Hi
Pls tell How to use Ampere apk?
I recently installed Ampere apk. I tried but most of the 1-2 amp charger at home, my 2 amp chargers are showing reading of 1800+ but after a few minutes they come below 700 or so.
Am I doing something wrong or Pls tell how to use this apk properly ?
regards
What version of android are you using?
Hi,
What all Ampere do is to measure charging current. With some adjustments, you could also measure discharging current...

As quoted in the OP of the app thread:
"Background info:?*The app measures the battery charging/discharging current. If your phone is not connected to a charger, you see the discharging current which is negative. Now, if you connect a charger then the current what the charger gives will be used to supply your phone and the remaining power will be charged into the battery.
If your phone consumes 300 mA without a charger connected, then a 500 mA charger will charge your battery maximum with 200 mA current."
https://forum.xda-developers.com/android/apps-games/app-ampere-charging-meter-t3012890
With that in mind, your charger probably have an initial output of 1800+ mA but since you're charging your phone with the power on (or most probably using it), the charging current drops to 700+ mA because the charger must also sustain the power that the device is using.
Another probable reason is your charging cable. Do you try using other usb cables? Ampere is developed for us to detemine the best charger+cable combos for our device.

Does that mean charging will be more effective when charged by 2 Amp non-usb charger?

What do you mean by non-USB charger?
You just have to try other USB cables and look for the one that gives the highest charging current to your device.

I've been hearing a lot about these 2 amp chargers charging devices really really fast. I heard them talking about it on the podcast also but I was wondering if they were safe to use with this device? If so I'm gonna purchase a few. I don't want to damage my new battery so that's why I'm posting this. Thanks.

I charge my N3 with the original charger (2A/5v) and bought a 2 meter usb cable, its 100% fullly charged in about 1-1,5 hrs i guess.
I have A 4Ah charger but with 4 ports can go as high as 2amps on a single port.
Usually it charges at 1amp.
Intelligent charger so ramps down charge when needed

I'm charging my note 3 using this charger which have 2 ports, one 2.0A and the other 1.0A. From 0 to 100% in about 2-3 hours.

It looks pretty good!!!!!! but I charge my Note3 with the original charger (2A/5v). Thanks for your post.
The original stock charger 5.3V 2.0A is the fastest, it was made for the note 3, even a 5V 2.0A will be slightly slower.
Do also note that the cable plays an important part in the charging time especially in my case where I'm using a third party cable and charger.
Using the following app, it can show how much current it's currently charging. Here mine, post yours if higher then mine. Can someone post the screenshot using the original samsung usb cable and charger as a reference too?

Just got my Note 3. It charges at 1800mAh on the stock charger (see pic).
It's weird though, because my Galaxy S4 charges at 1900mAh on its stock charger. I assumed that with USB 3.0, the Note 3 would somehow charge at a faster rate.

Thanks for the info. I tried charging with a third party USB3.0 cable and a third party charger and it did reaches to 1800mAh.
Using USB3.0 and USB2.0 cable does make a-bit of difference.
The upcoming Oppo Find 7 have this 4.5A charger that provide a technology call VOOC charging.

USB 3.0 makes a difference only to data transfer and not charging the battery when compared to USB 2.

You are right. USB 3.0, the latest version of USB (Universal Serial Bus), provides better speed and more efficient power management than USB 2.0. USB 3.0 is backward compatible with USB 2.0 devices; however, data transfer speeds are limited to USB 2.0 levels when these devices inter-operate.
Just wondered, is there anyone using one of those 3A chargers to charge their device?
Since Z2 supports upto 3A charging.

I think this is manufacturer and kernel specific.
How quickly would they charge with 3A...
I use 1A through magnetic and it's lightening quick

3A would be twice as fast as the stock wall charger and if yours is 1A, it'll be thrice as fast.

Li-ion batteries are smart, so are the chargers. If possible check reviews about whichever 3A charger you pick first. Battery won't get damaged because the chip they use will prevent charges heavier than they accept. Its all about if anyone's willing to spend the extra money to perform this experiment and see if the charger will actually make a real world difference in charge time or not.
those things are just huge!

I'm thinking about buying one... would be nice in some situations to charge with full 3A but i still think it's bad for battery longetivity.

It's actually not that easy, usually a battery charges to 80% in half the charging time and to 80% out of that 80 in a quarter of the charge time. Guess what I'm trying to say is that charging is not linear, meaning the equation is more complicated

I have a few of these http://www.ianker.com/product/71AN7105-W5A
Says it can output 8A per port. Do you know how to see what current the phone is pulling?
Honestly I have my set via the kernel to only charge at 1200ma max

Why'd you limit it? Secondly the only way to find out is noticing the charge time I think.

Faster you charge lithium batteries, you reduce the number of charge cycles. I'd rather charge it slower, especially because you can't change the battery.

True,
I have multiple chargers, in the car I have 1.2A (Sony original car charger), in work I have 2.0A ( Samsung original charger )... but near the bed I have 0.35A (Sony bluetooth headphone charger)... while sleeping I don't need fast charging so I went for the lowest possible power...
please dont try high amperage chargers... might burn the chip!
Can recommend any microUSB cable (not USB3.0) to fast charge my Note 3?
I'm using a original Nokia CA-101 microUSB cable and it charges between 1200mAh to 1800mAh. It only 12cm in length so I'm looking for a longer one, say about 1m.

Same reason transfer rates are increased on a 3.0 cable vs 2.0 (standard) the cable has more metal at the connections literally doubling the capacity the cable can put out.

Whoops I should have proof read what I wrote. 3.0 cable has faster transfer rate and can double charging speed and data speed and the 2.0 cannot have the faster speeds because it is smaller.
I'll edit my previous post.

You don't need a 3.0 cable to do a fast charge. Multiple people on this forum recommend this cable - I purchased two myself and can confirm that they charge at 1800mAh. Keep in mind that the Note 3 charges faster with the screen off than on (1200mAh vs 1800mAh).

I got the same icons as you..
It's charging according to ampere (app) max at 3130mA but usually it's on 2750mA
Same with mine (ordered from aliexpress) look like the first photo with different serial number and same weight and feel as the original but it stop dash charging at 81-84% and do nothing after that.
I think the normal dash charge is up to 80% and the remaining is done at regular charge.
It look like this charger can just do dash but not lower amp charge. I try it with my samsung tablet and it's don't supply enough pover to charge it. Maybe it's missing some chip inside or it's a batch of deffective chargers rejected by onplus and sell under the table.
I'm in the UK but this is my charger, bought from one plus 1 minute after the phone went on sale.

It's normal behavior. Dash drops to 2A after 75% and even lower after 85%.

the one I'm using is an original Mac book pro one which is around $70 but you can find the generic ones on Amazon for $38 I'm going to buy an extra one for my office. It is an 87 watt charger but it charges the phone a lot faster than the original Huawei one.
Just tried my handset on a couple of USB-PD chargers and getting 16W consistently.
i tried with mac pro original charger, i am getting around 3k miliAmp/hr on mac charger and 4-4.5k on huawei charger. Are you getting more than 3k on mac charger ?
MateBook X Pro Charger seems to result in something like 16W charging(just my estimate)

What's the max mA it charges at?
The stock 20x charger charges at over 4000mA when I plug it in with 50% battery.
Does it do better than that?

They won't necessarily damage the battery but will reduce it's lifespan. I generally use a Samsung charger, Qualcomm quick charge 2.0 , I also use do my best to use the 40 to 80% rule when charging.
