[Q] Standby Battery life woes - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

So Does anyone get good standby battery? Lately, not using it, it only lasts about 2-3 days. My wife's iPad at the same point in time has about 80% charge left if it isn't used.
Thinking about switching back to Apple on the tablets for just this reason.

DId you see what causes such huge draining
Hi, did you check what is causing this huge draining? My tablet is fine, taking just 2-3% overnight.

My P600 drops 5-10% over a 24 hour period, but only drops 2-3% if airplane mode is on.

Probably you installed an app that causing wake lock. There are a lot of theads about wake lock, but for you to know is some background process that don't allow your device to enter in deep sleep. Unfortunaly, android is like that, if you install a bad app you going to have issues.

Yeah maybe, but with KitKat and no root, ferreting out problems is much harder. Seemed to be mostly fine before the last two updates I got.

Thats crazy ... Android OS should not be anywhere near that high a percentage. Have you tried reatrting your tablet a few times if not I'd say factory reset and see what happens. I must say this Tablet has had A LOT of people complaining about battery issues - seems like a product fault somewhere. Fortunatly mine is still gojng strong hopefully that doesnt change.

Yeah, it restarts itself when I pick it up and the battery was completely drained. Yesterday I had 6minutes screen on time, and was dead within 2 days of unplugging it. Bought an iPad for Christmas. Can't decide what to do here. Android seems to always have battery issues with the solution being "Factory Reset it". Annoys the heck out of me.

So, after a data wipe. Minimally installed and syncing apps, the 2 day drain is gone, replaced by losing about 3-4% at night. Now decisions. The deal was I was suppose to sell my Android tab here, and buy an iPad due to battery frustration woes. Well, it was the deal with my wife. Now I am thinking of just keeping both of them. Wonder how long I can hide it. iPad still destroys the Note 10.1 2014 on battery life....but there are a few Android things I want, e.g. Stylus, Share menu, that I believe Apple or app developers on iPad will fix soon.

Standby Battery Life?

I know there are threads regarding battery life out there, but most are all about usage and screen on time. My Note seems to be on par or at least close as far as screen on time. However, I'm just curious as to what all of you are experiencing as far as standby time. I've gone through the battery life guide and turned off most features I don't use, but the standby time still seems pretty lame. From a full charge, its been 3d 5h on battery with zero screen on time other than checking the battery stats right now, and it's down to 9%. Android OS consumed 57% and Google Play Services 33%.
I know I'm comparing Apple and Oranges here, but my 4th gen iPad I have for work hardly drains at all without use. After a week of standby, the iPad will only drop about 5-10%. I feel like this tablet should be capable of the same, and possibly will be after I root and find a good rom (also don't like to see any Apple product out-perform any android based product). Am I alone here?
Basic setup: Stock Rom (not rooted), Nova Launcher (prime), GPS off, Bluetooth off, reading mode off, multi-window off, screen mirroring off, s pen detection off, all samsung crap off (air view, etc), and others. Basically the only thing on is wifi.
I only have wifi off during standby and it drops 1-2% every 12 hours
You might have a tough time getting people to compare their standby time with yours... most people on this forum either use their tablet for work and if not are too in love with their baby to let it sit there untouched for days on end When I couldn't use mine for 12 hours, it dropped about 3% with WiFi and GPS on

Yeah it is too hard to not touch it for days on end to test this. Turning off wifi while in sleep mode will help a lot. Go to the Connections tab in settings and hit the hardware menu key, then choose Advanced, and change Keep wifi on during sleep to never. That has helped me a ton. Right now mine is at 2d 7h 40m uptime with 4h screen time and it's at 32%. Even with that setting on, my iPad mini still gets better battery life. I have left it sitting for 2 days before without touching it and found it sitting at 92% battery life with wifi always on. My guess is it's something to do with the OS and iOS is just more efficient. That's why even with weaker hardware it can still outperform android tablets.
Also I'm still running a lot of the things you have turned off. You might want to also try Greenify. It has a non root working mode now, but works best in root. You can also try Wakelock Detector to see what apps are waking your cpu, so you can see what to Greenify. If you root you can also try an app to freeze apps as well like Titanium Backup and Rom Toolbox.
yeah, forgot about greenify. you have to be rooted though an need either the donation version to greenify play services(that's the battery killer) or use titanium to make it a user app to greenify with the free version. it's sad that google is the worst culprit with battery drain on all my devices.
I get 1-2% battery drop every 24hrs of standby. WiFi must be off, it not hard to just pull notification bar down and touch the wifi section off whenever you think you wont use the tablet for a while - takes like 2 seconds.

I have yet to try my battery life with wifi off, so I think that'll be next. I really don't need it connected while the screen is off, so I'll change that setting first.
I figured it might be difficult to get a good response for this question because I too have a hard time putting the thing down. Was just traveling for work and had it in my bag those 3 and noticed the battery drop. I appreciate all the suggestions and welcome any future ones. In the mean time, I'll be experimenting as well and report back if I find anything causing the drop.

Battery Sudden Drops

Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?
Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.
So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...
How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.
I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.
Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.
Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.
I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag
I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!
Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.
Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.
I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten
Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.
Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.

[BATTERY] Significant Drop in Battery While Idle On Android 5.0 and 5.0.1

Hey All,
I'm just wondering if anybody else is experiencing this issue. Since upgrading to Lollipop, my Nexus 7 battery loses FAR MORE battery while idle than when I was on KitKat. I was hoping that 5.0.1 would fix this issue, but I seem to be having the same problem. It's entirely unacceptable that I go to sleep with 31% battery, and wake up with the tablet DEAD. I have kept a close eye on Running Applications, and have made sure to close them all before leaving the tablet alone. So much for Project Volta...
Anybody else having a similar experience?
Thanks,
Collin
I'm actually seeing the opposite. On Saturday I had mine plugged in and charged to 100%. I took it off the charger and threw it in my bag, where it sat for about 7-8 hours (drove about 3-4 hours and then it was in my car for a few at a restaurant before bringing it into the hotel), wifi and bluetooth on, but disconnected the entire time. It is in a Poetic smart flip cover so screen was off the entire time.
When I got into the hotel it was still at 100%. Used it for a bit that evening, and again the next day before driving home, and finally used it some more at home, but still had over 50% left before bed.
My battery life is also suspect.

I was one of the Android L developer preview early adopters and the only thing that kept me from switching back to cyanogenmod was the fact that on the last developer preview whenever Flo said the battery was low I was so surprised I felt cheated. The battery life was so good every time it gave me low battery life notification I was shocked because I had forgotten that this thing even has a battery and needs to be charged.
I don't know if this is psychosomatic or what, but it sure doesn't feel like this on 5.0 or 5.01.
Full disclosure: it's reporting 6h 22m of screen on time with 5 hours of battery life left to go, but it sure doesn't feel that way.
The battery settings used to tell me ridiculous things like 6 days of charge left. It doesn't do that anymore.
Right now I'm in the process of discharging it all the way to death. We'll see if that makes a difference.

Yes I'm having this issue. After upgrading via ota my tablet is dead in less than two days from battery drain

@collin5022
OTA, OTA with factory reset or img flashing?
Because if you upgrade yours N7 via OTA without factory reset that (and various others) bugs are possible.
My N7 doesnt show idle battery drain (img flashed) or any other bug, so far im very satisfied with 5.0/5.0.1 android.
First off don't close applications this is not Microsoft windows, second use CPUspy and a wakelock detector to see what is preventing your tablet from deep sleeping, third use a system disable app like auto run manager to disable any services necessary, fourth.....profit
^Agreed except for the last part.
Those apps that stop/freeze other apps like the one you mentioned, greenify, anything like that are all bull**** that cause more problems than they claim to fix, IMO.
Flash the factory image. Don't take the ota or keep data when its a major new release.
Battery life is awesome on 5.0.1 never been better.
Android 5.0.1
Default OTA 5.0.1 brings NFC active! When i turned it off, the battery became significantly more durable!
Just try it!

If you disable the 3 common service locks keeping the device from sleeping there have been no problems so far for me on n5 or n7
And yes greenify is worthless autorun manager not so much
^Yeah I see what you're saying. But still I don't like interfering with system apps, well like play services I mean. That can cause problems and battery drain. It really depends on how you use the tablet.
Edit: And obviously like said don't be closing running/cached apps. This isn't Windows 98.

LG G4 - Pitiful battery life

Hello all,
I recently purchased a LG G4 Back In July , on Verizon, switching over from A Galaxy Note 3 (Tmobile). Honestly I really really like the phone, but I think the battery life is pitiful for a $700 dollar "Flagship" phone. I mean not once has it ever lasted the full day. I had to buy a spare battery kit, with 2 batteries, and days when im out from 6am to late at night, I go through 2 batteries, and have to put the 3rd one in. I mean , this is simply unacceptable for a phone like this.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.
I am hoping there is a way to fix these 2 issues, mainly the battery issue though because it is awful in my opinion. Is there any tweaks or fixes for these issues?
You've barely given any relevant information other than how unhappy you are with the device, so I would suggest that you elaborate on that.
You could inform us if you're a heavy/light user, if you keep NFC, LTE, Bluetooth, Syncing, Wi-Fi, on during the whole day or maybe if you are used to 100% brightness display. Maybe you should check in your settings what is draining your battery and provide us the info.
I'm having a pretty good experience with the phone so far. It surely lasts a whole day with 3:30 to 4h SoT. I don't even need/have a spare battery.

One person having an issue doesn't mean it's not a great camera. You'll find it's likely still the best flagship camera of any OEM.
Battery use is so dependent on which apps you run, which mods you have, how often the screen is on, what brightness, signal strength, wifi, bluetooth, etc etc etc...
I came from a galaxy s3 and reckon the battery on g4 is awesome. I use it solidly on internet for 2 hrs a day (to and from work), check messages etc through the day, usually internet at lunch. And then evening time check facebook etc over WiFi infront of telly.
I unplug at 6am and plug in around 11pm with around 3% left. I bought a 2nd battery and only needed to use it twice. It has to be how you're using it.

13 hours on battery for me today and still 71% left. Light usage but it does illustrate that the battery life can be excellent.

of course, you can get excellent battery life on every smartphone - just put it in aeroplane mode..
I get MAX 3h of SOT time on my G4 - this is with fixed brightness at 65% (at all times) and only wifi and 3g enabled (NFC, bluetooth and everything else is turned off all the time)
to be fair I have yet to own a smartphone that lasts me more than 4h SOT..
the thing that annoys me the most is the broken knock code used to unlock the phone - it works 20% of the time at best
its a completely broken feature LG has not properly addressed since launch of the device (I am on V10e software)

There have been numerous firmware updates since. Have you ever performed a full factory reset after getting those updates ?
If the answer is no, then this is one potential reason for poor battery life. What you could try is to clear the system cache in recovery. Note, i said system cache not apps cache. Idea here is when updates come in there could be conflicts and it causes the system to work harder. clearing system cache might help, if it does not then the only option is a factory reset and then a manual install.
not restore. You install apps in batches, monitor, then install more and so on. You can restore contacts etc. but apps themselves will have to be reinstalled. Sometimes apps go rogue and have to be reinstalled. Its hard to tell which app is causing the issue. Otherwise you could just reinstall whatever app that seems to be taking up more than it should be.

How do you access the net. How good is your signal. What are you doing when you access the net.

What types of shots are these. It can happen with portraits some times. It will focus on the background behind the person instead of the person and the face becomes softer and the background very sharp.
For this set focus little above the chest instead of the face. If they are wearing dark clothing this will cause other issues so focus on something else at equal distance that isn't dark.
Always check the shot at the pixel level soon after you took it. Rather than at the end of the day.

Just to clarify: I had everything turned on for those 13 hours - wifi/data/bluetooth/GPS. I also made 2 phone calls and did a bit of Chromecasting using the BT Sport app for a couple of hours. Or to put it another way, I didn't take any measures at all to preserve battery life.
I used to complain just like you're doing OP ( @dredmentia ) and fixed it all with a Zerolemon battery .
Is the phone bulky/no leather back/not easy to handle... , it sure is but if battery life is crucial then it gotta get fixed.
End my day anywhere between 7 to 13 hours of sot depending on WiFi or 4g and high CPU freqs, tried light usage and hit 3 days with 12 hours sot. Snap/insta/twit/fb/periscope/... Nothing kills this battery in a day.
When and if we get a kernel I'll move back to factory battery at least then I know I'm in control of how CPU works coz while optimizing the phone for wakelocks that's the only thing I have no control over...
As for now I'm just trying to burn thru this battery every day so I can charge it every night...
Last phone was a Z3 Sony and that really grabbed my attention with its battery life in stock form, almost too perfect, Almost.

Did someone seriously just ask me if I kept the brightness on the screen at 100%???? Obviously im not doing that, im not some idiot. I know the screen eats up most of the battery. I keep the brightness extremely low way under 50%, or on auto., The battery still last a short amount of time. Its not acceptable

Did someone seriously just ask me if I kept the brightness on the screen at 100%???? Obviously im not doing that, im not some idiot. I know the screen eats up most of the battery. I keep the brightness extremely low way under 50%, or on auto., The battery still last a short amount of time. Its not acceptable

Is every single Galaxy Tab Pro 8.4 DEFECTIVE?? Seriously I've had 3... sm-t320

I've had brand new and returb tab pro 8.4 and they always start losing track of the battery charge, screen flickering, random reboots.
I have a theory that this tablet can be damaged by other USB chargers .. Clearly tons are breaking based my experience as well as Samsungs reaction to the fact that I had these probkems.
Does anyone have one that works correctly? Im considering giving up on Samsung Support. No reason to chase down yet another 90 minute tablet.
Included pic of some battery stuff.. it's actually worse than the screenshot.
thx for your thoughts

Same problem here flickering the restart itself. Help guys...
I don't know about every single one being defective. I would think/hope not, and that there are some out there that work as intended. But I certainly couldn't say mine belongs to that (non-defective) group; as mine suffers the common battery charge issue. Between that issue, and the nearly complete and utter lack of OS updates; this is quite possibly going to be my last Samsung device.
Its always hard to tell how common defects are, from looking at web forums; since the tendency is for folks to complain only when there is an issue (leaving many instances where the devices run fine, and go unvoiced). But based on the numberous reports here, I'd have to say the number of defective Tab Pro 8.4 devices is "above average" at the very least.
Most problems you have with the Tab Pro's can be fixed by switching to CM12.1 or CM13. It may seem odd that we need a custom ROM for this, but at least it fixes many problems. If you have battery problems, check out the link in my signature. Many of us have solved most battery problems by reseating the battery.
The only defect here was battery life time. After re-seating it, no problems at all. No reboots, or locks, great battery life, charges on a breeze... all of these on stock Samsung ROM.
I won't talk about samsung policy of updates, bloatware or anything, but I'm very happy with this tab and its specs
Put CM13 on mine, it's rock solid.

I was able to send mine to samsung a week before the year warranty was up, i had been experiencing all those same issues. When they sent it back, the notes said they had replaced a defective motherboard and battery. Its worked great since then, going on 5 months now with not a single random reboot or battery errror (knock on wood).
Aside from hating Touchwiz, mediocre battery life, and no updates, mine has been trouble-free.
I'm now on CM13 with no problems. Battery life is still mediocre (about 5-6 hours SOT with dim screen reading / web surfing) compared to my 2013 Nexus 7 under MM (8-12 hours) but that's it.

Try reseating your battery, the 8.4 should definitely be able to get about 10 hours of SOT with reading and websurfing with low screen brightness.
My problem is gone. Last night i went to a repair man. I re solder it battery Terminal to motherboard. Now i don't experience any flickering and rebooting itself.
Issue is practically resolved. Most of this trouble comes from the battery cable not being correctly assembled to the motherboard.
Look for the thread that says, Reseating my battery did wonders for my Tab Pro, and there is the answer, apllied by many people, all with success
Mine's fine. But it was never stock from minutes after it came out of the box. I immediately installed TWRP, CM13, and SuperSU. Everything works as it should so far.

The thread on battery reseating had more to do with erratic charging than with battery life. In the event, I just enabled power saver and Greenify. I'm now getting about 10 hours SOT with fairly dim screen for reading or streaming NetFlix, so I'm really a happy camper. No problems with CM13
I own two of these tablets and they have been great for the most part, the only issues I have are that it lacks OS updates (I really want to be able to have 6.0 and Samsung Kids Mode at the same time) and that one of those tablets has odd behavior with the SD card when in Kids mode.
