ICS SOD with Green Power - Galaxy Note GT-N7000 General

Just want to confirm a hunch that power savers (like green power) trying to control wifi may be one of the causes of screen of death (SOD).

SODs are caused by incorrect Kernel/Modem combinations.
I finally got rid of all my SOD problems when I found a modem that works good!
Really

Any juice saver would be absolutely the last thing I'd want on my phone. That's treating cancer with carcinoma.

Why is that? Green Power works great here on Stunner's 1.4.19. Turns off wifi and data a minute after screen is off and there's no significant data usage and turns it on every half hour to sync with all my push accounts. When I turn the phone on all data connections are restored and ready to use when I've unlocked it.
Does it work? Hell yeah! I only lose 3% max each night as opposed to 8% to 12% without Green Power. I still get my Whatsapp/Gmail/Wordfeud/etc. messages when it's turned off, albeit sometimes a little late which in my case doesn't matter at all. If it's important, either call or send an SMS text message, you can't expect someone to always be in an internet covered area.
Now task killers is another story. Android has a great memory management and most killers will eventually cause more pain than neccessairy.

Anything that attempts to underclock has a high risk of crashing Samsung ICS kernels that haven't had source fixes applied.

Great to hear from the SOD hunter!
GreenPower doesn't underclock like JuiceDefender. However, after lots of SOD's I noticed in the battery chart from settings that prior to SOD, WIFI was stuck ON when device was not awake, when GreenPower should turn it off whenever screen is off. I tested with uninstalling it and tried an alternative (Battery Defender) and no SOD's for 3 days. I had them a couple of times a day since LP1.

[Q] Battery life makes me cry

(I'll preface this by saying that I am well aware there have been a million threads about this, I'm sure, and I'm even more sure that there will be a million more. And I have searched, and searched, and searched some more, and I still feel the need to post this question. Flame me if you want. I'll use the flames to heat up some tea, or something.)
I bought my phone last Thursday, it got lit with service Friday. I went over the weekend and into Sunday with stock ROM/kernel, and decided to mix things up by rooting my phone and using the MixUp kernel to see if I could get better battery life.. and it didn't work too well. I mean, life went up a bit, but not noticeably so (maybe twenty or thirty minutes?)
After that, I flashed Syndicate, which had Xtreme Kernel. I calibrated the battery as instructed inside of Clockwork and went with it for Tuesday.. took it off the charger at 8:00 and it died around 4:00. Kept the same kernel and flashed Epic Experience and the attached JuicePlotter shot is where I am at right now.
My usage today has been light browsing and that's basically it. I've got the processor underclocked to 600 with SetCPU, and JuiceDefender and Superpower have been preventing any data from going on when my screen is off, and for the last two hours I've been listening to MP3s using the in-built music player.
This makes me cry considering there are people on here saying they're able to get much more life out of their battery, even with BT and WiFi etc. I'm aware that each phone is different and all that, but still.
All that said, is there a problem with my phone/battery, is this par for the course with the Epic, or should I just stop whining?
Thanks in advance for any help/insight.
A couple of things...get a task killer app so that you can kill the drm process which eats up a ton of battery, calibraing your battery takes 2 or 3 times going from full charge to zero and also, since its a new phone it takes charging to full and letting it get down to complete zero a few times before you will see better battery life no matter what else you do
Edit: oh and also definitely do the airplane mode toggle as well

Also, for each new Kernel you flash, you have to calibrate the battery.
Charge it to full, boot off, boot up in Clockwork, go to Advanced and Clear Battery stats. Reboot the phone, use it until it runs dead and shuts off, than plug it back in and charge it to full with the phone on.
Every time you flash a new kernel, you have to do that process so the battery calibrates to that certain kernel.
Also, try Baked Snack, it gets the best battery life for 2.1 ROMs.
http://www.bakedsnackshack.com/source/
Download Bakedsnack1.6 and Step 2.
Make a backup.
Wipe data/cache
Install 1.6
Boot the phone up
Reboot into clockwork
Install Step 2
Boot the phone up.
I have to have a car charger if I go anywhere. This phone dies so fast with normal usage. Do anything crazy like turn features on, surf the web, or increase brightness, and I am lucky to get 2 hours. I have multiple batteries, both have the same result.

2 Hours..? Whaaaaa? Lol.
When I calibrate my battery, I turn EVERYTHING on, screen brightness all the way up, Pandora running, every widget I can fit on my screens set to update at their quickest setting, screen set to 30min (Though I never let it shut off). Bluetooth, GPS, 4G running (I don't have 4G here, so it just keeps searching, which drains it more than if it was connected). And running the Maps Live wall paper to use GPS.
When I do all that, I can't get it to even die under 4 hours.
Hopefully you were exaggerating with saying 2 hours lol.
Thank you guys for replying!
Sh0wNuF: I killed the DRM service today and used ATK to kill errant processes throughout the day today to no avail. I also used the airplane mode toggle to try to limit my time without a signal.
SemiGamer: Thank you! I did do the clockwork step as I said in my first post, but I will try to install BakedSnack and get back to you guys as to the battery life.
From the looks of that juiceplotter graph, your data is constantly on and destroying your battery. What is the point of having juicedefender if the data is constantly on?
If you set up the phone properly, and there are a MILLION threads on this which state a MILLION times to disable DRM and toggle airplane mode as a mere baseline beginning, you should lose at most 1% an hour when the phone is idle without a data connection and the screen off.
Now it looks like you probably have the data on constantly with emails rolling in, facebook auto updating every 5 minutes, weather checking every half hour and other things that are just destroying your battery life. If you need your phone to do all that nonsense, then you will be crying for the rest of the time you have it.

Thank you for your reply, but as I said in my first post, I was using both JuiceDefender and Superpower to make sure data was off in the background, and as I said in my most recent post, I did disable the OmaDrm service as well as enable/disable Airplane Mode to lower my TWS.

Thats fine, but your data aint off. Look at that graph you posted. Every little blip is either data being accessed or the screen turning on. The line should be smooth if there is no data and no screen on.
So there are two options, either you are constantly using the phone and its the screen killing the battery, or you have juicedefender set up all wrong and its the data killing the battery.
If I remember correctly, any spike below the line is data, either wifi or 3g and any spike above the line is the screen turned on. So from the looks of it your data is literally never turning off and you are checking the phone and turning the screen on and off pretty frequently.
What are your settings in juicedefender?

I have almost identical batter results as you. I do use the phone fairly often to send messages but the screen brightness is all the way down and I use set cpu on the froyo beta leak. I reset battery stats and also (perhaps you could look into this too) checked spare parts for any rogue programs. Does yours say the screen takes up most of your battery even if you barely use it?

I would up the Schedule to less often and turn off the traffic toggle. Also, I wouldn't doubt that your phone is never going to sleep. If you have spare parts check the Battery History. If you listen to music with the phone, the service started by the music player, CorePlayerService, keeps the phone awake constantly for me. I ended up making a simple kill music widget using tasker to fix this issue.
I bought a wildly overpriced Samsung stand/battery charger from Amazon. My wife & I each start the day with a charged Epic and a spare battery. No worries

When you say much better battery life exactly how much? My battery dropped 20% today while not being used and Display was still at 60% (I turned the alarm off twice). I'm running the Quantum ROM which could have something to do with it but the battery is horrible for me. I can't get more than 8 hours and that's if i barely use it. I have spare parts and no apps are partially waking it. Just Wifi and sync. No GPS, brightness all the way down. The main thing that bothers me is that display is always #1 even if i don't use the phone at all. Any thoughts?
I've ran both Quantum and Viper Froyo roms and aside from making my phone hot enough to fry eggs, the battery life was not good.
As far as battery life goes, I'll start with the obvious stuff.
1. Turn off GPS, Bluetooth and 4G. 4G is a complete power whore.
2. As for wifi, turn it off unless you are in a bad coverage area for cell data. If you are connect to wifi and set Spare Parts to never let wifi sleep.
3. For DRM there are 3 files you need to remove that will prevent it from running / reinstalling and they are DrmProvider.apk, DrmUA.apk, and SisoDrmProvider.apk.
4. Toggle airplane mode every single time you reboot without fail.
For a true test of whether your phone simply needs to be returned as "defective" you should wipe the device, dont setup a google account and let it run for a day after executing steps 1-4 above. It would be best to an apk for Spare Parts and SDX Stock App Remover on your microSD that could be installed using My Files. If you still have problems take the phone back to sprint (after restoring it to factory of course) and tell them it is defective.

Here's a JuicePlotter graph from today for comparison from my original one yesterday.
I still wonder if it wasn't going to sleep because of PowerAMP and I didn't underclock today like I did yesterday.
There are a few other physical issues with my phone (slider seems a bit loose compared to my other phones: if I swipe with slider closed with a bit more pressure than usual, I can feel the screen move up and down; screen seems to slightly come up a bit when phone's tilted a bit, taps make you feel the screen go back down) that also made me want to consider exchanging it on top of the battery issue but if I'm getting good battery life I don't think I'll mess with what works, unless anything gets worse.

I solved my battery drain problem

I was having a problem with fast battery drain on my SGS2. I would get 15 hours if lucky from a full charge with light - moderate use. My most recent charge looks like it has doubled the time.
What did I change? I did a factory reset and manually installed all my apps, NOT using titanium backup. I had used titanium backup to restore apps only, that were from my previous phone (Nexus1). I have never used titanium backup for system settings, only apps, but it seems even that is unreliable. I've now stopped using titanium backup completely.

Will it matter if it's i9100 to i9100, or just any other phone to i9100?
Well... Ive done several hard resets , because I though I had a network problem , and I many of those I didnt install titanium or even root the device and the battery life was the same.
Just one opinion..

If you notice a higher battery drainage than normal then you have to see what application you've installed lately. If you can't find it then the only option is to do a Hard Reset. That has worked for me, IF your battery is drained by some app which you've installed lately.
Regards.
I am sure battery drain has to do with the apps we installed and the settings we use.
We are in a fortunate situation that my wife and I have both S II, hers is 2 days older from the same shop, so I assume both devices are from the same batch. Hence no hardware difference.
I installed a lot app and played with lots of settings and if my wife like it, she "demand" to install it on hers too, so hers is a more controlled env.
For some reason my battery drains a lot quicker than hers. I still have to find out which application / settings cause this.
For an experiment, we did not use both phones for a full day (very difficult), so all the drain is due to background processes.
There are several dips in the graph, but those are explicitly usage of the phone for a while. The big last drop on her battery was because she was playing a game for more than 3 hrs.
PS.
A collegue of mine (also an SII) had his battery run out quickly, until he found out his culprit: Settings->Location and security->Use wireless network was ON.
You can see the effect of this as the "almost horizontal bar" in my wife's battery when we turned it off.
thx for info man.
What would happen if i turn that off? I want to try this to preserve my batt life. Thanks!

PB_2003. You had to use one phone to make a shot of another phone? Just hold down the home key and press the power key. You will be able to take shots like the attached.
I have used TV to restore many times and battery life is fine. I'm would suggest that the issue is some app you are restoring rather than TB

I wonder if having 3rd party launchers like launcher pro drains the battery quicker. I installed launcher pro without ever having really tested the battery life of the phone with the standard launcher. Has anyone here tested the difference, if any, of the battery life of standard v market app launchers?

The screen shot on the left is your phone correct? It looks like something is waking your phone up and leaving it in an awake state for far too long. Your graph represents over a day's time and I see those huge chunks of time where your screen is off but your phone is awake; I'd say some program is what do they call it *wakelock* every now and then.

it's not just the apps that was just installed. It should include apps that are updated. I had this issue on SGS I when beautiful widget was having issues with updates causing the phone to use more battery power than usual
Morel likely to be a bad app, or a bad app setting causing the app not to close properly then drain power than the mere fact you restored it via titanium.
anyone one trying while sleeping, off your packet data ?
for me i tested,
2350 @100% to 0700 @ 99% (during packet data off)
If on, it will left 70% ++ in the next morning..
why is that so?
This is my battery drain using Litening ROM 1.5
I usually make and receive 30min phone call a day, push email on 2 accounts, wi-fi at work, data always on.

Turning off data packet doesn't allow any application going on line (unless you have your wifi on) and cannot download e-mails, synchronize anything, etc..
This saves your battery a lot.

Yes, that is also what I suspect. It is just to find out what which application / settings this cause.
I found out that I have 4 apps has an "sync" account, I delete all of them (except gmail), now I got a lot better performance (1 day: still 75%).

Of course the updates are included. There should be an app/good optimized app which will allow us to close the apps and thus Auto Sync and Background Data to off when we are not using them, especially at bed time. The in built task manager's RAM Clearance function is crap and frankly I haven't found an app which will optimize the RAM without force losing the apps/widgets. Tried 'Gemini App' but I doubt! This 'Sync' stuff is the main responsible part of high battery drain.

Improve your Xoom's battery drain/standby substantially!

This app has made my battery last 4-5 days instead of 2. It is called Auto Airplane Mode by DON. It does just that, automatically enables airplane mode when the screen turns off. Most battery drain occurs while in "standby." This app shuts all connections off and saves a big chunk of battery.
I am sure it will work for your phone too, but since you receive calls on a phone it would kinda defeat the purpose.
Here is a link to the android market.

In theory this is a helpful app for those who aren't looking to sync devices during these intervals of having the screen off.
But I think in the case of the WiFi only Xoom this isnt necessary because WiFi turns off during screen off anyway right?
And on 3G it may prove to be more helpful because of sync. But the number one killer of battery on a tablet should be the display.
Anyway, good call for the app. Thanks for sharing with the community.
I dunno I don't experience that much battery drain, I been getting around 4 days with causal use (wifi model)
...and why would you want to be in air plane mode when the screen turns off on your phone?? You wont be able to receive phone calls or messages. mind as well turn off the phone at that point lol
But at least we have no Amoled-display. Amoled is the most consuming type of display.

No, you have a choice and HC3.2 has a bug that can cause random reboots unless wifi sleep policy is set to never. Don't know how this would affect that issue.
In moray rom it is one touch on/off(notification area)
so,while watching movies or listening songs one can turn off the wi-fi.

I worded that wrong. Obviously, your battery will drain more WHEN YOU ARE USING IT and the screen is on.
For many people, myself included, the "standby" battery loss/drain is excessive. This app helps A TON with that.
Mike the majority of understand you what you mean.
Some tablets spend most of their time and energy "waiting" to be used.

I can't complain too much about my battery life. My Wifi is always on 24/7 even when the screen is off or I am not using it. I like to be notified at all times, ya know. My CPU speed is way underclocked with the screen off so I get a killer standby time regardless. I don't even notice any kind of battery drain at all really with my Wifi always on, but a good tip nonetheless.
Underclocking is an amazing way to save battery life when you are not using it, or even when you are using it. For root users only, of course. If one were to be rooted that is what I would reccommend the most for someone looking to save battery life. Underclocking+undervolting makes for a power saving beast. Even more so than just disabling all connections.
But, combine auto airplane mode/Wifi screen off and underclocking+undervolting, and you have the ultimate power saver. If you don't need to get emails or notifications of any type this would be perfect for you considering the fact that all connections would be disabled.

Ridiculous ICS Battery Life

On Friday 1 June 2012, which is Friday last week at the time of writing, I gladly updated my phone through Kies after receiving word of the UK update being available from these very forums. Over the past week, I have noticed that my battery life is considerably worse since my upgrade to the new Android version and, when hearing of people hear who manage up to 36 hours of battery life through this phone, I really want to find out what they are doing exactly. At present, I have set the brightness at 1% (the minimum) and only up it to 40% when out in bright light conditions. At home, I also use the Screen Filter app which dims the screen further (I have this set to 50% of my already 1% brightness setting) and claims to improve battery on AMOLED devices. I also have Juice Defend Ultimate running on "Aggressive" mode along with the built-in power saving mode running as well. Yet, looking on CPU Spy, my phone still does not enter deep sleep which is needed to see a real improvement in battery life as far as I am aware. I have tried restarting the phone and also plugging it back into charge before unplugging it with the screen turned on as many have recommended. Any ideas what else I can do?
Uninstall juicedefender. Its not uncommon that it drains a lot more juice than it saves.
There is must be any Application that is hogging your battery.
Install better battery state... Find that application and uninstall that.
I am getting better battery life in ICS as compared to GB...

I have that app installed, but frankly have no idea how to use it very well. From what I can tell, it is Kik Messenger which is creating a partial wake lock (but I need that to send pictures to my friends), Juice Defender which is supposedly saving battery life and biggest partial wake lock is RILJ or something. But, that is caused from a weak signal and I get that regardless of network at my house. Besides moving, I cannot alter that. As for Juice Defender, I've heard nothing but positive reviews from it. My main aim is to get deep sleep working, but how?
Install Better Battery Stat and check what app is actually causing the problem :

On Friday 1 June 2012, which is Friday last week at the time of writing, I gladly updated my phone through Kies after receiving word of the UK update being available from these very forums. Over the past week, I have noticed that my battery life is considerably worse since my upgrade to the new Android version and, when hearing of people hear who manage up to 36 hours of battery life through this phone, I really want to find out what they are doing exactly. At present, I have set the brightness at 1% (the minimum) and only up it to 40% when out in bright light conditions. At home, I also use the Screen Filter app which dims the screen further (I have this set to 50% of my already 1% brightness setting) and claims to improve battery on AMOLED devices. I also have Juice Defend Ultimate running on "Aggressive" mode along with the built-in power saving mode running as well. Yet, looking on CPU Spy, my phone still does not enter deep sleep which is needed to see a real improvement in battery life as far as I am aware. I have tried restarting the phone and also plugging it back into charge before unplugging it with the screen turned on as many have recommended. Any ideas what else I can do?

first ,samsung ICS is poorly made ,second you have a high chance of bricking if you wipe your phone with their official kernels so don't do it.
third ,like others said ,juice defender (and any app of this sort) doesn't work anymore (android 2.2 and up) so just uninstall it.
fourth ,not entering deep sleep is mostly due to a rouge app ,and since wiping is not an option for you you need to hunt it down manually ,use better battery status (learn how to use it!!!) and uninstall any apps you don't need.
fifth ,get some knowledge then get rid of crappy touchwiz ROM and install CM9 ,you'll see a huge improvement in terms of performance and battery life.

Okay, well this is my first proper Android device (minus an old second-hand HTC Desire which had awful storage and I used for around one month). Secondly, I do know that other ROMs offer better performance and battery life but flashing them onto my phone is something I'm not very comfortable with and surely it would also void my warranty. I've only had the phone for four weeks and don't want it wrecked already.

I'm fairly new to android as well ,had an S2 (which was so good that I only rooted it ,no custom ROMs) for 5 months before the note and that's it.
but I rooted my note the first day I got it ,and installed a custom ROM less than a week later (was a total noob at the time but I read and learnt quickly) .
then CM9 arrived and I flashed that immediately and haven't regretted it so far.
but I had no warranty to begin with so.....
note that if there is something that can wreck your shinny new note ,then it's amsung official ICS update (read the announcement sticky on ICS and bricking) .
but how experts can explain the fact i face:
With every official and custom ROM i install, even CM9, my note keeps eating battery when in use plugged to the charger... it's unbelievable... I can't understand how it happens.
by the way: i always full wipe before installing any custom/official rom.

Well, is there nothing that I can do to trigger deep sleep or improve battery life on the stock ROM first of all? Secondly, how difficult is rooting and would that void any warranty?

it can't happen ,I'd say you either have a faulty battery\charger or there is someting wrong with the phone itself
the note charges while in use and connected to a charger.

yes you can ,uninstall the violating apps ,learn to use better battery status ,you'll find that there is an app or two responsible for the wake locks ,thus preventing the phone from entering deep sleep.
or simply install every app and game that seems suspisious or poorly made ,and just keep the essential ones.
as for rooting ,it couldn't be simpler if done carefully and to the letter :
1.flash back to GB using PC ODIN
2.root it
3.backup your EFS folder (important , very important) search for it on the forums.
4. install custom ROMs (stay away from unsafe kernels please ,read the sticky thread about ICS kernels)
3. enjoy
use this guide
http://forum.xda-developers.com/showthread.php?t=1329360
yes there is an easy way to root while on stock ICS as per to this guide ,but I prefer you stay away from official ICS for the sole reason that it's dangerous.
remeber the key is to read and read and read ,in a month you could become a pro
on the other hand if you go the lazy way ,you could just end up with a bricked phone
also once you root ,your warranty is void ,though if you're careful you can return it to stock condition and they won't tell the difference
be careful

That's just wrong. CM9 battery drain with screen on is far, far worse than Stock ROM.

no my friend ,I'm afraid you're wrong ,with the 4\6 nightly my phone was running with low usage for 48+ hrs .
the battery life is phenomenal for me .
@Brad387
I have had mine for about 2 weeks. When I turned it on and did the initial setup it had a new software update which was ICS. Since then I have been having issues with deep sleep as well. I turned stuff on and off and it has been totally random what was preventing it from going to deep sleep.
I have done this trick that has been on this forum.
Put you phone to airplane mode.
Power it off completely
Remove battery for 20 seconds or more
put battery back in and power this thing back on
then turn off airplane mode.
This seems to have helped me get into deep sleep. BUT there have been instances of rogue crap going on. Like I was using Google maps with GPS on. When I got home and was done with my traffic mapping I turned off the GPS switch and turned off my phone. I checked an hour later and the battery had died 10% since I got home which was more than when I was driving. I checked Better Battery Stats and it showed that GPS was running that whole time. So I turned on GPS again in the toggle waited a couple seconds then turned it off again and bang it went into deep sleep. It sucks that I have to check crap on it all the time and have become a bit paranoid because the GPS glitch had my phone running pretty hot. Since then everything has been running well and deep sleeping.
There are other things I did do too and the below stuff is up to you if you wish to proceed. I rooted my phone which was very easy...at least for me. http://forum.xda-developers.com/showpost.php?p=20963730&postcount=3 this is what I used with no problem.
From there you can freeze a bunch of stuff you may not use like Social Hub, Accuweather etc etc.You will need Titanium for that though and root access.
I logged out of Latitude too which was on by default for some reason.
If I remember anything else I did I will hit you back here.
Bottom line was finally yesterday I was able to get thru the entire day without needing to plug in so there is light at the end of the tunnel...I hope.
Not sure if this has been mentioned but CPU Spy lets you see if you are getting into deep sleep mode and how much time you are in it along with the other CPU mhz that its running.
Hopefully this can help out a bit because I have been in the same boat and it has been driving me mad. Sorry for all the random thoughts too...I just typed them as I remembered things.

My phone does not seem to enter Deep Sleep, but runs constantly at 200 MHz instead. At present, after turning on the built-in power saving mode (not noticing any performance differs so can't even tell what it does), running Juice Defender Ultimate on aggressive and screen filter I burn around 2% per hour if I just leave my phone locked. Is that healthy?

Actually, there is something you can do about that!
Both Vodafone and Three can supply you with a Femtocell which can greatly improved your signal at home, and uses your home broadband as backhaul.
I know, because I have them!

Battery life of my Note was horrible after upgrade to ICS, and actually already quite bad the last month on GB2.3.6 (all unrooted).
It could get quite warm and often when opening my case the screen was already on.
So I did wipe my phone, reinstalled all apps and battery life has improved immensely.
I see several warnings here about chance to brick your phone when wiping on stock ROM, but not solving the battery drain is of course no option and we don't have a guarantee from Samsung for nothing...

Well, thanks for offering that advice but how expensive are these things? Also, I'm the only person on 3 in my house so kind of a waste really...

your phone should not be running at 200MHz when you hit the sleep/power button. So if its in your pocket and the screen is off then 200MHz is not healthy. Something is running in the background. Have you tried the airplane mode battery trick yet? What I did when that was happening to me was...turn on the airplane mode, power off the phone, pull out batt for 20 secs, put batt in and power on phone, turn off airplane mode, then go to CPU Stats and clear it, then put phone back to sleep and let it sit for a half hour or less if you cant handle that wait like I couldnt. Go back to CPU Stats and and click refresh and see if it helped and if your phone went into deep sleep.

Turn Wifi On/Off often causes wear/ tear much more quickly??

Does turning wifi on and off often wear this feature off more quickly? Wear as in it will stop working after an x amount of the wifi turning itself on and off over a long period of time. The reason why i asked is because, in GSIII under Wifi > Advanced > you can choose the turn off wifi when the phone is in sleep mode. This helps save battery and extend standby time.
Wifi would need to be re-established every time when the phone is turned up; and then shuts itself off when the phone is put to sleep. Depending on how heavy i use the phone, my phone's wifi could be turning itself on/ off for more than 30+ times a day. Do you think this will wear wifi feature off more quickly than to leave it on 100% of the time?
In theory the chip will wear out by warming up and cooling down, but under normal conditions - not overheating and not going from freezing point to hot - it will survive hundreds of thousands of cycles.
So even when it switched on 1000 times a day it will last for years, longer than the screen.
No, as there's nothing to wear out. Whatever gave you that idea?
The electronic components shall last longer than your life. Except for the battery, storage and screen only..
Swyped on I9300 - XXDLIB - Siyah kernel - JKay & Thunderbolt tweaks.

Just a thought that i had. I'm really cautious and has thoughts for (minor) concerns like this. Good to know, thanks

Switching phone on using the phone will all result in wear and tear as will using the sound output .Eventually ....
