Does wifi kill battery faster?

Does using wifi drain the battery? Is it better than using the actual 3G or 4G?
Sent from my HTC Vision using XDA App

I'm sure someone has a way more technical answer but I would think not. I have no issues with drainage on wifi, as on 2g its on the network constantly and not continually searching for towers.

If you are connected to a wifi network, it saved much more battery than using 3 or 4g. However, if you leave wifi on but don't connect to a network, it will drain battery

ok cool thanks alot man. Idk when I'm home I just like using wifi better, correct me if I'm wrong but it seems faster. Thanks again

Turning on anything more than necessary will kill your battery faster. Not always by a lot but everything does and wifi wouldn't always be faster because it depends on the wifi's local area connection. Best way to save battery is to go in settings/applications/manage applications the force close anything you don't need running. Make sure you know what it is you're closing or you could run into some problems. If you end up killing a system app and it won't reopen itself, its nothing a reboot won't fix.

DO NOT DO THIS.
Android has its own automatic task management system, and its best if you just let it do what it does best: manage on its own.

Well gee I do it all the time and it works fine. If it wasn't intended to be used I don't think it would come without root permissions and anyone who isn't an idiot will realize that force closing android system will cause problems. But if you wanna suggest a task manager that doesn't actually kill apps and adds some bloat ware, be my guest.

He's not going to recommend another task manager/killer, because Android already does it by itself. Plus, killing a task that is not finished just causes it to respawn. Task killers are unnecessary, and may actually hurt performance and battery life.

I agree that it's best to let Android clean it's own house normally, however I'm getting a little bit jarred off with certain apps starting themselves up at boot-time.
Paypal app for some reason has installed a service on my phone, despite the fact I've never even logged into it and I can't see why it would need a service running all the time.
Also since the latest Google Maps upgrade there seems to be something under my running tasks called Rate Places. I've not used the check-in service on GMaps at all, nor will I ever.
As well as this, since I've been running a modded CM ROM (SparksMod Extra Hot Sauce) then I constantly have Wi-Fi Calling running - again this is useless to me cos I'm not on TMob US.
Any suggestions for a decent app which can stop all these things running before they ever start, and keep them stopped?

Try "Autorun Manager"
I use it, but SOME apps will auto-restart. I think you need the Pay version of Autorun Manager to prevent those from re-launching.
I use the free version, and it gets rid of some of the problem.

WiFi is definitely causing massive battery drain on my G2 with CM6.1.1. I leave it on at night, and if I have 50% when I go to sleep, I'm down to 3% in the morning. Without doing anything.
I'm not quite sure why this is happening, but it is, and it sucks. I can't go back on 3G/4G right now because I'm at just about 4.8GB, and I don't want to go over my 5GB soft cap.
I wish I knew why WiFi was causing such battery drain...

Do you have anything updating automatically (Email, facebook, etc)? That would be my best guess. I leave wifi on when I'm at home and it isn't that bad at all. Also, I'm sure theres an app out there to let you see what is using the wifi for updates and such. I just don't know of one off the top of my head. I have an app like that for 3G data but it doesn't do wifi.

I just went through every one of my apps to make sure that nothing is set to sync, except Google Voice and Email. My battery is at 50% right now, so we'll see what it's at tomorrow morning.
As you can see from the screenshot, WiFi is using quite a bit of battery. I'm not sure why, but hopefully soon (after some testing) I'll have my answer.

Yup, 2 nights in a row, my battery has gone from 40% to dead, simply from sitting on my night stand. I wonder if this is why T-Mobile discontinued the G2... because they knew it would have battery issues, and they didn't want to deal with serving warranties? Hmmm...

Its a bit of a leap of logic to link your personal battery issue with T-Mob discontinuing the phone. T-Mob has a good number of Android phones coming out in the near future, with T-Mob really ramping up their support of Android devices. So its been very reasonably speculated that they are discontinuing the G2 in order to make room in their lineup (and stockrooms, etc.) for the new phones.
I get a full day of moderate usage on my Vision, and can get close to 2 days with low usage. That's very typical for a modern smartphone. I usually get in the range of 2-3% battery drain per hour when the phone is idle. And that's with WiFi always on (even when not connected to a WiFi network) and auto sync of Gmail and HTC stock and weather apps. You haven't mentioned how long "overnight" is exactly, but I'll assume 8 hours or so. So your phone draining from 40% to dead overnight seems unusual. WiFi typically uses less battery then the cell data network, when WiFi is available. I suspect there is something else going on, besides just being on WiFi. If the cell reception is dodgey in your area (or fringe 3G reception), this might run the battery down (even if you are on WiFi) as the phone is constantly searching for signal. Or your radio may be mismatched to your custom ROM. Or you may just have a bad battery. Also, was the battery drain any different when you were on the stock or other custom ROMs? I personally haven't witnessed the battery drain to be significantly different across the ROMs I've tried. But that seems to vary, as there often seem to be people complaining about this or that ROM causing more battery drain.

The reason I thought it might be a hardware defect issue is that my wife and I got G2's at the same time. I rooted mine and have been running CM6.1.1 for a few months now, and my wife has kept hers stock. However, the battery issue hit both our phones at almost the exact same time.
It sounds ridiculous, but conspiracy theories are fun to play with. The fact that I've been rooted so long, and it JUST happened weirds me out. Add my wife's phone to the equation, and it's even weirder. I kept my phone on WiFi and 2G networks only last night (yeah, about 8 hours), and the exact same thing happened.
Maybe I should just get a new battery, I don't know. But I do religiously delete apps I don't use and make sure the ones I do use are syncing as minimally as possible.

[UPDATED: SOLVED?] Google Services causing weird battery drain

Interested in solving a real puzzler? Then read on!
The patient: a rooted, otherwise stock Jelly Bean (JRO03C 4.1.1) Galaxy Nexus. Being used as an everyday phone (and a bit of development).
The symptoms: Excessive battery drain by "Google Services", but ONLY on my home Wifi network!
This is where things get weird: on 3G, on my company's work Wifi, and without network, the battery drain is absent. I can *reliably* cause Google Services to start hammering the wakelocks, and stop them, just by moving to a different Wifi hotspot. There's NO change in functionality: Google Talk, Play Store, and network access work exactly the same. Push messages seem to come in normally too, but I haven't tested that very well. There's no configuration change whatsoever.
More details: After installing BetterBatteryStats, I've gotten a better look at the wakelock draining the battery. After gathering stats for 25-30 minutes, the following wakelock is the top user:
Code:
GTALK_ASYNC_CONN_com.google.android.gsf.gtalkservice.AndroidEndpoint (Google Services): 7 m 47 s (467 s) Count:786 30.3%
So, I decided to check logcat for "GTalkService" messages, and see if there's a major difference between work (good) and home (bad).
Turns out I get a lot of the following at home, but not at work:
Code:
[ 08-15 17:36:02.719 709: 709 I/GTalkService/c ]
[[email protected]] connect: acct=1000000, state=CONNECTING
[ 08-15 17:36:34.461 709: 1177 E/GTalkService ]
connectionClosed: no XMPPConnection - That's strange!
This is repeated a LOT and looks like it correlates quite well with the wakelock.
I use the phone, and I would hate to wipe it completely: I would really like to get to the bottom of this.
First of all, I'm not 100% sure this is a Galaxy Nexus only problem. It might be Jelly Bean, or ICS, or whatever. Would you suggest I post on the Google Android bug list, where the crickets chirp, and major bugs disappear into a big Python black hole?
Thanks guys! If only for reading this far!
Update 2012-10-02:
OK, I have eliminated my firewall from the equation: obviously I can't necessarily just whack the work's firewall without consequences. Nothing's blocked, and all services on the phone seem to work.
As for other devices: I dug up my old Nexus One (Gingerbread, stock), and upgraded my Transformer Prime to Jelly Bean. Both do not show the error in logcat, and neither have the battery drain issue. Just for kicks, I checked the version of the Google Services Framework on all three:
Samsung Galaxy Nexus: 4.1.1-398337
ASUS Transformer Prime: 4.1.1-438695
HTC Nexus One: 2.3.6
Wanna bet there's a bug in 4.1.1-398337 that got fixed in 4.1.1-438695?
Further update:
I also tried the following with no success:
Delete app data for Google Services Framework (NOT RECOMMENDED!)
Remove Google accounts from the phone.
Re-add Google accounts to the phone.
Update: 2012-10-04
I think I found a workaround. It looks like it's a domino effect thingy that happens here:
1) I've got a Netgear N600 ADSL/Wifi router at home. On my 2.4GHz radio, I set up two access points: one for my stuff and one for guests. I made sure to delete the guest account from all my Wifi equipment to make sure there's no "fighting" or "flapping".
2) It appears that the phone ignores the Wifi-'stay connected while sleeping' setting, or the radio is broken. When the phone goes to sleep, it disconnects from Wifi.
3) When the phone disconnects from wifi, the Google Services Framework lose connection: this causes the phone to wake up.
4) When the phone wakes up, Wifi gets re-established. This makes Google re-connect.
5) The phone goes back to sleep and we return to step #2.
This causes a LOT of wakeups, lost connections and other crap. Since the phone doesn't lose connection when it's awake, it's fricken difficult to debug. Also, it's NOT a signal quality issue. My phone can be right next to the access point and it wouldn't help.
So, could you guys try different access point settings at home? I've heard WMM, QoS and some of the protocols could cause the Galaxy Nexus's radio in Jelly Bean to go a bit wonky.

Could it be that your home router's firewill is somehow blocking parts of GTalk traffic, causing it to continuously retry connecting?

Nope, I checked that: there's no firewall. At work there is, but it doesn't affect my phone (services are not affected visibly). Google Talk works fine in both situations.

any developments in this? have an s3 which is behaving similarly. my WiFi is always on as I'm usually near a hotspot at work home /gfs.gtalk_async wake lock showing up in better bat stats. been having battery drain issues for a while now and decided it was time to do some research.turned off pretty much every synch/auto backup app on the phone but still draining, not quite as bad, but still seems to struggle to stay asleep for very long!

Does anyone have solved this.. i have got exactly the same situation as Jan. No trouble at work but only at home.

Not affecting ASUS Transformer Prime
Nothing new here, except I also cross-checked with my ASUS Transformer Prime. There's no drain on it, and also no errors in logcat about GTalkService.
I'll post an update once I've checked my trusty old Nexus One out of storage, that'll happen next week, though.

Interesting note about the wifi. I only seem to get this problem during the week at work, on the weekends it doesn't happen that often. I get poor data connection at work and rely on the wifi instead. I'll try to not use the wifi for a day or so and see if the wakelock is reduced. Thanks for the tip, this has been a problem for a while now.

Just take note: in general Wifi uses a LOT less battery than 3G. A better test might be to disable Wifi AND sync.
Jan

some decent insightful ideas here. My S3 on official stock based custom has bad drain over wifi. My google services framework version is the 4.1.1-438695 which isn't affected in your case so it's not that.
Better battery stats at first put google maps as the wakelock so I realised it's location service was left on so I turned that off. Then BBS varies and shows different apps and what not causing wakelocks but the drain remains the same.
My router is an Asus with custom linux firmware Tomato with a robust plethora of functions. I updated it yesterday and put the settings back closer to default. I'll have to try disabling WMM and QoS settings as their both already on at the moment. Also the kernel developer i'm on to quote: "Made a change in wifi offload filtering to deny muticast packets but allow multicast DNS packets."
After leaving wifi on last night the drain still remains at about 10% per 3 hours. Compared to before it used to be almost 15% per 3 hours. BBS doesn't show wlan_rx_wake as the top wakelock as most common before as that's down to running for 8 minutes in 9 hours rather than the top around 45 minutes. Instead battery-monitor is the top at a little over half an hour in the 9 hours. Googling battery-monitor shows little useful information but I assume it's like before where Wifi is waking the device and something OS related that turns on with it gets given the wakelock status although its not the trigger.
I'll have to try disabling WMM, QoS, auto-sync and gtalk and see how I go. Hopefully you're right about it being wifi disconnect related and can be fixed.

Have you tried disabling the WiFi Power Save Mode on the S3? From this article:
http://www.s3forums.com/forum/galaxy-s3-general-discussion/1329-wifi-tip.html
1. Open up the Galaxy S3 phone dialer
2. Dial *#0011#
3. Look for the “ServiceMode” screen and press the left menu button
4. Select “WiFi”
5. You should see that the “WiFi Power Save Mode” button is “ON” – turn it “OFF”'
My colleagues with the same phone has serious battery drain until they use that.

I seem to recall that the Google framework sends/receives a keep-alive packet once every hour or so. LOTS of stuff in the Android framework keep TCP connections open from the server side because otherwise the service provider just kills them. Blame stateful firewalls.
What could be happening here is that the WiFi chip offloads a number of these functions from the main CPU: i.e. it's got a simple TCP offload stack that just queues data for the main CPU to wake up. If the WiFi chip receives a keep-alive TCP packet with no payload, it doesn't bother to wake up the CPU and just absorbs it. If the WiFi chip goes to sleep, rather, it never receives these, the connection dies and the CPU needs to wake up on timeout and re-establish everything (eating battery in the process). It's paradoxically cheaper to keep the WiFi chip running on full power, than to let it go to sleep. This is pure speculation, and only one of many scenarios that might fit the facts.
The S3 has the *option* to change the WiFi sleep-mode from aggressive (default) to a value that lets the entire system use less battery. The Galaxy Nexus doesn't: which means that it may, or may not have the sleep-mode built in. In any case, it seems my router can remotely trigger disconnects when the main CPU is off, and by switching settings on it, I managed to perform a workaround. Unfortunately the Galaxy Nexus (on Jelly Bean, at least) seems to have a serious bug in this respect, and other people are not so lucky: http://code.google.com/p/android/issues/detail?id=35352
It seems that the core issue (WiFi disconnect), causes a knock-on effect, raising Google Services Framework, Android OS and potentially anything that syncs's battery profile.
Jan

Getting good drain now 1% an hour compared to 3%. Seems setting WMM to auto rather than enabled in tomato fixed it. The night before I had it disabled as well as QoS and it was bad as well. I will test further to be certain what's the scenario.
I've got a second S3 that's been suffering as well. Having two to test makes testing much faster. The service menu power save mode off didn't help. It caused strange disconnects with WMM in all states. S3 wifi menu would state poor connection and wouldn't reconnect. Note the S3 already has strange disconnects to begin with I find but in this case it sometimes wouldn't reconnect. Also restarting the phone resets the power save mode to enabled.
Can't find any information on a difference between enabled and auto in tomato WMM. I'll be sure to keep testing.

New Google Services Framework
Hey guys,
looks like Google Services Framework got a version bump on the latest Galaxy Nexus update: it's now listed as version 4.1.2-485486
This is for JZO54K (4.1.2).
It could be that they've fixed the knock-on effect (but the core issue is likely the same, since the radio code is apparently exactly the same).
Jan

I have this same wakelock on my evo 4g lte. Same log error exactly. Only on my works wifi. Problem is eliminated when running a Vpn on the phone. Only caveat Is all the free vpn services seem to disconnect after a period of inactivity.

I know this is an old topic but I had the same drain (30% overnight) on my Galaxy S2.
After weeks of searching and trying different things I found the solution.
Change DTIM value in your router configuration from 1 (default) to 255.
This value is usually in Advanced->Wireless tab on most routers.
Now my phone uses 2% battery overnight with wifi on, sync on instead of 30%.

Thanks, will give it a shot. Also, because of your post, I discovered that toggling wifi on and off stops Google Services from draining. It will still drain, if your wifi is set to turn off, when the device sleeps. I really think you hit the nail on the head, discovering the source of the problem. It's an issue I have been trying to fix for a long time and your post at least got me to toggling the drain. So thanks again!

Would love to he root cause of this... I had the same problem on my s3 and now on the s4.with and without custom roms etc. The problem only is work, and I'm putting it down to some service that the work firewall or something blocks... Only solution I've come up with is turning off the wifi when I'm at work.. Else I get in excess of 15min /hour of wakelock.
All apps etc. Up to date, sync on/off, no difference, all "location" settings turned off.
I give up.

Wifi signal strength!
Whatever Google did to cause a variety of wakelock problems, having a strong wifi signal seems to solve them. Apparently, wakelocks occur when there are unreliable connections to Google's servers.

[Q] Mobile DATA keeps turning on Automatically

Every since Verizon pushed the Lollipop update to my N4, my "Mobile Data" turns back on all by itself after it has been disabled. It even turns back on when I am connected to wifi.
Has anyone else experienced this and if so can you please explain how I may fix this.
Thanks in advance.

Not exactly that but I have noticed that now I'm always on 3g when I'm usually on 4G all day long same area this is crazy

Mine is also randomly turning on Mobile Data too after the Lollipop update. I have a small data allotment with VZW, this could send me into overages.
I seen on one thread, searching through your downloaded apps to find out which ones have "change network connectivity" in the permissions. I happen to have 6 of them. Some you can disable, but it removes the updates, other you cant disable without removing it.
Another recommendation was hitting settings from the pull down menu, wifi, advanced, then uncheck the "smart network switch". Mine wasn't checked to begin with, so I'm out of ideas til I start removing apps one by one...

The data has been turning on by itself during sleep time on my Note 4. It caused the phone to use 500mb of data in one nite. My data is always off, wifi is only on when using the phone otherwise it's off too. I called Verizon and they have no clue. This is my 2nd new Note 4 for myself & my wife, nothing but problems. Think we are going to switch to anything other than a Samsung phone.

Well, I've systematically removed all 6 apps one at a time. The Youtube and Facebook apps, I was only able to disable them instead of removing them completely. In the end, the phone still turns on Mobile Data by itself. This must be something internal with Lollipop. I have a small data allowance and I'm afraid its going to go over simply because it wont stay OFF even with WiFi available!!

I would call customer service and have them ship you out a replacement. This is our 3rd phone and hopefully it will work as it should. Good luck

Outcast,
I've had my Note4 since it was released in November. It didn't have this problem with 4.4 Kitkat. It's something new with Lollipop and I doubt a new phone would solve this problem, could be wrong.
How involved is it to go back to Kitkat?

I'm not chancing voiding my warranty. They replaced my phones by them and not by request. Our phones get hot and get a warning then shuts down, apps close constantly and the phones consistently reboot on their own. Then the data turning on by itself. The other problems I don't think are software based but hardware failures. The data can very well be software related.

I have the same problem and i used up so much of my data when i am at home where the wifi connects automatically on everything else. On kit kat this never happened and i am attempting a downgrade so you might want to try that.

I was having the same problem with mine. I also live on the edge of 4g area, so it was constantly swapping between 3g and 4g. In addition to using some data it was killing my battery swapping between 3g and 4g. Using almost 10% per hour when not being used. I disabled most of the verizon stuff, support and protection, Verizon navigator, caller name id, message+, and verizon location. I turned off facebook location reporting in the app settings, and disabled google location. I did all these a couple at a time and would reboot to see if it fixed the problem and after all those were done i rebooted and wiped the cache and the prblem was gone. I turned google location back on so far and its still working the way it is supposed to. It shows a greyed out 3g symbol and my battery life is much better. My phone sat off the charger all night and only dropped 4% and in 5 hours of moderate use its down to 77% left. Wish i knew exactly which app was causing the problem to help you out better but hopefully you can try those apps and settings and get the same results.
Well it worked for about 3 days, but this morning data and wifi were both running again.

Data usage Samsung Galaxy Note 4
Been having the same problem even when I disconnect data ten or fifteen minutes later data is back on. And I've noticed even if I am connected to Wi-Fi data trumps it and I end up using a ton of DATA when I've been connected to Wi-Fi all day, getting seriously upset cause I never used this much data before.

I have same problem with my Note3 running Lollipop. Have tried every suggestion I can find to turn off data, but it is still runs, unless I am on wifi. Data is set to off, 4g symbol in notification bar is greyed out, but data is still on. I have found forums all over the Web with other people with this problem, but no solution yet. My phone is unlocked but not rooted.

Wifi connection keeps dropping in Chrome - ERROR -->dns_probe_finished_no_internet

Hopefully someone here can advise me on this issue I have been getting with my Nexus 5x and using chrome but issue also happens in youtube. Note I have not setup my phone with a SIM yet, just been testing out the phone features and Android 6.0
When connected to my home networtk chrome and youtube work fine but every now and then the web page loading seems to stall in chrome, and then i watch the wifi signal disconnect and then reconnect and then the web page will load, but before it does i get the error message
dns_probe_finished_no_internet and sometimes its ERR name not resolved or ERR_NETWORK_CHANGED or similar inside chrome.
it seems to recover after about 30secs and then i have full wifi again. it just keeps happening This seems to be random at the moment but is consistent. My home network is pretty solid and all my other devices work fine and do not exhibit this issue, my wifi is solid.
I have done all the usual forget network, wipe system cache and static IP etc. nothing makes a difference. can anyone shed some light what might be causing this?
thanks

Did you manage to solve the problem? I got my phone last week and I am having the exact same problem.
I should mention that I am on stock unrooted and using At&t network. I checked the wifi connection from my older phone lg optimus g and it seems to be fine. It keeps on disconnecting and reconnecting on my 5x though and I think that is draining the battery faster than anything else. My top two battery uses are android system and android os rather than sceeen.
Do you think it is a hardware problem?

Have the same problem with mine after one week's use. Was fine until this morning.
On hold with warranty service now and will be getting a replacement.
Don't wait, use the warranty.

My problem was more global than just while using Chrome. Don't know if that matters....

Any luck getting rid of the problem? I even factory reset my phone but the problem is still there. My problem is also global, not just in chrome. I think that there is a problem with the wifi of the phone. I do not want to root and install a new kernel as of yet. Just want to stay on the stock rom.
What did the warranty service say? Is this a common problem with the 5x? I would rather not RMA if the problem can be solved by some other means. I put on the screen protector so well. Don't want to do it all over again lol.
Also, is Android OS on the top of the list in battery drain? It is for me and I think the wifi connecting and disconnecting prevents the phone from sleeping.

<----------------->
Tried everything, reset network connections and then tried a complete reset and attempted new setup but the wifi was too flaky to complete the setup. Since the problem happened while I was using the phone I was not able to observe the effect on battery life. I would imagine it would take a big hit trying to connect and failing continuously.
Did this before calling Google so I wouldn't have to do this while on the phone. Warranty Service did not mention any ongoing problem with the wifi.
Am setting up the replacement currently. I'll save rooting, etc. until I've used the phone for a good while.
Bite the bullet and send it back. It's not going to heal itself.

Hi guys,
Just updated to 6.0.1 OTA and yes the problem remains and seems even worse now. Can I ask how you go about the warranty? Is there a number to call google directly?

oops sorry I should have said im in the UK, dont worry il find it. Can I ask is your replacement phone working correctly now, no wifi drop outs as before? if so what version of marshmallow are you on?

I've only been using it about 8 hours but no problems so far. The phone updated to 6.0.1 during the initial setup.
You can find the phone # for the UK by using a 'Contact Us' link in the Devices Store on Google Play.

ok so I seem to have fixed this issue been having and it turns out the phone itself is fine. The issue was with 2.4Ghz wifi networks. There are quite a few in my local area and there is probably a lot of cross talk on channels. So i setup a 5GHz network and my n5x seems rock solid since ive connected to that. no one single drop out all day! speeds are also much faster im getting 150MB download speed on wifi lol...
i changed nothing else on my phone just for the record. hope this maybe also helps someone else

I think I have an issue with the college wifi as well. I asked my friends who are using the same wifi network and their phones also do not seem to remain connected. I thought that it was an issue with my phone but I guess it is not.
To test that, I connected my phone to my college wifi all night and when I woke up in the morning, more than 20% battery had been used probably because of disconnecting and reconnecting continuously. The next night, I connected to some other wifi and there was less than 3 or 4% drop in battery overnight.
I hope they upgrade the college wifi as the battery drain is very annoying.

Battery drain related to mobile data

Hi,
I used successfully lineage-17.1-20200220-UNOFFICIAL-serranoltexx for a while, it worked great, but for some reason, the phone started to drain the battery and loose 10% of capacity per hour. In the meantime, I could pinpoint the issue. The drain happens only if the mobile data is on, but even if I have a good, working Wifi connection. Using BetterBatteryStats, I can see that the wakelock "bam_dmux_wakelock" is waking up the phone very often, which confirms that the issue is related to mobile data.
I have updated to lineage-17.1-20200220-UNOFFICIAL-serranoltexx and the modem to I9195XXUCQL2, which seems to be the latest for me (Germany, T-mobile). It didn't help.
2G/3G/4G doesn't make a difference. With 4G, signal strength is about -100 dbm, on 2G, -70 dbm, which seem like reasonable values.
I don't phone often, but I have also issues with the normal calls: I cannot pick up, or the call gets interrupted. Maybe the issues are related.
I am out of ideas how to investigate further. Is there any way to see the reason of the frequent ""bam_dmux_wakelock" ? Could it be a hardware issue ? Any other idea?
Thanks!

You should address this in the topic of the rom you have installed

Thanks, but I did already and didn't get any feedback. It doesn't really belong there anyway, because I don't think it is a problem with the system. A lot of other users are happy with it, and so I was, until the problem started. It could be the modem, the carrier, a hardware issue... Therefore I started a new thread.

I bought another used S4 mini, and I installed the same system ROM, and copied the complete data over. I have now good battery life times again, more than 24h. So it was actually a hardware issue. The S4 mini are getting old unfortunately.
