Speed up a slow Nexus 5 after upgrading to Android Lollipop
Right after upgrading my phone from Android Kitkat 4.4.4 to Lollipop 5.0 I had a disappointed face for the whole day because of the new design and the extreme UI lag, which is pretty unusual for a fast smartphone.
I already complained (yes, I really like to do that!) about the design of the new Google Calendar App, but after the system update the whole UI got a new design. I like the new notification menu and the settings menu, but I really preferred the app-switching menu, the bottom and top bar, the apps screen and the transparency of Kitkat. I guess I have to get used to it.
But the point is, the phone was incredibly slow! Here are some solutions.
Simple cache wipe
The quite simple and effective solution I found on this thread was to wipe the system cache. A fast way to clean the cache of all apps is Settings -> Memory -> Cache.
This procedure is also useful to restore some free space when needed. I tried to perform this cache cleaning with no results about swiftness.
Complete cache wipe
To clean completely the cache of your phone on a deeper level, in my case for a Nexus 5 (look it up for your phone), these steps are good, but I added a few points to them. If you want some images of the process, check this page out.
- Switch off your Nexus 5.
- Long press on the VOLUME UP + VOLUME DOWN + POWER keys at the same time for about 4 seconds until the phone vibrates.
- You should then see an image of an Android lying on its back pops up.
- Hit the VOLUME DOWN twice until you see “Recovery mode” is displayed on the upper part of the screen.
- Hit the POWER key to restart in “Recovery mode.”
- You should then see an image of an Android with a red triangle appears.
- Hold down the POWER key and shortly press the VOLUME UP key. Release all keys when the Android System Recovery screen shows up.
- Use the VOLUME keys to navigate to Wipe cache partition. Be very careful NOT to select the Wipe data/factory reset option which performs a complete reset and “deletes” all your data.
- Press the POWER key to confirm.
- The wiping will take about 5 minutes. The Nexus 5 will then restart.
As stated here
In fact, doing a system cache will NOT delete any of your personal info, but only the background and application cache. Cache is stored data on the phone which allows apps to load quicker, it’s like the data is on standby until you need it again. Wiping it simply means that the app will have to reload the data.
Remember that wiping your cache may speed up your Android in any occasion. Try it on some older phone to bring it back to life a bit
