ok there is a simple solution to all this
Apple make a patch to remove the illegal practice they have put in place , then they compensate all iphone and ipad users they have affected. If people purchased a new phone or new ipad as the old one was SUDDENLY too slow , apple have to reimburse the customer for the price of the device that the customer just purchased, based on that without the APPLE illegal code slow down the users would of have not purchased a new device as it was working just fine at the speed that was required. So that this can NEVER be used as excuse in the future all new devices have to have sensible battery monitor ic's embedded (these ic's are around what 2$ max ) should be able to fit that into a device with a 1000$ Build order without adversely affecting the build cost . Apple knew what they where doing was wrong or they would not have tried to hide it for so long, they have only come forward now as a class action law suit has been filled against them or they would have continued to rip off the customers until someone noticed.
They are thieves , they stole functionality from users in that there devices became almost unusable which was timed to coincide with new product releases , to force the old device to become obsolete . This is not APPLES choice to make they should not have tried to manipulate the market , now to be honest they deserve everything they get from the class action law suit (including bankruptcy ) this needs to really signal all players of hardware that rip off your customers and there will come a day where you will pay DEARLY.
