I presume you've done this in same conditions? :) Do you have apps like FB, Messenger, Viber, Whatsapp installed?

My phone came with 5.0.2 so i didn't try out 4.4.4, but I had pretty good battery life on 5.0.2, and for couple days on 5.1.1 as well, but all of a sudden drain appeared under same usage. My biggest suspicion are those stupid Play Services updates, its a hit or miss. There are 352 services running under Play Services and my question is WHY? Majority of those are not necessary for average user (not on daily basis at least).

Can you try out for a week to see if there is consistency on 4.4.4? On 5.1.1 battery life seems good on one charge, and on next it goes bad.
[Xperia Z3 Compact General] paulmt123:
That was the biggest problem I had with 5.1 also. Intermittent battery loss. Sometimes OK, othertimes large drain on standby.

On kitkat I'm running up pedometer, Facebook, Sony email instead of Gmail and synced up to Gmail. And I'm syncing everything to a smart watch with Bluetooth on all day. After unplugging at 7.30am I'm now on 80 percent with 47 mins screen on time. That seems good to me. That gets me about 5 to 6 hours screen on time per day though never usually use that and end up with about 40 to 50 percent left each night.
[Xperia Z3 Compact General] PuffDaddy_d:
I finally just gave up on LP and reverted back to KK. 4.4.4 just works better. I don't have to babysit google apps to make sure nothing is draining the battery. I honestly don't care how much battery drains overnight, but I do care about how much drains while it sits at my desk at work. Losing 20% in 8 hours of absolute minimal usage (checking the time or responding to 1 or 2 text messages) is unacceptable.
[Xperia Z3 Compact General] paulmt123:
I'm thinking the same. Even with Bluetooth syncing to smart watch, a pedometer measuring my steps and nearly an hour of screen on time I arrive back home on kitkat with 80 percent left. With lollipop it's more like 65 percent. More of a problem on a weekend when I use my phone more. Can exhaust it in one day on lollipop whereas I'm outside the low battery warning on kitkat. I'm disappointed as I hoped lollipop would be more efficient. In benchmark tests it has been. But not with my usage. Sony hasn't been great with updates in the past. My SmartWatch voice function now doesn't work and it's battery life is much worse, only just over a day instead of 2 since that got updated despite factory reset. And my old Xperia sp was rubbish after its update to 4.3. Mind it doesn't seem Sony is alone. Samsung users also have issues. Galaxy s5 battery life on lollipop is an issue. It might be that some apps like Google play services aren't yet optimised for the new build?
[Xperia Z3 Compact General] novahob:
Turn off mobile data and have wifi on with it turning off when phone asleep and I'm same battery life as on KK. So to me it proves something is wrong when the phone has access to the Internet all the while with mobile data. Also now google play services isn't near the top of my battery usage and screen is now like in KK. Just my opinion :)

[Xperia Z3 Compact General] km8j:
For me, standby time is fine but I'm having issues during usage. I.e., say 5 hours off the charger with 1 hour of screen time and I'm down slightly more than 20%, which is less than 5 hours SOT. Definitely remember being able to cross 6 hours on KK. I have stamina mode on just restricting performance to see if that helps and also have stuff greenified but I don't seem to have wakelock issues. Any ideas?
[Xperia Z3 Compact General] Metall Boy:
Here is my usage. I still get two days, with light usage, stamina off, wifi always on. Automatic sync is on for all my accounts. Location is set in device only. Its not great battery life, but its enough for me. I really like sonys take on lollipop I think they done a good job. If only they could match the battery life in kitkat with lollipop.... That would make me very happy :)
[Xperia Z3 Compact General] Cirra92:
I gave up on LP as well, and I'm back on latest KK, which is .77 (for the first time, since I bought the Z3c with 5.0.2) and I'll say it's been a great move. No weird battery drain, very fast and smooth, and for the most important part, I feel the consistency in battery life. Brightness around 40%, location off, sync off, most of the SOT was on FB, Messenger, Instagram, Whatsapp and Viber (constantly running in background) since I use those apps on daily basis. Wifi/3g used only with screen on (note that Stamina was actually off). And Stamina mode works on KK, as in LP (there were reports from others users too) it actually behaved like it wasn't on.

As someone posted before me, BBS was not reporting significant drain on LP, but battery percentage was dropping slowly, and screen seemed to use more power than on KK, so once I ended up with 6h of SOT (not more surely) and maybe 15h of total time, which isn't generally bad, but for this device it is.

GPlay Services are playing major role, but my personal opinion is that it seems lot of apps aren't quite optimized for LP, and it may as well be that Sony's 5.1.1 kernel needs a bit more tweaking.
[Xperia Z3 Compact General] paulmt123:
Battery life on kitkat seems hugely affected by Google fit. Reckon that's knocked at least 20 percent off my daily battery life since activating it. If lollipop has this running by default this could be one reason. I wonder what else lollipop has running by default.
[Xperia Z3 Compact General] Cirra92:
Well, I can't replicate that, since I'm not using it at all on both KK and LP. As a matter of fact I disable services related to fit/wearables right away.

Although I tried to disable as much services and apps as I could on LP, that included greenifying all those social apps that I was using, + some more, I didn't achieve anything impressive on 5.0.2 nor 5.1.1, at least not consistently. I posted some good results here, but it was once on both 5.0.2 and 5.1.1, right after clean flash. Didn't greenify anything in KK, and it does better job :confused:

I'm guessing lack of good app optimization on LP, and some weird background apps/services/processes management, which caused random drain, still don't understand why, as LP is supposed to be more efficient :rolleyes:
[Xperia Z3 Compact General] jarayn:
Mines almost exactly the same on kk and lp.

About 6 or so hours sot. I've never seen anything like 8 plus. But then I don't see the point of turning off everything just to get more hours.
[Xperia Z3 Compact General] Velocy:
I was worried when a saw some people saying that the 5.1.1 was grabage on the battery side, i can still acheive a 5h+ of SOT in two days of medium/heavy usage .....for me it's kinda good.

But there is sooooooo much services i would like to shut ! i'm sure i could gain a solid 1hour more of SOT, rooting is more and more .......seductive

[Xperia Z3 Compact General] gohar3909:
Sorry, a bit off topic, but here are my battery stats for an year old Z3C running on KitKat 4.4.4(Stock).
[Xperia Z3 Compact General] paulmt123:
My smartwatch was misbehaving with my phone on kitkat so upgraded back to 5.1.1 on Saturday.

Last night I was rudely awakened 5 times between 5 and 7am with vibrating notifications despite being on stamina mode with no data when screen off and on silent mode. I then disabled WiFi and data and still got more. Not impressed. Worse still screen on time on gsam battery monitor is down to under 3 hours on average vs 5 for kitkat. Without Bluetooth smartwatch kitkat was over 6. But even with watch syncing I got 5.

It didn't fix the smartwatch either. Itself malfunctioning on 5.1 android wear. Went flat in 5 hours today and nearly burned my wrist.

So it's back to kitkat for me and my smartwatch is just a watch that tells the time and sometimes displays notifications. Wish I could also downgrade that to kitkat. Now I must put reminders up on the wall saying don't try and upgrade to lollipop again!! I keep thinking it'll fix any issues I have with compatible devices only for it to make things much worse. The watch may have to go back for repairs. I've factory reset it lots to no avail. Still feels like software fault though. Will have to see if I can reinstall android on it. If you have battery issues downgrade to kitkat. Likely will solve them. Doesn't look as good but you get a more reliable device which lasts a lot longer on standby and during use. No need to greenify or turn off data and WiFi. Just lasts without hassle. And no waking me up at 5am either!!

Chrome on kitkat is also much smoother. Even on this site. The keyboard works better. Sony needs to sort lollipop out. Seems some have no issues. Some have big issues. I guess it depends on how you use your phone. I know 3 others with Xperia z3 compact running 5.1.1. One has no issues, one has a few glitches and the other has a very unreliable phone that often plays up. All 4 worked perfectly on kitkat and 2 perfectly on 5.0.2.
[Xperia Z3 Compact General] jarayn:
Which bit of that wall of text rant is about battery life?
[Xperia Z3 Compact General] paulmt123:
Sorry. Went off topic somewhat. Back to battery life. 5.1 is unpredictable. With 4 different phones. More unpredictable than 5.0.2. Which was at least consistent. You get occasions when battery drops rapidly for no obvious reason. Other times its fine. Usually when on standby. The phone also gets hot when this happens. It's so bad my friends compact is now broken due to heat damage. Won't even switch on. My wife's is randomly calling people and crashing with poor battery life. My other friend lost 20 percent in one hour this morning not even using it. Meanwhile mine is working brilliantly as it's back on 4.4.4 kitkat until Sony/Google sorts out lollipop. Battery life with Bluetooth on drops at 1.5 percent per hour. I'd love to keep lollipop as it looks good and is more likely to be supported in future but I can't get consistent battery life on standby. Final sum up. Lollipop battery life is worse than kitkat. About twice as bad when not using it and slightly worse when using it too.
[Xperia Z3 Compact General] Dark Emotion:
Is it hard to downgrade to kitkat? I just got the phone few days ago and I can already see the unpredictable battery life

P.S. "Sony" cannot fix lollipop because they didn't breake it, Google did. I come from Nexus 4 which runs pure android and it's the same thing, maybe even worse, Sony did what they could do
[Xperia Z3 Compact General] PuffDaddy_d:
Your experiences have been similar to what others are seeing too. I went back to KitKat for the exact same reasons. As I've probably said too many times already, my battery life on KitKat is double what it was on Lollipop. If the Z3C's battery life wasn't naturally so amazing, I think more people would be complaining about it, but so many have never experienced KK battery life, so they can only compare it to their old phones.
[Xperia Z3 Compact General] paulmt123:
It's not that difficult. If you search for downgrade to kitkat or manually upgrade firmware in Google or on here you'll get a guide saying how to do it. Once you've got the software and firmware kitkat version it's easy. It doesn't invalidate warranty either. You need to enable USB debugging on phone for it to work.
[Xperia Z3 Compact General] jarayn:
Your battery life wasn't double on kk.

It might have been better, although that's not my experience but hyperbole doesn't help.
[Xperia Z3 Compact General] PuffDaddy_d:
I wasn't trying to be hyperbolic, but with that stupid mobile radio active bug in LP, my phone would dip to 50% battery life at the end of a typical work day. With KK, I usually end the day with 75% battery life remaining. 50% drain is twice as much as 25%. Therefore, the battery life has doubled for me. What other way should I say it?

Mobile radio active bug can be fixed via xposed module.
[Xperia Z3 Compact General] PuffDaddy_d:
Yes, but that thread has 6 pages of mixed results and shows a number of cases where it only modified the battery reporting stats but the actual battery life didn't improve. I'm not ready to call it a fix just yet. Have you actually tried it before recommending it to others? If so, how much improvement did you see?
[Xperia Z3 Compact General] novahob:
Tried this on Z3C, standard so no root or unlocked bootloader. After leaving mobile data on overnight and checking Google play services's before and after mobile radio active usage it hasn't worked :( phone used 9% battery overnight with the radio active on for google play services being nearly 2h 30m.

So after getting a reply on the other thread this doesn't work without root etc :(

There's seems to be 2 issues with wakelocks with 5.1.1. The first causes a constant light battery drain as the phone can't sleep. Annoying. The second causes the phone to heat up and use full cpu usage. That causes rapid unexpected battery drain. It's this one I'm most concerned about as the phone doesn't seem to cope well with constant heat. My friends failed after doing this and I've just removed case and found the back of mine has cracked at some point. My other friends lost 30 percent battery in an hour and downloaded 1 gigabyte of data. In all the cases it seems Google play services is the culprit. Even on kitkat I still regularly get that coming up as the main offender. Also true is not many complain as 4 hours screen on time is better than many smartphones. But when you used to get 6 and now get 4 you're less forgiving. I can have Bluetooth to smart watch, constant syncs and data on all the time in kitkat and match what I got in lollipop with nothing on. With all that on I couldn't make it through a day without charging with 5.1.1.

Seems a problem with multiple devices. Hopefully an update to Google play services will make it safe to upgrade again. Key reason to upgrade is you can move apps to Sd. However. Somewhat strangely even after doing this on Lp I have less space than with kitkat with no apps moved. So maybe that doesn't work properly either. Uninstalling Facebook didn't help much. Hopefully we'll get android M. Lp wasn't quite the step forward I hoped. Does anyone know what Google play services is doing to use so much data and battery life?

---------- Post added at 01:52 PM ---------- Previous post was at 01:41 PM ----------

If battery life is a problem definitely consider downgrading to kitkat. Doesn't look as good and no apps to sd but otherwise works exactly the same. Phone runs cooler too which should help it's longevity. No issues with wakelocks apart from Google play services and even that is not very severe. But you'll only have 11gb space for apps maximum and that's it.
[Xperia Z3 Compact General] PuffDaddy_d:
Agreed x1 million
[Xperia Z3 Compact General] paulmt123:
Its nice Sony gives you option to downgrade. HTC certainly didn't with the one. An update ruined my signal and no way to fix it. My tablet has no way to downgrade either. But you can put any firmware version you like on z3 compact. Lose all your data and messages so back up first. It's nice we have the option of more modern design or better battery life. Maybe android M will give us both.

I was first on 5.0.2 with stock debloated rom.battery life was so-so.

Updated to 5.1.1 and it's not good at all.I get about 7 hours Screen on with 30 Percent screen Brightness.

Downgraded to KitKat 4.4.4 and it's a lot better.Switched to Miui 7 and i have to say it is Amazing on battery life but has some graphic issues that are not much important.

So if u want battery Use 4.4.4 and Miui Roms.;)
[Xperia Z3 Compact General] jarayn:
lol. its people like you that make everyone think they have some problem when they dont.

You complain about 7 hours sot? "not goot at all" you say. Wtf. How much do you expect?
[Xperia Z3 Compact General] novahob:
I got between 6 hr and 7 hr SOT with KK regularly with everything turned on. LP isn't as good but that's because of the mobile radio active bug. If this was sorted LP I'm pretty sure would be at KK SOT standards. So I turn off mobile data when not needed and bingo I'm back to 6 hr SOT. Yep, it's not ideal but good enough for me

[Xperia Z3 Compact General] paulmt123:
Much as I like kikats stable battery life it feels just a bit dated and also has security holes that are fixed on Sonys lollipop latest update. So I've upgraded but this time all the way to latest build (3 stages) before factory resetting. In the past I've only factory reset after 5.0.2 then done last upgrade to 5.1.1 without reset. I'll let you know if this turns out better. After upgrade I was on 42 percent. Now after an hour I'm down to just 5 percent but phone has been constantly reinstalling apps. It feels worryingly hot though.
[Xperia Z3 Compact General] PuffDaddy_d:
Good luck, but the method of upgrading isn't the issue. It's the mobile radio active bug. It affects some more than others, but it's typically only there in lollipop. Textra is my messaging app of choice and it applied the security fix for KitKat 2 weeks before Sony could for LP.
[Xperia Z3 Compact General] romcio47:
I have Z3C for more than two weeks now. Since the very first start, I was using 5.1.1 (CE1) and I must say that I was amazed about the amount of time it took me to drop the battery from 100% to almost 0%... I got used to my good old Xperia T where it was hard NOT to charge this phone at least twice a day because of my sometimes really heavy usage so a phone with huge battery and incredible battery life was a must and I decided to buy this phone. I'm really happy, Z3C + Lollipop made me forgot about taking my standard set while leaving home: a phone together with a powerbank. But it wasn't enough for me, Sony promised up to two days of battery life and I was hardly getting 1,5 day even with standard usage - SMS, 2-3hrs of calls, some facebook + messenger, photos... and also I had STAMINA backed up by my old friend - Greenify (Xposed was installed too). But still I was getting 1,5 days... I thought "Hey, but what's with that Project Volta thing? Shouldn't it boost the battery life?". I'm that kind of a curious guy...

So I decided to flash Kitkat and... I forgot how the charger looks like. Battery life is OUTSTANDING. From the very first full charge, with the same set of apps, STAMINA on and NO GREENIFY I got 3,5 days of usage. Freaking 3,5 days with normal, almost the same usage, even heavier than on Lollipop sometimes... I stayed with Kitkat. I like Lollipop but the phone I can rely on is more important than the functions I lose because of the downgrade from 5.1.1 to 4.4.4. So my advice is - don't be afraid of downgrading the software if you really want to have incredible battery life on your Z3C!

Now I'm waiting for Marshmallow. If the battery is at least a half that good they promise to be, I would finally update but now I'm staying with my incredible Xperia Z3 Compact on Kitkat. Respect to Sony for creating this amazing phone :)

So kitkat works fine. Excellent battery life.

What is the difference with lollipop that causes so much drain on standby?

I've heard it's mobile radio active bug. Anyone got a fix for this that actually works, ie. Gives around only 1 percent per hour battery drain in normal mode with data on as per kitkat.

And do you need to be routed?

Any fix without routing? Some of my apps won't run if phone is routed.

Will android M fix this problem?

I'll stick with kitkat until there's a definite fix. Like apps to sd and more modern feel of lollipop but worse battery life (although still better than previous phones) and a hotter feeling phone (warm even on standby) means will stick with kitkat. The last post showed very good drain on lollipop. How is it this good and is data on?

Hello,

I have a problem with my Z3C (more likely with Android Lollipop), the "Phone" (System App) It's draining all the battery by itself (about 20%++, more than the screen) and also preventing the phone from entering in "deep sleep" mode.

I tried making a factory reset and I still have the same issue, I contacted Sony support and they told me to repair the phone with the PC companion utility, but It didn't solve anything.

I'm non-rooted but I installed wakelock detector and did a little trick to watch wakelocks and I found that the process that's draining the battery is called: "gsminboundsmshandler"

I'm running out of ideas, should I root and install a custom ROM? is there any way to disable the sms handler (maybe changing the SMS centre number) ?I don't know what to do.

Thank you.

P.S: It seems that I can't post images until I reach 10 post, so I can't show stats of my battery.

My battery life has been a disaster since 5.1.1, this is the usage of yesterday I would like your opinion on it,

Thanks and have a good day.
