Damn impressive battery life on stock 4.4.4! - Xperia Tablet Z General

Let the topic title and the pictures tell the whole story about how insanely good battery life we can get out of the Tablet Z if everything is correctly adjusted and with a proper set-up!

And this..
Pure amazing results!

I got to agree with you
quite impressive

Yes its nice. But all Sony Devices since Z series are very good. Sony have done a good Job.

It's true but when moderate use with stamina. Classic "stress" cycle with gaming, Lte, or some draining apps can eat juice instantly. Few hours and it's dead. Lte is main problem. No simcard = no drain. Before tabZ I had Asus tf300tg and battery was much better (due to lower connection type) . This one is tricky. After all I'm happy that when I put it away it can stay for week. but when it is used, battery goes quickly down.

well, lte may be the cause, but usually if signal is strong it's not. Finetuning kernel clocks, and app wakelocks, especially messenger and google ones, will make battery life much more longer.

Then fine tune your kernel parameters so it utilizes more cores and AT a lower clock speed than core core and ramping up to max clock. More efficent hotplugging is the **** for battery savings!

As far as I know - the Xperia Tablet Z with LTE / WCDMA / GSM enabled functionality has the same SOC and mobile circuits as the twin brother Xperia Z - use Better Battery Stats-app and see IF you've some nasty MSM_HSIC_HOST wakelocks / issues appearing?

The battery on this tab is amazing, but I have the Z phone and the battery health deteriorated very quickly, so I'm hoping the same doesn't happen here.

[DISCUSSION] Battery life with overclocking is epic!

Only had the phone for two days so this should improve even more:
overclocking to 1.4ghz, under clocking when screen off to 0.3. 9 hours screen off, didn't lose a percent, still 100 on desire Z. EPIC!
thats good to hear ! Cant wait till i get my hands on it! damnit ! 5 or more days togo
Did you have any other functions enabled? 3G/WiFi? Sync'ing with FB or Twitter apps? Anything like that?

how many hours can you get out of it when you are using it throughout the day, e.g. email, internet browsing, twitter, bit of music and phone calls? using data and wifi?. Im on my 5th day and averaging about 14 hours, hoping that the battery hasnt settled yet, otherwise my hope is for the NAND being hacked and roms for optimal performance!
Do you actually get more real-life performance out of the overclocking (snappier menus, faster app launching), or the only place where it shows is the benchmark? Is Sense faster, or is the difference not visible (0.8 vs 1.4)?
On the other hand, underclocking could be really useful to preserve battery. But doesn't the processor underclock on its own when in standby (by design), do we need to use 3rd party apps?

contrary to what you should expect,
overclocking this SoC just hightens the clock's max roof from 800MHz to 1GHz, 1.2 or 1.4GHz, not the "permamnt" MHz count,
because it auto-fluctuates and adapt depending on usage
AND with the SetCPU app (which I assume JupiterDroid is using),
cycles per second can be optimized even more.
The phone won't go up all over the way to 1.4GHz when idle, but will maintain a very low cycles per second clocks, thus improving battery life
Here's my experience w/ battery life and overclocking the Desire Z (for today).
I only have it set to overclock to 1GHz and I have typical SetCPU profiles to underclock to 245MHz when not in use.
My phone has been off the charger since 9am (5.5 hours) and is sitting at 92% battery power. This includes permanent connection to WiFi (no sleep policy), receiving updates to email/gmail and some text conversations with Trillian and a 15 minute email (composed w/ keyboard).
Compared to my old HTC Hero (Running VR 1.5.0), this is a huge improvement, though with VR 1.5.0 I could run JuiceDefender & have similar battery life with the right profile setup.
Yup I even notice better battery life in actual use. My friends were running youtube and doing web searches like crazy on my phone last night + games for a good 5 straight hours and the battery was holding up well.
I've got to say, the battery life on the Desire Z is outstanding... 18 hours with light use and battery still @ 92%!!!
What about 1GHz core compile?

are you using set CPU and overclock?
Is anybody getting time without a signal percentage in the cell standby item in the battery usage? Im getting 12% sometimes more and im getting about 14 hours battery life with moderate use! I dont feel im getting the best out of the battery and worried this might be part of the issue!
Hi guys.. sorry for the novice post.. i have had my Desire Z for a day and am interested in overclocking it - but
a) are you saying it possibly INCREASES battery life?
b) is the speed diff noticeable in day to day use - or just benchmarks?
c) How do i overclock - what is SetCPU and how does it work?
I don't think my battery has settled yet .. I hope not anyway, and I just (temp) rooted and overclocked to 1Ghz last night, haven't tried higher yet because I feel like my battery is kind of just disappearing so far, none of this epic "all day and then some" stuff some people are reporting. I think it may be that fact that I've been using the device pretty sporadically so far, and it hasn't had a chance to settle.
Also "cell standby" seems to be using a lot of battery, and I'm thinking that's because I'm unfortunately in a spot where I get extremely poor to no coverage most of the day. So I'm thinking the cell radio is using a lot of juice trying to get that 1 bar I sometimes see here. There didn't seem to be a way to easily disable the cell radio without disabling wifi though, until I found this "airplane mode wifi tool" on the market which I just installed.
So now my cell radio GPS and bluetooth are all off while wifi is on, hopefully that will make a difference. I'm wondering if using 802.11n is more draining than 802.11g also I know both my router and the desire z support N but "network info II" reports I'm only connecting at 65Mbps, while my laptop connects at 150Mbps.

I don't think there's any way overclocking can actually increase battery life, but managing CPU speed with SetCPU seems to be more effective than the default behaviour for some reason, so the fact you're overclocking when using it but underclocking when not using it results in longer battery life. I'm pretty sure it does regulate the speed automatically without setCPU but maybe it doesn't clock the CPU down to absolute minimum by default when the screen is off?
Anyway the noob friendly guide to overclocking by JD is on the forum with an [INSTRUCTIONS] tag.. I can't link to it apparently since I'm a noob.
Edit: Added link ~TheRomMistress
Thanks guys. Main thing i'm curious about is whether i just install SetCPU or i have to "root"
Yes, SetCPU needs root access.
Still trying to figure out how the OP is underclocking to .3 using SetCPU.. Lowest I can go is 245..
Unless I'm an idiot and completely missing something.. I'd love to turn this phone way down when the screen right off. As it sits, I'm lucky to get a full day from a fully charged battery.

You can check by yourself and then uninstall if you are not satisfied (or just reboot and changes will dissappear, since we don't have permanent root yet)

Battery Performance Tip

I know people are always complaining about battery performance, or see stories of how someones phone will go from 100-40 in an hour and half to two hours. I think I've found a solution (notice how I said I THINK). I've seen random battery fluctuations on my device for months now, some days it lasts longer than others (obviously data off, wifi off, and all that good stuff) but the battery life would still be eaten away like crazy. Here's what I noticed a few days ago: I went to sleep and when I woke up the next day my battery life had dropped 20 percent overnight, and everything that sucks battery was off. It confused me because that doesn't happen unless I leave data or wifi on. So I looked through the phone and I turned off "Standalone GPS services" one night and went to bed again. The next morning, the phone battery had only dropped 2 percent!
tl;dr turn off Standalone GPS under Location and security settings. IT may help your phones battery life significantly
Hope this helps with your battery performance folks, and if this has been brought to your attention already, then sorry for the repost!
just thought i would reply
first of when i sleep if i need the alarm i turn the flight mode on as the battery only uses between 1-4 % a night normally 2
i dont have a standalone option only turn gp on and off
r800i 2.3.4
but i dont have any battery issues really if my battery is draining fast its because im playing a game or browsing the web alot
a good tip is
use wifi instead of data when a wifi network is available but keep wifi off when not in use.
too many people either leave wifi on all the time which wastes alot of battery or never use wifi as there confused and always use data connections even when at home (major battery killer)
What happens with my battery is that if I leave the phone on standby overnight it'll gain about 10% and that's not even in airplane mode.
But as usual my battery does drain quite a lot when playing games using wifi and all that. Using EDGE drains more than using wifi.
I always charge my phone every night so would turning off the gps help much during the day?

Each has its own pro's and cons. Here is a list:
Lithium ion:
-The lightest of all metals
-The greatest electrochemical potential
-The largest energy density for weight.
-The load characteristics are reasonably good in terms of discharge.
-The high cell voltage of 3.6 volts allows battery pack designs with only one cell versus three.
-It is is a low maintenance battery.
-No memory and no scheduled cycling is required to prolong the battery's life.
-Lithium-ion cells cause little harm when disposed.
-It is fragile and requires a protection circuit to maintain safe operation.
-Cell temperature is monitored to prevent temperature extremes.
-Capacity deterioration is noticeable after one year (whether the battery is in use or not).
Lithium Polymer:
-Lithium polymer chemistry differentiates itself from Lithium Ion in the type of electrolyte used (a plastic-like film that does not conduct electricity but allows ion exchange - electrically charged atoms or groups of atoms).
-The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.
-The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry.
-Cell thickness measures as little as one millimeter (0.039 inches).
-Can be formed and shaped in any way imagined.
-Commercial lithium polymer batteries are hybrid cells that contain gelled electrolyte to enhane conductivity.
-Gelled electrolyte added to the lithium ion polymer replaces the porous separator. -The gelled electrolyte is simply added to enhance ion conductivity.
Capacity is slightly less than that of the standard lithium ion battery.
-Lithium ion polymer finds its market niche in wafer-thin geometries, such as PDA batteries.
-Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
Ice Cream Sandwich (Beta) already has this feature off by default.. but great tip anyway.
yeah i know my battery sucks too but it vary's sometimes
You could try out apps like juice defender. It disables your data connection and enables it every 30 minutes for example, to update whatsapp etc. When I am at home, I use our WiFi network. My play has the best battery life of all my friends phones and I'm a heavy user, playing a lot of games and using the internet too.

You need to try the ultimate version. You can select what happens on specific apps. So apps that dont use the internet, the data will be disabled whilst playing them
Also, you can set it to automatically turn data on/off depending on your location so you connect to wifi at home ect
I find it very useful

3G Drain on Jelly Bean

Are we likely to see a fix for this? We know there is a problem with 3G drinking battery but how likely are we to see a fix. Solutions like disable 3G aren't viable for a lot of people, so I just wondered what peoples thoughts on this were.
Try changing your modem. You should see a slight improvement in battery life, nothing major but still better than nothing.
Sent from my GT-I9000 using Tapatalk 2
Yeah a modem did help but I still had a big problem. Are we likely to see a fix, I remember this being a problem with ICS which is why I reverted back.
Its not the modem. My phone stock uses the XXKG3 modem, and i have been using that on ICS and now into JB. Jellybean definitely has worse battery concerning 3G / H for some reason. I just barely squeeze a day out of mine.
Yeah, I was struggling to get even a day. I tried almost all of the Jelly Bean ROMs and they all suffered from the same problem. I really wanted to stick with JB, especially C-ROM because it was like a dream to use but on a good day I'd get about 7 or 8 hours maybe? I would always have to plug it in twice a day. Currently trying SauROM which is better but I'm starting to think that the best for battery life is genuinely a stock rom like JVS.

did you limited your speed to 3g or do you also use hsdpa? if you use hsdpa, give 3g a try i think the battery drain in 3g is a lot lower ... in my opinion if you are not downloading 3g is fast enough to browse or youtube.
for just instant messaging you can give 2g a try
2G isn't really usable on Three mobile.
I don't know how to limit to just 3G. But yes I normally use HSPDA. That said, we should be able to use it without draining our battery
I'm not getting any major battery drain here. I can last a full day on HSDPA and or WiFi.

You CAN limit to just 3G. You have to go to Advanced Settings or Galaxy S Settings (depends on a ROM) and go to HSDPA and put it to UMTS mode only. It'll switch it to 3G and will consume less battery

in my opinion, thats the point, go to settings/advanced/RADIO in your case hsdpa + hsupa should be ticket, simply tick umts an you should notice, the changing radio icon in the status bar (no longer h, but 3g).
your 3g and hspa power consumption depends really strong from the signal strenght and in your phone is connected constantly or changes often. bad reception causes a large waist of battery power.

On slim 2.9, I found that removing G now, and turning off all location tracking increased battery life. Now I can get a day and about an hour/90mins of screen on time with data/wifi only on when using it. I suppose after more than 2 years of use on the one battery charging every day or more, there's only so much one can expect from a device and battery.
But isn't it recognized that this is a problem? The 3G Bug? Nothing to do with Google Now etc

Battery life discussion thread

There doesn't seem to be a thread for discussing battery life, so here you go.
I've been quite happy with it, lasting 2 days on average before it needs a charge with light to medium use (Messaging, web browsing, email)
Few battery charts: http://imgur.com/a/d0V2F
the priv battery have been good with me, it can last a day full without charge, a heavy use of gaming also can last a day
I've had opposite results with my battery. I get about 6 hours with light to medium use. I've only had it a two days so I'm assuming like all my other androids it's get better after some use and a few recharges.

Theres a few things that also improve battery life significantly, going into developer options and changing transitions to .5 or off completely, and if your in an area that doesnt have GSM or CDMA, you should turn that option off in your network signals.

Sent from my E6653 using Tapatalk
From what i've read on numerous forums, the battery level drains a lot faster when subjected to certain task. For example, gaming does not seem to put a huge amount of strain on the device or battery, however general web browsing does.
Same goes for the heating issue - I've yet to actually document what puts the device under strain causing battery life issues.
For me - as a rule, the battery isn't so great. It's better than the Z5 which I sent back, but around 2/3 as good as my Moto X Play. I'd expect the device to be lasting a LOT longer given the battery capacity (near on par with the MXP) however, as mentioned there are certain tasks which seem to drain the battery quicker than others.
I usually get around 3.5-4 hours screen on time a day out of a full charge.

Most of these will make tiny differences that wont really save the battery life enough for an end user to notice. Things such as scaling down animations will help with the performance slightly which, yes, will affect the battery but we're talking 1-2mAh per day.
Yeah I'm noticing pretty stinky battery life on this guy compared to my G4 which is weird because they both have an 808 and the battery is larger on the Priv along with a smaller screen. Really like the phone overall but I'm not at all enthused by having to charge this thing constantly. Plus it's always running hot for me even if I'm only using it to respond to a text message or two. Really not happy to have to return it. Also seems to get laggy for me on Google Chrome which is lame. Very high potential phone I just dont have the time to wait and wait for updates to fix the battery and heat issues.

That's a shame you're going to return it but understandable - I am confident that BB will improve the battery performance over time, but it's just a case of when. The pro's of the phone (power, speed, screen, camera etc) outweigh the need for a good battery life for me.
Keep us posted.
Agreed. I really liked the phone but mine gets hot and laggy and I've got the screen click in the bottom left corner and the back has that strange hollow feeling that seems to be complained about all over Crackberry. It could even just be a t-mobile thing but I don't want to take my chances especially when the phone is so expensive. Fingers crossed that they release an awesome update or skmething for this phone, though. But with just 25 minutes of screen on time (phone on for just one hour total) I've lost nearly 20% battery. Can't figure it out either. Brightness all the way down, Bluetooth and WiFi off, Gmail sync off, WiFi calling disabled, BBM disabled and it still is hot as could be and eating battery. What I would do to have access to wake lock detector!

For me - as a rule, the battery isn't so great. It's better than the Z5 which I sent back, but around 2/3 as good as my Moto X Play. I'd expect the device to be lasting a LOT longer given the battery capacity (near on par with the MXP) however, as mentioned there are certain tasks which seem to drain the battery quicker than others.
I usually get around 3.5-4 hours screen on time a day out of a full charge.

Most of these will make tiny differences that wont really save the battery life enough for an end user to notice. Things such as scaling down animations will help with the performance slightly which, yes, will affect the battery but we're talking 1-2mAh per day.

Truly, after completing all of these battery tips, i didnt even do every one on that list, but changing the sync + radio + animations has DRAMATICALLY increased my battery life, went from half day to full day without charge. Radio definitely seemed to be a HUGE drain when trying to access GSM in my area. animations i cant say made a huge increase but the phone is SO much quicker, felt slow and laggy with it on.
Ok, so I have been running my phone a few days now with the new setup. I am now getting 11 - 12 hours of battery with moderate use. That's about twice what I was getting. So it's now comparable to battery life of other phones I had.
So I have the T-Mobile variant, the SVT100-1. My guess was it was all the bloat ware TMo put on the device that was eating g battery. Here is a list of the apps I disabled, since we will probably not getting root and won't be able to uninstall them.
Lookout (BlackBerry App)
Mobile money(TMo)
TMobile My Account
TMobile TV
Visual Voicemail (TMo)
Yahoo Finance
Blackberry Help
A few of the Google keyboard input languages (these more for space nothing performance)
Over the next few days I will enable each one to see if it effects battery life so I can determine which one is killing battery.

I've had opposite results with my battery. I get about 6 hours with light to medium use. I've only had it a two days so I'm assuming like all my other androids it's get better after some use and a few recharges.

Were you able to narrow it down at all?
I'm getting around 4-5 hrs of screen on time - around 16 hrs with moderate use. I notice it heats up quite a bit while on chrome.
Hoping the update to marshmallow will help with the advanced standby feature for apps. Wifes s7 edge has crazy battery life and it only has a couple hundred more mAH capacity. Going to try enabling only 4g/3g since it looks like I have weak LTE signal everywhere I go.

Uploaded some benchmarks and battery stats.

A few days of using pure stock, I have made a folder containing screenshots of my benchmarks and battery.

How do you get such a good battery life? Please tell us!

That's impressive. What kind of screen on time were you getting with your prior phone?

I had a Sony Xperia Z3+ and when it was pure stock I would get 3-4 hours but that was with a disadvantage, I had to tailer myself to not game or use it heavily as it had the notorious SD810 and would easily hit 80°c while browsing and playing simple games. When a kernel came out SOT didn't improve much just user ex and heat. So yeah this 3T tops it in all my main areas sound, camera and can use it however I feel. :highfive:
First charge.

I haven't done anything, using dark theme's where possible but other than that it's just my daily usage but constantly. Today been using it on YouTube, Tidal streaming, browsing and playing pinout. Sitting at 25% 6H 48M SoT. I f**king love this phone. Just wait till I root and get the tweaks back on
Did you even use your phone? I bet you just enabled so the screen doesnt turn off and placed it on desk.. Thats unfair if you did that as the cpu is running on low mhz all the time
Some people get good battery on every device and some people always get bad battery. I always get great battery on all my phones and this one is no exception. I've hit 10, 11, and 12 hours screen on time and have not done anything to save battery.

No I used it. Why would I "just sit it on a desk"?

To hype up and get attention. I really dont understand how can only you get such good battery life while the rest of us are having significantly worse stats
I believe you tho, 3400mah is not a small battery plus you posted a lot of stats /graphs and details about your battery usage

Yeah because I come on XDA for attention
Temperature changes wouldn't happen if it was having a holiday on a desk? Or high constant WiFi data if I wasn't streaming music.

People do a lot of stuff here just to get likes xD
I get 7-8 hours sot, using my 3T as any other phone.
I used to get aswell 7-8h on the Oneplus One, constantly on WiFi (with LTE it was worse, 5h SoT). Mainly using chrome, tapatalk, flipboard. (no games).
Now on the 3T its pretty the same (7-8h SoT on WiFi).
ofc games will drain it alot more. its depending on usage.
you also get different results when ure on Enterprise WiFis (high dtim interval, authentication system, etc.), then your WiFi could consume much(!) more battery.
at my work, even 4G takes less power than WiFi. While at home, wifi takes nearly nothing (8h idle on wifi = 1-2% max. drain)

Make a good point about the WIFI. My Asus has this option, I enabled when I got it.

I get your point, but this is not the case. See my print screens in this thread -> http://forum.xda-developers.com/one...ife-sd821-400mah-t3505786/page10#post69935470
Its helluva device (the combo of HW and well optimized OS).

Dsl-ac56u been going strong but want to upgrade soon.
Pretty good battery here. Getting 7 hrs most times although my s7 edge exynos would give me somewhere from 5 hrs to 6.5 hrs sot, O3T SOT is amazing.
Hi @LMcR92 bud very good scores and stats
