It’s commonly understood that Android devices start to slow down after one year of constant use. It’s inevitable, some people may argue; while others think that it’s just a myth. However, there are repeated evidences that the Android device that we purchased nearly one year ago is no longer as snappy as it was. These could be some of the reasons:
1. Too many background apps
When we first open a new Android smartphone; we could find many bloatware installed by the smartphone manufacturer and network provider. Even if we haven’t installed anything yet, these pre-installed background apps can slow down the phone noticeably. The problem could get worse as we install our own apps. We should know that background app eat some amount of RAM, even if we don’t open it. Social media apps are known for their high-resources requirements and the problem could get worse on low-end devices. These apps also constantly check whether there are new notifications or updates. Social media, email and instant messaging apps want to be helpful by ensuring that we will be kept updated. In this case, we should consider whether we really need the constant checking feature to be enabled. Force-closing these apps may not be a good idea, because they can be restarted by the system. The best option is to disallow these apps from giving us notifications and updates.
2. Dirty cache
It is possible the cache of our Android device is full of junk. Cache partition is intended to provide faster performance, but it could be easily clogged. The overall performance of our Android device could drop if the cache partition is full. To prevent slowdowns, we should clean up the cache partition. Android devices have recovery console where we can wipe the cache partition.Methods for accessing the console and wiping the cache partition vary from device to device. However, in many devices; we need to shut down the system first. Turn on the phone by holding down both the power and volume buttons. One of the options is the Dalvik Cache wipe. After we do this, we should be able to restore the phone performance.
3. Nearly filled up external and internal storage’s
Android smartphones have solid-state storage and the performance will noticeably decline if the storage space fills up. It’s among many reasons why multiple Android devices have reduced performance. The internal smartphone storage could be filled with video apps, photos and other files. This should explain why a smartphone tends to get slower. Low-end smartphones with much weaker hardware are particularly more vulnerable. Devices with only 4GB of internal storage have very limited available storage, especially because the space is shared with the core Android OS and pre-installed apps. A 100-minute Full HD 1080p videos could reach more than 1GB in size, while a standard HD 720p video could be around 800MB. Many popular games could require 1GB or more to storage space for data. Even without storing high-resolution movies and demanding games, an Android smartphone with only 4GB or 8GB storage could be filled much too quickly. The common solution is to install high-capacity microSD card to store photos, videos and apps. Even so, cheap microSD cards have low data throughput and this could cause performance problems when accessing apps and videos.
4. No TRIM support
TRIM support is needed for SSD and it allows for tip-top performance. The newest Android versions include automatic TRIM support for the storage components. However, Android 4.2 and older don’t have TRIM support. It’s the reason why older Android devices get slower faster. If we have older Android smartphones and there are no options to upgrade to Android 4.3 or newer; then the only solution is to purchase a new device.
5. The phone is simply too old
It’s true that smartphones are not mechanical devices. However, it could still be affected by physical wear and tear. Materials inside our smartphones could start to wear out due to age and constant exposure to heat. Deterioration could be more pronounced if the phone is made from cheaper components. Electrical connections may start to fail, causing slowdowns and lock-ups. Eventually, components may give up and the phone could die for good. Despite their old age, some Android Eclair or Froyo devices could still be used until today. It’s likely that they don’t perform as well as they used to.
6. Heat accumulation problem
Android devices could become slower due to overheating problems. Android operating system includes a code module that adjusts the operating processor frequency based on the detected heat level. If the software senses that the phone is too hot, the operating processor frequency is clocked down to reduce generated heat. However, the lower frequency will result in throttled performance. If the phone gets too hot easily, the frequency reduction happens too often. The phone may heat up easily if we do too many things at the same time, such as using multiple radio-based features, such as 4G LTE, NFC, GPS, Bluetooth and WiFi. Watching high resolution film at full brightness and playing graphics-intensive video games could also cause the same problem. The phone could also heat up easily if the surrounding environment is hot, especially during summer.
7. Faulty custom ROM
Android smartphones are known for being highly customizable. It’s common for some users to change the ROM of their smartphones. Stock Android vanilla ROM is highly capable, but some people consider it to be boring. Custom ROMs often include various new capabilities, tweaks and themes. These new additions are often missing on the stock Android ROM. Unfortunately, inexperienced Android users may choose and flash faulty ROM into their device. Even if the ROM does run, it will do so sluggishly. The overall performance can be affected negatively and some of the promised features may fail to work properly. This could happen if users mistakenly choose buggy beta version of a custom ROM, that’s intended only for evaluation purposes before the official launch. Before installing custom ROM, it is important for us to read the notes and instructions properly. If the notes clearly say that the ROM is still being developed, then we should look for the last stable version. It is also important to make sure that the custom ROM is fully compatible with our Android smartphone model.
