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.....
This is a poll. Again, its your normal day use.
My finding so far: my battery will deplete faster if its charged with turbo charger. I have two MXPE's : one for me and one for my wife. I charged hers to 100% using Turbo and mine with normal charger. Same settings for Moto display, same brightness level and pretty much similar usages. In fact, I use my phone more than her because I am somewhat more active on whatsapp. Her phone deleted faster than mine.
Have you guys noticed any difference in this respect? I am thinking I am going to use normal charger for night and use turbo charger only in a pinch.
I've read this assertion elsewhere too - that any quick charged phone depletes battery faster. Actually I charged my battery with my old slow charger last night to see if I'd lose less today. Subjectively (because my usage isn't really consistent), it seems like maybe the phone is discharging more slowly...
Could be a possibility but i have my lg g3 that i used for a year.. Co pairing my faily usage i get about the same hours of ost.
I think hers may be going down faster maybe because of the background apps or the ost shes using? U cant say ur using the same apps unless u tried them both for ur self..
I know this is the case. I have a Tablet and Phone when I charge them with slightly higher power chargers they deplete at a much faster rate. And when I charge with the slower charger they hold a charge much longer.
(Although bare in mind I'm talking about non Quick Charging devices so maybe that plays a huge part lol but I dont use Quick Chargers on them just slightly faster chargers when I have no choice.)
Sent from S3 via Tapatalk App.
For those of you that have noticed faster battery loss after using the quick charge have you tried the non quick charger for a night charge than at a random time used the car quick charge charger? Does the time differ at all than?
I think this needs more testing. I need to do the test on my phone alone on 2 consecutive working days.
I don't understand what the logic behind this theory would be. Just because one reviewer mentioned it all of a sudden its a thing? Not trying to argue just don't understand the logic. The battery/phone don't heat while turbo charging so why would battery deplete faster?

A lot of people report the device gets hot when turbo charging. By the nature of the forcing of charge and the small footprint, how could it not get somewhat hot? I do not use fast charging on my Pure due to this.

Charging fast is bad for the battery, so it only makes sense for her not to last as long.
My wife wears down faster when I quick charge her. I only do it when I need her for short bursts.

As I understand turbo change. The phone only utilizes turbo charge for the 0-85 or so, then the phone uses standard charging to top the battery off. I have also not noticed any heat while charging using the OEM charger provided out of the box. Believe what you will. I just don't care how you charge your battery.
Sent from my XT1575 using Tapatalk
Why would the phone discharge faster after a quick charge? Isn't one hundred percent one hundred percent? I'm not flaming, I'm actually curious if there's a difference.
Idk who came up with this, your battery does not drain faster when its charged faster, its not logical.. All turbo charge or any type of quick charge does is supplies more a more faster charging rate based on the volts and amps it puts out. This should not effect your batteries life in anyway.
I can understand the thinking behind this but there is absolutely no way you can test this correctly because you aren't doing the EXACT same usage every day. Something will always differ.
Was this ever an issue with previous Moto X's?
After about a week's use I feel like the battery has a break in period. I was getting horrible battery at first. The past few days have been par (4ish hours SOT). I've only used the OEM Turbo chargers once but I have several other Turbo chargers (mainly from Galaxy's, Turbo's, etc). Almost every charger in my house could be considered a "Turbo charger" but I only receive the notification that the device recognizes a turbo charge on the OEM charger.
That said, I have worse battery life if I charge all night. It's as if the battery fully charges, then depletes, but still registers as 100%. So shortly taking it off the charger, the battery will quickly drop to low 90's and soon into the 80's. If I charge to 100% and unplug soon after my battery life is as expected.

You are making an interesting point here. Anyone else can confirm?
I'm going to do a test myself. Before that I want to add that I've noticed when charging with turbocharger(I've used only the OEM's) the charged capacity tends to go a little over the 3000mha, it becomes something like ~3300mha and after plugging out it still stays like that until 90% where it stats under 3000mha charged.
I charge every night with slow charge. I am at 95% after 1 hour and 45 minutes unplugged. Checked some news a few texts and 2 phone calls. Seems normal to me.

Battery drain is pretty evident. I am on MM Indian ROM and below are the findings.
1. Used turbo charger to top it up at 100%. Dis-connected the charger. WIFI is enabled and network is 2G (data off). All background app sync is disabled, and the only major applications running in background are firefox and whatsapp.
With medium brightness and browsing, the battery will drop to 97-98% within 5-8 minutes.
2. 100% turbo-charged at night. WIFI enabled/2G network (Data off). Woke up in the morning after 6 hours and battery is good at 98%
WIFI off and network moved to 4G/data and after browsing for 10 minutes, the battery falls to 85%
3. Instead of turbo charger, used Xaiomi MI pad charger (non-turbo) and my experience with #1 and #2 are pretty much the same.
So, I own this phone for a few weeks now and I got pretty frustrated about the battery life on this phone as I was getting 3 hrs of SOT a best.
Then I decided not to stress the battery so much by charging it with the included turbopower 25 charger all the time, and use my old (5V 2.1A) charger overnight instead. Then I was surprised to see my SOT going up to about 4.5-5hrs.
I did some research about fast charging techonlogy and found out that when you fast charge you typically don't get as much charge into a battery as with a slow charge.
I still use the turbo charger when I am short on time, but using my regular one definetely does add more juice to the battery, thus, helping it last throughout the day.

Please do report
It doesn't really matter, at least not that significantly... something else is the cause.
Using a turbo charger could change the longevity of the battery, over time, due to heat buildup and breakdown of the internal components due to more stress, but it wouldn't just "get better" switching to standard charger... I charge my phone half the week on a standard charger when at home, and when traveling I use a quick charger. If I am on either at home or on the road for a few weeks at a time and my battery life doesn't change. Well, not because of the charger, but at home I am within 30' of a very high quality WiFi router all the time and essentially never on mobile data, on the road it's the complete opposite.
If you did your researching into Qualcomm's Quick Charge 2.0 (and higher) standards you would see that the issue of batteries not getting a full charge from the original QuickCharge/Fast Charge standard has been remedied with high voltage charging automatically downgraded to "standard" voltage charging during about the last 10% of the charge cycle to allow the battery to cool and take a full charge.
Not doubting your getting better SOT, just your analysis of the reason why are...

Maybe you're right, I'm still monitoring my battery life on both chargers, and with the same usage, my battery does last longer when charging with the regular 5V one. I'm mostly on 3G network data and rarely use wifi, as I'm mostly only sleeping or eating at home. Maybe there are other factors making this difference, though i'm pretty sure the charger is the only difference for me. Will report if I notice anything else.
I don't see any big difference, I'm also using standard charger over night and quick when I'm in the hurry. Despite charging methods my sot time is very inconsistant from 2,5h to 4h at best.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the OnePlus 6T can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
dash charge (now called fast charge) is crazy fast!!
Still, I would only recommend using that feature if there is a real benefit - i.e. time is of the essence. The battery will age quicker being dash charged all the time.
saw 60 percent at 35 minutes and 38 seconds, which is more or less in line with what OnePlus claims
Incredibly fast compared to my old Honor 8. One example I have is the first charge I did 5 days ago when I had bought it at a pop-up event here in Sweden. I had used it for about 1-2 hours with the screen on when I was setting it up and trying out the phone. Then when I plugged it in, it went from 36% to 75% in just 24 minutes. That's insanely fast
I've also noticed that just like OnePlus claims, the phone basically charges at the same speed with the screen on as if I would have had the screen off.

Can you provide any factual basis for this statement? Research or articles from established professionals in the field of battery charging?
Everything I've read from reliable sources state that the biggest impact on battery longevity is temperature. Repeated heating (or extreme cooling for that matter) will accelerate the "aging" process, as you put it. OnePlus has actually solved this problem by offloading the energy conversion that causes heat to the power brick, leaving the phone cool during charging (pretty ingenious). I've also read that not always charging the battery fully to 100% can prolong longevity, which is why you get charging strategies on laptops that will stop charging at 80% or 60% if you leave your laptop plugged in 24/7.
Point being, the ONLY way to slowly charge this device would be to use a third party charger and/or cable.
The reason I ask this, is that the manufacturer, OnePlus, clearly states in their documentation that comes with the phone or dash chargers to ONLY use the charger and cable that came with the phone.
Please charge the OnePlus Dash device only with the official Dash Power Adapter and Dash Type-C Cable. Using unauthorized adapter can be dangerous and may void your warranty.

I'm not completely opposed to the idea that this could just be a marketing ploy to get you to buy their own adapter and accessories, but again just want to know if there's any substantial proof that fast charging, by itself, degrades the battery faster, of if it's just a case of incorrect tribal knowledge.
Thanks.
You are correct that the rate of charge and discharge alone are not the only deciding factors on lipo life and certainly not the most decisive ones.
Excessive heat, especially on high charge levels, is the biggest factor for increased aging.
As you mentioned extreme charging levels (completely empty or full) will also contribute to faster aging, albeit the impact is not that extreme for these low current-draw Lipos used in our phones (as opposed to high-drain Lipos for instance).
Discharge and Charge at high rates will also contribute to the speed of aging, but not as much as heat.
When a lipo spends most of its time one medium charging levels at moderate temperatures and is only charged and discharged with low rates on it will have the longest service life.
This is common for all Lipos, just how much a low or high rate is for that particular battery differs (low drain, high capacity VS high drain, low capacity cell)
With Lipos everything is a compromise. Max and min voltages, max temperatures, max draw are values the manufacturer has chosen as the best compromise to reach the intended MTBF. All these numbers are not physical absolute barriers.

First of all, how many device support Super VOOC? How many device you can buy outside China with VOOC?
Super VOOC is 50W, the same like Huaweis SuperCharge 2.
Did you test SuperCharge 2 or VOOC?
My OP6T charges up to 100% in 1hr 22mins, so I don't charge overnight anymore. Go to sleep on 40% and charge in the morning
The combo of battery life and crazy fast charging is for the first time breaking me of the "plug it in overnight" habit that I have had since my first cell phone over a decade ago. I can keep my charger at my desk, plug it in for half an hour, and be at 100% with almost no chance of running out before the next morning. That means fewer vampire chargers around the house wasting power, and fewer charge cycles lost leaving the phone plugged in long after it's full. I wish I had swapped to OnePlus sooner - I think I have finally found a phone maker to call my favorite.
The charging Speed with "Dash charge" is amazing.
Within few minutes the battery is from 0% to over 50%!
Generelly I can only say: Amazing battery life. The best I ever had with a phone (except Nokia 3310).
I started to charge when the battery was 5%. It took around 1 hour 20 mins. I can say this to be quite faster when compared to the devices I have used previously, that too when the size of the battery is much bigger than the previous phones.

I wish I had swapped to OnePlus sooner - I think I have finally found a phone maker to call my favorite.

The incredibly fast charging, coupled with the insane battery life (especially in dark mode) has made me totally OK with no wireless charging. I used to leave my phone on the charging pad at my desk most of the day, and on my nightstand charging pad overnight. I never had to worry about charging at all and plugged in maybe 20 times max over the last two years with my Note5. I said I'd never buy a phone without wireless charging, but the $350 or so I got for my Note5 exchange for this phone was just too tempting to overlook, particularly if it set up my family for the next two to three years (our current phones didn't have band 71 and Samsung said no more security updates). The only thing I was really worried about was wireless charging and whether or not the battery life and dash charging would be enough for me to overcome range anxiety.
It has.
So I'm thinking of keeping my dash charger at home ,and my 30w aukey charger at work ,I take it this will be ok to use ?

It should be. If you are starting from full in the morning I doubt you will even need the charger are work except for very rare instances. I have gotten 7 hours SOT that was mostly gaming on this thing, moderate use you can easily get 24 hours, light use around 48.
As we all know, the charger xiaomi provided in the box does not support fast charging, although it is quite good. For fast charging we have to use different adapters or powerbanks that support it.
Yesterday when I was using my normal charger, it suddenly showed quick charge and two lightning symbols in the top right corner, which indicates fast charging, that I usually get when using my mi powerbank.
First I thought it was a software flaw but sure enough, my phone was charging at a much faster rate and was heating up similar to when I charge using powerbank.
Unfortunately when I removed the charger and reinserted it, the phone charges at it's normal rate, and I've been unsuccessfully trying to repeat it but it's not happening.
My device is completely unmodified, stock unrooted rom and bootloader locked.
I think this means that the normal adapter might be capable of fast charging but xiaomi has disabled it, something worth looking into.
Also I know the phone charges quite fast below 50%, I saw this effect while phone was at 69% and reached 72% in barely 3 minutes or something.
Unfortunately I did not have the presence of mind to take photos as proof.
first of all if you are using charger which comes in box with the phone, its not a fast charger its only 5V2A.
2nd it can't charge at pace compared to fast chargers as it can only provide 2A at max or it may be faulty
3rd it may be software bug just showing quick charge
and in the end you said it charged from 69 to 72 in 3 min. i can say its not fast charging because my charger 5V2A which came in box also charges at same speed you are saying. it normally takes around 1 min for 1% increase but depends on various factors like load being used currently by the phone.
sometimes when data is off or battery saver os on it charges more quickly as consumption is also less so it charges fast.

It was 2% in one minute, I've attached a ss from telegram group of violet where I reported this for proof. My data and wifi were on, and I've enabled always switch on data for faster switching in developer settings.
Even now it's currently happening, but the rate is very slow, I think it's probably a software bug like you say, any idea why this is happening?
Edit 1: That Telegram ss is from the day where I first created this thread, not today.

i know the time is different but why didn't it increased in screenshots you uploaded the time already changed in both of them but battery remains same 69%. its showing fast charging but its not working I guess
plus maybe your battery health is not good.
