The program covers a vast array of battery types, with phone batteries being a popular section, which covers lithium-ion battery types. However, there are so many different types of phones and just as many unique batteries made specific for each style, brand, manufacturers, etc. So, it’s hard to answer this question with a quick yes or no. There are some brands that have also made it near-impossible to remove the batteries (probably because everyone was learning how to repair them on their own and taking money away from the business). The good news is that there are plenty of tutorials out there (like in Youtube) that will teach you how to remove and dismantle difficult phone batteries. Then, this program teaches you the rest.
