Familiar plague of an ultra-fast brand-new phone getting sluggish with app-opening problems after having been one full year in use. While most call it “planned obsolescence”, or just a reason to buy another device, facts prove that “clutter” has built up in the background, consuming valuable resources of your phone over time. Not bad news since one doesn’t need to call a technician for a fix.
Hidden Background Apps

An application runs in the background once opened by the user for easy reopening. That means a 50-app freezing standby means draining quite a lot from your phone’s RAM. The fastest 5-second cure-all? Swipe up and close unused apps so your processor gets a clean slate to work on.
The Clean Cache that is Clogged up

It saves all sorts of data, such as logos or images, by various sites or applications to not download it any time. The term is cache, and this can be built up with the use of the device for months, hours, days, amounting to several gigabytes of junk data over time. Go through your settings in the browser (whatever you use Chrome or Safari) to Clear History and Website Data. Just like that, your digital cobwebs disappear.
Zombie DEMO apps

Certainly, that one app (maybe two) exists if you download it; thus-and-therefore, it’s never used again. Unbeknownst to many users (IT know how), such an app is likely to perform processes in the background-together with death updates or warning notices-generally if it’s never applied anyhow. The majority of the remover zombies are found floating around the nuance of the system for no realized need.
Your Storage is at Red Line

Put in your cellphone storage like that of a desk. The desk gets 99% covered in paper; working on it is quite hard. When storage doesn’t become full enough, it fights very much for limited space and stresses the Operating System into moving files around. It is always good practice to maintain at least 10-15% of storage free to avoid possible congestion.
Automatic App Updates

Most of the time, this is usually left on automatic update. By doing so, every time you use this app, it automatically goes to the background trying to update itself. With a particular setting in your phone, set up “Update Wi-Fi only” or better switch off automatic updates and, the best, update your apps weekly when you have a spare moment.
Overloaded Home Screens

If your home screen is full of applications and there is, let’s say, live weather, stocks ticker, or news feeds that your phone must constantly extract up-to-date information from, there are simple steps that will dramatically improve the lag experienced while swiping screens. Just remove some widgets or remove live wallpapers.
Power of the Simple Restart

For the most part, one would go through many months without even shutting the phone off. Simple restart (shut off and put back on) cleans temporary glitches, ends runaway background processes, and puts its system memory back in action. Most effective two-minute fix known.
Obsolete Program

It is terribly tempting to hit “Remind Me Later” by courtesy on software updates, but the updates usually hold bug fixes that optimize the way the software interacts with the hardware. Running an outdated version of the operating system on all the new apps is the beauty of slow. A two-minute check on “System Update” in your settings pays for itself.
Overheating Issues

If the phone gets hot to the touch, it will intentionally slow down (thermal throttling) so as not to melt any components inside. When your phone is laggy, check if the thickness of a case is preventing heat dissipation or whether the phone is just lying in the sun. Letting it sit sans case for a few minutes should cool it off enough to perform at its peak once again.
