Battery issue - Samsung Galaxy W I8150

Dunno how to say it in English but physically my battery is getting bigger, and when on battery low, it gives me the notification and the phone just turns of on the same second.
The battery is starting to be like a balloon and and hardly fits in the phone, can anyone tell me what's happening?
btw, I'm using the stock ROM now.

Your battery is bloated. Congratulations. To fix this, there is only one solution. Change your battery.

Thanks for the reply, but does anyone knows why did this happen? My device is 1 year old last week, it shouldn't happen that fast I guess.

there are many reasons why your battery is bloated .......... one of charging too much time away from his proper time, time you charge the phone you are using (playing games) .....
sorry with my english

Correct

I use it a lot while charging specially for games, and lots if times I had to charge it while it's still have more than 40%. OK lesson learned and the new battery will be treated differently. Thanks.

Hi, found this on eHow and as automobile electrician dealing sometimes also with batteries i cannot confirm that your battery was bloated just because of playing games an charge phone at same time. Li-Ion cells don't like to be fully discharged. When u charge them before they go out of power is the best you can do to preserve their capacity.
Don't use your phone with silicon case when gaming because it can prevent air ventilation in the phone and cause it to heat up more when placed under heavy load like when playing games.
And now what can contibute to a battery bloatup:
Battery Components
• Most cell phone batteries contain a lithium-ion mixture. Lithium is an alkaline metal, and its ion simply has more electrons than protons. The battery also contains a positive and negative electrode, and when you use the battery, the lithium ions move from one to the other, creating an electric charge. Under normal circumstances, the lithium ions can continue to absorb and dissipate energy. However, if you expose the battery to certain conditions, its chemistry can change, causing undesirable effects.
Water Damage
• Your cell phone battery is extremely sensitive to water. The plastic casing provides some protection; however, if you expose the metal electrodes to water, they can corrode and become ineffective. Water leaking into the batteries case can cause it to appear bloated. Discard such a battery immediately because the lithium solvent can be harmful if you come into contact with it. If the phone has been submerged in water, this is usually enough to cause water damage to the battery if there is not a tight seal between the battery and the phone.
Heat Damage
• The lithium solvent that carries the charge from electrode to electrode is extremely sensitive to heat. If you expose the phone to temperatures that considerably exceed 77 degrees Fahrenheit, the battery may lose its ability to hold a charge over time. This is considered normal. However, if you consistently expose it to higher temperatures, then you can cause the lithium-ion mixture to rupture the cell, which can cause the battery to appear bloated. Most lithium-ion batteries contain fail-safes that prevent them from operating in extreme temperatures, but there is no guarantee that these will work in every case.
Prevention
• Prevent damage of this sort from occurring by not exposing your phone to extreme temperatures and unsafe environments. For example, do not bring your mobile phone near pools or inside of saunas. On hot summer days, keep the phone and other electronics out of direct sunlight.

But I can confirm this. I´m having actually here 4 batteries for the SGW and one of them is bloated due to heavy usage while charging the battery. This battery was my best battery but now it´s just a paperweight. It´s still working well though it´s bloated, but I´m not going to risk anything.
You can´t simply compare a car with its lead battery to this device, because in the car the battery is just needed to start the car. Once the engine is running the battery is not needed as the generator is producing enough electricity for the entire car and to charge the not needed battery.
You can even remove the lead battery completely and just connect the car to a powerfull enough source to get it started. Onec its running, you can remove the source too and it will continue to run.
With the SGW and its LI-Ion battery things are a bit different. You for example can´t simply plug in the charger and turn the device on without the battery. The battery is still neeeded to power on the device for two reasons. First is the charger might be not strong enough to offer enough power but the obvious one is, the circuit inside the phone reduces the charging current to a max. level and the voltage to be 4.2V max. It acts like a constant current and constant voltage source where the preset max limits can´t be exeeded. The real charging current and voltage are depending to the charging level and the battery resistance, but will never exeed the max limits in a proper working circuit.
Additionally this circuit is feeding the battery directly, so the current is floating first into the battery and then the battery is feeding the entire device. So at heavy usage the power offered by the circuit will be not enough to be simply passed to the device and so the battery will be stressed twice, as it´s charging and discharging at the same time.
This is still a simplyfied explanation to what is really going on, but explains a little bit why you can´t compare a car with it´s battery to this device.
Also, the batteries for the SGW do not offer it´s own protection circuit. The only circuit that protects the battery is build in into the phone.
So the best advice that can be given here is to avoid heavy usage while the battery is being charged. Better charge it first, use it then and recharge when not in use.

I´m not sure where you digged this out, but this is simply not the full truth. In neutral stage each element is having as much electrons as much protons it has. Ions are either having temporaly more or less electrons. They can be ionized positive or negative.
In a normal Li-Ion battery it´s the anode that consists of lithium and is having positive lithium ions, so less electrons than protons.
In a lead battery both, the anode and the cathode consist of lead. One is positive ionized and the other one negative.

Sorry if it souded as i would compare a Li-Ion to a lead battery. I was actually not doing that. By that i meant that i understand somewhat of batteries. I've learned about batteries (how different types work) back in school. All Li-Ion based batteries have their own protecting circuit. It is not depending on the phone. This circuit built in every Li-Ion based battery prevents it from beeing overcharged, wich would result in the battery exploding. It also gives the phone a limited feedback on battery charge status, and perhaps somewhat potecting the battery to be fully drained wich would result in irreversible damage to the cells. I agree with you that it is better to charge when not using them, but in real life this is not easy to do when you (by what cause ever) want or have to use your device. I am not a gamer so i am not using my phone that way.
Since i am using my phone lots of times plugged on a charger, making phonecalls and doing other stuff like email, surfing the web, watching videos and so on, and never get close to that issue (battery is almost 2 years old) i still don't think that that would be the biggest problem.
On hot days is it not recommended to use our devices with heavy loads, ofcourse you could climb into the fridge (may not be a problem then), and it is also advised to avoid humidity. That's all i know for now, that it would contribute to a bloated battery.
Sorry if i unattendedly caused some confusion.

Not all Li-Ion batteries have their own protection ciurcuit. Only the protected ones. Do a search on google about protected and not protected Li-Ion batteries.
In cellphones most batteries are not protected ones because of the circuit taking to much space and so incrasing the battery size a lot. Therefore the protection circuit gets moved into the phone but the battery itself is not protected at all. In most batteries the feedback you will only get is the temperature. It´s mostly a simple thermistor either being somwhere close to the battery or inside the battery. The rest is calculated by knowing the capacity and monitoring the voltage and current drain.
So the only circuit you will find in not protected batteries is the one for reading the thermistor, if there is one build in. But this circuit will not protect the battery against a short circuit.
Just to not confuse about this. There are of course protected batteries for cellphones as long the circuit can fit into the part where the connections are.
But the truth is this circuit can fail to disconnect the battery from a short circuit and there are even batteries with fake protection. So there is a pcb with a circuit, but this is just fake and doing nothing.
However regarding this discussion about bloated batteries it doesn´t matter the battery has a protection circuit or not. The protection circuit only disconnects the battery if a short circuit occurs or the battery voltage drops below 3V.

Test to retrieve a battery almost dead

Hi all,
my first original htc s620 battery gone, some time ago i buyed chinese battery (now gone). This is ONLY A TEST TO TRY RETRIEVE A CRAZY LI-ON BATTERY
(i mean a battery that not hold a charge).
The lithium polymer batteries suffers high temperatures. Reading around i discover exist a way to TRY in retrieve a Li-on Battery. I'm testing it and soon we will if it work or not.
I do not assume liability for damage caused by this method. This method can be easily found online. Remember that it can be very dangerous to experiment with lithium batteries.
Ok, im testing it so:
1/ Wait until your device turns off (due to ended battery);
2/ put the battery in an airtight container and place it in a freezer for 2 hours (more or less);
3/ remove the battery from the freezer and wait for it to come back naturally itself at room temperature (so keep it away from heat sources) , it can takes about 1 hour
4/ put battery on your device and recharge it for twice the normal time ( more or less 4 hours). Recharge the battery while holding the device OFF
5/ after a long charge, the battery will become usually a little hot . So remove from device , wait until it returns itself to normal temperature and then put it back in the freezer for another 2 hours.
6/ remove again from freezer, wait it back itself at normal temperature (about 1 hour) . Then put it in the device and test how long it works this time
It might recover some charge because seems low temperature (around and not too much under 0°) stabilizes cells.
ALWAYS REMEMBER TO WAIT FOR THE BATTERY RETURNS ITSELF AT NORMAL TEMPERATURE . BE SURE THE BATTERY IS NOT SUFFERING FOR FAST CHANGES IN TEMPERATURE ( IT CAN BE DANGEROUS) .THIS TEST CAN BE DONE ONLY USING A LI-ON BATTERY (ABSOLUTELY NOT ON A NICKEL BATTERY)
I'm testing it . I'm curious to know if this method can be useful.
In the next days i will put the result.
If you look for a method to measure the capacity accurately, look at my signature. Looking forward to read if there is any success (I doubt it).

ok this is the result. I've found some changes.
After freezer treatment, seems all my two battery maintain better ( little more time) their charge segments. But the batteries did not lose the effect of "virtual memory " . This means they continue to not be fully charged, infact the device goes off several times before the it can no longer switched on. BUT as i said before, the segments charging now last longer than before.
So this method lies partially. You absolutely cannot fully recover a worn battery but...surely the ice temperature make some little changes in your battery.
i'm buying a new "extra long" chinese battery of 2200mA
@tobbie : do you think a new battery must be charged immediately ( when it will arrives) or it's better if i use the partial charge i will found on it ( before recharge)?
My experience with Chinese batteries is very bad. You will get a labeled block of bull**** not worth the postage. I have tested several in my efforts to find the best one and they ALL (no exception) perform worse than the original ones. They never keep the promise they make on the capacity.
If ever possible go for the original batteries, next best is quality replacement parts (whatever that is...) or try your luck with cheap Chinese ones if you don't care about the few bucks.
Good thing is that you have a reference method for comparison, so I would be glad to get your battery rundown to judge upon it.
Li-Ion batteries have no training phase and also no wear depending on charge cycles (unless deep discharged). Look up my thread on battery capacity measurement, some interesting links there.

Repair battery.
I have the original batteries in both my S620's, try this, when the phone starts switching off after a shorter period, ie less than a day, when it switches off switch the phone back on until it again switches off, repeat this until it won't switch on. Recharge and repeat the process, you should find the battery works like new, mine did.

...another miracle in batteries life
I only trust measured proof. Can you supply this, e.g. a tracked run-down like suggested in the measurement thread in my signature?
There are rumors (no proof) that devices "learn" about the battery and they can be reset in learning by doing as you suggested. I have not seen anything like this happen in the devices that I own. Charging when device is switched off is done by HW only (the chip) and the shutdown is purely guided by measured voltage. No space or logic for any sophisticated memory...
I don't care if you believe me, I only wanted to help, if you don't believe it - tough. All my phones work with original batteries, believe it or not.
I don't argue that original batteries work (they do best for me as well). My doubt is about the procedure to "train" the device to recognize batteries better and consequently deliver a better duty cycle after that.
My experiences are different. A "dead" battery stays as "dead" no matter what you do to it:
deep discharge (as much as possible) + recharge: no change
freezer treatment: no change
Everyone may try himself - no harm expected. My proposal just is to put the "improvement feeling" on a metric base, so just to measure it.
The problem with subjective observation is that your normal use patterns are so much depending on the environment (location, movement, device use) that they are never so identical that you can compare one week of use with another.

HTC battery trick for HD7 and possible others

while on charger when the battery is reaching 97% , turn on/off/ the phone
multiple times , each time taking a 2 mins break u will notice the charging takes longer and the percentage is always stuck at 97% - 99%...
another form of bump charging for wp7..basically the phone will take longer to cut off charging at 100%
post yr results here if u saw improved battery life
you will find this quickly damages the long term battery life of your battery
Well that isn't so bad as batteries aren't expensive anymore. Just 12€ or so.
this would probably work for any phone not just HTC but you are basically tricking the phone into over charging the battery which weakens the lifespan of the battery, all for a few extra minutes of battery life, not worth it.
Yea, this is terrible, destructive, downright negligent advice.
Yes, not good. I work with battery chargers and Li battery characteristics and you will actually age and get less capability very shorty doing this so you won't get those extra charge lengths for long (you do this maybe 20 times and you will in worse shape after that than someone just doing normal charge).

Hah, this coming from the guy that advocated doing that.
u understand yr cause of concern....this will not wear out the battery faster...unless batteries that u use do not have rapid discharge capabilities eg. Iphone poly battery.
In this case it will wear out the battery faster
basically the battery wears out the same rate as all other batteries...
the cells degradation occurs each time u charge...
and modern batteries do not overcharge...some like HTC batteries will discharge rapidly to 80%
basically u are just charging the remainder of the cells
Quote me where I advocated doing that.
Please do a post search on me and you'll see that we've had this discussion in the Vibrant forums already, where I stated it was dangrous.
What I do advocate is keeping your phone on a charger whenever possible (bump charging).
I do not advocate tricking the phone into overcharging. No one wants a battery to blow up in their face, you know...
Or maybe you're confusing a confirmation of that working with an advocation that it's okay to do it? In that case, your school district obviously failed. It has nothing to do with what I stated on these forums or otherwise.

The issue doesn't come from fear of wearing the battery down. It comes from fear of a device blowing up or catching fire on someone who is overcharging it. There is enough evidence even on youtube of batteries going haywire. This is a risky tactic to achieve basically no noticeable increase in battery life.
The HD7 in a high 3G coverage are (full bars, 3+ Mbps download speeds) gets ~4 hours of battery life under heavy use (mostly browsing, reading Pulse Reader Articles, and checking Social Networks now and then - no Music or video - so really it's only heavy in the fact that the phone didn't sleep a lot, should be called more moderate if anything... Phone shows 67% battery left with 2 hours projected uptime). Overcharging your battery won't change that terrible battery life into good battery life. It'll only make it 5 minutes less terrible.

they can only blow up by removing their circuit protection
If you say so
Batteries still overheat, catch fire, and in rare cases blow up. Overcharging them is risky. Yes, it's rare, but would you want to be that 1 in 10,000 case where it does do that, in your pocket or something?

1.) This will wear out battery faster, why? You are fooling the sensor to charge the battery more.
2.) You can overcharge batteries, don´t know where you found out you can´t. The only good thing is, that the modern phones cut out charing when battery is full and is running on charger (to keed battery charged).
3.) My battery is not rapidly discharged to 80%, I charge it up 100%, and it stays there, when your battery quickly discharges to 80%, that´s your problem from experimenting with charging.
Again - STOP TELLING PEOPLE TO KILL THEIR BATTERIES, I told you numerous times, you always act like you invented something, you didn´t, modern batteries use more advanced techniques to help them prevent from being damaged, overcharged, deeply discharged, etc. So stop telling people how to fool these sensor and stress the battery.
Thank you
Hey guys,
I wouldn't recommend this advice as well.
As for me, I bought a second battery 1600mAh.
I use this battery as my primary battery, now I get 30-40% more time on my HTC HD7, and actually can go a whole day with 2G only. While before the phone dies before the end of the day.
While my original battery I keep fully charged sleeping in my wallet, so if the 1600mAh is fully depleted and I'm away from a charging station, I quickly replace and resume working on my phone. This method gets me through a whole day of work+games+social.
I don't remember the price of the 1600 battery but it costed me 10-15 Euros I think.
I believe this is most practical than carrying an attached battery to your phone which results in a gigantic phone in your hands. Or overcharging the OEM battery and probability of having it blow up.
What do you think guys?

Is it ok to leave device connected to computer at 100% battery?

Hi is it OK to leave our device connected to the computer at 100% battery level? I develop android apps and there are times I need to debug and have my device connected for hours for debugging. At 100% level, I noticed the device is not heating up and I assume this wouldn't damage the li-ion battery or would it?
Does this device have an ic chip to handle overcharging ?

It's not good for the battery. Lithium batteries don't like to be fully charged all the time.
I don't know about chips, but it must have overcharge protection, otherwise the battery would go up in flames.

At 100% level, I noticed the device is not heating up and I assume this wouldn't damage the li-ion battery or would it?
Does this device have an ic chip to handle overcharging ?

Lithium batteries does have overcharge protection.

I've had no issues doing it with a few devices and my battery has never had issues, I always plug my devices in and let them charge overnight whether they need it or not

From what I have read, there isn't a need for concern. The device automatically cuts off charging at 99-100% and there is overcharge protection. Unless I am missing something.

I've noticed that (at least when it's close to being full) that the kernel watches it like a hawk. It seems to be checking on things every 20 seconds according to the dmesg output. It's reporting the voltage, temp and calculated charge level each time around.

I am really curious if it does really have because I have an li-ion battery on my Samsung galaxy ace and I have been doing the same thing. But now the battery performance is a lot lower compared to when I first had it. What seems to be the reason? Is it true for all lo-ion batteries?

Has been said before, but here we go again: Things that are BAD for your LiIon/LiPoly battery:
-storing your battery at full charge (which is essentially what you are doing)
-running down the battery to "0%", i.e. < 3.40 V repeatedly
-heat
-very fast discharges (not possible with a smartphone)
-very fast charges (again not possible)
So, if you want to get the best life out of your battery, it is definitely NOT advisable to leave it connected to the charger at all times. It will (or should) not get overcharged, but simply being at full charge for a prolonged time damages the cell more than being used in a normal fashion.
And yes, all LiIon batteries in phones have overcharge protection, because LiIon batteries burst into flames at just about 4.55 V (which is obviously very close to the full charge voltage) and companies want to avoid that in general.
I'm just going to leave this here.
The HTC one has a hardware circuit, as well as software on a PMIC (Power Management Integrated Circuit -- a tiny chip that acts as a micro processor) that shunts current away from the mainboard and battery once the battery has been fully charged. You could leave it charging for weeks at a time and have little to no effect on the battery or the device.
Most consumer electronic devices have the same protection, and have for years.

That is a very clear explanation. Is it possible to disable charging when connected to computer (programatically)?
It is really a pain to disconnect it every time I hook it up on a computer for debugging and it wouldn't even guarantee to discharge when I hook it up and disconnect when not debugging since I do it frequently. When debugging, everytime I change and compile code I need to hook it up to the computer. I am debugging games and sometimes smali files so an emulator is not really an option.

I guess it would be possible by modifying the Android kernel.
The best practical advice is probably: Buy only smartphones with exchangeable batteries. :cyclops:

Facepalm.gif.
Op said he connects his machine for HOURS. If he said YEARS I'd agree with you, all li-ion modern batteries have circuits which moderate their charge cycle to condition the battery when plugged in. When your device is plugged in it doesn't actually mean the battery is charging if it doesn't need it then it won't be. You might want to research that.

Of course its not charging if its full, otherwise it would go up in flames. But Valynor is right, storing lithium batteries fully charged is not good for the battery.

Which is awesome, but that was not what the OP was asking. All Li-ion batteries have overcharge/discharge protection which means the OP can do as he has asked without worrying.

[Q] Battery Conditioning?

What's the best method? Drain to 0, charge to 100 a couple of times? Or charge to 100, turn off, charge to 100, and repeat? I've read some crazy stuff all over xda.
Edit:
Read some more stuff. Bump-charging and constant re-charging (preferred over single deep-charging) were mentioned as good for Lithium ion batteries, which I assumed we had. (Can someone confirm?)
Still would like your opinions!
Bump charging is in fact not good for the battery. It will stress the battery. Also no conditioning is needed with lithium cells. So just use and recharge like normal. There is no break in period. Also I know alot of people swear by deleting battery stats. This is not needed nor does it even do anything. All it does is wipe a log file. The file isnt used for anything other than telling you what has been using battery when you go to your setting and click battery. Google has even confirmed this. I will say this though. A few months to a year from now, if you still have this phone. If you notice severely decreased battery life. Take out your battery. Put it on a flat surface and spin it. If it spins the battery is bloating and should be replaced.

Avoid heat
Heat is the enemy of your battery.
In addition to what patrao_n recommends, I'd add removing the phone from any case you have it in before charging it overnight.
I love my cheap $5 TPU case, but it does act as an insulator and make the phone retain heat from charging and heavy use, especially when using 4G in a low signal area.
Yeah, I've noticed that it drains faster when I leave it on a table out in the sun as opposed to my pocket. No case for me.
So no conditioning needed at all? That's cool. Thanks guys
Well you have to be more specific regarding batteries. Whether it's the OEM battery or an extended battery like QCell. For the stock battery you don't really need to do anything besides the initial 8 hour undisturbed charge. QCell has it's own specific instructions that really don't go with the rules of lithium batteries but it works. Although for all batteries it's recommended to not let it fall under 20% cause killing a battery completely is really bad for it's longevity. So pretty much you don't need to condition anything unless you buy an extended battery and in that case follow the manufacturer's instructions to the letter.

That's far from accurate. There are phones with 6000 even 18,000 mah capacities. For example the Samsung Galaxy M31 has 6000 mah.
Mah numbers stated on batteries are just that, numbers. There are phones with even lower battery capacities that outlast higher battery capacity phones by several hours including the 20x as yt video showdowns between different phones demonstrate. No doubt, although a higher mah indicates greater battery life generally, relatively speaking, battery life overall depends more on what's determined by the interaction among software, voltage and hardware than what's stated on the battery.
It's not just a drop in mAh's that warrant replacement. If there's any detected battery swelling the battery needs replaced asap.
The risk of a thermal runaway event increases dramatically with a damaged (swollen) Li battery.
This can happen even with a new battery.
The swelling can possibly damage the phone as well, without going supernova, by putting pressure on surrounding components... like the display.

Your dropped battery capacity isn't surprising but natural during the course of its use. My own battery has a capacity of just shy of 4700, somewhere in the neighborhood of 4630 last time I checked.
As you stated, your battery was at one point at a full 5000 mah and lost 10% of its capacity to what's presently 4500. But just so you know, your battery is not precisely filled to 5000 mah right out the factory. In reality its always less than whats stated; the reason being is that batteries differ in capacity during manufacturing mostly to cut costs. Battery manufacturers round the numbers to the nearest hundredth or thousandth to read batteries easier. Hope this helps.

Correct. This is why within the battery, cells are damaged which skip proper readings by the amount equal to the amount of juice generated by the lost, damaged cell.

This is what a typical Li polymer battery used in cell phones looks like.
There's no hard case to contain it so any internal pressure immediately becomes an issue.
Swelling in the cell it's self will distort the structure of the cell and alter it permanently.
A sealed plastic bag surrounds it to hold any vented gases or goo.
It's just one cell and it's rolled construction is similar to a capacitor.
It's alarmingly flimsy... and packed with energy.

Sorry man you not right
No there is no any smartphone with 6000mAh Batteey you too naive to believe lies and fake statements from china That is complete crap what you saying that lower capacity batt will outperform battery with larger capacity.. Where do you live boy?
I will explain you about the batteries ok?
As I know about batteries. Li-ion batteries has best density
Speaking of cell density batteries there would have to be new design and new technology.
For more battery cells you obviously need larger battery ! THAT'S WHY Mate 20 X / Honor Note 10 battery is the largest from all.
Battery Size
Although higher-capacity batteries generally last longer than lower-capacity ones, they are not always suitable for use in every device. To achieve a higher capacity, battery makers often have to fit more cells into each battery. Cells are the parts of a battery in which the chemical reaction needed to generate electricity happens. Increasing a battery's cell count can in turn increase both the size and weight of the battery, making it unsuitable for use in slimline devices such as smaller cell phones and netbooks. The temperature and speed of electrical current discharge affects the overall capacity of the battery. Poorly made batteries often heat up too quickly resulting in performance issues or degraded capacity.
To calculate a battery's life, divide the capacity of the battery by the current required by the object it powers. For example, imagine that you have two batteries for your cell phone, one with a capacity of 1000 mAh and one with a capacity of 2000 mAh, and that your phone requires a current of 200 mA to function. The first battery would power the phone for five hours, as 1000 divided by 200 equals five. But the second battery would power the phone for ten hours, as it has double the capacity of the first. While a larger number indicates battery power, larger mAh batteries may not be better if it is a poor quality battery. It simply means it can store more power.
Cell phone battery life is heavily dependent on the way in which you use the phone. The more features you run at the same time on your phone, the more current your phone requires and the quicker the battery's capacity drains. This is why using WiFi or running complex games on your phone drains the battery quickly. As such, a battery with a high capacity that is used to power a smartphone might last for less time than a low-capacity battery that powers a basic device.

You're right about the waterproofing, don't test it.
It might work...
In my case it wasn't abused and I was lucky it didn't take out my Note 10+'s display.
Heat and/or rapid discharging can cause it.
Or a bad copy from the factory.
Or simply accumulative damage over time and insults. I live in the desert so heat is omnipresent. I try to keep it cool especially when charging.
My phone has never been cold charged or even close to damp. Cold charging (>40°F) can trigger a run away thermal event or cause permanent damage.
Charging in temperatures under 72°F can cause Li plating which permanently degrades the cell.

Youre not bright when it comes to the subject of battery and 1000% wrong yet again. The Samsung Galaxy M31 is korean which you mistakingly think is chinese and has a 6000 mah battery which I'm sure youre too afraid to verify in google. The Helio P70 has a 18000 mah battery which of course you deny since you dont operate in our reality.
Longer capacity batteries dont guarantee a longer lasting life than lower capacity ones. Case in point, the iphone xr with 2940 mah equals the note 9 with 4000 mah as this yt video proves:
Youre trying hard to be relevant by trying to edge out people's comments with your nonsense. Being negative and insulting others violate forum rules which doesnt win you friends here. I reported you to the mods btw. Guys like you dont last long here. Be educated before you look foolish again.

As you see they are somewhat fragile. I inadvertently ripped right into the active layer before I knew it after I removed the outer bag
Crazy. A fruity smelling solvent was also present. I wiped down my hands even though I sensed nothing; caustic burns are the worst.
It's a good idea to have little charge on these when >gently< removing them.
I'm not as comfortable with these packs as I was before, ignorance is bliss... until it starts smoking.
