After purchasing ASUS ZENFONE 3 ZE552KL MODEL (64 GB/4 GB) in September 2016, I am still in dilemma because of the increasing battery issues. The phone's battery is just 3000mAh !!! With so many specs, only 3000mAh!!?? But still that should work fine, unfortunately it isn't. The battery drains quickly from 100% to 84% in half an hour!!! I am seriously regretting purchasing ZENFONE 3. I hope Asus sends out a good and nice update for this issue in ZENFONE 3 as this should had been corrected by changing hardware not software.

Hi Rishi,

Please follow the below steps

1. Lower screen brightness

An overly bright screen consumes more power and can be harmful to the eye. To adjust brightness, swipe down from the notification bar twice and use the slider. Extend your battery life, and protect your eyes while doing so!

2. Shorten screen timeout time.
To squeeze more juice out of your battery, you can shorten the screen timeout time so that your phone goes into sleep mode faster. Try changing the time from the default 1 minute to 15 seconds.
To change this setting, tap Settings > Display > Sleep.
To change Cover View screen timeout time, go to Settings > ASUS Cover > Automatic sleep.

3. Trim unnecessary background apps.
Prevent unnecessary apps you don't need from running in the background and consuming your battery by using Auto-start Manager. Tap Auto-start Manager to select apps you want to discontinue from running.

4. Use Smart-saving Mode .
ZenFone 2 has many extremely useful battery modes, one of which is Smart-saving mode. It provides extra toggles for brightness, a feature that turns off internet, and an Extend Standby feature that lowers battery consumption by efficiently managing your push notifications when your phone is in sleep mode.
Tap Settings > Power management > Power Saver > Battery Modes > Smart-saving mode.

5. Tap Boost from Quick Settings.
Have you ever wished for a single button that solves all your problems? When you tap Boost, not only does it make your phone faster, but it also lowers battery consumption. Swipe down from the notification bar twice to find the Boost button.

6. Choose Wi-Fi over 3G/4G Data.
Using Wi-Fi instead of a data connection will use less battery because your phone doesn't need to constantly search for the network.
To turn on Wi-Fi, swipe down from the notification bar twice and tap the Wi-Fi icon.

7. Turn off Location Services, Bluetooth, and NFC.
Don't be lazy! Turning off these services when you're not using them can extend your battery life. To turn these services off, swipe down from the notification bar twice and tap the Location, Bluetooth, or NFC icon.

8. Set up an Auto-switch mode schedule.
You can't be using your phone all the time! Set up a time interval in Auto-switch mode to automatically switch to a lower battery consumption power mode when you're not using it. To do this, tap Settings > Power management > Power Saver > Auto-switch mode. After enabling this feature and choosing your starting and ending times, we recommend setting it to change to Ultra-saving mode (the default).

Last but not least, don't forget to pick up a ZenPower (From select resellers or at http://store.asus.com/us if located in North America) for all your charging needs when you're on-the-go! Fast and convenient charging available at your fingertips, whenever, wherever.

We recommend to always factory reset the device after you update the FOTA

Try and update your phone to Android 7 which Asus has recently rolling out and after update do one time factory reset and then start using it. Your problem has to do something with battery calibration.After reset if still problem remains then try and calibrate the battery.

Hi Rishi,

FOTA means firmware on the air. It means the updates which you receive on your device are called FOTA.

Factory reset is recommended so that the firmware which is installed runs very smooth and the bugs are cleaned.

Let us know if you have performed factory reset on your device.

That's really great. But my Zenfone 3 is performing just the same (average) after Nougat update. I hope in the new update there might be some changes. And it's a request to the ASUS update team to please check and bring out better update for Zenfone 3 regarding battery issues. (It would have been much better if the hardware was up to the mark, software is ok by the way)
