Hi,
I was wondernig if any of you guys have used this app on your stock, non-rooted phones?
https://play.google.com/store/apps/...xLDMsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
I feel like I should be getting better battery life.
One more question, if i get a replacement battery, is there a need to do anything to wipe out battery stats, or just pop in the battery and go??
Thanks again

Unfortunately not. This is what it says in the description:
Requirements: Android 2.1+ | Root permissions
Apparently it doesn't even start if you were to have downloaded it. It needs to access files only accessible for those with Root access.
As to swapping the battery, I assume it should be fine, but I haven't changed batteries myself...

Yes works great, but only works on rooted phones.

Can anybody show the proper way to use juice defender while using the seidio 3500mah battery

I don't think you need juice defender with that battery but are you using a custom kernel or rom?

Buy UltimateJuice! to improve it accordingly the Pro version of JuiceDefender shows improvement for me, I get x1.90 the battery life I get and needed with this.
I currently use a 3500mah battery with UltimateJuice! installed.
Helps me quite a bit, but with the big battery I have is given me x1.47 increase in battery life rather than my old battery that came with Sprint HTC EVO, That was increased and perkier if you get my drift saying that x1.90 was at its peak for battery live. I've recorded my hours kinda from my head remembering it, don't have any pictures, but I can tell you that with the normal battery, I get roughly 15 hours hardtime battery life using UltimateJuice! before also, on the new battery 3500mah, I have my phone uncharged for 1 hr and it's at 93% battery life lol, but it's the same build up in competition wise, I would say go for UltimateJuice! if you can.
Ok can you show me how to apply and how to save send me a picture of how your using it

Sure, just download it / buy it from the market (Pro Version) and click on the program in your phone, give it root permissions (yes), Click on "Enable" and the program itself should help your battery life in that way.

He's not rooted so he can't give it root permission. With the 3500 I don't even think he needs juicedefender just use the stock #17 kernel it's pretty decent with battery life I and screen off is great so i think stock #17 the 3500 bat is a great combo but if you really want to get better slightly better battery root your phone, get setcpu, download net cfs kernel probably one with smartass and set setcpu to smartass and your battery should last you more than a day maybe two depending on how you use it. but i'm a heavy heave user i get about 12-15 hours of use with the stock evo battery,

Does the rooted stock have a better battery life than regular stock.

Hi..... I just wanted to know if the rooted stock Rom has better battery life than the regular unrooted stock because the regular stock kills the battery really fast.

Rooting by itself doesn't do anything so...
No
i thought stock battery life was good. Maybe it is something running in the background that is killing your batter.
Being rooted you can remove a lot of bloatware to save battery life.

All superuser (root) is is a program designed to grant applications admin access to the device, rooting itself inpacts performance/stability in NO way whatsoever..
if you want better battery life, i recommend flashing a custom rom

which gives you access to remove bloatware... did you miss that part? If you strip down your phone and freeze/uninstall apps that ran in the background and/or used data when you don't want it to, then you will improve your battery life.
I think you fail to see what the OP was asking. it was about battery life, not performance or stability.
if you check the running applications and freeze the ones that run all day then ya better battery but obviously just rooting isnt gonna do it

Im with doug on this one, i think youre taking this too far. The op inquired if a STOCK rooted rom had beyyer battery life as opposed to a unrooted STOCK rom. As doug said, a rooted completely stock rom offers no battery life imprpvements on its own. Now performance to me is defined as the optimal battery life and efficiency of the device.

Darksides and Juggernaut are the pretty much stock with bloatware removed and some additional goodies which are super helpful such as the notification bar toggles. I'm currently using darksides and I'm seeing very good battery life on moderate use (2 hours display time at 50% brightness, 1 hour on Spotify streaming music and I'm down to 30% battery. Total uptime since last charge 13 hours 51 minutes.) Perhaps not the best battery life out there but it does the job for me. Also if you're gonna install either ROM, undervolt the cpu as well as underclocking it. It really doesn't affect the performance, its hardly noticeable actually.

Ah i see what you guys are getting at. Just misinterpretation of both parties. Yes rooting itself does nothing, but obviously something is killing the op's battery. I was trying to inform the benefits of having root and how it may improve his battery life by removing whatever is killing his phone.. However if it's from an app he uses then no help there.

If you want better battery life you can always try change the kernel first. You don't need to do pesky full wipes so you retain pretty much all your settings and stuff.
To start off, I think Faux's is pretty awesome.
You're not going to gain leaps and bounds in battery life until you find what is eating all that power on your phone. It is typically an app you installed, as I don't find the t-mobile pre-installed ones to be that horrible, except for lookout security. I think that'll be a big potential battery hog. OR it can simply be your screen brightness. The trick I find is to set it on the lowest setting and just be SOL when you're outside I mean heck, I really want that battery life!
You can always practice better battery saving techniques, like not leaving the wifi or wireless data on when not in use.

Battery draining at 1% every 2minutes, help!

Ok guys, so i got my replacement siedio 3800, and after charging it initially for 12hrs, after I got it. The battery issue is still here. When the phone is not on, or standby, it is fine, however while using it, the % ofbattery life just keeps dropping, 1% every 2minutes about I timed it and averaged it. I checked GSAM 29.5% is used by apps, i have only 3g enabled, no wifi, bt, or gps. Plz help me get this fixed, same problem was with the Razr maxx. I am using Bamf JB rom. About to throw the stupid phone lol!
And i do have full 3g/4g, but only 3g enabled, with good signal strength
if you're saying it happens on your maxx as well... you have a app burning your battery
Find the app
Delete non essential apps
-----------
god is the creation of people with nowhere left to turn
how do i find it? i am stock bamf jb , with gapps, thats all, and under battery, no apps are burning a lot, web browser was 6% was the most. and GSAM said only 29.5% of battery was apps
could it be google talk, or aim? i usually exit out of both when done. But google services is always on in running apps, but didnt want to disable, wasnt sure if that was for gmail. auto sync is off

What do you mean stock BAMF? BAMF is custom ROM and rooted... If you ARE rooted, easy. Download betterbatterystat from Play Store and see which app drains the battery the most.
is gsam the same type of app? It says apps are using 29.5% and browser is highest at 8%. I really dont want to pay $3 for the betterbatterystats

then go back to stock. if the problems happens on stock WITH NO APPS, then you have a bad battery.
if it doesnt happen, you have a crappy app somewhere.

Hello. That is why people invented .apk files. Just download a .apk file. It is what everyone does.
Galaxy Nexus-codenameandroid rom
usually bad/rogue apps wont show up on those battery apps. I remember i restored app settings/etc for dolphin from 2.3 to ics and that was the cause. Removing data/cache and the app itself removed the battery drain.
Do a binary search of apps (install half of them, if it drains then the culprit is in that half, if not in the other half, etc etc).
Try to disable as much syncing as you can, and definitely disable instant upload.
Betterbatterystats apk from the thread that deeren linked to. cpuspy might also help.
imo you should perform a reset and start over.....its faster

I didn't.
Use WiFi when you can it what helps me. I am now on Affinity ROM and got 21.5 hours with 2 hours 45 minutes screen time. With the 2100 mAh battery. I am using the Glados kernel it came with and no tweaks to it.

Trying to track down a rogue application is hard work, do it only if you feel like you're up for it.
Apps with good reviews and comments don't usually cause such a problem but checking per app reviews/ratings will take you, I don't know, maybe till you grow old.
Best thing to do is to reset everything and start light, with only a few apps, then install another batch of apps if there is no problem with installation of previous batch, this way you can find the culprit.
Good luck.
OK well I am back to 100% stock like suggested and charged my battery 10-100% overnight. Still losing lots of battery. 13minutes cut me to 94%. So it was the rom after 3hrs of getting back to stock. This is also my second siedio 3800 battery. What's next?

[Q]Battery Draining 20% in 15minutes

Hey everyone, I've tried posting this in the battery life thread but I've gotten no help in resolving this issue. This morning I unplugged the phone from the charger(I leave it plugged in overnight) and the phone dropped 20 perecent of the battery in under 15 minutes. At this point the only thing i was doing with the phone was checking a text message I had recieved.
I have optimized my phone so that I it only updates email and many other services manually but regardless a 20 percent drop in 15 minutes is not acceptable. I have calibrated my battery using the battery calibration app which hasn't worked. I have rooted my phone and am currently using the stock bell rom. Additionally, I am also using nova launcher on my phone and that is about it. The only strange thing that I've done to my phone is use a blackberry charger to charge my battery but I don't think this is the issue.
At this point I am beyond frustrated with this device need a solution now or I'll have to take it in to get fixed. Does granting root access void my warrenty? Do I need to unroot before I go to bell. I will post images of my phone stats in the next post.
thank you in advance for your help.

Before you send it in or take it somewhere, download" Better Battery Stats" and see if you can target where the drain is coming from. And yes, you will need to return to stock but before you do you will need to run the triangle away app. That will reduce your flash counter to 0. I'm betting you will be able to find out the problem with Better Battery Stats though. Check your PM's. I sent you something helpful that I didn't wanna post on here.

I don't know what Kernel I'm using but I am using the stock Jellybean rom. I've basically just given myself root access and installed the latest stock firmware. I am using my original charger(plugged into the wall) and last night i left my phone plugged in for over 8 hours so its definitely getting a full charge.
When I was am girlfriends house I used her dads blackberry charger to charge my phone but I don't think that would have wrecked the battery in such a way. I have noticed that the battery seems to draing very rapidly up until about 75% at which point battery consumption returns to normal. I can try charging my phone whilst plugged into my pc if you think that maybe make a difference.

Ok. I gotcha. The charger thing only matters if you use the wrong charger all the time. It doesn't charge it properly. It doesn't do any permanent damage that I know of. I would advise using the Samsung charger whenever possible. Anyways, let your battery drain all the way down to 0 til the phone shuts itself off then charge it all the way back to %100 without taking it off the charger. This should recalibrate your battery. It just got knocked outta wack. It happens sometimes. Let me know if this works. And by the way, you're probably running the stock kernel. You can always get that info by going to settings/about device. Let me know if this helped.

I have a friend who had the same problem, he had to get his phone turned in because his motherboard was malfunctioning.
He ended up getting a full phone replacement and hasn't had the problem since.
If you continue to have this issue I'd definitely get it looked at by your providers retail location.
edit: If you root you will want to avoid tripping the flash counter, which from what I've seen lately is very difficult.
Telus flat out told me in the store that they don't even care if it's rommed and have asked me what I like to use for roms etc which is nice, I don't know if Bell is as lenient.
Best of luck.

The previously mentioned %68 after 5 hours is pretty typical of what I get running stock kernel with ParanoidKANGdroid 1.40. That's while I'm at work, so I'm usually connected to WiFi, on silent, with most of my usage during that time being texting, but I do usually play games on my lunch. I have thought that was a bit excessive drain, so yesterday I set up CPU Editor and set my maximum CPU frequency to 702 MHz. I got pretty close to the same drain.
Today so far, I have the stats uploaded, and that seems much better to me so far.

Thanks for posting this thread, I'm having the exact same problem. It's been an interesting go for me.
Some times it does it and other times it doesn't.
I'm using cyanogenmod nightly from 1.3.13 with the latest ktoonez kernel and I've noticed that today, it's sucking battery more than ever. I'll attach a screenshot, but I think there might be something with the charger as mentioned earlier in the thread. When I charge it at night, I'm charging it off an old blackberry micro usb cable with a generic AC to usb plug.
I'm going to let this thing drain out and die and charge it back up to 100% and see if that works for me.
Does kernel make a big difference for battery life? For that matter, what are the main advantages of different kernels?

It definitely helped me. The main advantages that I see with running the kernel that I use is the ability to undervolt & overclock it. This will allow you to run the same frequency that you normally would but at a lower voltage therefore reducing heat & battery consumption. Google it & do some reading & educate yourself on it before you make your decision. I am glad that I decided to do it.

AOKP allows you to change those settings doesn't it? Or only with a custom kernel?

Yes I think AOKP will allow you to change some settings around. It will allow you to set you min/max clock speed & your gov & scheduler. A custom kernel will give you different gov, schedulers, & different min/max speeds. I use Ktoonsez's kernel & it comes packaged with an app called Ktweaker. He advises to use this app to control your kernel settings. I don't think that they will apply properly if you don't. Also you can undervolt with Ktweaker.

I'm on a i747 galaxy s3 and I've just downloaded the Pacman rom.I've downloaded other roms so i know i flashed this one correctly. I even re flashed it again last night. Both yesterday and tonight my battery went to 100%-%50 in one hour. After i charged it up it would decline 20 percent in one hour. I look at the time screen time on and to see if anything is waking up my phone excessively. And all sings say to no. Any tips? I feel like I'm back in pre ics days haha.

when you flash a new ROM it is recommended to wipe Cache, Dalvik, Factory Reset and System. If you've done that you should be okay with the installation portion.
Have you modified the kernel at all, have you over clocked anything?
Go to the play store and download BetterBatteryStats. This will help you determine the cause.

Have you modified the kernel at all, have you over clocked anything?
Go to the play store and download BetterBatteryStats. This will help you determine the cause.

Yeah i have. When i installed i did the whole wipe thing. And I'm useing gsm batter monitor. All the readings are normal which is the weird part to me. And no i haven't over clocked (No need to imo) and haven't modified the kernel. I know that on previous androids you would have to do a wipe batter stats. I actually tried looking for that in CMW but i wasn't able to find it. Would you have to wipe the battery stats using "batter calibration" or wiping it manually in CMW? Or is that even necessary for galaxy s3s?

I would also recommend using Better Battery Stats as it is the best one I think. I always use the battery calibration app after I flash a new ROM. It usually takes a couple days or so anyways to have the new ROM settle in and everything. After a couple days you should see your battery life where it should be and not draining so fast depending on what your settings are.
Battery calibration is a myth and has been confirmed by Google themselves. Its all over the forum and wholly unnecessary. Those apps are useless. The only way to truly let your battery stats "calibrate" is to let the ROM and kernel settle into the phone after a few charge cycles.
Here's the Google+ discussion by one of Google's people: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
If you want to keep "calibrating" your battery for the warm and fuzzies, its your time and device.

Wow thats interesting. Everywhere i go people say that battery calibration is a necessary part when switching roms. Just out of curiosity what do you do for better battery life ? Basically what you use and not use settings wise.

Everyone's battery life varies. Honestly, it doesn't matter the ROM. The kernel does play a part in it but its how YOU use the phone, display brightness, sync, etc. Way too many factors.
As for me, I get about the same life on most ROM's I use after letting the phone settle for a few days. The only constant I have is the kernel I use which is in my signature. Lately, I've settled on one ROM as the dev is on top of his game with this device. That ROM is also in my sig.
