Huawei U8860 running memory issues

The running program is not turned off, so the memory usage is increasing. Less than 99% doesn't affect the speed much. Android's subprogram exit is not as straightforward as Windows's. So after many programs are opened, they are not displayed, but they will run in the background.

These software are registered in the system,In the boot,Connect to the Internet,Mount SD card,Come**,And so on, the system may open these software,And now there is no way to prevent these software from running automatically,If you feel that the machine is stuck,You can only uninstall the software that runs automatically。 Your machine is running out of RAM, and the software is installed in the ROM, which has no absolute relationship with how much software you have installed.

You can uninstall some of the system's built-in software through root, but generally speaking, the system's built-in software data is very likely to be shared by other applications, and you may uninstall some system software that may cause other applications to not work. So what can be unloaded and what can't be unloaded, first figure it out and then figure it out.

The other ones you said that you didn't open still have to run so big, because the phone itself has to run things like **thin, Android system, security guard, and other necessary software for the system. There's no way you can stop that. If it's a new phone, some software like the junk software that comes with the phone can be solved by rooting.

As for root, you have to change recovery first. Flash from recovery to the already rooted system.

Support 8G RAM Up to 32G memory card expandable.

In the tank! Smartphones generally support cards with a capacity of more than 8G.

Supported! It can go up to 32GB

It is recommended to back up the relevant data, then restore the factory settings, and then reinstall the relevant software and games. The installation directory is specified as the memory card, do not directly install it on the mobile phone memory card, the memory card capacity is limited. You can also adjust the ratio of the system part of the memory card to the storage part, which can solve the problem for a while, but if you often change games and reinstall other things, the memory card will definitely not be enough.

Under the normal situation of the system, it is recommended to back up frequently, and if you encounter problems, you can "one-click recovery" to reduce many troubles.

Go to Android and ask, there are a lot of heroes out there who can give you the answer. You can register for a free number.

Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process. Not only in theory, but in my own practice, it is best to use the standard method of charging this "natural activation" from the beginning.

For the "activation" of lithium batteries, many sayings are: the charging time must exceed 12 hours, and it must be repeated three times in order to activate the battery. This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of nickel batteries (such as nickel-cadmium and nickel-metal hydride).

So this statement can be said to be misinformation from the beginning. There is a very big difference between the charging and discharging characteristics of lithium batteries and nickel batteries, and it can be very clear that all the serious formal technical materials I have consulted emphasize that overcharging and over-discharging can cause great harm to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours.

In general, the charging method introduced in the manual of the mobile phone is the standard charging method suitable for the mobile phone.

In addition, the mobile phone or charger with lithium battery will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours as a nickel electric charger. That is to say, if your lithium battery is fully charged, it will also be white charged when placed on the charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality is foolproof, so your battery will be on the verge of danger for a long time.

This is another reason why we oppose long charging.

In addition, on some mobile phones, if you do not remove the charger after charging for a certain period of time, the system will not only not stop charging, but will also start a discharge-charge cycle. Perhaps the manufacturers of this practice have their own agendas, but it is obviously not good for the life of the battery and mobile phone charger. At the same time, long charging takes a long time, often at night, and in the case of China's power grid, the voltage at night in many places is relatively high, and the fluctuation is large.

As mentioned earlier, lithium batteries are very delicate, and they are much less resistant to fluctuations than nickel electricity in terms of charging and discharging, so this brings additional dangers.

In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for over-discharge, and over-discharge is for lithium batteries.

See if the battery is marked as a lithium battery or lion, if so, you don't need to charge it for so long, just use up the remaining power for the first time and then charge it normally.

Now the battery doesn't need to be charged for 12 hours, just have enough.
