How to get decent battery life on Kangvip B588 on B581 - Huawei Mate 8

B581 is actually a pretty good ROM in terms of battery life & Kangvip with all its features installed over B581 makes it a great combo on Huawei Mate 8. There are many people who are getting extremely great battery life on Huawei Mate 8 more than what I managed to get but since you asked me, I am sharing my personal usage & tweaks that I use on my phone.

Chinese Apps

- If you have installed Kangvip B588 over B581 then you can remove all those 10 to 15 apps using "system app remover". These apps are intrusive & have advertisements. That is why I removed them all. :good::good::good::good::good::good:

Settings

- Few tweaks in settings.

WIFI settings - Keep WIFI on during sleep - Never (my setting) & ( you can choose only when plugged in too )

Mobile Data - Here you have 4 different options - Data Usage Setting, Networked Apps, 4G usage ranking, Data saver on/off

Open "Networked Apps" and here you can choose which apps you want to allow in the WIFI or mobile data. :good::good:

If you click on "Networked Apps" on top - you will find two options. Click on "Advanced Network Management" :good::good:

Here you will find all apps and you can choose which apps you want to allow for "Background Data" & "Roaming Data" :good::good::good:

I unticked all except few like Google play store, Google play services & Allo. I allowed only few apps. For ex :- HiGame, HiVoice, Chrome, Google play music, Google play movies - I restricted them completely.

Go to settings - > More - > Link + live update - > Auto update - Never

Settings - > Mobile Network - > choose " 4G/3G/2G/auto " -

And "Mobile Data" - Always on - > Disable this

Display

Brightness - 0 , No auto brightness

Color temperature - Cold

Display - Sleep - > When I use my mobile - I keep it at 10 minutes & when I am going to leave phone idle - I change it to 30 seconds

Notification & Status Bar - Notifications turn on screen - disable

Sound - Vibration, Touch sounds, Lock sounds, Screenshot sound, Power on tone, Vibration when ringing - All are Disabled

Smart Assistance

Enabled - Floating Dock, Double touch to capture (Motion Control) , Touch Disable - glove

Disabled - Everything else - especially Voice Control - HiVoice.

Accounts - Uncheck - Account Sync - this impacts battery life - Check the "auto-sync" and then uncheck everything listed under your google account (ex: Data, contacts, etc... ) :good::good:

Advanced Settings - > Date & Time ( I unchecked "automatic" date/time & time zone & dual clock ) :good::good:

Backup & Reset - > Unchecked automatic backup & restore (Impacts battery life) :good::good:

Location Access (Advanced Settings) - Unchecked the option = access my location :good::good:

Battery -> Lock Screen Clean up - Closed all except - LMT launcher, Swiftly, GSAM battery, kernel auditor, SuperSU etc.

Apps - > Reset app preferences ( useful when you update ROM, resets settings for each app) , I went inside each app and removed vibration, ringtone (vibration - impacts battery) :good::good:

Apps -> Configure Apps - > Special Access - > Ignore Battery Optimization - > If you find any apps here - > Click on them Select - Don't allow :good::good:

Boot up apps

- > Except Accubattery, Gsam Battery, LMT, Swiftly, Lucky patcher, Nova, SuperSu, Kernel Auditor (everything else (user apps) - disabled during start up)

System update - > Uncheck - Auto update via WLAN , even for HiAPP - uncheck - Auto update.

Kernel Auditor

- > Mode - Interactive , Minimum Frequency - 480 & Schedule work queues to save power -> Checked :good:

Greenify

- > I use Greenify for my other tablet but not for Huawei Mate 8 or my Huawei Tablet. Achieved all these results without Greenify. If you use Greenify then go to Apps - > Special Access - > Ignore battery optimization - Choose the option "Allowed" then Greenify alone will handle the app & won't get conflict from Huawei ROM. Huawei is already doing a gr8 job in handling battery optimizations for apps. So it is your choice on what you want & how you want it.

Combination of all these above tweaks helped my phone immensely. Most important ones are the "Backup & Reset" - Auto Sync , Apps - "Ignore battery optimization" under special access - I found many apps here & removed them all. I use Opera as browser, read comments from other people about yandex browser being battery friendly but haven't tried it myself. If you find any "auto update" or "sync" uncheck or disable. Again this is personal choice. The only thing I don't like at the moment is overnight idle drain of 3% in 9 hrs or 4% in 8 hrs. In Gsam - Culprit - phone radio at 85 to 90% usage. Hoping something can be done about this. On my Huawei tablet I have 1% drain in 15 hrs. Otherwise, I get around 10hrs. or 11 hours SOT in 4 days. or 3.5 days. Key is to plug the idle brain drain. :good::good::good::good:

Please note that after all these tweaks it will eventually come down to your personal usage. If you have updated your ROM then your results will vary. Anywhere b/w 8hr to 12.5 hrs means really good battery life. There are people who are happy to get 4 to 5 hrs of SOT only on gaming. So it depends on individual choice of apps & usage. I did fresh install. As you can see my settings, I don't use auto-sync for email (only manual sync) or even 1% brightness. I don't install any app that has below 4.4 or 4.5 rating. I use google play store or xda or aptoide to install apps and NO facebook (huge battery hog & U can use alternative facebook app instead of regular one).

There are other useful battery monitoring apps like betterbatterystats & wakelock detector

You can also have a look at L speed - great app with lot of tweaks. :good::good: :good::good:

Hope you succeed in getting similar or even better battery life. :D :good::good::good::good::good::good: :good::good::good::good::good::good:
