hmm i heard alot of people telling it saves alot of battery power.. jus wanted to know about the pro version..
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] winthur:
Yeah it does save quite an amount. You can configure it to on off Wi-Fi necessarily or learn specific network when you are on the particular area of interest.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] freedomispopular:
My previous phone was pretty crappy and I had pretty crappy service, so I had to make sure I turned wifi, mobile data, etc. off when not using them. On my Note, I don't even bother turning them off because they drain so little. I don't think bothering with Juicedefender is worth the trouble.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Markuzy:
Had an old Xperia Arc and Juice Defender worked quite well to last me the day.

Now with the Note, I tried with and without it and I find no significant difference actually.

I agree...

Being new to the android and rooting scene. I downloaded all the recommended apps and one by one uninstalled them including juicedefender...

Whats the point of it stopping data when screen is off? It defeats the purpose of push notifications.

Also I didn't notice any real extension of battery life either
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] NikosPx:
I think it depends how you set up juice defender ultimate. For example on weekdays and working hours I use the "peek" option, letting jd enable connection every 5 minutes. Of course I have than battery drain. With different settings on different times and/or days (up to flight mode at night) I have significant less battery consumption.

It is also important when you use your phone a lot with the screen on, not to let jd automatically turn data on, because then there is obviously no difference at all, with or with out jd running.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Unamrakerag:
There is no use of such apps, I have tried used many such apps from my S2 days and I never felt any difference in performance or battery life..just let it go. Ur using an Android device, and if u use it as a smartphone should be used, u will need to charge in at least once a day.

I had used JuiceDefender for a short spell when on GB. However, BetterBatteryStats soon showed what a battery hog JD was, so I made it disappear from my phone. Forever.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] dr. xp55:
Exactly. Juice defender is crap. Its just for lazy people who can't maintain their settings on their own. and juice defender is obviously always running in the background, using up cpu power and draining battery on its own
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] zen0s:
It does save little battery and drains at the same time. Huge down side of using this kind of app is no push and data connection is glitchy, sometimes takes awhile to connect back to network or wifi and slower performance. I can still use gnote all day with single charge so I don't find this kind of app useful to me at all. It's really not hard to turn off and on data or wifi on android unlike ios crap where you have to dig in settings.

Save few % battery vs slow performance, hit or miss connection.. I think answer is simple :p
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] andreww88:
I used to use it, ultimate version. But I quit using it and still have great battery because of my own setting changes. Juicedefender might be okay for people that don't use their phone much. But, if you are constantly on it, like I am, it is just a memory and battery hog.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] salespalace:
Its not worth it, and possibly wastes battery juice rather than saving it.

I've been using it for several weeks now, when i go to sleep my usual percentage is from 70 to 85 % i always turn wifi off as i don't charge it at night. With the app running in the background, when i wake up it goes down to 45% when i do not use it as in its not running in the background I'm the morning the battery percentage only hours down by 5% max to 80%.

battery saver is better
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] kyrirhcp:
Don't bother. I used it on my HTC Flyer and I saw no difference. Migrated it to the SGN and I saw a huge difference after I uninstalled.

The features are limited and just stupid if you ask me. I believe the best battery app would regulste connectivity on demand (ie when I open Dolphin or refresh Facebook it would connect automatically and disconnect immediately afterwards).

If you are looking to extend battery life I suggest self regulating your connectivity (ie use the toggles) and screen brightness.

For even better battery life try and avoid apps that constantly run (eg ones that monitor other apos and processes).

You should get very decent life out of the SGN, and if you don't do what I did and get a spare battery. They are cheaper than you might think and they are an absolute life saver in emergencies or times with heavy usage.

Hope that helped

It's not going into deep sleep. Try a reboot or you phone is plugged on a charger then it doesn't go into deep sleep neither.
[Galaxy Tab Q&A, Help & Troubleshooting] bdsmchs:
Alright, so I've got a rooted Verizon OG Galaxy tab (SCH-i800). For the last couple months I've been running this ICS ROM:

-------------------------------------------

http rootzwiki dot com slash topic slash 11697-rom-cdma-aosp-ics-cm9-build101-0418

-------------------------------------------

A couple weeks ago, I plugged in my tab to charge and went to bed. When I woke up in the morning, the tab was powered down. I powered it back on, and it took at least 15 minutes to boot and when it came up the system was giving a warning that it tried to convert the system to an encrypted system and failed. It then said to hit "ok" to format data and reboot factory-fresh. So I said "ok" and tried that. It booted up into the same error screen another 15 minutes and just kept repeating this every time I tried.

So I went into CWM Recovery and tried to do a manual wipe data/cache partition from there. It also appears to have failed.

Lastly, I tried using Heimdall to reflash the tab to 2.3.5 rooted (where I started before the ICS ROM). When I do this, the tab boot-loops at the Verizon Wireless animated screen. If I go into stock recovery I get this error message immediately upon boot:

http i dot imgur dot com slash DSuyt.jpg

If I ignore that and select "wipe data/factory reset", then I get these error messages:

http i dot imgur dot com slash Ofr8s.jpg

As best as I can tell, the /data partition is messed up in some way. I'm GUESSING that due to the encrypted conversion, it's probably no longer formatted as ANY kind of filesystem so linux can't mount it.

I'd love to be able to fix this, but when I plug the tab in to my machine (Win7 64bit), adb doesn't see it.

Could REALLY use some help here. Thanks guys.
[Galaxy Tab Q&A, Help & Troubleshooting] yappoe:
Wow that's pretty hard core. Failure to mount cache could be a serious problem. Hopefully someone else can jump in and help as well... I'm afraid there could be a hardware failure. I.e. You may need to go to Samsung to have it repaired (replaced).

Some questions about how you flash to stock 2.3.5:

Did you repartition (flash pit file) when you restock your tab? -- and a just-in-case question -- You did choose a CDMA version of 2.3.5, right?

For the undetacted problem, you need to retry several (or many) times while odin (or heimdell) is started. Sometimes Odin (or Heimdell) will detect the tab before your computer can detect it as unrecognized device.

If you can go pass this detection issue, try to flash cache.rfs from a cdma ROM.

I hope this can solve the problem.

If not than it is almost 100% chance hardware failure, and SAMSUNG service center should know what to replace (I imagine it's the internal SDCard).

Good luck and I hope you are still under warranty.
[Galaxy Tab Q&A, Help & Troubleshooting] bdsmchs:
I did not re-partition. I've never been able to find a VZW PIT file, and the PIT's that I've found (Sprint CDMA) I could never get Heimdall to do anything with. I'm sure I've been doing something wrong.

As far as a CDMA version, yeah. I'm using the VZW 2.3.5 Stock Rooted to go back to stock with Heimdall.

I've never actually had any real problems with Heimdall recognizing the device (as long as the drivers are installed right) and flashing the firmware. The problem is just trying to recover from this /data corruption.
[Galaxy Tab Q&A, Help & Troubleshooting] yappoe:
I just edited my earlier post.

Try to repartition with a pit file. Moving from ICS to Gingerbread requires different partition system (the EXT to RFS) -- This might be the problem. You can do it with ODIN easily. I'm sure you can use Sprint's PIT file without a problem.

Try that first, if you still have mounting problem, you need to find both dbdata.rfs and cache.rfs from a good CDMA rom.

If after you replace those three things, and you still can't boot it up.. you may have, as I said eariler, fried some hardware.

Hey, read this guy's post. He downloaded pit file available with the heimdell and he has verizon tab.

[Galaxy Tab Q&A, Help & Troubleshooting] RichAP:
I'm having the same issue with a friends VZW Tab and I believe the Data partition is screwed up and is in some sort of read-only mode.

I am able to install different roms but can never wipe the data(or cache) partitions.

Once I installed ICS I got the same encryption msg as you.

I think there may be a way to create the data & cache partitions on an SD card.

The other option is replacing the internal flash chip.
[Galaxy Tab Q&A, Help & Troubleshooting] PookiePrancer:
Did you ever get this sorted out? I can't believe ICS roms can fry a device so badly. From what you wrote, it looks like I'm in the same boat, but all threads lead to nowhere.
[Galaxy Tab Q&A, Help & Troubleshooting] ableeker:
This sounds like the ICS Encryption Unsuccessful bug. There are reports of Captivate owners (and probably others) who have seen this message at boot, and were left with broken phones. It seems the internal storage was permanently broken or at least locked. So far there's no real explanation what's causing it, or how to fix it. There's a workaround, switching the internal storage with the external storage. I don't think Tabs have been damaged permanently, However, these reports seem to occur more nowadays, so some may have been burned. I've seen this message a couple of times myself, but the Tab was working again after reboot, though it did a kind of factory reset every time. However I noticed it seemed to occur more frequently the longer I was running ICS. Restocking to GB with Kies even failed initially, and only succeeded with an emergency recovery. For the time being I've decided to stay with CM 7. I do hope JB will fix it, and it will be safe to run it on the Tab.
[Galaxy Tab Q&A, Help & Troubleshooting] PookiePrancer:
I can get into CWM recovery and put the Tab into Download mode, and the battery takes a charge. I refuse to accept that a spontaneous encryption could brick a device. I'm going to try this, though I've never used ADB, so I have a lot of learning to do (any help would be appreciated still):

[Galaxy Tab Q&A, Help & Troubleshooting] DaKillaWilla:
I find it very interesting that people that converted there tabs to mtd to run ics are experiencing this issue. Has anybody experienced this issue running a stock rom?
[Galaxy Tab Q&A, Help & Troubleshooting] PookiePrancer:
Not that I've seen. I was leery about trying something like this, precisely because it requires a change from which you seemingly can't recover. Everybody says "restock with Overcome." Welllll...that doesn't work for the CDMA Tabs (wish I knew that before). I've had the Tab since it came out, so it's not a terribly painful loss, but I certainly would have preferred it not happen. Now, I'd be tickled pink just to get the Tab back to stock/unrooted :)

I still haven't tried the technique in the guide I linked to (have a lot to learn about adb).

Oh, and bdsmchs moved on. He got some help on rootzwiki which indicated his Tab was physically damaged after his ICS upgrade, and apparently had insurance to cover a new one. So...word to the wise.

I don't think my Tab is as bad as his was, but we'll see.
[Galaxy Tab Q&A, Help & Troubleshooting] DaKillaWilla:
Try odining the sprint stock tar with its pit (repartition checked), and see if that brings it back. I notice alot of people running ics on the tab have said that it gets warm and the battery drains while its off. Mine was doing that on ics, so I figured something wasn't right. So I went back to a sprint stock ext4 rom. My guess is its either the ics kernel causing it, or maybe the chips in our tab just don't like the mtd partitions. For me its just not worth the risk. I could probably run a themed launcher to get that ics feel if I want. As long as everything just works I'm happy...
[Galaxy Tab Q&A, Help & Troubleshooting] ableeker:
Just to clarify, the Encryption unsuccessful problem doesn't have to do with encryption. What happens is that during boot the Tab is unable to read the internal storage. It then assumes it must be encrypted but is naturally unable to decrypt it. It then gives up with the EU message and tells you to reboot. However, the internal storage failure may be caused because ICS uses a function that in combination with a bug in the controller firmware that is said to break the internal storage. If the internal storage is broken because of this, rebooting will not work. Unfortunately not even flashing will work. As far as I know this problem doesn't occur on Gingerbread, only on ICS. I've seen this problem a number of times on ICS, and it seemed to occur more and more the longer I ran ICS. For now I've gone to CM 7.2 to be safe, but I'm hoping JB doesn't have the problem.
[Galaxy Tab Q&A, Help & Troubleshooting] DaKillaWilla:
Is the cm7 your running ext4 or mtd?
[Galaxy Tab Q&A, Help & Troubleshooting] PookiePrancer:
In your experience, did you ever know of anyone recovering? It looks like I won't be able to use adb to follow the steps I linked to, since I can't exactly select "USB Debugging."
[Galaxy Tab Q&A, Help & Troubleshooting] priyana:
well, like ableeker said,

the encryption unsuccessful message has nothing to do with encrypting your android to avoid people reading your /data (which is what your link points to).

It just can't read your /data and "think" it is encrypted because it reads gibberish.

In other words, toasted NAND chip.
[Galaxy Tab Q&A, Help & Troubleshooting] PookiePrancer:
Thanks for your insight. Some of the threads I've read pointed to either that, or the fact that the partition had been encrypted, but without knowing the key, you'd never get back into the partition:

"Here's the bad news:

Your partitions for /data and /sdcard are no longer accessible. They may be encrypted with a key you cannot know (completely lost) or just inaccessible (data restoration possible, but not at this time."

So I thought the procedure I linked to might be able to help recover the partition. I have no idea, though, so I'm grasping at straws. Just weird that most of what I've been reading is on custom ICS roms.
[Galaxy Tab Q&A, Help & Troubleshooting] mrnadir:
So did anyone find a solution to this? I also started running cyanogenmod 9 and after 2 days my tablet wouldnt boot beyond the startup screen. Found out through cw recovery that the /data partition is corrupted. I have tried multiple pit files but no luck yet.

One workaround I was thinking was to mount the /data partition on the external sd card and at least get the tablet working instead of throwng away. Im guessing that the internal nand flash is soldered.

So how does mount the /data to the external sd card? a softlink maybe?!

I have been contemplating this situation for months! Now i wanna get the users personal opinion :)

What is your take on the LG G2X? Is it good? I looked at the specs on LG's website and im liking them. But how does it feel being used every day? Is it better or worse than the SGSII?

what are the prices for them is it craigslist, or literally a new like straight from T-Mobile? Overall in my opinion SGS II or wait for a couple months and get the SGS III, or HTC One S now, I say stay from the G2X cause of lack of support from both parties that put the phone out.
