Glad to hear all the great battery life everyone has been getting. I agree that qcell is quality and is a major improvement to our phones even with extremely heavy usage it barely takes a dip in battery life compared to stock.
[Samsung Epic 4G Touch] RCOVA:
Well i just ordered mine. I had incredicell which was great but its performance ran down quickly. And then I got trexcell and that one just sucked, so hopefully this one is the beast I've been looking for. :D

I tried comparing two oem batteries to a trexcell and the oems were about 1-2mm thicker. I think I might have tried to put them in the extended case and it wouldn't snap shut.
[Samsung Epic 4G Touch] brooksyx:
Bummer. I just ordered a cheap extended battery and cover and want to wire to OEM batteries together in a parallel. Maybe the back cover can be trimmed a bit to fit 2x OEM batteries?

Got my battery today, black cover matches the phone nicely. Came with a 60 percent charge and 3 hours later sitting at 50 percent. Can't wait to break this battery in to see how long it will last.

Just ordered mine today. Anyone know of some cases that will fit?
[Samsung Epic 4G Touch] brooksyx:
From my understanding unless you want to cut the back out of a case the only one that will fit is the trexcell tpu one.

Just got mine in the mail from amazon today (ordered yesterday morning, here today!)

Popped battery in at 3:45 EST and it came with 63% batt life. Gonna turn everything on to drain the battery. Will report back later.

13% left with heavy usage and its only 11:13. cant wait to charge this!

first discharge
[Samsung Epic 4G Touch] jtsv:
Not that one but I did get (2) 3800 mAh batteries from ebay after the seller had a pricing error. Only issue is I've yet to find a wall charge so I have to charge batt's in phone and keep the spare charged. I've like the larger case (fit's in hand easier) but have added little anti slip strips because the plastic is too smooth and slips easily.
[Samsung Epic 4G Touch] eddie3130:
I just recieved mine today an im definetly loving the shape of it.. It sits perfect now in my hand. I can grip the batery hump with my fingers perfect. Now to see if i can mod the car dock so it can fit.. Hhhmmmm

Wow!. Ive been using this battery for the last few days and i realy am impresed. I used the phone yester alday with moderate use. Went to comic con an took pics. Then went to see spiderman. Got home at 1am an stil had like 30-35% left.. The day before that i had 13% left with 23 plus hours off the charger.

And a extra plus is great that this phone seems to read the extended batery correctly. Not like my Old droidx that would drop quick then hang at 5% for hours. Running Mijjz latest Goodness Blend

Question for you guys... How are you charging this battery? I have the external charger from amazon.. Stuck it on there but it's only charging my battery to 95%..even after hours once it said charge complete

5% may not seem much but it is on this battery..I had 9 hrs screen on time from 95 to 0..could have gotten way more

Another comment* The battery is not even bad size wise to me.. My phone feels better in my hand & not feeling like I'm going to drop it constantly from being so light(plus I have big hands) .. Threw a screen protector on it &feels good enough not to use my case for it

I have had this battery for about 4 days and it just never runs out. I average 4 hours screen on, 3 hours talk time and tons of Pandora. I used 2 batteries changing them out at lunch everyday until now. This thing is at 30% every night when my day is done.
[Samsung Epic 4G Touch] Beremat:
Is it apparent yet whether or not these batteries die like the Trexcells?
[Samsung Epic 4G Touch] revamper:
Yes. Every single Qcell will last forever.

I need to invest in one of these with the trexcell tpu case already.

Broke down and finally bought one with the trexcell tpu case from amazon. Should be here Tuesday!
[Samsung Epic 4G Touch] brooksyx:
So far I am not to impressed with the battery life of this thing yet. Not getting what everyone else seems to be getting. Will wait a few more days to let the battery settle in though before I pass to much judgement.
[Samsung Epic 4G Touch] pgg285:
Just got these myself. Battery seems decent so far; only minor complaint about the case is that it blocks the USB port ever so slightly. Plus, it'd be nice if there were cutouts for the rocker buttons and the power button. Still, it's nice to finally have a case for my baby. :)
[Samsung Epic 4G Touch] GiantJay:
So how is this battery holding up for the people that have had it a few months?
[Samsung Epic 4G Touch] saeba:
I've had mine for about 2 months.... The big change I saw was with the ICS update. I'm now holding steady at about 25 hours of battery time. Again, I use mine primarily for work email and calendar.
[Samsung Epic 4G Touch] GiantJay:
I was going to order this but I can't fine it anywhere online for sale. I'm thinking of getting a Gorilla Gadgets 3500mah or there is a lexmar 2500 that I can get at best buy for $21, but there is no reviews anywhere online for the lexmar.

Thats still impressive compared to what you could get on stock 1800 mah. Is your signal steady at 3g or 4g, that makes a big difference as well.

I have this battery. After the recent fb app update. I noticed my battery was draining really fast. Turned off Auto update for that 1 app and all is back to normal. I average 6-7 hours screen on time at 70% brightness. Check recently updated apps. Check apps and services that sync. Many apps like fb default back to battery hogging settings when updated.

edit: it doesn't seem to matter with the fb app what the refresh time is. If Auto update is enabled it sucks battery. So I keep my refresh interval to never and just manually refresh when I check it from time to time
[Samsung Epic 4G Touch] revamper:
Could be due to a 3rd party charger. The lower the output, the better for the battery.

I wasnt impressed with this battery at all so I ended up returning it to amazon after about a week and a half. But I also sold my epic touch as well. In the process of switching to the galaxy nexus with straight talk service, think I will be much happier with that phone and service over my crappy virgin mobile service.
[Samsung Epic 4G Touch] bluedevils2003:
Did you check youtube? I always check youtube look at buyers reviews
[Samsung Epic 4G Touch] eddie3130:
Same here. Started getting an hour or maybe a bit more over the stock one after less then a month of use. Id rather enjoy the slim factor of my phone so i keep it as a spare in my car instead.
[Samsung Epic 4G Touch] Trailsend:
I note that the Amazon website mentions that the Qcell takes more time to fully charge than a regular battery.

"To charge the extended capacity, please leave battery charge for 2-3 hours after 100% charge reached."

"All Extended Batteries require 5-6 full charge / full discharge cycles for maximum capacity. Rare occasion of 8-10 full charge / full discharge cycle is required for maximum capacity"

If this is what everyone is doing and the capacity is still falling after one month of use... then the battery is just not worth the money.

It makes me wonder how they constructed the battery pack.
[Samsung Epic 4G Touch] billfog:
Ok, I just don’t get it.

I read here that the batteries need to be conditioned buy a full discharge and a full recharge several times.

I just ordered the qcell 4100ma battery and even qcell says to condition the battery that way.*

This contradicts everything else I have ever read about the proper care of a lithium ion battery to promote long life.

I will be getting my new battery in*tomorrowand am not sure how to proceed.

Any feedback would be very helpful. Thanks
[Samsung Epic 4G Touch] revamper:
I've done full discharges and I've had good results.
[Samsung Epic 4G Touch] billfog:
Well I will do what you guys are doing. Most of the posts seem to report favorable results from "conditioning" the battery and manufacturer recommends it. I would be foolish to ignore your real results and the manufacturer's instructions.

I still don't get it though. I googled "lithium ion battery care" and just about every traditional authority says that deep discharges and heat are total life killers to all lithium ion batteries. How could they be so wrong?

Drives me nuts when I don't know the whys.
[Samsung Epic 4G Touch] revamper:
I think it's because, for example, 5% on an extended battery is still holding much more charge than 5% on an OEM battery, making it less deep of a discharge.
[Samsung Epic 4G Touch] Trailsend:
Rather than a "conditioning" of the battery it is probably setting the battery chip to the min/max capacity of the battery.

It must be using an average rather than a single calibration.
[Samsung Epic 4G Touch] Nannuq:
After just over 30 days using this battery I am still getting amazing results. I wake up every day at 5:30 am and take the phone off the charger. I go to bed every night between 10 pm and midnight. I never plug it in anymore during the day. During the weekdays I average 5 hours of screen on time per day and 3 hours of talk time. I leave everything sync'd but the FB app, which seems to drain everything if left to update on it's own for me at least so I set it to "Never". At the end of the day I am generally between 10% - 15% remaining. During the weekends I take it off at the same time and put it back on at the same time. However, Since I work so much less on the weekends I still end up getting around 3 hours screen on time and 1 hour of talk time with around 40% of the battery remaining at bedtime.

I haven't taken any screen shots of my phone because personally I don't care if anyone believes me or not. I am simply posting my results so that they might give insight into a positive example of the battery. As with any phone things can vary based on your set up and Faulty batteries do happen so if you are getting less that this I would RMA it for an exchange if possible. I will update if my battery starts to die.

When I initially got the battery I put it in and charged it to full then used the phone until it died. Then charged it to full and did this for 1 week. When the phone died during the day and I still needed it I swapped back to the stock battery until Bedtime. After the 1st week I stopped doing this. It was probably over kill and unnecessary but I wouldn't be giving an objective review if I didn't include everything that may have lead up to my current results.

Hope this helps.

In addition I listen to a lot of Pandora and Audible during the day, everyday. The screen is off during these times so it's just Bluetooth and data or Bluetooth and just streaming from the device without data. So the device isn't just sitting there doing nothing I am constantly using this and on the weekends I listen to more audio than during the weekdays. These aren't reflected in the battery usage within android for me, I do however have a 3rd party app for measuring battery usage by apps and Pandora and or audible account for around 20% of my battery drain per day with around 8 - 10 hours a day listening.
[Samsung Epic 4G Touch] horrell702:
i ordered the trexcell 3800mah battery for the e4gt n im amazed at that alone. i can only imagine how long the 4100 would last. i get 2 days of heavy use with the trexcell. lol

[Samsung Epic 4G Touch] rdx321:
This battery is huge. How is it running for you guys that have had it for a while now?

How long does it take to charge?
[Samsung Epic 4G Touch] Nannuq:
5-6 hours from dead for me with a 1A charger
[Samsung Epic 4G Touch] billfog:
I have had the battery for 3 weeks now.

My usage is what I would call moderate. I surf the web, read emails, make a lotta calls, use skype video and occasionally use telenav.

I never turn off the wifi but sometimes use the 3rg. (data is always on) I never turn off the GPS and I let my email update often. I dont use any tweaks or programs to conserve battery life in any way.

With the oem battery I would get about 4-5 hours use before I HAD to plug it in. Now I get about 18 hours with this battery and its usually at about 15%.

I dont know how long it takes to charge because I charge it when I am sleeping but I only sleep about 6 hours and its always fully charged when I wake.

I am very happy with it and although I have no idea how long it will last I wouldnt have any complaint if I had to replace it every 6 months since it is under 10 bucks.

The size of the battery actually makes it easier for me to hold the phone and when I lay it down it keeps the camera lens off the surface it is setting on.

The wife has the same phone as I do and she likes the way it feels and can hang on to it easier too.

Hope they sell this battery on amazon again and I hope this was useful info.
