KK has very power Battery usage I mean only 3 hours screen time and 18% left and most of the time the phone is on standby! I had much better results on 4.3
[Xperia Z1 General] YorubaDey:
Been having battery drain since 4.4 update.

Before I got fully charge the phone before I went to sleep, when I woke up it'd be at 99%. Now when I wake up, it's at 93% out of nowhere. Definitely something iffy going on.
[Xperia Z1 General] Riaes:
Hi, what do you think about these? Also about the ram usage, it seems so high

I don't have many apps
[Xperia Z1 General] Jiyeon90:
Freaking kitkat reduced my battery life drastically, I think it has to do with the SD card restrictions.. Damn you Google

om xenonHD Rom (unlocked BL) I'm coming through the day very well but it feels like it isn't that good like on stock rom.. I think this is because of stamina (used it everytime).

BUT: when I bought the phone I thought the battery is better
[Xperia Z1 General] romanpatel:
****t!! Nvr had such less battery!! If i used over 3G it doesnt evn last a day!! Why is it so!! It lasted atpeast a day on 2G. Any solution for this?? I dnt want to start stamina mode.. Hvng 4.4.2 stock rom.. Pls suggest..
[Xperia Z1 General] xplod2841:
How much do you use your phone? You should keep in mind that 3G spends more battery than 2G. Also, this phone can last about 5-6 hours with screen on when you're surfing on internet and about 2-3 hours MAX when playing heavy games. Furthermore, if you have lots of apps working in background and STAMINA turned off, it will drain your battery in standby as well.

So if you use your phone all the time, don't expect it to last more than a day. My suggestions: see if some app is draining your battery while the phone is in standby. It should drain about 3-5% battery during night (for about 7 hours of sleep). If it drains more, try to turn on STAMINA. Put your brightness on minimum when possible (except when youre outside and it's sunny).

Take a look at mine battery today:

I didnt use the phone almost nothing and stamina was on but it still drained 50% of battery. Why? Because I installed an app called Auto Screen On which was keeping the proximity sensor turned on all the time and it was draining the battery. So you have to be careful which apps you install and use. If you have apps like facebook, e-mail, tapatalk etc, these apps will regulary check for new messages, posts etc and for this they have to use CPU and interned, so they will drain the battery. This is why stamina is great but if you want to instantly receive all messages, face the fact that your battery will last shorter.

I have great battery life on 757 firmware.

As I already posted battery life (many times) today I'll post this :

Awesome standy (over the night)
[Xperia Z1 General] drsoran2:
Use "Proximity Screen off (Pro)" instead of "Auto screen on". I'm using it for months and it has only a small impact on battery life. With the pro version you can even chose apps for which the proximity sensor will be deactivated when using that app.

I for instance have it automatically off when in landscape and Album because when showing pictures or moving the phone around to another person it happens more often than not that they accidentially cover the sensor and the display goes off and this is annoying.
[Xperia Z1 General] xplod2841:
Thank you for your recommendation, I'll try it. I wanted to achieve double-tap to unlock but Auto Screen On was working poorly: I had to tap it slowly and it took some time to turn on the screen. So I'll try this but I don't think that any way with proximity sensor can work as good as double-tap to screen-on.
[Xperia Z1 General] pallegd:
I also got terrible battery life after upgrading to KitKat. A factory reset and limited re-installation of apps did help some, but never got back to the pre-KitKat batt life

Then last night I went through the hoops of getting more detailed information out of Wakelock detector, and then identified AudioMix as the main offender for many wakelocks. That reminded me of the old old issue of touch sound battery drain, so I disabled the touch sound and screen lock sound and bingo, this has helped significantly. now just 10% batt drain in 7hrs, and awake time went from typ 40-50% to 10%
[Xperia Z1 General] BLiapis:
Best battery life so far was with stock .757 with 4d10h @ 30% left.
[Xperia Z1 General] Riaes:
How come you get so good battery life overnight? i will lose about 6-10% in one night. :(
[Xperia Z1 General] aP!2:
what rom and kernal do you use?
[Xperia Z1 General] funky0308:
Sometimes I lose 1-2% but mostly it's 0% over all night (6-8 hours)

Well...don't know how, I always had great battery life...

I'm on firmware 757 - [NUT], rooted and deodexed. - LB - so it's stock kernel.

Custom kernels could be the reason you have problems, I'm not saying it's reason, I'm saying it could be the reason.

Especially if you are using kernel features controled by pimp my rom...

But that's perfectly normal - more features and options - less battery life -

my post from another thread

well today I am completely and utterly baffled

Left my phone on charge overnight after having more difficulties during the evening and it is like a completely different device today, running cold and seems sluggish (touchscreen has a very slight delay) and I noticed that two of the CPU cores are inactive, it's like it got a FW update overnight that I am not aware of, going to benchmark it and see if something really weird has happened to the cpu

It has gone from running hot and serious battery drain to running cold and the battery is hardly dropping at all

later...........

well 3dmark got a bit of heat in there and maxed out, not running the unlimited test as the phone is now too hot

It seems that something dramatic has happened to my Z1 overnight and I am at a complete loss as to what

Two things I did yesterday

1 Uninstalled 2x smartwatch apps to do with the camera and photos

2. settings - accounts - google - Ads, reset advertising and ticked box to opt out of interest based ads, I think this is most likely what made the difference and fixed my battery drain and heating charging issues

hope this helps people with battery drain on KK
[Xperia Z1 General] Geoffxx:
3dmark unlimited score of 17511 so it seems to be working fine but what a change - it's a different phone now running perfectly and cold as it should be, I am convinced it was the google ads setting in settings accounts google
[Xperia Z1 General] XxLordxX:

[Xperia Z1 General] XxLordxX:
Hi,

I didn't save the final tests, sorry ^^'. Currently I'm getting at most 4 hours of screen on time, but considering that I'm listening to music for at least 3 hours in the day, then I can see why it can't get much more than this.

The screenshots I shared were in a cold day, I didn't listen to music on this device and performed small tasks (except for half an hour of gaming probably Oil Rush). I will try it again and share the final results this time ;).

[Xperia Z1 General] xplod2841:
Z2 has newer Snapdragon 801 chipset which has much better power management so it uses less power and has greater efficiency. Also, I think that IPS screen consumes less power than LCD TFT.

I think it's the screen making the most difference. I don't think Snapdragon 801 is that much different at all.

just deleted the file :/ one time i just reflashed and wiped Everything, including the internal and ext SD card. Installed only the nessecery apps like whatsapp and wakelock detector and used it like that for 2 days. I would try that if i were you. and try using a minimalistic rom, like iHackers v4.1 minimal. wait 2 days, if the drops happen again its for 80% hardware related i would assume :/ Otherwise, install your apps after 2 days of usage without drops and wait again 2 days.

[Xperia Z1 General] CM17X:
If you have not whatsapp, it means that you barely use your phone. Do you play on it? Also, I can assume that you don't sync your email nor get push notifications. That works, but, what's the sense of an smartphone?

What I do for achieve this (picture below) is disable some unnecessary service right inside the app
[Xperia Z1 General] E620se:
Sorry, my english is quite bad.

I do have WhatsApp and also use it.

I also get push messages an mails.

Most of the time I'm connected to WiFi (at home, at university...) and disabled bluetooth.

When I sleep the phone is in plane mode.

You're right, I usually don't play any games.

Only write massages, browse the web, listen to music...
[Xperia Z1 General] CM17X:
Oh, i ot you. You have stamina but excluding those app's. So yes, you have a good battery life on 4.4.4. My picure above was using 4.4.2 and the tweaks i've mentioned wihout ouch the kernel or stuff, bu for me, a person who use the phone constantly, is a good battery life IMO.
[Xperia Z1 General] :
So I got this today and I barely use my phone.

Shows how people manage to get a long battery life. It's not realistically possible for a normal, daily usage.

Then again, the term "normal" may be different for others so here I will describe my "normal".

1-2 hours of Youtube and about 1 hour of Facebook, 9gag and surfing the net. I get about 5 hours idle and my battery lasts for 8-9 hours.
[Xperia Z1 General] CM17X:
The really important statics should be "idle time" vs life time on battery. You can get 1 week of battery life and 5 - 6 hou4rs on screen by leaving your phone alone. For 4 days, and in the cast day, spent the battery browsing. And there you go, an impresive screenahot. The average user turn on the phone more than 40 times a day, and if you manage the entirely day with 20% left, you're good.

i bought a portable speaker (has built in lion battery of unknown size) to pair up with my Z1 when on vacation

speaker has NFC, bluetooth v3.0 EDR Class 2 and 3.5mm connection

btw NFC is only used when pairing the device right? after its paired music is streamed using bluetooth?

tnx
[Xperia Z1 General] CM17X:
As long as your phone have to send/recieve packages or signals, there you have a battery drainer.

That's my point. I see so many screenshots of a battery life that lasts as long as it can but it doesn't really help if you barely touch it. That's why I prefer seeing screenshots of battery life with a normal usage an average user would use up.

but which of the 2 (cable or bluetooth) drains less battery?

Cable.

Having recently moved from iPhones, I was sort of disappointed in the battery life for the first few days.

I sort of got into panic mode, and read the entire Xperia Z1 forum :D Installed every ROM out there, found SlimKit and PA to be the most battery friendly and now using PA as my daily diver.

I usually get 4 to 5 hours of on-screen time and that I think is actually good considering it has a high-res display and what not.
[Xperia Z1 General] jancarlos1597:
What about the iPhone? Had better battery life than the Z1? Or no?

Which one is faster in you opinion?
[Xperia Z1 General] CM17X:
iPhone is just brand and groupies. The Z1 have way better battery life than the iphone.
[Xperia Z1 General] srqrox:
iPhone is very cleverly designed device.

It has almost half the battery size that Z1 has so it charges REALLY fast. Add that to the fact that one had to sync songs from iTunes.Nuisance it sure was, but whenever you plugged it in even for 10 minutes it will easily recharge the battery up to 15 percent. You get so used to it that you don't even notice. Plus, iPhone sort of shuts the WiFi as soon as the screen gets locked and then switches it on get notifications and shuts it down again so, yeah I'd say even though it lacks on many grounds people at Cupertino know how to cover for the short comings.

I am an ultimate texter, and yeah my screen on time was better on iPhone.

I'd take it off charger at 6 AM, and throughout the day with insane texting and using whatsapp, and playing Threes (in battery conservation mode that comes with the game) it would have like 8 to 10 percent battery left when I'd get back.

Z1 lasts till about 3 / 4 PM, 5 is absolute max.

But even then, iPhone has this psychological effect that you have a super strong battery by charging so quickly. Full charge on my 4S/5/5C took never more than 1 hour and 40 or 45 minutes, 2 hours with usb charger. I am paranoid as **** about such things so yeah, iPhone had a better battery life.

That being said, my poor battery life of Z1 may also have something to do with more usage, when you get a new device you just can't let it lying on the table you have to pick it up tinker and play with it. Poor battery life was also contributed by this Android System process taking over 80 percent of my battery juice, they say it is a bug in KitKat. Now, when I am on PA (which I am sure is less battery friendly than Slim) I am getting close to 4 hours SCREEN ON battery time. From iPhone standard it is low, but from the 1080p display point of view I think it is just fine.

---------- Post added at 12:45 AM ---------- Previous post was at 12:39 AM ----------

I must be doing something wrong then.

I started using it when it was n KitKat 4.4.4 (.108) and could actually see the battery dropping percent by percent in front of my eyes.

That was the main reason I got into rooting scene because I had used CM on HTC ONE V ( a pretty low end device) and thought it might work here too. Sure it took some tinkering but I think I am good now.

For those having trouble with battery lives, install SlimKat.

I am not plugging or anything but having tried every rom there is for z1, tinkering with governors and using it for a day or two, I say SlimKat is actually the best. With wifi on and using Flow (Reddit Client) Pocket and Feedly after one hour and thirty six minutes (screen on time) I was down to 94 percent, and that's something.
