You Can Speed Up Your Slow iPhone by Replacing the Battery

Posted on

All telephones decelerate over time. As will get older and software program will get newer, it’s inevitable. However there’s another excuse your iPhone could be gradual: the battery.

This phenomenon was first proposed in a Reddit thread, after which subsequently in a weblog publish by John Poole at Geekbench. Now, Apple has confirmed that it slows down iPhones with growing older batteries. Right here’s why it occurs, and what you are able to do about it.

Apple Throttles Efficiency as Battery Well being Decreases

As your battery will get older, its well being degrades. Over time, the battery is ready to maintain much less and fewer of a cost—so a battery that lasted 12 hours when it was new would possibly solely final eight after just a few years below the similar circumstances. That is regular, and it occurs on each gadget you personal with a lithium-ion battery: telephones, laptops, tablets, and even different devices like sensible watches.

There are some issues you are able to do to extend a battery’s well being (like avoiding full discharges, and holding it away from warmth and chilly), nevertheless it occurs to each battery finally.

The issue, Apple found, is that the previous few generations of iPhone skilled crashes when this occurred. As a substitute of simply having decrease battery life, the cellphone would additionally shut down unexpectedly each time the cellphone tried to tug extra juice than the battery may provide.

Their “repair” was to decelerate your cellphone’s processor as soon as the battery well being degrades to a sure level. In an announcement to TechCrunch, Apple stated:

Our objective is to ship the finest expertise for purchasers, which incorporates general efficiency and prolonging the lifetime of their gadgets. Lithium-ion batteries grow to be much less able to supplying peak present calls for when in chilly circumstances, have a low battery cost or as they age over time, which may end up in the gadget unexpectedly shutting down to guard its digital parts. 

Final yr we launched a characteristic for iPhone 6, iPhone 6s and iPhone SE to easy out the instantaneous peaks solely when wanted to stop the gadget from unexpectedly shutting down throughout these circumstances. We’ve now prolonged that characteristic to iPhone 7 with iOS 11.2, and plan so as to add help for different merchandise in the future.

In different phrases: as soon as your cellphone’s battery is shot, your processor will decelerate, too. That is by design.

The right way to See If Your Cellphone Is Affected

To see in case your cellphone is affected by this phenomenon, you may obtain a 99 cent app in your cellphone referred to as Geekbench. Begin the app, select the “CPU” possibility, after which faucet the “Run Benchmark” hyperlink.

 

You’ll get a outcomes display like this:

This iPhone 6 has undoubtedly been throttled because of its battery.

Listed here are the best scores for the affected telephones:

  • iPhone 6 and 6 Plus: 1620
  • iPhone 6s, 6s Plus, and SE: 2500
  • iPhone 7: 3500

In case your rating is considerably decrease than that—as in, a whole lot of factors decrease—then your cellphone might be throttling its CPU resulting from battery well being. That is very seemingly in case your cellphone is greater than two years outdated or so. (Notice: It’s unclear if the “Plus” fashions are affected by this, as Apple’s assertion is obscure, however working the CPU benchmark ought to let . Fashions sooner than the iPhone 6 shouldn’t be affected.)

Replacing the Battery Will Give Your Cellphone New Life (in Extra Methods Than One)

In case your cellphone is certainly slowing down because of poor battery well being, changing the battery will give your cellphone new life. Not solely will you get a longer-lasting battery by changing an outdated one, however your cellphone ought to soar again as much as its prime pace. It received’t essentially be as quick as the day you bought it (keep in mind, new software program will nonetheless gradual it down finally), nevertheless it ought to final you a bit longer.

Replacing your battery is straightforward: simply take it to the Apple Retailer and ask them. It prices you $80 for a alternative (until you could have AppleCare+, by which case it’s free so long as your battery is beneath 80% of its authentic capability). You may have it performed for much less from a smaller third-party store (or by doing it your self), however we advocate going with Apple for finest outcomes—they received’t cowl any errors you or your neighborhood store make.

“However $80? Screw that!” I can already hear a few of you say. Hear me out: if the different is shopping for a brand new cellphone, $80 isn’t a foul value.

Consider it this fashion: you paid $650 (at the very least) for that cellphone when it was new. If it lasts three years earlier than battery life and efficiency undergo to the level of being irritating, meaning you paid about $215 per yr of strong iPhone utilization. A battery alternative received’t make that cellphone final endlessly, however even when it extends that cellphone’s usability by one yr, $80 isn’t a foul value to pay.


Now, there’s much more lets say on the topic—is Apple doing a foul factor right here?—nevertheless it’d be largely hypothesis. A lot of persons are claiming that is “deliberate obsolescence” in motion (in case your cellphone is gradual, most individuals assume they should purchase a brand new cellphone—not exchange the battery). However Apple argues that that is essential to hold the cellphone working previous a sure level, since with out the CPU throttling, telephones would begin shutting down randomly after a pair years. We’re skeptical of Apple’s reasoning, however we will say one factor for sure: Apple’s communication was horrible on this subject, and so they deserve criticism for the way they saved their customers in the darkish for nearly a whole yr.

Whether or not you give Apple the good thing about the doubt or not, although, that is the actuality iPhone customers are caught with for now. So in case your cellphone is just a few years outdated and is feeling just a little gradual, a brand new battery can go a great distance—even whether it is $80.
