Whether youve got an older iPhone with a worn-down battery or have a newer
one that isnt lasting as long as youd hope, there are a number of ways to
improve battery performance. Follow along for a look at 7 tips and tricks to
extend iPhone battery life.
Going through the settings below can meaningfully extend your battery life
on the spot, but the result will be dependent on what youre willing to
trade for improved efficiency.
If you find youd rather not change many (or any) of the settings, another
option is to just pick up a battery case or portable power bank or look into
replacing your battery or upgrading your iPhone.
One more consideration: While wireless charging is convenient with modern
iPhones, wired charging juices them up much faster, up to 50% in 30 minutes.
How to extend iPhone battery life
1. How are apps using your iPhone battery?
Head to Settings > Battery to check out the details of your battery usage.
Last 24 Hours is the default and shows which apps are using the most
energy (including Home & Lock Screen and Siri).
Tapping the Last 10 Days toggle on the right-hand side gives you a broader
look at whats been eating up your power.
Also, take a look at battery life suggestions just above battery usage (near
the top). This will give you quick, actionable ways to reduce battery drain.
2. Low Power Mode and Performance Management
Low Power Mode is a quick way to extend your battery life when needed. The
feature works by suspending mail fetch, background app refresh,
auto-downloads, and more with a single button. This isnt an everyday type
of feature (hopefully), but is handy nonetheless.
You can turn on Low Power mode under Settings > Battery. However, its
useful to have quick access to Low Power Mode in Control Center. Navigate to
Settings > Control Center > Customize Controls, then tap the + icon next to
Low Power Mode if its not already there.
Another feature, sort of like an automatic low power mode, is iOS
Performance Management. Essentially if your iPhone battery has been
degraded, performance will be automatically reduced to conserve battery and
prevent it from shutting down unexpectedly.
You can check if your iPhone is using Performance Management in Settings >
Battery > Battery Health. While you can disable performance management for
iPhones with degraded batteries, keep in mind that your iPhone will eat your
battery faster without it.
Another detail: If you do disable Performance Management, you cant turn it
back on manually, youll have to wait until your iPhone unexpectedly shuts
down again, which will force it back on.
3. Auto-Lock and screen brightness
If you notice Home & Lock Screen on your battery usage is higher than
youd expect, its good to check those settings.
Auto-Lock at 30 seconds will help you preserve the most battery life.
Especially with most of Apples iPhones supporting raise to wake, 30 seconds
can be worth it.
Navigate to Settings > Display & Brightness > Auto-Lock.
Lowering your screen brightness will also help with battery life, but this
will likely come down to personal preference. You can do that in Control
Center (swipe down from the top right corner) or Settings > Display &
Brightness.
4. Hot and cold temps
Apple says that the ideal ambient temperature for iPhones and other Apple
devices is 62° to 72° F (16° to 22° C). Temps above 95° F (35° C) have the
potential to permanently damage battery capacity.
Outside of trying your best to keep your iPhone from extreme heat, its good
to remove your iPhone case if you notice it gets hot while charging.
Meanwhile, temperatures below 32° F (0 ° C) can temporarily reduce battery
life. If you live in a climate with cold temps, keeping your iPhone closer
to your body in an inside pocket can help extend battery life by keeping it
warmer.
5. Background app refresh
Low Power Mode turns off background app refresh across the board, but you
can customize which apps use this feature for a more convenient experience
as well as improved battery life. Head to Settings > General > Background
App Refresh.
You can also opt to only use background app refresh on Wi-Fi in addition to
Wi-Fi and Cellular or turn the feature off totally. However, most users will
find leaving Wi-Fi and Cellular on while customizing which apps are used for
background app refresh to be the best fit.
Turning off Background App Refresh prevents apps that youre not actively
using from updating (until you open them again).
6. Location services
Dialing in your location services settings is another way to extend battery
life. (It can reduce cellular data use too). Head to Settings > Privacy >
Location Services to update the privileges for your apps.
Look out for any apps that ask to Always use your location and switch to
While Using, Ask Next Time, or Never.
7. Push and Fetch
If you choose not to use Low Power Mode, you can manually control Push and
Fetch for your email/internet accounts.
Head to Settings > Mail > Accounts > Fetch New Data. One approach is to
leave your primary account(s) as push to receive new mail asap, and turn
less important accounts to fetch every hour or even set them to manual.
Wrap-up on how to extend iPhone battery life
In a pinch, using Low Power Mode and turning down your screen brightness are
two of the fastest ways to extend iPhone battery life. But hopefully having
a better idea of which apps are zapping your power the most and checking in
on locations services will also give you useful tools to conserve power.
And dont forget, for the best iPhone battery longevity, keep Optimized
Battery Charging turned on (and avoid leaving your iPhone at 100% charge as
much as possible). You can double-check that in Settings > Battery > Battery
Health.
