Turn off Battery-Intensive Features
By default, the iPhone offers features that rapidly consume battery power. Content refreshes and automatic app updates can drain the battery even when you are not using your iPhone. Features like auto-brightness can sometimes use more power than they save. If your iPhone can deliver 300-500 full charge cycles, these background features will diminish battery lifespan over time. They can also slow your iPhone. For more information on turning off unnecessary features and speeding up your iPhone, please read this article.
Don’t Drop or Shock Your iPhone
Mobile computing devices go with us just about everywhere. Unlike a desktop computer, this makes them more susceptible to drops and shocks. Such trauma can damage lithium-ion batteries, diminishing their capacity or lifespan. In fact, a damaged lithium-ion battery could pose a fire risk.
If you have dropped your iPhone and noticed diminished battery performance and capacity, I recommend having it replaced immediately. Given the possible fire hazard, this is not a suggestion to take lightly.
Although I recommend not using a case, if you are prone to dropping things, protecting your iPhone makes sense. Find a case that can protect your iPhone, but don’t let it give you a false sense of security. Even with a case, dropping your iPhone could damage the battery and increase the risk of fire.
Just about every article I have written about iPhone batteries has been met with skepticism. I am often challenged with information from other sites with no science or research behind them. I encourage comments and challenges, but prefer when they originate from fact. It’s remarkable how controversial and superstitious iPhone battery maintenance can be.
People get upset when their 1 year old iPhone can’t hold a charge. It’s expensive to replace the battery, and some people may just opt for a new iPhone. Apple has been notoriously quiet on the finer points of iPhone battery maintenance, which creates problems for writers like me. Some of my suggestions are assumed to be mythical, because Apple is silent on the matter, or recommends a practice that isn’t optimal.
Skepticism is beneficial to a certain extent. It’s all too often that the counter argument comes from a website with no facts but some spiffy design and a modicum of popularity. A lot of websites try to be controversial in order to attract readers. It’s like a poorly behaved dog. It wants attention regardless of whether it’s good or bad.
For these reasons, I provide the sources for this article. Feel free to read them and look at the data on battery lifespan based on several factors. The science doesn’t always agree. Apple may make a claim that Battery University or Electropaedia don’t support. Keep in mind that some sources apply to lithium-ion batteries in general and not the iPhone. Apple’s recommendations ensure a reasonable lifespan for your iPhone’s battery. They strike a balance between convenience and longevity. It doesn’t mean that Apple’s suggestions are optimal.
You also have to find the right balance between convenience and optimal battery life. Even though it’s optimal to charge the iPhone to 58%, I wouldn’t do that myself. Long battery life is one of the iPhone’s best features. For further reading, here’s the science behind this article:
