There can be several reasons why battery life decreases rapidly, but changing one setting can help extend your battery life to some extent.

Yes, it is possible. Simply avoid keeping your mobile data setting turned on all the time.

For most people, mobile data remains active on their phones. When this setting is enabled, your phone remains connected to cellular signals even when you are using Wi-Fi.

With this setting enabled, whenever you turn off Wi-Fi or move away from Wi-Fi signals, your phone immediately switches to cellular connectivity.

However, this also means that your phone continuously uses battery power to keep this feature running.

When you disable the mobile data setting, it can help prevent your phone from using additional battery power.

There is only one drawback: when you leave a Wi-Fi zone, it can take around 10 seconds for your phone to connect to the cellular network after you turn the setting back on.
