Why Older iPhones Slow Down After iOS Updates

1. Battery Throttling & Aging

Since batteries age with years of usage, iOS might slow down the device intentionally to avoid the unexpected shutdowns a practice inspired by the so-called "Batterygate" scandal. Apple currently allows users to see battery health and switch off throttling if desired OS X.

All your widgets on your lock screen make your apps run automatically in the background, continuously pulling data to refresh the data that the widgets show, such as sports scores or the weather. Since your apps are continuously running in the background because of your widgets, that means they continuously draw power.

If you're looking to preserve a bit of battery on iOS 18, the best thing to do is just skip widgets on your lock screen (and home screen). The simplest way to do this is by changing to another lock screen profile: Tap your finger onto your current lock screen and then swipe around to select one that doesn't have any widgets.

If you merely desire to take away the widgets from your current lock screen, long-press your lock screen, tap Customize, select the Lock Screen option, tap the widget box and then press the "—" button on each of the widgets to delete them.


Post‑Update Background Processing

2. Post‑Update Background Processing

Major iOS updates tend to set off a flurry of system activities such as reindexing, re‑optimizing media, or battery measurement recalibration that can cause performance to slow for hours or more. Apple now adds a notice under Battery settings with the title "Update finishing in background" to describe short-term battery/performance issues.

To set up your app to permit background tasks, turn on the background capabilities you require and then define a list of distinct identifiers for each task.

There are two types of background tasks: BGAppRefreshTask and BGProcessingTask. BGAppRefreshTask is for short-duration tasks that expect quick results, such as downloading a stock quote. BGProcessingTask is for tasks that might be time-consuming, such as downloading a large file or synchronizing data. Your app can use one or both of these.

To add the capabilities:

. Open the project editor and select the desired target.

. Click Signing & Capabilities.

Expand the Background Modes section. If the target doesn’t have a Background Modes section, click + Capability, and then select Background Modes.

If you’re using BGAppRefreshTask, select “Background fetch.”

If you’re using BGProcessingTask, select “Background processing."


Compatibility Strain on Older Devices

3. Compatibility Strain on Older Devices

New functions (i.e., high-end UI effects) tend to be optimized for new hardware. Less power-hungry models with less capable chips (A13, A14, etc.) may experience overheating, stutters, UI freezing, or app crashes when they run newer iOS releases such as iOS 26.


Why Older iPhones Lack Compatibility

Restricted Hardware:

Older devices carry slower processors and less RAM, so they cannot run demanding apps or the current versions of iOS.

Software Support:

When Apple introduces new versions of iOS, older devices eventually fall off the update list. When a device no longer receives updates, it is deprived of new features, security fixes, and improvements in app compatibility.

App Design:

Developers usually create apps for newer operating systems and hardware. This implies that newer apps will not be compatible with older phones and their previous iOS versions, which will cause bugs or even no functionality at all.

Missing Features:

New additions in subsequent iOS versions, such as interactive widgets in iOS 17, are usually hardware-specific. Older phones that are unable to update will not see these features.

How to Inspect and Resolve Compatibility Problems

1. Inspect Device Compatibility with iOS Version:

Go to Apple Support's website to determine which iOS version is supported by your iPhone model.

2. Inspect App Compatibility:

To be able to work, your iPhone must be running an iOS version that is compatible with the app's minimum requirement. If you have an older device and an older iOS version, you might be required to find an older app version that is compatible.

3. Search for Older App Versions:

There are some apps with versions that work for older iOS, which can keep your device useful for longer.

4. Be Conscious of Limitations:

Realize that if your device is no longer being updated, then it might be lacking new features and have greater security risks.

Next Update Will Be Pixel 6 & 6 Pro Last Software Update !

The news has finally been released, and for all of us who still use the phone that made Google's silicon visions a reality, it's a sad day. The following major software update will be the final one for the Google Pixel 6 and Pixel 6 Pro. The phones that started the Tensor period and brought a massive design change are running out of their warranty-supported software lifespan. For a phone that was, and honestly still is, a powerhouse in so many ways, this news lands with a soft thud. It’s not a surprise—the clock has been ticking since their launch—but it’s a moment of reflection for any tech enthusiast. We’re not just saying goodbye to a cycle of new features; we’re marking the passage of a flagship generation into the realm of beloved-but-retired technology. A Legacy of Innovation and. Character. The Pixel 6 series, launched in October 2021, felt like a statement. Google wasn't just making a good phone anymore; they were making their phone. The distinctive camera bar—the ...

I'm Stoked That Google Made the Pixel 10 a $799 Value-Packed Feature Monster

Alright, deep breaths everybody, because I am seriously, not-ironically, totally stoked about the Pixel 10. And not the " tech reviewer stoked " where you attempt to be level-headed and unbiased. No, this is the " I'm already checking how long I've had my phone and mentally making room for a new device " stoked. Why? Because Google just dropped a mic with the Pixel 10, not with a gloriously inflated price point, but by making it a $799 value-packed feature behemoth. For years now, it seems like the smartphone market was engaged in a game of " how high can we go? " Flagships crept up to, then went well beyond, the $1000 level . And although many of them are unquestionably marvels of engineering, my wallet more often than not felt as though it was being robbed in an alleyway. My philosophy has always been to get the most bang for my buck, and of late, "bang" typically equated to " ouch " when referring to the price of phones. Whi...

Meet the Pixel 10 Pro: What to Love and What to Rethink

By umar umk.unbox

As a self-labeled tech buff and self-admitted Google Pixel loyalist from way back in the Nexus days, each release of the new Pixel is a personal holiday. This year's Pixel 10 Pro came crashing down (a premium, satisfying thud, I should mention) onto my workspace, and I've been testing its limits. From unboxing to day-to-day drudge, and even some admittedly neurotic photography sessions, I've got opinions. Serious opinions. So, let’s dive into what I’m absolutely loving about the Pixel 10 Pro and what, frankly, has me scratching my head a little. What to Love: A Symphony of Software and Smarts 1. The Camera (Duh! But Even More So This Year): Okay, let's get the elephant in the room out of the way first. The Pixel camera has always set the benchmark, and with the 10 Pro, Google has somehow managed to push it higher again. Computational photography here isn't a party trick; it's a radical rethinking of how the world is captured by a smartphone. Low light? Don...
