dont buy the extended battery

i recently bought a extended battery with cover off of the official VZW online store. the battery worked great for about a day until the battery life ran out, then i tried to charge it and now it just started randomly shutting off on me even when the phone said i had about 60% battery remaining. so i left it in the charger over night and now it wont even turn on at all until i put in the regular battery. so i ordered a new one and you know what happened? the exact same problem occured with this battery to. it worked fine for a day, then it ran out of juice and completely stopped working.
so here is my warning to all of you. DO NOT BUY THE EXTENDED BATTERY. it is complete garbage and does not work at all. dont waste your time or money on it because you will for sure have the same problems i did. i am now stuck with 2 non working extended batterys that i need to send back to verizon to get my money back.

I was having crazy issues with my batter acouple nights ago. I never let my phone completely die but it happened this sat. I put it onthe charger then when I tried to turn the phone on the battery meter went from 0% to 5% to 60% then I unplugged it and tried turning it on to no luck... thereafter I put it on the charger and waited for it to get to about 15% and turned it on while still plugged into the wall and it started up. I let the battery charge full and the phone began working like normal.
I am on leaked 2.2, with rubix rom and o/c'd 1.15 and on stock battery

I have 2 stock batteries that I swap daily. If you let the phone die completely you can't turn it back on until you've charged the battery to at least 5%. Sometimes when I swap a battery from a fully charged to one that's about 15% to recharge, it says it's at 60%. Not sure why, but it sounds like the phone's software looks at the readings and says to itself, "there's no way I can go from 100% to 15% when I shut down and rebooted." I'm sure it's just the software being stupid.

I've had the extended battery since I bought the phone about a month ago, never had a single problem with it and my battery life is great...

I bought the extended battery when they became available, and have not had a problem with it. Knock wood

Love my extended battery. No issues here.

No issues with my extended battery either. In fact, I regularly get 30 - 36 hours out of it!!

Extended here too, no problems whatsoever since it was released. The issue I have is the motorola cases not fitting.
Had I known this, I would have bought the Siedo extended battery instead.

I just bought 1 of the hard cases from verizon and it's allllmmost perfect. No problems whatsoever except for that the 1 spot above the charging port will not stay snapped. i got my extended battery last night. I let it charge for 12 hours for the first time and I hope that helps it. I kind of believe that that is some peoples problem. they don't let it charge long enough the first time. I let it charge 10 to 12 hours and then let it die all the way the first 2 or 3 charge cycles. Then I usually plug it in once It gets down to 15 percent and every 10 or so charge cycles I let it die completely. I can't wait for the seidio 2800 mah battery. Is there any news on a release date? I had the 3500mah battery for the incredible and it was spectacular. I use the phone so much that the standard battery only lasts 3-5hrs but the seidio innocell lasted 1.5 days. A huggggeeee upgrade. But I couldn't find a reasonible case afterwards so I kinda put my silicone case on and traced around the new battery cover with a boxcutter to make it fit. Afterwards I melted the edges with a lighter to smooth them and prevent splitting. The DInc seidio extended case doesn't cover the bat door anyway. Not to mention it doesn't even cover half the edges. I sure hope they design a bettr case for the DX cuz I love their batteries are the best

Are you using the Moto charger?

I had similar problems with my first extended battery for the Droid X. However Verizon replaced it, and there has been no problem since.
As for incompatibility with cases, I use the snap on clear case from Verizon. Had problems with it not wanting to stay snapped together. After modifications to the case failed to correct the issue, I removed the battery cover completely. No issues anymore.
Plus since I use the clear case, I have a nice nerdy view from the back.

I received my Extended Battery two days ago. I love it! It holds significantly more power. And I can still use my Body Glove Droid X cover with the Extended Battery and included battery cover.
Anyway... I rate my extended battery experience as 10 out of 10.

I cant say I noticed to much of an increase but i'm back and forth with modding and o/c so I know lots of that goes into play with battery times.. right now i'm on an UV and I can easily go into a 2nd work day without needing a charge.

Yes...extended battery didn't make a bit of difference...it made a HUGE difference.
It is barely noticeable in size...fits in the multi-media dock, no probelm with my hybrid TPU case...and lasts quite a bit longer.
Or maybe I should say...gets me through to where if I did run out of juice...I'm at home with a charger. Either way...I'm good from 6am to 6pm at least. (i dont call anyone btw). Just massive amounts of texting and web.

I have had mine for almost 2 months and it works great. I deffinitely notice a difference from the stock battery. Would by again if I had to do it all over.

It's good to post your experience, however don't you think a sample of one device and two batteries doesn't qualify as a crappy accessory? I've been running an extended battery since it came out with great results. As a matter of fact a week ago I tried to go back to the standard battery just to make sure the improvement wasn't in my head and the difference was at least 3 hours.
So assuming you aren't frightened at the prospect of returning a battery if it doesn't work for you, go ahead and get one. For a very modest bump in weight it adds a lot of life.

Don't buy the extended battery
I also bought the extended battery from Verizon. It works fine except for a small problem. The built-in battery monitor some times complains that I have installed a non-compatible battery or something like that and suggests that I replace it with the original. A question mark "?" shows up in the status bar and the battery level is not reported correctly.
I picked up "Juice Defender" and paid for the pro model. It says that in last 48 hours It has multiplied battery life by X1.73. I also downloaded an app called "battery Status" which shows the percentage of battery left. Lots of nice options for display.
So what did I do with my original battery? Hmmm I noticed that it is fairly thin so I stuck it in my wallet. Since the ram is non-destructive, I can change the battery when it gets low.
All in all I am very happy with the "Extended Battery" I got from Verizon.

Sieidio Battery 1750mAh Extended Battery Review

I purchased the Sieidio Battery 1750mAh on Amazon about a month ago. This battery is not worth the money at all. If you want an extra battery then I suggest buying an OEM battery.
I might be wrong but I think this battery actually goes down faster than the one that came with the phone. My biggest problem with this battery is that it does not fit properly in the phone. It can just be set down or place in my pocket and that is enough to make the phone.
DON'T wast you money on this battery

I don't even understand your review, but I guess I do understand you are being negative.
But this battery works way better than the stock battery that came with my EVO. It ****s on the stock battery. Diarrhea.
Maybe it's just because I bought it for $50 from Best Buy. What a bargain!

Sounds like too much for a 1750 battery. I'd rather just go all out and get the 3500

I got two 1800mAh batteries for about $30, and experienced the same thing. After awhile though, I realized that you have to do a few things to get better battery life.
1) Charge the battery to full while the phone is on.
2) Unplug and plug back in to verify that the phone is fully charged (green led)
3) Turn the phone off
4) Unplug, plug in, and wait for a green led
5) Repeat that 5-10 times
6) Then while still plugged in, reboot into Recovery and wipe the battery stats via the advanced menu.
7) Reboot, and use your phone as you normally would.
This may sound like alot, but it really only take about 5 mins. Even after wipe, it will still take about 5 full discharges to reap the better battery life. Hope this helps!

I think its just luck of the draw on aftermarket batteries (the cheap ones at least)
I have heard good and bad on ALL of them.
I got the Chichitec/htcexpress 1800 batteries with charger. Came in the other day and I couldn't be happier. 14 hours on initial charge, that's unheard of for me. On my stock battery I had to keep the phone plugged in most of the day at work just to still have juice by the time I got home. And supposedly these things start acting even better after a few charge cycles.
(Fits with stock battery door too)
But for every person that has a good experience with any of these companies, there's someone else with a horror story.

Could have told you that before you bought it, ratings by aftermarket reputable companies are close and never accurate...if they rate it at 1750, it's probably 1500-1650... The stock is 1500 so yes you wasted your money. Now on the other hand, the 3500 is the best investment anyone could ever make....

It's been proven long ago seidio over rates their batteries. The "1750" is actually just under 1500, so less capacity then the stock battery.
Sent from my PC36100 using XDA Premium App

just terribad in my opinion, gonna stick to my seidio 3500. rather have the size and life than a small size and a measly bump from the 1750mah battery

They rated it less than a 1500 stock battery.

Key with extended batteries is that you actually have to charge them longer than your phone indicates.
Example: I phone said it was fully charged at 3:26am in the morning. Yet it continue to charge until at least 6:45am before it was constant. Granted I am using an SBC kernel but even without, you need to let it charge the night. Don't let the green light fool you. It takes a few extra hours to charge even if the led light is green!
You should just about fully drain your battery and then let it charge overnight. If you aren't on an SBC kernel you may actually want to charge your phone while it's off so that the battery dictates the charge.
You should also wipe your battery stats once the phone is fully charged.
Try that and see if it works for you. I know that I was getting great battery life even on the stock battery. I play "Word With friends" (at least 15 matches running) a lot (at least 15 matches running concurrently) and this game actually drains battery. I still got through the day fine though I also carry a Touch Pro 2 and having the batteries that are the same size allows me to swap when needed.
I have the 2650mah one from sprint and my 3500mah seidio coming in the mail tomorrow. I'll probably write a review for it later. Note, On my 2650mah, it's already on its 12th hour and I was was playing WWF, surfing the web, made several calls and it's still at 77%. I will leave it off the charger tonight and see how it fairs tomorrow.
Good Luck!

I have tested these and if they do last longer then stock, it is only like maybe 20 mins. I have an external charger as well as running the SBC kernel to get a complete charge. I have the sprint 2600 battery as well and love it. Not many cases for it but I have modified a sedio rugged and ballistic to work with it. I let my wife use it for a few days in her evo and had to fight to get it back from her.

[Q] Is an extended battery / second battery a must?

So, my OG Droid was acting up and my upgrade wasn't due until late july so I decided to purchase a Droid X.
While, I don't have the phone yet, and it is used I was debating whether or not a second battery is necessary as I will have a car charger from my original droid. But, at the same time I have had a second battery with most of my phones for years. But, then again I will most likely be replacing this phone by Sept/Oct the absolute latest.

You might be able to get by on just one battery. It seems the DroidX has one of the best battery lives for Android phones. If you do buy another battery, I would suggest the extended battery. It adds only 1mm to the back of the phone and it gave me around 4-5 hours more battery life than the standard battery. Then you can always have the standard battery on backup if you need some extra juice at the end of the day.

thanks for the tip

On Rubix Focused I can get 24 hours of battery life with heavy use! I have been thinking of getting an extended battery though. It would just be convenient

I have an extended battery and carry the standard battery that came with the DX in my car just in case i ever need to swap..no biggie, convenient.

Hey, I used the BH6X from Motorola and gave me superb life. I got more that 20 hrs (using juice defender) from it. Im now reviewing the 3800mAh that I got off eBay on the X2 forums, you're welcomed to come by since this battery is for both x's. I didnt want to start a whole new thread here in the X forums.
http://forum.xda-developers.com/showthread.php?p=17751410#post17751410

it really depends how heavily your using your phone and what for
I have 2 Motorola BH5X Standard 1500mAh Batteries I keep on me for backup at all times, which, ever since my sister-in-laws wedding and a trip to disneyland has become the standard for me.
Turns out taking a butt load of pictures and helping my wife manage the people at a wedding required a total of 3 batteries for my phone
Meanwhile, taking a lots of pix at Disneyland with no readily available outlets for my external charger also made 3 batteries the perfect number, especially after recording those late night light shows.
On a regular day though I can stretch out a single battery if I have an outlet for charging nearby or 2 batteries without a charger.
and yeah, I don't restrict data either so that does a number on my charge.

I get around 30 hours on the standard battery but I work from home, doesn't get two hours of streaming use on the way to and from work anymore. When I was driving two hours I would charge it every afternoon on the way home depending on the previous nights use. I also picked up a xoom so I use the phone a lot less now.

I am LUCKY to get 7 hours... I had to get a 2nd battery!

I ended up buying a second battery from Amazon for like 5 dollars and a cheap charger for the battery. Anytime I know I'm going to be out for awhile I take the extra battery. It has saved me a bunch of times.

If you're playing games or streaming movies a lot then I would def get one. With moderate use, I get at least 12 hours on mine

I would advice to replace a factory battery with an extended battery.
This one for instance is 3600mAh Extended Battery by Mugen, at least twice the capacity compared to factory battery. Reliable brand as well.
http://www.mugen-power-batteries.co...y-for-motorola-droid-x-with-battery-door.html

I would recommend one if you use your x constantly more than 4 hours in a single use.

HTC Extended battery good results.. very little bulk

I was on the edge for quite some time trying to figure out if I wanted to buy one or not.
Im glad I did. On an average WORK day Ill rape the battery and itll be lucky to last the duration without charge. Average of 60-90% OUT of signal during this time. (no wifi at work). Today Is my first day on a full charge with the extended battery and Im sitting at 78% left with the same day to use use and have just over an hour left. To be able to stay AWAY from the charger today has seriously been amazing. On my D1 with extended batt I was able to do the same thing, normal battery not hardly.
For regular battery off work days I can easily go 18hrs on a charge without fear. Im looking forward to my few days off and seeing what I can squeeze out of this extended battery.
For those thinking about going extended just do it, you definitely will not be sorry at all. The size added to the back is seriously so small and it even fits nicer in the hands. In my jeans pocket its not even noticeable either.

Agreed. Use CM7 and juicedefender and you'll get 40+ hours out of it.

Battery Life Doesn't Matter

(Personal opinion here, of course.)
I don't care about battery life. The battery on the Galaxy Nexus is removable. When my phone is dead, I swap out my battery for another one. Two batteries gets me through ANY day, regardless of usage patterns. Batteries are small and fit in men's and women's pockets easily. They fit in glove boxes, desk drawers, etc. They're portable, lightweight, compact, etc. You can take them almost anywhere.
I purchased the Samsung battery charger kit and haven't looked back. Instead of charging my phone and feeling tethered to my charger all day, I use my phone however I want and swap batteries in/out as I need to, and I only charge my phone overnight while sleeping now. The rest of the time, I only charge my batteries through the charging kit.
All these threads on battery calibration, battery life, etc. just seem unwarranted to me. I'm used to toting a charger around with me, so now I just bring my battery kit (usually it sits in my car, not needed) and if my battery dies, I swap in a fresh one and charge the spare with the kit. This way, I can have my phone on me all the time without worry. If I have no nearby electric outlet I can still take along the extra battery and charge both batteries later. I actually have 3 batteries, if I need them (I can't imagine ever using all 3 in a day).
I don't even use the extended battery. Why fatten up my phone, even if only by a little, if I don't need to do so?
This is food for thought, that's all. Does anyone else just use spare batteries and no longer worry (or even obsess, as I used to do with my Thunderbolt) over squeezing out every drop of battery life? To me, life is easier and better this way.
There's a name for the feeling of not being tethered to your charger all day. I call it freedom. It's awesome.

I see where you are coming from.. What do you think of the battery cover? Is it difficult to work with when swapping batteries and will it last with such frequent use? How do you make sure that your spare battery is always ready (I guess you must be in the habit of always putting it on a charger)?

The battery cover is easy to remove. I ordered two spares when I ordered my battery kit (door covers are only $3 each) in case they wear out over time, which I doubt will happen. Many days I don't even swap batteries, as my phone typically lasts 10-12 hours on the regular battery anyway. I do charge my phone in the car (why not? my phone would just sit there otherwise) which is ~30-45 minutes a day, enough for an extra 20% charge mid-day which helps my battery hit the 10+ hour mark. And if it doesn't, I just swap for a new battery.
The spare is always ready because I always keep it in the charger kit so I can grab it when I'm in need. The kit has a light which turns green when the spare battery is charged to 100%. The light is red otherwise. It's quite handy.
At night I plug in both my phone and the charger kit using the Y cable charger that comes with the kit (allows 2 devices to charge simultaneously on one charger). In the morning, I have my phone and spare, both ready to go.
May I also say, I've impressed a few of my iPhone-using friends with my spare charger kit. They always say "I wish I could do that, but I don't have a removable battery." I lol every time (silently to myself...)

I completely agree. That and who is really not near a charger ever all day? Maybe a few but hey that's what changeable batteries is for.
I see nothing wrong with improving what we have with calibration and optimization though...

Lol sounds like you are super jaded from using a thunderbolt.
IMHO your logic is flawed. Why not get good battery life on one or two batteries rather than mediocre battery life on two batteries.
You shouldn't have to carry around two batts just to get usability out of our device. Two batteries is for when you demand extra from your device.
Like when I went to New York I carried two batteries for my BB9700. Not because it was a battery hog but because I was GPSing and texting all day and didn't want to be stranded with a dead battery. I ended up using both batteries several times skipping charging both of them one night.

edit: I get great battery life on this phone btw. I love it and am very happy with its performance.

I do the same thing. Have the extra battery with wall charger and just throw the spare in my pocket if I go anywhere. Like the OP stated I would much rather swap out the battery (if/when needed) and be able to use my phone like I want than worry about trying to conserve it all day.
I haven't had any problems with the battery cover and even if it did I can buy a new one from VZW for $3.25 with my discount ($4.99 retail) so it is a nonissue.
I honestly don't know why so few people do this. And I very rarely even end up using the spare battery, I just like knowing I have it if needed.

Agreed. I read that stuff to be informed, but no longer out of a crazy desire to extend my battery life because I can't live without doing otherwise. It's a nice change.
Again, I'm not saying anyone else has to or should do this. But it makes so much sense to me, and I like to share what works for me to help others who are looking for other options regarding battery life.

I'm a realistic type of guy. What I want from my phone and what I get from my phone are two different things. To believe they are the same is literally delusional, by definition. To complain about X Y or Z company not providing me with what I want is also a bit irrational if I know that, given today's technology's limitations, what I want might be asking a bit too much. We must work with what we have. I have spare batteries. I use them, liberally if I need to, and I don't mind doing so.
I don't expect a 4G phone to last all day while I play WWF, browse the web, text constantly, check and compose emails, take photos, transfer data, and make phone calls. To get 3-4 hours of screen on time on one battery is great (to me).
I think carrying an extra battery is being more responsible on my end for my own admitted usage of the phone, rather than complaining that the battery life "sucks" or hacking my phone to get an extra 20% battery life (although I'm not against this at all - it's just more work overall). Instead of blaming Verizon, Google, and/or Samsung, I'm taking ownership of the fact that I use my phone quite a lot, and I'm fine with carrying an extra battery or two. Instead of blaming others for the battery life of my own phone, I take responsibility for it and I provide my own solution. If anything, I'm speaking of personal responsibility. And in said responsibility I've found freedom from the dreaded phone charger. Again, it's a nice freedom to have.

I agree completely with the OP. A second OEM battery and quality wall dock charger are my second accessory purchase with any of my smart phones. The first being a good case.

Having a 2nd or 3rd (or 4th!) battery and/or a charger around shouldn't be a requirement for using your device throughout the day. Sure if you use your phone hard then you're going to be used to having a charger nearby, but it shouldn't be a req if you're a normal user.
I don't think its unreasonable to expect a normal (12 hours) days use out of a device. FWIW most people are getting that (especially GSM users), and I don't think the battery issues are as widespread as people seem to think. There are "omg batterylife" threads in every new device forum.

I often go a full day without seeing a charger. Sure I could carry one around and hunt for outlets throughout the day, but I don't think that should be a concern. Just want the phone to be reliable.

For what it's worth, I bought an external charger a couple phones back. Just plug in via USB to the phone if it's running low. Really useful when I'm on the train, for example, and I tether wifi for my Xoom. Gets me through the day in a pinch and I don't have to buy a new one with every phone (though I might buy a larger one now given the Galaxy Nexus' bigger battery).
Also, I usually plug the phone in while at my desk and always charge overnight. But I use the hell out of my phone

I have to agree with Martonikaj I'm afraid. Its a phone, just because you CAN swap out the batteries doesn't mean you should HAVE to to get reasonable usage life.

I disagree with the OP for having 2nd, 3rd batteries in order to use it properly based on user usage pattern.
First, define your usage pattern then try to optimize the battery to support that.
My usage pattern requires to have at least 3 and a half our screen time, and charge the phone once every two days, before I went to sleep (or during the night).
And this phone battery can do that without any problem ...
So, I don't need second battery ... and I am ordering the 2000mAH extended battery for GSM model. Having extra 250mAH is nice, it's a bonus for additional 30 minutes screen time! ... while still having the same look and thin device profile

Hey guys can someone recommend a good place to buy a second battery and charger if needed? Is it worth getting the extended battery and do I need to buy a different back cover if I purchase one? I am in Australia so was thinking eBay might be my best bet? Cheers

I do the same as the OP. I have three batteries that I rotate through. The OEM Samsung battery that came with the phone and two 1900mah batteries that I bought from eBay (which aren't too bad by the way) . I don't ever have to plug in my phone anymore because most of the time I have two fully charged batteries ready to go. I get on average between 12-15 hours on a single charge as it is with pretty good use, so I'm not worried about my phone dying, its just more convenient.

What about if there is going to be an official larger battery for it?

Just bought two off of eBay for $11, bargain. Hopefully they will do the job. Can keep one in the car and one at work, I should never run out of battery

I am pretty sure i saw an official Samsung extended battery 3000mah with battery door cover on eBay for the GSM version . I think it was around $35-$40.
