Hello, is there a way to have the charger connected but only use it as an external power source like on laptops without charging the battery? I use my tablet often near the charger and don't want to start the charging process 5 times a day.
Thanks!

I don't know, but I'm curious why you want this? Did they put a Nickel Cadmium battery in your GT10?
I want this for the same reason as on lenovo laptops. With this feature you can save some charging cycles and the battery would last 1+ years. On my dell with the charging plan same as my p7500 the battery was dead (less than half capacity) after 10 months. And I do not necessarily need my battery charged to 100% all the time..

So they did put a Nickel Cadmium battery in your tablet? Those sneaky bastards! I must have gotten lucky--mine has a Lithium ion battery.
No it's Li-Ion, don't really understand why you think that Li-Ion is not impacted at all...

Sorry, I'm just having a bit of fun messing with you, but you need to update your understanding of rechargeable batteries.
Ok, no prob I realized that you don't know the answer, can you at least share your opinion why this looks like an unnecessary thing to you and prove it? (link)

I think that slack04 is refering to the properties of Li-Ion batteries. These are very different from the older technologies like NiCd or NiMH.
In short ... Li-Ion batteries realy love to be charged all the time. Keeping them attached to a charger all the time or multiple small periods of time will not hurt them.
There are only a few things that will realy hurt Li-Ion batteries:
- time : Li-Ion batteries degrade over time, even if they are not being used. You can expect a Li-Ion battery to work OK for about 2 years. So, never buy second hand Li-Ion batteries or batteries that have been stored in a shop for some time.
- heat : do not keep a Li-Ion battery in a hot place (like your car in the sun) It will severely reduce its usefull lifetime.
- undercharging : If you let a Li-Ion deplete to a too low level, it can be damaged beyond repair. But, our tab will turn itself off way before that low level.
So, just let it charge itself as much as it can.
This is not true for the older technologies. I think that's why lots of people are still thinking that very controlled charging cycles will prolongue the lifetme of their batteries.
Cool, so we can use tab connected to sector all long as we want with ion battery! ?

Thanks a lot for the link, it's interesting reading that the best would be keeping the battery at around 40% charge.
BTW is it a Li-po or Li-ion battery in galaxy tab 10.1?

Read it again, and don't post stuff that will confuse new folks. Here's a quote from the article:
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."
slack04 > I've read the article very well... and I feel that your posts don't add that much value to this thread. maybe you could read it again as well.
Please check the table from wiffeltje's link. It clearly states that at 25C at 40% charge the yearly loss in capacity is 4%, and at 25C 100% charge level it's 20%.

I don't want to make it even more difficult, but the table you refering too deals with 'storage'. That's a good table to follow if you need to store your device for a couple of months without use. Then it's best to have a 40% charge.
For normal use the simple rule is : keep it connected to the charger whenever possible.

Hello dear members
I'd like to ask if an everyday charge will harm my battery.
It's my first week with my phone, and I can't keep my hands off it
As a result, battery runs out every day!! So I charge it...
Will something happen to the battery?
thanks in advance
This phone has a litium ion battery. They don't have a memory effect but in the first time they need some time to become the full potential. So it doesn't matter if you charge the phone every day.
Sent from my GT-I9100 using XDA App
Thank you so much!!!!
It's a relief
To maintain better battery life it might be a good idea to make sure that u dont fully drain the battery
That shouldn't be a problem the most battery's should have electronic inside to prevent this but I can't guarantee it. You can read also the Wikipedia article about lithium ion batteries it's quite interesting.
Sent from my Nexus S using XDA App
It is better for you to charge daily and often when the battery still has charge and not leave it until the battery is totally flat.
Thanks so much everyone Point taken
I'll never let it fall under 10%.
Well, Battery is average. If it weren't for the 2.3.3 bug, it would rock! In order for it to be normal, I keep ****ting Services.(under Services menu) like Voice talk, SocialHub(which drains a lot of battery) etc
Anyways, thanks to everyone

Isn't it actually opposite, I mean somewhere I heard that if a Full charge is given after a Full drain then the battery gets conditioned (optimized I think), can't remember the source but I do remember the fact.

I'm glad this thread exists. I'm so used to running a battery down to the minimum before charging it that I probably would have been in that habit for my SGS2. I'd actually come here to ask the same question now I've been through my first four or five "full" -> "red" -> "charge to full while off" cycles.
Is it confirmed both from the SGS2 & LION technology point of view to now keep it charged up, even if using only half/quarter charges etc to do so?
My battery is giving me around 40 hours a time so not too bad but I'd like to keep it running as well as I can.......

Nope. Li-ion batteries these days prefer constant top-ups and full drain actually kills it faster. Totally opposite of what people have been taught over years of NiCD battery use that I've got friends who absolutely refuse to charge their iPhones unless it's at 10% or less. Their loss.

No that's only good to do once in a while. Full discharges daily put stress on the cells and wear out li ion batteries quicker.

Yes it's common for all lithium ion batteries to charge as often as possible. Its true for all phones on the market today and quite a lot of discussion on this is all around the web.
Also a replacement stock battery for any cell phone today is around 20 dollars, so really you can't do much wrong since its so cheap to buy a new OEM battery replacement.
Thanks for the replies. I think this will catch a few people out so hope the thread doesn't get missed amongst all the other battery ones!
Looks like I'd better change my charging habits!
I've come across some people that say the GS2 battery should not be drained completely since for this type of battery it's not good.

Pants - is the only way to describe that post, false info.
It does no harm at all to fully discharge, more problems are caused by giving regular, short charges, than 1 long full charge so i wouldnt believe that.
He also says to charge it 8-10 hours, that total rubbish as well, these batteries dont need 8-10 hours to prime, on average 3-4 hours for a full charge is more than adequate.
I think few year back batteries were far inferior and did indeed need longer charging periods, but not any more, and if ya flash roms a lot and need to calibrate your battery after flashing to a new custom rom indeed part of the calibration process is completely running down the battery, my s2 is well over a year old and has been drained flat many a time and i still get 14 - 20 hours out of it on average, which is damn good for any smart phone these days, That post is on a HTC Thread by the way, Htc notoriously have batteries with a crappy life span, i had a wildfire s, used to get about 6 hours out of the battery.
I don't think that's true.

Mine was a rhetorical question, but it's all good, dude.
Lol, short version: Depending on the battery type you will want to drain it completely before charging or never drain it completely. Let it charge fully overnight or it only needs a few hours.
Seriously, do some reasearch on batteries. Figure out what types there are, how they are different, and what makes them different. each has advantages and disadvantages.
Every battery type is a little different. For our phones will be different than for your rechargable nicad batteries at home, or the batteries in your remote control vehicles.
Bottom line: We COULD tell you, but that would be defeating the purpose. Instead we are pointing you in the right direction to acquire the knowledge yourself. Happy hunting! let us know how it works out!
In simple, it actually causes more harm discharging the battery to empty.
There is alot of do's and donts to preserve the battery,
Info:
The Li‑ion charger is a voltage-limiting device that is similar to the lead acid system. The difference lies in a higher voltage per cell, tighter voltage tolerance and the absence of trickle or float charge at full charge. While lead acid offers some flexibility in terms of voltage cut‑off, manufacturers of Li‑ion cells are very strict on the correct setting because Li-ion cannot accept overcharge. The so-called miracle charger that promises to prolong battery life and methods that pump extra capacity into the cell do not exist here. Li-ion is a “clean” system and only takes what it can absorb. Anything extra causes stress.
Most cells charge to 4.20V/cell with a tolerance of +/–50mV/cell. Higher voltages could increase the capacity, but the resulting cell oxidation would reduce service life. More important is the safety concern if charging beyond 4.20V/cell. Figure
Discharging:
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.
And may i point out, this is a community, People ask questions and peoples feedback, the web is not always correct and nor is the information you find.
It takes more effort to argue with someone and to point someone in the right direction, instead of just answering there question.

But may I point out that all you did was copy and paste text from this page, which donalgodon linked in post 4, and again, I feel I must point out, was actually one of the results in the Google search I linked him to.
The point I was trying to make, and seems lost on you, is teaching people how to look for stuff on their own. No one should just expect to be spoon-fed information. That is lazy to just post a question on a forum, sit back, and watch the answers roll in. You should do your own legwork and research.

Hello
So my GS2's battery was seriously getting crappy, and I ordered a new original battery (more expensive, but I really wanted it to work properly). Before the replacement, it was all over the place, and I think I may very well have a phone that's seriously confused about its battery options.
Thing is, after the replacement the phone isn't charging the new battery properly (AFAICT). If I'd have to venture a guess, I'd say it charges it to 33% and then it states 100% full.
So, I get just a handful of hours of regular on-time with this new battery. Sometimes the phone hard-dies when saying about 50% remaining, other times it actually says something like 2% remaining, then dies, but still awfully far from logical, considering the fresh battery replacement.
I've searched for how to calibrate this thing, and most results simply recommend the "fully deplete, then fully charge, extract, reinsert, etc." method.
However, this does nothing to help me.
I read somewhere that for some custom ROMs (Dorimanx kernel?) you could do a more "explicit" recalibration, but I'm not sure if that'd work — as I'm on ParanoidAndroid ATM, and here I don't have such option.
So... Does anyone here know of any more "legitimate" way of recalibrating? I really don't want to buy a new phone, as these days I don't see any phone I really want to buy...
TIA,
Daniel
new batteries require a few charge discharge cycles before they reach max capacity, you may need to leave it on charge for longer than the "charged" info appears.

Thanks, Sparks, but I've already done this many times. I've had the battery for a couple of months now, but I really need to figure out how to calibrate the phone so that it starts behaving "normally" with my new battery...
Let it die, juice it up while it's off, take the batt for 90 sec when it hits 100% and put it back in?

Something definitely needs calibration, and yes, of course it's not the battery itself when buying a fresh original battery does not fix one's battery problems, it must be some battery controller somewhere. I just started a new job, and my CEO has a Galaxy S3 which started having battery troubles. Like me, he replaced the battery, and like me, nothing changed.
In the meantime, my S2 died completely, so problem "solved" I kinda feel retarded for planning on buying a Note 3... Probably ought to run from Samsung devices altogether...
Is it even necessary? Some claim that I should give them an initial charge for like six hours to even a day, while others don't. In the case of a just-purchased Allwinner-powered tablet with a Lithium iron phosphate cell, do I really need to initialise it?

It's lithium ion, not iron.
And no. There's a lot of myths and misinformation about lithum ion and polymer batteries that are holdovers from NiCad and NiMH. You don't need to peak charge it, you don't need to drain it to zero, you don't need to condition it periodically, they don't have "memory" like NiCads did. In fact, if you're going to not use it for a while, it's best to only have a moderate charge rather than drain or fully charge it.
Charge it when it needs to be charged, use it when you want to use it, and don't worry about anything.
I would like to explain to you myself how smartphone/tablet charging works. But this was already solved by recognized XDA Senior Adam Outler.
As i have not yet reached my 10th post legibility. I'm just going to leave the titles of the vidoes, plus one by Marques Brownlee(MKBHD).

http://techlife.samsung.com/tips-keep-smartphone-charged-1059.html
Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

Wow I did not know any of this. I will be following this thanks for sharing.
how long is the battery lasting if you are only going down to 50 and up to 90?
Gees! Below 50% really. I would tend to agree somewhat. I never let my phone fall below 20% and usually charge until 97% more or less. But 90-50. I don't want to be walking around with a battery back. I need my phone to last all day and 40% of the battery just won't cut it.
Xuck that !! I have a 3000mah battery for a reason if it goes then it goes ill most likely have another phone by then.Not gonna sit here to nickel and dime my usage that's not why I got this phone .
GM makes the Li batteries last in the volt and bolt 10 years by not letting the car drain the batteries more than 2/3rds down, leaving the batteries at 1/3rd charge. Tesla does it too.

Nah, I don't own my phones for more than a year so this doesn't apply to me. I'd rather keep using it from 100-1 just like I've been doing for years. I wouldn't be able to stand only getting an hour of use and charging it 3 times a day.
This battery information applies to all devices that use this type of battery be they Samsung or other brands. Its not just the Note 8. It applies equally to your Oral-B tooth brush! :laugh:
Ryland
this is a good habit to charge often at 50%. i usually let the battery run down to like 20% or less then charge. then when i have to go somewhere and i cant play with my phone anymore cus i worry i going to run down the battery.
Question are the "300-2500" charge cycles just as it says? I mean if I put it on the charger in the car for a 10 minute drive is that a cycle along with an overnight charge? If it is we should really only be putting it on the charger from the 50-90% with a guaranteed fast charge time of at least 30+mins to get the maximum charge cycles for the lifespan?

This was a really well written down to earth article about battery care. Thank you. I still have friends, family, and coworkers that insist on running their batteries to 0%. I can't convince them otherwise. Although my batteries degrade, it's never been anything easy shattering. Just notice an hour or two shaved of over a couple years life. As the article states, there is no way around this and I won't be a slave to my battery. In that note, I top off when I can.
My battery on my old phone tended to get to around the 40% at the end fo the work day, then I'd plug it in usually around the 20-30% and it still lasted 2+ years 'til I got a new battery. Now it's about 50% at the end of the day. But with Fast Charge, what do they expect people to do, plug it in for an hour, then unplug it, then go to sleep, wake up with 60% battery, go to work and then charge it for an hour when you get there?
The lie of requiring a non replaceable battery for water proofing is also an issue. Forced obsolescence sucks....

Too black and white.
It is possible to offer some water resistance to a mobile that has a removable battery, S5 for eg.
In general such water resistance is small and is often abused by the owner causing problems. Hardly any owner reads the instruction manual that outlines what ones device can and cannot do, what the IP rating means in REAL terms etc
"Forced obsolescence" mmmmm, a battery can be changed in the Note 8. I understand your point though.

this has been around for years. Doesn't make it very convenient to use nothing below 50%! I'd need at least an 8000 mh battery!! Therefore Samsung IS using too small a batteries in its top of the range device!

Totaly agree......
We then have to ask 'ourselves' WHY! Who forced Mobile brands to make anorexic devices? WE DID. We wanted thin small large wide slim ...........we got it and now pay the price.
I personally don't care if the device is thicker with a larger battery, for me its not a problem. For so many size was a major issue so the manufacture's listened and came up with these ultra thin mobiles that are vulnerable to dropping and breaking etc. off topic.
I find it totally bizarre that we spend mega bucks on such devices only to find we are educated to use them on software that reduces said mobile to the performance of a phone costing 100€! I may add many posters where disappointed when the Note 8 didn't have a 4k screen! Can you imagine the battery issues then?
Now we read this Samsung article and find we would need to charge our mobile several times a day as well as run it on a vastly reduced software programme. In reality that article is saying the battery is only operating efficiently at 40% of its total capacity before we start to degrade its life! Its all so absurd. What are we doing here folks?
Only one answer to this, either drop the performance OR vastly improve battery technology and fast.

I'm not sure how usefull this is for the new samsung phones though, as the release of the S8 Samsung improved the battery.
Samsung Mobile R&D VP Bookeun Oh told me, "I focused on maintaining the durability of the battery over the long term, over hundreds of charging cycles. For example, after approximately six months of normal usage, the battery in the S8 will outperform previous batteries. While most batteries hold about 80 percent of their charge after two years in usual cases, this battery should be capable of 95 percent of its original capacity."

PC mag S8 review
I am sorry but i will use my phone all day and charge overnight. If you can't use past 50% what is the point???? My pixel xl i have had since day 1 and use all day everyday and charge overnight and noticed no real decrease in battery life except a little change with oreo!
Outdated info and not necessary.
0% on your device is still considerably above what is considered the bottom line cell voltage before excessive discharge detrimental affects capacity.
A lot of engineering has gone into these devices to squeeze every possible mAh out of the packs, have a decent life expectancy AND operate safely. There is no need to strive for certain numbers and forcibly change your usage habits. There may or may not be a demonstrably better result long term but honestly is it worth worrying about?
And for removable packs...
Forget it. That's a thing of the past.
If devices had battery life like the Skyrocket, sure I see the NEED for a swappable pack.
But not now.
Having a sealed device makes it feel solid and keeps intrusion protection intact.
Holding an older device in hand, it seems almost laughable today. It creaks and groans and feels super cheap in comparison like some dollar store toy!
