The plaintiff claims that apple's fault lies in three things:
1. Take the weakened performance to prolong the battery life and prevent accidental shutdown, without informing the user in advance;
2. Users who choose to replace new models because of their slow performance are being cheated.
The iOS update does not include a description of the weakening performance, nor does it remind users that they can choose not to update to avoid the performance being weakened.
In addition, some users have said that they are basically disappointed with apple and will switch to the android platform in the future.
