Are you happy with your iPhone’s battery life? If your iPhone regularly ends up in Low Power Mode or doesn’t always make it to the end of the day without extra juice, read on to learn how to determine when it’s time for a new battery.
It’s important to schedule your battery replacement before the end of the year as Apple has indicated the price will be going up January 1, 2019. You can have your battery replaced at TBI Computer for $39 until December 31, 2018. After that the price will rise depending on the model of your iPhone.
Here are the top three signs that you need a new battery right away.
1. Your iPhone Is Bulging
This one is obvious and possibly dangerous. If the lithium-ion battery in your iPhone is defective or damaged, it can swell due to outgassing or other chemical reactions. In the worst case, a swollen battery can catch fire or explode—it’s why airlines are concerned about batteries in luggage.
If you notice your iPhone is swelling, you need to deal with it immediately. Power it off and place it in a fireproof container. Then take it to TBI Computer or an Apple store right away, or call us for advice on how best to proceed.
2. Your Older iPhone Has Lousy Battery Life or Shuts Down Unexpectedly
Generally speaking, iPhone batteries last a few years without losing too much capacity. However, if your iPhone’s battery drains well before the end of the day, or if it shuts off unexpectedly, that’s a sign that you may need to replace the battery.
Before you do that, go to Settings > Battery and look at battery usage by app, which shows which apps have consumed the most power for the last 24 hours or the last 10 days. Tap Show Activity to see how many minutes the app was in use.
If anything near the top of that list seems odd—it’s not an app you use much or its background activity is excessive—consider force-quitting the app. (Open the app switcher by double-pressing the Home button on a Touch ID iPhone or swiping up and slightly right on a Face ID iPhone, then swipe up on the app’s thumbnail.) You might also disable that app’s switch in Settings > General > Background App Refresh.
But if your iPhone is more than a few years old, it’s probably time for a new battery. Batteries are consumable items, and Apple designs the iPhone to retain up to 80% of its original capacity after 500 complete charge cycles (from 0% to 100%, even if that comes over the course of several charging sessions). Don’t suffer with a weak battery—just get it replaced.
