Ios 9.1 was so frustrating and the battery life so awful lately that i was seriously considering ditching my iPhone 6 and returning to a HTC One M8.
But after updating to ios 9.2 last night, i tried a app launching test between my iphone and my gf's iphone 6 running 8.4.1.
While i did notice some animation stutters on my iphone and sometines apps would load a fraction of a second faster on her phone, once I started relaunching apps from the app switcher on both phones, i understood how indeed ios 9 might be actually better than 8.
While only one app reloaded on my phone, all but one reloaded on hers, so it seams that iOS 9 is way better with RAM management. After a day, battery life seams good enough too. Unplugged my phone 12 hours ago, still have 60% battery with 3 hours usage.
Anyone else seeing ram management improvements?
