This is Ksmullins, posting this for a team member. Just an update on what the battery can do with an Epic Touch.

"I just finished my test for the Mugen 1950mah (video below), and I have noticed in past chargings that it was faster by a good 15% from when I normally plug in and remove. So I figured it must be because I hit a great UV at 200mhz, -125mv on core and internal, which allows the battery to charge faster given the fact that when charging the phone stays at 200mhz. So providing the cpu with less power will provide the battery more power while charging. IIll be providing proof of this soon."

Also charging with a USB charger for an iPad, 2A, will charge the battery pretty damned fast too.
i could've sworn this was common sense.
I get a day and a half out of my battery anyway, why make it this slow.
What's the general consensus now regarding when to charge the battery...keep it charged up all the time or let it drain down low (15% or less) before charging??
(I have DAFS, just so much conflicting info)
I say 15 - 20% charge it. But really I wouldnt worry about it.

guys i made a huge discover! the lighter your car is, the faster it can get to 60!
It is interesting to learn that a 2A charger will actually charge the battery more quickly. Given the heat generated by these devices when being used and during a charge cycle, I was almost certain that the E4GT would include both current and heat restrictions to prevent this this from physically burning up. I recall my TouchPro being unable to tether and charge at the same time... it would get too hot and just stop charging as a safety restriction.
I've had both my Epic and Epic Touch reach and sustain 52C (125F) while charging (1A) and playing Tiny Tower. Increasing the current can only raise this peak temperature, which is nuts considering that an internal battery temp of 125F results in a very, very hot back cover. The Epic Touch screen also gets hot, almost burning to the touch. This can't be good for longevity lol

This phone is only lasting me about 8 hours before my battery will die. What can I do to help out my battery?
Sent from my SPH-D710 using XDA App
download an app call battery calibration, then after a full night of charging, go to that app and calibrate with the charger plug still in, after its done reboot phone and take it off the charger. drain the battery until it shuts off by itself. charge it back up while its off. then continue to use as normal. wait a couple days to see if the battery gets any better. my phone doesnt last too long either, im thinking of replacing the battery to see if thats the problem
Try removing some apps, that worked for me there was some apps that were sucking up my battery.

slap on a extended battery!
Kiss it three times, say two Hail Mary's and toss it over your left shoulder.
No seriously, battery life is very dependent on many things, and your statement doesn't come close to providing enough information for anyone to give you any real help. At minimum you need to provide the following during your 8 hours ...
- Total Display on time
- Brightness setting
- What you have auto syncing and how often
- Average signal strength
- Usage pattern (web browsing, calls, streaming video, etc.)
- Widgets on your home screens
- Screenshots of your battery usage and graph
My phone will also last around 8 hours if im constantly using it.
Thanks everyone for the responses. I will try out all the advice.

With moderate use, I get about 20 hours. With heavy use I get about 10-12. It's still enough to get me through the day
Love this phone!

Disclaimer: This is not not supposed to be another battery life issues thread.
So! I have been noticing that my nexus has been showing a slight increase in available charge without being plugged in. I never noticed this occurring on my thunderbolt and my old touch never made it that far along so I can't compare it to that.
I have calibrated my battery 3 times since I bought it and have been swapping ROMs. I am currently running Android Revolution 2.1.2.
Does anyone know what might be happening?

It happens. It's normal. Sometimes you demand too much of your battery. It heats up losing a little voltage but gains a little back when it cools down. Another epic reason uv'ing is valuable. Lower heat. It also extends longevity of electronics and your battery.
Sent from my Galaxy Nexus using xda premium
Its just voltage being under load and then being relaxed so it pops up a bit. Some phones exhibit this and some don't. It all depends on the type of battery driver used. Some like the max17040 use voltage to determine SOC and some use strictly coulomb counting which don't have this bounce effect. Most Samsung phones use the max17xxx fuel gauge using voltage, and most HTC phones use ds2784 and similar which just counts current, so no bounce.

Thanks guys, I had a feeling it was something like this. Thanks for all the info, especially the stuff about the drivers. I find it fascinating how something like the way a charge is measured can cause effects like this.
Good day everyone, I've been using CM9 for awhile now and its been an awesome ride so far. Everythings been working almost perfectly. Recently, my batteries(stock one) percentage level's been Jumping up and down...a lot. For instance, I woke up to it (while off) having 100% on the indicator, turned it on, and it dropped to 51%, re-booted it to see if that'd help but it dropped again to 12%. This kindof things been happening for awhile and still with Alpha 2. Should I just get a replacement from sprint? Or is there a workaround.
Also, Music's apparently been taking up to as much as 40% of my battery usage even though If don't even have it activated at the moment. I've tried deleting the apk but it appears com.android..., I may just be being a noob, but any help?

Jump" is typical when you don't power off completely and then power back on no work around other than turn it off leave the battery out for like 3 or 4 minutes and power it back up

Apparently calibrating the battery according to some Android Engineer does nothing. The percentage you have left is directly related to the voltage of the battery. So if you are at 3.95 volts, that roughly corresponds to 50% with a range of 3.7 to 4.2 Volts on the battery. What the OP saw is the bbb...battery boot bug. If you are rebooting and you are lower than 70% do it while plugged into something. If it does happen as Biggie stated, simply remove the battery for a couple of minutes and reboot. It is a false report to the phone.
This has almost always been a issue for me when I flash anything new. It stays that way for until I deplete the battery, connect and leave connected til 100%, deplete the battery and follow the same process for about 3 full cycles and then all is well! Leaving battery out for a breather sometimes helps but I installed an app that has a widget and it keeps the regulating kinda monitered so I can be a little more at ease. Will post directly after this. But I also noticed that there have been times when the readout was a very low battery red [but I knew couldn't be true] and after I put it in airplane mode and didn't bother it for 5-10 minutes when I looked back again, battery would be yellow almost back to showing good and my battery stats show the levels increased. I think cm9 can't handle too much at one time anyways
Edit: that app I think is called battery info. Its pretty simple =) hope it helps! L8rz
Edit2: that app is listed in market as battery widget not battery info

Just got my s3 like a week or so. I made a mistake and not charge it initially (thought it was a myth). I used my battery all the way to 17%. Now my battery only average up to 2 hours screen on. My sister who also got the phone as the same time has about right hour screen on time. Did I screw up or it's just my battery being defective

Well, when I'm in door, I use low brightness most of the time. Only when I'm outside I would use auto brightness. Since I'm in wifi zone most of the time, yes I do have wifi on. I mostly use my phone for twitter, web browsing, and youtube, nothing heavy like gaming or benchmark.
Hard to say if its defective but I've definitely seen a lot better battery. It might not hurt to try and get a new one.

you should calibrate your battery a couple times once you get the phone. do it a couple times and it will fix itself. also check all your syncing settings. this phone will deplete a battery in 5-6 hours if fully charged and phone brightness is up all the way while watching videos.
Calibrating batteries is a myth from the days of older battery technology. Draining your battery to 0 on purpose is actually killing your battery faster because you just used up one cycle.

There's a bug on stock that makes cell standby much higher than it really is. So I wouldn't worry too much about that.
Also, Google Chrome is a huge battery killer for some reason. Consider switching to a different browser?
Still having the original battery in my vibrant and getting 8-9 hour charges while killing the battery 100% and charging it up once a week does nothing? Same thing for my g2x. I get about 10-11 hours on the thing daily original battery as well. If anything and you're not rooted to delete battery stats, its a good thing to do a couple times. I don't think I have hurt the battery at all, and if anything they still last very long...

I bought the Chichitec 2500mAh extended battery pack and they work very well. I get on average a minimum of 4hr screen on with lowest brightness as oppose to 2hrs and change with the stock. I also use jucedefender and I rarely talk on the phone. I would recommend them.

I have that one, it isn't bad, but it isn't great either.
Typical Chinese quality (Samsung is spelled Sanmsung and Galaxy is spelled Galyxa when you actually get it).
Battery life is, well, I dunno. It's hard to say. My phone was at 57% charge, I turned on the extended case and without any use it charged my phone back to 100% no problem but the extended battery was pretty much dead. I'm sure it works better when both the phone and extended are charged to 100%. The AC/DC converter inside the case is VERY inefficient and gets VERY hot. Don't even bother attempting to charge the extended battery while the phone is in it, I'm suspecting it will catch fire or melt lol...
I like how it has a power button and the kick stand works. The case is very sung and everything lines up properly so for build quality I give it a 10.
The USB port pass through is CHARGE ONLY, data pins are missing so it kinda sucks if you use OTG devices or need to plug it into the PC to transfer files etc. But all in all you get what you pay for.
My friend has the Hyperion 4200mah with NFC. It works excellent, double the battery life. He usually gets 3-4 days with normal use out of the phone without charging (but that depends on person to person).
Here are some of my hyperion 4200mah stats
