Poor Battery Life - .246, Ext Battery, Better Batt. Stats... info inside

I've searched to understand what's keeping my phone awake and killing my battery and I can't figure it out.
Some background on me:
I'm very familiar with using SS, HoB, flashing ROM's, wiping. FDR, etc, for the Bionic.
Have Better Battery Stats to try to watch what's eating battery.
was on .905, did FDR, used HoB to get to .246 leak after it was confirmed same as the OTA....
Now on .246, rooted with HoB.
Not using TiBu to restore any apps or data.
Have installed better battery stats to understand what's keeping my phone awake.
Whether on the stock rom, stock rom de-bloated, or Eclipse...
Unless I use smart actions to turn off cellular data + background sync (while on a stock rom) there's one common thing keeping my phone awake (kernel wakelock):
bpwake
If I turn off cellular data + background sync then I don't get gtalk notifications/messages, and I've even had some texts not come through when I had those 2 features off (which I thought was strange, not even mms, just regular text messages) and the text never came through even after they turned back on.
I understand that if you don't use your phone a lot, AndroidOS is going to take up a bit of the power drain. No worries there.
But the fact that I'm on an extended battery and I'm halfway through that in less than 5hrs with MINIMAL phone usage- that just doesn't seem right... I could understand that with the standard battery..
My concern is that the "keep awake" time seems rather high in relation to screen time...
I can't find anything on bpwake other than a post about the droid razr, and there wasn't ever a response to that post.
Anyway, I've attached some screenshots of my kernel wakelocks from BBS, as well as battery readouts from the settings and screen on times plus the AndroidOS keep awake time.
I know it doesn't look like the phone is waking up very often, and I've seen much worse in the past, but it seems as though there's still something that's keeping it awake.
I'll try another FDR, and reload .246 through HoB and see if it helps any but I figured I'd reach out here for any help.
Thanks

Your first problem is the 30 mins you went without data. The phone when it does not have a signal will continuously attempt to regain the signal. That is what is triggering the wake ups. If your going to be in dead zones put it in airplane mode.

Interesting, is that true even if you turn mobile data off? It's not clear if the OP turned it off or was just in a dead zone.
I ask because I'm chasing the exact same problem on Stock-Rooted .246, on a stock battery. I don't charge at night, rather I charge in my office during the day. So my phone sits off the charger during the night so I get a good idea of battery drain in standby. Since loading .246 OTA, with data/sync/4g on sitting overnight I was seeing a 12% drop in a 7 hour overnight period, with GSam Battery Monitor showing most of the drain going to Kernel activity. Not bad I guess, but seems way high to me. In comparison my previous phone (Dinc2) would only drop about 4% overnight with data/sync on.
So in an attempt to improve it and get her to sleep, I turned off Mobile Data and Background sync, leaving just the cell radio on. It's my only phone so I'd like to at least be able to receive an emergency phone call in the middle of the night, god forbid. In the same 7 hour period, with mobile data/sync off, I saw an 18% drop, GSam saying 49% of that went to Kernel activity. So, no mobile data/sync, yet the Kernal is still that active, with more drain??? What in the world is the kernel doing, it should be in a deep sleep. Any insight?

Not sure what the no service was about, as I've got service where the phone is parked most of the day (at my desk) but I notice it is still saying I have no data connection or no signal as of now (2h23m off charger, 35min w/ no data connection, 28m w/ no or unknown signal).
Anyway, I've gotten the kernel wakelock (bpwake) down significantly by turning 4g off and leaving it with 3g only.
Battery life is rather exceptional now with only putting the phone in 4g if it's necessary...
Eventually I'll try Eclipse again and see how that works with 4g off and using 3g exclusively (when I'm not on wifi, of course).

Just to eliminate this variable, I should also state I show radio signal was good, 4-5 bars all night long.

You say you're on .246, forgive the Noob question, but how are you switching it to 3g? I appear to no longer have that option in .246 OTA.

I'll have to second the question above - how are you able to turn 4G off Dan? I'm on stock, non rooted .246 (planning on root is what brought me to this part of the forum) and the only trick I know to manipulate the network type is *#*#4636#*#* - last night I switched to LTE only and all of maybe 10% overnight. Of course, I can't make any calls (no calls over lte iirc?)
thanks for looking into this! I'm going to have to monitor battery stats a lot more with this phone...

Digging through more GSam stats, I'm seeing 300+ wakelocks from the mediaserver. I'm sure this is probably not helping matters. Anyone know what causes this and how to stop it? I'm certainly not listening to music or viewing pictures in my sleep.

I'm using the lte switch app for the thunderbolt to turn off 4g. Available from the play store.

I started using BBS as well, my BP Wake is in check, though I'd still like to know what that is.
However, A big draw I'm seeing now is very similar to the OP's screen shots that he didn't mention. Anyone know what OMAP_USBHS_Wakelock is? I googled it, but Only references I see are just a few others just asking what it is with no resolution.

This should help.
First, I found this: http://forum.xda-developers.com/showthread.php?t=1886166
Which mentions wakelocks and battery drain. Same as yours and the OPs.
Next, I decided to search *just* wakelock in Google: https://www.google.com/search?q=wak...zilla:en-US:unofficial&client=firefox-nightly
Which led me to the following two links here at XDA:
http://developer.android.com/reference/android/os/PowerManager.WakeLock.html
An explanation about PowerManager.wakelock methods used in Android, and
http://forum.xda-developers.com/showthread.php?t=1827676
"A Comprehensive (but not by any means definitive) Guide to Wakelocks"
That should answer most questions.
)This next part is me surmising - I may be way off base, but this is what I gleaned from reading through all of these things quickly)
In our case, it seems like the kernel is now built in with some sort of USBHS driver for our OMAP chipset, which means that it now allows programs (apps) to call that PowerManager.wakelock method and keep the phone (or specific parts, such as the chipset, CPU, etc. - which means, of course, more battery drain.

The problem is the weak mobile network signal and the power it takes to maintain it. On the other hand, the weak mobile network signal is apparently a problem in ICS only and GB does not have this problem to the same extent.
In some ROMs the battery drainer shows up as "Android OS" but in others it shows up as "Phone radio" or whatever it is that signifies that.
I do have the GSM/WCDMA hack enabled though and it seems to only happen with that.

So did anyone find a solution? I'm in the same boat. My extended battery is not lasting in ICS like it did in GB. I cannot even go 8 hrs with minimal use off charger.

Zetachi - the only thing that I've been able to do in order to increase battery life is to turn off 4G unless I need it. With using strictly 3G (and wifi when I'm at home) I'm getting much better battery life.

LOL kind of defeats the purpose of having a 4G phone and service

Eh, you still have the 4G without the drain. While not the most optimal situation, at least its easily remedied with just a few clicks.
Certainly an inconvenience, but those of us with the Droid Bionic have got to be used to that feeling by now!

I use WiFi at home and 4G everywhere else. I get great battery life.
Something I learned, though, is that the Gmail app will sync with the servers every 5 minutes if you create and save (not send) a draft. That will eat up a lot of battery over the course of a night (or day).
Something to think about.

Get a full charge and run this in safestrap.
I let mine reboot and charge again cause safestrap Burns battery. Then run it till its dead.

Be careful with this method. I know you posted this a while back but it may be helpful for others to know that the phone can lose data all-together using this method. It has happened to myself and other users as well.

[Q] Weird "battery drain" when lightly using the phone

Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance

I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.

Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).

I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.

Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.

@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?

Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?

Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/

I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.

I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.

Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.

What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.

The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.

Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.

I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.

Let's discuss this battery problem

This is not another, I love this phone BUT the battery is too small.
Currently there is a massive bug affecting the T-Mobile (possibly others) Galaxy S6 (unconfirmed on edge)
Symptoms
Massive Battery Drain while Idle
Cellular Standby top Usage in Battery Stats
Random WiFi issues
Self Diagnosis
Go into Battery
Tap Cellular Standby and remember the "Total Connection Time"
Go back to "Battery" and hit refresh
Check Connection Time again
If the time increases but you are NOT using any applications, on the phone or downloading you are affected by this bug.
Fixes
Turn WiFi calling OFF
Disable VoLTE (VoLTE toggle is in the Phone App/More/VoLTE.)
Update - Turning off WiFi Calling along with disabling VOLTE appears to have patched this issue for now. You can still use WiFi like normal and turn that off and on and it shouldn't have any issues.
So lets discuss this, I have not been able to fix it. WiFi on or off, WiFi calling enabled or disabled nothing seems to correct the problem. Its as if the phone is ALWAYS on a call.
Edit- VoLTE seems to have corrected the issue somewhat. What I did is turned off VoLTE, Turned off WiFi calling and then turned WiFi off and back on. My Connection Time hasnt moved since. How long this patch lasts for, I don't know.
Mods - Please monitor this thread if you could for battery naysayers and complainers. We are out to diagnose and fix the problem, not complain about it.

Thanks for starting this thread. I have tried pretty much everything, including uninstalling/disabling most apps, turning off "keep awake" for what's left, etc. I just tried turning of VoLTE and I still lost about 2% in 15 minutes with my phone just sitting on the desk (no use). My next course of action is to try a wipe. I really don't want to take this phone back. I still think this is some sort of bug with 5.01. My Nexus 6 had battery life issues until 5.1 and now it's awesome.

Okay the VoLTE trick fixed my high cell standby drain.

I've used quite a few lollipop builds and I've noticed on just about all of them (including the s6) Google play services runs pretty high. Haven't had the phone long enough to accurately test, but I'd suggest for those seeing it run pretty high to completely disable auto update of apps. That should help limit its ability to wake up the phone.

I actually disabled wake for that app using App Ops. Nothing in Gsam or regular battery stars is telling me anything.
I just performed a wipe. If that doesn't do it, I give up.

Ok guys let me throw in my 2 cents.

that was yesterday usage. I had wifi on the whole time yesterday.
Now today usage wifi off since 100%, i have no ****ing idea why facebook is using that much, ive use it 10 mins at most.

Facebook is like a hydra when it comes to app permissions. It has the most permissions to your phone with few apps to rival it. Use an app that blocks particular functions you dont use in the facebook app (GPS, contacts, etc) and just install this (must be rooted) https://play.google.com/store/apps/details?id=com.findsdk.apppermission&hl=en

I realize it hasn't been a full days of use yet, but the Cell standby sums up the battery issue drain. I'd prefer to keep VoLTE on, and we should be able to without this being a problem. It was on, on my G3 and I didn't have such significant Cell standby battery drain. Any idea of another cause?

So, I finally caved in and wiped, even though I have had the device since Monday and battery has been bad all along. Prior to wiping, I was losing around 2%/15 minutes (8-10%/hr) without even using it. After wiping, seem to be losing around 4%/hr. I am not using it at all, just testing the idle drain. It's definitely better.
My question to the fine folks here: Does 4%/hr with no use seem reasonable? I only installed minimal apps and none of them are doing any kind of autosync or update. I have one exchange account set up through Nine and then my gmail account.

My question to the fine folks here: Does 4%/hr with no use seem reasonable? I only installed minimal apps and none of them are doing any kind of autosync or update. I have one exchange account set up through Nine and then my gmail account.

4%/hr completely idle still seems high

For me, even without ever turning on my phone, it's syncing with breaking news apps, facebook, twitter, hangouts, gmail push, work email push, a couple online RPG games pushing me alerts and so on. My battery drain ironically isn't stemming from apps syncing and emails/alerts being pushed constantly throughout the day. It's the cell standby for me.

contributing factor?

Seems to be the cell standby for me too. Disabling WiFi calling and VoLTE has fixed it for now.
Is there a Samsung support channel where we could get this recognized? It seems really asinine that people are exchanging the handset for what is clearly a software defect.

VoLTE seems to be my problem for now. Disabled it. And fully charged it to 100% and its now at 75% and cell standby isn't even on the battery stats list.

So, I can't believe I'm saying this, but a factory reset totally resolved my battery issue. It was only 4 days old. I couldn't see how it could have possibly been fixed by that, but it was a last resort before returning it.
Now I have some pretty normal Battery life. I love this phone!

If you hadn't been a douche in your follow-up reply, I certainty would consider it.

Having this issue as well..after having a nice battery cycle of almost 5 hours sot I'm seeing the same thing in bbs, losing 6% an hour idle. Will try the fixes to see if it helps thanks guys

so im getting the edge on the 15th
should i factory reset it right when i get it ?

The only thing I did out off the box was take the OTA and root. Maybe the OTA set it off? I pretty much have the same apps installed now.

Doze not saving any battery

Hello,
I got the 6.0 OTA last week. It seems to have some minor issues with wifi, but it doesn't really bother me too much.
What I am bothered by is the fact that Doze doesn't really save any battery for me.
I've left the phone on my desk during the night a few times now and every morning the battery seems to have drained about 15% like it did in lollipop.
Just last night I left the phone face down, so the screen would never turn on, and it had 50% at 1:00am and when I woke up at 9:00am it had 37%
My brother has a Nexus 5 and says his phone only looses like 2% during the night.
The only two items on the Battery Optimization list that aren't optimized, are Google Play Services and Motorola Notification.
Is Doze not supposed to work on the Moto X?
What has been your experience with Doze like?

I am experiencing the same.
During the night it looses from 10 to 15%. I flushed the cache partition and uninstalled Greenify(no root) , but it didn´t get better results.

Me too. Besides it´s more fluid I was excited about Doze more than anything else.
Some say that you should do a factory reset to get Doze working.
Did you try this?

Not yet, as I like to leave factory resets as the last option.
Hopefully there are other things to try first.

Has it got something to do with Moto Display? DND doesn't automatically deactivate the sensors like Moto Assist used to keep the screen dark and the phone still flashes notifications at night. Does that consumer battery?
You can choose the screen to go dark from 11pm-6am in Moto Display, but they removed the option to define custom timings. The flashing interval for Moto Display also seems to have been reduced which becomes a little annoying.

It kind of works for me. Expect to lose 8-10% whole night because Motorola radios take up more juice than any other manufacturer. Without Doze, this drain was upto 14% per night.

By radios, you mean 3G/4G and wifi? If so, isn't Doze supposed to turn those off for long periods of time anyway?
I'm going to try and turn off Moto Display for a while and see if that makes a big difference.
EDIT: Turning Moto Display off didn't help at all. Last night the battery dropped 15%. Also, I have 2 alarms, set 15 minutes apart, that only went off when I unlocked the phone 30 minutes after the last one was supposed to go off. I use Circle Alarm, so I'll be switching to the stock alarm app to avoid this.

Doze never turns off radios, rather turns off apps' ability to wake up device (or communicate with radios and push information to the user). The cellular radios take up more battery in Moto X than other phone. So, expect 8-10% drop per night (in a nexus 5, drop per night is 5-7%). Anything higher than that, maybe some apps are rogue. Try to find out what apps are waking up your device. BTW, Moto Display doesn't take up much battery because it runs off the DSP, not the main cores, and second, the phone has AMOLED panel, which lights up only the needed pixels.

Here it happens like this: I go to recovery and Wipe Cache, then leave the phone idle: doze works, losing roughly 3% in 8 hrs. The second time I let my phone idle, doze doesn't work anymore (I guess?), losing about 10% in 8hrs. I did a clean install btw, wiped /system, /data, /cache and even done a factory reset later. Battery is still not that bad, I just think that I could do better at standby, especially when on 4G/LTE... I'm currently getting around 4h30 on WiFi and 3h30 on 4G, in a 15 - 17hrs period, with good coverage, 30-50% brightness and sync on.
The thing that is annoying me the most on this 6.0 is the heads-up notification... This "Operator Info" keeps popping up when I receive a notification, and when I'm on ladscape while on immersive mode, the area where the status bar is supposed to be get's like this:

So it seems possible to get the 3% drop overnight....
Also, I'm not having the "Operator Info" problem. Mine doesn't show the operator at all, and I can no longer find the option to turn it on/off

I tried this:
- wipe app cache
- wipe system cache
- turn off wifi scan
- clear radio settings
Now if I let the phone without interaction for some time it doesn´t drain the battery and it consumes only 5 to 7% over night (about 7 to 8 hours).

Turning off wifi scan seems like it could do the trick. I'm trying this tonight.
Also, what do you mean by "clear radio settings" and how do you do that?

Weird battery problem with Marshmallow. UPDATE: LTE problem!!!

Hi everyone, hi experts!
I´ve a problem with my Z3 compact. I was having a huge battery consumption from the Google Services so I decided to save everything, repair software using the PC-Xperia Companion and start from scratch. But after that now everything is even worse! My battery drains about 40-50% in one night whithout using it! This time there is no meaningful info from the apps... power consumption in mAh in every app looks small... but the overall battery drains very fast so I can not detect where the drain is coming from. Here some pictures:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
What can I do now? Reinstall again? Send the phone for repair?
Many thanks in advance!
UPDATE: After forcing the phone to use 2G or 3G the battery drain stopped. So it seems that it happens only when LTE is selected (independently wifi is enabled or not). Question now is if this is a problem of the LTE module of my phone or a problem of the net supplier.

Chances are Google has a lot to do with it. Do you have poor reception in your house? If the phone is straining to pick up and reply to a poor signal, that can have a big effect on overnight battery. Try switching to 2G overnight.
Other common cuplrits are Facebook and Whatsapp or messaging apps that are constantly pinging data. Try turning the wifi off as you sleep. Also using location based wifi will make a difference as I see your wifi stays on constantly. Have you disabled wifi and bluetooth scanning in location settings? Disable Google location history. I know this sounds daft but go to settings/storage - hold down cached data and delete. This won't effect any apps or services but does make a diffference, I didn't believe it myself until I tried.
Looking at your graph there is something keeping your phone awake at night. Try installing BetterBatteryStats, this will give you more of an idea which service is causing the kernel wakelocks, post your questions about the name of a service causing the problem on the thread as they are very helpful with the answers.
There are lots of reasons why Google Play Services are eating your battery, try a few fixes yourself, check which version of Play Services you have installed , anything older than 9.4.52 needs replacing. Remove your google account, wipe data for Play Services and Download manager, restart to recovery, wipe cache/dalvik. Restart phone, add account again.
There seems to be issues with fitness trackers and bluetooth, if you have bluetooth on all the time, see what happens if you turn it off?
I can recomend Greenify app that can make a difference in putting apps to sleep, it also helps you see which apps are awake and on.
Check in settings/developer options/running services to see what's on and using most memory, you might be surprised at what you find. To enable developer options go to settings/about phone - press on build 8 times, then you get a message that develper options are availabe in the settings menu.
If all else fails, I can recomend Slim 2.5, which is giving me 4 days from one charge and moving to a custom rom isn't as difficult as you might think.

I noticed that after installing new ROMs battery usage is relatively high in the first day or so. Hence it may improve over time (to some extent at least...).

Hi!! Thanks for the help!! I´ll try some of the ideas you suggested. Here some answers anyway:

WIFI is always on because I´m at home. I always had wifi always on without problems. I´ll disable location though... just to be sure this is not the problem.

Question now is if this is a problem of the LTE module of my phone or a problem of the net supplier. I pay for LTE so I want to use it... but not at the cost of the battery. Is this normal with LTE or do I have a problem?

The cell location for your 4G connection might be further away or on the edge of connectivity compared to the location of the 2G tower. Everyone assumes that the 2G/3G/4G transmitters are all in the same place, but it's very rarely the case. Most 'old' masts with 2G & 3G don't have room for the 4G transmitter as well and the service provider often needs to install 4G somewhere else..
So if your LTE connection is a long way away, your phone will have to be straining at full power just to keep the connection alaive.
