Hello
Lately( a week or so) I have been noticing that my phone is taking longer to charge. Before the charging took about 1.5 hours maximum from wall charger. Lately it takes more than 2.5 hours!
I took my charger and checked how much mA it was giving. The range is 770 to 330. On my Nexus if I use the charger, it gives stable 770-750 mA. So I'm sure its not the charger. Nexus 2.1A charger gives 900-980 mA if I use it to charge my Xperia but I'm afraid it might damage my phone.
I know as the battery is charged, less current flows and thus the value starts to drop but why suddenly it is taking more time to charge ? How much heat can affect it? (Really an extra hour if I place it over my microwave which is always off when I'm charging but it is sometimes it's a bit warm.)
Funny thing is I charged it at another plug with same result.(2.5 hours) but sometimes my phone surprises me and charges within 1.5 hours. I can't seem to find out why

I even tried by switching off the device.
Hi all! My Pixel 2 charges fast(~2700mA) up to first ~20%, then the current changes to 1370mA till almost to 90%, then slows a bit till the 100%. I have used Ampere to check the charging speed. I expected the phone to charge to at least 50% at a fast rate, then slow down a bit.
I recently acquired the device and it had May patch, but then after setting the device up, it prompted me for June patch and I installed it. Don't know if the new update could be the problem.
The phone will take battery temperature into account as well. Do you have a way to monitor that and correlate it with where the current switch points are?

I charge my phone early in the morning where it was not used all night. No battery drain apps at all. It just charges from almost 0 to 20 percent really fast, but then slows to a steady 1370 mA.
What I mean is ... Try charging from a different start point.
By the time it's charged at 2.7 amps to go from 0 to 20 it might be getting warm. You might try charging when it's at 20 and cool and see what happens. Or stop at 20 and let it cool down before going any further and see what happens.

So I did some testing and here is what I see:
Phone starts to charge at a good 2700mA rate for ~ a minute, then slows down to 1370mA. It doesn't really matter if phone has 5% of battery before I start charging or 20% or 40%, the charging pattern is the same. At start the battery temperature is ~32 C and when it charges at 2700 for that first minute or so, the temp rises to ~36 C, then phone drops the charging rate to 1370. Phone is pretty much room temperature and not hot or anything like that. I have 2 Google chargers; One is from original Pixel and the other is from Pixel 2 box. Both do the same thing and charge at the same rate.
There are no abnormal app activity or any battery drain. I am using Ampere app to check mA. Did anyone come across this?
It appears you've discovered the magic battery temperature cutoff that HTC has selected for the Pixel 2 ... and that seems to be around 35 or 36 degrees.
For every 10 C rise in temperature, battery degradation doubles by almost every measurable metric. It doesn't surprise me that at around 35 C your phone appears to limit the charge current ... seemingly to avoid making the battery any hotter. Taking the temperature higher for the charge cycle (or for any other reason) will degrade the battery over time. Deep discharges toward zero also reduce the life of a battery. (Keeping it at 50% or higher is recommended for lithium-ion rechargeable batteries.)
If you can cool the phone down to 25 C before starting to charge, I'd be willing to bet that it will charge at the higher rate for longer. Maybe put a small fan on the phone or set it in front of an A/C vent while it charges and see what happens then.

That is interesting as I have had different phones which got even warmer than Pixel 2, but still charged at a good rate. I do know that after 80% of charge of so, the charge rate does go down, which isn't a surprise to me. I just picked up my phone, after it was sitting idle for few hours and see that battery/phone temp is 25 C. I will make sure to start charging phone at a low temperature and see if it will keep the fast charge rate longer.
What you mentioned about the "keeping battery at 50% or so). Did you mean that when battery goes down to 50 or so %, charge it? I usually run battery until about 30 or so % before charging it.

Yes, charging it when it gets to around 50%, based on a number of studies, seems to be the way to go.
Deep discharges and hot temperatures are enemies of battery life for today's lithium-ion cells.

I have tried just now to start charging the phone when it is 23 C, but still get the same result. Could it be the June security patch?
Update: So the phone charged by rate of 1370mA from 22% to 100% in 1h 25m. So going from 0 to 100% should take ~1h 45m? Can anyone confirm how long it takes to charge Pixel 2 using original charger?

Go a reference to these studies?
This app vendor has seen a lot and isn't convinced discharging to low values has much material effect on battery service life. Charging to high levels does, however. Interesting read I think... with commentry on the often quoted Battery University pages. I agree that heat isn't good whatever.

I can't point to anything peer reviewed or funded by the NSF ... so maybe 'studies' is the wrong word.
I've seen the Battery University articles and they've seemed believable to me. It's possible they're flawed. I've also seen articles from these guys - https://www.mpoweruk.com/life.htm ... and other tech writers who corroborate such claims. I've also seen the claims about the high level charging you're pointing to and some who suggest you should keep your battery between 50% and 85% all the time to get the most out of it.
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.

no gaming(not a mobile gamer)
Charging are so slow it tooks atleast 2 hours to get full charge, and is not acceptable. What year is it? 2016? My other phone with lower price than this can perform 35% faster.
Pretty fast, especially when using QC3.0 charger.
0-80% is fast, but 80-100% is pretty slow in my opinion. It's a good thing tho, makes the battery last longer.
Fast charging should refer to the initial phase. If you plug in for 20 minutes it should give you enough power for atleast 5-6 hours. Sadly, that is not happening over here.

Some people here say that their device takes longer to charge and all. I say there a some important factors to consider -
1. Heat of the Device - How hot it was when you put it on charge. If it is hot, then definitely your phones regulator will reduce the amount of charge let into the phone.
2. Ambient Temperature - If the climate is hot, then automatically fast charging will increase device temperature. And as Black color absorbs more heat energy phones temperature will naturally be more than in a chilled room. (All phones are susceptible to this phenomenon, I've Experienced this first hand) and more heat = low speed charging
3. Power Outlet - The power outlet at which the charger is connected also plays a very important role. Pretty Self explanatory.
My Phone takes around 1:40 - 1:50Hrs at normal temps(ambient and device), while 2:30Hrs in a very hot condition.
too slow , it takes me over 2 hours to 25% to fully charge
So I bought POCO X3 Pro earlier this month...So I play games on it mainly and the question is which kind of charging habit is better?
1.Frequently charging to make the percentage between 50%-100%
2.Charge it to 80-90 and try not make to make it fall below 20% and charge only once in a day?
The second option is a bit far fetched for me...Though I will try
My habit is 1 + 2: when around 50%, charge it up to around 90%.
Of course I'm not paranoid about it. But I do check battery levels most times I pick up my phone, to decide what to do.
If you root your device, you can use Battery Charge Limit.
You can set the maximum charging percentage, like setting it to 80%, then the charger will stop charging.
For our POCO X3 PRO, we need to go into this app setting and change "Set Control File" to the one with mi6 or something I don't clearly remember.
ArrowOS has this smart charging built-in.
I personally use my old charger to charge it slowly.
From what I observe, the Xiaomi 33W charger will rise the battery temperature to 40°C, which is bad to the battery. My slow charger will increase to ~33°C.
The fast charge is for convenience and emergency eg. forgot to charge at night and need to rush in the morning.
Frequently charging between 40~80% is better for battery health in long term.
Advanced Charging Controller (acc) is a good module to do this under control. It also has links about battery health explanation. (Battery university)
It is best to keep it between 20-80 present and not gaming while charging. I use my old slow charger when i am not in a hurry.
i keep mine at 70% max. i charge when it gets to 40%. I use arrowOS so i can set max charging and it resets the battery stats as well, so i know which apps eats power next time
Trying to keep it between 40-80%, with 10min break before recharging to cool down
Actually, I always keep my battery between 25% and 75%, then I restart the device once a week. Finally, I will use it until 0% one or two times a month before charging fully to 100% , I have read in a newspaper, it is necessary for digital devices.

If you want your phone battery health to last longer for years, like 2 years or more, then it's better. Info is here: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
For long term, battery will degrade and loose it's capacity, so your battery die eventually, then replace, then die, then replace...

If you are wealthy enough to change your phone so frequently that you don't even want to concern the long term damage to phones, then forget about it and go for the TOP. (And coffee for me )

To be honest, I wouldn't worry too much about any loss of capacity in the battery. My oldest still active device is now 5 years old and even with that I do not notice any significant loss of capacity. Typically all of my devices charge from around 5% to 100%. My Nokia 7 Plus was charged almost daily by me for 2 years and by my brother for a year before that, but I don't know how he charged it. Still, I haven't noticed any change in the running time to this day.
Maybe it's not the place to ask, but I was wondering, is there any way to know if a Xiaomi charger is fake? I want to buy a charger between 10-18w to replace my 33w charger in order to reduce my POCO X3 PRO battery's suffering, but I live in a third world country where is VERY difficult to adquire imported products and I don't want to buy a fake one from the local online marketplaces, if you guys could please help me I would appreciate it

If you have a laptop, use it's USB. It most likely will charge VERY slow, to the point that you want it to charge faster.
Edit: The alternative way is to use Magisk module Advanced Charging Controller (acc)
You need to unlock bootloader, install Magisk, and install Advanced Charging Controller (acc) module.
Then you can restrict the charging current or voltage. I tried with the official charger and it can be charged below 500 mAh, so below 2.5 watts.

All interesting posts. I wonder however:
What about having the device connected to the charger most of the time (at work place) with 100% most of the time, so it is de-charged only a small time of the day? So only at times when really moving around some workdays or in the weekend the device gets down to 20% or below.
I have now changed the 33W (12V/3A) Fast-Charger with the older 18W (9V/2A) Charger of the RN7 I have.
Would setting the charge limit to 80% give a huge benefit if I would like to use the device at least for 2-3 years?

What about having the device connected to the charger most of the time (at work place) with 100% most of the time, so it is de-charged only a small time of the day? So only at times when really moving around some workdays or in the weekend the device gets down to 20% or below.
I have now changed the 33W (12V/3A) Fast-Charger with the older 18W (9V/2A) Charger of the RN7 I have.
Would setting the charge limit to 80% give a huge benefit if I would like to use the device at least for 2-3 years?

Connecting to the power all the time at around 100% is bad. It is at the limit of Over charging, the battery may bloat up and destroy the screen.
If you want, it's better to set it limit 40~80% and connect. The importance is the battery temperature. Don't make it hot. You can check it with Ampere.
The benefit is about the battery. You might not need to replace it often when you encounter like cases of sudden drop of percentage or sudden shutdown.
Huge or not is subjective.

Regarding battery temperature at least after reaching 100% I never noticed a hot or even warm phone.
I taught the device/system has some "charging intelligence" when always connected, so that the phone is directly using the power from the cable while the battery is not drained?
In Stock MIUI (debloated) or xiaomi.eu without root it is not possible to set a different Battery Charge Limit then?

When it's about to reach 80% or 90%, smart batteries now will charge slower automatically, so you don't feel the temperature.
However, when you see it in ultra-fast charge, like 40% charing to 70% in 30 minutes, the battery rise to 40°C or higher (as I observed.) Can even go higher depend on climate and using while charging.

This can be done with Advanced Charging Controller (acc).
I had answered similar questions here:

This control needs root.
Unless it's built into the Rom.
ArrowOS version 2021-05-07 had Smart charging that can set a limit threshold without root.
But developer said will remove this funtcion. See in his Rom thread for his reply.
