Is there really any change in new iPhone XS and XS Max?

iPhone XS and XS Max

So it's about 3-4 days since apple launched it's new phones that are iPhone XS and iPhone XS Max. There is one more iPhone this year that is iPhone XR which is a cheaper version. In this article we are going to see that is there really any difference between iPhone X and new iPhone XS and XS Max. iPhone X was the first phone from the company which has end to end display with small bezels. Last year with the launch of iPhone X, Apple introduced an all new phone with new design, new camera, new chip and many other new features. It means there were a lot of changes in iPhone X from it's previous iPhones. But let's see whether this year apple has provided something new or not.
The initial impression of a smartphone comes from it's design. iPhone XS and XS Max comes with exactly same design as that of iPhone X, with same notch display and glass-stainless steel body. But iPhone XS has a screen size of 5.8" while iPhone XS Max comes with a massive screen size of 6.5". As iPhone XS comes with 5.8" display it looks identical to iPhone X. But there is only one thing which can differentiate it from iPhone X that is the new Gold color. Both the new iPhones come in three colors that are Space Grey, Silver and Gold. Yes Gold is the new color and it definitely looks better than other two colors. The display on both the phones are still OLED type with 19.5:9 aspect ratio. iPhone XS has display resolution of 1125*2436 pixels and that on iPhone XS Max is 1242*2688 pixels. Both the displays come with scratch resistant glass and oleophobic coating.
Also both the phones have notch at the top in front. The notch is also exactly same as iPhone X which houses an ear piece, front camera, IR camera, microphone, dot projector, ambient light sensor and proximity sesnor. These different sensors coordinate together to unlock the phone with face ID. Face ID is present on both of the iPhones and it will be faster than the previous generation. Both the iPhones now have IP68 rating. So we have arrived to a conclusion that there is no major difference in the design of new iPhones from iPhone X.
Now take a look at the major change in the phones that is the all new A12 Bionic chip. The new chip is manufactured on all new 7nm architecture which further increases the transistor density thus improving the performance of the device. This chipset is a hexacore chip with two powerful cores and four power efficient cores. This new 7nm architecture chip will increase the performance and improve the power efficiency.
Last year, Apple has a dual core neural engine in it's A11 chip. This year A12 Bionic chip has an octa core neural engine. This neural engine helps in machine learning and artificial intelligence of the phone. That means it assist in functions like face ID, Animoji, Augmented reality and many other things. As this year we have an octa core neural engine, all the AI functions of the phone will be much faster.
Now let's have a look at the camera of the phone. There is not much difference in the camera department in the hardware part. iPhone XS and iPhone XS Max both have same dual camera setup as that on iPhone X that is 12MP,f/1.8 + 12MP,f/2.4 where second lens is a telephoto lens. The only difference in the camera hardware is that now the primary lens has bigger pixel size of 1.4┬Ám. The front camera is also same as 7MP,f/2.2 lens.
The back camera can record videos upto 2160p @60fps. It can also record 1080p slomo videos @240fps. It is a little bit disappointing that apple phones can only record slomo videos @240fps while other brands like Samsung and even Oneplus are giving 960fps and 480fps slomo video recording respectively. The front camera can record videos upto 1080p @60fps. The portrait mode is present on both front as well as back cameras. The telephoto lens helps in 2x optical zoom in the camera.
Though iPhone XS and XS max's camera don't have a lot of difference in the hardware part, there are differences in the software part. With the A12 chip there is all new ISP for cameras. It helps in producing better photographs by processing them properly. There is an all new HDR mode just like on pixel phones. So the image quality is going to increase with this phone. Also there is a mode in the phone where you can change the depth of feel in the shot even after capturing it. It helps in choosing us how much amount of blur we require in the background. All previous features like lightening photos are still present on the device.
iPhone XS and XS Max both comes with iOS 12 installed. We all know about the software experience of the apple which is really amazing. Apple pays a lot of attention in the software part. It does optimization between the software and the hardware so well that every iPhone of the year becomes the most fluid phone. Now the Sri has become more advanced. The gesture functionality is still there on both the iPhones. Both iPhones come in three memory specification 64/256/512 GB internal with 4GB of RAM. There is no slot for micro SD. Now new iPhones support e-SIM and there is one slot for physical SIM as well. So now technically they are dual SIM devices.
iPhone XS starts at $999 and iPhone XS Max at $1099 for 64GB version. Now the main question arises, should you upgrade? If you own an iPhone X and planning to buy iPhone XS or XS Max, stop there because you can see that only there is one major difference that is A12 Bionic chip. There is no other major change in the devices. But if you own a iPhone 8/7/6, you can definitely upgrade to these new devices because you will see a lot of differences.

Rumour roundup: iPhones 2018

iPhones 2018: All the Rumors
Apple is all setup to launch it's new iPhones of this year on September 12. We have heard of lot of rumors about the new iPhones till now. And we are going to discuss all those rumors today in this article whether be it's display, processor, name, design and the rest.
First thing which comes in mind is that how many phones will Apple launch this year as it launched three new iPhones last year in the event that are iPhone 8, iPhone 8 plus and iPhone X among which iPhone X is the special edition phone on Apple's iPhone  10th anniversary. This year also there will be three iPhones at the event among which two will be successor to iPhone X and one will be the cheaper one. 
And now you must be thinking what will be their names, so the cheaper one will be known as iPhone 9 and the other two will be iPhone XS and iPhone XS Plus. But we have reports that Plus version will be named iPhone XS Max. So whatever be the names let's discuss the internals of the phone and their design. iPhone X will have a screen size of 5.8" while XS plus will have screen size of 6.5". The design of both the phones will be very similar to iPhone X which means that notch design. 
Both the phones will be having OLED displays on the front. And this time the quality of the displays will be even better than iPhone X.  The front screen will be same with very small bezels. The notch on top will be having all the sensors, camera and face ID technology which unlocks the phone by firing infrared waves on face. Also the back will be made up of glass and the placement of the rear camera will be same.
The design of iPhone 9 is unknown. It is expected that it will have a screen size of 6.1". It will also be having the bezeless screen on the front just like other two models. But we are doubtful that the company will provide the same notch on this iPhone or different. The screen of this phone will be a LCD display and that too with lower resolution than other two iPhones. We are still unsure about the back of the phone whether it will be glass or metal. This will be cheaper than other two phones so company has to do some cost cutting.
iPhones are always known for their fast performance. First of all their A series chips are really good and secondly the optimization between hardware and software is awesome which helps in improving the performance of the phone. This year iPhone XS and XS plus will be powered by the all new A-12 chip. This chipset will be based on 7nm architecture thus making the chip size small and comparatively faster. The performance will be really good by seeing the track record of Apple. Also there will be a all new GPU for the phone which will increase the performance by 20-25% as per the rumors say. iPhone 9 will also have the same processor as that of other two iPhones.
This year the iPhones will be available in multi colors but the frame will remain same on all the phones that is stainless steel in iPhone XS and XS Plus while iPhone 9 on the other hand will have an aluminum frame. Both iPhone XS and XS plus are rumored to come in dual SIM models which will be the first iPhones officially to have dual SIM.
This year camera is also rumored to be improved. iPhone XS is rumored to have dual rear camera setup, iPhone XS plus to have triple camera setup and iPhone 9 to have a single rear camera setup. If this news is true, iPhone XS plus will be the second phone in the  market to have triple camera setup. Also there will be increment in battery capacity of the phones. iPhone XS Plus is rumored to have a massive battery of 3400 mah and iPhone XS to have a battery of 2700 mah. 
And lastly, these are just rumors and leaks, nobody knows the real story. But there are not many days left for the real picture to be revealed. Apple is holding an event on September 12 in California, US where it will reveal all three new iPhones along with new Apple watch and new iPad. But I am most excited about the cheaper version of iPhone this year that is iPhone 9.

Xiaomi launched it's first Mi Wireless charger just at $10

Mi Wireless Charger

 We all must have heard about the wireless charging which is getting really famous these days in phones to charge the battery. As the name implies, wireless charging means charging the device without any wires, directly connected to your phone. For this you just need a wireless charging pad and a phone which supports fast charging. We just have to put the phone on the pad and it will charge your phone's battery. This pad will get power from the electric mains via a charger. So basically this pad will be connected to the charger and phone will be placed on this pad. We won't go into deep how this actually works.
These days this wireless charging is mainly available only in flagship devices as there is some extra arrangement needed in the phone. This extra arrangement adds to the cost of the phone. So this is generally available in the flagship phones which can the bear the cost of this wireless charging. Phones like Samsung S series, Note series, iPhones, LG flagships and many more support this. There are a lot of wireless chargers available in the market but they are actually really costly. So keeping this in mind, Xiaomi came up with a cheap wireless charger known as Mi Wireless Charger.

Mi wireless charger is based on generally accepted Qi standard. So it will only charge your phone if your phone also supports Qi standard wireless charging. This charger can support charging upto 10W. The body of this pad is made up of aluminum with silicone layer at top. It is connected to charger via a USB Type-C port. If you will use a fast charger of 18W this pad will be able to charge the phone at 10W or 7.5W and if you will use a normal 10W charger the phone can be charged at 5W.

This pad also has an LED light to tell whether your phone is charging or not. Also it can charge the phone upto a distance of 4mm, so the phone can be charged even with a case applied. The wireless charger comes with a lot of protective features such as temperature protection, short circuit protection, overvoltage protection and power protection. These protective features will help in safe charging of your phone and in case of any emergency these will be helpful in protecting your phone or any other hazard. This charger can charge phones like iPhone X, iPhone 8/ 8plus at 7.5W and Samsung S9/ S9+ and Note 9 at a rate of 10W.  

But this charger is only available in China till now. And there are no words of it's availability in other markets. But just at CNY 69 or $10 it is a great deal.

Why do people want a 3.5mm jack in phones?

3.5mm headphone jack
Smartphones are the devices which are meant for doing a lot of tasks in very less time and without any difficulty. One of those tasks is entertainment. Smartphone is a very good source of entertainment. You can play games here, listen to music, watch movies, videos and a lot of other things. But all of these entertainment tasks are of no use until there is no audio. Audio lets you listen to the sound and make all these tasks more entertaining. So audio is a really important component. For sound output there is a speaker in the smartphone which converts electrical signal to sound.  
Instead of this speaker there is one more thing by which we can listen to sound and that is headphone jack. This is in the shape of a cylindrical hole in the phone and we connect a 3.5mm connector to it which is there in headphone or earphone. These headphones are really useful as listening to audio via headphones have a totally different fun. The sound will be really immersive, nobody will be able to know what you are listening to and there is also total noise cancellation, so there won't any noise interruption with your audio.
But these days smartphone companies are trying to vanish ports in the phone so many of the companies are ditching 3.5 mm headphone jack in their phones. But this creates one more problem of not listening to audio via headphone jack. The quality of sound via headphone jack is really good. But as this jack is vanishing we have to rely on some other alternatives such as wireless headsets. These wireless headsets connect via Bluetooth to your device. The sound via these Bluetooth connected headsets is not great as the wired headsets which connect with 3.5mm jack. 
These Bluetooth connected headsets doesn't address latency issues which proves problematic while gaming and watching videos and it's an issue we don't get with the wired headsets. Also the sound quality is not as good as wired headsets. So Qualcomm noticed this issue carefully and came up with a really cool thing at IFA 2018.
At IFA 2018 Qualcomm announced a new version of aptX audio platform. With this aptX you will be able to listen really high resolution, robust and immersive audio through wireless technology, which means there won't be any requirement of 3.5 jack in the phone. And also it is not just focused on music listening, there are other things as well like gaming and watching videos. It dynamically adjusts audio performance without any manual control.
This is really cool step by QUALCOMM as many of the companies are ditching the headphone jack in their devices. Qualcomm is saying that it will come with it's latest flagship chip that is Snapdragon 855 which will be announced in December this year and the first device powering this chip will most probably be launched at MWC 2019. So the first device having this new Bluetooth technology will be available in 2019. The company is claiming that this new technology will definitely replace 3.5 mm jack from the phone but real picture will come out only when this will be tested in 2019.

Huawei unveiled first chipset built on 7nm architecture

Hisilicon Kirin 980

 SOC or System on chip is a really important component of a phone. It has many other small components like processing chip, ISP, memory, RAM and many more. So basically it is in the form of a small chip with all other components embedded on it. These SOCs are built on some architecture. This architecture basically means the transistor size. Each year the size of transistor is getting smaller like 20nm to 16nm, 16nm to 14nm and so on. With transistor size getting smaller the performance  and battery consumption of chipset improves as electrons consumes less time and power to move in a smaller transistor. Now in the market we have chipsets like Qualcomm snapdragon 845 or Hisilicon Kirin 970 which are built on 10nm architecture.

But now it's time for the successor to Hisilicon Kirin 970 chipset that is Hisilicon Kirin 980 chip which is built on 7nm architecture. This is based on an octa core chipset with four cortex A-73 cores among which two are powerful cores and two less powerful cores for better power efficiency. Rest of the four cores are Cortex A-55 cores and these cores are less powerful than Cortex A-73 cores. Huawei also has something known as 'Flex Scheduling', which helps in powering right cores for the right tasks and thus result in better battery life.

For better graphics there is Mali G76-GPU which was announced in May. This GPU will help in high graphic intensive tasks and will also result in better gaming experience. This can also take advantage of clock-boosting technology which results in better performance when there is some high graphic intensive task is going on. This GPU is far better than it's predecessor that is Mali-G72.

Hisilicon Kirin 980 chipset is the first to support LPDDR4X memory. It also supports 1.4Gbps Cat 21 LTE modem and fast WiFi speeds. This is the first chip to come with dual NPU technology which means it has two NPU chips instead of just one in the previous version. This NPU results in better AI functions in the phone. It will make the phone more intelligent and thus results in better accuracy in AI tasks. It also improve the speed of AI tasks.

There is one more thing worth mentioning in Kirin 980 and that is it's good camera performance which is possible due to all new ISP. This is the fourth generation of Huawei's ISP. And it's really good due to features like multi camera support, HDR color reproduction, multi pass noise reduction, more data throughput and many more.

Now you must be thinking how does it perform against the blazing fast Qualcomm chip that is Snapdragon 845.This can't be answered right now. Huawei is claiming that it will be 20% faster than 10nm chips. But nobody has trust on claims, real picture will come out only when phone having Kirin 980 will be launched. First of the  phones which will have Kirin 980 chip are Huawei Mate 20 and Mate 20 pro which will be launched in October. So the performance of the chips can be tested then only. But the performance of the chip is expected to be really good as Kirin 970 is also one of the fastest chips in the market.

14nm, 10nm or 7nm: What deos it mean in a SOC architeture?

Nanometer architecture of chipset?
We all use phones a lot these days that it has become a very important component in our life. These phones are just like our small computers but with smaller screen and less performance. Just like computer's processor these phones have small chips known as SOCs. These SOCs are built on certain architecture. So what does this architecture mean with respect to these SOCs. This is the thing which we are going to discuss in this article.
As the name implies architecture mean the engineering design of the SOC. SOC stands for System on Chip. This chipset is made up of Integrated Circuits. Integrated Circuit is a set of electronic circuits on flat piece. Integrated circuit is made up of integration of large number tiny transistors on a small chip. Transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.
Now we must have heard of various SOCs built on that much nanometer architecture. So what does this term nanometer actually mean? This nanometer tells us the size of these tiny transistors which are used on the chip. We must have heard various chips with their respective nanometer architecture. We have also seen that these nanometers count is decreasing with the new chipsets coming. So why?
The explanation to this is that smaller transistor sizes are more power efficient. Not only the power it's performance will also be good. As transistors get tinier and tightly packed the electrons don't have to travel so far while moving between them. This results in saving of both time and energy. So as time  reduces the processor can do tasks quickly thus improving the performance. And as energy consumption reduces more power efficient will be the phone and hence the battery life of the phone will be better. That's why companies like QUALCOMM and Samsung are manufacturing chipsets with less nanometer count these days for smartphones. The latest chipsets Exynos 9810 and Qualcomm's Snapdragon 845 are both built on 7nm architecture.

LG G7+: A True Flagship just at 40000 INR or $570

LG G7+ ThinQ

 LG was among one of the most prominent smartphone brands to produce really good flagship phones or other phones as well earlier. But from last few years it's sales have gone really bad. This is due to better smartphone alternatives in the market such as Samsung, Apple and even OnePlus. So from last few years LG's smartphone hasn't gained much profit. But it doesn't mean that their phones are not good. The thing is that there is not much innovation in their phones. Also LG always price it's smartphones as equivalent to Samsung or other premium smartphone brands. So people prefer other brands over LG because they got everything right in their bucket.
But this time LG has understood it's position in market and has priced it's new flagship phone very aggressively here in India. LG G7+ ThinQ is the successor to last year's flagship LG G6. LG has priced this phone at 40000 INR here in India which translates to around $570. The pricing is really insane for a flagship smartphone, so let's see, Is this smartphone worth it's pricing or not.
Size: 6.1"
Display: IPS LCD type, 19.5:9 aspect ratio                 
Resolution: 1440*2280 pixels
Weight: 162 grams
SIM: Hybrid Dual Sim
Chipset: Qualcomm Snapdragon 845
GPU: Adreno 630
OS: LG UX based on Android 8.0 Oreo
Battery: 3000 mah
Rear: Dual 16MP,f/1.6 + 16MP,f/1.9, OIS
Video: 2160p @30fps
Front: 8MP,f/1.9
3.5 mm jack: Yes
Sensors: Ambient light sensor, Fingerprint, Accelerometer, Gyro, Proximity, Compass, Barometer

 The design of LG G7 ThinQ is same as many other  smartphones these days that is Notch display. There is a notch at front on top of the phone. This notch houses the ear piece and other sensors such as proximity and it also houses the front camera. There is a 6.1" tall screen on front. This display is an IPS LCD type display with 19.5:9 aspect ratio. The screen is protected by Corning Gorilla Glass 5  on front. This display is a 2K resolution display. There is also an option to hide this notch in the software. At back, glass is used which gives a premium build to this phone. The back is also protected by Corning Gorilla Glass. The build quality of this phone is really good.
The performance of this phone is really good. It is powered by Qualcomm's Snapdragon 845 chipset which is the top end chipset by Qualcomm this year. For better graphics there is Adreno 630 GPU so the phone will be able to handle all the graphic intensive tasks very smoothly. The performance of this phone will be really good. As it is powered by best android phone powered chipset.

 LG flagship phones are always famous for their camera quality so the legacy will be maintained with this phone as well. LG G7+ ThinQ is having a dual camera setup at back that is 16MP,f/1.6,30mm + 16MP,f/1.9,16mm. Here first one is a normal lens while other one is a wide angle lens. Wide angle lens is really helpful in capturing very cool wide angle pics. This camera supports Laser as well as phase detection autofocus for better focusing. Also there is OIS for better stabilization of camera. It can capture videos upto 2160p @30fps. It can only record slomo videos in 240fps which is a little bit disappointing. But for video recording there is a full fledged manual mode provided which is amazing and will be really loved by camera lovers.
On front there is an 8MP,f/1.9 lens for selfies. This camera also has portrait mode for background blur. This can capture videos upto 1080p @60fps.
User interface

 LG G7 ThinQ is powered by LG UX custom UI which is based on Android Oreo 8.0. User Interface is the thing for which LG phones are not famous for. Many of the users around the world think that LG UX is quite cumbersome. It seems to be little bit outdated. There are lot of customizations we can do. But the experience of the UI is good, it runs smooth. There are no lags and the performance is good. But LG is also really slow for it's software updates. So this device is promised Android P update but it will come really late if we see the previous record of LG.
LG presents this smartphone as a multimedia smartphone so the audio output of the phone should be really good. The phone is having just single speaker at the bottom, instead of going with stereo speaker setup. This has an echo chamber which helps in amplifying the speaker's sound when placed on a hard surface. So this is really cool as sound bounces back when it hits the hard surface and the sound amplify in this way. As it has a 3.5 mm jack, it has HI FI quad dac which really enhances the sound output when connected thorough a high quality headphone.

 LG G7+ comes with a 3000 mah battery. The battery life of the smartphone will be good because the chipset used on this is really power efficient. It comes with a fast charger within the box that is a 9V,1.9A charger. Also this phone supports wireless charging which is a good thing as most of the phones in this price generally don't have wireless charging. This comes with USB Type-C port for charging.

Other Features

LG G7+ ThinQ comes with IP68 rating so it is dustproof as well as waterproof. Mostly phones at this price doesn't come with any such certification. It comes with face recognition as well as fingerprint scanner for unlocking the phone. The phone comes in 128GB internal storage and 6GB of RAM so there won't be any RAM management issues in this smartphone. It also has all the sensors which is a good thing.

Final Conclusion

LG G7+ ThinQ is a really great smartphone at the price. It is priced at just 40000 INR or $570 which is pretty low for a flagship device. At this price it directly competes with OnePlus 6. OnePlus 6 is priced at 35000 INR for 6,64GB model and 40000 INR for 8,128GB model. If you want a true flagship from a reputed brand you can simply go for LG G7+ ThinQ.
