I have had it plugged into the mains, running tunein radio through wifi and its gone from 85% to 86% in one hour.
If I charge from 10% with phone off it takes about 4 hours to fully charge
If I charge from 10% with my phone on running stuff, it actually never gets to fully charges by the time I finish work...at 6pm
Sorry to keep comparing to the dreaded FruitPhone, but that would charge whilst running wifi and tunein from 10% to 100% in about 2 hours.
I am beginning to think my SGS2 is faulty
i am fiding it takes about 3 hours to charge from empty . It does take a long time indeed but i guess it is what we have to do for a 1650mah battery
3 hours from empty with stock charger .
jje
it might well be a 1650 battery, but it starts to get unusable when it takes all day to charge then a few hours to loose it all.
This phone is the greatest but the battery life just completely destroys it, I am beginning to think I made the wrong choice

Aye... if I don't the bloomin thing would be dead by lunchtime, and I listen to music.
So I basically have to turn it off not use it so I can charge it, how crap is that, owned my iphone a year never had any problems with battery and I always used and charged in its dock.
The desire had slow charging too but snq- fixed this in his kernels maybe we can port his fix to our kernels
btw it's true li-ion batteries degrade quicky when the heat up (or completely charge or discharge)
From 30% it took me one hour and a half to fully charge..
I recommend to download battery mix as it takes very good statistic on the battery life and one can tell exactly how long it takes to charge and discharge

just for the record all Lion batteries in phones never fully discharge or recharge, as there balanced by a balancing chip.
when you get to the likes of 0% you actually have 20% charge, thats why you can power on the phone but it will immediately switch off again. like wise, charging you never reach 100%, it's more like 89%, again because of how Lion works.
if you fully discharged and fully recharged, well put it simply you'd have a lot of exploding phones, fire and chemical burns...
Interesting!
My phone charges in about 2,5 - 3 hours, so should be normal...
But charging with the usb cable connected to the pc it takes much longer.
Any of you experience the same thing?

Because:
a) That´s how Li-Ion-batteries are charged. To fully charge a Li-Ion-battery you need 3-4h.
b) The power-supply is pretty weak. It is just enough to charge the phone at decent speed, but it is not enough to charge it and intensely use it the same time. In this case much of the power is used by the phone and there is not enough left to do a proper charging. I use a 1,2A power-supply from my old Nokia, and while it won´t speed up charging itself, at least it slows down less when I´m using the phone while charging.

This is not possible. The mighty fruity-phone may tell you it is 100% charged, but certainly it isn´t
You can charge a Li-Ion-battery very fast from 0 to 70-85% you could reach this in 1h. But you have to charge the remaining 15-30% very slowly, otherwise the voltage would raise too much and destroy your battery.
The so called saturation-stage (the charging-stage until 100%) takes longer the faster you charged at the beginning. If you really charged until the saturation-stage in 1h, the saturation-stage will take 2-3h.
If you charge slower, so you reach saturation-stage after 2h, the saturation-stage will only take 1-2h anymore.
In the end it will always take 3-4h to fully charge a Li-Ion-cell, regardless how strong your power-supply is.
Another few notes:
Charging will get slower the fuller the battery already is.
Using the phone with low battery-percentage will lengthen the charging-time quite a bit, a stronger power-supply could help.
Getting the last 20% in a Li-Ion-cell will always be very slow, usage of the phone won´t influence this a lot, and a stronger power-supply can´t help.
It doesn´t matter much, how much charge is left in the battery, to fully charge it it will always take long, as you spend most of the time in the saturation-stage (the higher the left percentage is, the more time you spent in saturation-stage)

The wifi is the killer, try turning it off when charging your phone..
Sent from my GT-I9100 using XDA App
it takes so long to charge because samsung capped the charge current at 650 mA in the battery driver. but other phones like HTC allow charging at the full 1 amp. so that's why its a slow charge, and why its possible to drain the battery even while plugged in to the charger.
Now who wants to ask kernel developers to increase that to .850 or 1 amp and use that lol.
I believe lack of heatsink due to design is the culprit behind decision to cap it at .650.

3 hrs to fully charge, and as i use tunein radio a lot i can tell you on my device with the screen off, wifi on with tunein running, it still seems to take no more than 3 hours maybe 15 mins more at most
I am probably going to order a cheap eBay Li-Ion battery that's 1800mAH and likely has a charge cap closer to 1000mAH. I will know in a week when I finally get my phone and report back if that battery helps. I expect it to heat up while charging and am going to use an external charger.
Two replacement batteries and an external charger go for about $12 USD on eBay btw.
Hi all im about to pick up a n7 and join the club ..
But i'd like to know the first time charging pattern ? If i remember right i have to fully discharge to 0% and then overnight charge ?
Oh and while were at it how long one full charge takes ?
Thanks.

With the new lipo batteries you should AVOID full discharges. Instead, charge the device to 100% before using, discharge to about 5%, turn off, then charge to full while off. That should condition and calibrate the battery effectively.
Also, a charge takes roughly three hours to full for me.
Sent from my Nexus 7 using xda premium
Manufacture doesn't recommend full discharge, they just recommend a full charge before it is completely discharged. What I did was discharged through use to about 30% (out of box it was 55%) then did a full charge.
As far as how long it takes charge, it really does depend on your power. Every house and every location get its power differently really. It also depends if you are using the stock provided charger as you're supposed to, if you're using usb from the computer, whether you are going through a power converter/ u p s or even if you are using a non standard power output to usb. On know my full charge was about 2.5 hrs from the 30 percent to 100 percent, using the stock charger to outlet through uninterruptible power supply which has a built in power converter/balancer because my electricity is crap ( unincorporated area, old house, old wiring ).
Really though you don't have to worry too much about lithium ion batteries. You really don't want to give it a complete discharge, based on the existing evidence. Apparently this causes a relatively significant shock to the actual chemicals the power the battery. However many people say you do not want to completely charge the battery either, but most battery service management programs, the actual firmware that keeps the batteries going, will stop a charge at 99 percent tell you it is 100 percent and no longer charge above that for this specific reason.
if you look around to the community, many people recommend that you fully discharge battery, after using a program like battery calibration https://play.google.com/store/apps/details?id=com.nema.batterycalibration and then charge fully to 100 percent anytime you change ROM so the same could be said with a brand new stock unit. Also let's be honest, your device is going to last 2 maybe 3 years. How much damage can you really do but discharging in a few times in the time? also the batteries aren't all that expensive so even if it does significant damage it is still repairable?

Is it possible to ruin my phone's battery due to overcharging? I charge my phone overnight no matter what percentage it is on, I still charge it I know this is bad, but can this ruin the battery? thanks
You should be able to charge as long as you want w no problems as long as you're doing this in a cool or room-temp environment (rather than say leaving it alone in a car charging at high noon w AC off, windows down & no sun shades on the windshield). If you have your phone charging in hi-temp conditions too long\often your battery swells & you get gradual irreparable damage.

If u make a correct use of your battery it won't get damaged. Extreme overclock, overvolt, etc can ruin your battery, but if u charge it every day because ur battery is empty it's ok, and u won't have any problem.

Normally, when your phone reaches 100 % full battery level, it stops charging and starts discharging. At around 95 % level, it starts charging again. This all takes a toll on the battery, especially over a long period.
If your phone's battery is at or above 50%, leave it alone or turn it off for the night.
I have an external battery pack for use during the day time, just for situations like this.

It'll automatically stop charging itself when it's full, it's impossible to overcharge a modern cell phone battery these days. They are a bit more computerized than the old nicad batteries from back in the day. It's actually healthier to give lithium batteries partial charges at a time instead of draining to zero percent and charging to 100 percent.

How do you know your battery is getting worse if it's always charging?
My personal experience is the less you charge it, the better it will perform. However, when you DO charge it, make sure you are less than 30% battery and charge it to 100% before removing it.
For me it's easy, I basically charge my phone at night when I go to bed and that's it. I easily get through an entire day on this phone, though I admit I usually only have about 2-1/2 hours screen on time (I mostly use my tablet when I am at home)
Do you let your battery drop down to 5% before connecting the charger? Or do you charge every moment you get the chance to keep battery at max?

Nah, that's old news. Modern chargers and devices know when they've hit 100%, so they stop charging at that point and lets the battery dip down to 98-99% before trickle charging up to 100 again, and so on until you unplug. It's completely safe, and you shouldn't trust all those garbage click-bait articles out there. Do not, however, go down to 0% before you recharge it. That can actually damage the cells in your battery, so plug it into the charger before that. If you notice some funky behavior from the battery, like if it's jumping from 30% to 20% in five minutes, or is stuck at 10% for an hour, then it's a good idea to completely drain it to 0% to calibrate the battery since the OS has no idea how much battery is left (so it knows where 0 is again). This will usually happen after flashing a different ROM. Charge it up to 100 again and it should be back to normal.
I personally charge it normally at night, without quick charge, since there's no point in having it quick charge while I'm a sleep for around 8 hours. I'll only quick charge it in the middle of the day, which is almost never, since the battery is freakin' awesome.
Don't worry about the battery too much, but don't reach 0% too often, and you'll be good. By too often, I mean every 3-4 months or so is OK. I base these things from my Sony device which I've had for almost 3 years. The (sealed in) battery was very good out-of-the-box, and it's still very good after nearly three years, so I won't mess with a proven success.
To be safe on the longevity of the battery I use one of these with my wireless charger :
http://www.amazon.com/gp/aw/d/B003P...mer+outlet&dpPl=1&dpID=31OAEbif0lL&ref=plSrch
My battery is usually around 30-40% at the end of the day. I use the regular speed Samsung Charging Pad and set the timer on this outlet for 3 hours when I go to bed. So after 3 hours it stops charging and I don't have to worry about the possibility of damaging the battery (I know about trickle charging, but I think this is better)
Ive read somewhere that the new s7 edge charger doesnt have a power inverter so it keeps charging and wasting power which could damage the charger or possibly device. So know if thats correct.

Whatever you read, either you misunderstood, or the person that typed it was a bumbling idiot. A power inverter converts DC power to AC. Your source/utility power is already AC. A USB charger is merely an AC adapter made for USB. The phone has integrated circuitry that controls when and when not to charge the battery and at what amperage.
I usually let mine get to around 5% everytime. Then charge it back fully to 100%.

Not at all, but just try to not discharge the battery completely to the point where it turns itself off. It won't ruin the battery to the point where you actually notice it there, but it's better if you just turn the phone off if you're able to (unless it's an emergency, of course).

I never used the fast charging, I think that slowly charging a battery is better for the lifetime. Most of the time it is below 10 % before I plug it in and I also want it to be at 100% and ready (green LED) when I unplug it.
my note 3 battery is still superb and I got the phone since 2013
Best way to keep a battery in good health is to charge it to full before you start using it. Also, try and never charge it until it's less than 50%. Charging it overnight is perfectly fine it won't hurt anything but once ina while, at least say once a month let the battery drain all the way, try to turn it back on if it goes off sometimes there is still some juice left and it might start up, once it won't start anymore try and charge it without turning it on to full. I wouldn't do it more than say a couple times a month any more than that is overkill and may do more harm than good. These are the guidelines I use and I have never had battery issues. I currently am waiting for my S7 Edge and on my Nexus 6 I usually get 48+ hours with 4+ hours SoT. I'm just an average user currently.

Hi,
Dash charge can not charge the phone to 100% in 30min
In 30 min you can charge between 40% and 60% depending on what is running on your phone :

Hey,
I don't know definitively but I don't think so. I think battery technology in this respect has moved a long way so you don't have to charge it to full before you first use it, nevermind charging it to full and then over charging for multiple hours.
In fact, phones these days cut off charging and then trickle charge when the battery is full to maintain charge but not try and charge an already full battery thus causing damage.
Bottom line is I would suggest you wait till it gets to 100% before using it but don't need to wait any longer after that.

With modern Lithium ION/POL batteries this is no longer a requirement. In fact the hardware will make it stop from overcharging or it could become a hazard. In fact, Li-ION batteries are best kept between 20% and 80% for longevity. if you plan to store Lithium batteries store them at around 50% charge. so your old phone keep it stored at around 50%. this is also how all laptops and phones are shipped these days. They are shipped with approximately 50% battery charge for any hazard and also for longevity should it have to be stored for a long period of time.
