i have lg pro 2 charger and it charge my tab s faster than the samsung charger
why is that?
check the V. My Note 2 charger charges slower because its 5.0 V, but the tab S is 5.3 V. Lg charger might be more.

yea you are wright so is it bad to use the lg charger?
lg v is 5 only can this damage the battary?
What you really need to compare is the current output (Amperage) output of the two. 5V or 5.3 will surely be OK. I think the Samsung wall wart is 2.1A your LG wall wart is most likely higher than that and this is really why it charges faster. It might not be good for the battery if it's too high. I don't know what the limit would be....
thank you pro
Your samsung charger is broke if the lg is Truely 2 times faster.
no not broke i tried 2 samsung charger and the same
lg charger was charging the lg pro 2 from 5% to 100% in one hour maximum
Please post the model number of LG charger.
lg travel adapter MCS-Q4UR
Bre careful i recomend u dont use another charger for ur device
How long take you charge from 0 to 100%?
Voltage is not responsible for charging time, but current. Samsung genuine charger has 2.1A current, but galaxy tab S gets only about 1770 mA (1,77A) maximum current (I measure this using voltage/current multimeter).
I have many chargers, and any of them (despite some of them have over 2A current) gets maximum current to galaxy tab S about 1.77A.
I also have I9300, and custom kernel (Boeffla, you can select own charging current from 0 to 1600mA), but i9300 takes maximum 920 mA (I don't know why they develop thi function to set current over 0.9A). Setting current over 920mA nothing changes.
I have to add, that very important is USB cable. Device can test the maximum current of charger, and when cable is not ok (for example cable is very thick) device can use a smaller than charger maximum current. You have to notice, that cable can works OK (transfer and/or charging) but can charge smaller than maximum current. Unfortunately on non-rooted devices you cannot see charging current (on device, of course you can use external multimeter)
I have many USB cables, and some of them on original samsung charger uses about 0.5A what is about 3x smaller current.

Please do some research if you have any concerns about using fast charging.
I managed to get my Nexus 5 charging at 1850mAh on Quick Charge 3.0 charger!
In theory, Nexus 5 can support Quick Charge 2.0, because it uses the Snapdragon 800 chipset,
but it uses a Texas Instruments BQ24192 chip for battery charging and power path management,
which does not work with Qualcomm Quick Charge. According to AnandTech ( Google Nexus 5 Reviewhttp://www.anandtech.com/show/7517/g...exus-5-review/3 ),
the Nexus 5 should automatically restrict charging rates to a maximum of 1500mA.
Quick Charge - fast charging technology
Qualcomm Quick Charge 1.0 is able to charge up to 40% faster than conventional charging (Max Power 10W)
Quick Charge 2.0, increasing the charge time advantage up to 75% (Max Power 18W)
Quick Charge 3.0 is designed to charge twice as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick Charge 2.0 (Max Power 18W)

LG Nexus 5 D821 32GB ([email protected],65GHz)
Stock ROM 6.0.1 MMB29M + ElementalX 6.07 Kernel (Fast Charge Enable)
Anker PowerPort+ 1 with Quick Charge 3.0
RAVPower Portable Charger 20100mAh with Quick Charge 2.0
Anker Premium Micro USB Cables in Assorted Lengths (3ft, 6ft, 1ft)
PortaPow V2 USB Power Monitor + Ampere App
Original LG Nexus 5 charger and USB cable

Please note that I bought my Nexus 5 in November 2013 but I replaced the battery with a new one.
The maximum charging rates was 1850mAh - reading from PortaPow V2 (1530mAh - reading from Ampere app).
Tests
1. Nexus 5 Full Charge Time = 1h 20min 43sec
2. Nexus 5 Charge Time - 5% step (minutes)
3. Nexus 5 Charge Level - every 5 minutes (%)
4. Battery Charging Time Comparison (3A Charger)
I'm going to do some more tests soon.
5. Anker Quick Charge 3.0 charge + USB Cables (Nexus 5, OnePlus One, Anker, RAVPower ) vs Amps
6. Best cable from Test 4 + Chargers (Anker Quick Charge 3.0 charger, RAVPower Quick Charge 2.0/2.4A power bank, OnePlus One charger, Nexus 5 charger) vs Amps
7. RAVPower power bank USB Type-C (3A) output - I need to buy a USB-C to Micro-USB cable
Conclusion
The Nexus 5 was released more than 2 years ago (October 2013) and we can use it for everything!
We can overclock it, shot 4K videos, play H265 movies, create VR headset for PC gaming, run Window 7 or boot Windows 10.
Now you can fast-charge the battery. The Nexus 5 is a Quick Charge 1.0 device, but provides the same charging speed
as the Samsung Galaxy S6 that supports Adaptive fast charging or Quick Charge 2.0.
The Nexus 5 is a simply unblieveable phone!
Whoa, that's great news, mine tops 1500mAh with simple Asus 2A charger. It's not consistent though. Sometimes works, sometimes tops 1A. Couldn't figure out what stands behind that.
Says "fast charging" on home screen as well. Using Cataclysm + EX Kernel. Here's some more info on reddit.
https://www.reddit.com/r/Nexus5/comments/3y6u7l/nexus_5_fast_charging/
The max. charging current was 1850mAh!
I know Uber kernel has a setting to choose max charge current, and it goes up to 1900mA. Tried it a few days ago but as i dirty flashed kernel, my phone was buggy as f*ck and i returned to ElementalX lol
I guess it is awesome.
But can it be harmful to the power controller chip...?

Must be the same current - 1850mA (EX) is almost 1900mA (Uber), I don't think you can get more.
Two years ago we charged the Nexus 5 for 2h 32min, now we can do it in 1h 20min - increasing the charge time 47% faster!

Yay, this will really ruin battery cycle life.
This is on stock 6.0.1 locked bootloader, no root. I plugged it into my Moto X turbo charger that has 3 different charge levels.

You just proved that it doesn't, with a qc 3.0 charger it only charged at 10 watts(volts*amps), that qc 1.0 spec.
If it would support qc 2.0 it would switch to 9v and even 12v during charging but it doesn't.
The reason anandtech showed 2.5 hours to charge is because they use oem chargers to charge the phones, think it was rated at around 1 amp. Switch to a high quality 2 amp one and it fixes the problem, my blackberry 1.8a charger does the job as quickly as your qc 3.0 charger.

It's true - the Nexus 5 is a QC 1.0 device, but it provides the same charging speed as the Galaxy S6 that supports Adaptive fast charging or Quick Charge 2.0 (see Test 4).
Ok, the battery capacity is lower 2550mAh vs 2300mAh, but the charging time is still really impressive for a 2 years old smartophone.
BTW, OnePlus One supports QC 2.0 (can switch over 5V - tested!)

Using a $3 blackberry folding blade charger I get 1800mah charge rates. No quick charge charger needed.
Just something to consider, a regular Nexus 5 is charged at about 900mA up to 1A current ( measured from my DIY power supply ). If you double the current, you also increase the power dissipation of the charging circuit by 4x. Sooner or later the whole device will fail.

No one here is forcing 2 amps into the phone with some hack, its pulling it by itself, meaning its capable of pulling that much current.

You can use QuickCharge 3.0 charger but the Snapdragon 810 supports up to QuickCharge 2.0.
https://www.qualcomm.com/products/snapdragon/processors/810
So, you will be limited to 2.0 "speed".
i used SONY CP-AD2 charger rated at 2.1A. it charged at 1.31A according to ampere app. but it fully charged from 4% to 100% in 58 minutes. the best charging time i have ever got.

Hi.
I originally came from a vibe P1 which is now my gf's. One issue I had with the P1 is it gets noticeably hot during charging, which I take is not so good for the battery. Can I use a lower rated charger and let the P2 charge at normal speed to prolong the lifetime of this phone? I currently have a 2A charger from a Xiaomi RN4, I do not know how much current is the P2 charger rated. I'd appreciate all inputs.
Thanks.
you can indeed . of course it will take a bit longer to charge the phone . I use an old Samsung charger - 0.5A for charging phone and tablet .

Any chance that you know the Watt rate of the stock charger that comes with the phone? I have a 5V 2A charger which I guess is 10W. I have no idea how much W is Quick Charge 3.0 rated for but I'd like to have one quick charger to bring with me on trips and a normal one to charge it at home in normal situations.

I received the phone today. I think the charger that comes with the phone is some kind of quick charger because it is rated for different voltages, about the same current. So the verdict is the p2 has quick charging, just not Qualcomm's quick charge 3.0?

Exactly.
It is really strange, but so it is.
I want to optimize the charger's time speed by buying a new and trustful charger, but I don't have a clue about how many watts this Quick Charger 4.0+ on the redmi note 8 pro supports... someone may give me a little help? ?
Looks like even though the processor supports qc4.0, Xiaomi went with a qc3.0 Battery Charger chipset.
https://www.xda-developers.com/redmi-note-8-pro-teardown-confirms-quick-charge-3-0-support/
what!?! so it isn't QC 4+ ??
guess gotta see what's its maximum watts support for QC 3.0 then ;---;
