[Q] Restore or Wipe - Please Help

HW/SW specifics at bottom (if it helps)
Following the instructions provided this great site I added a custom ROM last year and for 6-8 months everything worked perfectly.
I was getting two days charge out of my battery which was is a 200% improvement. I'm not on my phone all the time.
Lately however, my phone has only been charging to 90%, and now 82% and the batt. drains before the day ends.
Using the same instructions here, I restored the phone using CWM with the files listed below (which are the same files I used originally) to restore my phone.
Everything seems to be working fine but I found a bunch of old files and app links to programs I had before so obviously I didn't do a full wipe which is what I was intending to do.
Can I restore my phone by going into CWM > Wipe data/factory reset or do I have to use ODIN to go back to factory firmware (I just downloaded I727RUXLF3_I727RRWCLF3_RWC.zip) to reset then go through the steps all over again.
Pardon the lack of terminology as I have only done this twice so I'm still new to this.
I just don't know what I need to do to get it back to stock and by stock I mean the ROM below.
Thank you all in advance. Hopefully I have provided enough information.
Samsung Galaxy S II Skyrocket SGH-I727R
ICS RUXLF3radio.zip
SKY ICS 4.2E R5goo.zip
Sky ICS 4.2E-17.zip

If you want to go back to like New condition I would do the odin process. You'll have to extract the .tar.md5 file out of the zip file you downloaded, the stock rom not the sky files. User 7-zip to extract. Put the extracted file in PDA in odin. Only have the auto reboot and f.reset checked in odin.
You'll then have to odin your recovery back on.

Thanks JD I'll give that a shot.

Condition your battery for it to show correctly. Drain battery completely till it won't even turn on. Then plug it in and charge completely with it off. Once done boot phone into recovery cwm. Wipe battery stats. Then reboot.
Make sure battery is not hot to ensure a good charge after draining battery.

First off its actually hard on a battery fully discharge it. Second wiping battery stats does absolutely nothing for the battery or the android system so this tells me you have no clue what you're doing.

Weird battery problem - charging
Ok, here's a weird one, you've probably seen before but it's new to me.
I wiped my phone back to factory stock using Vin's instructions. Followed them to a T and had no problems.
Kies then wanted to update my software (now at 4.1.2) which I let happen because I was just going to wipe it again anyways.
My battery still won't charge past 80%. When turned off, it shows 100% but the second I turn it on it immediately drops to 80%.
The battery life seems to be OK so that's not a problem.
Last night I swapped batteries with my wife's phone (factory stock SGH-T989D).
Here is where it gets weird (for me).
Her phone with my batt. charged to 100% and stays at 100% when turned on.
My phone with her batt. only charges to 80%. Again, when turned off it shows 100%.
So the battery is ruled out as being faulty I would think.
My phone has been factory wiped.... or has it? Did I screw up the wipe and leave some remnant behind?
Is there something I can install that will tell me exactly what is going on?
Suggestions?
I apologize if this type of question has been asked a thousand times but if the battery calibration is a 'myth' then I don't even know what to look for anymore.
Thanks

Try taking the battery out and leaving it out for 5 minutes. While it's out press and hold power for twenty or thirty seconds. That will discharge any residual juice in the phone. Pop the battery back in and power on.

Don't know what else to try

I tried that several different times over the weekend. I got it up to 84% from 80% but now it shows 100% charged within a few seconds after plugging in the phone while it is turned on. When I pull the cable, it goes back down to 84%.
I'm thinking of wiping it again but I'm not sure that is going to resolve the problem. Don't know what else to do/try.

Don't ever do this. Draining your battery below 15-20% is actually bad for it, as the heat generated by simply charging it while idle does damage. It's also been shown that the lower the depth of discharge, the more cycles your battery will have in it.
Also, Android devs who work for the big G have said that battery stats are essentially meaningless in this generation of phones. If you do calibrate your phone, don't run the battery all the way down. Get the 100% baseline, then use it as normal.
Download the battery calibration app. I believe Skyrockets max out at 4330 mV, but I could be thinking of the Note II. If the battery calibration app shows that you're in that neighborhood, who cares if the meter says 100% or not? You're getting a full charge.

Can you recommend a battery calibration app?
I did swap out the batteries as per the post above. I was thinking of charging the wife's batt. to 100% and putting it in my phone. Then do the pull the batt. for five minute trick. At this point it's all about the hail mary.
I'll keep you posted
Update: HAHA! Just gets better and better. Downloaded two battery calibration apps. Both say to charge to 100% before operating... FML.

I use Battery Calibration. It shows the mV along with the charge level. If you're charging to 4100 mV+ when it freezes at 81%, you're doing ok. If you're only charging to 3000-some mV, your battery's borked.

Been testing a few things. I charged my battery to 83% (full) and put it in my wife's phone. It registers as 100% so it's not the battery.
Yeah, I could live with it but it bugs me as I'm sure it would bug you too!
The problem I'm running into is when I put the battery back in it goes to 83%.
I installed two battery calibration tools. Both called 'Battery Calibration' One says it can't operate until the battery is charged to 100% so I'm screwed there.
The other one says my phone needs to be rooted. I thought I had already taken care of this but I went through Vincom's steps again to root (just to be sure) and now I routinely get a "E-signature verification failed"
The CWM (ver 6) doesn't give me the option to apply from external card, nor does it have an advanced section. I think I am going to wipe the phone again and use the old CWM.
===UPDATE===
I ended up wiping my phone again, going back to CWM 5 and SKYICS 4.2. Wiped everything and voila. Battery is reading 100% again.
Thanks TJ for your assistance and patience.

How to Wipe Battery Stats On Nexus S

Hello guyz,
I want to wipe battery stats of my nexus s but there is no option like that in cwm>Advance>Battery Wipe Stats
Can anybody help me in this?Thx

don't ... it's quite useless
( there are tons of app,but u can also charge to 100% and battery stats are deleted automatically, or pull out battery, anyway it doesn't affect battery life ... )

Yeah as the last poster said, a Google person came out and busted the myth that wiping battery stats helps in batterylife/precise readings. The stats wipe on their own after each cycle, I don't know exactly how long those cycles are but most likely after full charges/a day or two etc.
Its best to just let it be and it will calibrate itself.
But if you really want to the batterystats.bin file is located in the system or data folder in the root directory, delete it and it will automatically start a new one.

I wan to wipe battery stats of my nexus s bcaz it's not fully charging to 100% Only charging to 98% and saying fully charged.Today i have flashed a new rom and now it's charging to only 95%.What the heck problem it is

Some ROMs have a ceiling for charging the battery in order to 'preserve the battery' so it doesn't completely die as fast. So they make it so that it can't charge all the way to 100%
So its not an actual problem on your phone and wiping stats won't help you
However if you still want to be able to charge to 100% you can download nstools which has an option to fully charge

Ok guyz thx for ur post and ur time.

Batterystats is nonsense. Batterystats are wiped every time you charge your phone to full or almost full. It makes no sense to wipe battery stats with an app. Fully charging your phone and letting it turn itself off because its empty works best!
Me Gusta!

I used an app called battery calibration..

I had the same issue when i was using stock google ICS/JB ROM.
It disappeared when i made the switch to CM.
No need to delete batterystats.bin

Charging time

Hello, I have bought rooted htc sensation and am very upset with it's charging time, it takes about one hour to charge 10% of battery. Example today I started charging it at 7:05 when it had 49%of battery. Now it's 11:06 and battery shows 88%. I know it's not normal. Is there any way how to fix it, or maybe test my phone somehow? Should new battery solve this problem?

Try deleting battery stats in recovery, this can lead to misreading. Also, usually the battery is higher than the percentage shown, just reboot your phone and you'll see how much battery is left (one time it showed me 2% when I actually had 45%, but that's because I put my phone in a -20C freezer).

Try the 'battery calibration' app on the play store, I believe it can do this. But keep in mind that the battery an lose it's calibration with time, and even if uncalibrated, it will last about the same (although the OS starts saving at 30%).

Battery calibration didn't helped. But I noticed strange thing:
My friend also has htc sensation and his battery fully charges in 4hours. I exchanged my battery with him and charging time is same! He fully charged my battery from 14% to 100% 4 hours and my phone still charges very slow. I started charge his battery from 44%, at first it was charging very fast, but after 4hours it charged only to 88%. I rebooted phone and then it showed 100%. Where is the problem? My phones charges very slow with any battery. I don't want to reboot it every time to show 100%

What ROM do you have? Is it stock or other? I need about 2:30 to be filled in A1-7 4.3 ROM ... Have you tried the USB and what are the results? Maybe make some other rom, so if you do not work fast carge, change the charger and battery

But after a reboot the battery shows its actual percentage.

In the end you still have a fully charged battery, it just do not show well while charging?
I read somewhere in albinomena tread to show that when the phone is fully charged, you need to leave for an hour on the charger.

Wiping battery stats won't help you.
Put your phone to charge overnight, discharge it completely. Do this for a few days.
Do not wipe battery stats, or you'll have to go all over again.
Happy to help.

Phone is stuck on a % and does not charge

Ok so my N5 is stuck on a % that I plugged it in to charge it and it does not move from there! U have rooted stock 4.4.2 and franco 23.
ps: The only way it fixes is I have to discharge it with 1% or more and then it charges normally.

Wipe cache and dvalik and reboot see if it helps

Is it *actually* not charging, or is an app/widget telling you that? Look at the battery statistics and see what the actual battery level is at.

No apps or all. Even overnight like 8-10 hours it stucks on a specific % and does not drop or chargers. It is like it draws enough energy to work... I am using the original Gnexus charger which is 1.0A and it charged nex5 for like hour and a half when this stupid error does not occur.

i'd flash the stock kernel, wipe both caches and watch it to see if that resolves the problem

battery issues

for the past 2 months the device has been shutting off at 16% when i plug the device in then it states i have 31%....this is puzzling.I have wiped cache multiple times as well.

Battery don't need calibrate, Android need calibrate files about usage. So if u want calibrate battery stats/files discharge phone to 5% and after charge to 100%. Is recommended not use phone when is charging. After full charge reboot phone and u will have calibrate files, your usage is calibration. Sorry for my English
