Re: Check if your device is charging correctly

Installed the app from OP. Is there any settings? I've disabled the menu button, and didn't get the onscreen menu. I got it in the lite app from Play Store.

Was wondering if black theme is available in the apk in OP.

I tought CM 10.1 was the issue, but after reading this thread, I'm starting to think it is the stock charger/USB-cable.
[Android Software Development] abmantis:
Only the Pro version has the dark theme, sorry.

Most users find that using another cable / charger is the solution, and that the problem is not ROM related.
[Android Software Development] Focus909:
I have to agree. I installed a flat cable in the car and would not charge properly at al. When I went back to the original cable it worked fine.

Anyone used Nokia AC 10e charger with S3? It has 1200mA, 5V and microUSB port. Battery should charge slightly faster w/o no-charge bug?

I think I will try it tomorrow :)
[Android Software Development] abmantis:
Looks like I need to go to a Samsung repair center :P

Did you have to leave the S3 with them or just the charger?

I've tried with a 2A (2000mA) charger and it charges most of the times at 1000mA, contrary to the stock charger.

By the way, unless you use a custom kernel, the stock kernel limits the current to 1A, so even with a 2A charger, it just takes 1A max.

Re: Check if your device is charging correctly

Not sure if this is the right place but here I go.

Is it possible (maby through kernel tweaks?) to make the device think that its charging from a dcp and draw the whole 1.2A from usb ports that support current draw of at least that (~1.5A).

As far as im aware the phone checks for continuity of the data pins. The device can tell if its a data usb port or a wall charger ect..

So im thinking it may be possible to trick the device into thinking its able to draw more somehow through software???

Does anybody know if this is possible?
[Android Software Development] reissejx:
that means, its not rom related.

change your charger. :)

---------- Post added at 10:22 AM ---------- Previous post was at 10:17 AM ----------

try ExTweaks, you can change the maximum mA you can get using USB and wall charger.

but it should be supported by your kernel.

im using berrzebb and i was able to draw 1A from USB.

Re: Check if your device is charging correctly

Test Results:

Using an ATT Samsung Note 2 with:

1) the original Samsung charger and a 10 foot/3m cable from QVS:

Maximum: 400 mA

Now: 1698 mA 4.003v

Avg: 400 mA

With original (short) white cable:

Maximum: 1300/1500 mA

Now: 1698 mA 4.131v

Avg: 1300/1500 mA

2) Avantree 2100mA Dual Standard charger

(Samsung socket) and the original (Samsung) short white cable:

Maximum: 1000/1100 mA

Now: 1698 mA 4.096v

Avg: 1000/1100 mA

Maximum & Avg seems to change depending on how discharged the battery is.

(Apple socket) and the original (Samsung) short white cable:

Maximum: 460 mA

Now: 466 mA 3.995v

Avg: 460 mA

(Samsung socket) and the 10 foot/3m cable from QVS:

Maximum: 100/200 mA

Now: 1698 mA 3.925v

Avg: 100/200 mA

(Apple socket) and the 10 foot/3m cable from QVS:

Maximum: 260/360 mA

Now: 460 mA 3.982v

Avg: 260/360 mA

I am not saying that I understand all of the results, but I do find them interesting.

Voltage is from Current Widget App. The mA from this app was always the same as the Now: reading

[Android Software Development] iSiDoRoS:
Thanks for your post. It made me understand clearly the charging problems that i had already realized with my i9300.

My stock charger and cable charges always at 1000mA. From my pc's usb port i receive 460mA. Also an HTC cable that i have charges the same.

The problems that i had were with many cheap chinese cables that i bought from Ebay. I have one at the car, one at my girlfriends house and one at work and they were all charging really really slow. When i was using the phone while charging, i was consuming more current than what was coming from the charger and eventually the phone was shutting down. With older telephones i didn't have noticeable differences. The S3 seems to be really picky with the charging current.
[Android Software Development] mar10o:
i9300 is not charging on Nokia AC-10e charger at all. No problem with my 2nd phone SE Neo V.. ?

I can't understand this.. it's really good quality charger with thick, long power cord (I'm able to use my phone when connected).

I have Nokia CA-101 data cable too, and it's charging the device (current 460mA from USB) with file transfer.
[Android Software Development] abmantis:
Yeah, the SGS3 is really picky about the cable. Previous phones would charge just fine with any USB cable!

I have used an Avantree 2.1A charger and found that it charges the device much better than the stock 1A charger.

The phone won't charge at 2A, since it only draws up to 1A. The thing is, contrary to what happens with the stock charger, with this 2.1A charger it charges almost always at 1A (1000 in current max). With the stock charger is rare to go over 800mA, and sometimes it can go as low as 400mA.

So, if you have a 2A charger (maybe from a tablet?) give it a try and check the values ;)
[Android Software Development] RDI:
Re: Check if your device is charging correctly

This Avantree Charger is Dual Standard, make sure that you are using the Samsung port so your phone goes into fast charge mode. If you plug it into the Apple socket it will charge at 500mA, just like a UPS port on a PC. (yes, we distribute this charger).

Note that it will charge iPad at their full rate when plugged into the Apple port.

Yes is the dual charger.

I've tested in both the Apple and Samsung port and haven't seen any differences on my S3.

Tried it out on my s3 LTE and note 2 LTE

1. S3 LTE results with s3 LTE charger (1.0A = 1000mA) with 5 pinouts micro USB cable

- current max -->1000

- current now --> 999

- current avg --> 1000

Conclusion: result is good

2. Note 2 results with note 2 charger (2.0A = 2000mA) with 4 pinouts micro USB cable

- current max -->1700

I am only able to achieve 1700 and not exactly the same value of the charger output (2000). Is it normal??

- current now --> 1698

It seems like it has a different current now value for note 2. Well, this value is not crucial

- current avg --> 1700

No concern as it is similar to current max

Conclusion: I have swapped 5 pinouts micro USB cable to my note 2 charger and the current max achieved was 1800. It was 100mA more than as compared with the 4 pinouts micro USB cable used initially. Do you have the actual current max reading for Note 2?

Something to add on - I believe the no. of pinouts made the difference as the cable provided with my phone package was initially 4 pins. My gf's s3 NON-LTE came with the 5 pinouts micro USB cable and we tried swapping cables. True enough, my 4 pins cable with her s3 charger took 8 hours to complete a 10% - 100% battery cycle. I went to Samsung and requested for a 5 pinouts cable warranty exchange, it served me well for the last 2 months.

My charging benchmark for my s3 on AC condition --> 1hr = ~ 45% (current max = 1000)

Hopefully this info helps.

Cheers

abmantis:

Thanks for this app. I am really happy with the information I got from it. I have done some extensive testing on my Samsung Galaxy Note 2 i317 and here are my results:

"Current_now" is binary: 1698 (AC) or 899 (USB) charging

"Current_avg" is accepted charge: It range between 400 - 1800 for the Note 2

"Current_max" is attempting to charge: again range from 400-1800.

At first plug in, current_max fluctuates in order for the phone to determine what is the max charge the phone can draw from charger and cable combinations. Current_max settles after about 15 seconds. Then the phone stop attempting to take a higher charge than current_avg.

Current_avg is actual charge the phone is accepting. On a bad cable (thin cable and or bad connector), when I wiggle the USB connection, current_avg and current_max will fluctuates.

In my testings, my phone correctly recognize AC and USB laptop charging.

What I find is the cable is often more important than the charger itself. I have 8 USB chargers in total, all actually performs better than their rated current, maybe that is their minimum current rating, e.g. 1Amp can do 1.2Amp for example. You can easily tell how much the charger is capable of doing before you even start. Samsung and Apple chargers are great at performing their stated ratings given the correct cable. Even car chargers perform as rated as well. My laptop for example output .8A on USB 2.0 ports.

Cables on the other hand varies greatly. I have 2x 6 inch cables, 4x 3ft cables, 1x 6ft cable (note 2 authentic cable). All these cables failed me except the authentic Samsung cables and the two 6 inch cables. The lesson I learned is cable length (longer is worst unless its a good design) and thickness matters, 3 of the 4 3ft cables are .5A .6A .7A max. Only the Blackberry cable manage to get 1.2A max. Still far short of Samsung authentic cable of 1.8A Max. If you are disappointed with your charging rate, look to your cable. Replace it when an authentic cable if you are able. My best advice is this, if you are able to locate a fast charger, 2A+, with a non-detachable micro usb charger - buy that. It will save you a lot of hassle. This is especially useful if you are looking for a good car solution. You are somewhat "guaranteed" to get a fast charge from such a device because the manufacture already choose the correct cable for you.

I also have a phone dock, while it looks great, it is a cheap phone dock from ebay. It turns out, even when I use authentic cables and 2A charger, the current is limited to .5A. I had no idea!!

In these test, I did not use any "charge only" cable or mod.

Yea I used htc one x charger as well and it was better, something around 900 but it wasn't as stable as the current from galaxy s2 charger, which was giving a stable 900 from the moment I started to the moment I stopped charging my phone.
[Android Software Development] abmantis:
The names of the three values (now, avg and max) are the ones from the files provided by the system and from which I get the values.

So the app gets the value from a current_now named file and displays it. The decision on what value gets on the file was made by Samsung, not me :P

I don't know any app that would let you monitor the real actual current. Also, if I ever find a way, I'll add it to the app.

The version on the market version is wrong. I'll correct it in a next update.

The pictures you indicated showing its working 100%.

I agree the label of these items can be enhanced to be easier to understand.

"Current_now" is binary: 999 (AC) or 466 (USB) charging.

"Current_avg" is accepted charge: It ranges between 460 - 600 for for you based on the cable/power source combination.

"Current_max" is attempting to charge: again it ranges between 460 - 600 for for you. You should see this number spikes when you first plug in the power source. Eventually it will settle on the same number as Current_avg. Each spike indicates its attempting to request a higher charge from your cable/power source, negotiating whats the maximum stable charge.

Could you change or provide alternate labels of these items to be :

"Current_avg": "Accepted current rate"

"Current_max": "Attempting to charge rate"

or something to that affect.

Re: Check if your device is charging correctly

I sell a "iPad USB Adapter" that is a USB A m/f adapter that when plugged into the USB Port of a PC removes the 500mA limit. I tested it with my Note 2 & this app. Here is what I got :

Adapter: - without. - with

Now: - 466. - 1698

Max: - 460. - 500

Avg: - 460. - 500

I leave it to you to tell me if this means that my Note 2 is really charging at 1698?

There is a "Samsung" version of this out there, I will have to get one and see the difference.
[Android Software Development] inspron:
Simple answer is NO. Please read my prior posts. 1698 simply means its charging as "AC", nothing more. Your actual charge is 460 or 500, which is really low.

AGAIN and AGAIN and AGAIN. Its your cable that is your problem 90% of the time. Use the same power adapter with Samsung original cable and you can see your charge rate jumps up to 1000 or 1800. Cheap cables is your problem. Prior to this app, you have virtually no way of knowing how much your Note 2 is actually accepting.

Current_Avg is the only value that matters.
[Android Software Development] rrjay:
abmantis,

Thanks for this post (I got to it from Temasek's thread).

You are spot-on correct about different cables. I just got back from overseas trip where I experienced prolonged recharging of my phone (it seemed like 2 or 3x longer). After reading your this thread, and using the current app, I found my usual home cable/charger setup charged at 1000mA, but the overseas cable I used max'd at 500mA with same charger (2,000mA output charger).

I also found that with an old Apple iPhone charger that I took on the trip for it's small size (and now I see only outputs 500mA max) and this same, cheap cable, the current charge was only 300mA. No wonder it took many hours to charge my S3 on the trip!

Now, I'll check my setups more carefully.
[Android Software Development] ImS0Raw:
That's not fully true. My Samsung Cable isn't some kind of cheap crap huh but it is what causes my charging problem! Conclusion: Samsung is pretty much crap if so many users complain about this issue. Not only this, I regret I bought the Galaxy S3, beside these little things it's a great phone. Loool, I'm going off-topic, oh btw, fanboys don't start attacking me :eek:
[Android Software Development] inspron:
I somewhat agree with you, just because it is a Samsung cable, it doesn't make it a great cable. I have pulled my hair out on this charging issue for a while now. Initially I thought my power adapters are bad, then its the phone, with this app I found that my cables are the culprit, pretty much all my cables varies widely. It just happen that the Samsung cable that came with the phone was the best of the bunch and consistently so.

I still can't tell if its Samsung phones that are "choosing" to be picky about the cable or all phones have this issue.
[Android Software Development] ziemboy:
Ok so basically what I'm experiencing atm is:

-stock charger + stock cable(about 0.5m I think) and I'm getting different values everytime I plug in the charger, just now I did it and what I got is max 300, then I unplug and plug again and get 400, again the same and get 300, 200, 500, 800... after replugging the charger 6 times It's set to 800 and would get different value...

Unfortunatelly after a few mins I clicked refresh and it shows 500 atm, then again goes to 400 in a couple of mins.

When I plug in S2 charger which is a one piece charger I get constant 900. Weird thing going on.
[Android Software Development] inspron:
How long between your plug tests? It usually takes a few minutes before your current_avg to stablize. I definitely agree with you that one piece charger is the way to go, thats why I recommend that in a prior post. I also have a one piece 700 rated charger. Sure enough, that is exactly my charge rate everytime.
[Android Software Development] ImS0Raw:
Now I got a good quality USB cable (19 euros!) but my phone finally charges normal at 1000! I'm satisfied and it was worth the money!
