"It's all about battery"

Reviewed by / Nov 28, 2014

A battery usage management app

Although many devices come with options to check out battery usage and change your settings, these options use to be in different places of the user interface, so you have to tap a few times here and a few more there. Battery Doctor tries to save time unifying all known options regarding battery in a single, free, without ads app. In addition, it gives useful tips to regulate your battery expense and prolong your battery life and duration. It doesn't work as an automated task killer, in case you were wondering it (basicly because tasks killers use to drain battery instead of extending it). However, you can check which apps use more battery and stop running them through Battery Doctor.

As you can easily read all included features in its developer's description (KsMobile), we'll try to be straightforward: once you install this app you will get an icon on your desktop, though you can later place a 4x1 widget there if you want to have all settings at your fingertips.

Through this icon you will get access to easily understandable stats about your battery usage and, here's the best part of it, a link to every modifiable setting. Thus, below the estimated battery time left there are not only links to wifi, screen settings and so on, but also how many estimated time they will take. If you don't want to bother about everything, there are three preset modes to make your life easier.

Other great options allow to do a breakdown of battery usage within a time range, know if your charging habits are the best for your device and customize every option this app brings. Everything packed in one of the best user interfaces we have seen so far, so you can easy and smoothly modify your settings on the go. Lastly, battery left is always shown as a percentage at the notification bar, instead of subjective green battery icons. We could only ask, as there's no harm in it, for some skins or customization options.

If you haven't already a battery app, here's what you are looking for. And if you already have one, we're pretty sure you will like to check this out and compare. Absolutely recommended.

Q: Can Battery Doctor save power and extend battery life?
A: Yes!
Tap the circle at the home screen (Save Power) to kill power hog apps that are not currently in use to improve battery life.
Run our app while charging to let Battery Doctor manage the process with its Unique 3 Stage Charging system that ensures a longer battery life.
Use the "Task Killer" widget to optimize your power consumption conveniently

Q: What is a full charge and why does it matter?
A: Plug in your phone when the battery has about 20% remaining and continue to charge until Battery Doctor tells you the 3rd stage of trickle charging is complete. Do not overcharge by keeping your device plugged in nor undercharge by charging in short bursts whenever convenient.

Q: How does "Saving Mode" work?
A: "Saving Mode" is an extreme setting that shuts down all non-essential functions of your phone with exception of making phone calls and sending/receiving text messages. WiFi, Data, GPS, etc will all be shut down to ensure battery life and defend your juice.

Q: How do I set up the widgets?
A: The "Task Killer" widget will automatically appear on your home screen with installation. The other widget that monitors WiFi/GPS/etc can be installed just as any other widget on your device would be set up.
