irc/streaming audio/video via orb/talking on the phone with the woman. Can usually go 2 days of avg usage doing all that providing hsdpa is disabled. Once I turn on hsdpa I get almost a full day of avg usage.
Edit: All that being said, seems like a big waste of time worrying about disabling charging over usb considering how cheap a new battery is and how little a impact it seems to make anyway considering other peoples testimonials. Just my 2 cents.
Found this in Hermes Wiki:
Disable charging when connected to USB
Registry entry to control USB charging:
[HKLM\\Drivers\BuiltIn\Battery\EnableUSBCharging]
if EnableUSBCharging = 1 --> Phone will be charged when connected to a USB power (laptop, etc.)
if EnableUSBCharging = 0 --> Phone will not be charged
I have not yet tried this myself though.

Li-ion Batteries
I was doing some research about Li-ion batteries and came across this info - How to prolong lithium-based batteries.
Seems like the more you charge them and not totally discharge them the better.

I have a DOPOD 838Pro which I upgraded to WM6.0 as well. The battery issue is well documented and has less to do with cycles or memory effect than it has to do with your settings. Upon upgrading from WM5.0, I noticed that the backlight setting for "on battery" was reset to half way. I normally used it on the leftmost side turning the display readable indoors. There is no point in setting the backlight to the maximum or even to the middle, as the screen provides poor reading outdoors anyway.
In my experience it increased my battery life between 25 to 35% taking an average working day, i.e. average number of hours on the phone.
Cheers
You can get a replacement battery here for only $7.29 shipped. Shipping takes about 2 weeks though but cheap.
Only had my Hermes a few weeks, but I've owned Compaq/HP IPAQ's for the last 6+ years. They always said in the manuals it was best to keep the device connected/charging as often as possible. Out of those devices I have only replaced batteries once for each device over the years, so I think it works well. My Hermes gets connected to my desktop at home and work most of the time, though I admit since its a phone and has better battery life then my Ipaqs I do connect is a bit less often.
That said, as others have written, batteris are cheap and unlike Apple devices, user replaceable. Thank you HTC!

Thanks alot for that. I needed it. My laptop used to charge when i connect my HTC Touch Pro, but then it stopped. I changed the registry you listed and it charges again.
Ok, this is just plain frustrating and I have no clue about what to do.
The lifetime on my phone is dropping ridiculously fast. I replaced the original batery (that used to get ran down pretty quickly, about half a day, without using the phone much) with a spare battery a friend gave me (it's from a different model, but a minor modification it fit perfectly. For a while, it worked somewhat more decently (although should I have used the phone, I'd lose about 1% for every 30-45 seconds of usage). But for a couple of days, it started wearing down a lot quicker as well.
For instance, just charging the phone and then leaving it without actually touching it on the desk will leave it at 88% battery life within about 30 minutes.
I've checked the processes to see if there's anything out of the ordinary, but everything seems fine. I'm thinking maybe the battery may have gotten damaged in the meantime since it wasn't the designated model for this phone, but I'm having serious doubts.
Also, I've ordered a new battery which should ship any day now. Hopefully it will solve the issue, although I'm considering getting a new phone.
Any ideas?
Also, the old Asus that I used to have (WM 6.0, standard keyboard) still has an amazing battery life, at least compared to the HTC (it can do about 3-4 days in standby, and 2 days with normal usage. Also, it's able to run for 12 hours while playing music and occasional web browsing. I can barely squeeze two hours of usage from my HTC)

Maybe you should get a new and proper battery to your device, maybe your fix does not work anymore. Also you can damage the excalibur motherboard if your messing with different volts from batteries design for other phones.
Well, the battery voltage is the same. So is the pin layout (well, that was pretty self implied). Both batteries are manufactured for HTC phones.
I guess I'll find out when my new battery arrives. However, my phone has been acting weirder and weirder. SD card issues, now the battery... And on top of that, I wonder if the two issues are related.
Edit: also, will the charger output make much of a difference? Say I use a 500 mA charger or a 1000 mA one.
Issue solved. Apparently it was from the SDHC patch I had installed a few days before. Removing the patch did not solve the issue (also, the patch disabled my WIFI) so I proceeded to reinstall WM on my phone. Now it runs fine, with regular battery drain.
I think the patch may have not allowed the CPU to enter idle mode. I can't think of any other explanation.
nah its definitely ur battery. i had the same problem, its that ur battert has degraded and it has become unable to withstand its charge. just call ur phone carrier and tell them. the should send u a free battery.

I know some HTC batteries are the same voltage, but why do you think they make different ones especifically for every model eventhough they have the same voltage.
Just to let you know and regarding the output charger; I did a little experiment once, with motorola chargers (V3) since you can charge your dash with them but I tried to charge the exact phone (motorola) with the original HTC output charger.....and it didn't charge at all.
After months of using the motorola charger I started to realize my battery was not working well in my excalibur and in a period of 4 months my battery didn't hold a charge for more than 3 hours. I bought a new one and I strictly used the orginal HTC charger.
My battery is 9 months old now and works like charm (2 days + hours) with the latest ookba 3vo rom.
Hi, I am noticing that my battery life is very short. I have to charge my phone atleast twice a day. Last night I watched a program on my phone which was forty minutes long. After that my battery was already 60 percent about. However.now, in the morning, I woke up and checked one thing on the internet by 3g and now my battery is already 40 percent. Why is this .... I know that battery life on here is not good but mine seems worse.
Is anyone getting the same?
Thanks in advance.
Tell us your settings:
- Do you allow background data?
- Do you always synchronize?
- Do you enable data connection?
- Do you connected to the Wi-Fi all the time?
I swear my battery life is far far better since i put that Generic rom on, maybe the minor updates htc have released help battery life ?
Maybe the update will fix the battery life issue? We'll see when it rolls out on t-mobile handsets.
Other people have reported excellent battery life (mine only arrived today) and it seems to improve over time. How long have you had it?
I had mine 1 week today was originally on the T-Mobile rom and have had terrible battery life up to even yesterday, updated to the Generic Rom yesterday and it honestly seems to last longer now.

I was waiting for someone to report this before I did .. I too was originally on the T-mobile ROM and updated to the Generic ROM. I didn't notice any increase in battery life. In fact I didn't notice any changes apart from the minor T-mobile branding having gone.
Yesterday I did the OTA update and again didn't notice any changes. I did this morning though, in 10 hours the battery only dropped 4%. Of course the phone hadn't been used in that time and I have wi-fi and bluetooth switched off but I am sure this is a lot better than I was getting.
Maybe the OTA update has improved battery life. Let's hope so.
Hello again,
Is the generic Rom the Rom without the T-Mobile stuff?
How would you get that? And would that remove your warrenty / insurance?
How have some T-mobile people get the OTA update whereas some have not?
Have you realy found a difference with it?
THank you

Yes to without T-Mobile stuff.
You can download it in the Android Dev Desire section on here. There are extra steps to take.
It WILL void your warranty.
Anyone that got their phone direct from T-Mob will NOT have it unless they did it manually. And by that i mean manually flash generic rom then update.
I noticed my battery is better but it's only one day. And i never really had a problem with it. I charge once a day anyways.
Thank you for the help.
However I am unsure if I should get the generic ROM.
What are the other advantages?
Because there is not a lot of T-Mobile stuff on there.
If I got mobile insurance with T-Mobile and flashed the ROM would I be able to claim if my phone got damaged or lost?

Advantages. The phone is as it would come straight from the manufacturer. You will always receive updates for the device before Vodafone, O2,T-Mob etc would have them ready.
If the phone was lost then yes. If damaged...probably not but if it develops a fault you can always drop it in a drink and claim on he insurance...bit dodgy like!
My battery life story
So, I downloaded the brut Google nav mod the other day and haven't had a chance to use it until today. Took a journey which took about one hour, and made sure that my battery was fully charged before I went. I still hooked up the phone to the car charger though, to save power. One thing I noticed about charging the desire, however, is that if it identifies the battery as being already full when you connect a charger, the indicator light stays green, so doesn't top up even when you have been using it for a while. I noticed this about 20 minutes into my journey by which time the battery must have gone down quite a bit. Removing then replacing the charger sorted the problem and the Orange light indicated that it was charging again. By the time I got to my destination the battery was at about 50%.
On the return journey, I hooked up the phone again, turned on Google nav and set off. About 30 minutes into the journey I stopped off at a petrol station to grab some snacks, checked the battery and read 17%! Even though it was supposed to be charging the whole time!! I then got a message saying that the power from the car wasn't enough to charge the phone and I should attach AC power ASAP, which I obviously couldn't as I was in the car. I ignored it, got home safely enough, disconnected the charger and then watched the phone die .
Ok, so I was using gps and 3G which clearly uses up power and I guess Google nav is fairly processor hungry, but I would assume that having it connected to the car charger would be enough. Coming from a tocco ultra, I'm used to rubbish batteries, but at least that would charge up in a car.
Don't get me wrong, I still love the phone, but I just need to know if this is gonna be a regular issue, or something that can be sorted out with a Rom update.
Just for info, I've had my desire for nearly a week now on TMO using the old Rom. And, the car was Passat estate which is in very good nick, so I doubt that was the problem.

I would look if the charger really charges the phone or if it drains it also when not using GPS/Nav etc.
Reason I'm saying this is that I once bought a charger that actually drained the battery instead of charging it, while it worked fine on my older Nokia phone. I'm assuming the phone deactivates some power saving features because it thinks it's hooked up to a charger, but at the same time the charger is too weak to actually charge it.
I have not used branded rom before on this phone but the htc rom battery life is fine. Mine has been going for three days with usage fine

nice, 3 days. how many times u charged the phone since u got it?

intresting my battery last a day
I just started charging 2nd time my battery and it lasted hmm since about 2pm till 15% at about 00.00 which is pretty much 10hours of heavy use. i did leave it on sleep for about 2 hours though and i left it at 25% and after that it had 25-24 % lol so if you turn all the updates off it will last quite a lot i guess
I rang up T-Mobile today (tech support) to ask about the lack of update considering the rom was behind the non carrier phones at the start and then an update too. They said they do work on them when they see a notable difference worth updating.
Anyway, I also said I was incredibly dissatisfied with the battery and how long it lasted and wondered if it could be to do with the ROM being well behind the stock HTC one. The tech support guy was excellent and very helpful. He said that with the type of battery in the Desire, you need to make sure you have it on a MAINS charger from quite low for a good couple of 14 hour sessions with the phone off. This builds up the charge for the battery and you should see a marked improvement. He said that most people don't bother to do that and as a result get poor performance.
He did say him and 4 members of his team have the same phone and while some of his team had battery issues he didn't. The main reason being that he had spent a few days not taking it to work and running it down in the evening then giving it three 14 hour chargers. He said that made a huge difference.
He also said if I was dissatified to a point of big frustration they would replace the phone or refund. Can't ask fairer than that

yeah, I turned mine off a few hours a go and will leave it off until tomorrow.
So the battery life absolutely sucks on my One. If I start using it at 8am its dead by 5 pm. And that's just normal usage like surfing the web over WiFi, playing games (candy crush, dots, angry birds space,) maybe watching a few short videos over WiFi and the occasional text message. I have a battery saver app and I can see that it helps but I guess there's only so much it can do,Z so I want to get one of those cases that has an external battery built in. I have a few questions.
1. Does anyone here use one of these? Please give your input.
2. What's the best one? I've done a little research and found that the i-Blason and Mophie ones seem to be most popular. They're both a bit pricey.
3. How do they work? Does the phone just start directly using the external power after you switch it on, or does it just charge the internal battery?
4. Can these things have any kind of adverse effects on the internal battery from odd charging voltage or anything like that?
5. Do they actually extend your battery time as advertised? I'd be happy with getting two full days out of a single charge and some of these things are advertised as extending it by more that 1.5x. It seems like if the external battery is just charging the internal battery it would be a bit less efficient than if it were directly powering the phone. Does that make sense? It just seems like there couldn't possibly be a direct conversion of 2300 mAh from one battery to completely charge another 2300 mAh battery.
I hope that wasn't too confusing. Personally, I can't wait until lithium-sulfur batteries are in all our electronic devices (potentially 4x energy density.) Google it. Sounds promising.

1. I don't use these so I can't comment on this.
2. The iBlason and Mophie are the only ones available that I have ever seen. The Mophie being the higher quality (materials not necessarily battery life) of the two but also twice the price.
3. The phone will use the battery cases charge first then once that is drained use the phones internal battery. However if your phone battery isn't fully charged and you plug a charged case into it, it will charge the phone.
4. It's a good question and I'm not 100% sure. If you use it properly it shouldn't cause any major issues. Using it "properly" meaning your phone has full charge when it is paired with case so that the case isn't charging the phone. That being said, the damage is no different than someone constantly charging and discharging their phone in short bursts rather than using it until it's dead (or as close to possible) and then fully charging. The big thing to be aware of is that the damage caused is simply a reduced battery capacity and usually isn't big enough to notice during the life span of the phone (1 to 2 years).
5. Yes they do. Some of the claims may be a little higher than life experience, but nothing drastic. It litterally adds a second battery to your phone, so it IS going to extend the battery life quite noticeably.
One thing though, I have had my HTC One for a month or so now and have kept it stock, occassionally trying custom roms, but always going back. I have consistently been able to get over a full days use with WiFi always on, GPS always off, brightness always on auto, and I have exchange synced and set to push notifications. I am constantly checking email and texting for work as well as browsing the internet and Google Currents. I also have the power saver turned on. A full day use for me being from 8am to around 12am.
I think either something is wrong with your phone, you are playing too many games, or some setting or service is draining your battery. I would post your battery usage here for some to inspect. And it might be a good idea to uninstall the batter saver app, they usually don't make any huge dent on battery life that can't be done without the app, since most rely on a polling service that runs in the background and eat up battery life themselves. Just make sure your sync settings are reasonable (not every 5 minutes), turn off GPS and only turn it on when needed, don't turn on WiFi unless you need it, turn off 4G unless you need it (switch to CDMA only in mobile settings), enable eco mode (power saver that throttles CPU based on usage), and make sure brightness is set to auto or a medium to dim setting.

Mostly right. I'll toss out though that cases have different current outputs-- the mophie cases will output at a high enough rate to cause a phone to register as being on AC. the i-Blason case charges at about a third of that rate, meaning that it'll trickle charge your phone/reduce power consumption rate, but it won't outright charge unless you're not using it.

I hope that wasn't too confusing. Personally, I can't wait until lithium-sulfur batteries are in all our electronic devices (potentially 4x energy density.) Google it. Sounds promising.

1. I've used one for about 2 days. I returned it. It works well and the Mophie definitely feels of high quality and feels great in hand. However it makes the sleek device very big and bulky.
2. I would recommend the Mophie purchased at your local corporate carrier store, reason being is that usually your carrier will offer a 1 yr warranty on a premium case like this. However if you break or it shows ridiculous wear and tear they wont. I cannot comment on I-Blason's warranty. Although I think the Mophie is perhaps more expensive. Some carrier offer discounts based on employer's of the account owner. So that might help get the case cheaper.
3. See comment below
4. Usually since they're molded directly to fit your device, most manufacturer's will accommodate the OEM's requirements. But the Mophie charges as fast as it would if you had plugged it into an AC charger.
5. This question is a bit more confusing for me to answer. All I can say is that if they advertise a 100% charge then that means they're matching the mAh capacity of the device. (Ex. phone model has a 2000mAh battery internal and the case advertises 100%, then that means the external battery is also rated at 2000mAh.) So in reality if you're expecting a complete 100% charge while your device is still on, then no, you may get from 1% up to 70-90% depending on how much you're using it while its charging.

This is not entirely true. Because the Mophie has an on/off switch. So if the case is set to off, it'll use the internal battery first, then you need to switch the battery case to on to begin charging the internal battery. It is entirely possible to use the phone till it completely shuts down when it run out of juice and the Mophie have a full charge.
It uses the same charger as the phone itself so the case never has to come off, however even if the switch is set to off it'll charge both items at the same time.

I was not aware they had an on off switch, that would change the way the phone handles the device and give you a bit of flexability in how you use it, which is good.

I wonder if it would use the case battery first if you turned it on when both are 100% charged. Everywhere I've read, people seem to use them to charge the phone after the battery gets low. It would be great if the phone would just draw power from the case until it dies and flip over to the phone battery. I feel like that would keep the phone battery more healthy by avoiding inconsistent charging. If you're constantly killing the phone battery and using the case to recharge to less than 100%, then killing it again... it just seems like that would be bad for the battery.
Thanks everyone for the input! Keep it coming!

Good question. My thoughts would be that the phone would only draw enough to keep topped off. So I guess if the switch is left to the on position the whole time you would get the desired effect of draining the external pack first. But I would guess that doing that would reduce the efficiency of the case somehow.
In the end whether your constantly killing and charging your battery no matter to 90% or 100% with the case or A.C. charger, doing it more often will kill your battery either way. Given lithium ion batteries are way more forgiving than the old cadmium based ones that built up a memory of sorts.

To keep the battery healthy in a phone, make sure you charge to 100% each time. You don't need to fully drain battery, it's actually healthier to go from 50% to 100% than 1% to 100%.

So if my phone only gets down to about 40% each night before I plug it in to charge all night I'm ok? In the back of my head I'm always wondering if I need to drain it all the way sometime.

You are fine, it's better to not drain the battery all the time. It lasts longer if there's charge left. You just have to make sure your fully charging to 100% and not charging only to 70% or something like that. This is how lithium batteries work in all devices, laptops etc...

So I've been thinking about this a lot over the past few days and I have something else i want to throw out there...
If you have your phone plugged in to a charger while at full charge, you can use it all you want and it will never go below %100. Does this mean that it's completely drawing power from the charger, or is it still drawing power from the battery, which is just constantly being topped off? Because I know I can completely remove the battery from my laptop and as long as it's plugged in to the charger, it will continue to function just fine.
If the phone is drawing 100% power from the charger, doesn't that mean that it would do the same for one of these battery extender cases?
Like I said before, I think that would be a lot more efficient that just using the case to recharge your phone's battery after it gets low. This way you sort of cut out the middle man.
BTW... I found that there was a weather app that I think was constantly trying to access my location even though I have location services turned off. I now get a good 10 hours of battery life with moderate usage. Still want a battery extender case. 2 full days would be awesome.
HTC battery life DOES suck compared what it can do because you are not going to buy a phone like this if you wont chat/text/call/email/play games alot. Mine lasts 10-15hours (usualy 2.5-3hours screen time and NEVER more than 3) and thats annoyng because its ok if im just ordinary home-work-home rezime but if i need to go out of the city for lets day 2-3 days - im screwed and allways must think about charging.
I have overlooked everything nothing wrong with the phone - the battery is just too small.
i keep wifi ,gps and bt off if i dont need them but my phone ofcourse syncs everything (thats the point of a smartphone - to be connected!) and i play often also.

Nope its being topped off, phones are all about maximizing space in the phone, it would require more wiring for the motherboard to be able to draw power directly from the micro usb port as well as the battery. For example, my Samsung phones can be plugged in but if I take the battery out the phone turns off.

I got this one - all day w/o charging w very heavy usage. Traveling w/o signal - 2-3 days no charge. Makes the phone bigger and you can't see the gorgeousness of the phone, but it protects it all around and it lets those 4 cores and crazy display to do its job w/o dying on you fast.
This guy sells them for $20. Have seen them in other sites for $70-130. Same exact model.

1. I have the i-Blason black.
As a Case
Pros: Great volume controls, Black matches the black HTC One and the black earbud plug, kickstand, central USB plug.
Cons: Thick, Gets Warn when plugged in
3. There's a button that turns charging from the case on or off. Phone will be like it's externally charging.
4. The i-Blason is a lower current charging, so there's a warning that pops up. I think it's not harmful.
5. Extends, yes. But >1 day, no. Well, if you're not using the phone, yes, > 1day. What I do is I let it charge the phone when I'm not near a usb plug and it gets < 80%, then i let it trickle back to 100% in about an hour. It automatically stops charging the phone at 100%.
Learn how to manage your phone guys. Track down the offenders instead of buying these battery packs and other nonsense.

Hello everybody.
I just want to share with you guys what I found out.
I've been using custom ROMs and custom kernels for LG V30, and I faced a lot of issues. The most common issue is overheating, especially on charging or using mobile data.
I use Anker's adapter that supports Quick Charge 3.0, and an Anker USB-C to USB-3.0 cable. I use Ampere app to see how the battery is charge.
On custom ROMs, the ampere number (mA) changes every few seconds, jumps up and down with big gap, and the phone gets very hot.
On stock ROM (US99820H) in my case, mA number is very stable. It increases or decreases slowly and doesn't jump up and down. On plugging in, min and max mA are equal. The phone is just a little bit hotter than before plugging in.
So I just wanted to share my own experience with you guys. If you want you phone to last long, use Stock ROMs, disable bloatwares and useless system apps.
I'm going to purchase the battery and change it myself for better battery life. I wanted to change to another phone but for now, this is the best phone for music.
Please discuss if you disagree with me or have a solution for custom ROMs.

I also felt the same...Though the charging speed on custom roms is higher...in terms of stability of current, Stock Rom is the best.

In terms of stability, I have different results, when I charge using a custom rom the phone tends to stay cool, but when I used the stock rom the phone got a lot hotter then before charging.
Custom ROMs may not be utilizing QC properly. QC 2.0 has few discrete voltage/current steps, while QC 3.0 has many (200mA increments iirc) designed to strike a balance between charging speed and heat. Maybe it's getting stuck in QC 2.0 mode and the temperature feedback isn't working properly?
You could just use a non-fast-charging wireless charger, if you're only charging up at night. 5v/~1A is pretty much harmless, it's just on the slow side of things.
fyi, battery capacity (as tracked by the charging controller driver, I guess) is stored at sys/class/power_supply/bms/charge_full; it defaults to design capacity until a full charge cycle has been completed* and then I suppose is revised each time the driver tracks less energy has been stored after a complete charge. Cycle count, cell resistance and a couple other things are also stored here. I think all values are persistent until the battery is physically disconnected.
Might be worth doing a full discharge+charge (to 100%, then let it sit for a few hours to saturate) to see if your battery is worn enough to warrant pulling the phone apart. Accubattery does seem to be more or less accurate, so you charge while it's on you can get a real-time idea of how much has gone in.
* a full charge might be from 1% to 100%. It might be from 5% to 100%. Who knows! I've charged from 2% to 100% a couple times and not had cycle_count increase.
Also, if you do go shopping, beware of undersized batteries. I bought an "OE spec" battery a while ago that was obviously thinner and lighter than the original; it weighed some 12.5% less and only took a 3000mah charge, more or less lining up with the reduced weight. The seller was "tele*cell", and I very much doubt they're the only ones pulling this crap. Record the contents of power_supply/bms if they're important to you, too, as they zero out upon battery disconnect.
edit: hmm, thinking about it...bms = Battery Management System? (not this one specifically, of course)

It is possible that you bought a smaller battery - but you should know that the capacity of Li** batteries increases within the first couple of cycles. Also usually the nominal capacity might be different from the real (typical) capacity. So you would need to meassure a.new original battery against your replacement battery (not take the value LG tells us for.granted)

Li-po capacity hasn't really gone anywhere in a while, and I wouldn't expect cheap eBay batteries to be using the newest and best chemistry. It was definitely undersize/weight; I attached some pictures.
Because I wanted to be absolutely sure before I called the seller on it, I purposefully ran it four full cycles, then built up another two during normal use. The best capacity that the BMS ever rated it for was 2980mah, while Accubattery put in something like...3060mah once with subsequent charges in the 2900-3000 range.
While I get what you're saying, I find it unlikely that the BMS would set to the expected design capacity if they were using undersize batteries from the factory.
The reason being that at a guess, the battery "fuel gauge" is probably based on capacity_full, which = capacity_full_design until set. With a new phone that isn't charged to 100% (thus setting capacity_full), if using the phone down to 1% you'd risk either a) the phone suddenly shutting down at ~10% or b) overdischarge damage if the battery is actually less than the phone's design capacity.
Kind of a corner case though, I'll admit, since this would only be on the first run.
Last, I submit my own OEM battery for consideration: prior to taking it out, it had accumulated 537 cycles and had a recorded capacity of 2485mah. That's about what I'd expect from a 3300mah battery that was almost certainly used "normally" e.g. discharged daily, charged nightly and left on the tap at full charge for hours on end.
Like you said, though, the only way to know for sure would be testing a new OEM battery, and we've been fresh out of those for a year and a half now. Maybe someone could nab one from one of their newer models and test for science? I already have too many spare lipo cells laying around.

Do you have sleep problem after changing the battery? After changing the battery, my phone doesn't go to sleep when the screen is off, so the battery just keeps draining. I'm using stock ROM. I don't know if this is a software of hardware issue.

The only thing notable that happened was the battery stats getting wiped. Otherwise the phone behaved normally.
Try getting BetterBatteryStats, second post has the newest apk attached (2.3 iirc).
Start it up to get it established, Set Custom Ref. from the menu, shut the screen off for...ehh...20min.
Turn it back on, select Custom in the left drop-down menu and Current in the right drop-down menu.
Check Kernel Wakelocks and Partial Wakelocks using the top drop-down menu to see if anything sticks out.

What is the full capacity when you put those 2 battery in?
I just bought a battery. This new one has 6 symbols each line (like the one you bought) and 2 lines of manufactured date. The old (original) one has 5 symbols each line and also 2 lines of manufatured date.
When I check "charge_full" after full charging, it shows 3312000 for the original battery and 3230000 for the new one, while the "charge_full_design" being 3312000 for both battery.

All three batteries I've had showed the same 3312000 charge_full_design. But I'm not sure if this is relevant to us, aside from as a reference to compare to.
Out of curiosity and so I don't purposely give outright bad information, I went and looked at the kernel (up on github courtesy of lunar-kernels).
3300mah design capacity is set when the kernel is built (BLT34 battery profile, which is grabbed by the power manager).
I'm not sure where the number "3312000" specifically is coming from. I can't read the source for the BMS well enough to tell why it's coming up with that number, aside from it's a calculated result based on more than just the design capacity.
Based on the above and other behavior, I don't think any permanent information is stored with or retrieved from the battery itself; design parameters are set in the BLT34 profile and then the BMS amends certain things as it takes measurements. It assumes that whatever attached battery is actually 3300/3312mah until proven otherwise (calibrated with sufficient cycling).
Said measurements are stored ~somewhere~ outside of the ROM, recovery and download mode - mine persisted through the LAFsploit process and TWRP on both partitions - and cleared when power is lost. Maybe they're stored in RAM somewhere? Maybe the BMS notices the discontinuity in power and assumes a battery change, resetting everything? I'll try making sense of the kernel source to see...
The labeling difference is curious, and something I hadn't really given thought to. The newer ones have NOM and NYCE marks, which are Mexican safety approval things. It's interesting that the originals don't have them; maybe because LG doesn't make phones for the Mexican market and thus saw no need? I doubt these third-party manufacturers have gone out of their way to actually obtain said approval...probably just stuck them there to satisfy customs.
I bought a battery from another seller and installed it this weekend; it uses the 12-symbol style as well, has date+date code like the original (dated a rather shiny 2019.09.08!), and weighs the expected 48g/has an OE-style "stepped" back making it thicker.
Seems to charge fully and otherwise work as expected. charge_full still = charge_full_design, I'm not sure if this is because the BMS has determined that it's an OEM-capacity battery, or it hasn't cycled sufficiently to update. Gonna keep an eye on it. Pictures attached.
Edit: battery listing on ebay. Note if anyone else buys it: the suction cup that came with mine was 100% useless. Plan accordingly.
-
A further note on the smaller battery I bought: it did perform admirably. It had no issues when using the phone as a power supply (~2.5A sustained output), right down to where I stopped it at 5%, which is rather abusive for cells in this form-factor. It was just...well...smaller. It certainly wasn't a bad battery at all, it was just misrepresented. Lighter/slightly-smaller batteries would make great travel batteries, if the V30 were swap-friendly...

I hope you bought a good one.
The battery I bought lasts long, but also takes long to charge (about 2 hours). The phone shows fast-charging but when I check battery log in Hidden menu, it shows only Quick charge 2.0.
I found a way to reset the battery information, hopefully sellers don't use this to reset the cycle count.
There's a thread on xda that shows a method to reset battery information on HTC phones. That is holding down 2 volume buttons + power button (volume down + power for LG V30) in 2 minutes while the phone is being charged, let the phone restart as many times it takes in 2 minutes. And then charge the phone to full.
I did that and when I check in Hidden menu, the battery information was resetted to 3312000 full capacity and 0 cycle count.

QC 3.0 wouldn't outright increase the speed any; it exists to help reduce heat and provide more consistent charging.
If it makes you feel any better, mine is also getting stuck on QC 2.0. Judging by the way the Parallel Charging status flickers on and off as I move the cable and put pressure on the connector, I could probably stand to get a new charging port...
This is why wireless charging is a good idea. But now that I think about it, replacement boards are cheap on ebay ($5), so replacing it each time the battery is changed might be a good bit of cheap maintenance to do :good:
Have you tried a different cable and/or charger to see if your charging improves? Maybe you need a new port, too.

I find this slightly alarming, actually...
The normal button combination to hard-reset the phone is power+vol down. This might just be what's happening, and by making the phone do it repeatedly, the firmware might be interpreting it as a bootloop condition caused by something in memory and completely disconnecting power in an attempt to mitigate it (clearing the battery stats in the process). Probably harmless though.
Dunno that a seller would bother trying it, though. What do they get out of it, other than a seemingly-new battery with less capacity than it should have? It would just recalibrate when charged and show the real capacity in the hidden menu, and the game would be up :v

All V30 always show QuickCharge 2.0 in Nougat as well as Oreo. Not sure about Pie.
Speculation was it was a script error, that it was really 3.0 -- but falsely shows 2.0.
Can't remember if it was ever proven one way or the other.
I do remember people say it now charges slower on Pie. Again speculative because LG knows batteries are older?
I'm still on rooted Oreo, so I don't care.

I don't notice my phone charging any different. Even when using wired.

I read "the display may not be correct, so you should totally use this as an excuse to get a newer charger-doctor that supports QC".
...and you're completely right, I'm gonna go do that :v

Or to mitigate further aging by reducing internal heat. I also remember seeing somewhere that it was limited to 12w or 13w, now that you mention it, though that might have been for 15w wireless which has a reputation for slow-cooking the battery (in any phone, not just the V30).
