Keeping My iPhone 6 Alive Without Replacing the Battery

Published: 2018-08-14 • Last updated: 2021-05-03

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.

Umm, check.

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.

# Make UI events less resource intensive

Disabling it from Control Center will only disable it temporarily. Disable it from Settings to make it stick.

# Free up storage

Delete unused apps. Then install Google Photos, and once your photos are done backing up, delete them locally.
