I feel the same applies to Macbook as well. I've a Macbook Pro Retina 13 inch, early 2015 at a battery cycle count of 1001. From the last few weeks, the system is terribly slow. I randomly see the fan speed going berserk. :/

Might be something wrong with your SMC or thermal throttling going on. Either way I'd suggest resetting the SMC and if that doesn't fix it check out Activity Monitor to see what's wrong.

Nothing really. I did reset the SMC couple of times and also check the Activity Monitor every time the fan speed increases, but to no avail.

Looks like I need to replace the battery as it's near it's end of life - https://support.apple.com/en-in/HT201585

Apple has decided that people want to buy razorthin phones and there is just not way to fit a large battery in there. I wish there were phones built like the old IBM thinkpads. Bulky, square, ugly but also indestructible and fully user servicable with replaceable batteries.

If the battery capcity could be increased to the point where I didn't need to worry about charging it every day (night), like an old feature phone, then I would see the point. Otherwise I'm agreeing with apple - let's make the hardware faster and the screen brighter instead and just make sure the battery lasts a whole day. Having e.g. 50% more battery wouldn't do anything for me. It would save me that one day per yea…

> and just make sure the battery lasts a whole day.

But the problem is that the iPhones seems to last a day only when they are new-ish and there is no safety buffer down the road. If it is fine on release day it will not be fine after 2 years if there additional capacity build in.

The solution is a battery you can replace, like every phone used to have. There aren’t only two solutions to this problem. (Technically you can still replace the iPhone battery, unfortunately it isn’t trivial like in the bad old days when phones didn’t have high def touch screens.)

I replace my iPhone battery with a cheap one off eBay every year or two when something else breaks. Battery life is pretty good, but the screen pops up now making the phone 0.5mm thicker. It's doing OK for a 5 year old phone, but my friends can't believe I paid $800 for an iPhone 5.

A great way to increase the odds of an explosion near your face or office desk!

I feel like more transparency would have been welcomed, but aside from that this is a "no win" situation, since you have to pick a winner: - Do you degrade performance but leave screen-on time relatively unchanged? - Do you degrade screen-on time but leave performance relatively unchanged? Most Android devices seem to do the opposite (lose screen-on time, but keep performance relatively unchanged). Different people w…

You make your phone buying decision based on the advertised performance of the device. To sell you one level of performance then subtly take that away I would call dishonest.

> This post is written as if it wasn't Apple that introduced the hard-glued battery. They made a consumable hard to replace As others have pointed out in this thread the batteries aren’t hard to replace; this is just not something you can do directly as a user. That probably makes sense; it’d be difficult to make a super-thin smartphone while at the same time provide an easy way to replace each part.

The problem isn't necessarily the replacement, even though it's certainly not for a large majority of iPhone customers. The problem is sourcing the battery in the first place. Apple certainly isn't supplying any of them. In the best case you get one that works properly, if you're unlucky you might get one that has lower capacity, and if you're very unlucky you might just get one that puffs up and catches on fire.

> The problem is sourcing the battery in the first place.

Not really! iFixit and others have done the hard work for you there (I work at iFixit).

> This will likely feed into the “planned obsolescence” narrative. well, non-replaceable battery and all...

It's replaceable, just not as a DIY. Apple encourages people to take their phones into Apple stores/authorized dealers to get the battery replaced. (Also, the repair is free if the battery's capacity has declined to <80% while under warranty. If you pay for two-year AppleCare+ [$99], you've basically pre-paid for a free battery replacement [normally also $99] at the two-year mark, as long as you've used—abused?—your…

Not in my experience. Bring your iphone to an apple shop and ask for the battery to be replaced. Apple will most likely refuse unless the battery is shown as severely damaged in the settings.

Could be dirty. Google a cleaning guide for your model, the fans get all sorts of dusty and it causes thermal issues.

Why does this correlate so well with iOS version increments?

My iPhone 6 was faultless prior to the upgrade to iOS 11, and immediately after it battery life was greatly reduced and it now shuts down automatically when the battery hits 10%.

Apparently I am now supposed to accept that the battery has degraded not gradually but all at once and on the same day as I upgraded iOS, and this is now being managed for my benefit by the OS. Hmmm...

Related: If you have a Mac, you can check the health of an iPhone battery via the Console app when the phone is connected via USB. Search for the string "BatteryHealth", logged by the phone's Springboard process.

"Battery Life" (Free) on the AppStore is good for checking stats as well.
