These days smartphones have gotten plenty small to carry normally. so why don't they beef them up with a ginormous batt and make it a selling point?
I think the SGS is the smallest big screened smartphone. If they were to make it Evo sized, double the batt life and sell it as a completely different phone, that would be great! I mean I would think it would be some major bragging right to say "our phone has 200% the batt life of the next best phone".
10 hours of full 3G web browsing/GPS/video playback
70hrs+ of audio playback
on top of all that, maximum batt life deterioration over time will be null because you'll go through MANY fewer recharge cycles.
These phones are all great, but I'm a power user and I'm always fighting my batt. We should be able to have all the bells and whistles blowing at all times.
Thanks for your time/response
Edit: the new iPod has a 3400mah batt. Coupled with the "Peal" which turns the iPod into an iPhone (albeit an ugly one), you basically get an iPhone 4 with double the batt life in a similar sized package...
Edit: I'm dead wrong about the iPod's batt capacity as rajendra82 has pointed out. It was 3.4 watt hour, not 3.4 amp hours. Sorry (for the record, the iPod's batt would be terribly insufficient as a modern phone batt in a smartphone)

The new iPOD touch has a 3.44 Wh battery, which at 3.7 V translates to 929 mAh. The Samsung Captivate has a 5.55 Wh battery, which at 3.7 V translates to 1500 mAh. Since the battery capacity is directly proportional to the volume, a battery of 3000 mAh will be twice as big as our current battery. The biggest phones today (i.e., the EVO and Droid X) only ship with a 1300 mAh battery. 1500 mAH is plenty for this phone to get through the day. Battery life is typically rated at 1000 cycles, which is 3 years assuming a full day to go from 100% to 0%. You are likely to replace the phone in 3 years any way.
Our phones do have large batteries, and as long as you don't have a bad program, have the screen on super bright, or use it as a hot spot, the battery life is going to be good enough for nearly anyone.
The captivate has a HUGE percent of the volume dedicated to the battery already, without using a non standard (non rectangular prism) battery shape the phone thickness would need to greatly increase and have wasted space.
In simpler terms, when your battery is already good for the market, a thinner phone sells more than a marginal battery lfie increase.
What about weight? Does a bigger battery weigh significantly more?
I would love to have a bigger battery or one of those battery cases like my fiancee has for her iphone. I think the above comments are spot on, but i think what companies dont take into account is how much people use their phones for on a daily basis. I dont know about you, but I use my phone a hell of a lot during the day more so than what constitutes as 'just getting through the day'. If im lucky enough to make it through till the end of the day its skirting on the red. A backup battery would be awesome to have!

Sorry, I just realized that. I must have missed the details about the ipod power.
I understand that the captivate technically has the "best" battery, but I do not agree that it will last through the day. I'm using my phone regularly to look up information, text, Gtalk, and make many calls. The phone is dead by the time I get home around 6pm (days start around 7:30am).
the iPad has a "10 hour batt life". My sister has her iPad lying around the house but she and I are much more often on our phones, so why don't our phones have a 10 hour batt life? I think its kinda difficult to use the ipad for 10 hours in a single day seeing that people usually work too. My phone is used for productive purposes usually, so it is very easy to drain it in the 4.5hrs it lasts on any day (not to mention difficult to get through an 8hr plane ride and still have juice to find your way to the hotel when you land). Last I checked, a day was at least 8 hours, not 4.5.
I also realize that they would have to ditch the rectangle/cube form factor of the batt in order to fill the space of a larger case more efficiently (something the iphone takes advantage of). I have nothing against this (or the added weight) and I don't think any other power user would care either.
At the end of the day, a captivate thats as big and heavy as the Evo is a small compromise if it'll last ALL day long and I believe there is a significant market for Android+10hr batt. Unfortunately, the obvious response to that is that I'm wrong since it doesn't exist. So I guess I'm just a crazy person then
Sigh...
Edit: I forgot to mention Virgin America has solved all flying problems with this nifty little thing called a power receptacle in each trio of seats.
There have been at least 10 different claims in the last 5-10 years from companys saying they've found a way to at least triple battery capacity.
so far none of them have made anything...
Have you ever seen those extended batteries that also replace the back cover? They look awful. It's great that the Captivate is so slim and light.
It's unlikely that enough people need that much power every day for manufacturers to implement a huge battery in every device.
Nevertheless, it would be great to have the option.
Third party batteries that replace the back cover haven't been designed by the manufacturer to take advantage of all the space available, they're just made afterwards for the (admittedly few) people who need to stay more than 12hrs without a power source.
If a manufacturer specifically made a phone to accomodate a larger battery, the uglyness+volume/duration ratio would be much better.
Imagine a qwerty slider with a large battery instead of the keyboard: you could live with the additional volume and you could go on for two full days without a powersource.
Personally I wouldn't ever make it without a car charger, I keep a spare battery around in case I need it and even carry a retractable microUSB as a key holder (I use my phone as a music player, the battery drains FAST).
I'm ok with that but a large capacity batt. would let me not have to care about how much juice I have left all the time, wich would be great.

You're not crazy. I think about the smartphone battery problem all the time. It's by far the biggest drawback of a smartphone. Even if you are using it lightly, you still have to charge every night, that is smartphone 101. And yet, if my friend iwth a little feature phone texts me all day, and I text them back all day, there phone... is fine. They can bascially run it all day for three days before needing to charge when it's new. My Captivate (or any other smartphone)... constantly having the screen on? It would be begging for battery after hours. Now of course, we have vastly better batteries than the feature phone, it's just the smartphone is doing significantly more. But still, yes, there should be a way, possibly with non-rectangular batteries, to significantly (at least double) battery life at a not massive cost to form factor and size. And yes, I'm sure there is a market here as well.
Seido is in the development process for a 3200mA battery for the cappy. Won't be long before you can actually see what it looks like on their website

This may be about the captivate battery life but I think some of u are crazy. I run the hybrid r3 rom on my phone and I use it for music; GPS; internet and everything else that is normal and my battery is garbage. I'm sorry but when I buy a phone it should not be dead by like 3 pm

Bigger battery means more weight. Some manufacturers get a little more power out of the same physical size, but if you really want to double the battery, you double the size and double the weight.
Since the phones have no extra room inside, you wind up with a bigger phone.
All manufacturers are trying to balance size, weight and power. It is no coincidence that all the smartphones have near the same size battery.

This post pretty much leads me to believe more is going on than you're saying. With hybrid r3 I was getting two days with heavy usage, also gps isn't functional on that rom, so claiming to use it seems to be misinformed at best

Seido might make some great batteries, but if the batt for the captivate is ANYTHING like the batt for the galaxy S, its absolutely retarded and WAY too big to be practical. They basically just extended the batt brick and extended the casing with it. With the same batt cover, they could have added a whole nother batt right next to the extended batt cuz of all the wasted space.
Not a viable solution IMO. A factory made phone that has a HUGE batt would be marginally larger than the current captivate because they can take advantage of a non-traditional form factor and all the space inside.

Our Captivate doesn't have any extra space, and even the Droid X has a battery of the same size. I am just not seeing the extra space for bigger battery. There is also the weight issue.
Now if maybe the new Dell Streak will give you a monster battery in that big thing.
i agree that a phone with a super battery pack would be nice. me and my friends would always talk about if we could make our own phones what we would want and i always said something that would give me nice battery life so the idea i came up with was this
by default most phones come with a 1500 mah battery
but why not add a non traditional form factor to the rest of the case adding battery to and around the phone like in the area around the camera in the front of the phone around the side of the phone kinda like some of this battery jackets we see coming out for the iphone 4
i think it would add maybe just a built more bulk to the phone i'm still using a tilt so i'm used to carryin a bulky phone
i've always been interested in seeing super cap or ultra cap tech being put into a smartphone figuring if we can't go all day with our battery at least let us be able to get a full charge with in a few minutes ya know
i see ultra and super cap tech starting to be put in remotes were you can charge it in 1 minute to 5 minutes and not have to charge it for two weeks that kinda tech in a cell would be lovely
I, for one, would give up the cool looking indent in the back of the captivate (where the metal cover is) if they would fill that space with battery. It wouldn't increase the size of the phone (much), wouldn't make it bulgy, and I could see it giving at least 50% better battery life.
Even if the phone was blobby, plenty of people are buying Droid phones, and those things are frikin' mon calamari cruisers.

obviously they would have to make the phone a tad thicker and its already so light weight that adding double the batt weight would still keep it weighing less than an Evo
the Samsung Captivate battery is pretty beefy if you ask me, I don't know how they would fit a processor and other components in the phone if they got a bigger battery
Is there any way to speed up the charging process? a rapid charger? external charger where i can take the battery out and charge it in a charging pod faster then it charges while in the phone?
You may have a defective battery, mine charges as quickly as expected. Note: charging via a computer's USB port is always slower than charging from a wall outlet (though it does top the charge off slightly higher), though this rarely delays charging by more than 30 mins.

I understand your pain. When I had the SGS2 (coming from an iPhone), it took almost a half a day to charge up (exagerating). 30 min charge would only give you a handful of percentage. I am a bit more happy with the charging time of the Skyrocket though. Not amazingly faster, but quite a bit.

You can do sooooo much more with an android device that this should be an easy choice unless your a die hard fanboy. I wouldnt use an iphone even if it were free. Sure androids battery life isnt great but any superphone or superlaptop isnt going to be either unless they make it twice as thick to hold a very large battery. Also when you had your iphone i bet you did not use it nearly as much and now you probobly watch videos on youtube and netflix download free music surf the web alot more. So that may be another reason you arent as happy with the battery. Cant do awhole lot with an iphone to drain the battery nearly as much.

Umm.. We talking about battery life here... It's also not "android battery life" (no such thing), it's the samsung skyrocket phone's battery life we are talking about. You can vibrate the hell out of your phone between your legs and run out of juice. But it'll take a long time for it to recharge until you can continue with your vibrating.
As for can't do a whole lot with an iphone: I drain my phone with tower defense games like Sentinel 3. Available for both platforms. Drains battery just the same.
Nobody an iPhone fanboy here (this is xda, is it not?), but then again, I dont drink anyone's kool-aid...

That's why you don't ****ing charge from the computer. Also it is really fast to charge up to around 85%, the next 15% will take much longer due to the way all lithium batteries are made.
Yes, it takes longer to charge up the Skyrocket than it does an iPhone.
Part of this is because the Skyrocket battery is a larger capacity battery than the iPhone battery.
The larger the battery, the longer it takes to charge up.
The bigger your glass of milk, the longer it takes to fill it up.
The larger your cars gas tank, the longer it takes to fuel it up.
Etc.etc.etc.
But in keeping with the thread, I'd like to second the request for any info on fast chargers. We know that USB/computer charges slower than wall outlet chargers (wall-marts). But are there any wall chargers that charge faster than others?
I doubt it i believe the phones hardware only excepts a certain voltage and amperage. So even if the charger was slightly.highrr voltage and or.amperage the phone will only accept.what the hardware allows. You can have an underpowerd charger but to prevent mishaps there designed not to be able to overpower i may be wrong but i believe thats whus up
Why people buy phones with disgustingly crap batteries? Because manufacturers make them and people just accept it?
I am sick of hearing about phones weights differences in few grams, (our phone is thinner by 1 mm!!! -how sad) , about screens quality, about processors speeds, etc, and on.. Just because this is where all attention is?
What is use of it all if then users have to carry chargers wherever they go, they have to disable network modes, tweak performance, buy and run monitoring softwear, a lots of hassle JUST BECAUSE those manufacturers are jerks! Like there is problem to give proper large battery option to chose and we will see how market reacts?
I got phone from China with larger battery than you can get on any European market and I am finally happy, I don't worry about anything anymore.
On purpose I set everything to look nice, bright, run fast and never worry about any tweaks unless I suspect unhappiness from performance being somehow compromised, I do play games, I do use internet, I do stream and do other things without fear of not having more power for a call I may need to make. At end of day I have still 50% which will last next day easily.
BATTERY IS CRUCIAL PART OF THE PHONE. MUST NOT BE REDUCED IN PERFORMANCE IN ANY WAY (reducing size).
This is why we have smartphones to do many things quickly at any time instead switch all those cool features off, like everyday life was emergency situation for saving battery -ON DAILY BASIS?
P.S. some brands thinks I will carry second battery with me like I have a pocket and good will to open my phone and swap batteries??? really??? or taking ugly external USB-battery, swinging on cable while I am using my phone or looking ugly like second half of nadset to damage my USB socket with a time and have a patience to keep it charged -like a second device?
How ridiculous...
No matter how big batteries are, they will ALWAYS fall short for some people. There is no way around it.
The stock batteries in most phones are good enough for average users. You're not one and that's okay - but that's why there are choices.
The SG3 stock battery lasts me the day about 6/7 times - I only feel pinched the day I have a large break and might want to watch video or play games for an extended period of time.
I had options. I could have gotten an extended battery - no swapping, just bigger phone just like you clamp to want. This is available without having to get a phone that may not have good developer support.
You deride external chargers and spares, but you need to chill and realise that different people have different needs and that's why choice is good.
I like having spares. Opening my phone up and changing takes only seconds and I can them in my pocket or bag and I can charge a battery while using a different one. I hardly ever plug the phone itself in any more.
External chargers can power multiple devices and have HUGE capacities compared to even very large extended batteries.
There are so many choices at I don't tnk this is a big/any issue. No battery will be big enough for everyone unless perhaps the technology is completely revolutionised beyond what it is capable of today.
So yeah. Battery issue is not an issue.

Putting in larger batteries makes the phone in turn bigger and heavier.
That's why they probably limit it as people prefer thinner and lighter phones!

LIFE!
IT'S WHAT YOU MAKE OUT OF IT!
I'm satisfied with the battery life of my s3. I take it for granted that i need to use a charger if i continouisly use it. I wouldn't want my device to be even bigger, left alone to weigh anymore than it does already....
Frankly, if the average (read: majority) user had such a problem with battery life more companies would invest a lot more on battery research.
I could've used a more battery friendly ROM on my phone and have it last days on my 1700mAh battery, but I don't bother because at the end of most days I'm left with something above 20%.
I have three spares I never use plus the three year old stock battery, and I've not really ever needed them.
I'm also not really a big fan of "perfection", which for example is why I'm not an iOS user.
Perfection is synonymous with boring in the tech world, and battery constraints actually demands something from the phone designers.
That demand holds more value than most can imagine.

New technology has higher power requirements. It's not fair to compare phones today to one's from 15 years ago - I mean, dude, back then it's not like you were doing anything other than calls on that thing - certainly no streaming or anything.

I just bought a 58WH portable power http://www.mrbattery.com.tw/product_detail.php?pid=MBP0001023
It's able to let my brightness100% and CPU stick on 1.6GHz for 3 days and nights!
I own a HTC Desire hd previously. That phone battery life was totally horrible. I had to carry a portable charger everywhere. In comparison, s3's battery life is beyond excellent. (Note: I disabled most of the power drawing apps/functions.)
With that being said, having a large capacity battery is one of the main thing I look out for when buying a phone.

We're kind of at the end of the rope concerning battery capacity. There are just no easy ways to store a lot of energy in a small place. If we were able to build batteries with higher capacities in reasonable formats, we would already have them. Every new advance in battery technology only adds a small percentage of capacity or lengthens its usable service life somewhat.
But I do agree that the phones are now at a comfortable size, battery life should not be sacrificed for thinner phones. I bought the extended battery for my S II, it only makes the phone a 3 mm thicker, but that does add 20% of battery life. IMO they should have released the phone like that, but then they would have not been able to market it as the thinnest phone.
Know your battery & maximize it [Lithium-Ion]
I understand each has it's own way of fighting this never-ending battle, since battery is something we can never have enough of. It's always good to squeeze an hour more or prolong the healthy live of a battery as much as possible. Some are lucky to have removable battery so we can replace it with ease, while others with uni-body design smartphones are pretty much stuck (unless you wanna spend some relatively big bucks) with the one their phone came with. So maintaining it is quite important.
"There is no black and white in the battery field, only many shades of gray. The battery behaves much like us folks — it’s a black box with a mind and mood of its own; it’s mystical and unexplainable. For some users, the battery causes no problems at all; for others it’s nothing but a problem."
Isidor Bauchmann
Anyways, let me share you my way of taking care of a battery and my settings that I use to extend battery life as much as possible (my Screen on Time SS bellow). Again, it is the way i use, operate. It's far from perfect.
Disclaimer: I am not an expert on batteries nor Android, it's simply knowledge/info what I gathered through my time with Android smartphones. Everything I know I read somewhere (article on net or post right here on XDA or some other forum.) Nothing you'll see here is my credit!
First I'm going to cover maintenance (charging), then my software setup, and lastly a way of "calibrating" a battery.
1. MAINTAINING Li-Ion battery
Let me just say there are many theories out there about how to maintain a battery. I've seen many times that you should charge the to max (100%) and discharge them to min (0%) as batteries have so called "memory", thus you wan't to fully charge&discharge so that battery doesn't get "lazy" or rigid. This is just wrong. Misconceptions like that are very common! Some guy even said it was written in product manual when he bought a video camera back in 2005. Guess that Canon just printed "common" knowledge back in 2005.
The fact is, batteries are prone to age due to corrosion! We can influence that ageing with proper care...
The fact is that you should keep your battery state between 20-80%... Charging your battery to 100% and discharging it to 0% is considered stressful for the battery. Also, fast-charging is not the best way of charging. Pushing higher voltage is also more stressful for the battery and chemical reactions within, than charging it with lower voltage. Yes, "fast-charge" with higher voltage will speed up the Stage 1 of a charge and reach 70% of a charge quicker, but Stage 2 - saturation charge will take longer. If you are in a hurry and need some juice, that's good and comes in handy. New devices like Note4, Nexus6 and others promote fast-charge and brag how fast can you charge your phone to 70% (like just in 35 minutes you'll reach 70%). You might notice that in-fact phone says 70% when you unplug your phone from the charger, but battery will probably also drop faster than normal. That is because Stage 1 was complete in a very short time, but Stage 2 (saturation charge) never kicked in.
But as said, full charge is not even preferable for Li-Ion based batteries. I'd say you should make a full charge when you know your day will be long. But if possible, on a daily basis you should keep the battery level from 20-80%. That way you won't put battery through much stress and prolong overall battery life. Also, using a lower amped/voltage charging is preferable. I often charge my phone with computer via USB cable. It takes 4 hours or even more to charge my Note 3, but this way it is way less stressful for the battery. Some battery manufacturers intentionally limit chargers to stop charging after Stage1, to prolong overall battery life.
Also, when battery is charging it heats up and battery gets agitated so battery readings can be a little off. It needs to cool down so it reaches equilibrium and battery readings will be accurate again. This might sometimes explain why battery seems to unreasonably drop and after some light usage it stays on certain percentage or drop with normal rate... (battery level readings can be accurate to certain extent....)
So to sum up: slow charge and keeping battery percentage off of extremes are 2 things your battery will appreciate...
Also, temperature is also an enemy. We'll get to that in 2nd topic below.
2. MY SOFTWARE/HARDWARE Setup
First of all, a base for a good battery life is good ROM and battery efficient kernel. If those are bad, you'll have hard time (maybe even impossible) to reach a good run. I happen to use @temasek ROM & kernel that happen to be very battery efficient.
If you are root, you should take that advantage and install some apps that will help you with battery life.
I (and many others...) use these:
- wakelock detector
- faux clock ,
- Battery Stats plus,
- and Better battery Stats for keeping an eye on apps that eat your battery the most.
You can use wakelock detector to see if there is any app that is preventing your phone to go to deep sleep thus draining your battery by keeping CPU at a higher rate. If you have a wakelock blocker built in your ROM great, if not you can try wakelock terminator. I haven't tried it as it is a built-in function in Temasek's ROM. Also, i think i shouldn't be even mentioning how much of a battery hog a display is. Keep your brightness as low as possible, turn Wi-Fi on when you need it as well as data connection, GPS and NFC. I only turn those on when needed.
There's also well known myth about clearing Recent's from RAM. Don't do that. Re-loading apps from storage to RAM over and over again is time & electricity (battery) consuming. Keep those apps in RAM, Android does hell of a good job managing it. It's not like Windows environment (or any OS for devices with unlimited electrical supply - not battery driven). Good cellphone reception is also worth mentioning. Avoid areas with low reception as phone tends to constantly search for new cell towers with better receptions - huge battery hog.
The second one is a kernel tweaker. There are plenty out there. I use this one (a good purchase, one of the best i've done) as it has a ton of options. I think the best way of sharing my settings is via Screen Shots. They are attached below.
Sure there are plenty of options to tailor to your needs. Choosing a suitable governor for your needs is essential, however there are some settings i (and many others) would advise you to stick to.
CPU Hotplug intelliplug (instead of stock MPDecison)
Intellithermal Thermall manager (instead of stock one) + lowering Temperature as seen in SS below
Battery Throtling with values seen in SS below
Here is where you can limit your battery to reach higher temperatures than healthy level. If your battery gets too hot while charging (or use) you should unplug the charger (or discontinue heavy task). Not only for the sake of battery but phone overall...
There are other apps that prolong (or at least say that they do) like Greenefy (probably the most efficient one, and loved one by most users), battery saver and others..... I do not use those.
Edit:
3. "CALIBRATING" BATTERY
I put that in quotation marks as it is not (at least i haven't found) scientifically confirmed. However, from time to time i tend to preform this treatment... As stated before, fully charging&discharging is not the top-best treatment for batteries. It lasts longer in a short term but shortens it's healthy life in long term. But from time to time i do put my battery to this stressful cycle. It could be a placebo effect not really helping at all... Even more, as stated above, fully charging and discharging is not advised because it puts battery through a lot of stress!
Drain the battery complitely flat (phone shuts itself down)
Put your AC cord in and let it charge for arround 3 hours while phone is OFF
Unplug and turn your phone ON
Let it rest for some half an hours (don't use it, you don't want to put too much stress to battery))
Put AC kable back in and charge it for another 30 minutes or so
"Super-charging" your phone like that ought to calibrate your battery. This shouldn't be done on a regular basis as you put your battery level to extreme thus stressing it.... As said, it is unconfirmed method but i tend to do it from time to time (once every 2 months).
Again, this is something that has not been tested. It might be a placebo or smth. However, here is the source: http://forums.androidcentral.com/htc-one-s/174458-how-calibrate-battery.html
This method is for nickel cadmium batteries who suffer memory effect. Thanks to reddit user r/Saicotic for informing about my misinformation.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
This is it. This is what i've learned about batteries and how i do it. It is by no means a perfect set-up! Please let me know if you know about a better set-up (kernel tweaks), any good app or any other info on how to extend battery life.... Please let me (us) know.

Also, fast-charging is not the best way of charging. Pushing higher voltage is also more stressful for the battery and chemical reactions within, than charging it with lower voltage. Yes, "fast-charge" with higher voltage will speed up the Stage 1 of a charge and reach 70% of a charge quicker, but Stage 2 - saturation charge will take longer. If you are in a hurry and need some juice, that's good and comes in handy. New devices like Note4, Nexus6 and others promote fast-charge and brag how fast can you charge your phone to 70% (like just in 35 minutes you'll reach 70%). You might notice that in-fact phone says 70% when you unplug your phone from the charger, but battery will probably also drop faster than normal. That is because Stage 1 was complete in a very short time, but Stage 2 (saturation charge) never kicked in.

Actually, this point is currently in contention among material scientists.
I think most li-ion cells in mobile devices are probably geared toward 1.2A or higher. Charging via USB at 0.5A is probably detrimental in the way Chueh et al describe. I agree fast-charging to top-off battery is probably suboptimal due to heat generation, but I'm current students indicate fast-charging at reasonable temperatures is better than slow-charging in general. Slow-charging does yield greater charge saturation, which is the most likely contributor to lithium salt precipitation.
Fast charging at 2.4A probably isn't too bad, as long as you keep temperatures reasonable. The only reason you shouldn't top off at 2.4A is because your battery will saturate but will continue charging due to voltage delay. Thus, heat is generated as a direct result of excess charge (inherent to li-ion). However, modern fast-charging adapters and devices will reduce current when the battery nears full saturation. It's possible that devices using hacked fast-charging don't realize attenuation and thus unexpectedly shorten battery lifespan.
I use Amplify (xposed module) which I can recommend.

Phone had a restart, if you did not do anything on your own.
I heard many rumors about Li-ion batteries but my habit is to charge to 100%, im willing to keep this phone for year or two, will i notice big changes?
and are these rumors true? im usually charging phone from 20-30% percent to 100% once a day or maybe once in two day depending usage (but once in two day happens very very rare)
If rumors are true:
Rumors suggest that optimal variant is to keep it 40-80%, but if i charge it to 90% (to reset stats), will it be a problem?
Thanks in advanced

In my opinion, there is no problem!
The only thing I know it is really bad for battery is high temperature. Avoid quick charge at all costs. The slower you charge your battery, more battery life you have (long term).

yea, fast charging only when im in hurry, otherwise i dont see any need for that feature.
Well im worried of that 40-80 tho, its kinda like emptiness when i unplug on 80 rly dont like messed battery stats and so on... but if the rumors are true then im gonna ask if i can charge to 90 to reset stats... if not then im gonna say NO to my habits and....

There are so many misconceptions about batteries! Everyone will say something different, so use the phone the way you want and enjoy it.
The truth is that a lot of the so-called "claims" about best practices have not been proven (hence why there's so much misunderstanding). Yes, high heat can indeed be bad for batteries, but there hasn't been much proven as to how much quick charge will take out of long-term battery life. Same goes for the "charge to 80% theory" - if you keep that mindset you'll always have less battery life than someone who charges to 100% (20% power - give or take depending on the accuracy of the battery meter is a lot, and probably far more than most people will see in a year. By then, you'll still have used up more charge cycles and your battery capacity will be less than when you first got the phone.
Basically, what I'm saying is that there probably isn't a lot that can be done to significantly improve the battery longevity over time. Sure, there are some ideas on "best practices" but just how much difference is it going to make?

well, most fearing part is that this claim has been given by Battery University.
Yeah, we cannot prolong battery life forever, but im not keeping phone forever either, i want to get best results around about year or two, so my goal is to save battery as long as i can, no matter of cost or "No" to habits... so what you think, charging all time to 20-30->100% will not change situation that much about 1-2 years?

dude, just charge it whenever you want and that's it, why complicating ? My gf's lg g2 has same battery life for 3 years, and I can tell you she doesn't give a f*** when and at what percentage she will charge him. peace

exactly that it is... they said that charging like that will preserve battery longevity and always charging to 100% will degrade it so it means ur gf does it right?
exactly that is my concern, i love to charge it 100% always...
