Maybe someone else will tell you something ..
Since the model of the tester is unknown, there is one more assumption - the smart is charged with fast charging, but the tester does not support it and then the readings can be halved.
Now a few of his observations and what he read in the vast neta.
There are many references such as why buy expensive and cheaper if you can do the same. Disappoint in this regard. Cheap enough that almost nothing can do (as mentioned, most of them do not support the fast charging and naturally half capacitance value). Plus, besides reading the review, the guy has tested several models of reel stands and not in a single copy. Couple models it tested by 10pc. And readings differed more than 10%, just do not remember (it was between instances), and do not sootvetsvovalo reality, ie lied. And where is the confidence that you got more or less a decent copy. So that they can be used indicator type and about any evidence or the accuracy is not worth mentioning. As for me more or less can be trusted tester J7-T (I roughly know the state of Batteries in their smarts and some reference points. In this case I had for the first time 4 different testers and I opted for the J7-T. Later, a model with Oled an indicator, but it did not solve anything but colorful. and there were only a couple of interesting models in recent years.
I will not say anything about the RD UM34C + HD35 kit, an interesting solution to the mid-price range.
Recently I paid attention to a couple of interesting models, as for me:
J7-C (DC) with Bluetoothand
RD AT34, bundled with a load HD35 look very dignified.
Their dignity include:
1. support fast charging and with almost all protocols: heap, samsung, mtc and even huyavay. Who does not know, I will say that the flagships of huavei fast charging is not done by increasing the voltage, but by the current, there is a 5Vx4.5A mode, and now they implement 45W charging at all (they have already increased both current and voltage).
2. Both charges support USB pass-through, i.e. they can be used in OTG mode as a signal, they support both USB 2.0 and USB 3.1 protocols, i.e. You can use a flash drive or an external screw as a drive so you can simultaneously measure battery consumption by them.
3. If you connect a load instead, you can measure the capacity of the built-in battery for discharge.
4. When checking the cables measure the internal resistance.
Here are the main advantages.
For the time being, I chose J7-C, why is it, firstly I have smartphones and micro usb and type C, i.e. will not have to use adapters. Secondly, bluetooth, there are only 2 memory cells on the testers themselves, and with bluetooth, you can save a battery database on a smart (with a single measurement of accuracy you can’t reach it).
That's where it is. Happy New Year and success and good luck.
