REAL 2600mAh battery mod - Motorola Photon Q 4G LTE

Hello all,
As many of you, I am reluctant to give up with our loved last Qwerty survivor. Therefore, this was the moment to boost its battery life.
The selected new battery is BL-54SG from LG G2 (thanks to @no3id)
The process is very simple: disassemble the stock battery to take out the battery controller PCB and solder it to the bare LG battery.

Charging to 100% OK.
Perfect length and height, only a bit thicker (you can see the bulging cover in the last picture)
Still testing!! Do it at your own risk!!

Thanks for sharing reinoso!
It looks like you cut the upper tabs that hold the stock battery down, is that true?
Does your battery level indicator still work with this retrofitted battery?
Did you consider somehow sanding the back case to try to avoid some of that bulging?
Let us know how it goes once you field test it a bit!

Nice one.

It runs perfect, battery life improved at least 40%.

Man, you've done a great job!
One more question, for your conversion you've used some random "genuine replacement" battery from ebay for $15? I mean, any 2610MAH BL-54SG will do?

As it's not easy to buy a genuine LG BL-54SG here, I've decided to give LG BL-59JH a try.
It's 2460mAh, which still seems like a good upgrade and I could easily pick it up in a store on my way from work to home yesterday.
It's not so wide as BL-54SG, so it can be installed without any modification to the battery support frame.
My back cover seems to hold rather fine even with NFC antenna back in place, but there's indeed a bulge.
What's important for me is that the phone still fits to Motorola's original car holder without issues.

will there be any way to do this without any soldering?

Hi
Thanks for your sharing! My Photon Q battery has been bad for already half a year. It bulged a little bit and the battery service life was getting less every day.
So I bought a BL-54SG as well 12€, so about 13 USD here in Germany. Hope, it's a genuine one. Disassembled both batteries, soldered the PQ-battery-controller to the bare LG battery and done Was slightly difficult because the positive pole of the LG battery was eating the heat of my soldering station... But now it's working
Closing the battery door was really hard. At first it didn't clamp but now it looks like it stays closed.
I have the same "marks" on the backside, but before my phone's backside was'nt flat because of the bulging old battery, now it's because of extended capacity. Something I can live with!
So thank you for your advice! I'll now test this "mod" as well
//EDIT: NFC seems to be broken now, though...
//EDIT2: OK, working again peeled this black stuf from the old battery and put it behind the NFC antenna on the new one

As the glue holding the previously flat (now bulged) top part of the back cover started to loosen up, I've decided to try an alternative to better accommodate the thicker battery.
This my first try on an 'old gloves leather back' hack.
The soft leather is held by the thin 3M double sided adhesive tape for touchscreen/lcd repairs.
To my surprise, it's still holding fine after a few days of use.

I will pay anyone if they want to modify and send me a battery. I don't know how to solder

Well that sucked. I had a bad battery, bought a new one. Saw this thread, decided I'll get an LG and try the mod with the old battery.
New battery arrived, aaaaand snapped the PCB from the old one trying to get it off :/
What would happen if I wired the battery up just through the +/- pins? Without the two middle ones?
What are the middle pins for?
EDIT::
Goddamnit, Droid4 post linked to here and without looking properly they looked the same.

I'm thinking of upgrading my Droid 4 battery. However I don't want to give up wireless charging. I have already troubles to fit Qi receiver in. So I need new back cover (can't find any) or thin battery and as much mAh as possible. Here are couple alternatives:
Comparison original battery for Droid 4/Photon Q 4G:
EB-41: 2.75 x 1.89 x 0.151'' 1785 mAh (69.85 x 48.00 x 3,835 mm)
Alternatives:
BL-54SG: 2.68 x 1.90 x 0.217 2610mAH (LG, 68.05 x 48.25 x 5.50mm)
BL-54SH: 2.67 x 1.90 x 0.221 2540mAh (LG, 67.90 x 48.30 x 5.60 mm)
BL-59JH: 2.56 x 1.73 x 0.23 2460mAh (LG, 65.02 x 43.94 x 5.84 mm)
EB-L1G6LLUCSTD: 2.48 x 1.99 x 0.213 2100mAh (Galaxy S3, 63 x 50.5 x 5.4 mm)
EB-B500BEBECWW: 2.72 x 2.01 x 0.170 1900mAh (Galaxy S4 mini, 69.10 x 51.00 x 4.32 mm)
TLi019B2: 1900mAh (Alcatel One touch, 62.18 x 55.81 x 4.85 mm)
* RED color means "maybe" too big size
EDIT: New founds:
EB615268VU: 2.66 x 2.04 x 0.240 2500mAh (Galaxy Note, 67.50 x 51.90 x 6.10)
BV-5QW: 2.64 x 2.02 x 0.215 2420mAh (Nokia, 66.96 x 51.28 x 5.46 mm)
EB-L1M1NL: 2.60 x 1.97 x 0.197 2300mAh (ATIV S, 66 x 50 x 5mm)
EB535163LU: 2.6 x 1.9 x 0.2 2100mAh (I9080, 66.04 x 48.26 x 5.08 mm)
B0PA2100: 2.50 x 2.00 x 0,203 2100mAh (Desire 310, 63.54 x 50.55 x 5.15mm)
EB-BG357BBE: 2.72 x 2.00 x 0.165 1900mAh (G357, 69.05 x 50.9 x 4.2mm)
Too bad that I can't find any 2.7 x 1.9 x 0.16 batteries with 2000-2200mAh. I think that should be possible. Only 100mAh upgrade to 1900mAh is maybe too little.

1500 mAh battery DealExtreme $8.70

About a month ago I was browsing DealExtreme for some stuff and I ran into this for only $8.70: 3.7V 1500mAh Battery with Battery Charger + EU Plug Power Adapter Set for HTC desire Z
I ordered the 1500 mAh battery and nearly three weeks later it arrived in a yellow envelope. It works great and it comes with a wall charger for the extra battery (WITH some colourful LEDs (pink for charging and blue just for fun)). As I was just about to write this notification I browsed DX again and also found this one:
Replacement 3.7V 1500mAh Cellphone Battery with Charger for HTC Desire Z/Vision/BB96100. You might notice the lack of European power plug support, but it also is $0.70 less
You might also notice the USB port. I just tested it and it seems to be working (the red notification LED is on, but the battery icon doesn't change, might be due to the fact that the battery is already full).
I tested it and it works, so now it's up to you guys to order one if you are in need of an extra (cheap) battery!
Edit: On the wall charger is the following written on a label: For T7373 Touch Pro2 (HTC Touch Pro2/T7373/T7388/T8388)
So the battery of the HTC Vision might be the same as the Touch Pro 2?
Anyway, just thought I should share.

There are a number of other HTC batteries that would work (or could work). Good find.
Note: I've had the same charger for my HD2 batteries. Be extremely careful when you whip out the prongs. I had a set snap on me, rendering the charger useless.

The prongs on my wall charger do feel sturdy, but I can assume not all the Chinese stuff has the same quality.

I noticed the Temperature display that SetCPU has built in doesn't seem to show the proper temperature with the DX batteries. Caps out at 25 and it is definitely hotter than that.

I got a freebie 1600mAh battery from an EVO4G and I peeled the tape off so it would fit. I noticed on the metal cover it said 1200mAh.

I didn't notice it, but SetCPU says the temp is 25.4 degrees. The battery doesn't get warm, it felt quite cold (dunno, about 20 degrees or so).

I hava a touch pro with a 1800mAh and the original 1500mAh battery, so after reading the post I pulled it out of the drawer. Unfortunately it doesn't fit without modifications. The size and location of the pins is the same, but there are 2 plastic slots on either side at the base of the battery that prevents it from being used.

Would it work the other way round then? Aka putting the Desire Z battery in the Touch Pro 2?
The other way around it doesn't fit either. Just tried and made come pictures to show you why.

Thanks for uploading the pictures. There is only a teeny tiny piece of plastic in the way... I understand that you don't want to cut if off though. Too bad it doesn't fit.
to those that have purchased this battery, how many hours are total are you getting this with moderate use?
Thought you guys might be interested...DX now has a 3000mAh battery with plastic back cover for $13.90.

Saw this on engadget too and was seriously contemplating getting it. Tho I wonder how much bigger this will make the DHD feel
I was just going to post on it! You beat me. Seems like a win-win. I'm already using a Mugen 1500, so if I add this (which is 1500) for a combined battery life of 3000, I should never have to worry about battery life again. Here is the direct link if anyone wants to check it out. http://www.power-skin.com/battery-cases/ap1508des/htc-desire-inspire.html
Just saw the post on engadget as well, looks promising, hopefully it doesn't make the phone to thick, but would be a excellent thing for travelling if nothing else!
They just replied to my comment on their facebook page that there will be international shipping soon!

Wished they shipped to Canada. For $60 I'd give it a try!
I have a question look at the specifications Powerskin it is 5V, the problem is this is compatible with our European phone with a 3.7 V battery?

It's universal, USB power is ~5V. All batteries in all DHDs say 3.7v remember that all this extra battery is doing is providing power via USB, therefore it needs to be ~5V.
Correct me if I'm wrong anybody.

Doesn't seem any thicker than with a Case Mate Pop case. I have one so I'm sure I can live with this.
Sent via 1s and 0s through time and space using my Defy.
It needs to be 5V to appear as a charger to the Desire HD. But I see several issues with this:
-The Desire HD will be in constant charge mode until the external battery discharges. Only then the internal battery will start to be used.
It's not good to use a device while charging, this reduces the battery life, so this case will reduce the internal battery life.
-Being 5V means that the case internal 3.7V must be pumped to 5V and then reduces again to 4.2 to charge the battery. Pumps and regulators usually have a 80% efficiency, so 1500 x 0.8 x 0.8 = 960. Expect a battery improvement equivalent to 960 mA, not to 1500mA.
Still it's a great accesory for some situations where you spect to have a great consumption, like hicking with GPS, 3G use while moving, etc. And when the external battery is discharged you can remove the case and have the device full charged with its original size.
You can also turn the case off so it won't charge your phone. Then it doesn't charge the phone constantly and the internal battery life won't reduce that much.
Thanks for that picture It does look a bit thicker, but if nothing else its nice to have with you for weekend trips etc when you know you cant charge.
Does it work like a charger in the way that you can turn it off untill your internal battery is almost depleted, then switch it on and charge up the internal one (if you leave the phone idle?) or does it not really charge the internal one, just keep the phone alive on the extra battery?
Anyone tried this yet or has ordered one already? I'm really interested in this, but since I'm only 16-years, I don't have the money to try something out with a chance of not being worth it .
This too thick for my tastes, i like my dhd thin.

It's a fascinating idea, but - converting inches to cm - that is about 0.8cm more, for a phone that is just about 1cm deep. In fact, the manufacturers do mention 0.8cm as a generic add-on. That's a lot of bulk...
For all-day GPS-intensive stuff I take along a 5000mah power pack that does the job nicely, which you just unplug if you need to make calls etc. Back in the bag, and connect it back up
Though I'm sure this powerskin will meet the needs of some people out there.

[Q] HTC evo 3d battery work in HTC Sensation?

I was just wondering if HTC EVO 3D 1730 mAh battery will work in htc sensation?
The batteries look similar, but I don't think it's possible. I hope I'm wrong. It would be great to have a 1730 mAh battery in Sensation

Judging by the picture, not possible as pins are located on different side, so even if you spin batter 180 degrees, they'll end up on the opposite side. Shame, i was really hoping it'll fit.
EDIT. Actually, if you put battery upside down, ie, htc logo underneath, it's quite possible it WILL fit... But, it depends on how HTC puts their pins in, if they revese it on 3D, that'll be a winner

Yep, that's what I was thinking. But still, it probably won't be possible, which is a shame.
Oh my.... As long as batteries are identical in size and + pins are same distance from the corner it can be done!

IT WORKS!!!
I just tried the Evo 3D battery in my Sensation 4G and oila! All you have to do is reverse it and it works like a dream. The only issue one might run into is that the Evo's Battery is a 3.8v and the Sensation's is 3.7v. Might cause some slight wear on the circuitry over time but I'm hoping a manufacturer will step up an make an extended battery cover that works as an antenna before any real damage can be done. Anyways...
YES, IT WORKS.. HTC FTW:
i second that, it does work

just giving another conformation. a customer where i work was nice enough to let me try his battery and it does in fact work, the only other thing is that the battery specifications and warning side of the label show but who cares. i will be buying evo 3d battery sometime soon and enjoying that 210 mah more battery.
Excellent news, this is probably the best route to take towards getting a higher capacity battery for the sensation without resorting to using an extended battery cover.
Now, why didn't HTC just give the same cap battery to both devices is beyond me. Can cost be that big of a factor?

really? because the Tp2, EVO, Incredible and the G2 can all share the same battery.

Didn't know that the Incredible & G2 also shared it, but the Sprint HTC Hero also shares the same battery.
Don't know if this is legit but the 3d evo battery is now on ebay for 30$

That guy was an idiot from the start
I have an HTC EVO 3D and my brother has the HTC Sensation. I bought the Ebay 6n1 kit where it comes with 2 2000mAh Galilio batteries, screen protectors and some other junk. I gave him one of the batteries to see if it would work in his phone, works like a charm.
It's been about a week and his phone seems fine.
I bought 3 1850 mAh extended batteries and a wall charger that say EVO 3d on from eBay for 25 bucks. It works perfectly fine in my sensation and fits perfect. I got 19 hrs if life out of it with moderate use. I tore one of stickers off of it and it doesn't have any other writing on it. Hopefully it a true 1850. If not it doesn't matter I still got 9 more hrs out of it compared to stock.

Htc one mini dead battery. "hack" battery from mini 2 possible?

Hello everyone, i'm new here, first post'ishh
So i have a HTC one mini where the battery died. Been looking online and they are pretty cheap.
But, i have a HTC one mini 2 that has a broken screen and dead speakers etc... But battery is fine. And when it's free i can afford it :silly:
Both of them seem to have same sized battery (physically) but the one on the Mini 2 has a 2100mAh battery compared to the 1800mAh on the Mini (1)
The connectors aren't the same, i have soldering iron, not scared of breaking both batteries. So i was thinking about swapping the connectors so the mini 2 battery could bet put into the mini 1.
My question is, can the mAh difference cause issues? like not being able to fully charge because there's a chip or software that makes it stop at 1800mAh? Or will it just charge till the battery tells it "i'm done" ?
Hope you can help thanks in advance
I would be interested in this as well . Would you mind taking a side by side picture of the two batteries and try if the one mini 2 battery physically fits in the one mini? Best regards

Hi Chaos
Well i've had a lot of work these past months so i didn't get time to check the forum here before now.
I don't have the phones with me right now but when i took them both out and put them on top of each other, they are the exact same size. (batteries)
I've looked on a website that sells batteries and the dimensions on their site are:
Htc one mini: 79 x 54 x 4 (mm)
Htc one mini 2: 78 x 54 x 3 (mm)
Those are not original batteries though but that probably makes no difference (in size). So the one from the mini 2 is smaller and thus should fit without a problem inside the mini 1.
The leads that come out of the batteries are exactly the same and same size, only thing is the connector itself, it's larger on the mini 2. The contacts in the connector itself are further away from each other compared to the mini 1.
So i'm 99% sure that it can be done. I will just give it a try when i get home this weekend. And i will take pictures and post here
Hope it works
Ok soo i got them both apart annnddd... It's not possible.
So both phone connectors have 6 pins. Different spacing though.
It looks like there are 2 grounds on the htc one mini 1 battery. And they go to each side.
On the htc one mini 2, the ground is just one or maybe 2 pins in the middle.
On mini 1, pin 1 and 3 seem to be ground.
On mini 2, pin 2 and 5 seem to be ground.
1 23
456
Hope it makes sense 123456 above is pin arrangement
I don't have anything to test what is + and - But that doesn't matter anyways because the ribbon cable itself doesn't have the negative in the same place on both batteries, so it would be some pretty crazy soldering work to get it work and get it to fit afterwards.
So i'm just going to order 2 new batteries. Or maybe just a new phone... I just really like the camera features and the size of the One mini and mini 2. Then just buy a battery or 2 as backup since it will most likely die.
Sorry it took so long for me to post, lots of things to do. Hope it helps
Couldn't let it go
Scaled down the pictures so they would fit in the post. I have the HQ if any one wants me to post links for them.
So i just couldn't get it out of my head, and still don't want to buy a new one
Either way, i removed the "branding plastic tape" with specs etc to see the "charging?" boards on the batteries.
Here you can see the connectors next to each other so you get an idea of what i was talking about earlier.

}
So the batteries themselves obviously both only have + and - . And they are at equal distance from each other on both of them. So i was thinking about cutting off or unsoldering the board from Mini 1, and solder it to Mini 2 battery. Only problem is... i'm no expert, so i don't know if there would be any issues when charging the phone since the board for the mini 1 is probably made to charge a 1800 mAh battery. What happens if i put that on a 2100 mAh battery? Will it fully charge? Will it even charge or just think "mehh can't recognize this battery, not charging it".
The connector ribbon is on opposite side on the batteries, but if swapping boards, you would just have to turn the battery around when you place it in the phone, hope that makes sense.
But then i got another idea, since i don't know if the board from the mini 1 will work on the mini 2 battery. And that is to unsolder the connector itself from the board of the mini 1. And the solder it on the appropriate pinouts on the mini 2 board.
Going to be hard since they are in the opposite order so i would have to use wires to cross over in order to still have the connector on the right side and not upside down. But that should be possible and not cause any problem, comparing to swapping the boards completely i guess. Again because of the 1800mah and 2100mah, no idea if that's a problem.
Hope it all makes sense I'm trying to write to a few people to get more info about the boards if i can just swap them or if the only way to do it would be to unsolder the connector itself from mini 1, and then solder it onto the board of the mini 2.
I'll keep this post updated when i get some info or when i just go "full retard" and give it go and hope for the best hahaha XD So far if i get no info, i think i'm just going to swap the connectors and not the boards, since i have a feeling that it's because of the charging board that the mini 1 has problems over time (killing the battery) The reason for me to think that way is because on the mini 1 board it is written V01 and the mini 2 board has V02 written on it. That's why i have the "maybe the mini one board is bad and kills batteries" idea. V02, updated, doesn't kill the batteries? i don't know.
Either way hope it helps so far and makes sense, catch you later
Small update... My soldering iron died. Soo i might just buy a new phone and then fix this one when i buy a new soldering iron.
Any help is still appreciated. If any one can explain more in detail why one thing or the other would or wouldn't work it would be nice
I'll post an update when i get to work on it again in case any one else can use this info
Edit: from what i understand so far the best option is to swap the connectors and not the whole board on the battery. Which is really annoying since the soldering spots are small and covered in some sort of epoxy glue. Not hot glue like most electronics, epoxy. I guess you can just swap the boards but the battery will probably not get fully charged since the board is made for a 1800mah battery and not 2100mah.

Trying this weird M-COM brand Battery, Claims to have 5000 mAH

So, I just bought this battery
Probably you guys haven't seen brand like this before
M-COM (Claims to be 5000 mAH in capacity)
Surprisingly this battery have temperature sensor.
I see lot of you guys having problem with battery replacement with built in temperature sensor in other thread.
Bought it for IDR 90.000 (6,5 USD) from local online shop.

Well here goes nothing.
I crack open my angler and recognizes that this battery cable is shorter about 1mm, but it's a no problem for me, just pull a little bit force an viola.
(btw metrics are different here)
It booted up so I try downloading Accu Battery app.
Been using this battery for 3 hours for now, I charge this fella up for a little time and got 4% for 140-160 mAH
Here is my rough calculation
Estimated real battery capacity
3800-4300 mAH instead 5000 mAH
I'll keep you guys updated when Accu Battery done it's job
Any update?

You mind posting a part number? It's about that time on mine, and this seems as good an option as any.

I don't think it have one, i looked both battery and package only seeing plain and branding, sorry.
There's barcode actually (8547182249565)
I heard that barcode are unique to a product but, i couldn't find its use (google won't show anything) rather than pointlessly scanning at them.
That's about right. Thanks for looking.
Hi just curious to know how is it going?
No added thickness? how is it performing?

No thickness added, performs good.
No issue at all. except I forgot to mention that the unit is a bit shorter, enough to make a wiggle inside if you don't stick an adhesive in there so i wedge a folded paper at the bottom of battery slot to keep the battery in place.

It's good, now showing stable 3200 mAh.
You swapped the battery out yourself, I'm guessing?
How difficult is it to do yourself? I heard its easy to crack the camera lens and break a few other parts while doing this and not being an expert, would it be impossible for a first timer? Would I need any other special tools besides pry tool? My N6P battery experience has been terrible.

It is pretty easy to crack the camera lens, so it's highly recommended to buy a spare camera lens part in case the old one breaks. I'm going to be replacing both the battery AND the entire back metal frame soon. Here's a video that demonstrates how to replace both: https://www.youtube.com/watch?v=UetgEdh7mDc

I just replaced my battery and I would recommend getting an X-acto knife and a heat gun. The heat gun helps soften the glue to make it easier to remove everything and the X-acto knife I used to pry everything apart. It took me about 30 minutes to replace the battery.

Yeah a heat gun would make the disassembly much more easier. Luckily I work at this phone booth (for installing screen protectors) and we have a heat gun there. I'm probably gonna do the whole installation at my workplace, we don't get much customers anyways lol.

Hi, BTW this is my 1st post here
Could you please try testing with "Ampere"?
PlayStore: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US
I've used both AccuBattery and Ampere. On my Nexus 6p with original OEM battery it displays:
Max Capaity: 3450 mAh
Estimate Life: 70%
Currently running:
Pixelboot's Lineage 17 with the 4 Core Boot image in hopes that disabling the "4 Big Cores" (ARM Cortex-A57) should help battery life but based on my testing it doesn't help and in fact seems that battery drains faster
TESTING:
Ampere - Power while Idle: min: -220 mA to max: -370 mA
Ampere - Power playing Video: min: -600 mA to max - 910 mA (Only 2 apps open)
Ampere - Power switching Apps: min: -600 mA to max - 1120 mA
To put in perspective,
Battery loss down 1% for every 1 minute
Undoubtedly I need to replace my battery

With all those extra things to buy I'm not sure its worth it at this point as the phone with working parts can be found for $100-150 these days, I'll probably put any cash I've saved twords a future model and leave this as a sort of tablet use with a charge cable handy.

Um well that's basically what my 6P is lol. It's a used 6P that I bought for $90, and am looking to replace its faulty battery and damaged back. In fact, I just did the replacement yesterday. The parts required is not a big deal, it's the disassembly that's a huge pain.
The camera visor and plastic bottom were fairly easy to remove with the heat gun, but the metal cover took a fair bit of struggle to get it off, and in the end it damaged a bit of the display's plastic rim. The hardest part was removing the battery, which was absolutely hell. The battery adhesive is literally glued shut onto the frame, and it takes a lot of force and pressure to get it out. And the dilemma is that if you use too much force, you are risking of puncturing the battery, which I unfortunately did. Waited till next day for the battery to cool down (from the puncture) and I slowly managed to removed it by using plastic gift cards instead of the metal wedge tool that I used before.
Was a tricky experience, but in the end it worked out.
Glad it worked out. I'm terrible with handling these type of tiny electronic components I know I would surely break it heheh.
Be interesting to track your new battery with something like AccuBattery and see if it infact keeps its rated capacity over time. I noticed some bad after market batteries look like there performing well at first and then suddenly the maximum capacity starts dramatically falling after each charge cycle.
