[Q] full battery charge only reaches 98% after 8 hours

Hi i dont know why my battery isnt completely charging! or the battery charger info is broken! anyone else not charging to 100%?

It probably hits 100% then starts draining slightly to keep it from over charging. Mine gets to 99% then I unplug and replug it and it hits 100. But that has happened with a lot of devices for me.

Happens on my evo as well. You can get around it by flashing a kernel that does trickle charging which I'm sure we'll get for the tf sooner or later.

I would NOT use an sbc kernal on this battery, they are known to shorten battery life. Cell phone batteries are a dime a dozen, this thing is both non-user replacable and most likely not cheap.

Pretty sure its a lithium ion battery inside and you shouldnt overcharge those. You're best off keeping it between 30-90% and doing a drain and full charge once a month to prolong its life. The charger should stop charging when the battery is full on it's own anyways if you do leave it plugged in. I think it's a European law to have that as a safety feature, probably an American law for this too. So if the charger is staying hot a few minutes after your device has hit 100% charge, you've got a problem. Mine does get to 100% but yes it takes a while to top up, that's just the way these batteries operate.

Infuse charging stopped

I had the infuse on the AC charger the other day, when I took it off, it had a message stating charging stopped because of battery temperature. Now battery will only charge to 35% no matter how long its plugged in. Also when phone is off the charger, phone is getting very warm to the touch and the phone is not being used. Do you think I need a new battery or is the charging circuit messed up? Thanks for any input!!!

If your able to plug it in and it shows it's charging then there is noting wrong with the circuitry. Your gonna need to replace the battery.

A new battery is much cheaper than a new phone.
Batteries heat up as the internal resistance increases over time. As Axiomkid suggests, get another battery. Do it soon. Old (or defective batteries) overheating run the risk of shorting, leaking, or exploding.
Better yet get two batteries and maintain them properly ie discharge to 10%, recharge to 100%, then swap out with another battery and let the recharged battery cool down.

Tried a new battery, it charged to 100%... but drained 50% in one hour. When I charged it again same problem is still happening. Thanks for all that helped.

You might need a new charger too. are you using the original Samsung charger? Try charging it from a PC too. The 50% drop in the charge could be a calibration issue too. It would improve that reading over the first few charges with the new battery.

yes i am using original charger, i have use a captivate phone charger as well. i think they are both the same. i'm thinking something is wrong with the phone because after charging and taking the phone off, the phone is getting really hot without being on the charger. like the phone is being used but it's not. could maybe the rom cause an issue like this? i'm thinking maybe trying to flash the phone with a stock rom and see how much the battery drains

Problem solved!!! Reflashed ROM and all is good

Glad to hear your problem is solved! Was that the root cause with your first battery as well?

So whats the best method for a first-time battery charge?

Do i let the phone shut off from the battery reaching 0%, then charge it to 100% and be on my merry way?

I've read multiple theories, but I think u should take it down out of the box, then shut off and charge to full...I remember ASUS recommending that to a media outlet when the Transformer 300 came out a few weeks ago...so that is what I am going to do when I get mine.

Thats exactly what I did, I let mine completely die and then charged to 100%.

Be careful with how you charge the phone, rather with how low you let it get.
Depending on how technical you want to get about it purposefully letting a battery drop to absolute zero can cause some odd chemical reactions that while not immediately evident can some times shorten battery life.
I would recommend taking it out of the box and using it until it is low but not dead. Maybe 10 or so percent and then either turn it off and charge it or leave it on and charge it just do not pull the plug on the charger until it is at 100%.

This.
Full battery cycles are not good for long term life of Li ion batteries.
Also, its unlikely, but occasionally happens where discharging the battery to shutoff will render the battery unable to take a charge. The safety circuit on the battery is supposed to prevent this, but its not failsafe. I've seen more than a few reports on previous HTC devices where this happened. And since the battery on the One X is not easily replaced, the result can be disastrous.
The battery meters on phones are not very accurate in the best of circumstances. No need to drain to shutoff, 10 or 20% is fine. No value added to draining to shutoff, and the consequences can be very bad.
Drain to 10% or even 20%, charge to full, repeat 2-3 times. This is done just to calibrate the battery meter on the phone. Its a misconception that you can somehow increase battery life by "conditioning" the battery. But modern Li ion batteries do not suffer from memory effects, and conditioning only works for older tech NiCad batteries.

I do the same thing for all of my phones.
1. Activate and mess the heck out of it until it dies completely.
2. Charge it up to 100%
3. Mess the heck out of it again until it dies completely.
4. Charge it up to 100%
5. Mess the heck out of it again until it dies completely.
6. Charge it up to 100%
Then use it normally

Mine came dead! it didnt even turn on. so I'm charging it now

How do you tell if the phone is charged to 100% while off?
While on, my battery percentage doesn't seem to go past 99%. Is that correct or is this last 1% just taking a very long time?
Update: NVM last 1% just took forever. LED does turn green when fully charged.

The LED will turn green once it's 100%.

Don't worry about letting the phone die and charging it up to 100%.
These batteries don't have a "memory" like older phones

Mine came dead too. Charged it to 100% and now been using it and so far have 36% on 3h 9m on battery.
Screen at 84%
Does the battery life get better? Because it seems to be draining rather quick. Even though I have screen brightness less than half.

@Maroon Mushroom, Correct these lithium batteries dont have memory effect, but over discharging them will shorten its life.
I dont want to sound like an expert, but discharging the battery until it dies is not recommended. It will affect battery life/performance.
A couple of good references here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
http://batteryuniversity.com/learn/article/discharge_methods
http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table

Ya, we use Lithium Ion (Li-Ion) batteries now which dont have a memory. The older Lithium Polymer (Li-Pol) batteries did have a memory and needed a certain charge method to get the longes life cycle out of it.

Awesome, thanks everyone
I turned it off at 20% and wen't to go buy my MicroSIM (ugh...) cant wait to play with it tomorrow

Why would you buy it? Pretty sure they would give one to you for free

bought it off Kijiji
It's offered by Rogers, but i'm on Telus

Hmm, i hate the idea of letting it die completely. But what i've always done is turned everything on and ran it through a low-powered usb source so it has a charge but the battery is still draining. So even if the battery runs dead it has power via USB plug [make sense?]. Usually having everything on [i do mean everything] and downloading a torrent so the internet is constantly under use. Then again i'm not sure how the One X will work out for this, but thats what i'm planning .

guys its lithium...u cant drain it to 0...even when android shuts down your at around 3.6volts. thats definetly not 0volts. no memory and android wont let you ruin your battery...so charge however whenever.
im qualified in lead acid. ni cad. nimh and lithium batteries. trust me..u cant hurt it unless you short it! !

What "method" do u use to charge your Captivate

Hello !
I have read several articles in where people use different methods to charge theyr battery.Maybe it has been talken in XDA too but i havent found nothing that regards charging
How do u charge the battery ?U keep the level from 90 % to 50 % and once a month u fully discharge and than fully charge ?
Or u fully charge it after it shuts off cause of low battery?
Thanks

I'm a bit of a battery abuser, I tend to charge randomly when I think it will be under heavy load such as long drive in the car listening to music I will plug it in with my cigarette usb adapter thingy..
Most other times just plug it into my laptop. My habit for discharging and turning it on until it dont turn back on is maybe every couple weeks to a month if I remember to. Bout that time is when I start cycling out old apps I don't use and just maintaining clean phone status.

...Wall charger every night, all night, while still on, while I sleep. Been doing it this way for 2 years and still using the original battery.

I just charge it whenever it's anywhere between 40-50% and have access to an outlet.

I use USB to charge my phone I plug it in at night around 9 and it's good around 10am then I unhook it. It stays good till about 6 or 7 pm

Lithium Ion batteries don't have memory effect, so the only reason to run a complete drain and recharge is if the battery fuel gage needs calibration.
I leave mine on the AC or USB charger everynight. The Captivate's power management chip reduces the charging current when the battery approaches full. After becoming fully charged, it stops charging for an hour or two, waiting until the voltage has dropped about 0.1 V, then resumes the small trickle charge until full again.
You want to avoid getting the battery too hot, because that will reduce battery life (life= number of battery charge cycles). I have an alarm set in battery monitor widget (bmw) when the battery temp is 45 degrees C or higher. you can get bmw or other battery tools on Google Play.

It is my second time that i fully drain and fully charge my battery.
It is wrong what im doing ?

I don't think of it as right or wrong. You don't need to drain it all the way or charge it to 100% if it is not convenient.
I put my phone on the charger at night even if the battery is 60% or more full, with the phone on. I want it at 100% in the morning. During the day, it often gets charged while I am driving or when I am using my laptop. Is is seldom fully charged during the day, and it rarely gets drained all the way.

Yeah, and you want to give 'em hummingbird food for faster charging and best compatability with the captivate's cpu. With this charging method, you can even hear the hummingbird hum if you put your phone in a conch shell and hold it up to your ear.

I have four batteries for my Captivate, because the original seemed sorta crappy, and I found supposed-OEM batteries pretty cheap on Amazon.
My micro-USB port seems to have taken a crap, and the phone will no longer charge via that method. So basically, I have an extra-battery wall charger going all the time, and I swap batteries whenever the battery in the phone dies.

I just connect the usb cable port from my Xbox to the phone when I'm at the man-cave table. At night to my computer's usb port since it still power's up when the computer's off which is convenient :laugh:

[Q] Charging decharges w/data on

My phone's battery goes down if it's charging and the data is on until the phone dies. I'm using miktouch and Hyperion's extended battery. It also doesn't seem to charge fast at all (12+ hours). Once it's "dead"it will power off, then randomly go back to 100% battery (orange light to green light).
Anyone else have this issue?

First guess is you have a defective battery. Draining while connected to the charger should never happen with a good battery.

I guessed as much too. These Hyperion batteries go bad quickly. I've had five since January.

With LiPo batteries there is the danger of explosion/fire. I have an Anker universal charger and note that the output when plugged in is 4.2V. However, USB ports output 5V, so I would think the Anker battery can tolerate that otherwise you would not be able to charge the phone by plugging into a USB port.

I hope so too.
So, brand new anker and the battery still decharges when plugged in and goes full charge once the phone is off. I'm thinking there's something broken with the phone and not so much the batteries.

From a lot of the comments in this forum, I suspect the phone has a charging circuit controlled by software rather than hardware. Before you do anything hardware drastic, you might try flashing a different kernel.
Also, you report that the battery leaps to 'full' when you disconnect the charger. Have you tried measuring the battery voltage physically with a multimeter to see if the battery is charging at all. Should be 4.2V when fully charged. Something like 3.6V when empty. Obviously if you put the battery in for half an hour and the voltage goes up, it's charging no matter what the UI says!

I've not tried either of those. I don't completely understand what the kernel is. I'm using Miktouch rom, but I don't know how much that has to do with the kernel. I know the battery is being charged because if I leave it plugged in for a good 8 hours it holds its charge for the day. And if I leave it plugged in for say, half a day, and turn off data/wifi, it will slowly show increased charge, like a percentage per half hours of charging.
What do I need to know and do to flash a new kernel on here?

Your the only one of my users to ever have this issue, including me. And the doubleshot was my last device before going Nexus last February.
What I would do is:
1. Backup all your user downloaded apps with Titanium Backup.
2. *Do a full wipe from recovery*
*Wipe data/factory reset
*Format system
*Format Data
*Format cache
3. Flash MikTouch and reboot.
4. Once rebooted don't go cramming apps and settings back into your phone just yet. Make sure its going to charge and drain like its supposed to. If all is well, then start 1 by 1 with your apps, making sure each of them are not causing your issues. If all tests are passed then something in the ROM its self went stupid.
Sounds like hardware though.
