Is my charger not working 100%efficient?

I have N9005 MJ7 rooted
iam using galaxy charging current pro, to measure my charger output, but with my phone gives only 1200mah, while our charger should gives 2000mah, iam using the original charger and cable which came with the mobile
is it normal, does anyone got a better score? which apps do u use?

i get that as well dont think charging current pro is compatible with note 3 so dont worry about it :silly:

That app is OK and probably your charger is also OK - the circuit that controls charging is probably limiting the current in order to keep it safe (for instance if it is too warm it might use an even lover current). Also the current is optimized as to be different at different levels of the battery capacity.
That being said I am always charging over night with a safe USB port - that way the current is 500mA max and the battery life is maximized, while I still get a completely full battery in the morning.

I have a friend who has a 3 month S4, he used to leave the battery charging over night also, and the battery swollen and life daily use decreased to less than a day in 3 month use only!!!

Yes, but:
- the S4 does not have the same charging algorithm as the Note3
- he was probably charging the S4 (which has different battery, charger and algorithm) at 1000 mAh or so (which was the most important point I was making, the 500 mAh are not 2x safer, are probably 4 to 8x safer, probably 20x safer than 2000mAh, that is not a linear thing)
- I think the S4 batteries had a certain defective batch (the media spoke at some point about it)
- there will always be a certain very small percentage of batteries that WILL go bad "no matter what", but that is usually exceedingly small if the charge process is done correctly.

Z3C Battery Charging Thread

Hiya,
I' hoping this is the right section to post this in.
I don't have my Z3C yet, but I've been searching for information on charging speed, charging current etc. - and there is barely anything to be found. What seems to be consent: A full charge (0-100%) takes about three hours. But then, some people say an almost full charge (0-90%) takes much less, as charging current is greatly reduced for the last 10% to reduce stress on the battery. Sony itself also claims that a small charge (something like 0-10%) should be quite fast as well.
Then there's some speculation about QuickCharge 2.0 being used or not used, that you could use a Motorola 2.0A charger to charge it faster than with the provided 1.5A Sony charger etc., which also brings up the question which resistor values on the D+ and D- wires are necessary to toggle different charging currents. (Or I might be stupid and there's a standard for that by now, which is the same for all Qualcomm devices.)
To cut it short: I'd request those who have a Z3C to post some comments about their charging times, and at best even their charging currents. I used an app called BatteryMonitor on my Desire HD, I'm sure there's others around now that give the same information. If someone could try out different chargers and record charging current over time, maybe even with a pretty graph, it'd surely help all future discussions about chargers, docks, modifications, DIY charging issues etc.
[EDIT] I've created a similar thread over at the Z3 forums, as many things (such as resistor values and charging tactics) should be similar.

With the 1.5A charger it's almost the same speed as other flagships: about 1% per minute or so.
For quick charge, Qualcomm explains it here: https://www.qualcomm.com/news/snapdragon/2014/06/04/quick-charge-20-has-arrived
Because it's more difficult for me to get the Moto Turbo Charger from where I live, I ordered another quick charger on the list and will see how it works.
Hope I will have time to report soon.

Sorry for the delay. It's obvious that QC 2.0 works only when battery is really low. Not sure it's Sony's control thru hardware, or kernel, or charger's control.

share your Ampere/ "charging test" results (investigating lollipop charging issue)

share your Ampere/ "charging test" results (investigating lollipop charging issue)
I created this tread so people can share their Ampere/ "charging test" results (with service mode) so we can analyze the data and get a better understanding the charging patterns.
To access to "charging test" in service menu (in d800 dial 3845#*800# and select "charging test") (replace 800 with your model if you have a different G2 variant)
With stock 1.8A charger with stock cable I'm getting only like 300mA to 500mA (cloudy 3.3, stock kernel).. getting the same kind of results if I use the tab2 2A charter too.. I got the same kind results with stock 5.0.1, stock Kitkat 4.4.2 with dorimanx kernel, Dirty Deeds roms. With this rate phone could take up to more than 3hrs to charge.

but with my Palm 1A charger I'm getting like 900mA to 1100mA most of the times.
Can you guys please share your results too ? so we can get a better understanding what's going on here. you are more than welcome share the results of your other android devices too. please mention the OS, kernel, charger, cable that you are using when sharing your Ampere or "charging test" results.
thanks.

Battery percentages varies time to time, depends on device n its provided charger. When Battery is near empty, it charges at higher rate and provided charger supplies current at higher rating.
For example; Battery below 15% suppose to charge 1600mA(Fast Charge), it does produce heat. Once it reaches to certain percentage like 50-60% it will gradually decrease from 1200mA, after it crosses 75% may go down a bit more like 700mA and once it reaches at 90% it will be set as around 350-400mA.
If you could notice, Initially device Battery temp. rises and gradually it decrease, because lower the supplying rate better for Battery as well as SoC.
Please re-upload attachments at around these level ~15% ~40% ~75% ~95%

I never got the 1600mA rate.. even when the battery percentage below 15%... here are some screenshots (with the stock 1.8A charger and stock cable)

Using Samsung Note 2 charger (2A), CloudyG2 3.3, stock Cloudy kernel.
Have you tried changing cables? Low quality cables can often impede charging speed.

Thanks for sharing your reslults..
Currenty I only have stock cable and stock moto g cable. I can't see much different results with those cables atm...
Btw are you getting the same results with the stock charger and cable?

I don't have the stock charger since I got the Japanese version of the G2, which doesn't come with any charger. I've tried it with another 2A charger of mine (used to charge my pocket WiFi) and it returns the same results AFAIK. The only time it charges slowly is when I connect it to a PC, and when I use an old 700mA charger from an old ZTE smartphone.

Can you guys share more results please.? It will only take few minutes.

no pic but today i tested mine. it didnt came with charger so i bought one from amazon. my brother gave me a lg charger rated at 1.2a. so i only got a usb cable wich i think it isnt the stock cable.. the cell was brand new but no charger .. so i got me this supposely lg 1.8 charger.. with usb cable tha came with 1.8a charger i get max 320 it goes up and down. with the usb tha came on the box of cell i get 1100. with a motorola usb i get same 1200.
with the 1.2 charger i get 900 1000. so i think the usb have something to do.. and i also noticed that at times at 900 unlpugging and plugging the charger it changes to higher voltages .. that also happened to my older cell phone i had the s2.. unplugging and replugging gave me more power on same usb cable..

Try dorimanx kernel and enable fast charge .......in normal i got 1600~1800 with 2A charger

LG G2 D802 vs. Ampere (App) compatibility?
LG G2 D802 - Android 5.0.2 - partially working, I think...:
During the use (discharge) of the device, the app always shows -30mA.
No matter the load, since turning on wifi, 4G, flashlight and anything....
During the device charge the value changes, and is sensitive to the load: wifi, 4G, flashlight... It shows reasonable values (200-400 mA), for me.
Q1) May be LG G2 D802 one of those devices without the battery drained current measurement circuit? (If so the discharge current may shows a fake value...)
Q2) Is there someone that already experienced this issue with D802?
Thanks

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 Redmi Note 8 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Can anybody please confirm that the phone does support the QC 4+ and not only QC 3.0 by testing charge with different chargers ?

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.

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?
