My apologies for not posting earlier, battery continues to deliver great results. This battery actually last the whole day. This days results were 15 hours straight on moderate use and still has 30%. Some of you have asked for a link, I believe that I am not allowed to post links, I may be mistaken. But its the 1800mah Mugen Power battery. Its the exact same size as the stock battery. I didn't need to cut anything on it to make it fit with the original cover, fits in perfectly. Here in the United States, it cost about 44 dollars plus about 3 dollars extra for 1st class shipping. I bought it from the official website, if you find a better deal somewhere else, well congratulations, I hope it delivers its full capacity.

Any more questions? Comments?
[G2 and Desire Z Accessories] crazyC:
I agree with this. No cutting or bad fit, and is better than stock. Not by as much as you would think from the difference in capacity, but I find it noticeable. Now happy with phone life.
[G2 and Desire Z Accessories] detox702:
I just got mine yesterday. I left it on the charger for 12 hours, as suggested, and I've had it on for 4 1/2 hours, 3 of that was constant GPS use with the screen on. I'm at just barely 1/2 charge now. At the very least, this will get me through an entire work shift of heavy use.

1800 mah battery. Cost $49 off Amazon, shipped Friday, got here last night.
[G2 and Desire Z Accessories] philosophics:
If I had the money, I would compare this one to the Andida 1800mah battery and post a thread for comparison for that. I have thought many times about getting the andida battery but don't want to spend money on a battery without more juice. I have been saving for this battery for a little while now. Hopefully, I can get it soon because I do have an 1800mah battery for an Evo made by andida.

Yes, it's not the same but it could be used as a comparison for this battery...
[G2 and Desire Z Accessories] funkeee:
I got this battery. It's a barely noticeable improvement over the stock battery.
[G2 and Desire Z Accessories] dj2muchxx:
You might not have the exact same battery that I have. I bought it from their official website. Not Amazon. If you do have the same battery, did you charge it as instructed on the packaging? If you did not, then there is your problem. If you did just as instructed and it still doesn't work, and if its an exact Mugen battery, just like we have, then you may just have a defective battery.

I would post pictures but I am not allowed to post yet.
[G2 and Desire Z Accessories] riahc3:
The review sucks; Very unprofessional, no model numbers, etc.

This sounds more like an ad than anything else.

Second, do you use SetCPU? Im a heavy user (surfing, downloading, angry birds, etc) as well and out of 24 hours about 6 Id say, the phone is idle and SetCPU kicks in downclocking it to 200mhz when the screen is off. In those conditions Ive seen the phone go down to about 60%

Third, do not tell funkeee his battery is defective. Battery life depends on so many other things such as reception, individual components, etc.
[G2 and Desire Z Accessories] dj2muchxx:
What crawled up his butt? Am I right? Lol
[G2 and Desire Z Accessories] taob:
Could somebody with the Mugen 1800 mAh battery install Battery Monitor Widget (https://market.android.com/details?id=ccc71.bmw) and tell me what the reported capacity is? I'm seeing 1550 mAh on my Desire Z's stock battery, which purports to be a 1300 mAh battery.
[G2 and Desire Z Accessories] cartman09:
I do have it installed and for me it says 1300mah although I have the mugen 1800. Does anyone know? Do i have tell the phone somehow that i am using a different battery now?
[G2 and Desire Z Accessories] JayXL14:
This looks like a great battery but has anyone found it for any cheaper than $45?

That's a little steep for something that apparently doesn't work that well.
[G2 and Desire Z Accessories] dj2muchxx:
It workes perfectly well, the most recent results I have had are great, it went 2 days and 1 hour with mid usage on 1 charge. I'm not posting false results, I don't have time for that. Its all about which battery you have, whether its the real official 1 or if its a fake knock-off from amazon that costs much less. And not to forget the proper charging method.
[G2 and Desire Z Accessories] riahc3:
Once again showing that your "review" is to be taken with a pinch of salt. :rolleyes:
[G2 and Desire Z Accessories] taob:
According to the app, it pulls the data from the OS. I don't know how the OS "knows", though. I'm hoping that it simply doesn't recognize the Mugen battery, and defaults to 1300 mAh. You can manually override the mAh rating in Battery Monitor Widget, but obviously it would be better if there was a way to test the capacity of the battery.
[G2 and Desire Z Accessories] noodles2224:
Anyone from the states have this battery? How long did it take to receive? I am a little impatient plus I stop ordering from hong kong long time ago on ebay. Just because it takes forever :) but I had to get a mugen brand anyways, I want to know approximately how long.. Bought it the 27th of june, 29 it said shipped out.. Thanks
[G2 and Desire Z Accessories] dj2muchxx:
It took about a whole week. I am in California.

HTC G2
[G2 and Desire Z Accessories] noodles2224:
Finally got it today, not bad 9 days .. And from cali, LA :)
[G2 and Desire Z Accessories] funkeee:
It's not as bad as the stock battery, which has gotten weaker since I got the G2 in October.

I got this Mugen battery on ebay for $35 with free shipping. I took a chance, but it came in it's original packaging. After some testing - it is in fact better than stock, but not tremendously better.

With intermittent heavy use (games, surfing, downloads) my battery is at 32%. It would have been dead by now with the stock battery.
[G2 and Desire Z Accessories] gbarayah:
There is a seller on Ebay that is out of Southern California. Has a few auctions up as of this morning. You can Buy it Now for $40. Bidding starts at $35. Free shipping. Being that the OEM stock replacement sells for $39.99 straight from T-Mobile thats a great price.
[G2 and Desire Z Accessories] funkeee:
I got this battery on ebay from 'nakedcellphone'. Good price, $34.95 with free shipping. This was a genuine battery.
[G2 and Desire Z Accessories] dj2muchxx:
I'm not saying that u have a knock off, but when u purchase from ebay, its a risk, so u may or may not. I bought mine from the official Mugen website. I wanted the real deal, and it delivers fantastic results.
[G2 and Desire Z Accessories] funkeee:
That's precisely why I posted the name of the seller, so if someone wants to get the battery from ebay without getting a counterfeit, they can buy it from them.

After a number of tests, I've determined this battery is legit and noticably better than Stock.
[G2 and Desire Z Accessories] dj2muchxx:
Good to see that your getting good results.

My battery delivers fantastic results for me

Hope yours does just as well =D
[G2 and Desire Z Accessories] SiliconKnight:
Just ordered mine will update with results might also buy another g2 waiting for the stock ginger to come out I keep dropping Wi-Fi and it's passing me off
[G2 and Desire Z Accessories] mputtr:
I personally just got the ebay one from the seller that funkee mentioned. I'll be testing it out when i get back to the US so I can see how well it will do.

got it for the base price 34.99
[G2 and Desire Z Accessories] dumraden:
I have been using it since i got the G2. I take it was slightly used, but it does perform perfectly. The thing is, whenever i switch between stock and the Mugen, the phone will hang a couple of times on the HTC Boot logo.... I have to do a battery pull a couple of times to make it work...

Any ideas why?
[G2 and Desire Z Accessories] mputtr:
Potentially might be because of battery calibration and the inherent capacity difference
[G2 and Desire Z Accessories] Flash05:
im using this mugen battery. i can last whole day and a half. 12 hours use, 12 hours sleep and another 6 hours use (not yet empty or below 25%) before i charge it again.

worth it.
[G2 and Desire Z Accessories] taob:
Finally received my Mugen 1800 mAh battery and desktop cradle (damn Canada Post strike!). The cradle can charge the phone and a spare battery simultaneously. I ordered a pair of each (one for me, one for a friend). I'm charging up both batteries right now, and will leave them overnight.

I did a recent test with the battery that came with my DZ: stream audio from wifi over Bluetooth to my speakers. That lasted about 9.5 hours. I'll see how long the new batteries last, and if they improve after a few recharge cycles.
[G2 and Desire Z Accessories] iq-dot:
For those who got the big battery backpack (the one that replace the backcover) how big is it? Hard to tell from the photo if it is as bad as it looks.
[G2 and Desire Z Accessories] The Communicator:
thanks for the review bro, thinking of getting one soon
[G2 and Desire Z Accessories] taob:
No real difference after a few recharge cycles... still easily getting over 9 hours of continuous playback with wifi and BT both enabled. Coincidentally, the battery in my BT adapter lasts almost exactly as long as the phone. :)
[G2 and Desire Z Accessories] devalian:
well, i guess im the weird person here. i got a mugen power battery for my Touch Pro 2. As you know, tp2 using same battery as of EVO 4G.

there is a guide on modding tp2/evo 4g battery to fit into Desire Z or my G2. so i did it!

i believe my tp2 mugen battery which have the same capacity of 1800mah, but it is slightly thicker. but thanksfully the g2 battery door still able to close properly without much notice. Thing is, when i use stock battery, and my desire z got bang into something. it automatically turned off. i guess its because my battery door had come loose and did not hold tight to the battery.

After all, with my constant usage with data on 24/7 and also calibrated battery stats for 2 month. This 1800mah mugen could last me about 15 to 20 hours. Not too bad isnt it?
[G2 and Desire Z Accessories] Spastic909:
Not really a new product. I got my 1800 back in febuary and still love it.
[G2 and Desire Z Accessories] karlonicolas:
its not as bad as it looks. i've got two big battery packs. the problem is, the paint in the back cover of the extended battery chips off after a month of use, and the cover turns really ugly.

i switched back to the stock battery (for a change), and saw that while getting much juice on a 3500mah battery is a pro, the size of the stock battery, slimness of the phone and getting to use the original battery cover, is also a consideration.

FYI, i have been using the big battery pack for three or so months now.

in sum, i intend to get the 1800mah battery prescribed here, on account of the good reviews.
[G2 and Desire Z Accessories] mputtr:
I've been using the 1800mah battery for about a little over a week and the most stress i have put it through is to perform 3 nandroid backups and flashing a different rom about almost 10 times. This is also considering I used titanium backup to restore all my files and configure the phone between each flashes. Over the course of 10am to 11pm i was able to drain the battery to around 20%

so if that's any consideration, take that into account.
[G2 and Desire Z Accessories] porcupineli:
Where can I order it? There are so many batteries on thw web and I heard that most of them are fake...Do they have a site? When I google I get mugen-power-batteries.com...is that the one?
[G2 and Desire Z Accessories] taob:
Has anyone found a place that sells cases that will fit the extended battery door?
[G2 and Desire Z Accessories] taob:
Yep, that's them.
[G2 and Desire Z Accessories] poormanq45:
I just ordered two Anker 1900mah. They are standard sized. They're supposed to fit quite a few phones. G2, TP2, dash 3g, etc...

It cost $22 shipped for both of them. I'll report back after I cycle them three times completely

[G2 and Desire Z Accessories] diablob:
I hope that this batteries will work correctly. I bought some cheap batteries on ebay but were bad. I try mugen and I must say yes, its works!
[G2 and Desire Z Accessories] poormanq45:
I'll definitely post the results. It may take a week to get them and test though.

It seems that I'll have to clip the two corner pieces off and possibly remove the label to get it to fit. I don't mind either of those if the runtime is increased

[G2 and Desire Z Accessories] pearse:
This is where i ordered it from: http://www.mugen-power-batteries.co...nded-battery-for-htc-desirez-t-mobile-g2.html

Only took ~2 weeks to get here too, not bad at all.
[G2 and Desire Z Accessories] funkeee:
Try the ebay seller I mentioned a few pages back, I think it was 'nakedcellphone'. The battery I received was genuine. Another xda member ordered it from them as well. Same exact battery, free expedited shipping, and $10 cheaper not counting shipping.
[G2 and Desire Z Accessories] mputtr:
I'm the other member that got the battery from nakedcellphone on ebay.
[G2 and Desire Z Accessories] pearse:
Ah damn wish i knew about this earlier haha. Oh well excited to test my mugen battery!

Side note: is it just me or is leaving the phone in the charger for 12 hours straight difficult to do, i feel i have to set aside a day to do it lol.
[G2 and Desire Z Accessories] pearse:
How do you like the desktop cradle, would you recommend it?
[G2 and Desire Z Accessories] karlonicolas:
i ordered the 1800mah mugen battery last friday august 5 and got it yesterday evening. i paid for speed post shipping. our postal system is notorious for lost mail and prolonged shipment, but i got the battery fairly quick. good work to the mugen team! i will post my review later about this batter after a few cycles.
[G2 and Desire Z Accessories] karlonicolas:
no i havent and i have tried everywhere.

if anyone here finds a place that sells extended battery doors (hopefully made of metal, like the stock battery door) please do announce.

i am sure a lot of people here are looking to replace the battery doors which came with the extended battery, as the paid chips within a week of use.
[G2 and Desire Z Accessories] poormanq45:
I just received the anker batteries yesterday.

I am on my first charge of them.

To speed up the discharge i am running a 1700/1700 min/max with the performance profile in setcpu.

CM7 nightly 162

Umaro 1.06 kernel

Lcd brightness 100%

I charged the batteries until they said 100% + 1 hour on the included charger just to make sure.

Preliminary results are looking great. I played Angry Birds for 45 minutes and the battery was still at 100%. I'd normally be at 85-90% in that same time with the OEM.

Fitment is a little off due to the battery being thicker then OEM. I clipped the plastic piece and in slide right in. There's a tiny gap that most people won't notice on the back cover. I did notice it and it bugged me. So I removed the label on the battery. Yes, I put tape over the sd card to prevent contact. Once this was done the cover fits just as good as OEM. The backdoor takes a little pressure to get the lock to move, ut once locked it looks perfect.

I'll report back over time. Right now I'm trying my hardest to just burn through these initial charges and having a hard time doing it :-P

[G2 and Desire Z Accessories] mputtr:
when you say that it takes a little pressure to close the battery door, I highly suggest you be careful. Over time that door will bend outwards like a hill. I remember reading and seeing pictures of this happening so just make sure you take a look at the thread. it's related to the chichitec batteries as well (well, the older ones i believe).

there's also a post on how to make your chichitec battery fit in the compartment properly, but i know there was a post that shows you what happens when the battery door requires pressure to close.
[G2 and Desire Z Accessories] poormanq45:
The door closes without extra force. There is still a little bit of a gap. If you apply a little bit of pressure the gap goes away.

I'll keep an eye out for the warping that you're referring to.

Preliminary results are quite promising. I left the phone with the screen set to never sleep, 1700/1700 cpu and it still took 13 hours for the first discharge!

I'm currently working on discharging the second battery

[G2 and Desire Z Accessories] taob:
To be honest, I only bought the cradle so I could charge a battery separately from the phone. I use a snap-on case with my DZ, which means it no longer fits in the slot. If you don't use a case, then the cradle makes a pretty nice stand. Set the phone to never turn off while charging, and you have a decent desk clock. There is a USB passthrough connection so you can mount the phone on your computer or adb to it while it is plugged into the cradle. Pretty good for $23, which is about half the cost of a battery!
[G2 and Desire Z Accessories] taob:
Run something like Battery Monitor Widget to see how much current the phone is drawing. An idle phone, even clocked to 1.7 GHz, won't draw as much power as one that is 100% busy. For example, with my screen on and the CPU at 245 MHz, BMW reports about 115 mA (most of that being the display). At 1.3 GHz, it draws 135 mA. At that rate, it will take about 13.3 hours to drain a 1800 mAh battery, which sounds like what you have. Try running a benchmark in a loop, while Google Navigation is active in the background (so the GPS is on). Crank the display up to full brightness, turn on wifi and Bluetooth, stream music at the same time, download large files to the phone, etc. I've hit over 600 mA at times, which means the battery will be dead in 3 hours.
[G2 and Desire Z Accessories] Jandyman:
Wow . . . Installed the monitor and with screen on. . .nothing really going on in the background its always eating 290-400ma . .this isn't right at all O.o
[G2 and Desire Z Accessories] Jandyman:
I installed the battery ma moniter and it shows while idling on screen . . Nothing going on the background. At stock speed of 800mhz that I'm draining 240 up to almost 400 sometimes, dats not normal I don't think :/
[G2 and Desire Z Accessories] taob:
240 mA sounds reasonable if you have the display brightness turned up all the way, and perhaps a live wallpaper running. I assume you have a rooted phone and have busybox installed. Try opening a terminal window (Terminal or ConnectBot apps, or adb in from your PC) and run /system/xbin/top to show processes that are consuming CPU. Spikes in power usage are likely background sync or other network I/O.
[G2 and Desire Z Accessories] taob:
Oh, and if you do have live wallpaper running, I recommend leaving the phone at the home screen (so the live wallpaper is showing), then running 'top' via adb so you can see just how much CPU it consumes. I was surprised to see many of them keep the CPU at over 80%, some at close to 100%. I have two on my DZ that only consume 5-7% CPU, and that's at 245 MHz (Crazy Colours and Rays of Light).
[G2 and Desire Z Accessories] Jandyman:
I have a rooted phone yes. But I don't have busybox installed and the brightness is at lowest without flicker . .about a fifth of full brightness. And I'm using umarokernal, I might flash another to see if there's any change.
[G2 and Desire Z Accessories] poormanq45:
First report.

I disconnected the phone before leaving for work.

I used the phone like normal. Probably ~50 texts. 25 web pages. 30 minutes of angry birds. Oh, and cell service is terrible. Fluctuating from G to E most of the time with the rare 3g and H.

After an 8 hour day + 1 hour commute I got home with a ~60%.

A little bit more angry birds. About 30 minutes.

Anyways, let it sit over night and then more normal use.

The battery last 33 hours an ~ 30 minutes.

For reference, after a normal day at work the battery would be in the 20% range and hit single digits before bedtime at ~11pm. So, ~16 hours.

Note, I disabled the <40% profile with the new battery that clocks it to 200/800. So it was running full out the whole time!

So far this battery has given me a lot more confidence. I even went out of the house without a charger today!

Thanks.

Can you post a link on where you got this and the cost?

Also, does it fit with the standard phone back?

http://www.amazon.com/gp/product/B0050MUSLY

They are currently showing unavailable.

Here is a single chitech 1900

http://www.amazon.com/CHICHITEC-Bat...4?s=electronics&ie=UTF8&qid=1313511949&sr=1-4

Here's a 2 pack with charger:

http://www.amazon.com/CHICHITEC-Bat...3?s=electronics&ie=UTF8&qid=1313512005&sr=1-3

Apparently the Chitechs are supposed to be a better brand name then the Ankers that I got. I'm showing that the Anker is giving a huge improvement over stock. So I can only figure that the Chitechs would give at least the same improvement.

Yes, the standard back fits. It snaps shut with normal force. There is a little bit of a lip on three sides. If you press on the back a little bit it'll make the lip very small.
[G2 and Desire Z Accessories] malloy0:
Thanks. I ordered the chitech 1900 from amazon. $23 delivered. Hope it works well for me like the Anker did for you.
[G2 and Desire Z Accessories] poormanq45:
You grabbed the single? I was thinking about that. The pair of Ankers with charger was $24 shipped though.

I figured it'd be really nice to always have a second battery charged and waiting to go, just in case :-)

I have no doubt that the chitech will work great for you. Remember that you have to clip the plastic off by the contact points to get it to fit. To allow the door to close easier you'll want to remove the label. Once you've done this you'll want to cover the exposed metal on the memory card door to prevent contact.

Does anyone know where we can get these anker batteries for the uk? Ive had a look around but can only find the 1500mah for desire z, the sensation gets the 1900 :(
[G2 and Desire Z Accessories] karlonicolas:
my feedback on the mugen battery:

it presents a substantial improvement from stock. my phone normally would not last beyond 12 -14 hours (wifi connected, background data synched continuously, with email updated every 15 mins, moderate calls and text messages, around 30mins of surfing and an hour of phone use), but with this battery (1800mah) i am currently at 46% after 10 hours of use. i bought the cheap 3500mah extended batteries, and they seem to be just an two or three hours (of battery use) more than this one.

by the way, i am overclocked to 1600 through unity 4 using cpu tuner.
[G2 and Desire Z Accessories] ptesmoke:
quick question guys, am i understanding a slim htc evo 4g battery will fit our devices?

i just ordered a evo 4g slim 2000mah for $14, its same dimensions as stock, so i am assuming it should fit? maybe minor trim issues?

ps it also stated it would also fit incredible/hero/and tp2

[G2 and Desire Z Accessories] C.Flat:
First day with my new Mugen 1800 mah battery and... %$#$! This makes me suspect my stock battery may have some... problems. I'm at 91% after 5 hours of moderate usage (wifi on for 4 out of the 5 hours). My stock battery would be in the 60s at this point.
