Samsung Galaxy S8 Battery Teardown – Important Points You Need To Know [Shocking]

Samsung Galaxy S8

After the launch of the ill-fated Samsung Galaxy Note 7 in 2016, Samsung has recently launched the flagship Galaxy S8 and Galaxy S8+ smartphones. The handset was initially launched in the US followed by India on April 19.

The first impression after using the newly launched Galaxy S8 is that it sports a design identical to that of the Galaxy Note 7. Moreover, the device features buttonless physical home control and bezel-free display. iFixit recently did a comprehensive teardown of the Samsung Galaxy S8 and forwarded to us the results.

According to iFixit, Samsung has not changed anything including the placement of the infamous battery. The teardown gurus at iFixit felt that Samsung will change the design and layout after deadly recalls in 2016. However, the company hasn’t learned any lessons when it comes to the battery.

You will be shocked to know that the Samsung Galaxy S8+ battery voltage, capacity, and design tolerances are similar to that of the Galaxy Note 7. Interestingly, the review unit received from Samsung by iFixit included the battery manufactured by the same company as the Galaxy Note 7. Hence, you should be very careful while adding the product to the cart.


According to Samsung, the problem with the Galaxy Note 7 was related to a manufacturing quality assurance. However, the Galaxy S8 features a glued-in battery. However, the installation position, spacing, and reinforcement are very much identical to that of the Galaxy Note 7.

If you look at the battery in the Galaxy S8, it is deeply buried in the phone. You will not be able to remove it easily since the battery has been firmly glued down. You should note that battery glue was not the reason for the explosion of Galaxy Note 7. It was a manufacturing error that caused all the fiasco.

The iFixit team revealed to us that glued batteries are very hard to replace in the future in case of any necessity. Moreover, you will have to shell out huge money to replace the battery.

Samsung Galaxy S8 and Galaxy S8+ teardown highlights

Samsung Galaxy S8+ features a 13.48 Wh (3500 mAh at 3.85 V) battery, which is same as the Galaxy Note 7. The capacity is less than the Galaxy S7 Edge, which has a 13.86 Wh battery.

Samsung Galaxy S8 is equipped with an 11.55 Wh battery, which is equivalent to Google Pixel’s 10.66 Wh battery. If you look at iPhone 7, it has a 7.45 Wh battery. Hence, the Galaxy S8 is excellent in terms of the battery. It remains to be seen as to how safe the device will be.

The fingerprint sensor in the Galaxy S8 series is placed in a controversial position. You will have to blindly stretch and blot out the camera to work with the fingerprint scanner. The NFC antenna, which performs Samsung Pay functionality, makes use of a coil as an electromagnet.

When it comes to the iFixit rating, both Samsung Galaxy S8 and the S8+ has earned 4/10 on their repairability scale. The main reason for the 4/10 rating is due to the integration of a front and rear glass design, excessive use of adhesive including the addition of a curved and difficult-to-repair display.

If you purchase Samsung Galaxy S8 and Galaxy S8+, the handset will be difficult to repair in the long run. That said, Samsung Galaxy S8 was launched in India on April 19. The handset is available for purchase at Flipkart for Rs. 57900 (Galaxy S8) and Rs. 64900 (Galaxy S8+) in Midnight Black, Maple Gold color variants.
