How to save battery on iPhone SE (2020), any iPhone

While you may not have access to a lot of behind-the-curtain controls, Low Power Mode certainly does. It will shorten your auto sleep time, reduce the frequency of notification retrieves, reduce the screen’s brightness by just a bit, and even throttle the processor so it doesn’t drain as much energy. This will, in turn, save iPhone battery.

The iPhone will prompt you to enable Low Power Mode when its battery hits 20%. But you can do it manually at the start of the day, even when it’s still at 100%. Do that if you are planning to have a long, long day and need every percent you can keep.

Still, Low Power Mode is kind of the “bringing a sledgehammer to a knife fight” solution. There are a lot of granular options you can tweak yourself to save iPhone battery before resorting to throttling your phone or lowering its auto sleep to the unusable 30 seconds. Let’s explore them!

What is Background App Refresh?

Background App Refresh is a slightly misunderstood feature. See, unlike Android — which is no enemy of letting apps just run active in the background — iOS is much more prone to “freeze” or “suspend” apps when they are not on screen. Essentially, iOS remembers where you left off and disables the app. The next time you open it up, iOS recalls the “frozen” data and loads it up, so it kind of looks like the app has been running in the background all this time.

Now, some things may have changed since the last time you were in the app. If it's a social feed — new posts may have appeared. If it's a cloud app, like Google Keep, you may have new notes which you created on a different device.

This is where Background App Refresh comes in handy. iOS will periodically scan for new data for each app, load it up, and add it to the “frozen” data. So, when you go to open said app back up, you will not only see the screen where you left off, but the new information will also appear in an instant.

So, it’s actually a useful and intelligent way of updating app information and there is very little benefit to all-out disabling it.

However, what I do suggest doing is that you go into Settings -> General -> Background App Refresh and setting it to only update when you are on Wi-Fi.

My reasoning is simple. For one, Wi-Fi drains less battery than cellular, and secondly — if you are on Wi-Fi, this means that your phone is probably near a wall outlet or wireless charger. So it’s safe from battery drain. Once you go out and about and the phone is on the LTE network, it won’t try to refresh apps in the background, which should extend your battery life a little bit.

Identify Location hogs

It’s a well-known fact that location pinpointing can take its toll on a phone’s battery. If you don’t intend to use any apps that need location tagging for one reason or another, just go into Settings -> Privacy -> Location Services and turn the toggle at the top off.


This will disable the iPhone's GPS and any form of location-based tracking until you turn it back on.

If you don’t want to go with the “nuke it all” method, the Location Services menu gives you quite a lot of control over what app — and when — can use your phone’s location. You can identify which apps may be potential battery drainers by looking for an arrow next to their names.


What do the arrows in Location Services mean? A black arrow means the app has gotten your location some time in the past 24 hours. A purple arrow means that an app has used Location Services very recently. If you come to this menu often and notice that a certain app always has a purple arrow, maybe it’s time to take this puppy’s access away. A hollow arrow means that the app can access location only when something specific happens — time of day change, some kind of emergency, if the phone detects that you’ve left / entered an area, et cetera.


When it comes to permitting apps to use location, you’ve got quite the pick. You can allow an app to always have access to location data — this is useful for navigation apps, so that it can keep giving you directions even when the app is minimized or the phone is sleeping. For any other apps, I suggest selecting “While using app” or “Never”, depending on need and use case.

Location Services - System Services

At the bottom of the Location Services menu, you will find System Services. Now, these are a part of the core Apple experience, are light on the battery, and most of them are there to improve your experience. Still, you can disable some of them on your use case.

Apple Pay Merchant ID can stay on. You need it if you use Apple Pay and if you don’t — it will never fire off in the first place. Things like compass calibration, SOS, and Find my iPhone are — of course — essential. HomeKit you can turn off — unless you have a smarthome hub with HomeKit appliances set up, of course.


I generally recommend keeping Mobile Network Search and Networking & Wireless on. Basically, the phone will remember which connections work where, so it will very quickly and easily find cell signal or Wi-Fi. Presumably, it drains less battery that way instead of forcing the phone to constantly scan for signals as you move about.

Then you have toggles like Popular Near Me and Routing & Traffic, which I keep off because I use Google Maps anyway.

Silence pesky notifications or just disable screen light-up

If you ever needed a better reason to go into Settings and mute all the pesky apps that keep lighting your screen for no reason, this is it — every time they pop up, your screen lights up, the phone may or may not vibrate and produce a sound. Again, this can add up to unnecessary battery drain over time. And really, Reddit, I don't need you to tell me what's trending on a subreddit that I am not even following.

Go into Settings -> notifications and disable the apps you don't care for. Alternatively, if you want to hear a beep when a new message arrives, but don't want your screen to light up for every little message, disable the Lock Screen option on your chat apps.

By doing this, you will still hear a notification sound whenever you get a new notification, but its message will not show up on your lock screen, ergo the screen won't light up for every new spam email. Admittedly, this may take some time if you already have a few dozen apps on your iPhone. So hey, take it up as a favorite past-time.

In the spirit of not lighting the screen for no reason, you may want to get rid of Raise to Wake. It will light up the display every time you tilt the phone upwards — even if it's in a pocket or purse, if it has a wallet case on or not.

Don't worry, you can still wake the screen by just tapping on it once (or pressing the home button on iPhone SE).

It's super-cool that you can call up Siri at any point by just saying her name. What's not cool is that the phone needs to constantly be listening and looking for the "Hey, Siri" phrase... As good as Apple is at optimizing its hardware, this will still add a toll on your battery life.

You can still call up Siri by just holding the right-hand button on your iPhone (your home button on the iPhone SE).

Using Google Photos?

Are you making use of Google Photos' unlimited free storage to back up all your photos? That's cool, but make sure you are not using mobile data to upload photos and videos. My logic here is similar as before: for one, mobile data drains more power, secondly, being on Wi-Fi probably also means you are near a power outlet.

Account sync settings: fetch, push, manual

Another minor change you may wish to consider is to setup how the iPhone gets notifications for your accounts — mail, contacts, calendar, notes, and app settings. There are three tiers of notifications. Here's the difference between push, fetch, and manual:

• Push - the new information becomes available on your iPhone as soon as possible
• Fetch - the iPhone actively scans for new information once every x amount of minutes
• Manual - the iPhone only looks for new information when an app that uses it is opened

Naturally, push drains the most battery as it keeps the phone "listening" constantly. Fetch is a good compromise, as you can set it to 60-minute intervals. And manual is the "save the most power" option as it will only download new items when the respective app is open.

This also helps save a little bit of battery. But hey, every little bit helps, right?

Bluetooth is used for wireless connections and data transfer over AirDrop. Do you need it to be listening all the time? Probably not. Especially if you don't even own wireless earbuds.


Here's the thing — turning it off from Control Center (the pull-down menu from the top-right; swipe up on iPhone SE) will only disable it for 24 hours. To actually turn Bluetooth off, you need to go into Settings -> Bluetooth and flick its toggle off. That should save some battery in the long run.

Use wired headphones

Yes, Apple removed the headphone jack and is selling you a nice pair of wireless AirPods, which are pretty good earphones that offer seamless connectivity and autoplay features. But streaming audio over Bluetooth does take a bigger toll on the battery over just using a wired connection.

So, it’s back to cavemen times for us. Either use the EarPods or any licensed earphones with a Lightning connector or grab yourself a Lightning-to-headphone dongle and use any headset you like.

So, you're in a hike, trekking in and out of cell tower coverage. Or, you're on the road and your signal keeps dropping on the highway. You know you probably can't take a call or receive notifications consistently. But your iPhone doesn't — it'll keep scanning and trying its hardest to find stable signal. This takes a pretty large chunk from the battery. Just bring down the Control Center from the top right (on iPhone SE, it's a swipe up gesture) and tap on the airplane icon to give your iPhone a break.


Do make sure you've downloaded your route beforehand, if you're using navigation.

Once you've stopped and are set up in a location, disable Airplane Mode to look for a signal.

If all else fails and you need your iPhone to last longer than it does — get a battery case for it. They don't look pretty and they certainly add a lot of bulk. But one of these puppies will make sure your iPhone won't run out of battery when on a roadtrip.
