Myth 1 – More mAH means more battery life
Say a car weighing 1000 kgs and having 100bhp of power is capable of delivering a mileage of 25kmpl. The same car will give lesser mileage if say you put another 500 kgs into it and will give more mileage if you reduce the weight say by removing the backseat for example. Similarly, the mileage will change based on your driving style as well. This is what happens in smartphone battery life as well. The mileage of a car can be related to the battery life of a phone.
A power user will get lesser battery life from a smartphone than a person who uses it just for calls, texting and the occasional browsing. Similarly even if you have 2 phones that are powered by say 3000 mAH batteries, their battery life will depend on the screen size and resolution as well. So a 5.5″ 1080p smartphone with 3000 mAH battery might give better battery life than a 5.5″ 1440p smartphone with 3100 mAH capacity. However that isn’t certain though as apart from the hardware specs, software optimisation plays a key role in a phone’s battery life.
Myth 2 – More Megapixels gives better image quality
The Megapixel game was something that maufacturers started when Digital Cameras were invented. Back then, the resolution was so low on cameras that an increase in resolution would be so apparent and would automatically make a big difference in image quality. However nowadays, Megapixels have transcended the point where adding a few Megapixels won’t really show you much of a difference unless you’re printing out onto a really big canvas or zoom into the picture and examine it carefully.
The image quality depends on the sensor size,lens quality and the iso capablities, also the ISP of your mobile processor,etc.
So phones with large sensor size with good lens quality and good processors give better picture .Other features like the optical image stabilization,etc also give better image quality which are found on the premium phones.
Myth 3 – Android Phones are more prone to Malware and other Viruses.
This is something that has some truth to it. If you are downloading apk applications from 3rd party sources there are high chances of your phone to get attacked by a virus.You can still install application using this method by checking the box that allows installation of apps from 3rd party sources. However, you should do it only if you are 100% sure that the app is legit and hasn’t been tampered with. Many apps may seem perfectly normal but have been tampered with and malicious software is often bundled along with such applications. It is also quite hard to trace such software as they are often hidden and you won’t really know unless there are signs that indicate the presence of malware. There need not be signs of malware present for sure but they could show up.
Signs could be anything from high data usage to high phone bills or even bad battery life. One way of preventing this is by using the Play Store to download and install apps whenever possible instead of using 3rd party websites or sources. There has been cases where some applications from the playstore have some virus but google or apple have taken them off immediately. Best option is to download these apps by looking at the ratings. So if you are downloading an app directly from the Play Store then it should be as safe as iOS or Windows Phone.
Myth 4 – More CPU cores means better performance
This is something that is similar to both the camera as well as battery life aspects that we mentioned earlier. It is not necessary that a processor will perform better than the other simply because it has more cores. There are a lot of factors that decide the performance a processor than just the number of cores or even clock speed alone. A perfect example of this would be to compare the performance of the Apple iPhone 6S or 6S Plus to the Samsung Galaxy S6 edge or the Note5. Both Apple phones are powered by Apple A9 chipsets that are dual-core while the Samsung devices are powered by octa-core Exynos chipsets. Here the number of cores are more in case of samsung but the apple chipset performs better. Instead, you should be looking at the memory bandwidth, latency and the ability to execute threads in an efficient manner. So even if the number of threads are less, the processor can perform better if the per thread performance is higher.
Myth 5 – One should only use the charger that came bundled with the phone
It is true that your best bet to charge your smartphone is to use the charger and cable that comes bundled in the box. The manufacturer knows what charger your device needs and bundles an appropriate charger. But is it fine to buy a 3rd party charger and use it instead of the original? Well, that depends on the chargers specifications. It is not the fact that the charger is a 3rd party one that causes issues but the power rating that makes the difference. If you purchase a charger that has the same power rating as the charger that it came with or one that matches the phones requirement then there is no reason why they can’t use that instead of the charger that came with it. So you don’t necessarily have to use the original charger itself.If your phone comes with a 1.5A charger you can use another charger that comes with same power rating.But is you are using a charger of 2.0A which is more than the original 1.5A it may have some bad effects on the battery.

Let me provide you some troubleshooting steps so you can diagnose your problem yourself instead of visiting to the service center. Step (1):Perform Battery Optimisation. Settings > Select Device Maintenance/Device Care > Optimize > Optimize all options like Battery, Storage and Memory. Step(2):Turn off Bluetooth, Wi-Fi, mobile hotspot, NFC, etc a). Swipe down on the home screen to open the notification panel. b). Tap on Bluetooth, Location/GPS, Wi-Fi, Mobile hotspot, NFC, etc. to turn off. Step (3):Kindly check whether the mobile network fluctuates frequently or network signal is low in your area. In both cases, the battery will drain considerably fast. Step(4):Reduce display brightness level. a). Swipe down on the home screen to open the notification panel. b). Turn on the Auto-brightness option if available. Step(5):Adjust screen timeout settings. Go to Settings > Display > Screen timeout > minimum screen timeout. Step(6):Update apps. Kindly check which application is or interface is using more battery from device care. And try to update the app or avoid using that app. Step (7):Close background running apps. Tap on recent key and close the background running application. Step(8):Turn off auto-sync of e-mails, app data, etc. a). Swipe down on the home screen to open the notification panel. b). Turn off the auto-sync option. Step(9):Check device in safe mode: Power off the device > Press and hold the Power key for one or two seconds to turn on the device > When the Samsung logo appears, press and hold the Volume down key. Exit safe mode: Restart the device. Step(10): Try your device in safe mode. As you were facing battery drainage issue in your device, I have provided you some basic trouble shooting steps and your concern has been resolved. "If the problem is solved click the three dots & click solution".
