Does the phone have an ability to shut off charging once the battery reaches full capacity (eg. my old HTC Touch Pro 2 had it where once the battery hit 100% charged, the AC would no longer provide power to the battery and the phone would run off AC entirely instead [but the battery would still very slowly lose a charge]) or will it continually keep providing power to the battery then to the phone (which essentially charges the battery continuously, reducing its life)?
In other words, does it charge like this:
1. AC --> battery --> phone
2. AC --> battery (when it hits 100%) --> AC --> phone
3. AC --> battery (when it hits 100%) --> battery (powering phone)
I ask because I know if you're constantly keeping a rechargeable device plugged in, it will reduce the life of the device. I'm not sure if this device can recognize that the battery is full (once the LED goes green from amber) and disable battery recharging.
Yeah it cuts off the power supply once 100% charged, and the phone then runs completely on ac.
But it still does reduce the battery life of the phone.

Thanks! What do you recommend? Removing the phone entirely from AC once I hit the green LED/100%?
yes.. remove immediately or battery would get swollen.. happend on my dads note. used to keep on for charge overnight :banghead:

Battery would get swollen? Do you mean hot because of the constant overcharge?

90%, because sometimes the battery indicator shows wrong values.
Oh and NEVER leave tour phone charging overnight.

You should never fully discharge a Li battery; to recalibrate, wait until your phone is fully 100% (not just until the LED turns green), wipe stats and then unplug and use as normal. It will take a few days for the OS to recalibrate but after a few cycles of dropping it to around 15-20% and bringing it back up to 100%, you should see an improvement.

Exactly right. Be careful, some people will tell you to discharge until the phone powers off. But this is risky, and not necessary. Over-discharge of a Li-ion battery can result in the battery no longer taking a charge, forcing replacement of the battery or recharging using a special battery meter with a "boost" function, which most people do not have access to (often easier just to get a new battery). The batteries have a safety circuit which is designed to prevent over-discharge, but its not 100% reliable. People on here have reported dead batteries on the Vision and other phones (after letting the battery discharge until the phone powered off), probably for this reason. Plus, the battery meter on phones are really not all that accurate to begin with, so discharging fully is not going to be any more accurate than discharging to a safe 15-20%. So zero reason to discharge the battery fully.
Ok...thank both of you 4 your information

I'd like to check if its safe to leave my phone charging for 7+ hours. It will be nice to leave the phone charging as I sleep.
But without a timer this would easily mean 3+ extra hours of it being left charging when it's already fully charging.
Will overcharging on a daily basis lead to any problems?
Thanks.
No. Charging overnight is fine.

Theses phones stop charging once they hit 100% it very safe did it with my desire for two years.

The phone stops charging at 100% and lets it drop to 95% before starting to charge again to combat overcharging.
Many thanks.
Thanks given to all 3 of u!
So u people say that custom Roms can be safe when we over charge
By automatically stopping it or discharging a little bit.
I use a galaxy note.however replacing it with a htc one...
I won't mod them by installing custom Roms and all..
What if I do the same wit it now?(overcharging?)
Its the same for stock.
Its not possible to overcharge it. And the ROM you are running will have no effect on this behaviour.
Its all controlled by the charging circuits inside your phone.
They read the amount of millivolts that your battery is giving out.
These are not exact numbers (just an example)
Low battery - 800mv
You put it on charge
When your phone reaches 2000mv - full battery
it will stop accepting voltage in
While it is still plugged in your battery can fall to about 1940mv at which point it will start charging again until it reaches 2000again.

Ok cool, I see. Despite what you said above, I also have been doing this for a short period but when i get up in the morning, my htc one m8 are hot at the back. When i remove the charger the heat disperses. Can you tell me if this is normal? Also my phone are using 4.4.2 which is not the latest update.
Hey guys,
I read all the solutions but none of them works (somebody just says to reboot the phone, somebody says that it needs a charging cyrcles etc).
I have myd esire that stops charging at 99%.
If I unplug the AC (after like 12 hours), and then I replug it again, it finishes charging at 100%.
is there something I can do?
Had you done the wipe battery states already or you hadn't done it?

Time for some myth debunking I see.
Hey !
Actually, the charging process of most devices is to fully charge the battery up to 100%, and then to let it be discharged as if it were disconnected down to 90%, then charge it again back to 100%, and then let it discharge to 90% and so on...
This system allows to preseve the battery's lifetime because li-ion cells (and cells in general) don't like to be charging even at 100%
there is DEFINITELY something wrong with my phone: I had the battery at 28% (I read the percentage with battery calibrator), and now, after 1 hour, is at 35% :O
Charging a battery is obviously a chemical reaction - if you unplug it, the reaction stops, plug it in and it restarts.
Meaning:
If your phone stops charging at 99 % the chip on the battery reports its fully charged. If you un- and replug it the process starts again and the battery needs some time to send a fully charged report. If you check your battery the its somewhere between 98 and 103 % of the rated capacitance your battery is fine.

Delete your battery stats, charge it an entire night. Do you use the genuine charger? If the battery is still not fully charged then its most likely the battery. If it charges to 100% - but very slowly - its your phone or the charger.

I deled the battery stats yesterday night, but nothing changed.
the battery is genuine and new!and by new I mean that I bought it two days ago...
I don't use the geuine charger, I have the USB on the wall, why?
Try charging from a PC usb port instead of a wall charger. I only have anecdotal evidence, but I find that the battery lasts better when charged slowly from my PC than when charged while plugged into the wall (true for my Sony X8, also appears to be true for my Desire which I've had for less time). It takes probably 5 times longer to charge on a PC vs. the wall plug which I assume has something to do with it.

Sorry I'm a noob. Wut is dat ?
Kinada new to this. But
It is ok to charge the Samsung stock gsm battery at any percentage or should I wait till it low to charge it??
Like if I'm at 30% at night and need full battery for the next day, should I drain it to 10% ish or just let it charge from 30%??
Would it shorten the length of the battery or harm/damage the battery in any way??

doesnt matter with lithium.
Samsung Galaxy Nexus uses Li-Ion battery. So it doesn't matter if u charge it any way u like.

yes it does.. overcharging the battery is not good. it may decrease its capacity. it is always recommended to unplug it when your phone is fully charged
- It is best to keep the battery between 20-80% and never fully discharge it except for the first time just for calibration
- It is preferable to use the pc for charging (slow charging is better)

What you'd stated is true but doesn't the galaxy nexus have its own safety for this where it stops charging and runs off the battery til it drops to ~98-96% and then charges back up ?

Is slow charging really better? In my experience, when charging from AC, the battery lasts longer than when I charged it from my laptop.

No, the charger will stop charging when the battery is full. If it didn't, an explosion would awaken you at night....
Hi all.
My GNexus's battery charging but the battery stays at %98 and not charging. I've tried another charger and plug but situation the same :/
But I'm trying charging on pc via USB cable, In this way charging smoothly (%100)
What can i do?
Its normal.

If this is a normal why the other phone (other gnexus) charging fully every time?
You could shut off your phone, and load it without android running, after 3h it should be full
And then try and boot up
Happens to me from time to time I noticed if I pull out the charger and put it back in (that's what she said) it will continue to charge the rest of the way

Could be your battery limit on your settings ,if you have trickstermod see if your battery limit is 98 (ps .its suppose to make your battery last longer in the long run )
Sent from my Galaxy Nexus using xda app-developers app
Even if your phone shows 100% it'll go back to 98-97 in a few seconds, it's how the battery is made, theres some technical info. about how/why it's like that but its simply how it's meant to be charged and is perfectly normal =]
I have a few other devices who charge to 100% and stay at 100 for like 5-6 minutes when used. I hate when I wake up and see my phone say "Charged - 98%"
Sent from my Galaxy Nexus using xda premium
This seems to be the way the Gnex calculates it's battery. I can't ever get 100% unless I practically force it too with unplugging it and plugging it backin. In ICS roms on my XPlay i could wake my phone 4 hours after unplugging it and it would say 100% (after little to no use of course). I still got similar real use battery life to my Gnex though.
The battery percentage is a calculation, not a physical amount of juice your battery has.
