Do you have enough power?

The best way to check the battery: 1) Turn off the phone, plug it in and charge it until it is fully charged. (It is best to charge continuously overnight to ensure maximum power. Remember not to turn on the phone before it is fully charged.) 2) Turn on the phone without unplugging the power source. 3) After entering the system, use the terminal, Root Explorer or other similar tools to delete the file /data/system/batterystats.bin. 4) Unplug the power supply and use the phone normally until it shuts down automatically. At this time, the battery still has remaining power. Wait for one to two minutes and then turn it on again to use up the remaining power. 5) At this time, the mobile phone has reacquired the current battery power information. 6) Fully charge the battery again when it is turned off. Without unplugging the power supply, turn it on and continue charging until the battery is fully charged. You can then start normal use. If you find that the standby time is obviously shortened after flashing, you can use this method once, and there will be no other effect if you use it multiple times. As we all know, Android phones are very popular now. Samsung, HTC, Huawei, ZTE and other brands have Android phones, but they all have a common problem, that is, the battery is not durable! (No way, all smartphones are like this) The following method can fully activate the battery performance and make the battery last longer! (Android phones rely on the system to allocate battery power, and it will record it. If the battery information recorded by the system is incomplete, even if the battery still has remaining power, the system record has already defaulted that it is out of power, and it will shut down! How sad...) After the battery has been used for a period of time, it is not as durable as when I first bought the phone. We know that Android phones will record your battery information in the system, so our batteries will become more and more fucked. After using 100% for a few minutes, it will drop to around 90%. In the past, there were many software and methods for calibrating the battery, and they were indeed effective. The battery was charged more fully than before. Using those methods to calibrate the battery was not the most thorough (treating the symptoms but not the root cause). This is how we calibrate the battery: Non-rooted mobile phone (without obtaining the highest permissions): 1. Keep the phone turned on and connect to the charger for charging (both USB and cable charging are available) 2. When the phone LED turns green, it means the battery is full. Unplug the phone from the charger. 3. Turn off the phone, then connect the charger to charge, and let the phone charge until the LED light turns green again. 4. Unplug the phone charger. 5. Turn on the phone, wait until the phone is turned on and completely enter the system, and then shut it down quickly. 6. Connect the charger to the turned off phone again, wait a few minutes and the LED light will turn green again. 7. Unplug the phone from the charger, turn it on and use it normally (PS: This method can also be used on other phones, and non-smart phones can also learn from it). Phones that have obtained root permissions (obtain the highest permissions): 1. Keep the phone turned on and connect the charger to charge. 2. When the phone's LED turns green, it means the battery is full. Unplug the phone from the charger. 3. Turn off the phone, then connect the charger to charge, and let the phone charge again until the LED light turns green. 4. Unplug the phone charger. 5. Turn on the phone, wait until the phone is turned on and fully enter the system, and then shut down quickly. 6. Connect the charger to the turned off phone again. Wait a few minutes and the LED light will turn green again. 7. Start the phone into recovery mode (press the return button and the power button at the same time to start) PS (take Samsung S5660 as an example, press the middle HONE button, and then press the power button, it will enter the RE mode in about 10 seconds), then select wipebatterystats (currently only Android phones are known to have this function) or use: 1. Turn on the phone, connect the charger until the indicator light turns green 2. Unplug the charger, turn off the phone, and connect the charger until the indicator light turns green 3. Unplug the charger, turn on the phone, enter the system, turn off the phone, and connect the charger until the indicator light turns green. 4. Unplug the charger, turn on the phone, go to wipebatterystatus in the advanced menu in recovery, and then restart. After following the above steps, the battery calibration is completed. It only takes 5 minutes longer than usual to charge, but the calibrated battery is obviously different from before. Before battery calibration, you will find that the battery will drop to about 93% after a little use when fully charged. After calibration, it can maintain 100% status for several hours before it starts to drop to 99%. In short, the battery after calibration will definitely surprise you.In addition, the effect of rooting the phone through the recovery program wipebatterystats is better, but it is not necessary. Note that battery calibration only needs to be performed once, and repeated attempts will not increase your battery activity. If your battery still does not improve after performing the above operations, it is very doubtful whether your battery is original. If it is not original, the effect will be average... {If you want to crack the authority of the engine oil, it is recommended to use Master Zhuo, which is a good helper for cracking the authority and flashing the phone) The following method is dedicated to those who love to flash the phone: If you are a flashing fanatic, don't miss this method! ! Friends who frequently flash their phones, frequently change the ROM (mobile phone version). Each version has different power consumption, so the battery information recorded by the system is also different. When you change to a new version, your battery information will not be changed (some oils show 60% of the battery before flashing, but it becomes 80% after flashing, so your battery uses 20% less power than before). However, the power consumption information of the new version of the battery will also be read, so it is easy to cause confusion in the battery record information and cannot achieve the expected results! ! Added: 1) The file /data/system/batterystats.bin is a variety of battery information including voltage recorded by the system. After deleting this file, the system will restart counting battery usage information. 2) The job of "Wipe battery status" in Recovery is to delete the file /data/system/batterystats.bin. 3) The reason why I selected this file instead of "Wipe battery status" when deleting Recovery in the Android system is because the charging indicator light in Recovery status is not on, and I think it is not in charging status at this time (please correct me if there are any mistakes in this regard). Because it requires a little power to enter Recovery, deleting the battery information file when the battery is not full will affect the reset effect. This method deletes all the recorded information of the battery, which is the same as restoring the phone to the factory. The purpose is to allow the system to re-record the information of the current battery of the phone (the battery must be saturated), so that the battery can reach its optimal state and the system can fully utilize the battery power! ! After the calibration is completed, it is best not to replace the battery. Although two batteries are good, the battery cannot be calibrated too frequently...
