So maybe you are looking for a tweak to gives you a certain and useful information about your iPhone battery and how it will last long. Of course there is BatteryDoctorPro, Battery statue and now we are going to add a new jailbreak tweak to the list called iBatteryInfo.
This simple utility offers up all kinds of useful data, like whether
or not your battery is fully charged, when plugging in and unplugging
your iOS device…
There’s really not much to the tweak itself. It doesn’t have a Home
screen icon, and there’s only a single option to configure in the
Settings app: a toggle for enabling or disabling the tweak. But the data
it offers is much more complex.
As you can see in the image above, iBatteryInfo gives you a wealth of
information including how charged your device is (measured in mAh),
what its battery’s max capacity is (also in mAh), and whether or not
it’s really fully charged.
That last spec is nice because sometimes your device will say it’s
fully charged, but it’s really not. Total charging cycles, your
battery’s serial number and a few cable details like Watts and amperage
output round out the available data.
This tweak will be very useful for you, and I have already tested it on my device and it is working great.
You can download it from Cydia store for free via BigBoss repo.
