Battery draining is the most widely claimed issue among the smartphone users, especially when it comes to an Android smartphone. Those of you who are using such handsets must be experiencing this problem. While these days, companies are focusing on offering high-density battery packs on their handset, thus installing larger capacity in their battery packs. But unfortunately, not all companies are doing that, and it always doesn’t mean good battery life if the battery capacity is larger. So, what other options do you have to fix this problem if your smartphone isn’t providing good battery life.

Well, before we teach you how to check battery draining apps on your smartphone, you must learn how to access the battery screen and moreover what does that all hardware and system services shown in the battery screen section mean. That is how you would be finally prepared to fix the battery problem on your device.

What is the battery screen?

Battery screen showcases the battery usage since the last full charge. This will all vary on different devices as the system level interface is customized among many handsets. So, if you’re a stock Android user, then you’ll see different options under the battery section. But they are more or less similarly interpreted. So, yeah, follow the instructions carefully ad wisely.

Note that the demos you’ll see are been given on a Samsung TouchWiz UI.

How to get to Battery Screen and Check Apps Draining your Smartphone?

Opening the battery screen is quite simple; just tap on the Settings app from your app drawer and then scroll down to tap on the Battery option. Or maybe you can customize the Quick Settings to showcase Battery icon on top. So, that way you could quickly go to battery screen. Note that the battery screen will only showcase the battery usage since the last full charge. Now if you’ve just recently charged your device, well, you’re going to have to wait until at least 50% battery is down. Only then, you’ll know what all apps are draining the power on your smartphone.

Thus, you can later reduce the usage of those apps. Moreover, you could also see exactly how much mAh unit the app consumed since the last charge. Now you know how to check for the battery draining apps on your smartphone. But that is not it; there are more things that you see below would help you in preventing quick battery loss on your device. Check them out.

How to Get more Battery Screen Statistics using Third-party Apps?

After introducing the Android 4.4 KitKat, Google basically removed the permission where Android app could request the BATTERY_STATS function to access more information regarding the battery usage. For instance, you could view data about wakelocks, which would help any Android power user who is on the hunt for better battery life. One could as well view battery usage for certain periods of time that was not displayed in the Battery screen. Though, you could still use third party apps like Better Battery Stats, if your device is rooted. While without rooting on couldn’t do anything regarding battery stats, as you’d be stuck with limited data.

Prevent Unnecessary Hardware and System Services from Running

Improving battery life isn’t just being about finding out apps draining your smartphone of the power, but also about identifying what all hardware and system services that are unnecessarily running on your device. That’s why preventing them is also a job that needs to be done by its users. It’s a self-explanatory that apps use battery power when you use them, as well as they may run in the background. But here are some non-app items that you should monitor too.

Note that you’ll see computed power use for each item listed below in mAh units.

  • Screen: This is the main source of a power user, as when the display is ON, the screen and backlight use the power. It will always need some power when the display is ON, all you can do is reduce the brightness levels and configure the system to turn OFF the display when you’re not using it.
  • Android system: It represents that power used by things like Settings app itself, as well as input devices and other variety of system services. You should make it use less battery power by enabling the battery saver mode if the battery percentage is close to being low. That mode you’d find on the stock Android while talking about the TouchWiz UI on any Samsung device, you will see power saving mode. That can be turned ON if you need the battery life to last longer than usual. Moreover, you can restrict all background data from in the power saving mode.
  • Android OS: Regardless of the name, Android Operating System is separate from Android system. This item accounts for all the battery power used by the underlying Android operating system. It manages your running processes, interfaces with the hardware and does many low-power required, but important stuff.
  • Cell Standby: This shows up how much time your device was connected to a network and how much percentage of that battery period it was down, if it was. Note that if you have a weak cellular signal then it could result in higher power usage, and that’s why sometimes network operators are to be blamed for bad battery life.
  • Wi-Fi: The item shows how much power is used by Wi-Fi Radio on your device. We don’t generally browse through the internet every few seconds, unless you have nomophobia. Since it will always use power when you’re connected to Wi-Fi. So, it’s recommended that you switch it off when you’re not using Wi-Fi, because your Wi-Fi Radio would be using the power from the device battery. Also in instances like if you’re on-the-go, then you might be connected to mobile data. In that case, you should switch off the Wi-Fi as well.
  • Google Services: It includes services like Google Play Services, Google account manager, Google backup framework and backup transport. These are just another package of services being used by Android smartphones. The only way to reduce their impact on the battery life is to switch ON the battery saver mode.
  • Users: Setting up different users account is something that would be helpful in understanding how much usage have to be contributed by that account user. This is quite suitable for the large screen devices like tablet, because unlike smartphones, tablets are shared within friends and family members.
  • Idle: You should note that the Android device uses some amount of power even if it’s completely in an idle state. It may be low- power consumption, but the point is that you should know, even in the idle state, there is some battery usage, which can’t be prevented, because it is a need for a device; if you want quick access to even the basic features of it.

So, you saw where is the battery power went on the battery screen, but its up to you to do something with that information. Despite Google limiting access to advanced battery information, the current battery screen should be sufficient to understand your behavior pattern and take decisions to prolong the battery life on your smartphone.
