best battery saving apps for android
Battery saving is a land of snake oil and half solutions. It truly is difficult to find an application that actually saves you battery since most battery saver measures are manual, including turning the brightness on your screen down, turning down the frequency that apps sync data, and other tried and true methods. In most cases, you see bigger improvements when chip makers like Qualcomm, screen manufacturers like Samsung, and battery manufacturers improve battery efficiency of the hardware. However, there are a few apps that can help out too so let’s check out the best battery saver apps for Android.

GSam Battery Monitor (root or non-root)

Price: Free / $2.49

GSam Battery Monitor is another popular battery saver app. It won't do anything to save you battery life on its own. However, it can provide you with information about the apps draining your battery. You can use that information to improve your own battery life. It can show details on wakelocks, wake time, and even CPU and sensor data. It faced some difficulties with the latest versions of Android. However, there is a root companion that can deliver additional information if you have root. It's pretty good for what it is.

Servicely (root only)

Price: Free / Up to $13.99

Servicely is one of the better root-only battery saver apps. It works by stopping services that run in the background. It helps prevent rogue apps from going bananas and keeps them from syncing all the time. This is great for apps you like having, but you don't want syncing all the time. You may get a delay with stuff like notifications, though, so do use this tool carefully. This app works well with wakelock detectors as a potent one-two punch. It's highly configurable with enough options to make it work how you want. You can get the pro version as a $3.49 in-app purchase.

Wakelock Detector is one of the best battery saver apps. As the name implies, this app helps detect wakelocks. It can detect both partial and full wakelocks. You can also get a list of all the apps that are causing it. From there, you can take steps to uninstall the apps, find replacements, or use another app like Greenify or Servicely to put a stop to that nonsense. This is the one we'd recommend first to root users.

Other battery saving methods

Google is slowly closing the doors on Android when it comes to stuff like accessibility, developer tools, and the like. Thus, the really good battery saving apps are for root users only. Thankfully, there are some small tricks that improve battery life no matter what device you own. Here are some quick, simple tricks that do actually work:

  • Uninstall apps you don’t use – That way they don’t run in the background and consume battery life. This also increases your storage.
  • Lower your screen brightness – This is sometimes unavoidable in certain situations like direct sunlight. However, the lower your screen brightness is, the less energy your screen uses. Your screen is usually the top source of battery drain. This is also the only battery saving trick that works on LCD screens.
  • Use black themes, wallpapers, etc on OLED screens – Samsung, Google (with the Pixel 2 XL and Pixel 3 XL), LG (with the V30 and V40), and some others use some kind of OLED, POLED, or AMOLED display. OLED screens display black by shutting off individual pixels on the screen. Thus, using blacked out themes, wallpapers, and other elements allow portions of the screen to remain off at all times. After that, it’s simple math. The fewer pixels your phone has on, the less energy your display uses. It is a little difficult to find AMOLED friendly dark modes in apps. However, it is starting to catch on with more and more developers.
  • Don’t play games – Mobile games are notorious for their battery chugging capabilities. Those who need to stretch their battery life may want to wait to play games until they are near a charger or at home.
  • Use WiFi whenever possible – Cellular connectivity generally drains battery faster than WiFi. The less often you’re on your cellular network, the better. This has an added benefit of using less data, a boon for those with limited data plans.
  • Turn off connections you’re not using – We’re talking stuff like Bluetooth, your WiFi radio, etc. They drain battery if left on even when not in use. Those in a battery pinch can enable Airplane Mode and turn everything off. This doesn’t save nearly as much battery as it used to because the hardware is a lot more energy efficient than it used to be, but it can still help a little bit.
  • Use battery saving modes on your phone – Most manufacturers include battery saving modes that apps simply can’t replicate. They generally hurt functionality, though. It usually turns sync off, lowers your screen brightness, and some devices have battery modes that decrease CPU clock speeds for better battery savings. Thus, only use them when you don’t plan on using your phone much or if you’re really low on battery.
  • Don’t use vibration or haptic feedback – Both of these require a little vibration motor to turn on and cause vibration. The motor drains battery, obviously. Turn them both off if you can live without them or, at least, use them sparingly. It doesn’t seem like much, but if you get a lot of notifications or do a lot of typing, you’re asking that motor to run hundreds of times per day. It adds up.
  • Don’t use booster apps – They work by trying to kill processes that may consume battery. However, with the way Android works, those processes just open again shortly after they close. Thus, you have an app that runs in the background killing tasks that bring themselves back to life. This actually causes more battery drain in many cases. Don’t use them. They are garbage.
