The Nexus 6P is a brilliant device, but that gorgeous screen is awfully big and crammed full of pixels. While that can be a beautiful thing, it also adds up to one major battery draining machine. So we've compiled a few Nexus 6P battery tips to help you get through a full day of use with battery to spare.
I'm serious, since I unboxed my Nexus 6P I've realized that except in daylight (which there is precious little of at this time of year) the absolute lowest brightness setting on my Nexus 6P is more than enough to see clearly. You don't have to go to this extreme, but keeping your brightness level as low as possible is a wise first move.
2. Make use of Ambient Display
Another great feature of the Nexus 6P AMOLED screen is Ambient Display mode, which you might be familiar with from Motorola devices. The Nexus 6P's Ambient Display mode will intermittently flash your notifications up in gray scale or when you give your Nexus 6P a nudge or pick it up. No need to turn that battery-guzzling color display on to know what's come in since the last time you checked. Go to Settings > Display > Ambient display.
3. Use the included charger and cable
Even though the Nexus 6P doesn't have a “true”USB Type-C cable (it is, rather, a reconfigured USB 2.0 cable like the OnePlus 2 ships with), you'll still get much faster charging using it than any old charging cable and adapter lying around. Of course, you probably don't have a spare USB Type-C cable lying around anyway, but it's always a good idea to use the charger your new phone came with.
4. Choose the dark side
Unfortunately Google decided to ditch the system-wide dark theme in the first version of Android 6.0 Marshmallow, but this doesn't mean you can't do a little bit of DIY theming. For starters, choose a dark wallpaper and if your apps or widgets have dark themes use them too.
5. Turn on Battery Saver mode
Marshmallow has a nice Battery Saver feature built right in, but you'll have to turn it on yourself. Just go to Settings > Battery > overflow menu (three dots in the top right corner) > Battery saver. Battery Saver mode limits CPU performance, cuts location services, haptic feedback and background data, but only when your battery is critically low. You can choose to turn it on automatically at 5 percent or 15 percent battery remaining.
6. Add battery percentage meter
Now, this won't actually help you save battery, but it will help you keep a better eye on the battery life you have by showing an actual percentage rather than a hard-to-define battery symbol. To add a percentage to your battery meter, you'll need to enable System UI Tuner (which is cool in its own right) Just pull down your Quick Settings shade and hold down the cog icon. Now, you can enable this feature by going to Settings > System UI tuner > Show embedded battery percentage.
7. Use Do Not Disturb mode
This feature, also known as Priority Notifications, is an indirect battery saver because it means you'll only be alerted to the notifications you actually want to know about during certain times of the day.
This means no unnecessary battery usage while you check unwanted notifications. It doesn't take long to set up and it will not only save on battery consumption it'll also save you notification headaches throughout the day. Go to Settings > Sounds and notifications > Do not disturb.
8. Give Doze a chance
Doze is perhaps the coolest new feature in Android Marshmallow. When your phone sits idle for a while without moving, it goes into deep hibernation mode. The battery savings with Doze are immense but Doze will be cut short every time you pick your phone up to check for nothing in particular. So give Doze a chance.
If your phone is sitting on your desk at work or school, just leave it there. Ambient Display will still show you any new high-priority notifications (courtesy of Google Cloud Messaging) but Doze will otherwise be optimizing your battery as best it can. All you need to do is fight the urge to pick your phone up all the time.
9. Screen timeout
This is the first commandment of better battery life: keep your screen timeout setting to a short a time as possible. The default setting on the Nexus 6P is two minutes. That means every time you set your phone down without turning the screen off yourself, it will sit there, lit up for no reason, for two whole minutes. Drop that time to 30 seconds – or better yet, 15 seconds – and watch your battery life immediately improve. Go to Settings > Display > Sleep.
10. Keep an eye on apps, widgets and background processes
As always, some apps are killing your battery more than others. Keep an eye on these by going to Settings > Battery and tapping on individual apps (the higher up the list the more battery they are using). Some of these you can't get rid of, like Google Play Services, but others, like the Facebook or Messenger app or Skype, can be force closed or substituted for a different app (web-view Facebook alternative apps are great).
Likewise, widgets are constantly sucking resources to keep updating whether you're looking at them or not, so if you don't really need weather updates 24-7 perhaps you could just try opening the weather app when you need it instead.
You can also keep an eye on background processes in Settings > Apps > select app > Battery to see which apps are constantly working in the background and chewing system resources. Marshmallow conveniently gives you suggestions on what to do (like select battery saving mode for location services or to force stop or uninstall the app).
