For some models, the battery includes the NFC (Near Field Communication) antenna. Using a non-Samsung battery where the model has the NFC antenna built-in to the battery may mean that NFC will stop working.

How much battery does NFC use?

2 – Does NFC require a battery? No, NFC-embedded objects do not need a power source. An NFC chip is made up of a small storage memory, radio chip and an antenna. To work, NFC chips leverage the power of an NFC reading device, such as a phone.

Where is the NFC antenna on my phone?

Depending on the make and model, your device’s NFC antenna might be located along the top, middle, or bottom of the backside of your device.

Do Samsung batteries record you?

He says that this is spying on every phone user and “recording every photo of yours.” He also urges folks to remove this unnecessary part of the battery and his proof is that the phone still works without it. …

Does NFC save battery?

Unless you use NFC many times throughout the day, having it enabled won’t have a huge imparct on battery life.

Why does NFC use so much battery?

Well, NFC of course uses electricity, energy and thus takes that energy from the battery. On the other hand, NFC is designed to be a relative low energy feature on current smartphones, so, it is a very low probability the just NFC will deplete the battery of your smartphone.

What is inside Samsung battery?

Can magnetic fields damage NFC antennas on smartphones?

The answer is yes – if there is no metal or conductive material around the NFC antenna. However, the NFC antenna illustrated in Figure 1 is on the back of a smartphone, which is metallic. If you know much about electromagnetics, you will know that a ground plane directly beneath magnetic or electric fields will very much degrade them.
