I just recently bought a 3500mAh extended battery from amazon. (http://www.amazon.com/gp/product/B0042TY68C/ref=ox_sc_act_title_1?ie=UTF8&m=A1N1UQZS4G6GV9). I just got done fully charging it, i let it charge fully over night, just unplugged it and boom 10 minutes unplugged with me not even touching it just letting it sit on my desk we are down to 95%. I know you are suppost to cycle these batteries and stuff before u can actually see the fully life of it and i plan to do that. My question is i downloaded battery monitor widget and on the main screen its calling the battery a techno-Li-ion 1425/1500mAh battery. I know this isnt right ive cleared battery stats probably 10 times total now, through recovery and through the battery monitor widget app. Im hopping i didnt get ripped off and it just takes a few discharges for the phone to recognize the new battery? Any help would be appreciated.
I plan on letting the battery get to 15-20% and then charge it all the way up again and do these a few times, as well as clear the battery stats. This is what i read to do with new batteries? Please correct me if im wrong..
When using an extended battery you are not going to get a full charge unless you condition it or you could use a SBC kernel.
how much will u get out of it then without the sbc?
I bought this exact same battery. I used it at the time on my Evo unrooted. The first one that came to me (2 weeks late) wouldn't even power up. The second one they sent me I ran for about 3 weeks and put the stock battery back in. I was about to get 9 to 12 hours on my stock battery and with this extended I was getting the same. 2 weeks into using it the battery life got crappier everyday. To me it wasn't worth the added bulk for the same or less life. Since then I now run CM7 on the Tiamat sbc kernel with my stock battery that is almost a year old and get close to 18-20 hours out of an almost year old stock battery.
I use the SBC kernel, battery monitor widget, and the 3500mah battery. The thing lasts for days. Literally. When the green light comes on at "100%", that means NOTHING.
I ran it stone cold dead yesterday on purpose. Plugged it in at 10:00pm using my 800mah AC charger.
10:00pm: Plugged in, begins charging at ~700mah (max for my charger)
12:45am: Phone indicates 100% @ 4018mV but keeps charging at 700mah
2:00am: Charge rate ramping down @ 4197Mv
2:45am: Charge rate 100mah
3:00am: Charge rate 50mah
4:00am: Charge rate 15mah
4:30am: Charge rate 10mah which it remains at when fully charged (4198mV)
Stone cold dead to green light was only about 3 hours. BUT, stone cold dead to actually fully charged was really double that.
Obviously if the battery isn't dea, it will take conciderably less time. If you charge it with a PC, limiting the total current to 500mah, it will take conciderably longer.
So battery monitor widget calling it a 1500mAh battery doesn't mean anything? Right?

Ahh... yes. I know now which one
I have the exact same battery and I'm wondering is the percent shown total BS? Mine is showing 87% with 4000mV left after charging overnight with an SBC kernal.

Yea I'm at 8hr40min as of right now @ 17% battery. I've had my display backlight turned down and have been at work the whole day doin nothing with my phone but light texting and posting in this thread. With my stock battery I get around 12 hours before the phone almost dies with regular/mild use.I'm starting to think this battery was a rip off.. hopefully once I charge it back up it will last longer but idk... If anyone has any tips or tricks to make this battery last longer please help me out.

FYI, after 12hrs, i'm only at 70%. That is with very poor signal at work all day, and playing pandora on the way in.

The newest version allows you to override that. Previously, the phone was telling it the capacity was 1500mah because that what the normal battery is supposed to be. The new version let me change it to 3500. So the % estimation should be accurate now. It is claiming I have 70% remaining or 2450mah. And 70% of 3500 is 2450. Now, where it came up with 2450, I have no idea.
The first time after ur charged the battery when u got it did u let it completely die or plug it in when it hit 10% or so?

My first full charge on the same battery I got the exact same behavior. I was on the Stock Kernal that came with CM7.
Second charge, after changing to the Tiamat SBC, my battery is screaming... 6+ hours of heavy usage (video, web, lots and lots of text and 30mins of calling) and I am still over 50%. By now, I would have had to charge the regular battery...
Very pleased with this thing...
well im about ready to unplug mine for the day and see how it goes, i fully charged it with the phone off with a wall charger. And have been cycling it witht he phone off by unplugging it when the light turns green, waiting for the light to turn off, then plugging it back in until the light turns from orange to green again. Ive been doing this for the last hour or so because somone in another thread about this battery said it help him out alot, i did unplug it when i first woke up and it dropped from 100 to 92 within 3 minutes so thats when i tried this cycling, i did unplug it in the middle after doing a dozen or more of these cycles and it staid at 100 for quiet a while then dropped to 99 after about 5-6 minutes of being unplugged and me browsing the web and market this being a huge improvement so id have to say the cycling of the battery does help idk how or why but whatever im not complaining ill post back later tonight once i see how the battery acts.
So far I've had terrible luck with this battery can't get more time than stock. Charging it with an SBC kernal and it doesn't help, was avoiding spending 60 bucks on a battery but I think Ive no other choice.

im at 2 hours with it right now, down to 70% i used it pretty heavily about 30min ago to reflash cm7, savagedzen sbc kernal, download all my apps, setup launcher pro plus, and re confiugre everything. It dropped rather quickly from 100 to where its at now so i guess we will see, BMW is estimating 10hr40min remaining battery life right now which would put it at about where my stock battery would die at around 12-13 hours, so we will see :-\
*edit*
BMW now saying 12hr10min at 70% battery? weirddd...
*edit*
BMW now saying 16hr23min at 65% battery, ive been using it moderately, used 4G for a second and WiFi for a few minutes as well...
Here's why the drop...the Evo along with other phones use bump charging to charge the battery meaning when the light is green you have anywhere between
90 and 100 percent at 89 percent down to zero you should not see such a dramatic drop...its a Evo thing the large drop

go into bmw, go to settings, monitoring preferences, second from the bottom battery capacity, just change that value from 1500 to 3500, took me a while to find it as well.
I hope it's not just my phone but does it take a long time for you guys to charge from 0-10% to 100% battery life? I'm not even exaggerating but it takes about 4-5 hours for my phone to fully charge.
1) I charge it through the wall outlet. I have no problems charging my 4S on the same wall adapter and outlet.
It takes me max 2 hours. Through the wall
It takes me just about 2 - 2.5 Hours plugged into the wall. I have the standard battery.
Crap, must be a defect with my battery =( I'm timing the charging right now and its been 55 minutes and it's only at 27% Started from 0%.
It takes me 1 hour and 40 minutes to charge from 0 to 100 with the wall charger ( GSM version)

You could calibrate the battery ( charge to 100% and wipe the battery stats in cwm ), if that doesn't help i would go back to the store and ask for another battery cause it should charge from 0 to 100% in 2 hours max
Sent from my Galaxy Nexus using xda premium
the rate of chaging is depending on the output current that your charger have... my original charger have a rating of 5V 1A 0%-100% requires me a good 2hours leaving the phone ON in standby
5V 700mA chargers gives requires me 2.5 hours from 0-100%
Takes me less than 2 hours to go from about 15% to full 100% charge on the GSM GNex.

Since getting another battery would be a hassle for me, I decided to root and wipe my battery stats like you instructed. Wasn't planning on rooting or anything since I wanted to run stock for awhile but let's hope it fixes the battery issue. Thanks for all your input guys. Appreciated and +1'd for all.
Cdma GNex here. I've been a nexus user since the nexus one. This is bar far the fastest nexus charging phone if not phone in general that I have seen.

Just this past week I got two of these extended batteries off of Ebay. Although I'm still calibrating the one seen on the charger. I really haven't found anything concrete on how long a battery like this is suppose to charge for? I've read things such as charge it in the phone (which the phone will charge it as if it's the stock battery) use the charger that came with it (charger in the photo continually thinks that the battery is at full charge, when it was in the phone until it died.) To battery calibration apps which I'm reading don't do anything, to bloatware. So if anyone can help me out, it would be great. And sorry if I made any mistakes in this, sending this from my phone is kinda hard for me.

I have the same extended battery and I can say that I have no idea. I'm using custom roms, and a charge lasts anywhere from a day to 3. I would say charge it in the phone til full, then drain it by using it, and do that a couple of times, it gets better as time goes on.

I have the same battery and when I use the phone to charge it it takes 6 - 7 hours and it lasts pretty good but since I've installed the shot of awesomeness by team inferno the original battery is good enough for my day... My max was 1d 14 hrs 10m 20s with 2% left... Big thanks to team inferno!!!
Guys this issue is annoying me. My device is having some charging problems. I have measured the charging time for last two charges, and its taking 3 hours 40 mins for 10% to 100%, and 4 hours from 0% to 100%. Where most people are saying it takes around 3 hours, from a complete drain to full 100%.
So have any of you guys ever measured the actual time of charging? A lots of comments I see say around this or around that, or from 2 hours to 3 hours, well that's not what I need. If anyone has measured the time then please post here. I'm thinking about going to SC, but I don't wanna go there until I'm totally sure that there is a problem.
PS: I'm talking about Stock charger, (2A) plugged in AC power source. And device should be on, not off.
Btw- There should be a technical answer to this, the charging current is 2A and the battery is 3100 mAh, so how could I do the math?
Thanks in advance.

I don't know the math stuff but why don't you try calibrating the battery - worth trying !
Knowing that info is only half the truth. How the phone charges the battery and how much energy your phone uses during the charge matters too.

The time taken to charge is a pretty simple mathematical formula. But the rest of the calculation is complicated.
If you phone is on, how bright is the screen, is the display on or off, are you on wifi or network data, are you syncing email every 15 minutes or every hour, are you using the phone to send messages during charge, have you got gmail, dropbox, facebook, instagram, whatsapp, etc etc etc all doing a sync at regular intervals during the charge?
All of those things will use up some of the charge as its going in, so the charger is fighting against you.
I've been charging off usb at work and struggled to gain 20% in 8 hours because of my usage pattern.
Theoretical time for charge is about 1:30 hrs. Reality, start and ending charge should slow down (for safety), heat slow downs, plus usage of phone as spoken above I guess it could take up to 3 hrs.
It's not great to do a full charge regularly. I tend to keep mine between 40-90% for maximum life cycle of battery.
Perhaps try resetting battery stats? Try a different 2a charger?

1:30 hours? Could you kindly explain how?
And I've wiped my device fully, also reseted battery stats.
One thing I'd to next is, I'll turn the device off and see how long it takes then.

Mine takes 2.5 hrs to charge from 10% to 100% with phone on using stock wall charger and cable (when charged continuosly with no activity on phone). It charged from 1% to 96% in 2.5 hrs with phone switched off (switched it on exactly after 2.5 hrs to check). But, usually i avoid charging my phones to full 100% (also always charge it when at 10%).

Try with another note 2 charger first. The thing with these chargers is they will behave erratically when there is voltage fluctuation or if you use in a train and other cases. So go to SC and tell them its taking almost double time for me to get charged. They will replace the charger as well the cable. My cousin has the same problem with s3. He got it replaced by the SC.

Thanks Chaitanya. But the SC guys are so stupid here. First thing they do always are to take the phone in their custody and deal with it badly. Still I will ask them to replace the charger and check.
Some of us have noted that if you let the screen time out and not manually shut screen off after connecting the charger. ..The charging is faster. . If you manually shut off the screen. .. The charging is slow.... It is weird but don't know why. .it definitely is happening

Op: I said theoretical it will take 1:30.. Realistically it should slow down during stages due to safety reasons.
Mine took probably 3 hours the other day I ran it down, but this was combination of using 1a and 2a charger.
I think on the note 2 it doesn't ramp up power till it gets to 20-30%. Took a while to get there from 2%. If only battery widget was working on the note 2..then I could confirm.

Are you using the charger that came with Note2 ? I was using my old blackberry charger and it took for ever to charge the phone.
The output of the Note2's charger is more than twice the output of my blackberry charger.
^ Yeah, of course I am using the stock charger that came with Note 2! I'd not create this topic if I had used another charger.
Anyway, after a long week in Service Center now my phone is back, they provided me a new charging adapter (not the cable) and I was very happy because I thought everything will be smooth and like before but guess what? No improvement. It's still taking long! I just measured it for 30 mins exactly, it went from 70 to 83%, i.e 13%, where it should be 24% as stated in this thread,
http://forum.xda-developers.com/showpost.php?p=33585646&postcount=31
Now I am really angry. I will try with another Note 2 USB cable first, if that fails, there is something wrong with the device, I guess?

I really don't think it's your device or your battery for that matter. I have a question as well (sorry to hijack...). When you were charging it for 30 mins, were you using it? Was the screen off or the phone totally turned off? I noticed one night that I had an email notification and the phone did not charge because the notification LED was on all night while I slept and it was plugged into my 1A Samsung charger from my original Note. I have yet to check if the charging disconnects itself if the LED comes on. I don't even know if the phone charges at all if the screen is on either. Can anyone confirm? I guess I'll try it out tonight! The battery last forever I got to admit, perhaps most of the time I'm slow charging it at 1A max with the original Note's charger? I guess it does the battery some good
Thanks a bunch!
No pal I am not using the device while charging (because I am testing and measuring the times, that's why I restrain myself from touching it), and it's on, not off.
Anyway, yesterday I went to a friend's home and found he has a Samsung ACE and has same USB port like Note's and I was carrying the charging adapter, so I took that Ace's cable and plugged in to my Note's adapter and let it charge for an hour, and I was amazed and happy to see that it increased 38% in 60 mins. Well this tells me that the USB cable of my Note 2 is gone to heaven.
And oh, if you charge and use the device at the same time it will charge pretty fast even then too. I can confirm this when I first got the device, always was using it and charging, and I was surprised to even then how fast it was charging.
I (and many other users) have similar problems with Galaxy S3. I've made an app that shows the actual charging current: http://forum.xda-developers.com/showthread.php?t=2076078
I'm not sure if it works on the Note 2, but it is worth a try.
Please check if your device is charging at the optimal charging current (I think it is 2000mA for the Note 2 charger, instead of 1000mA as pointed in the SGS3 thread).
Is anyone else experiencing this problem or is it just how long it takes to charge this tab?
Plugged into the charger for an hour with the tablet off and it's only charged 15%. So it's going to take 6 and a half hours to fully charge?
Also the battery seems to die pretty quickly from just normal Web browsing. From 40 to 15% in an hr.
Battery life / charging / Simpsons tapped out lags / lots of stuttering with TouchWiz...
I want to be happy with this tab but it hasn't been easy
My battery life improves after a few charging cycles. I found Samsung charger is slow but not too bad. Mine charges about 30% an hour with tablet powered on but not in use. It goes a lot faster when using Nook HD charger, though both have 2.0A output.
My Note 3 charges so much faster that it's not even funny. And considering it's 10000 mAh...
Yep charges super slow. No idea why. Also drains super fast surfing web. People talk about getting 8 hours on this. Im lucky to get 4 but then again i like brightness high.
Use a launcher to improve Touchwiz stutter (funny that some folks complain about this stutter thing - on 10.5 have never experienced it even without a launcher).

Try to power down for a few minutes and then see if there was a difference after you powered on.
You can also check the task manager to see what is running on your system.

I always kill apps when I'm done with them. Guess I'll give rooting and removing all the Samsung apps a shot.
I got some decent battery life out of mine when I had it about 6-8 hours mixed use. Def noticed a big drop when surfing the web using white backgrounds. Charging also was painfully slow on mine I think around 3-4 hours from 0 to full charge for me when not in use.
It's been a staple of their latest tablets unfortunately. Just make sure you're using the stock cable/adapter as some of the aftermarkets don't have enough power. For example, I have a 10 foot cable but it only puts out one third the power then the included power cable using the same adapter.

Try using Galaxy Charging Current lite it helped me. I was using a Anker intelligent charger and it took forever to charge it. App showed current at 350-450mA. Used Samsungs and it showed 1800mA.
I have to agree, just received the tablet today albeit stressed out to the max because the fedex guy marked it as delivered when it wasn't to squeeze out extra minutes for a break (seriously?!?) I thought it got ripped off! So, back to the battery, I turned on the tab, beautiful this thing is by the way...and was at 62% out of the box. I began charging it using the included power cable and adapter, and 3 hours later I realized just how long this was taking to charge. Granted I was using it practically the whole time, I am hoping a higher amp charger will fix this for me.
Yup it took me 5.5 hours to charge fully. I'd be lucky if i get 5 hours of usage before the juice runs out.
8.4 inch charges fines here. 2.5 hours max, powered on or off.

Charge time isn’t particularly fast on any of the devices, but the 10.5-inch model in particular takes a while to make it to a full charge. The 10.5 will reach a 90% charge in just under 4 hours, but to make it to 97% takes another hour and the last 3% takes another 42 minutes on top of that. Usable charge time is competitive, but if you’re obsessive about always charging to 100% the 10.5-inch model does take a while to get there.

The charger that comes with the tab s is the same all new galaxy devices are shipping with. They do 5.3volts instead of just 5 volts. You will get a little quicker charge with the stock charger.
I get a legit 6-8 hours SOT mixed use

Slow charging NO charging
I hope this is okay to post here since it is a charging problem. I am on my third SM t-800. Mine stop charging all together! First one charged one time then stopped. Second on would not charge at all, It used up its factory 45% that it shipped with and nothing more. Third one was best by far and charged untill this moring and has stopped. Now, here are the details. I checked the cord by pluging into my note 3 on all of them. Infact my wifes Note 2. They charge fine. I don't have my ameter to check ampers but they clearly are delivering volts to the other devices. Now get this. I have a Bose external speaker that uses a mini usb. I plugged that one into the tablet and it is charging right now. Of note I had a concern that maybe some how the socket was bumped on the tab and somehow messed it up. But that is a long shot since the first two were used while only on a desk. So this third one has been supper "babied". I'm so frustrated right now.
BTW my first tab charged very slowly. 6-7 hours or so. Maybe more? I feel at this point the pins in the tab are not making contact. Any thoughts?

Just got of the horn w/ Samsung. Got issue taken care of. In short, the phone tech mentioned ampreage and I yanked the AC transformer off the wall and checked it. The factory transformer is 5.3v. 2.00ampers. In the dark last night i plugged into a "white" charger. An ipad charger I think, that is 5.2v. 2.4amp transformer. I switched the cord to the corect transformer and the tab is charging. Apparenty the chip in the tab was protecting the unit from over ampreage and it shut down charging. I know better than this and feel like a fool but thought I should let you all know what happened. This brings up a issue. Slow charging.... could the slowness be caused by a transformer with say 1.5 amps? Maybe the tab will let it charge but at a slow rate? Just a thought. Moral of the story for me? Plug in the tab in a lighted area, and into the correct charger.

Charging is a little slow, but the battery is large, so i accept that, but when it's charged 100% it lasts for ages. Faster charging shortens the life of the battery anyway. I could easily get 7- 8 hours constant surfing out of this tab. I've been on it now for over 2hrs surfing and it's used 13% . I always use auto brightness.
I get 6-8 hrs of mixed use, YouTube, surfing the Web and some movies with a little gaming. It takes me around 4 hrs to fully charge. Battery life is average. I'm using a 10.5 LTE.

Technically this is not true at all. It is heat that hurts batteries. You can charge as fast as you want as long as you keep it cold. That being said, Lithium Ion batteries will take a much faster charge rate and not cause heat. You could easily charge this battery in 2 hours, but the common chargers aren't that powerful.
