How to distinguish s4 battery

Identification of S4 battery by voltage test method

Judging principle: Samsung S4, S3, Note and other series of mobile phones all use 3.8V lithium batteries, and the upper limit voltage after full charging is 4.35V Based on this, we can accurately judge whether it is the original battery. Why? Good question, because at present, more than 95% of fakes and high imitation electricity on the market are modified with 3.7V lithium batteries, and the upper limit voltage after full charging is about 4.20V V ... Because the full charging voltage of the battery is the essential property of the battery, it cannot be faked. So we can judge whether it is the original battery by detecting the voltage of the battery. That is to say, charge the 3.7V high imitation I9500 battery with a mobile phone, and it can display 100% power when fully charged. However, when the mobile phone stands by for a period of time, it quickly drops below 95%. Because the highest voltage of the battery is 4.20V, and s 4 determines that the battery voltage is 4.3V, which is 100%.

The above table is the reference standard. * * * There are two testing methods. As long as you have one of the following three tools, you can test it.

1. multimeter (not everyone will have it), a professional tool;

2. A Samsung S4 mobile phone (only the mobile phone can recognize it);

3. Seat filling, original seat filling or brand seat filling, such as Yubo and Pinsheng.

Methods 1- multimeter:

Step 1:

Charge the battery directly with the mobile phone (it can be charged when it is turned on/off). After charging the battery, turn it off and take out the battery.

Or use the battery holder to charge the battery.

Step two:

Leave the battery idle for a few minutes (for example, 5 minutes, if the battery is 4.20V, it will restore its essential characteristics to 4.2V).

Test the positive and negative voltage of the battery with a multimeter. If it is voltage

Method 2- Samsung S4 mobile phone:

Step 1:

Charge the battery directly with the mobile phone (it can be charged when it is turned on/off), unplug the power supply after charging and turn off the battery.

Or use the battery holder to fully charge the battery.

Step 2: (This method is effective for licensed mobile phones, and parallel mobile phones must pass the official system test, otherwise the error will be great)

Install the battery, turn it on, wait a few minutes (because the power load of the system is heavy, just like the voltage will fluctuate when the PC starts to load the system software), then open the dial-up interface and enter "* # # 4636 # * # *"-battery information. View battery voltage and battery charge information. If the voltage is greater than 4250mV and the power is greater than 97 (the fake battery directly drops below 97%), it is a genuine battery.

Of course, you can also install a "professional battery indicator Pro" (download it yourself in the market) to see what the battery voltage is, whether it is greater than 4.25V, and whether the power is above 97%.

Summary:

1. The authenticity of the battery can be judged by the fully charged battery voltage. This is because the nominal 3.8V high-voltage lithium battery is as expensive as the original battery, and 95% JS won't do it!

2. Not only the battery, but also the seat charger. Pretend to be the original 4.35V rechargeable seat charger with 4.2V high imitation Samsung seat charger.

This kind of high imitation agent charge is often seen in online shopping, and some people always comment that they are not satisfied. Moreover, Samsung original seat charger can definitely charge original batteries or 3.8V batteries such as Pinsheng.
