A Note on Charging Issues with The i727 and possible i727r Skyrocket - AT&T Samsung Galaxy S II Skyrocket SGH-I727

For folks that are experiencing various charging issues, especially slow charging, and or inability to go to deep sleep after charging, I want to point out something that folks may be doing without realizing the pitfalls of doing so.
DO NOT CHARGE YOUR SKYROCKET WITH A DIFFERENT CHARGER THAN IT CAME WITH​.
Here's why: The Skyrocket actually come with a 5v 1.0 Amp Charger. This is a higher output than similar phones, even the regular Galaxy SII from AT&T uses a significantly lower output charger. The best reason I can see for this is the large stock (1850mAh) battery in the Skyrocket, put there to help overcome the demands of LTE, which is a bit of a beast as far as power consumption.
This charger appears to be the same one Samsung ships with the Note, a device with a huge battery, though I have only been able confirm this by a visual. But this shows what Samsung's intent was. And a properly working charger should completely charge the Skyrocket in a couple of hours if turned off, 3-4 if running. Any longer and something is not right.
That's okay, since it is power "well spent" in my opinion, assuming you are actually in an LTE area. Those that are not though, I would have considered carefully the price you pay (in battery life) for no appreciable return, unless you are in a "coming soon" area, which is actually true for many Skyrocket owners. Alternately you can root, and use appropriate tools to drop back to HSPA+ or (shudder!) Edge.
The 1850mAh stock battery is decent, removable/replaceable unlike the new trend of sealed battery compartments, and it's possible to cram a Galaxy Nexus Battery in there (barely, and some have been unable to).
For problems with deep sleep, there is plenty of anecdotal evidence that unplugging while the screen is ON makes some difference, though in my testing (with a single example; my own phone) I could not reproduce this.

even if i dont use lte it still drains? im on rogers so its rat unlocked. how can i turn it off?

I use an iGO 5.0v 850mA USB wall charger and I also use the GNex extended battery. After charging all night I unplugged charger and let it sit for 19 min with screen off. Of that 19 min, according to CPU Spy, it spent the entire time at 384mhz and not 1 sec in deep sleep.
I rebooted the phone and ran the same test, this time it spent 97% of the time in deep sleep and the rest at 384mhz. Pretty conclusive if you ask me.

i used to notice this issue, but on the most recent CM9 nightlies (from about 7/2 on) the issue has went away. this is with both the charger that came with the phone, as well as the one that came with my captivate, which i have a usb extension hooked between the charger and the usb cable.

I think usb extension messed up my cord, not sure yet have to confirm it but I have no idea why just recently the cord has been transferring at 1mb/s~ to my SDCard. Not my SD card because I put it on my USB adapter and it was going 10-15mb/s I'll test with the s3's cord lol

Battery Charging Issue

I know there is a bug in which after an overnight charge, the unit is unresponsive unitl you soft reset it. I've read the thread. My TP exhibits this problem as well. However, mine seems to have an additional problem not mentioned in that thread. After charging overnight, my TP IS NOT CHARGED! After an overnight charge, the battery is nearly dead and a soft reset does not fix that. It has happened several times now. After plugging it into the charger before bed, I confirm that the charge light is on and that it shows charging on the status screen, however, THE BATTERY IS NOT CHARGING. Has anyone else experienced this quirk? It doesn't always do this, however, so I'm very confused about what is happening.
Dumb question - but are you using the factory charger? I had a problem when I purchased my Touch Pro in the fact that I used another charger which also was USB for another phone, but for some reason had that problem. Using the charger supplied with the phone fixed it.

Yup. Factory charger and cable. Not a dumb question, BTW. That could have very well been the problem although any USB charger should work.
What about if you turn the phone off and charge?
On a related issue, I used TomTom the other day for a 1 hour trip with the phone on a USB lighter socket charger. Started with 48% full battery, when I finished the battery was down to 30%!!! Basically the phone uses more power than the USB can provide when the screen+GPS is on!! I also find plugging the phone into the charger with the screen on & WiFi on will mean the phone charges at a speed of 1% every 8 minutes - taking all day to charge from empty!
To ease the problems I purchased a separate phone+battery cradle off eBay and a spare battery. I swap to the charged battery every morning and put the other one in to charge. The used battery is usually at 25% after a good days use. Before I did this and charged using the USB plug I used to get 6 hours use before needing to re-charge.
Disconnect the cable from the factory charger and plug in in your PC, see if it charges there. If it does, then you can return your charger, if it doesn't then i'd return my TP.
I have had the Touch Pro for eleven days(got in October 31,2008) and I have issues with the phone. First, I love this phone, however, the battery will not hold a charge. I started with a fully charged battery, used sprint navigation to direct me on a 2 hour trip. My phone was dead by the time I got to my destination. The phone was extremely hot, I mean extremely hot during the entire trip. The next day I took the phone into the sprint store and they switched the battery and told me that the phone check out okay. for the next several days, i used the phone sparingly to see if the battery was okay. I made about 7 calls and 12 text messages, my battery was down 3 bars after being fully charged. I tried the navigation within the city limits and the phone again stared to get hot. My sprint picturemail would not work, it takes hours to send a picturemail. I call customer care and talked with technical support, who did not have a clue about the phone, they had me on hold, researchec, told me to do a few things and then had me to perform a hard reset. The picturemail worked for a few messages and then it started to take hours to send a picturemail. i then went into a sprint store for ready now service to see if there was something I was doing that was causing the battery loss, etc. The CSR in the store did not have a clue about the phone. He went through the computer told me a few things to do and that was it. My battery continued to perform poorly, so I again called customer care and was told afte a serious of conversations and procedures that i need to have the phone replace and that my phone could be defective. They told me to go in to a store and have them make the switch. Well, there are no phones in any of the stores in my area. I call customer care again and asked them to look at the notes on my account and send me a replacement phone, because there are none available in the stores. That was a horror story and i currently have an expensive phone that i have to keep on the charger. i actually purchased a universal charger from sprint that can be used in your car and/or in a wall socket to make certain I don't lose my charge. I think the phone is over priced for how it is operating for me. Sprint should provide an additional battery for the touch pro like they do for the Instinct. The should also include the universal charger in the box. The phone cost to much to not operate better. The sprint picture mail sucks, The sprint TV sucks, but the phone is really nice, if sprint can correct the issues mentioned.
I don't charge it at night cuz i don't like to "overcharge", so i usually charge it when i get home b4 I sleep. I have been considering getting an additional battery with a dedicated battery charger from HTC though. ever gave that a thought?
I seem to be having this same issue with my Fuze that I just got yesterday. After a full night on charger it's at 82%. I'm going to try it over usb on pc to see if it gets any higher otherwise I'll be taking it back to the store today.
The HTC touch pro (with factory ROM) is protected from overloading. Which means that overnight it will load for about 3 hours from an empty battery and then it is full (white light will go from sliding to full circle). After that the charging stops. Which means that if you sleep for 8 hours, the remaining 5 hours your phone will be using the battery.
Now the question remains, what is drianing your battery in 5 hours? The initial suspects are GPS (any GPS software should be cleared from memory, press the most right corner icon to see what's running), the wifi or the HSPA / 3G connection. Use comm manager to put those off.
Of course, the second option is that the charging is not happening because of a defect, in that case return it to the shop.
Pretty sure this is a common problem, I don't think returning the phone will solve a thing.
My phone does the same. Though if you charge it with the phone turned off, it charges fine. I purchased a separate charger and spare battery and just swap them over when I need to (1.5 days with moderate usage).
Pretty sure this is all down to the phone using more power than it should be, hopefully future rom updates will fix this. Even when using Tomtom in the car with the phone charging on a USB cigarette charge cable can't charge it - it actually has less charge at the end of a long journey.
Oh and I can also mention that I have the original HTC battery and two spare batteries (which look like copies with, the HTC sticker is there but not quite the same). The spare batteries act just the same as the original HTC battery.

[Q] Charging Interrupted - Battery Temp Too High or Too Low

I recently received a Droid Charge from Verizon as a replacement for a Thunderbolt which was basically rendered inoperable by the May OTA update due to near constant rebooting. I really like the Charge (with the exception of that hideous brown/orange theme - some of which looks designed by 1st graders!), but I'm having a MAJOR problem with it that I haven't seen mentioned anywhere else, and I'm wondering if I'm the only one suffering this issue!
I drive a tractor-trailer for a living and use Google Navigation as a back-up to a truck-dedicated GPS unit I have in my tractor. I have a dash mount that I used to keep my Thunderbolt in and I had no problems with it at all (except for the constant reboots). However, the first day I was using the Charge, the screen went dark all of the sudden after a couple of hours, and I'm like WTF?!! I couldn't get it to anything, so I pulled it out of the dash mount and let the sun shine on the screen - I saw the display was still on, but it had dimmed to the point that I couldn't see it without a light shining on it. In the middle of the screen was a dialog box with an exclamation point and the message "Charging Interrupted - battery temperature too high or too low"! I unplugged the Verizon-branded car charger and as soon as I did that, the screen became bright again, and the message disappeared. I left it like that for a while, until the low battery warning appeared. I then plugged the car charger in and let it start charging. Well, guess what? It darkened the screen again after almost 30 minutes of being connected to the car charger, and I saw the same battery temp too high message on the screen!
I have since tried to use the wall charger I got with my HTC Thunderbolt (my tractor has a power inverter in it, and electrical outlets to plug a power cord into, just like the outlets at home), but I got the same warning message on the screen. This is a REAL problem as it's basically causing the phone to be unusable, since I am not able to charge the battery when it gets low, due to the phone interrupting the charging! I went to a Verizon store, thinking it might just be a bad battery (especially because, when I first put the battery in the phone and plugged it in to charge, I got an "Incompatible battery" message on the phone). I took the battery out and reinserted it, and I never got that message again. Verizon gave me a brand-new battery, but that didn't help. They sent me another Droid Charge to replace the first one, but the 2nd one is doing the same thing!
Anybody have any idea what's going on here? I've had the same problem now with 2 seperate batteries and two seperate Droid Charge phones, but I never had that problem with my Thunderbolt, even though I used the same wall & car chargers with IT! The back of the Charge's are getting very hot, but, then again, so did my Thunderbolt, and I never had a charging issue with it. I'd really like to keep the Charge and send my Thunderbolt back to Verizon, but I can't do that without finding a solution to this problem!
Thanks,
Dennis
I used to have this issue with several HTC phones. What happens is that if you keep the phone on the dash in direct sunlight, the battery reaches critical temperatures and to prevent the risk of failure, it stops the battery from charging. This happened all the time on my HTC phones from the Mogul 6800 to the Touch Pro. Not sure why the T-Bolt didn't have that issue, maybe it was set to a higher threshold before stopping the charging.
You may want to keep it out of direct sunlight or take the battery cover off to let more air flow in when charging on the dash.
Hope that helps.
I had the same problem. The warning message seems to be a safety feature built into the Charge that waits to charge the battery until it is cooled off.
I found that unpluging and turning off navigation for a while helped cool things off.
I also tried having the phone fully charged before using it for navigation and then plugging it in and this seemed to help. I am no expert, but it seems that when the phone is not trying to charge a battery rapidly it deals with the GPS heat better.
I hope this helps; stick with it and keep bugging Verizon!

So they sent you a Charge, but you kept the tbolt charger? And they have sent you multiple Charges and batteries, but never the correct charger? If this is right, you need to tell them to give you a Charge charger (heh). This phone seems to be pretty particular about what charges it, I can't even use a usb extension cable, so the wrong charger may be the culprit.
I've been getting this as well using CoPilot Live v8 (just upgraded to v9). I found if I turned down the screen brightness a bit, say to 80%, I could still see the screen but avoid most of the battery charging issues.
I also just purchased a Tetrax XWAY mount that will attach to an air conditioning vent. We'll see if blowing cool air onto the back will let me drive around with the brightness turned full up.
My concern with brightness all the way up is that I am not sure if the charge rate from the lighter plug will keep up with the discharge rate on the DC when everything is running full tilt...I just ordered a Tek-Tok Wireless lighter plug USB charger, Input: 12-24V DC; Output: 5.0V DC 2.1Amp! Let the frying begin!!!
p.s. I tried the Samsung/Verizon navigation mount on a 5-day trip...not too bad of a design, BUT, would not work with my extended battery and back PLUS when the DC goes into car dock mode (automatically when inserted into the navigation dock) it comes up with a screen that has a shortcut to VZ Navigator that CANNOT be edited or changed to another navigation program. You have to disable the dock in order to use another navigation program! What's with THAT, Verizon and Samsung!!! Needless to say, returned the mount yesterday...
Try turning your brightness down, make sure it's going into sleep mode and keep it out of direct sunlight
I also had the exact same overheating issue. After getting a replacement device I started looking at the charger I was using. I had been using a micro usb charger that only output 500ma. The droid charger is 1000ma (or 1 amp). Apparently I was using more power than the charger could provide. The charger couldn't keep up and I guess that must have been the issue because since switching to a 1 amp charger, I haven't had overheating issues.
"Charging Interrupted - battery temperature too high or too low"
Living in Miami, I have seen this message a few times after leaving the Charge in my car.
Run a free sensor program to tell you the battery temp when it does this. Mine gets up to 130 F.
If your phone isnt really at 130F, maybe something is tricking the sensor or it is faulty.
I rooted my Charge today, installing a new kernel (imnuts' PeanutButta Jelly Time) and a new ROM (GummyCHARGED 1.8.5), and I drove 3 1/2 hours from my terminal back to my home for the weekend with the Charge plugged into the charger and never once got the "battery temperature too high or too low" message!
I'm keeping my fingers crossed that doing this eliminated my charging problems with the Droid - we'll see!

Google maps updated and one of the new features is "Improved battery power management for Navigation (Beta)." Hopefully this helps to solve our problem!

One thing I did to help prevent this issue when it gets to hot is to set the air vents in your car to the defroster setting, so it will blow air at the windshield, and in turn your phone on the dash. Also, taking off the back can do wonders to prevent over heating.

[Q] Won't Charge Over 200mA?

I was searching around for something else when I came across people talking about their phones charging at 400 - 700 mA from the wall charger. Typically, mine won't charge any higher than 200 mA regardless if its in a wall charger or a USB cable, no matter how long it sits idle. The wall charger is the stock HTC and is in fact rated as having a capability of a 1A output. Interestingly enough, I have a car adapter that I use a USB cable with and I occasionally see ~350 mA from that one, but not often; it too is rated as a capable 1A output.
Also, twice now recently I have plugged my phone into the wall at night before going to bed and woken up to a completely dead phone. It happened again last night, but this time I woke up to it with only 35% battery instead of being dead, so it only charged 20% from the time I went to bed until waking up (about 8 hours).
Is this a kernel, firmware, or hardware issue? Nothing has changed on my phone in a LONG time. In fact, I am still running ARHD 3.6.7! I did flash the new OTA firmware fix at one point MONTHS ago however. I reverted to stock, got all the OTAs, then restored ARHD.
I looked for an app to make sure the phone is dropping into sleep, but I couldn't figure them out, anyone have a good thread or info on how to do that?
Thanks in advance!
~T.J.
did you check the cable?
Yes, I should have mentioned that. I do have multiple cables. I have the one the phone came with, two others from a previous phone, and the one that stays in the car. I have interchanged the cables with various chargers plenty of times, doesn't seem to make a difference, but I honestly didn't look hard since this is a newly discovered issue. I will try switching them around and noting what happens with each.
Thanks for the tip!

EDIT: I also downloaded watchdog from the market and my phone has been sitting idle for a while now, just checked and it says there are no misbehaving apps, whatever that means.

The n8010 charging problem - My second Note 10.1 is about to be returned

I thought it might be worth writing a post about my second tablet's failure before returning it as I'm not sure whether to get it fixed/replaced or look for a refund. Maybe someone has some thoughts? After suffering the apparent failure of two Note 10.1's I'm getting worried that there is something fundamentally wrong with this tablet.
Now, I should say here that my tablet was bought refurbished. It shouldn't make a difference- I've bought plenty of refurbished tech before and I've never had problems like this but I thought it might be worth mentioning.
So, the first Note arrived faulty. It would not charge above 17%. The charge up to that point was faultless... It just wouldn't go higher than 17%. That made me think it was a software issue but nothing I could do would fix it. Back it went. It was swapped on the door so I know the second tablet was an entirely new tablet (with new charger).
The second Note I received has worked for just shy of 2 months before it too is having a lot of charging issues. It will only occasionally charge now- most of the time I can leave it for hours and it won't go up 1% but every so often it'll start charging again. The lead is fine but I can't check the charger as I don't have another to try out.
Due to my paranoia of charge failure I've monitored the second tablet with 'Battery Mix'. The graph created by the app shows a perfect flat line when the ac adaptor is plugged in. That in itself seems weird... If there was no charging occurring, wouldn't the battery lose charge rather than remain at a constant level?
The flatlining behaviour is what has me worried. Both the tablets had the same issue, the first just stuck at 17% whereas the second will stick at seemingly random levels. But the symptoms of the fault are similar.
Searching the internetz reveals similar cases as mine and, seeing as a refurb device only has a years warranty, I'm not feeling particularly confident in a third Note behaving itself over the long term.
Oh, and after all that whinging... I do actually love the Note 10.1 when it works. It's a really nice bit of kit which I am loathed to have to return.
I have had fits using the supplied stock charging cable. I bought an aftermarket cable & it charges perfectly. Unfortunately, I broke the cable two days ago & had to use the stock supplied cable. Charging is so slow it is ridiculous. I plugged it in yesterday morning at 7% & today, 20 hours later, it is only at 22%.
With the after market cable, it would charge to 100% from 3% in about 3-5 hours.
Just to follow up, I picked up a Samsung dock for the Tab 10.1 & used the charging cable from that to test it & my Note 10.1 started charging very quickly. It went from 21% to 56% in about 30 minutes.
I have no idea why the stock cable is so bad with charging, but it is definitely the culprit.
The Tab 10.1 dock is currently on clearance at my local Verizon store for $10. I am going to swing by later & grab the other one they had for a spare.
Cable is a noted problem in other Sammy forums on XDA .

Thanks for the comments.
The tablet has now gone back for repair/replacement.... It's back to the old Hannspad for me until it returns. Oh joy.
I'm not sure the lead is the problem in my case although this is all just speculation on my part. I guess it makes sense in some ways- the charging became intermittent when plugged in which fits with the dodgy lead idea but when it played up it would just sit on whatever percentage it had been on when I plugged it in. Surely a bad lead would result in more uneven results rather than no change in charge (up or down) after hours of AC power?
I'm now kicking myself that I didn't save a screenshot of the behaviour as seen on the graph created by 'Battery Mix'. It was quite literally a straight horizontal line, no charge up and no discharge down. Most odd.
Fingers crossed the tablet will come back fixed. I have a fear it's going to behave itself as soon as it arrives to be tested but hey ho... We shall see. When it returns I'll definitely be investing in a third party lead.
With the original supplied charging cable plugged into the tablet, the device would drop in charge while in use. Meaning, it wasn't drawing enough/any power while in use. Also, it would sit at 22%. Never go any higher. I left it plugged in for 2 days & it never reached higher than 22%. This is on Jellybean. If I switched back to ICS, it would charge just fine.
I found several threads on the web stating exactly the same behavior.
I have since purchased 2 spare cables from Amazon, 2 Samsung branded travel chargers, & a Power+ travel charger, & ALL of them charge the tablet quickly & to 100%.
If I switch back to the supplied cable, it actually drops charge while in use.
I promise you, it is not the tablet.

[Q] slow charge, fast drain, hot batt, jb update

​ Hi guys
I have a galaxy s relay 4g
It took 2 hours of constant usage, to kill the battery from 50 to 0%
Figuring this was normal, I was configuring everytthing while downloading 50apps over wifi
Note phone was on airplane mode, but wifi was on.
Next day I updated from stock ics to stock jb
Turned it on, it was at 91% and after 5 min of usage the phone said it was too hot to charge the bat.
Phone went from 91% charge down to dead with one hour of moderate usage and 2 hour siting idle on airplane mode, wifi on..
It was 46c on batt temp whole time
Charged for 3 hours from pc usb and it gained 3%.
Charged another 3 on wall socket that came with nokia lumia, rated at 1400mA.
Charged 15%
The battery info showed that even though the phone was off, it woke up many times during the night -- IT WAS OFF as in the battery with the 4 white circles on the bottom were showing!
Turned off, removed sdcard, factory reset (left sd out, its still out) i
Came back ok, it syned to google and reinstalled all my apps, then died again
I've tried 2 batteries, and 3 different chargers,
I factory reset the phone too.
Wake lock says the android system used 18% of the battery... other than that I can't see anything obviously wrong
Stock on any device is also resource hungry.... What are the specs of the chargers you are using...certain chargers will not put out the needed amount of ma or volts...which also messes with a Samsung battery overcharge feature
Sent from my SPH-L710 using Tapatalk
Charger 1 is my pc usb port, which charged my other two phones (mytouch q by lg and sammy captivate glide) about 70% as fast as charger 2.
Charger 2 is what came with phone but doesn't appear oem. 5.7v at 600mA
Charger 3 is the oem charger which came with wifes lumia 925 which rates at 5v at 1400mA
Its "charging" in my car now, no sim card, wifi on and connected to a medium strength signal, 0% charged and I wached the voltage steadily decline as I hit refresh in the gsam battery monitor. Started at 3.3v and in a minute was at 3.18v. Still 0%
Car charger is a no name brand (which kept my captivate charged pretty well despite using gps at the end of my 6 hour drive the phone was still at 75%.)
The battery is samsung oem.
The first battery I tried is also samsung oem.
I also have a 5v 1amp charger that will fill both phones between 1 and 2 hours if memory serves, the 1.4 doesn't seem to go any faster as I guess the won draw much if any more than 1 amp.
Given all of the above I'm inclined to think its software or other hardware issue.... phone was sold as "seller refurbished" on ebay, but the description says its just an open box sale of a phone that came back within the first 7 days....and yes I bought a square trade warranty in case some BS like this happened.... but want to try and fix before going that route.
Is there no way to factory reset to the original ics firmware?
I see you also have a relay, once I get this all figured out id love to root and rom mine like you have yours!
I know the newer android roms have more features but are they more or less responsive in general?
Main reason I got a relay instead of another captivate glide is the relay has much more rom development.
And now the red charging led isn't even turning on..... I wonder if its defective.
Shame I can't return it now, the screen has light scratches (was in my pocket while I was working under my carL
And it was sold in like new condition
Grabbed a brand new USB cable plugged the phone into a 5th charger, oem HTC radar, 5v at 1amp
swapped the battery for the 1st one I had.
Appeared to charge fine. Pulled out the charge cord at 50%, plugged it right back in.... the battery charging screen went from about 50% down to 20% in 1 second.
Confused, I left it plugged in and went to bed.
Got up this morning and it was dead again.... while plugged in, while off, not even the charging led was on. switched to the 1.4A charger, still nothing... hit the home button a couple times and the thing woke up into the battery charging screen (it ignored the power button the whole time)
The gsam screen was even more interesting:
it doesn't show much but the line graph showed a rapid decline from 20% down to almost 0 from some short time before 3 am, then
3 hours from 3am to 6am, the charge went from near 0 to 50%, and then in half the time back down to near 0.
The temp graph wasn't a line, but fragments of one
does Gsam show the amperage of the draw or charge on yours? its only ever given my the voltage of the battery and shows 1mA on the bottom of the battery,
ebay seller says clean the charge port with alcohol.... not sure why someone should need to do that on a "like new" phone but I'll have to try and find something tiny to shove a paper towel in there with..... that would account for the not charging but not for the high drain.... could thins thing have a short someplace?
sounds to me like a defective device. the fact that you did a factory reset and it's still not charging even with it turned off is probably the biggest sign there. it can't be any apps you've installed because you wiped them all off. i think you've gone way above what should be normally expected of a customer in terms of troubleshooting your device. hairline scratches on the phone are fine. you should still be able to return/exchange it IMHO. especially with the squaretrade thing.
yes, it's possible to flash back to stock ICS but if it's not working with the factory rom (whether ics or jb) the phone obviously has issues.
i just bought mine a couple weeks ago too, though not over ebay. i found a local tmobile "authorized" store (advertising on craigslist) that was selling stuff with similar description - open item or customer purchased and returned within a week. i have used mine on all sorts of chargers without issue: a motorola dual-usb rated at 750ma in the car, a monoprice 2.1a charger built into the 10-outlet power strip at my desk, 2 different laptop usb ports, and a samsung wall charger rated at i think 1.8a which came with my wife's galaxy tab 2. i never ran stock rom for more than about a day or so, just to verify proper operation of the phone, and now i run cyanogenmod11. i can go all day on a charge with what i consider medium to semi-heavy usage, which i think is great.
for example, yesterday i unplugged at about 9am after an overnight charge (with the phone on - i almost never turn it off because i have to be able to receive on-call alert emails from work). i got the day started in the attic installing radiant barrier (so it was rather hot). i had the phone in my pocket streaming a shoutcast station over wifi for probably about 4 hours. later, i watched a 30 minute show on netflix (also wifi), played some wordfeud, surfed the net a bit, watched some youtube videos on fixing my weed eater, did a few emails for work, probably 20-30 texts and maybe 10 minutes worth of phone calls. by 11pm i was still around 30% charge remaining. at no time did i plug in my phone during the day.
i have an extended battery on its way from china, so i expect to be able to go 2 full days on a charge with similar usage. and the thicker back plate will make it easier to hold, since i have such long fingers.
tl;dr - you got a bad phone. exchange it.
