How long Do You Charge To Reach 50%?

I made this post to find out how many times smartphone or cell phone users or phone takes to reach half of its life battery (sometimes called 50%).

I saw the extraordinary devices have all the time to load. some take approximately 4 hours 30 minutes for 90% charge, while some other phones can take only 90 minutes to get completely full. if the owner of a device that takes about 2 hours to reach 50%, then something is wrong with this device.

it will be a curse to connect your mobile phone for 4 hours, the most effective way to discover that 10%.

So how long can you take your mobile phone to get 50% of the load?
