Why does the battery charge less and less

The more you charge the less power the reason:
1. Insufficient output voltage. Computer charging output voltage and power does not reach the standard charging voltage and power, the result is that the more you charge less and less, but also on the phone hardware has a certain impact; do not use cheap miscellaneous chargers, the cost of such chargers is limited by the imperfect protection circuit is easy to cause over-charging charging bad electricity also, try to use the phone's original charger.
2. Part of the non-original charging head output voltage and power can not reach the standard charging voltage and power. When using unofficial chargers, data cables or cell phones connected to the computer JSB charging, the charging amount may be less than the power consumption of the phone, resulting in charging more and more charging less and less. It is recommended that you use the official recommended charger and data cable to charge your phone.
3. There is a foreign object in the data port or charging socket, or the port is loose with poor contact. Please make sure that the data cable port or charging socket of your phone has foreign objects or loose contact. Please make sure that the charging port is clean and the port connection is stable before charging your phone.
4. Battery aging failure capacity decline. Now generally use the album battery, hammer battery itself has a certain service life, hammer battery life is mainly based on the number of charge and discharge count, normal use up to 500 times or so, with the increase in the number of times the capacity of the proportional decline, if you encounter the battery aging affects the normal use of the battery replacement is recommended in a timely manner.
5. When charging the phone to run a high power consumption program. Please make sure that your phone is running a high power consumption program when charging. Running a high power consumption program when charging (e.g. shooting pots, videos, games, etc.) will easily lead to less and less charging.
6. Network signal problem. The old SIM card is bound to wear a lot because of years of use, and worn SIM card in the signal reception will have certain problems, signal reception problems will lead to the phone body. Often in the state of the network search, thus causing the battery to intensify the power consumption, and ultimately manifested in the battery is not durable, so that the appearance of more and more charging less and less power!
7. Mobile phone system software failure caused by the phone fails to accurately identify the current charging state, the actual battery power has been full, but the battery power display is not charged, you can restart the phone and then try to charge.
