@matt1998Ever tried to backup & reset to Factory Default + Wipe dalvik cache over recovery? Worth to try.
If nothing happen, then we know its the battery issue already.
@Vcys86I was on various rom before and I can summarized:
Pure Rom by DigiGoon: Very light + fast + smooth etc + no longer supported + security patch outdated
Lineage OS by Papsi: Battery hunger + no issue with whatsapp & other notification + on going bugs (even with xPosed) + support is about 50-50 from dev.
Lineage OS Reloaded by WBT: Battery consumtion depends on your usage. tricky part on the doze usage of Naptime and Amplify - trust me, you don't want to mess up on this
MiUi for Honor 7 by WBT: Almost perfect rom for daily usage. Base from China rom + have build in CM call record. Problem with Magisk (root alternative). Magisk hide won't work well with banking apps such Maybank + Cimb. If you are okay with no root, this Rom is a new experience.
Stock China (PLK-TL00C01B388): Rom is stock, just need to install Google play from HiApp during the 1st setup. Have a lot of features such as build in call recorder + Dual App + Split screen. Works with Magisk root & normal root. The only problem I had was - this rom does not keep the apps that we protected.

(you know what i mean) when we clear everything, it will clear everything and will not keep the selected protected running service. Unless, need to move the whole directory from \data\data\ to \system\priv-apps
Stock Malaysia (PLK-L01-C636B375): Finally, im back to M'sia stock rom

. Can't say how much i missed the good old days. Best rom ever! I mean, with the latest security patches dated Nov 6 2017 + Magisk hide (root) works perfectly on banking apps. Protected apps working fine + battery consumption is good + i can manually add split screen, etc...
so.. yeah, i go for Malaysian stock rom

Hi fiezwan..
Okay..I just downloaded Malaysia stock rom - update.zip.
May I know if I can follow this guide to flash from PURE rom? How can I do a full wipe before installing? Or is it part of the installation process?
