Yet another extended battery 2400mah

Anybody using one of these 2400mah batteries on their evo?

not bad for the price

I just don't see why people get extended batteries when kernels now days are supporting my battery all day dragging on into the mornings.. i guess every phone reacts differently.

I've tried all the hottest kernels and battery saving tricks and still average only 8hrs under real world use
Running Evo Deck 1.2.1, display at 12%, couple widgets, data off (using wifi at home) , sync off, and all of that. Underclocked, undervolted too.
Browsing, xda app, etc results in 20% battery usage per hour. Battery consumption is zero at idle, but drops like a rock if i use the phone at all.

I'm using Seidio 3500mah and enjoying the 5 days no charging. I use my phone mainly for texting/facebooking.

I get 20+ hours of heavy use, xda, music, browsing I'm sixteen so my girlfriend is ALWAYS texting me some pandora, youtube tossed in there
Oh and I'm using a live wallpaper (pixel rain) I keep sync on, gmail hourly everything else daily, weather on the half hour, right now my phone is at 17 hours with 38 percent left.
Under lighter usage ( more pocket time, less texting, less sitting around bored on xda and Facebook )
30 hours is pretty common

Zac95....I hate you lol.
Maybe my batteries are shot - their health shows "good " though. I have two OEM 1500 batteries that I swap, but I did buy an HTC 2150mAh, just waiting on my battery cover to arrive before I use it.

Battery calibration is very important, don't know how I lived without it
Setting the VM heap to 48 allows the dalvik garbage collector to run less, improving battery
Chainfire 3d helps with anything graphical, makes home using lwps smoother, games run better etc, also saves battery by making all animations, graphics processing more efficient
If you use apps2sd bumping the cache makes it faster, and more efficient saving battery
Also updating to the latest radios etc, and making sure your prls and profile is up to date is essential, many aosp users, formerly including my self forget about that stuff
I've spent a huge amount of time expirementing with different setups, I think I've found my phones sweet spot
I have loads of friends with rooted evos, mine has the best battery and is typically fastest (chainfire 3d) makes everything snappier
Maybe with all of this info you can test these apps / settings and find your phones sweet spot. Good luck man

I wonder how the mfg pulled that off? My HTC 2150mAh battery is twice as thick as the 1500. I'd bet that that eBay battery will not yield the stated 2100mAh.

I'll agree with Zac here,
evo 3d with CM7 nightly, SavagedZen 2.2.1 CFS. removed all the crap i dont use or think they suck the battery down. live wallpaper etc.
InteractiveX governor, 245-1113mhz
No setCPU.
no juice defender
no taskkiller.
no 4g - no gps - no wifi
blutooth ON
3g always ON.
battery calibrated is a must
display set to manual around 33% brightness. but i change it on the fly (swipe the notif bar).
Now the results are pretty interesting here:
With the stock battery and all the above; if the reception is good, i can go for 2 days with moderate usage. yes i know i night i sleep, so it idles nicely.
If the signal is not so good, it will destroy the battery, and can't really get anything more than 13hours.
My typical use:
unplug at 10am.
use the phone normally.
plug it back in at midnight that night, and i would have between 35% or up to 67% battery left in the phone, depending on the factors mentioned.
Which to me, going all day is all i wanted before i started tweaking. Mission accomplished.
The quality of the reception is a killer, i'll tell you.

I bought a 3500mah battery from the same company, and it is trash.

are there any extended batteries that fit in an otterbox commuter case?

[TIP]Increase battery life by at least 50%

Here is a tip on how to increase battery life by at least 50%. For me, it has increased by 83%, given that my S II is relatively new (3 months old). It is an app in the market which you can get for free: JuiceDefender
MUST:
Remove any task killing apps (Advanced Task Killer) otherwise this app is useless as it needs to be on at all times.
I have my settings set to Aggressive, as I don't use my phone much during the day.
My normal on the Bombaridier v3.5 ROM by TricH was 100% at 7:00 AM and 88% at 10:23 AM with only 40 minutes of music and standby with no data connection or Wi-Fi. With JuiceDefender, I get 100% at 7:00 AM and 98% at 10:23 AM with the same circumstances of use. It is worth downloading and will extend battery life. I have 83% more battery life according to my math (which is (10/12)=(x/100)) and it is amazing.

I agree that JuiceDefender is an excellent product for extending battery life.
I have the "Ultimate" version.
JuiceDefender alongside "Battery Monitor Widget Pro" is the killer combination...
I did notice one slight bug with JuiceDefender (JD) - there's a known issue with wifi management. Phone turns itself off occasionally. The fix is to simply set JD "disabled" for WiFi management - problem then goes away.
I also listen to music (Pandora) over a Bluetooth headset (about 3 hours per day).
I regularly get about 18hrs+ (combination, on average: 3 hours on voice, lots of email). Stock, rooted ROM... bloat removed.

I agree Juice defender is purely amazing, according to JD stats, I get 1.83% more battery life, that's with aggressive settings.
Ps: Thanks for the Wifi tip

It'll be hard pressed for any app to extend my 3+ days of usage on a single charge. Just sayin..

I just bought the ultimate. I will let everyone know how it goes after a week of using it.

The first thing that came to mind is; haters gotta hate.
I use it just fine with my purposes.
Check/write emails, make calls. Nifty info widgets for updates. I just don't use it for everything because that's just silly. That's the reason why I get such a long run-time. I already have a dedicated media device, no need to watch videos, etc etc on the phone.
Just because most people don't get more than a day usage, don't mean it doesn't happen.

whoa 18+ with 3hours voice is killer.
i barely get about 16 with 2.5 voice and roughly 2.5 display on time
just fyi to those who don't know. voice weighs heaviest on battery usage, even more so than display.

I can get 2 days with moderate use but I dont realy tLk on the phone and I use wifi most of the time

Seems to me that most people who use this app set to Aggressive, get around 83% more battery life. Amazing app and my math was on point.

on a side note, has anyone tried to undervolt and underclock? if so, which is the best program for this? i am using setcpu but doesn't seem to allow voltage tweaks. with JD and undervolting, i can only imagine what type of battery life this would have

Use the Darkside X kernel and under clock to 1128000 or something and it still runs smooth.

Best thing you can do to to increase battery life is to disable all those Google services. I don't know why but I make it pretty clear in the settings that I do not want any auto-update or syncing of any sort but it happens anyway, so I have to manually freeze all the **** that Google insists on running 24/7.

Thanks for the tip! Extra battery life is always welcome.

Although jd isn't exactly new, but there seems to be a lot of people who just heard of it now. Not bashing but this just shows that there seems to be a lot of new android users or well xda members since the release of our awesome device. I bet most are all former ifags (don't take me seriously).

Lmao. I think this made my day. xD I was using juice defender way back when the droid eris was new and I still do! It works wonders. When I had a dell streak I went from 6-8 hrs of batt life with no usage to over 2 days.

Sorry if I sound like a tool for asking this but if you turn off the Google gmail and calender sync then how do you get your emails?
U have to manually check for mail all the time?
sorry, having issues with my battery also. I use Juice Defender but the free version - everyone that is having success with it are you using the purchase one, Juice Defender Ultimate?

Ive had my phone since october, and the battery has gotten better and better. And im not doing anything special, stock rom, no juice defender, no task killer, nothing of that sort.
I use wifi tether almost all day at work(about 6 to 8 hours) and I still have 20 to 30 percent left when i head home.

EXTREME Battery Loss (CM9)

Greetings!
I am currently using a Sprint Epic 4g (SPH-D700) with ICS (CM9-epicmtd) and the regular Cyanogenmod kernel. I have followed the guides on here and on the CM9 forums for battery life including blacklisting certain apps, changing settings, messing around with performance settings, etc. With all of that, I usually get around a 4 hour battery with normal use (Spotify Music, GVoice Messaging, Occasional Reddit App), during school I have to charge it every other class or else it will die. I have become used to carrying my charger around but I think I figured something out so I wanted to know your ideas on it.
At home, I only use Wifi, I turn off 3g access. I can get 8hour battery at home. But right as I turn on 3g, I get MAJOR battery drain and the phone gets extremely hot.
I just wanted to know, is it the phone? The battery? The OS?
Thanks

USe this app (http://forum.xda-developers.com/showthread.php?t=1179809)
It will show you what processes/apps are eating battery. I'd also suggest you do a dry run with turning off all sync/streams/data usage for a day or so to see how the battery reacts. Chances are good that you also have an old battery.

pull your battery out and pinch it if it feels any way shape or sort spongy , go to sprint and get a new one they wont ask any questions if you have insurance and your in and out in 5 min

Didn't wanna make a whole new thread so I hope this would be the right place to post this since I also want to know "is it the phone, the battery, or the os?" lol.
I'm having terriblee battery results with my phone. Its been happening for like 3 weeks now and I thought the reason was because my batteries got wet (I have like 5 batteries, 4-1500 mAh, and 1-1800mAh). They all die pretty quick I can get about 2-2 1/2 hours of screen time in about 12-14 hours. Which is terrible cuz I have screenshots that I randomlly took of my battery from before and there's times where I would get 4hrs of screen time on in about 20 hours total or I could go about 30 hours with 3 hours of on screen time. I've tried different ROMs and even odined to stock and tested things out and still my phone dies super quick.
My questions:
When the battery has water damage the little paper tab thingy turns pink right? What if it is removed completely?
And is there anyway that my phone just isn't working right because of having damaged battery?
Because right now I'm using a 3500 mAh battery and I'm getting almost the same results that I used to get with my 1500 mAh ones.
Does anyone know anything I could try to see what happens lol?

Never understood some people's philosophy on extending battery life.

I've read a lot of posts complaining about battery life, and other posts about users suggesting ways to improve battery life. I've read stuff like, disable LED, haptic feedback, lower volume, lower brightness, LTE turned off, underclocking, turning off sync, live wallpapers, etc, etc. To me a lot of people are crippling their phones. If your battery can last you 10 hours, that's enough because you'll probably be somewhere you can plug in. What's the point of being able to go for 20 hours when you'll probably have the opportunity to charge it before then? It's better to have and enjoy all the features.
Maybe somebody can chime in and give me their point of view.

I agree. I would never want to sacrifice a feature just to extend the phone's battery life. Instead I use a custom rom that has all the features (and more) and 12 to 18 hours of battery life.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Part of the issue is a sociological thinking pattern between wanting "more" and needing it. Depending upon the type of lifestyle you live, sometimes, battery life is of dire importance to have if you're constantly migrating around. But I agree, some people who aren't in that sort of disposition go overboard with it.

I just bought a bigger battery :good:

I agree wholeheartedly. If your battery is lasting you through your day (which mine does, and more) then why try to conserve it?

Yea its funny stuff people complain their battery only lasts 20 hrs but yet they want it to be able to do everything a computer can do and more....
Sent from my SGH-I747M using xda premium

The only conscious effort i made to extend my battery life was to undervolt the CPU a bit, but this was more for the lower temperature advantages with extra battery life being an added bonus. Beyond that i turned off things i dont use like BT, no need having something running that i have no use for. Overall i was happy with the stock battery except for any kind of heavy video or game usage which drains it pretty quick - solution : bigger F'n battery :highfive:

i agree that some people seem a bit obsessive about it. but we shouldn give bad battery life a pass either. hopefully we will see some sort of advancement in batteries to have better battery life while keeping them at a decent size.
i was kinda worried id have horrible battery life with the S3 being that its LTE. my last LTE phone was so bad it would die after 8 hours idle.

I keep the brightness to the lowest setting anyway, but I do all of this because I go to school fairly far from my home, and I'd like to be able to play games on my phone without wasting 5% battery every 15 minutes. I haven't switched power saving off since I bought the phone.
Stock ICS on my S3

I bought the extended battery because I like playing games from time to time and I don't want tl have to worry about my phone dropping 15% after playing something for 5 minutes. Like someone else said earlier. It really depends on the kind of lifestyle you live. I for one don't mind having the extended battery on my phone but I do miss how light it used to be.

How heavy is it? Does it fit in a case?

For me, and I want as much battery life as possible to avoid those situations where there is no way to charge you phone even if that only happens 1 a month or less.. As a parent I can't just let my phone die on me... I always need enough to be able to take or make that important calls/text. My goal is to have at least 20-30 hours of battery life per charge.
I think the only major feature I've given up is live wall paper. Other then that, it is just disabling other unused apps like gtalk, talkback, Google bookmarked sync. As well I've uv my phone as much as I can and run a 1350 max clock speed. I really don't see any major dip in performance as long as you do it right . I do use Tasker to disable syncing globally when the screen is off and make sure it automatically disable bluetooth after 10 mins once it disconnect. Also I have the Y5 app to automatically toggle wifi based off my network location. The most useful battery saver I've found is to set my wifi to only connect when the screen is on. Seems kind of backwards but it works well when very little data is process during idle rather the the phone requiring to keep a constant connection to wifi.

I'm also one of those people that closes an app as soon as I'm done with it. Use an app, press the home button, release and hold home, swipe the app away, sigh in relief. An old habit carried from my S2 Skyrocket, where getting 8 hours on stock was above average.

I have my screen brightness at 40-50 auto off.. i cant imagine turning it all the way down like alot of people say.. even when auto brightness is on it look very dull and dark at night to me.. Same thing for my tv with auto brightness.. but i still get good battery life. I am fully charged at about 6pm i use it till bedtime and use it for my alarm.. get up 4 am and when i get home at 2pm its still over 40%.. only thing i do is close all my running apps by holding home button a few times a day and same with ram

I work in an office so it's plugged in for the 2 hours before I leave so I have everything on full most of the day (brightness, lte...). Also, by undervolting I'm getting 30% more battery.
I think tips on increasing battery life like turning off lte and brightness are for people who can't plug in throughout the day or for emergency situations when you want to get the most out of your phone because there's some reason you can't charge.
Sent from my SGH-I747 using xda app-developers app

I get anywhere from 12 - 23 hours depending on whether I'm at work or off. I can live with that...but there are situations where being unreachable poses a problem.
So, to deal with my phone addiction, I got an original replacement battery. Always have it charged and on me. When the phone shuts down, pop in the replacement and your done. About a minute without a phone. This way I don't have to UV, worry about brightness, WiFi, Bluetooth, etc...
I can't deal with the bulk of an extended battery.

30% more battery by simply undervolting? I think that's quite an overstretched statement. How is that even possible?

Its not possible. Not by solely UVing. The sole purpose of undervolting is so that your phone dosent overheat when running high clock speeds. Saving battery is just a perk. You might save a few percent with the undervolt but nowhere around 30%. But don't take my word for it.....

Mine's absolutely horrid, I can't for the life of me figure out what the hell's wrong with it. I'll run out of battery after about 12 hours, with the screen time at 1 hour and maybe 30 minutes if I'm lucky? The phone drinks away my battery in standby mode like a former alcoholic united with an opened beer. When I was on ICS, turning off 4G every time the screen was off with the AutomateIt app would give me excellent battery life. Ever since Jelly Bean, it doesn't seem to make a difference. I just don't even bother using AutomateIt anymore, I even uninstalled it. Useless. I check marked the option, "Restrict Background Data," but I actually had worse results with that on even. Following the thread about the Guide to good battery life, I turned off auto-sync. The only thing that seems to do for me is not get my emails in real time. No effect on the battery though. I'm guessing the battery drain has something to do with being on data (even though turning it off doesn't seem to do much) because everytime I go to school where there's little WiFi, battery's worse. Also, somehow my Messaging app takes up more battery than the screen. What's with that? I'll text every now and then, but it shouldn't eat away my battery like a fat man with the last batch of Twinkies. Enough with the dumb similes, haha, but I actually need help with this. I really don't wanna buy a battery off eBay cause the damn people are too lazy to send you the battery until a month passes, and I hate charging in the middle of the day.
I'm on 100% stock. I used to root and mess around with a ton of ROMs, but then I realized all my favourite ROMs were the ones closest to stock...

.... look at the eBay expected arrival and/or look for a seller in the USA ?
Anyway, that bit aside - have you installed something like BetterBatteryStats to be able to see what the problem is so you can fix it ?

It's exactly like mine. However, some users actually got theirs up to 5 hours screen time. How? I'll never know

5 hours... how !?
Easy !
I'm on stock and if I'm almost all the day on WIFI, not playing too much games, and with auto-brightness,
I can get 5 to 6 hours screen time.
(but on 4G all the day, it's more around 3 hours screen time)

This is what most people get with normal use around 14 to 16 hours and 4 to 5 hours screen time. I think the biggest issue is that 4G radio that most people have on all the time. I I have wifi everywhere so most of the time I have mine off that helps a ton. Plus all the sync stuff off, I get about 6 hours over 17 hours battery life and about 30 to 40% brightness.

14-16 is what was normal for me when I first got my GS3 (after JB update). If you want more battery life, I recommend trying juice defender (custom settings for data off while locked). If you have stretches where you don't use your phone it works really well. Just thought I would throw that out there.
