As we all know the battery life isn't the greatest for this phone so I was wondering if anyone could give me some suggestions on good external battery packs.

I have two that I own. For a single charge (or a couple from ~40%-~90%), I use PowerGen 2900mAh UltraSlim Power Bank Charger. It's small enough that if you wanted to you could Velcro it to the back of your Razr and has a built in Micro USB which is handy.
For longer stints away from power (travel, camping, etc.) I have the New Trent iCruiser IMP1000 which gives me 6+ charges and is still fairly compact at 4 x 3.75 x 1.125 in.
Thank you.

I should add that I have found using Juice Defender Ultimate, I rarely have any power issues. With normal use (30 min stream audio, some camera use and pretty frequent use of text/email/checking in on forums) I can easily go all day on a charge. I'm at 12 hrs and 51% right now after a typical day.
So if you haven't looked at JD, I'd recommend it. They have a free version and two paid. You can compare their attributes here. I went with the Ultimate and figured I'd grow into it, which has happened. The more familiar I got with it the more I find myself taking advantage of it's flexibility and options. Definitely a great app!
Here's my review of the New Trent IMP99D. It has a slightly smaller capacity than the New Trent that Sally talked about, but mine can charge two devices simultaneous (provided that the second device is a tablet).

Really? It lasts longer than my Bionic which was longer than my Charge which was longer than my Dinc.
I think that for the size of the phone, the battery life is FANTASTIC! However, if you invest in the New Trent like we have, you'll be happy.
battery life problem
My battery last at most 12 hours under moderate usage.. Is that normal? I really want to get an external battery charger that is below 30$
Where can I get it? Any suggestion

PowerGen makes a nice little 2900mAh charger that's $27 at Amazon. It even has a built in micro USB cable.

One more vote for the New Trent ^^
check at your Verizon stores for the Motorola external battery pack. The new one has a grey USB cord and sells for $40, but some stores still have the old ones with the blue cord on clearance for half the price (I ended up paying $16.50 total with my company 20% discount). They're the same exact thing as the new one but just with a blue cord. I've been happy with mine, even lent it to a few iphone guys at work to give them a charge.
Also, check stores like Office Depot, etc. in their accessories section. Yesturday I just happened to run across a "iGo" backup charger/portable battery pack (1800 mAh) for $12 on clearance regularly $40.
I tried posting links but I guess noobs on here can't post links.
Anker 5600 mAh slim small, variety of adapters only $39.99 on Amazon.....

SallyC, i have been looking at getting that PowerGen 2900mAh pack. I cant find the answer to this. Can you charge the battery pack through the Micro-usb connector?

Yes, it can be charged via USB.
Fyi, besides the micro USB output charging port with built in cable, there's a micro USB input charging port and a USB female output charging port for charging any device via USB. It also has a LED flashlight.
Is it just me or any one else experienced extreme slow charging on their Droid razr?
USB charging from my PC.. It was almost 3 times faster to charge my previous lg optimus 7 and blackberry storm.

Yes....... AND....
Those other phone don't draw nearly as much power as a Razr.
So the typical PC does not put out 750mA on USB because the spec says they only need to put out 500mA. If you are using the phone while connected to USB it may never charge. It won't drain either.

Agreed. Wall charger is best.

I've not noticed anything out of the ordinary with USB charging vs. past phones I've owned, but have found it charges abnormally fast when connected to a wall charger.

Get a battery monitor app, put it on the charge, see how much charge is actually flowing to the battery... with a 1750 mAHr battery, you can guess the charging time..
From my packard bell laptop with USB charging it gets 850 milliamp...so charging time is around 2 hours.... from a Wall charger it gets 1100 milliamp, so 1.5 hours is enough....
From my HP laptop it has the charging of 450-500 milliamp so it takes around 3 hours...
I have used the manufacturer of the laptop because each USB chipset has its maximum power rating... USB 2 had 500 milliamp at max and USB 3.0 has 900 milliamp of power rating...... so it depends which chipset you are using and which port you are connecting to.....
If getting more confused, try the standard AC charger.....
Also, I think you should make sure to put your phone on airplane mode (or at least turn 4g off) and turn the brightness down while you're charging. This way, more power goes to charging and less to battery draining stuff.
AND if you're willing to spend a little cash, (or you buy your phones at Costco like me) you can get one of the multimedia dock thingies from motorola. It literally charges in 3 hours on there.
Lol.. A wall charger will do fine for me. I've been scouting for the dock, to use webtop application.. But I can't find out over here on Malaysia.
I did find a great widget, battery info, which when discharging, it will display percentage of battery left, and remaining standby time.
However, the best part is, when charging, out will inform you time left to achieve 100% charge.. Its really cool..

... i kinda gave up looking for one.... heck even trying to find the dock for the altrix is a pain... just need to modify the plugs and we can use webtop
Modify what plugs? care to share? I'm interested on this hack..

Math lesson!
The battery is 1750 mAh, that is milli ampere hours.
As such, it will supply 1750 mA, for one hour.
Charging is the same but backwards, 500mA is what the USB port on your PC supplies.
That gives 3,5 hours to supply the battery the required power, assuming 100% efficiency.
But lithium batteries need a trickle charge from 90% to 100%, so that last bit is usually performed in 1 hour, independent of what mAh the battery has.
So on our razr that last 175 mAh will always take one hour to charge.
So that means that we charge 1575mah at a fast speed, that leaves 3,15 hours to charge using USB, and 1 hour to top charge.
That'll give you 4 hours and 15 minutes through the computers USB. =)

Im probably not as heavy a user as some....but Ive noticed the same thing. I unplug my phone at 7:30 and plug it back in at 9-10 at night usually with 20% left and when I stay up late Ive noticed it takes seemingly forever to charge.
I believe it recommended it either the online manual or the quick start up manual to use the charger that it came with. It stated that other brands or 3rd party may not charge the RAZR fast enough resulting with slower than usual charge times.
I have even heard of some people loosing power while it was plugged in and being used. I believe the 3rd party chargers were to blame Like others have said, the USB charging taking FOREVER, a car charger is a little better but not much.
If you download Battery Indicator Pro (from the market) you can set an option on how fast you want the battery to charge via AC outlet or USB.
Will also give you a 1% increment battery display
The Motorola razr can support upto a 1000ma charger..... technically, it means that if u pop it in the wall charger it will charge at 850ma per hour... it will have a full charge in 2 hours.... but a USB port on the PC or laptop is capable of providing only 500ma, so theoretically, it will take more than 4 hours for a full charge....

I just bought razr after owning SGS1 for over 1.5yrs.
the usb charging is unnormally slow! even compared to SGS1 which has 1500mAh.
with SGS1 I used to use it for usb tethering and it charges in about 5 hours to full WHILE TETHERING!
But on Razr idle phone takes around an hour for every 5-10% of battery which is a lot!
I am wondering if there is any kernel fix or workaround that speeds up the usb charging, because this is not natural.
4 hours or even 6 hours is very reasonable charging time, but anything more than that is a lot.
I am thinking there is something wrong kernel wise.
edit: even comparing to HTC EVO 3D which has almost same battery capacity [1730 vs 1750] charges a lot faster than RAZR. and I do mean A LOT!
Hi guys, actually I've noticed this quite a while but I just remembered to post now.
My Razr touch screen sometime behaves erratically during charging; miss-touch, or register touch but in wrong area, auto-touch (not touched but acted as if touched), etc. This behaviour happen most when I use my samsung and htc charger, or my car charger. But with the original shipped one it also happens albeit not so often.
Has anyone of you noticed this too...?
Same here, it is not serious though.
I have that problem too!
yep, same here.
I did not have this problem on my original RAZR but it happens on my replacement one.

Yep, on replamcements you will get this effect. Check Amperage and Voltage on both.
I only get it with non-stock chargers.

Been this way since the OG DROID. Why are you all using other chargers on your phones?
Actually other chargers damaged the OG DROID to the point where it was permanent using certain ebay chargers, flaky screen like reported here, or even where the screen would not be responsive, even after off the ebay charger.

Well, mr syntrix there are few points to address here:
1. AFAIK there are on going effort to standardize wall chargers so they can be interoperable. At least in EU if i'm not mistaken. As consumer, we gotta love this movemement. Shall we not?
2. By other charger we mean not cheap chinese imports but original chargers from HTC and Samsung ones.
3. Shame for Moto if its charger not interoperable since i used HTC and Samsung charger on other phones and it work just fine. Even razr's charger also worked like a charm on other phones. So why not the other way around?
Please moto unlock our boot, err.. i mean, chargers! LOL

Have the problem on both my Maxx and my Thunderbolt. Just figured it was a Android thing...
i know most people will probably say that any car charger will work, but i'm against using cheap off brand chargers. i've read too many instances where off brand chargers over heated or over charged a phone batter. i have a oem motorola car charger for my droid x. i just got a razr maxx last weekend, and curious if the same charger will work with it.
this is the charger i have http://www.amazon.com/Motorola-MB810-Droid-Car-Charger/dp/B003VZQ5VE/ref=pd_cp_cps_1
and this is the charger they say is for the maxx http://www.amazon.com/Original-Vehicle-Battery-Charger-Verizon/dp/B007IJ82HE/ref=sr_1_13?s=wireless&ie=UTF8&qid=1354071848&sr=1-13&keywords=razr+maxx+charger
not sure if there is any difference. the droid x is labeled as "MB810". the maxx is "XT912"
I do not think that this will make any difference at all, unless the charger has less than 5V 0,75A (750mAh).
Btw, i had problems with my original motorola charger (and it broke too) that gave 5.1V 750mAh, and i'm using the HTC touch pro2 charger, and now i can use the phone while charging (as when i was using the old charger, my touchscreen was completely unusable).
What i'm saying with that: do not think that only because it has Motorola (or any other brand name, my sony ericsson charger gave me the same problem) it will give no problems. When something is cheap, it's cheap.
Is it safe to charge a Motorola Droid Razr with a LG charger which has the following specs:
Output: 4.8V-1A
I mean, will it be safe for the battery like its life and other things?
Standard USB chargers should work with all phones with microusb

No, definitly not. Motorola oem charger is 5.1V and 850 mA. You might not notice anything wrong with the batttery in short term but it might cause damage in long term. Plus, motorola have never been the brand that offered compability to other brand accessories.
well this is depressing to read, the charger that came with my razr a year ago was lost about a year ago. i've used probably 20 different usb chargers from different phones but all were older so i assumed the lower amps / volts wouldn't hurt anything, that only a higher amps / volts could potentially harm the battery.
i do remember the charger that came with it had 2 usb ports on it but it was so weak that it could never charge a second device plugged into it
No dude, if it's higher, the phone will only pull the amount necessary. USB is a universal standard. You're fine, no need to worry. If something uses MicroUSB, then it's universal. USB= Universal Serial Bus. Your phone is safe
Edit: For the record, when I had the Droid RAZR, I used everything from the stock OEM charger, to Samsung and everything in between, including an LG charger.
Hey people,
It doesn't mean it's safe to use another brand chargers if your phone didn't get any kind of damage. My xt910's digitizer went weird after i had to charge it for 30 minutes with a genuine htc charger. My atrix's digitizer didn't work while it was plugged into a nokia micro usb oem charger. A motorola phone should be charged with an oem motorola charger, not a stupid lg charger. Micro usb itself is a standart but it doesn't mean you can use anything that fits into the slot safely !
Your phone will be fine

I think it will be fine, I charge my phone with my sister's Galaxy Nexus charger and nothing has happened so far.
USB always uses around 5 volts and the 1A means that your battery will charge faster than using the regular 850mAh motorola charger.
