Increasing Androids battery life (daily and total)

It all about reducing battery stress and use

To reduce use:
I installed "Disable Application [ROOT]"
https://play.google.com/store/apps/details?id=com.iamaner.oneclickfreeze
and then I created shortcuts to disable the popular battery eaters "Google Play Services" "Chrome" and "Google Maps". I enable Services when required by other apps, but off when not. Now my battery consumption stays nearly flat when the phone / tablet is not actively used.

You not only will note that the battery last much longer, but it also charges quicker.

I also disabled apps that I use rarely but like to be doing things even if you don't open them.

There are many other things you can do to reduce battery use, but this is one that I never explored.

To reduce stress:
1. Try to eliminate frequent small charges (when cable is connected for long time and battery is full). For that I use "battery full notification" [1]

When charge is about 98%, I hear notification every minute to unplug the cable.

2. Sometimes I get a faulty cable / charger. If I suspect that, I activate "battery log"

to know if there are frequent disconnections to the cable [2]

Thanks to the creator of those free apps.

[1] Ideally, I would like an App that disables charging until the battery reaches a threshold like 90%, so you would NOT need to unplug the cable when the battery is full (my laptop does that).

[2] One morning I noticed the phone was charged during the night intermittently due to a bad connection of the cable. Reeealy bad for the battery.
