Battery Warner Pro v1.147 [Latest]

Battery Warner Pro

What is this?That’s a battery warner, that warns you, when your battery reaches X% on charging or Y% on discharging.

Why should i need that??

Lithium-ion batteries have a longer life, if you pay attention to the following things:
– Don’t let the battery too long at 100% on the charger
– Don’t discharge it completely
– For the longest life, you need to load “flat”
–> That means, that you charge e.g. between 20-80% instead of 0-100%

And to help you with that, i developed that app:
– It warns you when charging and reaching X% to help you to load “flat”
– And when you discharged to Y%

Another point is, that you save time, because batteries load slower at 80+%!

Other Features you can use without root:
– Creation of a charging graph, so that you see how you have charged and how warm
the battery got.
– History of past chargings and auto saving of the charging graphs
– An battery information notification with the current state of the battery
– A dark theme -> optionally also for the info notification!
– You are able to toggle the battery warnings for each charging method (ac charging,
usb charging, wireless charging) separately.

Other features where you need root for:
– Stop charging automatically, so you don’t need to be in the near of your device to hear
the battery warning.
-> That does not work with every device! I have to optimize the app for some devices!
– Smart Charging – controls the charging for longer charging sessions (for example over
night) to make the battery have a longer life.
-> For that “stop charging” needs to work on your device!
– Disable USB charging
-> This prevents charging when plugged in via USB.
-> This also needs “stop charging” to work for your device!
– Resetting the android internal battery stats when the battery high warning triggers.
– Enabling the power saving mode when the battery low warning triggers.
