Think about it. Do you really think a battery of that type and size could safely absorb that magnitude of energy? Picture yourself holding a 100 watt incandescent light bulb with bare hands.

Are you serious? A battery is storing energy, not using it which would generate heat, as an incandescent light bulb is! Think about that!
Full disclosure - I own a Mi 10 Ultra and when I charge it at 120 Watts it doesn't get hot!

Electricity/energy is never 100% conversion into electricity/energy in between anything. It always generates heat.
It doesn't get hot because you don't feel it. Your hands are not a thermometer. It's subjective.
Use built in apps like Ampere from Google play to check about battery status.
It should show you the temperature measure by the device itself of the battery and the charging speed in milliampere.

Let's see you put your hand in boiling water! of course, my hands respond to temperature.
Or how about holding a turned on incandescent bulb?
Correct charging is not 100% efficient and that's the part that makes heat, whereas an incandescent light is 100% heat, so really not comparable.
Measuring amps into a phone or battery will NOT give you the battery status on its own, you also need the voltage of the battery. In Xiaomi mi10 Ultra case the charger supplies 20V @ 6amps which is split into 2 batteries and converted to the charging voltage of the battery (around 4.2-4.7Volts). Doing a balance of the power input and the heat generated will give you the conversion or charging efficiency (Physics 101). The same with temperature, you need the mass of what you are heating to know the heat input, which also needs to know the losses and isolate the device from the environment. Temperature is not a measure of energy on its own.
I do not believe an app from wherever gives you this, it just can't physically measure it. Even the Amps indicated come from a sensor, which uses what to measure? Hall effect? what is the accuracy and losses.
There is a chip inside the charger and another inside the phone that adjusts the charging according to the capacity of the charger and the phone battery status as well as the ability of the phone to take the charging voltage and current. This is defined as part of the quick charge specifications.
An Engineer has designed, calculated, tested and modified these devices over a long development cycle. they work and don't get hot.
It's a graphene cell, a smartphone first.
It's very energy efficient and charges faster then a bat out of a Wuhan lab, with very little heat.
I want a graphene retrofit for my 10+
Bad behind the curve Samsung... what's wrong did the Note 7 baked your balls?

Having a fever now. Come and measure the temperature. 36°C ? 37.5°C ? 38°C ? 39°C? 40°C?
Can you distinguish it? When you want to say you can, the scene is you are also having a fever. Can you still distinguish?
That value is measured by the phone itself. You don't feel it when it is behind a cover, a glass, because Engineer work hard to not let you feel it. You are not touching the battery itself. How do you know it's not hot? Can you distinguish that way?
At least take out an Infrared thermometer and measure it, to be better objective.
First tell if your phone can work properly at the temperature of boiling water or incandescent bulb.
So really not comparable back at you.

Of course voltage and current. Battery status was measured by the phone itself.
Observing current to know what state it is, fast charge or normal charge, along with battery percentage.
Look on the 33W charger, normal charge is 5V⎓3A
At normal charge, for sure the voltage is 5V, so current is the thing matters of the charging at that state. (This is for energy efficiency, high voltage low current has lower energy loss than low voltage high current.)
Fast charge is dynamic, so it's not easy to know, but on the charger, it's 3⎓1.35A.
Just observe the battery percentage and current, you can know if it's in fast charge or normal charge.
If current measured by the phone is below 3A, but the percentage is rising fast, like 40%~70% in 30minutes, it's fast charge obviously.
If current measured by the phone is below 3A, but the percentage is not rising as you can feel, it's normal charging.

Phone need to know itself what percentage, voltage, current it is charging, and base on that to adjust charging.
App just took that measured value out and show it to you dynamically. Even if you don't use the app, you can still check for those current, voltage and temperature on your own. It's designed in the system.

Agreed Engineer had adjust them, but it ALWAYS gets hot.
They are only adjust to the point you don't really feel it under the case or glass.
Take Infrared thermometer and make Video to show it don't get hot. Then will believe it.
Remember, measure the naked battery, not over the glass.
Internal resistance causes the heating. That's a lot of watts flowing through the relatively small copper buses. Graphene is a better conductor than copper but still offers some resistance. These batteries are cool and could easily last the life of the phone.
Graphene is 1.4 times as conductive as copper by volume, but if you factor in density, it is 5.8 times more conductive (if a given sample of copper can carry 1 kA with a 1 V drop in voltage, the same weight, and length, of graphene, could carry 5.8 kA with with a 1 V drop in voltage - in theory).
Maybe you are right, but my engineering training and 40 years of experience says no that's not correct.
How about you proving that the battery gets hot on your mi 10 pro.
Give us a video and thermal camera video of the temperature rise as surely that is proof that it's worse than a mi 10 ultra.
Looking forward to your proof.

4 terminals...
one plus..
one minus...
what are the other two? I read the service manual but didnt see anything.
Typically Li-ion batterys have the extra terminals to communicate with the battery about certain conditions of the battery. Typically it is connected to some thermisistor which is a resistor that changes resistance based on temperature. And it uses that change to calculate the temperature of the battery, because if the battery gets too hot it could explode. Li-ions are susceptible to thermal runoff which is why most incorporate this.
So after looking at the teardown and assembly info online, I've started to percolate a notion in my head to double the battery capacity of the NC.
My thinking is that if you sacrifice a bit of structural reliability by cutting out the portion of the plate the battery is on, you could cram another NC battery, scavenged from the ruins of a dead one, into there and wire it in parallel. The end result would be a heavier, probably slightly girthier, NC, with 8000mAh of life. I don't care how bright your screen is or how many rooted roms you're using, that fool will last a looooooong time.
My question is primarily for electrical folks here: any pitfalls to watch out for? Do we know if there's any circuits in the battery itself that might interfere or is the battery unit just a collection of Li-Ion packs?
Of course if you think I'm a mad scientist who must be stopped at all costs, please feel free to chime in too. Just stand over there on the scorched X on the floor next to the death ray...
Hmmm if the kernel allows for a charge higher than the one its in now. Like the evo charging issue with extended battery

Like he said: Whaa? I had an EVO [fun] but couldn't stand the less than less-than-stellar battery life. I'm talking dead by 4pm crap. Bought an extended battery and noticed no improvement. Is that why? Finally downgraded to an EVO shi[f]t [less fun] but I'm not getting the kind of improvement I would've expected going from a 4.6 to 3.6 inch screen, after all aren't they the biggest battery sucks?
sounds too scary for me!!! I think I'd rather just replace the battery (if it is possible to purchase one...)
The main issues would be....
1. extra strain on the charging circuit.
2. the possibility of battery imbalance...leading to extra strain on charging circuits...possible overheat...boom
3. possibility of overheating due to combined heat from 2 batteries during heavy charging...boom.
make sure all of those are taken care of and you are golden. Personally, I would source a larger amperage battery with similar dimensions and wire it in.
I like the idea, carry on

I have one of those, and yes it will charge the Nook Color on the go.
Just a little heads up on the topic, android stores battery info in the boot partition I believe and that's what tells the kernal the status of the battery, I.e. a double capacity battery would report as fully charged when only half charged if you didn't Pachelhoffer the is/kernal and such to match the new capacity.
Correct me if I'm wrong!

These are excellent points. I would avoid hacking the internal circuitry and instead get a hold of an external battery, design a circuit to drop the voltage to 5v and use the usb cable to charge up the battery. Trying to charge two batteries in parallel is asking for trouble because of the imbalance problem.

For the price, I got the XP1000 I think (its in my backpack which I left at work) I actually got it for my Epic to charge when I was out and about and moved around too much to use a wall charger. Works on the Nook too, but I haven't tried a real charge to see how much I get out of it. I would guess if I can charge my Epic 2-3 times that I could at least recharge the Nook once completely.
Warning - be careful screwing around with the internal LIPO battery and circuits. If something damages the single cell battery or voltage gets to low, and you try to add voltage and amps to it, it might puff up and if it does its flammable!
Its a single cell LIPO pack like used in rc airplanes and cars! They are very finicky to say the least when it comes to discharging and charging. Let alone if you want to hook up another one to it and do it wrongly! People have burnt down there whole house at night just over charging one and not babysitting the charging progress!
It is a lithium-polymer battery and not a lithium-ion!
They can catch fire when they puff instantly, many videos on youtube!
Correct me if im wrong, but the battery has a built in monitor and charge stopper so if you were to charge both the batterys via the micro usb slot you would need some sort of trickle charge/sbc kernel mod to overcome this which could be a real pain in the arse and not to mention dangerous considering trickle charge has been known to damage batteries on occasion and we do not have an easily replaceable battery.
I have this unit, http://www.amazon.com/gp/product/B0038VQET4. It will completely charge the battery of the nook.

And a lot of other things, I'd gather, judging by the number of "tips" it comes with.
Do you have any idea if it will charge an NC more than once?
Since all batteries have a consumable capacity of about 1-2 years, are there any battery replacements available?
Or does this watch really cost about $150 to wear per year?
It's relatively easy to replace the battery:
https://www.youtube.com/watch?v=5WzGC0786U0
The battery has part number of: LSSP482230AB
ok... BUT......... where to buy the specific battery?
i cannot find one. and i think that after 6... 12 months all gear will be UNFINDABLE and the battery ......will be very hard if not impossible to find.
so, all buyers after max 2 years should change the gear

Has anyone gotten any 3.7V batteries to work? There are some cheap ones for RC helicopters that are about 5 for $10. I saw there was another thread about higher capacity replacement. I'm not sure, but the last post mentions having batteries of the same voltage, so I guess that means the 3.7V batteries don't work? I can't find any inexpensive 3.8V batteries that are small enough to fit the gear.
Well, could it be possible to increase the memory too?

The only battery I've found for the Gear is the same one from the UK linked above (here it is on the US eBay site). Including shipping, it's $40. Plus you need the right tools -- I only have a set of miniature philips head and flat head screwdrivers, and taking the Gear apart requires some kind of mini torque bit. (FYI, the flat head screws on the front of the Gear are just for show!) The set the guy in this tear down vid suggests is $30 on Amazon and $20 at Walmart.
So minimum $60 to replace the battery. Concrete examples of cheaper alternatives are welcome. My battery worked fine until a month or so ago, when I noticed it was draining at an extremely high rate -- 8% to 10% an hour. I've done everything I can think of software wise -- different versions of Gear Manager, deleting SAproviders from my phone, and finally finding out there was still a drain when the Gear wasn't even connected, then rooting and deleting some apps, flashing the TizenMod ROM, upgrading to newer FW not yet available for the US, all with no joy.
I can only guess that it's the battery now, but I'd prefer not to spend $60 on a guess.
FYI, I received the battery from the UK and the repair kit from Walmart for the aforesaid 60 bucks, and it was indeed relatively easy to change out the battery. Not like swapping out the battery on the Note 4, of course, but it's less than a five minute job.
So I was able to find a much cheaper option. I found a $2.35 (us dollars) 3.7V battery that works. It's smaller capacity (240mAh), but seems to last reasonably long (went from 100% to 63% in a 24 hour period). I had to cut the connector from the original battery and solder it onto the top of the replacement battery. You can pull the existing connector away from the battery and cut as close to the battery as possible to leave enough of the metal to solder to the replacement battery. I posted a picture on i.imgur.com/fUZD6Re.png (can't post pictures yet) You'll also have to desolder red and black wires on the new battery before soldering on the old connector. Make sure you keep the polarity the right way around when you solder the connector to the new battery. (red wire is typically + and black is -). Here's what the new battery looks like (from the back) once the soldering is done and the connector is pushed back into place i.imgur.com/2jHv7ly.png
I kept a close eye on the watch the first time I charged it and the battery didn't get too hot to the touch. It's been a few days now and it's gone through a couple of charge cycles and seems OK. I don't have enough cred on this forum to post a link to the battery I bought, but if you do a google search for the following, it's one of the first links that comes up:

Great post. Ordered the battery you mentioned as well; it's actually hard to find anything decent above 240mah it seems. I've had my galaxy gear (gear1) now for over 18 months, use it every day and have probably run through more than 300 charge cycles... The battery is definitely not holding the same charge as it did; can't get a full day of use anymore.

Sorry, haven't been checking these forums regularly. Yes, the replacement battery is still holding up well and hasn't degraded noticeably. If you're comfortable with a soldering iron, then go for it.
So I also took the plunge and ordered a 340mah from eBay for about 9€. I cut the pads from the original battery and soldered the leads of the new one on it. It was a tight fit but so far the experiment worked. I am just testing the battery, just sitting on idle and on day two the battery is at 55%. When I am sure it won't short or blow up on my hand, I 'll connect it to the smartphone and see how it goes.

Thanks for info. Decided to take it off the motorola charger for the first night and use a regular Samsung cable. Will power off tomorrow and restart to charge afterwards and see if that fixes the problem. It's not scorching jot but feels very warm to me.

This is normal behavior. The turbo charger produces a substantial amount of heat especially when the battery is low. If you give it time to charge you will find the heat tapers off as the battery fills.

The Moto Turbo charger (Quick Charge 2.0), at full throttle, pushes 14.4W of power into your little battery, whereas a conventional 2A charger (Quick Charge 1.0), pushes only 10W. With great power, comes great heat. (...or something like that. I heard it in Spiderman.) Seriously, excess heat will be generated, but that was all taken into account by the designers, and is perfectly normal. That's exactly why the QC 2.0 chargers ramp down the power as the battery gets full -- It's filling it as fast as it can when the battery is almost empty, just in case you REALLY need it right away, but as it gets closer to full, it's less likely to be an emergency, so there's no compelling reason to keep generating all that heat while it finishes up the charge.
Thanks everyone for responding. Now I understand and wanted to make sure there was nothing defective with phone or charger.

First, I’d like to thank MPJ for sending this 6000mAh battery for testing and this is an unbiased review. I usually don’t like to test batteries because I always carry my extra original battery and QC 2.0 Power bank with me. I have my G4 on May 28th 2015. One week before the G4 was selling in USA. The G4 was given to by LG USA Mobile for the G4 Trial Program. After a couple of weeks I have brought a battery on Ebay for about $7 shipped from China. This is the first battery I can find but its a fake battery that wouldn’t hold charge and drain like crazy.
This MJP battery will give a MASSIVE boost to your phone's life. Makes the phone a lot more beefy and a bit more heavy, but if you are a heavy user it is way more than worth it to try. The case/battery is flatter than the standard back of the G4 which makes it sit steady on table tops which I liked.
The charging speed is about the same as the original battery but 2 X more because its 6000mAh. The charging temperature is around 23 degree C which is quite cool. I had even tested to see the battery will hold charges.I fully charged the battery and left it unused for 3 days. Then put it on G4 and its still at 100%.
Pros:
- Ridiculous battery life boost, like an insane jump over standard G4.
- New case is steady on tables and will not scratches the camera lens.
Cons:
- Bulkier/beefier phone, heavy users like myself will find this way outweighed by the battery life gains.
- No NFC and wireless charging.

Nice review but pretty ugly case.

First, I’d like to thank MPJ for sending this 6000mAh battery for testing and this is an unbiased review. I usually don’t like to test batteries because I always carry my extra original battery and QC 2.0 Power bank with me. I have my G4 on May 28th 2015. One week before the G4 was selling in USA. The G4 was given to by LG USA Mobile for the G4 Trial Program. After a couple of weeks I have brought a battery on Ebay for about $7 shipped from China. This is the first battery I can find but its a fake battery that wouldn’t hold charge and drain like crazy.
This MJP battery will give a MASSIVE boost to your phone's life. Makes the phone a lot more beefy and a bit more heavy, but if you are a heavy user it is way more than worth it to try. The case/battery is flatter than the standard back of the G4 which makes it sit steady on table tops which I liked.
The charging speed is about the same as the original battery but 2 X more because its 6000mAh. The charging temperature is around 23 degree C which is quite cool. I had even tested to see the battery will hold charges.I fully charged the battery and left it unused for 3 days. Then put it on G4 and its still at 100%.
Pros:
- Ridiculous battery life boost, like an insane jump over standard G4.
- New case is steady on tables and will not scratches the camera lens.
Cons:
- Bulkier/beefier phone, heavy users like myself will find this way outweighed by the battery life gains.
- No NFC and wireless charging.

Somehow we always end up testing the same products.
I have one of these also and am currently on day 2 of the first charge.
I will have a review to post up here in about 2 more days with my opinions of this product.
So far it is looking good for me.
oh boy how ugly ...
is there any 4000mAh or 4500mAh battery ???
because 6000 or 8500 are good in term of battery life but are making the phone look really UGLY

+1 this!
This is why I just bought some Quick Charge chargers... with all my other phones I ALWAYS ended up getting an extended battery, but with the quick charge on this phone, I'm fine! Got 2 quick charging chargers at home, and one in the car. Just throw it on when I'm not using it. This phone charges SO FAST on these chargers that I don't even plug it in at night because it will be on the charger for 7+ hours longer than it should be.

Completely agreed. Anyone with even a modicum of a fashion sense will absolutely stay right the hell away from this.
But hey, it's called a "Business battery" for a reason!
Just keep that sh*t hidden in meetings and you're good to go
MPJ was kind enough to allow me to test out their new 6000mAh Li-ion High Capacity Extended Battery For LG G4.
I have had this battery for about a week now and have been using it every day.
I consistently am able to get two days of use out of it with everything syncing normally and brightness set at 75%.
I went three days one time and had to charge it when I got home from work, so I would say the max I was able to get from this battery was two and a half days.
Charging time for me was about double the time it takes to charge the standard battery, which makes sense as it is double the capacity.
I did however find that my Quickcharge 2.0 charger did seem to charge it slightly faster, but this battery does not claim to be Quickcharge compatible so it may just be that my Quickcharge charger is just a better charger.
I had no issues with heat while charging this battery. It actually seemed to be cooler while charging than the stock battery.
I did find that in my daily use of this battery and case I found it much more enjoyable to use the phone while on a flat surface due to the flatter back of the case.
It removed the normal rocking this phone comes with when set on it's back.
The extended portion also prevents the camera lens from touching any surface when setting the phone down, preventing scratches.
There is some added bulk to this case and that was to be expected as it is double capacity from the standard 3000mAh stock battery.
I however did not notice it in hand much at all due to the well rounded edges of the back cover.
It actually fits rather nicely in hand and was comfortable to use.
The ports on the back cover all line up perfectly. The opening for the volume and power buttons fit so perfect that you would think LG them-self designed this back.
The opening for the speaker is sectioned off so you get better sound coming directly from the speaker through the opening with no distortion from going through the rest of the case.
This is one little thing that sets this case above the others like it.
The only problems I can find with this case is the lack of NFC and the smooth texture of the back they sent me.
They do however sell a textured back cover for this battery for $9.99.
Finally the price of this is perfect at $29.99 with free Prime shipping on amazon.

Pros:
Double capacity battery = double usage!
Comfortable back in hand
No rocking of the device when on it's back
Good charging time
Well made case
Price
Cons:
No NFC (seriously, this could be a deal breaker if you need it, there is no way to add it without some serious modifications)
If you can live without NFC (I can) and you need either more charge in your phone for day-to-day use or just want to make your phone last for more than one day on a charge, I would recommend you purchase this extended battery and back plate.
I would give this 5/5 stars
I will include some pictures so you can see for yourself what this battery is like.
Sorry about the lower quality pictures, I had to use a backup phone to take pictures as my G4 was in them
I will try to answer any questions you may have about this item.
I received this at a discount in exchange for an honest review, this does not change my opinion of the battery in any way.
If this review has helped you at all, please click thanks below to let me know.

Where can I order a more textured back door for the extended battery? The back door in the pictures looks do glossy and flimsy. Someone mentioned one may be available for $9.99?

Same link as the battery http://www.amazon.com/Extended-Batt...821189&sr=8-7&keywords=lg+g4+extended+battery
Just click the back you want from the options.
Im getting 5+ hours screen on time from the stock battery, so 5 hours with 40% left means this is closer to a 4500mah battery labeled at 6000mah. Dirty. Can you confirm your screen on time barely reached 7.5 hours screen on time, and not 10hours?
A 50% boost is not worth making my phone 700% uglier

Each person's screen on time will vary.
You can not compare mine vs yours. (or anyone else)
One person may have an extreme battery saving setup that gives 12 hours screen on time from stock.
While another person could be running always 100% brightness with tons of background apps running always and using tons of battery and only get 2 hours screen on time.
As for your claim about capacity, you should not assume things with no proof.
I have the battery and did a review on it.
It is definitely 6000mAh.
I have a USB voltage detector and it shows you current charge rate and total charge.
It showed me between 5800mAh and 6100mAh every time I charged mine.
Here is a picture of the one that I have so you know what I am talking about.
Nice Review
you review is really nice. But are you sure that this extended battery will to disturb the terminal of board? I am sorry I am little bit confused.

Yes, I am also a bit curious about that.
Looks great ! But to much big .. Will be really great to see a 4000mah or 4500mah with cover a little bit bigger but not like this one
Just bought my G4 there is 3 days and for the moment really good ! :fingers-crossed:

Easy killer. I clearly asked "if" that's what they do - and yes i used my own screen on time of 5 hours as estimate, but only because the last 3 in a row non-MPJ ebay batteries purchased ended up being totally bogus. Literally half capacity.
As it turns out - YOU WERE RIGHT, i bought a pair of 3000mah MPJ replacments for the stock battery, and while the battery discharge graph is very strange and shows charging-sloped-inclines during sleep (5%-10% spikes of battery remaining) you absolutely do get every advertised mah. They last as long as the stock battery.
Thanks for the recommendation
I will just stick to quick charge and 2 batteries. I spend a lot of time on the slopes so I would rather swap batteries then have bulk in my pocket
But by this way you are adding a lot of pressure on your phone charging Circuit and maybe your are shorting its age!

What pressure are you talking about?
As long as no current and voltage limits are exceeded, no problem .

I'm talking about the longer charging time.. 2 times more
