Sealed unit battery replacement. I have a Nokia 6, model number TA-1033. Every time I need to get a replacement battery it takes up to a week to get a new battery delivered, stock and delivery delays pending, and then almost every time there is an issue with the device afterwards. There are only two repairers in Hobart and I am not prepared to pay to post my device interstate. First time it was the re-sealing of the unit, and the battery type itself, now it is the home button and touch buttons either side. My complaint is that the sealed unit design is flawed, because of the problems related to battery replacement. I am aware of the reasons for this surrounding the environmental proofing, but the problems far outweigh the benefits.
