[Xperia Z Q&A, Help & Troubleshooting] drsoran2:
since I backuped and then uninstalled and rebooted my XZ (a freeze with TB didn't work, was still running!) "com.sonyericsson.wakeup..." my deep sleep over night went up from around 85% to 98%! This was on 3G and without stamina mode. I have yet to test with wifi and stamina enabled and I guess it will be even better. The process I froze caused up to 2400 wake ups within 30 hours that the phone was off charge! It was insane. This process is responsible for fast dormancy, but since it's gone I didn't experience any drawbacks.

Standby time is now even better than before. It was already very good before.

Now the highest rate of wakeups or alarms that BBS shows me is "android" with 131 since 17 hours. That' a major difference to before.
[Xperia Z Q&A, Help & Troubleshooting] diego9016:
But what exactly is that com.sonyericsson.wakeup? Is it really safe to remove?
[Xperia Z Q&A, Help & Troubleshooting] DoubleYouPee:
Same, com.sonyericsson.wakeup has completely disappeared when removing fast dormancy.apk.

Highest alarm wakeup is exchange service..

Only not-normal kenrel wakelock is still mmc1_detect
[Xperia Z Q&A, Help & Troubleshooting] drsoran2:
"fast dormancy" which is that "com.sonyericsson.wakeup" process is supposed to better your standby time on mobile data. However, some networks or phone providers don't support it or not properly and therefore it drains more battery than without it.

I don't even know if my provider supports fast dormancy and frankly, I don't care anymore. I see the improved results and that is enough for me.

I have that mmc1 wakelock too, but it's not so bad. I don't know what causes this.

Well, after removing the cause for the highest wakelocks, something else must take its place. There has to be a number one.

Where exactly did you find com.sonyericsson.wakeup ? ( via explorer i mean ) i would want to delete it too because only deleting my fast-dormancy.apk from system/app didn't do squat ...

I know that usage patterns vary, as well as settings, however, this is a battery life thread and it could be interesting for other users to see what they can possibly achieve. Or if they are very far off with their results.

So here is mine, after uninstalling "com.sonyericsson.wakeup.." process (which is responsible for fast dormancy". Since deleting it, my standby time and I think also my on screen time as considerably improved.

As you can see from the screenshots, I got 1d 18h standby and 4h36mins screen on time! I've used stamina all the time and wifi whenever possible.

What I did: facebook, web browsing, twitter, instagram, e-mail, whats app, texting, taking pictures, using a push up, sit up and a squats app.

The standby time could have been even longer, but then I decided to heavy use the phone and drain the battery to see how much screen on time I could achieve after this long standby time.

I'm very impressed with these results.

I am seeing alot of wifi, mobile data maybe from 1 or 2 minute of synching. you cant really compare battery life to other people, alot of factor come into play...screen brightness, ambient temperature (yes temperature play a big part in battery draining), mobile data vs wifi, how they use the phone, browsing with screen on is different then gaming with screen on. so no you cant really compare at all, people dont understand this and they wonder why they get horrible battery compare to other. UNLESS you post a before and after screenshot...sort of like a sciencetific study... u gotta have a control variable and the experimental variable, if that make any sense.

At that time I was sleeping. My battery is living for day and a half, max two days. I just wanted to see if it can live 3 days with using when I must ;) for some extraordinary time :)

Brightness is always on 56%. As I said, this is NOT how I use my phone. That was a test, just to see what is this battery capable of.
[Xperia Z Q&A, Help & Troubleshooting] drsoran2:
[MENTION=4192818]DoubleYouPee[/MENTION]

my brightness is always set to auto and the slider is in the middle position and I usually get 24 hours or one and a half day with up to 3.5-4.5 hours screen on time.

Here's my latest finding: 99,1% Deep sleep over night!! This is with wifi and Stamina on over night and of course after uninstalling "com.sonyericsson.wakeup..."

I've only lost 2% battery in 8 hours. From 100 to 98% which makes 0,2% per hour.

I think this is close to what old dumb phones did achieve.

I don't think it can get any better. I've never had such a good deep sleep and I thought that 85% was already good...

The XZ really has amazing battery life and if you root and get rid of a couple of apps, bloatware and this process and also apply the right settings and tweaks, the battery becomes AWESOME!

since the.253 update I'm getting great battery life. stock, stamina mode on and auto brightness on low to medium.

Google now and Location history is also enabled so is Google's location history. I sync 3 e-mail accounts every hour as well as the usual Google syncing. I dint have Facebook so I disabled it. my wake locks are pretty good mostly maps and a little bit of essential items.

I'm getting 3 hours screen time and the battery is lasting me up to midnight after taking it off charge at 8 am.if I'm at home I'll use Wi-Fi and I can get up to 4 hours but in a normal day it's 3.

good enough for me as I mostly use the phone for calls and web browsing. if I do heavy web browsing or watching videos I can always plug in a charger. And if I wanted to I could disable a few things and get better battery life but then what's the point of buying a500 pound smartphone if you disable half its functionality.

One question

While charging when percentage reaches to 90 or above LED turns to green. Is this normal? Is it not supposed to turn green when it reaches exact 100%.
[Xperia Z Q&A, Help & Troubleshooting] jigodiass:
It is happening to me too, so i guess is normal.I can`t remember where i read it but until 90% the battery is charging faster and over 90% is charging slower to avoid overcharge and damage the battery. So is sort of protection.

When the battery is almost discharged the phone turn off by it self to avoid the complete discharge of the battery - this also damage the battery - and again...a sort of protection.

Fast dormancy allows for different stages in 3G connections to save battery (e.g. connected but no data) but if your provider doesn't support it will keep waiting for a signal from your provider.

Hello all,

I'm pretty pleased with the battery life but one thing is buggin me.When i use my Sony Z in the car with a TT navigation my battery decreases 1% every 10 minutes or so.

I have no opend apps and i use a 2AMP car charger. I don't believe that a navigation software consumes a lot of juice and my screen is set about 50% brightness..

Lets say i have 5% of battery on my sony Z and i want to make a trip with my navigation on, i think i can shake it..

You think 1% per 10 minutes with screen, gps and internet on is much? That will give you over 16 hours of screen time from 100% to 0%. I don't think you're actually gonna make that ;) But 1% per 10 minutes seems pretty decent, especially with brightness at 50%.

[Xperia Z Q&A, Help & Troubleshooting] cordonbleu:
Go into settings and then battery stats. Above the battery graph you can see your actual battery percentage and next to that you can see the type of charger you're using at the moment. This can either be USB (slow, 500 mA) or AC (fast, 1500 mA). When it shows USB while connected to your car charger, then that's the problem. When is shows AC (as it should be on a 2 A charger) the phone simply takes to much power to be able to charge and even consumes battery. Then there is not much you can do about it I'm afraid.
