6 Best Android App For Saving Battery Life

1. Greenify

Download the App on the Google Store by clicking this Button
“Featured as Lifehacker’s Top 1 Utility in 2013 Best Android Apps (http://goo.gl/1VMwnE), Android Authority’s Top 3 Best Root Apps (http://goo.gl/g0L0qZ).

“Aggressive Doze” and “Doze on the Go” to maximize the battery saving on Android 6+, even without root! (details explained in settings)

Never should your phone or tablet become slower and battery hungrier after lots of apps installed. With Greenify, your device can run almost as smoothly and lastingly as it did the first day you had it!

Greenify help you identify and put the misbehaving apps into hibernation when you are not actively using them, to stop them from lagging your device or leeching the battery, in a unique way! They can do nothing without explicit launch by you or other apps, while still preserving full functionality when running in foreground.

Please report bugs in the XDA forum (http://goo.gl/ZuLDnE) or G+ community (http://goo.gl/MoszF).

Greenify NEVER EVER collects your personal data despite the capability of accessibility service, it just takes advantage of it to automate the hibernation procedure.

IMPORTANT: Greenifying an app implies that you are aware that all the background functionality (service, periodic task, event receiver, alarm, widget update, push message) of this app will become out of service during the hibernation except when you are using this app.

NEVER greenify alarm clock apps, instant messaging apps unless you don’t rely on them. Please do verify the impact of greenified apps on which you heavily rely.

Note: Greenify does need background running services for auto-hibernation to work. It is designed and implemented in extremely lightweight and nearly zero CPU and battery consumption.

=== PERMISSIONS ===

DEVICE ADMIN: This app uses administrator privilege to turn off the screen immediately after automated hibernation on non-root devices. This permission will be requested explicitly for your consent only if required.
DRAW OVER OTHER APP: To dim the screen during automatic hibernation when the screen is expected to be off.
DISABLE SCREEN LOCK & BIND ACCESSIBILITY SERVICE: For automatic hibernation to work on non-root devices.
GET ACCOUNTS & WRITE SYNC SETTINGS: Control the account sync of apps if its sync task is too frequent.

This app uses Accessibility services, to automate the hibernation procedure.

=== FAQ ===

* It seems that automatic hibernation is not working.
* Some of my greenified apps (e.g. Google Maps) seems not hibernating.
* I want to greenify system apps!
* De-greenified apps still got no push notification!

2. Naptime – the real battery saver

Download the App on the Google Store by clicking this Button
“This is the real battery saver. No placebo and dumb marketing shenanigans!
Naptime lowers your device’s power consumption while the display is off by empowering Android’s built-in doze power saving functionality. Faster idle means less power being consumed unecessarily. By default doze can take a while to kick in so Naptime just speeds-up that process automagically for you.

It can also automatically disable W-iFi, mobile data, location & bluetooth as soon as doze kicks in.

Experimental features such as automatic Android Battery Saver, Aggressive Doze timings, Aggressive Doze scheduling times and location detection.
Now you have profiles so you can load them up on demand based on your usage and accessible from Quick Tiles.

Most features work if you’re not rooted, but to have the full experience you’ll have to root your device.

F.A.Q.

Q: Rootless mode?
To use Naptime’s features without Root you need to grant it DUMP permission via ADB on your computer by executing this command:

adb -d shell pm grant com.franco.doze android.permission.DUMP

You also need to grant WRITE_SECURE_SETTINGS permission:

adb -d shell pm grant com.franco.doze android.permission.WRITE_SECURE_SETTINGS

After these two permissions are granted you’ll be able to use Naptime freely.
Q: I don’t receive notifications or my music streaming apps stop working after screen off. Please halp!
With ‘Aggressive Doze’ doze is being forced after you screen off. Doze is, currently, the most powerful battery saving mechanism on Android.

The following restrictions apply to your apps while in Doze:
· Only high-priority push notifications are delivered;
· Network access is suspended;
· The system ignores wake locks;
· Standard AlarmManager alarms are deferred to the next maintenance window:
· The system does not perform Wi-Fi scans;
· The system does not allow sync adapters to run;
· The system does not allow JobScheduler to run;

Apps like Gmail, which use normal-priority notifications, have them delivered during the maintenance window or when you wake up your device. This is standard behavior and can’t be changed
Although, you can choose apps to bypass doze. Go to Settings -> Battery -> overflow ->Battery optimization -> All apps -> Your app -> Don’t optimize
That’ll allow apps like Spotify to bypass the forced doze and actually work on screen off.

Q: What’s the ‘Sensors app whitelist’ feature?
It works together with the ‘Disable motion detection’ feature and allows you to choose up-to one app (sorry, Android limits us to only one app) to request sensor information even if you disable motion detection.
For example it allows apps, such as Google Fit, to query the accelerometer or gyroscope to count your steps.

Q: Why does my display, sometimes, blink once after screening on?
This might happen if you’re disabling the motion sensors. The reason for this is simple, for system brightness & auto-rotate settings to work after screening on they must be toggled on/off (otherwise they won’t work) and therefore it may blink (even if it’s only for a couple milliseconds).

Q: My fingerprint scanner doesn’t work when I disable the sensor motion detection!
Unfortunately not all devices will work fine when disabling motion sensor detection and in the process some other sensors & functionality might stop working. There’s nothing I can do about it and your only option is to not use that setting enabled. There’s also some weird compatibility with LG phones where the display doesn’t even turn on again if this setting is enabled.”

6. Accu​Battery

Download the App on the Google Store by clicking this Button
“🏆 Designed to keep your battery in the best shape you can – AndroidHeadlines

Accu​Battery protects battery health, displays battery usage information, and measures battery capacity (mAh) based on science.

❤ BATTERY HEALTH

Batteries have a limited lifespan. Every time you charge your device, it wears out the battery, lowering its total capacity. Scientific research shows that battery lifespan can be extended up to 200%, when you charge your device to only 80%.

– Use our charge alarm to prolong your battery lifespan.
– Discover how much battery wear was endured during your charge session.

📊 BATTERY USE

Accu​Battery measures the actual battery usage using information from the battery charge controller. Battery usage per app is determined by combining these measurements with information on which app is in the foreground. Android calculates battery usage using pre-baked profiles that device manufacturers provide, like how much power the CPU uses. In practice however, these numbers tend to be highly inaccurate.

– Monitor how much battery your device is using
– Know how long you can use your device when it’s active or in standby mode
– Find out how much power each app uses.
– Check how often your device gets woken up from deep sleep.

🔌 CHARGE SPEED

Use Accu​Battery to find the fastest charger and USB cable for your device. Measure the charging current (in mA) to find out!

– Check how fast your device is charging when the screen is on or off.
– Know how long it takes to charge your phone and when it’s finished.

HIGHLIGHTS

– Measure real battery capacity (in mAh).
– Use the charge alarm to prolong battery lifespan.
– See how much wear your battery sustains with each charge session.
– Look up the discharge speed and battery consumption per app.
– Remaining charge time – know how long it takes before your battery is charged.
– Remaining use time – know when you will run out of battery.
– Screen on or screen off estimations.
– Check the percentage of deep sleep, when the device is in standby mode.
– Ongoing notification for real time battery statistics at a glance.

🏆 PRO FEATURES

– Use Dark and AMOLED black themes to save energy.
– Access to historical sessions older than 1 day.
– Detailed battery statistics in notification.
– No ads

We’re a small, independent app developer with a focus on quality and passion for battery statistics. AccuBattery doesn’t require access to privacy-sensitive information and doesn’t make false claims. If you like the way we work, support us by upgrading to the Pro version.
