Description for NOKIA HQ-50N battery:
1. Try to use the original charger. Compared with the original charger, the non-original charger has a certain gap between the output current and the voltage. The long-term use of the non-original charger can not only reduce the service life of the mobile phone battery, but also cause the battery of the mobile phone to explode and catch fire.
2. Lithium-ion batteries should be protected from full discharge during use (use a black screen to power down).
3. Do not place the phone in a high temperature environment. When the mobile phone is exposed to the sun for a long time, it will cause the battery temperature to suddenly increase or even explode.
4. should try to keep the phone away from the water source, in case the battery is short-circuited by moisture.
5. If the battery has abnormal conditions such as drum belly and damaged casing, stop using it immediately and replace it with a new one.
How to reduce cell phone radiation ?
1. When the mobile phone is called out, it is best to keep the mobile phone away from the head to avoid radiation on the head when the mobile phone emits more power.
2. Minimize the time each time you use your phone and the number of times you use your phone every day. When it is necessary to talk for a long time, it is more scientific to alternate between left and right ears or to use headphones.
3. When the mobile phone signal becomes weak, the mobile phone will automatically increase the transmitting power of the electromagnetic wave. At this time, do not put your ear close to the mobile phone.
4. do not pick up the phone in the corner, the signal coverage in the corner of the building is relatively poor, so it will increase the radiation power of the phone to a certain extent. For the same reason, when you are in a small, enclosed environment such as an elevator, you should avoid making calls.
5. Do not walk around when you touch the mobile phone. Frequent moving positions will cause the strength of the received signal to fluctuate, causing unnecessary short-time high-power transmission.
