Battery active tweaks settings

Here you'll find one option that requires root and possibly a custom kernel.

Set battery max charge level and the method to apply it.

If there's no method, your device doesn't support charge limit.

This is very useful to prevent battery aging.

How to extends battery life

For information on how to extend your battery life, here is an interesting Wiki (see battery life chapter). 

To extend battery life, the important points are those 2:

• Keep battery cool, and avoid charging past 70% while using the device and creating over-heating.
• You can discharge your battery fully (voltage going down to 3200mV) it won't hurt as 3200mV actual means 40% of battery capacity is left, which is the safe threshold mentioned in the Wiki above!
