Keeping My iPhone 6 Alive Without Replacing the Battery
Updated: May 3, 2021
If you have an older generation iPhone, you’ve likely felt the effects of a lithium-ion battery nearing the end of its lifespan. If you’ve update to iOS 11.3 or higher, apple enables “performance management”.
According to a support article, in cases that require more extreme forms of performance management (i.e. my iPhone), the user may notice: longer app launch times, lower frame rates while scrolling, backlight dimming, lower speaker volume, gradual frame rate reductions in some apps, and/or apps refreshing in background may require reloading upon launch.
Per another support article, your iPhone battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles. Well I’ve had mine since 2015, so 3 years of charging, at 1 charge per day, brings me to 1,095+ charges. Yep, it’s barely hanging in there.
Because I’m stubborn, I’m doing what I can to prolong the battery life without actually replacing the battery. Eventually I’ll have to give in and visit an apple store, but until then, here’s what’s helped.
