[Nexus 6P Q&A, Help & Troubleshooting] sleekstrike:
So I just finished chatting with Google support person and asked them to raise a bug for this but they insist that I keep my phone in safe mode for at least a day and do a factory data reset before escalating this issue.

Here's the email that I got:

Hi sleekstrike,

Thank you for contacting Google Support Team.

As per our chat conversation, I'm sending you this followup email. Most phone and tablet batteries will drain quickly as the device is used more often or more intensively. If you feel your battery is draining too quickly, we need to determine if this is due to normal usage or due to a faulty battery. Below are some steps and tips that may help determine and resolve the issue.

Step 1: Restart your device.

Restarting your phone will clear temporary files and may resolve any app-related issues.

Hold the Power button until a menu appears prompting you to power down the device. When the device powers off completely, press and hold the Power button until your device powers on again. Step 2: Check for system updates for your device.

Downloading and installing system updates for your device can help prevent and resolve issues with your device.

Go to "Settings" > scroll down to "System" > touch About phone (or tablet) > touch System updates. If a system update is available, download it. Step 3: Check for apps updates on the Play Store.

Downloading and installing available app updates will ensure that the app is working as intended, which includes fixes for bugs and issues on previous versions.

Open the Google Play Store app. Touch the Play Store icon > touch My Apps to view your downloaded apps. Apps with available updates are labeled "Update." It's recommended that you select Update All, but you can individually choose which apps you want to update. Step 4: Settings adjustments and other actions.

a) Use the Recent Apps button to close unused apps that may still be running.

The Recent Apps button is the third touch button at the bottom of your device that looks like two rectangles on top of each other. When you touch the Recent Apps button, you can swipe left or right on an app to dismiss it. Some Android users are not aware that apps on the Recent Apps list are running in the background and may be contributing to memory and battery consumption. b) Temporarily turn off features not in use.

Location services and GPS: Settings > Location access > Turn off access to your location. Bluetooth: Settings > Wireless & networks > Slide the Bluetooth switch to Off. c) Use Airplane mode in low/no coverage areas if you cannot use or don't plan to use data over your mobile network.

Settings > Wireless & networks > More… > select Airplane mode. Although mobile network connection is disabled in airplane mode, Wi-Fi can be re-enabled: Settings > Wireless & networks > Slide the Wi-Fi switch to On. d) Enable auto brightness.

Settings > Display > Brightness > select Auto e) Reduce the delay before the screen goes to sleep. The screen is often the biggest drain on the battery, and this step will reduce drain when the screen is not in use.

Settings > Display > Sleep > Set small time frame (such as 1 min or less) f) Minimize use of graphic or memory intensive apps when you need to conserve battery. This could include video streaming, gaming, or camera use.

g) If you know you are going to use intensive features more than usual, such as when traveling, plan in advance.

Plug in your charge cable while using GPS navigation in your car, if able. Carry around your USB cable and plug into USB ports to charge, if able. Bring a backup battery for your device when taking many photos and videos, if possible. h) Disable application notifications from apps that are giving you unwanted or too many notifications.

Settings > Apps > touch the specific app > uncheck Show notifications Touch the Back button (curved arrow toward the bottom left of the screen) and repeat as necessary for other apps. i) If you're using a tablet and have multiple user profiles, switch to unused profiles and (similar to step a) use the Recent Apps button to close all the apps open on that profile.

Alternatively, you can delete unused tablet user profiles: Settings > Users > touch the trash can to the right of the profile you wish to delete. The main user profile can't be deleted. If your battery still drains unusually fast after going through all the above basic steps, try Steps 5-7 below.

Step 5: Use the Battery settings.

Visit our Manage battery life help article. Check battery level & usage details of your device to determine if any unused features or third-party installed apps are draining the battery quickly. Step 6: Enable safe mode on your device.

In safe mode, all third-party applications will be disabled. This can help pinpoint issues caused by third-party installed apps. To restart your device in safe mode:

Ensure your device's screen is on, then press & hold the Power button. Touch & hold the Power off option in the dialog box. Touch OK in the following dialog to start safe mode. To exit safe mode, turn your device off and on again. It's recommended that you try safe mode for a few hours or up to a full day, if able. If your battery continues to drain abnormally quickly while in safe mode, try Step 7 below.

Step 7: Reset your device to factory settings.

If your device continues to drain quickly, resetting the device to factory settings may resolve the issue. Resetting your device to factory settings will erase all local data on your device. Backup of your personal local data (pictures, music and video files) is recommended.

To backup personal data on your device To reset your device to factory settings After resetting your device to factory settings, continue to use your device normally to determine if your battery issue is resolved.
