Samsung launched the Galaxy Note 7 again as a refurbished device called the Note Fan Edition (Note FE) on July 7. The device was torn apart by iFixit, which specializes in device teardown.

iFixit, a private company in San Luis Obispo, California, published its findings Thursday revealing why the Note FE and the Note 8 may not go up in flames like the Note 7 — it comes with a different battery. The manufacturing date on the battery of the unit torn apart by iFixit was shown as June 20, which means that the battery was manufactured fairly recently.

The teardown revealed that the Note FE battery is also 2.3 grams lighter than Note 7’s battery.

The reason cited by Samsung for the Note 7 explosions last year was the exposure of batteries to ambient air. This was a basic oversight in quality control which caused the scandal. According to iFixit, it put the battery outside of a safe operating zone as happened with the Note 7. The difference in the size of the battery accounts for any swelling and crimping issues occurring due to any such oversight.

Samsung is expected to keep the battery smaller in the Note 8 too – it is expected to have a 3,300 mAh battery in comparison to a 3,500 mAh one, which was used on the Note 8.

That being said, the Note 8’s battery is slightly larger than the Note FE’s 3,200 mAh battery. The reason for this is that it is expected to have better hardware than the Note FE and obviously the Note 7. The device is expected to launch with the Qualcomm Snapdragon 845 processor, which will be an improvement on Samsung Galaxy S8’s Snapdragon 835 processor. Both the processors will be based on 10-nanometer processor technology, which will ensure better performance and more importantly, in the context of the Note series and better power usage.

10nm processors perform better than their 14-nanometer counterparts since they accommodate more transmitters, which creates a more efficient distribution of power and a more focused performance.

While iFixit couldn't delve deeper into the Note FE battery into finding out the technology used, there is no doubt that the company has learned a lesson from the Note 7 scandal.

A recent experiment conducted by YouTubers — “What’s Inside” and “JerryRigEverything” on the Samsung Galaxy S8 revealed that the battery is actually capable of surviving and slicing, unlike lithium-ion ones used in previous Samsung smartphones. During the experiment, the battery did not explode. However, it swelled up, following which a transparent liquid leaked from it, indicating Samsung is using some kind of mechanism for avoiding explosions.

While Samsung hasn’t made any announcement about the battery technology that it is using in the S8, our estimation, based on the result of the experiment, is that it is using LG-style thermal cooling pipe technology which keeps the batteries from exploding even when they face heat and resistance.

If you are considering on buying the Note 8 when it launches, the battery might be something you need not worry about.
