Does Apple slow down your old iPhone to make you buy its new costlier iPhone 8 and iPhone X?
If you have checked properly you will have noticed that your current iPhone has become appreciatively slower.
Mind you both the new iPhones are priced excessively high.
This is not the first time Apple has done this.
The latest version of iOS 11 doesnt support the older iPhones making them obsolete.
As said above, Apple has been accused of doing this earlier also.
Apple consumers had already created an online consumer group to fight this menace.
It never dealt with the technical angle about the accusation.
They tend to notice the performance issues more just around the time of the release of the new model.
