Anyone know where to get an extended battery? Thanks.
I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!
you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back
I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery
I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?
You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.
What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?
I'm running the 12/28 CM10 nightly, and I'm having an issue with charging my battery. When the phone is on, the battery charges normally to 90%, at which point the LED changes from red to green, indicating full charge. If I leave it plugged in, the phone continues to charge to 100. However, the battery doesn't really charge past 90 because once I begin to use it the charge drops really quickly down to 90. Similarly, if I restart the phone, even if it said 100 before, when it is on again it says 90. I have had this issue with previous CM10 nightlies as well. It is a software issue, because if I turn the phone off and charge it, it charges to 100.
Any ideas on how to fix this? Thanks!
This is a suggestion out of the blue but maybe try recalrubratung your battery

This is the intended bahavior. The type of battery used in phones last longest when they say between 80% and 20% of charged. So your phone will pull the maximum amount of power it can until it hits 90% then reduce power draw to a trickle charge.
The rapid drop is power is often the chip in the battery lying that it is fully charged when it is not. That is why you may see a rapid decline to 90% where your battery drain will go back to normal.
You might also see the phone telling you that it has 15% power then turning off. Upon reboot it will say it's at 0% or 1% that also is the battery trying to protect it self from damage.
This is a simplified explanation of how all phones work these days. The only difference you'll notice is how good the software is designed to lie to you about the power level. If it's good you won't notice these types of anomalies but they are still there.
Have you wiped battery stats?

Thanks for that informative answer. So I take it that means there would be no performance difference between turning my phone off, charging it, and then using it (with it saying 100%) vs leaving it on, charging it to 90% (green LED turns on) and then using it?
Anyone having charging issue. I ran my shield battery down when I first got it. Then I plug it in to charger. Its been charging over 8 hours and still not at 100 percent. took it off charge at 80 percent. No way it should take this long. I read on reviews it took like 4 to 5 hours.

That sounds really odd. What does the battery usage say for the device? Was it awake the whole time? Does it think it was charging all night?

I feel like that has happened on my nexus 7 before. I bet it is an android thing. I would try again and see if it acts up a second time.

when I was charging, i close the screen. so it went to sleep. I dont know how you can tell if it think it was charging all night. I went to battery info and its said 13.6 hours on battery. and 48 percent of that was screen usage. rest was on game and apps.

1. Sometimes the battery indicator on Android can take a while to figure out your battery. It might drop 5 percent in ten minutes then take an hour to drop 5 more.
2. The vent area on my Shield seems warmer than the surrounding plastic even when in sleep for a while, so it may be drawing more power than is charging. Just try turning it off and charging it.

Which vent area? Front or back? Because batteries do warm up when you charge them, and those are some big batteries (and a full 2 amp charge)

The smooth part on the bottom back with the model number, FCC, etc. And it's not when I'm charging but when the lid is closed. If I manually power it down then the warm goes away.
i never recommend running your device down when it comes straight out the box. usually i tell people to just fully charge the device first before running it dry therefore it can register the full battery, personally i would not leave a device connected over night just for the simple fact that it can be one in a million that the device might get screwed over a long period of time.
it be nice to know if the problem is fixed or not and what you did just in case others run into this same problem.
ive had no charging issues yet. batts do tend to get nice and warm tho.
but for what its worth i just noticed that im still getting notification sounds from my Shield even tho the lid is closed. so maybe its some kind of hybrid sleep and if you have some rogue app pulling a ton of CPU cycles & its not going into full sleep so its taking longer to charge?
just some food for thought on your issue

Like most Android devices, the device goes to "sleep". Unless you power it off, it still handles notifications, and it still talks on WiFi. But it should consume very little power.

Modern devices use LiPi or Li-ion batteries, these explode when overcharged (seriously, youtube search overcharge lipo). As a result all devices sold with this kind of battery have charge monitoring tools and will disconnect the battery from the charging circuit when full, also they should then run purely from the mains power when the battery is full rather than running on the battery again (they don't like the repeat connect/disconnect effect that would lead to). End result, can't overcharge it.
The heat on mains power tends to be from the voltage regulator. These devices don't run on 5V power like comes from the charger. They tend to use a combo of switch mode and linear regulators to drop the 5V to 3.3V for the CPU and peripherals (3.3 is most common at any rate). Linear regulators in particular get quite warm. Switch mode regulators don't get so warm but don't give a clean output the CPU will run nicely on, they have the odd drop or spike which would either reset or fry the CPU, so generally what happens is the switch mode reg drops a large chunk of the voltage and then feeds it into a linear reg to drop the rest of the way (*the less voltage a linear reg has to drop the less heat it produces). From 5V to 3.3V it is most likely going to be purely a linear regulator, with the CPU and screen drawing at least 1A of current and a 1.7V drop that would equate to 1.7W of heat produced, not much, but enough that if you were to put your finger on the bare regulator chip it would come away red, hold it there long enough and it would be somewhat like those competitions kids have over who can keep their hand on the hot radiator longest That is the main reason they will get hot.
The batteries in these devices are usually 3.7V, that would need a separate regulator from above, and another regulator would still be needed to go from 3.7 > 3.3. 3.7>3.3 would not get so warm. 5>3.7 would still be warm as above.
Never fully drain a LiPo. Gets too low and you damage the cell ir-repairably. When the device claims it is at 0% charge and shuts off is usually closer to 10-20% charge. But that is still considered too low by some people. General advice if you want to prolong the lifetime of your battery is to turn the device off and charge it when it reports somewhere around 5-10% charge.
Batteries do get warm while charging. But my bet is that the voltage regulators would be far more significant heat producers.

good to know. :good: i didnt think closing the lid was the same as pushing the power button on my phone to turn the screen off.
but the OP's problems still might be "sleep" related.
prime example my SGS3 batt life started to tank after the 1st VZW JB update. it took twice as long to charge & would never "sleep" (cuz of the OS not a app) but since the Tegra 4 is a much higher profile chip it could suck a bit more juice if its not being aloud to fully sleep, for whatever reason.
like you said tho, looking at the battery stats could easily tell us if this is the issue.

yes while all this your saying is true i still wont risk it. i say this from experience had a note 10.1 and would leave it over night charging and sure enough it ended up screwing up. might of been there was something wrong with the device itself but still. good post on your behalf though :laugh:
but still im paranoid and prefer to just disconnect once its charge it wont hurt

I tend to go into way too much detail sometimes :/
Disconnecting can't harm it at least if that's what you prefer.
As for info source. Quite into electronics and robotics, intact the shield would make a good controller for robotics purposes
well i did my second charge last night. and this time much faster, about 5 hours to 100 percent. guess i dont have a problem after all. dont know what happen the first time.

no worries lol i tend to get spaced out at times and go into details does not hurt to enlighten people :good:
Can anyone help and give me tips on how to stop my screen and mobile standby using so much battery,, also im using official moto charger and getting 7 hours until fully charged without any apps running, am i doing something wrong here
Thanks :good:
Mobile Standby is based on cellular signal strength, the better the signal the lower the battery usage, in general.
Screen should be the primary battery user, but you didn't give us a screenshot of your screen on time to make a fair comparison if it's normal or not.
The charge time is messed up though, mine takes less than 2 hours from under 10% to full if left idle, try another cable or charger with 1.2+ amp supply and check the USB port for lint buildup, I have seen excessive pocket lint build up and keep the cable from making a good connection.

Unfortunately, that screenshot doesn't tell us much because you have been charging partially off and on (statistics are since the last full charge), but I think your statistics are off... they add up to way more than 100% in the first screen shot, but I would expect the screen usage is normal since you are using the device quite a bit. The only way to get the screen to use less power is to turn the brightness down, otherwise that is one is and should be the largest battery user.
And even without a SIM the device will still look for mobile signal, it is capable of making emergency calls and to my knowledge in the stock ROM that cannot be turned off.
Thanks for the reply, sorted the charging time problrem out and lowered the brightness down to 10% and im still getting alot of usage also just to clarify i cant really do anything over the screen consumption?? Thanks :highfive:
New moto G 3rd Gen in the household. Is it not unusual for the shipped charger to struggle to charge at all when screen is full bright and wifi all radios are active? My son reported the phone would not charge at all. eventually went flat and had to use the Vol-DN/Power combo to revive it for him. Seems to be charging fine now with the supplied charged with the handset powered off. I suspect he had overwhelmed the charge by pegging everything full bright and on. Is this about right for this phone?

Sadly, this isn't unheard of... The charger that comes with these in the box is garbage in some parts of the world, check the rating on it, if it's under 1A/1000ma get a decent aftermarket one rated at 1.5A or better.

Thanks. Good advice the supplied charger is only 850ma. Will get a more powerful one.
I also wonder if the battery charging has some conditioning login going on in the first few cycles.
Last night I observed this weird behaviour as the phone charges.
-Motorola SPN5512A Phone USB AC Charger Power Supply 5.1V 850mA.
-Phone off.
-Pressing power button intermittently to display battery graphic and charge level.
It charges fine to somewhere over 51% and then begins to discharge rapidly whilst phone is off and charger is connected !!
At this point the screen remains on with charge indicator permanently displayed. Phone is still switched off.
This is a log of how it was charging, with me doing a quick press of power button to read the level.
5:24pm 35%
5:34pm 41%
5:46pm 48%
5:56pm 51%
<- In this period phone which is still powered off, spontaneously begins to discharge
7:20pm 30% screen on and battery icon displayed permanently. Phone is still off though. pulled charger and re inserted @ 7:21pm
7:31pm 36% now charging again with screen going off and the need to press power button to see charge indicator.
7:36pm 39%
7:45pm 44%
7:55pm 50%
8:17pm 62%
8:46pm 79%
9:34pm 95%
9:47pm 97%
10:13pm 100%
Any idea why it would have flipped from charge to discharge?

Thanks for the reply, i dont have a sim card in my phone though i use it strictly on wifi and screen attached

If you don't have a SIM card, I recommend putting your phone in airplane mode to keep the cell radio off. You can turn WiFi on after enabling airplane mode.
I was just about going to create a thread about it. My battery takes a full night to fully charge even with the phone turned off. What can I do so I can improve it? It is pissing me off seriously.
How's your sot on this latest firmware guys and did you notice any improvements from 3.81 firm version? I'm on 3.81 and I'm disapointed about the battery life. It's too short...

And it does not load you anymore? Phone? From 90% to 100% over half an hour?

Does 90% to 100% battery charge for a long time? About an hour you are loading these 10%

I really don't know what you're saying. Sot means screen on time. On the 3.81 firmware I'm getting about 4h sot, just browsing, youtube mainly on wifi, a little bit of data traffic. 4h, no games with screen brightness at minimum is just pathetic... Bad deal with this phone...

He's probably saying that his phone takes too long to charge from 90% to 100%. With that said though, I have yet to update to the latest version.

Even without updating to the latest version, I sometimes experience that phenomenon. Heck, my phone sometimes blatantly stops charging for no reason at all and I would have to turn off the phone to be able to charge it.
No problems for me thus far, but the battery is extremly week. I wonder if undervolting the cpu would increse a little bit the life per charge cycle... Anyway, I regret buying this phone, but it's my fault entirely that I did...

Today I experienced the same unfortunately ... I plug the charger and nothing the diode is not lit and there is no sound that loads, under the computer immediately detects and charges ... I have to turn off and turn on the phone to start charging, strange is enough

Probably you have a bad cable, charger or even the inside charge circuitry could be bad...

Unfortunately, my problem escalated quickly. The phone isn't charging anymore and I've tried different cables and chargers. It seems like my xa has a hardware problem, thankfully though I haven't rooted and unlocked the bootloader of this thing. Gomna have to send it back for warranty.

I think it is because QNOVO ADAPTIVE charging
That adapts your charging behaviour
Like many of us leaves the phone to charging over full night that damages the battery
So sony added a featutre qnovo adaptive charging that adapts charging behaviour and if someone is one of those people who left there mobile to plug in full night
It will automatically decreases charging speed from 90 to 100 %
