Source for spare battery - JASJAR, XDA Exec, MDA Pro Accessories

Yesterday I used my JJ in the way I use my Treo 650, as a mixed PDA and cell/mobile phone. Now my Treo battery gives me 2/3 days of use (it is on 24 hrs a day) while my JJ after about 15 hours was down to 25% battery capacity (and I did not use WiFi but used BT for 10 hours, about 2 hours of ebook reading and the usual PIM/sync activities and about 20 minutes of calls). With this sort of battery usage I really need a spare battery (I do have a portable USB based batery charger that I could use as a fallback).
Where can I get a spare battery from? Expansys claim they will have some around 2nd week in December!
Thanks

To Jah,
Mugen Power will launch the latest extended battery for the JJ. Pls keep on watching this forum for further information.

Any realistic idea when? I can hold off for a short while...
p.s. awful web page, seriously - Contents of http://www.unifirm.com/pda.htm means nothing to a normal user.
Use the device names and capacities - "XDA Exec, 1750MAh" sounds a lot better than "HLI-X3SL"...
EDIT: And I can't even click on the things? Useless.

Please make it a higher capacity one, double or triple the current capacity would be nice.
A charger to come with it is also appreciated. I'll grab it as soon as it comes out.

A battery charger is definitly a must have, The xda takes too long to charge because of it's mini usb connector, even when connected to an AC socket. I wouldn't bother buying a spare battery cos with the current charging options It will just take too long to charge the batteries up.
Besides, one can only charge a battery at a time since there isn't a dock with a spare battery charger or a standalone battery charger for the htc universal.
A fast charger for the battery alone would be excellent.
Got mugen batteries for all the pocket pcs I've ever owned and they rock.
Hope to get some feedback from mugen on developing a fast charger, I recon alot of htc universal users will be very interested

In this case HP teach!!!!
Before JJ I had a HP6515. I've bought spare high capacity battery and I've received it with it's separate charger who connects to the main cradke with a bypass. FANTASTIC!!!
See it @ http://www.ipaqchoice.com/ProductInfo.ASPX?Cat=6&ID=1039
CIAO!

YES YES YES!!! Where on earth is the battery charger???? It should have been thought of long ago? :roll:

[Q] High Capacity Battery!

Any one know where can i get a High Miliamp ( ex 2500Ma) like battery for my Xda Atom Exec. ? I found one for my previous Imate Jamin worked fine.
hi, i think i found 1 in ebay, 3500mah
might cause problems due to excessive heat
i've read from one of the post that extended battery create much heat and leaves our dear love atoms into unstable state, possible permanent damage. let us know how it turns out...?
it's definitely good bye, to my metal casing/protector, if this extended battery is any good...

sorry double posted somehow.
I use MUGEN type and that has been very good. No over heating and lasts whole day when using GPS software when the normal battery would be dead in 2-3 hours. here is one site that sells on the web.

In fact the same battery and cover fits both the standard atom and the Atom Life.....probably the Atom Exec as well.
50 quid + delivery,u must be joking go to batterytrader much cheaper

I bought one just a month ago and so far cero problems, no heating, no leaking, only longer power...My previous battery (the original) could only mantain energy for 1 day without using the pda, but if I turned on wifi it only lasted 1 hour.
So I use to mantain my atom exec connected at my car and at my work, now since I bought this new battery 3500ma, I havent connected it to my car, and havent dropped charge below 50% in a month! because every day I connect it to my PC at work but after using the device for the weekend in a normal fashion I only reconnect it on Monday.
Only drawback is the battery is bigger double sized so it came with a different back cover.
I have paid 25 dollars at ebay and I am happy with it.

Hi all,,
I'm using a rechargeable Lithium-Polymer battery from the company Cameron Sino Technology... It has a capacity of 3500mAh and 3,7 V...
I just bought it 3 weeks before and charges only 3 times in very low usage. (a few phone calls, a few e-mail). And app. 7 days I can use it.
But it think, I can use it with my normal usage 3 or 4 days, not more...
I'm very happy
regards
Wow, 3500 mAh? Imagine will it's works on my O2 XDA Atom Black than just 1530 mAh!
How much you paid for that 3500mAh battery ?
I'm interesting too it could be so nice...
I have done some efforts regarding battery capacity measurement
Just lookup this thread: http://forum.xda-developers.com/showthread.php?p=5558383#post5558383

Extended Battery that is not bulkier? (can use original battery door)

hi does anyone know of an actual battery that has more capacity but does not require a bulkier battery door?
and most importantly, that it DOES give you more battery life?
because i once bought a 2000MaH battery for my HTC TP2 on ebay and that was the biggest scam i fell for, the stupid battery gave approximately the exact same battery life as the old battery... which was 1500MaH

Yeah the batteries that do not require a bigger back door are all going to perform the same oem or worse. So you can get a cheap charger and and extra oem battery and do that,or say **** it and get the big ass battery

ahhh the eternal quest for the holy grail of batteries. nope, it's not possible. not until battery technology improves. If it was possible to have a better performing battery that was the same size HTC would of put it in their to begin with. check out batteryboss.org for proof.

I did check it out! What's wrong with the 2150mAH TP2 battery as an option? I ordered one. Thanks for the link.
Here's one: Mugen Power Extended Battery 1800mAh for HTC Evo 4G
However, the reality is that Manufacturer claims a 20% improvement in battery life. Depending on your use that may or may not be significant enough. I'm just running stock battery w/ custom ROM (Damage Control) and some system tweaks which significantly improved battery life (errr, at least resulted in less battery drain

The "1800mAh" Mugen tested identical to the 1500mAh OEM battery.. save your money. http://batteryboss.org/results/NewMugen1800mAh_vs_NewOEM1500mAh.png
IMO the best option is to tweak your settings.. Im getting as much as 30 hours out of my OEM 1500 battery now. I also have 3 spare
batteries in case I ever need more juice. they are quite small and fit in a wallet fine. i've yet to actually need one. You could also try
this, which was told to me by an HTC Rep (and it for real almost tripled my battery life!)
"To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well."
you only need to do it once, and then again each time you flash a new ROM or do an OTA update.
did this method of turning the phone on and off and charging the battery for another hour improve battery life for anyone?

30 hours? you joking right?
If you getting that much why in the world would you have the need for an extra battery let alone three?
I call BS
That's hardly BS.
I easily get 30+ hours out of a single charge.
Right now im at 22 hours with ~45% battery life on stock 1500mAh.
It's a rip-off to get an extended battery because they don't perform as well..
I am waiting on a 1750mAh spare battery that fits with the standard back plate. If it works well, I will advise.
what is your up time though. i have an 3500mah extended battery and i don't get 30 hours still

I keep 4g on
I keep data always enabled too.
Do you?
I get over 9 Hours with BT, and data on all day. I have a task manager that shuts things down every 30 mins "IGNORE LIST messages, gv dialer, clock, task manager" Without it I was getting 4 hours. I make calls and surf the web and watch my porn clips during the day, so it does get used. I sent for the 1750 yesterday so I will update this after I get it that thing going. And the new batterys do have to be charged and discharge like 20 times before the hold a charge as well as they say it can.. Batterys on ebay=joke, buy the name brand ones. I used to make r/c battery packs and they have a peak run time in life, and its not the first time you charge them. It takes time..
I went to eBay and bought the "HTC EVO 4G BATTERY 1800+Dock USB CHGR SPRINT TOUCH PRO2" from vendor Chichitec. Vendor is located in California, so no sketchy chinese vendor, high ratings and fast delivery.
I haven't really timed how much more usage I'm getting with this new battery, but it does last longer, trust me.
The separate wall charger also seems to charge the OEM battery better than just by using the usb cable on the phone.
Not a bad deal for $19.98 at your door.

I get anywhere from 20-40 hours on a single charge(OEM battery) depending on my usage running Damage Control 3.2.3 with netarchy's 3.7.5 kernel, setCPU and Advanced Task Manager. I have setcpu keep the CPU @ 245mhz when the screen is off and 245mhz-1113mhz(on demand) when the screen is on.
I also use Advanced Task Manager($0.99) to kill out the programs I'm using with a widget/button. Whenever I'm done using the device I quickly hit the kill button(which doesn't kill the normal essentials) and shut the screen off which down-clocks the proc to 245mhz.
Today for instance:
-unplugged at 07:00
-GPS on, Wifi Off unless needed, 4G Off, Bluetooth On during travel
-beautiful widgets updating weather every hour via cell triangulation
-stock weather updating every hour
-used for slacker via the AUX jack for 45mins-1hr on the way to work
-1 bluetooth call in between listening to slacker on the car
-about 10-15 calls today while at work
-about 10 emails came in and I read them
-browsed web for prob 20mins during lunch on office wifi
-used for slacker via the AUX jack for 45mins-1hr on the way home
-rebooted device
-made 1 non-bluetooth call, sent a few text messages, and then posted this
I'm now at 61% battery remaining and probably won't charge this until lunch or on the way home from work tomorrow. I would give my up time vs awake time but I restarted the phone an hour ago so those figures aren't there anymore.
So, BS? I think not.
I have read what batteryboss has said but I can tell you I get 3-4 hours longer use from my 2000Mah battery. Now I am seeing a big drop off with Froyo but it is on all my batteries, even the OEM.

I hear that, I probably lost 20% or more with froyo and immediately reverted back to my DC 3.2.3 build.

Portable Chargers

Hi,
I wasn't sure where to put this so feel free to move it where it need be.
I recently got a new HD7 (love it!!! ) but unfortunately the battery leaves a little to be desired, it only has a 1230mAh battery. This spring i need to survive a 15hr bus ride to Florida with no plugs in site for the whole time. So my question is who has a portable charger they like and or one that will help me last 15hr? I am looking at the Power Mat portable 2x which should give me almost 7 full charges on it 7800mAh but I am game for anything that will give me lots of power.
Thanks!

well.... I picked up the powermat, I have to admit its incredible..... its a great accessory for anyone on the go.
That non-standard batteries are ugly!
I have APC UPB10 - portable USB-battery. It is very compact and has capacity nearly 10x more than standard HTC HD7 battery. This thing charges all my gadgets when I am not at home. And I've never been in situation when my portable charger was totally run out of power.

External Batteries

I was just wondering whether external batteries are generally quite reliable, and if so what the best brands are to go for? I am looking for a relatively powerful one - I am not afraid of a little bit of cost, but obviously I don't want to spend masses.
Thanks
Ive got a New Trent and its well built and reliable. The 11000mAH will last you for several days. Have a look on Amazon.
I have a "Just Mobile Pro" or something like that.
4400mAh with 1000mA output.
But the EasyAcc 5600mAh (which I don't have) does sound better and cheaper (on Amazon).
Second new trents 11000mah one that thing is a beast

Thanks not heard of New Trent before. Looks good. Can you confirm it's output charging current though? I can't find the spec on it anywhere. I'm assuming it's the full 1A, as it says it can charge an iPad, but could you please confirm? Looks like I'll be needing one!

Hah! Good thing I didn't have a mouthful of soda there...
Good thing to remember with external battery packs is that during usage some of the charge goes to charging the battery while some is lost in heat. I think I read some where its normaly 30-40%. So for example a 11000mah battery will give you some where near 6600mah of charge so about 3 and half charges of the HTC One X.
I'm considering either the:
TeckNetĀ® iEP387 7000mAh Dual-Port 2.1Amp Output Universal USB Battery Bank
http://www.amazon.co.uk/gp/product/...&pf_rd_t=101&pf_rd_p=467128533&pf_rd_i=468294

The heat loss is inevitable but the capacity should be unchanged.
What the heat loss means is that you need more than 11000mAh to charge up the full 11000mAh battery due to the losses.
The tecknet is very good value. I am considering it at the moment

Yes but I'm talking about in the other direction. So once you have 11000mAh in the device and you charge a device that take 1800mAh you will actually use aprox 2520mAh in doing so. My numbers and calculations maybe a little flawed but my point is that you cant do a simple 11000 / 1800 = 6.1 charges as you need to take into account heat loss which is around 30 - 40% (so I read on one of the amazon reviews)
Either way both devices are nice and cost quite reasonable.

My numbers and calculations maybe a little flawed but my point is that you cant do a simple 11000 / 1800 = 6.1 charges as you need to take into account heat loss which is around 30 - 40% (so I read on one of the amazon reviews)
Either way both devices are nice and cost quite reasonable.

Ah yes of course. Did not realise you were talking about the other way round charger>>phone
Not sure how efficient but if say 10% loss, we still get around 5 times charge with a 11000mAh batt. to a One X.
I am leaning towards the 7000mAh. Not sure if I need it or not...

Also don't forgot not to simply divide the battery pack's capacity by your phone's battery capacity to see how many times it will charge, unless you are charging it with the phone turned off.
With the phone on it is obviously using the usual amount for running the phone, whilst it is being charged. Add the current being drawn for keeping the phone running (say 250mA when awake) for the time it takes to charge (for me 2 hours) and you are looking at 500mAH. Add that to the capacity of your phone battery before dividing it by the capacity of your battery pack to figure out how many charges you'll get from it. Figures used are just for example purposes. Use a current widget if you want to know how much your phone is using.
Plus like a phone's battery, a new battery pack will take several charge cycles to reach full performance. Where as with a phone's battery which only takes about 2 weeks (charging it every day), a battery pack will take that much longer to get the full performance out of, as you wont likely be charging it more than once a week/month.
And then there's the battery indicators. These New Trent ones look sensible, but I once purchased a Proporta Turbocharger 5000mAHr unit. It had three blue LED battery status lights that were always on if charging. If you looked directly at them they'd burn your retinas out your skull. They could be seen from space. Stupidly and comically bright. They HAD to eat into some of the capacity.
Copper losses over the cable at the distances involved in your average charging cable will be negligible. If you really want to reduce it, don't use those silly skinny retracting yo-yo charging cable things that some of them come with. Use a decent quality USB to microUSB cable. The higher the guage of the cable and quality of copper, the less volt-drop there is. I keep a good few of these kicking about at home as they are well made but not too costly, and come with a nice cable tidy clasp...http://www.ebay.co.uk/itm/GENUINE-NOKIA-CA-101-CA101-USB-DATA-CABLE-LEAD-5230-/140579882085?pt=UK_MobilePhones_MobilePhoneAccesories_MobilePhoneDataCables_JN&hash=item20bb36c465

the last link has the same capacity as the 2nd last but it is way cheaper.. is it safe?

here u go..
posted this in another thread..
cheers..

Just got my Anker 1800 mAh batteries. Now what?

I've read a few mixed opinions on draining the battery fully to ensure maximum charge potential or whatever. Can someone tell me what to do now that I have the dang things?
Also, I bought two, so if anyone wants to buy one send me a PM.
uhh full drain on a li-ion is BAD! just charge em and use em ..
I've read to get the best long term life out of your battery to try and keep it between 50% and 90%. No need to ever fully discharge or charge.

I have been running mine for about 4 months now and its great. I can actually get a full day of heavy usage without it being dead before I get home.
My stock battery usually die in middle of the day if I use it frequently with wifi on all the time
Have been wanting to buy a new one. Any suggestion?
I bought two also, and they came with a cool external charger [for the batteries only]
I recommend keeping the 2nd battery, and always have one charged and ready to go. Great for long trips, as the gps seems to be a huge battery pig.
I'm very pleased with these batteries.
