During frequent business trips or long trips, the phone with the most powerful battery will become an indispensable friend of yours. The possibility of continuous operation without recharging is the main advantage of this class of devices. But at the same time, their functionality is minimal. In this article, X-treme models from Sigma mobile, P7 from Senseit and LionKing800 will be considered.
X-treme
The basic model of Sigma mobile cannot boast of phenomenal technical characteristics. But at the same time there are two points that distinguish the X-treme from other devices. Firstly, this is the phone with the most powerful battery that you can buy. Its capacity is 3600 mAh. In standby mode, it can take 30 days without recharging, according to the manufacturer. But during the conversation it will last for 13 hours. Secondly, this mobile phone is equipped with a housing with a high degree of protection. That is, it is resistant to dust and moisture.
The rest of its parameters are not distinguished by anything special. A regular screen with a diagonal of 1.8 inches. In this case, the display resolution is 240 pixels wide and 320 pixels long. 0.3MP VGA camera. It has 1.8 GB of internal memory, which can be increased with a
memory card up to 16 GB. Connectivity in the X-treme is implemented in the following ways: USB and Bluetooth.
P7
The second phone with the most powerful battery that can be found on sale Is the P7 from Senseit. They have much in common with the previous model. First of all, this is the battery capacity, which, as in the previous case, is all the same 3600 mAh. It is enough for a month of work in standby mode and for half a day of continuous conversation. Secondly, the case in it is in exactly the same design: it is protected from moisture and dust. But the screen is slightly smaller - only 1.77 inches, whose resolution is 128 pixels wide by 160 pixels high. A camera similar to the X-treme - all the same 0.3 megapixels. The built-in memory in this model is 200 MB larger than that of the analogue from Sigma mobile, and its 2 GB here. If necessary, it can be increased up to 16 GB using a microSD memory card. The set of communications in it is exactly the same as in the previous mobile phone - USB and Bluetooth.
LionKing800
LionKing800 is a unique development of a little-known Chinese company. This is the phone with the most powerful battery in the world. Its capacity is 16800 mAh. This capacity is enough for a year of work in standby mode and up to 5 days with continuous conversation. Other characteristics of it are no different. The screen of this phone is touch, the diagonal is 3.2 inches. In this case, the display resolution is 240 pixels wide and 320 pixels long. The amount of internal memory in
LionKing800 a few kilobytes, so you can not do without a memory card. It is equipped with 2 cameras. One of them is for video calls, and the second is for photos and videos. The set of communications in it is the same as in the previous two models.
The choice
LionKing800 has no analogues in capacity. Its price of $ 145 is justified. But this model has one significant drawback - it is impossible to buy today. Therefore, the choice is limited to the X-treme and P7. These are cell phones with a powerful 3600 mAh battery each. Their technical component is almost identical. But the price varies significantly. At P7, it is 160 USD. X-treme will cost you 110 USD, which makes it an optimal purchase. It is in terms of price / quality that it has no analogues.
