How long does it take to fully charge your Moto 360 2nd edition?
I bought mine last year when I was on a student exchange in USA and as far as I remember, it charged pretty quickly, I'd guess one hour from zero to 100%. Unfortunately, the watch stopped working a week before my departure, so I sent it to Motorola for repair and had my friend redirect the new device to Europe. The new watch arrived yesterday and it seems to me that it's suddenly charging really slowly. I need 2 hours to fully charge the watch which is annoying.
So to repeat my question: how fast is the charging? Are those 2 hours a normal expected time and I just got that mixed up in my head for some reason?
The charges are in general not compatible between USA and Europe. The sockets are different and also the voltage is not the same. As you know, the Moto 360 charger consists of a cradle and a micro usb adapter. I replaced the American adapter with a micro usb charger I use for my phone. Is it possible that the American cradle and the European charger are not playing well together?

I'm in the UK and use the provided Motorola adapter for charging my 42mm. It takes about 2 hours to charge from 0% - the first 70% goes pretty quickly, but it seems to slow down significantly for the last bit. For example, I just started charging from 60% about an hour ago, and it's now saying it's at 90% with 13 minutes remaining until full. Hope this helps!
Huh, interesting. I would have sworn that I was able to charge my Moto 360 way faster.
The point is that I was used to sleeping with the watch on my wrist (alarm!) so I had to charge it during the day. Usually, dropping it on the charger for couple of minutes several times a day (i. e. while I was taking a shower) was enough. Now, when I come home with 30-40% of battery, I have to leave it on the charger for at least an hour and that gets annoying.
I'm thinking about buying a faster micro usb charger (for example those chargers packed with tablets like iPad are faster than the normal ones). Do you think it might help? Or is the speed limited by the cradle itself?

I think the speed is limited by the cradle. Even if it's not, faster charging will generate more heat which runs the risk of damaging the watch. There are quite a few examples around the internet of people who found a yellow tinge to their screen, or a blueish mark, which seems to be caused by overheating of internal components during charging. Admittedly, most of them may be Gen 1, but I've seen a few Gen 2 as well - so I would err on the side of caution, or at least monitor the heat if you're going to use a non-stock adapter or charger. I find I don't really need to charge to 100% anyway, even a charge of 80% or even 70% will be sufficient to get me through most days.
EDIT: I have also seen people reporting a full charge 'in about an hour' (maybe on reddit?), but that has never been my experience, so can't say whether it's possible or not.
Okay, thank you for the interesting info. Obviously it is not worth the risk of getting the watch damaged. I remember that my previous unit of Moto 360 2nd was significantly warmer than this new one. It might have been related to the fact that it eventually broke down and I had to get a replacement.
Anyway, I'm probably buying a faster charger anyway for my phone, so I might as well try it on the cradle and post the observed results here in case anyone is interested.
A little update: I found this https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/100824
Motorola clearly states that the charging time is about 2 hours. So I guess trying to charge it faster might really have undesired outcomes.
They strictly recommend to use the provided adapter only. Which is a problem for me because the US adapter is incompatible with the European sockets. But I don't believe it'd make so much difference. Also I haven't noticed any overheating while charging, I don't even remember being it warm.
The owners manual for my gen 2 states that it should fully charge in 90 minutes but it's always taken at least two hours. After I received my warranty replacement, original failed at 24 months at end of extended warranty, I stopped leaving my watch on the charger and removed it when it reached full charge. That was two years ago and now its starting to drain faster during the day which tells me that a battery replacement is just around the corner. I'm not certain that I want to invest any additional money into this old unit.

Hi guys
I'm an iphone 3gs owner at the mo but my contract is up in a week and after doing A LOT of research over the past 3 weeks, i was pretty much decided that the GS2 was gonna be my next phone.
Then i foolishly visited the xda forums! lol (in fairness, it probably still will be my next phone).
But seriously though, setting aside the various issues some people are clearly having (reboots, battery drain, etc) what shocked me the most was hearing about the low-powered charging mechanism (apologies if i've gotten this slightly wrong).
I've heard that it only charges at ~650mah, but that the phone can easily surpass this under load (~850mah?), meaning that you could be charging the phone at the same time as using it, only to find the battery going DOWN. Can someone confirm if this is true? If it is, then i'm gobsmacked that Samsung could make such a c0ck-up. Imagine if you're using the GPS (a real battery hog) while driving (and plugged-in to the ciggy lighter) only to find that the battery dies before you get to your destination! lol. I've heard about the heat this puppy produces, i wonder did they limit the juice to stop it from burning a hole through the floor
Even though i'm bored to t1ts with my iphone (and i hate apple), what i love about it is that when i don't actually use the phone for extended periods of the day (which is quite often, due to work) it still retains it's charge really well (i get insanely good battery life). I would be really annoyed if i found the GS2 battery dropping any more than, say, 30% over the course of a busy working day (say 9am to 7pm) with virtually no use.
So, to finally get to my point! My iphone charges REALLY fast. I'm worried that it will take a stupidly long time to fully charge the GS2. Can some kind person please do an experiment for me, and see how long it takes theirs to fully charge (from fully dead to 100%) with the screen off and the phone not doing anything major in the background?
Also, it would be good to know how this compares to the GS2's competitors.
Sorry for the long post guys!
my phone is at 33% at 8:08
Will let you know how I get on. I have it on charge now
I think mine takes around 3 hours from empty using samsungs supplied charger but I will try to do a test for a more accurate time. How does this compare to the iphone?
Yep mine takes about 3 hours as well from empty to about 90% using the wall charger, then it goes on trickle charge the rest of the way. This is on standby as well.
Yepp takpes about 3 hours to get fully charged. however, i've been using the phone as a wifi hotspot all the time and yes, it increases charging time but it doesn't really matter when it takes so long anyways

65% at 9am
It takes almost 3.5-4 hours to charge it with stock charger from empty to full.
It takes a bit more than 5 hours to charge from empty full using USB charging in my laptop.
Found out the hard way:
Charging with original EU charger AND heavy use (downloading, Wifi tethering, map ops etc.) MADE it drain faster than charging.
Two nights before left it during night with orig. charger and made it in 8 hrs only to 84% while on.
With Hama 0,8 amps charger full in 2hrs from empty and stays full even with heavy work.
NO heat issue though !
Methinks the charger is crap

if you look thru the battery driver source code, samsung capped the charging at 650 mA it seems. not sure why, other android phones use the full 1 amp.
so samsung either saw a heat problem and lowered it, or that's just the way they do their phones charging. who knows.

Wow, ok. As someone who uses 3G a lot when our internet connection goes down (all too often), I hope the charge will end up keeping up with the battery drain. Otherwise I'll be tempted to change that source and probably end up frying my phone (if it ever gets in stock :|)
Thanks for the info
[Q] How to charge battery properly on first time usage & is a converter adapter okay?
Hey guys. I have two questions for ya.
There seems to be various opinions on how to properly charge the battery when you first get the S2.
I seem to here two ways:
1) Charge the battery fully (maybe a good 8 hours? Anyone have a good value?) BEFORE first usage. Then you can go ahead and use it. <--- I was taught this way back the early millenium with all the new fancy cell phones.
OR
2) I assume there is probably going to be somewhere between 50-80% of battery life before you even put the battery into the phone. Thus, one should use up the battery until it drains completely. Then recharge it back up to full again. And vice versa.
Which is the correct method of choice as far as preserving battery life? Does it even matter?
My second question deals with whether an adapter for the battery charger would be okay. Like many of those who live in the states, we have to import the S2. I bought mine from Expansys-USA, which gave me a UK/European model adapter and then a generic converter (for converting UK/Europe to US/North America). Anyone know if this is okay for the phone or battery? It seems like there would be an "extra barrier" to prevent the phone from charging 100% accurately or properly. I do not know too much about electrical engineering, but it just feels like the Europe-to-NA adapter is acting as a sandwich between the phone and the outlet.
Should I go as far as buying an adapter from Canada (if they have one available) to ensure maximum charging compatibility?
I have always charged my new phones for 24 hours (roughly) then used it until it went down to 10~15%, then finally do a four+ hours charge (doubling the time it took to reach full charge). After that I charged/discharged as needed. Phone batteries have moved on since my first phone, but I still use this method.
It is not really proof but a colleague bought the same phone as me at the same time a few years ago. I did my usual routine, they never bothered (even though I told them). After about a year their phone wasn't holding the charge as well as mine (for roughly the same amount of usage).
The adaptor is rated from 100 through to 240V and 50/60Hz. So basically it works (nearly) anywhere you have mains electricity. There is no effect on charging. My old HTC HD2 charged fine when I was on holiday in the USA. So no worries.
Given most (all?) phones actually cease charging the battery completely once it reaches full charge, I don't get why they recommend you "charge" it for some inordinate amount of time the first time.
Hence, there seems to be 2 schools of thoughts here. One for charging and one against charging upon initial usage. Hmm...
On another note, according to this 2000mAh battery pack located on eBay: http://rover.ebay.com/rover/1/711-5...at%3DSee-All-Categories%26_fvi%3D1&_rdc=1
"Initially new batteries must be charged for 14 - 16 hours continuously. All batteries require a "break-in" period, so don't be panic if your battery doesn't hold a full charge right away. For the first 3 - 5 cycles, please make sure to charge the battery fully and drain it fully before recharging. This will properly condition the battery and will ensure that it will operate at its maximum capacity."
Not sure what your guys thoughts are, but this sounds like a plan to follow for the paranoid users like me, eh?
For those of you who have the wireless charger. Do you notice a significant battery life shortage when you charge the phone using the wireless charger? Ever since I use the wireless charger, the battery life doesn't seem to last as long as charging the phone using the traditional route.

I just got mines today from AT&T. Will keep an eye on how it last and let ya know.
I've been using the charging stand for a week or so and haven't noticed any difference.
I've been using mine for over a week, and I've noticed the phone charges faster than with the USB cable (to the wall outlet), and the battery charge seems to last just as long... maybe you have a bad battery?
also, I found this on wikipedia about the qi standard: "Regulation of the output voltage is provided by a digital control loop where the power receiver [phone] communicates with the power transmitter[charger] and requests more or less power. "
I have a thin plastic case. Do I need to take the case of to charge the phone? want to know before I buy
I've actually seen a slight improvement when using the charging plate. Through my typical usage during the day (7 a.m. through 6 p.m.) I was coming home with 50% battery. Now, I'm coming home with about 70%.
Don't be too impressed though. I don't use push on anything at all, and I don't use any kind of social media.
I'm betting you have a defective unit. My first 920 did exactly this. I would set in on the plate, take note of the battery percentage, take a 10 minute shower, come back, and the percentage jumped from 88% to 100%. There's no way it could charge that fast. Not even the USB cable can charge it that quickly and that charges at a higher amperage and voltage than the plate. Sometimes I saw it jumping from 95% to 100% in a matter of seconds. So I called AT&T and after countless hours of talking with employees that knew nothing, I finally was put on to someone who helped me get the phone exchanged. My new 920 does not have this problem and a full charge on the plate lasts just as long as on the plug. My first 920 barely made it 8 hours with normal use (texting mostly). My new 920 makes it past my 8 hour shift with 75% to spare.
Had to replace mine. White light on the plate came on but no response on phone. Wireless charging coil was faulty... Inductive charging failed and that sucks... It wasn't a bad flaw but when I spend 450 I want a functioning device. Now, I have it.

Yes. I used the original charger and cable. When I let the screen on while charging, it seems like its just preventing the battery run down, instead of adding more charge. I guess I got a defective battery. When the screen off, it just take too long for full charge, like almost 9-10 hrs. I test the cable and charger with another device it seem working fine. How long it take for you to do full charge when screen of btw?

I don't know exactly how long. But charging and using the device at the same time is no problem and adds charge at an ok rate. I would guess that a total charge would take around 4 hours but it is a guess.

I did some research and this is what I came up with...
-- the USB charging seems to be hard-limited to a maximum of 500mAh intake. This is consistent with the original USB specifications, although no one really adheres to those anymore anyways. Charging with 500mAh is bound to take a long time and presumable even light usage (screen-on + sufing) will prevent charging at all and still drain the battery or keep it at the same charge level. I consider this a quite major design fault and wonder why Sony did this - if they had any strong reasons (overheating near USB port due to the thin build and no heatsink properties of the material?) or if it can and will be adressed later on by software (I am not sure if that is the case...)
-- this also means that using different chargers (if they work at all, the Tablet seems to be picky and did not make use of two generic ones that were tried, only a HTC wallcharger was accepted next to the original Sony one) that put out more than those 500mAh will either not work or they will deliver just the 500mAh the USB port accepts as a maximum
-- however the charging cradle contacts will readily charge the tablet with up to 1500mAh
If one were to assume the worst of Sony one could say they probably limited the USB charging to a minimum to push the sales of their original chargers. On the other hand one can argue that SLOW charging is actually better for the battery longevity, so Sony could defend that move with that reasoning...

There is a thing that while playing "heavy" games and charging from usb connected to pc it even dicharges. If connect it to stock charger (1.5A) it manages to charge but very very slow. There are chargers for 3.1A or even 5A which will charge your device very quickly.

Just got mine XTZ and so happy with it, but same thing it take so long for charge it even with the wallplug.
I just notice, i have the XZ and if i use the cable directly on the phone it take a long time for charge it too. But if u use the dock my phone charge in less than one hour ( or maybe a little bit more), So i can guess is a usb limitation on the sony product (or maybe a marketing trap)
Sorry for my English.
In my case, since i've the Galaxy S4 ATT version, i use that wall charger i've not tried the one that comes with the tablet but the S4 charger is a 2A while the Tablet Z is 1.5, with the S4 one + stamina mode + auto brightness + special mode(only 1 core running under clocked to 1036Mhz, conservative governor) my tablet charges ultra fast from 10% to 50% in 1 hour and half or even less, also my standby time is up to 8 days at full battery.
If you have your tablet rooted and you want to use my special mode, just download CPU Adjuster from Play Store, give it root permissions, then create a screen off profile, 1 core, max 1036Mhz and that's it.

why should it be like that? We have a 6Amp battery in there and if it WOULD charge all the time with 500mAh max we would have a charging time of 12 hours. But if the battery reaches 80% charge charging will be much slower. That means if your statement would be true, we would have charging time of over 14-15 hours.
I charged mine in 6-7 hours. 6000/6=1000 so it´s normal for our 1,5 Amp charger.
Okay, tested it. Shorty story is, there is no difference between charging via dock and charging directly via USB port.
Long story:
- variation tested: SGP312 (WLAN 32GB)
- Battery percentage at start: 58%
- Charging time: 70 minutes
- Charger used - the one which came with the Tablet. The dock does not have a charger in either case, you have to use the Tablet one (which I do) or a 3rd party charger for it.
The only difference between the tests is that once the USB cable went directly into the Tablet and once the USB cable went into the dock.
Battery percentage after 70 Minutes with USB cable: 80%
Battery percentage after 70 Minutes with Dock: 81%
So basically, it got from 60 to 80% about ~1150mA / hour independently of the charging method.
As a sidenote, bringing it from 80% back to 58% took 28 minutes of playing a 1080p mkv at full display brightness,
Bought this tablet yesterday after finding it for a €50 discount and reading some reviews. The reviews warned that the charger is a but underpowered, and they weren't kidding, after 15 minutes of being plugged it I've only seen it go up 3-4%. Worse yet, if I try to actively use the device (just some browsing, nothing intensive), the charger can't keep up at all and the battery charge starts dropping again, slowly.
I'm quite happy with this tablet, it's got a nice feature set, good performance, decent price; I don't want to return it. But not being able to use the device when the charge gets low is a bit of a deal breaker. So I'm left wondering.. is there a way to charge it quicker? Would a 3rd party charger with higher amp output work? Or doesn't it work that way?
be sure being charging with original charger and usb cable
I was having same issue during the first month with this device, i was charging it with another usb cable (much longer) else than the OEM one, My device took 10 to 12 hours to do a full charge, very annoying thing. After some thinking and asking other ppl about this issue, tried to charge xtz with the charger and usb cable included in the Box and voila, not only the charging time has reduced to no more than 3 hours, right now i can use the Tablet without no intensive power requierements (wifi browsing with minimun screen intensity) and can see how the charging state increase during use... Hope this can help u.
Thanks for the reply! Sadly I'm currently already using the standard USB cable and charger that came with it, but maybe my cable is just fault or something. As far as charging rate goes, 3 hours sounds like what I'm getting, so maybe my expectations are a bit high in that regard. On the other hand it seems like I should be able to at least use the device when it's plugged into the charger without running out of battery charge (even if much slower). Almost seems like it's just being drained abnormally fast, but according to the battery usage thing, ~90% is used by my display which I guess is normal
