Is Your iPhone Running Slow?

Replace the Battery and See Speed Increases

If you had, or have, and iPhone 6 or 6s you might have experienced this problem.  You’re going about your day, barely using your phone, and when you check it you have around 30% battery left.  Irritated you get online and try to see what’s going on with the device.  Suddenly, battery life drops to 1% and a couple minutes later it powers off.

Alternatively, you may notice that with those same models, you have experienced an extreme slow-down after updating to the latest iOS.  While newer releases of the software are going to slow down older phones a little bit (they’re designed to run with the greater processing power of the new phones), you really shouldn’t be noticing a huge slow down until your phone is considerably old.

There’s new “research” that shows it might not be the phone or the software; it might be the battery.


Battery Replacement to Speed up Phone

Last year Apple admitted there were battery problems (those were causing that first issue relayed above).  They offered replacements for quite a few phones, but only those of the 6s model.  Those of us who had the iPhone 6, although we were experiencing the same problems, were left paying for the battery replacement ourselves (despite hours on the phone with Apple where they suggested to go to extremes like reset to factory defaults and wait for 3 days to see if the problem persisted, then restore via iCloud; ain’t nobody got time for that).

But that still doesn’t determine why these models slow down immensely after updating the software.  Or does it?  Apple claims that iOS 10.2.1 resolved the battery issue by tweaking the software.

According a recent thread on Reddit the battery issue could still be the source.  It turns out that the user TeckFire noticed the issue.  After a series of tests that resulted in scores far below what he should have experienced for that model, he speculated that:

Many people might remember that iPhone 6S battery fiasco, which for many, was fixed with iOS 10.2.1, and that seemed to be the end of it. Apparently, the way it did this is by dynamically changing the maximum clock speed relative to the voltage that the battery is outputting, so that your phone can’t draw too much power and shut down.

What’s that mean?  It means that instead of fixing the issue (replacing the bad batteries), Apple covered it up by creating a software tweak that makes the phone run slower if it can’t draw the power needed from the battery.  No more random shut downs, but also long waits when loading anything.


The Test and the iPhone Battery Replacement

So we don’t want you to bring you phone in and spend the cash on a new battery if you aren’t running at a “lower clock speed”.  Fortunately, there’s an easy way to test if you’re running slowly. 

There’s a free app called CPUDasherX.  It’s simple, and it gives all the details for your iPhone.  A screenshot below with the top of the screen on the left and scrolled down on the right:

Check your phone's processor speed

Notice “CPU Frequency”.  That’s how fast your phone is running (this is with a 7+ model, so it’s at 2.3GHz or 2339MHz).  If you have an iPhone 6 you should be running at 1.4GHZ or 1400MHz, if you have an iPhone 6s you should be running at 1.8GHz or 1800MHz.  Download the app and check your speed, if you’re experiencing these problems, you will likely see speeds around 600MHz.

If you are experiencing a slow phone, and your CPU Frequency is much lower than it’s supposed to be, then a battery replacement from iDoctor might help solve your issues.  We say “might” because there are no real hard tests on this yet.  If it doesn’t work, we can’t refund the cost of the battery replacement, but at $59 for an iPhone 6 and $69 for a 6s, you’re not out huge amounts of money.
