So I fell alseep on the couch and woke up to a thunderstorm at 4am in the morning . Now that I am unable to sleep a idea slams into me like an 18 wheeler . Its a known fact one of the issues surrounding smartphones this day and age is battery life or lack there of . From the earlier beginings flip phones had a battery life of several days , bare in mind these phones just did basic text and calls . But none the less end users got used to long battery life of a phone . Now to the brain storm . What if the approach manufacturers are taking is incorrect ? Every smart phone I see on the market has a battery that is inserted into the phone and then a cover or back plate is then applied . With Motorola's Razr they have proved a thin phone is possible using a battery designed similar to the iphone . Question and proposed Idea , Why not use the tech used in the razor to create a super thin phone but , make the connector to the battery similar to say a plug in and receptical but in fixed locations . What Im driving at is make the battery cover "the battery" that litterally snaps onto the phone. Yes you will increase thickness of the phone slightly but the area a normal battery cover takes should more than increase the size of the battery past the 1750mah mark quite easily . The only downside to this brainstorm is either battery backs would become generic or price of phones would skyrocket due to the battery back being different for so many phone . Anyone elses thoughts or ideas on this ?
Interesting brainstorm... My old LG EnV2 was like that and it's battery lasted a couple of days lol
you know they keep making these phones thinner and I have been saying for a while that I wished they would use the smaller technology to make room for a bigger battery .
I don't need a 3mm thick phone but a smart phone that does not require daily charging would be great .
Love the idea and Motorola is heading in the right direction , but in talking with friends with iphones, they do the same as i do....charge the phone when they go to bed and take it off when they wake up....I think the best result would be for manufacturers to work on their kernels and how the processors work instead of worrying who can put the most RAM or the fastest processor or the most features into their phone.I can agree with what you say about the old phones ,my backup phone is a Samsung ultra touch and it lasts for 3 days without a charge

I would love more battery life, but..I don't get the people that hate to charge daily. Where the heck are you people sleeping that doesn't have electricity?!?

This. Plus the battery would block the antenna rf and reduce surface area for placing it elsewhere. A lot of the phones shove antennas in that cover. Oddly not the 3D which could be the reason our reception is generally bad.

From a design perspective I dont think this would be an issue . Iphones place the antenna on the outter edge of the phone itself. so making the back of the phone a battery itself shouldnt interfer with the antennas in this configuration

in a sence this is what the brainstorm is about . The phone itself would already be made ultra thin (example Moto Razr) the back being made of a battery would only increase the thickness of the phone by say the typical thickness of our current battery (example) . From a design and engineering standpoint I dont see why this route hasnt been taken as of yet .

I think it comes from my previous example of life with flip phones . I can relate personally when I had an EVO 4G with the 3500mah battery . To have a smartphone you never worry about plugging in is a freedom that is hard to explain . I feel the best way to put this is , remember when fuel was only 1.29 a gallon and then prices inched up alittle . People didnt like it raised hell about it but in the end people just accepted it .This cycle continued till we are at the current price of fuel 3.09-to whatever . The cycle is only reflected once again here in the smartphone world. We were used to phones that lasted days , then phones advanced , ok they last a day now we accepted that . Some cases phones dont last a day we accept that and move on . I guess what Im trying to say is we keep accepting it for what it is when there really should be no reason to accept that situation with phones .
Additional thought , Example Samsung Galaxy S 4G touch , The phone is ridiculously thin . What if the whole back of the phone was a battery(except the location of the camera etc etc) . The phone itself is a monster with its size . The surface area of the back of that phone with a battery back the thickness of say our current battery , you know it would easily be over a 2000mah battery . Phones are already progressing to being wider and bigger (to me almost on the verge or being micro tablets) they are already big in a sense . Adding two millimeters thickness to the back of it is not gonna make the phone that much thicker in relation to an already super thin phone (SGS2)

Friend of mine has an iPhone, the case is the battery.
Its not the size of the battery, its the technology in the battery. I wish someone would engineer a compacitor to replace the whole setup. That way we could charge up almost instantly and use our phone for hours.

Ive been saying it for a while now....Nothing with batteries will change until the tech behind it does...I think weve milked lithium ion for all its worth , time for a change...
I'm surprised that no one posted this in this thread, but it looks like Lithium ion batteries might be around a bit longer:

Nowhere, I bought a solar charger/battery from One Sale A day for $5. LOL, works pretty well and the whole unit is only about 3/4 the size of the evo 3d battery.
changed my 3.8 battery for a 3.7 and now I dont have the charging/quick drain issues anymore
but my rezound still gets HOT and pretty quick too
anyone have any fixes or ideas?
I'm running an ICS rom...Jolez ICS Sense Redefined-Always Brilliant!

Well first off, what are you doing to get the phone hot? Or is the phone just getting hot sitting idle?
how hot and what are you doing like said before... phones get hot its just normal...
it does not get hot at idle just when I am browsing internet or navigaton or viewing videos

Well alright then. How hot does your phone get when doing this, temperature wise?
Your device is defective. Had similar issues. Spoke to htc tech a.d confirmed. I used to run temps in the 120's doing simple apps . New unit is great and cool on most uses. Battery life has doubled too.

Good to know. I can never charge my phone with 4g turned on for more than 10 minutes. It always starts blinking. It would suck to say that my phone is defective. I keep waiting for a fix, but I might have to call this one in and get a new one.
Where does this 3.8 vs 3.7 rumor originate from? I have a 3.8v and have had ZERO issues with heat, what defines hot? Physical heat or CPU/Battery temp?

I agree, every phone I've had has gotten to highest temps using GPS. Its just part of computers, everything gets hot after high usage, its normal. If your phone gets too hot, it'll shut down like a computer would or a rezound OC'd.

Yeah, thats not a rumor. Do a search for 3.8v and see all the posts that have been over this. 3.8 has major issues with heat, if yours doesn't consider yourself one of the lucky ones. Also if you do root, stick with the GB roms. ICS roms have problems with charging past the high 80's for battery capacity.

Heat
When I called Verizon to see what they could do about my Rezound running hottish (gets to 110 after running Sentinel 3; around 113 in navigation; idles in the 70's), I was told that Verizon and HTC have never heard of these phones getting hot, or heat being an issue, but they had helpful hints:
1) If you are streaming, stop streaming for a while
2) Put on a Vinyl case
3) Buy an extended battery
4) Hard reset
5) Realize it is a computer without a fan, it will get hot
So there you have it. Per Verizon, they don't get hot so your initial premise is apparently wrong. jk.
I tested 2 refurbs. First one shot up to 130 almost instantly, and that's when I learned what real heat was. Second one mirrored my current Rezound # 4; idled hotter on side by side, but temperature increased less when running the same apps. Decided to return both refurbs and keep my current.
not sure about anyone else but Just got my GS3 from sprint and turn on to activate n is working fine but the phone is getting hot. Any calibration need it? plus I'm not feeling the physical home button.
I still wish it had a dedicated camera button. I was once an iPhone owner... so the home button doesn't bother.
Mine gets warm, obviously more-so when charging. But nothing alarming yet.

thats funny because the snapdragon s4 chip was made to not get as hot as the older s3 chips did. my old SII got up to 107 to 110. the hottest ive seen this phone is 95. my old galaxy nexus was the worst. it got HOT 140's at times. this phone doesnt get any where over 95... so... there u have it... its nothing to be alarmed about. this is actually an improved product.
I found the phone got pretty warm when I used it without having the power savings on (found in settings).
Once I turned that on it nearly doesn't get as warm as it did. I'm not sure if anyone else noticed that or not.

Good for you.
at least its not as bad as the iphone trust me haha that thing is bad!
Got up to 119F today, stupid hot day though. Extreme conditions, on my dash car dock. Normal usage is around 92F.
Casing definitely transfers heat well. My old Mt4G had the metal back and even at hotter temps you could barely physically feel it. Being thinner too probably doesn't help.

Mine gets warm, but not hot. My iphone used to get really warm where it would shut off, this has yet to get anywhere near that.
keep in mind that the S3 is a powerhouse phone. the S3 can match the processing power of some low end computers, and think about it.. those low end computers have a large fan. I would get a task manager and as long as your phone isnt constantly above 110 or maybe even 105 you should have nothing to worry about.

The battery?
---------- Post added at 01:32 PM ---------- Previous post was at 01:26 PM ----------
Ok lol I thought 105.3 on the battery was hot, but glad to see its not just me. its funny how with all these advancements in mobile gpu technology I still don't think it out performs my intel hd 3000 integrated graphics. Thanks to the android x86 I was able to run antutu on my intel core i5 2450m @2.5 ghz and scored a 21000. I highly doubt it was accurate as Im sure it isn't optomized and it fails to make use of turbo boost. Given this isn't a low end computer, but I still don't think we are that close. Apparently the new ipad's gpu is 30 percent slower then the on in the wii.
Can anybody explain to me why all of the sudden my battery life has sucked. I have had WolfROM for about two weeks and battery life was normal. Then around 3 days ago my battery just won't last. I don't know what the deal is. I did spend the week in the mountains of Georgia where it was constantly searching for service so it got really hot. I assume that is what killed it?

I would expect it to. In your particular situation, the easiest route to an answer is to put it in airplane mode for several hours and compare.
Also, if it really bugs you, get one of the apps the other guys have suggested.
Although it seems to happen less frequently, sometimes an app update keeps the phone awake.

Alright thanks for the info, I'm gonna try this out and see if it works. im gonna get betterbatterystats and see if anything is keeping my phone from going into deep sleep and if that doesn't work ill put it in airplane mode so as to compare the battery life with what I get now.

On mine the download manager was using as much power through wake locks as the screen was. Disabled that ***** and turned off force gpu rendering in the developer options for good measure. It made all the difference.
My phone was over heating and losing charge extremely fast. I decided to try something random and put some of the aluminum off the back of a laptop LCD between the phone and the battery. It seems to keep the phone much cooler and the charge holds a lot longer. I can play Finaly Fantasy 3 now for a few hours without the phone getting hot anymore. Don't know if it will work for everyone but it seems to be working for me.

They wanted me to let them replace mine, but I told them to **** off. I'm not giving them a new phone for a refurb. That is one thing they could definitely use some improvement on. If you sell me a faulty device don't try to give me a refurb, give me a new phone.

Nah, the battery can breath fine. The insulating aluminum is actually between the physical phone (sim card and all the interals) and the battery. The battery is completely open on the back. The phone itself is also not getting hot anymore so I don't really know. It used to get so hot that the screen itself was hot to the touch and so was the plastic cover on the back. The battery actually has the paint missing in the pattern of the lines of the rear cover from being so hot. I am sure the battery is at least partially cooked but it made it a full 12 hours today on one charge, thats up from 4 hours.

Results are skewed for the day, I pulled the battery to replace the aluminum. I didn't have any scissors yesterday so I wound up with a rough looking piece of aluminum that I had to tear apart to make fit. I cut it to fit today so its a much nicer fit and it still has some adhesive from where they glued it to the monitor. I'll let it burn down all day tomorrow and post the stats. I had wifi and google maps running evidently though during that time. I know I talked for around an hour and a half on it and I was in the office most of the day with nothing to do so I probably spent two hours texting.

I had only been on WolfROM for a week. My battery seems to be returning to normal though. I guess some normal usage fixed it.
jus got my s4 yesterday.. great phone! but I'm noticing that just doing normal stuff really heats her up. my s3 heated up as well, and it was on the bottom of the phone making it uncomfortable. but the s4 gets warm, or hot, on top. the ear piece gets hot and so does the camera area. I presume this is where the antennas are?
anyway how's everyone else's? good thing I don't talk on the phone often because if that thing heat up my ear I'd return this phone asap lol

It may be your service area. In places where theres low or spotty service or a fringe from 3g to 4g, the radio has to work harder, thus heating up.

Mine gets hot/warm doing normal crap too.. kind of a bummer because the Note2 doesn't get this hot.. just warm at times. I'm assuming this is where the CPU is located, near the center top area where it gets warm/hot.
It's something about Qualcomm it seems.. all of their CPUs love to heat up fast.. seems like the battery percents also drop fast whenever it warms up.
funny thing is that my DNA never gets hot, and that's the snapdragon quad core. and hwen it gets warm, it never breaks 40 degrees C.
the gs4 easily hits up to like 37, 38 degrees C....but even when my DNA is that hot, it doesn't feel that hot. the heat dissipation in that must just be better than how samsungs is. kinda worries me, but my gs3 was just as hot.
i put ktoonz kernel in, which seems to not have the CPU running at full speeds like the stock kernel does, so i think that may be helping. i might flash a custom rom next.
I'm stock rooted so I can't say for other roms/kernels. Mine doesn't break 35c which is a miracle to me coming from the heat plagued rezound where 45c can be achieved just browsing xda for 20 mins. I didn't like how hot samsungs 2amp charger makes the s4 whole charging (even during idle about 35c) so I use my htc charger which is the same 5v but only 1amp. Charges slower but will increase overall life of the battery

and yeah the rezound was a heater lol i had one.
I know I remember seeing you over there. nice to see some familiar people here. That's on 4g outside yesterday 90 degrees outside Internet browsing and some YouTube for an hour straight. The hottest ive seen was 42 but that was in my car with the sun beating on my pocket with the phone in it.

The only time mine ever got hot is when I used a sleep tracking app which required the phone be on all through the night. Being under my pillow probably didn't help either, but it the battery temperature apparently got up to 45 degrees celsius which made the phone stop charging too.
good to know it stops charging at 45...the rezound didn't lol.
mine right now is sitting at 33.6 degrees C. i'm copying like 6 gigs of music to my sd card. thing is, the earpiece and camera are very warm..the entire top of the phone. can't imagine how annoying that must be when you're talking on the phone...good thing i never make phone calls :\ lol
if you look in system panel or something, you can see that all 4 cores are like always working....and the CPU speed is hardly EVER below 700mhz when the screen is on..i find that odd. my DNA would easily hit down to like 300. it seems like the s4 cpu is always doing something..it's always above 50% on mine, never below. i find that pretty odd...bc idk what it's doing in the background. i put on ktoonz new kernel and it helps a bit, but it's still running often.

god i'm really hoping there isn't a bad batch of ones that get hot. i went through 3 at the store to pick the right one...two of them actually had banding issues on the screen....SERIOUSLY?! i thought we were past that on AMOLED?!?!
they ALL have this very faint veritcal line towards the bottom that's like white when you're looking on a gray background.....every single S4 i've seen. it's crazy. idk wtf it is. this one had it, but the least amount compared to the other 2, but i think i have a tiny piece of dust under my screen. is it really that hard to ask for a piece of technology that's perfect anymore? lol
Do you have power saving mode enabled? I do and trickstermod shows it rarely using anything above 1.3ghz which I like very much lol. Im guessing the gpu and cpu is up in the camera region as it only gets warm on mine when watching videos or having the screen on for long periods.

Holy crap I was tethering using my S4 and charging it up at the same time.. It felt dangerously hot.. I sure hot this doesn't fry the phone, i'm pretty shocked there's not a safety circuit that turns off charging when it gets this hot. This worries me as I rely on tethering for work pretty much daily.. it did seem like once it charged to 100% the heat level went down a bit.
My Note2 gets warmish when tethering and charging.. no where near the heat level of the S4.

next time you do it, check the temp with an app like system panel and report back how hot it was.

If you have a different charger, use that one Samsung gives us a 2amp charger out of the box which is nice for fast charging but is going to cause shorter overall life of the battery and hotter temps. I use my htc charger and it keeps it much cooler, especially when using it while charging

I haven't noticed any heat problems thus far. Sometimes the back under the camera gets a little warm but nothing out of hand
It runs cooler than my gnex!
Gnex and s3 always ran hot for me when torrenting or gaming. My note 2 didn't have this issue. Well because it was probably huge. And now s4 issue remains. Maybe the size of the phone? It always gets warm where the cpu sits on the board. Not a huge deal. I never let mine get scolding hot. But it'll get warm.
