It’s amazing how fast an iPhone battery deteriorates in only 3 or so years of use. The photo in this post is from coconutBattery which is an app that I use to monitor the battery for my MacBook Pro. The added benefit is that I can see the battery performance of an iOS device (it only works with the later ones, I tried it with an original iPad and didn’t get any data back). Anyway, the phone above belongs to my wife and just this past week the phone would start turning off once it hit 40%. Puzzled by this I decided to do some Googling to see what the problem could be. This issue is pretty common with devices on iOS 10, especially the iPhone 6 and 6s. I tried everything I could to see what was the matter and fix it short of blowing the entire phone away and reinstalling it app by app (its not my phone so I don’t want to do that).
The other thing we just tried today was to install the iOS 11 Beta 6 release. This solved one problem which was to show the true battery level on the phone. Now I can see that the battery level is at whatever percent and lets my wife know that she has to charge her phone up so it doesn’t turn off. As the picture above indicates though, her battery is roughly at 50% of original capacity which translates into 5 hours maybe of web surfing and maybe 2 hours of talk time if she uses the phone. Thats pretty shitty by any measure especially for an iPhone. Now the thing thats in her favor is that the iPhone event isn’t that far away, maybe a month and hopefully she can hold out until then so we can get an iPhone 7s or an iPhone 8 (depends on what Apple decides to announce in September).
As a stop gap measure we’re trying to remove data from the phone so that she can use my old iPhone 6s that I had for work. The issue is that the memory on the 6s is half of what she currently has (64 vs 128) so when I try and do a restore iTunes doesn’t like it and decides to just stop doing the restore altogether. Not very ideal, I wish there was a way to be selective on whats restored and you can do it via third party app but I have no desire to install more bloatware on my MacBook Pro if I can help it. I’m going to keep plugging away at this issue, probably more this coming weekend during Labor Day since I’ll have some extra time and I’ll crack it by George or we’re getting my wife a new iPhone (well we’re doing that anyway, her phone is kinda OLD and she needs a better camera to capture those precious memories while I’m away).
