A brand-new iPhone can easily last all day, but that wanes over time as parts age. But newer software takes its toll too, as the latest iOS 18 software and apps, including Apple Intelligence AI, can drain them quickly. Shooting photos and videos, playing games and watching shows and movies can deplete the battery, too. But before you consider buying a new Apple phone, like the new iPhone 16 or the more affordable iPhone 16E, give these battery hacks a try to make your long-lived iPhone a bit more daytime before needing to recharge it.

Some of the causes of battery drain are easy to control, like features turned on by default that can be switched off. Others might require a lifestyle change as you switch up how you use your iPhone throughout the day, breaking habits and going without some minor perks. In all cases, it’s helpful to keep a pocketable power bank in your pocket or bag just in case. 

Here are eight tips for diagnosing and extending your iPhone’s battery life.

1. Find what’s draining your battery

Some apps drain more of your iPhone’s battery than others, and it’s no surprise that the biggest offenders are those that track location, stream video or generate graphics (games, for example, especially fast-paced online ones). If it makes your phone heat up a bit, it’s probably running down your battery faster than casual use. 

There’s a way to specifically check which apps are draining your battery the most. Head to Settings > Battery and scroll down to see which apps are the worst culprits for taking the biggest percentage of your screen time. Also, don’t skip the Insights and Suggestions section, as it does all the analysis for you and shows you which apps and settings to change.

Note that these are the biggest uses of your battery, but you’ll have to parse through them to see which are big battery drainers, like YouTube or TikTok. In my case, Safari takes the biggest chunk of my use, which represents a lot of endless scrolling of sites and forums — but YouTube is in second.

2. Drop the battery-draining apps

Let’s face it — whether it’s Instagram, TikTok or something else, one or two apps are probably draining an outsized chunk of your battery every day. If you want longer battery life, remove the app by long-pressing its icon on the Home Screen and clicking the «x» in the corner. 

Yes, you could try to limit your use before wiping these apps from your phone. If you believe in your willpower, you could just stick the offending app in a folder to keep it out of sight, out of mind. 

But if you need some help from your iPhone itself, you can set a time limit for individual apps or whole categories. Go to Settings > Screen Time and tap App Limits. From there tap the Add Limit button to select by entire categories or specific apps. 

3: Turn down your screen brightness

You can save battery by turning down your iPhone screen’s brightness. This one’s pretty easy: tap-and-drag from the top-right corner to bring up the Control Panel and manually lower the brightness bar. Alternatively, you can find these controls in Settings > Display & Brightness or if you prefer to be verbose, you can ask Siri to reduce the brightness.

While you’re in the Display & Brightness sub-menu, tap Auto-Lock to set your phone to have a shorter time before locking itself. That way you won’t be draining battery if you put your phone down and paying attention to something else.

4: Turn on Low Power Mode 

Whenever you dip below 20% battery, your iPhone will ask if you want to extend your remaining battery life by turning on Low Power Mode. But you can also manually activate it at any time, either by opening up the Control Panel (if a shortcut has been set there) or by going to Settings > Battery and switching it on there.

Low Power Mode is a catch-all setting that ekes out more battery life by reducing drain from several active and passive sources. It dials down background activity like downloads and mail fetching, lowers the screen brightness; as well as turns off the Always On Display. 

5: If your 5G signal is bad, switch to 4G LTE

While carriers have built out their 5G networks over the years, some phone owners will struggle to get a strong signal in areas with poor coverage — or in places 5G struggles to reach, like within buildings and underground. Your iPhone burns a lot of battery trying to stay connected, so if you don’t have a great connection, it might be best to manually revert to 4G LTE.

To do so, head to Settings > Cellular, then tap on Cellular Data Options. If you don’t see Cellular Data Options, select the SIM or eSIM that you’re currently using. On the next screen, tap Voice & Data and select LTE. You’ll only use 4G LTE to connect to mobile networks, which should be more widely available among carriers.

You should also be aware that downloading data drains battery, too, so manually restricting that could extend your battery life. To do so, head to Settings > Cellular, then tap on Cellular Data Options. If you don’t see Cellular Data Options, tap on the SIM or eSIM that you’re currently using. On the next screen, tap Data Mode then tap Low Data Mode, which will pause automatic updates and background tasks.

6: Selectively disable location services

Tracking your location drains battery, so turning it off when possible is a good idea if you don’t need it. Triangulating your position actually takes multiple sensors, so it’s not an insignificant amount of battery saved — your iPhone uses GPS, Bluetooth, and crowdsourced Wi-Fi to narrow down where you are. 

To see which apps track your location, tap Settings > Privacy & Security > Location Services and tap through to tweak each individually. But you can also turn off Location Services entirely with the toggle at the top of the screen.

It’s worth nothing that Location Services are required for Apple’s Find My feature, so if you want to track down another object linked to your account, you’ll need Location Services turned on. Likewise, you’ll need it turned on if you ever lose the iPhone you’re using, so make sure to reactivate it later. 

7: Turn off Always On Display

Introduced in the iPhone 14 Pro series in 2023 and only available on the newest Pro and Pro Max models, Always On Display does what it says: It keeps a dimmed version of your lock screen on. This allows you to check the time, on-screen widgets and how many notifications you have without needing to fully unlock your phone. But it also saps your battery by having that low-light version of your display constantly activated.

If you can live without having that quick info at a glance, go to Settings > Display & Brightness > Always On Display and turn it off. It may not be a huge power saver, but it’s one of the features on the newer iPhone Pro models that seemingly counteracts any battery increase Apple ekes out of the phones. Under the Always On Display settings, you can also disable the Wallpaper and Notifications for a more minimal version that only shows the date and time against a black background.

8: Install a new battery

Over years of use, your iPhone’s battery will degrade and it simply won’t be able to hold as much juice as it could when brand-new. Thankfully Apple has made it easy to check how your battery is doing — just go to Settings > Battery > Battery Health and you’ll get an easy diagnosis, an estimate of its maximum capacity on a full charge and how many full recharge cycles it’s gone through. 

Apple generally recommends replacing your battery when it dips below 80% maximum capacity. Keep in mind that it’s not just the maximum battery life that might suffer if you don’t swap out for a new battery — the quality might degrade so much that the battery itself could swell and warp enough to damage sensors and internal parts of the iPhone — which is rare.

Apple offers in-store battery replacement for $99 for the newest iPhone 15 models, which drops down to a minimum of $69 for the oldest iPhone SE and iPhone 5 models the company still supports. Third-party phone repair shops may offer their own rates for replacing batteries, and iFixit has a guide if you want to boldly order a new battery and attempt the swap yourself — just keep in mind that it may violate any AppleCare agreement if you go outside Apple’s repair ecosystem. 

If you’re buying the new iPhone 16E to replace your old iPhone, don’t just transfer data and sell your old device — you need to clear out all the personal data first. It’s important to know how  to reset your Apple phone, whether you’re selling your old device or making it a hand-me-down for a relative, you need to make sure it’s wiped clean before you hand it off to a new owner. Here’s how to factory reset your iPhone.

No matter the reason you want to wipe your iPhone clean, it all boils down to making sure that all your personal data is gone. This can be sensitive and personal information, like family photos you definitely don’t want to hand off to a stranger. It also includes the litany of private details that your iPhone stores, from credit card information to contacts to everything in your apps. 

Thankfully, it’s easy to factory reset your iPhone, although you’ll be asked several times to make sure you’re ready to clear it completely. You’ll also want to prepare before wiping your phone. Here’s how to do it.

Don’t go further without backing up your iPhone

The first step is to make sure all the data you want to keep is safely backed up. This can easily be done over iCloud, although you can also make a manual backup. 

The same way you’d want to back up your iPhone before updating to iOS 18, head to Settings > [your name] > iCloud > iCloud Backup and tap Back Up Now. This should take a little while, but you’ll be able to restore from this online backup if you need to. 

You can also manually create a backup by connecting your iPhone to your computer, although the process differs between PC and Mac. You can still download iTunes to your Windows PC, through which you’ll sync your iPhone and create a backup through that software. With the end of iTunes on Mac in 2019, you’ll have to go through Finder to manage your iPhone, but otherwise, the process of backing up is relatively straightforward. 

Note that iPhones are good at moving data wirelessly from one device to another in close proximity, making it easy to seamlessly transfer from your old device to a new one. After waking up your new iPhone, follow the on-screen instructions on your new iPhone to use its camera to scan your old device and let the process continue. It’s still smart to save a backup when you’re getting rid of your old iPhone.

Digitally sign out of every account you can

This is the most tedious step but a necessary part of the process, but it’s important to sign out of apps and services you’ve logged into. You should prioritize apps with more sensitive data, but it’s a good idea to ensure you’re fully logged out of anything with personally identifiable information.

You won’t want someone popping into email, contacts and calendar accounts, so head to Settings > Apps > Mail/Contacts/Calendar > Accounts to manually unlink those. 

Bank and payment apps, external email and messaging apps, workplace software like Slack or authentication apps and even digital community apps like Discord are good to log out of. Lastly, if you’re selling your iPhone or giving it to someone else, make sure to disable Find My before erasing your phone. Go to Settings > [your name] > Find My.

If you’re moving to a new iPhone, transfer your cell service

If you’re about to reset an older iPhone that used to be your daily driver linked to your carrier account, you’ll want to transfer service to your new iPhone before factory wiping your device. Why? Because you’ll probably use your older iPhone to call your carrier to switch that service over. Don’t get stuck without a phone like I did.

You used to be able to yank your SIM card out of your old phone and stick it in the new one to carry service over. Not so much these days, as the iPhone 14 and later models sold in the US don’t come with a physical SIM card — it’s eSIM all the way. You’ll need to call your carrier to transfer your data plan over to your new iPhone, but it’s a pretty effortless process. If worse comes to worst (like if you’ve already wiped your old iPhone), you can bring your new iPhone into any of your carrier’s retail stores and they can digitally transfer service over to it.

If you’re just clearing out an old iPhone or will still use this one after resetting it, proceed to the next step. 

Finally, here’s how to factory reset your iPhone

If you’ve done the above and are ready to reset your iPhone, open up the Settings app. Then tap General > Transfer or Reset iPhone > Erase All Content and Settings and confirm. You’ll be asked to enter your iPhone’s PIN code, then enter your Apple ID password (to unlink the device from your account and turn off Find My capability if you haven’t already). 

Once you’ve done that, the screen will turn black and you’ll get a black progress bar at the bottom (similar to if you were updating to a new version of iOS). In a few minutes, the word «Hello» will appear on the screen in different languages, just like it did the first time you activated your iPhone. Congratulations, it’s been successfully reset.

That done, you’re now free to hand it off or send it on its way to a new owner. 

I drop into a fantasy land with a sword and two squadmates, all dedicated to defeating the Nightlord ruling over our shadowy limbo realm — but first, we have to survive. From the deepest mines to the highest snow-capped peaks, we clashed and slew monstrous beasts for two in-game days at a breakneck pace to stay ahead of the closing ring of blue flame. On the third day, confronting the Nightlord in its lair, we get close to defeating it with wild weapons and spells — but win or lose, we shrug and queue up to drop once more.

This is Elden Ring Nightreign, a spin-off of studio FromSoftware’s phenomenally successful and notoriously difficult fantasy action-RPG game Elden Ring. Rather than spend dozens of hours exploring wide lands in a solo adventure, Nightreign takes the combat and boss structure to a co-op multiplayer setting where tight gameplay must be balanced against speed and strategy to survive each trip into the game’s arena. 

Nightreign is a departure for FromSoftware, eschewing the slow solo explorations of its previous games in favor of fast-paced rounds building your heroes from scratch, kind of similar to battle royale shooters like Fortnite and Apex Legends. But unlike those PvP-intensive games, each Nightreign round pits the friendly squad against a map full of computer-controlled enemies, leaving players dependent on teammates to survive — or themselves, if they’re bold enough for a solo run. (Currently, players can either go it alone or queue for three-player squads.)

Nightreign is focused, repeatable Soulslike action 

Nightreign ambitiously tries to see how much of an idiosyncratic yet popular game can be slimmed down and imported into a new gameplay loop. It’s easy to put a hundred hours or more into Elden Ring, exploring every nook and cranny, upgrading weapons and trying out different strategies. Nightreign punishes that slow pace, requiring squads to blitz around the map, hitting specific points of interest to get as strong as they can to survive and defeat the big boss at the end of each three-day run. (Playing through three in-game days and facing the Nightlord boss at the end of a run can take 45 minutes to an hour — or less, if you die along the way.)

This approach will be catnip for fans of FromSoftware’s signature tough boss combat, as it distills Elden Ring down to its core combat loop with just enough randomized surprises to somewhat refresh each run while keeping enough the same to quickly plan and alter course along a run. That makes sense, as Nightreign is directed by Junya Ishizaki, the person in charge of overseeing the combat for Elden Ring. 

On the surface, a lot has carried over from Elden Ring, but there are plenty of subtle refinements to make it fit fast-paced multiplayer gameplay. Player characters kit themselves out with powerful weapons and spells without worrying about stat requirements or armor. There’s no fall damage, allowing players to drop from great heights to keep moving, and spirit hawks lift them in aerial routes around the map. Running up to a spiritual spring of blue fire lets you leap upward hundreds of feet in an invigorating ascent with a heavy bass sound effect — I breeze around the map feeling fast and powerful, a hunter in a forsaken land.

But there is some part of FromSoftware’s spirit that’s lost in Nightreign: that feeling of being dwarfed by an alien world that slowly unfolds its mysterious history as you cut your way through its cursed remains. Instead, Nightreign leans heavily on the mystique and lore built up in Elden Ring, presenting a mirror version of that well-known setting with its own limited mythology that can be revealed with optional missions. But you can just stick with the gameplay loop, and many will, turning Nightreign into a greatest hits album of fun FromSoftware moments that doesn’t introduce too much that’s new — beyond designing the game around persistent squad multiplayer.

And the multiplayer is a joy, despite rough edges that, in true FromSoftware fashion, are unexplained or buggy in ways that the community will likely fondly rehabilitate as part of the game’s charm. For instance, the game requires a lot of ascending big plateaus by hopping up misshapen steps with erratically successful ledge grabs. It’s minorly frustrating, but does ratchet up the tension when you’re trying to escape death or rush to a teammate’s aid — and much like the rest of FromSoftware’s games, Nightreign is so tightly polished elsewhere that this slight jank, or other aspects like it, is tolerated and treated as part of its difficulty and flavor.

Which is all to say that, for $40, Nightreign delivers on its vision of concentrated, easily repeatable FromSoftware action that’s sure to hook the studio’s die-hard fans and potentially lure other difficulty junkies who prefer quick multiplayer romps to lore-heavy solo adventures. With rogue-like novelty that rewards replaying, there’s a decent blend of familiar elements and shifting map factors for fans of FromSoftware’s tough gameplay to get their fix without needing to replay games they know so well.

Fans of the longevity of Elden Ring and its DLC Shadows of the Erdtree should be cautioned: On top of a more narrow appeal than prior FromSoftware games, players will vary in how much replay value they’ll get out of Nightreign, since there’s currently only one map and a finite number of end-run bosses to tackle. The eight character classes, called Nightfarers, have varying complexity in their ability mechanics and will take players a while to master, but they’ll likely spend most of their time attacking with weapons and dodging enemy blows, as in Elden Ring.

There are plenty of randomized factors that mix up a run, from shifting terrain opening up new areas to «invasions» of powerful enemy computer-controlled Nightfarers. But in the 20 hours it took me to beat half the end-run bosses and kill the final boss, the single map became such a known entity that I stopped paying attention to it as anything but a race course to speed over on the way to my next task.

Where Elden Ring Nightreign triumphs and falters

As a FromSoftware fan who can muck his way through its games in ways that nobody would describe as «dominant,» Nightreign is something of a relief, as my two permanent teammates can help a lot in distracting bosses and picking me up when I make mistakes. 

Thanks to previewing the game earlier this year, I hit the ground running, pairing up with CNET teammates to try taking on big bosses — and failing. But after pairing up with a very skilled Bandai Namco employee (one of many who volunteered to help reviewers like me take on bosses and finish the game), we took down some of the biggest and baddest Nightreign has to offer. 

There’s no mistaking that I was carried by more skilled teammates, and that has me concerned for a bit of the game’s flow and player skill growth. While I was used to cautiously and slowly going through FromSoftware games, my more skilled teammates flung us outbound on a speedy tour of the map zones we needed to hit to get as strong as we could. When I fell, they tanked bosses and dodged attacks to revive me. When the map’s Shifting Earth conditions led to a new area, my expert teammate took us to the exact right spot to take full advantage of it — something that might have taken plenty more runs to figure out on my own.

I certainly improved over time, but it was all during rounds — in the Roundtable hub, players return to between missions, a Sparring Grounds area lets you try out each of the eight total (six starting, two unlockable) Nightfarers’ regular and ultimate skills, along with every weapon in the game. But it’s a far cry from the game’s high-pressure situations of boss events, enemy groups and more. Players will improve only by trial and error in the field, sometimes letting down their teammates in the process.

Yet, when you and your team are firing on all cylinders, there’s no thrill like eking out a win over a monstrous boss. After killing a trio of end-run bosses, another reviewer, Bandai Namco employee Micah (team Cat Password all the way) and I locked in to beat the game’s final boss. Shouting out congratulations over team chat, my body shaking with adrenaline, I felt like I’d completed a gaming feat — something not unknown to many Elden Ring players after surmounting one of that game’s many challenging bosses. 

I felt accomplished. I wanted to tell everyone, and when the game comes out, bring my friends in to play Nightreign with them, guiding as I was guided. But would I recommend my FromSoftware newcomer friends to play?

Who is Elden Ring Nightreign for?

The more I thought about it, the more I felt my dozens of hours in Elden Ring were essential to starting Nightreign strong — and even then, it took 20 hours in Nightreign to feel like I’d gotten a good handle on the best way to play. Knowing Elden Ring’s massive arsenal of weapons and spells felt essential to picking up Nightreign and immediately having fun.

New players who don’t have baked-in knowledge of Elden Ring or the combat flow of FromSoftware games will probably be left in the cold. Aside from a tutorial section teaching players basic mechanics, Nightreign lacks the carefully crafted early sections of the studio’s other games — it quite literally drops players into the map for a run and tells them to get killing. 

The virtue of FromSoftware’s single-player adventures’ difficulties is that players could approach them at their own pace; in Nightreign, they must rapidly adapt to the studio’s particular flavor of tough combat while also figuring out a largely unexplained world. The studio’s famed minimalist storytelling will likely do a disservice to new players who die too quickly to learn.

Whether they continue with the game after a humiliating defeat is, indeed, the classic trial that every FromSoftware player faces. But it sure seems like new players have a high hill to climb picking up on the game’s subtly conveyed details — map flow, enemy camps, bosses, weapons, churches, strategies — while also figuring out how to play Soulslikes from scratch. 

And yet, Nightreign is so unlike every other game out there that its sheer novelty may be enough to tempt FromSoftware veterans and newcomers alike. It’s polished, is easy to get into the action and has a very high skill ceiling. If players stick through its lack of direction and difficulty, they’ll find a multiplayer game that feels rewarding to win in a way few other games are. And when they lose, they may find themselves like I did — nursing annoyance that they fumbled but eager to drop in one more time with their trusted squad.

Elden Ring Nightreign launches on May 30 for PC, PS5, PS4, Xbox Series X/S and Xbox One consoles for $40. Owning the original Elden Ring is not required to play this game.
