ZTE Li3826T43P4h705949 Mobile phone battery common faults

1, the battery is not durable. There are many reasons why a mobile phone battery may lose power faster than usual. You can look at the battery consumption of each app in the settings. For some power-hungry users, if you are not used to it, don't leave them in the background of the phone. With the battery-optimized app, you can monitor and end some useless applications and processes to save power and extend battery life.

2, suddenly shut down. It is often found that the phone battery suddenly shuts down before the battery reaches zero. This is mainly because the electricity metering is not allowed.

The mobile phone automatically shuts down when the battery power has not been used up, in order to keep some of the memory and normal use, but the aging of the mobile phone increases the error of reaching the critical value.

3, feels very hot when charging. Nowadays, fast charging is popular, in fact, it is to charge the mobile phone with a large current. When charging, the energy conversion process will heat up. Under normal circumstances, there is no problem, and the general manufacturers have done rigorous testing.

iPhone mobile phone battery common faults

1, iPhone consumes power quickly. If you want to know why your phone is running fast, you can check it from the battery data built into iOS. The method is to enable "Settings" - "Battery". Next, you will list all the power consumption of the app. According to the data of 24 hours or the whole week to determine which app is silently consuming mobile phone power.

Of course, after discovering which apps are power-hungry monsters, the user can choose to delete the app directly, or to minimize the consumption of mobile phone resources by closing the background operation and location GPS service. The practice is to open "Settings" - "General" - "Background App Rearrangement", where you can disable any App completely.

In addition to the above, the network rumors that iOS's "HeySiri" function will also cause a lot of power consumption, because the iPhone must be on standby to hear the user's voice command, you must open Siri. To turn off the HeySiri function, go to "Settings" - "Siri" and turn off the "Listen HeySiri" option.

2, the iPhone suddenly shuts down. Excluding the normal power consumption and causing the shutdown, if the iPhone automatically shuts down when the power is normal, it is related to the system problem.

Therefore, it is best to recommend the purchase of an iPhone charger, you must use the original certified third-party brand charger, or directly buy Apple charger is also a solution.

Common fake battery identification method

1. The average Ni-cd battery is 500mAh or 600mAh, and the Ni-mh battery is only 800-900mAh. The capacity of the lithium-ion mobile phone battery is generally between 1300-1400mAh, so the time for the lithium battery to be fully charged is about 1.5 times that of a nickel-hydrogen battery is about 3.0 times that of a nickel-cadmium battery. If you find that the working hours of the lithium-ion mobile phone battery block you purchased are not advertised or as long as specified in the manual, it may be counterfeit.

2. If we find that the battery is extremely hot or smokes or even explodes during charging, the battery is definitely fake.

3. If a lithium-ion mobile phone battery block is faked with a cadmium-nickel or a hydrogen-hydrogen battery block, it must be composed of five single-cell batteries. The charging voltage of a single battery generally does not exceed 1.55V, and the total voltage of the battery block does not exceed 7.75V. When the total charging voltage of the battery block is lower than 8.0V, it may be a Ni-cd or Ni-mh battery.
