Another important aspect worth covering is the battery life associated with the OUKITEL K4000 is its battery life. The 4000mAh rated battery is one of the most powerful ones in all the smart phones out there in this range. When your device is left with a scarce 14% of power, you get an auto reminder about whether you intend to turn on the power saving mode.
In the process which follows, the browsers, the mobile data as well as the wi-fi get disconnected in order to save power. When on power saving mode user can’t be afraid about battery because it lasts longer than other smartphones.
The BAK high density lithium-ion battery thus uses means of low charging voltage as well as reduced voltage conversion. This ensures that the overheating is regulated.
