Industry insiders believe that although the basic protection functions of mobile phone security products are relatively complete, there are still deficiencies in anti-harassment, privacy protection and data protection, and there is still a large market space in the future. 2013 will be a key year for the acceleration of mobile cloud security, and major security vendors will continue to increase their investment in mobile cloud security solutions. At the same time, the products of many mobile phone security manufacturers adopt a free model, and at the same time that a certain user scale barrier has been formed, how to form a one-stop business model of "basic security underlying service + platform + content" will be the choice that security vendors need to choose in the future.

If the phone can't be charged, don't fix it, come and learn this trick.

The reason why the battery of Huawei mobile phone cannot be charged is as follows:

1. Check whether the charger is normal.

Usually when encountering a mobile phone that cannot be charged, the first thing to consider is whether the charger is normal, whether the charging cable is damaged, whether the charging head is faulty, and whether the contact is poor. If your own charger is damaged, try using a different charger to check if it can be charged.

2. Check whether there is a problem with the data cable, and the user replaces the new data cable to test whether it is charged normally 3. Check whether the charging hole of the mobile phone is damaged.

To rule out whether the charger is normal, then consider whether the charging hole is damaged. Check whether there are any foreign objects blocked in the charging hole and whether the metal contacts are damaged.

4. Consider whether the mobile phone battery is damaged.

Exclude both of the above cases. That's a problem with the phone's battery. If it is really a battery problem, then it is possible that the phone is over-discharged, causing the battery to sleep. It is recommended to take it to a mobile phone repair shop for repair.

Reason 1: The output voltage and power of the computer charging are not up to the standard charging voltage and power due to insufficient output voltage, which results in less and less charging, and will also have a certain impact on the hardware of the mobile phone;

Solution: Use the original charging head, or stop using the phone for a period of time, and wait for the charging to complete before using it.

Reason 2: Battery aging and failure capacity declines: lithium batteries are generally used now, and lithium batteries themselves have a certain service life (mainly in terms of the number of charging and discharging, normal use can reach about 500 times, and with the increase of the number of times, the capacity also decreases proportionally, and ordinary users can generally use it for about two years);

Solution: Since most of today's mobile phones use a non-removable battery design, you need to contact the repair point to replace the battery in this case.

Reason 3: Use of miscellaneous chargers: users often overcharge and overdischarge due to abnormal use, such as the use of miscellaneous mobile phone chargers;

Solution: Do not use cheap miscellaneous chargers, the cost of this kind of charger is limited, the imperfect protection circuit is easy to cause overcharging and charging bad batteries, try to use the original mobile phone direct charging is the best.
