[Q] [i9000] Root my phone to calibrate battery ?

hello. i'm faced with a problem: i have my i9000 for about 1 year; never rooted it; only update my operating system 2 times via samsung kies when i got the message that a new firmware was available while connecting my phone to my pc (now i have PDA:JS4 / PHONE:JPY / CSC:JS1 (ORO)); and for some time now the phone discharges very fast; lasts about 8 hours; i use it at a medium pace: making phone calls, writing sms and replying on messenger if someone gives me an instant message and every now and then i listen to some music when i'm going somewhere, besides that i don't use it much; and i don't have programs running in the background except for the accounts sync system for yahoo mail, gmail and yahoo messenger. so i decided to recalibrate my battery to see if it lasts longer. i got android terminal emulator from the market but the problem is i don't have access to delete the batterystats.bin since the phone is not rooted. so here are a few questions:
1. should i root my phone just so i can delete this file ?
2. which of the 2 methods works best for battery recalibration ? the one where you charge your phone till 100% while it's on then switch off and charge some more ? or the one where you let the phone die and the charge completely while it's off ? (i ask this because browsing the forums i see everyone saying a different thing about this topic)
3. if i decide to root my phone to be able to delete the above mentioned file, should i install one of those user made operating systems (i think they are called ROMs) that has a lower battery consumption rate ? (i don't know how to do it but i think i can manage following the tutorials on this forums). i saw in a poll that darkys operating system has the lower battery consumption. is that correct ?
thanks for reading this long threat and taking your time to reply to it!

1.) I would do so. With root access you do much more cool things.
2.) In Darky's forum (darkyrom.com) you can find a good manual for calibrating.
3.) Custom-ROMs have some features stick-ROMs don't have. At the moment you have a branded phone (branded by Orange?). Some ROMs need quite less battery (Juwe's for example).

- Now use your phone until the battery is flat again and charge full (no need to have it turned off, unless you it to charge faster). Repeat 2 or 3 times and your battery will be calibrated
- Only wipe battery stats once, run a few cycles of full charge / discharge and after that just use your phone as normal (i.e. no need to deplete / charge fully anymore).

[Q] Working for better battery life

Hi all,
I've been working on getting my XT862 to give me more life on the battery. I've rooted and debloated using psousa's stuff, but I'm still not where I'd like to be. I've noticed a few interesting things:
AOS is showing as the top user in the battery monitor. Currently it's at 32% with my display and WiFi bringing up the rear.
Even though I've run the debloat script as root and confirmed the rename of skype.bourbon and motoprint, these things still start up. How is this possible?
BetterBatteryStats shows that the suspend process is my main battery user. How does one fix that?
Any advice on what to look for?

best route is to install a custom ROM and try different ones out for battery life. I would suggest Maverick ROM also make sure you wipe battery stats after installing a new ROM and fully cycle your battery.

I'm guessing suspend is another way of saying System Idle.. if you wanted to get rid of that, make a nandroid backup of your system (via bootstrap or safestrap) and experiment what system apps/services you can freeze (via Titanium Backup) without getting force closes on the stuff that you use. I have about 30-60 system apps/services frozen depending on the ROM that I run. I have no force close issues, and my system idle uses about 1 percent of the battery per hour.

Additionaly, if you are using the CDMA network, force CDMA mode, likewise from GSM/UMTS, if you are using it, force it, do not use Global, as it will have both radios running and searching for service.
Disable the use of wifi when you aren't using it (there is an option to auto turn it off when the screen turns off, however this may cause worse battery life if you are using data as it will try use your mobile network, requiring more power), if you wish to leave it on, increase the scan time interval (i made mine 10 mins, up from the stock 45 seconds)
Auto brightness (it isn't really that bad...)

And get the app called juice defender. Once you set it up it controls all of your wireless stuff. Like turning wifi and 3g off when you turn your screen off, etc.

If you use Wifi often, it is a good idea to check your Wifi Sleep Policy. To do this, navigate to:
Settings > Wireless & Networks > Wifi Settings > Advanced Settings (hit menu to access this) > Wifi Sleep Policy
I have mine set to 'Never'. By default, it was set to turn off the wifi when the screen went off, so any background apps that run and use data default back to the mobile connection. When you turn the phone back on, it turns the Wifi back on from sleep mode. By changing the sleep policy to 'never' you prevent this disconnect/reconnect to Wifi cycle.
This helped my battery life when connected to Wifi. Let me know if it works for you.

Thanks to all
Thank you for your replies everyone. I'll have to get TB and start freezing stuff. What confuses me though is how a service like Verizon Apps or Skype Mobile gets started even though it was renamed ".bak" by psousa's script. Also, I've noticed that when I run the restore bloat software, I don't get back all the apps in my app drawer. I'm not sure why that is.
Is it possible something got screwed up if I ran the debloat script twice? I see that it does a bunch of mv proggie.apk proggie.apk.bak type work. If the first file wasn't found, is it possible that it overwrote the .bak with gibberish?
My WiFi sleep policy is never because I have WiFi all day and I like Google Talk a lot. I'd be happy if I could get WiFi/Display as my top users, just AOS seems like a bug.
I'm on UTMS so it's forced to that all the time.
Maybe the answer is to try the mods. Or maybe SBF to the stock and try again?

[Q] "Android OS" Taking Up My Battery

I have used the Droid, Ally, Galaxy S, Galaxy Tab 10.1, Droid X and many other Android devices without this problem. This phone is different. Android OS has been taking up 25-30% of my batter with everything I do. Complete restore, update, custom roms, etc, nothing works. I averaged on my other devices well under 10% of my battery being used for Android OS, but this one uses a crazy insane amount and my battery is dead in 7 hours on 3g only mode! What's the deal?

That is a lot. The most i have seen is like 10%.

I only have 4.5 hours of uptime right now, but mine shows 4%.

4% here.
You have something installed that's using the "os", or some app that relies on a service that is now gone.

if Android OS is that high then you're basically doing nothing with your phone.
Try watching a NetFlix video for an hour, or else playing a game, etc.
You have to realize that your phone never actually turns off (else you'd never receive phone calls ) so that the OS has to be running.
If you're doing nothing, just letting the phone sit there idle, then of the 5% of the battery that you let it take up while you were waiting to see if it went down, 30% of it was consumed by the Android OS. It makes sense if nothing is being used that hte OS itself will be the largest user of battery, b/c, as I mentioned, the OS is still running, even if in sleep mode.
And, TBH, it actually made more sense that the old way of reporting Cell Standby was taking up 'so much' battery - b/c if the phone is idle, then I expect that the phone call monitoring aspects of the OS would take the greatest amount of battery, b/c nothing else is using the battery.
You have to take what you see in battery usage with a grain of salt. If you're not using your phone and you see a 3rd party app taking up 40% then you have something to worry about. If the OS itself is taking up that sort of percentage, it means nothing else was running ot take up the battery.

I agree with John that non-use will cause OS to seem abnormally high.
However, your 7 hours of battery life is terrible:
If you are having short battery life here’s a list of things that can help. Just read through the list and select the items that fit with the way you want to use your phone. Not all items will work for everyone and this list was written for the Droid Bionic but should work for your phone too:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- When you get a 1) new battery, 2) do a factory reset, or 3) an OS upgrade - run your battery all the way down until the phone shuts off and then charge the battery all the way up. This will calibrate the phone's understanding of the battery's capacity. Do this once every month or two also, but don't do it too often if you can help it.
- I have my battery set to "Performance Mode" and data is on all the time because I am on call 24x7. If you don't mind, try out a more conservative battery profile to save more gobs of energy.
- Set screen brightness to "Automatic"
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
- Turn on Bluetooth only when you are going to use it.
- Consider turning off voice privacy. This may not be a big deal but it will save some processing (and therefore battery). It may also improve call quality.
-Turn off haptic feedback, animations, and any un-needed sounds in Android settings and in your apps
- Set your screen timeout to as low a time as you can stand (I use 1 minute) and manually turn the screen off when you’ve finished using the phone.
- Turn off in-pocket detection. In-Pocket Detection has been the source of many issues already.
- Keyboard: turn off vibrate on key press and sounds for any keyboards you use
- Use a red or black screen background. On the original Droid screen--not sure about this Bionic screen--red was the most efficient color that could be displayed.
- Camera app: I like keeping location on and flash on auto. Consider turning location off or at least returning to the home screen ASAP when using camera if location for camera is on.
- In stock browser the default home page is Google and it uses your location. This is a bad idea as it can waste your battery for no reason. Make something else your home page and make sure to close any web page that uses your location when you're done viewing it.
- Charge your phone via the wall charger instead of computer USB as it is faster. Also, don't use long USB cords--use regular power extension cords instead. I stick with the charger that came with the phone. Put the phone on charger when you go to bed every night.
- Consider install the Home Replacement app Zeam. It is basic app that uses very few resources and will help with battery power.
- Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail.
- If you are using Live Wall Papers, stop!

If battery life is still bad: Consider doing a factory reset: These have gotten pretty painless lately by following these simple steps: 1. Make sure Backup and Restore are checked in the Privacy setting. 2. When going through the setup after the reset, turn on wifi as soon as you can (assuming it is available). 3. After you have entered your Gmail account info, you will be presented with a screen that has two check boxes. Basically they are "Do you want Google to backup and restore this phone”. Make sure you check both of those. Your apps will then automatically reinstall (paid and free). Set the phone aside for a minute or two and let the apps download and install. 3. If rooted, use an app such as titanium backup to restore data only to select apps such as Tapatalk and you will not have to re-enter all your login information. I do this for 3-4 apps (Tapatalk, SPB Shell, etc.).
I've been flashing new roms/updates about once per day lately and I can be up and running with all my apps and settings back in place in less than 20 minutes. It's pretty painless now.

When I first bought my Bionic, it was eating up battery like crazy. After 2 replacements phones, I found out that some Bionic's were having an issues with Draining battery. My 3rd Bionic is great. On my original Bionic, it would take me 2 extended batteries and still could not make it through day under moderate use. Now, 1 extended battery will last me all day with heavy use.
There are some faulty Bionic's out there. It was even mentioned on Droid-Life. I think the original one they tested had issues with battery drainning really fast.

That is weird. I wonder....could it be due to actual batteries as opposed to the phones?
But in the OP's case, I doubt it - it would be too coincidental that his battery were to fail right as he applied the update.
@OP - you might also try conditioning the battery, fully charging and then running it down a couple of times and seeing if it stabilizes. It might have to do with the update wiping the stored battery stats (long shot, I know, but still)?

Battery drainage on Galaxy Note

Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.

That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

Fully agree.
I would get 4 to 5 hours of continuous use, I reckon. Some people report more.

I think the problem is with the battery. you can try this :http://www.amazon.com/2600mAh-Batte...I84K/ref=sr_1_4?ie=UTF8&qid=1329085625&sr=8-4 . Just bought it and it give me like 6-7 hours of watching videos.

Thank you for the link. I was looking for a better battery. I home to find a vendor that ships to France though.

Thank you

Thank you my dear sir, I'll take that as the second option, I'll try getting a new battery since my warranty is vailed for 2 years.
Thank you though

No need for an extra battery or extended battery.
Install juice defender
Leave brightness on auto
disable 3g (it is on by default I believe and I noticed a big savings on batt %)
disable auto screen rotate(optional)
my phone is @ 44% left , lasted 11 hours 2 minutes , This will last me another 5-6 hours.
Did about 1 hour of gaming (myth defense)
30 min browsing on wifi
45 min on tapatalk
1.5 hours on the phone
1.5 hours streaming music to my desktop via kies air

I had posted something like this before...
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity

Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.

Four issues: Dialer, camera, charging and flashlight.

So I have four issues with the nexus 6.
Using stock ROM, not rooted.
1. The remaining charging time shown on the phone is incorrect. It normally takes around 30min more than it states on the lock screen. Using the provided turbo charger.
Battery life and charging is not a problem, the information is.
2. My dialer, or better yet, calling capabilities, don't work sometimes, I need to reboot for it to work.
3. Camera stops working and says: Can't connect to camera. I need to reboot to make it work again.
4. If the flashlight is turned on it turns off automatically after like 15sec and the icon disappears from the quick setting menu. Need to reboot to make it work again.
Anyone else with these issues?

1. that is just an estimate. your phone changes how much voltage goes in when charging, with much less voltage going in after 90%. your phone doesnt count this. it estimates according to where you are in the charging cycle.
2. no idea, havent seen that before.
3. casn be an app or a hardware issue. if it keeps happening, even without any apps installed, id get it exchanged.
4. seems like your phone has a hardware issue, id get it exchanged.

Well, been checking up on things a little, and the dialer problem seems to be on Googles part: https://code.google.com/p/android/issues/detail?id=82949
I think the camera issue as well.
I thought about the same thing with the voltage, since it's a turbo charger, however one would think that it's a thing that could/should/would be implemented on a phone with quick charge technology.
Will try with another non-turbo charger.
The flashlight I'm not sure about, will wait for another update for lollipop, if the issue is not fixed I'll change the phone.
