So, a week later I have started to notice that my battery life has definitely improved. Apparently some sort of indexing must’ve continued for a longer time than I expected.
Last weekend I didn’t have to charge my phone from Saturday around 11 AM to Monday at just after 12 PM, with still 26% left. Even though my usage wasn’t like heavy or so, I’m still very, very impressed. First time ever since owning an iPhone that I last two days without needing to charge.
And today and yesterday, battery life has been great as well. Yesterday for example I took it off the charger at 6 AM with 90% juice left. When I went to sleep at around 12:30 AM, it had 40% left, after what I’d consider medium usage.
This is the kind of battery performance I was rooting for. Hope it sticks like this!
