Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V20 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

I use Ampere to see the rate I am getting. First plug in might only be 90 mah. I unplug, replug, it jumps up to 350. A couple more times and I end up at 900-1200. Screen off and let it fast charge.

I recently tried out the HTC Bolt for a couple weeks and it seemed to charge much faster than my V20. Shouldn't it be the other way around since the Bolt uses quick charging 2.0 while the V20 uses Quick charging 3.0?

Slowest charging phone i ever owned but i still love it lol

My H910 charges relatively quickly. Just plugged it into a quickcharge 2.0, not 3.0 car charger and it went from 16% to 50% in ~25 minutes.

I regularly get rates of 1.8A or greater using a CHOETECH or Anker charger. One its above 80%, it drops down, but this is normal.
The Anker is QC3.0 and the CHOETECH are QC2.0

agree, LOL
even my old G2 get 50% battery in half an hour.
what's with V20?
it uses QC 3.0, but charge slower.
I use original V20 charger, and when charging the status is "quick charging.."
it takes 2 hours from 27% to 100%
:sad

looks like something really wrong with your phone. My phone usually takes about 75 mins to charge from 0% to 100%

maybe, but it looks like not just me though.
and btw, my LG G2 can do full charge in 1 hour and 20 mins (80 minutes), and it's not even QC 3.0
I read somewhere in gsmarena, QC 3.0 should charge to 80% in 30 mins

not sure about G2. I've never had one.
QC 3.0 might be able to do it technically, but I've never seen a phone that fast in charging yet. Not even the OP3T which every body is saying quickest in charging.

Hmm.. okay.
How about your G Flex2? how long it would take to charge to 100%?
G Flex2's battery 3000mAh, right? Same as G2

That grandpa tooks around 2+ hrs to get full charge
But to be fair with the phone, I've never used the original charger of G Flex 2 to charge. I either used my old chargers from previous phones or I plugged it into my laptop to charge it. Let me find the original charger and try it when i get back home

Great
Very fast charge

Delete please.

I have absolutely no complaints with the charging speed. Also, I rarely drop below 40%.

My battery takes forever to charge up!
I just bought a VS995 Verizon Unlocked off the net. Was classified as "almost new - open box", hope I did NOT get a unit with problems. Re-charged it now a total of 5 times and on average (plus or minus 3-5 minutes) it takes approx. 3 hours and 18 minutes. for a full charge 0% to 100% . A few thoughts and questions came to mind while reading all your excellent posts:
1.) I believe he must of lost his quick charger because the one he gave me seems like he bought it off the net. Standard USB charger. So probably not using the quick charge function feature of this phone correct?
2.) Can I goto an electronics store and just copy whatever voltage and amps I need to perform a quick charge? Can someone please POST what the voltages and amps needed for a quick charge 3.0 please.
3.) Anyone have a bad battery or have one go bad after using the wrong charging devices? I was thinking of ordering a new battery BUT they are a little pricey. Anyone know some good outlets to buy them at a fair price?
4.) Does rooting the device and putting one of the ROM's on their cell solve anyone's battery problem? If so which ROM do you recommend?
Overall that is my only gripe about the phone. I love the DAC and for all you music lovers out there try Sirius XM on the LG-V20 and make sure to use Hi-Fi made headphones. I bought myself Bowers and Wilkens P7's, sort of pricey but worth it to me. The other thing is Napster as well the songs you download sound awesome with this DAC. For both of these APPS make sure you go into settings and adjust the quality of the downloads and streaming. Otherwise you could be listening to it with poor quality settings from the get go.
Ok well I appreciate any help or advice on my battery situation!
Thanks in advance to anyone helping me out.

Any charger that says Quick Charge 3.0 would work. I think even QC 2.0 would charge at the same speed, but just less energy efficient.

The difference between qc 2 and 3 is 3 has a variable voltage allowing it to use energy more efficiently.
Excess energy is lost as heat on qc2, the power is reduced in qc3 when the battery starts to get full.
The charge time is the same.
Specs for QC 2 is 5V / 9V/ 12V, specs for QC 3 is
3.2v - 20v dynamic

Fastest with dash

i heard that this also works with usb power delivery (maybe out of the box or with a custom kernal?) which is good news. an open standard fast charge framework is always a good thing.,

I got 35%---> 80% in 25min ish this morning. powered on, off screen

So fast like sanic :laugh:

Insane Charging speed even without dash charge

Easy from 40-80% in 20 minutes every time. I rarely every have to let my phone dip past 70

If you plug it into a quick charge 3.0 charger, how much time does it take to charge it fully? thanks

i wouldn't say as quick but quicker. if you want dash charge style speeds you would need a Quick Charge 4+ phone, the razer phone charges as quickly as dash.

Does a QC3 / QC2 charger charge to their spec when charging a 5T?

Nice now I'm interested in buying this phone.........

The original charger will be better, it's going to be very fast

The OnePlus 5T's charging speeds is astronomical! Check out my screenshot album for approximate charging speeds from 1% to 100%! - OnePlus 5T Dash Charging from 1% to 100% https://imgur.com/gallery/ckT4A

Hi guys,
little comparison with ugreen qck 3.0 charger. It's good, but no chance with dash charge, ~2 times slower. I can't add screenshots, but charging from 17% to 81% last 1h 15 min.

Is it just me ?
Had put my phone on charge on 51%..
After 1hr 10mins screen off it was still on 97%..
Can someone explain is this normal

idle drain about 3 to 4% always.

thats so impressiv... 0-100% in 1 hour...

Ultra fast !!

does mi 8 support mi 9 27 watt charger?

does mi 8 support mi 9 27 watt wall adapter from mi wireless charging bundle ? Then I want to know charging speed difference in mi 8 original charger vs mi 9 original charger.i was planning to mi 9 original charger for mi 9 but I saw mi 9 shiped with 18 watt charger same watt as my mi 8 adapter.so I want to know will the charging speed be the same or faster in mi 9 adapter?

almost September 2020, and I have news for you ...
I'm using google translator because I speak Spanish, sorry.
August 30, 2020, I have stable miui 12 from xiaomi.eu.
I have the charger of the xiaomi mi 9 (the one that comes with the wireless charging base) and the charging result is as follows:
using the antutu app it says the estimated capacity is 96%. In 65 minutes it has charged from 3% to 87%, it is not as fast as the xiaomi mi 9 (change my mi 9 for a mi 8 and money) but I think it is charging at more than 18 watts.
According to Antutu, the temperature of the battery is 36 degrees and that of the CPU is 39, but before these temperatures were between 45 and 50 degrees.
I wait for your comments about it.
Thank you.

Yes it does, and it should be faster compared to 18w one that came with mi 8. (27w>>18w)

Currently doing a test to compare it with the Mi 9. Have both the Mi 9 and Mi 8 and I have the 27W charger. Currently testing the Mi 8 from 55% to 100%, doing the same with the Mi 9. Will update on this.
EDIT: 27W doesnt work on the Mi 8. It took 55 minutes to get from 55% to 97%.

I have tested my Mi 8 with USB-PD 2.0 and 3.0 Chargers.
QC3 18W - charges about 1,5% per minute at 2400mAh
USB-PD 27W - charges about 2% per minute at 3200mAh
QC4 is based on USB-PD with a few super awesome secret features, if you ask Qualcomm.
What's needed is a USB-PD (or QC4) Charger that delivers 3A at 9V.
The Charger needs a USB-C Port and you need to use a USB-C to USB-C Cable without any adapters.
But don't get too happy right now. I present you the problems:
1. 27W Charging only is faster up to 60%. With a charge rate of 3200mAh at 60% the battery voltage reaches max and the phone needs to cut the charge rate down. At 70% the charge rate is down to QC3 18W at about 2400mAh.
2. I tested this in a room at 22°C. Battery temp at 24°C.
After about 10 minutes (20% charged), the Mi 8 is getting too hot with more than 34°C. The charge rate immediatly cuts down to 2700mAh. After a few minutes it cuts down to 2400mAh and we are back to 18W QC3.
I have to admit, I already tried to charge my Mi 8 with a tiny USB Fan cooling the phone while charging at 3200mAh.
Yes, that works, but.... I mean.... Cmon, I am not gonna start building me an aircooled charging station.
Btw: I am on Xiaomi.eu weekly Rom. Not sure about the official Rom, but isn't Xiaomi advertising QC4 for the Mi 8?

With 27 watt adapter , charging speed still suck like 18 watt adapter:3 but device is cooler and it's like no heating at all. That's the only difference.

Well, QC3, QC4+ and USB-PD, they all charge at 9V.
QC4+ and USB-PD are just able to charge with about 30% more amps.
The high temperatures, when charging, results mostly of the transition of the 9V the charger has to send over the USB-Cable, in order to keep the amps low enough in the cable, to a max of 4.4V the battery needs.
This causes the battery to heat up, exactly like high CPU temperatures heat up the battery. Its a small device, thats all.
What I want to say is:
You are wrong. 27W chargers do charge faster, about 30% faster.
You charged from >55% to 100%, of course there is no advantage in comparison to a 18W charger.
You are right. Charging speed still sucks at 27W chargers.
I really appreciate the 27W charging. During the day, when my mi 8 is down to 30%, I can charge it for 10 minutes to get back to 50%. Thats a lot and most of the time it's enough for the rest of the day.
Every night, I charge my mi 8 with a 5V 1A charger. No need for fast charging there.

I came here to say pretty much the same thing, you will only see the benefit if your battery is low. So charging from 20% to 60% will show some increase in charge speed, from the there the heat protection mechanism via the kernel will slow down the charge rate. Its truly not a good idea to charge your phone too fast, as heat will decay the battery much faster.
Although it's nice to have the option if you are in a hurry. My charger is next to a large fan ( works fine, stays cool)
BTW, here is a great informational article concerning prolonging the battery and avoiding heat: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

0% to 100% in 55 minutes is impressive. Although just from the numbers, with no personal experience, it's hard to believe. This would be a charge rate of at least 4000mA.
Can you do me a favour?
1. Can you try charging your Mi 9 with a QC3 18W charger and tell us how long it takes from 0% to 100%?
2. Can you try this app: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US

I hope you did not get the feeling that I was assuming that you were lying about the charge time.
Maybe you found out your charge times weren't what you first think there were and that's why you did not answer to this day.
Maybe I was wrong not believing you.
Everybody makes mistakes, it doesn't count who made them. What really counts is to make mistakes in the first place. I don't know any other way to improve.
Long story short: I want to apologize. Please come back and tell us about the charge time of the mi 9 with the mi 8 charger in comparison to the mi 9 charger. That would make this thread complete.
I am really interested if the mi 9 got any advantages in it's charging hardware. I can't find anything about it but it seems that the mi 9 really charges a bit faster than the mi 8. Looks like there are improvements made in the mi 9.

Doubt about fast charge

Hello friends. I've just bought a S20 FE Snapdragon to my wife but I have a doubt about fast charge.
My 18W Quick Charge 3.0 and my 27W Quick Charge 4.0 don't work as I wished. They just do a normal charge.
I've read that Exynos Edition uses Samsung 25W charger, but what about the Snapdragon edition? Does it use this 25W charger? What about the 45W charger?
Thank you guys.

yes it supports up to 25watt charging, you have to turn it on yourself if it's not activated.
battery and device care / battery / more battery settings / enable fast charge

Thank you for the reply. I've search it and it's enabled by default. I tried an Aukey Quick Charge 3.0 18 W and worked. It says it's fast charge. It's not stellar but way better than 2+ hours.

even without fast charging I don't wait 2 hours

I didn't try the 15w charger that comes in the box. What I think that was weird was my 27W Xiaomi charger charging with the time beyond two hours until it finishes.
Do you know if the 45W charger works?

nothing above 25watts will work any faster, the maximum current draw is 25watts if it works at all. not all fast chargers do work properly, that might explain your Xiaomi 2hrs plus.
the phone and the charger need to be able to communicate with each other / be running on the same standard.

Yes man. That's even sad because they put a beast like a Snapdragon 865 on it.

I am satisfied with original 15W charger: 11%~100% in 1h20m is decent speed and at the same time low stress for battery.

True. I just bought a Samsung 25W super fast charge to my Snapdragon 865 and worked. I'll buy one for my father that uses an Exynos SoC too. It's sad to spend money with something like that.

I use the Samsung 20 w brick. When fast charging it get about 2%@minute.
Fast charging will not engage if the start temperature is too low or high.
If the battery has failed*.
Fast charging ramps down at around 80% to slow charging or if battery temperature goes to high. If temperature continues to climb above 102 F or so it will disengage entirely and end that charge cycle.
After 90% the charge rate crawls at as little as 1%@2 minutes.
* check for rear cover bulging. A battery can fail at any time but it's more likely to happen in an older degraded cell. Failures can happen fast, replaced asap, like that same day, if this happens. It can destroy the phone.

Question Best charger/wattage for best battery life span

Hello people I recently acquired my 11t pro and I know that the 120w charging, first it's amazing, but second it's kind of concerning to think that such a charging speed might not wear down the battery life even though Xiaomi claims 800 cycles and a bunch of certifications.
So I've decided to only use 120w on hasty situations or while traveling, etc. And I happen to have different xiaomi chargers.
The question is which do you think is the best wattage or charger to make battery life span longer 22.5w or 33w?
(wish I had the 67w from the 11t, but unfortunately I don't)

You're correct. Fast charging is poison for battery lifespan, of course the device makers love that because $. As low and slow as possible is the way to go, 18-25 W as a good trade off I would say. Some, including myself go even lower.

yeah,I haven't tested the 11t pro but with a redmi note 9 using a samsung note 9 charger it looked like the redmi wasn't getting any charge up. So that low is good?

i use 12/15w and its perfect !

Im charging mine with standard 5v 2A (its slow, but i thing battery will have better life down the line) since im planning to use my phone for 4-5 years minimum (last phone oneplus 2 was in use 6 years)

How long does it take you to fully charge? Or what charging strategies do you use?

Both options are good ideas for overnight charging. Will keep that in mind using a Samsung charger

Yes, you are right, when you are not in hurry i dont see reason not to use slower speed charging and then if you need speed use fast charger once in awhile

Well just as an addition I've tested several chargers with different wattages and these are the results in terms of time:
Samsung 10w - 2h:40min ±
Xiaomi 18w - 1h 30min ±
Xiaomi 22.5w - 1h 05min ±
Xiaomi 33w - 50 min ±
Xiaomi 120w 17 min at least for me.
Charging from around 10 to 100%

I am using Samsung 15W charger, around 2h to fully charge the phone.

I use a 33W charger from my K30 Pro Zoom. I charge from 20% remaining to 90% in 30 mins. Probably 45 mins if totally drained but never have to wait for an hour to fully charge. I only use 120W during business trips or Out of town.
By the way, your cord needs to match the type of Charger you are using or you'll just end up with a bottle neck charging.

I think the best option would be 65W, either mi charger or anker. Im currently using anker 65w charger, and oh my god, im getting a beautiful battery life of upto 8 hours sot on heavy usage. And by heavy usage i mean, streaming, maps.
With heavy games as well, its a bit lower. But charging with 120W affects the battery negatively. And i think it doesnt charge it completely even though it shows 100%.
