Hi Escalhavardo,

I'd have to disagree with some of the previous comments generalizing batteries. In the battery world most suppliers have protected chemistries , with each Chemistry having strengths and weaknesses relevant to the duty cycle the cell will see.(not trying to lecture just stating a fact)

When trying to isolate a single issue like fully charge and discharge or not...It's also important to keep in mind battery "performance" is very much related to the cell's history sooooo full cycle at low rate (maybe dim screen, running background apps while checking facebook occasionally, with a low RAM launcher on an old droid ERIS etc... vs a year of back to back Angry Birds marathons with the screen brightness cranked up running a poorly optimized ROM and on a superfast newer Samsung model, are two scenarios that I promise will have a much more significant effect on most mature prismatic Li-Ion mass produced cells then general depth of charge.

Now to answer the question you asked directly... unfortunately i don't have data that says you'll see significantly longer life by only charging to something like 80% and i don't have data that supports sticking it in the fridge helps either (not to say either isn't true, i just don't have test data personally and googling something like that will just get you other peoples opinions) there are tons of physical and chemical phenomena at play and still too difficult to say without getting into specifics.

Hopefully some higher level battery folks will weigh in too, there are a lot of myths out there:eek:

For those who wondered why charge till only 80% can have a look at this thread and you'll understand more clearly. I personally only charge my devices from 20 to 80 max too. :) It's a good tip.. Enjoy your 2000 cycles..

Edit: If you find 20-80 is too short, go for 15-90..

Thanks for the information! I am very tired of these batteries...
[General Accessories] icstm:
I do not think that link answers anything it is a discussion with no conclusion and what ppl seem to get confused by is the current rating on chargers, this is not "pushed" by the charger, it is the maximum that can be supplied by the connected device "pulling".

The voltage is set by the charger so is important and the quality of the transformer converting your AC wall supply to the low voltage DC is also important.

That is why I am not clear on Xenova's advice in the text I quoted from about only using the supplied charger. Using a Sony or Blackberry charger on a Samsung phone should cause no problems.

The other advice on how to charge is all very useful though.

Lithium

Hi guys,

Is lithium Ion Battery when overcharge easily burst? What's the life span?
[General Accessories] Hermosa:
Great tips. I bought my phone 1 years ago, but the battery stays good.

---------- Post added at 07:01 AM ---------- Previous post was at 06:58 AM ----------

It had better not be overcharged as this could affect the life-span.

Life Span is that how many times the battery can be charged.

:D

[General Accessories] Roy360:
oh no!

I just bought a replacement battery for my phone from Aliexpress. My phone is pretty old, so this replacement battery was probably manufactured years ago.

I did get a large capacity battery, 2500mAh vs 1600, but still disapointing to know that a good chuck of the 2500mAh might be lost.

(Will have to find an app to keep my screen on to compare before and after times now.)

Is there a way to see how much capacity a Li-on battery has lost? CPU-Z still shows my battery health as 'Good'. (I'm assuming that's as detailed as it gets. )
[General Accessories] dizzyman44:
Thanks for the useful info. Constantly recharging a lithium ion battery does not shorten the battery life. I get used to charging my cellphone everytime it goes down to 70%. Is it OK or not?

How long should a 18Volt Battery last from fully charged to weak if used this way

How long should a lithium bat5tery last in a drill i8n one use from full to weak?
[General Accessories] PhoneAddict98:
Now this thread is VERY USEFULL, it deserves to remain alive.

And as i understood after reading everything from page 1, the optimum percentage to charge a Li-poly(or Li-ion) battery is at 20%(or 40% as stated in an article other than in the quote below) and charge it till it reaches 80%. Correct me if i am wrong.

I bought a new Android phone recently that does not have a removable battery and I usually charge it from 5% - 10% till it reaches 100% once each day. And it seems that was the wrong way, glad i came across this thread before it was too late while searching online, it made so many things clear, thanks again.

I need some advice!

I recently bought a new OEM battery for my GS3 and the manufacturing date on it is 2015 04 21. Now I paid a premium for it at a authorized reseller (legit shop) but seeing it was made approx. 15 months ago from today,should I keep it or return it? Does Samsung even still make new batteries for the GS3 in today's age or am I better of just keeping my brand new sealed battery that's 15 months old already? Thanks!

Hello everyone, seeking some advise on batteries in tablets.

I am operating a small business that uses android tablets. These tablets are required to be plugged in all the time and screen on continuously for approximately 9 1/2 hours every day.

Is there any risk of battery fire or explosions when using the tablets in this way?

Any danger to the voltage staying at 4.2V continually while the tablet is in use?
[General Accessories] James Weinreich:
After the whole "Note 7 catching fire" issue, it really got me thinking about Lithium batteries and their volatility.

What's the general consensus on how hot a Lithium battery can get before it poses a threat to fires and explosions? I'm thinking along the lines of what risks and dangers could happen to a phone's Lithium battery, if it's left inside a really hot car on a sunny day (say 43 degrees Celsius or 110 degrees Fahrenheit)?
[General Accessories] rohnallen:
If you keep plugged your tab in all the time. Battery life will reduced.

So try to charge it 80- 90 % and then use it. There is no Danger of battery explosion so keep on using it.

Because there are some cases of hoveroard explsion due to overcharging of batteries.

But the new models of are UL certified. So many of the battery faults are rectified.

Batteries used in hoverboard , tabs, mobiles all are Li-ion batteries.

If they are not UL certified then there may be chances of explsion. So Purchase only UL certified batteries.

Try to charge you tab to 80-90 % only and then remove the charger.
[General Accessories] rohnallen:
Hoverboard explosion in year 2015 due to overcharging of lithium batteries.

Lithium batteries are compact in size with large power, and they will get heated up early.

So try to avoid charging of batteries up to 100%.

New models of hoverboard are with UL certified batteries.

UL certified batteries are safer to use.

manufacturer using lithium batteries due to its low cost and compact size.\

example: Hoverboard prices with lithium batteries are lesser as compare to other hoverboard.
[General Accessories] gerent:
Thanks a lot for this thread. Only lately I've been using my phone as a dashboard cam, so battery health has been becoming a concern.
[General Accessories] Bakeryhammy:
Not to charge all the time

The battery of hoverboard is similar to the one in cell phone, just don`t keep charging all the time but remember to check out the remaining everytime before you ride, the battery remains around 90% is recommended. If you want to get one, also pay attention to the UL 2272 Certified and famous brands as well as the reliable buying platform, such as the collection of cheap hoverboard with high rated in Amazon->>

I just got a stick vacuum cleaner that runs on a lithium ion battery. I had hoped to have a vacuum that I could quickly grab and use for short periods. Instead, the first statement in the owner's manual is, "To reduce the risk of fire, electric shock, or injury, remove battery from appliance when not in use." Seriously?? How big of a risk is this?

Few tips when you use 'Lithium Ion Battery'

1. Keep device away from direct heat or sunlight.

2. Don't talk on the phone while it's charging.

3. Do not use cheap chargers from no-name manufacturers. Cheap chargers have several drawbacks.

finally a charge limiter for Android

for Android phones there's Chargie - it bounces charging between two levels that you set, so you never practically charge to 100% unless you want/need to. That practice alone increases battery lifespan dramatically. Just google for "chargie stick" and see what it's all about.

I am charging my S10e phone on usb port of pc very slow overnight.

Pluged it in 11 pm and it says 7 hours to complete charging. When i wake up battery is full. Not standing long time full on charger.

Also using fast charge when needed..

Phone counts charging cycles.

Number of cycles is lifespan..

Phone info apk:
[General Accessories] manabsac:
Why use USB of PC for Charging S10e?

Your S10e has 3100mAh battery, why'd you use the USB of PC for charging which can give ~500mA?

Theory says it'd take 7.47hrs for 0-100% charging.

The supplied 15W charger with S10e would take ~78mins only.

LiPo batteries won't last longer with slow/trickle charging or any other advantages in this choice of overnight charging of yours.

Far better for your S10e LiPo Battery will be 10-80% charging which will take ~43mins. I'm sure you can find 43mins in ~16hrs of Your awake period for charging.

Your PC has to be ON (maybe doing something useful); it can't be even in Hibernation.
[General Accessories] tinko975:
my pc is turned off over night, but rear usb ports are always on power, attached on motherboard, i never disconnect desktop pc from main power source, to be completely off because using it every day for work.. it is not hibernated, i shut down windows system to off.

i was wondering are there some negative impact on battery life and capacity if it is charged that way instead fast charging? are there negative impacts on battery when is using fast charging? on samsung and some devices you can regukate or choose between regular or fast charging, but on some devices like Xiaomi and ONEplus i think only fast charging is possible, slow not.

because i know many people charging phones overnight on normal chargers (2A) and it is fully charged for 2 gours and than stays on charger another 6 hours without purpose. it is easyerst way for most people because they dont think about phones, just use them and have no time or interest to pay attention how is charged or when, etc. like a driving a car and take fuel on gas station.

i imagine it is less harmful for my phone to charge it on lower amps for entire night, than on regular amps for 2-3 hours on normal slow charger and leave phone another 5 hours connected to charger without charging..

i knew tip #3 as my laptop batery is connected to AC for more than 3 years now and still lasts more than 1 hour. So this also kills the idea that the batery shouldn't be at 100%. Experience teels me that it can and should. But i had no idea about tip#2 and was very good to know.
[General Accessories] Helmoot:
Hopefully This will help a little (I'm a Li-ion/Li-ion polymer battery engineer)

The main things that affect a batteries lifespan are the specific charge and discharge regimes (the "work" the battery has to do) and then secondly the cyclic history a cell has undergone (temperature does affect performance so try not to use your phone while in an oven and don't expect full capacity if you keep you phone in the freezer)

-so to simplify/generalize if you have a phone that uses the entire battery capacity in 5 hours and you put that same battery in a phone that uses the same capacity in 10hours (a less aggressive discharge), the battery will also last for more cycles and have a longer overall lifespan. (it gets complicated, when you consider that it isn't a constant discharge, in reality there are high and low rate times based on what the phone is doing, and there are differences in a battery manufacturers chemistry that may offer advantages for a phone that has higher rate demands or a phone that has a lower peak rate, but targets longer run times)

Soooo basically- not all lithium ion batteries are the same, don't compare a manufacturer's battery by how well it performed in another phone, I agree with the post from above, the less you use the battery the longer it will last :-)

Most lithium ion batteries nowadays don't suffer the "memory affect" (I've personally test a lot!!!)

The person who wrote the article stated "Your lithium-ion battery starts dying the moment it leaves the factory" I believe they may be thinking of the slow process of self discharge...basically the 2 active parts of the battery aren't "perfectly" isolated and Li-ions are able to travel even when the phones not in use... I'd suggest they took some liberties with the term "dying"

1 last thing...it's a common misconception that a particular phone has a poor battery when the phone can only run for 2 hours on a full charge for example. There's most likely a mismatch in the phone manufacturers understanding of the user's typical phone usage... software /power management maybe not optimized...

unfortunately, it's hard to sum up what's the best way to take care of your battery and I give the author a thumbs up for trying but as you see it's a more complicated system than that...
[General Accessories] show-p1984:

Thanks for sharing. However, in order to increase the everyday life of a battery in smartphones, there is a guide that recommends full drain of the battery and then statistics reset. Is it OK? Aren't these matters in contradiction?
[General Accessories] Xenova:
Thanks, Mate.

Nice information.:D
[General Accessories] Xenova:
recommends full drain of the battery?

The logic of disciplined charge / discharge applies to older type of battery, but NOT on li-ion battery.

Or

If you mean to calibrate the battery. Yes, it is recommended but not necessary. And a full discharge once a few months is claimed able to recaliberate the battery reading gauge, and by once a few months won't hurt your battery so much.

Most of the battery nowadays have a smart circuit, it shut down you phone not really at actual 0% but it still store some so that the battery cell not damage by overdrained.
[General Accessories] AdamOutler:
Something to add... Your battery is "optimal" at 70%. Never store a Lithium Ion battery at 100%. It will only degrade it. 70% is the magic number and the place where a Lithium Ion battery is happiest.
[General Accessories] AlanB412:
Great post, I've been having arguments with people about this exact topic for years. I'm glad this article was able to sum it up into quick, relatively simple, points that I can beat my opposing debaters mercilessly over the head with, without having to get too technical about it.
[General Accessories] Xenova:
Your battery is "optimal" at 70%.

THanks, Mate.

I heard a lot about to minimize the duration of keeping the battery at high voltage or full charge, as the corrosion activities within the battery is relatively high, thus the it reduce the life span of the battery.

But now i learnt where exactly is the "magic" number. Nice info~
[General Accessories] BusterChestnut:
reconditioning

What about reconditioning using the whole charge, unplug, powerdown, charge until green, boot, plugin until 100% and repeat 7-10 times. I have heard this gets good results in a battery that is exhausted.
[General Accessories] shithead:
Well well..Learned a few things :) Thanks for this post! :D
[General Accessories] cta.smith:
Very informative. I typically charge my phone every night and run it off the battery all day. Battery never gets under 15% so I should be good.

[General Accessories] AdamOutler:
You can't recondition a lithium ion battery. That will shorten it's life. You relearn it's parameters. Lithium Ion batteries are usually accompanied by a circuit of some sort. The circuit's job is to keep it from overcharging and undercharging. Sometimes after repeated under-cycles the circuit will learn a new pattern and requires recalibration
[General Accessories] choiia:
Thanks for this post. Learned something new.
[General Accessories] clouds5:
Thx for the infos :) I'm wondering though. There is this talking going on about battery calibration and stuff on a rooted phone by deleting the batterystats.bin. Does anyone know here how this file works exactly and what its purpose really is? Does it even make sense to "calibrate" it (by deleting batterystats.bin) when the phone is charged to 100%?

Is there a way to check if my battery is still at its maximal capazity? Or if i damaged it? Happened to me some times (like 5x) that my phone ran out of power when i was on the fly and i couldn't charge it before it died. Did I already damage my battery because of that?
[General Accessories] androidbryce:

[General Accessories] Viper89:
@ Xenova do you have any battery info on Li-Po type battery's?
[General Accessories] warlove3:
Thanks for the tip...
[General Accessories] Xenova:
Let's wait for experts answer your first question. I wanted to know that too :rolleyes:

To check your battery capacity:

1. Find out the maximum capacity of your battery (mine is 4.2v)

2. Try to use "current widget" or "battery monitoring widget" or "battery caliberation 1.2" in the market to read your battery's voltage value

3. E.g. my 100% will be around 4.119v to 4.2v

4. Overcharge (higher than 4.2) is bad for the battery too

Already damage?

1. Perhaps yes, at least to certain degree

2. But most of our battery (esp. original) have circuit inside to prevent overdischarge/overcharge. So when it shut down by itself. It is not actually 0%. but it actually still store certain level of current to maintain and protect the chemical cell in the battery. The damage have been reduced.
[General Accessories] FeelMyMagic:
Thank you for the information in this post. :) It's no wonder some see varying performance from their phones when it comes to battery life. Between it's charge cycles, voltage, and power consumption of varying applications, it's important to keep some of this stuff in mind.

Thanks again! :)
