Still don't buy it.
1. 29 dollars for a year and then back to 79 dollars? LOL nice scam
2. I live nowhere near an Apple Store, closest one is and hour away. So what now?
2. My iPhone 6S's battery capacity is still at 80 percent, and ive had it since it came out in 2015. Yet my CPU has been clocked down to (single core score) 1500 (as I type this) and i've seen it at 1200 many times before. My (multi core score) is at 2400. For single core, this is more than an thousand point drop, and for multi core more than a 2 thousand point drop, from what it's suppose to be.
3. Apple can try to blame battery's, but in reality in just the last 3 months my iPhone has been trash. Mmm what could have happened in these last 3 months oh yea iOS 11 was released. How could my iPhone right before iOS 11 released, which was near its 2 year birthday work fine, and my "battery" so rapidly degrade after upgrading to iOS 11?
4. If Apple implemented these battery mechanisms in Janurary with iOS 10, why did I feel the effects (slow downs, lags) when I upgraded to iOS 11, 7 months later?
5. Can I opt out of these battery mechinism instead? I never had the problem of my iPhone 6S shutting down often. I would take smooth performance any day...
5. I'll say it again. iPhones CPUs and GPUs have become so powerful that the majority of the people who just use Facebook, iMessage, and Camera, wouldn't need to upgrade every year or even every 2 years. But Apple needs you to upgrade. So they purposely do these measures to slow down your phone. Or just purposely poorly optimize the code.
