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.
I recharged my Galaxy Tab 10.1 yesterday from a 15% remaining charge.
I powered it off and used the wall charger. It took almost 6 hours to charge to 100%!
Is this normal or is there something wrong with the battery?
Thanks!
Mine was slow at first too. But now seems to have gotten quicker.

What is the rating on the charger that comes with the unit?
The rating is 5V - 2A
Yep, noticed it took about 3 hrs to go 40% charging. Not sure why there is such a drastic difference from the Xoom which could charge from 10% to full in little over an hour with similar drain to GT.

Can you please quantify what quicker means?
We have a rather large battery in the device, while I agree 6 hours is abit much, it should be quicker at 2 amps.
On the other hand, I sit in on the charger at night before I go to bed. I am definately a heavy user as well, and the battery lasts me all day with atleast 30 to 40% left over by bed time (this includes a 1.5 hour commute each direction using Waze, the GPS, and wifi tethered to my phone, 2 gmail accounts polling every 15 min, web surfing throughout the day, and playing games during my morning and afternoon constitutions .. I know.. too much info)..
So I can live with a longer charge time, at least for now..
I charged my GT Tab completely before using it the first time. Then I drained it down to about 9%. I timed my first full charge from 9% to 100%, it took exactly 6 hours and 4 min. My Xoom charged in half the time. I am hoping it gets better like I have heard from different people.

i believe the xoom's charger is 16watts or more. i can't really remember, but it's got the highest rated charger b/t the xoom, tf, and gt10.1.
I think that's just wishful thinking on their part. How does a battery suddenly learn to charge itself faster. You make it sound like the battery is a muscle you can work out. The thing takes forever to charge but it also has excellent battery life. So as long as you don't find yourself in a hurry to travel without time to charge the battery should last you almost all day.

I charged the device fully before use. Used it down to 10%, plugged it in and charged to full powered off. This took around 6 hours. The second time I charged it from around 14-15% It took about 4 hours. I have charged it twice more since from almost zero, and it's taking about two hours.
Remember the math:
7000 mAh battery
2000 mAh charger
That means from drain to full if the screen is off, about 3-4 hours. If you have the screen or device on and it's doing anything, it's using some of that incoming charge, so will increase to 4, 5, 6 or more hours to fully charge.
Gets even worse if using an aftermarket charger, say a 800 mah or 1000 mah charger like the iPhone or Kindle charger...can then take 10-14 hours to fully charge, hehe.
It's funny how people say it charges quicker after a while, when that's not logical, you just don't notice it as much going from 65% to 100% as you noticed when it went from 15% to 100% the first time, hehe

The xoom charges super fast, like from almost zero to full in around 2 hours. That's about all i miss right now

Smaller battery=shorter charge, a 2 gallon gas tank is quick to charge too, hehe.... kidding.
But seriously, Samsung is bad with their charging. My Samsung Infuse and my Galaxy tab both take forever to charge.

Did I read it correctly that if recharged from almost 0 (e.g. <5%?), it takes only 2 hours to go to 100%? This seems counter intuitive.

i think what happens is that as the battery calibration gets more accurate it finds where to quick charge and where to trickle in the appropriate levels.
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.

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.
Hey there,
I have a question to which I maybe know the answer but anyway... Today I used my phone as I would normally and got 3 hours screen-on time and 5-6 of total time since unplugged (also restarted the device once). So I decided to go into android's default battery screen in settings to see which apps may be causing some drain. While there I decided to open up each individual screen and calculate how much mAh in total has been used during this time. Phone was at 5% when I did this so I was expecting the total mAh sum of everything shown in the stats to be around 2600-2700mAh. To my surprise, the sum was 1084mAh The battery is 2800mAh and it said that the total power usage today was 1084mAh (almost 3 times lesser than the battery capacity!) and the phone was almost dead at 5%. Is it time to buy a new battery? Share your experience please. Btw if I get 3h SOT with 1084mAh in total (according to these stats) then I'd get 7-8h SOT with a brand new battery? Maybe I've forgotten how long the S5 can actually last with a brand new battery or maybe I'm doing it wrong, help with some info please
PS: Charger connects are more than 2200 according to the Phone Info app.
It also says that it needs 1 hour to charge the phone from 1% to 100%. That's not normal right? I forgot what a brand new battery feels like...help. Today got 9h total time and 3h sot.

The sign of a significantly worn battery is when it charges far to fast.
The standard charger provides 2A. The battery is 2.8Ah. Therefore to charge it (2.8/2), it should take about 1 hours 30 minutes if the phone is turned off and if the charger outputs a continuous 2A, which it doesn't.

It still charges for 2-2.5 hours, it only says that it needs 1 hour. It goes up to 85-90% during the first hour and then from that to 100% in the next 1-1.5 hours. Still, looks like I'll just get a new one very soon. At least I can swap it and it's cheap.
Actually, it's time for a new device!
Hi
If you have been using your S5 since 2014 then it's time for a new device not a new battery. A new battery won't make any difference because there's no battery replaces the original one (the one that comes with the device). What you see on the market advertised as genuine Samsung batteries are all fake/replicas with no exception. Samsung does *not* manufacture genuine batteries for sale separately. It's a simple marketing strategy, Samsung wants you to buy a new device every 4 years, these 4 years are the life of the battery (not the device). If Samsung sold the genuine battery separately then few people will buy a new device sooner, and most of them will only replace the battery every 4 years and continue using the device for next 4 years, that's so bad for Samsung.
So my advice is: Hurry up, sell you device sooner before its battery gets worse.
Hope that helps

We both are in the same boat my friend. But remember, once the 4 years pass, every day you keep your device is a nail in its coffin.
