➡ More Megapixels mean Better Camera
Higher Megapixels only help to Capture Photos in Large Sizes or Resolutions, does not translate into better image quality. If you are looking for a phone with quality camera then you have to look at the sensor and aperture size rather than megapixel count.
➡ Bigger Battery Capacity will mean Better Battery Life
Bigger battery capacity usually means better battery life, but not always. For example, the Asus Zenfone 2 with 3,000mAh battery lasts less than a day, while the 2,500mAh battery of Micromax’s Yu Yureka lasts one and a half days on a single charge. Reason? The processor.
Bad apps that restart frequently, background processing, Wi-Fi turned on all the time, etc are a few other reasons why phones with big batteries don’t always give good battery backup.
➡ More Cores mean Better Performance
More cores don’t automatically mean better performance, since there are other factors that come into play, such as processor architecture, multi-threading support for apps etc.
For instance, a high-end quad-core Qualcomm smartphone almost always performs better than an octa-core Mediatek smartphone at the high end.
➡ Automatic Brightness, Live Wallpapers, Bluetooth Kills Battery Life
Turning on features automatic brightness, Bluetooth and live wallpapers do suck battery, but they certainly don’t kill it.
The actual change in battery life if you turn these features off is just 2% as per various tests.
➡ All your Data will be erased if there are Magnets near your Phone
Flash storage used in smartphones are of the SSD (solid state drive) type, and not magnetic hard drives. Therefore, the smartphone’s storage is completely immune to the effect of magnets.
