I have had my 701 for almost two years, and it has a been a great tablet for the most part. I have had one issue, however, and that is terrible battery life. I rooted the tablet back in January and put a Lollipop 5.0 rom on it from this forum. Back in the beginning of August, I put the Zombie-pop 5.1.1 rom it. It has run smoothly on both roms, but I noticed that the battery runs down very quickly. It has done this since January when I first rooted the tablet. When I installed both roms, I wiped everything and started from scratch. I keep the screen brightness at about 30%, WIFI on, bluetooth off, location settings on battery saving mode (so GPS is off), am using the ondemand governor (Have tried others with no change), cfg I/O scheduler, etc. To give you an example of what is happening, last night I charged the tablet to 100%. This morning, I played a game called Astrowings2 for about 30-40 minutes. When I closed the game, the battery was at 63%! I can play this game on other tablets I own and the battery may run down about 10%. Is anybody else having similar experiences with the 701?
I will guess by the lack of responses that nobody else is having this issue. Maybe the battery itself in my tablet is slowly giving up the ghost. That is the only conclusion I can come to!

You are not alone with the battery problem. That is why I installed Zombi-pop in late September. At first all was great and power use was fantastic. Now it suddenly drains unexpectedly and it goes off entirely, so I never catch the event. I wish I could figure out what app is the culprit, but no luck so far.
I don't play games.
What is an acceptable battery drain?
Hello Guys,
Like so many, I am having issues with the battery life on my TFT701T. I am digging into it, using BBS. Over 12h, it goes into Awake Screen Off only for a few minutes (6mn) but the battery is gone from 100% down to 35% (both batteries, dock is attached), that makes a 6%/h drain.
What are your numbers? My tablet was sent back to Asus back in January, for a complete batteries replacement, and was then working fine. This issue appeared again lately (August, September), tried everything I read here, but I can't get better...
Thanks for your help

Hey Guys, I've posted in other conversations about bad battery life with blitzkrieg and it seems pretty split down the middle between those who experience good battery life and those who don't. I did follow the advice and wait several days after I re-flashed blitz and my battery has yet to level out. I keep background data off at night when I go to bed, I went to bed with 93% battery left and woke up 7 hours later with a 23% battery life - while the phone was at rest.
I also have a problem about once every two days my phone will freeze up and restart. When it happens it just gets froze on screen and the whole phone vibrates for 20-30 seconds and then restarts.
Has anyone experiences these problems and found a solution to them? Should I change my settings at all?
I really don't want to get an extended battery but with the life my phone is currently getting I don't see much more of an option.
Thanks guys,
The phone freeze/reboot is a known issue with no known resolution. Before I dropped my last phone it had that problem consistently from stock v4 through every variant of the ota updates, revolt roms, gingervolt roms, kennels, scripts, no scripts, blah blah etc.
Now, however, I picked up a second Revo and have run it through gb and flashed gv 1.3, blitz 2.1 and various scripts and tweaks virtually mirroring my old device. I did that Monday morning and haven't had a single instance yet! These guys here do awesome work..
As for the battery draining, I haven't put my extended battery back on this phone yet because I was curious how the stock would perform with these mods. For the first couple days I was discharging at an even 10% an hour. Yesterday and today its dropped to 7.5%. Why? No damn idea. But I can live with that.
So, nothing terribly helpful here but just a disclaimer that your mileage may vary and a nod to the devs here doing kickass work. Good enough that I actively went looking for another Revo instead of fussing with a second line upgrade. That speaks volumes.
Oh yeah I'm not dissing the devs at all they're great!
The revo is a strange device all the reboots due to GPS and airplane mode I'm sure is a hardware fault because every revo I've had has done it and I'm on my third. I love blitz and can't live without my overclock lol I'm just wondering if there's special settings or CPU governors I'm not using that would help.

I've used CPU Master and am on ROM toolbox now. Can't say I've seen a significant difference between the two as far as battery goes. I've used both ondemand and smoothass, same deal.
I did have some luck limiting reboots on my first by bumping up the min to 768 but haven't needed to bother on this phone so its 2 something. No extra settings or anything. : )
Guess it's just the screwy differences in hardware that make some a better build quality than others. Well I said I wouldn't do it, but I lied...
I'm restoring to my GV 1.3 pre-blitz image as I type this. Guess I like battery over performance, we'll see...I may be back to blitz.
Can somebody explain the difference between ondemand and smoothass. I still don't understand them that well. Thanks!
I didn't read the whole thread but seeing profiles for the kernel helps a lot like when my screen is off my phone is set to minimum on the min and max which sometimes causes lag turning on but once the screen comes on it's up and running fine. At that level if I keep the screen off it takes nearly an hour to drop a percent.

Perhaps this is not the best reference but here is one about charging your Lion battery:
This link won't paste:
[URL="http://dottech.org/tipsntricks/17705/tip-condition-your-new-cell-phones-battery-to-make-it-last-longer-but-be-sure-to-condition-it-properly/[/URL]
It points out two possible issue:
1) over discharge (perhaps our meters account for this,
2) getting the battery hot, my phone does warm up setting on the charger, sounds like the usb port charging might be better for the battery?
Is anyone else having issues with the battery life on their Gear Live lately? I'd say in the past 2 weeks or so the battery life has gotten absolutely awful with no reason at all. This is seriously as bad as the original Galaxy Gear at this point. When I first got my Gear Live back in June the battery would last all day easily, and I'd usually have at least 30% left at the end of the night when I stuck it on the charging cradle. Now when I get home from work it's almost always at 20%. I don't have any apps or custom watch faces on it because they all suck right now (since the SDK isn't available yet), and haven't changed my usage patterns with the watch at all since I got it. I've done factory resets, used it with other phones just to see if it's something weird with my phone, etc. Nothing helps. Anyone else having these issues suddenly? Thanks.
Kind of bad today 33% ..... may not make it home

It seems to be getting worse each day. At this point I've double checked to make sure no apps are installed on the watch and just did another factory reset of it. We'll see how it is today. This is horrible, if it doesn't improve this thing is getting sold.
It was just a bad day.
I may start turning the screen off when I am out in the sun.
Wish there was or I knew how to quickly toggle the screen on/off

Yep, would be cool if pulling down to mute also turned the screen off unless turned on manually or by gesture.
I'm having sudden battery issues as well since yesterday. Took of the charger this morning at 8 am, by 10:20 only 75%, did reset and it changed to 49%, now at 12:45 I only have 12% left. Almost zero notifications, battery stat app shows no app use. Very confused from this.

I can't say absolutely awful, but it suddenly lasts less than half the time it usually did. I used to go two days with around 21% left when putting it to charge, since around the 24th of December, suddenly last barely a day. I find it really weird, as I am using everything the same as before. The only thing I can think of is the watch being on Android L, and the phone on 4.4.4 KitKat. This is just a theory as I have no Android L phone to test this with, that the 2 versions of Android use the Bluetooth differently and thus create a battery leak. I am not sure, I will have to wait until my Moto G gets Android L.
I am returning my watch to Google because since 2 days ago my battery dies at 4pm when it originally lasted all day and when I went to bed I still have anywhere from 20-40% left. Also my charging cradle broke and won't stick to the watch. Had to use rubber bands to charge it. I wish I hadn't bought the Samsung Gear Live because it is a piece a junk... The Asus Zen watch costs the same and is much better quality....

I thought I was alone
Mine went from going around 2 days to now about 6 hours. I
I've nuked it and my phone to no avail.
The only think that changed was I upgraded to Lolly Pop. Would love a fix for this
What a scam. If this is how they treat early adopters I'm not going to buy another
I just bought a used gear live, and my battery was terrible with almost nothing but a watch face really added. I went to the google fit app on the watch and scrolled all the way to settings and disabled it and it seems much improved already! I think the step tracking is killing the battery somehow.
So Today I had the wifi on the watch turned off and also had Google Fit turned off. Got a good bit of notifications for texts and such and used voice to replay to the majority of them. With always on screen turned on half the day and tilt to wake motion turned off all day it is at 50% and has been on about 14 hours and says it still has 14 hours left. I am pretty happy with that!
I was having battery issues at well. It got so bad that my watch wouldn't last from 8am until about 2pm. Finally I just stopped wearing it for a few weeks. Picked it up again a week or so ago and got the update. Since then battery life is back to what is expected. However, I haven't added my wifi hot spots yet.
Try the app SWapp True Dark. It allows you to lower your screen's brightness more than what is offered by default. I now get 24 hours out of my watch on a single charge and that is WITH the screen set to "always on"!

Should also remember that Li ion batteries typically have a charge life of 500 cycles or 18 months before degrading quite a bit. Some of you with older ones will start to have batteries go.
Hey everyone!
I got my Note5 near launch day. I love everything about it, except the battery life.
Basically, I am not satisfied. I barely make it through the day with moderate usage. The crux of my problem is idle/standby battery drain.
This has been a problem for me ever since I got my Note5 and even for some of my old phones (M8 on Lollipop).
The Issue: I'm fine with how the battery drains when I'm actively using it. I'm not going to go into much detail about that, but I'm satisfied with how fast I seem to be killing the battery while using it. The part I'm not satisfied with is how much the battery drains when I'm not using the phone. Obviously, this must be an issue with wakelocks. When you look at the screenshot below for Android OS, it is always wake for more than 2.5+ hours in a 15 hour usage period. Now, I'm not sure if that's normal anymore. I don't remember how it was on KK, nor do I know if that's what everyone else is getting.
The Issues Cont: So yeah I have massive idle drain. (I estimated that I get about 1.5-1.6% battery drain per hour. I charged my phone up to 100% and let it sit idle overnight for a span of about 8 hours or so. It went from 100 to 91 during that time). What this means for me is that, I can use my phone less and less because while it sits in my phone, it dies quickly! On GSam, it shows that my battery discharged 38% while the screen was off! Again, I don't know if this is 'normal'. What is everyone else getting?
What I tried: I tried factory resetting. Nope. I tried reflashing the firmware, factory resetting. Nope. I booted into safe mode and left it idle overnight. Still dropped to about 92% or so, IIRC. I actually had the GS6 Edge before the Note5, but I returned it because of the ****ty battery life. Then I inserted my S-pen backward and broke the sensor in the Note5, so I got a replacement. For each instance, I always got crappy battery life. So I am doubting that this is a hardware issue. I tried minimizing the apps installed so minimize wakelocks, but it didn't seem to help.
What I want: Honestly, I just want to be able to use my phone and have it not drain so much while it's in my pocket or on the desk. I want to be able to go into a lecture for a few hours and come out with maybe 1% drain, not 3% or 4%. And I want to do this without rooting. I don't want to trip Knox, and I'm tired of rooting and spending hours tinkering with my phone to get decent battery life.
Attachments: I uploaded screenshots of almost everything I thought would be pertinent. Please have a look and hopefully we can compare results and figure out whether this is normal for a Note5 or not!

I reckom its something you are downloading is doing it. Add one app at a time and see what it does.

Yes there is something keeping your device awake. Rogue app. First guess would be that Facebook messenger app. Look in settings for your running applications, try to limit those to ones you absolutely need using package disabler. If you don't know what's OK to disable, read through the debloating guidelines thread.

Never let Facebook or Games run in the background and MOST IMPORTANTLY disable location services completely. Keep it on a toggle and turn it off until you need it. Always keep it off or Google will ping your location once every minute. It literally halves battery life.

I don't have the Official Facebook app installed.. And I almost always keep location services off, but the battery still drains as it does..
Use the smart manager app to stop certain apps from running in background and restrict background data for apps that don't need it in the mobile data settings.

My battery is amazing and I can say this as I am a battery guru and have spent countless hours trying to squeeze all the juice out of my devices, which includes eliminating wake locks. If you had root you could figure it out, without root you'll have to start un installing apps 1 at a time until it get's better. Also check your exchange accounts.
I assure you something is wrong as my battery life is the best of any phone I've had.

This probably won't be helpful at all as it is a complete shot in the dark, but perhaps you have an app that is trying to get your location continually since you have it off? Maybe try leaving location on. I never turn it off and I've been getting very good battery life on my T-mobile Note 5.

My device is unrooted
Everything was going great until the newest update that came last week. Since this my battery life has gone down hill fast. I feel like I'm back on my G1.
I have two questions is anyone else having this issue at all?
My other question is all my previous phones have had SD card spots so when I reset myphone all my pictures are stored there. If I reset myphone do I lose all my pictures?
Battery life has been good for me on that build and the recent fi build as well. Do you have a secondary battery meter like better battery stats? There is no sd card in the phone so yes that would be lost.
of course you can check why your battery times have dropped.. like maybe a stuck process or a certain app draining battery. im nearly 100% sure its not because of the update, but it can be user related. your signal quality could be worse as well, which will also drain battery faster.

When I feel my phone getting hot or I notice the drain is going on I turn off my phone let it set to cool down or I just straight up restart it.
I live a pretty routine based life, Work, Church, Gym, Home.... So my signal life hasn't changed. My usage hasn't gone up or down....but my battery has since that update.
I do have battery apps to keep an eye on things. Display is number (of course) and number 2 which isn't normal is Android OS.

well, what ive found out iver the years that im with android is that battery apps are pointless, and end up using your battery. just check you regular battery usage/stats. nobody uses their phones the exact same way every single time, its impossible. and when you are out, walking around, or driving, your signal quality will change, constantly. and apps, many times they will get a process stuck, and drain much more battery than normal. and then there is google play services, that will occasionally drain lits of battery, especially when its updating itself. in reality, there are numerous other reasons, besides the update, that will make you battery drain quicker. too numerous to list, lol.

my battery also has been going deep underground after last security update! nothing changed in the usage or the number of apps that i keep installed, so the suspect that the drain depends on the update in my opinion is becoming more and more real.
i also keep checking battery's stats and there isn't any anomaly or discrepancy compared to pre-update's stats.
I am in the same boat. I was using about 2-3 percent an hour before the security patch. But since the patch dropped I've been averaging about 10 percent an hour. I have to recharge at least once in the middle of the day. None of my apps changed.
Same here, noticeable difference in battery performance since last weeks update. Only change to apps is I am now using Google fit since last week, thought it was that but battery stats say otherwise.

So last night I backed up all my pictures on my computer and the cloud. Tonight I will reset my phone before bed Ill have a better idea of what it will do tomorrow. It kinda stinks because I have this zooper/launchy/popup widget masterpiece going on my homescreen
Ill report back....
I have noticed the same issue since the OTA patch. Reminded me of my old Galaxy S where it would not go into deep sleep after being unplugged at a full charge without a reboot. I've gone without a reboot and with rebooting since the update and my phone is much better off after a reboot. About 7% per hour lost without compared to about 3-4% per hour lost with a reboot. Pretty consistent usage on a daily basis. Just my personal observation. I'm on AT&T though.
I got better battery life after the update... But then it went back to normal. I was being about 30 to 45 minutes extra SOT but now I'm back to my average times of 4-4:15 hours

Take this for what it is.... I wake up at 545 grab my phone since the update by the time I get to work 7am it would be 96 or below.... I reset my phone last night and the phone seems back to normal at 99%-98%when I sit at my desk..... All apps reloaded and working before bed.....
My N6 is worse off for battery too after OTA update of last week. Seems like Google Services has just gotten a lot more aggressive doing what it is supposed to be doing. I hope Marshmallow will fix this.

Hello.
I'm having trouble with the newly replaced battery on my rooted Xperia Z1 (with android 5.1.1).
2 months ago i replaced the battery because the old one overheated. The new battery has been fine untill a few days ago when it told me all day that it had 50% left. I found that weird so I didn't charge it to let it run out of battery so I could charge it to 100% and recalibrate it.
After the phone suddenly blacked out the battery wouldn't charge any more, so I took it out and messured it's voltage to be around 2.5. So I jumpstarted the battery back to 3.5 V and was able to make it charge again. Even though the battery functions like "normal", it still says 50% all the time with few exceptions which does look to be the correct battery level. The power management app disappears from settings whenever the battery shows 50% and reappears when it shows the correct level.
The battery indicator shows the correct percentage when charging, but not otherwise.
My theory is that there is something wrong with the software regarding the battery management and that it let the battery use too much of it's voltage. I've seen people with similar problems (50% battery indicator and disappearing power management), but the only solution there was to replace the battery. It doesn't seem that likely because of the software being buggy and the battery is only 2 months old.
Here's some screenshots of the weird behavior:
imgur.com/SXSMdzi

(Couldn't include image because I am a new user)
As I were writing this, it began discharging while hooked up to a charger. Seems to be a bit unstable.
Would appreciate all and any help
Hello!
I also got similar issues. I've read and try anything to find what happened with my Z1.
First, in my experience, some says (on internet) it's Android problem called Sudden Battery Drain Syndrome. I've tried apps like repair battery etc. and calibrator to fix it. Still the same the battery drain badly.
Second, so I am continuing my investigation on internet. I read from xperia care etc and I found that android Lolipop (5.1.1) terribly sucks for Xperia Z1. Many Z1 users confirmed this. Not just the battery problem, there are bugs also, like touchscreen, screen flickering etc.
Third, after knowing this and read like 2 hours to find the solution, I found in this forum that it's better to downgrading the android version back to KitKat or JellyBean. So I installed JellyBean firmware. Just now finished. I hope it'll be good again. I'll inform you.
NB: Factory reset also won't work
Hello, nice to get some response on this thread.

I tried battery repairs, calibrators and so on. Did not do anything for me. After reading up on Sudden Battery Drain Syndrome, I'm inclined to say that it doesn't seem all that similar to my problem.

That is interesting to know. I have experienced alot of those problems. I was thinking about upgrading to a custom unofficial Android 7 for xperia z1, hearing this might be the thing that makes me do it. It's always such a hassle to download apps and set up from a new install, so I've put it off for a while.
Some days after starting this thread, I ordered a new battery. The old one started to do the same thing. Seemed like I could jumpstart it again, but I don't see the point in doing that every other day.
The new battery has been working great for almost 3 weeks now. I still have the Lolipop problems you mentioned, but the phone works as it is supposed to. It acts up from time to time, but I suspect that being because I use Greenify and CPU tuner to make the battery last longer. I might be upgrading to Android 7 and if that fails, I might downgrade.
I'm hoping I was unlucky with the last battery because it lasted so short and that the problem was only related to the battery. I will post updates here if the new battery also suffers.
