HI, I'm going to receive my phone this afternoon..just confirmed by DHL Malaysia.
can I know how many hours you guys charged your SGS2 for first time battery charge.
Is it necessary to charge 8 hours for first time use?
Please share your experiences
for my past phone , nexus 1 and nexus s, I charged 8 hours for first time use and 8 hours for my extended batteries as well..
from my understanding, you don't need a extra long first charge for Li-ion batteries, you only need to prevent overcharge/overdischarge which is taken care of by the battery protection circuits.
In other words, turn on and start using it like normal
Just plug it in, charge it. When it's full unplug it.
Took me 1h to charge it up from half. Battery came with half charge.
Thanks mates, I'm charging the phone now
until it's full, I will unplug..
Try to run it through a few full cycles when you first get it though...
do u mean it has to be drain out before next charging?
I think it's a good idea to go from 0 to 100 in the beginning. Not for the battery sake more for the phone to learn what max and min are.

hello
just recieved my HD2 and I've drained my battery to 0%. now I was wondering how long will it take to 100% charge again.. 3 hours? 8 hours?
deiota
ps. Ive done my first 12hours charge already
With the original charger, about 2hrs if you don't use it at the same time.
yes Im using the orginal charger and the hd2 IS power off.
the stuff about charging for hours when you get it and then draining it right down no longer really applies too our batteries.that was for nickle batteries to initialise them and prevent the memory thing. with lithium ion they no longer suffer from battery memory.
ýeah it took about 2 h
2 and half ours starting from zero charge
I never did anything with the battery when i got mine!! Was way to eager to play! Never had any Battery issues.....
I did loosely time it once as i wanted to know what difference a quick charge would make and it seemed like it went up a percent approx every 3 mins... trouble is that doesn't quite equate... it would mean that from 0 - 100% would take 300mins (5hours)! but in reality it probably takes between 2-3hours..
I guess either the battery doesn't charge linearly or the percent display is inaccurate...
I Did a full charge at lunch time since it took me 1day and half till battery to drain completely,
I wonder if I should put it on charger all night long (its 10pm now and I have 80%) or should I let it out of charger...
If your battery needs charge, then charge it. There is NO NEED to completely discharge it and then charge it for sveral hours. In fact, modern li-ion batteries will take damage if _completely_ discharged!
The thing about completely discharging and charging for days is long gone! Batterys have evolved, we dont live in the 1990's anymore
Hi everyone,
How long do you charge your SGT to an ac/dc outlet? And how long does the battery life lasts after its fully charged?
Advance thanks!
For mine, charging time (AC) typically 4 hours (from 5 to 10% left). Usage time is subjective, continuous usage on games or music varies differently. I should said, about 6 hrs plus of continously usage on WIFI & games.
Mine takes a long time to charge, nearly 7-8 hours from 0 to full! Don't know why it's so slow considering I am using the original power cable provided by Samsung!
By far the quickest method to charge the Tab is to first power it down so it is totally switched off.
Now plug in the cable and charge using the supplied power plug.
You will notice a marked difference in time taken to charge fully.

This is an important issue so shall we do a systematic comparison? First,we will charge the battery 100% then we will watch a movie at 100% brightness setting for exactly 1hour. Close the movie and check battery %, report here. Game?
According to my usage scheme (except calling), I manage to get 2 days on my GTab when my NS or MT4 needs to change battery once during a day.
Mine takes about 3 1/2 to 4 hours from about 20-30%. I did a lot of reading on lithium ion batteries and what I found is that the more you fully discharge and charge the worse the battery gets, which is the EXACT OPPOSITE of the old style nickel cad batteries.
In order to prolong the life of your SGT battery (which is crucial since we cant removie it) it is recomended that you top off your charge whenever you can. I work part time and am a full time college student so I always have about 4 hours every morning, wether its at work or at home. So once a day I charge my tab, its usually in the 20%-50% range when I charge it.
Just make sure that you do infact have the time to complete the full charge and remember that the last 10% will take the same amount of time as the first 40% due to the fact that li-ion's do the trickle charge at the end.
I charge it over night, every 2 days
For me the longer charge time usually is from 99% to fully charge. That can take up to an hr.

Yep, sounds good! Also, let's keep the phone radios ON i.e. no airplane mode and the movie should be running from External SD card! Will try it out tonight with 3 Idiots movie which was bundled with my Tab

I watched a full movie. There was a drop of 20%. Normal?

Thanks for pointing out.I was following the old ni-cad battery method! So,basically you and Beards above are contradictory?
Differences between both types of batteries.
http://www.ehow.com/about_5449906_lithium-vs-nickel-cadmium-batteries.html
Basically, no harm discharging the batteries if constantly using. However, it is best to charge it before storage (probably for a period of time) and do a full charge when using.
3-4 hours charging time. one time i got it to last for 3 days (79 hours). i have a screencap but i need 3 more posts to put the links here. my normal usage is 2 days.

Lithium rechargeable battery dies totally (no longer accept charge) if it's left totally discharged for a few months. In addition, it's better to "condition" (totally let it runs out and charge it immediately till it full after about 1-2 months of use) to keep optimized performance.

When I said "power it down" I did not mean to let the Tab run down until it powered off.
What I was saying is to get the quickest charge method it is best to 'switch off' the Tab ('power it down' & 'switch off' = same meaning).
The correct usage for the Tab's battery is when new to first fully charge and then discharge several times. Once you have done this the battery will be optimized.
From now on it is best to keep the battery 'semi-full' and not let it run down completely. I normally let mine run down to around 50% and then recharge to full.
However, after every 30 recharges it is a good idea to 'reprogram' the battery by clearing out any memory loss (I know, I know... they don't suffer memory loss). What you need to do is after every 30 recharges let the battery run completely down and I mean completely until it will switch itself off.
Now with the Tab switched off, recharge. Once the large green battery icon is full leave it in for a further 1hr then disconnect.
If you are not going to use the Tab for a long and lengthy period (heavens knows why though), to optimize the battery never stow away a battery which is in a Full Charge.
Batteries that are not going to be used for a lengthy period should only be charged to around 70% and then left in a cool and dry place.
That was very instructive ,infact I copy pasted it in Color Notes. So, basically, 30 recharges is like once a month, I can put a reminder in the Calender. Thanks and I also pressed the button.

Going to get my Arc on Monday, but I have some concerns about battery life
I see it uses LiPol battery - I searched through multiple formus, but I couldn't find proper advice :
- how to charge/format LiPol battery to get most out of it ?
Should I charge it for 8 hours first 4-5 cycles, or how to format LiPol ?
For Li-Polymor, just charge till full. But make sure to charge it before it falls below 10% - 20%. Charge it often (daily) for the first week. I find that doing so, improve the battery's hold on a charge.
Sony Ericsson's batteries are already charged and ready to be used.. so no need to do 8 hours first, but as darkmax1974 said, keep charging it regularly and don't let it go below 10%
amen. letting it die completely has a negative effect on the longevity
ok, I won't charge it for 12hrs for the first time, like I used to do with new phones
Hello Experts,
I received a new nexus 4 and noticed that it takes around 3.5 to 4 hrs for complete charging from 5% to 100%.... is it normal? my other sony xperia seems to be charge in about 1..5 hr
since i am new to Nexus 4, not sure what is the avg charge time and should i call for RMA? Please let me know what is the avg time for charging.
thx
Ganu
Perfectly normal. You want a nice slow steady charge, especially in a sealed phone. The battery needs to last as long as possible. Fast charging batteries significantly reduces their lifespan. My old Nexus S takes the same amount of time to charge from 5%.. 3-4hrs or so give or take.. I still have the two year old original battery and it holds a charge just as well as it did the day I bought it. Meanwhile my 15 minute charge AA batteries I bought last year lose their charge in a week just sitting on the desk.
Mine is just about the same, but that's under use. If I don't touch the phone, it typically charges to 100% in about an hour.
And if it's through USB.. um.. more like 8 hours to fully charge.
Battery widget reborn (awesome app btw) says my phone usually charges in about 2.5 hours. This is on Qi though not sure about the regular wall charger.
2-2.5 hours for me on usb wall charger and Qi Orb.

I concur.

From 2 hr 45 min (from around 12-15% juice left), my charge time has reached to 3 hr 30 mins now (i.e. from 1% juice left)... 14% juice wouldn't make such a huge difference so don't really know why it increased..

yes, this is one of the reasons i started this thread to understand what everyone is experiencing.... i called up the google customer support and they are ready to send in a RMA as it appears to be a higher side...
so let me know your thoughts guys...should 3.5 hrs charge time considered high and warrant a RMA? share your thoughts.
^ Hmmm.. I doubt if this would mean anything serious or worth RMA-ing. I can but I won't RMA my device because it's been exceptional so far. I am fairly happy with it and wouldn't want to get it replaced with a defected one.
Its perfectly normal especially from around 5% to 100%.. In my experience if you dont let it get below 20% it usually charges faster. I wouldnt RMA it especially if your phone is perfectly fine in other aspects.
I tried with a different charger yesterday and it took similar time. The charger has same voltage input levels.
You charge 3 hours, for only double the lifetime. How pathetic, actually. I didn't thought that the battery life would be that bad. I can hardly make trough 1 day, if I play some games, make some calls, and use a little bit of internet. On the last charge I got 4Hours of screen on time with 15% left.
Gosh, at least it's fun to use it. :/
Just got my OP5 in hand, how long does it need to charge the phone for the very 1st time? As Dash charge can charge the phone to 100% in 30min, do I still need to keep the phone on charge for an extended period of time like b4? Cheers
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 :

Thx. Havent tried it. So for the very first time, for previous phones I let it charge for a few hours b4 actually used them. I should do the same right? As the battery is with the same structure. Cheers

I set mine up then put it on charge, was on 44% and then was at 96 about 35 minutes later

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.
