Galaxy S - battery endurance WRT user / provider profiles. - Galaxy S I9000 General

First off, apologies if this is a dupe, I did search before posting and saw nothing on this precisely.
Please read ALL this post before jumping to conclusions as the first bit may sound like an advert, it isn't, it is just setting out the background facts.
I have been reading these forums quite extensively, and last week purchased a new Samsung Galaxy S, on the Three network here in the UK.
I *was* looking at a Google/Samsung Nexus S, but last week the swingeing data allowance cuts hit, and basically everyone in the UK was cut to 500 megabytes a month.
My phone is on contract with Three.co.uk, the package is called "The one plan 2011"
For £35 a month I get 2,000 UK voice minutes any network any time, 5,000 3-to-3 UK minutes, 5,000 UK texts and "all-you-can-eat" data.
Three in the UK is fairly unique in that they have their own infrastructure / towers etc, which is probably why the can provide unlimited data.
The Galaxy S itself is I9000NEJP2 kernel 2.6.32.9 build froyo.nejp5, Kies did one firmware update the day I first got it.
Since then I have rooted it with z4root and applied OCLF.
Wifi set to cut off with screen, pure black background wallpaper, lots of GPS / navigation / wifi tools apps installed, push gmail.
No games installed, I do not use it like most people, I specifically bought it because it is essentially a super-portable mini linux computer with a vast array of connectivity features and many wildly useful android apps.
I would describe it as a tool, something I use.
Battery life is basically more or less as expected, last charged late last night, currently at 11:14 am showing 78% remaining charge.
I have a car charger for when using it in the car, I have a home charger for when using it at home, and of course it will pull some charge through USB when connected to the laptop that I am typing this on.
Of course the 1,500 mAh battery is replaceable too.
Basically battery endurance is what I expected, I fully expected to be able to flatten the battery in an hour or two by turning everything up to max, turning on all the candy, installing dozens of useless apps, and playing games and videos...
I am old enough to remember running ghetto blasters that took 10 x Duracell "D" cells that could be used up in as little as an hour if you whacked the volume and bass up...
The laptop I am typing this one is good for maybe two hours away from a charger if I hammer it playing crysis on full brightness etc.
So, the purpose of this post.
I have spent many years working on and with power consumption of computing devices, and by far the worst metric you could use when trying to chase something that was eating all the power was user feedback... no two users reported the same thing, not even on the same hardware.
power measuring devices also were pretty useless unless you could point them at individual components rather than a system as a whole.
I have solid 3g reception from Three, and when on wifi the router is in plain sight around 4 metres away, on a channel that no-one else nearby is using, which means that the wireless portion of *my* Galaxy S in *my* location doesn't have to work very hard at all, which means it doesn't draw much power.
Yes, it is a "smartphone", and there is no point buying a smartphone if you have to dumb it down to dumbphone levels to get it to run for more than an hour.
On the other hand, nobody said it could have everything turned up to 11 and it would last for 300 hours.
My heart goes out to INDEPENDENT (not samsung etc) developers and coders..
1/ they lack a suitable test suite that measures consumption by each circuit over time, so that they can determine the effects of code changes on power consumption.
2/ they lack empirical hard data on 2g/3g/2ifi signal strength for a wide variety of users.
3/ they lack an accurate users profile of many users, the old joke about cutting the arms off an italian makes then unable to speak, take the battery out of a modern phone and young people are zombies.
So, the REAL purpose of this post
Can I suggest (I can't code, not even to save my life) that development of apk's to record the above three items, which will give developers hard empirical data, would be a useful first step.
I have a contract with 3, provided I still get what I pay for, unlimited data so I can tether my laptop and access servers etc, I really don't give a **** about Kies / Samsung updates, I'm quite happy to wait until 2.3 is out for the Galaxy in these forums and upgrade what I see as my portable mini linux star trek computer myself, it will still work with my provider...
I myself would have no problems whatsoever volunteering myself, and the obviously increased power consumption of background monitoring apps, and any data so collected, for the common good.
If we could get a couple of hundred other to agree to this, then it becomes worthwhile for someone who can code to write these apk's, and the whole community benefits.
cheers

MESSAGE to HTC, Tmobile, Android and Google

There is a problem with our battery life and we all know its true... I have even been given a new battery and HTC mains charger
I turn off any service im not using at the time (ie: wifi, BT, GPS, NETGPS,etc) not that I should have to do this, but lets story on track...
My battery will make about 1 day as I am A "power user" but if its not plugged in I wont have the juice for my alarm to wake me up, my wifes Sony Ericsson lasts 4-5 days per charge, but lets not compare apples and oranges, the whi-phone 3g my sister has sahe bought it about the same times as my g1, she hadn't ever heard of "deep cycling" 2-5 times when you get a new phone, she never lets it discharge fully and just tops off all the time, AFAIK she is treating a NIMH cell exactly the wrong way, BUT SHE GETS 1-3 DAYS depending on the type of use, and never turns off ANY of the 3g, gps, net gps, wifi, BT nada and Id say she uses hers alot because its her primary camera, GPS & A/V player
my question is WHY?
Im sure there must be somebody involved with the development of this phone/OS that reads thru here, since there is more exciting stuff coming from XDA than there is the market...
Im gonna add a poll that pertains to battery use...
I wanted to add one very negative one but hit submit not preview, maybe just post and dont vote if none apply..
they better come off a new battery almost all other new phones will get 1-2 day + average use, Ive had phones that could go 3-4. but the state of the art G1 mindblowing innovative phone wont even work a whole day, so what if its bigger than the whi-phone, it has no keyboard.
I for one would like to hear some solid info on a replacement battery and back, for new and existing G1 users, early adopters got the fuzzy end of the lollipop on the HTC->headphone jack adapter I got the headphones with the htc angled adapter from fleabay, so many manufactures stick it to the early adopter, when we are the ones that get the word of mouth going, as people go "WOW that thing is cool!,what is it?! they know when we bought out phones and should be able to figure out when the head phone rev change was made, so send them to the first of the buyers....
IF the battery issue isnt fixed, alot of people will be very angry and the g1 will flop.
I think the bad press is starting to out weigh the good press the G1 and possibly android as a whole is at a crossroad. If the g1 tanks Android will be stained forever...thankfully enuff I dont think XDA-DEV would give up on this badboy, I love this thing, and I love it for what it can be
BhanG
Well stated sir.
HTC/Google need to fix battery problems in G1. Maybe it's soft bug, but maybe it's a hardware bug - Nobody knows
I dunno. With normal use, I get about 12 hours or more from my stock battery. That's about the same as other HTC phones I've had.
there is a battery issue and we are al aware of it.
i have managed to have it last through out the day
just set the brightness to the lowest possible, sleep time to 15 secs
turn off data and wifi and anything else that you are not using
its not how the phone was intended to be used, but it's what i ave to do for now
I find it fine for everyday use. Of course I haven't done a full test but maybe tomorrow I will.
I would like to use my G1 like I use my WinMo but no way I can with the battery.

I think you're exaggerating here a little bit. The battery life, while it got press at first, has faded from the limelight of android news for the general population. The G1 is already far from a flop and I don’t think there’s going to be a sudden mass return of all the handsets sold.
Let’s face it living on the cutting edge means you will get cut sometimes. Your high expectations will not always be met and manufacturers will frequently not care. The battery life is less than what many people expected, but we’ve learned to deal with it. At least we have options (power management, backup batteries, and expanded capacity batteries), but I’d not hold my breath on HTC making any major moves. How long has the issue been going with the TYTN II drivers anyway?

I have no idea what kind of use gets 1-3 days, but it certainly isn't 3G web browsing. Most iPhone 3G battery life tests clock 3G data use at about 3-5 hours. Based on my own usage of a friend's iPhone 3G, that seems to be about right. Coincidentally my G1 gets about 3-5 hours of 3G data use as well.
Frankly, from an engineer's point of view I have not seen any power drain tests conducted with enough rigor and variable control to be worthy of being called a truly scientific analysis. Even the best "battery life tests" out there aren't declaring what type of testing environment (los and distance to closest 3G tower), what background apps are installed, ambient temperature (which affects the battery discharge profile), etc. Without considering and removing these variables from the test, deviation could be as high as... well there's no fixing the percentage really. It's all just junk data.
I do notice after I installed Task Manager, to close out programs I am not using my battery life went up. There are a lot of un needed start up apps.

Yep my friend has iphone and we did test last weekend, both went 3 hours and change then died. If i dont use internet and set timeout and brightness down plus use task manager mine will go as long as my dash. I personally dont care about the battery life, i have a computer, home charger and car charger and i drive for a living so if it gets low no biggie. In my opinion i dont see android going anywhere and i love the g1. Just like wm its gonna take time to get off the ground. To say its at a crossroads is ridiculous.
I am using ADP1.1 and yea if I am browsing the net with 3G for 3-5 hours straight I start seeing the battery go down. But from 100% to 0% takes me longer than 5 hours. I know because I like to lay in bed and don't care to come check my messages LOL
I bought a G1 last week and so far I have been really dissapointed. After having an elf and seeing other htc phones I was expecting big things from the G1.
I am now a week into ownership and after 5 full charge - discharge cycles I am managing to get 24 hours out of the phone with next to no use what so ever. If i check my emails and do 30 mins browsing the phone is dead in 6 or less.
The hardware is simply put 'very poor' my screen is wobbly and the back is loose, all this after just a week.
As for android, it is fantastic everything I expected (except hotmail support) and there is no way it is going to flop. Its just a shame that google and htc didn't wait until they had the right phone for the job.
Thats just my 10p worth!!

It all depends on what you have installed. for me the start up is. I beleve amazon does too, but I uninstalled that. But the first thing I do is go into task manager and kill everything. And only like two things auto start up. I really with HTC built in a x-button app for android. I loved the click x for close.

Under light usage I get about 36 hours from full charge to shutdown. That's GPS on, Bluetooth on, Autosync on, periodically doing e-mail and web browsing.
Under heavy usage (Which is basically I listened to MP3s for 2 hours) it goes at least 17 hours before I plug it back in. I haven't tested but I'd bet it could go 20 or more.
That's as good as (or better) than I was getting on the Wizard/MDA.
I dunno if anyone has stated it but the problem with the battery has to do with the phone recieving the cell signal. For some reason the phone runs in overload when searching for a cell signal...I noticed this one day when T-Mo suspended my service and my battery meter never moved all day, I think by night it was down to 85-90%...sure enough that night when I paid my bill and the phone started picking up signal again, the battery depleted at "normal" speed.

Why do i keep hearing that there is no hotmail support? Android (and G1) works with hotmail just fine! Just go to the Email program and set it up. WHY!! .. I am having connection errors sometimes though..
Battery is a big issue. Never had any luck with it.. EVER.. just unplugged it and after about 1+ hour it's down to 66%. Played a game (slide puzzle) watched 2 youtube vids of about 3 minutes each. And I had it fully drained and recharged a couple of times in the beginning. It didn't even took 10 minutes to drop from 100% to 89%.. But I was on wifi.. Maybe this is normal.
Software has a lot to do with this I think. Yesterday I had about 50-60% left. Did something, can't remember what, opening programs or music. And closed it. After 5 minutes I checked and battery was hot and had drained to orange level. I checked with task manager and only calendar/messaging/tunewiki/music was on. I closed all and restarted the phone, cuz it was still hot. Luckily it lasted a few hours till I got home, with very carefull use..

Nexus One Battery Life vs iPhone 3gS/4G

Earlier this year, I was a huge Android fan. I had a rooted G1 with a different firmware every week. My Dream ended when I realized that the battery was lasting me not more than 5-6 hours, even with very light use. This was after swapping out batteries/phones. Also, for working out, I needed a good music player. Android's default one needed a LOT of improvements.
So, when my friend brought over his iPhone, I decided to give it a try. I bought an iPhone 3GS from craigslist. Jailbroke and Unlocked it. The battery was lasting me more than a day, even after watching more than an hour of TED.com talks, and listening to an hour of music. The ipod functionality was amazing with the volume/music controls in the earphones.
Then, I accidentally updated my phone to the latest firmware... which cannot be unlocked. So I'm back to using my G1.
So, the question still stands.. Is Froyo on Nexus One better in battery performance and iPod functionality of iPhone 3GS. Especially with the upcoming iPhone 4G, we can be sure that Apple will increase the battery life of iPhone (as they've done with all previous updates)?
I get a lot better battery life with Froyo then on my 3GS to be honest. Also, as far as the music functionality goes, why do you think its so bad? If you dislike the interface, then you can download a alternate option from the Market. But for me, as long as it plays the songs, view/edit playlists and browse the music I am good to go.
i got slightly less battery life from my Nexus with 3G turned off compared to my jailbroken 3GS.
normally ended up with about 10% less battery at the end of the day compared to my IPhone and similar usage.
the Nexus was stone stock.
Thanks for the replies...
To answer the question about music interface... I think the ipod interface is much smoother than anything i've seen in Android (please suggest something in case I might've missed it). As I mentioned before, I use the earphone controls A LOT.. and am not sure if Nexus One will offer the same functionality.
Battery life is a huge issue for me. As I said, my usage on iPhone was pretty heavy. Let me lay it out here -- this is with Edge.. Push On.. and Location On.
- 1.5 hrs music
- 1 hr video (Ted talks podcast)
- 1.5 hr phone calls
- 2 hr games
- 3 hr Wifi on
With this kinda usage, my iPhone would have 15-20% battery left by end of the day (midnight usually)...
Does your Nexus One match that or is better?
( I'd love to switch to Nexus, if battery is a non-issue... love the Google integration!)
Battery life is across the board on the N1 for some reason. People will have the same set up and get very different kinds of battery life. I know I've never been happy with the battery life of the phone.
A good music player is ³. Cubed. I like it. I recommend the Nexus One if you get the 2 batteries and external battery charger for 20 bucks deal off of eBay. Maybe life will increase but until then having an arsenal of batteries solves my problem.
Ok, I guess I'm back to 8th grade, basic math. Let's calculate. And because you could have just looked in the specs and done the math yourself, I'm not going to look there, and if I bring the wrong numbers - so be it.
1.5 hr of music is almost nothing. Music is optimized for very low battery usage - 20 hr of listening or so. Let's say, 5% off battery.
Wifi on is nothing. You can keep it on for as long as you like, you actually save battery - it turns off 3G/HSDPA and uses WiFi data.
1.5 hr phone calls out of ~6 hours spec ~= 25% battery off.
1 hr video out of 5 hr spec ~= 20% off.
2 hr games are quite destructive. Both CPU activity and display. Let's say, another 25-30% off.
You're left with approx. 15-20%. Surprised?
Oh wait... It figures, no? Do you think one of those systems is going to be significantly inferior in terms of battery life? You don't think Samsung and Qualcomm know their stuff well enough?
Ah, and the difference is going to show if you use Android power and load it with zillion auto-updating and auto-syncing widgets, that'll chew on your CPU idle time and use up your network power.
[edit] That's exactly the reason for varying battery life between users, as the poster above noted. People use their phone differently, and unlike iPhone, it can perform a lot of things simultaneously, without you even noticing (it's enough that you installed auto-syncing widget and made it sync once in 5 min with a good amount of data, for example) - and it'll cost you battery life. Control what you're running, and you'll get more out of the battery.
I came from an iPhone 3G to the Nexus One and the battery life does seem worse. it's always hard to compare because I do more with my Nexus One. My gut feeling though is even if my usage is similar to what I would have done with my iPhone, the Nexus One just uses more power. Part of that may be the higher res screen. Battery usage almost always shows the display as the biggest user of my battery.
I recently have been having worse than normal battery life. I'm not sure if it's due to upgrading to Froyo or if it is because I turned Latitude on. If it's Latitude, then it's really frustrating that the Battery Usage area doesn't list Latitude as using my battery. Kind of makes that a pointless feature if things just get hidden under names like "Android System".
I also agree with you on the Android music player. I use it, and it's not terrible, but the iPod app on the iPhone is just much easier to quickly get to the music you want to play. Also the Genius features are really well done. Someone suggested Cubed. I found it gives a really good first impression but once you use it you realize it's actually just flashy and it functions awful. As far as I can tell there's no way to quickly find and play a single song with it.
Battery life for 3gs is better than nexus..
For my usage the battery life on Froyo is about twice as good as the battery on 3GS. Granted, I listen to slacker radio while browse websites for about 2 hours a day and the multitasking on android is much more natural than the jailbreak alternative.

I am not altogether sure you aren't just trolling. There isn't any way to give a definitive answer to this question, but I'll give you my experience.
No new N1 user is going to say he gets good battery life. You won't want to shut the screen off for the first week.
Now, I can get a day and a half out of my battery on a stock rom if I don't sync absolutely everything frequently, I use wifi when it's available, keeping radios I am not using off and basically, being mindful of power use. I use it frequently, but not constantly. And if I am away from a charger, I have an inexpensive spare battery that I can change all by myself without any special tools all the while sending SJ a FU via ESP.

Lemme get first thing straight.. I have NO intentions of trolling No harm intended. When I bought the iPhone, EVERYONE I know was immensely surprised. I was (and still am) a spokesperson for Android. I love the apps. Maybe thats a reason that we all install so many widgets/apps which use data.... So many are available for free!! and awesome ones too.. for example.. I'd kill for the News and Weather app to be in iPhone.. but its not...
As I said in the original post.. a big chunk of my criteria is battery life.. second big chunk is music... I guess I'm sad that no Android phone yet can beat the battery life that an average iPhone user gets... I was hoping by releasing Froyo, google would change that (hence this thread)...
Trust me guys.. I live by my gmail.. would rather have everything centered around it... than having apple control my life... just dont wanna carry around extra batteries.. like i had to for my g1...

Something that people keep mentioning but seems to keep getting overlooked when people compare any device running Android to the Almighty iPhone...
Multitasking. Takes. More. Power.
Being able to run 5 or so apps in the background (along with all the automated syncing that's happening on the network-data side of things) is going to drain the battery more than doing one thing at a time on Apple's product.
When your iPhone is able to effectively multitask, come back and then you can compare the battery life.
Quite simply, Android lets you do more than you could ever possibly do on the iPhone platform. It gives you the option (free will - unheard of on the Apple side of things!) to run a handful of apps simultaneously. This, naturally, uses more power as the processor is doing more. This is not rocket science, people. You choose to do more, so accept the power penalty. Or, you can be mindful of your battery usage and manage things appropriately to get a significant battery life improvement. It's your choice!
And if you still don't get enough battery life out of this more powerful, more capable device, as attn1 pointed out, there is absolutely nothing to stop you from getting an inexpensive spare battery that can be swapped into the phone in under a minute (INCLUDING the time it takes to shut down and power back up).
Trying to compare any recent Android device to Apple's iPhone is like comparing my gaming notebook to my old TI-84 graphing calculator - which did get much better battery life than my current Asus G72 notebook.

In 2 hours doing what I noted here I lose close to half my battery?! That's laughabad.
It's amazing how all over the place the returns are.
I have owned the following phones in the last three years :
iPhone 2G
iPhone 3G
BlackBerry Bold
iPhone 3GS* (borrowed for 2 weeks to see if I wanted to go back...)
Milestone
Nexus One
I, personally, got the best battery life out of the iPhone 2G - I got three days out of it, consistently. BUT, I did not have an unlimited data plan, I did not use it for mail, I always got apps from the store over WiFi, I never streamed music, video or anything else. I had no RSS reader. I listened to some music, played the OCCASIONAL game, sent some texts and made a few calls.
Next would be the Bold. I POUNDED that thing and ALWAYS got at least 2 days out of it. I would send dozens of SMS, read and reply to at least 40 emails/day, use GTalk with my wife for at least 50 messages a day. I'd read RSS feeds with Viigo.
After that, every single phone on the list requires charging every single day.
On the iPhone 3G, I would do a little surfing, maybe a little video, some emails and some text. Music on the metro coming and going to/from work. Charging every day was mandatory.
On the 3GS, with how App Store had better and better stuff, I killed it (as in forced shut down) 5 out of 15 days - all that with no widgets and no multitasking. I would read Le Monde, do some browsing, read tweets, read emails, make a couple of calls and texts. I started stocking the charge cable at work and in my backpack during my weeks with a 3GS, because it wouldn't make it through a day. Most friends and colleagues who have them do the same.
I received the Milestone in December. I loved it, and really started pounding a phone - 100 GTalks a day, some SMS, all email, NewsRob for RSS, Le Monde, News & Weather widget one we hacked that on there (following the Jan 5 release of the N1), twitter and facebook, browsing. App downloads, widgets left and right, plus CONSTANT dev work, image building, flashing, testing, etc. I would get a day if I took my foot off the gas, but if I pushed it too hard, I would kill it. There were a couple of battery killers that were avoidable but which I didn't avoid from time to time - leaving Qik, the browser on the google homepage (with autolocation on) the Camera or Maps open, then letting the phone go "idle" with the screen asleep keeps the GPS on and would eat the battery in an hour or two. This left me high and dry a couple of times, until I paid a bit more attention. The Milestone got better 3G than any iPhone and worse / less-consistent WiFi.
I picked up a Nexus at the beginning of March. It gets somewhat-to-significantly better battery life than the Milestone. I still have to charge it daily, but there seem to be fewer battery-death bonehead choices that drink the go-go juice and leave you without your electronic BFF. Most of that is probably Android 2.1 and the UV kernels - I noticed that the Milestone was better with 2.1 as well. It also gets 10dbm worse radio reception with the same SIM on the same desk on the same network in the same office. But it gets MUCH better and more reliable WiFi, and that is better still since FroYo. I use it a ton - RSS, chat, SMS, calls, LOTS of browsing, Le Monde, NYTimes in Newspapers Full, lots of games in spare time, Google Listen for Podcasts, Music, Movies, taking pictures and videos and posting them online with Twitter, Facebook, YouTube or Buzz, etc.
The Nexus has one MASSIVE problem, as far as bettery goes - charging it on any computer USB port, and many thrid-party USB charge plugs (AC or DC) is atrocious - hours and hours to get just a few percent. I don't know why - Apple can use 1A from anything, RIM / BlackBerry can come close to 2A. My Milestone would take at least 1A from anything. But the stupid HTC kit won't take more than about 400mA from a computer or a non-shorted USB charger. SOME 3rd party stuff will be exploited up until 1A, as will the charger that the N1 comes with, but if not, you're going to see slooooooow charging.
As far as the music player: I want 2 things - good sound and the ability to pause and skip with the mic button. Every iPhone does this, and so does the N1. The N1 DOES support headset buttons (it's own set comes with them), but I use my Shures with a simple mic adaptor. I almost never see the interface - I put on a playlist and shuffle it. DoubleTwist makes sure that I have the same lists on my iPod touch and my Nexus, so I really don't notice the difference.
If you use the interface a lot, well, then the player on an iPhone is the best there is. I just don't use the interface often enough to make that a selling point.
As far as sound - the Milestone got SIGNIFICANTLY more volume and better sound then any iPhone and a ridiculous amount more than an N1.
Froyo just rocks. I miss a couple of CM features, but there are sooooo many good things baked into Froyo - tethering, copy/paste in received GMail messages, SD card app storage, cloud-stored settings, Flash, incredible performance.
Your Mileage May Vary.

Thanks for the VERY detailed post... And also for clarifying the controls thing... thats awesome that N1 uses the mic button for controls... I use it a lot while running to skip songs...
I'm on the brink with my G1 though... Flashed the latest 2.1 ROM from Cygo.. at first I thought it was fast.. but now its driving me crazy.. its not really the ROM but the phone itself.. will post a video of the experience soon..
So to summarize above posts...
- N1 can give same or better battery life than iPhone... provided.. that we use it well... no crazy widgets/apps which keep using data...
- The earphones button CAN be used in N1 to skip songs.. which is awesome for me...
I think I might order my N1 today itself.. as it's still being sold on google (surprisingly enough).. Who knows once only T-Mobile sells it, if they'll stop offering the unlocked option....
Thanks for all the input guys

Buying A Samsung Product

I have had every GSM android phone Available in the USA, as well as the Rogers Magic from Canada & European HTC Hero.
HTC has been Extremely amazing with their products and if any issues, they were very helpful.
Ive Read more bad things about Samsung products than good such as electronics dying a few months of being purchased brand new and their support being the worst.... I am a little shaky to buy the phone due to people commenting feeling like straight up plastic. and also because i would be pretty pissed for it to die just a couple weeks, or months from purchase date.
Anyone Experience anything wrong with their phones so far? Hardware Related???? Now Samsung also sucks with Updates and Promises, Just look at the behold. Seriously!!!!!!!! --- Flame, flag, discuss, be of use, do your thing-----
The various radios and their ability to hold a strong signal when touched by your hand is definitely a concern. Indoors, 3G reception with this device is extremely unreliable. I fluctuate from having full signal strength (not just going off of 'bars'), to EDGE, to dropped calls. I've had calls go straight to voicemail, while the phone is sitting on a desk, where other phones did not have this issue.
Outside, depending on how 'obstructed' I am, it's a bit difficult to drop. But if I walk between two houses, 3G signal is screwed. Blame it on the frequency of T-Mo's network, I guess; but I have used 3G phones on the network which have never suffered from these problems. A co-worker of mine uses a cheapo 'MyTouch 3G', which outperforms my $500 phone in terms of 3G strength and GPS-locking. Really sad.
The screen is incredible. The best in the industry, if you ask me. The pixel density isn't as crazy as the iPhone 4's, but the colors are unmatched. Watching videos on this screen is like sitting in front of a tiny Plasma TV. Speaker quality is actually quite decent, to boot. Sounds about as good as the speakers on a MacBook Pro.
The build quality is solid, for what it is. That said, it still feels like a toy, and is probably built from cheap plastic to keep the costs down (the screen probably costs a fortune). I would've preferred a heavier, metal-body phone.
The buttons, unfortunately, feel very cheap. My biggest concern is that the power button might fail some day. The headphone jack is cheap. In fact, my first headphone jack was non-functional, and would constantly short out.
Despite all of those hiccups, I still really like the device.
Samsung's support is not the greatest, which is why I worry in the first place. In 2003, I bought one of the last CRT HDTVs. It was an issue of 'spend $1k for CRT or spend $3k+ for LCD'. I was broke, and in school, so I went with the CRT. After a year of mild usage, the board inside of the TV died, and I could only view snow-laden black and white images. The TV was covered by the extended warranty I bought through the store. A year later, on the dot, it died again. And the next year, again. Eventually, I grew tired of spending money on warranties, and let it lapse. Sure enough, the TV died again. From that point on, I was skeptical of Samsung's QA. They wanted to charge me the cost of the TV to repair it. Needless to say, the set was junked, and I wasn't happy.
I still don't like their build-quality. I think Samsung cheaps out, even on their larger sets. Everything is thin, glossy plastic. But one thing is for certain: Samsung knows how to build a panel -- the best panels in the industry, if you ask me.
That's all I really have to say about them. Hope it helps.

Surely you jest.
Go troll somewhere else.
@Jon C
Thank You So much for you detail reply, and the use of past experience as a reference. I may just hold on another month and see what else comes out if not, ill just go with the Mytouch Slide ...... Either Way Thank You Very Much.
Galaxy s is samsung's flagship product it's being launched globally, I don't think they are in position to let it die as behold. But it's my own opinion though.

I would just like to add my 2 cents as far as battery issues.
1. I use task killer to disable unused apps and free up ram/cache info and save on a little battery power
2. i setup the brightness manually to be low and the phone is still very bright. The phone on average uses 80-90% of its power from this alone so it is VERY important to manage. I used it auto on the first day and the phone lasted me about 12 hours. Once i set it up manually i got about 14-15. For example 8am-11PM. With lots of use. The phone battery seems very realistic to use in a single day..but more than 20 hours i would say you would have to have moderate to low usage..i would say i have high usage..1st day i had it with a full charge

the rest just browsing on the phone setting up emails and such
please feel free to email me with any specific questions: [email protected]
I love this phone!
Update: 07/21/10
Today is the second day i use the phone fully and using it for just about the same amount my battery is only about 47% compared to 30ish% the day before..last night it crapped out at around 1145 with 5% energy..its 8pm now and im at 47%..so far i have charged it fully 3 times..i expect 2-4 more charges and im gonna get a max time of about 15-18 hours of hard use..LOVE THIS PHONE!!

Solution to Desire HD battery problem

Having tried just about everything to prolong the life of the battery on my Desire HD, I think that I have, at last, found a real solution.
I did not like the idea of buying a spare battery mainly due to the flimsy battery compartment on the phone and the thought of constantly swapping batteries. Swapping batteries would also involve switching off the phone and losing data (for example, if you are using GPS to track your movements).
I have tried lots of software solutions, most of which help to give me an hour or two of extra life. My favourite software solution is Juice Defender, which works well within the limits of HTC's awful battery.
Someone on another thread recommended the TechNet external charger, which packs a 5,000ma charge - enough for four full recharges of the HD phone. It plugs into the micro USB port on the phone and charges the phone as though it is connected to the power supply. It hot-charges, which means you don't need to swap batteries or switch off the phone. The device comes with lots of adaptors to charge lots of different devices. There is also an 11,000ma version... enough for 10 recharges.
Available on Amazon:
http://www.amazon.co.uk/gp/product/B000NDQ92W/ref=oss_product
It also looks good and comes with a travel pouch and is smaller than the HD phone itself so slips into a bag without a problem.
Looks promising. Thanks for the info bobby!
I purchased this before I went back to nz for Xmas. Well worth the purchase, has saved me several times. One thing to be mindful of is that if you accidentally turn it on without realising, the battery will drain, even if its not charging anything.

Is the battery really that awful? I can use the phone for 24hrs (including stand-by time, 14-16hrshrs of usage time) with wifi, 3g constantly on until I need a charge.
Which is really more then enough time for me in between charges, unless you go on trip for days without access to a computer or an wall socket.
Its nice to have a phone which last for days like the old days, but it really has no inconvenience charging it once a day, right?
+1 , left my phone in work the other day after reasonable useage in the time I was in work 0900-2000, came in the following morning , to find 13% charge remaining and that was in-spite of my alarm going off
I find that if you put your phone in power saving mode, even the remaining 10% can last you for almost a day.
Its quite useful if you know you gonna leave ur phone for a period of time.
Actually it would be quite useful to have a toggle widget to do that on ur home screen instead letting it activating itself below a set percentage. Is there any?
Howdy,
I was so frustrated with the battery usage I nearly ditched the phone. I decided to apply a different rom after reading and considering many posted here I went with Coredroid, which I downloaded from this site. (had the original vodafone rom) Great support and documentation and tons of help if it goes south.
I can say as of now my phone is 5 times at least faster and the battery life has extended 300%.
When you check battery usage the I found the number one battery killer is Display. With Coredroid its about the 5th item on the list. Wireless and bluetooth and the biggest now (if you can call them real big) but they are easy to turn on/off.
I was very nervous about a custom rom but I needed something. I can only recommend you look at other roms apart from you stock one -Im assuming. (Im not sure what warranty etc rules are gone, personally I don't care)
Cheers

Yes, that was me, with the external battery pack/charger
Well, it's a heavy phone already, a huge screen to light up and render -it's pretty clear where the power is needed. But would the bulk associated with another 400mah really have tipped the DHD over the edge?
Anyway, it's designed now, and nothing can be done about that. I'm quite happy with it lasting until the night for normal/heavy usage (about 16 hours) - with it's out-of-the-box form factor.
And for those occasions when I'm using GPS tracking apps out in the open for 5-6 hours, broadcasting my location to a website, hooking it up to the external pack (mine is in fact a New Trent one, 5000mah) means it won't drain unexpectedly. That is, with 5000+1260mah combined!
The battery pack provides a "full" charge in about 2 hours, that is just like a mains charger (it is rated up to 1amp output, providing of course whatever amperage the device pulls).
That pack might be a solution for the battery problem, but I still don't think it's enough. I don't think that you should have to buy a portable power pack just for your phone battery to last. The whole point of mobile phones is that you have access to a medium of communication in a remote location. By not making the battery life long on a phone, I reckon HTC are actually limiting its main use. But that's just my 2 cents, and it does depend on how people like to use their phones.
5000 mah is not enough, why not make it larger
Thanks for the info.

You must love the 1240Ma battery that comes with the phone.
You've enabled USB Debugging, yeah? I get 2 days, and I work in the middle of nowhere. The phone polls for a new cell constantly while I'm in my office.
If signal is good in your area, tell the phone to use GSM or WCDMA exclusively. Otherwise it will switch to whichever has the better signal, which can be problematic is you're in an area with good / poor coverage of both technologies.
I think the polling thing might be a big battery killer. I shall try that.
I friend of mine in the office, use to have a Sony smart phone that barely lasted a day and thats on standby. He ditched that for a DHD. His battery now lasts 4 days plus, with minmal use! Mine on ther other hand with minimal use can give 2days at most.
The difference is that he is on ORANGE and I am on T-Mobile. It must be down to signal strength because he use to be on THREE and the signal strength was very poor at his home location.
BTW, I find that Juice Defender does help and switiching off Flash in the browser.
This charger and the USB-Batteries are the best inventions ever
It would be great if this phone got accessory support like the fruit phone does. An extended battery case would be the most optimal solution to this problem but I haven't heard of any out there yet
P.S send me a PM if anyone finds an external battery case
how is it compare to eneloop 5000mah?
Ah! I need that one for when i go camping

A brief comparison of popular phones

I had a Droid Turbo for 1.5 years that got great battery life. I am a power user, and averaged between 4 and 4.5 hrs of SOT in a 16 hour day.
For no good reason, I decided it was time to get a new phone, and I chose the S7e SD 820 model based on the reviews. While the phone is pretty, there were two dealbreakers for me. First, the Edge screen is too sensitive given the way I hold a phone, even when using a case. I'd constantly open apps on the left side of the screen by accident. Or worse, make weird typos in emails. The second, and bigger issue, is mentioned ad nauseum on this forum - the US version has major Android System battery drain that has not been addressed. I spent hours and hours trying to get in touch with someone who could help me at Samsung. I was promised callbacks, fixes, etc.. But when there was no follow through and I'd call back, they acted like nobody had ever reported the problem before. I then tried tweeting Samsung support, and they responded... By telling me that their customer service dept on Twitter has absolutely no way to contact someone who can solve the android system issue. Finally, after calling several times, I got in touch w a US based tier 2 tech support agent, who also told me the issue had never been reported. He had an S7 on hand, picked it up, and noted that there was definitely a problem. He put in a ticket but said it wouldn't be addressed until enough people complained to trip their system. Given the challenges of dealing w Samsung, and my big priority of having a long lasting battery, I finally gave up hope and returned my s7e to Verizon. This is the first time in 20 years of cell phones that I've ever made a return.
I wanted my Droid Turbo back, but unfortunately, I turned that in when I got the S7e. So, I decided to get a DT2. I'd call it a fine phone. Nothing special that differentiated it from the original for me. In fact, battery life for me averaged about 3.5-4 hrs SOT, less than the original. If I'm going to spend $700 on a new phone it has to be significantly better than my previous one in the category that's most important to me, which is battery life. I don't watch much video on my phone, but I definitely use apps intermittently throughout the day, including FB, Instagram, Bumble, TouchDown and Feedly. Since those don't need anything special in terms of graphics, my only goal was to get more device use time than the DT. Since that wasn't happening, I've now purchased a Nexus 6p.
From reading the forums, it sounds like Google is much more responsive to issues because this phone is running stock Android. While the processor is a generation dated from the S7e, I do appreciate that Google will update much faster than Samsung, who barely acknowledged a battery issue affecting 100% of US phones. I've now installed everything on my 6p, and am in the middle of testing it for "normal use" (meaning, how I use the phone, which may or may not reflect the norm). If this phone doesn't get better battery life than the DT, then I'm going to return it, call it a day, and purchase another DT on ebay.
I'm sure for many of you screen pixels, camera and processor speed matter, but I don't watch much video, find almost all cell phone cameras provide pixelated photos, particularly in low light, and I never had any issue opening FB or emails at warp speed on my Turbo. I can't justify getting equal or less battery life for a phone that costs $500 more than the original DT.
Anyway, I'll give an update once I've had a few days with my 6p, but feel free to post your experiences if you've had any of these devices.
You should be able to get at least 6 to 8 hours SOT with the SD820 Edge, just look at this threat and try it. Despite your bad experience so far this S7 should easily obliterate your DT and 6p. It's just a shame 800 bucks doesn't work great straight out of the box like most Exynos do and how it should be. But even Exynos isn't perfect, e.g. my standby drain is slowly creeping upwards from 2% per night on the first day till 4% now, 2 weeks later. Without ever changing a setting. Not complaining though This phone has potential like no other phone in market does at this point in time.
I'd strongly doubt that any phone could average 6+ hrs of SoT unless you're on wifi and using the screen continuously. But again, everyone uses their phones differently. For me, it was the terrible Samsung support that made me throw in the towel. I agree that the phone has potential, but potential is just that. If the people responsible for updating the phone don't pay attention to their customers than the phone will never improve beyond its potential.
