New Battery

hello everyone,
i am planning to buy a new battery for my O2 XDA II but i was just wondering whether it will make any difference in the total running time? my device currently runs for two days with normal usage.
and on average how much does a new battery cost? it is $15.9(australian) on ebay.
thanks for replies in advance

im am using this battery for my XDA, it is larger, and with bigger capacity, note that the origina battery has 1200 mAh capacity, this has 3600 mAh. it really extended the usag time of the XDA, altough it is now BIG to look at.

two days with old battery and normal use is not bad at all.
There are several sellers of 1800, 2400 and 3600 mAh batteries. Because of bad experience with "original Minolta" batteries on Ebay I'd prefer buying from shops that have a reputation to loose.
Ebay feedback is unreliable. Buyers can only give feedback based on if they received the goods and if the goods look like the description. Plus giving negative feedback almost in every case leads to getting negative feedback as well. The seller who sold me fake minolta batteries had 50,000+ feedback, 98% positive. The batteries looked genuine and performed well for over a month. One month later his negative feedback started to increase, he never answered my warranty claims, next month his account was gone.

Battery??
can anyone tell me approx. how long would a new battery last on a hima?
1200 mAh? 1400mAh? 3600mAh?

actually no, nobody can. It highly depends on your personal use, the software you use but most of all:
-the time per day your LCD/Backlight are on
-the brightness settings of your LCD
-how often do you turn it on/off per day
-is IR on or off or on for some time per day
-is bluetooth """""
-how often do you recharge and do you recharge till max capacity
-the quality of your charger
-Do you use it in combination with other hardware like headphone, thumb keyboard...
and so on. It might depend on the radio version that's never been fully studied in this forum AFAIK
but to compare mAh capacity is simple math. If 1200 mAh lasts 3 days, 3600 mAh should last 9 days in the same device with the same use.
Unreliable manufacturers exaggerate capacity.

hi, im a very heavy user, meaning my xda is almost always turned on for i am using unlimited texting feature of my phone, my average text per day is around 400 text messages and 30 minutes of calls per day. my battery (3600mAh) starts at 99% after 24 hours, it may have 25% left, good for another 4 hours use. Please take note that my phone rests for 8-9 hours as i sleep anyways, so continuous use of the 3600mAh batt may be 20 hours CONTINUOUSLY, my backlight is set to minimum and im using WM6.1 OS.
note that with my old 1200mAh batt and my heavy use, the old batt wont last 1 day.
also, im not an ebay seller, i just gave you that link as i had no problem with that seller.

sounds indeed like a good battery, so a good seller. I'm very proud that it takes me 4 hours to completely drain my old 1200 mAh. 5x as much from a new 3600 mah... I guess I'll have to order one...

please also take note that new batteries needs a couple of charge/drain/charge cycles before you will see the effect its large capacity. so give it 2 charge / drain cycles before you evaluate how good it is for you.

@paulpax
Liked the E-bay linked; I'm intersted. Too bad it's E-bay, if only I can communicate with the seller in some other way...

that seller has a phone number in his ebay store, i use that number to contact him when i make my orders, to date my orders have been, 1-3600mAh XDA2 battery, 1-700mAH Tanager Battery, and 1-Canon IXUS battery.

thanks.

...sounds definitely interesting! It seems to be a company in Hong Kong. Are the $46.95 quoted therefore HK Dollar? ;-)
Any first-hand experience?

ill wait till i see some real life reviews before i get one of these but it sounds promising!

I have mine on order now. Upgrading to a 1500mah battery made a decent difference in usabillity, hoping for the same difference again in a step up to 1800mah.
Should get two days battery life out of it then between charges

Friend..Do not forget to post your experience in Detail.
Your experience will make 100's other crying people happy or sad....(they will decide whether to buy this or not)

Link to Mugen battery
There's a link for this battery, but I can't post it because I'm a new user, just google Mugen.
I'm considering buying this for my T-Mobile/HTC MyTouch 3G Slide, if it's any good. I'd like to find a dock to charge this battery! If anyone finds one, let me know.

any news yet? I wan't to know the result

Did you get the battery, or is it still on its way?
Edit: Someone on a Dutch forum has this battery and will report in a few days. I will post his findings here!

First review from a Dutch forum (translated from Dutch, so it might be a little iffy):
I've got the Mugen Power Extended Battery for HTC 1800mAh Legend BB00100 a few days now. Enough time (following the instructions) to fully charge and empty the battery a few times. I drained the battery by leaving the phone running Google Maps navigation. Yesterday and today was the first normal use.
Old situation: Before I had this battery, I was happy if the battery could make it through one working day. With light use in the morning, and in the evening with 40-50% left to do some web browsing. If I didn't put it on the charger at night, the next morning it was about 15%, not enough to start the day. Under normal to heavy use I never made it to the end of the day without charging in between.
New situation: With the same kind of usage it's about 70% in the evening. Again some web browsing before bed and no charger. This morning there was still 43%.
Conclusion: I still put it on the charger because I'm still unlikely to make it through an entire day. But what's clear is that I can make it easily through one day even with heavier use, no more charging in between. That makes the purchase worth for me.
Don't expect that you now can navigate for hours without draining your battery because that won't change. That was exactly what I hoped it would cause. Nothing more annoying than a device to with normal to heavy use that won't make it through one day. Striking is that the Battery Graph program (from where I get these measurements) shows that this battery longer stays at 100% and about as steep downhill runs compared to the standard battery.

so, to resume... even with the 1800mah battery, heavy use will make legend go for just one day...lol
this is intriguing to me...
how in the heck can a Samsung Galaxy Spica GT-I5700, with android 2.1 (there is an update for it now) last about 3 days with normal-heavy use, with the original battery of only 1500mah?!?!?!?! something is very wrong with Legend power usage...
PS. I've seen with my own eyes what I've said about the Samsung...

Yeah, I know it's strange.. Maybe the rom cookers can find out what's causing the power issue.

that would be nice, but I don't know what is the technical skills required to find out...

I can use the battery for 2 to 3days with browsing and some navigation (and 3G is always on, GPS only when needed). BUT: I use taskpanel lite too autokill most programs on standby, really made much difference for me
Sent from my HTC Legend using XDA App

The reviewer from the Dutch forum said that the battery does what it stands for.. So it will add about 30% battery life and it will hold up better under heavy use.

Hi,
What about the size of the Mugen Power Extended 1800mAh Battery? Is it the same size as the original 1300mAh one? If not, how much bigger it is? Any photos?
On Mugen website it says:
"The extra size and weight increases pale into insignificance when you consider the true convenience the battery gives... it represents excellent value for money."
Thanks!

For the legend, the battery is the same size as the original (it has to be, since you can't remove the entire back of the phone and replace it with a larger back).
Weight? Not sure if it will be much heavier than the original.
I ordered mine and it's on the way, but it could takes weeks to get in

Mine is also on the way, and I was thinking about doing a mini-review of it. Not done like the other one here, but with the method mention earlier here: With the screen at maximum brightness and video running running and see who lasts the longest. Any other method? Maybe with a benchmark-tool standing at repeat, if there are any?
Suggestions?

2150mAh + Extended Door

EDIT: It's here!
http://shop.htcpedia.com/index.php?dispatch=products.view&product_id=819
It appears to be OEM, and is gonna be much cheaper than the crap out now.
My main issue, what cases are gonna fit around this nicely?
I don't want it to be a fatso.. Then theres also the issue of heat, considering the larger battery and a case on top.
Thoughts?

I see at the bottom of the page they are suggesting to buy the brackettron car mount.
Does that mean the official car dock won't fit with this higher back and battery?
I really want the bigger battery, seems i'll have to get a new dock too.

Correct, the phone will be too big to fit the official car dock with a extended battery on it.

What I recommend is buying the battery and holding off on the car dock. Is the battery gonna make THAT much of a difference? Really?

It comes out on July the 6th... your post says June... just fyi

They better make a rubberized case for that thing.

Thanks for the info, but think I'll wait for the Seidio 3500mAh

Changed the month, my mistake.

After reading the thorough comparisons of OEM and aftermarket batteries in the N1 forum (by user dougie i believe?)
I thought it would be a better idea to wait for an HTC extended battery.
Save money, and guaranteed quality.
I haven't tried seidio products so I can't say they are bad, but i'd trust HTC over them anyday.

I've used their cases and extended cap batts on BlackBerries and, now, on my DINC. Probably had 6 extended caps on BlackBerrys, and their holsters are the only ones I'll use - nothing but the best quality and design.
As for the extended cap batts, they perform the way I'd expect them to. I've had not difficulties with them, nor have I experienced anything that would keep me from continuing to buy their product in the future. The only "downside" is that yes, they tend to be on the pricier side but, again, worth it. Just my opinion and experience though.

i oredered the verizon 2150 battery wounder if anyone will make cases for this monster of a battery. currently i have body glove case would like another that will work with this battery

Now you tell me about the new 3500 Mah battery.
Just got the 2150 mah from Verizon. Not able to make it through a day. So yes, I am a heavy user. I have the shut down apps. done and the check for 7 different email set to much longer intervals. Video is where the draw back begins. I am going to try and return the 2150 battery. I don't mind opting for the bigger battery if it gets me through the day.

I already have this battery it 4 days now just a little bulky on the back but its easily lasting me 2 days. Last charge was @ 7:30am on the 17th its now 11:05am on the 18th and i have 54% battery still and i noticed while i was sleeping that wifi was left on

Like with any battery, you need to condition it first. It needs to go through 3 or so full battery cycles (completely charged to completely dead) to get to its full potential. If you did not do this, then you are not getting accurate results. I received this battery Monday, and its just now getting to its full potential. I've gone 2 full days without charging on normal use and one time I just laid it all out turning bluetooth on, GPS, leaving wifi tether on (even though I wasn't always using it), had all my accounts syncing every hour, and left an irc chat open in the background and still got well over a day of use.

Lithium ion batteries don't need to be cycled this will do nothing for battery life. Nickle cadmium on the other hand does need cycling.

Dozens of members and thread posts would disagree. And mine has increased every cycle since I've got it.

I don't know about conditioning.
My first charge I got over 28 hours out of it till 14% warning came on. Then 5 more hours till it came down to 10% battery left.
GPS, WiFi always on. and over 5 hours of talk time with that first charge. Something's wrong with your situation. Check all apps.
PS. I have Task Killer, but it ONLY runs when I tell it to kill apps manually. And I manually select the app to kill each time. (easier than going into settings>applications>yada yada). ATK does not run on its own on my phone.
---
2nd charge on my battery.
GPS, WiFi always on
Bluetooth Off
About 1.5 hours of total talk time today.
13:01 uptime
2:49 awake time
Voice Calls 27%
Cell Standby 21%
Phone Idle 19%
Wi-Fi 13%
Android System 12%
Dialer 4%
Display 4%
67% battery left
I'm on track to gettig another 28 hours of phone being "on" till next charge, if not more.

Well just ordered one since my 1750 is not holding up like when I first got it...
Sent from my ADR6300 using Tapatalk

Ordered the 3500 Mah today and found out that Verizon will take the 2150 back as long as it is within the 30 days. I am trying the cycling and what I see happening is that the longer I own the phone the less I am looking at every item and spending time looking for Apps. This in turn means the screen is on less time and so the battery life is becoming longer.

I am pretty impressed with the 2150. After 36 hours .. comprised of slightly above moderate usage during the day time.. I got about 21% left. GPS and Bluetooth were always left on.. used navigation for about 30 mins a day.

Mkk members may disagree but it is hard to disagree with facts which in this case full discharge and recharge is considered a placebo effect. Due to the fact that "lithium-ion is memory-free in terms of performance deterioration but many batteries have fuel gauges." Aka "digital memory" what this does is reports to your phone how much estimated charge you have left.

[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...
Here, read "all about it" from my experience in another parallel forae - "conclusion" after testing, on post #21: http://forum.xda-developers.com/showthread.php?t=1305779

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.

Extensive Review - Mugen HD2 Extended Battery 2,600mAh

Disclaimer: I know there is already another thread on Mugen HD2 Extended Battery 2,600mAh, but I would like to state that this is an official review since Mugen has provided me with a review unit to debunk the many bad comments given concerning their battery quality. This you can read from http://forum.xda-developers.com/showthread.php?t=1294124.
[BACKGROUND]
I have contacted www.mugen-power-batteries.com directly after hearing many comments concerning their false claims. I was surprised that they actually responded by providing me a review unit of the 2,600mAh. It is now on the way.
My review unit will be coming in about 2 weeks time. I will try to conduct an extensive review to determine the actual worth of the battery and whether they work as advertised. I will be conducting a few tests specifically on the battery, as objectively as possible. This would cover video playing, 3G usage, full valuation of the battery charge (using battery widget pro) to name a few.
If you would like a particular test to be conducted on the battery, please state and give a few ideas below. I will be comparing them against the original 1,230mAh from HTC.
I think as faithful users of our HTC HD2, I would really want to get the best extended battery. If this provides even 90% of the advertised capacity, it is already worth the money. Anything less would be pointless.
Thank you.

Larger cell will indeed be good but 2600mAh will be higher than reality as Mugen have admitted this already in a round about way on responses to another testers results.
A new standard HTC cell & new standard size 1500mAh Mugen is the test that needs to be done.
Any chance of a sample 1500mAh review unit ?

This was response to Dougs battery testing.
Not in any way slating Mugen but the mAh ratings marked on their cells are higher than what would be achieved in any lab test.
1500mah is the one I would love to see tested side by side with genuine cell in device & technician mAh testing.
Mugen cells are ok quality but for the asking price we need total transparency on actual cell capacity ...

I have no idea how good that battery is, but I bought this one about 6 months ago and it's working very well, doesn't gain much heat and it doesn't discharge itself much. Average battery consumption in standby is 6mA. All I can do is recommend you guys this one. And cover is really strong. And it's "bit" cheaper than Mugens
[email protected]/MB434B/review_MB434B.html

looking forward to seeing your test results...i just got me a 2400mAh battery and it lasts me about 15hours under heavy use...

Hi guys,
Sorry for the silence... I just received the battery today! Give me some time to get it charged and conditioned for testing
Let me know what else you would like me to test it with.

Display use is interesting for me, such like browsing etc.
Open a browser with some ads or something and look how long the Battery live..
My Galaxy SII gets there 4,5h.
Start the Match

Idc really care about that battery. I know its fake, but is there any real battery that's better then the original stock? 1400, 1450, 1500?? Not the fat ones with the kickstand

Just an update, I am still conditioning the battery. The first charge/recharge was really pathetic, at 12 hours before it was flat (moderate-heavy use). The second charge/recharge is much improved, I am on 25 hours on (moderate use) with 25% left (taking pictures, listening to music, games, surfing, etc.). I will begin formal testing after 4 full runs to find the optimum condition.
One things I have to say is that the ROM does play a high factor. I was on Dorimanx 3.0 and somehow the governors for oc/uc is not working properly as I kept getting some high drainage. Once I reverted to 2.9, the drainage was gone and it seems to sip battery at a much, much lower rate.
So many factors!!!!
By the way, I really like the battery cover. It is not cheap like the other China made products (unlabelled). I have already 4 different covers, and while I would prefer a metal back cover, this is the 2nd best

Can You please also start the heavy display usage test?
And put some pics please
Greetings

Just an update, I am still conditioning the battery. The first charge/recharge was really pathetic, at 12 hours before it was flat (moderate-heavy use). The second charge/recharge is much improved, I am on 25 hours on (moderate use) with 25% left (taking pictures, listening to music, games, surfing, etc.). I will begin formal testing after 4 full runs to find the optimum condition.

I have a few questions which i hope you dont mind answering:-
1. How did you recondition the battery?
2. Does your kernel recognise the battery's full capacity or do you do a battery pull then it jumps back up significantly? Im facing this problem at the moment...
thank you in advance!

how long will the battery last for heavy use like playing 3d games?this is important as i use my phone for gaming most

1) I conditioning it by charging it overnight for 6-8 hours and then depleting it until it powers off (Actually, this is based on the instructions they gave in the parcel). I need to do it 5 times. Once done, I will be able to charge and stop charging when the indicator hits 100%. I basically use Battery Widget Pro (they have a feature called 'calibration'). Apparently, the battery itself states that it is 2,300mAh, but I think this is not accurate (hence the testing). You will know that the battery is fully charge when the indicator goes down to 0 (zero) mA (shows that the battery is not receiving any more charge).
2) Most cheap batteries have wrong indicators (e.g. temperature detection is not working, no indication of battery capacity). And yes, they suffer the need to 'pull the battery out first' before an additional amount is given. I bought one a while back, apparently one that has 3,000mAh. My observation is that the indicators are really gone. In fact, it will slowly go down to 50%, after which if you pull, it will give you 70%, once it goes down to 15%, it will last for a long while (30 minutes of browsing over 3G) before going down to 14%. Using that battery, I have been able to last 31 hours of moderate use (1 hour of music, 1 hour of gaming - not 3D, a few hours of browsing and a lot of photo taking). It costs only USD12 (thereabouts), which to me is the best deal yet. Down side of that battery is the very poor back battery cover. Using Battery Widget Pro (you have to charge fully and discharge until it shuts down and charge up again continuously), I got an estimated charge capacity of 1900mAh. Not bad don't you think?
The Mugen 2,600mAh easily matches my fake 3,000mAh one. The question is by how much. Sorry for the delay but my HD2 is my daily phone. So, I cant conduct full test like Engadget and other websites. But I'll do my best

Idc really care about that battery. I know its fake, but is there any real battery that's better then the original stock? 1400, 1450, 1500?? Not the fat ones with the kickstand

Try Andida batteries. I had the 1600mAh one and it was slightly better than the original (giving me about 1300mAh). I had that a while back.

After much charging and recharging, I can confirm that the battery has about 2,200+mAh. See the attached images to see the estimated calculation using Battery Widget Pro.
Charging takes about 2 hours plus using the wall charger. The last 2% takes the longest.
As per request I ran 2 emulation apps (sorry, no 3d games), fpse & n64oid. The former ran Strider 2 while the latter ran Legend of Zelda: Ocarina of Time. Do note that I have overclocked my phone to 1.6ghz. All in all, it ran for 4.5 hours with 15% battery left. I'm pretty sure it could have clocked 5hours easily. I think that it is a good performance for 2.2kmAh battery don't you think? See the images below for a read of what other apps I was running. I managed to deplete the whole charge after nearly 10 hours of extremely heavy usage!
What do you guys think? Okay?

[Not the Mugen 2,600mAh Battery]
As an aside, I took and strip out the cheap battery which I bought for USD10, which claimed a 3000mAh, which only was about 2000mAh (+/- 200mAh) and took some photos of it. I can understand these extended batteries better. I am not an electronics person, but this would explain why it takes a restart to 'recognise' the 'remaining' battery on our devices.
Notice that they are basically two lower capacity batteries which are slapped together with the thin connectors and wrapped together with scotch tape.
I am not sure whether Mugen's the same, since it does not suffer from the 'restart-phone-to-get-additional-battery-reflected' scenario. However, I wonder whether there are any manufacturers who would just manufacture a genuine 2000mAh without merely slapping two products together (like in this picture). In light of this, it is much better to carry an external battery charger (anything more than 6,000mAh around!).
Anyone with electronic expertise want to comment on the pictures, please do.

Opps, forgot to add the photos of the battery and the battery cover which I mentioned. I find that after the first fall (yes, I tend to have accidents with my HD2 ... ) there is a slight creeking sound with the battery cover (nothing is chipped though). It is a rubberised battery cover, unlike the original metal cover. Still, the feel of the cover is great to the touch.

I am no longer using this device, but my dad is! It still works and have survived loads of damage... mostly dropping the device with the battery cover!
