Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?
Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..
True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.
Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.
As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.
Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.
frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....
FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

As topics says and like your battery is under %20 percent approximately how long does it take to get it fully charged
About 1.5 - 2 hours
Mine seems about the same, however if your using the phone wile charging it takes a lot longer, which is strange because there should be enough current to charge and use simultaneously.
1 hour 45 minutes from 25%, also I have juice plotter installed and theres a widget that you can put on your homescreen that changes from time left to how much time it takes to charge when it is actually charging which is kind of neat.
ty i think my phones charge time is increased will try tonight again

But seriously, about 3 hours from empty to full on the charger that came with it, and about 2 hours with my 2amp galaxy tab charger.

True when I charge my GS2 with my Galaxy tab charger its dramatically faster.
._. there must be something wrong with my gnote then ... it takes around 4h30m to fully charge from around 10%... and even longer if using phone at same time...
I had several smartphones and this one is the one with the worst battery ever ... my dell streak's battery charges faster and even tho it also has a 5" screen, its 1500mAh battery lasts longer with the same usage.
Yesterday my gnote battery took 3h30m to go from 100% to 13% just from playing 2h30m of games and 1h browsing... innaceptable! and I do use betterbatterystats and I have few wakelocks that could be draining battery...
This phone charging scheme is really crappy, as I understand from my use, while charging instead of the charger powering both the phone and the battery at same time, I think it only charges the battery and the phone is always powered by the battery alone...
I din read about it yet, but I almost sure the gnote works like that, cause if i use Skype video call for example, i only get a 1% charge increase around every 10mins, which is really ridiculous ...
plus, while with my other smartphones I could take out the battery while charging it and the phones would keep powered, same thing doesn't happen with the note... battery off while charging, phone also off, which can only mean IMO that the phone is 100% only powered by the battery even when charging...
Besides making it take longer to charge, won't the battery life also decrease that way?..

Whats your way of keeping your nexus 7 battery healthy? I wanna keep it as healthy as I can for as long as possible. Nothing irritates me more than having a battery lose its charge faster and faster every day. Just to be clear im not asking how to prolong battery usage between charges; I'm asking how to keep it from losing its charge quicker and quicker when the power usage is relatively the same. One thing I do know is once it the battery hits 100% to take it off the charger. One thing i have heard is try not to let the battery dip below 50% and rarely let it completely discharge but I have also heard to ALWAYS let it die out by completely discharging. Feel free to add to the myths, folklore but preferably facts on how to keep the battery healthy and holding its charge very well
N7 has Lithium polymer battery, right?
Well then read about it https://en.wikipedia.org/wiki/Lithium_polymer_battery
But from what I heard: rather charge it then let it drain below 30%, don't let it charge too long, and so on - probably the same stuff you heard or read yourself
but that's something that upsets me: no chance to replace the battery. Used my DHD for 2 years and after those 2 years the battery was just ****ty. Replaced it, works like a charme. On N7 or TF300T there's no chance to replace the battery. Right now I'm using TF300T very often when I'm not at home, so even with dock and tablet it'll most probably go below 20%...well if that's bad for my battery, then I don't know what to do if it doesn't last an entire day :-/ (though that'll take some time)
Certainly I wouldn't let the Nexus battery completely drain but maybe down to 5 % then fully charge

You can change the battery on the nexus 7. Its actually relatively easy and simple to do so. I havent had the need to replace it but I did have to disconnect it. Just pop off the back with your choice of apparatus. I used a small flat head that i could wedge between the sides but a guitar pick is another popular choice. Then just disconnect the wire and take the battery out! no screws just slight pressure holding it in. right here is a guide with pictures showing it step by step.
What I would do is time my charges. In my experience, my Nexus 7 gets fully charged in 2 and a half hours from 20% battery. I then take it out immediately so that in won't get hot(sometimes it does, and also to save energy.:good And also, if after 3 days my battery is still 50% or above, I drain it to 20% then charge since Li-ions tend to not want to get not drained often.xD
Charge early and often and keep out of extreme temperatures. It boils down to that.
If you can, charge it nightly. Try to avoid discharging below 20%.
And a little myth busting... There is no need for you to manage its charging cycle, it will do that itself. Charging a LiIon/LiPoly battery partially is NOT a "charge cycle".
If you're actively using your Nexus 7, just charge it as often as is reasonable, nightly should be just fine. If you're NOT using it for an extended period of time, discharge it to 50%, turn it completely off and store it in a cool (20c/70f range) location.

My advice : Charge it when it's between 20%-30%. That's the ideal charge point. Any lower and you're just damaging the battery and any higher is just a waste. As for immediately plugging it out once it hits 100% is utter bull. You see, these modern day batteries found in most phones/tabs have their own resistors which decide how much power enters the battery or if it should enter at all. Once a battery hit's 100%, the resistors kick in and block all incoming power. The "discharging" many believe to happen if we over charge beyond 100% doesn't exist. What happens if you leave a phone or tab alone idly ? It discharges like always. Same thing here, which is why you see your battery bouncing from 100% down to 97%. When that happens, the resistors will allow power back in and thus charging it back to 100%. So you can leave it charging all night and not having to worry about it going beyond 100%. It'll get it's own sh!t together .
So bottom line :
1. Charge when it hits 30%-20%.
2. Don't discharge it (0%) and back to 100%. It doesn't work on modern batts.
3. Don't worry about pulling out when it touches 100% immediately.

Nope. Reboot away. Remember, the only harmful thing you can do and see immediate effects are charging the battery in a very hot enviroment or if you charge it when the battery is 40-50 degrees celcius. It'll either swell up or it'll just catch on fire or explode.
i'm currently using my note 1 as a secondary monitor and it is plugged into the standard charger while doing so. Will the battery be constantly 'zapped' as I use it? or the battery can remain 'like new' if it's always plugged into AC?
Thanks!
Might be,might be not. I did that sometime, even on my laptops without any problems. But the recommended is unplug when it full charged and charg when its 1-10%. I use battery doctor app for trickle charge for long live battery. And btw the OEM stock bettery is cheap anyway. From now till ur battery is getting drain like hell its would be take like 6month to a year.
Just saying ...

It's better to discharge it completely, then recharge it completely from time to time.
Full cycles of charging and discharging keeps the battery healthy for a considerable time.
Sent from my GT-N7000 using xda app-developers app
Also, keeping the phone on charging even after it hits 100% causes the battery to swell. You will not see the effects immediately, but after 4 months, the battery will be swollen on one side. And swollen batteries like to self destruct.
Every battery can be recharged several times[for exm: 500] If you charge it 5 times per day = 100 days battery life. So i think its better to dont remove adapter when battery hit 100%. The new cell phones and laptops got protection and they dont charge the battery when its fully recharged.
This is just my opinion.
Some time ago I did a little research, because I was using my phone as a wi-fi modem for my laptop. Most opinions said, that constant plugging may affect your battery life and best is not to keep it plugged when fully charge too often and for too long.

no it actually does not cause this... the batteries and phones have smart circuitry which prevents battery overcharging.
now fully cycling a battery 1-2 times a week will extend the life of the battery..
As far as I remember from the tech-news, newest energy cells (li-ion and li-poli) shouldn't be charged like the old ones - I mean charge 12h, then empty it completely and repeate the whole process 3 times. I read it on polish site some time ago and they we're also saying, that keeping phone under chargerer can harm battery or even mainboard.
But as we can all see, there are many different opinions about that

Mine did. Swelled a bit on the side, cover used to creak whenever I pressed on the other side
All (reputed) devices that use Li-Ion batteries use controllers that will automatically cutoff charging once the voltage reaches 4.200V/cell.
So you cannot over charge a battery by leaving it on for long duration.
Unlike the older Ni-Cad batteries, there is no memory effect. so there is no need to fully discharge it periodically
In fact, deep discharge of Li-Ion battery will irreversibly reduce battery capacity (Wikipedia -> Li-Ion battery -> Battery life )
Is my charging routine bad? Here is my daily recharging
I let it charge over night. By the time I get home its normally in the 60% or so. So its left on all night until about 7am.
Then about half way through my day I charge it again while I'm at on my office. By then the phone is around 70%. So I let it charge to 100% then move on with my day.
So about 2 times a day I charge my phone. Is this healthy for the battery or does it not matter? I'm trying to get the most out of my battery. I seem to burn about 3-4% per hour with it just sitting on desk. Thanks for any advice!

You are charging twice a day though so you will half as many days until your battery dies. Still a couple of years until it reaches 80% capacity though

Well yeah, but don't worry about it. You'll get another phone by the time you notice a battery drop on this phone.
Ideally you should be charging the phone when the battery gets down to around 40% and charge it to almost full, 97%-99%

I've always felt that the less you charge s phone, the better in the end. And once its done charging, unplug it. So don't leave it charging over night. I have a timer set up so my phone charges only for a few hours a night then shuts off. When I wake up, my phone is usually in the 90%+ range

That's simply not true.
Lithium-Ion batteries are designed to be used - not to be used as permanent storage (thats why batteries in always-coorded laptops die faster)
(storing li-ion batteries should be done at 50% charge, never 100% nor 0%... )
Li-ion batteries should never get below 30% and likewise never hit 100% - The reason why, is because you are stressing the battery the most in the extreme ends... an almost empty cell is stressed when it has to deliver .. and an almost full cell has to charge at higher voltage to reach 100%.
So the best thing you could ever do is to charge from 30% to 95% if possible.
Regarding the amount of charges... with Li-ion you shouldn't think about the AMOUNT of charges, but the SUM OF HOURS that your charge..
so lets say you charge 500 times a year and you in total charge for 500x4 hours = 2000 hours of charging..
the battery usually last for 5.000-10.000 hours of charging ..
The reason why it is so, is because charging li-ion burns the Kathode (or Anode, can never remember) -- and when its all burned off, the battery wont charge anymore ...
Discharging too fast, also burns the Kathode (Anode) !!
Everyone is all over the place in this thread. The two things I will tell the OP to do is not leave the phone plugged in over night, and stay away from 100 and 0% and you will be fine.
But even if the OP keeps treating his battery the way he says, it will be okay. Not ideal, but still okay.
I personally try to keep the phone between 30-80%.
