Despite all the tricks to help preserve battery, I still find the performance of y standard 930 mAh battery very bad. Is there an extended (reliabl) battery for rhis phone and where can I get it?
Just gonna drop my experience in. It seems the battery lasts for about a day and a half. Which can be seen as over three days (depends what time you charge it on the first day) instead of using the normal homescreen, download helix launcher from the market, it helps alot

One day and a half compared to my brothers Samsung's week is really a disgrace.
I already have another home screen, just got to like it, so not changing it at the moment.
I have contacted Seidio as they make extended batterys for other phones. Would not hurt if oter people did that too, so please, those who care about this problem, contact them and ask them.
I bought on e-bay a 1450mAh battery made by Jin Dian. A drastic improvement.
Didi anybody else try this? I got it but I'm not convinced it's better.
Seeing you all really hungry for power, it's just feel right to warn you guys. Never ever use cheap small portable charger that you spot either on a shop or ebay no matter how desperate you are. If you use it, best scenario, it only ruin your battery, or in the worse (like me) it ruin the phone. Both case has the same end result, the battery discharging way to quickly even when Idle.
How did it ruin your phone?
I would like to know. thanks
As I'm a long distance cyclist, I already own the Biologic ReeCharge. Anything that can be charged by usb can also be charged by that tool. I can use both my bicycle dynomo hub and the electricity network at home to charge the ReeCharge. Witch then is able to charge my phone. It's a kind of extra battery. Never have had any problems with that and I'm always glad on a cycle trip that I can keep my gadgets (most important gps) charged

Well, I don't know the technical details but it fried my batteries (that's right, more than one) before I realized it was the portable charger that caused and even after stop using it, it's still recurring (therefore, the phone is at fault) After asking my friend who used the same type charger once. They all said that it ruined their phones and told me if I want to have a portable charger, go for the lithium one that sony Ericsson's is selling.
hi,
i'm using varta charger type 57048:
http://www.amazon.de/Varta-Professi...=sr_1_3?ie=UTF8&s=ce-de&qid=1291062768&sr=8-3
and i don't want to miss it on longer journeys. the usb-out function i would say is nearly as fast as the normal charger. one akku pack is enough for about 2 charges. if you are on a journey and not able to charge the akkus you can buy normal batteries. they give about 1 charge.
i have experiences with other chargers and phones and i would say this thing works really good because the usb-port of the charger turns off when batteries haven't enough voltage. this prevents your x10 battery from damage because wrong charging.

My x10a mini pro came with 970 mAh battery, not 930. Battery life is about a day and 1/2. I use USB car charger in the car on needed basis only. Hopefully USB car charger doesn't fry the battery.
Hi Guys,
I’ve no experience of using Power Banks ever so here is my queries and doubts. As far as I know as much the mAh the power bank have, it can hold more current and charges other device for long. Is that correct?
# My primary question is it safe to Power Bank to Charge your phone?
# Also is it safe to use a higher mAh external charger like 10400mAh? The stock charger shows 2amp output.
# Could it damage the battery for longer use? (I love my phone very much and I scare to use non branded after market stuffs)
I found this product Xiaomi Brand Power Bank 10400MAH (please google it and see the description) and it has 10400 mAh, and looks like best for Note 3’s giant 3200mAh battery. So is it safe to go for this product?
My purpose of using this, like once in every two full charge. Please advice, thanks
a "power bank" is nothing more than an external battery. Almost every cellphone manufacturer makes one. The bigger the mAh, the more power it holds and the more devices it can charge..
In my experience, it is safe to use them. I have a few that i have used over the years. I would recommend getting one where the mAh is more than the battery in the device you want to charge.
I have a Motorola external battery that is rated at 4000 mAh. I use it for my Note 3, but it will not change the Note 3 t0 100% if it's starting from 0%. Even thought the Note 3's battery is 3200 mAh. But other external batteries I have used have been able to. I assume it's because their mAh is higher (9000 mAh and 10400mAh).
As for the specific one you are looking to get, all I can tell you to do is read the reviews, and if possible, search the reviews for any references to Note 3.

Thanks for your feedback. Yes I’m looking for reviews specificly for Note 3. Just two question, any external power bank charger charging rate/speed is similar to the adapter (If its mAh is higher than the device battery)? Or its more faster or slower to charge full?
The one I’m looking for its specification shows Output voltage: DC 5.1V and Output current: 2.1A (TYP) which is slightly higher than the OE power adapter. So is that safe? However it says it can automatically adjust the output power according to be charging devices. Don’t know how far its true.
My only concern is it shouldn’t reduce the stock OE battery life.
I use this one and have no issues using it to charge the Note 3 http://www.amazon.com/gp/product/B00EHEEFWY/
Unless it's big enough to fully charge it twice I don't see the point in getting one.
http://www.amazon.co.uk/Xiaomi-Power-10400mAh-batteries-Sensation-Silver/dp/B00IL7VD1Y
Is this the powerbank you are planning to get one? Looks good.
Yeah honestly anything with a 2 amp port and 10000 MAh will charge your note 2 twice I would say maybe a 11000 MAh charger just to make sure since I believe there is a loss of power during the transfer which causes the external battery brick to discharge faster and causes there to be a significant loss of charging capacity at least in my experiences
I use this one. http://www.amazon.com/gp/aw/d/B003ZBZ64Q/ref=mp_s_a_1_1?qid=1400257970&sr=8-1
It will definitely charge your note 3 two times and it has a 2 amp port and a 1 amp port. Under $40.

I have never had one reduce the battery life of an OEM battery for any phone I have used. I have heard however, that the capacity drops for the external battery over the course of time. The first one i had (Motorola P793) had this issue, but I opened it up and replaced it with a larger battery (THIS IS NOT RECOMMENDED!). It lasted for another 2 years and before I opened it up I had it for about 18 months.
As for the Voltage, it needs to meet or exceed the voltage for the OEM charger. Also, make sure the miliAmp (mA) or Amp (A) rating meets or exceeds the OEM charger. That way you will get a similar charging speed. Cannot say it will be exactly as fast, but it will come close.
Why use power bank with galaly note 3 when it has removable battery? Spare battery would be much more convinient. No wires, smaller size and you will not have to wait till it charges the phone.

Yes this is the one I’ve selected, it has 10400MAH so I think it should charge the Note 3’s 3200mAh giant battery twice. Also it has kinds Apple looks and I will get it here at around $28USD
But actually I was looking for something which I can carry with the phone attach or I can still use the phone when it charging the phone even if can charge single time. That would be great user friendly. I really liked this one (attached image) but it has only 2200mAh which cant do a full charge sadly.
I just dislike when I’ve to leave the phone away for two+ hours for charge and I missed calls and messages.

Yes that was my most preferred way, I love to stick with OE equipment. But the issues are:
I use this leather flip cover and I love it too, I have to remove this and then again the stock back cover, also power off the phone. Those will be long process to replace the battery, not a convenient way for me.
I'm using the 15600mAh A-Solar XSTORM Power bank. I use it to charge my Note 3 and my NotePro. http://www.xtorm.eu/EN/xtorm-power-banks/xtorm-power-bank-15600-646.html
So far I've been using it intensively for 5 months and it hasn't started degrading yet.
You appear to be mistaking mAh for Ampere charging rate. The Note 3 battery is 3200mAh, it charges at 2A. Basically, it's an 80 litre gasoline tank and you can fill it at 0.5 liter per second.
- Yes, you can use it safely. There's no damage risk.
- Pick one with a 5V 2A port, because anything lower than that is not powerful enough to charge the Note 3.
- No, it can't damage your battery. The phone doesn't draw more power than it can handle.
Anything below 10.000mAh is not worth the money, in my opinion.
I also have an additional battery. Which is wonderful, but not very useful when you're in the middle of something. Changing the battery during a call is not convenient.
I was using the Rav Power 10400mah power bank since last year and it helps when I am out on the road or on a plane (13 hour flights.. yeah it helps!) Thats 2 to almost 3 charges for my note 3.
I gave it to my wife so she can use it, I got the Zerolemon for my note 3 now so I dont need it as much
The reason why a power bank makes sense, at least to me, is that it's not device specific. I'd rather buy a power bank and share it with my iPad or my Nexus or whatever phone my friend may have, rather than having to randomly carry around a spare battery that can only help me (and it's kind of hard to justify carrying around a battery when I could carry around something that could charge multiple devices simultaneous). It is also one hell of an inconvenience to have to find a safe place to take my case/cover off and swap out the batteries. To each his own, right?

lol! The zerolemon 18000 mah charges my note 3 atleast 3 times. I bought it a month ago. Charged the external battery all the way once and probably charged my phone it 3-4 times by now and i still see the portable pack to have 1 bar out of 4 left on the charge meter . This thing is a beast to the max

If you are into good case covers for the phone, then you know it sucks to have to replace batteries. If you're gonna be out for the whole day and you have no access to outlets and still need to use you phone a lot, then you'll need a power bank.
Thanks for all your feedback. Yes definitely higher mAh power source should charge multiple times. Like gutlessmerc said, if one can do full charge 3 times then definitely that is worthful.
Actually while traveling except Flight I don’t have power issues, I mostly use my car for traveling and use car charger. But the great thing would be if I could carry the power bank in my pocket when its doing its job. That would be great for me. So I don’t have to leave the phone for charging. So beside the mAh I’m also looking for a slim one. Not a bulky stuff.
I would like to know what do you think of Samsung Wireless charging pad!
Do you use it,if yes how much and what is your opinion for it?
I use it every day & I love it. Lights up blue when charging and turns green when fully charged.
Sent from my SPH-L720 using Tapatalk
I use it every night (with night clock on) and the phone is always 100% in the morning. A couple of times I've topped up during the day using the wall charger as it's a bit quicker than wireless, but I love the ease of wireless. It saves me trying to find the cable in the dark when my wife is already asleep!

Negative experience! Charging very slow in comparison to normal charging - i really regret buying it!
Just ordered one - albeit not the official Samsung thing.
Looking forward to use it on my desk/to keep it up and occasionally even for my N7? We'll see.

It suppose to be slow. Ideal of leaving overnight or leaving it when you not using it.
I didn't buy one because I have a SGP wireless charger which is a Tylt Vu OEM. I prefer a vertical standing wireless charger so that I can have a look at notifications or incoming calls easily without having to lift up the phone everytime.
I didn't get one either coz I got other chargers. Using a Frunda one (Chinese OEM) that works really well and fast for work.
And at home, I'm using the WCD-100 for LG G3. Speed is good too, However, I have to keep my phone upside down due to misalignment of the coils. Not a big issue, as I have programmed my device to rotate 180 deg when on the LG cradle.
My quick charger still in wraps..
I had a previous model of this unit which was at the old "slow" charge rate and was so pleased to get the new and improved version. They even fixed the few issues I had with the older version. This model has the charging cable in back instead of sticking out the side, the LED indication light is much dimmer, although larger, which makes it easy to see where to place the phone in a dark room and not act like a flashlight while trying to sleep.
The display angle is acceptable, it works well through a case, although I haven't tried a Defender case yet and the fit is more secure than even the Samsung charger..
The unit uses a microUSB connector and a 2.1A adapter, not included.

I have a fake wireless samsung charger but my phones gets a bit hotter then when i use my cable to charge so i stopt using my wireless charger. How hot does your phone get because i doubt that there is a fan inside your charger so hope you can awnser me.
I just wanted to chime in since I own this device too.
I've tested out on several devices even for those without supporting native wireless charging (one plus 3, iphone 5s and such) and surprisingly, this thing can charge other devices really well.
I own many wireless charging devices but never had one like this on a stand. this thing can charge my phones while streaming videos.
I'm getting ready to jump over to S8 or S8+ when available and I think this charger is a good place to get ready since it supports fast wireless charging as well.
this charges iphone with a wireless charging receiver. it charged iphone about 75% in 60 min. i know it's a small battery but it goes as fast as regular charging block that comes with.
and it can charge on both horizontal and vertical. good way to stream while charging your device (but slowly charges)
and One plus 3 for work

it is quite cool, no excessive heating or anything. it is warm to touch but nothing like you can't keep your fingers on it. battery temperature stays relatively cool while charging. it stays around 35C according to 3C battery monitor widget.

s7 is great but little too small, I could have gotten s7 edge but I didn't have to pay for s7, so I went with it.
but you're right.. s7 is beautiful comparing to s8 leak photos and videos. but I'm curious to see how that infinite display thing goes. probably a marketing gimmick.

Yea, the reason i went for the s7 was because it had a homebutton and no curved screen but now that the S7 has curved on all screen and no homebutton i really think ill change phone brand again because i really hate onscreen buttons on my phone before the s7 which was a z5 xperia. But dont you have nougat installed? I think the battery life got so much better with that update that i might stay with the s7 for a extra year and hope the homebutton will return on the s8 or maybe under the screen but it should always be on the fron and not on the back.
But to get back at the subject, i saw that you own one of these chargers also right? Does the phone get hot while charging?
I replied with your quote above on my first comment. charger itself gets warm but not hot to touch. My s7 battery temperature doesn't go above 35°C during the charge. I'll post another screenahot via battery monitoring tool when I get home to charge.
I think they positioned their coils pretty much flushed to our phones in either position for optimal charging.
I know the flat puck chargers don't have indicator of correct position so if slight off to center get your phone hot. Don't really have to worry for this one since it has a tray to put down your phone.
I'm getting stand/tilt wireless chargers from now on because just by not worrying about getting right in the center is totally worth it.

Thanks, ordered one $15.99. Awesome price at lightning deal!!
nice wireless charger!!!
After reading this thread I have now got this great charger. It charges with a thick cover on the phone.
Bought it. Design cool, led is not too bright in dark, it's easy to use both in horizontal and vertical stand.
But, I could not get it to charge it fast, it's always showing standard charging (ampere says 500mA on average, so a standard usb current). I tried two chargers, one is Samsung rated at 1.8A and the other is 2A. I use slim Ringke case and tried charging with and without it on.
OK, I tried another charger, the official one for S7, and this one DOES support Fast Wireless Charging. The reason is that the charger support Fast Adaptive Charging. So be vary, having just a 2.0A charger doesn't guarantee fast charging, it needs to have FAC support.
This S8 is going to be my first sealed battery phone. I'm going to miss those days of being able to carry a spare battery and get back up 100% in 30 seconds. I'm wondering if I should get a battery case or an external battery bank?
Which one do you use and why do you prefer it? Is there anything that you don't like about it?
I've been reading that it's best to charge the sealed battery when it drops to 40% and then stop charging when it reaches 75-80%:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
I think it'd be easier to do this with a battery case that has an on/off button.
just avoid discharging to 0% and when ever you can don't charge to 100%. I heard somewhere that s8 battery has better properties that last generation samsung phones and it wear out waaaay slower.
External Battery Bank.
Coz, I don't want my phone to be as thick as a brick. When the bettery is going to run out, I prefer to use the cable to connect to a power bank.
In addition , the power bank mostly have much more juice than a battery case.
I think a battery case is more convenient. I have both and I like not having to carry the phone in one pocket and the cord and bank in the other. However, having a bank allows you to charge multiples devices and last longer since it isn't made for a specific device. The bank would be more useful and the case more convenient.

hey guys we are in the 2017 era, do you really think that those batteries has some problems in being discharged to 0% and being recharged at 100%?
you will sell this phone before the battery die, this is sure
in any case I prefer the power bank way, just bought some of them.

I think a battery case would be better because you can slap it on charge up then take it off after. With a bank you have to plug in the phone and have the cord hanging around while the phone charges. Check out my boy Flossy's video:

I usually carry an external battery pack in my backpack. Though I hardly use it. If I'm going on a weekend camping trip with my friends, I slap on a battery case.

I'm surprised there were more people with "battery tips" than those willing to reaffirm this statement. As long as you're using reliable chargers and/or charging cases and not regularly in 110+ degree weather, you really don't need to overthink things when it comes to insuring the longevity of the Li-Ion batteries Samsung uses.
As for the base question, I agree with...everybody, and say both.
The S8 is not a small phone to begin with. Without a case it barely fits in the back pocket of most of my jeans at least a bit, and creates a clear rectangular outline in all but my loosest of jeans that just looks...awkward. I don't like big phones for every day use as much as most people seem to, but if I'm dressed semi-nicely and going out for the evening I'm fine with the way it looks and feels in my back pocket.
There is NO battery case that exists where that would still be true, I mean, as others have said, the phone becomes a brick. For regular use outside the house, battery cases just look and feel awkward. I've now owned three, including the insanely overpriced Mophie option sold at Best Buy (it was a gift, don't waste the money) and when doing work around the house they're great for heavy use through a full day, whereas I usually have to plug it in fairly early into the evening when running on the internal battery alone.
For every day use, outside the house, I always carry a messenger bag with a QC 2.0 compatible battery pack. Considering the fact that most battery cases are bulky enough to warrant carrying them in a bag, it just makes more sense to me to carry a 18650 cell based battery pack with a far greater capacity (even on the low end) than any case is going to have, and when in use, or if I want to put my bag down for a while, I can just unplug and use my semi-normal sized phone, or carry it less awkwardly in my pocket for a while.
Especially with QC 2.0 being so...quick, I'd say a battery pack is far preferable for most people in almost every case, but battery cases do have their place here and there. If I need something really compact I personally go with the Anker PowerCore Speed 10000 (36Wh), but I usually end up carrying one RavPower or Anker's larger packs that can use QuickCharge to charge the S8 as well as the battery pack itself. Its not as notable if you're only draining the battery pack every few days and charging it overnight, but for my purposes, often on the road, camping, and hiking, being able to have a 72-80Wh pack charged in less than half the time has been a huge convenience.
I'm using this one.....
Plus 1 for power bank
Battery pack
I'm using a battery pack, usually when I'm out long enough to empty the battery I bring my backpack which has a usb port on it
