Well 2400mAh instead of 3000mAh. Maybe it is fake. Mugen is very expensive battery manufacturer so customer can expect They have high-end batteries for prices They request.

What concerns next advices :). Hmm, Your English is much better than my so I have some troubles to understand Your idea without any pictures. Is it similar to what I depicted on attached .jpeg file ?. If Yes, I guess mentioned battery retainer will be under drawn original tg01 battery ?

I could not upload .jpg file ( do not why ) so I zipped it.

The chart at www.batteryboss.org also shows examples of Mugen batteries that tests show are way below their rated capacities.

Yes sir, that is exactly what I plan to do. I just need a method to attach those small contact springs to the battery terminals of the upper battery. Yes, I can try to solder them, but I am afraid of causing more damage to the battery. Right now the two new Cameron Sino batteries wired together are working better than I had expected, but I would at least like to get around 3000 mAh capacity until I find a 'naked' li-po battery like you have successfully used. Just think of me as your student, fxdjacentyfxd. ;)

Cheers, my teacher! :D
[TG01 ROM Development] fxdjacentyfxd:
He he student. I had some students several years ago :)

Well, I have big experience in manual soldering so from my point of view, golden pads from Cameron Sino battery shout to me "Yes ! Solder strings, solder strings".

Really, no kidding. They are so big that it is natural to solder the strings provided the strings are made from something one can solder easy.

1) Cover golden pads with tin. Simply use soldering tool with enough big power ( not larger than 100W however) but relatively thin arrow. I use so called transformer soldering machine to connect elements that are relatively big or have big heat capactity. Small iron machines with docking stations are useless.

Have You good tin ? I mean with resin inside ?

2) Do the same with the end of string

3) touch soldered pad with soldered spring and touch it for a while with soldered machine as long as tin from both parts connect together.

I do not know whether my explanation will help You a little bit but I can not see any other method. Any good conducting adhesive ? I am afraid it does not exist but who knows

Regards

[TG01 ROM Development] CrashMurdock:
Yes, your explanation is very clear and I do understand...thanks! :D I will try it tomorrow morning. My soldering tool is shaped like a pistol and it has a spring-loaded switch to select either 30w or 130w. Default is 30w. I have to use the 130w setting because 30w is not hot enough. I am using a tin solder with resin. I also have lead-free solder but it requires a high temperature to melt so I didn't use it to solder the batteries. Soon I will post pictures with descriptions. Thanks again for your help, fxdjacentyfxd! ;)
[TG01 ROM Development] fxdjacentyfxd:
Yes, it is my "transformer" soldering machine :))). Pistol, but my has 100W. Very good in cases like our case.

OK, here they are attached as thumbnails since I can't simply Insert Image directly from my computer. I have also just complained about this in the Q & A forum.:mad: EDIT: Got around this limitation by attaching the images then using the new xda URLs to Insert Image .

Photo 1 shows the two batteries taped together after I cut the grooves and inserted the short copper wires. I had to highlight the copper wires as they didn't show up well.

Photo 2 shows the process I went through with annotations

Photo 3 shows the embarrassing solder job I did...but it works.

Photo 4 shows the new battery pack installed in the phone. I have to say battery life has more than doubled and probably is closer to triple of what I had with the original used Toshiba standard battery.

Let me say that this is obviously not fancy or pretty and is my first attempt at this sort of thing. It is meant to be a temporary solution until I purchase a ~2200 mAh 'naked' Li-Po battery that will fit under my Mugen cover wired together with the original Toshiba 1000 mAh or one of these '1100' mAh Cameron Sino batteries.

I will say this mod has really improved the phone along with your excellent ROM, fxdjacentyfxd, so thanks so much for all your help! :D:D:D:D The next trick is to add the original Toshiba battery via spring contacts, or a new Cameron Sino since the Toshiba may be tired already.
[TG01 ROM Development] fxdjacentyfxd:
Well done :)

I am under impression You "invented" such sandwitch connection prepared for springs connections with original tg01 battery.

From the begining I have always thought about li-pol batteries , maybe because I have largest Mugen cover but Your solution seems to be perfect ( optimal ) for thouse having only original ( spare ) batteries.

Take into account You can theoretically use not original tg01 battery but any other ( larger capacity ) battery with comaptible pads ( electric compatibility and springs problem but one can solder such bigger battery to

Cameron Sino sandwitch via two short wires ). You have almost 8mm room where You are going to place tg01 battery.

Wait for final result :)

[TG01 ROM Development] CrashMurdock:
Before I received the Mugen cover I wanted to use two of my Sony camera NP-BG1 ~1300 mAh spare Li-Ion batteries with the original Toshiba. That would provide 3600 mAh total. The terminals are positioned almost the same, although in reverse polarity, but the big problem is they are 8.5mm thick and the Mugen cover will barely close with one, but will not close with two because the Mugen cover is curved in shape. After learning of you using Li-Po as 2nd and later 3rd batteries successfully I want to do the same because Li-Po batteries are more powerful (higher energy density) and also lighter in weight from what I have read.

I have some other things to do today so hopefully tomorrow I can add the springs to have three batteries.

Cheers! ;)
[TG01 ROM Development] CrashMurdock:
Finally added the third battery (original old Toshiba) a few days ago. I was not able to solder the springs onto the terminals like I had planned (lack of soldering skill) so just cut two ~45mm lengths of copper wire, stripped the insulation back about 30mm and rolled the bare wire into a sort of ball to place between the recessed like terminals of the facing batteries. I then taped the insulated sections in place then taped the two batteries together securely to make sure there is good contact between them. Maybe because the Toshiba battery is old I'm not really noticing a difference. I've looked for a 1500 mAh battery to replace it but haven't found one similar enough size and configuration yet. I may just order another Cameron Sino '1100' mAh replacement battery.

I'm amazed at how power hungry these phones are. The day before adding the third battery I happened to have a couple of long phone conversations. After turning on the phone in the morning the battery meter still indicated 100% from the previous day's minimal usage. I received a call that lasted about an hour and later that day another that lasted about 30 minutes. I was shocked that the battery meter had dropped down to 60%. Knowing the battery meter is not accurate I rebooted the phone and it then indicated 70%, still low considering it was just phone calls with Wi-Fi, Bluetooth, etc. turned off. This is much better than with just the original old Toshiba battery which only lasts about half a day if I make a lot of phone calls, but still not good. I see now why you keep adding more battery capacity. Had I known battery life would be this bad I probably would not have bought this phone or at least bought the deeper Mugen back cover and crammed around 5000 mAh battery array into it. Does my battery usage seem typical to you?

Cheers!
[TG01 ROM Development] fxdjacentyfxd:
Hi.

Nice to here You finished Your work :)

I am not good recipient of Your last question because my talks are not so long as Your :). My battery improvement is concerned general with long outdoor usage of tg01 ( talks, gps, internet ) not only with long talks.

First, it is strange You did not notice any difference adding original tg01 battery. It is theoretically 30% more.

From my experience, any gsm operations ( calls, gprs ) are very gluttonous but it strongly depends on distance ( connection quality ) between the phone and base station ( current can reach even 0.5A ). There is the thread on forum where I described measured current during different phone operations. So it is possible that having bad quality connection and strong backlight one can observe battery voltage drops as You noticed. Having backlight off is not bad idea with my rom :) even if it allows to do something other during call. Any screen taps are very gluttonous.

On the other hand maybe it is worthy to ask people who were changing radio versions a lot, what radio is the best in the matter ?

Did You observe that changes in power management have any influence as far as battery life is concerned ( even during calls ) ?

Regards

[TG01 ROM Development] CrashMurdock:
I agree it should theoretically give me a 30% increase but I think this old Toshiba battery is weak. I noticed much longer battery life when I first changed from the Toshiba battery to the new Cameron Sino single battery. Then after I soldered the two CS batteries together it seemed like the battery life more than doubled. Maybe the 3rd battery is not making good electrical contact because the connection is not soldered, just taped together. It does seem to take much longer to charge to 100% with 3 batteries instead of 2. I haven't run any tests and have only had the 3rd battery installed for a few days now so my perception might be off.

I was close to the cellular tower during those long phone calls so that should reduce required current, correct? I have the backlight set to turn off after 1 minute, but I don't know if it turns off automatically while talking or not. I haven't thought to check that, but I will.

I don't understand what you're asking? I have CPU speed set to max, which I know is gluttonous, but I have phone set to sleep after 1 minute on battery. I often check Task Manager to stop any previous apps/processes from running in the background.

Oh, I forgot to ask you. Every time I turn the phone off I get a message, "Some application wants to execute. <<PowerOffHint.exe>>..." What is that and can I disable it?

As always, thanks again fxdjacentyfxd!!! With your help this phone will be the best! :D:D:D
[TG01 ROM Development] fxdjacentyfxd:
Hmm, maybe You have only a little bit above 2000mAh not 3000mAh ?

But I forgot to give You a hint and/or ask about charging process of such big battery. From my experience ( not with tg01 only but other devices too. I consulted it with other person familiar with PNA devices ) when one modify battery capacity a lot ( new battery is much biger than original ) and try to charge it via embeded charger then .... such battery will not charge in full way !!! In my tg01 I have such behaviour too. It is typical in PDA/PNA devices ( I do not say in all devices but problem is real ) that internal chargers have some kind of counter?time meter?. It seems to be based either on charging period or maybe charged energy. I do not know but it is. What happen thus ? Simply charging process stops and You think battery has been charged full. It is not true.

What is solution ? Simply disconnect charger for several seconds from the device , connect again and charge untill ..... internal charger will switch charging process off again :).

That is why I did for myself some kind of electronic breaker. Any external charger that I connect to the device ( its high voltage end 230V~) I connect through my breaker. It works in the way that for about 2 hours charger is connected to 230V~ and then is disconnected for about 15 seconds. And again is connected for 2 hours and so on. Charging this way my huge 4750mAh battery in the evening I have guarantee that in the morning battery will be full charged.

He he :). It is my stub on original PowerOfHint.exe - program that is responsible for switching tg01 off. It was created before I did my battery driver so that to prevent any internal process to switch tg01 off ( especially when battery has 0% ). You have to know that original PowerOffHint.exe can be executed in silent mode and some system processes/drivers call it this way when battery is 0%. My stub catches it and give You chance - to switch off or not to switch off.

If You select switch off than my stub calls original PowerOffHint.exe. If not it simply ends doing nothing.

I had a plans to make it configurable ( via registry ) so that this additional dialog did not appeare but .... not worthy :)

I usually just plug the phone into my laptop USB. I have no idea if the batteries are all getting fully charged but I know that it took much longer to charge the pair of CS batteries than the single battery and now it seems to take longer to charge all 3 batteries. I assumed because of this extra time it was fully charging all 3 batteries to 100%. Update: Taking your advice I removed the phone from the USB showing 100% charge and plugged it into the external charger. Interesting that it charged for about 15 minutes before the charging light went out. I unplugged it for 15 secs and then it charged again for about 8 minutes before the charging light went out. I've just started charging it again. Hmmm...maybe adding the 3rd battery was keeping all 3 batteries from automatically charging?!

No problem, I'll leave it alone.

Thanks again for sharing your expertise, teacher! ;)

Cheers! :D:D:D
[TG01 ROM Development] CrashMurdock:
Great news and once again thanks for the tip, fxdjacentyfxd!;) I finished running the battery pack through a few charging cycles trying to use the 15 sec unplugged interval like you recommended last night using the external charger. I had to do it manually as I have no timer. This morning I ran it through 1 charging cycle for a fresh start to check if there would be a difference throughout the day. Made several 5-10 minute calls today and this evening there is still 90% battery power remaining. This is the best result yet! A reboot still indicated 90%. This is more in line with what I had originally hoped for (weekly charging) so I am very happy now.:D Will probably still purchase another CS '1100' mAh to replace the old Toshiba, which seems to be a little weak. That way I can hopefully modify the old Toshiba battery like you did to get it ready for a Li-Po big brother.:eek:;)

I have to admit that I wondered how the charging circuit knows when the other batteries are fully charged and the answer is it doesn't. I thought that during charging, when the first battery became almost fully charged its internal resistance would increase rapidly causing the battery with lower resistance, because of a greater discharge state, to automatically receive the current until full, then automatically charge the 3rd battery for the same reason. Incorrect thinking? Since these batteries are wired in parallel aren't they always trying to reach an equal voltage state (equilibrium)? I noticed that last night if I missed seeing the charge light go out and there was an interval of 10-15 minutes of not charging that when I unplugged the charger and plugged it back in the charging interval went up to about 15-20 minutes. Is this because the batteries have reached an equal voltage state?

Still unable to log in to Skype after installing it on the device instead of the microSD memory card like someone suggested. Also, still hope to get some version of iGO GPS nav software working.

Oh, almost forgot. During normal charging and even last night after several charging cycles the batteries don't seem to get warm. I didn't remove the back cover but it felt like it remained at room temperature. Is this normal?

Cheers!:D:D:D
[TG01 ROM Development] fxdjacentyfxd:
Good news :)

During charging process battery resistance decreases not increases. Problem we have is I do not know whether in such case as You have ( batteries are connected parallel but not directly but through their safety circuits ) something unpredictable can happen. Weak battery will have larger internal resistance but it is not a problem becuase charging current will flow mainly to good batteries. Sooner or later they will charge fully ( it would be difficult when batteries were connected serialy ). It will be true in case when we have "naked" batteries connected together not like in Your case but maybe designed safety circuits do not disturb charging process . Hard to say. To be sure it is better to have all batteries the same quality.

What You observe ( after short period charger disconnection and connection ) can be concerned with two facts. As You surely know, stoping charging cause that voltage drops ( internal processes ) to some point of balance. It will drop even if You diconnected charger for only several seconds.

Secondly, internal tg01 electronic charger has some histeresis ( ambiguity ) ( it is my observation and speculation :) ) and it additionaly causes that when You connect charger again You have to wait few minutes to stop charging process.

Do not bother it at all, really. Problem with too warm batteries can appeare only in charging circuits which utilize charge current limits for given battery.

For example naked li-pol 1000mAh has about 1A max charging current.

2600mAh has about 2.6A max charging current.

Only then problem with temperature can happen. So You see it is not problem in our toy and in most of other toys.

In tg01 max charging current is less than 0.5A and in case of my or Your sandwitch situation is much better because this 0.5A must be divided into all batteries. Thus do not remove back cover. It has not any sense.

[TG01 ROM Development] CrashMurdock:
Yes, I also have no idea what is happening during charging because there are 3 charging circuits trying to control the charging process at the same time.

I only unplug the charger after charge light has automatically turned itself off.

Yes, that makes perfect sense. I will not worry about low temperature in the future.

It is now 6:20 P.M. My battery meter was indicating 60% power remaining. After rebooting it is indicating 80%.:D:D:D Today I had calls about the same as yesterday so 80% = 10% per day since I did not charge the battery again so I am very happy!:D:D:D I wonder if allowing the phone to go into sleep mode after 1 minute may be a problem with the battery meter reporting correct power. Is that possible?

I just ordered another CS '1100' mAh battery for £4.99 including free shipping. With 3 new batteries maybe I can go a full week between charges!

Thanks again, fxdjacenty, for taking so much time to help me. I hope I am not boring you too much.

Cheers, my friend! ;)
[TG01 ROM Development] fxdjacentyfxd:
No, electricity ( electronics ) is my passion so I am not bored :)

I am glad You are pleased with Your big battery.

I do not think Your suggestion will fix battery meter. All is ok as far as peaks current are not present but when such will appear and in the same time electronic circuit will measure battery voltage , we have what we have - incorrect battery level. I still do not know whether it is software or hardware problem because after such peak current, voltage will increase but it is not reported in the system.

Let me know when You add next battery :)

Regards

fxdjacenty
[TG01 ROM Development] CrashMurdock:
I wasn't trying to 'fix' the battery meter as I know it isn't accurate. For some reason rebooting resets it and it gives a higher value for a while, usually 10%. I've read that in the forums here also. Now I doubt that rebooted value is accurate. In fact, shortly after posting my last comment my battery dropped to 70% even with no use as the phone had been in sleep mode. After trying to get it to connect to my new N-spec Wi-Fi router for about 10 minutes the power dropped to 60%. I rebooted it and it then indicated 70%. I turned it off for the night and didn't recharge it. It indicated 60% yesterday morning. Also yesterday, made only 2 or 3 short calls, but by late afternoon the power level had fallen to 26% where it remained until I turned it off for the night and put it on the external charger.

I'm suspecting the weaker Toshiba battery may be dragging down the other 2 batteries because it had a tendency to drop off faster than the Cameron Sino battery in single battery mode. When my new CS battery comes in I'll have a better idea. One thing is certain and that is I'm nowhere near weekly charging cycles even not using the phone much and turning it off each night.

Before I forget, any tips on connecting to Wi-Fi networks? My phone finds my network and tries to connect but just won't. At first I had the router/modem set to WEP security settings then changed to WPA because with WEP the TG01, my Windows 7 laptop, and even my buddy's W7 laptop wouldn't connect. Now the laptops connect, but the phone still won't. Don't know if this is a port issue, like some people are saying is the reason I can't connect to the Skype server, or another setting like TKIP and/or AES encryption.

As always, thanks for the help, fxdjacentyfxd! I appreciate you!:D:D:D
[TG01 ROM Development] yaro666:
I've had same problem when my brother changed modem settings - he set IP and ports to static. After modem reset to factory settings, it works great again.

Tried with opened wifi, WEP, WPA, WPA2 and many ROMs.

Maybe your settings changed, but Toshiba keeps old settings in memory? Try to find and edit your SSID in settings --> connections --> wifi or just delete it and try to find network again.

You could try somewhere else to make sure, for example McDonald's have hotspot.
[TG01 ROM Development] CrashMurdock:
Thanks for the tip yaro666!:D I played with the phone's Wi-Fi connection settings a bit more and finally ended up deleting all my SSID network settings then reentered WPA with AES, again. After I entered the security code it suddenly connected. Still have Skype problem to solve and nav software, so almost there, finally.

Cheers! :D:D:D
[TG01 ROM Development] CrashMurdock:
Sorry guys, finally added some Thanks!

fxdjacentyfxd, yaro666, & Pere,

Sorry for not clicking on the Thanks button sooner as I've been so involved in getting my TG01 dialed in I didn't even notice the Thanks button. You guys have been a great help, especially you, fxdjacentyfxd, for your many many tips, suggestions, diagrams, and humour. Just wanted to say that I appreciate you guys!!!!! My battle ain't over yet so hope I can still bug you fellas with a few more questions in the not too distant future.:eek:

I just found some 'wire glue' on eBay while looking for something else. The description says:

Electrically "Conductive" Wire Glue with Advanced Micro carbon Technology

Simply apply it as any other glue and let it dry that's it very easy all without any soldering

Make Electrical Connections WITHOUT Soldering or Heating

Conductive like Solder

Here are a couple of listings:

http://www.ebay.com/itm/Conductive-Wire-Glue-PDA-MOBILE-MP3-PALM-/370538638400?pt=LH_DefaultDomain_0&hash=item5645d2ec40

What do you think? BTW, still waiting for my CS battery to arrive. I've worked out a simple 'system' for charging my battery pack. I let it charge completely. Whenever I notice the charging light is off I unplug the charger (time varies) then I recharge it again and repeat the process until the charging cycle is just a few minutes. It's not scientific but it does work. Lately I've been using the phone a lot and get about 3 days between charges.

Cheers!;)
