Hey guys, it seems as though right after I installed the 3.28 HardSPL by jocky that the battery percentage displayed on the phone is incorrect. I see that using the Battery program that the voltage of the battery when 50% is displayed is 4V. And that at 4.17V the battery is 70% and tops off charging at that point. I know that at 4V the battery is definitely not 50% and at 4.17V the battery should typically be full 100%. I knew something was wrong and tried turning it off and back on and nothing happened but when I removed the battery and put it back in the correct percentage was shown. Is there a fix for this? Thank you once again.
everything is fine here ... plus you should have posted this under jockyw's hardspl thread instead of creating a new one !!

Since installing Cognition, my Captivate's battery life has gotten steadily worse, and I'm reasonably sure that the calibration is off. As it is, even with 3G off, I still barely make it to the end of a regular day. Something's very wrong with the battery calibration. I did flash on a less-than-full battery, which is probably what caused the problem in the first place.
For example: A little while ago, I discharged the battery until the phone shut itself off. I was then able to restart from the same battery two more times (without charging), both times showing 3-4% remaining. The phone stayed on a reasonable amount of time with those charges, and shut itself off nicely when it read <1%.
Just now, i plugged it in, turned it on, and it immediately read 17%. It is now draining at a rapid speed, but it still has too much charge to truly be anywhere near empty. My multimeter reads 3.61v on the 3.7v battery, just for reference.
I recalibrated my battery just yesterday, but there is still a discrepancy between the percent when off and the percent when on. I don't believe I'm actually charging to 100% capacity or draining to 0.
Cutting to the chase: How do I completely zero-out my battery stats and actual charge at the same time for an accurate calibration?
Battery calibration that we follow here is strictly for the OS. Battery too has a chip in it that sends the readings to OS. Let ur battery do its charge-discharge cycles over a couple weeks, and see if its adjusted. Try not to delete ur battery stats again n again. Give both OS and battery to adjust to each other.

If you are on the newest version of Cognition with DG's Cog kernel there is some trouble with it. DG knows about it and is working on a fix. You'd know that if you are reading the Cog thread.
ROM-specific posts should go in their matching sticky in the Q&A subforum. Had you looked in there you would have seen the battery issues with the current version and that DG is working on it.
A search of battery stats would also have answered your question about that aspect. SGSTools allows you to delete battery stats easily.
I guess it might have been faulty to assume that this is a general hardware problem, but I'm not using the newest build of Cog. I'll check my version and then read the release log in the thread l, then. In the meantime I'll go through a couple charge cycles before making any judgements.
Please post in the threads already opened.

When I got the automatic update to go from 2.3.3 to 2.3.4 My battery was charged about 30%. After the update was done, which went very quickly, it was almost 60% charged. This sudden jumped seemed awkward to me. I have the feeling that a 100% charge is now actually a 80% charge, because it recognizes the battery as full.
So I downloaded an app called 'battery monitor widget' to see some more battery stats. When I bump charge, I have reached 100% with the following stats:
4200mV
1200/1200mAh
Seems oke, but the first thing I noticed it says it has a 1200mAh battery, while my battery itself says it's a 1500mAh battery. It's on the sticker. Also the Nexus S is generally advertised with a 1500mAh battery.
Can it be that the upgrade messed things up? Why does it see my battery as a 1200 insteed of 1500? I honestly don't know if the problem was there before the upgrade, simply because I didn't question it.
Anyone knows what's going on?
Thanks in advance!
Bump. There must be someone between all these experts here..?
I've emailed the dev and didn't get a reply. Just go into settings and change it to 1500. The highest I've ever seen the battery was 98. I've read other things on this so it isn't an isolated incident. I wouldn't worry about it. Don't bump charge it too much, that might not be good. Charge while off or when it says it's charged, reboot the phone and let it top off again.
Thanks for the reply, but how can you change this in settings?
My battery level indicator displays a higher battery level after rebooting. With an app (Battery Indicator) which is translating level in %, its about 10%.
Rebooting in recovery is also resulting in an higher level, also about 10%.
I'm using Insertcoin 3.4.2 with 2.6.35.14Brickedv1.5 kernel.
Has the custom rom or kernel something to do with displaying inaccurate battery level stats or is this something normal?
Keeping rebooting doesn't deliver me a full charge btw, now that would be something nice
I have somewhat of a similar problem.
I use hyper non-sense 0.5 and today my cell wouldn't charge beyond 99%. I rebooted and only had 92% .
I wiped batterystats before rom flash..
Maybe these issues are somewhat related?
It's known that the battery reporting driver is **** and bugged.
Also, if you reboot, you'll get messed up battery reports than if you power off then back on.

Only wipe battery stats when your battery is charge to 100%
Support TrevE! Fuh Q CIQ!
Ok, thanks for the advice. Good to know not to be too much confident on the battery indicator.
Have found another threads about the battery stats and the behaviour of li-ion batteries also (the search button was gone for a few days, but back at the moment ), reading already...
Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem
So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

Thanks mate! I will try this out! cheers!
Hello everyone,
I have a very unusual problem with my sensation xe. Let's say my battery is at 10%, i connect the charger, it say's charging, but my battery shows that is discharging and in fact , the battery is charging. The level goes 10%-9%....-0% than it jumps at 100% and goes again to 0%. I tried all the solutions here, but i found that nothing helps. I tried, Battery Calbration app from Play Store, I tried manually wipeing the battery status from recovery when full, i tried all the Rom's , new battery, stock ROM NOTHING! Even when i let the phone charge while in recovery, it doesn't show the true % of the battery.
The phone:
-S-OFF
-latest firmware/radio
-1.27 HBOOT
-now running MIUI
Please Help ME!
Still, the same problem :/
Those battery calibration apps dont do anything neither does the battery status wiping. The battery level indicator gets feedback from the sensor. So if you are having problems with the reading battery level, sensor is malfunctioning. If the battery holds i say ignore it. On the other hand if you have some cash put aside change the battery ( preferably get the same one, anchor batteries are of a larger capacity and are generally cooler but i've see people complain about your exact problem with them). No good news from me unfortunately but hope it clears the problem up for you... Cheers
Try to install app BetterBatteryStats, this could indicate the problem. I got the same problem as you and i delete battery data in recovery.
