It’s a good idea to know which types of apps to avoid installing on your Android phone if your goal is to reserve as much power as you can. The answer is pretty simple: any app that runs in the background and/or draws power at inconvenient times is not an app you’ll want to be installed on your Android phone.
Storage cleaning apps, RAM optimization apps, social media apps, and apps that claim to “save” battery may ultimately end up draining it faster due to the way Android app permissions work. Not to mention, such apps are usually loaded with advertisements that use even more electricity than you might’ve bargained for. Your phone may also include apps provided by the manufacturer which passively drain power without you ever knowing.
