Tips for extending battery life

How long the battery can last before it needs recharging depends on how you use

HTC Desire 550. Try out some of these tips to help increase battery life.

Use the power management features

§ Turn Power saver mode and Extreme power saver mode on in Settings.

Monitoring your battery usage helps identify what's using the most power so you can choose what to do about it. For details, see

Checking battery usage on page 122.

Manage your connections

§ Turn off wireless connections such as mobile data, Wi-Fi, or Bluetooth when not in use.

§ Turn GPS on only when a precise location is needed, such as while using

navigation or location-based apps. See Turning location services on or off on page 219.

Turn on Airplane mode when you don't need any wireless connections and you don't want to receive calls or messages.

Manage your display

Lowering the brightness, letting the display sleep when not in use, and keeping it simple helps save battery power.

Use automatic brightness which is the default, or manually lower the

brightness. See Screen brightness on page 224.

Power and storage management 119

Set the screen timeout to a shorter time. See

Setting when to turn off the screen on page 224.

Don't use a live wallpaper for your Home screen. Animation effects are nice to show off to other people but they drain your battery.

Changing your wallpaper to a plain, black background can also help a little.

The less color is displayed, the less battery is used. See Setting your Home wallpaper on page 76.

Manage your apps

Battery optimization helps extend battery standby time. See

Battery optimization for apps on page 123.

Install the latest software and application updates. Updates sometimes include battery performance improvements.

Uninstall or disable apps that you never use.

Many apps run processes or sync data in the background even when you're not using them. If there are apps that you don't need anymore, uninstall them.

If an app came preloaded and can't be uninstalled, disabling the app can still

prevent it from continuously running or syncing data. See Disabling an app on page 87.

Limit background data and sync

Background data and sync can use a lot of battery power if you have many apps syncing data in the background. It’s recommended not to let apps sync data too often.

Determine which apps can be set with longer sync times, or sync manually.

120 Power and storage management

In Settings, tap Accounts & sync and check what types of data are being synced in your online accounts. When the battery is starting to run low, temporarily disable syncing some data.

If you have many email accounts, consider prolonging the sync time of some accounts.

In the Mail app, select an account, tap Settings Sync, Send & Receive , and then adjust the settings under Sync schedule.

When you’re not traveling from one place to another, sync weather updates of only your current location, rather than in all of your named cities. Open the

Weather app, and then tap to edit and remove unneeded cities.

§ Choose widgets wisely.

Some widgets constantly sync data. Consider removing the ones that are not important from your Home screen.

In Play Store, tap Settings , and then clear Add icon to Home screen to avoid automatically adding Home screen app shortcuts whenever you've installed new apps. Also tap Auto-update apps Do not auto-update apps if you're fine with updating apps from Play Store manually.

Other tips

To squeeze in a little bit more battery power, try these tips:

Tone down the ringtone and media volume.

Minimize the use of vibration or sound feedback. In Settings, tap Sound & notification and choose which ones you don't need and can disable.

Check your apps’ settings as you may find more options to optimize the battery.

Types of storage

Starting from Android 6.0, there have been some changes on how and where downloaded apps and their data can be stored.

Phone storage

This is the internal storage which contains the Android system, preinstalled apps, email, text messages, and cached data from the apps. You can also install apps that you've downloaded and capture photos, videos, and screenshots to this storage.

Storage card

Use your storage card as a removable storage to store and access your media and other files on HTC Desire 550 or any Android phone, or set it up as an extension of the internal storage. See

Should I use the storage card as removable or internal storage?

on page 125.

Power and storage management

Should I use the storage card as removable or internal storage?

125

Use your storage card as removable storage when there's already content such as your media and other files so that you don't lose these content. If you have a brand new storage card, choose whether to use it as removable storage or set it up as an extension of the internal storage.

Removable storage

Use a new storage card as removable storage to be able to insert and use the card on

HTC Desire 550 and other Android phones.

Internal storage

Set up a new storage card as internal storage for more privacy and secure use. This encrypts and formats the storage card to work just like the internal storage.

This also expands the internal storage space since:

Captured screenshots, camera shots, media, and other files will be stored on the storage card.

Third-party apps that you installed and their data can be moved between the phone storage and storage card.

After setting up the storage card as internal storage, the card can only be used on HTC Desire 550 where it has been formatted.

126 Power and storage management

Setting up your storage card as internal storage

When you insert a storage card that has not been used on HTC Desire 550 before, the card will be mounted as removable storage by default.

If the storage card is new or doesn't have content you want to keep, you can format the storage card to use it as internal storage for HTC Desire 550.

See

Should I use the storage card as removable or internal storage?

Other backup options

If you want, you can separately back up your data or files.

Some apps allow you to back up data to the storage card—if it's used as removable storage—so you can easily restore them after a factory reset. Just make sure not to erase the storage card when you do a factory reset.

In certain apps, you may be able to use the phone storage for backing up and restoring app data. If an app is causing some problem and you need to clear its data to try resolving the problem, back up the app data to the phone storage first.

136 Sync, backup, and reset

Messages Back up your text messages to the storage card or phone storage, or save them as an email attachment.

Contacts

Save contacts and other personal data to your online accounts so you can just sync them when switching to another phone.

If you have locally stored contacts in the People app, export them to the storage card or phone storage.

Files Connect HTC Desire 550 to your computer as a disk drive to manually copy and paste files to your computer.

Other data Check other apps to see if they support exporting data to the storage card or phone storage.

Using Android Backup Service

Starting from Android 6.0, use the Android Backup Service to back up your HTC phone to Google Drive ™ .

This service can back up and restore the following:

Back up What content or settings are backed up

App data

In HTC apps, app data includes contacts stored on HTC Desire 550, call history, Clock and Weather city list, and email accounts.

§ Data from third-party apps may also be saved in the backup, depending on the app developer settings.

Sync, backup, and reset 137

When auto backup is enabled, the Android Backup Service periodically backs up your phone to a private folder in Google Drive. Auto backup occurs every 24 hours when the phone is idle, charging, and connected to a Wi-Fi network.

Backup data will not count towards your Google Drive storage quota. Large files or files that app developers have chosen to exclude from the service will not be backed up.

Restoring your wallpaper from your old phone may depend on screen resolution compatibility of both your old phone and HTC Desire 550.
