Typical misinformation. The lawsuits that worked are for Apple not informing people, not because Apple slowed down the phones. The ones that have been about the slowing down have either lost or been thrown out.

Also, your logic doesn’t make any sense. Are you saying that a slow phone is more likely to encourage someone to buy a new phone versus a phone that constantly dies at random times?

And if you wanted your phone back to full speed, all you had to do was replace your worn out battery. That seems like a dumb way to upsell someone on a phone if they can pay $100 for a new battery and have their phone back to full speed.
