Hello all,
Today we will cover the most discussed but still challenging for many users who are using CyanogenMod 7.1 v1.4. And that is “How to calibrate battery?”
Everyone wants their battery with optimal charging capacity and long lasting especially we are using custom roms.
First of all, Why we need battery calibration?
Well, If you have installed or upgraded CyanogenMod 7.1 V1.4 from V1.3
then it is using new kernel battery driver which requires to remove
old batterystat.bin system file in order to regenerate new
batterystat.bin system file by OS itself which will have updated battery
information to drive it.
Second question may come in your mind, why batterystats.bin file? What’s in that?
batterystats.bin file store battery
storage information and reflect to battery performance. Symptoms of a
bad batterystats.bin include poor battery life, excessive battery drain,
phone is dead within hours or minutes of charging, battery will not
fully charge, etc. These problems occur as the batterystats file may not
know the correct max charge of the battery, or the min charge of the
battery, and thus your battery will be artificially limited between what
the OS thinks is the entire battery when in fact the batterystats.bin
is not telling the whole story.
This operation you can do from CWM recovery manager. Just follow to below steps.
Get into CWM recovery mode. and follow instruction as shown in screenshot?
Another related app we have is “Battery
Calibration”. You can download it from market for free. It basically
does same job as mentioned above but only thing it dosn;t require any
boot. Just look at screenshot it has pretty well defined instructions.
Just follow it and then you good to go with your battery.
Other thing we recommend is do battery
wipe just once when you upgrade or fresh install ROM and perform
charging-discharging cycles 3-4 time.
(Note: Charging -dischargning cycle
require complete draining of battery untill 0% and charge it to 100%
without any break if you want optimal performance of battery )
Hope you get better battery performance. Let us know your feedback, experience , question at below in comment section.
