[Q] is rooting always like this

Maybe this is due to my lack of experience, but maybe not. It seems like every time I put a new ROM on my phone it goes to hell in about a month. I'm not a technician but I can follow directions for installation, patches, etc. So far I have had 0 long term success in installing a ROM that ends up being any better than stock after 30-60 days.
For example, I've had issues with battery drain, random booting while the phone is powered off, redraw issues, serious lag, data connectivity issues, and a few other things. It seems like its always something.
The only phones I've toyed with are my old Eris and my Charge. Is this a phone issue, noob issue, or is this par for the course? If it is par I'll end up back at stock and have mediocre performance rather than have a buzz saw that ends up needing constant tweaking and maintenance.
Btw this isn't a knock on developers. I appreciate them sharing all their hard work. I just want to know if everybody else goes through this or am I holding a bag of stupid.

Just rooting does nothing more than give you superuser access. It doesn't even do anything that uses the root specifically. Different roms do different things, but nothing to use battery...mostly they take things out rather than put things in.
Best thing to do is look at BetterBatteryStats and track partial wakelocks. That will tell you what is waking up your system and if there's anything spiking it, you can deal with it. Most of what really drains battery on this phone, other than bad apps, is somewhat random, and it will affect non-rooted phones just as much as rooted.

Must be something you did, picking a good rom make a big different. In my case. I flashed tweakstock to my daughter's phone since the first day it released (with tweakstock kernel), and never, I repeat never have any issue, when tweakstock 1.4 released, this is the second time I touch her phone and up until now she hasn't have any issue. If you use eclipse rom, PBJ kernel, Imonsey kernel, you're going to have issue. They are not bad roms or kernels, but they do have bugs. This is my experience.

Yeah, I think it's you. On stock, I'll be lucky to get 12 hours usage in a low signal environment. On a custom ROM, with custom kernel, I'll make it through the day. Of course, I've had a couple of random total crashes where I had to go at it again, but I deal with it.
PROTIP: the Facebook app needs to be told to stfu constantly. I would get an app like System so you can kill it easily-it still stays in RAM and in wakelock, taking clock cycles, even if you close it by backing out. I found that this was one of the best battery savers.

Yes, I agreed with kvswim, Facebook is a big battery drainer, I ended up using the browser for facebook, it's not as nice as the FB app, but once you get a hang of it. It's fine. I suggest if you want trouble free, ODIN pit file and original factory image, then upgrade to tweakstock with tweakstock kernel, then install Go launcher for smoothness. To save battery even more install battery saver by Antutu.(keep all default settings, don't play with it). You will see big improvement with both battery and smooth trouble free phone.

you really find a battery saver to be helpful. Every time i try one it ends up costing me more battery life than it saves.
As for the phone issues. Are you wiping data, cache, and dalvik before you flash? Not doing so can really muck things up. And a lot of times its just an annoying app that sucks up all ur juice, ie words with friends and facebook. I use them alot so I deal, but u can definitely tell the difference when u dont have those apps installed.

No i dont think its u...i have problems also.i jus made a post about my home/hard key...its always seems to b something after the next.but it looks like people find ways to deal and eventually conquer.also i appreciate wat the developers do.its alot of work and headaches.on top of posting and replying to many many people.its the roms that cause problems...constant tweaking and toying around...alot of times things jus need to b debugged a little it seems.but its all in the nature of what were all doing here.good luck to u

Hey. how about give the "battery saver" app by Antutu a try. This is one of the kind. It does not kill processes like others. It actually readjust cpu frequency during usage and put your phone in heavy deep sleep, after installed, let it run for 2 days, you will notice at least 3-4 hrs more during usage and 10+ if you let your phone sleep. I have test this app with wifi,4g,gps on 24/7 and I still have good battery life.

I downloaded betterbatterysaver to check my stats. Now to figure out how to read the data. Any suggestions? I've searched Google and it seems to be a mystery for many. It appears that Dolphin HD is using most, but I kill the program when I'm done???? I switched to mini and froze HD to troubleshooting. I only use FB browser too. I ditched the app long time ago.
Before I flash I wipe dalvik cache, data, and then wipe it again. I follow directions closely since I can't figure my way out if something goes wrong. I'm running tweakstock's latest right now and I'm really enjoying it. Very stable and snappy. However, the battery problem is killing the experience. It drained fro. 69% to dead in 6 hours overnight! Switched from 1.1 because the phone got very laggy and the hand off between 3-4g was getting dropped and I was losing data connection.
I will try the battery saver app. Just got battery calibrated and still not any better. My need to have a phone that doesn't suck will keep me playing with this thing until I get it right. My Charge is used so much it's like my third hand.

Did you try to disable(freeze) SDM app and also Google service? May need to backup all your apps and do a factory/data reset, If not help, possible to re ODIN factory image (see pos # 5) since you have data drop issue. Some thing is mess up in your OS.
For betterbatterystats look at wakelock and see what process used the most.

If it died overnight then something is definitely eating your battery. Are you in a low signal environment? Go to settings, about phone, then battery usage. If anything besides display is taking more than around 5-10% (can be more if you use it a lot) then that's your main problem. If your cell standby is more than 25% it's the low signal that's killing the battery.

Data is up and running smooth after flashing newest tweakstock. My home has a strong signal and my bedroom is sometimes 4G so I don't believe the signal was low, unless the transition between radios killed it. However, it wasn't a problem 3 weeks ago.
I did freeze SDM and noticed some improvement. Buhohitr, did you mean freeze Google services framework?
Battery usage seems to be normal for now. I am noticing Dolphin is no Singer sucking down 35% or more since I switched to Mini. It doesn't even show up on the list.
I'll see how it goes today and report back on wakelocks. If it doesn't get any Beyer ima Odin to stock and root/flash tweakstock again.
Also, the battery doesn't drain unusually fast wile in use, browsing, music, etc. But when it sits it drains at 3-4% an hour.

I would try manually calibrating your battery. It really worked for me. On average I get about 18-19 hours on one charge with medium to heavy data usage throughout the day. There is a thread in the General section.. I'll post a link in a little bit.

Wiping battery stats is a complete placebo. All the battery stats stores is the state of apps as related to various things that affect battery life (like display on time, screen brightness over time, and wakelock states). It does nothing that will actually affect your battery life one iota. It is actually cleared every time you charge your battery to 100%, so manually wiping it is completely pointless.

I'm well aware of the post of Dianne Hackborn debunking the myth of wiping the battery stats; however, if you actually read the post on the steps to calibrating your battery, it's not just wiping your battery stats. There's actually a few more steps involved. You're right though, if you just wipe the battery stats and expect better battery life you're just wasting your time.

To disable Google Service, go to settings -> location&security and uncheck Google service. Do not freeze Google framework. Also seems like your phone is not in deep sleep, please install "battery saver" by Antutu and let it works for 24 hrs, you should see huge different when your phone is sleeping. BTW what kernel are you using? If you're using PBJ kernel you can install "CPU tuner" to further keep your phone in deep sleep. I'm talking about 1% for 3 hrs sleeping.

I'm curious as to what Battery Saver actually does. The app's market page doesn't say. I'd be curious if it would interfere with my IMAP push email or SetCPU's overclock settings.

I've done that and never seen an actual difference. Like I said before, I have no reason to believe that any of it is anything other than placebo. My normal daily variability in use is more than enough to account for any perceived differences. On top of it all, bump charging is not good for a Li-Ion battery, so if anything, those instructions are a good example of how to lose long-term battery life for short term gain.

Personally, I believe that most of the time the procedure does nothing. I think there are times, though, that corrupt data gets into the battery stats. For instance, I had an app lock up my phone and force a hard boot. When the phone came back up, it showed 22% more battery than it had previously. I believe that bad data such as this can over time affect how Android reads your battery life. In that instance, I believe clearing battery stats would help. I don't think doing it just because a new ROM was flashed actually does anything, though.

What roms have good battery life?

I'm currently running Valhalla final rom and it drains my battery very fast with even minimal use.. I aslways have GPS and wifi off. Always quit all my apps and free the ram when I'm done... any good roms out there with good battery life?
Sent from my SGH-T959V using XDA

I get 2-3 DAYS with valhalla final, so I'm not sure that swapping roms will change your battery life much. You can try one-click gremlin remover before you flash your next rom of choice though.
also, do you have any apps/services that run in the background, like facebook?

+1 to Mike
Alex - there are several recent threads tegarding battery life in the Q&A section. Browse them and see if you can learn a few things how to improve battery life and what the big battery drainers are.
All the ROM's, for the most part, have the potential for great battery life if you use them correctly. WiFi, Sync and GPS need to only be on when you need them. Many apps sync on their own - adjust the sync intervals on them. Use Gemini App Manager or AutoStarts to disable autorun scripts in the apps. Adjust screen brightness. Any data hungry apps (i.e. music streaming, Netflix, etc) will drain your battery regardless what you do. Undervolt with Tegrak Premium. Minimal widgets on home screens.
It is not the ROMs - it is how the end-user uses the ROM and their phone.

Turn off data and background data, until you need it. I get over 2 days sometimes depending on usage

Im running NO widgets, no facebook sync.. the only account that syncs on my phone is gmail... nothing extra downloaded really just mostly valhalla final rom with a few apps.... Im noticing a big difference in battery life from stock gingerbread... I know for a fact that my battery is good because i was always able to use it fully for one day.. i dont charge my phone often to keep battery health in best condition I charge only when its super low.. and once in a while I let it die completely then recharge it fully
I even see a better life on icbinb rom than valhalla.. just wanted to see if anyone else notices the difference guys

You saw Mike says he gets a couple days on Valhalla. Try the Gremlin Remover. Do everything the thread says. It is effective.

Stop doing this. Li-ion batteries are a different breed.
I suggest taking a read over this page.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
In brief stop treating your li-ion battery like its a ni-cad otherwise you will never have good battery life.

Last run was for 5 and half days with about 3:30 of display time (internet and such), 1:30 of music streaming and like 20 min of voice calling on stock rooted and debloated KJ6.
Yup, I know, for 5 days that's not much of a usage but point is that SGS4G does not use too much juice when idle.

I keep GPS and Wi-fi on all the time, use the phone pretty hard during the day, and still have 60-70% battery left each evening.
You say that you "quit all my apps and free the ram", so I assume that you are using an app killer. My experience is that they are actually detrimental since they aren't needed and many apps just restart in the background, sucking more battery.

Omg people...your using an android....you want everything at your finger tips and wonder why it eats battery
Try all this while on your laptop without plugging it in.....just get an external charger,and a few extra batteries....all in which are very cheap now.......and then we dont have to listen to all this over and over any more.

Ocane 3.0 from Raver. It lasted 3 days for me w/o charging

Is anyone else getting massive battery drain?

Since I upgraded tp 4.0.4 my battery life has been completely terrible (nexus s GSM, stock, latest glados kernel) even though I don't use it the entire day, it drains over half in about 4 hours. Anyone have any idea what I can do to fix this? It was perfectly fine before the update and would last days if I didn't use it, and about 12 hours if I did. Right now it's just unusable.

BetterBatteryStats and/or a fresh install (data/factory reset, format /system, optionally format /boot, install ROM).

Are you using a custom ROM?
I've had the same problem when I was in stock 4.0.3, which is why I decided to root my phone and resort to custom ROM's and kernels. Now my phone is doing ok in the battery department and is also much more snappier and smoother. Oh and most custom ROM's are already using 4.0.4 anyway.
Let's try and be scientific about your problem, here are some things you may want to try out first to improve battery life:
turn off wifi when not in use
turn off automatic syncing if you don't need it
set your network mode to 2G only if you're not using the internet
turn off mobile data when not browsing/using the internet
install the watchdog lite app/widget from the Google Play store so you can monitor rogue apps that are sucking up juice
do not set your screen brightness to AUTO, but manually adjust it when you need to. you can do this either in the settings menu or thru the power control widget
This are the things I can think of off the top of my head. If this doesn't improve your battery life, even just a bit, you may have no choice but to resort to drastic measures....and go to the dark side.
Hope this helps! Cheers!

mine is okay
Batt I think it quite good on 4.0.4. I can get about 23hrs of usage. Some wifi, some 3g (fb, whatsapp, updating apps, email), some music. Stock ICS.

I had this issue after stock 4.0.4 update from 4.0.3.
I found mediaserver using more battery than it should, so I;
1) Copied all files and folders from /sdcard to PC
2) Re-format /sdcard
3) Re-store all files and folders back to /sdcard
Mediaserver process is now minimal and battery is good again

Ok thanks for the suggestions guys, reformatting my phone would be alot of effort on my part due to how much time I spent setting it up so I would like to use that as a last resort.
I installed battery stats but I can't decipher what it's saying so if someone would be as kind to explain? I took screenshots of everything in an album and I would really appreciate it if someone had a look in the album below.

Well for one, you have chunks of bad signal(red bars). That right there can kill a battery quickly. The other stuff you may be better off saving the dump file and posting it as an attachment over at the BBS thread. The guys over there are pretty informative and may be able to give you more stuff to look at to help you out.

The red bars are when I was using the underground, the battery drains just as fast overnight. I will look for that thread, thanks.
Edit: I do not stay on the underground overnight, and I have a good signal in my apartment (you can see it's fine when I arrive)

yep...a weak network signal will drain your battery a lot faster. if you're not using it to text, call or surf, or if you're just going to play games, might as well go airplane mode for a while, or at least until you get above ground where the signal is stronger.

After a good couple of hours not using the phone in a good signal area create a log and post it. Preferably get the hours just after charging.

Please someone take a look!!!

I'll have a good look tomorrow with some suggestions. Had a fair bit on the last couple days with minimal internet access.

What ROM and Kernel are you using right now?
There are a couple of interesting details there but nothing that i can point out that will take you from 100% -> 30% in that time.
Some things to test:
-Turn phone off (noting charge), remove battery, replace battery, leave phone off overnight and turn it on in the morning, again noting the new charge
-Keep data off and see if battery is still draining / Airplane mode
-Uninstall half of your apps and see if it still happens. If not, add half of the apps you uninstalled. If so, uninstall half of the apps you have left, and so on.
-Do a clean install and try for 2 - 3 days, see if it still happens (preferably a stock ROM, preferably from fastboot images)
-Attempt going back to Gingerbread and try for 2 - 3 days (preferably a stock ROM, preferably from fastboot images)
These steps can (and should) be done pretty much in order and will rule out ALOT of possible reasons and give possible solutions some merit. Let me know how this goes.

Using latest stable cyanogenmod + tried glados and netarchy and matrix kernels, all the same result. Will try what you said, also I bought a replacement battery to see if the actual battery is faulty (weird because it used to be fine). As for the airplane mode thing I already tried that, to no avail.
edit: should add that was using stock 4.0.4 before cyanogenmod.

[Q] How to increase battery life?

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?

Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn

ahh ok thanks guys ill do what you guys said and see if it helps

you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.

no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Download Gemini from the play store and manage the autorun for apps. That's what I do and it saves quite a bit of battery

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.

If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.

[Q] Battery drain and high Android OS usage?

Last week I got a Droid Ultra and am noticing my battery life is pretty bad. I'd heard the Ultras don't get great battery life to begin with but I think something else is going on with my setup. My Android OS usage is always by far the highest, dwarfing the screen percentage. This is my first smartphone so bear with me if this is normal or I'm doing something dumb. My usage seems to be pretty normal by these board's standards, 30min talk, 20-40 texts, wifi on, and couple hours of gaming. (slow week at work!) I have installed Watchdog and it is running on moderate, although I must admit I don't really know how to use it to its full capabilities. I have attached some screenshots below, any advice would be greatly appreciated.

I have a Mini with the same issue. Still haven't figured out what it is, even tried a factory reset. So you're not the only one.

Did you guys try disabling the bloatware and turn of Google location?if you're still on 4.2 you can use gsam battery monitor from play store. It gives detailed info on wakelocks and and what's keeping your CPU active.

I have tried to get rid of the bloatware but they don't seem to be removable. I can stop them but they just restart later. I have just turned off locations so we will see if that helps. Will the program you mentioned work with Kit Kat? I am using DU Battery Saver at the moment. Thanks for the advice.

Gsam Won't work on 4.4 unless you're rooted. So you can disable the bloatware easily. Go to app drawer long press on app you want to disable as if you were going to add it to the home screen. Drag it up and drop it on app info. You can disable it there. Some apostle it will ask if you want to revert back to stock. Select ok. Best part is you can't break anything this way! If you want to enable the apps go to settings....apps...and slide all the way over for list of disabled!

Bloatware has been gone for a while. I tried disabling location last night, but still have the same high OS usage today. Just installed GSam- on 4.4 but rooted- I'll post if it comes up with anything helpful.
