Battery Calibration is a Myth

---

All over the forum, people are going nuts about battery stats, calibration "techniques", apps, scripts etc... to "improve" your battery life. What the hell is up with all this battery calibration mumbo-jumbo?

I don't know who started this, but this calibration, battery stats wipe thing is just plain annoying now. It is a useless, superstitious, ritualistic and nonsensical practice... just as useless as the Task Killer apps and scripts floating around.

I know y'all will boo me for flipping a finger at this sacred ritual that everyone on android seems to be following, so allow me to let Google Engineer Diane Hackborn convince you... (unless of course you believe that you understand how Android works even better than the guys that designed it...)

OPEN YOUR EYES (and mind) and READ THIS

Please understand that i am only posting this because all this battery stats wiping and calibration etc is just a pagan ritual and doesn't really help. We're just being herded along like sheep, just as was the case with task managers (still is) aome time ago. Break this vicious cycle...

Enough ranting. It's your phone, do what you want with it. It's not like I'm Steve Jobs (may God have mercy on his soul) or Bill Gates to dictate how you use your phone...

Myth debunked! I suspected as much. I usually forget the battery stats thing and never noticed any different battery life. Just some odd representation of dialer usage in battery stats. Thanks for the find.

Read this already. And never whiped the stats before :)

That's good to hear. Never calibrated because I'm too lazy. The whole thought of charging to 100% then letting it discharge and then charging it backup to 100% was just boring! Plus I hate letting my phone die. Thanks for the info enigmaamit!

You have great style, man. Love the relevance of your posts, and well constructed structure. This post made me think again about things we have all blindly accepted as the norm, without even questioning the logic behind them. Thank you for the insight. Battery calibration was the most irritating thing for me, and i will never do this again! I have opened my eyes...

Thanks for this. Its interesting to read, and good to be able to tell my mates "I told you so" as I have never bothered calibrating my battery stats. Getting over 48hrs of normal use (calls, data, wi-fi, texts, browsing etc) on a MIUI build is good enough that I never felt the need to even consider caibrating.

Thanks for the heads up

u should link to this in the battery calibration thread! Afraid I don't know how to cross link whilst posting on my phone.

It's not completely useless. You can for example delete the batterystats.bin file at any battery level and keep your phone in standby to see what is causing a battery drain in the battery usage UI.

That post by Diane didn't really mention anything about calibration though, just the batterystats file. However I have always been pretty sure that charge/discharge calibration is a myth ever since Li-Ion batteries became mainstream. That type of calibration only really helped with the old school Ni-Cd batteries. I ain't calibrated a battery in my life and I am still alive and happy.

Mother of God!

How dare you, imposter! challenge our ways of maintaining our handset's life and mind's sanity, how dare you question the teachings of mAhro jr., you dare come to our land, and question our ways that has been passed along from an android's incrementation to another?

Feed The Imposter to the lions!

jk xD
Again, kicking ass with your posts, i always knew that this calibration thing is a gimmick, the effect could be a huge placebo and i think whoever designed android/batteries knows better than to leave the records tied to software, no? anyways great post

But that what would the calibration cult say o3o
