Some tips about the right way to charge your phone

Some tips about the right way to charge your phone 1. Letting your phone go to 0% charge and then recharging it to 100%. It is definitely not a good option. If you do so you can damage the inside materials of the battery and can cause battery corrosion. 2. A fast charge can reduce your battery life.  It generates more heat than the normal charge which is bad for the battery.  It consumes more battery than it gives to your phone. 3. Using Random chargers -   It's not true that all the charges are the same. The best thing you could do to your phone is to provide it with the original charger. Other chargers may have different potentials that can damage your phone and also they don't include any protection from power surges. 4. Charging your phone in cafes or other public places.

Some unique and weird things about Japan, the land of the rising sun Japan is known as the land of the rising sun, but there are so many things that make it a whole other world. Get ready to explore! 1. Square watermelons  They were invented back in the 70s by a graphic designer to fit compactly in the fridge and be cut more easily. Japanese farmers grow them in special containers to get the shape. Since they are pretty expensive, people don't buy them as food, but rather as a decorative item. 2. Bizzare flavors of kit-kat  Chili pepper, wasabi, sweet potato, grilled corn, soybean, salt watermelon, mango, green tea - yes that's only a shortlist of the KitKat flavors you can try in Japan. Which one will you try? Let me know down in the comments. 3. Umbrella Parking Lot   Before going inside a building, you can park and lock your umbrella just like you do with your bike. Now you can be sure no one will take it and you won't make a puddle on the floor if your umbrella ...
