Hi, I just ran powercfg /batteryreport in CMD. The generated report states that after 30 charge cycles, my full charge capacity has dropped to 27,646mWh. the designed capacity is 31,502mWh, so my battery lost 12% of capacity in just 2 month!!
does your surface also suffer from serious battery capacity decrease? please run "powercfg /batteryreport" in non-elevated CMD and look at the report in C:\Users\*username* please post your result including full charge capacity and charge cycles.
Thanks!
mine is unchanged, reporting 16 cycles. I got the Surface 12/17 so I'm a week shy of two months myself.
I don't let my LiOn batteries deep cycle (drain down past 20%) if at all possible, as this reduces their lifespan.
Yeah my battery report says the same thing, even though I haven't noticed any lifespan decrease yet.
Mine has also dropped from 31,502 to 30,444 and 3 power cycles. Surely the battery can't be degrading already?!
At 34 cycles, mine has settled from 31.502 Wh to 30.214 Wh. It is very slowly losing capacity still (was at 30.740 for a few weeks in January) but seems to be mostly holding steady. The noticeable drops correspond to deep discharge cycles; I'll endeavour to avoid those.
Mines at 28472 with 38 charges. I got mine at launch 10/26/12. This is scaring me. Coincidentally I have noticed a decrease in battery life and was wondering if it had to do with the jailbreak as that is when I started noticing it.
47th cycle now, I still have 30,281mWh. I got my Surface RT at around 25th Dec.
29,415 after 47 cycles. Pre-ordered mine, arrived around launch date. This does seem very weird, batteries really shouldn't do that. Anyone have any experience with getting one replaced? Hopefully this isn't a problem Microsoft wont acknowledge.
cant seem to find my stats.. it only says mwh without numbers.. what the hell?
Mine seems to be worst here. After 24 cycle count, I'm down to 26,729. I do let the battery drain all the way - may be that's my problem.
I've had my Surface since Oct of last year.

That might be the issue perhaps, I have never allowed my battery to drain 100% or 100% charged for too long.
Mine is still at 30k range despite 49th cycle
I am extremely upset about this - in only 25 cycles, my battery capacity has gone from 31,502mWh down to 24,154mWh. And to top it off, I have been wondering why it seems the battery life isnt that good anymore. Is this permanent, or can you condition your battery by not allowing it to drain as much?
I have been letting it drain all the way down, and when i charge it, i plug it in overnight. Obviously this is the wrong way, WTF - you would think that they would tell you about this in manual, etc.
To be fair, this has been common knowledge for literally as long as laptops have been using Li-Ion batteries (well over a decade). I agree that it should perhaps be better documented for those who have somehow never before encountered a LiIon battery, but acting like this is some never-before-heard-of consequence of hard-draining your battery is... weird.
Leaving it plugged in all night is fine; the charger is pretty smart about handling that. Just try not to let the charge level drop below 10% (ideally, not below 20%, just for some safety margin) and you should be fine.

The charging system is smart enough to not overcharge, so you don't need to worry about this.
No one should be "reconditioning" or deep cycling batteries anymore - at least not if they are LiOn/LiPoly.
Got mine 11/4, 22 cycles, down to 25,xxx. Pretty disappointing considering I don't let it die all of the way. I'm hoping this is just an OS reading issue.

I turned off all low battery alerts and forced the battery to run completely dead, and recharged, and now mine has gone up a few points to 28,579 from 28472, with 39 charges, so I think it needs to be reset once in awhile. I however was not aware that leaving it to charge all night and using while plugged in could hurt the battery as others said - Still question that logic. I also have used it to the point of turning off but because Win8 has adjustible power options to force it to turn off when it reaches a certain battery level, I am not sure any of us run the battery down to nothing.
i just wish we could get a stupid battery ap/utility that would tell us battery life left in percentage or something to help us monitor it better.

Got mine on release, I've fully discharges mine about 3 or 4 time mistakenly, cycle count 49, full charge capacity 29,985, given this I've altered my battery plan to give a warning (low battery level) at 20% rather than 6% and to shut down (critical level) at 15% rather than 3%.
Oddly enough, my battery plan has never been adjusted so theoretically it should never drop below 3% yet my battery report clearly identifies it dropping to 1% at one point.
So, are you guys telling me that I should try letting it drain down to 0 and then recharging it to see if it is simply an issue with calibration?

I want to buy a powerbank but my friend said that after few months of usage it will badly affect my battery life. I want to know if it is true or false.
Thanks for all replies
Can anybody help me?
It really depends on your charging habits. Batteries die more and more every full charge cycle. Its usually a better idea to invest in an extended battery which often times is cheaper without the hassle. If you recharge twice a day and charge normally once. Theoretically, your battery will degrade 66% faster then one charge a day. But rarely will you be charging 3 times a day. Expect a number closer to 25%-35%. So if the average battery's optimal life takes a year to degrade, expect yours optimal life to be roughly 9 months. Of course at 9 months, your battery doesnt just stop working. Over each charge and month, your losing more and more charge capacity to the point where its inconveninet because your recharging so much. My battery is almost a year old and ive already ordered a new one due to the crap battery life. To tell if you need a new battery, try to spin it on a flat surface. A battery that can hold a charge wont spin since its flat. A battery with lumps and round points will because it cant hold a charge. So i would recommend a SLIM extended battery, they dont require an extended case backing(makes your phone a boulder.) Hope i was helpful!
So my maxx will drain to 1% battery in about 3 days with 3 hours screen time. The thing is once I hit 1% it can stay on 1% and not shut off for hours. Right now its been on 1% for about 7 hours, I have a youtube video going just to see how much longer it will go. Its been playing a youtube video now for about 20 min on 1%.
I just got this phone last week, is this because the system hasn't fully calibrated the battery? Or is the battery defective in some way? Its kind of annoying because you think you are out of battery but it keeps going so I don't really know how much battery I have.
Definitely not normal. I'd do a factory reset to eliminate a software issue and if the issue persists seems like it must be a hardware issue, exchange it
These sound like calibration issues. Can you fully charge your battery and then leave in on the charger for awhile -- like an hour or more? That should calibrate it correctly.
I have never nor will ever let my battery get that low. These batteries don't like to be drained and then fully charged it's not healthy for the battery. I don't let my battery go below 30 to 40 percent if I can help it. Most of the time I let it get to about 50 percent then I charge it.

not to be rude but where is you information or evidence backing your statement? this goes against everything i know and i certainly always allow my battery to fully die then i fully charge it over night while it is off, i believe charging at 40 percent fools the battery into thinking that is the end of the battery's daily life span and therefore dying prematurely due to it believing that 40 percent is the end.
I do not have any real evidence except i've gotten exceptional battery life with my Ultra after allowing a full cycle (draining all the way and then fully charging while powered down)...i have gotten just under 32 hours with 4 hours and some odd minutes screen on with about an hour of voice calls and random other usage such as tapatalk browsing, internet, texting and maybe some email or youtube....i occasionally play some games like the new CoD Strike Force

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
From the second link (emphasis mine):
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

Coming from a Gnex, I have a charger within 3 feet of me everywhere I go. I'm trying to break myself of the habit of plugging it in but mine still gets a charge at some point during the day, if only in the car. It has always been my practice to let my phones run down almost to dead maybe once every couple of months. I feel like it keeps the phone's battery meter calibrated although I have nothing to base this on.

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.
Actually what happens when you leave the phone connected to the charger is that it stops charging completely. I do not think it affects battery life in any noticeable way, unless you leave it for hours connected maybe.
If you're using your phone quite heavily surely you will be constantly charging if the optimal usage is between 50 and 90% of charge?

What will happen is that when it drops to 99%, it will charge back to 100%. Over the night, it could happen many times. It is a circulating advice for a long time now: don't let your phone on the charger for the night.
I must admit I try never to charge it overnight. I'm managing to get just over a day of use before it needs charging.
but the proof is missing, there are many such fairies in the internet, even if, after 2 years, most buy a new phone anyway. and so long holds each battery! With my s6 I still get over the day. and charge it always over night!

I agree 100% with the above quote. There is no real proof one way or another. It is all speculation run amok.
The only fact is that the battery will slowly degrade over time. THis is what the OEM's want!
They make it very difficult to replace the battery so that you will buy a new phone... plain and simple!
Any phone built within the last two years is more than powerful enough to do anything needed for communications... the reason cell phones exist in the first place. I always charge my phones (when needed) overnight. They all last as long as any other phone.
I too am caught in this ridiculous merry-go-round of buying a new phone all the time because we want to sell them before the battery gets too old.
Progress...argh.
There's a reason why electric vehicles don't use 100% of their battery capacity
But worrying about your phone's battery life is too much of a hassle, I'll have a new phone by the time this one is useless
And since the battery is not user replaceable, it has the same warranty time as the phone. If there are problems, samsung can replace my battery

S6 is only $150 on Swappa. Mobile phones have $h1t for residual value. Trading up to the latest and greatest isn't something everyone can afford to do every 2 years.
So, what you're saying is, in order to keep my battery from only lasting a few hours and having to charge it more frequently a couple years down the road, I should start to only use my phone for a few hours at a time and charge it more frequently right now....
How much will the battery replacement cost at Samsung?

Charging your phone to 100% won't harm it. Letting it die at 0% though can harm it. Lithium-ion batteries don't like dying, but charging them to 100% won't hurt it, in fact leaving it plugged in for hours, even days afterward, also won't harm it. Chargers stop charging devices at 100%. Phones will be fine as long as you don't let them completely die. If you've ever wondered why they will still tell you the battery is "dead" when trying to power it on after it dies, that's because it's not "dead" so to speak, but the phone shut off to prevent damage to the battery.
In short, letting your phone die CAN harm it, but usually, it won't, because phones power off with some power left in them due to a "dead" battery, to protect the battery. This is why once they die you can still hold the power button and it will tell you its dead. Finally, charging your phone to 100% won't hurt it in any way, as chargers stop charging devices after they reach 100%.

WRONG.
Lithium-ion suffers from stress when exposed to heat, so does keeping a cell at a high charge voltage.
Most Li-ions charge to 4.20V/cell, and every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Too many users have no idea about the facts of Lithium-ion batteries, sadly. Don't spread false information, learn the facts. Charging to 100% IS stressful for any Li-ion battery. The last 10% are the most stressful when charging. That's why Sony invented "Battery Care" which will charge the last 10% very slowly exactly for this reason.

Technically speaking,
A source brought up a couple of months ago says that in a year, approximately 300 charges and/or more, you will lose about 30% of the year. Charging it from 50% and higher will burn out the battery even more. It's better off letting the phone go to a certain threshold of ~>15% of the battery, then charge it so it could have more longer life in these years. Its beneficial for longer life, but day to day wise no. But long story short, i don't really agree with the method you recommend us doing.

This is incorrect. When your phone fully dies then charges to 90-100%, it does a battery cycle. This cycle is worth doing from time to time to keep the safety of your device and battery from not overheating.

Hi!
I have a question.
My S22 Ultra will arrive this week and I don't know how to charge on the first couple of days/weeks.
There is the option to protect the battery and don't charge over 85%. should I use this option on these first days or charge it until 100%????
On my daily basis perhaps I'll use that option, what do you think?
Thanks a lot.
i keep it at 85% setting ever since it was introduced
PLEASE HELP!!!

Just charge it normally. You'll definitely need to have it on the charger during the initial setup.

You can use it straight from the go and not worry about anything.
My tired and true method when I first get a new phone is by calibrating the battery to run for optimal usage. I let the battery drain the first time until the phone shuts off and then charge it to 100%. I do this again one more time. After that I just charge it to 100% and let it drain and top up however and whenever I feel like it.
There's a couple of reasons for this. First battery life isn't a strong suit for this phone unlike say an iPhone 13 pro max so I'm not going to waste my time running towards a charger all the time. Secondly, the benefits of charging between 75-85 percent and 20-25 percent is negated or lost on me because I'll most likely move on to a new phone by the time the extra battery life that I've managed to squeeze out can be taken advantage of. Now if you're likely the type of person who's going to hold on to his phone until it dies or will be willing to change out the battery to continue using it, then by all means go ahead and toggle the option and follow that road..
Hope this helps..
Plug it in, charge, use it - then plug it in again etc... smartphones aren't made to last forever, after a few years they all become an obsolete junk - that's my personal opinion, you can follow any charging routines you like.
Minimum start charge battery temperature is 72F, 82-90F is better.
Never start charging if below 40F.
Best not to drain past 20%, 30% is better.
72% is a better top off number.
Regardless of how much you charge it, observe the minimum start charge temperature.
Once a battery has reached 80% of it's new capacity it is degraded and should be replaced to prevent a failure which can heavily damage the phone.
A degraded Li is more likely to fail.
Any battery swelling (rear cover bulge) is a failure, do not charge, replace asap. A failure can happen at any time in the battery's life cycle and they can happen fast.
I now replace my N10+ batteries every 1-2 years, routine maintenance.
