[Samsung Galaxy S10e Questions & Answers] YoungPumpkin:
Ohhh. Then battery is ur only way of waight reduction or maybe if u find a custom plastic back. Thx for your help anyway.
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
The s7 edge had a 3600 mAH battery , 100 plus than the s9 , and if ur into desoldering, you surely could do it , and if you do, post a guide as well .
[Samsung Galaxy S10e Questions & Answers] YoungPumpkin:
I think soldering the chipset of the battery isn't the problem. It has to fit or at least almost fit without destroying the chassis too much. I"ll check the dimensions of the batteries and compare them.
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
Back in the day they used to swap the s7e's battery onto S6 flats , so surely you will find the proper dimensions for it , also the phone is a tad smaller than the s9 , close to the s10e's dimensions so by that logic, the battery should fit better ?
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
here's something to give you an ideea about soldering the connector thingie on the other battery Battery connector swap
[Samsung Galaxy S10e Questions & Answers] YoungPumpkin:
the soldering part is the easy part. I'm worried the battery won't fit because of the size. s10e's battery is roughly

I just noticed there is a code on the battery that determines its size 1/CP6/44/77 [s10e] and that's where it bottles up.
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
damn, s10e's battery is THAT small? pff, what's the size of the s9+'s then ?
[Samsung Galaxy S10e Questions & Answers] YoungPumpkin:
i think the s9+ is pretty close
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
Maybe if you flip that top connector , in case it is flexible , then there shouldnt be a size difference issue .

Also dont they make the cutouts for the batteries bigger now, to allow them to expand (since the note 7 issue ) ?

Let us know of your progress, I have an s10e as well & it's brand new for now, but if you manage to get a bigger battery in it, i will open the back glass too .
[Samsung Galaxy S10e Questions & Answers] YoungPumpkin:
I was planning to upgrade the battery when I bought the s10e the second time but I wasn't sure so I opened the form to talk out the possibilities. as of right now my battery isn't that bad but when it does get bad I might upgrade because I like the form factor of the phone.
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Hey there,

I've been searching around for a topic like this since forever now, only thing i could find is a YouTube video which wasn't clear enough.

Since my battery health was already dying on s10e i thought about an upgrade instead of replacement but couldn't find similar dimensions to s10e's battery.

Then i got a juice pack but it made the phone bulkier and the continuous charge would heat up the phone + increment on the charge cycles of the battery.

Already tried s9+ battery but it doesn't fit in the frame horizontally

Though vertically it was a perfect fit and a bit thicker overall

I replaced the complete pcb, removed the battery's covering and adhesive strips , didn't make much of a difference either.

I've contacted a lithium ion battery manufacturing unit located in china

Who make custom batteries with your preferred dimensions but in Bulk and they were ready to ship 20 pieces for 7$ each .

But i highly doubt their performance or long term usage when compared to the Samsung manufactured ones .

Also you'd have to desolder the current pcb from your phones battery or else source PCBs from china in bulk again .
[Samsung Galaxy S10e Questions & Answers] YoungPumpkin:
How much battery does it stick out horizontally? And what would be the custom battery capacity? I think the only option is a s9+ battery to my beliefs.
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
Can you share some pictures or the video perhaps so we can have a look at them ?
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
I've managed to get some exact measurements from some sellers for the s9+ battery

78 x 40 x 5 mm

Also they have sent pictures & from the picture , the width is more around 45/46mm rather than 40.

Mister GoodTunes said the s10e original battery measures 42mm wide, and 71mm tall +5mm circuit piece , so we have a 2mm difference in height , which could be adressed by bending the circuit piece for it to slide in place but looking at his picture with the open back, there doesnt seem to be an extra of 2~4 mm on the sides to accomodate the width of the s9+'s battery, at most 43~44mm .
[Samsung Galaxy S10e Questions & Answers] emadhamid:
It's about night time and i don't have the s9+ battery here.

Since i had only stock s10e battery i had to put it back into the phone.

I'll still be posting the s9+ battery pictures tomorrow for your convenience even though no point of trying to squeeze it in the s10e frame

the height doesn't matter there's a little bit of room like 4mm( top and below for expansion) s9+ battery easily squeezes in

it's the breadth which you'll have to look after and i don't think even after we somehow modified the frame we can glue down the back glass because of the thickness, unlike samsung s6 where it wasn't much of a difference and one could peel off the stickers from the battery to get more room.
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
In case anyone has an open back S10e , could you please post the exact measurements of the battery compartment , in milimeters. Thank you.

Late update , a user on reddit said the measurements are : 43mm x 78mm , this means we need to shave off 3mm from the width of the S9+ battery or modify the battery compartment for it to fit. Judging by MrGoodTune's picture posted on page one, there should be space on the opposite side of the motherboard.

What do you guys think ?
[Samsung Galaxy S10e Questions & Answers] emadhamid:
The dimensions of the battery cave are exactly as 80 x 45 x 6 mm

Anything lesser than that will fit perfectly
[Samsung Galaxy S10e Questions & Answers] emadhamid:
And i did aswell find a s10 replacement battery (which is usually not that good and shrunk in size than the original)

It fit very well in the battery compartment but I'm sure it won't make any difference because it's just 300mAh extra (minus the 20% non original performance which makes it as worse as my stock 2 year old battery is)

I'll still be using it for sometime and keep checking the battery health regularly then post the results

*Note: The original s10 battery from samsung won't fit even if you bent the circuit board
[Samsung Galaxy S10e Questions & Answers] MrGoodtunes:
So, @emadhamid - You are using an aftermarket battery for S10 in your S10e. Congratulations! How did you deal with the circuitry at top of battery; were you able to use what came with the battery including ribbon connector as is, or did you detach it and replace it with S10e circuitry and ribbon connector?
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Hello,

The BMS on all of the S10 series are identical

And the connectors are the same .

So you can literally swap batteries of one with another.
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
This is great news you guys, congratulations for the findings .

Now, if only there was a way to modify the back glass and have it perform like the back covers did back on the S5 and previous models that had swappable battery. This way we'd have a hot swappable battery phone as I'm sure there are ways to charge the batteries directly.

Is anybody reading this that's good with designing STL 3D printed files , to give it a go at making a layout or a sketch for the design that we could use as a plastic cover for the phone ?

Worse case scenario I guess we could use a hard shell/tpu back cover for the phone.

Check this out to understand the ideea :
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Since the idea seems fancy and innovative it isn't practical todau . you're forgetting some key details of the hardware.we barely shutdown our phones these day and keep many multi tasks running in the background .

1)Batteries in a phone are charged with the help of software , simply plugging one out and popping one in won't callibrate with the phone's software (although all of the phone batteries charge at same voltage)so either the battery will stay at 0% and phone will start prompting you to charge constantly but staying alive worse case scenario ,battery jumping 60% - 40% -30-10 and staying at 10 for the rest of the day.

2) making custom back panels : it will be pretty easy to make one but whenever you try to replace the battery you've to have a screwdriver with you .

3) you can't charge your phone without the wireless charging module , means you accidentally rip it off or tore it's cable ,be ready to buy a replacement one .

4)the internals of newer phones need to be cleaned thoroughly because they're not meant to be exposed (waterproofing) , and everytime you touch the camera sensor you degrade it's quality.

A better way would be to make a custom case which replaces your back cover completely , has room for bigger battery keeps the thermals of your phone adequate so that it doesn't blow off when you're charging it.

Like a juice pack but it doesn't charge through your port instead connects directly to battery connector on motherboard
[Samsung Galaxy S10e Questions & Answers] emadhamid:
something like this but permanent
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
What's wrong with just using a battery case all the time?

I looked for a bit but the only ones I can find in my area are questionable chinese ones and we dont trust those around here as they are known not to last very long .

But then again, leaving the phone alone & intact, how hard would it be to just modify the charger case and swap/improve the batteries on that, benefiting from the case's charger module that goes into the phone and just modifying the battery itself ?

I can think of the issue that the battery case wouldnt charge the phone fast enough as the phone's battery depletes so it would require a fast charging case I presume.
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Using the battery case all the time . Pros and cons:

Your phone will remain charged all the time and could last days with regular use

Your phones charge cycles will raise ending up in low battery health or battery backup ,the moment you take off the battery case your phone will die (or maybe last an hour)

You don't need to tear up your phone which causes potential damages or harm it's warranty if you're using a battery case .

Your phone becomes double it's size like a chonky cheese brick ,no longer compact.

Your phone will heat up most of the times because it'll be charging which will drop the actual performance.

Situation:

1)Modifying the battery case:

The only way i can think of rn (as a designer and engineer) is to remove the charging port from it and add a wireless charging module coil .

Not that expensive but still causes heat. It's just that your charging port won't be busy all the time . + Charging will be slow so it won't hurt the battery cycles that much .

2) MAKING YOUR OWN CASE but this time around it doesn't charge your phone .but it's just a battery with a bigger size and mAh which connects directly to your phones motherboard. + Batteries are not Chinese but your original Samsung ones(literally any battery from samsung A or M series.

You Could also connect 2 iphone batteries 6,7,8 in parallel just because of their sleekness and durability)

It doesn't need to be as thick as the battery case because it just contains a battery.

That's the easiest way of all

I'll try to make an illustration of it soon . Until then check this video out :

This might seem a little bit complicated and ugly but once you figure out what needs to be done

You'll master it within a day .

Also you need to keep the phone as compact as possible so 5000mAh battery will be enough.so it doesn't look like a brick like that of this guy .
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
Loved the video and the whole ideea in general.

Now, you said something about the wireless charging module coil. I have an S7 and an S6 lying around and they both have the wireless charger thingie on the back, is that usable ? I mean, could we use that, like stick it on a battery and bam, we can charge from that battery ?
[Samsung Galaxy S10e Questions & Answers] emadhamid:
No sorry, there are mainly 3 parts to a wireless charging module

The receiver (which is most likely found inside your phone )

The transmitter and the control board which are found in the charging plate . transmitter is the thing you're looking for if you're planning to make a wireless battery case.

Not very easy to source one(but in bulk) for a powerbank/battery case because the circuitry needs to be as minute as possible to take the least space.

I've already sketched some models for the back cover case. Now i need to make a 3D one with proper dimensions. once they're done I'll put them up here and then I'll need someone to test them out because 3d printers are still rare in my country and ordering from commercial sites will take ages.
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
Good luck with that Hamid ❤️

You'll be doing important work for the modders later on

I can only find these two battery cases in my country and I dont think they come with wireless : This one and also this
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Just gave a look at these battery cases . They seem like Chinese knockoffs of Mophie ones

And they do write 5v 1amp in their description.

That's slower than a tortoise. Don't go for them.

Only if there is no other option left you can just buy any of them and try to replace the board inside with a faster one(hundreds are Available online)

The battery in them though may or may not be as big as specified.
[Samsung Galaxy S10e Questions & Answers] emadhamid:
After hours of sketching i figured out that it's better to make a custom back panel with a hollow space for a battery or second battery than to make a phone case .

only cons are :the phone will be less protected because you won't be able to fit protective cases. and you'll have to say goodbye to wireless charging.

I'm making one which has 55mm X 90mm X 5mm hollow

90mm height at the most because the Biggest battery i could think of fitting into the phone is s7 edge 3600mAh (BG935ABE)

Connecting 2 batteries will be even better option

How to connect two batteries at once : you've to remove the BMS from the second battery

And solder its terminals in parallel with the battery you're currently using (+ve to +ve and -ve to -ve)

Any suggestions, questions,doubts , please feel free to ask
[Samsung Galaxy S10e Questions & Answers] emadhamid:
How to do it:

Basic Soldering needed

By connecting in parallel Voltage will be the same only the capacity will increase .
[Samsung Galaxy S10e Questions & Answers] MrGoodtunes:
Many thanks @emadhamid for the six pics re batteries in parallel; good way to go for lots longer battery life. As you may know, my interest in this thread is different; I want to reduce the mass of my S10e, and do not need stock battery life. Thanks to your pics, I have done work on a dead S10e; removed it's battery, and began mocking up a much smaller battery from an old HTC.

Flipping over the S10e battery, there are indications for [+] and [-]. It's a little different in that the negative terminal is the one closer to the mother board connector. I verified this polarity is correct using my VOM multi-meter. Meanwhile, I hack'd the 4-terminal battery contactor piece off from the old HTC.

Just one sort of big hurddle left for me to get over; namely, soldering wires between BMS ribbons and very tiny terminals. I've done lots of soldering, but mostly speaker wires and automotive connections. My soldering iron is old and bulky, making this type of work a challenge for me. Laid in some wires; will probably trim, and then solder when I feel up to it.
[Samsung Galaxy S10e Questions & Answers] emadhamid:
I don't know why would you do that . Putting two BMS in a phone .

You would probably need to remove one of them if you can't work on minute soldering or the flex cable.

Put the battery on a metal sheet or any type heat conductor like a marble or tile.will help with heat management.

Tin the contact points on the BMS on your HTC battery

And then on your s10 BMS..you should be able to run a thin wire to the terminals ,just be sure about the polarity .

But in the pictures i can see you've ripped off the connector from the htc phone and want to place it in s10 to make it removable.

Then you'll probably need to find a way to connect it to motherboard points instead of your BMS terminal.

It's a heck lot of complication...

Best of luck for the soldering mate 👌
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Hey man i read all your old comments about downgrading the battery because of weight issues.

And now i understand.

You could get custom lithium polymer batteries from anywhere around the world and just need to solder their pre made connections onto your s10 BMS terminals.

Available in all sizes and cheap too

Looks like these
[Samsung Galaxy S10e Questions & Answers] MrGoodtunes:
It took me awhile to finally manage soldering wires to the sort of foil tape battery input connections of the S10e battery circuit board. The foil seems to be covered in some kind of rubbery plastic or maybe adhesive. You can see a string like bit of it hanging up on the cut off left foil terminal:

Used a razor blade to scrape whatever it is away to get to bare metal, being very careful to not mess up the really thin metal foil. After that, my solder joints worked. So I have reduced my S10e's mass by 22~23 grams, bringing its weight down from stock ~5.3oz to now ~4.5oz.

A huge thanks to @emadhamid for important information and support.
[Samsung Galaxy S10e Questions & Answers] okij:
Hehe, MacGyver at his best. 😄 Thanks for sharing your experience and pictures.

I'm just wondering why you want to save 22~23 grams? IMHO the S10e is not too heavy anyway, even with a back cover and a screen protector.
[Samsung Galaxy S10e Questions & Answers] MrGoodtunes:
Actually, I want to save more. It's still too heavy; maybe I'll try hacking out the now unnecessary lower half of its battery box. There are many reasons why I prefer lighter phone:

(1) I'm fairly active, run alot (e.g. from parking lot into grocery store). Heavy phone tries to break its way out of my pocket. I hate that.

(2) The feel of a heavy phone is as if I'm holding a dense slab of lead. I hate that too.

(3) Heavy phone always feels like it's gonna slip out of my hand, has to be held tight.

(4) My 1st cell was an HTC Touch weighing a bit over 4oz. My 2nd was an S4mini weighing a bit under 4oz. I still love them both, would be using S4mini if only some carrier here would support it. I could go on, but it'd be more about personal preferences.
[Samsung Galaxy S10e Questions & Answers] okij:
@MrGoodtunes Thanks for your explanation.

For me personally the weight of the S10e is totally OK and I'm glad to still have the original battery in it with the housing still being IP68 proof. My first Android phone was the Motorola Defy+ which was even smaller than the S4 Mini, however a bit more than 4 oz in weight, but (special for its time) IP67 proof.

Remember to put Helium or Hydrogen in the space that your smaller battery doesn't fill, so your phone gets even a bit lighter. ;) (But then you also need IP68 sealing to keep the gas in the housing. 😂)
[Samsung Galaxy S10e Questions & Answers] MrGoodtunes:
Update: I have moved on from the HTC battery; been using a 1000mAh lithium polymer battery for over a month now. No low battery issue at all. For my next experiment, I will try 500mAh.

Anyone else finding success with battery work?
[Samsung Galaxy S10e Questions & Answers] CurlyBlonde:
What about if you could get somebody to 3d print you the middle part of the phone, the one that's made out of metal, surely that's the part that weighs the most in the phone along with the display itself.

But if you got that printed out of plastic or whatever they use in their 3d printers, surely that would weigh less so you could get an even ligther phone since you dislike the weight so much and are willing to go to such extremes to achieve smaller weights in the phone.
[Samsung Galaxy S10e Questions & Answers] MrGoodtunes:
Thank you @CurlyBlonde for your interest, and especially for encouraging @emadhamid with words that I believe were instrumental toward his sharing of crucial battery information.

I did go ahead and strip my 1st (dead) S10e down to its frame, hack'd some out, and put my 2nd (daily use) S10e parts into it. From what I could tell, Samsung used a combination of lightweight plastic and fairly hard alluminum (versus soft bendable) for the frame. They really beef'd up the battery area, as if they're still worried about the dissasterous S7 battery explosion issue. I removed material from several places, including a good chunk of thick metal, which you may be able to see on the left side of this picture.

Also, since I pretty much have to use a protective case anyway (and have given up original water resistance, which I do not need), I broke away most of the back cover. Found it is made of safety plate glass, i.e. TWO pieces of glass with a rubberish sheet sandwitch'd between glass plates! And while re-assembling, I left the annoying vibrator out; it's an electric motor with a lead weight to make it spin out of balance. At this point, I can finally say that I love my S10e (even tho some people are probably laughing at me).
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Hey mate

Good job

You've perfectly cut the midframe

Loved your passion throughout this time

You could go for paper batteries for next experiment but guess they're on beta and expensive side for now .

Other than that I'm glad you're finding spaces in this already packed frame

👍
[Samsung Galaxy S10e Questions & Answers] emadhamid:
That's a lot of work and also time consuming project , 3d printed materials (resin/filament) are not strong enough to hold the parts together, moreover the antenna integration into the frame is a big mess .

Such complicated 3d prints are never perfect
[Samsung Galaxy S10e Questions & Answers] greenmatrix:
Sorry to resurrect this somewhat old thread...

@MrGoodtunes, amazing work! Are you still using the S10e, and what kind of battery life are you getting out of a 500mAh battery? Are you underclocking the phone or doing anything special to preserve battery life?

@emadhamid, did you ever finish your idea to fit a bigger battery, or two batteries connected in parallel with a custom back?
[Samsung Galaxy S10e Questions & Answers] MrGoodtunes:
Yes, using my S10e daily with the same 500mAh lithium polymer battery for almost 2 years now. Battery life has been totally sufficient for all my usage; it drains sort of quickly when i use it for resource intensive tasks, but it also fills back up very quickly even though I use old low voltage and low wattage Motorola chargers. I recharge regularly, often using the device while on charger.

No, I am not underclocking; in fact, I have Enhanced Processing turned ON. There are many things I do to keep battery usage low. For example, since SOT (screen on time) is a huge battery drain, I use an old app called Soft Lock Screen which makes it quick and easy to turn off the screen whenever I'm not needing it. My default home screen, Apex Launcher Classic, is set such that the screen goes off when I double tap on the middle button of Android's bottom navigation bar. First tap takes me home, second tap launches Soft Lock Screen. The screen goes black instantly, and phone goes to sleep soon after that.
[Samsung Galaxy S10e Questions & Answers] emadhamid:
Hey ever thought of a debloating the system completely, search UAD ADB on internet, remove all the unnecessary apps including bixby etc
