As we have published before, our new device Ulefone Gemini has packed a 3250mAh Sony li-polymer battery which will be sufficient enough to support one day use. But it often happens that there is only a few percentage of battery left while there is nowhere to recharge. Taking this case into consideration, we have offered a super saver mode on Ulefone Gemini. You can select it after holding the power key. Being activated, the super saver will close most apps as we as wifi, data connection, and other functions, only keeping the 2G network to enable phone call and message. In this mode, 10% energy will support standby for at least one day. With Ulefone Gemini, you will never miss important calls. Well, the presale of Ulefone Gemini will start on February 14 with USD40 discount and USD30 free gifts. Please get ready for the day!
