In this article we are going to see the full pros and cons of the in build battery. Before looking the negative side, lets see the positive side.AdvantagesUsually most of the smart phones with inbuilt battery has external memory card slot and SIM slot. So the users didn’t want to remove the back cover every time. The time of removing the battery for switching the SIM cards is also saved.The mobile cover won’t break since its fixed with the cell phone and users won’t have to deal with it. Thus the mobile can be used for the longer period of the time.The dust won’t enter in the internal parts of the mobile since all sides are mostly sealed. So the mobile looks fresh and new.The smart phone will look more solid fit and the manufactures can make slimmer mobile phones by reducing the gaps and the slimmer phone looks more stylish.Usually the inbuilt batteries have higher lifetime than the removable batteries.DisadvantagesYou can’t use a spare or a secondary battery when your primary battery loses all its juice, this is the major drawback of non removable battery.If your mobile gets struck and all your controls stops working then you can’t reset by removing the battery. Now the only option that left for is to wait until the charge gets dry up.All type of battery will be damaged when short circuit occurs and the inbuilt batteries are not the exception. Its not easy to replace the old battery with a newer one, in case the fixed built in battery fails.You may need to pay separately for the person who replaces the old battery with the new one.
Why mobile phones are implementing hybrid SIM (the second slot can be either be used for second SIM or memory card) while simple dual SIM is better?
I think it may be due to cost factor albeit should save only a fraction for the manufacturer. It also saves the manufacturer from providing another slot in the phone’s body and in the phone’s mother board - which may be a good idea for phones that are water resistant contributing more for saving cost. That said, it could be that the manufacturers “assume” customers may see it as a “cool” feature with hybrid sim slot. But, just like most of the customers, I hate this idea of hybrid slot. It really limits the end user of his flexibility in using the mobile. If manufacturers really need to impress customers why not Dual Sim with Hybrid slot PLUS a micro SD card slot? I’d call that as flexibility and “cool”. I prefer saving all the media in my sd card slot rather than the phone’s internal memory for one simple reason - security. I usually upgrade my phone every two years(if I’m that patient), and when I exchange I just remove the sd card and put it on my new mobile. Saves me a lot of time and retains the folder structure. Moreover, I can rest assured that no one can extract any data from my old mobile that I trade(even after format - using file recovery softwares). On the other hand, having a dual sim enables my to use data from one slot and voice from the second. “JIO”- what else. I’d just use Jio purely for data and use Airtel for calls. I had to reconsider lot of good phones just for this one reason - hybrid sim slot. Hope the manufacturers listen.

What creative profession would you enter and why?
I would love to be a professional model / model railroad designer-builder... and add to it a store / production facility. I've been building models for almost 40 years now... from the days of balsa, glue, and tissue paper to now where I CAD draw a model and turn it out on a CAD machine with injection molding for "mass production" While I agree that video games can be "creative"... I think kids / young adults need to get off their butts and BUILD something !! Building models as a child / teen led me into a 26 year career in US Naval Aviaton... and the skills learned there gave me my current "semi-retirement" career as a rancher / farmer / vinter. When we built our house 8 years ago on our ranch... one of the things I designed in was a 60x60 foot basement for my "dream" model railroad layout and modelling / micro-machine shop. Just wish I could make a living at it !
What is the purpose of a SIM card? What information does it hold? I was told it contained internet history, contacts, etc. Is this correct?
SIM - Subscriber identification module is basically a Chip which contains Some information to handshake Mobile Device with Telecom OperatorSIM Doesn’t Not hold your Call Log information, Internet Browsing History, Call Duration.What information is STORED in SIM(SIM) is an integrated circuit chip that is intended to securely store the1. International mobile subscriber identity (IMSI) number. This Changes you do MNP2. Mobile number (MS-ISDN). Remains same if you Do MNP3. Authentication key, which are used to identify and authenticate subscribers4. It is also possible to store contacts on many SIM cards. such as contact list data and SMS messages. Most SIM cards have a capacity between 32 to 256 KB.5. SIM cards are always used on GSM phones(2G/3G) and 4G (USIM)6. SIM also contains Temporary information related to the local network ( in in the form of LAI), a list of the services the user has access to, and two passwords: a personal identification number (PIN) for ordinary use, and a personal unblocking code (PUK) for PIN unlocking.7. SIM card also conatains SMSC Center informations which burnt by Telecom Operator before it is Handed over to you.LAI : When the Subscriber Changes locations, it stores the new LAI to the SIM and sends it back to the operator network with its new location. If the device is power cycled, it will take data off the SIM, and search for the prior LAI.Type of SIMSIM cards have been made smaller over the years; functionality is independent of format.Full-size SIM were followed by mini-SIMmicro-SIM,nano-SIM.SIM cards are also made to be embedded in devices.SIMs for Machine2 Machine applications are available in a surface mount SON-8 package which may be soldered directly onto a circuit board. In future you Devices will be contacting each other due this e.gYour Refrigerator will Inform Shopping Mall That Vegetable are required in refrigeratorPlants will information Water Resovior that it needs water supplyYour home Solor plant will inform city Electrical board that you have surplus electricity to sell /charity.SIM Chip Information
