Mate 8 NXT-AL10 B592 Clean Stock & Custom ROM TWRP Backups / Battery Life Comparison

Hey guys!

So i finished uploading the clean install TWRP backups of B592 Stock and the three currently available custom roms for our beloved Mate 8 phones!

TWRP Backup Details:

- Clean installation of B592 Stock ROM

- No Apps removed, only settings changed are: Display set to 10 min / Developer Options enabled / USB Debugging enabled

- Custom ROM clean install: Clean B592 Stock as base install, followed by TWRP flash of respective custom ROM on top

- TWRP backups cover ALL available partitions

HowTo Installation:

- Make sure you are on the latest Nougat Stock ROM of your respective Model and Cust

- Install the latest TWRP 3.1.1 via fastboot or your currently installed TWRP (download available further down)

- Important: BACKUP! BACKUP! BACKUP! Make a full backup of ALL partitions of your current ROM, just in case something goes wrong

- Check the location youve saved the ROM backup to: You will see that inside the TWRP/Backups folder there is now a folder with a custom name connected to your phone. Inside THAT folder the actual backup folder resides. Example in my case: Ive saved my TWRP backups to the external SD --> /TWRP/Backups/CJL5T15C180xxx/NXT-AL10 B592 Stock/

Thus, the actual backup files for the partitions reside in the Backup folder "NXT-AL10 B592 Stock", which I have named during the Backup Process in TWRP

- Download the TWRP Clean Install Backup of your choice from the Download link provided below

- Unpack the downloaded zip (THIS IS NOT A FLASHABLE ZIP! IT WILL NOT WORK BY JUST FLASHING IN TWRP!)

- Copy the unpacked folder into /TWRP/Backups/(Folder with custom name specific to your phone)/ as mentioned above

- Do a manual wipe of ALL partitions EXCEPT internal storage and sd card (this is NOT the standard complete wipe, you have to MANUALLY select all partitions yourself!)

- After the wipe, DO NOT REBOOT

- Go back to Main menu, go to restore and select the backup you have previously copied into the TWRP/Backups/"Custom name" folder

- Reboot and profit :)

Note: Since I have made all of the TWRP Backups with a NXT-AL10 phone and cust I cannot guarantee that all backups will work on all phone models and cust regions! So try for yourself and please report back :)

Edit: Reported to work on L09 phones! I still need confirmation for L29 guys :)

Battery Life Comparison

Since I now have easy access to Stock and custom clean installs of B592 I wanted to include a battery life comparison. So I did the following:

- PCMark Work 2.0 Test as base for battery life testing

- Measurement of time it takes for battery to go from 100% to 20%

- Settings: Wifi+BT+GPS off, Mobile Data on 3G, Display screen on full brightness, CPU/GPU Stock

- Aside from PCMark, no other Apps have been installed or removed from respective Clean Install State of each ROM

NOTE: I set display to maximum brightness to have a specific point to compare to on all roms (due to lack of a brightness meter). Plus, it doesnt take so long for the test to finish compared to minimum brightness ;)

Be aware that all Benchmark comparisons found online are based on a display brightness of 200 nits, so you CANNOT compare these results with others!

For fun and comparison´s sake, I also included my current ROM, which is based on the DL00 B592 Stock TWRP Backup provided elsewhere in the Mate 8 section, with B592 Kangvip v2 flashed on top. Be aware that this is my daily driver, so a lot of tweaks, app changes, setting changes, etc have been applied! Short Rundown: CPU on Powersaver Governor, Mobile Data on 3G, Wifi+BT off, GPS on battery saving, tweaked App permissions and battery options, etc.

Results so far:
