Why Does My Phone Get Low Battery Easily. Remove the mobile malware to stop your phone from overheating. Also you can backup your phone then factory resets the device if the battery still drains fast it is the battery issue if not it maybe the apps you have installed.

So before you decide to replace the battery of your iPhone try to update all the apps on your iPhone. The firmware installed can be corrupted causing a power failure. Turn off Wi-Fi or change another cellular network.
Network coverage is much better than it used to be but you still get the odd dead spot.
My phone is doing this too. For example battery charged fully overnight battery meter at 100 I send a text message 10 minutes later 80 make a 5 minute phone call down to 50 then scroll the internet for 5 seconds and the battery power less than 20 low power mode option pops up. The fundamental reason is that the life cycle of the mobile phone chip will follow. Change a new and stable Wireless or cellular connection.
