hi all,
I've just bought a 2nd-hand XDA iis and is battery is not so good.
So I intend to buy a new one.
But I'm wondering which bat is the best now.
I've gone to ebay and see that they have some types: original 1500 mAh, 2400mAh, "slim" 3200 mAh and "fat" 3600mAh.
I think the 3600mAh is the most suited for my xda.
Is there any better choice? Where could I buy it?
With the 3600mAh, how long would the xda would last if I use wifi IE with the lowest backlight?
Do any of you have any problems with it?
Could I use my old charger or Do I have to buy a bigger one?
Could I still use my usb-cable (not cradle) for charging my xda?
And is there any conflict with WM5? (I've just read in our forum that someone have problems with WM6).
Thank all of you so much.

I would say that primarly it would depend on if a 'fatter' and heavier phone bothers you.
Keep in mind that just about all the cases and various accessories that hold or clip on to the phone are designed for a phone that has the original battery, so a thicker battery may well make them unusable (cases are the primary example I would give).
How long it would last is impossible to say, as it depends on how you use the phone, what apps are on the phone, and so on. Also, 3rd party battery quality does vary. Which manufacture is the best, I can't say as I've never seen any place that reviews battery life.
I've never heard of any incompatibilities when talking about a particular version of win mobile and a certain capacity battery, and can't imagine that it's even possible.
Pick one and see what you get, then post the results here so the every one else can benefit from your experience.

At last, I've bought a fat 3600 battery and I think it's a good decision.
Now, I can use my fone for browse Internet in near 6 hour with wifi; or I could use it with 5 day stanby (how amazing).
some small problems are:
- the fone is thicker and heavier (no problem with me).
- My third party charger is a bit hotter.
- And the charging time is longer (ofcourse).
do not by batteries by ACME power. I have bought 2400mAh and feel no difference compare to standard old battery. Besides, I have troubles with bt. it turns off by its self with only this battery.
I bought a battery for my Htc Harrier about 4-5 months ago. Sorry i dont know the brand of it but its says its 3200mah and "replacement for XDAIII". The inside of the battery is kind of bloated out from the heat and looks a little dodgy but still works. Ive had a few problems with it where it powers off for no reason. When i turn it on again the battery charge looks fine.
Just a couple of days ago for the first time my phone just completely hard resetted and lost all my data. I again turned it on and the battery charge was fine. im blaming that on my battery.
I use my phone mainly for listening to music on my bluetooth headphones while im driving to school and for typing things out on my bluetooth keyboard at school. The standared battery that comes with the phone simply has not enough charge time to do all this.
With all its annoying problems i still use my battery. I just make sure i back up my most important things on my storage card. And charge it every night.
Soon im going to buy a HTC Blue Angel due to my countrys crappy plans that the Harrier comes with. Maybe i might buy the 3600mah while im at it.
So my advice is if you dont need the charge of a extended battery then stay away. Unless you are like me and need the extra battery power then beware of some stress ahead that it might give you.
I have ordered 2 high capacity batteries for my new HTC HD7 and DHD.
They are simply higher capacity batteries but not made by HTC.
The Desire HD battery is 1600mah (standard is 1230mah) and
The HD7 battery is 1500mah (standard is 1230mah)
My DHD is aweful with its standard battery - I won't even touch it once in the day and after 6 hours it will only have 1/4 left of battery!
The HD7 is much better and seems to last the whole day with call and text use but it is always on its last legs towards the end of the day - I imagine that these batteries will offer at least another 2 hours of good use a day to these phones.
My question really lies in the safety of these batteries... they are not HTC batteries - they are made by some oem somewhere in china I would guess and I don't know if they are likely to leak and damage my phone or not with extensive use. Does anyone have any actual experience with such batteries on their phones?
I did actually buy 2 spare oem batteries for my Nexus One from eBay and have never had problems with them however I have never used them for a sustained period so I don't know for sure...
i am also interested in this. ive seen a few 1500mah batteries on ebay. but my concern is if they are really 1500mah. they could just throw a sticker on there that says so.
as for safety, as long as the batteries output is equal to that of the stock hd7 battery i dont see why there would be a problem
you'll have to let us know how they work when you get em. i might end up just getting one here pretty soon though
It's not recomended and it is risky.Those batteries can really damage your phone and in some extreme cases you can even lose your warranty.You can find this hot topic in various forums, I read a Blackberry user buying one and after 3 months working presumly better the battery started to literally mealt, ouch ! (could have been a bigger ouch btw lol). I'd wait for an extended battery but I'm new to the world of HTC and don't know how they would react. Nokia in 2006 launched a program which replaced some particular batteries and delivered increased cappacity back.
OR buy a 2nd original battery. It's the safest decision and 2460 is still better than 1500
I bought a battery like this for my Treo 700wx. Worked great for awhile and than it started to die really fast. I put back the stock battery and it would even start to die on my pretty quickly. After that, I never would buy another extended battery. Seems hit or miss but just wouldn't trust it again.
^ Exactly. Forgot to add that their cycle life is a lot shorter. While with an genuine one you could go even for years, for an extended one you should expect 6-7 months at best.
Don't buy these batteries. They all look the same and I'm guessing originate from the same supplier. I bought one and it didn't fit quite right, and I worked out the label was misaligned, so I peeled back the label to line it up and low and behold the battery itself said 900mah despite being labelled 1500mah and "replacement for desire hd".
Blatantly trying to rip off users who are desperately trying to get a little better battery life, ironically they are actually getting a lower capacity battery! Beware! Also note, I've had my hd for a month now and the battery life has improved hugely, I always get a full day now! Although its in power save mode by bed time. I have though invested in an external 5000mah portable battery charger for use when I know I'll be away from mains or usb, a much safer option.
Cheers!
Ps this is by far the best smart phone I've owned, iPhone, blackberry storm, palm not a bit as good as this, wish it could deal with outlook meeting requests though, ie accept, reject, send...only fault, and I can live with it for how amazingly it does everything else.

I've bought plenty of generic batteries and have yet to have my phone blow up in my pocket.
Since i upgraded from my htc dream which had a custom japan made 2430 Mah battery iv been searching for the same thing for my O2x and iv found it.
http://www.ebay.co.uk/itm/2430MAH-F...069?pt=LH_DefaultDomain_3&hash=item2eb76a1fad
Its the same asize as the original battery so no gay larger backs for the phone just longer life and more time gaming and browsing, just dont buy them all ill be getting one in a couple of days.
Since they have the tech to put more power into small sized batterys it makes me wonder why these big phone makers dont use these higher capacity batterys instead of giving you some peice of **** that barely lasts a few hours of real use.
If the tech really were available within the requirements and safety measures the big manufacturers would surely deploy it.
This battery probably has nowhere near the advertised capacity, comes without the necessary safety measures like the stock ones and will decline greatly over time.
If you want premium tech you have to pay premium prizes, and while there might be some better bang-per-buck deals, this one sounds to good to be true, so I wouldn't trust it until someone confirms the battery really has that much juice.
Just my 2 cents
Oh why not check it out?
Ordering one now, will tell you all about how it perform as soon as I get it.
I already have confirmed it works did you bother to read my post i bought this battery from the same seller for my htc dream and had bit for a year and it last for almost 2 days with a lot of use, i can't say for sure that this one for the o2x will work as well but its from the same seller and its the same brand of battery from japan so I'm confident and will order one soon.
Remember its made in japan where standards must be kept it isn't from china.

Of course shoddy goods can be produced anywhere but they cannot label them as better than they are that only happens in places like china.
China regually change disk type and spoof them as better brands for sales and clone well known products like the psp and iphone and release crap labbled as psp or iphone this cant be done in japan and western countrys and thats the same kind of thing as labbeling a 2430Mah battery when its only a 1300Mah battery so im not worried as i said i already tried one of these gold premium batterys and it worked fine.
So continue with your scepticism and lose out i dont care.
And remember that when you get a new battery sometimes you need drain the battery then delete battery stats and recharge it or it will appear as tho the battery drains faster than a stock battery and if the stats think the battery is empty it will shutdown.
great find, thanks a lot for sharing.
i ordered one as well since im so sick to having permanent paranoya of running out of juice if i cant plug the device for a couple of hours....

Let's see after some months of usage, I'm usually very skeptic for those batteries with ultra high capacity (1A/h something like 75% more) at those prices.
Producers are not a bunch of idiots, IMO those batteries are simply not good enough.

Please restrain your self from using insults.
As rusty mentioned any country can make crap. And sell them for "some thing they ain't". As you seems to refer a lot to china. It might be a chines battery with a fake label. Wouldn't be the first time. Or the label might have a typo, like I hope your capital M is in all the Mah. Since: M= Mega ,m=mili. Should be written mAh.
Also since the battery is a Li-ion battery be careful with charging it, since if they get overcharged/overheated they explode. Li-ion battery explosion
And I know that the stock is Li-ion to but hopefully of a higher quality.
Well mine is on the way. Guess it will take a week or so, but I will update from day one how it performs.
If the tech is available, the phone manufacturers will definitely use. Longer juice means more profit.
i ordered it as well, i will post an update as soon as i get it.
13 pounds sounds good since, the 3450 bat is 35 + cover....
just my thoughts....

Most rechargable batterys are Li-ion....you know this means lithium right.... 9 out of 10 rechargable batterys use this tech including the stock and they do not explode when overcharged they have chips that stop them overcharging and even with the super cheap version iv never seen one that didnt come with this even cheaper overcharging chip.
But AGAIN i already said i tried one of those 2430mah batterys with my htc dream and the battery life was doubled from the stock battery and i regually overcharged the phone overnight....no explosion. How about we just wait and see what people who have ordered one report.
In case your brain cant comprehend what you are seeing but that guy intentianally made that battery explode and very likely took apart all the safety features before doing it.
My theory on why phone manufacturers dont use higher capacity batterys is cost they want to make the most profit from their phones so why pay higher prices for better batterys when they can get low capacity ones for dirt cheap prices and slap huge price tags on their phones, if they are paying mass stock prices of £8 per battery for 1920mah or 2430mah instead of £1-£2 for crap batterys then that adds up for each unit they sell. Less cost in production means more profit.
For those that want there are a few other threads on other devices for this "brand" of batteries.

Samsung Galaxy S I9000

There's a level of respect and decor that you should maintain in this forum. It makes me wonder if you're some hired salesman from ECell, but that's just speculation and not an accusation.
For the people that ordered this battery, please do give a report of how this performed.Tell us about how hot it gets while charging, what are the battery stats like, and how much real time usage does it give you.
I'm a heavy user and sometimes the battery wont last a day. I will report in how it performs as soon as I get it, so no worries

Ill respond to someone in the same manner that they reply to me if they cant handle it then they should learn to deal with people better.
No i couldnt care less if you think im a hired salesman or some crap i used this battery before on a different phone and battery life was increased alot from stock i dont know if these batterys are just relabbled crap and i got lucky and got a 1930mah battery but in any case i got alot more time from the battery i got than from the stock so it was worth it.
Temp didnt rise much more than stock around 35c while charging up to about 41-42 if i was using at the same time. But that was the htc dream and was an old phone that phone got hot from normal use anyway because the cpu was almost always at full load.
Has anyone tried this GOLD 2430MAH BUSINESS BATTERY FOR DELL STREAK MINI 5 battery here? (Just check it out on ebay, i can't link it because i'm a new user)
Wondering if its worth getting it or if I should just get a cheaper pack with a charger and 3x 1800mAh batteries? Mainly looking for an extra battery to take with me on long car trips so I can use the phone more like a tablet, but I wouldn't hate having a longer lasting battery for daily use either and then using the stock battery as my extra.

this looks interesting..one thing good about it , is that is the same size as the original dell battery.
I think its a fake capacity, the largest capacity that fits as standard size offered by a decent battery manufacturer, Mugen Power is 1800mah, and if you read the threads here, there is a 2400mah extended battery that has to use a custom battery cover because the battery is twice the depth of the standard battery.
So, i think you will find its not really a 2430mah battery, but a 1800mah battery at best.
if it seems too good to be true...
The best bet is to get one of those external battery packs with 3000-6000mah and a spare cable.
Also be agressive in your control of screen brightness and data use
If you read the feedbacks of that seller on eBay. There are heaps of negative feedbacks from buyers calling him a CON.
I bought off amazon since it had to be shipped to India... think there was only 1 seller in Amazon and he seems genuine.
There's a point with batteries where to make them any more powerful you must make them bigger. If fitting 2430ma into an 1800ma package was possible Mugen would have done it, so yes the rating is a lie.

Sorry. Thought you asked for the regular 2400mah.
hi, i bought this battery 2 mounth ago and my phone authonomy is double now. so dont coment if you dodnt try!
Do dell sell them?
Probably a con, but what the heck… I just purchased it. If it’s not 'as stated', I’ll report the bugger.
could keep us posted about this, i looked at the seller's feedback and seems it is fake but wondering if that is true.
The Americans have a saying "You can't put a quart in a pint pot" and that applies to battery power as well. Don't waste your money.
Irritatingly, battery capacity is only shown on the battery itself and not in the device’s battery info. So, is it really 2430mah? Don’t know. But there IS a difference. The 1530mah stock battery ran out of juice alarmingly quickly – like falling off a cliff - when at 30-40%, yet ‘Business Battery’ allows heavy use (downloads, browsing, video… etc) right down to single digits. So now I can use Streak much more (I’d say several hours more of constant use) when battery level is below 50% without worrying if it’s going to suddenly die on me. No gain between 100-50%, though.
I was prepared to slag this off, but from my experience it’s genuinely longer-lasting, especially at low battery levels. How long the battery itself will last only time will tell.
I’m not prepared to test it against Mugen’s 1800mah and spend near 30 quid (plus £18 p&p) in the process.
I've read elsewhere that the cheap Chinese batteries often don't report the available power in as many steps as a 'proper' one does, so they appear to fall slower.
I don't know how old your Dell battery is but it might not be as good as it used to be when new.
Yep, I had to replace the Dell battery (after about 10 months use) because over the past week it became completely unstable – dropping to 70% after 30min use, suddenly back up to 95%, and plummeting from then on. But the stock battery right from the start was always weakest when two-thirds empty, and it drained juice even on standby. Last night it was 100% or ‘fully charged’ for over 3 hours (mostly on standby and some light doc editing)… that had never happened before.
The thing is actually stamped ‘made in Japan’… aren’t Japanese products supposed to be expensive? Looks suspect, but whatever. If it becomes unstable after a month or two then sure, I’ll invest in a nice new Mugen or Dell replacement. But as of now I’m fairly content with a £13 Ecell batt.
Got one of these last week, & have put it through a few recharge cycles etc, unfortunately, it's no better than the stock battery
Oh well, it was worth a try..
As with all cheap batteries it has a short life - no more than 2 or 3 months before it starts to rapidly drain. As a temporary and inexpensive solution it's fine, but don’t expect long-lasting quality.
I'm currently using an old LG Ally, and its age is getting to me. ARMv6 means developers are loathe to support it, 128mb of RAM is a tight fit, Froyo has its myriad limitations, there's no unofficial support for the phone anymore, etc. It was a good phone, for the price, but its heyday has passed, and I need more power for when I occasionally need entertainment whilst out and about.
So, after looking at the available choices (of which there are sadly few when a physical keyboard is a requirement), I'm thinking about grabbing a Droid 4 off a certain auction site, to replace my Ally. One major concern I have, though, is battery life; particularly while standing by. At the moment my Ally can easily standby with occasional usage nearly a week without needing a charge, with the following conditions true:
Gtalk and Checkin nonsense disabled
Auto-brightness customized to only provide needed brightness (e.g. not instantly blaring to 100% in normal lighting conditions)
Data connections off/voice only, GPS off most of the time
Minimal background apps
Of course, extended use of the screen or anything utilizing partial wakelocks tends to cut that time significantly, but time in-use compared to standing by, the phone spends far more time standing by.
So. Given the above usage and applicable settings, how long could I reasonably expect the Droid 4's battery to last? Would I actually be downgrading in terms of time between charges, like some of what I've read suggests?
Don't really know, over 24 hours, if running stock ROM or a modified stock with all unused apps disabled.
If I remember correct I got a several days, when I had forgotten it was on, but was not activated on a carrier.

Hmm. On the Ally, the primary power draw is the screen, with the awake cpu and wifi coming in second and third respectively. Are the main draws the same on the d4, or is the power inefficiency coming from somewhere else?
Just look at the specs
http://www.phonearena.com/phones/LG-Ally_id4498
http://www.phonearena.com/phones/Motorola-DROID-4_id6431
Specs Ally / Droid 4
Battery: 1500 mAh / 1785 mAh
Processor:Single core, 600 MHz, ARM11/Dual core, 1200 MHz, ARM Cortex-A9
Talk time: 7.50 hours / 12.50 hours
Stand-by time: 20.8 days / 8.5 days
---------- Post added at 10:55 PM ---------- Previous post was at 10:46 PM ----------
The power inefficiency is coming from the 4 times faster processor and only 15% more battery.
I wouldn't think it would make that profound of a difference, though; the CPU should be offline for the majority of the time when the device is idling with the screen off.
I'd also assume that the 4x faster processor wouldn't use 4x or more the power, even with two cores, considering it's both newer (advancements in general processing efficiency can be assumed) and on a smaller process (45nm vs 65nm).
It's looking more like a problem of how it's used, rather than the hardware itself (though the battery is, as you point out, piddly for the device specs it's running). I'm tempted to pick one up now just to see how long I can get it to last.
I'd noticed the official standby time that you quoted before I started the thread, though, and considering those times are generally greatly inflated...it's a little worrying.
First I would disable all know safe to remove bloatware see
Disabled app/bloatware list
There are 71 apps in the list, some may require rooting to remove/disable
or
try a modified stock rom like
[ROM]D4 stock De-Odexed JB 98.72.18
Wow, 71. That's an exceptional amount of garbage.
I probably would have gone and used CM 10/11 or a ROM based on them, is CM not stable enough to use over a stock derivative on this phone?
Cm does not get as good of battery life as stock jellybean

Ah, I see. Modified stock it is, then.
Guess I'll look into picking a d4 up to play with. Thank you for the information and your time.
if it helps you get a general idea (using the extended gold battery) i can probably get a day and a half of stand by time and i always have LTE enabled. this is using CM11. you can probably get 2 days or so if youre not using data but dont take my word for it. the screen has been the biggest battery hog for me and i keep my brightness at 10%~ most of the time. i highly recommend you look into an extended battery because the stock is pretty weak. the gold extended one is around 15 dollars while the mugen is 90~? dollars but mugens battery is way better with the only drawback being its massive size which can be a benefit to some people depending on how you plan to use the phone
I have everything "enabled". WiFi, Bluetooth, GPS, 4G. In short: My phone is running at maximum potential. With that being said... on Standby, it lasts about 24 hours. ~4 hours with the screen on and the phone actually being used.
You don't really notice it if you're like me and never use the damned thing, but I'd suggest grabbing an external battery, if you can. It's definitely an upgrade from the LG Ally. I used to have that phone, myself...
Thanks for the replies, guys. I've actually bought a D4 and am currently waiting while the seller takes their sweet time getting it into the mail. Pretty eager to get my hands on it, it's been a while since I've had some new (well, to me) tech to play with.

What ROM do you use?
The lack of screen-on time really doesn't surprise me...the whole TFT display/fairly quick processor/small battery combination and all, and the assorted radios take a fair chunk. Still, it doesn't bother me all that much, as I'm already used to the Ally's fairly mediocre screen-on life. Quite the contrary, really; if I can get the same life out of it at much greater performance levels, I'll be pretty satisfied.

if it helps you get a general idea (using the extended gold battery) i can probably get a day and a half of stand by time and i always have LTE enabled. this is using CM11. you can probably get 2 days or so if youre not using data but dont take my word for it. the screen has been the biggest battery hog for me and i keep my brightness at 10%~ most of the time. i highly recommend you look into an extended battery because the stock is pretty weak. the gold extended one is around 15 dollars while the mugen is 90~? dollars but mugens battery is way better with the only drawback being its massive size which can be a benefit to some people depending on how you plan to use the phone

Hmm, not terrible, but not especially good either considering the below. I have a few ideas to try for stretching the battery out, and am planning on trying both modified stock and various CM flavors, so we'll see.
Are you talking about this battery?
I was under the impression that any battery larger than stock would need a different backplate to fit (though to be quite honest, without handling the phone I haven't gotten much of an impression as to the various dimensions of it)...if that's not the case, I'll definitely look into grabbing the gold battery.
Just how much room is left with it installed? Is there still enough room to, say, slip an inductive charging receiver in there?

That battery is same physical size as stock, just rated higher.

...how?
Maybe I'm just having one of those moments here, but the last I was aware of, there was a fairly consistent relationship between capacity and size/weight when it comes to li-ion batteries. I don't see how they could possibly be getting 50%+ more capacity out of the same footprint without utilizing recent advances in anode construction (unlikely) or using li-po and utilizing wasted space in the casing (not advertised as such, and a third or so of the casing being empty seems unlikely). nevermind, I thought the D4 was using a traditional plastic-encased li-ion.
I hate to call BS on something another member is apparently having some success with, but it doesn't seem possible :\
as stated by sd_shadow its the same size as the stock battery but keep in mind that the gold battery does not come with the sticky glue that holds it against the phone and in my case the backplate is fairly easy to come off and i dont think its very good for the battery to be hanging from the flex cable thats screwed into the phone.
the 99 dollar one by mugen power is way bigger and they provide the modified backplate with the battery so you dont have to worry about that unless you plan on getting clothes for your phone
if you get the official wireless charging backplate then you will not be able to use any clothes on your phone because its thicker than the stock one.
Ehh, problem being that I'm not really interested in spending another $100 for a battery on a phone that can be had for around $30-$40 used.
I'm hoping to work out some way to quickly swap batteries, so I can just carry a spare with me. I like to think I'm decently crafty, and I have way too much time on my hands these days, so...we'll see once I eventually get my hands on it.

I don't generally put anything on my phones anyway, aside from the mandatory Skinomi screen film. Regardless, what I had in mind was doing this, possibly reworked to add poppable connectors instead of hard-soldered connections.
Not really interested in overpaying for Motorola's monstrosity of a solution when there's a much more elegant option available.
there isnt really an easy way to have a backup battery on the droid 4 thats easy to swap unlike say droid 3 where you can easily pop the cover off and swap batteries. the battery on droid 4 is screwed in by 2 small screws and if you lose em your phone probably wont work until you get replacement screws
i had to make a battery change this weekend because i carry my stock battery along with the screw with me just in case and its honestly a pain unless youre in a well lit room with a table
your best bet might be to get a portable usb charger that would be usable for other devices as well. i have no experience with them but it seems a lot more comfortable than asking someone to hold a flashlight while you change the screws.
but keep in mind that if youre just listening to music you can expect the device to last about a day so needing another battery might not be for you

Wondering about that, actually. From what I've seen, all the screws do is press the ribbon cable down onto the ubiquitous springy interface pins, right? Plastic-encased batteries (like, for instance, my Ally's) provide the pressure with their weight and rigidity, rather than baffling design decisions like...well, a separate ribbon cable.
Though we don't have a particularly rigid battery to work with, it shouldn't be too hard to figure out a way to provide pressure to the pins without using screws. How solid is the battery door when it's locked in place?
I don't anticipate actually needing to be able to swap batteries on the go; after all, I thought I'd need to with the Ally but eventually tweaked it to standby properly - but figuring out if and how it can be done sounds like a fun exercise.
on a previous post i said that my back cover is fairly quick to slide off but i cant speak for others as my phone is from ebay. its supposed to be refurbished and the back cover was new but its still pretty bendable
the battery is held inside mainly by the glue and the screws. there is room for the battery to wiggle around if it doesnt have the glue which is what happens with the gold battery. if you remove the backplate and make the battery face the ground then its only gonna be held by the flex cable that doesnt stretch so its not something i advice. when i use the gold battery im very careful to never let this happen
the contact pins are held down by 2 screws and theyre covered by a small plastic piece thats pretty easy to remove by hand
if you think you can work something out than congrats but this is the biggest design flaw droid 4 has in my opinion

Yea, I saw that. I was referring more to its front-back/vertical strength, whether it could handle holding something against the battery pins.
Bendiness would be a problem, though.
Fortunately, what I have in mind shouldn't involve the back cover at all.

How much vertical wiggle space are we talking about here?
Reason I ask is, I've been looking into batteries for similarly-sized phones. The Optimus F5's battery dimensions look promising, and it's apparently either a 2150mAh or 2460mAh part (this comparison page says 2150 for OEM, but I can't seem to find such on ebay).
Both sets of dimensions are from "gold" battery listings, for consistency:
Droid 4: (7 x 4.8 x 0.4)cm / (2.76 x 1.89 x 0.16)" (L x W x H)
Optimus F5: (6.5 x 4.4 x 0.5)cm / (2.56 x 1.73 x 0.2)"
Slightly smaller, but 0.1cm/0.04" thicker. Is there enough room?
