Samsung

App killing was significantly increased on Samsung's Android Pie flavor. Adaptive battery is much more eager than in stock Android.
After 3 days any unused app will not be able to start from background (e.g. alarms will not work anymore). For the proper work user should turn off Adaptive battery and Put apps to sleep options using instructions below.

Important: Even when these options get disabled, Samsung may re-enable them later after a firmware update!

Samsung Android 9 (Pie) and newer devices

For Samsung Pie devices you should verify 2 main settings:

  • Allow background activitiy and Optimize battery usage
  • Allow background activity

Allow application work in the background:

  1. Go to SettingsApps
  2. Find your application and tap on it
  3. Tap on Battery
  4. Switch on Allow background activity

Steps on Samsung Galaxy S20:

Optimize battery usage
To exclude application from battery optimization:

  1. Navigate to your app’s battery screen (1-3 steps from Allow background activity)
  2. Tap on Optimize battery usage if it says Optimize battery
  3. Find your application in the list and switch off toggle
  4. Navigate back to app’s battery screen and check that Optimize battery usage says Not optimized

Steps on Samsung Galaxy S20:

Samsung Pre-Pie Android versions

With the introduction of Galaxy S8 (and with some earlier experiments), Samsung has introduced a flawed attempt at prolonging battery life called App power monitor.

For your apps to work correctly, please whitelist them in App power monitor.

How to do that:
Open the Settings > Device maintenance > Battery and at the bottom you’ll see a list of your most frequently used apps. You can manage apps individually or in a group by selecting them and tapping the big Save power button. Apps that are sleeping will appear in the Sleeping apps list at the bottom (tap it to expand the list). Scrolling further — all the way to the very bottom — and you’ll find Unmonitored apps. These are apps that you specifically want to exclude (whitelist) from App power monitor evil reach.

In the Unmonitored apps menu, you can tap the 3-dot menu to add or delete apps from the list. Rather than bothering with any of that, you can just turn off the App power monitor feature completely as it has little-to-no impact on battery life and only serves to handicap the normal functioning of your Galaxy device.

It’s excessive and in some cases downright misleading, using scare tactics to keep you reliant on Samsung’s software when other Android devices get by just fine without it.

On some phones with EMUI 9+ (Android P+) Huawei introduced a new task killer app called PowerGenie which kills everything not whitelisted by Huawei and does not give users any configuration options.
We've got mixed reviews on Huawei - the PowerGenie app is present on some EMUI 9+ systems, while on others it isn't.

Traditionally, Huawei and their Android customization called EMUI belongs to the most troubled on the market with respect to non-standard background process limitations. On default settings, background processing simply does not work right and apps working in background will break.

In some of the EMUI versions (we know about EMUI 4 and we've got some reports about EMUI 5 and now the latest EMUI 9) no user accessible settings can prevent the system to break background processing longer than 60 minutes. This is done by a custom service called HwPFWService (and in EMUI 9 this is called PowerGenie) developed and bundled with EMUI by Huawei.

App Launch on some EMUI 8, 9 and 10 devices (Huawei P20, Huawei P20 Lite, Huawei Mate 10, Huawei Honor 9 Lite, Huawei Mate 9 Pro etc.)

  1. Go to your phone's Settings.
  2. Tap on Battery.
  3. Tap on Launch (Honor 9 Lite, Mate 9 Pro) or App Launch (P20, P20 Lite, Mate 10).
  4. Set your app to Manage manually.
  5. Turn on every option for your app.

Startup manager
Startup manager seems to be a new kid on the block, preventing apps run automatically after the phone starts up.

Xiaomi

Traditionally, Xiaomi and their Android customization called MIUI belongs to the most troubled group on the market with respect to non-standard background process limitations and non-standard permissions. In default settings, background processing simply does not work right and apps using them will break.

Autostart

The main restrictive setting is called Autostart. It may vary on different Xiaomi smartphones.

Option #1

Option #2

App permissions and a Battery Saver setting

  1. From your app's battery screen, tap on App permissions.
  2. Turn on Show on Lock screen, Start in background, and Display pop-up window.
  3. Go back to your app's battery screen and verify that Other permissions say Allowed for 3 permissions. Scroll down and tap on Battery saver.
  4. Choose the No restrictions option.
  5. Go back to your app's battery screen and verify that all 3 sections has successfully changed. Battery saver should now show No restrictions.

App pinning

When you open the recent apps tray, drag your app downwards (it will be locked). So, even if you clear recent apps, it will not clear them from the background. Drag downwards again to clear your app from the background.

OnePlus

OnePlus with OxygenOS Android modification is known for maximizing the stock Android experience. This may be true on the UX front but the exact opposite is valid for background process limits.

When releasing their 1+5 and 1+6 phones, OnePlus introduced one of the most severe background limits on the market to date, dwarfing even those performed by Xiaomi or Huawei. Not only did users need to enable extra settings to make their apps work properly, but those settings even got reset with firmware updates. So apps break again and users are required to re-enable those settings on a regular basis.

Deep optimization

The OnePlus restrictive setting is named Deep Optimization. Here are the steps to turn it off:

  1. Go to your Settings → Battery.
  2. Tap on Battery Optimization.
  3. Tap on the ⋮ 3 dots menu icon and tap on Advanced Optimization.
  4. Toggle Deep Optimization to OFF.

Battery optimization

Recent apps clearing behaviour

Normally when you swipe an app away, it won’t close. Android handles that well on its own. On OnePlus this may however work in a different way. Recent app clear behaviour manager might be set up in a way that swiping the app to close will kill it:

Lock your app in Recent

Meizu

  1. Device Settings → Advanced Settings → Battery manager → Power plan set to Performance
  2. Device Settings → Advanced Settings → Battery Manager → Protected apps – check your app as Protected
  3. Enable Device Settings → Apps → your app → Battery → Power-intensive prompt and Keep running after screen off

Asus

Asus phones have their own optimization tool called Power Master. To make sure apps background processing works, set up the following:

  1. Go to Mobile Manager → PowerMaster → Settings (or Battery-saving options)
  2. Uncheck Clean up in suspend
  3. Uncheck Auto-deny apps from auto starting.

Vivo

Autostart

This option should be present on all Vivo phones. To turn it off:

  1. Go to Settings → More settings
  2. Tap on Applications
  3. Find your application and turn on Autostart toggle

For Funtouch OS 2.6 and lower version:

  1. Go to iManager → App manager
  2. Tap on Autostart manager
  3. Turn on the app switch

Vivo Y91
1. Lock the app in taskbar
Apps locked in the taskbar are safe from getting terminated when they run on the background.

  1. Swipe up in your home screen while the app is open in background, and swipe the app icon down.
  2. Tap the lock icon.
  3. Done - now the app is locked in the taskbar.

2. Allow the app to keep running even during high power consumption

  1. Go to system Settings → Battery.
  2. Go to High background power consumption.
  3. Find your app in the list and enable the high battery consumption.

Wiko

Wiko devices are however definitely problematic in terms of non-standard background process optimizations and adjustments to the settings that need to be done to make apps work properly.

Turn off Eco.Mode and disable Optimized mode

  1. Go to Phone assist
  2. Tap on Power Saver
  3. Turn off Eco. Mode
  4. Tap on Optimized mode
  5. Disable Optimized mode and make sure your app is not optimized

Add app to background whitelist

  1. Go to Advanced settings
  2. Tap on White-list apps background
  3. Find your app in the list and enable it

Alternatively

Go to dialer and put the code ##86569726## and uncheck Lowram Enable and Background enable.
Note: This needs to be done again after reboot.
