Re: Xperia Z battery life

Your note is badly configured I'd say. With very heavy usage I have17hrs uptime and screen on time of 10hrs..so no Note 2 battery is not average.

Gotta Agree, when I had Note 2 battery life easily 8 hours + on screen time, I never had to worry about charging it at all.

With my Nexus 4, I can achieve 4-5hour on screen time, this including certain tweaks in areas.

"There’s a lot to like about the Sony Xperia Z. It is the strongest Android phone that Sony has produced to date, fusing power, design and features. We don’t find Sony’s customisations to be too intrusive and the attention to battery life is to be welcomed. The practical waterproofing also means you don't have to worry when you drop your phone in the toilet, or spill a pint on it, and these things happen.

It’s not perfect, however, and the camera doesn’t appear to offer much over previous flagship Xperia devices. It’s a reasonable performer, however, but with rivals focusing all their attention on the camera, it’s not the greatest feature of the Z.

However, the display size, in this design of handset we like a lot. With some larger devices, you feel like you’re compromising to for the sake of having a large display. The Sony Xperia Z plays its hand nicely, giving you that large screen experience, battery life that’s well managed and overall performance that makes daily use a pleasure."

I have used now my XZ now some days.

on the first day I was just :eek: and though I can see the percentage numbers go down every minute on normal use.

now after 4+ days and few charges its lot better.

I can use it 2days w/o stamina mode in moderate use(email/whatsapp/browsing/../no gaming no wlan) and so its not worse than my Note I had before.
[Xperia Z Q&A, Help & Troubleshooting] Akiainavas:
After using the phone for over a week now I can honestly say that:

- Lasts 6-8 hours of constant heavy use, as in toy-mode

- Lasts 1 full day, as in 6:00 to 22:00 of heavy use

- Lasts over 48 hours when used as a phone, as in 1-2 hours of mp3, texts, few phone calls

It could be better, battery life could always be better, but i'm pretty happy with it. It gets me through the day without worrying about saving energy - that's all I asked for.
[Xperia Z Q&A, Help & Troubleshooting] XDA mark:
A friend of mine already got his Z and we talk everyday on whatsapp. He unplugged the device before 10 in the morning at at 12 his battery percentage dropped from 100 to 99%. He said he listened to 10 songs, checked facebook, instagram and used another app a bit. Always connected to internet (I guess mostly wifi at home and 3G when on the move).

He actually send me a screenshot of his battery stats, which showed he wasn't lying (2h and something on standby, 99%). I told him to look into his screen on time and he said 30 minutes.

Now this sounds incredible, but even so he wouldn't really have a reason to lie to me. Even if the battery life turns out a little bit worse then what he said, it would be very nice.

I'm getting my own XZ tomorrow so will post here with first impressions.

edit: also, he ended the day late at night with 10% left.

I've just read the user guide and it mentions another mode called "Low Battery mode". What does that do?
[Xperia Z Q&A, Help & Troubleshooting] hebbe:
Stamina mode is so awesome!

i charged the phone 'till 11pm up to 100%, then went to bed. to be honest, i put the phone to airplane mode overnight. after 8 hours of sleep, i turned on the screen: battery still at 100%. is this possible?

then turned off airplane mode. now it's 9:50am, so using 3g for nearly 3 hours and guess....the phone is still on 100%! to be honest again, i didn't do anything with the phone, except turning on the (lock)screen 2-3 times for checking on new sms. that'all.

amazing.
[Xperia Z Q&A, Help & Troubleshooting] orenxda:
Re: Xperia Z battery life

Thats bc youre on 3G but not using the phone, stamina mode cuts data and yes that standby mode is impressive.

Low battery mode needs lil config for how you want he phone to behave when it reaches 30% charge: screen brightness, turn off data, wifi, gps, sync...

Btw watch out not to run out of power if you need the phone, charge before it reaches 0: if the phone turns itself off at 0%, you wont be able to reboot at all, even plugged in, until you let it charge for 15 minutes.

Can be annoying in some situations.

I don't see how you can make some progress here while retaining exchange with push. Switch it to 30min sync? Underclocking to 1.24ghz should also save you some battery in those 35mins.

Guess that this one before with 2G somehow bugged and disconnected mobile data :( There is no other way to explain the 0.3%/hour

[Q] Omni Rom vs Stock battery draining comparison

Hi everyone, I hope all is well!

I'd like to ask if anyone could share their thoughts on omni rom kitkat vs. stock rom battery draining comparison.

I'd been using stock with XzKernel until 2 days ago, since then I'm trying out kitkat omni rom 4.4.2 because I was impatient to get kitkat before its official Xperia Z stock release.

For these 2 days I can only compare active usage (screen mostly on, moderate to heavy wi-fi/3g internet, audio and phone tweaking usage);

I haven't let it to go to deep sleep for long (except while charging overnight), and I can say that the battery life is similar (around 5 hours at the above usage); before that I was getting 6-7 hours max with the same usage.

As for the longer deep sleep usage on stock, the most time I've managed to get was around 48 hours (with wifi/data always on, Stamina Mode and Greenify on, low internet/audio usage, >80% of the time in deep sleep).

The whole point of this post is that I'm still trying to decide which rom to use, with battery draining being a big influence on the decision (with no big decline in performance, of course).

Off topic, I've read somewhere that a way to calibrate the battery is: 1) charge to 100%, 2) empty to 0% (without partially recharging), 3) charge to 100% again with the phone off for around 3 hours.

Is this true, and if so, what are the benefits of calibrating a used battery?

Thanks in advance for your answers

Kind regards
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
Everybody has there own way of battery calibration, and everyone is certain his way is right xD

As for the screen on time! Did you use auto brightness or manually set to lowest?

There mostly is MORE drain on AOSP or CM ROMs because Sony Stock ROMs have better throttle management for the SoC. Maybe if you have a heavily for your device optimized Custom ROM the governors, overheating limits a.m.m are well enough optimized to bring better battery life.

BTW, currently on Slimkat, 2Days standby only 30mins SoT an still 65⅝ Battery left.
[Xperia Z Q&A, Help & Troubleshooting] airlessproject:
Brightness manually set to brightest, I kinda like it better that way, would sacrifice a few hours for that. :)

I'm currently trying out a custom kernel from some guy that hasn't yet published it, there are some optimizations implemented, like governors, thermal control etc.

Wow, that's really impressive :) do you have 6602 or 6603 (or maybe other)?

You could talk me in on trying Slimkat :) Are you heavily or moderately optimizing it for battery? (brightness, greenify everything, thermal control, undervolt/underclock CPU/GPU, governors - did I miss something?)

Cause I would like the device to perform well too, I would have bought a slower and lower budget phone if I was that in for battery life and compromising on performance..

Anyway, thanks for the answer :)

Kind regards
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
Xperia Z1 Compact, best phone for battery life ^^

But you get 5h Screen on Time on brightest setting ? How ? Unplug the phone and browse the web for 5h ?

On Stock rom i got about 3-4h Screen on maximum, before i hit 10% battery. But that was about 18h-24h usage and not only Screen on Time.

Btw SlimKat, i installed Greenify, did Greenify WhatsApp, Tapatalk and Facebook, thats about it. No undervolting or any other changes yet. Still two Exchange Email accounts working the whole time. (EDIT: oh right, C6603, i DO have LTE sometimes, but i use Gravitiybox (Xposed) Signal manager = Screen off turns 2G on and deactivates LTE/3G)

Thats with roughly 45 mins Screen on ^^ so mostly Standby.
[Xperia Z Q&A, Help & Troubleshooting] airlessproject:
Oh, I might have not explained it right, in my previous post I said moderate to heavy internet/audio/phone tweaking usage, which assumes a couple of hours of standby time added :) I surely didn't unplug the phone and use it constantly for 6 hours :)

Today I used the phone only moderately, and this is my result:

I guess I have some extra wakelocks given I'm constantly online on every social networking app I use except for Skype (that includes Facebook/FB Messenger, Hangouts/Gmail, Viber, Last.fm..), and I also used music playing on screen off, which is additional wake time. I'm also all the time on wifi/3g, so I don't revert to 2g on screen off.

Since I don't have a second phone, it is uncertain when I can do a full deep sleep test to see the results from that, but it'll be soon enough, and I'll return here with them.
