Replace your battery
A number of things could go wrong with a battery. First up, it could have gotten damaged due to liquid or physical damage or has developed faults due to a number of issues. But perhaps the most obvious explanation is if the battery is old, it could be near its natural death since batteries have a specific life cycle to perform before going blind. This is why you need to gauge if the battery is charging at its maximum 100% or not. You can keep a track on the battery backup that would explain if it has degraded compared to the time when you used the phone for the first time that must give you an idea if the battery has degraded or not.
Replace the charger
Your charger is not just a fancy blob of the plastic box but a unit that transforms incoming current into the outgoing current as per the requirements of your smartphone. Also, the charger has a number of components involved and any damage to any of these components can have a resonating impact on its capability to charge the battery. If it is damaged somewhere, it might not be performing at its optimum capability thereby triggering battery draining problems. You can verify it simply by changing the charger that must give you a fair idea for sure.
Toggle Display settings
OLED displays consume battery greater than LCD and other display technologies. However, here’s a uniform method to toggle display settings that would relieve the battery of the stress causing it to constantly drain. First up is to reduce the brightness settings which you can do via Settings >> Display or simply by dragging the notification panel and drawing the brightness to low when you are not able to view the screen. Next, you also need to reduce the Keep Screen ON to a minute or so. Next step is to turn off Always-ON display and that must keep the battery healthy. Also, you need to avoid using videos or live wallpapers on the home screen as it consumes battery and having a photo reduces the battery consumption without any further ado.
Get rid of cache files
Next method is to get rid of cache files. To put things into context, cache files are useful but they get corrupted very easily and that is a problem. Viruses, malware, bugs are other foreign stimuli that cause the cache files to work adversely. Here’s how you can get rid of cache files.
Firstly, clearing cache partition is easy since you need to boot into the recovery mode and select ‘wipe cache partition’ and that’s it. The second method is to clear the app-level cache which you can access via Settings >> Apps >> Downloaded where you need to select apps individually and press the two buttons i.e. “Clear Data” and “Clear Cache” and repeat the same for all the other apps. Finally, the third step revolves around clearing storage cache that you can access via ‘Settings >> Storage >> Cache Memory’ and that must resolve the battery draining problems.
Update & Upgrade Apps
Outdated apps can ever be rewarding and the same goes for outdated firmware. You must feel that the phone is not performing at its optimum speed when bought compared to today when you are not able to keep the firmware updated unless you have a midrange or flagship smartphones introduced in the period of last one year or so. This is because Google updates firmware non-uniformly where it goes through several layers before reaching the user that could take months or sometimes, the phone doesn’t even support any update as well. In that case, you can either search for any firmware update or rollback to a previous firmware or install a custom ROM such as LineageOS.
On the other hand, to update apps, you can simply visit Google Play Store >> My apps and games. Here, a list of all the apps that are waiting for updates must appear that you must update. Next is to simply tap the ‘auto-update’ feature so that you don’t have to manually do it.
Restore factory
Finally, the method that must get you off the grid of battery draining problems if indeed it is caused due to faulty firmware or viruses, bugs, outdated apps and whatever related to software.
Step 01: Press the power button to turn it off.
Step 02: Now, press volume up and power button together using two fingers simultaneously and keep it pressed for a few moments.
Step 03: Next is to check if the screen shows an Android logo and that is when you can release the buttons.
Step 04: In recovery mode, touchscreen won’t work so you will be needing to press volume rockers to scroll around and power button to select an option.
Step 05: You need to select ‘wipe data/factory reset’ from amidst the menu that will set the ball in motion.
Step 06: Select ‘yes — delete all user data’ to give your consent to the procedure and wait for a few seconds to finish it.
Seek professional’ help
Unless you are able to fix the Haier battery draining problems, you need to visit a nearby authorized service center to get a resolution. This could mean a flash to the Android OS or repairing hardware components or replacing the battery if damaged but you can be assured that once you get the phone back, you will be relieved that the problem is long gone.
