Rom that implements Ultra Power Saving mode? - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

I don't have this tablet but want to get it, although I would love to use ultra power saving mode. Has one of the developers created a rom that allows this tablet to do that?

i see why this is a great feature for a phone that you need to keep connected to the network when the battery is almost dead so you dont miss anything and stay connected but what would you do with your tablet in this mode?

Well, one way I can utilize it is that I can use tasker to turn on power saving mode while my tablet is asleep and turn it off when my screen turns on. Essentially, I want to find a rom that supports UPSM so I can save battery life on my tablet. I plan on using the tablet as much as possible in school for notes, studying, and many other various things, so I want it to last and I don't want to worry about it.
My current tablet is the Asus tf300t that received alot of praise for its combined 15 hour battery life. Since that tablet is slow and slightly outdated, I need to find a new tablet that hopefully can get me through the day with no worries (like my current tablet). I don't plan to buy the Asus tf701t because of its cost and manufacturing flaws, and Asus's lack of support. I want to go with samsung because I haven't had any serious problems with my Galaxy Nexus (aside from horrible battery life) and the Galaxy S4
Essentially, that is why I want Ultra Power Saving Mode, so I can save battery life on my tablet while on the go. So, is there a rom that has that feature in it?

how much battery life would it realistically save, as the Tab Pro has LCD. It makes more sense having it on the Tab S because of the amoled screen having better battery life with black tones.

The 10.1 has a Power Save mode. See screen shot. I haven't used it. Not sure about Tasker interaction either. Just wanted to let you know about this built in feature.

JuiceDefender on Nexus

Some people swear by it, but then again some people believe a supernatural being exists because someone said so.
Yeah I've used it since I got the Nexus and it works great. Does what it's supposed to do. I don't believe in supernatural beings though.
Full disclosure; I have had this bug which manifests about once every week where the touch screen becomes completely unresponsive in the lock screen and there is no way to unlock the screen or turn the phone off unless I pull the battery. I have this nagging feeling that it might have something to do with JuiceDefender but I haven't confirmed it.

I purchased JuiceDefender and also Green Power Premium and never really noticed a big difference in battery life against leaving them off and changing wireless profiles.
Getting almost 2 days out of my Nexus so may give them a go once they both fully support ICS just to test.

Disable JuiceDefender for a week and see if that bug still exists. If not, problem solved. You can do the same as juice defender by pushing the multitask button and swipping away any apps you don't want.

JuiceDefender is not only great for a little energy saving, but also for featured like WLAN by localization and display Brightness configuration.
I used it on the S2 and now on the GN.
On Ics it has some little bugs yet, but it also does seem great job here.
Sent from my Galaxy Nexus using XDA App
I have the basic version of JuiceDefender running on my GN and I swear its making a noticeable difference in battery life.
I have it set to disable my Data connection whenever the phone is locked. It re-enables it when I unlock it, so it doesn't come on when I'm just checking the time. The effect is immediate too so data is there when you need it.
It also comes on once every 30min just to let apps/email sync briefly.
According to JuiceDefender its improved my battery life by 1.7x. I'd be inclined to say its about right...

Lol it does a bit more than that mate. It's the radio function management I need since I'm always too lazy to toggle them manually. I've been meaning to disable it to test if the lock screen bug would go away but I find it hard to use my phone without it now that I've got so used to it. Now that's it's the Christmas holiday though I might give it a go.

It made a big difference in battery life but it takes way too long for the device to reconnect to the mobile network when i wake it up. Likewise, it will not allow me to get my emails throughout the day unless I wake it up.

The multitask button doesn't kill apps - swiping just removes them from the list. Its more like a recent used apps list - like long pressing the home button on Android 2.x use to be - than a multi task manager showing running apps.
As for juice defender, I bought ultimate, and it was just horrible. Very laggy UI, and felt like it was causing more battery usage itself than saving. The comments for 'ultimate' on the market seem to say the same thing. The free version seems much better, although you don't have as many options. There's also another paid version which is cheaper, but I havent tried it.
Put it this way, I uninstalled it Waste of £4.99 which is a ridiculously hefty price for something that cant even get its UI right.

I can confirm the same behavior on my phone with JD, forcing a battery pull a few times a day. after uninstalling it, I get no more unresponsive screen. I can only conclude that it wasn't playing nice with ics

I hope Juice Defenders Team will optimize JD for Android ICS, because I loved the program for its features.

yeah some little quirks BUT, definitely prolonging my battery due to wifi/mobile data management.

i'm getting more than 16hrs on my phone.
as for ultimate. no need for that unless you have a rooted phone.

i picked up th pro version for $0.99 when it was on sale.
JuiceDefender Ultimate
Hi,
I'm using it on my rooted GN 4.0.1, works well.
By using 3G/WLAN management I come up to 25 - 30 hours lasting battery power.
At home and in my office I told JDU (JuiceDefenderUltimate) to switch to those WLAN's and disable 3G there.
I'vnt tested all the other features like cpuspeedcontroll, or something else.
For me it works perfect.
regards
J.M.

Steps to prove yourself incorrect:
1) Install OSMonitor
2) Open GMail
3) Go to homescreen and open OSMonitor
4) In the process list, make sure GMail is listed (it should be!).
5) Press the Multitask soft button and swipe away GMail.
6) Check for GMail in OSMonitor and it will have disappeared as it is no longer running.
Magic!
Sorry I'm just on a personal mission to stop this misinformation from being spread.
---------------
On-topic: I've used JuiceDefender Ultimate on all three Nexuses over the years and I certainly think that it makes a big difference by turning wifi off when not in use and turning mobile data off when the screen is off, although I have loads of other settings configured within the app also.
JD Works Great
I have been using JD Ultimate on my Nexus and it works great (I would estimate 1.5 - 2x battery life).
I used the Nexus for a little over a week without JD just to have a set expectations of what my battery life is without JD.
I have not seen any bugs with this up til now.

I get the same issue and I dont get it when I uninstalled Juice Defender
My phone also reboots randomly and I am wondering if its linked toJuice Defender. The reboots only started recently
I use JD free on my GN, although I haven't seen what battery would be like without JD on it. On my Incredible, JD made the difference between not getting though a single day to getting almost 2 days out of my battery. On my GN with JD I'm still only getting about one full day's worth out of it, sometimes not quite a full day.
I am using Juice Defender Plus and it is set to manage it self then WiFi and 3g network. I am using wifi at home and in the office,and the rest -3g
In my opinion....jd plus does worth the money spent.
14 hours and 20 minutes used - 46% of battery left

Ice Cream Sandwich seems to do a lot of the things that JuiceDefender did on my old phone. For example, data is automatically turned off when you are connected to WiFi. I had it installed for a while, but when I looked at the list of apps that were using the battery (in the Android settings menu) JuiceDefender was listed as using a fair amount of battery. I'm not sure it is worth the hassle on this phone.

HTC ONE X wants..... (non AT&T)

Hello peeps..
(Sorry in advance, this is just frustration.. but I still hold hope)
I upgraded and paid quite a bit of money on top to get this phone and now I am having my face rubbed in the dirt by other devices, ala 4S and S3 .
I know there is an hardcore Android following out there that are keen for things to be exclusively over-technical... but I've got to voice these frustrations...
1: Rooting your device for anything that is remotely useful.... I would root if it was easy enough and I could restore easily without trace to avoid warranty issues.
2: Only a third of the system memory is ever free at the best of times..
3: Battery issues... Do I need to mention them? Takes far too long to re-charge.
4: So much runs in the background and apps that you think you have shutdown in fact haven't.
5: Numerous app requirements not satisfied (mostly due to issue 1) I would like the camera flash to add to my SMS notification, I want different notification lights other than green and red, flash integration with fun apps just doesn't work, I want a call recorder that works and also want a screen capture that works.... a better app management system would be nice.
I know, what a gripe... sorry guys.
Anyway feel free to shoot my points down or advise.
Thanks.
Just wait a while before rooting at least for 2-3 months so you know your phone had no defects because it will void your warranty and wait for the 2.xx update, it will really be good. I am already on a 2.05 custom rom and the performance difference is huge....
Rooting is easy in my opinion and battery problems are nothing but normal with these powerhouses
I charge my HOX as often as a mate his 4S...

Hi Flo95, Thankyou for your reply.
Whilst rooting maybe easy, yes I have seen a few ways of doing this, but I haven't found a way of doing it without the opportunity to revert back to the shop bought system and thus not jeopardise the warranty.

Just with your point on screen capture, you can just hold and release Power+vol down, or hold power and tap the home button. Both will screen capture.
Unless you are talking about video screen capture, then I have no idea lol
Edit: Also my battery isn't too bad. I just charge once a day with moderate use. And I bought a 10,000mAh external battery to recharge when I use the phone really heavily. My gf S3 battery is about the same with her usage and same with her iphone 4 before that was get the same battery life as my HOX (even though it is only powering a tiny little screen and single core)
Some of the issues with compatibility will come in time. I had a swap to a g3 and despite the lack of upgradable memory or battery I took the HTC over the Samsung. I have a 2200mah powerskin and get about a day out of the phone with moderate use. A good hammer means a second charge or perhaps use the Powerskin. At work when it's not in use I just put it on charge.
On the topic of batteries. For some reason every phone I have had since my HTC hero the batteries have only lasted one day. IPhone 2 3 and 4. HTC desire hd g2and 3 and now the one x. All with different screen sizes and all getting different levels of abuse. In fact I use my hox for more things and the battery life doesnt disappoint too much compared to my wife with her 3gs and she never uses the internet just texts and kik and charges hers every day.
Slightly off topic but I think back battery is the nature of the beast now.

1. That will take S-OFF.
2. Any phone that doesn't have 2 GB of RAM has this issue.
3. Make sure you're charging with the OEM cable and use an AC charger. BetterBatteryStats will diagnose battery drain issues. 2.05 should increase battery life and reduce heat output of the T3.
4. Apps run in the background, it's a fact of Android. Just make sure they aren't holding wakelocks or using enormous amounts of CPU.
5. Camera flash to SMS notification is probably a Tasker profile, there are only green and red LEDs in the phone, flash plugin integration has always been poor on Android outside the browser and camera LED flash is not meant for continuous use, call recorder will work with root and a custom kernel for 2 wall call recording, and screen capture is just power button and home button.
App management isn't like the iPhone, but it's not horribly bad, it just uses the stock Android application manager.
If you're not happy, grow a pair and go get a new phone.

You are most definitely on the wrong forum because 1.85 is a HTC One XL (Emphasis on the L part) ROM. Don't update if you want to root, even if you aren't sure. If you don't know whether or not you want root you can always root first and revert later.
You don't need ROMs for themes. Not many people theme the ROM anyways.

Do you use your GS3 to it's FULLEST or are you more of a battery conservative type of person?
Meaning do you have Google Now on (with all location services + even GPS ON), do you have S-Voice enabled and all of it's features, and do you have all the TouchWiz goodies (motion, Voice Commands) enabled? OR do you play it safe so to speak, and turn those features on strictly when you need them?

I use to do that. Then I would carry around 2 standard batteries, but it'd get annoying charging one every night... so now I have my Hyperion extended battery and usually I go 2 days without charging my phone on moderate use.

I only got the s3 because it was up to jellybean and I saw cyanogenmod supported it. Looking back I am sorta wishing I got the galaxy nexus.
The only real Samsung "feature" I use is some camera options, and the slide to call. Other than that, I might as well use a stock droid phone. My battery last pretty well. In school I use my phone moderately. With that said, depending on the day, around 5ish my battery can range from 80%-60%.

I leave literally everything on at ALL times (except bluetooth cause I have no use for it), the only time I shut anything off is when I am at work and I get ONE BAR of 1X, I will shut off data.
I have google now fully running, but I don't turn on wifi/bluetooth/gps until I need it. Guess it's just habit from trying to save battery on older phones.
I turn everything off but I don't go airplane mode. I will turn anything on if I need such as data WiFi Bluetooth gps. Have it on ondemand governer nothing special at all. Put it on I get a good day and half of just like texting calling checking the web every once and while. But I just orded the zero lemon 7000 battery so I'll probably use it full maxed out everything and won't have to charge besides every other day. will probably have it at performance governor an see if I can start a fire in my pocket haha

The two biggest power users are the screen and the radios. So, manually tune down the screen brightness and sleep timeout. Then install an app like Juice Defender to manage the radios. Done.
Getting 24-36 hours on a charge isn't hard. Getting more than 2.5 hours screen-on time (Android 4.0-4.2) or 4 hours (Android 4.3) is.

i don't use "battery savers". But i do use greenify and an autostart manager. For me,it's normal to have 3.5+hrs of screen. never had less. It's also very important the signal strength.Weak signal means high drain. If you don't use data(3G/4G),it's better to go for 2g network.It consumes alot less battery.But i just can't imagine someone buying this phone(or any other super smartphone) to stay on 2G only and wireless.

Is Touchwiz really slower than stock Android?

We all love to rag on Touchwiz for being a bloated lag beast and pray for the day we can flash CM to get rid of it. However, there is a way to compare stock Touchwiz vs stock Android on two devices with exactly the same hardware specs and surprisingly, the difference is not that significant.
The takeaway is that Touchwiz seems faster loading video while stock Android is faster loading web content - I have a theory for this based upon how Touchwiz parses javascript, but that's another thread . On a benchmark basis the two are within a few hundred points of each other.
Anyway, here is an interesting video of a guy testing the S4 Play Edition (pure Android) vs the S4 Touchwiz Edition, both all stock and brand new with no rom optimizations or debloating. It's interesting and shows that while stock Android may be a bit faster overall, the difference is far less than one might have imagined. Of course the results may be different on the Tab S.
Nice, but surprising report. Guess the skeptics will need something else to complain about.
Sent from my SGP512 using Tapatalk
If only those 2 models were comparing Exynos vs Snapdragon.....then we would have a better understanding.
But I can say for sure, in daily use, Touchwiz is noticeably slower than stock.

The thread is about TOUCHWIZ Vs ANDROID not Exynos vs Snapdragon. In this test anyway there doesn't appear to be much difference between the 2 running on the same platform. YMMV.
Apparently, Kitkat 4.4 introduced aggressive cpu throttling at much lower temps than prior Android versions. This may be something that is causing slowdowns you have perceived with prolonged use. While this increases battery life, it crushes performance. Fortunately a good kernel should be able to address this. In this case the hardware is fine, it is the OS which is screwing things up. I guess Google saw that people care more about battery life than blazing performance.
Anyway, here is the article. Interesting.
http://www.tomshardware.com/news/sa...at-performance-cpu-throttling-dvfs,26414.html
Again this is for the S4. Not sure how it applies to the Tab S.
Here is a thread by a dev who was able to disable the DVFS throttling on the s4. He claims that is to blame and not KitKat directly. Will research to see if thee is anything similar for the Tab S.
http://forum.xda-developers.com/showthread.php?t=2674928
Ok, I see that using Wanam Xposed you can disable Samsung DVFS in Advanced Settings. No idea if this works on our Tab S but I disabled it and nothing seemed to break on reboot. This should not increase benchmarks, just stop excessive throttling. One would guess you will see better performance and worse battery life.
We'll see.

Hi Mitchell, did the battery life turn out worse?
Still deciding whether to root my tab our not (root loses a tv streaming program in belgian which is quite handy)
All I have to say is load up my alpha rom and see for yourself. It's like the difference between a tablet that came out this month (CM) and a tablet that came out three years ago (TW) performance wise.
I've gone from thinking about selling it to wondering how many years its going to be before they can produce a tablet that makes me want to upgrade.

Soon as you're ready to pop out an 800 I'll be on it.

There is a pre-alpha build up for the t800. Unfortunately I don't have one to debug but I hear it boots, touch screen works, but no wifi.

Oh cool. I'll hold off on trying it until WiFi gets going but will watch for it.

It will probably be a bit. I don't own the 800 and mainly posted that to show it was possible. If I finish the 700 before the baby is born and no one else has picked it up then I'll try to get it finished.

Hi Mitchell, did the battery life turn out worse?

You can use rootcloak + xposed module. the tv streaming app will not detect your root.

I guess Google saw that people care more about battery life than blazing performance.

Yes and this is one reason why I get sick of people moaning about battery life all the time. It's a mobile device constrained by current technology and what size battery can be squeezed in.
Yet people still expect 3 days battery, super duper speed and a nice slim light device.
For me I accept the limited capabilities of a battery in a mobile device and think they do a pretty good job as it is.
I want a mix of performance and battery, but I'll gladly sacrifice a bit of battery life for a lag free , smooth device.
However the more people moan about battery life the more the scales will tip to battery life at the cost of performance.
I would be willing to except a tablet a mm thicker to have a bigger battery

you can use a root hider application to hide that application from root
