is that coincidence that when Apple releases a new line of phones then the models 2 generations behind start to develop annoying things, such as: battery drains quickly, buttons don't recognise tapping immediately, lag in operation and general slowness... It looks like Apple push out and activate a "sabotage agent" hidden in any release of iOS when a few newer models are out there. So people eventually get fed up with the annoyance and just chose to buy the latest model. I'm not talking about iOS upgrade. To say an example: bought my iPhone 4 with the original iOS. At that time iPhone 5 series were out on the market. I haven't updated software, have used the very same apps in a very same way, but after the new 5C etc were released my phone started to act up suddenly. Running exactly the same things... battery gone in about 4 hours average use. The phone wasn't even 1 year old when things started to go slow. Anybody has any facts or opinion about this? Greg PS I intend not to offend any Apple products here, I am a great fan of them.
