Happy New Year, everyone. Long time lurker shaking off some dust!
I know we talk a lot about batteries; however, I have some questions about what I'm gonna call "The iPad falloff."
I've had an iPad 4th Generation for literally a decade now. I don't use it as my daily driver anymore, but it still gets some use as a music streamer, remote and alarm clock. The battery even after a decade is still holding up really well. The standby time is legendary. I charge it around once a month. When I made the upgrade to an iPad Air 4, I was expecting to be blown away, but alas, I am not.
iPad 4 drains around 1% per day.
iPad Air 4 drains around 1% every couple of hours.
So every time I read battery threads, the automatic thing people say is "turn this off, turn that off" and it shouldn't be that way. I haven't turned anything off on my iPad 4 since 2012. (Wifi is always on, email fetch is on, Bluetooth is on, Hell even background refresh is on.) Battery life isso damn good, I didn't have to turn anything off. Even the generational jumps from iOS 6 to iOS 10.3.4, just amazing.
The next argument is "iOS 10 is ancient, iPad OS 14-15 has way more features" This is a gray area depending on how you perceive ancient. There's still some decent support for app updates. iOS 10 itself was no slouch. There was way more going on in iOS 10 versus iOS 6, yet... battery hasn't taken a hit, like at all. Let's not pretend that iOS 10 doesn't have some of the same core features as iPad OS 15.
Moving on to the iPad Air 4. My expectation was really high, and after my first night with it, I was confused. A 5% drop overnight is a lot compared to a 1% drop for an entire day. I always update to the latest OS whenever possible, especially for a new device, so I chalked it up to extra background processes because of the update. I wait a week. Same thing.
The next argument is "The A 14 Bionic is way more powerful than the A6X". True, but after a decade, shouldn't power optimization gains play a role as well? A 14 Bionic has a 4 x 4 (Power x Efficiency cores) the A6X just has two cores. No fancy Firestorm or Icestorm magic.
I guess my expectations on those Icestorm cores were way too high.
Then comes iPad OS 15. Low Power Mode. First time ever on an iPad. So a newer iPad + newer OS + Low Power Mode can surely beat out a decade old iPad with none of this stuff, right? Low Power Mode took drain from 5% down to 3% with the same settings as my 4th gen.
Not bad, but spending the amount of money I did, I was expecting so much more.
The next group of people are the "just charge it" crowds. The whole point of this thread is I barely ever had to charge it in the past. lol.
Now I have to do it once a week, roughly. That's terrible for an "iPad", especially considering it's just sitting in standby most of the time.
And it's only gonna get worse as the device ages.
I will say, on screen time is decent. For people like me who like to hold on to devices as long as possible, standby is even more important. The better the standby, the less I have to charge, which equates to less wear on battery, which equates to a device I don't have to replace for the next decade to come.
Gonna close the post with these questions. "What the F happened?" What is going on in iPad OS behind the scenes that just killed off the former standby behemoth?
