The Competition appeals tribunal will hear that Apple misled users over an upgrade that actually worsened iPhone's batteries resulting in some users upgrading early or paying for a replacement battery. The upgrade affected models from the iPhone 6 to X.
If the claim is successful consumers of those models of iPhone would be awarded between £30-£60 of compensation for each iPhone they owned. Other users could be entitled to more if they replaced batteries or the whole device due to the perceived degenerative performance.
The claim is currently valued at around £1.8 trillion and alleges that Apple abused its dominance in the market and engaged in exploitative and unfair commercial practices.
It will be interesting to see what happens and how the decision affects consumer rights law.
