which is the best battery for xda iis

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.

New Battery Suggestions

I'm planning to get a new battery for my Tilt. The one that I have is almost 1 1/2 year old and it's lasting less than 8hrs a day.
Can you please tell me your reviews of the ones that you have bought and where did you bought it?
Thanks in advance!!

There's a few options, i can't really comment on quality, but while you're at it you might want to look at the "extended" batteries available. I believe the default battery is 1300mAh. There is a 1600mAh one that still fits normally and then theres the uber 2800 mAh ones which comes with a new back cover [obviously making the phone thicker].
The 1600mAh one is probably what i'd go for, as it's an upgrade from the original anyway : Here it is on Amazon http://www.amazon.com/Seidio-Innocell-1600-Extended-Battery/dp/B00133TOJG
Here's the 2800mAh one: http://www.amazon.com/2800mAh-Extended-Kaiser100-T-Mobile-Vodafone/dp/B001AGLIJ0 . I guess it's useful for that extended airplane trip, but it will be bulky..
Note: Amazon got other brands of the same batteries above that are cheaper...so shop around.

How **** is this battery?

Very **** it would seem. I only used tomtom for about 15 or 20 minutes today and played a couple of vids for a minute or two. Nothing else I can think of and no phone calls made. The fully charged battery this morning was giving me low battery status by the afternoon. Wtf? This is the 900 mAh one that came with it.

I last a full day with frequent internet/video/game use. maybe 2.5 hours of that stuff, 1 hour of text messaging, 1 hour of phone calls, 30 minutes of just dicking around, and the rest of the time with it in on in my pocket.
there's a bigger battery available - the model is "BP E270"

well with stock battery i was able to watch 2hour film...than battery was at 10% from fully charged..so battery is disaster....

if you would convert video for hardware accelration - it would not use 90% of battery, only 40% )

if you use a different ROM, some are more efficient with battery life.
also, there are third party batteries as big as 1800 mAh. be warned that this is just the manufacturer's claim and they're usually made in China. I think a site called dealextreme has it for the cheapest but there's a ton of different versions on the net. most bigger batteries come with a bigger back plate to accommodate the extra size. most do not have the "diamond" detailing.

I've got the 1800mAh Cameron Sino and it works brilliantly. I can leave the Wifi on all day, make calls, browse the internet without too much worry of the battery giving out half way through the day. With the origonal battery (900mAh) I practically gave up on the phone and used a Nokia E51 instead. The only downside to the new back cover is as tacky as hell and you need to put some tin foil over the GPS Antenna for it to work.
However, I can actually use the phone now on a day to day basis. Oh and the phone stands on its side now due to the extra thickness so I can watch TV progs etc without holding it.

I might try for a more powerful battery but not one of those oversized ones with bigger backplate. And I'm not sure I'm ready to risk a different rom, I'd frankly be bricking 'bricking' it.
What amazes me is, why did htc supply such a weak 900mAh battery in a phone which undoubtedly requires MUCH more power than say, my artemis, and that came with a 1200mAh battery. Doesn't make sense.

i am converting films for hw acceleration,i use mp4 for hd to convert them and than i use htc album to wact movie....and battery is disaster
also i am using nuedynamicclock but it only helps at night(it should help also when ppc is on cause i reduced voltage for 528MHz(from 1.35v to 1.1v),and i am using rom that is tweaked for minimal battery usage...it helps a little bit but not enough
900mAh is way to low for this device...
also if i want to buy new battery i need also new backplate so my diamond will be fatter???

[Q] eBay High Capacity Battery?

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.

[Q] 2430mAh Battery

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.

REF: Gold Battery 2430mAh on eBay...
Total fake and ripoff!! ...so dont be wasting your money...

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.
