Battery life, how much will it last?

I just bought my excalibur about 1 hour ago and waiting for it to be sent to me.
Im buying it because my universal drained to much battery and was too big. I just checked the battery life on the excalibur just now and am very worried about he battery life on this as well.
I usually charge my phone every night.
So if i use this phone for say 4 hours of music with bluetooth headphones, 2 hours of wifi internet and bluetooth gps for 1 hour.
Will that last me through the day?

Yep should do and there are plenty of battery threads that will help you here
My device used to last 3-4 days with an Simplo 1550mAh extended life battery... "Past tence as i use my Tilt as everyday phone"

I have the standard 960mAh battery and need to charge every 1-2 days. Especially if I'm listening to music using Kinoma with an A2DP headset, browsing the web and so on, it can really drain the battery.
I normally keep a short USB cable in my bag that came from one of those 3G dongles, I'm often near a computer so it's easy to top up the charge if I need to. I charge short and often!

My battery will normally last a couple days depending on what I am doing with it. I do a lot of web browsing on my phone and it it will drain faster but it still will last a full day. I normally do not use the phone to play music so I am not sure how much that will effect the battery life.

i bought the 2200mah battery on ebay for 19 bucks yeah its bigger but the battery life was imaculant the stock battery if i used it most of the day then i would have to charge it all the time like say i go to work at 7 check my emails do some web surfing listen to music by 4 in the afternoon my battery life was at 1 bar and if your always on a constant go to places and the only charge you get is in the car but your not sitting there waiting for it to fully charge...here's one situation that really pissed me off i was 30 min away from home then suddenly my car dies (the altenator goes out) and from using my phone all day i tried to make calls but then the battery on the phone dies so i cant charge it or make any calls so i had to walkl to the nearest gas station to use their phone all cause the battery life of the phone sucked so the next day i ordered the 2200 mah battery and it lasted 2-3 days without charging

I was thinking about getting an extended battery as well. but then i though about the size. Is it worth it? If my Excalibur is going to be just as big as my Universal then i might as well keep my Universal!
Do you have your phone in your pocket? If so is it very comfitable and does it bulge out if you have tight jeans on?
I know what you mean with bad experiences with battery life!
My battery on my Universal is getting ready to die so much that if its completely flat it just wont charge with my car charger!
I was at work which involves alot of driving using my gps and Universal, my gps was going flat so i plugged that into my car. Mean while i didnt notice that my Universal was going flat as well. I couldnt do anything! So i just prayed that my Universal wouldnt go flat before my gps had enough charge to last a little while longer. But i was wrong. My Universal went flat and i was done for. My boss was very annoyed that he couldnt contact me and i got a big telling off!

If you go for extended your better of going for a Simplo Sendo etc rather than buying a cheap a*s battery off ebay.

simplo battery 2200 mAh
how much does it cost?

That looks rather nice actually. Blends in quite well with the back of the phone.
Where can i get a Simplo Sendo from. I presume ebay? (Im from New Zealand by the way)

I have no idea as i blagged by carrier out of 2 x 1550mAh have a look like you said on ebay but sure there will be other suppliers and as previous mentioned no point buyin cheap as Simplo are well renound for battery's.

Personally I prefer to carry an extra normal sized battery as I really like the slim design!
And as it´s my wife´s device (even if I´m the one installing an uninstalling ROM´s and apps ) she only use it for calls and sms so battery lasts a lot

Still haven't got my phone yet
Hope there wasn't a muck up at the post!

I just received the 1550mah simplo battery with cover from an ebay outfitter based in hk for a total of $15. Its the original oem part with an htc branded cover. Works great. The cover fits much better than the one for the 2200 batteres.

Atrix Mugen 4800Mah Review (56k/dail up death)

Please let me say, I failed english. Probably all that time I skipped english probably would have served me well....Had I attended, so be gentle on this guy. If this made you laugh, lol, "wow", that's neat, but if this helped you in anyway toss a thank post my way.
Hi it's been approximately 2 weeks since I received this battery. I can mostly say great things about this battery. Lets take a look at this monster, before I can say battery stats this, battery stats that.
I often Google how the extended batteries are "huge". I've SEEN extended batteries, none like Mugen though. Most of them are bigger, this thing really uses the word "Extended". First thoughts make me feel like this makes the phone x2 the original thickness. it feels hefty in the hand, and this makes for a constant reminder that the phone is in your pocket. I cant forget that this brick is in my pocket, but it makes it all that much more dramatic when it hits the concrete.....
I can say now having this battery installed on my phone is more than just extra juice, it makes for extra grip with this large backing. I'm sure a lot of people probably don't have extended batteries, so I'll just side-by-side a series of pictures so you can see.... how big it is.

Now that you see what it looks like, I'll give you my apparent opinion, its big... and there's more to that than just being big! (Or at least with "our" phones.)
This phone has one of the only biometric scanners that I know of, but it becomes somewhat a hassle with Motorola's choice battery location. Its not something I fret about, considering I don't use the finger scanner. I have tried it with this battery, it makes it awkward to use but not impossible.
Docks, another thing this phone was craftily shelved as. The phone with the @ss loads of docks, more than others, non with this battery will it fit... All of these normal Motorola docks are 'ment for the phone with the stock battery. When you want to dock the phone often, you pretty-much need to keep the stock battery and its back plate.
Cases as we know it are plenty and many far from few with this phone. I've seen more than a dozen cases with this phone. But I have yet to see a battery this "great", there is the problem. None of cases will fit with the Mugen battery! But this isn't a problem with me, I often battery pull from rom flashing anyways.
Lets get to the battery stats, and how it plays with a couple ROMS!... But 1 problem remains, I cannot get the android OS to condition the stats into it. So it majorically says 1% of the poor battery's life. With the extended battery, dont trust all of the OS stats, they dont depict full time ORRR accurate time.
CM7-Beta, Faux 1.3Ghz.
With my current setup on the OEM battery.
On Battery 9Hr:45Min
Voice calls 56% 3Hr:57Min
Phone Idle 18% 8Hr:57Min
Display: 16% 55Min
Mobi.mgeek.tunnybrowser 4% CPU/Total 42Min/9Min
Cell Standby 9Hr:42Min
CM7-Beta, Faux 1.3Ghz. (Mugen 4800Mah)
This setup like before but only the mugen battery changed here. The battery life off this battery makes it so I can shoot higher than 50+ hours, with my current use time. Calibration of the battery is not as easy as "Battery Calibration" when I used, it only shows 1% for most the time.... I could have sworn after this, I get better battery yet as I have tried this method.
Charge, turn off, pull battery, charge, pull battery, charge, untill the battery is surely full. Now from 4.206v down to 3.615v as we talk im currently trying to charge while on from 3.600~ maybe getting correct battery stats.
On Battery 59Hour~ (aprx, hard without OS giving correct stats.)
Voice Calls 44% 6Hr:43Min
Phone Idle 22% 22Hr:8Min
Display 20% 2Hr:33Min
Cell Standby 5% 1Day:1Hr:41Min
There was a screen shot for 57hours unplugged, but it continued till 59hours and shut off. It still does the 1% stats. from full battery, wipe stats, till here.
Later I want to try Froyo based roms, and see if I can break these records. (on froyo I got 6+hours of talk time, with bluetooth.) that's pretty good IMO. Mainly, just so I can see for myself.
Now for my conclusion....?
The phone is great on battery, if you let it. The battery gives more than double life! I like it, and all of it's size battery, and capacity! It just might be easier to give pros/cons.
Pros:
Lots of battery life, more than double
No annoying battery swapping
Size/Weight to those who like it
Cons:
Size/Weight to those who hate it.
Finger scanner hard to access
cases no longer fit it
I love this battery, and it's completely replaced all my oem batteries. No longer shall I battery swap. Besides how can you work a weekend or more and not use a charger.... Whilst usage like mine or better? You cant, only with Mugen's battery! You need one, more than need, you want one! I'll update with calibrated stats, vs max charge and drain to 1%-0%?

Battery
Reserved for OP
Ill compare stats vs OEM and this battery (Calibrated) But I'll try this with running netflix as a constant. Be patient, wont be long from now.

lol mother of god.. it's a bird.. it's a plane.. it's...

That thing is ****ing huge, lol.

This could come in handy for long road trips. Does it come with an external charger?

No but I'd suggest
http://www.ebay.com/itm/BH5X-Batter...376966?pt=PDA_Accessories&hash=item3a65952786
And for those who wanna know, ebay batteries are (from china) are garbage. I've owned alot of them, they lose capacity quickly and become buggy.
And if you dont believe me, try this...
http://www.ebay.com/itm/2x-Atrix-4G...408011?pt=PDA_Accessories&hash=item3368ab978b
I bet for less than 5 months of swapping batteries, and when their back plates break... Less capacity, and then become nothing more than mere paper weights, (should they not explode) cruddy batteries. Remember, cheap batteries off eBay are usually not rated for their "quoted" Mah! My 2800Mah battery from eBay lasted almost twice as long for about 1-2 weeks. Then no longer, about equal to original after a month. (And I purchased 4 of them) and 2 of them I had to return 2 of them because they DID NOT CHARGE. Now if you were planning eBay batteries, and wanted to make sure you had a weekend away from the charger, don't rely on eBay batteries from Chinese outfits making 90% profit off their less than 1$ production/labor costs.

Yer, that's about the life of my stock battery too, though for hiking trips etc imagine the uptime I'd get with an extended one (-:

This 4800mah seems to be the perfect battery for all the problems I was facing with the original motorola battery. But after seeing an youtube video and some images about it...whoooowww!!! This battery is really large. The Atrix becomes a really large and heavy phone.
Because of that, this is really not a good battery for daily use. I think it could be a good solution if you are going camping without electricity nearby for a whole weekend and then you need an extra battery. Otherwise i think it is really not a good solution.
My choice was this pack: http://www.ebay.co.uk/itm/220799408011?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
I'll keep using my original motorola battery and if needed I still have 2 x 3500 mah batteries (they also need special cover) plus a battery charger. They are smaller than 4800mha but even though larger than the original one. The price was really good and I'm totally satisfied with it.

Well when you see those battery stats, whats your talk time? It looked like you idled forever, and what rom/kernel/etc are you running. That would makes a big difference, Froyo(stock) vs alien faux 1.3 can differ battery greatly.

Talk time was several hours. Lots and lots of texting going on. About 45 mins of netflix. about three hours of the drag racing game. 10 mins or so of browsing. It looks like it was idle forever because thats over the course of 3 days.

hahahahahahahahahahahahhahaha thats huge

Will it fit in the car dock with this battery? just kidding - I think I know the answer to that!

Reference to the 3500mAh batteries, I bought one just like that from Deals Extreme, after a few charge cycles it gave me a consistent uptime of a bit less than the stock battery, for the price they are good spare batteries, but having to put a large back cover on for less performance than a stock battery really sucks for everyday life, I'd spend the extra to get another stock battery if you need one for everyday.
As for battery life, I'm running stock ROM, just rooted, search around this forum, lots of threads about getting 2-3x the uptime from a stock battery.

Near full of GSM coverage and just few hours of screen on ("Screen on" is near always OFF) is not what you have wrote us.
- A lot of texting with Screen off? You are God!
- 45min of watching video on netflix with Screen off? You are more than God!
- three hours of race game with Screen off?.......
Summary: (theorical) 3 hours of talk (much of GSM), 45 min videos (sound+screen), 3 hours of game (sound+screen), 1 hour (total) of texting over 3 days (GSM+display): 5 hours of "Screen ON" over 72 hours are more then you 3-4% if you try to sum the "ticks" of "Screen on".
Theorically every 10-12 hours the battery is automatically drained of about 10% even if the phone is in Airplane mode and with 200Mhz of clock (with SetCPU), so in 72 hours the battery should be less then 50% (I suppose 30%) even in Airplane mode.
You screenshot is fake.

[BATTERY REVIEW]Cameron Sino Tech 2200 mAh Lithium Ion "Fat Phone"

Just checking the post box and lo and behold my Cameron sino 2200 MAh battery had finally arrived from England.
It looks like the real deal but only testing will tell.
I purchased in from this Ebay shop.
They delivered it via Royal Postal Service and considering it is the Christmas season it took 14 days instead of the usual 8. Not bad.
The battery and shipping cost me around $22.00 US.
It's charging right now on my universal charger so I still have the use of my phone but I did take some initial photos of the difference in the case size, battery, etc, to post.
My initial response was...whoa! Big! It's exactly twice the depth of the OEM battery.
The back case of of a smoother plastic and not as "grippy" as the original. It's well made and fits perfectly.
The battery itself it a surprisingly tight fit. At first I thought I had gotten the wrong size but it finally popped into place and sits snug in the case.
In hand it feels different of course. Only with some use will I be able to really tell if it's a benefit or a detriment to have a case that size in hand. I have big hands so it might actually end up nice. Some swyping and other activities will tell and I will report of this when I do.
I did a test of the camera with the inset camera and flash holes and there are no blackout spots in the pictures, nor do they suffer in quality as a result of the case.
I had a theory that this case would be provide more bass by acting as a passive subwoofer cavity and indeed it does although I tested it with the standard battery installed. With less cavity space with the CSI battery installed it should fall somewhere in the middle.
One of the things I noticed is increased low end response was created with a sacrifice in overall volume which makes sense. Will report further once battery is charged and there is a little less cavity space inside the casing.
Below are some pics of the batteries, phone profile, etc.
I will follow up with usage test results once it's charged and in the phone.
Battery charged fully after a couple of hours as it was already pre-charged for a bit. On the phone and Battery Monitor base battery profile created. Will find out the true mAh once I deplete and recharge it once.
I hope it will be a day or two before I report in on this.
EDIT: Update
As I would have bloody well hoped, this battery does extend the life of the Wildfire S by quite a bit. Still trying hard to wear it down here by playing some games, coming up with a new tutorial, some recording of me playing guitar with 4 Track Pro, etc.
No solid stats yet but I will have after a drain and recharge or two.
Battery stays at a cool 25-26 degrees centigrade in operation and was cool to the touch while fast charging on the universal wall charger initially. I''ll provide charge while in use stats in short while.
EDIT:
11:10 pm and this thing is still charging. It's a lot of juice to squeeze in I guess. Waiting patiently and then I will post the charging profile screen shot from Battery Monitor.
EDIT:
12:00 pm and the battery is now showing full. Removed battery stats file and doing a complete drain. During charging while using the battery next jumped above 26.5 degrees centigrade. 10 degrees cooler than the stock battery.
EDIT:
2:00 pm and the battery is at 85 percent with moderate usage. Didn't get to sleep until 5:00 am and was up at 11:00 am checking mail etc.
I have to say that compared with the other WFS with the standard battery I REALLY like the feel of this double sized one in the hand. I find it easier for Swyping and general use. It just feels substantial and cups in the palm of your hand in a way that the shallow case doesn't.
EDIT:
The battery is still going strong. Used it heavily last night doing backups and playing Words With Friends online, tapatalk, gmail etc. for a long while. Had a mega text session with a cute girl.
Just after 3:30 PM on day two. Battery finally powered down after a heavy use phase for the last 10% for a total runtime on the first full charge of 40 hours.
Way cooler than the stock battery. Never got warm to the touch. Clocked in at 26.5 C at it's highest temp.
Apparently they even out and get even more capacity after a charge or two so if I get this up to 48 hours with moderate to heavy usage I'm thinking Phat is the new Thin! ;-)
FINAL UPDATE:
Battery charged over 7 hours while under a heavy load playing games.
All in all I've gotten used to the size, love the amount of power and longevity I get, it stays cool, and the price was great.
Next up... Ecell gold 2430 mAh standard sized lithium polymer review.
Coming soon.

Hehe.
Yah it's not the smallest but I'm liking how it feels in the hand even though it's no longer a Zoolander cell.
So far I've been running it hard since 5 pm or so yesterday. NANDROID backups, restores, lots of web time, some games, FB, doing a bunch of root stuff to fix GPS and figure out WiFi issues. Sitting here with another couple of estimated hours left on it. Trying to run it dry for a calibration or two and it's taking a while to say the least.
It's like the weekend pill Cialis...You could call this thing the weekend battery.
I'm going to order...cough cough...I JUST ordered the 2430 mAh Lithium Polymer from Ebay and I'm going to try it as well to see if I can get this kind of run time out of a standard sized battery.
Me <3 testing...

Hey bud. What was your usual 100 to 0% time on the stock battery?
Mine was usually just over 11hours.
With the CS battery 1day14hours (gets better after more cycles)
(note that leaving a phone on standby over night is going to drain less than a working day.)
I'm interested in knowing how you get on with that Gold 2430.
I dont expect it to beat the 2200mah CS but if it gives 25-50% more time over the stock battery with a standard formfactor then I'd be impressed.

Mine was in around 16 to 20 hours based on my usage.
I'll give you the stats on this one after it runs dry. Down 10% over the last 13 hours so far.

That's the test I'm more curious about. Anyway I thank you a lot for the review on the FAT battery. It's bigger so it should be better. As I already wrote on another thread I've had nice experiences with Cameron Sino batteries.
I'm curious about the Li-Polymer because the density and weight of the material are totally different. If that one approves I will buy one for sure.
Simply put I don't want to change the aesthetics of the phone to a Big Mac.

ROFL. Nice.
As I said I like the Big Mac. But I do prefer a Quarter Pounder to be honest.
I figure I will keep two battery stats files and swap from the low profile to the big mac depending on usage needs.
Going to the bar or something, it would be nice to have the smaller phone in my pocket so it doesn't look like I'm over-compensating.
I have read reviews on here where the 2430 clocks in around 1700. In my opinion for $20 that's a worthwhile upgrade to get nearly a third more batter life. Time and testing will tell though.
It shipped today. Hope to get it before Xmas.

Good luck with the shipping time and with the batteries too.
If the Li-Polymer Gold battery only has about 1700mAH then it is pretty false advertising. My feedback would be pretty negative on eBay.
Sellers shouldn't be so greedy and announce values that are way above reality.
Anyway if 15.50€ gets me about 30-35% battery increase then I will probably buy one.
An original battery costs the double...
I will wait for your review before I decide because I really don't like ordering so near Christmas...
Thanks for your help mate.

No Problem. Up to 37 hours with moderate to heavy usage now.
Final update. 40 hours on first charge.

No Problem. Up to 37 hours with moderate to heavy usage now.
Final update. 40 hours on first charge.

This means that on the 3rd or 4th complete charge cycles you will probably get a few more hours. Just follow the battery maker's instructions and I guess that 45 hours of moderate usage will be possible. That's quite an achievement!
Even if it's a Big Mac, for work purposes that wouldn't be a problem.

I'm charging my battery every day...This is too big to my little WFS

I concur...

Awesome post, might get one of the 2430mah ones if it's moderately better than this one.

Will let you know when I test it. This one finally averaged out at2263 mAh. As advertised.

Cameron Sino still takes their business very seriously. That's great!

OP, can you come back after a few weeks using this battery, and do a 2nd review to see how it's lasting?
I only ask because I tried a similar 3500mah extended battery, which was amazing for the first few days, but after a week or two it started losing it's charge realy quickly.
40 hours use from a single charge seems awesome, but I don't wanna go spending on another battery until it's withstood the test of time

No problem. I'll put it in my Calendar.

Awesome, can't wait for the results

Nice testing,we shall se if we have new battery champ for our nice wfs

3,800 mAh Extended Battery Review! *Video* *Pictures* *Screenshots* vs stock!

If you have bought this battery, and have experiences, good or bad, and want to share them, let me know!
No longer providing daily updates, but will post how the official extended battery compares in a few days!
If you guys would like me to either carry on testing this battery out, carry out tests on batteries I have (stock, extended, 1950 ebay), or purchase others and test them I'm more than happy to (providing cost isn't too high!) Just let me know!
Scroll down for a 100% to flat Vs stock!
Check out tuner520's findings here, here, here and here!
Hey guys,
So I took the plunge and bought one of these 3,800 mAh extended battery and covers from ebay, they finally turned up today and I am very impressed! I'm not going to try and say the back isnt ugly, but it is far easier to look at than I expected! I was expecting a massive ugly lump, and while it is fairly ugly, it isn't that big for the bump in battery life you'll be getting! The cover follows the curvature of the phone to start with, then flattens out over the top, unfortunately, it seems the designer got bored when it came to the end, and just made a square edge!
I have yet to put the battery through it's paces but will push it hard over the next few days and get back to you with the results!
Video Review!

More pictures in this gallery!
Day 1
So Its 8:30 pm here in the UK, been unplugged since 8 am, fairly heavy usage, still got 22% left. Will update with screenshots later tonight!
Day one (first full cycle) Screenshots!!! (the gap is where I made a clockwork backup) At least an hour of GTA played, and 3g was constantly on.
Day 2
Very light usage today due to having exams, so been revising all day (sitting an exam part way through). I am going to pop the battery out and do some reviews of some new cases and the official extended battery I just received, then pop the 3,800 back in and carry on into day 3!
Day 3
So I took out the battery to do some reviews last night, then put it back in, and carried on! Light usage to start with, then medium usage towards the end of the day! (streaming music, web browsing) This battery just will not go flat with this usage!!! Very impressed, it's still only on it's second cycle!
Time for some quick maths if we take day 2 and day 3, add the total time together ( 12h 27m 23s +1d 1h 44m 55s = 137,538 seconds = 38.205 hours (I think!)) and take it as 50% battery used, we can calculate that the battery should last 76.41 hours, or 3.18375 days, which is pretty impressive!
Hope you guys are finding this useful, I'll update again tomorrow!
Day 4
Okay, so I used it a bit more today, and as a result it's now flat! I'm going to charge it up overnight, and tomorrow I will do a 100% to flat test streaming youtube videos, and compare against the stock battery to see how this beast does!
Day 5 - 100% to flat vs stock!
Currently running what I shall call the nyan cat test. Screen brightness on full, bluetooth on, NFC on, portable hotspot on, running on 3g, left in the same spot, playing the 10 hour nyan cat video from youtube.
Done the 3,800 mAh battery, impressive results! Just testing the stock battery then I will post up screenshots of how long they lasted! If there is enough demand for it I can also carry out this test with the official extended battery, as well as the 1,900 mAh batteries I have from eBay.
Results
Okay, so first up is the stock 1750 mAh original battery!
And now the 3,800 mAh extended battery!
So, the results speak for themselves. 3 hours extra screen on time, and the battery is still only on its third cycle!
Update: I tried to make it look better by covering it in white carbon fibre effect vinyl, but due to the excessive curves around the camera (and my somewhat lacking skills), it did not end well!

so review it and tell us if it really doubles batterylife hope so otherwise it is really damn ugly
but for that price not going to argue xD

Will do! Gunna push it hard for a few days and see what kind of life I can get out of it!

Damn! Why didnt you get the big one?

That is one big battery!
How much weight did that thing add, counting the battery and the backpiece?

I'd say the battery and case weigh around twice the originals, so it's a noticeable amount of weight extra, but not too much!

so your NFC now is not working right?

Nope, NFC does not work with this battery.

Wow....would you like a side of phone with your battery!
But then again, I had a Nokia 9000i Communicator...so that is still an ultra slim phone!

So are you actually seeing double battery life with this? I recall reading a while back about some 3rd party battery tests and they were only performing at about 50-60% of their rated capacity, while OEM's performed at 95-98%. The back case is hideous... I really hope someone comes out with something in between the lackluster 2100 mah ext battery and the 1850 OEM battery.
*Edit*
Saw this was for the GSM version... Whoops!

can't wait to see some battery life screen shots with this!

Updated the OP with day one screenshots!

Has anyone found a deal for a battery of this size compatible with the LTE model?
(Preferably not the Seidio version, as it retails for near $70.)

13 hours from full to empty with 4 hours and 20 minutes screen on time with a big 3800mah battery, i get 20 hours from full to empty with 4,5 hours screen on time with my stock 1750mah battery.
I know its the first cycle but i really hope it improves alot
Sent from my Galaxy Nexus using xda premium

I've had all types of extended batteries for my Evo 4g and my Evo 3D ranging from the cheapo Chinabay to the $75 Seidio 4000mah batteries. Seidio has the closest mah rate as advertised and I once was able to get 120hours of average use out of the Seidio 4000mah battery. The Fleabay extended batteries are only "slightly" better than OEM and it adds the pregnant look to your phone.
Now that I am on the Galaxy Nexus and have loved to use Google Wallet, I am not so keen to jump to use extended batteries that do not support NFC. If Seidio is able to make an extended battery that has the NFC antenna, I will buy it in a heart beat.

Gah.. I'm at four hours screen-on time with my stock battery

Yeah looking at your screen shot, I'd estimate it's about a 2200-2500 mah at best.
A stock battery can almost hit 4 hours, and that ones got maybe 4.5 hour.
That's like what, a 60% effective mah over the rated?

I should have mentioned this, I clocked around an hour of GTA use through the day, plenty of web browsing and some video, I would struggle to get through half the time this battery lasted with my stock, and that was it's first cycle!

+1 for 3800mah batt for GSM and recommend it to heavy/busy users.
Battery Monitor says batt life is
13h55m with my heavy usage
13days4hrs Standby
I measured the weight of the batteries and 3800mah is 68.65grams versus stock at 37.75g
BTW, my phone (SC-04D Docomo G.Nexus) is same as the US GSM type. The GPU is overclocked to 384mhz, processor overclocked to 1.42Ghz and its tweaked from kernel to baseband.
Also, I noticed is that this battery has a working internal temp sensor unlike my X10's mugen 3600mah. I don't use NFC but can put the stock batt back in for that moment... it only takes seconds for the Nexus to boot up anyways.
If you need/want extra batt power, I highly recommend this battery. I've used these fat type batteries for 2 phones now and love them both.

2100mAh Extended Battery: 2-Day Impressions [LTE]

So I finally decided to pick one of these up before the sale ends (yes, they are still half off at Verizon corporate stores). The stock battery provided "acceptable" battery life, but I was really apprehensive about losing the little hump on the back of the phone (and $25) for only ~13% additional battery.
So, in short: it's a good buy. Obviously it won't DOUBLE YOUR BATTERY LIFE or anything, but it kicks the phone up from right at the "acceptable battery life" line to the "good battery life" area.
When I first got the battery, I allowed it to charge fully before using it, and the first night of use was comparable to the stock battery, maybe a bit better. After letting it charge overnight, I got much better battery life the second day. I decided to cycle it a second time.
The first ~12% of the battery life on this cycle was used flashing a kernel and then recovering when that kernel created a multitude of issues. In short, I spent a good 20 minutes wiping dalvik, resetting app Cache/Data, fixing permissions, re-installing Nova, etc. It was a mess, and for this reason my battery stats neglect to show a good 15% of the beginning of the cycle, for which I apologize, but if anything this just makes my recorded runtime that much more impressive to me.
I historically get about 2.5 to 3.0 hours TOPS on my stock battery.

Disclaimer: I was on wifi 99% of the time, but was resetting my router when I took the screenshot, hence the 3G indicator.
On the second cycle with my extended battery, I got a pretty good chunk longer:
And again, that's with the first ~20 minutes of flashing/installing/chaos not recorded.
For what it's worth, I also got rock solid standby on the extended battery. When I went to bed, I consciously noted the battery at 42%. When I woke up 5 hours later (it sucked ok), the battery had only dropped to 41%. Seriously.
This is totally anecdotal and non-scientific of course, but based on my results (so far) and having heard similar reports from other members here, I would not be surprised to learn that either the stock battery is of poor quality/chemistry, or the extended battery is of higher quality. A 13% increase in capacity, by all means, should not provide such a drastic improvement in performance, but I'm seeing a 19% increase in screen-on time alone.
So, I don't claim to have evidence that there's more than a numeric capacity increase to the extended battery, but the real-world results are certainly pleasing, so I don't really care!
PS: I do miss the hump, but the extended battery/cover gives the phone a nice feel for its own merits

Ya it's not a huge increase but I could tell the difference; definitely worth $25.

I left the house with full charge yesterday, the first day with my extended battery. I noticed I was down to 90% rather quick, checked for wakelocks and had none. As the day went on my battery life seemed to drain as it had with the stock battery. The extended battery didnt really "kick in" until I got down to say 10%. At this point it took longer than usual to drop down in percentage. I checked my battery stats @ 4% and again found no wakelocks, my screen on time was a bit under 2 hours (like stock battery), I really didnt notice the extended battery at all. I figured this would give me that bump to take my Nexus through the whole work period without having to do a quick charge in-between jobs (DirecTV Installer). I hope I get better life out of it today, like OP did on his second day!

These batteries take a couple charge cycles to get to full capacity. Give it a couple days and you will start to notice a difference. 1850mah to 2100mah is not that big of a jump though. It's not gonna get you a huge increase other than maybe about 10%-12% longer. I bought a desktop cradle that will charge the phone(it fits with the extended battery with the standard backplate) & has a slot to charge a spare battery. It's pretty handy because I can charge the phone and the stock battery at the same time and can easily change batteries if needed. I got the cradle on Ebay for $20. It shipped from Hong Kong, but surprisingly only took about a week. I bought it on the 2/17 and it arrived on 2/25(seller shipped it on the 20th so not too bad). Shipping was free. Here's a link: http://tinyw.in/RpFR
Here's another 1 from same seller. Different title, but the cradle looks exactly the same: http://tinyw.in/E6PN
Btw cordell12, I don't know if you remember me from the Evo 3D forums, but glad to see you over here. How long have you had the Gnex?

After a couple of charges I've noticed that the device does have a nice increase in battery life. Nothing to write home about, but that extra 10-15% is nice to have especially since I got it at the Verizon corporate store for the $25 sale. If nothing else though, the added weight (very minimal) and feel of the backplate complete this phone for me. Feels so much better in my hand.

So you're getting almost 4 hours of screen on time? I think I can eek out 2 hours and make a full day with my extended battery. I'm thinking I got a junk one if I can't get at least 3 hours of screen on time.
Think if I get another battery, it'll work better than this one? Previously, I only used the stock battery, and that thing lasted me a good amount of time... and oddly enough, it felt like it lasted longer than this extended battery. I've been using it for over a month now, and I don't have many things syncing to my phone so it shouldn't be draining it as much.
I think I'm going to buy another battery, and if it doesn't work, then whatever I'll just have another extended battery.. Right?
I wish I could give you a good idea on what my battery life is like, but I feel like I get about 13 hours with 2:15 screen on time and that's with maybe.. 30 minutes of a light game and the rest of the time is texting/reading/surfing the web. I use Wi-Fi at least 70% of the time as well.
Right now, I'm at 10 hours and 40 minutes with screen on time at 25 minutes. The battery percent is 66. I feel as though that's pretty good, but to be honest with you, if I start using the phone or getting texts or anything, it'll drop extremely quick.

I am not sure why this phone didn't worth this 2100 ma battery in the first place.
The increase in weight or thickness are so small that it's crazy that out was shipped without the bigger battery.....definitely worth the 25$

Not quite. The battery (chemically) works best on the first charge and gets incrementally worse with each charge, exacerbated by exposure to high temperature. The phone, however, needs several large charge cycles before it calibrates to the battery. This is why the other poster didn't seem to notice a difference until he got to 10%. That's poor calibration. Eventually, the curve will straighten out and he'll see more accuracy. The battery will still cut out at the same voltage it did on Day 1, but he'll have a better idea of when the cutoff will come.

This is true for li-ion batteries AFTER the battery has stabilized. The battery needs to be reach a chemical balance in order to provide full charge/discharge efficiency. This optimum chemical balance is reached after first 3 to 5 charging cycles (even more for the cheap ones), depending on the exact chemical components used to fabricate it.
