Hey, guys, it's me Rahul and this is a video that I wanted to do for a very long time,
finally got time to do it.
So without further ado, let's begin.
The reason why I decided to make a video like this is that I absolutely love customizing
and turning an old phone at least to an usable one.
so before we get started, make sure that your device is rooted and has a custom recovery
installed on it.
If you haven't done any of that go ahead and do it, I cannot exactly explain how to root
and install custom recovery because the procedures differ based on the phone that you are using.
If you are too scared to root your phone then check the description down below there will
be a timestamp click on that, it will skip this video to a part where I explain a way
to stop apps from running in the background on non-rooted devices.
There are multiple ways to improve the performance of an old device, I will explain all of them
in this video.
One of the main reasons why an old device becomes so laggy and slow is because of the
bloatware apps that come with it.
Most of These apps are not useful at all.
So first we need to get rid of them.
The app that I strongly recommend is system app remover, it is an awesome app to remove
system apps and batch uninstall applications.So install the app from the link in the description
then open it and select all the bloatware apps and click on uninstall and wait for a
couple of minutes.
After you have done doing all that just restart your device.
You might immediately notice a small if not significant improvement in the performance.
Ok, that is just one of the simple things that we are doing.
Now we are moving on to the next stage
Now you have removed the unwanted apps. but what if the app that potential making your
phone slow is an app that you use on a regular basis.
Then there is a way to fix that.
What we are gonna be basically doing is force stopping that app from running in the background
so that way, that particular app won't use any resources such as memory and CPU. there
are of course a dozen of apps out there which can do that for you.
I will leave the links to ..at least 3 in the description down below.
An app that I'm using for a long time is greenify, it is a popular app among root users, it has
a very simple UI and it works really well.
Not only these apps improve the performance of a device, but it also saves some juice
too.
I don't recommend force stopping an app that you use very frequently because that
app has to load in every bit of data it needs back in to memory again to open up, which
will take a bit of time, and makes your phone's performance even worse.
So use greenify on apps that you don't use that often.
Another app that I recommend is shut app, this app doesn't require root access, but
it takes a lot of time to force stop applications, but if you are using greenify it does it in
seconds.
Another app that I'm using for a couple of months is icebox, besides stopping apps from
running in the background, it will also hide the apps that you have selected from the launcher
as well.
I don't recommend you to use all of the apps that I just mentioned at once, just use one
because that's pretty much all you need.And also don't use any fake battery saver apps,
because to be honest, they all are trash.and it makes your phone even worse, so please
don't use those "battery saver" apps.
There is an app called xposed installer, you can use it with greenify to unlock more features.
Installing xposed installer onto your phone can be a tough job if you have no experience
with root apps, so I will leave a link to a tutorial in the description.
So if you have any doubt regarding this check it out.
Talking of xposed installer, there is another awesome app that you can use with xposed installer
to save some juice.
the app is called amplify, You can download it for free from the xposed installer app.
So amplify is an app that put applications to sleep, the simple way to explain what exactly
this app does,, is to consider a situation like this, you locked and put away your phone
and then there is an app trying to wake it up, let's say that app wants to send a notification
alert, if you have enabled amplify then amplify would say "no you cannot wake up the phone
right now, I will let you send this alert another time" so that is basically what amplify
does, It is very similar to the doze feature in Android.
the app is a bit difficult to use.
But once you get hang of it, it is pretty easy.
You can also use magisk mods to kind of do the same things, but for this video i'm
assuming you are using an older device.
So i'm gonna be talking about some mods that works on older versions of android.
Ok, Now I have covered all the things that you can do with apps, So now we are moving
to the next level.
In which we are gonna be dealing with custom ROMs and Custom kernels.
Before that, let's look at what is a ROM and a kernel is.
ROM:"A file containing the executable instructions (a system image) of an Android OS and affiliated
apps"
KERNEL: "It is the central part of an operating system.
It manages the tasks of the computer and the hardware - most notably memory and CPU time."
Those are very simple explanations.Now you have got a basic idea about ROM and kernel,
Let's see how it affects the performance of a device.
ROM is basically the operating system, that manages all the files and operations.
ROM also manages the user interface, which plays a big role in the experience that you
get out of a phone.
User interfaces can sometimes make your phone laggy even if your device has top of the line
specs.
The kernel on the hand is a piece of software which manages memory access for apps, You
can think of kernel as a link between a software and a hardware.
It is one of the core components of an OS.
It also plays a big role in the overall performance of a device because kernel deals with the
memory management and communication.If I explain more, it is gonna sound even more complicated.
So I'm not gonna do that
The last thing that you can do to improve the performance of a device is by flashing
a custom ROM and a custom kernel onto the device.
It might sound pretty complicated but, it is actually very simple.
The ROM that comes with the phone that is preinstalled on your device by companies is
called a "stock ROM".
One of the main problems with these stock ROMs is that companies will add skins and
some features on top of the original android to make it look appealing.
In return of these modifications, the software part of a device will perform poorly, lags
and glitches will happen.I'm not saying all Skinned Stock ROMs are bad, I actually like
some.
To install a good custom ROM onto your device, first you need to find one, So this is what
you have to do,
go to forum.xda-developers.com then type in the name of your device here and it will take
you to this page, from here click on Android development then click on ROMS.If your device
isn't popular enough it won't show up in the search bar, in that case, do a google
search like this.
Custom ROM followed by your phone model followed by site:forum.xda-developers.com , I will
leave an example in the description so, it will be easy for you to just copy and paste
it on to your search bar.
I also want to say that, xda is not the only place from where you can download custom ROMs.
There are actually a couple of awesome websites, but the reason why I recommend xda is that,
90% of custom roms are built by an xda member, and if you face any issues while installing
or after installing, there is a community to help you solve those problems.
Selecting a custom rom can be a pretty tough job, so Read through the features and bugs
reported by the users and download the one that you like.
You could do the same for finding a custom kernel as well.
Flashing a custom kernel isn't necessary because most roms already have kernel files in them,
so if you flash a custom rom, the kernel will also be installed onto your phone.
Custom Kernel has so many cool features such as swap partition, CPU overclock support,
advanced color controls, and "multi rom" support.
So read through the forum post and carefully select one kernel that you like and download
the files,
If you have downloaded the files using a PC, move the files to your phone.
There are a couple ways to install custom roms and kernels, the common way is by using
custom recoveries, It is fairly simple these days to flash a rom file because new custom
recoveries have a very simple UI.
It doesn't matter which custom recovery you are using since all of them kind of have the
same UI.
Ok, now I will show you how to flash a custom rom Just reboot into recovery, if that sounds
pretty complicated to you, then download and an app called reboot recovery from the link
in the description.So you don't have to press and hold multiple buttons to get into recovery
mode.
when you see some fancy text and other UI elements, look for something similar to "backup
and restore".
tap on it, and backup your current rom, because if something goes wrong you can always restore.
Before flashing a rom you should wipe all the cache and user data and system.
So for that look for something that says " wipe" select that menu and wipe the cache,system
and userdata.
you are basically factory resetting your phone now.
Sometimes you might need to wipe some other things too, so read the forum post carefully.
Then look for something similar to "install zip".Tap on it, select the custom rom zip
file and just install it.
If you want to flash a custom kernel you must do it after you have installed the rom, otherwise,
the custom kernel will get replaced by the kernel that comes with the custom rom.
To install a custom kernel follow the same steps ie, select the zip file and flash it
and then just restart your device.
If you come across any problem just go to that Custom ROM's forum thread and report
the problem that you had , and developers will help you to solve it.If that problem
persists just restore your rom back and try again with another rom file.
If everything goes well, You have a new device on your hand.The first thing that you want
to do is, make use of the features of the kernel and the rom, to enhance user experience.
for example, if the custom kernel supports swap partition use that feature to increase
the ram . Little things like that can deliver a massive difference.
You can also install apps like greenify, amplify or icebox to stop apps from running in the
background.
Now, I have pretty much covered all the ways that I know to improve performance and battery
life of your smartphone.
What if the phone that you are using is not that popular and don't have any custom roms
available and it is not usable as a phone, So, in that case, the best that you can do
is use your smartphone as a security cam.
It is actually pretty easy to setup, I will show it to you quickly.
Download this app called "Ip webcam" from play store, it is free.
Make sure that you have connected your phone to your wireless router Then open the app,
and tap on start server and then follow the instructions, it is pretty simple.
Setting up your smartphone as a security cam is not a great solution and it is not reliable
either.
What I will do in this case.is I will use that particular device as a test device for
testing out different things, such as for testing different applications, for testing
whether an app works on certain conditions and things like that.
That's pretty much all I know about this topic.
it was really difficult to make this video, So feel free to share this with your friends
and family and subscribe if you want to see more videos like this.
And I will talk to you guys in my next video
