Hello everyone.
Recently I acquired a Cube U9GTV tablet. When it comes to value for money, it's quite okay. However, I think that something drains its battery.
This is my first tablet so obviously I have no idea what to expect, but I have a Samsung I9000 running 4.2.2 and compared to it, tablet's battery is out of the league. My phone can stay up to 3 days being idle, taking no more than 1% per hour (of course without wifi/3g/gps, just cell signal). When it comes to my tablet, it can hardly last a day without charging, eating 2-4% of battery per hour. No wifi, no synchronization, no location access.
Maybe I just expect too much, but I some other users of this device report that their device can stay alive up to 3 days, while being completely idle. Mine cannot make it to a day.
Things I have done so far:
Clean ROM install, no Google account, no Synchronization, no Wifi, no BT
Deleted Phone.apk, TelephonyProvider.apk, MMS.apk -> the Mobile network signal bar in Battery status changed from red to yellow, battery drain decreased a bit
Disabled Media Scanning by Rescan Media Root
Stopped Google services running in the background (but didn't touch the cached ones)
My tablet enters Deep Sleep with no issues. But I noticed that the battery drop rate is not a constant, it varies and it seems that sometimes it drains the 1% per hour, but then something happens and hops to 4%/h.
The thing that concerns me is the Mobile network signal, which is completely useless cause my tablet is only a Wifi version, and I do not use external 3G modems.
I am unable to see battery usage in Settings, it just says it's unavailable. So I got myself Better Battery Stats, made a test and screenshotted results (see Attachments).
Why does it show No or Unknown Signal and No data connection at 100%?
If you have any suggestions or tips, share them with me please.
Thank you in advance.
Bumpety bump.

Hi,
For those of you that have Battery Monitor Widget installed, what kind of average usage are you seeing with the phone idle, screen off?
On my old Desire it'd sit at something around low double digits, 10mA or so idle with the screen off...
On my new shiny SGSII it's at about 180mA odd, which may explain why I struggle to get a days usage out of it. I've tried different ROMs (stock rooted, lite'ning, currently on villain 2.4.2) and different modems (currently KG6) and have used Ti to freeze all of the samsung bloatware without any improvement...
What kinds of values are others seeing?
Thanks
Jon
in idle , i get average of 50-60mA .. but after 3,4 hours of idle , i can get it as low as 9-10mA .. running on sensation rom 1.4 .. in normal use , it will hike from 100+ma to 400mA ..
it's actually a bit higher than my last desire HD. which in idle can get as low as 4-5 mA .. i guess that's all depend on the kernel ..
seeing at your idle usage about 180mA, that's definitely have something wrong somewhere. gotta find what apps draining the battery
Just did a test while I was down the gym - with mobile data off, but streaming music to a bluetooth headset, it was down to 60-80mA. Turn it back on and it's gone back up again...
Gtalk is frozen, Latitude isn't signed in... Nothing obvious shows up in Better Battyer Stats.. Other than removing apps one by one, any bright ideas as to how to work out which is the culprit?
I think i read that HTC phones actuality give true mah battery rates where on the S2 it is only get`s estimated.
I fully charged it last night, and left it alone overnight. Perfect signal (local picocell about 10 ft away), pretty much everything disabled, all user apps, samsung stuff frozen - only google apps unfrozen. Background data disabled, bluetooth, gps, wifi off.
After a few minutes, after a short while at 60mA odd it sat idling at about 9mA pretty much all night - used about 8% overnight. I re-enabled background sync, now sat on my desk at work with a reasonable 3G signal it's sat at about 60mA.
Time to start unfreezing apps and see what's draining it!

It's installed - I get a lot of events/0 and suspend listed in process, and not that many wakelocks listed...
I've just frozen the samsung email client (exchange) and the associated processes, and my usage has dropped from 60-100mA at idle to under 20 - looks like this may be the culprit!
Going to try unfreezing it and seeing if it goes back up again...
I gave up trying to freeze / unfreeze stuff - too much hassle.
So - did a factory reset this morning, so back to a totally fresh villain install. I even removed my 32G sd card in case that was causing issues..
Disabled automatic app re-installing, and have been slowly setting things back up while watching the juice usage.
Currently with touchwiz and all of the samsung crap frozen, no widgets running, my 2 gmail accounts and exchange activesync configured, and it's idling at about 50-60mA.
It's going to be a pretty drawn out process working out what's causing the drain
The mediapad is my first tablet. I just bought a second hand one, and two things trouble me:
1) The RAM in active processes is displayed as 512, should it not be 1GB?
2) battery life seems too low, something along the lines of 3 hours of mainly google play use. I have high resolution set, active wifi, had no sim inserted, though plane mode was not activated.
A lot of devices display less memory than you think they should, it's ok don't worry.
Yes the battery does not last very long...

mediapad battery life
If you go to settings/applications/running services you should see bar at the bottom of the screen indicating free and used ram. Mine is standing at 191MB used and 434MB free at the moment.
I was going to ask about battery life myself, so here is a question for all other mediapad users: How much "screen on" time do you get per charge?
No matter what I do, I can't even get close to 6 hours that are specified.
The best I got was 5:15, and that was offline (wifi and 3G), brightness on minimum (bedtime reading), JuiceDefender on.
Only apps I was using were Adobe Reader, ComicRack and Amazon Kindle.
If I use Opera, Facebook, YouTube, StumbleUpon, News360, I get about 4 hours of "screen on" time.
When I look at battery usage breakdown in settings, display or wifi are never at the top. Usually there is AndroidOS or Android System, followed by some of the apps I was using.
If I play GTA3 (ver1.3 works great btw), it drains about 20% per 15 minutes of playtime.
On occasion it happens that battery drains at usual rate to about 15%, and then the shutdown countdown begins, as battery drops from ~15% to zero instantly.
Also, sometimes when it drops to 20% goes back to 30%, then from 10% goes back to 20% and from there drains to zero normally. It drives me crazy as I'm never sure how much juice I have left.
Tried to use Battery Calibrator app, but still the problem still persists. Can't root, still have year of warranty left.
Do you guys have any similar issues, how do you cope? And don't forget to tell us your "screen on" times and typical usage.
Thanks!
I know this might be somewhat of a gravedig but I really need to correct things a bit...
With WiFi on, screen brightness down and constant screen on + surfing / reading I was able to squeeze out 7 hours and 10 minutes out of the battery, starting at 100%...
The battery really is awesome! Just make sure to turn off things you dont need (Bluetooth, GPS, 3G / Mobile Data, Screen Brightness).
I'm surprised, in a positive way.
The only problem I got is with the touchscreen shaking and at times not taking my taps.
I am currently using a Galaxy S3 SCH-I535, stock, unrooted, and have noticed decreased battery performance over-time. I have already viewed many similar threads to try and pinpoint particular issues (wakelocks, troublesome apps, etc.). I was hoping for some perspective whether my battery life is up to snuff.
I have seen many describe their phone life with ~3+ hours of screen time with moderate usage. I use my phone intermittently throughout the work day to chat (Text messages, Hangouts), check e-mail, and band rowse the internet. I do not use Wi-fi, aside from when I am home in the morning or at night, and make sure to turn it off if not connected to a network. I have sync turned on, but the only accounts I have syncing are Google Now and Gmail. I have location services/GPS/Bluetooth turned off, and run in Power Saving mode with brightness at ~50% and haptic feedback turned on. My reception is subpar, usually about 2 bars and spotty 4g connections at work. I do not stream music, play games, or watch videos during typical use. No facebook, weather apps, etc. that can be culprits some times. At best, with the usage habits described, it is typical that I get 2 hours screen time over a single day (~16 hrs) before I get in the single digit batter %.
I've attached some screen shots I took of battery stats at ~50% drained (I didn't get a screen grab for it but at that battery % I had probably 1:05 to 1:15 hours of screen time). I just started using Wakelock Detector to find any problem apps - after tweaking some apps last week this has been pretty typical behavior. I have even swapped batteries with my wife's S3 to see if it was a battery problem, but did not notice a difference.
Any feedback would be greatly appreciated. Are my expectations for battery life too high? Is this typical, or am I running lower than I should be?
I just realized I selected the wrong forum and have opened the thread in the Verizon Galaxy S3 forum...can a mod please delete this thread? Sorry for the confusion.
I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??

I have read the other battery problem posts and haven't seen that anyone has reported similar problem to mine...
Typically I have a full day of use with my Gear S (BT on; wifi, mobile and gps off) and come home with about 45-60% battery.
However, about once a week I have had it suddenly chime with the low battery alert after only 2-3 hours, same settings!
What is going on? Notifications from Google Now are kind-of excessive (once an hour), but don't have any special apps installed except Watch Styler and Zooper wearable widgets. Anyone else with random poor battery performance?

Mine has better battery life on some days than others. I haven't had it that long but all of my settings remain the same, but its definitely not as drastic of a difference.
Hmmm, wish it was that way for me. I'm sure one of apps is hanging in the background after being triggered or opened, though not sure which one or what else it could be. :-/
Same Problem
When I am work, my battery dies in less than 8 hours even with VERY little use. When I am away from work (weekends, etc.), my battery will go all day with phone calls and texts and even GPS usage. I'm wondering if it's related to the Wi-Fi or cell signal I get in my office. I have Wi-Fi turned off on the watch but it made no difference. Something must be "active" to cause it to drain that fast! Less than 8 hours with very minimal use.....WTF??????

Is your mobile network on the watch set to auto or always On? Maybe you can try turning it off and see if it helps save battery life..
I agree with the post about turning your cellular data off as the watch will constantly try to get information and if it is a weak signal it causes battery drain.
Well ever since i switched the cellular data to edge my battery consumption it reduced to almost blue tooth levels...about 3-4 % per hour [emoji2] i can can have it remotely connected all day with out any problems.

I've notice that some clock styles are huge battery drainers and mobile data on, eats up your battery like crazy, also motion. BATTERY IS THE ONLY BIG DISAPPOINTMENT THIS WATCH HAS
For me the trick was to never turn my watch off! I now put it in airplane mode overnight and deselect in the morning. I'm still not sure what causes my problem, but powering up the watch would result in about 20% battery loss per hour. I think it is a software loop running in the background after the watch engages in system update check. Now I get through the day with about 50% battery remaining and can use motions and even always-on.
