Root [REF] THE Battery Calibration Method

[LDrifta]

ok, this is not MY work or research but it's something I tested in my own way and it works 100%!!! SERIOUS THANKS to zeppelinrocks from xda, here is the link to original post, but i will provide MY personal method (which is basically the same) lol

http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10

ok so here's what I did...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1: Charge device fully to 100%

2: leaving the charger plugged in, press and hold power untill power menu pops up

3: now select 'restart' and wait for device to power itself off

4: as soon as the device turns itself back on and you see the 'LG' logo apear, pull OUT your battery!!!

5: after the device shuts itself off put the Battery back in (still leaving the charger connected the whooooole time)

6: now after the 'power-off charging' screen shows up, press and hold power button untill screen goes blank, then just wait 5-10 seconds untill device powers itself back on, now your battery should be at something lower than 100, like 80-ish lol

7: charge fully and repeate if neccesary!!!

again huge thanks to zeppelinrocks for this method, i got like 5 hours back on my device thanks to him!!!

Hey L u forgot to put in deleting battery stats in data/system/battery stats before restarting just a heads up tried it with out deleting battery stats it stayed at 100%

i didn't have to, i think he said it re-creates one at boot or something so you have to pull your battery out within 3 seconds of that lg logo.. "i think" lol

 

[jahunt78]

I didn't get results until I deleted mine deleted it and mine dropped to 71% I tried a couple times without deleting it

hmm maybe ill give it another try lol how you delete them? maybe that app i downloaded did it for me? lol

 

[h4x0rj3ff]

I believe you do it in advanced in cwm

Edit: I've always used battery celebration app in the play store. Its like a white icon with a green battery on it

 

[jahunt78]

Rom tool box root explorer how I did it or root explorer and navigate to data/system/battery stats file

 

[h4x0rj3ff]

Just tried it and I didn't have to wipe batt stats and when I rebooted it was at 92%. Gonna wait till it charges back to 100% and do it again. Should we do this often or until we turn our device back on and still have 100%? What do you suggest o great LD?

lol nah jus maybe once every few months to make sure.. but i wouldn't do it too much since im not 100% sure if it's a good or bad method of calibrating the battery lol oooOOOooOOOooo

I thought this whole battery calibration stuff had been debunked by Google devs?

im not sure what you mean by that lol but this seemed to work for me...

 

[jahunt78]

There are some issues doing this this is the second time this has happened but I go to do this process a second time just to make sure and it hangs at 98% for about a half hour but as I am typing this out finally hit 100%

Noticed something.. Without unplugging the battery just a regular restart drops the percent even plugged in.. Know a reboot has always drained an esteem.. Not trying to debunk this is or anything along those lines but it also will charge without the reboot back into the system and not cause the boot drain.. It reminded me of a trick i learned back in the ascend days.. Was called boost charging, jump charging, something along those lines.. Charge phone till full with phone off, remove battery, replace, let it charge again with phone off, repeat..

yeah that sounds about right.. but i mean the battery dont jump to 80 from 100 on a regular reboot with charger plugged in.. i would know because i reboot my phone all the time lol (testing purposes) but he also states in the xda post that the device re-creates the battery stats on boot, so im sure yanking the battery out before hand does help in some way to get a better reading of your battery

Yeah.. Tried a few different ways and only get results by pulling the battery on reboot.. Got one more thing to try after juiced again.. Delete batt stats and pull while running.. Edit.. Nothing..

Anyone else wanna try the last way mentioned? Think my batteries are super juiced at the moment from testing

 

[jahunt78]

Only way I get results is deleting battery stats without deleting it always stayed at a hundred for me

 

[h4x0rj3ff]

Whether it is a placebo or not is irrelevant to me. I switched to LD-LG yesterday before I did this so that could be it but I lasted all day today and I still have 59% left over 15 hours (with little use) by this time normally my phone would be ether red with 10 or less % or off. Thanks again L.

or simply fully charge and reboot. Google itself has already debunked wiping battery stats etc.

though what you say may be true... i have fully charged and rebooted my device many times in the past in 'other' failed attempts of 'calibrating' the battery, and never have had results like this.. so maybe i miss-understood and your saying you agree with this method and NOT wiping batt stats lol, but if you think the idea of calibrating the battery is a hoax than think again my friend lol this definitely, without a doubt worked!! and i definitely have a good extra 5 hours of life doing the same ol song and dance every day with this baby lol

so again sorry if im mis-understanding the posts.. but i do have to defend myself from time to time even from the wrath of gods haha

well google debunked wiping battery stats, never mentioned calibration, so my comment may not apply.
