[Verizon Droid Charge] criticalhit:
Hello Everyone,

I have been asked to put together an instruction on how to correctly calibrate

your Sammy Charge battery... so here it goes.

First of all you need to be ROOTED there are plenty of roms and kernels here

for you to pick from so get the package you want Odin or Clockwork whatever you want.

-i will be referring to Clockwork Recovery Mod as 'cwr' from now on-

I am currently running IMNUTS 710 Non-Overclock Kernel and Humble 1.4.2 ROM. Humble ROM comes with a battery calibration app that you might find helpful for this task.

The kernel or rom you have doesnt matter for calibration but you must have the latest cwr witch is bundled with any of IMNUTS' Kernels.

You may have heard of the term 'Bump Charging' this only needs to be done before you calibrate (so you Chargers that are doing this every full charge, you are wasting your time). I will explain what this is if you do not know.

Here are the steps:

1.Turn your phone ON and charge it to 100%

2Turn your phone OFF and leave it plugged in. (you will notice that the battery will begin to

charge again but it will not be at 100% anymore it will show something like 95%.

3.LEt your phone get back to 100% (it will vibrate when it is done)

4.Unplug your phone, wait 30 seconds, and plug it back in.

5.WTH! it is back to 95% again!dont panic... LEt it charge again to 100% (2-5 minutes)

6.Now do it again. (unplug wait 30 seconds, plug in, let charge to 100%)

continue this until it shows 100% after 10-20 seconds on plug in. (it took me 15 times,

although i have seen upwards of 20 times)

- some users are saying that the time does not decrease to 100% while doing step 6, 20 times is good enough as all phones/batteries are not from the same mold-

7.Now boot into cwr (if you dont know how then you shouldnt be here)

8.Go to the advanced menu and 'wipe battery stats'

9.Reboot phone via cwr

(((this is where it will differ from the other posts or whatever)))'

10.Drain your phone to 0% and immediately plug it in. (others will tell you to let it die completely and shut itself off... YOUR PHONE WILL NOT LOG CHARGING INFORMATION IF IT IS OFF!!! ((I suggest you do a little troubleshooting to see when your phone will actually turn off. Mine turns off after being at 0% for a few mins. Your's may shut off at anywhere between 10%-0%. If it does shut off just turn it on again and plug it in)). Basically what u am saying is make sure your phone is ON during charging while doing these steps.

11.Charge to 100% (DO NOT UNPLUG IT WHILE IT IS CHARGING... if you get a call or a txt it is fine to use it a bit (and for clearification on 'proper charging' I contacted Samsung it is OKAY to use phone while charging (my bad)).

12.I did this full charge and full drain, plug in at 0% -ON charging, 4 times.

13.Charge it whenever you want.

The android OS logs 'battery stats' and charging habits based on a small window of use. Following these directions will let your phone lock in enough information to max out your battery life.

With strong 4G signal expect 18-20 hours of light use. If you are in a known 4G deadzone download LTE Switch from the Market, it lets you turn off the 4G radio and run only 3G. I personally turn off mobile data unless i need it and have no syncing actions automated. My best uptime was 41 hours and 12 minutes to 0%. Dont forget that all roms and kernels are different so your results will vary. If you are on your phone all the time... playing games, on the net, making calls you will of course have less time.. with heavy use i can burn 10%-15% an hour easy. Get rid of your 'antivirus' crap, your monitoring apps all that shat... it will only sacrifice your battery and it is unnecessary.

For those wondering about LAGFIX:

AlexDeGruven states-

'RFS is the bastard child of FAT and a Samsung developer who didn't understand how modern filesystems work with NAND storage. It has nothing to do with battery usage. For data access, the longer it takes to access the data, the longer the processor is waiting and running wasted cycles. The faster the data is returned from storage, the less battery gets used.'

So turn it on or leave it off, up to you.

I hope this helps everyone get calibrated.

Let me know if you have any questions.
