m using this galaxy nexus(not rooted) since last year but after the recent update of 4.2.2, am having some trouble with the charging,after it reaches to 98% it automatically stops charging than i have to plug it in out times to get it charge to 100%..help me out with this.
AW: [Q] problem with charging
let it rest a while on the charger, mine does that too

Actually theres a huge explanation i read about this but in simple terms our batteries are designed to not charge all the way to 100 percent i believe it's been like that from the start .. even if it shows 100 sometimes after a few seconds it drops to 95 or 96 .. there is nothing to be worried about it's just how it's meant to be, hope i helped
It also needs to be borne in mind that your battery will have decreased in capacity after this long. A lithium polymer battery is only capable of a finite number of charge cycles during its serviceable lifespan.
That being said, the practice of unplugging and replugging the phone in order to force that feelgood 100% indication only serves to further damage the battery. By doing that, you're only shortening your battery's life.

I bought this: http://goo.gl/70Els
I'm wondering if it will solve the bump charge issue and will charge the battery fully without having to go through hoops to just charge a battery!!!
I'm tired of being at 90% after ten minutes after a full night charge!
Thanks

Very doubtful. Your best best is the kernel being developed in the dev section with increased charging.
My question has nothing to do with the phone itself because the battery is not in the phone when its charging, it's sitting in the cradle. Nothing to do with the phone itself. Do you think the cradle will charge the battery fully and completely.
Thanks

I've got the charger mentioned as well. I just see it charge the battery "normally" to 100%, and if needed over the next ~xx(x) hours or so, another trickle at low mA will be applied. That isn't the same as this "bump charge" that is always referred to here.
If you turn the phone off and charge, it'll charge just like the charger (Seido) to 100%.
There's lot of good info about LI batteries like this writeup: http://batteryuniversity.com/index.php/learn/article/charging_lithium_ion_batteries
Anyway: I thought the main gripe about the DINC charging technique is not anything about the technique, but that it always runs the phone off the battery, rather than using the USB current when it's plugged in. Most phones use the USB (or whatever tech) to a) charge the battery and b) run the phone. Of course if this is HTC's method, then you'll very rarely unplug at 100%.
The rate of battery consumption, regardless of % starting point is more of an issue for me. Using all the SENSE/HTC/VERIZON stuff is a losing proposition more than not having 1-9% of the full capacity at 'go' time. As soon as I rooted, I dumped every app and service starting with HTC*, VER*, *sense* and battery life improved by a great deal. Yeah, I don't care about social networking (well, aside from a forum or two ) -- But I enjoy most of the other phone functionality.
The charger's fine, it's the battery that troubles me
I have the charger, too. Works fine. Does not require "bump."
But the battery (the 1750) that came with it has failed to impress me much, with a tendency to overheat. Frankly, since I rooted and started using SetCPU to underclock with screen off, I've been using the stock battery.
I'm a new and I don't know if let Arc from x% to 0% batterry (Ex : you are watching movies and listen to music then go to over sleep) and Arc auto turn off --> Arc will be damage ?.
With your experience, would you let me know about this
Thanks !
well from looking at one angle it might cause u serious problem..but if u have an external charger then u can charge and use your phone
dont let lithium batteries to drain till single digits..keep them charging whenever u get a chance
Maybe if you have a custom ROM, my arc s has turned off by itself from low battery and i just recharged until it was strong enough to boot into the homescreen

Prolonging battery pack life
Avoid deep discharge and instead charge more often between uses, the smaller the depth of discharge, the longer the battery will last.
Avoid storing the battery in full discharged state. As the battery will self-discharge over time, its voltage will gradually lower, and when it is depleted below the low-voltage threshold (2.4 to 2.9 V/cell, depending on chemistry) it cannot be charged anymore because the protection circuit (a type of electronic fuse) disables it.
Lithium-ion batteries should be kept cool; they may be stored in a refrigerator.
The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures.
The rate of degradation of Lithium-ion batteries is also related to battery charge level; they degrade much faster when at 100% charge, than at lower charges. Since batteries die if deep discharged (depleted) and since a battery has some self-discharge it is frequently recommended to store batteries at 40% charge level.

I hope that tells you the answer.
if you leave it @ 0% for any extended period you run the risk of it never taking charge again. i have done this to countless (not phone) batteries by accident and i can tell you that it is 100% true.

I didn't know that tnx for sharing.This XDA is a good thing,we find some usefull stuffs here,tnx guys.

so basically, it is dangerous to leave it at both 0% and 100%?

If you let it die it may give you a hard time getting it charged again. It needs a certain amount of power to boot the phone to a state where it can check the battery and start the charger. I have killed mine a couple times and had a few tense hours trying to get it charging again. So it is best not to let the battery die completely

Thanks for your experience. But android don't have any soft auto turn off phone when battery is 10-15% ?
Besides the main battery power, there is also a reserve power when the battery is discharged. If the reserve is depleted, the battery will be completely discharged and cannot be used at all. Prolonged full discharge of the battery will shorten its working life.

so I got Need for speed for my Xperia S (great game by the way, would recommend) the only problem is it is un UTTER battery drain, I'm talking rapid draining even having the screen brightness on low. Do you think the battery is getting damaged by my heavy use in this way? I'm charging it to full, playing it for a good hour and then it needs to be recharged so I plug it in.
cheers

No you are not damaging the battery. Hd games drain your battery. Dont worry it happens with every phone. Please post questions in question and answer section.

How about if I play while the phone is charging, does this affect it in any way, like how with a laptop you should take out the battery if its plugged into the wall to extend the battery's life?

No it wont affect your battery...I have been doing that for the past 10 months

It's a difficult question. From one perspective it's better to keep the phone plugged in because a Li-ion battery has a finite amount of recharging cycles. The worst thing you can do is to completely discharge your battery, then completely charge it again and so on several times. Which is what you've been doing and these are wasted recharge cycles.
But constantly charging your phone will also make it hotter and that combined with an intensive game will make your phone too hot, which might result in some components overheating and a reduced life expectancy.
So I'd advice to keep your phone plugged in if possible, but don't play for hours.
When you compare to laptops, it's indeed better to remove the battery when you're plugged into the wall (keep in mind that the battery doesn't lose its charge though, there's nothing worse for a Li-ion than being completely empty). But there's no phone you can run without a battery so you can't do that . It's also a question of luck. I never remove my laptop's battery and it still easily lasts 2 hours after having it for 2.5 years and using it a LOT (when plugged in mostly). It was just a cheap laptop with a 6 cells battery. Most of my friends that have a laptop that old or older (and also more expensive) can barely keep it charged for more than 10 minutes now.
No,
nowadays you can't damage your battery in any way as I know.
But it is recommended to charge your phone to 100% and turn all notifications off then let it on sleep mode till your Phone is going off by itself.
This doesn't improve the Battery lifetime or something like that but it is recommeded
thanks for the advice everyone
Am I the only person who is some what leary of charging my phone overnight. What I mean is, will it harm the phone any by sitting there fully charged for a few hours or more?
And that raises another question or concern. Does it hurt the device by plugging in and charging a little bit throughout the day or should I let the battery drain as much as possible then plug in?
Thanks for any replies

I don't think it will hurt the battery to leave on charge for an hr or two at 100%. It is recommended to not charge till you are 10% or under from what I read

These phones are lithium batteries. Once it hits 100% or too hot to charge the circuit shuts down. Even my stupid cordless drill does this.

Lithium Ion batteries are in an ideal state of equilibrium when at 50% charge. If you want to maximize the overall shelf life of the battery, do your best to keep it around 50% charge and avoid the extremes like 0% and 100%. Practically speaking this is tough to do. I am frequently near a charger, so I can unplug around 60% and plug it back in around 40%. The high amperage chargers that come with the phone can add 20% in about 30-40 minutes.
So the answer to your question is, the less time your battery spends at 100% the better to maintain the quality of the battery.
LOL, I keep phone on the charger all the time. Then again, I usually have the screen on most of time.
The only danger I can think of is if someone comes out with a kernal that does SBC which can give batteries more charge, but can also damage the battery if overcharged. I haven't kept up on all the kernals, but I don't believe anyone has made any with SBC.

50% is for storage. When in use it is optimal to charge to 100% and recharge between 10-20%, ideally at the 15% warning, which is why it's there. Charging to 100% overnight wouldn't have a huge impact on battery life for a li-ion unless you left it plugged in for several days straight. All newer good quality cellphone and mobile device li-ions have a voltage regulator and charging circuit built in. When the battery reaches 90% the voltage regulator drops the input voltage so its receiving less power til 100% once it reaches 100% the charging circuit opens and stops charging the battery, once the battery begins to discharge again while plugged in the voltage regulator switches to "trickle" charge mode which puts back a small amount of power every minute or so. When "trickle" charging the input power is so low the battery can actually drain while still charging if its being used. These are safety measures to prevent damage to the phone and battery and lessen the risk of the battery exploding, but it also helps prolong the life of the battery by preventing it from constantly overcharging if you forget to unplug it or charge over night. Hope that helps explain a bit about how charging works. Its also better to charge the battery at lower amperage outside of the device. Optimal charging for a li-ion is around 750ma on an external charger or while the device is off.
I like to break stuff!

This. These batteries should be above 70 precent or so as much as possible to remain efficient. Also never let it die that decreases life span.

My battery in my ZL drop fast, it is charged at 100% for several hours, when I unpluged the electrical socket, it's at 99% in less than 3 minutes. My iPhone 4s will last for half a hour before drop to 99%. What is going on with the battery life?
Sent from my C6506 using xda app-developers app
Well, as i have readen several battery care threads here in xda, the charger, when the battery is full, to prevent overcharging or something else that may damage the battery, (correct me if i'm wrong) it stops charging until 99% or 98% and it charges again to 100% and then it keeps doing the same all the time until you unplug the charger (just in your case that you disconnect the charger when it's recharging again when it's almost full) That may be why.
Hope this helped
Sent from a phone >.<
That is strange because I do not see while charging when it hit 100% to go back to 98 or 99%. Not even my iPhone when I got it did this. (I sold it)
Sent from my C6506 using xda app-developers app
It damages the battery if you charge it to 100%, that's why most phones stop shortly bevor the battery would be completely charged. So if it shows 100% it is not really at full 100, that's why it drops right back to 99. That is also why it takes less time to go from 100 to 99 then from 99 to 98.
The iPhone does the same, it just stops at 99 and tells you it would be at 100 (it's actually cheating 1%).
These methods are build in because people love to charge till it reads 100, so they don't damage the battery doing that.
Also, remember the numbers you see is not really the true charge of your battery.
