Hello everybody,
to begin with i must say that my phone's battery used to take 2 to 3 hours max to charge from wall charger but now since i flashed the ROM and it has been acting so weird when charging. I have monitored the charging time and found that
after 1hr the battery goes to 50 %
after 3 hrs its up to 70%
after 5 hrs its up to 89%
then after being on charge for 6 hrs its fully charged !!!
p.s the battery lasts the normal time it used to.
so what's going wrong here?
your help is much appreciated!
You're using the same charger right? I believe aftermarket chargers are slower and suck!

Yes its the same original charger!!
The only suggestion I have now is to double check if it's really because of the rom?
Try using another rom for a day or so and see if it also takes you that long to recharge. Don't restore apps or anything yet either! (could be an app causing it, however that's unlikely) Mine only takes long to charge if I'm using too much stuff while charging it.
It is normal. Charge voltage is lowered when reaching 70% (or 80%, you can check it at battery stats) and then even lower when almost full until it is really 100%, not to harm the battery pack. Your previous cycles only semmed faster, the more you use your phone the better your battery stats will be.
If you wiped battery stats before, it could be another reason for strange figures.
Most importantly, if you want to have a good battery life on the long run, dont fully discharge/charge it.
I don't use my P6200 a lot I have to say, so I do charge it to use it but leave it to run out of battery. The problem is such, that, when I charge my tablet from flat, it takes such a long time even to show the charging icon. Has anyone experienced a problem similar to me, and how they have dealt with it?
It would be nice to have a script which causes the tablet to shutdown at 10% or something like that. That gives enough energy to start up the charger icon.

Yes this is a normal the easiest way to prevent this is to feed you kid/s (device/s)before you store them, Why does this happen? Your battery is simply below the min boot voltage/ is critically low
eg. you have a 3.7 volt 4AH battery at 100% its 4.255volt at 0% its 3.145volt if you let it run dry 0% and store it and it falls to for arguments sake to 2.9 volt then it is below the min voltage and it will take a while to charge to requiered voltage as with all batteries
Please not you will get better battery life from your device if you charge it more frequently and not run it down to much.
My tab has been serving me a a phone for 28.5 months calls from 8am to 5 pm and games from 7pm to 11pm almost everyday my device was was built 2012/05 never needed a replacement battery pack so far and still get 4-10 hour use if i deep discharge over weekends
More info if you run a device dry
Please keep you OEM charger close as mine ran dry and "locked itself"(this is what the samsung tech said) and i tryed a S3 note2 and note 8 charger for 30min +/- each with my oem charge lead and it denied to charge only the orginal charger worked in 1min i was up and running ... was a worried device was 4 weeks old
Thanks very much @matthys
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.

Will definitely try that out. Cuz my usage gets me around 4 -4.5 or even 6 if I read a little. So if this happens for me too I'm gonna get some nice battery life.

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.

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.
I have a theory...maybe it was a fluke or maybe its true. I have a 3 year old phone, which I owned from new and has had hundreds of charging cycles, but still has 99% battery capacity of a brand new phone according to both accubattery and measuring with plug in monitor. I've only ever charged it via computer usb 2.0 which is max 500mah.
I've bought some used phones which were only around 1 year old and had just 70-80% capacity left, and yes they supported quick charge. I honestly think the main thing which reduces battery capacity over time is not charge cycles, but charge speed. Ditch the quick charge if you want to keep your battery capacity!
The main thing which kill the battery is the temperature.
And charging faster takes to higher temperature.
But there're some way in the middle.
Charge my 5000mah battery at 0,5A would takes around 3 hours...
Also it should be better charge till 80% not till 100%.

The issue is I think most people have a habit of using their quick charger at night, when it is not needed. You sleep for much longer than the phone takes to charge, even with 0.5a speed. The only time there is a benefit from quick chargers is during the day, but how many people really need to charge during the day if they start with 100%. Some people might never charge during day but still use the quick charger at night.
I think Apples recent change in IOS is more proof of this, so they keep the phone below full charge for a few hours before eventually filling it up. Phones are now charging too fast to the point that battery capacity is reducing noticeably in just a few months of use.
If you are someone who just charges overnight, replacing the quick charger with a slow speed one will definitely help maintain the battery capacity.

I use my phone a lot, also for hotspot often, or when I travel for gps and maps.
(yeah maybe I'm a bit too dependent but still...).
And fast change is my useful.
Anyway Asus set a smart charge mainly trying to optimize the charge speed depending from your habits (with kind of AI).
So if you put in charge during night it should charge slower.
Also in a phone of 3000mah at 60% is kind of not usable. Not the same on a phone with 5000mah.

I'm not saying fast charge is bad, for sure some people can benefit... but the fact my 3 year old phone still has 99% capacity after 3 years and hundreds of charge cycles, and was only charged at maximum 500mah kind of proves that the key to keeping battery capacity is slow charging. I didn't do anything like try to keep it between 40-80% etc, the phone was very often drained to 0% and left at 100% for long time, but still it has retained almost 100% capacity. It must be the slow charging which helped keep such high capacity.

My 4-year device has 3300 mah and it has close to 90% capacity as well.
I think bro, that longest devices are those devices we dont care for.
If you care too much about baterry, it will "drain" faster, and "lose" capacity faster than usual.
Yea, i would agree that main thing which kills battery is temperature, and if you charged that 3 year phone from a computer slow charger, it means it wasnt your daily driver, and it wasnt neccesary.
So you didnt care when it reached 0%, you didnt cared about phone at all, you used it most probably for testing purposes i would guess.
And liion wear out by itself even if you dont use it, if you buy it new and fresh, and store it for 10 years, when you power it up, it will be dead long time, liion chemistry is active and can keep for 5-10 years, no matter if charging or idle, it will bubble up over time, and also if used, from temperature.
I own a new tablet (2 years old now), was amazed with battery, and tought myself (wow, how much i can do with this long lasting capacity), and i unlocked it this summer to custom ROM and full CPU speed all time, readed many books and learned from it, because of strong light in summer, screen was always near max so i can see, and i could feel a strong heat from where led is in lcd, and where CPU is, both sides were frying, i didnt holded tab in hand, i attached a mouse to it, but when i touched screen, it really felt uncomfortable for me, and could feel mild fry on my fingers (i remmember one time, i really burned my finger a little bit, i touched where CPU was), and imagine how much impact it had on my battery.
Even, most of the time, i kept plugged in, day and night, when i am not using it, i always keep it in charger, because i am lazy and dont want one more worry.
And guess what, it still goes good, but still i saw big decrease in capacity.
And i dont worry about batteryes anymore. I keep wifi always on, even when i when not in reach, i dont care, because it is much easier to just plug it in when you can, even when you wake up and see a 10% battery, it is enought to plug it in a charger, so when you go into a wc, and be ready for day, you will have 45%, enought until you go to work, then you can continue charge it. Or even better, buy a battery charger and never worry again.
It's meant to be used, and no matter what you do, it will last 5 years or a little longer, but of course best capacity is at 2 years.
