1, if it is turned on 24 hours, three days is not too little to tell the truth. If your location itself is not very good, the time will be shorter. However, there are still alternative models according to your requirements.

2. At present, mainstream mobile phones are roughly divided into several categories, namely, bar, slider, full touch screen, flip cover and full keyboard. In view of the fact that I have changed countless mobile phones, but the slider has never been used, I dare not speak casually.

My mobile phone is basically based on Nokia, although many others have been used, but after all, Nokia is the most familiar, so it is only for Nokia's reference.

Okay, alternative model.

1, c5-00: The early stage of this phone 1, 000. It is not a high-end mobile phone, but it has many functions. Personally, I feel that girls look good in white. Highlight: Although this machine is a Saipan s60 smart machine, the cpu frequency is not low in Saipan, but the standby time is good. Call quality and other issues Nokia is a mature brand, there will be no problem, because it is a smart phone input method that can be installed casually, such as sogou and so on. . . .

2.e7 1 e72: This series of mobile phones is a full keyboard horizontal screen mobile phone. And smart. It is not a problem to install software such as input method, and the call quality is also ideal during standby.

3.5230 5800: This series is a full touch mobile phone, and the recommendation reason is similar to the above. However, these two models will have some discounts on standby time because they are equipped with the fifth edition of Saipan s60 on a full screen.

4. If standby time is strongly required, you don't need to consider Android or Symbian 3 or other full touch screen system models. After all, cpu power consumption is close to 1g or higher. . . . . But then again, mainstream brands seem to have waited too long, and there are more knockoffs.

5. I hope it helps. .
