Take care of your phone and take care of your battery!

 

Quote

There are a lot of articles on the Internet on how to maintain your battery; but I don’t know why when I asked the people around me, they still have wrong impressions on batteries. Here Joey will simply and clearly list how to take care of batteries and hope that everybody can take good care of their phones; just follow these simple instructions.

 

Q: Should I charge the battery only when it is dead? Is it ok to have the charger connected even when there’s a lot of power remaining?

Quote

This is one of the most frequently asked questions: Is it ok to keep the charger connected to the phone and let the battery remain at 100% before I go to bed? Or should I charge it when the battery power is depleted?

 

Here’s the answer: Do not let the battery run out of power!
Do not be afraid of overcharge; only afraid of not charging!
Do not be afraid of overcharge; only afraid of not charging!
Do not be afraid of overcharge; only afraid of not charging!

 

Because this is too important, so as usual I repeated it three times. Many people think that it is not good to have the charger connected all the time, but the fact is that the lithium battery that mobile phone uses is not afraid of charging at all; on the contrary, it is bad for it to run out of power. If you always let the battery remain at a low power status, the battery life will be affected. Therefore, just remember the figure below:

Q: New batteries must be fully charged for 12 hours before use
 

Quote

This is also one of the most frequently asked questions; even some of the mobile communication stores will teach you this. But is it necessary?

 

No! This is not necessary! However doing so will not harm the battery either. Simply put: it makes no difference! It makes no difference whether the battery is fully charged for 12 hours before use; it’s ok if you want to do so, and it doesn’t matter if you don’t. This rumor started due to the NiMH and Nickel-cadmium battery usage habits in the past; only these two types of batteries must be fully charged for 12 hours before use. There are no differences with the lithium batteries used nowadays.

 

Q: Why do some people say do not overcharge mobile phones?

Quote

As previously mentioned, lithium batteries are not afraid of overcharging; only not charging. Therefore you will rather want to overcharge it than having the battery at low power status. But why are there many articles on the Internet that say do not have the charger connected all the time? What’s the reason behind this?

 

The answer is quite simple; although lithium batteries are not afraid of charging, but it is afraid of “heat”. Under many usage scenarios, having the charger connected all the time does indeed cause the battery to heat up (especially when you are playing games while charging); this causes damage to battery life. “Constantly charging” is not what causes damage to the battery; the “heat” generated from constantly charging is what causes the damage. If you simply charge it while you sleep, then there would be no problem; what you should avoid is heavy usage of the phone while charging, that’s why you should try to avoid such habits. Other things that should be avoided include placing your mobile phone on the dashboard of the car, exposing to directly sunlight, or placing it in high temperature environments.

Q: So what’s the right way to use the battery?

Quote

Avoid depleting battery life and prevent overheating while charging; do those give you headaches? Joey has some recommendations that you are refer to…

Truth is, mobile phone batteries are not as weak as people imagine; from personal experience and experience of people around me, most people change their mobile phone once every 2~3 years, right? The battery life of lithium battery is approximately three to five years; therefore I think you should not be too alarmed. Charge when needed and don’t get nervous and start to look for fans or turn on the air conditioner when the battery heats up a little. Just use it “normally” and let the battery remain under “normal circumstances”; then the battery consumption will not be as fast as your phone-changing frequency. Mobile phones are purchased to use, so there’s no need to get all nervous about it; ok?

  1. You can never let the battery overly discharged,
  2. If you use default charger, isn't any method or simply - isn't possible to over charging.
  3. Never isn't possible to get the battery 100% full.
  4. To sum up: You can not do anything, that the battery is maintained for longer. Also is very difficult to damage the battary, if you do not do it quite deliberately, breaking all rules, how to use it normally.

Of course, there is difference, what kind of accu You have, but in these days is mostly everywhere Lithium Batteries. It is difficult to find mobile device, in which would be used the magnesium-cadmium batteries today.
