Best US Note Charger, Fixed Issues, and Cheap Too!

Just wanted to tell my fellow US Note users that I found what I deem to be a great deal for a fantastic US charger.
I didn't have a converter to use the supplied European charger, so I used my old Motorola Droid X wall wart and USB cable. It worked fine, but I noticed that it made my touch screen a little less sensitive. For instance, it might make my Swypes on the keyboard break into separate lines, confusing Swype. It charged my phone, but the battery got warm; I thought all of this was normal. I tried another charger, an LG one, just to see if that changed anything, but it worked about the same.
Then from reading around, I realized that the standard charger is a 5v 1.0A charger and both chargers I was using were 5.1v 750mA/850mA chargers. I immediately started searching for a direct replacement and only after a long search I found a Palm Pre charger with the exact specs as our Note's.

I assumed it would charge faster being a 1A charger, and it does, but what I didn't expect is what pleases me the most: the screen sensitivity when charging is immensely improved (Swype is exactly like without the charger in) and the battery stays dead cool! It is around 5c cooler according to SetCPU. Just awesome!
I'm so pleased I wanted to share. I hope this helps others who may have experienced similar issues.
The link is below (not sure if I can link directly to an Amazon item, hope this isn't against the rules.) It's super cheap and the quality is top notch! Soft touch plastic on the wall wart and also the USB cable! I just bought another as a backup. It's only 3.49 w/ free shipping!
BTW I bought it from "BobTronics" because some reviews said they got what might not be genuine Palm USB cables from other sellers. Mine is legit; it has the palm cable tie and feels high quality.

P.S. I am in no way affiliated w/ the item or the seller. Just wanted to share a good buy that others might be interested in.

As a Palm Pilot -> Tungsten -> Palm Pre ->-->Pre 2 user I have to agree.
I have numerous chargers, some even labelled at 1.0 AMP, but none as good as the Palm charger. Just well built, FULL 1.0 Amp, and so pocket able.
Now if only I could put my Note on my Touchstone - I find the Samsung Dock and connector sooooo clumsy after the Touchstone.

I have to agree, and the picture did not do it justice, because this thing is very compact. The diameter appears just larger than a quarter. I'm pleasantly surprised-for a change.

The DELL Streak's charger works superb, I have 3 which I have tried, for super fast charging use the ipad charger its rated at 2 AMPs.

I wonder if that causes any unnecessary stress/strain on the battery or the phone itself. I was worried about the heat that came off of my phone w/ the Droid & LG chargers, probably more due to the 5.1v rather than the amperage though.

I have the same chargers that came with my HP Touchpad during the fire sale. They are excellent chargers and I also use them on my non HP mobile devices as well.

Note's circuit limits the charge current at 1 amp.
2 amp Improvement is imaginary/placebo as charge times are exactly similar to 1 amp.
I have a Galaxy Tab charger rated at 2amps and it takes exa tly the same time to do a full charge as with the bundled charger at 1 amp.
Hence, no need to worry about temperatures.

In that case, I am even happier w/ my 1A charger.

Car charging whilst on GPS

I have used my new Nexus4 on the road with google navigation. I was surprised to find out that the 1Amp samsung charger I have used with my SGS2 was not able to maintain the charge of the phone. After couple of hours of driving my Nexus 4 died ( I didn't start with full battery)
What is your experience? I would expect the phone not only to work whilst on cable for the whole time, but also to eventually charge the phone fully.
Now I am not sure if it is my charger or nexus 4.
I had a look on mains charger and the output is 1.2Amp, is this the problem, that the car charger is not powerful enough?

I currently use CAD300UBE, which is the official i9300 car charger, with a rated output of 700mA.
When streaming over bluetooth using Spotify, and using Google Navigation I can say that this charger does charge the phone.
My old S2 charger, also genuine did not manage to charge my S3, hence the replacement.
Phil

My recollection is that Nexus devices are looking for pins 2 and 3 (data) of the charger to be shorted. If they are not, you'll only get 500ma from the supply.

Turn the screen of when not needed in navigation,

I use a kensington 2A flush cigarette lighter so it isn't an issue, the charger is <$15, and it makes life easier when I want to charge my ipad. Only thing I regret about the charger is that I didn't get the dual port version.

I posted this in the GN forum about a year ago when the same sort of problems were coming up there. You need a 2A charger and a data only cable to make you charge like you are on a wall charger. (Charging AC - Check this by going to Settings > Battery, the top shows charging AC.

There was another thread, I think in the General that discussed all of this, what people came up with was the best combination if you want a dual port usb charger is to make sure you have a "charging only" USB cable. This cable will not make your phone think it is connected to a computer. You can tweek a data/charging cable to work but some people messed that up so it is probably worth just spending the $4 on a cable that works.
Here is my combination that works great. With this set up I can have on my navigation going with the screen on the whole time and stream Pandora over Bluetooth into my car and the battery still charges really quickly.
Dual USB Port with a 1 amp port and a 2.1 amp port (2.1 amp port is for tablets or power hungry devices - like the phone while navigating). http://www.amazon.com/gp/product/B0056VNVV8/ref=oh_o01_s00_i01_details
Charging Only USB cable:
http://www.amazon.com/gp/product/B003VYBCAY/ref=oh_o00_s00_i00_details
This combo has me as "Charging AC" whenever I am in the car and I still have a port open to charge another one of the 27 or so different electronic devices that seem to clutter my life!

Here is what it should look like in the car if it is getting enough juice to run everything at once.

I just checked my charger and it does say 700mA and also shows charging as AC. But in reality the charger was not able to charge the phone whilst on navigation.

Mine too, but I actually installed a dedicated 2 amp, isolated supply in my truck, shorted pins 2 and 3 on the USB connections on the board with a couple of beads of solder, and get full charging current on both my Nexus 4 and 7.
This is the supply I used:

My Nexus 6p charging slowly according to the ampere app,its showing less current.help

Please help
Want to knw is it the app defect or my phn defect?
With my stock nexus 6p charger it showed me max current of 1500mah whats wrng?
The day i bought the device it showed me 2950mah.

A couple questions regarding your issue:
Is this the charger that came with the phone, USB Type-C on both ends?
What was your battery percentage when this measurement was taken?
What were you doing on the phone at the time of the measurement?
I assume from your post that question one is a yes. I ask question two because as your battery gets close to full (and in the case of most lithium battery charging) the amperage will lower to finish topping it off. Question three is important because I believe the Ampere app shows the net total amperage flow. Meaning that (a mA in) - (b mA being used) = (c mA total flow). So if you have brightness to max, music playing, etc. then the total mA flow will be lower.

Yeah am using the same charger usb c to usb
And i checked it on all percentages it ws same it never exceeded 1500 and sometimes it showed me 600 also
I was not doing anything at that time
Just charging my phone what should i do now?

Hmm... I've gotten weird readings from Ampere sometimes. Give the Current Monitor app a try perhaps.

same issue and haven't found any solutions so far

Could be the charger being defective, hard to say. Or the USB C port. Check if there is lint build up in the port.

It's ****ing weird. Never had these sort of issues using the QuickCharge 2.0/3.0 and micro-B connectors.
I cleaned out the port with isopropyl alcohol and compressed air. I've got some 3rd party chargers that register as "charging rapidly" but have yet to see current even close to 3A. Using the same cables, the OEM charger is still stuck on just "charging".
I can't seem to really push past 1.3A regardless of battery state, charger used, or cable.

By comparison, this is what it looks like with 3A charging. The bulk charge rate is near 80% per hour.

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 Samsung Galaxy A7 (2018) can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

From 8% to 100% mine takes an hour more or less

Now this is interesting.
I am using usb power meter alongside the supplied charger and cable in the box and I found that even after the phone showed 100% charge it continued to draw current (~300mAh) for another 20 minutes until stopped entirely.
So my total charge time from 0-100% was 2 hours and 44 minutes.
Also for the first ~60% charge the phone draw the full 1.55 amperes and after that gradually dropped down to 0.50 amperes.
While the charger runs little bit hot the phone was cold the entire time.

2 hours to charge from 15% to 42 %
too long

This is way too much. You have probably got defective charger/cable.
But! If you are trying to charge it from a pc then is normal as regular usb ports supply only 0.5A instead of the 1.55A from the original charger.

I just realize charger is defective
Should i fix it or buy new one
Idk if its the cable or adapter

Nowadays chargers are basic inverters with few more stuff.
They have very few components inside but sometimes, usually after hard hitting/dropping on hard surfaces the soldering can get damaged with varying consequence between simply stopping working to working abnormally as lowering voltage, current, overloading and many other things.
For example I had a strange case with fully working charger with healthy components and solder joints but was working on random intervals. It was caused by solder whiskers touching nearby naked track and causing shorts. If it was cheaper charger it would blow, but in this one the overvolt protection was able to save it.
And this is why you can just buy usb power tester like this one

or even simpler like this one
so that you can check what kind of power your phone actually receive from charger/power bank/pc etc.
Our phone does not have fast charge. As such it will not charge faster no matter how powerful charger and cable you can equip it with. For example I have one with 2x2.4 Amperes supporting QC charger mods and etc. - it will draw only up to 1.55 Amperes within 5 Volts range.
The normal USB 2.0 port can supply with max 0.5 Amperes, USB 3.0 within the basic implementation can supply under 1 Ampere.
In simple language this means with usb 2 it would take up to 8 hours to charge from 0 to 100%, with usb 3 it would take about 4 hours and half from 0 to 100% battery.
Of course depending on the manufacturers you can find usb 3 and 3.1 ports that are able to supply way more current, even values like 3 Amperes and higher.
This is why the best way to charge your phone is to use the supplied charger. The cable is also very important because of the current depending on the used wire gauge.
With cheap cable (using thin wires) you would not only be unable to use the available current, you can find yourself in the middle of fire.
But there is a big problem, the price sometimes doesn`t represent the needed quality.
Notice I`m not talking about durability. I can show you cables strong enough to endure 10 kilograms but with so thin wires that can`t carry over 0,5A trough them.
Put your trust only on products that are widely commented and tested by the buyers.
Now, I have tested the cable supplied with the phone. Although it easily handles the 1.55A current used by the phone if you put over 2A it will get really, really warm. This means the wires are big enough but are not expected to handle high current. In simple words don`t use this cable for other things than charging this phone, just to be safe.
=====================================
TLDR;
If you don`t have the necessary skills don`t try to repair it. Any repair error can easily make it burst in flames. Better try with another charger but make sure it can get you at least 1.5A otherwise it would take really long time to charge.

Is there a fast charger available for this phone??

yes, I recommend oppo charger. In just 2hrs the batt will be full.

Is there a way to charge faster? In my case I can charge my phone maximally at 5.19V / 1.42A. Charging from 0% to 100% phone with such parameters takes more than 3 hours, because amperage is adaptive.

it took less than an hour for me from something below 30% to 99%.
edit: i can provide a gsam battery image if you like to.

I know..but his is how it is..

Note 8 pro does supports 18W fast charger. The charging speed is pretty good for me.

https://www.xda-developers.com/redmi-note-8-pro-teardown-confirms-quick-charge-3-0-support/

I did a test with my device. So at 4% battery, I put it in airplane mode. I used a 30W charger, with a USB Tip C - USB Tip C ports. It took 107 minutes to fully charge. Until 80%, the charging speed was about 13% per 10 minutes. After reaching 80%, the charging speed decreased. The phone reached 81% in 60 minutes. I logged the battery percentage and charging speed percentage every 10 minutes, and I included in a excel graphic. I attach this file. Maybe someone more tech savvy can understand more about the inner mechanism and if it is QC 3.0, 4.0 or whatever.

good

I have a QC4+ charger and a usb power monitor and it only shows QC3.0 on it`s display as the charging method on my 8pro.

I found it funny that using an old 10w charger takes about 15 minutes more to charge my device.
I keep using the old one as it produces less heat, and theoretically should prolong battery life.

Average charging speed with the fast charger provided with it, is 1 point rise per minute.

Which app is preferred to measure the current speed specially in Watts?
