[Q] Bizarre Battery Drain

Dear XDA Members,
I'm having some issues with the battery of my Samsung Galaxy S4 Mini. About 2 weeks ago, 2 phones in this house, a Samsung Galaxy S4 Mini and Huawei Ascend P7, started (quite simultaneously) to have battery issues. They both are on the stock rom and are not rooted. To sketch the degree of the issue: the Huawei had about 40% after 7 hours standby with 3 minutes screen on time. The Samsung lost 65% in one night just being idle.
At first we thought it were the phones that were having the issues, so we returned the Huawei to the shop (about 40 kilometers away). The people of the shop called yesterday, saying that the phone is lying in the shop for over 3 days now, still having 40% percent of battery. This made us think it was something with the antennas here in the neighbourhood.
In the mean time we had already bought a new battery for the Samsung (an original Samsung battery), and I have performed a factory reset. The battery still drains quite heavily when airplane mode isn't enabled. However, last night the Samsung still lost over 15% with airplane mode enable and all recent apps killed.
I completely lost track about what the issue can be. To me it seems that the fact that the phones started having issues at the same time is caused by an external factor. But in that case, I cannot explain the 15% overnight battery drain on the S4 Mini on airplane mode with a new battery. Should I return the Galaxy S4 Mini to Samsung to have it looked at and fixed, or should I try some other things first?
If anyone wants some more information about the issue or the devices, I'll happily provide it.
Thanks in advance!
Note: It is not my intention to root the S4 Mini or push settings to the limit to have 0% battery drain, I just want 1 or 2 days of battery life again, depending on the usage.
Edit: There are also a OnePlus One and Galaxy Gio being used in our house, who do not seem to have severe issues. This confuses me even more about the external factors (antenna failure?) that might be draining the battery. We all have the same provider...

There are many ways to save your battery life:_
some of them are as follows:---
***Go to recovery and clear cache this will help improve the battery.. Use clean master from play store, which will disable / stop unwanted apps, clear app cache.
***Try using Greenify
***I recommend GSAM battery monitor app from play store. It's very easy to understand and is very good at locating battery issues.

In settings>battery check your mobile network signal of last night and see if there is any app that is sucking your battery.
You should try greenify but you need root access.

Thanks for your answers. If the problems do not get solved I will indeed try some of those apps (I've used Greenify earlier, I know it's great )
I've monitored the apps draining the battery, and in fact there aren't many apps that use a lot of battery. It's mostly the screen or mobile radio active, which makes me think it's something antenna related.
I've spoken to my neighbour who is a customer of the same provider, and he indicated he has issues to since a few weeks. I mailed to my provider and see how things turn out
Thanks for your tips!

Yeah i also think the problem is in network quality, you should try another sim for some time and see the difference.

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.

Utter rubbish, and this device is still to new development takes time and someone who knows how to build working recovery ect. 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.
Sent from my F3111 using XDA-Developers mobile app

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

Z3 Speakers, Battery Life & Updates

Does anyone here can tell me please if the Z3 speakers are actually much clearer/better/louder than the newer Z3+ or Z5? (Most YouTube videos says so).
And is it true the Marshmallow (the very last/latest one) update deleted the Battery saving mode and instead replaced it with an "inferior" Doze mode which then in turn severely affected the overall battery life?

Owners: How's the battery?

XZ Premium owners, how are you finding the battery? My Z2 and now Z5 have never guaranteed me a full day, and now that my Z5 is a bit older I'm charging twice daily. So I'm torn between the Z5P and the OP5, for all it's flaws -- is battery life better than the Z5? I'm particularly interested in dual-SIM, but I assume the battery life won't be all that different to the single-SIM handset.

My last Sony phone as a daily driver was my Z3. Battery was fine on that until I did anything that made the CPU go into meltdown.
On the XZ Premium, Sony and Qualcomm have got things nicely under control - which means the phone doesn't run too hot (which in itself plays havoc with the battery, and can make it near impossible to charge) - and the battery doesn't seem to take much of a hit even when playing video or taking photos.
My phone can still get hot when taking photos and give me the warning, but despite me using the phone heavily, the battery (given its size) works commendably. Especially if you enable any of the stamina modes
I could live with most of these modes enabled all the time, with the only issue being when using an on-screen keyboard (it missing characters pressed), and then the battery lasts even longer.
tl;dr - the battery is good and I'm very impressed. You should get a whole day of usage without fear, and with a good deal of screen-on-time.

I got this phone yesterday. My previous phone was the Z3 Compact which was the king of the battery life back then, but now i think the XZ Premium is better than the Z3c while i use certain apps and it consumes more battery only when i use the Camera, Photos app, Video app and Youtube. I haven't used Stamina Mode yet.

Mine battery life is good, my best was 31 hour running always under 4g with 4+ hours of screen on
I do a day and a half with every single charge at the moment

Thanks everyone.
@Katsigaros, could you let me know how you're getting on after a week or so? I don't plan to buy until the start of this month, so I'd be interested in progress.
@Tonyevol that's impressive for standby, but is 4 hours SOT good? I had the same response from a few people on Reddit, with 5 hours of SOT, but I though 6+ was kind of the norm these day, with good phones getting 7 or 8.

I am getting 5-6 hours SOT as of now. Over a month, I have seen marked improvement week on week. Once we get root/ twrp, we can disable some processes and programs that aren't required thereby maximizing the battery juice.

Little better than Galaxy S7 Edge which is my previous before. I am quite happy with battery.

After the first time I used it i performed a full recharge from 1 to 100 % to calibrate the battery. I am watching a lot of videos and because of that the battery lasts me 1,5 - 2 days. If I am not watching videos I can get almost 3 days.
I will have a clearer view on battery life after one month but right now I am very satisfied with it.

It depends a lot about the way you would use it. For example I'm all days around without wifi connection avaible and of course 4g connection all the time working drains a lot of battery juice. Also having Facebook running all the time with instant messaging always on makes differences. Without using Facebook and limiting display luminosity would grant a much SOT

Bluetooth draining battery

My battery is draining fast - when I check the battery consumption, Bluetooth is at 97%
I have a Sony Smartband 2 and it's always connected, however this issue has only started recently
My Z5 is a E6603
Android 7.1.1
Build 32.4.A.0.160

I just made the account to say that it's also happening on my Z5 Premium. Always connected to my Mi Band 2. To make it better, it only started some 2 weeks ago, first month on 7.1.1 was pretty decent.
Now, I've never reached 97% Bluetooth, but 90% is normal. It reports using over 13000 mAh (out of a 3.430 mAh battery, just wow). And even though the Settings is obviously wrong, over those two weeks my average battery usage (w/ screen on) did raise by 10%/h (to ~35%/h).
Anyone managed to fix it without turning Bluetooth off? If not, back to Marshmallow, I guess...

Well, I've tried many "solutions" with no success. Have you tested your device in safe mode? In my case, battery usage shows only bluetooth even in safe mode (some crazy amounth of mAh). That would normaly mean that samo of core apps have somehow gone wrong, but flashing a few firmware versions didn't help... I realy don't have any ideas what to do.
Have someone found any solution that would like to share with us?

I've found it! Google Play Services screwed things for me, so I downgraded it and everything is back to normal. Last version that works for me is 11.5.22. Here is the link: https://www.apkmirror.com/apk/google-inc/google-play-services/google-play-services-11-5-22-release/
