I'm currently on the CM7 ROM, I have juice defender and done all the minor tweaks as far as disabling wireless network location, turn off the wifi and GPS, and an app killer. I still only manage at max 9 hours before my phone tells me to recharge.
If your getting great battery life, help me and others by sharing your tips here.

Best tip is to stay on wifi as much as possible. I got 3 days on wifi and about 4 hours use.

I turn data off when im not using the internet and when I'm just listening to musc I just put my phone in airplane mode
Yeah, I need some help too. I get about a day and a half with no use at all, and about 10 hours with minimal use. 4 hours with real world usage... I can't deal with this. Could it be the battery? It performs like a 1 year old, used, refurb battery came with a stock phone!

Have you configured the battery since flashing the rom?
I get decent enough battery life, with light usage I can go about 36 hours w/o a charge but on my heavy usage days I usually have to use the car charger a few times a day.

all of these... biggest one is to turn off data when the phone is in your pocket. use wifi when u can, avoid using 4g unless plugged in, configure the battery in recovery (i've actually notice that this helps less than anything else for me), and finally: get an extended battery. it's worth the extra hours u can squeeze out of it. don't expect more than 4-5 hours screen on time with any rom/kernel/modem combo with a stock battery.

Yeah I also did that wipe battery stats at recovery.
I just thought maybe my expectations were too high, although it seems as if my battery drains drop pretty fast.
I would say about -10% battery drop every hour, just checking the time and send/receive text messages. Occasionally I surf the Web on the phone when on break at work. Other than that the phone is in my pocket, and after my 9 hour workday my phone demands the charger.
This is with the stock battery, so I guess this is normal unless I'm using the extended battery?

u could also run a kernel that allows for over (under) clocking/undervolting. that helps some, too
get the duricell portable battery extender, add milliamps to your arsinal in one way or another with extended batterys or whatever, if you call sprint and complain loudly and dickly they will rebate you the cost that u spend on a new battery or batt extender whatever... that being said all the above options work great, u can also use night mode on chainfire 3d to save battery, or perhaps half your pixel rate, or perhapes turn off some colors (havent seen an app to do this yet) and reset your battery memory in cwm, kill ur batt, charg while off, then cycle again like that. (theres an app for that) if your not rooted, root your phone. if you dont want to root your phone, cycle ur battery the old fasion way or pop it into a rooted phone and do it.
I used to get really poor battery life (due to my phone not sleeping as evidenced by Spare Parts app). I rooted, used Titanium Backup to freeze various apps, and got an Zboost antenna booster for the office and called Sprint who sent me an Airave for the house. I wiped battery stats and cleared my Dalvic cache and the thing the finally got me right was finding out the Amazon MP3 app was still logged in though not running. Once I made sure I was logged out of that and Lattitude (Google Map feature) and Facebook, I haven't had any problem with a sleeping phone. Stock Froyo, standard battery, but rooted. When they say a bad app keeps your phone from sleeping I think they mean an app that requires log in...although this does not seem to be a problem if you stay logged in from a browser, only from an app!

You may be shooting yourself in the foot with some of those things. App killers aren't that useful on Gingerbread since they keep killing apps that just reload on their own, and every time the reload it uses power. Just because an app is loaded doesn't mean it is running. Try letting the system take care of it. Juice Defender may help a little but it keeps shutting down data and starting it up, which means you don't get as much usefulness out of the phone and may waste power in some circumstances.
See what you have set to sync. Turn off any autosyncs you don't need, like weather screens, facebook, etc. If at all possible set them to only sync when you open the program.
I use the exchange option for gmail using the stock samsung app, which gives me push email but doesn't have to keep polling the server. I don't know if that makes a difference compared to imap, but it works well for me. don't think you have that option in CM7.
Wifi is a much more efficient way transfer data than 3G, use it whenever you can, and set it to never sleep. Otherwise the 3G radio keeps starting up again and wasting battery.
You can freeze the DRM stuff if you don't use it. I don't know if it really makes a difference but everyone thinks it does, so I do it.
Having a black wallpaper helps a little because on a AMOLED screen a black pixel uses no power.
The biggest battery killer is being in a bad signal area. If you always have 0 or 1 bars then your phone is going to always be draining the battery trying to find a good cell. In that case Roam Control may help you.
That's about all I do, and with the latest Stock gingerbread EH17 and EI22 I'm sitting with about 40 to 50% left after 12 hours, that's with light to moderate use.
I've been through the ringer with this. I'm pretty comfortable now, routinely managing to have 33% of battery left after 12hrs w/3g always on, sync always on, intermittent music listening, 2.5-3hrs of gaming and general "screen on" time (auto brightness), 1.1 GHz OC, no undervolting, and GPS always on. Here's what I'd suggest:
Flash a ROM w/ NO CIQ (thanks k0nane!) - In addition to being a leech on your privacy it's a leech on your battery. It's old news to long-time Epic owners at this point, but ditching CIQ improves battery life and overall responsiveness of the Epic. A popular stable Froyo ROM for this is SFR 1.2.
Minimize always-running services - Long press your homescreen, select "shortcuts," select "settings," and select "running services." Tap this to see what's running ongoing services (not apps) your phone is running. All of these are drawing current to stay in RAM. Things like Juice Defender, Tasker, and others show up here and draw power in doing so. JD and Tasker especially can drain a lot because they perform constant tasks as well. Uninstall them and let your phone manage itself.
The same goes for task managers and app-stoppers - Froyo and above does this fine on it's own
Freeze/Uninstall system services you don't use - This includes things like Sprint voicemail, the "Email" app, and the "SprintAndroidExtension.apk," and SNS services. You'll most likely find these on the "Running Services Page" as well. You can Titanium Backup to uninstall them, but I recommend the SDX Stock App Remover as that can restore them (TB can't reliably). TB can freeze these as well, which accomplishes basically the same thing. SNS is connected to Facebook, so if you use that a lot you might want to keep it. DRM services can also be removed, but may cause problems reading the SD card. I stay away from it.
Use Spare Parts to monitor wakelock and CPU usage - If you notice something giving you persistent trouble, shut it down. This is time-consuming, but you'll get a good feel for what apps are out there to accomplish similar tasks and which one best suits your needs.
Uninstall apps you don't use - Next time you wipe and flash a new ROM, reinstall or restore backed up apps as you need to use them and not all at once. You may find you don't need quite a few of them, allowing you to keep more space open on your phone and requiring less current to maintain them
Don't charge the battery overnight - most phones can reach capacity in 2-4 hours depending on charge level. Beyond that, holding at or around fully charged will degrade the battery by denying it the ability to release the stored energy. I charge mine in the evening a few hours before bed and top it off in the morning before leaving for work.
Get an 1800mAh battery sold for the Epic Touch - this is what moved me form "getting by" to "definitely comfortable." For around $25 (incl shipping) on ebay, I've gotten a new lease on my Epic's life. It may seem like cheating to bring in a new battery, but it makes a lot of difference WITHOUT adding more bulge to your phone (makes it a tad heavier though).
Hope this helps. Remember, of course, that what works for one phone won't necessarily work for another. Despite being the same model, minor imperfections in silicone can create individual temperaments for each phone.
I as always trying to make my battery last by stopping this and uninstalling that. Then I thought; why did I buy this phone with all of these capabilities to turn them all off
So, something like the "Hyperion Sprint Samsung Epic Touch 4G 2 x Battery + Charger" (too "young" to post a direct link)
Would fit in/work with the Epic 4G (without needing a new cover)? Even though its for the Touch?
Lol, I've been doing many of the suggestions across the board, and have gotten much better results. But I'm still not "comfortable" with my battery strength, especially when I'm unable to charge my phone all day...
Looking into your running services is a big one. week ago my battery life greatly decreased. I kept seeing market update pending and it wouldnt go away. Never update never go away. I manually updated the market and the battery is back to wonderful. It drops 2-3% at night off charger. Thats about 8 hours.
A sticky with all the main running services and which ones you can stop would be wonderful. I have sns services running. I think i can stop it but not positive. I also have sanservice running supposedly some type of samsung update. Its not doing anything but its been running for 2 days. No negative effect on battery(that i notice) but its running. Also make sure you turn location off. Ive also noticed that even when you back out of google maps its still in running services. A restart fixes that but thats annoying.

SNSservice is a Facebook and Feeds and Updates Widget service. ALWAYS stop it. It does not matter to Facebook, even if you use it, but if you remove the Feeds and Updates Widget on one of your screens, that service continues to search for it and will kill your battery in a matter of hours (it starts a "restarting" loop). Either leave the widget on or kill this service after every reboot or if you are rooted, freeze it along with DRM service.
My other battery tips are to log out or sign out of every app such as Lattitude, Facebook, Amazon MP3 (it's ok to use them, but don't just back/exit out, actually sign out of them so you have to log back in next time). Apparently, staying signed in causes your phone to not sleep and you can't find what is causing it (i.e. you can't see it "running" anywhere...people call it a misbehaving app, and you would have to delete apps one at a time to find it by trial and error).
So I think by now everyone has realized the battery life on our A100's is mediocre. I've actually been pretty content with the usage I get out of mine. What I'm not so thrilled about though is the idle usage. I'll leave for work in the morning with my A100 at / above 90% battery and come home after 6pm with it completely dead. I have wifi set to turn off when the screen does, any app I have that has a sync option is set to 6+ hours, and I've stopped using live wallpapers. Every other electronic device I have can usually last a full day when not in use(my old netbook gets 3 hours of use on battery but 2 days while sleeping).
I've started looking into the "bloat" / OEM apps installed by Acer. Nidus, sync, socialjogger etc... My main questions are; what can be removed, what can I live without or would be better of with a 3rd party app, and which Acer apps can possibly be causing the idle/sleep battery drain? This thing should still last a full day while sleeping, shouldn't it?
Any suggestions? Anyone else have this issue? Thanks!
You could try using Bloat Freezer to freeze apps. I have alot of the acer stuff frozen, and with it in standby, easily goes a day. Things like socialjogger, acer init, etc.
These are the apps I've completely removed from system apps, made a backup of course..
AcerClockwidget.apk&odex
Agendawidget.apk&odex
Aupeo.apk
Clearfi.apk
DTG.apk
LinkToFacebook.apk&odex
MusicA.apk&odex
MyLocationWidget.apk&odex
NemoPlayer.apk
Planner.apk
SocialJogger.apk
Solitaire.apk
Xt9.apk
You can also remove appinapp butyou will loose the games multimedia app I use that so kept it.
Battery life hasn't been that bad on mine. I expected worse, I just picked mine up last week and after reading reading reviews I expected worse.

WOW! I can use mine all off and on all day and don't have a problem. There has got to be an app that you are using that is destroying your battery when idle. If I don't use my tablet all day, it will last 2 full days (with wifi kept on).
That's what I was thinking. I get a decent amount of usage from it; it's when I'm not using it is when I feel like it drains the most.
I started freezing apps last night and let it charge overnight. I've still got to go through my apps and remove a few I don't use, and check to make sure they're not syncing too often. Do you all leave your gps and wifi on all of the time or have them shut off while the tablet sleeps?

My settings are to never turn WiFi off and I always leave sync on; I like getting notifications and app updates. I have a weather app that updates every hour and Pulse news that updates every 4 hours.
I also always leave my GPS on, but there aren't many apps that use it while it is not in focus, so I rarely ever see GPS pop up on my battery usage list.
I do not use a live wallpaper.
I found that with wifi on, my tablet drains about 1.5% per hour when idle.

I suggest other than setting wifi to turn off when screen is off is to use a wifi toggle widget. You really never know what happens when the screen is off if your wifi is really turning off. Wish it was built in to the quick launch though like some Honeycomb tablet.
You can also use setcpu to setup profiles so that when the screen is off the processor stays at a slower speed rather than jumping into high gear when something wakes it up to sync. I've been able to go days without having to recharge (but I only use it for reading books, listening to the music I have on google music and play order and chaos every once in a while). I havn't touched my a100 in about 4 days and its sitting at 62% battery power.
Sent from my MB860 using XDA App
here is my usage, I never turn off wifi no profiles
I don't necessarily think you need to remove any of the stock app. My wifi is set to turn off when screen is off, GPS off unless I need it (apps like facebook will use it when you open it since it tries to get your location for checking in even if you're not checking in). Gmail is left at default but other mail is set to never (I just manually sync it when I open it).
If you wanna go a step further, you can install a wifi on/off widget to completely turn it off just incase an app is trying to use wifi.
With my setting my battery drains about 1-1.5% an hour when screen is off. IMO the screen is what uses the most battery. However though after conditioning the battery for 3 cycles it's been lasting longer.
I was just about ready to return / exchange my a100 so I did a factory reset on it. Lost track of time and forgot to, so I just decided to boot it back up and play with it. Left it alone at around 70% yesterday afternoon, came back home at 7pm today and to my surprise it was at 40% battery remaining. Must've been an app or setting I had that was killing it.
Probably end up hanging onto this awhile longer. Great tablet for the money!

Also can freezing apps brick your tab as well? Or does it defrost itself after boot?

I think with the 1gb ram on our device there shouldnt be a need to freeze any app and it doesnt defrost itself on reboot. Atleast it shouldnt.
Also I found for the most part if an app can be deleted it will let you delete it by dragging the app icon in the upper right in the app drawer. This is probably the safest way to delete rather than doing it in root explorer or TU.
This might be a dumb question but is it possible you have wifi issue that i've had on 2 a100s which will prob cause it to use more battery as its trying to work harder locking on.
It seems for the moment my battery issue was resolved with a factory reset. I have nearly the same apps on it now as before and my a100 hasn't been dying overnight. Don't believe I've frozen anything this time around either.
I don't think ram has a whole lot to do with it. I just figured some of these apps were starting themselves or syncing often, causing the battery drain.

Do you have a lot of widgets that requires syncing like youtube, twitter, weather, facebook? Those are the apps you probably what to check. OR you can just turn off wifi if youre not surfing or streaming.
Here's mine with wifi turned off. It was at 89 but I had to turn on wifi so I can find a screen capture app in the market. I have lots of apps including facebook, twitter, weather widget, which cant sync cause the wifi is off. Have not removed any stock app. I know this doesn't really answer what you asked but I'm just thinking something else might be wrong other than apps. Maybe its your battery not holding correct charge. Have you tried calibrating the battery?
I tried calibrating the battery the first time around. This time (after the reset) I haven't done anything special and have so far been getting 2 days of idle/light use before needing a charge. Satisfied so far. I was mainly concerned that I wouldn't be able to go on a trip without it needing a charge while sitting in my bag for a day without use.

Ok well let me just start off by saying. I LOVE this forum and the helpful and friendly people. Lemme give ya a run down on what I'm rockin' on this marvelous piece of technology.
Bootloader Unlocked - Check
Root - Check
R800x Timescape UK Firmware ROM - Check
V6 Supercharger - Check (Could use help making it start on boot.)
Better Battery Stats - Check (Could also use some more help since I'm a noob XD. More below!)
Battery Life - QUESTIONABLE
And here lies my problem here. Ever since I switched to the UK Firmware from Verizon's I've noticed the phones true potential and love the UK Firmware. However what is up with the terrible battery life? I've tried everything... It seems to DRAIN 1% every 5 minutes when I'm at school!!
BetterBatteryStats talks about wakelocks. I get this one sometimes called UID and have no idea what it is, and have looked for a solution but found never in ACTUAL terms I could understand. Also there's a blue bar and a red bar on the stats for those. Can someone please tell me the difference between them?
I've deleted Juice Defender as some people said it actually DRAINS your battery more. I've also heard this phone lasts sometimes 3-4 days on a FULL CHARGE?! I'd like that please! :O
Well when I'm at school I put my phones Brightness to 30%, Vibrate, and off WiFi.
I listen to Music and that seems to drain the battery ALOT more than I think it should.
Also, when playing Asphalt 6 HD, I was at 57% battery, I played for maybe under 10 minutes and had 44% LEFT!!! That's TERRIBLE!
Can someone please tell me how to make my battery last like others have it?
I also have 2X Battery installed but disabled and only showing my battery % on my taskbar up top.
Thanks again in advance for your answers and I hope I have provided enough info. THANKS!
If u don't use it during school then power it off. Also kill some tasks so your phone won't work hard and kill morw battery life.

I do use it during school. Sometimes as a Calculator, to text my family or if they have to call me in case of emergencies. I also game on it at lunch or listen to music when on a free period so...
And I do kill tasks all the time. It seems to just open themselves back up. Also I played Dead Space last night with 100% charge for maybe about an hour or 2 and the damn battery drained down to 55%!!!
I was on WiFi as well...

You honestly can't expect a game such as that to run on this phone and merely sip at the battery's juice. The percentage remaining when coming out of an intensive task, such as watching video or playing a game, isn't entirely accurate. Check the battery again after a few minutes of idle time, and it should be a little higher than it was before.
I use an app called Battery Defender. It's very easy to set up, and the main option is to kill the 3G data while the screen is off. You're still able to receive calls and texts and such, but the data is off, since you're not using it. That saves a lot of battery for me. You can also set it on a timed profile, where it shuts off all network connectivity during a set time.

Thanks I'll give that app a try.
Also I just feel I'm being mis-leaded by others then. Because I read on the android Forums people play games from 1-2 hours, stop, go to the store or mall for like 5 hours, come home, play again for another hour, and sleep and wake up with it at 7% charge or something.
Are you saying ti's normal for my battery to suck that much juice on Dead Space?
Dead Space is one of the most graphics intensive games you'll get to see in this phone. It's not Cut the Rope...
Well.. despite my other questions is anyone able to answer them..? ABout the battery stats app and such?
Also what would seem to be a normal rate of 1% battery loss? How many mins or hours do you think seems normal?

Did you wipe your battery stats before installing the rom? Let it drain to 0%, charge it without interruption? after that then you must let it drain fully and recharge too 100% without interruption again. This will "train" the battery. I have a battery calibration app if you'd like to use it
I would suggest you to do a fresh install. Wipe everything and start afresh. Don't restore anything and see what happens.

Yes I have done this. But ONCE. I haven't let it die again yet. Using Battery Defender is saving it's battery atm. Should I kill it again and let it do so?
Also for the Battery Calibration don't I have to do some weird thing with getting the phone to power on without the battery?

Make a backup of all your data, then do a fresh install. The battery calibration app is simple, charge your phone to 100% and click calibrate. Then let it die to 0% and fully charge without any disruption..it's pretty simple

The battery calibration has nothing to do with a full wipe and reinstall. The fresh install is simply to fix problems that you are having, that no one else has, or doesn't have in such great force.
If you're worried about losing your data, get an app called Titanium Backup. It will allow you to backup your apps and app data to your sd card, then restore them at any time you deem necessary. There is a free version, but I would definitely recommend buying the unlock key. It makes your restores faster, and enables some specific functions that are locked out of the free version. This is my third Android phone, and the app has proven its usefulness time and time again, across each of them. It's the best way to port installed apps from phone to phone, as well.

Here's the thing. I have Titanium Backup. XD And also, I have done a Fresh Install before because I had this ROM then I switched to ICS Beta which was terrible so I fresh installed the UK Rom again and it didn't make a difference to when I had it before ICS BETA, so does that count? x.x

Is your battery life any different now than it was before the ICS beta?

Well...it seemed my battery life was better on the STOCK Verizon ROM but that ROM sucks for everything else..
So does anyone have the link to that battery calibrator app?
I am trying to troubleshoot my battery drain issue so I have been inserting a fully charged battery into my Note 2 just before bed.
Stock 4.1.2 ROM
Rooted
Night 1
Before bed: 100% battery, airplane mode
Wake up 7.5 hours later: 100% battery life
Night 2
Before bed: 100% battery, WiFi connected, background sync enabled
Wake up 7.6 hours later: 54% battery life
I have Greenify and BetterBatteryStats and still can't figure out what is sucking down the power.
Sync Interval:
Twitter: 4 hour
Facebook: 30 min
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Any help would be appreciated!
I think you really have nearly answered your own question - it's the syncing that's killing your battery. FB is notoriously bad at draining a battery all on its own and the others may be bad too. The dead giveaway is the phone isn't deep sleeping anymore with sync on. Keep up your experiments but freeze each app/process in turn to see how bad each one is and you'll find out. No need to leave it over night - an hour or two should be plenty to find out. In fact, if you have your phone set for max battery life, it should go into deep sleep within minutes of locking it. Personally I only sync manually and that's including email - but I'm not too plugged in so I don't mind checking a couple times a day manually. It does mean killer battery life though! Really any process that is constantly waking up your phone will do the same thing as fb - Google Now with location history on is another bad one.

I use fb and I get no battery drain from it
Still unsure about which app is the main culprit. Facebook seems like it could be the biggest problem. Attached is my dump from BBS (BetterBatteryStats) I tried the same thing as the night before except I did the following
Facebook Sync: Never
Twitter Sync: Never
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Night 3:
100% battery before bed, background sync enabled.
52% Battery by wake up.
NOTE: 10076 (Wifi) (com.android.vending.Google Play Store): 86.0 MBytes 95.3% was my apps updating just after boot.After all apps were done updating, I put the phone to sleep until morning.
Things I am going trying.
Freeze Samsung Push
Freeze ChatOn
Greenify Facebook
You need to understand that virtually any app that has the ability to poll your phone and push updates to it automatically without you visibly seeing it is going to drain your battery. This includes:
1. GPS
2. Having your data on in general (networks push packets to each other to stay within protocols regardless)
3. Google Accounts (syncs your calender, contacts, people, etc.)
4. Google Now
5. Mail
etc, etc.
I know this is a little off subject but will face book still drain Battery even if you have location off and sync off?
Facebook Messenger was an issue. It kept waking up my device. I have been doing some testing though and have had almost no luck until tonight.
I disabled WiFi before bed with 100% battery. 7 hours later, 91% battery.
I need to find which apps are using WiFi so heavily.
Go grab greenify from play store

I have been using Greenify the whole time. Currently, it looks like when on WiFi apps are going crazy with connecting and waking up the phone. On Mobile, I got much better battery life.
Try backing up all ur data on internal and SD card.. Then do a complete fresh install.

Yes. I have the same experience. When WiFi is on, the battery life is much worse.

Ok Wi-Fi being on won't kill your battery. Maybe you need to set your to, keep Wi-Fi on during sleep= NEVER. That'll help your battey life some what..

My battery seems to be draining quite fast. I have removed a lot of bloatware, but I'm not getting the type of performance that others are getting.
It has lost 70% in 5 hours just doing a little browsing, watching a 20minute video and playing a game for half an hour. This was with Wifi on, and mobile data switched off, and background data switched off too.
I've had the device for a week now and I've charged it every day.
Any Ideas on how to improve it?

Could well be your brightness level? Are you using autobrightness or is it on a fixed level (I hope its not fixed at 100%!)
If you use autobrightness try using an app like LUX auto brightness instead.

Thanks for that, I did have it on Auto brightness for the first few days, but the last few days I switched it off just in case it was that, but the problem remained. I will try LUX auto as you suggested.

I am rooted, and thanks for the suggestion of that app - I will get it right now and test with it today, I'll let you know later how I get on.
My guess is a corrupted media file somewhere which is causing your media server to prevent the phone from going into deep sleep. When you go to settings , battery, is media the no 1 juice sucker?

Yeah I got rid of the radio and media player from one of the homescreens as they showed quite heavily in wake up time. but the battery still kept draining fast.
Just buy another battery and enjoy the pleasures of experiencing a QHD beast I have 3 batteries (2 standard) and managed to strike a freebie on the 3rd battery ..

I wouldn't mind, but I just bought it 8 days ago, people are experiencing a lot longer battery life than I can.
Immediately just played a game and look how much has gone.
Why is Android system using up so much? I've even got location switched off and Google search etc. is deleted.
If 're not using Xposed Frameowrk for tweaks, looking into enabling ART - I did that and my battery life has been impressive.

I did try that, but it didn't work and the phone was a bit laggy. Why would android system take up 15% of whatever the battery uses? I'm getting so frustrated, I might do a factory reset.
Here is the picture of what is being used, down 40% in such a short time. :

Aosed to make things smoother not laggy
Sounds like you have something eating up massive resources.

Must be, but I don't have any idea what it is:
Here is a screenshot a few minutes after the last screenshot - another 10% down, and I watched a 8 minute video:

How long has that screen been on for?
A shot in the dark:
Do you skype? Skype was draining the battery down in the Nexus 7 2013 even when you were not using it. I disabled it and the battery improved greatly.
Another option:
It sounds to me that there's an app that is draining the battery down a whole lot. I would try to isolate that app (by deleting each one you downloaded one at a time) until you have found it.

I don't have skype, but I like your idea - I've gotten rid of almost all the bloatware stuff. What I think I'll do now is charge it to max. DO a factory reset and not allow Google to start downloading all my apps again.
Funny thing though - when I charged it last night and unplugged it for 3 hours it only dropped a couple of percent. It started dying rapidly after I opened up a few other apps.
What I'll do now is charge do a factory reset, then switch it off, then charge to max before turning it on again. When I first got it, it turned on as soon as I plugged it in. did the same happen for everyone?
What you might want to do is download Greenify on the play store. This will tell you what apps are running in the background and then it will turn them off (hibernate).

Make sure that you leave the battery charging for about 10-15 minutes more after your cradle light turns green. Sometimes the battery isn't fully charged despite the cradle light turning green. 30 minutes on a game shouldn't be using that much battery consumption.
I usually get about 10-12 hours or more on each of my batteries ( video calling, chatting, games and my 4g is turned on 90% of the time
Try this from Google Play

You can read their reviews and install the app but don't download too many battery monitor apps Keep us posted after a few days of monitoring Good luck :good:
