On the battery pack cases (ibison, etc) Is there a way to access the battery of the case
first before accessing the HTC battery?
For example if you put in a fully charged HTC one and then turn on the battery pack will it draw
from the battery pack or will it draw directly from the HTC one and then the battery
pack recharges the phone?
I am hoping that you can run directly from the battery pack case.

They're simply a power source. Instead of a wall to plug into the phone is plugged into the case/pack. I see a lot of them have a switch you press to close the circuit and start charging the phone. To do what you are suggesting I would assume a kernel edit or hard mod would be required. I may be wrong though.

It would take some kernel mod to draw from external only. It's doable in the Linux roots, I just have never seen anyone do such a thing on any of the devices I've owned. I'd also be a little leery about whether or not an external case could reliably provide enough voltage to run the phone, but if it works, it would be pretty neat.
You'd also face the problem of the kernel being unable to detect the external battery's capacity and switch over to internal power + charging, so you'd best have a watchful eye!
great

If this can be done the internal battery will virtually remain brand new. That would be a great accomplishment.
The question is, is it doable..................

No, not really. Unless you could fully d/c the battery, you'd still get at least some wear, and leaving a battery idle doesn't preserve it in the slightest. If you want to preserve a battery, drop the charge to 40% and leave it in a cool, dry refrigerator. Your battery is still going to suffer all of the temperature-related wear and tear which is what helps send most batteries to the grave.

What about this 8800mAH (by WINTOP) for the Dopod 900, huh?

Well, I suppose it'll work for all the Universal variants, right?
:lol:
Also www.batteryupgrade.com are now selling Exec batteries. Have ordered one will report when I receive it.
Charging an extra battery is going to be a pain Hope there's gonna be some 3rd party cradle that allows charging of an extra battery like with the older devices.

just bought a apre battery from ebay too...cost 15.00 inc P&P. Better than 25.00 ive seen elsewhere.
agree 'bout the cradle though. found a cradle but doesn't have a spare place for charging the battery too.
BTW also beware.... syncing daily with usb cable part charges the batery and will cause memory effect...
use blutooth instead.

Do Lithium Ions sufer from memory effect?
I presume that's hat the battery is?
No, LiON batterys do not have memory. Unlike NiCad's which do.
General rule for LiON batts is to keep em cooked on charge, rather than flat out for any length of time, deep discharges can create bubbles on the cells apparently!
Although some latops have conflicting LiON advice, stating that you shouldnt leave the batt on mains for more than a week at a time.
In addition there's text in the "newer" manuals for phones and PDAs stating that the LiON batts wont have "full" capability until theyve had a few deep discharge cycles.
So my advice is keep the thing on charge at all times, but dont worry about running it right down from time to time, but be sure to get it back on charge soon after a deep discharge.
I have killed a perfectly good ipaq3630 batt by leaving the device for 6months off charge. Conversly I have no evidence to suggest detrimental performance from my Eten-P700 which is hardl 8) y ever off charge.
Last point, I believe the later devices dont actually full discharge, I suspect they "hard set" off whilst a little juice remains. Unlike the older Ipaqs etc which drain to the last drop (bubble?)

Hello again. How many cycles or at least how long does it extend the built-in battery. This sound very enticing especially on long trips.
RE
Hi cktlcmd,
Base on calculation its about 5 full charges although I have not counted it since I'll plug the battery into my set whenever I'm out surfing at hotspots
One thing to note is that if you've the phone turn on, bt turn on and wifi also turn on then the power consumption is greater than the external bat can supply since USB DC current supply is much lower than the AC adaptor of 1A DC
You'll see tha battery level drop, however, without the ext battery you cab bet that the battery level will drop faster.
Thanks FOSA. This charger is on my wish list now.
RE
Hi cktlcmd,
FYI, if you intend to buy this battery do take note that you also have to purchase the intelligent cable (with a built-in chip) unless it comes with the battery. Its a proprietary cable with a proprietary port on one end and a 5-pin mini USB port on the other end to connet to the Universal.
The output port of the battery is NOT a standard USB port.

In truth though, you could hardly describe that as a battery, unless I'm being taken to the wrong page each time?
I'd describe that as more of a battery extender. A good idea nonetheless, I used to use a little 4xAA one with the JAM... good if you're in the arsehole of nowhere...
Hey, wonder if it's pin and power compatible, still got it along with a holder and other accessories...
Just got it in the mail - had pre-ordered it from Mobile Fun about two weeks ago.
Someone else posted pics already, but couldn't find the thread - here are my own.
Note, the case acts as a battery charger, and starts delivery electricity as soon as you put the phone in. There is no switch on it. I'll have to see in the coming days, but it looks like it's necessary to only put the pack on when you need it.
Things I fear but may be unfounded:
it won't be practical to leave the case on at all times
need an extra charger to charge them seperatly and efficiently
I hope I'm wrong, and hope I can just keep it on at all times, and charge both the battery and phone at the same time using one charger.
Thanks to Eiraku posting in this thread, I was able to find the original thread for this battery pack:
http://forum.xda-developers.com/showthread.php?t=1110441
Mods please feel free to merge subjects.
Here are more pics
Isnt it a bit harmful to always have the battery at 100% charge level and even have trickle charge, they should have implemented a switch or at least some control mechanism to have it start charging only at around 50-80%
I think you're right, and indeed, the case start charging the phone even if the phone's battery is full.
From the manual:
"When not in use, remove your phone from the power pack."
Kinda of a let down. But I'm still happy to have it for my asian trip at the end of the week - electricity will sometimes be a luxury.
The purpose of this case is kinda moot if it does not have a switch and cant be kept in use.
Thanxs for the pics...I ordered this case from expansys a month ago and am still waiting on it to ship. Looks great.
So what is the purpose of this button

There IS no such button. Only the battery tester button (which is useless).
Cost cutting, Samsung? You delayed the battery pack to remove that freaking power toggle?
Personally I can't wait for PowerSkin to come up with something better (OR that urban legend official 2000mah internal extended battery with new cover to come out). But as of rite now, I'll take what I can get.
To OP: thanks for the nice pics. They're much better than mine anyway. And welcome to the club!
There is indeed a button as indicated on the pic you have there, but on mine, it doesn't quite look like that. There is no marking on it or next to it - it's a simple push button which function is to indicate battery level. When you push it, the battery indicator will light up green, blue or red according to its energy level.
The pic you have may be a prototype or maybe a different version other people are going to get?
Without power toggle
I will cancel the order
Guys,
Surely just because there is more power available behind the standard battery, doesn't mean the phone will suddenly start drawing more power from it?. A car doesn't consume more petrol when the tank is full... how would this be any different to putting a ...say 2000 mAH battery (if it becomes available) instead of the original OEM battery??..
More mAH added by the sleeve should give extra run time...
Riz
I'm no electrician, but I like the full tank analogy.
Imagine the tank is full, but let's say I keep pouring fuel in the tank while the engine is running ... kinda of a waste as the extra fuel will spill - not to mention the danger.
So the question here, if the energy or extra energy delivered by the battery isn't being consumed, is it wasted? Is there danger if there is "spillage" in the form of heat? This phone can already get incredibly hot it you use it as a GPS for an extended period of time.
I'm still concerned about what the manual says about removing the pack when unused.
Actually, I have all confidence that this is a "smart" charger, in the sense that it will only top up the internal battery as necessary.
Using it as an "extender", I have no issues getting 3-4h extra on really heavy, constant screen on 3g surfing. It didn't even get hot at all, so power was NOT needlessly drained.
As a "charger", I got from 6% to about 42% from a fully charged extpack. In this config, the case did get quite warm, which indicated that it was quickly expending its reserves to charge the SGS2.
For a 1300-ish mah pack, this is more then consistant performance in my book, from my experinces from owning multiple iPhone 4 batt cases.
Only issue is with the lack of power toggle, there's much less flexibility allowed. You can't choose to keep the extpack as an emergency reserve UNLESS you take it out.
Also, it only takes in 700ma (the Samsung charger is rated at 750) and gives out 650ma, which means that in the event that you are charging a fully depleted extpack and say a 50% power left SGS2, the charging of the extpack will take FOREVER (phone first, then case).
But charging the SGS2 takes forever to begin with, so...
I'm no electrician myself...
But... about the car engine.... there are fuel governor controllers which only allow enough fuel as is needed to enter the combustion chamber...
but.... we talk of batteries... the way electrons work.... my understanding is...
flow of electrons is decided by the potential differnece available for them to travel across.. the higher the potential difference... the more electrons would flow...
So, lets say... the SGS2 has a power consumption of 100 milli-amps (based on whatver the volgtae rating is).... a 100 mah battery would run it for 1 hour... a 500 mah battery would run it for 5 and so on....
Adding a battery in parallel.... would not increase the power consumption from the original spec'd power requirement of 100 milli-amps... it'll just increase the total amperes available to run the device... so.... more ampere-hours available... hence longer hours available to run the phone
Quite simply, it is similar to leaving your phone connected to the charger... I'm sure most of do this every night for the duration of the night....
leave the phone connected to the charger... i.e.
Ars Technica has a good article on batteries. It basically says this thing should have a power button!
http://arstechnica.com/gadgets/news...-is-the-best-way-to-use-an-li-ion-battery.ars
"On the other end of the spectrum, keeping a Li-ion battery fully charged is not good for it either. This isn't because Li-ion batteries can get "overcharged" (something that people used to worry about in The Olden Days of portable computers), but a Li-ion battery that doesn't get used will suffer from capacity loss, meaning that it won't be able to hold as much charge and power your gadgets for as long. Extremely shallow discharges of only a couple percent are also not enough to keep a Li-ion battery in practice, so if you're going to pull the plug, let the battery run down for a little bit. "
I believe that the phone, like the iphone, and most laptops, don't fully throttle their devices on battery. So maybe when it's plugged in it would use more power thinking that it's tethered into the wall. I had that issue with my iPhone 4. I had a battery case for it. The phone itself could last me say, 6 hours on its 1400 mah battery. When I put the 2000 mah battery back on it, before the battery pack died, was only 5 hours. So my phone consumed 2000 mah in 5 hours, while on the internal (smaller battery) it consumed it within 6 hours. Hmm... That's not right. So, then I investigated it and while plugged in the phone went into "performance mode"
Is that at all possible on THIS phone as well? hehe.
I'm not big on the whole battery switch, so, I'm skipping this case. I wrote power skin and let's see if they release one for the SGSII. I'd love it if they did

There's also the fact that a battery directly wired to the device will always perform better per mah vs an externally mounted battery. Heat loss through the external connector, yada yada.
If you're afraid of "performance mode" (which I also think some phones have), just use SetCPU to override it, like I do.
I'm hoping PowerSkin comes up with something soon too - as a case, the ExtPack has really crappy all round protection, especially on the front (getting the SGP Glas protector because of this).
i'd go for the case only without the battery.... it looks quite dangerous...
Im looking for a Battery Case for my HOX.
I can see all of them, or most of them, got an on/off button. Why?
As an extended battery, I would assume both the case and the phones battery, got a connection that would make them like one battery...
When I buy a case, will I be able to have the case on at all times? And if I then charge via the phones USB port, will be case charge aswell? And the other way?
Thanks!

No I don't think the batteries combine together to create one large battery. A battery case is basically a power source, where your phone recharges from, and the amount of mA is just an indicator of it's capacity. The on/off button is used when you want to recharge, or want to stop recharging. Cases are rechargable.
much signau
Then I will be able to always have the case on, and just charge the case. My phone will then, hopefully, most of the time, have full battery.
It will be like always having my phone in the charger. Will that hurt my battery?
Hello everybody, first post on XDA!
I am planning to mod my Nexus 5 battery. Considering that the dimension of the original battery is 57mm*60mm, I planned to buy 4 Sanyo 3,7V 840mAh and connecting them in parallel. I would like to post links but as a newbie I am not allowed to do so.
These are 14mm in diameter and 50mm long, meaning that 4 of them would be packed in 56mm*50mm, with 10 extra free mm where I can comfortably fit the "charging board" that I can unsolder from the old original battery. The problem here is that the charging board will probably have more than 2 pins, the others being for temperature and data. How can I deal with them? I haven't teared my battery yet, so I cannot see how the chip really looks like. Does someone know whether the data pins end up in the circuitry or are they somehow connected to the battery itself? Because in this latter case I would really have no idea how to deal with these extra pins...
In addition how will the circuitry and the phone itself deal with the increased capacity? Should I tell the phone the capacity has changed or will it auto adapt? I have read tons of posts on this topic, all saying different things...
Certainly that will increase the phone thickness and I plan on 3D printing a custom designed back-cover. Luckily the original 3D model is downloadable from GrabCAD for free, that is a good starting point. What material would you suggest me to print it in? PLA, ABS, Nylon?
Furthermore, I am planning to add a nerdy solar cell 4v, 35mA that will certainly do basically nothing except help in real emergency charging the phone while off, but it will give an awesomly nerdy look. The solar cell I am talking about is 32mm*39mm and would perfectly fit on the right of the camera.
I could fit a 100mA solar panel, or avoid the battery mod at all and just fit 5 of those solar panel for a summed max current of 175mA...
I plan charging the battery with direct connection of the solar panel to it through a diod. The only thing that worries me is that while 35mA are less than what the phone draws during standby, the battery indicator will never go crazy seing the battery tension growing while no charger is plugged in. On the other hand, higher currents, will actually be able to actively recharge the phone creating confusion to the phone that would not be able to realize what is going on. To avoid that I should connect the solar panels to the usb charging port. That would put the phone into charging mode and thus in a energy hungry more that could again cause battery to drain instead of charging or anyway to charge incredibly slow.
If someone is interested in this project and has suggestions of any kind I will appreciate and I will share the results.

Firstly I would scrape the idea of a solar cell, it's going to generate very very little power especially since its going to be pointed down. Also that 175mA is probably going to be something smaller in the real world even under ideal condition it'll be almost impossible to generate that. Now for the batteries you would like to put into your phone, you have to open up your phone or find dimensions and see how everything fits together. Sometimes their will be some space around the battery and this is put for several safety reasons, so I do not recommend filling up the space if you go ahead with this replacement. This could lead to battery overheating which could cause it to leak and cause a short and destroy your phone. At the end of the day I really wouldn't recommend anything attempt this unless you really know what you're doing and the risks involved with doing this. I don't feel the increase in battery life would offset the risk factor of attempting this. Also I should mention that when you solder that it's going to be very fine and sensitive solder work, there are many things on that board that will be heat sensitive and power sensitive so using something like a $50 Weller wouldn't be sufficient.

What Brand and model do you use?
My concern is internal battery life span. I think that power case works just like you would keep your phone connected to the charger all the time. When battery drop by 1% it will be charged and all that again and again. Can it be controlled by app that for example phone won't start charging battery before will drop to 30% and then will stop charging at let's say 95%. Can it be done on unmodified system or it would need custom kernel to support that?
