Simplest way to calibrate your Battery [for root users only]

[shranav]

I noticed that in CWM 3 (on gingerbread running device), when u click on wipe battery stats in CWM, Nothing happens while in old CWM's when we use to click on wipe battery stats, we get a message "battery stats wiped successfully".
So to wipe my battery stats, i found a software in android market called "battery calibration"
Just download this software from market (its free) and you will get your results.

I plugged in the cable to get to 100% charge (4250mV), I clicked "Battery Calibration" then waited until it was done and unplugged the phone. Then it was at 99% wtf. What does this mean? Is my battery calibrated now or what?

Multiple posts on here full battery reads 100-97%


Battery is only calibrated after battery stats wiped battery drained and charged to 100% then phone used for two weeks .

Thanks for the info, man. So, now that I have calibrated with this app, I just have to drain the battery to 0% - then the phone turns off automatically - and recharge till 100%, then it's calibrated? Woah

PS: Do i have to recharge my phone while it is on or better while it is off?

Galaxy S 2.2.1 firmwares never show 100% battery life when not on charger. As soon as u unplug ur charger the level will drop to 96% or something. Reconnect ur phone to charger again and after 5 mins it ll again show 100% than again as soon as u unplug it, the level drop down to anywhere more than 96%.

just untick wait for 100% option in battery calibration software and ur battery ll be calibrated. do once ur phone is fully charged and once when ur battery level is just 1-2%

Actually its down to the modem version you run.

I ran one modem version that gave me excellent battery life (near on two days of constant use and only 50% drain. Also it STAYED at 100% for about 20 minutes after unplugging if i didnt use the phone, when i used this modem.

The problem is that to get better battery life you have to compromise on signal quality on the modem. The less battery the modem uses usually results in less signal strength, because its not using as much power to find its mast.

read #11 in "Getting the most out of your SGS" thread. That section is on why it's not good to overcharge your battery.

11. Do NOT overcharge

--Why, when, where: Almost all new batteries have an overcharging protection. This means that the protection that is built into the battery will not let it charge to 100%. This is a feature, not a bug! This will help prolong your battery life while also keeping it safe from overheating/explosion/etc. Do not try to trick it and unplug and plug again until you see 100%, just get used to the fact that you can't have 100% battery anymore and live with it, or you risk destroying your battery.
