This chager charges my phone from 4% to %100 in exactly 3 hours.

So I just ordered this charger and it charged my phone from 4% to %100 percent in exactly 3 hours!

Wow, what a great improvement over stock which takes 6+ hours. This makes me believe, that even though the stock output is rated at 1000ma and this charger's output is only rated 700ma that this charges works correctly!
If you have a 1800mah battery and you charge it at a rate of .7A, it should take it exactly 2.57 hours to charge, (1800/700). With stock it should take less, because 1800/1000 = 1.8 hours, but it takes 6+ hours to fully charge! Something is f'ed up with the stock charger or phone's software...

Yeah. About that. I just got my E4GT yesterday and noticed it does charge extra slow compared to my O.G. Epic.
My wife stayed with hers, maybe I will try charging my phone on hers. I wonder if that would make a difference...

I use the Palm charger from my TouchPad. Will go from dead to fully charged in about an hour and a half.

What's you TouchPad charger's output in mah? I think I might have to splice into a spare USB cable and check how much current is actually used by phone when on stock charger...pretty sure it is nowhere close to 1000mah.

2000mah is the output from the TP charger.

According to BatteryMonitorWidget, it estimates avg mA charging at 270mA using the stock charger that came with this particular phone.

I have my original charger from my Evo 4g and have noticed that it charges my phone a lot faster then the stock one that came with the phone. :-( weird

That sounds about right! I'll see if I can test this with my AMP meter tonight and tell you all for sure on stock vs new samsung charger that I've got.

Yeah, at 2000mah it should charge in less than one hour...I would say your actual charge current to be around 1200mah...

i would be careful with these chargers.
i have dealt with a lot of Li-Po's in the past and there was a formula to how fast you should charge them.
i imagine it is the same deal with Li-On.
charging outside such formula could kill the life of your battery or worse.

Seems like i must have gotten lucky as a ton of people are having problems with their phone or chargers.
I just charged my battery from 0 to 100% off the stock charger in 2 and a half hours and i also havent gotten any of the dodgy input problems using the phone while charging.

I went back and took a longer look at the battery history when charging. When starting the charge at 65% it starts off around 828mA, then 540mA, then 360mA, so it looks like (as expected) the phone knows how much current to pull to charge the battery safely and it adjusts based on how full the battery is. Not saying it does this for the charger included with your phone, but that is the behavior for the charger included with this phone.
These are all estimates provided by Battery Monitor Widget because there is no real-time mA current meter in this phone (according to the author)

Ordered one of these. Stock charger takes a lifetime to charge the phone.

My GF got Nexus S 4G and it's stock charger also takes 6+ hours to charge, so there's something wrong with the chargers I guess...

The pins on this charger must me different than the stock charger. Just because the stock charger is rated up to 1Ah doesn't meant the phone or batteries circuitry allows that much output. The resistance and length of the USB pins on the cable are what determines the output of the charger. Simply using a different USB cable with the stock charger will get you faster charge times.
Using a 2Ah charger will get you nowhere, the circuitry doesn't allow that strong of a current. Just a bit of an FYI. Save your money and save your phone, use a different USB cable.
Also, how is the charge time holding up? I doubt you're getting a saturated charge with that charger.

Ive dealt with 1,2, and 3 cell lipos ranging from 150mah to 5000mah, and every one of them either say to be (or ive been told its recommended to do so) charged at 1C. so a 500mah battery should be charged at .5A, 1000mah at 1A, 5000mah at 5A, etc...
my lipo charger displays a bunch of info as the battery charges and it definitely drops the current as the battery gets closer to being fully charged. if its the same with li-on then I would imagine that .18A should be the most you would charge this battery, but Id rather it take a long time because unless things have changed recently, doesnt the slower you charge the battery prolong its life cycle as well as extend how long it lasts each charge? I only charge mine at night when I am sleeping so who cares if it takes longer than an hour. if I get into an emergency situation I have the cig lighter charger and in the worst case I even have one of those crank flashlights I can use to charge the phone in the event my car battery shorted out or something...

Good Quality and Quick Spare Battery Charger

I have an LG Lucid which isn't half bad. Unless you factor in battery life.
So I'm ready to pull the trigger on a spare battery or two, as well as a wall charger. You know those ones that you plug the battery into itself.
Anyone have recommendations on an inexpensive, decent charger that will charge a 1800-1900mah battery within maybe 6 hours or so?
Thanks!
Oh- looking on amazon if I can, as I have a gift card.

I just did this for my S3.
I can't recommend one for your phone, but once you know what to look for, it's the same basics across all batteries and chargers.
Do you want it to charge slowly ? You say 6 hours, but that seems awfully slow to me. Is that the point - so you can leave it on overnight ? I have a charger that chargers my 2200mAh battery in ~4 hours.
Look for a charger that will charge at 600+mAh. Often it will charge faster if connected to USB. You want to avoid the ones that charge as slowly as 300mAh. I guess they're good if you want to leave something overnight, but they're going to take ~8 hours to charge the battery !
Anyway - no matter if you want it to charge fast or slow, just look at the mAh output and do the math compared to your battery capacity - you can even use a "calculator" that will do the math for you (but it's really easy - "2200 / 600 = 3.6" - so 3.6 hours, but with some wiggle room for lower than 100% efficiency).
I got mine from the brand Anker - they were one of the few that offered a charger that wasn't ridiculously slow. It's 600mAh from an outlet, 1000mAh from USB (meaning it could charge the battery almost twice as fast). It came with two spares and the charger. All the reviews I read didn't say great things about the "universal" chargers, and they all seemed to have lower rates of charging - but maybe I wasn't looking at the right ones.

Correct way to charge 5X

Had a Nexus 4 and I did the overnight charge,
Is it the same for the 5X with the rapid charge?
Thanks
Gary

There is not a better way to do it, you can rapid-charge it overnight, during the day, in you car, every 3 minutes with 10 minute pause or whenever you would like to.
For me, I use a normal charger overnight and the rapid charger when I need juice during the day or in the car, or when i forget to plug it overnight.

I remember reading on a reputable tech site about how lithium works, you can leave it overnight with no issues but they have a specific amount of charges in them. E.g. 500 charges for a battery and a charge will be counted anytime it goes above 80% etc. After 500 times, your battery should start to see degradation.
All the above figures are made up but that was the gist of the article i read, so don't worry about leaving your phone plugged in, the os will automatically limit the charge once it reaches 100%.

Google's take on the subject:
Battery lifespan, charging & usage tips
Good charging practices and care can increase your battery's lifespan. Use the tips below to keep your battery healthy.
6 battery charging & care tips
1. Use the power adapter and charger that came with your device
Other chargers can charge slowly, not at all, or damage your device or battery.
2. Keep it cool
Avoid situations where your device can overheat. Your battery will drain much faster when it's hot, even if you're not using it, and this can even damage your battery. Keep in mind that your device warms up when it's plugged in, so try not to keep it charging all the time.
3. Don't worry about calibrating the battery
You don't need to teach your device how much capacity the battery has by going from totally charged to completely drained.
4. Keep it more than half charged
For the best battery lifespan, try to keep your battery charged above 50% as much as possible.
5. Try to charge a little at a time
Small charges throughout the day are best for battery health. Battery lifespan can suffer if it's charged from zero to full and then completely drained on a regular basis.
6. Store your device half charged
Leave the device with a half-full battery if it needs to be stored for a long time.

Is it possible to turn off the dash charge?

Hi,
Is it possible to turn off the dash charge? 5T is charged only overnight cause it can last the whole day anyway.
PS: I can turn off Fash Charge in my Samsung Note. So it saves battery if I charge only overnight and don't need fast charge feature.

There is no stock option for this. Maybe a custom kernel can support it or a custom kernel that doesn't support it at all would also be a possibility in theory.
I would suggest using a normal power adapter instead of the Dash charging one. Even a normal USB C cable prevents Dash charging as it can only be used with OnePlus' own cable. So maybe get a cheap USB C cable and use that?

Use a low amperage charger. Something like 1000mah. This will slowly charge your phone overnight. But make sure you use a quality charger.

Why would you want to do this? The OnePlus dash charger works differently from other chargers in that it holds the heat in the charging block. If you use a standard adapter you would transfer the heat to the phone while charging. I would NOT recommend doing this.

I use an Anker IQ 6-port Charger with a couple of fairly good quality cables.
I personally try to avoid any kind of fast charge because it will end up damaging the battery life faster than "standard" charge, even if the heat is absorbed by the DASH charger block. IQ Charge adapts itself with the needs of the device connected.
And my unit stays cool if I touch it while its charging.

Charge however you want. But for me, dash charger while getting ready in the morning or when you have a free half hour. Forget about charging overnight. I don't know your usage but for me, this works. The phone just sits on my nightstand without connecting overnight and I lose a very minimal battery amount.

It's fine at even less than 1 amp. We have two 5Ts in the house and charge them at night at 0.35 - 0.45 amp.

I saw the dash reduce Ampare when pass above 80%.
(When not rush I use official iPhone 1Amp charger.)

Use 5V/2A standard charger to standard usb type c.
Oneplus 5t = 5V/4A
Quick Charge = 9V/2A
Dash n QC have more power!

I'm using an old 1A Samsung power adapter and dash charge cable and in addition I also use Battery Charge Limit app to limit charging the battery to 80%.

No, it does not, especially not with dash charge. The excess heat is stored in the charger and is not transferred to the phone, and the heat is the only thing that degrades the battery faster.

Your informations are not correct.
Dash (or VOOC, which is the very same technology since OnePlus is an Oppo brand) uses high current fast charging instead of high voltage charging (QuickCharge 2.0/3.0 uses high voltage) and the circuit that produces heat in phones that are not Dash/VOOC compliant is inside the phone, while in Dash/VOOC is inside the charger.
Oppo and OnePlush themselves have acknowledged that it makes SAFE to use the phone while it is quickcharging, NOT that the battery is not getting damaged by the use of a fast charging method, even if it charges at a lower voltage and higher current.
The use of any fast charge technology implies to shorten out the overall battery life.

Just because they moved a bunch of the power regulation stuff to the charger doesn't mean the battery doesn't still get warmer. If you push 4 amps of current into it, it will heat up more so than when it receives, 1 amp.
Now you have me curious though, I guess I'll have to pay close attention to the battery temp next time I charge my battery. I've never used the dash charger, but perhaps I'll have to get it out of the box, and test with it as well just to see what kind of temps I see with a more powerful charger as well. I'm curious to see how much temperature difference there is.
I know on my Nexus 5X my phone always lasted long on a single charge when slow charged (0.35 amps), vs using the factory 3 amp charger.

Constantly topping up the battery overnight for 5-6 hours (assuming your slow charger will charge it to 100% in 2-3 hours) is worse than using Dash to charge it quickly in bursts in the morning and night when you have a spare 30 minutes.
I would never leave a phone stuck on a charger overnight. Especially since even the slowest charger in the works will charge the phone to 100% in three hours or so.

I don't charge my phone over night either but by using above mentioned Battery Charge Limit app it is possible to stop charging when desired battery level has been reached.

That would be a good idea to do. Although the best is to just Dash charge in short 30 minute bursts when you can.

How does it imply that? Heat is the only factor. Phone is not getting hot(ter than slowly charging) when charging.

What is the truth? With the rapid charging the battery deteriorates faster or better a slower charging?

Wall Charger 1Amp or 1.5

Hello guys,
To offert at my battery the best treatment I'm looking for a lower amperage wall charger for my Pixel 2XL.
Between 1 and 1.5 Amp it will be excellent. I read some interesting suties about battery life and how manage it and fast charge is part of that.
Thank you all anf have good evening.

I am sure it will charge on either one, but how fast who knows? If you are rooted and have Magisk, download the ACC module and you can control your charging that way instead.

I am an electrical engineer, and have some knowledge about how Li batteries function.
I have always wondered this, I always see people mentioning that slower charging is better for the longevity of Li-ion batteries. There is always a trade-off here. Slower charging also means the battery takes much longer to charge, and the battery stays hotter for longer period of time, which should affect it's lifetime. Fast charging also does the same thing, but the temperature is much hotter but is exposed for shorter period of time.
Now these is merely a speculation on my part, I don't have any theoretical or experimental evidence to back this up - I think regular 5V 2A charging is a balance between those two scenarios.
Also, I recall that the peak charging current is limited in P2XL, so using the stock charger shouldn't harm that much either.

Pixel 2XL is my first smartphone who do not Come hot when it charge so...
But I know that high temperature are not the best things for battery in general.
And about the level of charge ? Some people said they stop at 80% to manage battery

I use a 5 watts charger and the phone stay completely cold during the charge process.
Also there was a recent 2017 scientific paper that tested what degraded the battery. It's a really interesting read with many tested model.
https://www.researchgate.net/profil...e-model-under-different-charging-stresses.pdf
Number 1 cause is high battery voltage at the end, second one is battery charging speed. Any speed faster than 1c will degrade the battery much faster.
This is why i charge at 5w plus stop charging at 80% (unless i know I'll need 100% that day, where i fully charge, but for my usage 80% is more than enough for the usual day).

I download AccuBattery and charge my phone from 25% to 80% max. The app detect directly the stock capacity of my battery (3520mAh) but after my charge, the new capacity estimated is 2982%. Is the first value is reliable or I have to do some other charges?

You have to wait for about 10 cycles. It says in the application something like that.
