Im still learning how to tame my phone too lol. Ive been running both stamina and battery guru the past few days and have started to switch things up to see if it improves any. Not sure if there was a minor change with no stamina mode and only battery guru. Anyone recommend uninstalling battery guru and trying just stamina now that I have had my phone for about 2 weeks?
[Xperia Z1 General] xplod2841:
I managed to get great screen time. It includes 2 hours of music, web browsing (3G/4G and wifi), messenger, sms, tapatalk, flappy birds etc. Stamina was off
[Xperia Z1 General] goldsmit409:
Is this drainage normal? I am worried that my battery life is degrading I have to charge it every night, wifi or mobile data is always on plus I play games and watch series(1 hr max)

Also sensors.qcom is running don't know why
[Xperia Z1 General] BLEK0TA:
Qualcom sensors works cuz u have turned on gravity screen on off or similar application

I LOVE the battery on this phone. Coming from the G2 who's battery life is amazing. I was expecting the Z1 to be poor in comparison. But its just as good!! Well maybe a little worse but only by like 5%,... Got 5 hours screen on time!
[Xperia Z1 General] stanley08:
I came here to do some survey because I'm looking to move from Note 3 to Xperia Z2. So i wanted to use Z1's battery life as sort of a benchmark to judge what Z2's battery life would look like. But i guess TFT display would be different from IPS in power consumption and also, Z2 would have 3200mAh. So, who knows really? Currently I'm getting fantastic battery life from my Note 3, I live in Africa so battery life is really important as electricity is not the best here, Sadly.

I would leave some screenshots below and also advice that some of you go into my battery saving thread in my signature and look into trying the steps there, as i have applied them and see if your battery life gets any better. I would be glad to get some feedback. :)

60 hours Standby time, with 7.5 hours Screentime

9.5 hours Screentime, in 24 hours Standby time
[Xperia Z1 General] Riaes:
One simple question

Does your battery drain when in idle with mobile network/wifi on despite on stamina mode?

My battery almost never brain if no internet.
[Xperia Z1 General] addicted2088:
I've had the Galaxy S, Xperia neo V, Galaxy Nexus, Nexus 4, Note 3, and now the Xperia Z1. I never had a phone that would last me long enough - I'm someone who has a lot of apps with constant services in the background (an app for showing notifications like Windows Phone called Metro Notifications, Automate It for automating tasks, the social apps with Twitter streaming in the background). The Note 3 was, unfortunately, a disappointment in terms of battery life. While I would always get 20 hours of battery life, display time merely reached 3 hours and that too rarely, which was surprising given the previous Notes were known for great battery life. The Nexus devices, of course, sucked balls as is the tradition (Google is like a bunch of geeks that never leave their computers, probably taking that as an excuse to not fix battery life or put a good camera on Nexus phones).

But then came along the Xperia Z1, after someone stole my Note 3. This phone is it: 99 percent of the time I get four hours of screen time AND 20 hours of total battery life. Even on mobile data it lasts more than 10 hours on 3G. I never even use Stamina mode since I don't like to limit what my phone can do, which makes it even more impressive. The reviews I read of the Z1 said battery life wasn't that great, but those reviews went off tests that do a particular thing for hours, which isn't a typical usage scenario. In general usage, the kind of usage that consumers will have, it lasts really long.

In short, love the battery life on the Z1. So many phones, and this is the first time I've gotten a phone that's so good at it. I've had zero cases of something draining the battery too quickly by running quietly in the background. Awesome.

It looks like you don't really have a lot of stuff running in the background, otherwise I have no idea how your Note 3 lasts sooo long, haha. But anyway, guessing my assumption of you not having stuff in the background running all the time (like social apps, etc.), I'd say the Xperia Z1 could offer you pretty good battery life, especially if you use stamina mode when you really need to keep the charge. But not sure it'll match what you're getting with the Note 3, though I'm sure others can chime in with their experience here.
[Xperia Z1 General] Geoffxx:
don't believe everything you read - I have a mate who owns an S4 and he gets 6 hours max screen time - there are several other sites online that quote the same

anyway the point and fact is - as technology get more demanding on battery and battery technology is not advancing - the only way to increase battery capacity is to increase it's physical size - currently manufacturers are having to juggle between the - Size of devices - the hardware used and the demands of customers, the S800 chipset is smarter at using battery power but is overall as demanding as earlier chipsets but produces better performance - the result is better performance for same battery usage which in turn equals the same battery drain which is exactly my point - don't expect battery usage to improve unless there is massive innovation in battery design which hasn't happened for over 15 years, the only way to increase battery capacity is to make it bigger

Device designers have a set of minimum conditions they must meet in a new device - one of them is that a smart phone must last a full day without the need to recharge under normal usage conditions - that is the minimum expectation of most customers
[Xperia Z1 General] Morlock O:
I absolutely agree with you, I have not been saying anything about the battery life because I was waiting for real life usage from people... and so far from this thread, its all negative... :( I was hoping this phone would get me through a day comfortably (16-18 hours of normal - heavy usage)...
[Xperia Z1 General] Geoffxx:
I believe it will once the novelty of looking at the screen and playing with it every 5mins dies down lol

It takes about 2 weeks for the battery to condition and improve - I have had an XZ and a month with XZU and so far the battery is better or at least equal to both depending on what you are doing
[Xperia Z1 General] MafiaManV:
Finally ! . I knew GSMarena's results were totally misleading :mad:. To them it was normal that it gets same results as Z Ultra -.-'

Thanks for this :good::good:
[Xperia Z1 General] WhiteHartMart:
Not sure why I'm different, but after the first 2 or 3 charges this has got the best 'early days' battery life of any recent Android I've owned.

Maybe my usage habits suit it?
[Xperia Z1 General] Sean473:
Do you mind telling me why even after me stopping playing around with the phone, my battery is being eaten up by Android system and mediaserver... What to do about this?
[Xperia Z1 General] MafiaManV:
install wakelock detector, or better battery stats, charge you phone, unplug it, and don't touch it for 2 hours. Then post a screenshot from WD or BBS. We can't help you before you do that ;)
[Xperia Z1 General] Sean473:
Yeah found the issue... That google wifi location service thing..Disabled it should be fine now lets see..
[Xperia Z1 General] vito45:
I hope that Z1 display eat considerably less power when brightness is not set to 100% :confused:
[Xperia Z1 General] Dpk1:
Here is my battery usage. Almost 2 days standby (on 3G network) along with 4hrs 43min screen time with moderate usage. It includes:

- about 1.5hrs internet browsing (via chrome), some play store app downloading, etc.

- about 1hr of 3G calling

- about 1.5hrs of album browsing & camera use

- about 40min of video playing via Movies (not visible as replaced by MX player now).

- 30min 3G data use (chrome)

- 20 min of music via headphones

I think the battery backup is slightly better than XZ but it is just one complete cycle yet & I expect it to improve further after few recharge cycles. I'm on stock rom, no root yet.
[Xperia Z1 General] Geoffxx:
Thanks for that and I believe you are bang on with your comments

I went out tonight at about 8:30 and have been surfing - making calls - sms - taking photo's and video - it is now 2:45 and I still have 80% battery, that is pretty good to me, I've had 3 full recharge cycles which I did on purpose
[Xperia Z1 General] Sean473:
Yeah my battery life is much better on my second recharge!!
[Xperia Z1 General] maverick1103:
So today seemed a much better day, only charged the phone once and managed to get just over 5hrs screen on, haven't had this much since I owned a Note 2!!

I did have my brightness rather low I will add as I find it still pretty bright on 0% with adapt to light on.

I only imagine it will get better!
[Xperia Z1 General] vapotrini:
Judging from your graph, that's with extremely light usage though. Also, did you have power saver mode on or off?
[Xperia Z1 General] maverick1103:
I wouldn't say it was with extremely light usage, I used it more than normally, constantly on social networks, tech websites, taking photos of my little one etc. I think the fact I got over 5hrs screen on says alot.

Edit: No didn't use power save mode, stamina mode, just use low battery mode when I get to 15%.
[Xperia Z1 General] Morlock O:
That is awesome and a huge relief! Thanks for sharing... will definitely get mine soon!!!
[Xperia Z1 General] Sean473:
Lol 5 hours? Mine barely had 2.5 hours of screen usage.. Doesn't help that google services is eating up 25% of the battery :(... Also did you notice a bit of a yellowish tint in apps with white background? It seems there are no issues when playing videos etc but in these apps.... Its a bit irritating as my Nexus 7 2013 displays the white's perfectly!
[Xperia Z1 General] maverick1103:
Yeah man, today I'm on 51% battery remaining with almost 3hrs screen on.

How many times have you charged it yet? Man I had that Google services problem with my HTC One, not got it atm.

Nope mate, mines white as can be, maybe you got a defected device?
[Xperia Z1 General] Sean473:
Can you post a few pictures of your screen? Particularly when you open an app like lets say Android Central/Sky News...Open an article in them and post a screenshot... I don't think its a faulty screen since all the Z1's I've played around look like that..Maybe its just my eyes since I used to have an S3 with a Super AMOLED screen which had really bright and vibrant colours!
[Xperia Z1 General] maverick1103:
These Ok?
[Xperia Z1 General] stanley08:
I always have 2 email addresses syncing, Twitter, Instagram, WhatsApp, BBM (huge battery drainer), Viber, and Telegram. Sync always on. However, phone set to 2G only as i use WiFi only and I bought Greenify Donate. :)
[Xperia Z1 General] addicted2088:
Oh, wrong assumption then. Have to say you're really lucky then! Even on 2G and Wi-Fi I can never get that great battery life on the Z1, and certainly never got it on the Note 3! In fact, many of the people I know with Note 3's aren't that impressed with the battery life, on both the Exynos and Snapdragon version. :(
[Xperia Z1 General] stanley08:
Yes! That is the reason for my battery saving tips thread in my signature. Note 3 battery life got worse since release. Went from 8 hours screen time on 2G to 5 hours screen time. Now, u can only get decent battery life on WiFi, and that's why I bought a portable WiFi router. Something like this (http://shop.vodafone.co.uk/shop/mobile-broadband-devices/r206-mobile-wi-fi-payg). So now, i always get better battery. But Samsung really messed up with software, got better with KitKat but not as good. Now i'm looking onto Sony in the form of the Xperia Z2. :D
[Xperia Z1 General] dlads:
Haven't played a game, listening to music for around an hour, facebook, calls, messaging and downloading, whatsapp, LTE on all the time, some wifi.
[Xperia Z1 General] Amritttt:

[Xperia Z1 General] xplod2841:
First of all, you started from 90%, not 100 and second, you have a lot of screen on. What do you expect, miracles? Find my pictures, few posts behind, with 6.5 hours screen on. And now I'm on 58% after 1 day and 10 hours with 1h screen on time. This phone has a great battery life.

I only lost 3% in almost 9 hours (around 0,3%/h)

I have rooted today and frozen some apps and will see how it goes tonight!
[Xperia Z1 General] Jiyeon90:
how did you get root with a locked bootloader?
[Xperia Z1 General] drsoran2:
I've used "NUTs" tutorial ("Stock - Update to 4.4.2 with LB/UB and Dualrecovery") from the Z1 Android Development sub forum.

But before, I had to downgrade to a rootable 4.2.2. firmware via flashtool and with full wipe, backed up everything before with Sony Backup & Restore app.

I found the necessary file in the second post of NUTs thread, then rooted, installed dual recovery and then followed NUTs tutorial.

After that, I restored my backup and was on rooted LB 4.4.2 firmware and recovery :)

Anyone know what meadiaserver is? since I flashed nut's kitkat version, mediaserver is using 12-15% of my battery life...
[Xperia Z1 General] xplod2841:
I think that mediaserver is accessing and dealing with files. I noticed that it's mostly active when playing music. For example, if I listen to music for 5 hours, mediaserver will have cpu time around 5 hours or more.
[Xperia Z1 General] Rui Oliveira 21:

Battery seems better on KK, but sometimes it goes on a rampage ;S last night it wente down 11-14% due to phone inactivitie and radio signal....not cool!

I had my first run since updating to KitKat and only lost 2% battery over the course of 45 minutes.

Mind you, this was with GPS tracking, bluetooth pulse belt and music running all the time.

On 4.2.2, I lost 6% over the same time with the same settings, which was also pretty good already.
[Xperia Z1 General] dreamville:
Whats your screen on time? You experience any of the issues other people have on 4.4?
[Xperia Z1 General] Rui Oliveira 21:
I must say I forgot to check that out, but it wasnt much on the past few days, some facebook, insta, messaging,calling. Overhall the battery life is really better, but sometimes the "radio" consumes a lot of battery, maybe due to bad Vodafone coverage on my area.

In terms of bugs, sometimes the notification ring comes out from the earpiece, but with a reset it's ok. Nothinhg else to complain about =)

My KK is Central europe unbranded.
[Xperia Z1 General] Jiyeon90:

It was absolutely EPIC while using 4.2.2 Stock. Then 4.3 made it stay much less but it was still good that I didn't complain about it. But now, with KitKat, it is unbelievable and terrible. I'm updating my phone with .757 now. I hope it will solve the battery and heat problems. If not, I will do what I should have done even while using 4.3: to downgrade to 4.2.

I don't have screenshots but here is my usage of Z1 and its battery lifes:

4.2

:

3 days 3 hours with 24/7 open wifi or 3g, normal usage of internet.

2 days 20 hours with hardcore usage.

4.3

:

2 days 6 hours with normal usage, no auto-sync, Internet with Boat Browser, Whatsapp, Viber, Facebook etc. of course.

1 day 10 h with hardcore usage.

4.4

1 day 19 hours with low usage, no auto-sync again, only Facebook, Whatsapp, Viber, very short Chrome usage.

And my terrible experience yesterday:

I only used internet for 9GAG and Facebook for ~45 mins, did nothing special, Whatsapp and Viber again + STAMINA Mode ON. The performance: 21 HOURS!

A full day even with only those activities is good. Your screen is on a lot. But remember when you couldn't go no more than a couple hours without a charge? There is still some to spare. I bet that 17% would last all day with Only light calling & texting. Maybe a couple quick Google sessions too.
