Hello And Welcome Everyone!! My name is Sambhav and my partners in crime for this topic are Prachi (2014075) and Tarun(2014168). We have the topic of troubleshooting the devices we hold in our hands everyday!! We will be talking about a combination of problems that might be related to sofware and hardware. So here we go……
Battery heats up
The way to know whether a battery is heating up is to understand whether it will be too hot for your skin or not. The battery can get warm due to many reasons. Here are a few examples-
- Device being powered on
- When the device is being charged
- The battery or device will get warm when powering on, being charged, during long calls, and especially when using data intensive features like streaming media or GPS.
- Talking on the phone for longer periods of time
- Using data intensive features such as turning on the mobile data, Wi-Fi, Bluetooth, GPS or while using playing games, using GPS.
Here are some tips for troubleshooting this problem:
- If the phone is kept in extreme temperature conditions, either too cold or too hot, it should be kept at room temperature for at least 3 hours.
- There are third-party app on Android called Battery Booster. This app allows you to check battery taxing apps and therefore allow you to see third party apps which might be the main causes of your battery heating up. You can uninstall the app to stop your battery heating up.
- Also it might be a good idea to check for physical damage on the battery itself. If that is the case, then it might be a good idea to go to a repair shop to get it fixed.
- Another idea could be to try a different battery. If the battery is working fine, then the original should be replaced. If the second battery isn’t turning on the phone either, then there might be a problem in the phone and not in the battery.
Battery depletes quickly
Is your battery depleting fast? Would you like to know the solution? Well you have come to the right place!!!
Here are a few solutions to help you solve your problem:
- Firstly you need to make sure that you are not doing anything on your phone.
- it would be a good idea to start of with checking for physical damages in the battery. That could be one reason why the battery is depleting fast
- Checking the technical specifications of your phone would be a good idea to know about the expected battery life.
- You should turn on the power saving features on your smartphone. That would slow down the speed of the CPU and other features so you can get more battery life out of your smartphone.
- Adjusting backlight brightness can also get you a good battery life.
- Closing apps in the background can also increase battery life
- Making sure you are using the latest software for your device because companies will launch new power saving features in new updates which can extract more out of your battery.
- Changing batteries.
- Also turning off battery intensive tasks like mobile data, Wi-Fi, Bluetooth, GPS, Mobile Hostpot can go a long way in saving your battery life.
Problems receiving/making calls
- The first thing is to check if you have a signal to call. Make sure your device has at least 2 bars of signal.
- Try calling or receiving a call from another number to determine if the issue is with one phone number or there are problems with the phone itself.
- Restarting the phone can also help. You can also turn on airplane mode and then turn it off.
- If you still experience issues with calling, contact your service provider.
- It can happen, say if you use a SIM convertor to use a micro-SIM as a mini-SIM or a nano-SIM as a micro-SIM. This could lead to incorrect connections, leading to dropped calls. Try to get a new micro SIM (or whatever specific) from your service provider.
- Call performance nowadays, also depends on changing from 3G to 2G data services. Most users are on a combination of 3G and 2G connections, which results in phone shifting bands more often than not. You can use 2G instead of 3G for better calling performance, if you don’t use the internet too heavily. You can do that by going SETTINGS -> WIRELESS & NETWORKS. There you should see MORE then MOBILE NETWORKS (or something similar) and under that you change your network preferences.
These are steps that can be taken to solve the problem in receiving or making of calls.
Device randomly switches off
- Make sure your device’s battery is working or not which can be checked using battery troubleshooting.
- Remove the battery from the device and wait 5 seconds and reinsert the battery.
- Power on the device. You may need to press and hold the power key for 5-7 seconds.
- If you find that the display is not turning on but there is a visual, audio, or vibration cue that indicates the device is powering on, the issue is in the blank display and not anywhere else in the phone
- If possible, try a different battery. If another battery does not have the issue, the original should be replaced.
Crashing apps
To troubleshoot crashing apps:
- First of all you should look at the reviews of a particular third party app that is downloaded from your particular app store. They willl be tell you if the app is prone to crashing and therefore you can proceed with caution since you already know that this app is prone to crashing
- Restarting the phone also solves the issue of an app crashing in many cases.
- If you have an app already installed and it is crashing, then it might be a good idea to check whether that app has an update that has come out which might have many bug fixes and that can stop the app from crashing.
- It might be that updating your phone’s software would be required to fix this issue or the phone can also be reset and the app can be installed again.
- Reinstalling the app can also be another way of troubleshooting
Freezing and Slow UI
Phones typically begin to slow down as their internal storage fills up. The following troubleshooting options are for Android smartphones.
You can try doing the following:
- Try deleting unused apps and photos, or moving them to the cloud or a microSD card.
- In addition, you should close open apps that you are no longer using, delete app cache, and limit the use of live wallpapers.
- An app's cached data can be deleted be going to SETTINGS, clicking on APPS, selecting a certain app, and choosing the "Clear cache" option. Programs such as App Cache Cleaner and Clean Master, both of which are available for free from the Google Play store, can also be used to automate the process of clearing cache.
Another hardware troubleshooting that we have looked at is using a multimeter to check if the IC's on the motherboard of the phone are working or not. Here is the link to that Youtube Video
