Why Root the Yoga Tab 2? - Thinkpad Tablet General

Didn't see this question asked in thread search, so I'm going to throw this out there:
What are the benefits of rooting - specifically - our YT2s? For all the other devices I've rooted before, the plusses were deleting vendor apps (which in turn helps battery life), ad blockers, root-only tweaks and apps. But from what I've seen and experienced, the YT2 has excellent battery life off-the-shelf, has very few vendor apps (with only a couple of those you can't disable), and can't support most Xposed modules. So what's really the point?
I'm pro-rooting, but this is truly the first time that I'm on the fence.

For me root is a must regardless of warranty. I like the network indicator mod and reboot menu as a standard
For me the battery life is OK. When watching movies/playing games it stays cool but battery drains fast. The charging is also poor. Hope this update helps!
The kernel is still the same build number so I dont expect a great deal

How much/fast does your battery drain per hour? When I watch shows streamed on MX Player via ES File Explorer from my home server (so wifi on), the hit is about 8-9% battery per hour with headphones and screen at 25-30% brightness. That comes to approx. 11 hours of SOT. When I play Star Wars Galaxy of Heroes, for example, the drain is roughly 14-15% per hour, so probably 5+ hours SOT? I've never played that long, so that's just theoretical, but possible as well.
The charging is slow, I agree, but I think it's because we have a larger-than-norm 9600 mAh cell - that's obviously going to take longer to recharge.

what about battery of Iconia A500

hi all
I'll buy Iconia A500
But I heard that the battery life 4-5 hr only
is it really ?
Also learned that it can run USB 3G Modem by patch.. Search for a video on YouTube about this but did not found.. is there video ?? and how much battery life when using 3G Modem..
mmmmmmmmmm
if battery bad
can i change batter?? any tablet battery can be used??
I apologize for the many qestions and my bad language
I don't know about the rest, but my battery lasts about 9 hours of reading e-books and comics, some games (a lot of gaming = about 6 hours). I don't do much video watching, but someone who does can answer that for you..
To answer the obvious, battery life depends on the kind of use you put it to.
Reading eBooks, playing games can be quite draining on the battery. Maybe up to about 7-9 hours. If you light browsing, wifi always on to get mail and do light reading, you could potentially get up to about 50 hours or more of battery life.
Cheers!
thanks for answer
what about USB 3G Modem ??
Best I can tell you need either one of the custom ROMs or a custom kernel file for the 3g USB modems; see the A500 Developer forum for more details. Battery life shouldn't be horribly affected while using an external modem, although you will lose some battery life.
My Iconia tends to last the entire day on a single charge; I leave the WiFi on full time for the most part, and get a couple of hours of off-and-on web, email and e-Reading during the day with a good solid 3-5 hours use at night. I do suggest charging once a day just to keep from running out unexpectedly, but I have had it last two days of light use before when I missed the charger being unplugged...
i cant confirm battery life with a 3g modem attached but without one my tablet usually last about 2 days, thats with wifi always on but with airplane mode on(helps with the cell standby bug for me), 5 hours of display time mostly web browsing, downloading and email usage.

OC to 1.4Ghz,
Full charge before sleep
Wake up at 96% (drop very slow during idle)

So, now, the battery has been off charger for 20 hrs, and the battery is around 50%.
I say 'great' for the battery life.

I believe s-off has something to do with the 'radio' in the tablet, which sends and receives signals. The cell standby bug is that when Acer made the software for the tablet, they never disabled the 3g module that continuously looks for a 3g signal. This is a big battery drain and can be disabled by using an app that will do it for you, if your device is rooted.
I have a question: I have been thinking about getting the a100 which is supposed to come out 'early august.' It looks like the only differences will be the screen size, half the RAM, and maybe the size of the battery(s) they put in the tablet.
Can anyone give me information on how their battery life is while listening to music? Is it a massive drain, or is it nice on the system and not cause much issue?
Thanks for the information!

Hi,
may I know you are using original ROM or which custom ROM?
I am currently using "Prime 9-3" with OC1.4Ghz.
But I can't really get the battery status you share.
So hope to know what ROM you currently using.

I do wish people wouldn't keep repeating this blatant misinformation.
How can there be a battery drain when the cell hardware doesn't even exist? Sure, the app is polling, but there's no hardware there so the ONLY battery drain is the minor amount caused by the app running. What you're seeing in the battery status is merely a erroneous data caused by the app failing to connect to the non-existent cell hardware.
If the battery usage it indicates were true, your battery would be flat in about 6-8 hours. Mine is now on its 3rd day without charging and is STILL above 40%

You can't really depend on having battery life like that if your using it. He's got 20 hours off the charger but it was idle mist of those 20 hours. Me with heavy usage internet, quick games, YouTube I get about 9-10 hours

That battery life though...

Just got the tablet a few days ago. Love the speed. Love the pen. Love the stock UI. Love the tablet. But that battery life..... yikes. I wanted to know how everyone's battery life was. I'm on rooted 4.4.2 and it dies so fast. If I'm not using it, it stays on the same percentage for a few hours but if I'm using it, even for light browsing, the battery percentage just drops. While I'm playing Dead Trigger, it takes like 5 minutes of gaming to drop 10%. I'm on maximum performance so I didn't know if that was normal or not. But thats during gaming on max performance so I can't say I didn't expect that. What I didn't expect however, is how fast it drops even with nongaming use at low battery setting. I was taking notes in class earlier today and it dropped a percentage roughly every 1.5 minutes. Is this normal? What are your battery lives like? Does it get better if I roll back to 4.3 or 4.2.2?

Interesting. So rooting it might have something to do with battery draining so fast? I'll have to try to wipe, reflash stock, and test it out. Appreciate the input!
I have not rooted my TN7( 4.4.2 ), I use BSPlayer for videos and music and my battery shows 1% drop after playing MP3s at full volume for 8-10 minutes. That's very impresssive battery life. I use "Balanced" setting from "Settings" app. May be, you are having battery issue because you might have rooted using chinese method and that installs some chinese apps.
MC4 runs without lags on my TN7 with "Balanced" setting and about 3.5 hours of battery life. I will check what happens after changing to "Performance" setting.

I did not experience any "impressive graphics" when playing Shadowgun THD. What was you experience? (RR3 looks very good, mirroring on the surface of cars, shadows) ...

I've rerooted it from scratch and the battery lasts much longer. The only chinese app I had was some input keyboard one that I immediately deleted with clean master so I wasn't worried about it. I unfortunately have not tried shadowgun THD so I can't say what my experience is, but man. RR3 does look AMAZING.
Mines totally stock bar the google home laucher
I think it is pretty awful
1% every 1.5 minutes just surfing and YouTube
When running root w/ stock 4.4.2-2.1 and power saving mode w/ auto backlight, I get around 6-8 hours of use - I don't game though.
Just picked up the evga version, did all the updates to 4.4.2, battery is just draining like crazy, unit is quite warm to the touch constantly. Topped off out of the box, did the updates, was at 92%. Stepped out with friends and took it with me. It was sleeping the majority of the time, took a couple of test pictures to see AOHDR in effect. No wifi connection. 6pm to 9pm when i got home, battery was at 8% installed a couple of apps, in about 15 minutes was at 4% with the critical warning. Went ahead and charged it up all night. Been off the charger about 40 minutes, im at 75%. This can't be right, nothing near what you guys have reported. battery indicator is that screen on is the biggest drain. Im rooted, stock recovery, SD write fix applied. If i have to do a wipe, ill do it, but i've only installed bgee, sketchbook, cal, coursera, and a bunch of updates. No chance of 10 hours web like the reviews state, no chance of 10 hours of even idle running! Im using the balanced power mode, prism on, auto dimming.

Got Evga, after the 4.4.2 the battery started to drain at aprox. 1% per minute even with the screen off, Seems to be a bug of 4.4.2, maybe the latest update shall fix that. Anyway, personally I won't know it for a long time since I bricked mine while trying to go back to 4.3 and escape from battery drain Also, if anyone could do me a favour and backup the system from cwm, I'd be really happy)
Try deleting the "batterystats.bin" file and then switch off, charge, then power on after complete charging.
I think those who are reporting battery problem, all have rooted, thank god I have not rooted till now!! I can play 720p movies from my shared windows folders over wifi with fair signal strength for about 9 hrs. Still while playing Asphalt 8, battery lasts only for 2.5 hours. I have all the default settings, not changed anything. ( Xolo Play Tegra Note )

BATTERY LIFE: Heavy Use Endurance

Playing Candy Crush for 22 hours straight can take its toll on your battery (and your marriage). Rate this thread to express how the Note5's battery performs under heavy use. A higher rating indicates that it lasts a long time even when playing games, streaming video and audio, and doing other CPU-intensive activities.
Then, drop a comment if you have anything to add!
When using the Note5 heavily, I can get through an entire day...but barely. Like if phone comes off the charger at 7am and I beat the crap out of it with tons of use, it'll be at around 10% by 8 or 9pm. If I'm going out, I just put it on the fast charger and bam, I'm back up to 50% in like 30 minutes.
I'm getting 8hrs sot, with WiFi running continuous, but mobile data off,I'm moderate user,still my previous phone didn't last me a day,but thanks to this phone now I'm carefree about battery,well at least for me the quest for better battery ends

man this phone battery sucks, i use sometimes facebook, and have some news apps , some youtube, email, and bit of this and that
i charge it overnight and leave home at 8 am
and at 7 pm the phone battery is dead that is such a bad battery i wish to know how the people here praise its battery it really is bad
HI Man, it is as same as me
man today it ran out of battery so fast by 5pm it is dead, and i barely used it . Oh man i feel i did a huge mistake buying this phone
i tried factory restting it and still the same
this is so so so bad that i am so missing my iphone which was working great and had an amazing battery life
and add salt to the injury i ended up buying the sm-n920k which is the korean version and this has no rom support what so ever here on xda
i am so disappointed
For those of you that are having a lot of trouble getting through a day, I'd highly recommend this http://forum.xda-developers.com/note5/general/guide-bloating-touchwizzing-note-5-t3184563 because I got at a minimum 150% of my original screen on time compared to when I just got the phone.

I'm not sure what you people with terrible battery life are doing. I hardly used my phone today but it's still been on for a while. Switch to T-mobile and put some cool stuff on it. I am by no means an android expert, but the quest for battery life is how I discovered XDA.
My experience is different. With moderate use i drain about 12% an hour. Then again im on the moar rom with no bloatware running in back ground. But heck even with heavy use. I have yet to see the phone less than 50%.
i am not using my phone when i at work and now 16:15pm. unplugged at 07:00am. total 12,5 hours on. SOT is 1 hours and now phone at %37. Heavy AndroidSystem and AndroidOS battery drain. i tried to use my phone without root for one week but impossible. %5 per hour. Battery graphic is going down everytime!!! This is so stupid!! again i will root my phone and i will use custom kernel and again everything will be fine again.
1) samsung dont know how to code a good kernel
2) without root note 5 is worst multitasking phone with huge 4gb of ram
3) without root i cant even delete that never use and never wanted phones by me (facebook or instagram or other bull****s)
4) without root i cannot use my phone without lagfree( because i must disable or delete some useless apps that allways sits on my RAM!!)
5) i paying lots of money and for use a good phone i must forget my guarantie!!
Thanks a lot samsung! note 5 will be my last samsung phone
Actually we must talk about that! Thanks !!

I get very decent battery life, check this thread.
http://forum.xda-developers.com/note5/general/battery-life-discussion-t3178480
I currently have all of the bloatware running, as well. I used to use Package Disabler Pro, but no longer find that I need to use it for battery life. 99% of the time I am NOT using wifi either.
Things I have done (to the best of my memory):
1. Disabled VOLTE
2. Wifi calling
3. Turn off location history
4. Remove Android Device Manager as a Device Administrator
5. Screen brightness set pretty low, but I have it set to auto as well
Probably a couple of other things I missed, but I believe those optimizations have greatly improved battery life on my phone.
Hope this helps.

i would say this accounts for heavy use...a little bit of everything but.mostly youtube 1440p videos with almost full brightness...some facebook, browsing,games, etc...only wifi. from this point till i reach 5% i ll use only data to.simulate further heavy usage - so i ll update the info as soon as i reach 5% or so...
my config : darthstalker v5, skyhigh kernel 2.6 undervolted by around -100mv on almost everything, if you want i ll post links to the synapse settings from othe threads...and frequencies locked to a57 min @600 max @2400mhz, a53 min @300 max @1500mhz, gpu 266/600mhz. coming up - only data connection from 51% to 5%.
and here s the end result (so basically 49% spent only on wifi and another 46% spent only on data...

[SURVEY] Tab Pro 8.4 Battery Life - ROMs, tweaks and configurations

Hi all!
I don't know you, but one of the main concerns I have about my tab is the battery life.
I don't know, but there's something about your tablet having the same or lower screen on time / battery life that your phone that seems wrong to me.
Anyway, this thread is to share our experiences with battery life, consisting basically of:
1. The ROM we're using
2. The governor (cpu and hotplug)
3. The apps for saving battery
4. Any other tweaks battery related
A print of battery stats and screen on time (sot) would be more than welcome, if not just share the values.
This way we can help each other to squeeze the maximum out of this 4800 mA battery, and the snapdragon 800
Thanks!
I find the battery drain in CM13 odd, for example if you run a game the battery drains at an alarming rate, like 50% down to 20% in 10 minutes, but if you power off the device it goes back up to 50% on next reboot
though perhaps my batt is just getting old now... :......(

Stock QC2 Firmware - Battery tips?

Hi Friends,
Just wonder if this is normal for this phone, or you guys could give me some pointers for extending my battery life, specifically the Screen On Time?
I have:
- Stock QC2 firmware - I believe this is Nougat with the March security patch
- No Facebook installed (Disabled)
- I am on data about 8 hours a day, rest is WiFi, Bluetooth for my Watch, and NFC is off
- Generally use a black and red theme
- Doing Ad blocking with the AdClear VPN solution
- Sometimes I make conference calls of under 2 hours
- No games, no YouTube watching
With this set I can barely manage like 3 hours of SOT. Is this normal? What am I doing wrong? Any pointers? Thanks!
3 hours SOT is not normal for unrooted stock. I would suggest downloading GSam Battery Monitor and finding out what is hogging the battery. Note that you will need to manually enable the battery statistics permission with ADB for some reason, but after that it will work like normal.
The top two lines should be Android System and Kernel. If you see any non-system app in the vicinity, that is your likely culprit unless you can explain it with normal usage (for example, Firefox is at the top of the list on mine because I surf the web with it)
Alternately, if nothing odd shows up, you may have a bad battery.
The other thing you might take a look at is shutting off the Location setting that scans Wifi/Bluetooth. That is a massive battery killer
Thank you for the helpful responses guys! I'll try GSam Battery stuff... What are your SOTs BTW?
Thanks!
Also my vibration is always on, my back lit keys are always on, and a 30 second screen timeout time, if it helps? Thanks!
Finally, this is the AT&T model with all the bloat disabled.
I'm typically off charge 18 hours and on data the entire time. I do run a Exchange email app that pushes email, my SOT isn't really huge, maybe around 2-3 hours and I also have BT always on and connected to my S3 Frontier. At the end of my day, I end up with with battery around 50% ish.........
Did you recently update, or did you do a clean install? Sometimes the battery can take a few days to settle in

That's pretty amazing! Yes, clean install and updated from MM to Nougat and then the latest patch.
I've got a battery monitoring app installed now... Let's see what it unveils... I'm thinking maybe it's my settings, syncing and etc, cause I NEVER get the SOTs people report on XDA LOL, on any phone really except the Mate 9 I had...

I've got a battery monitoring app installed now... Let's see what it unveils... I'm thinking maybe it's my settings, syncing and etc, cause I NEVER get the SOTs people report on XDA LOL, on any phone really except the Mate 9 I had...

I'd give it a few days to settle in.
Battery life is SO subjective. The app's installed and the person's usage habits play a massive part in battery life, and you saying that you never get what others are, speak a lot to that.
The built in optimizers in Nougat seem to do a pretty good job at putting unused battery sucking apps to sleep.

Hi Friends,
Just wonder if this is normal for this phone, or you guys could give me some pointers for extending my battery life, specifically the Screen On Time?
I have:
- Stock QC2 firmware - I believe this is Nougat with the March security patch
- No Facebook installed (Disabled)
- I am on data about 8 hours a day, rest is WiFi, Bluetooth for my Watch, and NFC is off
- Generally use a black and red theme
- Doing Ad blocking with the AdClear VPN solution
- Sometimes I make conference calls of under 2 hours
- No games, no YouTube watching
With this set I can barely manage like 3 hours of SOT. Is this normal? What am I doing wrong? Any pointers? Thanks!

I notice one thing, when i connect my Gear 2 by bluetooth battery on phone less about 10-15% less. With out watch and no FB and FB messenger, NFC on, most of day on data, wifi off, 5-6 hours call ( do to nature of my job) i get around 3.5 hours SOT.

I agree bud, so I think my usage pattern must be horrible, cause from the earliest Androids like Droid Incredible to Axon 7 and S7 Edge and others, I never get what people mention. And some of their claimed usage is ridiculous, they say they play games all day, LTE, Videos and still get like 5 hours or etc... Boggles my mind. My biggest battery hog I suspect is my VPN based AdGuard, maybe the vibration, but compared to gaming and etc, they sound so insignificant.

Yeah, that's more like my usage. Without my Watch, this may be the case. I don't use NFC. Thanks for sharing your experiences.

3 hours SOT is not normal for unrooted stock. I would suggest downloading GSam Battery Monitor and finding out what is hogging the battery. Note that you will need to manually enable the battery statistics permission with ADB for some reason, but after that it will work like normal.
The top two lines should be Android System and Kernel. If you see any non-system app in the vicinity, that is your likely culprit unless you can explain it with normal usage (for example, Firefox is at the top of the list on mine because I surf the web with it)
Alternately, if nothing odd shows up, you may have a bad battery.

This is a actually normal for USA SAMSUNG battery which is why no1 should get Galaxy S7 on USA carriers battery is even 100 maH smaller at 3500. Battery is always crap usa versions. And I am stuck in them nougat is bad for battery nothing you can do but downgrade to Android 6.0.1 with Odin. Best battery I can upload a vid for proof att Samsung S7 edge battery sucks and so will all USA carriers s8 never buying Samsung again GG. Switch phones best option iPhones have best battery but I hate them. I'd go for a phone with biggest mAh in specs and read reviews for battery. If downgrading doesn't work sorry for all Samsung lovers who read this it's just fact if you actually compare USA version to international. Battery on international is 92 ish hours not even close on USA version +1 sorry for my rant. Second best option I went to zero lemon and got a battery charging case that was like 10000 something maH and I never loose battery because I keep case on entire time makes phone weigh 4 pounds tho

Thank you for sharing your thoughts, bud, I think I would agree, this must be reality. An update for me, seems like getting rid of the VPN based Adblocker has helped battery. Last night, I finally got 4 hours SOT, but that was with the VPN app. Trying without it all day, let's see how it goes.
BTW, hands down, the best battery I have ever seen in the US is on the Huawei Mate 9, even on Nougat. The HUGE battery helps, but legitimately, I was getting 7 hours of SOT.
Thanks guys!
Got the attached SOT after turning off the VPN based ad blocker and using it as needed, rather than on the whole time... Is this closer to normal? ?
I only get 3-4hrs SOT but it is connected to my huawei watch and music is playing when it connects to my bluetooth fm transmitter in my car. I also usually have it plugged in while driving. The best battery life SOT I've seen is on the moto z play. My sister has that phone and she got almost 9hrs SOT. Usually gets at least 7. Someone got over 10.
