Charging time and use

Hi,
How long does it usually take u guys to recharge ur note from dead or almost?
It took mine. Over 8 hours to charge from 12%.
Also if keep my note on charge but im usimg it for browsing or whatever, my note still dischares.
Is this normal for the note as my htc Desire didnt diacharge while using it while connected to the charger.
Thanks
Neil

Hmmm I've never really timed it but its gotta be around 4hrs for a full charge.
I have been playing Stardom even when charging and it gains battery.
That doesn't sound normal at all.

If u r charging from USB port den its possible. Charging from ac will be a different story
Sent from my GT-N7000 using XDA

Charging by USB is at around 12% per hour, so it does take 8 hours.
Charging by a/c is upwards of 35%/hr.
Some of the apps usage would demand battery usage at 20-25% per hour, so if your battery usage is more than your charging rate then you would be losing battery which is what might have happened when you are using USB charging etc.
If your stats are for a/c charging, then I suspect the charger.

Yeah i charged for 8 hours with ac and also got discharge while using the note and charging.

Are you using the stock charger? What is the battery time you are getting?

Depends on what you are using for, but it still doesn't sound right.
Mine charges from 5% to full in about 3 hours when it's just sitting
on the table and I'm just using it for a phone call every now and then.

charging shouldn't take more than 4 hours when done from an AC outlet. just check if you have original batteries and charger. if not, take it to the shop and get it replaced immediately. 8 hours is just too much.

Im using the stock charger.
Rocket rom / Abyss 4.2 kernel
And battery life was around 20% after around 14 hours then i put it on charge and used it for about an hour but it discharged to 12%.
I am using the device heavily at the moment as ive had it only a few day.

When you are using it heavily while charging it might be normal,
try leaving it alone while charging for one cycle, that'll give you
an indication.
If it's still substantially higher than 3 to 4 hours under these circumstances
you've got a problem, either battery or charger have an issue, or there's an
app sucking battery like hell.

as said, 3-4 hours is normal. Do you have a battery drain issue when in normal use? if yes, then u can use betterbatterystats to check which process is using the juice.
Also, its advisable (in the first cycle after flashing a rom) to charge the phone with switched off. After full charge, take out the battery, wait for 1 min , reinsert & restart. This will help to reset the battery & start afresh.

From 8% to 100% with the charger it took me less than 3 hours.

I only charge by USB on my PC and its never taken close to 8 hrs for a full charge..
The only time charging has taken a very long time for me is when I ran a ICS ROM.

So i did a charge with my usb cable and it tool half the time. Maybw theres a problemwith my ac charger.

[Q] Charging Methods: Which is better?

Which of these two ways is better?
1. Use your phone to 20%~10% of battery and charge it till fully charged.
2.Frequently use and frequently charge(charge from 60% and unplugged at about 80%, then use to 50%~60% and charge again)
Which is better for the battery's life of phones and tablets,1 or 2?

its very obvious option number 1 is good

The only thing you really need to do is break the battery in properly by fully charging/discharging 5 times when you first get it new and don't let it go dead for too long (a week) after that. You should be good.

As above, I just randomly charge my phone whenever I can/need too, and after nearly 2 years still get nearly 6 hours screen on from a charge

Tips on keeping the N7 battery healthy

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.

The battery's are $20 for a new one so as long as it lasts a year I don't mind buying another one. In another question has any one bought a replacement battery yet? And if so does the charge last about the same as stock?

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.

How's your battery life?

My battery life is decent, but the charging time is the slowest I've ever seen on any device I've ever owned. I'm not even kidding. Surely it's just a defect on mine right?

Negative. My charge time was ridiculously slow. To the point that while I was charging in my car, if I was doing things along side it, my battery would actually go down. Plugged into wall, it is slow but charges though. Maybe its just US or a small number?

Waiting to get mine still. Did anyone else notice that on Sprint's website it said the One has a 19 hour battery life?

It seemed a little better this afternoon, but I've basically had the device plugged in since this morning(10am)(got it at 55%, and albeit the majority of the time, it was plugged into the vehicle[which hasn't been very good anyways[[my GS3 also loses battery while on charge if doing anything concerning navigation or streaming]]]) and it literally hit 100% about 20 minutes ago. granted I've been using it like a pack mule. and I'm sure you have too.

Actually I haven't used it at all. Got it at 2 PM, was at 60%. Dropped my mom off at the airport immediately after, came home and it was 50% at 3:20 PM (which is okay because LTE was on by default and it's super patchy here so I turned it off). Plugged it in and showered, 15 minute shower and I come out and it's 50% still (plugged directly into the wall). Went to work at 5, 55% when I got there. Plugged it in to the computer we have at the front desk and over the course of my 5 hour shift it eventually hit 95% before I had to leave at 10 PM. Un-****ing-acceptable.

yeah, I'd say mine is a little better than that. I left the screen off and didn't use it for like 2 hours and it went from 73% to 91.

I bought a 2.1 amp charger and it hoes from 0 to 100 in 4 hours
Sent from my HTCONE

I don't have my One yet so I can't confirm this personally, but I've read in a few different places that the charging rate is a little slow compared to other phones. My guess is that HTC is trying to maximize the lifespan of the battery since it's non-removable. Quicker charging would generate more heat and might cause it to wear it out faster.

Yes this is the case. Check anandtechs review.
Brian speculates just as you do that it is for longevity.

First day I got 15 hours. That was the usual installing apps and watching YouTube videos and showing my phone off to everyone at work. Will probably be awesome once I don't have such heavy usage.

If I'm not mistaken, the phone has a smart battery or a circuit inside the battery that prevents it from drawing too much current. It is pretty much a standard among smartphones these days. Therefore, even though you use the 2 amp charger, you may not charge faster at all.

My Galaxy S3 definitely charges faster with a 2AMP charger than 500 mA charger.
Do not charge from a computers USB port, they are going to be slow as **** without fast charge.
Just use a 1+ amp charger. Pretty simple people.

Don't put excessive work load on the device while charging in the car either

I've found thats too much for most phones. It all depends on the charger(most car adapters are crappy), I'd assume. I've had the same with Evo, Optimus, GS2, and GS3. If anything is running alongside gps/navi, it destroys the battery

will the battery be ruined if phone is constantly plugged in?

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 )
