Is it worth doing or a bit pointless?
Sent from my LT26i using Tapatalk 2
I'd say that if you have a bad battery life it is worth holding the volume up and on/off button till u feel the phone vibrate 3 times, then discharge it and charge it to 100%. Why else would anyone do it?
Just cus it's an option in CWM i wondered really.....

Anyone else have this problem, where the phone will automatically shut off. When it does that, I enter bootloader, and it says battery is low, did a battery wipe in recovery, onto to see the battery, which was at 40%, now at 2%... Any reason why it's giving such a discrepancy....
Running Energy Rom with stock kernel.
Download "Battery Calibration" from market. https://play.google.com/store/apps/details?id=com.nema.batterycalibration
Charge your phone until it says 100% and the light turns green. Unplug your phone. Plug it back in until the light turns green again. Open this app and calibrate your battery.
Should fix the issue

That is a nice trick, but won't fix incorrect battery readings.

funny thing, i tried that....
it likes to stick at 60% for like 7 hours, only to drop the ball and then show out of battery after it shuts down....
could always treat it like a laptop battery to calibrate it, Charge it fully, let it go dead and keep the battery dead for at least 6 hours. Charge it up and let it stay charged for several hours before unplugging it.
Or try and take the battery out, hold the power button for a few seconds, reinsert the battery and try again. These things sometimes help on laptops, figured it couldnt hurt here.
My solution is just keep it plugged in pretty much most of the time, and drain it weekly....
I regularly calibrate my battery weekly. Although, the recovery I use displays battery percentage and it's often different (more accurate) then what is displayed on my battery icon.

Why is touch wiz instructing me to do this. . Does it hurt the battery if I leave it in for a while?

It is saying unplug the charger from the wall to save energy.

No it does not hurt
I have a sgs1 that's 2 years old and I charged her up every night for those 2 years (leaving phone pluged in over night)

well hypothetically if you leave it in for like a week (unlikely), the battery gets weak but assuming you use it every day that wont happen! they probably are helping people who lack the brains to remember to unplug they're phones... hope that helped!
Once the battery is full, the phone runs directly off the charger like a laptop. You can leave it plugged in until you wake up in the morning for example.

Are you talking about the fully charged notification? Just delete it with root you can use root explorer and just delete it.....
So as soon as I take out the charger the battery goes to 99%. Why is this..

Look, it just does it for everyone. Its not an issue.
Apparently the latest release from samsung doesn't do this any more.
But essentially, as soon as one minisculer, tiny, mini, minute little bit of power is used, like 1 millionth of a milisecond of an LED light or screen on or data connection etc, its no longer truly 100%.
So if its 99.9999999999999999999999999999% battery, it shows as 99%.
I guess Samsung changed it to change to 99% later in the newest release because everyone whines about it. About 5 threads a week here.

the new uk unbranded firmware charges to 100% and stays on 100% when i take it of charge
Regardless of what the indicator displays, ion lithium batteries never charge 100%.. once it reaches 100% it discharges to avoid over charging..
It's not an issue..

Calibrate your battery....cwm, wipe battery stats, reboot, drain battery to the point where your phone won't turn on, charge whilst phone is off, when your phone says its fully charged, remove charger and plug back in to make sure, power on, drain battery again and repeat the process from charging with the device off.
Do that around 4 times. And then maintain your battery by not charging everyday, run your battery completely dead around twice a week. Turn wifi/data off when not using it, auto brightness, bluetooth off, minimize the use of widgets and lwp

Thanks for being so informative. I will do all of that. Is there a chance my phone will screw it self by re calibrating via cmw?
Also I trust your word about draining the battery twice a week, but I'm also curious as to why I've read in some places that you shouldn't let your batt drop below 10%. Is there a specific reason or is it just a false piece of information ?

Reset the stats does no harm . Drain twice a week is pure bull****.

Well, I'm gonna have to disagree with the others on this one. I started at 64% battery, rebooted - still 64%. To ensure this wasn't just a fluke, I tried it a few more times, and tried it the next day after charging all the way, draining it a bit, and then rebooting. Doesn't sounds like it's anything to worry about though, just thought I'd add my experience.

Let the battery drain out until it's empty, then charge to 100% with tablet off. After full charge, turn it on and let it charge additional 30 minutes-1 hour, then unplug and reboot and see if this fixes drain issue!
