Abysmal battery life. - Sony Xperia XZ Questions & Answers

I have run out of ideas. I have uninstalled apps, repaired the OS, done everything I can think of. The battery life of this phone is the worst I have ever experienced in a phone. I can barely get a day out of this phone (2hrs 30 SOT). I'm at my wit's end. Is it just my device or do others experience this. And does anyone have any idea what I can do?

Unfortunately Sony doesn't pack much into their batteries and software does take a toll. I had a Huawei P9 and P10 Plus and I would get a solid day of heavy use, with my XZ I can't make it to early evening with comparable usage. I prefer Sony handsets to all others, but I have to agree with you in that battery life is crap.

Yeah, but it wasn't always like this. I used the Z2 and it had great battery life and I also used a Z3 dual and it's battery life was even better. Compared to those 2, the XZ's battery life is shockingly bad. I used to get 6-7 hrs SOT on my Z3, 2 hrs is a struggle on this phone.

Check for phone idle battery drain it nukes my battery since 7.1

The phone idle battery drain has been high since 7.1 for me as well. I thought it was an app. But I uninstalled every app that might cause that, and yet...

Make sure you do a factory reset after the update.
You will thank me for it later.
Also if you want to seriously see major peeofmance and battery improvement, you need to root and installtlal duality dra4.
People are achieving 5-10hour sot with 24-48hours usage.
The experience in this rom is night and day compared to stock.
Stock ROM is complete turd.
I'm giving you this information from my first hand experience. You need this rom, else you will continue to be disappointed I know this.
Why do I know, well I've been with Sony for 5years and haven't rooted for the passed 2 years until now. It's a must to root this phone else it's merely mediocre.
However the choice is yours

+1 ...man this is all thru... i have same xperience with Sony devices...i had xperia z,z2,z5 and now xz and since z5 everything is going down...less battery life...same speakers since z2...very bad loudspeaker its so low that even a low budget phone beats it.. also OVERHEATING badlly...but the design of the phone is way better then any competition atleast for me...and also xz is very durbale phone it fellt 5 times already on concrete also 2 times fell directly on the screen and nothing is broken yet...screen has only 2 little scratches and of course all corners are beaten up a little bit hehehe over all very durable trust me...this new plastic that they use is so good...and at the end i really must say that rootin is a must for this phone cuz since i got it i had constant problems with stock rom, specialy with ram usage it gave me lags all the time but now i use custom rom and xz is flying like it should.

Install wakelock detector or betterbatterystats and check what's draining your battery. This phone should easily achieve 1 day battery life. I'm getting 3,5-4 of Ingress (AR game that uses GPS+Mobile Data+screen on - so it's hard to drain more)m and about 5sot with normal use

G2x Battery Life?

What is it like?
For now is 2 short
Waiting to see this myself, but truth be told, I had horrible battery life on my other Android phones, G1 and Nexus One
My nexus s has great battery life
Nexus S
I'm sure we wont know for a week or two because the batteries take some time to get used to cycling . I hear the o2x gets a day-a day and a half and they have stupid lg bloat processes in the background as well as crappy email services
I think it will take 1-2 weeks before we can fully test how long battery life is. Initial battery life out of the box is expected to be bad. We will need some charge-discharge cycle first to fully calibrate the phone's battery.
I expect batt life to be bit better on g2x than stock O2x cause it has less bloatwares and it is running on stock android froyo.

I am quite impressed with the battery life so far, and coming from a Nexus S that says a lot. I'm going on 14.5hrs my first day of full use (light to moderate, I was working all day) and have 23% left. I wish it had 2.3 so I could post a graph for you...oh well.

I use titanium to freeze bloatware. I did not delete them to allow OTA updates - if ever 2.3 or 2.4 show up.
It very depend how u use your mobile, if I dont play games at all just call and text plus some weather updates trought wi fi or gsm, phone hold for me up to 3 days, but is very hard to dont play games on it (phone not rooted,standart lg soft 10b)

mission complete. i laughed lol
Just ordered mine
I hope its better then my Nexous one (last all day easy)
Second full day of usage on my G2x. It did not make it though the whole day. It is miles ahead of the Nexus One, and EVO (which was garbage). However, it definitely cannot compete with the Nexus S in this department. Only time will tell how much is hardware and how much is 2.3.3.
I have a feeling most of it is software. On my G2x the majority of the battery is consumed by Cell standby and Phone idle, as with all other pre 2.3 devices I have used. With my Nexus S the Cell standby and Phone idle use much less battery which I would assume is attributed to software improvements. The display uses most of the battery (and the display is very efficient since gingerbread has a dark interface with the NS samoled)
I don't have specific numbers handy but would be more than happy to post some if anyone is interested.

What's the proper way to do this? No instructions out of the box...
The first two days, the batter life was horrible. Once the battery dies, and was charged a couple of times it got better. I also used setcpu to underclock which probably helped a little.

I did not know this. How does not having some apps prevent OTAs?
while using set cpu is anyone having a issue trying to select the scaling governor? its not highlighted on my g2x so i could put it on demand!

New phone battery life

Hi!
I am new to the nexus 5 community and I just got my nexus 5 about 2 days ago
After fully charging it I started using it , I have heard that nexus 5 has battery issues and that's why I only want you people to help me tell how the battery life of my phone is for a brand new device by seeing the screenshots of my usage.
Here are the screenshots:
Looks normal to me. What's ingress? A game?

Not bad. I would disable Wi-Fi always scanning available (even if Wi-Fi is off), location to start. That's not bad though and is about what I get, but you might be able to get better SOT.
the nexus 5 does not have battery issues, at all. it stupid people that themselves have issues, not the phone.
Seems normal to me ,I bought mine month ago
There are no issues with battery on nexus 5. I charge mine usually once in 3 days, my record without charge is about a week.
It really depends on how you use it. Under constant 100% load I think battery can be depleted under 5 hours, as in every other device.
i can use my phone very heavily, and deplete my battery in 6-8 hours. but ill still get 5+ hours screen on time.

Have you tried running the phone down till it switches off? I know it's not good practice to do that often but I like to do it with a new phone relatively early as it makes sure it's calibrated - sometimes phones can either switch off at 5% or, conversely, run on 1% for hours...

You don't ever need to do that as it calibrates every time you charge the phone. Also he just got the phone and isn't having any battery issues.

He means to break in a LIon battery the first three times you kill the battery and then don't take it below 20% after that.

That's not helpful and does more harm than good. Li-Po never needs to be user calibrated in any way.
Thanks!
Thanks a lot guys for taking your time and helping me , nexus 5 is truly an amazing phone.
@Ben36 yes , ingress is a game and its a location based so it keeps running in the background and uses location services.
Guys , I have some questions relating to the vibration motor , is it fine if I ask here or am I supposed to make a new thread?
Thaks a lot once again

I was just about to start a thread about something then I read this. So here's the deal. I agree that it's almost always user error and/or over expectation when it comes to battery. Stupid people are here to stay. I'm neither stupid nor expecting too much from my battery.
I've always been intrigued by how some experienced users get great battery and some get not so great. Has to be user error I always thought. I thought this because I was one of the experienced users getting great battery life. I mean GREAT. Way over 7 SOT all the time.
So a few weeks ago my first phone had an audio port issue that I had RMA'd. I received the new phone and set it up. It had crap battery. I'm talking less then 2 hours SOT. Same ROM, same kernel, same apps, same coverage for mobile and data, same usage. I set about looking for wakelocks and they all where the same as the first phone. Nothing was wrong on my end. I spent over a week troubleshooting. CPU frequencies and time in state where normal. Temps where normal. CPU benching was the same. Awake vs screen on was almost identical. The phone is sleeping like a baby when not in use.
So, using Occam"s razor, it would lead me to believe that not all batteries in the N5 are created equal. After getting off the phone with a google support supervisor a few hours ago he agreed. Another RMA process has been set up and I was promised this phone would make it's way back to LG so they can actually analyze the battery.
Like I said, I used to think the same way you do. Now I'm not so sure.

oh, no, I 100% agree with you. just like our devices, that all aren't equal, that are all assembled in differing places, that all have smaller parts that are made in more different factories.. the batteries themselves will differ as well. it'll even probably fall onto a bell curve, where most are near the center, and less with better or worse. but 100% they vary.

Well I feel that there are always some exceptions , some phones may have a manufacturing defect and maybe the phone you are talking about did have one , but these manufacturing defects are mostly really rare.

I was just explaining what he said. The rumor is (supposedly backed up) that you kill the battery 3 times in a row but never take it close to dying after that and you get the best battery life possible because the battery works best if you only charge it between 20 and 80%. I think there may be something to it because new phones only last like half a day on the first charge but after a week last a day or longer for me. I won't derail this thread though as that's a debate that always loves to go on and I've never found hard proof either way but people who just write websites who supposedly sound smart and can word it quite eloquently.
That being said, I didn't necessarily agree with it, but I was clarifying what was said.

Thanks for clarifying. Keeping the battery between 20% and 80% is said to help with battery degradation, which after a year or two might affect how much one could get out of a full charge. Most won't find it practical to limit them self to only 60% of their total available battery pool though.
Even hitting 0% isn't as big of a problem as some may think as there is a reserve charge for protection. For instance, mine has full died on me twice due to a power outage (I even attempted a boot up) and I always full charge with no noticeable degradation after 8 months.

Huge battery drain !!

I am facing a huge battery drain while on standby in my Xperia XA. .
Its draining around 35% - 45% overnight doing nothing! Anyone else having the same issue ?

Is stamina mode on and set up properly, is background data disabled. Auto sync, location in GPS instead of battery saving ect are all things that will drain battery try doing a factory reset or software repair both can work wonders when you have problems. It's more likely one or a combination of the above and to much running in the background

Tried factory reset and checked all of the above settings things seem a bit better now. Meanwhile checked in Sony forums, there seems to be a WiFi bug which is causing this. Someone from Sony has also acknowledged this. Hopefully this will be resolved in a software update.

Yeah I Saw that gonna be fixed in a update, wifi always scanning needs to be turned off till then, how are you finding the xa apart from that seriously looking at replacing my M2 with one in a couple of weeks I just hope it doesn't get left behind being a mediatek powered Xperia if I get one.

The overall performance is above average given the near stock Xperia UI. Maybe its not as good as SD 650, 615 series, but it still is manageable. Few sour points like free space is very less, 2GB RAM(but RAM management is pretty good), battery life and lots of bloat in my region atleast. The camera and the display are the plus points. Even though it has a 720p, colours are more vivid and sharper than most phones. The brightness levels too can move from very low to very bright.The design feels premium too with the edge to edge screen. Finding a tempered glass to cover the entire screen edge to edge is bit difficult though. I would suggest go for XA Ultra if possible.

My network only do the x,xa,m4,z5,z5c and z3 i was going to get the x but even on a contract they want to much a month and expect me to pay towards the device(not gonna happen) which leaves the xa as this would be a free device or a honour 7 also free which looks good but I don't like the ui and no app drawer and the xa spanks it in antutu benchmarks and I'm a Sony fan anyway just gonna take some getting used to not having root as I refuse to unlock the Bootloader on a Xperia device and lose all the things you buy a Xperia for to root it. Next two weeks can't go fast enough

Agreed. Its best to stay away from Honor. Here in my country XA Ultra is not even available and Xperia X with inferior specs is more expensive than the Z5. Certainly this is what's wrong with them. They are talking about de-focusing from certain markets. Don't really know where their focus is. Hope they get things sorted out. Their design is just so good. Its so ironical.
I wait for an update to fix the problem !

Yes I have already done this. WiFi is still draining the battery but it's weird the battery is getting better day by day.
Its lasting for more than 24hrs with moderate use now with around 4hours of SOT. The only difference was that I have inserted sim cards. Previously there were no sim cards. Could that be the reason behind the drain?

It probably didn't help the situation having no sim card inserted. The more you use it and charge and discharge the battery the better it will get it may take a week or could take a few weeks to reach its maximum screen time ect. 4hrs sot ain't to bad for a device twice as powerful as the m2 with the same size battery more or less. I usually get between 4.5-6hrs sot depending on how I use it on my m2 I'll be expecting at least 4hrs sot when I get mine on a stock device that is. More than that on a rooted device if root is available that is. I looking forward to getting this device to be honest even if it is a mediatek powered Xperia

Yes the battery has settled after a couple of discharge and charging cycles. :good:
Yet the whole threat is useless.You cant change how the battery / OS is acting, WITHOUT unlock and root access even new custom rom.I lost like 2-3 days in searching for solution of my problem , to find working guide to unlck the bootloader.
The only possible method to save your battery is by using GREENIFY. Using it on my htc phone for like 3 years, with personal score of 30+ days without recharge (STANDBY). Greenify works on root device, that cant happen on this phone ,yet.
PS: i've used some tools like - http://developer.sonymobile.com/unlockbootloader/imei-verification/1d2ac140b78501316d82b5e787350b76/, Flashtool, without luck.

If this device has drm-verity which i do believe all new Xperia device's have since z3+/z5 locked Bootloader root will not be possible unfortunately. I'll know abit more when I get mine next week hop, my current M2 device is heavily modified but it doesn't look good for locked Bootloader root from now on.
I am starting to think that there are some other issues here other than wifi. I think the phone struggles to hold/find signal as my cell standby usage seems really high to me. I've noticed that when at home and the phone is on wifi my battery seems to last for ages. Its the second highest user over the screen.

My battery hardly reaches 3 hours onscreen, normally just more than 2 hours with very little usage, just facebook and around 15 minutes of boom beach over wifi. Even when I've already turned off the wifi scanning it still drains a lot idling. So I don't think turning off wifi scanning is the proper solution to this at all.
And yeah I think hpsauce37 has a point since I've been experiencing really weak mobile signal that leads to disconnecting my call automatically sometimes. And the mobile signal indicator just stands there at 2 bars at the same spot where my Xperia P shows a full bar.

U got 2 options to dissable WIFI scan.Look at the settings.
just to share, by disabling scanning wifi the device still scans for wifi when i switched off the wifi (i know it is a bug. im running build .35)
however, i have reduced the battery drain by 30%
-uninstall facebook (which is 99% running in the background)
-activate stamina mode (always on)
-switch off location service

Why is the phone so laggy?

So, I've noticed that phone can be a bit laggy. I first noticed it before the Nougat update, but after the update it's even worse. The phone stutters and lags a lot, and it's really annoying. And the battery life is mediocre to be honest. I'm coming from a Z3, which was basically a perfect phone, so this is honestly quite disappointing. Is there anything I can do to fix this?
Have you tried doing a factory reset?
Do a factory reset. Better yet use flaahtool to better wipe all partitions to clear any remnants of previous installation.
I can attest to the fact that over several of my previous sony devices that post OTA installations deemed my phone's sluggish.
This doesn't seem to be the case for everybody, however for me at least a clean fresh install via flashtool did the trick for me.
However... I feel that the phone is slightly sluggish on nougat compared to MM specifically when interacting with the device on wake up.
It's not as lightning quick to keep up with my interactions as well as MM was.
Placebo perhaps, but my XZ certainly seems to be a tad slower then MM was from my experience.
I'll try a factory reset and see if it helps. I didn't want to do one, but I guess I don't have much of a choice. Thanks.
Try a repair by xperia companion. Best reset for Xperia
I have that lags too..
I tried to factory reset and it didn't help, I didn't try to do xperia repair because earlier i changed my rom to romaur v4.1 and i afraid of brick my XZ..
does anyone found a way to make this phone faster?
And what about the battery life? The battery life of this phone is shockingly bad. I didn't expect it to be as good as my Z3, but this is just terrible.

The least batt life I get is 4 to 5hrs SoT but the highest SoT I got is more than 11hrs (text, a little use of mobile data, movie/video viewing, reading Wattpad, camera, bit of game/s). It all depends on the usage.

Are we using the same phone. I can't get over 3 hrs SOT, no matter how I use the phone. It's so bad.

Sounds like a misbehaving app. You should easily be able to get 6-8+ hours screen on just by turning the brightness down some, if there's no app hogging all the power.
It probably is. Because GSAM shows that most of my battery is being drained by apps (about 70%), particularly Android OS and Kernel and the in built battery monitor puts 'phone idle', even above the display. I just can't figure out what it is.
Maybe you had bad luck and got a bad battery in your phone. It can happen, especially since you say Idle is at the top. you should get a longer time than 3 hours if Idle is at the top
My USA and docomo Japan versions of XZ both get incredible battery life with zero lag.

Yeah, but that doesn't necessarily explain why the app usage is so damn high, even at 2hrs plus of screen on time, it still accounts for about 70%.

I can vouch for the DoCoMo XZ version. That phone uses 1.5gb of RAM due to two default launchers, DoCoMo launcher being the hog even after disabling most DoCoMo services.
Check your SD card as it could also drain your phone on idle. That matter has been discussed.
I'm currently using the phone without the SD Card, uninstalled FB messenger and with Bluetooth off (normally connected to my smartband), while there has been a modest improvement, it's still quite high, especially compared to my Z3. The orange themed GSam screenshot is from my XZ, while the green themed one is from my Z3. App usage is significantly lower on the Z3, with the screen using most of the power, which is supposed to be the norm.

Trust me, it is.
My phone is also sometimes laggy...
I installed Arrow Launcher (from Microsoft) and now its butter smooth (60fps).
Maybe, there are some problems with Xperia home launcher.
Nova launcher is also better, but sometimes also little stutter.
Apps are running ok. Sometimes little stutter...

battery has become utter trash since 8.1 update

anyone else notice it? first off, I'd be at like 40 minutes screen on time before I'd drop to 99 percent... now, it drops immediately after unplugging, and that 40 min screen on time, I'll be at like 69 percent now. it's absolutely ridiculous. battery drains like crazy now, but nothing is running in the background that shouldn't be. everything is identical to pre 8.1 update. today I was at right under 60 min screen on time, at like 59 percent. I looked at old screenshots pre 8.1, and I'd be at like 2.5 hours screen on time at 59 percent. it's absolutely ridiculous that Google is purposely ruining the phone with each update in terms of battery life. I'm not the only one, either. it's on reddit as well. planned obsolescence? yep, I'm starting to think so.

Man. Do you live off grid or something and can only charge every 2 days or something. If you want 3+ hours of SOT than you would have to be close to a charger anyways and that's with any phone. All these phones that have come out late 2016 early 2017 have the same battery set up...use your phone and charge it fast and use your phone some more.
My pixel 2 same as my Moto z2 force and my s8

I really doubt it's any different than it was. It's more likely the battery wasn't reporting correctly in 8.0. When I was on 8.0 the battery would sit at 100% for at least an hour, maybe 2, all the while I was using the phone. Yes, since 8.1 it drops much faster when I first start using it after removing it from the charger but at the end of the day I still have pretty much the same battery percentage left as I did when I was on 8.0. It drops faster to begin with but in the end, it's the same as before. Rather than planned obsolescence, it's more likely they simply fixed something that wasn't working properly before. There's no way you can use one of these things for an hour or more and not have the battery drop below 100%. Just my two cents worth.
Can't complain. Forgot twice to plug it in at night, woke up both times with 45% left. At my regular use that is good. My previous S7 would have been down to <20%. BTW, this:

is just utter BS, maybe you should reinforce you aluminum hat...
I can't say my battery life has been bad or gotten worse with 8.1. If anything it got better. I didn't plug mine in last night, woke up with 38% left. That was about 20 hours since last charge. I don't think Google is purposely obsoleting their newest phones a couple months after release either.....
Edit: I should mention, I have my AOD always on, I have Now Playing enabled, double-tap-to wake is disabled, and I use one of the prepackaged Pixel 2 live wallpapers (Marvelous Marble). The only ting I really do thinking of the battery is turn the phone face down when I go to bed since that shuts off the display.
so i guess the fact that my screen on time has dropped by over an hour means I'm the one who's crazy, and the phone is perfectly fine.... riiiiiggghht.

I'm pretty sure this part of your post is the crazy part. Your battery drain is probably real. Have you confirmed it exists on a clean install without any apps installed or system configurations changed? Only then should you entertain that this is Google's fault. Even then, accusing them of doing it on purpose runs dangerously close to tinfoil hat territory.
I feel my battery life has gone down slightly going from 8.0 to 8.1. Though, I'm running all the bells and whistles this phone has to offer, along with tasker profiles. I also agree with the previous statement. Perhaps the system wasn't accurately measuring the battery life.
I did have horrible battery life for a bit when I was playing with a new kernel and dirty flashing some things to get Viper4Android working.
I have two Pixel 2 phones (non XL), and honestly they are amazing at battery compared to my HTC M8s (again two) . Are they perfect? No. Are they better than any phone I've ever had? Yes.

As has been said above, the battery no longer sticks at 100% for the first hour or so of screen on time, but that was always obviously nonsense anyway so a fair conclusion is that it's now better calibrated. But I've noticed no difference overall in battery life: yesterday was the first time I tried running for 2 days rather than charging overnight, and when I plugged it at night it had run for 41 hours with 6 and a quarter hours screen on and 7% remaining, so really not a problem there.
If you're having trouble with an update:
- Use BetterBatteryStats to figure out if any apps are acting up (or just top off the battery, use phone normally, and check Google's battery stats for Apps Using Battery, standby drain and screen on time)
- Clean flash the factory image, set up phone as new, go through charge cycle and check stats.
I'm not having any issues with battery on 8.1 (clean installed factory image). Easily get 4 - 6 hours SOT. As a matter of fact, my battery life is shockingly excellent for a smaller device like this.
Google is not making battery worse on purpose with their brand new flagship device.
I don't have any issues with the battery after the 8.1 update. It doesn't stay on 100% for a long time like it used to, but like everyone else is saying, that must have been buggy before. It isn't realistic for the battery to stick on 100% with 40 mins of SOT. Overall I don't see a reduction in battery life and I'm quite happy with the 8.1 update.
I was checking BBS and couldn't tell much. Do you still need to install it as a system app?

Not sure. I haven't used it for quite a while. The built in battery info works well enough for me, I haven't been having issues. It's good for checking wakelocks and some more advanced stuff but I think it needs a few cycles/days before it can analyze properly.
I think it's just the way oreo is. Ever since 8.0 it just drains the battery very aggressively. 8.1 the OS runs smoother, but battery drain is still high. Been the case though since 8.0 for me, nothing new.
I haven't clean flashed in over 6 months though. Just been on 7.1 and been rolling up the OTAs and chugging along. I found using Naptime by Franco helps a bit.

IMO battery life has never been great on the Pixel 2. It's the same on 8.1 as it was on 8.0 for me.
Right now I'm trending towards 6 hours SOT (3 hrs SOT at 50%), and I have been BT streaming audiobooks most of the day. I also watched Netflix for 30 min on full brighness. That's better than 8.0 for me, I was lucky to get 5 hrs SOT max.
I would say the calibration is more accurate now, it hung on 100% for too long, so it may appear to drain faster but so far in practice I've gained battery.
Battery life isn't as good as my OP5, but that has a big battery compared to the Pixel 2. I think for it's size it's doing a good job.

I guess you are talking about one of your other devices here, rather than the Pixel 2.
I am getting horrible battery life since going to 8.1
I installed the update the night of the 13th. The past 2 days my battery drains to 20% in about 8 hours. At that point whatever is causing it was stopped by the battery saver mode or the reboot I did when I discovered the phone was in battery saver mode.
Light use at work, staring at my phone is not a thing I have time for. No streaming, no surfing. Just checking texts and emails here and there. Prior to the update I'd get home 12 hours after I left the house and be around 75-80%. Not rooted, not unlocked. Bone stock.
Built in battery stats say 'system' is the culprit. Digging deeper I see Google Play Services app used 70% of my battery from about 7am to around 4 or 5pm this evening. I'd post a screen shot but I didn't to think of taking one before I plugged it in. I just installed BBS and will monitor it for a day.
