Is it me or does our phones charge super fast?
I drained it to 0% (let the phone die by itself while watching youtube)
Then I plugged it in at 8:05AM this morning.
At 9:05AM it was at 45%.
Pretty impressive.
(Once charged to 100%, should I wipe the battery stats and drain down to 0% again? This is how you would calibrate it correct?)

If you are getting incorrect stats then yes, clear the battery stats. The best way to calibrate is to drain, refill & repeat. Along the way when the battery is 100%, turn it off and charge it till it says its full again. Do this a few times when it's unplugged and you will see better life.
Speaking of fast charge.
I had 17% left at around 12:30pm today. Plugged it in while I went to lunch. Now at 2:50pm, just got notified that it's fully charged. Not bad at all.
Also, I had drained my battery when I received my phone.
How is that even possible!!!!!!!!!
It takes me 3.5 hours to charge it full!!!!!
Damn!!
I have two lines and this is my second SGSII aside to the one I already have...
I got this phone just yesterday and last night was my first full drain....today was my first full charge.
Shouldn't I go into recovery and wipe the batt stats?

I noticed today that the output from the charger for the SGS2 is 5V 1A and all other usb chargers ive gotten recently have an output thats closer to an actual usb port (4.5-5V 500mA) so that might have something to do with it.
My test pool on this hypothesis is quite small though so id be curious if anyone else can corroborate
I notice my battery charges much faster on an official samsung charger. Anything below 1V charges super slow. I want to try a rapid 2V charger but worried it may ruin my battery.. but on the other hand, AFAIK, some samsung car chargers charge @ 2v. They're called "rapid chargers" This is one of those times where you think AH any generic charger would do. I used to be in that camp. But I really found that the Samsung chargers are quickest. Also, they seem less likely to damage the micro usb port due to repeated use due to the fact that the Samsung cables tend to be thin and light weight as opposed to thick and bulky like some eBay cables. The thick and bulky ones feel like they'll give you enough leverage/weight if grabbed the wrong way and tear your micro usb port right off.
In the end, I love the Samsung chargers.

There are lots of myths regarding lithium batteries.. some say you are not supposed to overcharge it (charge it only when it's running out)
Some say it doesn't matter since lithium can be recharged as much as you want and it won't deteroriate the battery's life.
Which one? Can I recharge my Touch Pro 2 every night before I go to bed and leave it until morning? or should I do it when it's running out to preserve the battery's life?
You should keep the device on A/C power as much as possible. So, it's fine to charge daily overnight. Every once in a while, you should let the battery run all the way out before recharging. What this will do is keep your battery meter reading accurate. If you don't do this, eventually, your device will "think" it has more juice than it actually does.
Check this:
http://www.batteryuniversity.com/parttwo-34.htm
Ah thanks
So to cut the story short, recharge it as much as you can and prevent the battery ever from being run out
Nahhh, not fully true. Somewhere else on the site of batteryuniversity it sais that completely discharging the battery will reset it's memmory. This is usefull after a lot of charges and discharges (in the beginning, I think they already did this (you may hope).
(the memmory helps the battery know where his power is storaged and how much power the battery has left. But doing this frequent speeds up the battery 's lenght of life
In my experience
Enjoy your device and charge battery when needed/desired
Use it normal
Batteries have a duration of 3-4 years aprox, no matter if you charge it every night or leave it till it´s empty...
When battery fails you buy another one and so on
Just my opinion,
My experience with the battery life on my touch pro 2 is that I will keep the phone usually docked in my cradle on my desk when working so it's always on charge. When I use my battery I wait till it's about 40-30% drained and will stick it on the cradle again.
When I'm in my bed ready to sleep, I use the normal charger and leave it on charge over night.
Still experimenting though.

Hmm, first of all Li-ion batteries have NO MEMORY unlike NiCd batteries. You probably refer to resetting the reading gauge - which is related to device's capability of getting accurate reading rather than battery itself. It is recommended to let the device die once a month and give it a full charge to "recalibrate" phone's battery meter (not the battery).
But you should avoid hitting 100% battery mark as well as going bellow 30% as much as possible.
from my experience as a phone shop owner and owner of many many phones i always advise my customers and friends as follows:
1st charge 10-12 hrs. allow battery to fully discharge
2nd charge at least 8 hrs
after 2nd charge you can charge and use as you want. the initial 2 charges kick start everything and starts your battery cycle on good stead
never had any complaints!

The battery should be as cold as possible when charged. So if you are using the phone the battery power drains and is charged at the same time. Therefore it gets warmer than without.
Best for the battery is to be charged when the device is switched off completely.
I wouldn't consider that much of a problem, because you have bought the device to use it and not to live in fear that you treat the battery right
when plugged into USB and playing a game on my TP2 I got the message the device is using too much power, and it drained the battery even though recharging via USB. No problems when using AC adapter though.
Used my XDA Orbit 2 for 2 years now, and mostly charged at free will. Battery is still fine, so no special charging rules for me...
I noticed though, that charging over USB takes quite some time while charging over AC cable is done within an hour or so. When looking at my AC it has 5 Watts of output power, while the USB only has 2.5. That would explain your issue with the battery running out even when having the USB cable plugged in.

So I just ordered this charger and it charged my phone from 4% to %100 percent in exactly 3 hours!
http://www.amazon.com/gp/product/B0051ZJA64/ref=oh_o00_s00_i00_details
Wow, what a great improvement over stock which takes 6+ hours. This makes me believe, that even though the stock output is rated at 1000ma and this charger's output is only rated 700ma that this charges works correctly!
If you have a 1800mah battery and you charge it at a rate of .7A, it should take it exactly 2.57 hours to charge, (1800/700). With stock it should take less, because 1800/1000 = 1.8 hours, but it takes 6+ hours to fully charge! Something is f'ed up with the stock charger or phone's software...
Yeah. About that. I just got my E4GT yesterday and noticed it does charge extra slow compared to my O.G. Epic.
My wife stayed with hers, maybe I will try charging my phone on hers. I wonder if that would make a difference...

I use the Palm charger from my TouchPad. Will go from dead to fully charged in about an hour and a half.
What's you TouchPad charger's output in mah? I think I might have to splice into a spare USB cable and check how much current is actually used by phone when on stock charger...pretty sure it is nowhere close to 1000mah.
2000mah is the output from the TP charger.
According to BatteryMonitorWidget, it estimates avg mA charging at 270mA using the stock charger that came with this particular phone.
I have my original charger from my Evo 4g and have noticed that it charges my phone a lot faster then the stock one that came with the phone. :-( weird

Yeah, at 2000mah it should charge in less than one hour...I would say your actual charge current to be around 1200mah...
i would be careful with these chargers.
i have dealt with a lot of Li-Po's in the past and there was a formula to how fast you should charge them.
i imagine it is the same deal with Li-On.
charging outside such formula could kill the life of your battery or worse.
Seems like i must have gotten lucky as a ton of people are having problems with their phone or chargers.
I just charged my battery from 0 to 100% off the stock charger in 2 and a half hours and i also havent gotten any of the dodgy input problems using the phone while charging.
I went back and took a longer look at the battery history when charging. When starting the charge at 65% it starts off around 828mA, then 540mA, then 360mA, so it looks like (as expected) the phone knows how much current to pull to charge the battery safely and it adjusts based on how full the battery is. Not saying it does this for the charger included with your phone, but that is the behavior for the charger included with this phone.
These are all estimates provided by Battery Monitor Widget because there is no real-time mA current meter in this phone (according to the author)
Ordered one of these. Stock charger takes a lifetime to charge the phone.
My GF got Nexus S 4G and it's stock charger also takes 6+ hours to charge, so there's something wrong with the chargers I guess...
The pins on this charger must me different than the stock charger. Just because the stock charger is rated up to 1Ah doesn't meant the phone or batteries circuitry allows that much output. The resistance and length of the USB pins on the cable are what determines the output of the charger. Simply using a different USB cable with the stock charger will get you faster charge times.
Using a 2Ah charger will get you nowhere, the circuitry doesn't allow that strong of a current. Just a bit of an FYI. Save your money and save your phone, use a different USB cable.
Also, how is the charge time holding up? I doubt you're getting a saturated charge with that charger.

Ive dealt with 1,2, and 3 cell lipos ranging from 150mah to 5000mah, and every one of them either say to be (or ive been told its recommended to do so) charged at 1C. so a 500mah battery should be charged at .5A, 1000mah at 1A, 5000mah at 5A, etc...
my lipo charger displays a bunch of info as the battery charges and it definitely drops the current as the battery gets closer to being fully charged. if its the same with li-on then I would imagine that .18A should be the most you would charge this battery, but Id rather it take a long time because unless things have changed recently, doesnt the slower you charge the battery prolong its life cycle as well as extend how long it lasts each charge? I only charge mine at night when I am sleeping so who cares if it takes longer than an hour. if I get into an emergency situation I have the cig lighter charger and in the worst case I even have one of those crank flashlights I can use to charge the phone in the event my car battery shorted out or something...
Flattened my Xoom earlier, as I do everynow and again to full cycle the battery.
Came back to it a bit later and it had charged up to 40 odd %
Used it for a while then it suddenly said the battery was flat and switched off..
Anyone else had this, am I looking at a dead battery or should I just leave it swtiched off and on charge overnight?

It shouldn't be, lithium ion batteries don't have as intense a memory problem as the old nicad batteries...maybe just wipe the batteries stats in clockwork for good measure and take it from there. Sorry I forgot to mention that this would assume you are rooted. All my Android devices have weird jumps like that, but not usually that extreme.
cool, I'll clear the battery stats and see what it says in the morning.
Clear the stats in the morning after the full night charge not before..

Good job I checked here before I went to sleep eh
Lithium batteries do not like to go all the way down to dead (so low the device won't even start). They wear alot if you do. There is no reason to cykle them after the first time charge as there is no memory effect on them.
I had a laptop battery partially charged installed in my laptop and did't use it for two weeks. The battery went compleatly dead and when I charged it I only got like 20% into it before it said full. I had to buy a new battery.
So don't leave your XOOM with 1% battery for a long time. If you are not gonna use it for a prolonged time charge it up to about 75% before leaving it.
SEALen is correct, Lithium batteries should not be fully discharged it significantly shortens their lifespan, there is also no memory effect, the only battery type that ever did have one is NiCad.
The best way to keep a lithium battery healthy is to charge little and often, keep it topped up.

+ 1 to your arguments however if he is doing a calibration, i let it get to 1% before charging it again, i dont let it die i watch battery widget pro and watch the mA.. This will not fix a battery but give better indication of its lifespan

Just wondered how most people are charging there One X? Personally I always turn it off and allow it to charge until the light goes green. I've never charged it when it's still been turned on.
I've never switched off any of my android phone's whilst charging. What happens if you get a call? I also try to alternate between charging on my pc and the wall charger.

Yeah fair statement, I had thought about that. I wasn't sure if it was bad to say plug the phone in at 11pm until 7am (8 hours) charging whilst it being turned on? I assumed if it was going to be plugged in say for that long that you should turn it off.
I just plug it in - went to bed on 80% last night but fair enough I'd hardly used the phone all day (standby battery life is incredible)

So you stuck it on charge just to boost that extra 20% yeah? How come you didn't just leave it until it was low?
Should of asked if people would partially charge it or if they always ensure its fully charged.. Can't amend the poll now though.
I was thinking about trying that - might do that tonight and see how it lasts...
I plug it in to a usb cable
i charge my hox every night on the wall charger while turned on. even if it has 80% left. i am to afraid that my battery level goes under 20% (i heard that falling under that level can damage batteries).

Where did you hear that? Mines dropped to 14% before and I then turned it off and charged it and the battery still seems fine. Wasn't aware you could damage the battery if it got too low...
I killed my battery first 2 charges - never have in the past but thought I would this time
I have always charged with the phone on, all my phones since way back having an analogue Nokia mobile and never had any battery issues. Only time I have ever switched my phones off is if I was getting on a plane or the battery got really low and didn't want it to go completely flat.
Just plug it in whenever. Modern li-poly batteries doesn't have memory and charge cycle life is based on full charges.
Part charges actually increase life due to low % cycling

Agreed.
One thing to note is that you should never let it completely drain the battery, the phone will switch itself off once the battery reaches critical level then it needs a charge. I'd recommend charging it when it reaches 5-15%.
Also I'd never leave it charging over night it interrupts the cycle, if I have to charge it over night I set an alarm to go of after a few hours and unplug it.
i have 3 or 4 charges from different makes-and only htc charges the quickest. the worst is usb cable and car charger. but due to usage i need to charge twice a day

You are 100% right most modern phone battery’s don’t have memory any more so no need to worry about it, and no need to do full discharge and recharge cycles to maintain battery health, and if they do they normally tell you in warning labels or in instruction manuals, for example I recently bought a new shaver and it tells you to do a full discharge and then leave it on charge for at least 12 hours every 3 months to maintain battery life.

batteries have safety features built in so don't worry. What for you looks like 0-1% left - what android is showing you, might be actually 10-20% as seen internally by the battery.
Also, I have completely discharged my phone once, I simply left it at 1% and waited until it shut off. Then I charged to 100%. From then on, I charge whenever I want, phone is always ON.

ok, so i just got the Galaxy Tab S, and a friend of mine, who has one, told me i need to let it drain before the first full charge.
idiot that i am i just ran with it without checking.
so now pretty much wherever i look i see ppl saying u should give a full charge first b4 any use.
hell it even says so in the quick start guide, but i was too excited to check
anyway i drained it and started a full recharge, but now i'm worried this back-asswards treatment might have done something to the battery.
should i be worried?
any possible effects on battery capacity, life, or charge speed?
BTW, i'm charging right now and the charge speed is INCREDIBLY slow (like only 50% OVERNIGHT!)
not using the official charger so i'm being optimistic and blaming that, but it's 5V 2A compared to the original's 5.3V 2A, which seems to me like it shouldn't be a problem,
but what do i know ?
TL;DR
went retard and drained my brand new Galaxy Tab S instead of giving a full first recharge, now worried about adverse effects to battery capacity, life, or charge speed
thanks !
A full charge is around 4+hrs for the 8.5" and 5+hrs for the 10.5" , only 50% in 7-8 hours is slow, the Tab S has detected that you are not using the Samsung charger and is slow charging your tablet.
The free app below will show you how fast you Tab S is charging, you have to keep pressing refresh on the free version, look at the average ma, not the maximum one as it only shows the maximum charge rate of you tablet.
My 10.5" charges at between 1500-1600mah, up to 80% after that the ma will keep reducing till the tablet hits 100% and stop charging.
https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free&hl=en
EDIT: discharging to 0% every 6 months or so will help calibrate the battery gauge, but a few Tab S owners whose tablets battery accidentally went below 0% which can cause the battery low-voltage protection to kick in and disconnect the battery, which means you have to send it back to Samsung or an tablet/phone repair shop who can reset the battery protection.
