Right I am sick of seeing Samsung Battery's die, not the other day I saw at lest 5 note battery's in one of these recycle battery bins and all of them was ballooned just like mine, I want to use the device without a battery this phone is used as a home entertainment device and 3G modem nothing more, its not used as a phone any more, I want to integrate it in to my Bluetooth speaker would look nice and fit very well.
Problem is I have no idea how to go about doing this without the battery, if there a way to to trick the phone to thing it has a battery or has anyone made a factory cable for the Note?
I feel all companies that make these device to run off a battery only are destroying our world faster as there is so much life left in old android devices if we just could power them from mains power only.
I would like to power it from the battery side if I could so I can still use the USB host but this is not 100% important the 11 gig free on the device and the sd slot will do our home music needs.
Any advice would be great but please don't reply 'get a new battery there cheap', the unit once built wont have access to the battery so making it impossible to keep changing the battery when it balloons again.
Thanks, Rex

For a member with only 5 posts you clearly have no idea what your talking about, how is wanting to give my device a new lease of life
disrespectful? The only thing letting the device down right now is the lag of battery well damaged balloon battery, Housing this with my 50 wat
bluetooth powered speaker would really give new life to this device and how I am using it as a 3G modem I would also like to use the USB host
that this device supports.
I think you should be less disrespectful in your posts next time.

I could use wifi to access content on my network but I was hoping to set up RPI to send the phone to the TV making the device able to also stream my videos to the TV, I am not sure that Android or this device could support multi wifi connections if it could I could do that and also have a dedicated stream for my netflix.
If I can find a way to power all this then I think I will also open a build log post later with all the parts and steps
I was going to use our Acer Iconia Windows 8.1 tablet but the USB host on that is like a wet fist out of water, the android is much better at this task then the tablet.
Recap, I would like to power the device without a battery but via the battery pins so I can still use the USB host.
I need to be able to draw enough power for the device, the USB and Wifi + Bluetooth at the same time.
If any ideas on how this could be done it would be great, I was thinking using some kind of meter to find out what the battery gives the battery circet and then find some kind of multi power block to offer that.

No Android doesn't support Multi-Wi-Fi Connections. (Don't think anything supports that...)
I've tried using Note 2 without charger, doesn't work, probably doesn't for Note either. Though it might work with a socket that supplies loads of power.
Smack that Thanks button if I helped!
KitKat came in on my OmniROM, running on my Note 2.

Yes by default almost all phones don't let your power them on without the battery, but many newer android devices can be powered
by outlet power when in been programmed a factory mode, this is what I am asking people about if anyone has taken the chip of the batter
and provided it outlet power to fool the phone in to thinking its on battery.
You could cheat, find a power adapter and connect it to the battery connectors.
In case OP is still interested I have an idea about this issue. I had exactly the same question, how to power up an android phone without a batery plugged in.
Ignore daedric's post. Smartphones are powered by batteries which, when fully charged, provide 4.2 volts. Power adapter's output is 5 volts, so you would most probably damage your device. Supposing that phone chargers' output was 4.2 volts you would still not be able to use the device because the device draws a lot more current than a charger can provide.
My idea is to use a reliable DC-DC step down converter, and a powerful power adapter. I don't know how much current a Note could draw from its battery but I would try to find a step down converter that could at least handle 3 amps of output without damaging itself. Then I would try to find a reliable power supply like a 12v 2A. The idea is to connect the power supply to the step down converter and the converter to the battery pins on the device. Of course you would also have to set the potentiometer of the converter to output 4.2v.
BUT, there is one more problem. You have to trick the device to make it "think" that there is a battery connected and I don't know exactly how this can be done. I found on the internet a blog where a guy did so by connecting a resistor between the negative battery pin (on the device) with the third pin on the device. So, I don't know if it's possible on the Note, and how to do it. All I'm trying to say is that it might be possible, it just needs more research.

I was thinking maybe you could take the bust battery and like you said use some kind of step down and psu connected to the battery side of the battery's chip thing so that it would provide the right power to the device.

That's a very clever idea. Unfortunately, I don't have currently any old smartphone to try it. In case you try it, be cautious not to short the lithium battery. They can be very dangerous. In case it vents, the gases are very dangerous if inhaled. There's also the risk of fire.
Options have 50 char limit.. So here are longer descriptions:
- Yes. Fast charging is always ON
- Never. My battery lasts the whole day and I (slowly) charge it overnight. And I am either not in a hurry or good at planning my charging time
- Sometimes. I turn it ON only when I need it
- I don't care or know anything about it. I use default settings
Is there an option to turn it off? I haven't seen it. But anyway i use my old s3 charger for all my devices. I don't trust fast chargers. They kill batteries.
Slow charge really isn't that slow.

Regarding fast changing killing batteries the charger provides a voltage to the phone, the power management controller monitors battery voltage and temperature , I would assume these have limits and will take control if outside of range in a similar way to throttling cpu frequencies when it gets too hot.

I'm using "bad" cables for show charging but being able to limit the current and the charging state without root, like on Sony smartphones, would be great

The option is in Device Care > Battery > Settings
Personally I leave fast charge turned on and use a bunch of different chargers with the phone, I just have Battery charge limit set to stop charging at either 80% or 90% (depending on when I think I'll be next able to charge) and try to start changing between 20% and 40%.

Using "bad" or cheap cables is really not the best idea, they often don't meet the USB C spec and could damage your device. Try to stick to high quality but low current chargers (Like old phone chargers) or disable Fast charging as previously mentioned.

Strange. My n9600 doesn't have that. I got device maintenance and there's some battery saving options in there but no fast charge option. Oh well the s3 charger works for me.

Under the battery menu press the three dots in the upper right corner and select advanced settings. As for the poll I turn mine off.

It's rooted. I did come up with a solution using the Automate app and a smart plug a little while back but only worked if you're charging from the charger that's plugged into the smart plug.
Yeah okay this 2 ways are well known
Thanks for the fast reply ^^
I was already questioning my eyesight. You know, Samsung UI and not finding an specific setting in menu could happen even after years I think ^^
I charge when I want, as fast as I want. I leave it on the charger overnight, everynight. Have done it this way for years and will continue to do so. Never seen I'll side effects from doing it this way. I have too much of a life to monitor my charging speed and make sure I'm next to the charger to stop it at 80%. I like waking up to 100% and using it as I see fit through the day. YMMV
Fast charging is set to ON by default straight out of the box. So youll think samsung has taken this to consideration.
Personally, i keep this off when charging with the orginal charger. I have an app called Battery Warner which alerts the user when over a set %. or if rooted it will stop charging and enable charging when it is under a %.
If i have plans to go out and the battery is low then ill throw it on fast charge.

My 2 cents:
I think Samsung doesn't care much if battery will remain healthy after 2 years. They care now to sell as much Notes as possible with the "Fast charging" marketing slogan.
That's why it's ON by default.
I never use fast charging as it will provide more harm than benefits to the battery health + I use a magisk module (Advanced Charging Controller) which have cooling mechanism and voltage monitoring and also battery temperature monitoring and this will also greatly increase the battery life on long term use.... since we got a non replaceable battery
Since I rooted my Note 9 on day 1 (I don't care about warranty) the first thing I did is I used Advanced Charging Controller and keeping my battery healthy for as long as maybe 4~6 years of usage

It does, but still the degradation is higher vs no fast charge.
on the topic: The first thing I did on my s7e was to turn off fast charging - the battery after 2.5 years is in a really great shape even after every day charging. The same I did on my note 9. Will use fast charge only if I am in real hurry and need a lot of battery fast. If the phone is changed every 2 year tho, it's not that big of a deal and everyone decides for himself.
Otherwise in most cases it's not needed to charge overnight as 0-100 without fast charging is 2h-2h and 10 minutes. As most charge from ~20%-100% it will take 1:40 to charge the phone. The overnight charge is if the phone is charging from the PC USB - the best way for battery longevity, but not really worth the hassle vs normal charger charging.
According to poll results: more than a half (or 2/3 depending how you will count) uses fast charging.
No, slow on cable and fast charge for wireless!
Photo's by Sully using SM-N960U
The high temperature is an enemy of the li-ion battery. The normal load on the cable drives the temperature to 30.5C. Fast charging on the cable tray at 34.5C. Fast wireless charge up to 37.8C. What better?
Never have and never will use "fast" cable charging. I dont wireless charge either.

do rooted/custom roms enable this or is this a hardware limitation? I understand its a temperature related issue. I am not saying fast charge while using overlclocked cpu and playing games. It just seems a tad annyoing that i cant charge my phone while driving in my car and navigating at the same time. (it will charge but only so very slowly....)
i am talking about the "adaptive fast charge" which really only fats charges when the screen is off or in AOD (always on display)
When you, lets say, have google maps open while driving the "fast charging indication is actually lying to you. It will only draw about 5 Watts there.

I see someone wants to recreate a newer Note 7. I don't think is is a hardware limitation, of the physical phone or the stock charger, but the (stability of the) battery itself. Playing a game at full brightness would require adaptive fast charging to generate too much heat in the battery itself to compensate for the rapid battery drain, and maxing out the factory charging cable to replenish what was lost during current use and charge the phone in the same quick time you are accustomed to (with the screen off).
You are really asking another Note 7 disaster

haha not quite. i think you are confusing some concepts here. The net energy / charge arriving at the battery is actually less when the device would be under full load because the device itself uses a portion of the energy supplied by the charger... or am i missing something?
I think the gpu/cpu/screen heat in combination with charging is what the issue was on the Note 7. The battery itself can, as it might be obvious, easily be charged with ~15w. I believe the smart solution here would be to simply reduce/throttle charging with relation to CPU/battery temp.
I can tell you that when in a holder in an air conditioned car using google maps the battery will be fine with quick charge unless there is some weird coupling between two ICs.
Any decent quality USB cable will not be a limiting factor. 2 Amps @ 5V or 9V is really not a problem/
My measurements with the factory cable and charger at about 85% battery were around 1 Amp @ 5 Volt with screen ON and about 1.67 Amps @ 9Volts with screen Off or AOD on.
anyways. really only wondering if custom ROMS support this is or not. having my phone quick charge in my car while navigating is very important to me.
I think Samsung just played it very very very Safe after the Disaster. Limiting current and battery size that a guy who quick charges his phone in a Sauna can play candycrush on max brightness in performance mode....

Samsung smartly chose to avoid the issue altogether.
Heat dissipation will be that issue to contend with in my opinion. My phone's charger only does 18Watts on a good day (screen-off) in an airconditioned room (measured by a USB multimeter). There needs to be adequate overhead left in the thin stock cable that is shipped with these phones (which isn't even USB 3.0).
I believe that this maybe an safety feature built in by Samsung in the wake of the Note 7 battery issue. There may not be a work around for it.

You aren't helping the OP's case in trying to re-create another (explosive) Note7. Suggest something nerdy, like creating a custom kernel that tricks the charging circuit into thinking that the screen is off when the the charger is connected.
I have a QI wireless charger in the car - if I dock my Mi 9 it charges fine, but then when it gets to 100% it turns the screen on.
I think it then stops charging, and then a small amount of battery must be lost, then it charges up again - gets to 100% and then the screen turns on...
And repeat!
So once the phone is at 100% its turning the screen on and off every minute or so, very frustrating when driving.
Is there a way to suppress this anyone can suggest?
Thanks,
Bill.
Nobody?

Unfortunately I've no solution for you, but indeed this sounds a frustrating issue! Furthermore, when i have my phone on the following wireless charging stand at night time....
https://www.amazon.co.uk/gp/aw/d/B07KG5HDFX?psc=1&ref=ppx_pop_mob_b_pd_title
...i don't face this issue. As in, I have it charging throughout the night and I haven't noticed it turn on and off when reaching 100% and the repitition you have mentioned.
My only suggestion is to perhaps try another wireless charger, though this may be slightly over kill as perhaps the same thing might happen with that one. Presumably the charger (or phone?!) is stopping charging at 100% then dropping to 99% and resuming charging etc. Which charger do you have out of curiosity?
I don't believe there are any settings currently that can help you. There is a setting in the Developer Options, but the opposite "keep screen on whilst charging". Therefore whilst this setting is not what you need, reporting this feedback to Xiaomi could result in a new setting to "disable screen on when 100% charging complete" could be implemented.
Do you intend on unlocking your bootloader/rooting etc? As you could ask for such a setting to potentially be implemented into the Xiaomi EU rom or other custom modified rom. Alternatively, when (hopefully) we start to get roms like AOSP etc with lots of features. Lastly, perhaps the best option for you would be to use something like Tasker (rule based automated task app, Google it if unfamiliar), if you do intend to root, as I believe you could use a rule such as "when charging = screen off", which may work.
I got that idea from here:
https://www.reddit.com/r/GooglePixel/comments/9wg8k5/is_there_a_way_to_have_the_screen_off_while/
Same issue here, but on wire. Screen turns on, showing the charging animation, then goes off for a while, then turns on again. Frustrating.
Update: I figured out that the phone 'doesn't like' some chargers as I use many. I have an older 5V 1A Huawei charger and the behaves like above, however, with other chargers it works fine. Previous phones work fine with this chargers too.
Hi, i have Redmi Note 10 Pro (sweet) and from 3/4 days i have facing fast charging (phone says fast charging) slow, 3 hours for charge fully and if i check with battery guru says max 5w output, official xiaomi charger and tried also with baseus 120w charger, before works well fast charging, any suggestion? other with this problem? Unlocked with latest twrp from nebrassy and MIUI Rog edition with delta kernel
Can you confirm that the phone is actually taking 3 hours to charge? Or is it just saying 3 hours until full? My phone was also showing 3 Hours Until Full but in actuality was not taking that long.
Take me about 45 minutes from 30% to 90%, it should be about 1h30m for 0 to 100%
try changing the orientation of usb-c connector on either or both charger and phone connection end and see.
I have no problems charging close to 33W with Xiaomi included charger or my Baseus 65W GAN charger which supports 33W profile. I charge at around 75%/hr
Looks like a problem with twrp /
Go to the concerned forum with this question
If you have Magisk / Super user, they have modules to enable fast charging
Probable cause might be your charger cannot detect the charging profiles supported by your phone. For precaution it uses the slowest profile.
Also you may check with the kernal. Sometimes they purposefully disable fast charging.

I flash a known good rom as charging issues are hard to troubleshoot... reduce the variables.
Or trouble shot the current firmware if you are capable of doing so. The wrong value could cause hardware damage.
Could also be a sign a hardware fault condition exists.
Inspect port with a good light and magnification for any signs of damage. Clean if any debris or dust is present.
Use a known good OEM charger and cable. That means exactly what it says. It's also how I ended up with 2 Samsung bricks/cables
A friend or repair shop might let you use theirs.
Did not root my last two phones anymore. To much problems ;-)
Camera Api2 is activated by default on the 10 pro. So bootloader unlocking also not needed.
