[Battery] Extended Battery or just Battery with more "juice"

I'm looking for an extended battery for the sgy of my Girlfriend. I have also the choice to solder two stock batteries together (parallel). But than I'll have a problem with the battery cover. Is there anyone with experiences in extended battery (not external) from sgy? Or is there anybody with experiences in soldering li-ion batteries together?
Thnx

external batt pack need to be chosen carefully, some dont work with SGY (like mine)

Does your battery heats up? because mine does.....

What do you mean? I've not jet built my own double sized extended battery, but I want to.
There are no extended 3000mAh batteries for SGY. So I have to buy two 1500mAh. These I'll solder together parallel, so I'll get a 3000mAh battery and build a custom battery cover

I think you should be carefull since the circuit only tolerate up to 2000mA current.

Why? The discharge load is the same, but the battery can support longer the discharge load (mA) at 3,6-3,7 Volts. So I dont put more mA in the circuit, just able to do it longer.

you sure ccoz i think theyd give a higher voltage rating if put together,,,

They give more voltage if you put them in series, but if you put the in parallel they give more amperes

Connecting two batteries in parallel should do the trick but it would take time to recharge the battery. How were you able to create a custom back cover? can you show it to us?

on ebay you find a 10 EURO 1500 mAh batt pack , and a 2800 mAh pack for 15 EURO.
sticks into usb socket.

portable mobile charger 1500 mAh
I got meself one of 'em at 10 EUROs.
it has got a Samsung + mini USB socket to charge it. if stuck into SGY, the bottom face is flush with SGY bottom cover.
at 15 EUROs one gets same thing with 2700 mAh of juice. These things are less hassle than changing batteries.

Yea but the Device just takes what it needs. So two batteries (1100mA) results (2200mA). The phone takes what it needs (1000mA in a hour may be) so it takes 2,2 hours instead of 1,1 hour until the juice is out

[Q] Does ICS have correct percentages for extended batteries?

Okay so, my last phone was a Droid X2 and I got a 3500 mah extended battery for it. It was on Android 2.3.5 and Android's battery meter did not correctly read the battery's percentage.
When it got to 1% battery it would simply stay there for a while before it died.
I am wondering if this problem is fixed with the Galaxy Nexus or ICS in general?
I purchased a Seidio 3800mah battery and I'm curious to know if I can rely on it's battery readings.
Thanks in advanced!

I have the official Samsung Extended Battery (2100mAh) and it reads it perfectly. Charges all the way to 100% and then dies at 0% (doesn't hang at 1%).

Thanks for the quick response
I see you said you have the official battery and I'm wondering if there's anybody with a non official battery (if that even makes a difference).
Also I'm wondering about high mah batteries such as the 3800 mah from Seidio or another from Mugen Power.
Thanks

The percentage comes from the chip in the battery, not ICS. So any official battery would output the correct SoC which the driver can read. A cheap battery may or may not depending if that manufacturer setup the chip correctly.
Android 2.3.5 was identical. If it was a 3500 seido they typically give correct charge. If it was a cheaper one then thats why your droidx didnt display properly.
Has to do with the fuel gauge chip, not the OS. Galaxy nexus uses max10740. Nexus one used ds2784. Droidx was totally different too. All depends on that chip.

Yes it was a cheap off-brand battery and that probably explains why it wasn't showing correct percentages.
Thank you!

[Q] Best battery besides the stock one.

I want to buy another battery with higher maH for my Desire HD. So far I've been able to find 1500, 1600 and 1800 maH batteries. But do these really work better than stock battery? If there is one, please let me know the brand to go for. Thanks.
I am sorry for having this posted here. I should have done that in accessories. Sorry.

I have the 1600mah on DHD and its the same...
Like original 12xx..
Maiby one hour more..
Sorry for my english :S

The batteries that are legit are the 1230mAh stock HTC replacement battery, 1230mAh OEM battery, 1300 Anker battery, 1500 MUGEN Power battery and some other trusted brand. Other than that are either fake or low quality built. You can also use the 1800mAh Sensation/Evo3D battery mod in the Accessories thread.

Mugen
Desire S • Fallout V2.0.0 • xda premium

some batteries can make power worse and system has his own capabilites and forcing it to use more power than it can iy will damage the power of ur device

ANKER 1600mah works great and much longer

is it a 2500 or 1500 battery???

Hi all,
I recently purchased a new battery for my arc. It says it is a 2500 mAh rather than the standard 1500 mAh that comes with the phone. I put it into to my phone charged it like it said and i didnt realy get much more from it. I downloaded an app that gives you the battery info and it said it is only a 1500mAh!! I contacted the company and they apologised and sent another one out and this is doing the same. Before i complain to them i was after some advice
Do i need to do something with my phone like calibrate the battery or something or is it that the company are telling lies by saying its a 2500mAh battery but in fact its only a 1500mAh?
Any help would be great as i dont want to complain if iv not done something right haha
Thanks in advance for any help
Hels x

The arc is hard coded to only read 1500. So your arc will drop to 0% but if you remove the battery and put it back in, it should read the remaining charge if your battery really is 2500
Here's what was posted in another thread.
3. Here comes the tricky part:
The phone seems to be unable to display accurate readings of the battery.
It drains from 100% to 1% approximately the same way stock does and then I have to pull it an re-insert it and when the phone boots it displays 65%. Same way, every time it hits 1%, I have to do the same and the percentage rises.
I looked into /sys/class/power_supply and found a folder called semc_battery_data. I searched further and realised that the capacity (1500) and type (Li-Pol) are actually hardcoded on kernel level. HTC developers have already addressed similar issues on kernel level.
I talked to Bazoocase (the developer of the 0% battery issue work-around, so pretty much the expert on the Arc battery gauge!)
about it and he confirmed that this is really the case:

If the battery have the same size as the original, then it isn't a 2500 mAh battery. If it is a 2500 mAh, then it must be bigger, so you need a other back cover. If you buy a gold battery, or something called like that, they are faked. Most of that batteries don't have a over charge protection, so they can heating up, damage your phone, or blowing them self up, if it is a real cheap battery.

i've a 11000maH. It's amazing

What's it like having a brick?

Ask someone with an arc to compile a special kernel for arc for 2500mAh battery capacity.
Tell them it's located here.

No no, don't do that. You must be absolutely sure it's a 2500 mAh battery, otherwise you damage your battery, or phone. A 2500 mAh battery cannot have the same size as a original 1500 mAh. If you want a 2500 mAh or higher, then it is a extended battery, with a other back cover. Use a multimeter to test it. You will see that the batteries have 1500 mAh, not the promise 2500 mAh.

Thanx to this post i was about to buy that kind of battery

I also have an extended battery, but not 2500 mAh but around 1850 or so. 2500 in the same sized housing seems to be pretty unrealistic.
I'm interested in a fixed kernel with higher battery capacity built in. But, yes it does involve some risk. For instance, you can not use your original battery anymore...
Any news on this idea of an modified kernel?

Just make sure it is a real 1800mah, or the chip will charge it longer than its true capacity, heating it up and causing fire/explosion.

Thanks MarioLouis. You're right.
In another post about the same topic from iridaki, there mentioned that with this kernel mod you can use both the high ànd lower capacity battery's.
Unfortunately I'm not on gingerbread so can't test the proposed mod from Irdaki's post.

battery M9 with different capacity

Does anyone tried a different battery capacity? I found a 3000 mAh on ebay, did anyone tried it?
Do you think is harmful?
Thank you in advance

Is this battery built by HTC was is a third-party battery that is working with HTC?

It isn't a HTC battery, is a spare with more capacity, but I don't know if it's harmful or not, I didn't found anything in internet about it...

I don't think the battery capacity will harm the phone, maybe just the battery will hold longer or not, depends on it's quality.

The point is: does the actual stock battery has a fix number of cycles or whatever? The actual battery has 2850 mah capacity, the new one 3000...the difference of 150 mah will be recognized by the mobile? This is my concern..

The phone will charge and discharge the extra 150mAh but the correct capacity will not be reported by software.
Anyway 2850 vs 3000 is a little change, and if the battery quality is lower than HTC original battery maybe you'll not see any difference or maybe the battery will hold shorter.

From what i've seen on the Galaxy Gear S forums, somebody fitted a bigger battery inside and it worked just fine.
And his watch now lasts a few more days.
Anyway, for 150mAh more is simply not worth the risk.
