I'm not a programmer but I would like to help if I can. Picked up my MoPho 3 weeks ago, rooted it, and did a couple buildprop tweaks but nothing else. Haven't unlocked it yet, either. I would like to flash a different rom and/or kernel but want to do more reading first. I also need to get the right sbf and such, too. Currently system version 45.3.6.MB855.sprint.en.us; Android 2.3.4; Baseband N_01.28.07R; Webtop WT-1.2.0-160; Kernel 2.6.32.9dnt648@fl36bid2 #2; Build 4.5.1A-1SUN-198.6

Not sure if I can say much on here but try to move the signal to Verizon.

I saw on the zumocast advert on the motorola website the photon was sporting the LTE icon. Maybe a minor error with one of the artists or maybe a hint...

If you're about to ask me if I've considered an ssd instead, know this. I may be an idiot, but I'm not that stupid. My IQ may be around 30 or so, but It's just high enough for me to figure out that an ssd is a much better option than an hdd. Jesus christ, stop asking this question already. The reason I've opted to put in an hdd instead of an ssd is because of cost. It cost me about $50 to for a 750GB hdd. An ssd with the same capacity will cost an arm and a leg. Go ahead and look that up.

So, please, if you're going to suggest I use an ssd, consider reading the above paragraph. And if you're going to email me telling me what an idiot I am for using an hdd instead of an ssd (like that turd a couple days ago), then also consider pushing the donate button right below my name so I have enough money to buy an ssd with comparative capacity. Goodness...

People, just because this is the internet doesn't mean everyone else beside you have an IQ of a potato. Get over yourself already.

****************************************************************************************************************************

I'm making a new thread because this is an entirely different mod than the other one.

So, I've added 2 more battery cells parallel to the other ones, doubling the capacity while maintaining the voltage. in addition, I've also added a 750 GB HDD.

Unlike the other mod, which suffered no deformation, there is a little bit of deformation in this mod. I can still close the netbook form. And if you look, you can see the curvature of the keyboard dock. It's not very noticeable, but if you know it's there you can definitely see it. Here are the pictures. I am currently testing out the battery capacity to see if it's really doubled like it's suppose to. We'll see, I guess.

By the way, while I am very happy with my result, despite the slight deformity to my dock, I definitely recommend against this for anyone else.
[Eee Pad Transformer General] goodintentions:
Speaking of which, how do I recalibrate the battery indicator? Looks like it's dropping at exactly the same speed as before.
[Eee Pad Transformer General] maciek82:
I'm new to tablets, but on my Android phone you can run a app like battery calibration and it deletes batterystat.bin file.

Btw, cool mods I would be really interested in double battery.
[Eee Pad Transformer General] goodintentions:
It only affects the tablet battery. I can't get a definite answer from all my searches how to recalibrate the dock battery.
[Eee Pad Transformer General] asdfuogh:
Aw, the deformation is a no in my book, but I think the mods themselves are awesome. If I tried this, I think I'd go for more batteries because I can't find enough stuff to fill my 32g usd cards anyway.. (or a secret compartment storing unmentionables).
[Eee Pad Transformer General] maciek82:
Ahhh.... Yes forgot about dock battery. Don't own one :D
[Eee Pad Transformer General] goodintentions:
I don't blame you. The deformation is hardly noticeable, but it is there. I'm actually happy with this setup. The slight deformation doesn't bother me. As long as I can still close the netbook form.

Now, if only I could find a way to calibrate the dock battery.
[Eee Pad Transformer General] fliparsenal:
Impressive work! Let us know how long the battery lasts.
[Eee Pad Transformer General] goodintentions:
Well, I gotta figure out a way to recalibrate the dock battery first. It's dropping at exactly the same rate as when I only had 2 cells. Can't freakin' figure out how to do this.
[Eee Pad Transformer General] asdfuogh:
By the way, I think I saw that you said your method is more refined and less risky now in another thread; is the method different, or have you refined your skills? If the method is different, could you post a tutorial? I think I might attempt it after I find out if I got into any good grad programs.. (because then I will know whether or not I will have some amount of money to burn for no damn reason :P).
[Eee Pad Transformer General] goodintentions:
Both, actually. Before, I was both stumbling around blind and doing things in not so efficient and safe way. My soldering skills have improved greatly and I have also refined my procedure to involve no risk at all. It's all in the wrist, man.

Uh... no. This mod voids your warranty. I will take my methods with me to the grave.

PS - Isn't it obvious from the photos?

Added by edit.

Ok, my conscience got the better of me. There is something I left out of the photos. A key ingredient to making this whole mod work. Without this very simple but critical thing that is covered up by other components in the dock, the mod might as well be a piece of brick. It took thousands of hours and millions of dollars of research to figure out this one small piece of modification to make the whole thing work. My dock was sitting there for almost a month dead before I brought it back to life with this thing I'm speaking of.

In other words, don't try this. Trust me, you'll regret it not knowing what this thing I'm talking about is. It took me a whole month to figure out this thing. Thinking back, my goodness, the solution was so simple. And yet it took me a whole month to solve it.

Added by edit again.

I just figured out how to make the deformation go away. Damn, why didn't I think of this before. I'm too lazy now to open it up and apply the fix.
[Eee Pad Transformer General] ratindahat:
Are you not worried about charging two separate battery cells without a load balancing charger? At least from the RC world, this is a big negative. Fire can be no fun.
[Eee Pad Transformer General] goodintentions:
Exactly why I just took it apart again to redo my setup. Will update on my progress later.
[Eee Pad Transformer General] goodintentions:
Ho ho ho, just figured out a safe way to connect the bats. Too late now. Will do it tomorrow.
[Eee Pad Transformer General] lrissman:
Exactly right, lion/lipo batteries need to be balanced in charge otherwise you will burn out the batteries and in extreme cases, BURN the batteries.

Having said that, many/most of the lipo batteries I have worked with in electronics have balancing circuits per "cell" so in reality you can simply add them like any battery and they take care of themselves. If lipo batteries were purchased without that circuit, then they are very cheap to buy and add as well.

I havent cracked the transformer, and dont plan to because the stock battery life is plenty for me; however, I have increased the battery capacity on several laptops, and other types of devices, and the first key is to ensure the cells are balanced before connecting them together, then ensuring you have a balancing circuit to EACH cell otherwise over time they will come out of balance (normal use and internal resistance). Once you have done those two things, you can connect them and use them.

Now, the other point is the meters. I have no idea about the transformer but most battery meters work simply on the voltage on the batteries and assume the discharge in a linear fashion. This is rarely true for batteries, but it is simple, cheap and gives you an idea about how much power you have left. Sometimes this is error is covered by software that "maps" the battery discharge rate and gives you a "real" battery left level. So to the point of all that paragraph, once you balance the batteries, connect them and run through a few full charge/discharge cycles, you will likely find that the meter will catch up.

A point of caution, the word "cell" does not refer to a nicely packaged lipo battery with two wires. A cell is a single constructed unit that is usually 3.7v in the lipo world (different chemistries of batteries will have different voltages). If you added a pair of 3.7v (1s1p) batteries in parellel with a pair of 7v batteries (2s1p) you could really confuse the battery meters. :)

Enjoy the mod, I love reading about them..

Interesting stuff, makes me wish I had the tools (especially a soldering iron) and more desk space, just to see what experiments could be had with this device.
[Eee Pad Transformer General] goodintentions:
I just redid the mod. Unfortunately, it was 3am and I forgot to take pictures before I closed up the dock. But basically what I did was charged both batteries up to 100% and connected them in parallel as is with their balancing circuits. Before, I took the cells out and added them to the circuit of the other one. This time I kept the circuits and added the circuits together.

It seems to work. The new battery pack is recognized. We'll see what happens later.

Here is a picture to give you an idea.

[Eee Pad Transformer General] goodintentions:
Why?

I'd rather have more storage.
[Eee Pad Transformer General] yalkowni:
If I were to send you my dock and money to buy supplies and labor
[Eee Pad Transformer General] goodintentions:
I'll add in a hard drive, but that's as far as I will go. When it comes to extra battery or even a bigger battery pack instead of combining the batteries, I won't do it. I'm already poor enough. I don't need someone suing the hell out of me for whatever reason. I'm drawing the line right here. I will still put in a 500 or 750 gb hdd with an on/off switch for people. But if they want bigger batteries, they are on their own.

Update on this. My mod seemed to work. I had it on full brightness since last night. Seems to last much longer. I'll do a complete test at the end of the week... that is if I survived until then. Gotta go to see a musical right now with the better half. Let see if I can sit through it withough shooting myself in the head.

Yeah, the weight is definitely noticeable now.
[Eee Pad Transformer General] goodintentions:
Ok, I really really need to know how to recalibrate the dock battery indicator. This is ridiculous. When the dock battery indicator is down to 3%, I took it out and tested. It's actually 54%. So, my mod is working. I've doubled up the battery. But the damn tablet isn't calibrated to it. So, when it thinks it's at 3%, it stops using the dock battery.

How do I tell the TF to recalibrate? What can I do to make it recognize that there's still quite a bit of juice left in there? Please help.

Added by edit.

And no, I'm not seeking attention. I genuinely need to know how to recalibrate the TF dock bat indicator. I've doubled up the battery capacity. Now, I need the TF to recognize that.

[Eee Pad Transformer General] goodintentions:
Ok, so I just sat down and discharged all the individual series cells down to 3% exactly. Connected them to the balance circuit. Hooked the setup to the TF and the TF read 5%. I'm guessing what was happening before was that the cells were not balanced. I tried to approach the balancing scheme by charging everything to 100%. Something must have gone wrong while I was connecting them.

So, now I am charging the 4 cell battery (Parallel and series). Let see if I have better result this time.
[Eee Pad Transformer General] goodintentions:
Damn it! After tinkering around with the batteries and the battery calibration, I now have the opposite problem. The dock battery is staying at 100 forever, which means my battery indicator can't read beyond the level of the original battery.
[Eee Pad Transformer General] MrNago:
Is there some kind of circuitry connected to the batteries?

If so, maybe that is what's telling the TF there's this much battery that can be used, which should be around half of what you physically have.

Maybe someone with more knowledge about battery charging methods can help!
[Eee Pad Transformer General] goodintentions:
I'm this close to taking out the 2 extra cells and going back to my original setup. All my external tests reveal I've got twice the capacity. But the TF just won't recognize that.
[Eee Pad Transformer General] MrNago:
I would keep at it for a while. Forget about it for a few hours/a day.

A fresh mind can make miracles!

There's definitely something preventing the TF from recognizing the dual capacity battery. You just have to find what it is!
[Eee Pad Transformer General] asdfuogh:
Maybe you should connect them, then let the battery drain to 0 while it's connected, instead of doing it before you attach it inside?
[Eee Pad Transformer General] CobraBytez:
Very impressive! Don't say the keyboard is slightly curved, say it's more ergonomic :P.
[Eee Pad Transformer General] goodintentions:
Just so everyone know. I am officially giving up on the battery mod. Here are the reasons.

So, my first problem was balancing the cells. That was simple enough. Just balance them before hooking them up in series. But then the TF wouldn't recognize the new capacity even though my external tests showed the capacity have been doubled.

So, after painfully playing with the battery file, i think I finally got it to look at the new capacity.

Then another problem came up. The parallel cells came out of balance. This was actually quite surprising to me. After all, parallel batteries are suppose to be self-balancing. After much research, it turned out that lipo batteries suck at self balancing. After about 2 or 3 cycles, they have a 90% chance of going out of balance. What's worse, the cells in series also went out of balance.

Let's step back for a moment. Out of balance parallel cells and out of balance series cells. This was turning into a nightmare scenario.

So, I thought I'd try them one more time. I unhooked them all and balanced them again. And again, after 2 cycles they became out of balance.

I simply do not have the equipment to do this. After much research, I figured out that for lipo bats, I needed balancing circuits. Getting them, putting them in, etc. was more of a pain than I'm willing to take.

My conclusion? Take out the 2 extra cells, balance the remaining two, and put them back in series. Then put them back in and just suck it up with 16hr bat life.

My second conclusion? If you want more bat life, just get a higher capacity battery. In fact, I think that's what I will do in the next couple weeks. In the mean time, it's too much of a pain to add in extra cells.

PS - yes, you can now call me an idiot. This whole project has been a waste of time. The only good thing that came out of this is I learned lipo cells don't behave when in parallel like traditional cells.
[Eee Pad Transformer General] mikewire:
Cool mod, too bad the battery didn't work out. Ever thought about adding a single SSD instead of a standard drive?

SSD it's been all the time... i did followed this thread since i heard about this hardmod...

don't they read the threads before posting?

for the thread starter... thumbs up for u, you have patience, which i don't really have.. :D

anyway... im sorry to said...you put a lot effort for this mod... but, it didn't work out...

i did hope this mod really work out....
[Eee Pad Transformer General] goodintentions:
The biggest stumbling block for me was the fact that lipo bats don't self-balance as well as the old batteries. And I simply don't have the equipments to very accurately balance them. And the circuit board that came with the original battery pack is only set for the original capacity.

When I have enough money saved up again, I will get bigger battery packs. But for now, everything is back to normal. I've a 750gb hard drive + 16hr bat life. Good enough for now, I guess.

Added by edit.

Regarding the ssd thing, I kid you not, someone actually pm'ed me asking if I could put in a 64GB ssd for him. After scratching my head, I asked him why not just go out and buy a 64GB sdcard? Never got a response from him.

I think the problem here is people who ask about why not just use an ssd instead of hdd think the ssd is such a new thing that neither myself nor anyone else before them knew ssd existed. So, they just assume we're a bunch of dumbasses here at xda who don't realize ssd is better than hdd. Either that or they are filthy rich and a couple thousand dollars equate to their daily allowance.

I actually get emails from people honestly asking me why I didn't use ssd. Most of them are sincere. They honestly have no clue ssd costs an arm and a leg. A couple are turds about it.
[Eee Pad Transformer General] h4uw1n3:
I read about it also... since a friend of mine doing repacking battery for laptop... i did asked him about that for my laptop... it's not that easy to handle it...

And ssd... it's funny to read the thread but also pissed off actually.... it costs more than the transformer itself... even the regular hdd with 1.8" costs double... and about the 64gb ssd instead of sdcard... i read about it on the other thread... it's funny, but what u said is totally true... i guess, he already got the sdcard himself... :D

Right now i just waiting for the prime on the market, and i will got myself tf101... if it's possible, i want to get this hdd hardmod also...

Anyway... did u able to turn the form back? On the image, u are not be able to close your pad properly...
