[Q] Charging issue

So I have a weird charging issue. Anytime I plug in my G tablet it will charge to 96% or 97% and the light will turn green like it has a full charge. It never reaches 100% Can anyone help?
using TnT lite version 4.2.5

My gtab does exactly the same thing, could be normal.

I know this has been brought up before....
Mine does that too... But the battery life is pretty freaking awesome, so I don't let it bug me too much....

It can be fixed if you want. There are threads about this in the general section. Hit up a quick search for battery issues and you will find them. One way is to drain the gtab dead and then plug it in and boot to recovery. In cwm under advanced you wipe battery status and then power down and let it charge to full. May not work the first time though.

Hmm, interesting. If this eats away and bothers me enough I may attempt this, but I agree with the statement above regarding the great battery life regardless of the presented battery percentage being reported when fully charged.

Battery won't charge to 100% on stock phone

hi guys. I'm having a pretty simple problem - my phone will charge up to full according to the battery icon when it's off, and when it is on it says charged on the lockscreen, but it says 96% on the battery widget that I have and as soon as I unplug it it drops to 96% on the lock screen. I know this is a problem common if a tomorrow was flashed with a not full batt, but I haven't flashed anything. I have only rooted. Deleting batterystats .bin didn't seem to do anything.
Thanks in advance. Hopefully it's an easy fix.

No problem for you. It's made to charge up to 96% to "extend battery life" or whatever. Don't worry about it.
Some kernels provide a cosmetic fix that shows 100% charged, but it charges only to 96%. Another alternative is to bump charge the battery (explained here on the forums) but I don't see why you would do that. Not much to gain anyway.

it's safety feature in order to protect battery

That extra 4% - not that significant. I've tried to bump it to 100% (have to wait significantly long), but not much gained in term of extra uptime.

Ah cool. Thanks for the info.
It's not like that extra 4% is a big deal, I was just curious if i needed to recalibrate or not.

Nothing to worry about. Just enjoy your NS with ICS

read here : http://forum.xda-developers.com/showthread.php?t=1040229
and try installing Nexus S charger app in the market, got 100% charged on my Nexus S 4G !!

acutally , for Li-ion battery , if you everytime drain it to 0% or charge it to 100%, would damage it and short its lifetime...

If you wan't charge 100% use a custom kernel or Rom.

What is Offline Charging???

What is offline Charging? I have seen that some ROMs do not support offline charging. If it means that you can not charge your phone when it is switched off,
then how would one charge his phone if its battery is completely drained?

Offline charging means that you are able to charge your phone even if it is switched off. Without offline charging enabled, when your phone is off and you charge it, it will turn on again. For example, in the stock rom, when your phone is off and you charge it, you will only see the battery meter and the phone did not turn on

No offline charging = Can charge your phone, but phone will be turned on (can receive calls and messages etc)
Offline charging enabled= Can charge your phone, when it is off and cannot receive calls messages)
Either way, you will still be able to charge your battery

Yes, but with offline charging, it will cause the phone to boot up again

So let me see if I understood correctly. If there is no offline charging when I plug in the phone it will boot up? If I have offline charging then it will remain off and show the battery meter(or nothing at all)?

Yes! You're right

So you confirm I can always charge my battery even if the phone switched off because it was completely drained?
This is the only thing I'm warried and which is keeping me from flashing a new ICS ROM.
It's not a problem if it boots up again. I can always put it in airplane mode when charging during the night... Right?

Noooo you are wrong ,it does switch on and charges from 0%
i am not lying this has happened to me many times when i come back from school and phone is discharged. i am just sharing my experience

OK so basically all I got from the posts is that you can charge it afterwards no matter what. And I think that is the main issue everyone is worrying about.

You're absolutely right

It cannot be enabled or disabled by user... it'll be enabled by default if the rom supports it, else it'll not...

What is the kernel support?

A kernel connects the application software to the hardware of a computer and is the main component of most computer operating systems. Check wikipedia if you want to learn more about it.
Kernel support now, is whether your kernel supports a feature or not.
For example if you download an app for overclocking you are gonna oc my ass if you don't have a custom kernel which is written to support overclocking.

Offline charging is being able to charge the phone when it is powered off. The stock rom on many phones has this feature so if you totally discharge the battery you can plug it in and charge it up. If you have an aftermarket rom that does not happen when you totally discharge the battery you end up in a boot loop. The phone starts up when you plug it in and it attempts to start. It wont fully boot because it runs out of juice then it attempts to start up again and it keeps going in this loop.
With aftermarket rom's there seems to be problems getting a offline charging mode in them to work properly. I know nothing about coding or building roms in general so i cant say what the problem is or why its there.
So with aftermarket roms you have 2 choices really if you drain the battery totally. Take the battery out and put it in some other charger. Plug it in to a charger and hold down the correct keys to enter recovery (lg optimus one home + vol down + power ) and let it sit in that mode for a minute or 2 then reboot the phone.
Would be nice if the aftermarket phones supported offline charging but there are plenty of ways to prevent this problem and even ways out of it without going too crazy so its not much of an issue anyway.

I have no idea about this. You make me understand what is about offline charging. Thanks

Phone charges but...

So my girlfriends ns4g charges but the phone won't say it's charging
For example
Battery icon won't say charging.
I use Dx battery app and it stopped showing a charge.
Etc.
now when I go into settings under battery it will say charging .
She's worried somethings about to end with the phone. It was random when this started. No kernel or ROM change.
Any ideas or is the phone just acting weird? I've never seen this before.
Thanks

Same thing. Also when it's tuned off an plugged in, it doesnt show the charge icon either. It just restarts. :-/ thanks tho!

Need more info. Rom, kernel, any mods, 3rd party battery, etc.

Skyrocket Battery - Charging Tips

I am receiving a new phone battery in the mail for my i727 since my old one won't last at all.
Do you guys have any tips for me on how to charge my battery so that I keep my charge for the longest time possible without damaging or ruining the battery in any way?

Define 'won't last at all'? How much time do you get on the battery now? It rarely has anything to do with charging, unless you use some crappy charger that blasts high amperage current at it. Battery drain is almost always because of either a wakelock preventing deep sleep, or an app running in the background chewing up CPU, and thus battery. For me there were 3 culprits, 1) some chargers (specifically Apple compatible ones) cause a wakelock on 'vm_bus_present'. If you see this, reboot after charging to clear it and get a different charger. 2) Corrupt media data that causes the media scanning process to continually spin CPU. Clear data and cache for the media app. 3) Bluetooth crashes, and the you get a 'bluesleep' wakelock. Reboot until Bluetooth stops crashing, usually for me it only takes one.
CPU Spy and Better Battery Stats are your friends. See the Battery pinned topic, this is covered in much more detail there.

I'm not sure it matters about my old one.
I just need to know how to charge my new one. Everyone talks about how they charge their battery, and I want to hear how.

I plug in my phone at night, and I unplug it in the morning. I don't think it gets any more complicated than that.

You plug it in and when it says battery full you unplug the cord.

Nothing mysterious about charging a phone. Seems like there were some complex charging rituals way back when but they have since been proven BS. That being said, If you normally run your phone down by mid day because you play with it all morning no fancy charging ritual is going to help you.
