Battery Explosion Reasons and tips to avoid it!!
WHY BATTERY BLAST



Before discussing different ways to avoid battery explosion let me first tell you the reason why batteries explode?

Batteries are made of 'lithium-ion'. Now the reason behind using this is that it is the lightest metal and the lightest solid element. Moreover, it can store energy easily. 
In our batteries, we have two electrodes one is called Cathode another is called Anode. Lithium is stored in the cathode. While charging the phone lithium stored in cathode moves towards the anode and while discharging the opposite happens. Now in any situation, if these two meets at the same time then your battery can catch fire. To avoid this we have a layer which is placed in between these two called membranes. Now if your membrane gets any damage then chances are high that battery can catch fire. 

Now here comes the question of how the membrane will get damaged?


The answer to this is very simple. In case if you phone gets overheated or may have some manufacturing defect or if your phone slipped from your hand --In these cases, the membrane can be damaged and it will stop working and then the battery can get fired.


Now as we have already know the reasons why or how the battery explodes, so now we will look at the different ways to avoid it.


Tip #1 - Never charge your phone with some other charger than yours. The charger provided by the company should only be used to charge your phone. Never use any third-party charger.

Tip #2 - Save your phone from getting extreme pressure. Sometimes we sit with our phone on pocket now in this type of situation our phone gets extreme pressure and due to this, the membrane can get affected and lead to catching fire.


Tip #3 - Protect your phone from high temperature. Sometimes people charge their phone with the car charger and while charging they place their phone in the car desk which is already heated by sunlight. Due to this phone's temperature increases and again can affect the membrane.


Tip #4 -Now the most important one-- Try to remove the cover from your phone while charging it. As when we charge our phone it already gets heated and if it is covered then it will become hotter and can lead to the battery explosion. Some people go to sleep while charging the phone and placing it under their pillow, never ever do this! This can lead to an explosion.


Tip #5 - If you observe any issue on your phone always get it right by visiting the near service center. Never give your phone to someone who is not an authorized person to get it right.

Thus if you follow these points you can surely avoid battery explosion.

Tips to save battery

In today's life, we can't live without our smartphones! They have become so important to us. We use them a lot throughout the day. Due to heavy usage, we had to charge our smartphones twice a day sometimes. Because of this we always think is there any way to save the battery of our smartphones? ---- Don't worry!! Here we will discuss the different possible ways to save your battery -- basically some "Tips to save battery".

Tip #1:- Check whether WIFI, Bluetooth or GPS in your smartphone is ON or OFF. When you don't use these things you should manually turn them OFF. In this way, you can save your battery. 

Tip #2:- You should set installed apps to update manually in Playstore settings. Otherwise in some cases it may happen that your smartphone has 16% charge and your apps update setting is set to 'Auto', in that case, though you don't really need those updates at that moment, those updates will automatically start downloading and as a result when you bring your phone out from your pocket you will see only 5% charge left. So always set apps update to - ask me before downloading.

Tip #3:- You can turn off all the unwanted sounds like the touch keypad sound or keypad lock-unlock sound. In this way, the energy consumed by the motor will be saved and will add some extra life to the battery.

Tip #6:- Trim apps from the background which you don't use often.

Tips #7:- Keep an eye on the signal strength. While you roam in remote areas with poor cellular coverage your battery suffers the most as it tries very hard to get signal strength. You can't do much here but if not so necessary you can turn ON the Airplane Mode.


Thus if you follow these tips you can surely extend your battery life.

Top Smartphone Myths (অতিকথা)

Top Smartphone MythsTop Smartphone Myths -

More RAM is BETTER! -When we look to purchase a new smartphone, we always prefer more RAM. We always go for 4GB, 6GB and nowadays even 8GB RAM smartphones. Some of us think that if we have maximum RAM in our phone then it is better than other phones. But this is not the truth! -- It's all about your choice, what kind of work are you planning to do with your new smartphone? -- Is it just for dialing and receiving calls? or Are you going to play a lot of games? (i.e. heavy resource intensive tasks). You have to decide what kind of things you are going to do with your smartphone. If you are a user who just uses your smartphone for call receiving, dialing, chatting with friends on WhatsAppFacebookTwitter, etc. then I would recommend you to go for 2GB RAM as that is more than enough for you. But if you want to use your smartphone heavily then you should go for 4GB or higher RAM smartphones. More RAM support means you can open a lot of processes (i.e. Apps) in the background simultaneously without slowing your smartphone.

The price of your smartphone largely varies with RAM. The more RAM    it will have, the more costly it will be. Thus, think well whether you need more RAM or not depending on your usage. Having extra RAM in your phone will not going to help you rather it will be a waste of memory as well as your money.

Powerbank charging isn't good! - Many of us think that Powerbank charging is bad for long battery life. But this is a myth. It just gives the same output as your adapter. 

Tracking of phones - We think that if we activate the Airplane mode  ON in our smartphones -none can trace us. This is a pure myth. Even if the sim is taken out from the phone then also it can be traceable with the IMEI no. You can find your device IMEI no by dialing *#06#. Even if you switch off your phone it may be traceable if it is already hacked by an installed app in your phone. Though you switched off your phone those apps will not let your phone go completely switched off and you can be tracked. Only two ways are:- Either you detach the battery from your smartphone or use an anti-tracking signal blocker pouch case bag handset that doesn't allow passing of any radio wave through your smartphone.

Apps from Play store - We feel so confident when it comes to apps we download from Play store but it's not like that. Many cases were found when some apps in play stores are targeting users and collecting personal data from their smartphones. Later, these lead to hacking. Thus we need to be careful while installing any app from play store.

এটিএম ফ্রড থেকে কিভাবে নিজেকে বাঁচাবেন?


How to save yourself from ATM fraud

Around 200+ people have lost more than Rs 10 lakh to ATM fraud in Bangalore. 

Here is how to reduce the chances of ATM and mobile frauds, and how to keep your money safe.


Fraudsters use an advance card skimmers to read the information from the magnetic stripe on the debit card/credit card and later illegally withdraw money from people's accounts. There have been several cases of ATM and mobile frauds in the past also, but nowadays this issue is growing massively. So, How to save yourself from ATM fraud?


Set an unpredictable(not guessable) PIN:- The PIN of your debit/credit card should not be easily guessable. So, avoid using your date of birth as the PIN or last 4 digits of your phone number as the PIN, etc. to increase privacy. Set a PIN that is not easy to guess and memorize it. Don't write it down anywhere except a location where you are fully sure that it will remain secure. Try to change the PIN time to time to add extra security.

Nowadays it's very easy to do that - You can set your new ATM PIN in any ATM machine by following just 2 steps-
1. Generate OTP 
2. Set the new ATM PIN 
..and it's done.

Two-factor authentication is a must: While doing any online transaction(payment), a two-factor authentication ensures notification on your registered mobile number each time your card is in use. An OTP will be generated and sent to your mobile, which needs to be entered in order to complete a transaction. If you receive any text or notification on your mobile without trying to log in, you should inform the bank immediately.

Swipe your card carefully: Watch out for skimmers at ATMs before you swipe your card. It will just take a few seconds to notice if any skimmer is there or not. Look for the area where you swipe your card, if you notice any loose or unusual part then avoid using that ATM machine.

Google said that they have coded the UIDAI number in the contact list

UIDAI number in the contact list


UIDAI number in the contact listThe mystery of UIDAI number in the contact list finally gets solved on late Friday night, with Android's parent company Google, stating it was at their end that the old helpline number — 1800-300-1947 — was coded into Android-powered devices back in 2014. 

A Google spokesperson said, "Our internal review has revealed that in 2014, the then UIDAI helpline number and the 112 distress helpline number were inadvertently coded into the setup-wizard...Since the numbers get listed on a user’s contact list these get transferred accordingly to the contacts on any new device. We are sorry for any concern that this might have caused and would like to assure everyone that this is not a situation of an unauthorized access of their Android devices. Users can manually delete the number from their devices. We will work towards fixing this in an upcoming release of SetUp wizard which will be made available to OEMs over the next few weeks.”
