Greets lads,

For "TL/DR"s: Not gaining any battery improvements with root/xposed capable tools (Greenify/Amplify); losing important features like on-time notifications; need help on Greenify settings or alternatives for them.

I am facing an issue, in fact, i always did, when trying to follow battery tips people go for when they root their phones.

I've just recently rooted my Note 8 (Exynos), nevertheless, i always go for a self-controlled system on my phone rather than very modified Custom ROMs, either i modify my stock rom, or find a minimally touched one in the custom rom threads.

Usually, if i achieved massive battery improvements, i ended up with a lot of sacrifices. In previous phones (Note 3, Galaxy A3 2014, HTC M8), i managed to get twice the screen time and battery life when i set-up the usual procedures to , which are: De-bloat (what i dont need and is safe to get rid off), Xposed because of Greenify and Amplify (PowerNap too).

The issues that i would get at these times were delayed notifications i.e from messaging apps, delayed waking up from sleeps (my sleeping, not phone ones) cause the alarm would never make it on time. Now all these apps were white-listed from all the apps that are supposed to limit them.

Now with Samsung Oreo, things look way to weird. My alarm app (Timely) works flawlessly and wakes me up as supposed to, it's untouched by the Samsung Device Maintenance, it is not on the Greenify list, and on Amplify it's not even taken in to consideration as i use the only two features that it allows you in the non-donated version, to limit the wake-ups of Play Services.

However, many messaging apps (obviously white-listed), turned very strange. Many times im in front of my computer, talking on the same platforms already existent on my phone, and 20 minutes later, i open my phone, and i am bombarded by all the incoming communication that i already witnessed on the desktop. This doesnt make any sense.

First, i have already acknowledged them, i was texted on them, i replied, on the desktop. The fact that they show up on my phone means they probably make it in time on my phone, but my phone decides not to wake up. Sometimes it does this without opening the phone up, maybe after 20 to 30 minutes after.

My set-up is: Samsung Galaxy Note 8 (Exynos, SM-N950F), TWRP, rooted with Magisk v16.6, Xposed (Modules: Amplify, Greenify, MinMinGuard), Greenify is Donated version, Amplify is not (would love to, but impossible in my region due to racist google), and root permissive apps such as AdGuard (which is terrible), FX File Explorer (for obvious reasons), Trimmer fstab (not sure if i actually need it), Termux for root shell.

My questions is, WTH am i doing wrong.

BetterBatteryStats shows the usual output on root too, nothing major draining it, but no whatsoever gains of battery life compared to the unrooted past, i mean, 2h screen time with 24h battery life, pathetic, that was the default on my previous 4/5 year old phones, and when i set-up the usual rooted procedures, i would get 4/5h screen time in 48h of battery life.

Any tips on Greenify settings? Any tips for alternative/substitution apps for the ones i already use? (WakeBlock i.e never worked or made my phones unbootable)

Thanks in advance.
