The iFixit kit to replace the battery in S10 worked fine, including the heating sausage. Jus need to take your time and take great care to follow the instructions in order. The most stressful bit was getting the new adhesive in the correct spot to achieve a flawless finish. It is brilliant that these phones are repairable and that there is so much support for same. Shame on you Apple. We have to stop throwing repairable things away, both to save money and to save the planet. Thanks iFixit.
