Hello everybody, My photon is having very bad battery life and i havent even had it a full year, And when i first started having this problem i got a new battery, ( no luck), I fully rebooted my phone, And i rooted it, So if anyone has any suggestions on how to find whats causing my bad batter life tell me.
Batterlife:
Playing games 1-2 hours
Listening to music 7 hours
Screen on listening to music 3 hours
bump, Please help!!!
12 hours is a great battery life.
so? 6 hours of display = it's normal time for android phones..

Question for ya. Are you running any custom roms or just stock rooted?
The reason i ask is simply because if you are running any ics+ roms, your battery life odds are will be significantly decreased, its like that for phones who even have official ics/jb
If your on just a rooted stock rom, odds are the bloat ware is draining your juice. Sprint/moto have a bunch of background apps/services that will run at startup.
Few recommendations for you.
Settings:
1)Turn off auto brightness, and simply set your phone to a brightness that is low, but easily visible indoors/out
2)Ensure gps is off unless you are using a navigation app (please dont use the crap one built in, drains battery, lags, is rele only a trial,etc)
3)If you are not in the habit of locking ur phone when you are not on it, set your timeout for the screen to 15 seconds
4) Turn off background sync/ use only on wifi
Apps:
1)Download a root uninstall app to remove apps.
2)Download a autorun management app to disable unnecessary crap
3)Possibly buy a nice root toolbox, ie, rom toolbox pro.
4)Use battery calibrator for root phones and follow instructions
Aftermarket:
1) buy an extended battery
2) buy a spare or 2 batteries. (look on amazon, buy the two aftermarket batteries/wallcharger/ Lanyard) Youll never need to worry about your battery again. lol
3) Buy an independent charger/power source, you know, the ones that you charge, and then use to charge on the go without any wires
None of these things are guaranteed to help, but thats what i can think of off the top of my head as far as solutions go. The photon has a surprisingly small charge battery considering all the phone can do.
Hope something here helps at least a little

My apologies for the delay in my response. I haven't run the stock rom since week 2 of me owning the phone. That was quite some time ago.
i will link you to a very old thread here in the development section that i used to remove all the sprint crap.
http://forum.xda-developers.com/showthread.php?t=1217134
Keep in mind it is a good idea to ensure you know how to revert back if need be.
You have 3 options here really, i will list them in the order i recommend
1) Get yourself either that toolkit i mentioned(Works good for all of your needs) or a root uninstallation app that offers you the ability to backup/restore/freeze apps
2) Use a file manager app with root privileges to browse your phones system files, and rather then deleting the apps, simply rename them with an easily recognizable extention, IE: .backup, .bak, .back (You get the idea)
3) You can delete apps manually as instructed in the thread, be sure you read it thoroughly, and know what apps you delete disable (google search the apk and what it is if you are unsure)
Good luck mate
Ive Pac'ked my bags, and am on my PacMopho. *Cheers*

I know battery life issues have been talked to death but...Here's a new perspective:
so I have been doing some experimenting with my amaze in terms of battery life and asking my friend who works at T-mobile regarding his SGS2...He says his battery life seems to be pretty crappy too, marginally better than the amaze....so, I hard reset my phone and I did not sign into google, left my phone on airplain mode, basically I did not set up anything...I turned off wifi, and data everything was truned off...I went for 10 hours with only 2 percent battery drainage...then I signed into google....and in a matter of 10 minutes I went from 98 percent to 92... Watever is eating the battery up is not the phones hardware fault or the screens fault... I turned off background data sync and it seemed to make little difference...It seems the google programs or any program that needs internet connect regardless of syncing or not will have significant effect on your battery life...between 4g and wifi I saw little difference in battery life drainage...my phone signal is completely green so I cannot blame the signal... I cannot possibly kill gmail, market, maps etc...these are programs I use constantly...lets hope with the ICS update some of these sofware issues will resolve...
google needs to start managing applications better and not leave a bunch of applications running in the forground and background...
I've heard different theories regarding task killers...some say it actually worsens battery life since programs keep wanting to restart and some say it saves battery life...can anyone elaborate on this? I have juice defender ultimate, it seems to make minute difference in battery life as well.
PLEASE MOVE THIS THREAD TO GENERAL MY APOLOGIES
Display is the biggest factor obviously and then its data transfer or anything that has to do with transmitting signal.
like every other phone the 100% lasts for a long time then after it drops it drops quickly. So your analyses is flawed since it already dropped from 100% and then you switched data on. There are apps that are constantly sending data and the sense UI kills the battery a lot too. Thats why AOSP roms are better for battery life.
Juicedefender helps
setcpu helps
managing your apps helps
changing your background to black helps
I've tried juice defender, um... I would suggest you read about instructions on flashing a custom ROM I'm on quiksense and when 2.0 comes out I heard xboarder's got some really nice improvements with the 1.4.1 version I almost doubled my battery life. My phone used to go down to 50~60 idle over night, now it's about 90~ idle over night.

Juicedefender did help but then I was missing all my google talk messages, google voice messages, google voice voicemails and a bunch of stuff...ever going through the settings and setting it up to recheck background data every 5 minutes did not work with J/D...so I stopped using it...I need my data to come through...whats the point of having a phone if you can't get notification and use the features meant to.... I used to be a strickly no bloatware simplistic out of the box google experience guy...thus my nexus one...I LOVED IT...then dropped it and not worth fixing. nexus S was dissapointing, so is the galaxy nexus...I hate all the bloatware, and all the customizations t-mobile makes to the phone...like t-mobile inscription on the phone, t-mobile startup screen...etc...yes I know I could root and change all that stuff...honestly I just don't feel like going through all that crap!!! and also void my warranty...I don't undestand howcome the iphone is never branded!!!???/ wtf....I buy a phone and it's mine why does it have to come with a logo of the company....IT'S MY PHONE. THEY SHOULD INSCRIBE MY NAME ON IT. as for the bloatware I figured out how to temproot and freeze programs... I don't think you can change the startup screen to the original HTC one with temp root...damn T-mobile...you used to be so much better...

use JD ultimate and set the apps to work with screen off.
you can get a telus or wind model without the tmobile branding
i think you can change the bootanimation with temp root because it's just a file? I'm not exactly sure about that one though.
apple sells their iphone to ATT
as htc sells their phone tmobile
tmobile probably request a branding on it with a higher cost.
att probably reject the higher cost because they're already losing money when buying the iphone from apple (i think i remember i read it awhile ago) and make money off data plans.

I did use JD ultimate with those apps enable, NO GO, MAYBE I SHOULD RESTART AND GIVE IT ANOTHER TRY...its only when that program requests it that it can initiate the data line, otherwise if someone sends you a text i will not get it since both wifi and data line are cut off permenantly during screen off that is how it saves battery....enabling programs are good for things such as pandora etc...once they end a playlist or something it automatically turns off....this is what I understood from the explaination...i temp rooted and removed some bloatware...hopefully I can change the startup screen as well, perhaps through adb push
P.S. where do I download the original HTC boot animation and sound and what folder is it in to push into? thanks

for JD you want to click on the app thing twice so it goes to enable/screen off not just enabled. But yeah i noticed that sometimes it works sometimes it doesn't
not sure where the bootanimation and sounds is it at, i never played with it. You should check out the themes section, you can download the zip and browse through where it goes.... other than that there might be other threads with the instructions on where it's at.
You may want to try an AOSP based rom, (if you rooted)
I was getting 18 hours of use with 36% left, Medium usage (ie browsing, texting)

ya i clicked twice enable/screen off...still no go for those particular programs i tested and tested it....oh well..my batterly life is not bad at all...besides I have a car kit which charges it in the car. once i started using the thing tho, battery drains fast...its no mystery its got a big screen bigger than my old N1 which used to be amoled and this is lcd...also this uses 4g which consumes significantly greater battery...faster processor etc....its not a mystery!!! they need to come up with a new battery technology soon!!!!
I have an old Nexus One doing nothing and was thinking of using it as an mp3 player.
How much of the android os can I remove to basically just have it functioning as an Android mp3 player?
Removing the phone functions and other apps should give me extra battery right?
Lol just buy a mp3 player.

And where will the fun in that be?
Stripping down the system can help you learn about how it works, and skills and experience you'll gain may serve you, long after the device has been recycled.
This is why he has posted the question in a developer forum, and not a fan one.
On topic
Seems like a neat idea, but as far as removing the phone functionality to gain extra battery? Why not just use Airplane mode? You'd never know when you might need just a phone.
Other than that, I'm sure that you can remove most of it (the apk's that is), and i suppose you could make a script to startup Music.apk upon boot.
I know that the emulator is slow on most normal PCs, but I'd advise trying what you want on the emulator first, just in case. You can even make a list of what you are removing as you go, so you'll know what can break the system, and what isn't going to have any effect.
Thanks kurdo_kolene didn't think about airplane mode!
Think I'm going to have to play around with this the weekend to see what can go and what has to stay!
My nexus one has a broken power button so swapping out the sim cards is not possible unless I have a charger to power it back up. So I had no plans of putting a sim card in it but since airplane mode should shut all the radios off it should be fine to leave the basic phone functions as it is.
Just flashed [ROM][AOSP][2.3.7] OxygeN1mod FINALE! [2011.12.10] which already is pretty barebone
But I went about removing apps until it wouldn't boot... But it still boots
59mb RAM used / 315mb free on boot.
Launcher has just 4EXT Recovery, Browser, Downloads, Market, PowerAMP, Root Explorer, Settings and Superuser!
Removed all the phone, contacts, sms/mms, calendar, email the lot and all is fine.. Expect when I removed the Phone.apk and had to reboot but no problems since.. Will have to fully charge the battery and see how long it will play music constantly now!
I would guess that a big part of those 59 MB is allocated to the dalvik runtime. I've used DSL on an old PC and after boot it used 25-35 MB RAM.
Pretty impressive nontheless.
If mplayer made a native version for arm devices, that could be used without a launcher, that would be even better.
You might want to install Android Terminal, in case you need to reboot and you're away from the PC.
Thread moved to Q&A due to it being a question. Would advise you to read forum rules and post in correct section.
Failure to comply with forum rules will result in an infraction and/or ban depending on severity of rule break.
Yer sorry mods I see the other forum after i posted but couldn't find a way to move it myself...
Anyway I was planning to test the standby time but I think I might just skip that now...
94% after 1d 13h 49m
Phone idle - 95%
Display - 5%
So I'm going to drain the battery then do a full charge and leave it playing music till it dies and see how long I can get of continues music!
Also the phone signal bar in the battery stats is a full yellow bar... What does that mean?
The others are small little blue bars next to Awake and Screen on...
That's pretty good.
I'd wager that the longer the display is off, the better battery life you're gonna get.
I have personally seen ho the huge display on my Streak 5 drains the battery without doing anyting even marginally intensive.

I am also looking for the same, i also need camera, so my device ll be an mp3 player + camera
could please upload the rom you customized?
As I said, I'm a noob when it comes to not the Galaxy Note but also the Android Operating system. Before switching to Android in April, I was stuck on iOS (iPhone 4) for more than 2 years; before that was the good old Symbian OS on a Nokia N95 8 GB. So far, since making the switch, the experience has been great. Themes, ringtones, tons of customization are just some of the things that are easily possible with "jailbreaking" on my former device.
That being said, I'm still adjusting to my new phone even after 3 months. Thats why I'm starting this thread; I need help on a few questions. So, here it goes (I did search for a lot of these, but no solid solutions) -
1. One of the great things about my old phone was the battery life. Even after using the phone's music function, checking facebook/emails/news/weather every now and then, I would still have around 60%~80% juice left after an 8~10 hour shift at work. None of that on the Note. Just having the 4G running leaves me with around 40%~50% juice after work, with no hard usage like going on the web, or using my phone as a music player. How come? I understand that most of the juice is used by the big-ass display; but there is a still a huge consumption even when the display is not turned on at all. I recently came across a term called deep sleep on the forum; I'm not sure if my phone goes to that or not. How do I check (keep in mind that I'm a noob; I installed CPU Spy, Battery Spy and BetterBatteryStats, but what am I looking for. I'll include a pic from all these apps)? Basically, how do I increase battery life?
2. Charging/Data cables - I dont understand this.. I have included a picture of 3 cables. The 1st one of my brother's from an old HTC phone. This is the only cable I can use to transfer date to and from my phone; that too with a lot care because if I move my phone around, the connection gets lost and I cant even charge my phone unless I unplug the cable, put my phone in a stationary position and replug the cable. The 2nd one is the cable I use to charge my phone. I cant use it to transfer data (I guess because of the little head converter); again, with this cable I cant move my phone around. I have to keep the phone screen-up for it to charge; cant pick it up or move it around or no charge. The 3rd cable is useless. It came with a pair of bluetooth head set. I cant transfer data, nor charge my phone. On some cables, my phone shows its charging; but it either charges very very slow, or shows its at a 100%, but as soon as I take the cable out, the % goes down to 60~85. The phone seems to charge fine on a car charger I have (not a USB car charger, this one has no removable parts). I think it might be the USB port on my phone, but not sure.
3. The 4th picture is of the Go Task Manager widget. Currently its showing 239 MB of RAM free. I closed Battery Spy, and it came down to around 300~325 MB free. Does Go Launcher take a lot of memory? How can I free more RAM? Didnt the Galaxy Note have 1 GB of RAM; what happened to the remaining 305 MB of RAM?
4. ROM - FLOODED = the only word I can use after I saw the Android Development section. So many choices. Is it worth flashing my phone with one of these? Which one do you recommend? Is the one for CyanogenMod good? What exactly does Nightly Built mean?
5. Flashing the phone with a custom ROM voids the warranty, right? Does the "flashing counter" thing work (I read somewhere that there's an easy way of flashing the counter in Recovery to 0)? I included a pic of a crack thats on my screen (long story short, I dropped my phone screen down on a rock). I'm about to send it to AT&T (since I have insurance from them) for the screen (hopefully they'll send me a new one, which will fix the whole charging/data transfer problem too). Will they check the counter too? Should I flash the counter? I have to pay $200 for a claim, be it water damage, accidental damage, theft, loss, etc; if they do check the counter, should the just drop the **** out of the phone so it dosnt work at all?
Long read, I know. Just wanted to cram in as much information as possible so that I can get answers as soon as possible. Any and all answers will be appreciated. Thanks a lot for taking the time to read through the whole thread and replying (if you do).
Ways to increase battery life:
- I hear using wifi as much as possible instead of data is a huge improvement as well as turning off auto sync and you can turn wifi off when the display is off. Also the typical of having it on a low brightness, finding out if you have any rogue apps that are causing more drain than they should. The last resort is to get either multiple batteries or an extended one with a different back case. Aside from those things, you are only going to get so much on time display from the note. I get on average 3.5 hours and can push my phone to about 22 hours from 100%. Milestone 6 Rom, KingKangKernel 5
About the cables:
- Buy a new usb cable. If you ever intend on modifying your phone or even transferring any time of data, you are going to NEED to have a secure and trustworthy connection. And by a new wall adapter. (most phone cables come with the little adapter head for outlets so just make sure it comes included). Pop it off for computer use, and pop it on for wall use. There are a ton of threads about those in the accessories section so you may want to give that a peek. They also have info there about possible substitution batteries.
Ram:
-I don't understand this too much because haha I suck with some techy stuff. But I believe that touchwiz uses a lot of the ram (could be completely wrong) But, I know that a lot of those apps that you are never going to use AT&T(insert name here) apparently constantly are using power and resources. I used to try to clear the ram all the time and it never really went down. Haha sorry I can't help more with this part.
Roms:
- Milestone 6 with KingKangKernel5 ALL THE WAY!!! I would be willing to walk you through the process step-by-step with all the files and such that you would need if you'd like. Other than that, you need to have an idea of what you want before going to the development side of things. Do you want Touchwiz, OC, UV, BLN (YOU WANT BLN lmao), miui, cm9, cm10 (haha), aokp, aosp, aocp, a stock feel, customization out the ying yang. Decide all this stuff and then your choices will narrow drastically to about two or three. From there, it is easy to experiment and possibly decide you had your requirements all wrong and start the process from the beginning haha.
Warranty:
- Get your next insurance claim through BB (best buy). Their black tie protection covers anything as many times as you want without that 200 dollar fee (might as well get a new phone at that ridiculous price!!!) for only ten dollars a month. : D
-Don't know how AT&T does their insurance stuff but I feel if your issues are physical (scratch/ port) that they have no reason to deny you a claim even if there is proof of modification because rooting doesn't crack your screen or break your port. Hahaha, but they can be uptight so I would suggest possibly getting the claim first and then delving into the developmental side of things. There is an odin flashable zip to bring your counter back to 0. I have never tried it personally but many people have had a ton of success with it so I would suggest checking out that thread and just reading carefully what other people do so that you do not make a mistake with anything.
Hope this helps. Hahahahaha, sorry it's so long.
Custom roms improve batt life greatly because on a stock phone u have tons of apps running in the background if u root and flash a rom u can freeze all of them that u want plus now we can over clock our kernels to make r note fly as far as the rom for u ....well u just have to try them diff strokes for diff folks lol i use cm9 roms alot u got to remember ur note has a huge screen so its gonna pull more batt...i also use jucie defender ultimite ...bigjoe has a super everything thread for this phone u can find all ur answers there

1. Battery life varies strongly with usage, in CPUSpy each bar represents how much time the phone processor has spent at each speed. The more time spent at lower speeds the better for your battery life.
If you scroll to the bottom of the list the lowest speed should either be: 384 MHz or Deep Sleep
The phone only enters Deep Sleep if the phone screen is off, and no apps are calling for CPU time. This speed saves the most battery. Rogue apps could be preventing your phone from sleeping. BetterBatteryStats is a tool to help you discover these apps and either: change your usage patterns or uninstall them.
Check CPUSpy first. If Deep Sleep is not at the bottom, or its bar is relatively small then check BetterBatteryStats for the rogue app.
However even if it's in Deep Sleep if you get around the city a lot during the day the phone will be switching radio towers often, switching uses quite a bit of battery. If you stay in a single place for a while you should be able to leave it on a desk for 8 hours and find that you have lost none or almost no battery at all (Such as at night when you are sleeping).
This is a "4G" phone, carrier coverage is spotty and if you are in an area with bad reception or poor coverage, your phone's radio must switch to a higher power level to maintain a connection with the cell tower thus using more battery. 4G towers are more sparse, and therefore 4G has worse coverage compared to your previous phones.
2. You should be using the cable included with your phone. Charging cables obviously will not carry data. But data cables will do both, get yourself a good cable.
3. Don't worry about ram at all. Android has one of the finest ram management systems out there. The phone has 1 GB of ram, 200-300 MB is reserved for the kernel and kernel processes. Therefore you actually have around 700MB, the phone uses the remaining space to caches apps and other required data so that your experience is more fluid and "Lag-free". Not to mention the ram background services and apps are using. Which brings me back to my original point. Don't worry about it, fiddling with it could ruin your experience with the device and use more battery. Don't use apps to clear it, Google has already stated that this doesn't do much.
4. The original rom is your best bet if you want all of the features of the phone. Cyanogenmod is your second choice, Cyanogenmod does not have S-pen support and some of the services provided from Samsung. Cyanogenmod is very lightweight and is the most popular choice among all android devices.
Nightly-Built means that the rom is basically updated every night, so that you can receive the latest features and improvements. You can check every day and there will be a new update for your phone with the latest additions and fixes. However not all nightly builds are stable, but they are reliable at the moment.
5. The counter only counts when you use ODIN to flash bootloaders and kernels I believe. When most of us say "flashing" we mean flashing through ClockWorkMod or CWM for short. CWM does not advance the counter I believe. There are no reports of anyone being denied warranty because of the counter. Do not flash the counter reset, this does count as a "flash" and it is still detectable by AT&T.

1. One of the great things about my old phone was the battery life. Even after using the phone's music function, checking facebook/emails/news/weather every now and then, I would still have around 60%~80% juice left after an 8~10 hour shift at work. None of that on the Note. Just having the 4G running leaves me with around 40%~50% juice after work, with no hard usage like going on the web, or using my phone as a music player. How come? I understand that most of the juice is used by the big-ass display; but there is a still a huge consumption even when the display is not turned on at all. I recently came across a term called deep sleep on the forum; I'm not sure if my phone goes to that or not. How do I check (keep in mind that I'm a noob; I installed CPU Spy, Battery Spy and BetterBatteryStats, but what am I looking for. I'll include a pic from all these apps)? Basically, how do I increase battery life?
To increase battery life you can do a few things. Obviously, use as low brightness as you can stand using, and also try to use wallpapers with lots of black, as black pixels do not draw any power on amoled displays. Next, from your CPU spy pic it looks like a rogue may be holding your device in partial wake lock, as your 384 MHz stage has twice the time of your deep sleep stage. Uninstall any apps you dont need, like benchmarks and other one time use apps like that. Also, if you have stuff constantly syncing, that will drain battery with the screen off too. If you need push email, leave sync on, but change the sync settings of less essential apps to manual sync only, so your phone only syncs those when you use the app. Along with the syncing, if you are in an lte area, data usage will eat much more battery than the iphone for the same data usage. Lastly, if you have crappy cell service, that will also contribute to faster drain.
2. Charging/Data cables - I dont understand this.. I have included a picture of 3 cables. The 1st one of my brother's from an old HTC phone. This is the only cable I can use to transfer date to and from my phone; that too with a lot care because if I move my phone around, the connection gets lost and I cant even charge my phone unless I unplug the cable, put my phone in a stationary position and replug the cable. The 2nd one is the cable I use to charge my phone. I cant use it to transfer data (I guess because of the little head converter); again, with this cable I cant move my phone around. I have to keep the phone screen-up for it to charge; cant pick it up or move it around or no charge. The 3rd cable is useless. It came with a pair of bluetooth head set. I cant transfer data, nor charge my phone. On some cables, my phone shows its charging; but it either charges very very slow, or shows its at a 100%, but as soon as I take the cable out, the % goes down to 60~85. The phone seems to charge fine on a car charger I have (not a USB car charger, this one has no removable parts). I think it might be the USB port on my phone, but not sure.
Buy the stock Samsung wall charger/cable. It will do wonders for you. Solid connection, full speed charging, and data transfer.
3. The 4th picture is of the Go Task Manager widget. Currently its showing 239 MB of RAM free. I closed Battery Spy, and it came down to around 300~325 MB free. Does Go Launcher take a lot of memory? How can I free more RAM? Didnt the Galaxy Note have 1 GB of RAM; what happened to the remaining 305 MB of RAM?
Don't worry about ram usage, android as an os manages it just fine by itself. No need to constantly kill apps or use task killers other than the stock one if you absolutely need to kill something. Constantly killing apps/clearing ram can actually decrease your battery life as well, as constantly killing and restarting apps uses far more resources than leaving them running. Also, if you're constantly killing apps that have push syncing or interval syncing, they will just restart anyways, essentially just killing battery every time you clear ram. Lastly, use as few Widgets as possible. They are nice and pretty, but unless you need them they're just another service that is running, and will slow down your launcher performance if you have too many.
4. ROM - FLOODED = the only word I can use after I saw the Android Development section. So many choices. Is it worth flashing my phone with one of these? Which one do you recommend? Is the one for CyanogenMod good? What exactly does Nightly Built mean?
Remember, there's no rush, and no "best rom", so just take your time reading how to flash each rom, and try each one out that looks appealing to you. Nobody can tell you what will suit you best, and since all of the roms are great around here, you really can't go wrong trying any of them until you find what fits you best. Custom roms are totally worth it, as they have all of the fat trimmed and are really fun to play with. Be careful though, you may find yourself developing an addiction after you get the hang of things. =].
5. Flashing the phone with a custom ROM voids the warranty, right? Does the "flashing counter" thing work (I read somewhere that there's an easy way of flashing the counter in Recovery to 0)? I included a pic of a crack thats on my screen (long story short, I dropped my phone screen down on a rock). I'm about to send it to AT&T (since I have insurance from them) for the screen (hopefully they'll send me a new one, which will fix the whole charging/data transfer problem too). Will they check the counter too? Should I flash the counter? I have to pay $200 for a claim, be it water damage, accidental damage, theft, loss, etc; if they do check the counter, should the just drop the **** out of the phone so it dosnt work at all?
Yes, flashing roms does void your warranty but only temporarily. You can set it back to stock firmware again and be just fine returning or replacing it. People have also returned their phones with the counter tripped, as it seems that as of right now, neither att or Samsung cares about it. Have you flashed anything yet? If not, get your phone replaced before you do just to be sure, then when you get your new one back, you can have already read and downloaded everything you need to root and rom it as soon as you get it back. =].
Long read, I know. Just wanted to cram in as much information as possible so that I can get answers as soon as possible. Any and all answers will be appreciated. Thanks a lot for taking the time to read through the whole thread and replying (if you do).

Ok first keep in mind I came to android with almost the same background as you and about the same time.
Question 3: anything with Go in the name I have seen huge team usage... also custom Roms will be a great thing for your ram you will see big changes if you go with anything like AOKP AOSP or AOCP. These are as close to basic unmodified android as you will find with little to no extras.
4: cyanogen mods are good in my opinion, nightly builds are not finals they are updated nightly... as for a Rom I tried a few and have found my favorite is the collective builds.they just came out with the AOCP (newly updated coming soon) and there is one member of the team that likes ultra slim builds and he slims them down to the bear bones. When ready to flash give them a shot.
5: flashing will void warranty, with that said so did the crack you have. This counts as physical damage. So insurance is the best option. I do agree best buy ins is great but as you have att ins might as well use it. With a crack screen I think you will get a different device to fix charge port but will most likely get refurb phone. I would root and flash with this one so you can do it and IF anything goes wrong you need an instant replacement any way and your not out anything
Other 2 questions I didn't feel I was the one to answer nor am I a expert on any of this, just the info I have
Sent from my AoCP Note
Battery life isn't the greatest on the Note, but it's acceptable. If you use it a lot, the battery will drain. You can try using a different CPU governor (lulzactive, smartassv2, etc. in custom kernels) to improve battery life or just use powersave (which decreases performance but improves battery life). You also have to account for the huge screen which is OLED, not LCD. With an LCD (like the iPhone 4 has) there is an array of white LED's that illuminate the screen. There's probably 8 or so of them. The LCD glass is a color filter which colors the white light from the backlight. The LCD itself uses little power, and the LED backlight only has 8 or so LED's. The Note uses an AMOLED screen (Active-Matrix Organic LED) in which each individual pixel is four independent LED's (RGBG). They're small LED's and use little power on their own, but you have 1280x800x4 of them (well, not quite due to the pentile arrangement staggering pixels). When they're all on (white screens) it uses a lot of power, especially when brightness is up. On the plus side, when they're all off (dark screens) they use much less power. To save power on an AMOLED, use a darker background/theme.
As for RAM usage, the Note has 1GB and you really don't need to worry about checking it. Android manages RAM very well, especially when it has 1GB to work with. When you leave an app in Android it isn't closed, merely pushed back in an application stack. Only when Android determines that RAM is filling up does it start removing stale apps from this stack.
Personally I've used my Note with many different cables without issue. The included Samsung charger and cable work very well, and I think has the most solid connection of all of them, but I've had success with a cord from my Archos media player as well as my HP TouchPad tablet. The TouchPad's wall charger also gives a slight charging boost as it provides more power (2A vs. 1A) but the Note's highest charge rate is around 1.1A so you don't see a huge difference. It does need a bit more than a standard 500mA USB port provides, so if you plan to charge it off your PC or a 500mA charger, you need to turn off the screen and leave it off, otherwise the screen will eat up the power, leaving none for the battery.
My favorite ROM is CyanogenMod 9. This is a built-from-scratch (Google's source + modifications) ROM that includes a lot of nice features while retaining the stock Android look and feel. I personally do not like TouchWiz or the customizations that Samsung added to their Note ROMs but many people do. It's all about personal preference. A nightly build means that a new release of the ROM is posted (usually by an automated system) every night. This is what CyanogenMod uses for most devices, as their project has many developers and is constantly updating. You don't need to update every day, but a nightly ROM means that you always have access to the latest updates if you want them.
As for the flash counter, I would warranty the phone before flashing a custom ROM. I generally don't take warranty into account on my tech purchases because with all the hacking I do it's often void, but usually if you restore the stock firmware they will fix hardware issues obviously not caused by your ROM flashing..
Thank you all for the quick replies.
Regarding the cable, I've come across this on amazon - /gp/product/B007JZGO6S/ref=ox_sc_act_title_1?ie=UTF8&smid=AR2TEZS0WRV7S
Good to buy?
@Ph0n3D0rk - Thank you. Due to the short battery life I've been experiencing, I always use my phone on brightness all the way down with "Automatic Brightness" option turned off. I only have 200 MB per month data, so wifi's the only way to go . I've been looking into extra (or extended batteries); maybe soon. I read into Milestone 6; seems pretty interesting. I might give it a go (maybe when I get the replacement). I'll private message you about it.
@JB calhoun - Thank you. I've started looking into different kinds of ROMs. Is it possible to try out 2 different types or ROMs at the same time? What I mean is that say if I install CM9, then I want to try Milestone 6; will I have to remove CM9 to try Milestone 6? Also, does installing a new ROM every time (almost all instructions say to do a "Wipe data/factory reset") means all my data (on the phone ofcourse and not on the SD card) will be lost? I'm mainly worried about my text messages and whatsapp conversations (I think all other data settings are saved by Google, and reapplied once the app is installed back again, right?)
@SkyStars - Thank you. I tried using BetterBatteryStats, but I have no idea what I'm looking for. Should I be looking at Processes, Partial Wakelocks, Other or Kernel Wakelocks; and then what in these? I've heard a lot about CyagnogenMod. When you say it does not support S-pen, does it mean that the phone has no use for it at all? Can we still maneuver the screen with it, or take screenshots? Or does it just stop working? So, I should stay away from flashing the counter? My counter (I think) right now says 4.
@welchertc - Thank you. I found out about keeping a black wallpaper to decrease battery use a few weeks ago; I've had a black wallpaper since. I'll remove useless apps, then lets see what happens. Is the link I provided in the beginning ok, or should I search for something else? I was wondering about killed apps popping up after some time (Facebook for example). I have email sync turned off. I've been trying to turn off sync for a few apps, but some of them dont give me such an option (eg. The Drudge Report). I have started looking for some ROMs. But I ask you the same question I asked JB about ROMs - Can I have only 1 ROM at a time? And, will have to erase everything every single time? The warranty problem's the same with Apple. Just like you said, it seems to be the same with Apple - just reinstall the stock iOS, and you're ready to go (I had my iPhone changed after I went back to stock from a jailbroken firmware after it also developed battery issues; the new phone I received was brilliant in the battery department). I think my counter is up to 4.
@spade1031 - Thank you. Milestone 6 is an AOKP release. I'll look into the other releases you've mentioned as well. I've been using the Go Launcher because I tried AWD, and didnt like it. Any other nice ones out there? (But maybe I wont need them after a ROM install).
@CalcProgrammer1 - Thank you for the very informative and in-depth writing. What exactly is a CPU governor? If it is what I think it is, then I think I used one back when AT&T hadnt rolled out ICS, and I had (somehow) rooted the older version. I installed an app (dont remember the name) that basically let me create profiles in which I could set the max and min CPU usages; is that it? So I shouldnt worry about closing apps using any witget? The reason I ask is because the phone tends to get a bit slugish when a lot of apps are open, and available RAM (as shown on Go Taskmanger is around ~75 MB). I'll try not closing any apps from now on and note the difference. If I do go with CyanogenMod, what exactly will I be losing in terms of TouchWiz? I have flashed before (tried ICS before it officially came out), so my flash now is at 4. Should I take a chance and turn it in as is and see if they still change it; or should I try flashing the counter before turning it in?
Once again, thanks everyone for the replies.

Go Launcher is alright (for now) because of all the widgets they make.. They turn out pretty crappy when used with other launchers..
Just tried Nova Launcher. Seemed good, but I think I've gotten used to Go Launcher.. But I will definitely make a switch soon..
Also, one of the very first replies to the thread you posted about suggests overclocking. Will I be able to do that when installing custom ROMs?
Regarding how to read Better Battery Stats, the developer of the app is very active on xda and you can actually get help reading the logs from the app on the app thread on xda.

To turn off all auto syncing, like I do, Just go into accounts and sync under settings and there should be one box or slier to uncheck to turn off all auto syncing. You can also leave it on and configure your individual accounts such as email, twitter, and facebook to sync automatically or not. =]
And yes, you can only truly run one ROM at a time. You could make a nandroid of one ROM, flash another and configure it, then nandroid the second once you have it set up, then keep restoring those two nandroids every time you want to switch. Although that is pretty ineffective if you like to keep switching things up on your homescreens, as the nandroids stay exactly the same.
You also don't need to erase everything per se. All of your pictures and stuff are a good idea to backup, to your computer or an sd card, if you're flashing a rom that requires a full wipe. Your apps and app data will be wiped, so definitely buy titanium backup pro if you haven't already, as that will allow you to restore all of your apps between flashes. Also, there are various sms backup apps, though I've never used one so I can't recommend any. email you can obviously resync quite easily, same with contacts once you have them all synced to your gmail account. Other than that, about the only thing you can't restore afaik is exactly how you have your homscreens/wallpaper setup.

There is really only like 3-4 unique roms in there. The majority of them are peoples themed versions one of those.

To be honest I tried overclocking only once am I was on a super light weight Rom, with that I didn't see much improvement but I have noticed the people do see am improvement are also using bigger Rom s. Again I'm sure you will see this many times more you are on here "flash it and find out" the reason is no one has done every combo out there. But over clicking will help at times just keep in mind your not happy with the battery now? And your gonna run your phone harder? Lol

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?

Can you please point me in the "settings" direction? I think I'm doing all things right, going real low on app usage, sync-ing of apps, screen settings, etc.
What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

As far as the battery issue is concerned,do a clean ROM install through Odin.

Hi,
Recently, compagny for the one i work bought around 100 Galaxy S3 for the technician on the road and for everyone else. Most of us found that the battery doesnt last the full day. Around 3-4 hours and we all work mostly 8-10 hours per day.
We installed Airwatch to prevent users of installing apps in the phone butwe still have problem with the battery... Phone cant be root / custom roms.
Is there another way to removed nearly all applications that we dont want and that can drain battery. We only need like bluettoth, phone email and calendar. All the rest can be removed to save battery.
Thanks a lot

No not without root... Most system apps are bloatware and can be removed to improve performance and battery life but like i said you need root to do this.
You can do things to save battery life like turn screen display down turn off gps etc also you can also download apps from play store to help save battery (but these are not as effective as uninstalling system apps) and since you have barred the download of apps this obviously is not possible.
thanks a lot for the answer
Do u mean 3-4 screen on time or standby time?
