Is it good to be switching roms frequently? Can it mess up your phone?
As long as u do it correctly each time u should b fine....but obviously it'll b hot if u flash too much....
You can flash as many ROMs as you wish with no worry, it won't cause any hardware problem more than using it a lot during the period you would flash (I mean that gaming 10 minutes is as bad as flashing a ROM for the device) so there is no problem. You will just be wiping quite often to keep it running smoothly.
Actually flashing a rom only formats different partitions which the memory is made for as it is made for read/write files. There is even almost no CPU usage I think since roms are simply zips extracted to the right partitions.
Happy flashing

Actually memory tends to wear with constant formatting and writing, but once he doesn't flash it every five minutes for the next couple months, it's gonna be fine.

Okay then It's different of regular HDD we find usually in computers. True that we don't call it ROM with no reason but I remember I read an article stating that the actual drives used for ROMs are supporting thousands of writes... But with a little calculation once per five minutes for a few months makes kind of 60 000.

I'd love to continue the discussion, but if we get too in depth into this convo, some users may get scared for no apparent reason, so I'll leave them with your last words.
I need some help. I want to make all of the pain go away and send this POS out the window of my vehicle. It has been a cause of so much frustration over the last year.
Most recently, I installed Santods excellent official ICS deodexed debloated ROM. I didn't notice the issue I'm having now before I installed that ROM, but I have since installed another ROM (Jellyblur) and my issue has not disappeared. It started when I was using my camera... i noticed a long delay after I impatiently hit a button while it was thinking. it shutdown. upon restarting, battery went from fully charged to maybe 20%. A couple pictures later and it shutdown again and upon restarting showed maybe 3%. It's not just the camera that causes it... GPS, browsing, calls etc. can all trigger this behavior. After showing a battery level of 3%, I plug it in and it is instantaneously at 65% or 72% etc., but never showing that its in need of a full recharge.
Is there a chance I screwed up something that "tells" the battery it's time to shutdown? Here are some logs from the most recent episode.

&
https://www.dropbox.com/s/qj19s4tegj0bdtc/1363286210391.log
Any input would be sincerely & greatly appreciated. I'm mentally exhausted from this device.
Same thing happened to me quite awhile ago,I think it's just a dead battery.After switching batteries the restarts stopped.

Here's why I am still reluctant to believe it's the battery.
1. I was getting a full day of normal use out of it the day before I installed the new ROM.
2. After achieving a total drain of the battery, upon plugging back in , it shows the charge is already at + 50%.
disclaimer: I have no prior experience with owning a smart phone and dealing with batteries, so I have no idea how they are supposed to act. Limited experience flashing ROMS and no real knowledge of common problems that can occur when flashing etc. etc.

2 Things to consider. The rezound battery is all that is available atm and it is rated at 1640mah vs our 1400 mah.
A new battery is usually not more than 20 dollars
If you are having these problems ensure you are following the suggested directions.
Install ICS Radios
4ext Recovery
Wipe all except sd card
install rom
I have returned to GB rom and i stay on the ICS Radios with 0 problems. So no matter what rom you install i would suggest the new ICS radios. I have installed the new radios in 3 other phones besides my own with 0 problems crossing ICS radio with GB ROM.

I will mail you a thunderbolt battery I have left over when I owned one. So you pm me your address and I will mail it free of charge. That's how sure I know its your battery. What you have to lose? If its not the battery then you got an extra battery.

I own my one X about 300 days now flashing a ROM every 2 days so that's 150 flashes at least and the performance is still much better then the day I bought it. Maybe the battery doesn't like it to much but that's because the one x needs to be connecting via a PC to flash a ROM so that's a lot of connecting/disconnecting the battery.

Your friend is wrong. Straight up wrong. Flash away
The quick answer is yes, the long answer is you don't need to worry about it. Repeatedly wiping and flashing the partitions will over time have an effect. The flash storage used in virtually all mobile devices can only be written a finite number of times. I know a dev who have to be careful of which kernels he flashes because they have bad blocks and only a real slim one will fit now. But it is a 3 year old phone that has been used heavy by a developer. A heavy crack flasher will likely never even come close to flashing as many times as a dev working on a rom. If you flashed a different rom everyday, you should be perfectly fine to last through several years of use.
As for battery, flashing roms has ZERO impact on battery integrity.
I had to have flashed my droid x and droid 2 and droid 2 global once a day at least for about 2 years except on weekends. When working on ROMs and mods I didn't have a choice. But my DX and d2s still run great to this day.
And the entire time I ran those they were overclocked from 1.0ghz to 1.25ghz daily with no thermal throttling. If anyone was going to burn up their phone it should have been me.
My gs4 is following suit. I flash a lot because of projects. I don't expect to have to buy another but I already have began planning on it. The hope is I won't have to and that money can buy the next phone.

I can't help but laugh at the question (please, no offense intended). If this were a real concern most of us here would be in a bad way.
Once it hits 100 flashes, it will start sending Verizon a text saying you are flashing custom roms, then they sent the flash police to your door, be careful.
The Ax says, not true.
On my G3 back in the day, I must have flashed it hundreds of times, np.

and this is what i've also learned from my years of flashing. yes it'll affect, but you'll most likely never get around to the point where it'll make a difference.
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..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

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?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.

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.

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.

The reason i'm here, is because i've just realized, that i haven't had my quick fix for some time now..
Everything seems so stable, except the *mic* issue, but hey, i fixed it with a hands-free.. Otherwise, i'm very happy with my phone, it works, it doesn't use up that much battery, and it doesn't crash, you can even do normal stuff to it.
But to the point.. I really, REALLY miss AOSP, especially the theming.
I can live with the occasional bugs, though i wish it could be at least somewhat stable.. *You know, im not that picky*.
But the one thing that keeps me from using AOSP; is the camera app from Sony, because i like taking pictures of my son, and the environment..
Are there any Camera app out there comparable to the Sony equivalent?
Oh, the urge..

I have the same urge, I wanna get the full output from my Xperia Z2, feel all those four cores working in my hand. But that one Sony Camera app stops me because it's beautiful. It's matchless. That's the only reason I'm not changing my ROM and be bound to what Sony's put in my phone.
I am in the same boat here! I want to flash PA so bad especially with all their features but then the camera app, the noise cancelling features and x-reality etc is really stopping me from doing so
i use to be in the same boat before i noticed there is no point to flashing roms when im on a rom which does what i want
perhaps you should find a rom which has what you want
Same here.I literally used to flash a new ROM on my Nexus 5 everyday. As has been said though, the stock Z2 ROM does everything I want it to and rooted with some xposed mods its perfect.I just have to learn to live with my phone the way most other people do.
just a note
formatting then writing a rom to your system slows your device ALOT, it also cause alot of other issues but that comes after long wear n tear

I remember reading somewhere years ago that flashing new firmware over and over will eventually wear out the hardware and cause it to slow down/eventually fail. I can't seem to find anything for this when searching though! Would it be possible for you to shed some light on what I should be searching for or what causes this issue?
Thanks in advance!

there is something called read/write cycle life
you can only write info so many times onto a disk before it wears out and stops working
formatting a partition takes a huge amount of cycles, installing roms does the same too because its alot of data that has to write

From what I read on the link, it says most flash memory have a P/E cycle of around 100,000 and from what I can remember, it varies depending on the type/quality of the flash memory used (Nexus 7 2012 had rubbish flash memory which a lot of people complained about). Just going off an assumption that the Z2 has a P/E cycle of 100,000, wouldn't it take quite a lot of ROM flashes before the memory deteriorates? Or is it more due to the size of the data being written/erased than the amount of times it is being done?
Sorry for the questions, I know this isn't the thread for it but it is interesting to me!

I used to flash a lot roms everyday on various devices. I didn't notice any side effects of it. As I know a little about hardware there is nothing to fear. You can imagine than one memory cell is one bit of data. If it withstands 100 000 writes it literally means that you can save data (eg. flash rom on it) 100 000 times. There is no way that you can cross this number even with everyday flashing. And it doesn't matter how much data we are writing because each memory cell deteriorates individually, so if we write on 1000 cells it means that every cell will deteriorate only by one write operation which means every cell will still be able to be written 99 999 times.
Another thing is that the storage memory in smartphones is usually one chip which means that all your data including /system partition (which you overwrite during rom flashing) and your photos and music on /data are on one physical device. The conclusion is that if you are afraid of rom flashing and wiping you should also be afraid of saving photos to internal memory. And since we are using our int. memory and change files placed on it a lot it means that we can flash roms as we please without consequences.

Thanks for the thorough explanation. I had my suspicions this would be the case and you've driven it home by explaining the whole music/data/pictures scenario. I used to flash PA and other roms on my N4 more often than I care to count but I never once saw a decrease in performance so it's good to know (personally and for others) the phone's read/write performance is not going to be realistically affected! :highfive:

I've flashed previous android devices ( HTC magic / Desire HD / SGS 3) 100+ times each with no obvious slow down, my albeit limited understanding was that NAND chips where rated for 100k+ P/E cycles?

Correct from the wiki link provided a few posts ago:
"Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles before the wear begins to deteriorate the integrity of the storage.[21] Micron Technology and Sun Microsystems announced an SLC NAND flash memory chip rated for 1,000,000 P/E cycles on 17 December 2008"
