This process often fixes the battery reading. This is my personal experience.

7 Proven Ways To Increase Charging Speed

Turn On Airplane Mode

Airplane mode reduces battery use and supports charging. This may look like a small setting to you, but it is helpful.

Close Background Apps

Clear recent apps and close unnecessary apps. If possible, uninstall apps that you do not use.

Use Battery Saver Mode

When you turn on battery saver mode, the phone limits background apps, sync and notifications.

This reduces the load on the battery and charging speed becomes 10-15% faster. This is true.

Clean Charging Port

Dust can affect charging speed. Yes friend, it can make charging speed so slow that you cannot even imagine. Brother, I am telling you every thing so that your problem is fixed quickly, so you can fix your mobile problem at home.

Fig 2: Duplicate chargers cause slow charging + battery damage

Duplicate chargers are often the reason for slow charging. I also used a duplicate charger of my friend once. But that day I got so worried. I thought, why is my mobile having this kind of problem in just one day?

Install Software Update

Latest updates can improve battery optimization.

Android 14 and 15 have given an Adaptive Charging feature by Google. It charges slowly at night to protect battery health. Also, new updates limit background apps so the battery does not drain while charging. So always go to Settings > Software Update and check if there is any new update.

Monitor Battery Health

Old batteries charge slowly naturally.

After 1-2 years, battery capacity becomes less than 80%. If your mobile is 2 years old and you have to charge it 2-3 times a day, then friend I will advise you to change your mobile battery.

Mistakes That Cause Slow Charging

1. Using cheap charger damages both battery and charging.
2. Playing games while charging damages the battery.
3. Keeping it on charge all night reduces battery life.
4. Using damaged cable, the wire inside the cable gets cracked.
5. Ignoring overheating, putting it on charge whenever the mobile gets hot.

If you fix all these mistakes, then in my opinion 100% of the problem will be solved.

Is It Necessary to Buy a New Charger?

If your charger has become too old, then you should buy a new one.

First test the cable, clean the port, update software and close background apps. If the issue is still there, then consider the charger or battery.
