If I am using 3G on then phone heats up - X Play Q&A, Help & Troubleshooting

I am on MM, upon moving to MM I could notice that the phone heats up on 3G data mode and battery drains fast. Mobile is not rooted.
Any solutions?

100% time without signal - strange and serious bug detected

After 48 hours of usage, gsm signal dropped and returned randomly.
Tried switching 3g/2g, turning flight mode off and on.
Checked battery usage "cell standby" consumed the most of the battery. Strange "100% without signal appeared"
Rebooted the phone by switching it off completely and on. And... It's flawless again. Perfect hsdpa speeds.
Looks like serious software bug to me in latest XEU ROM or radio software.

This is what suppose to happen.
Cell Standby and phone idle will show most battery consumption when phone is idling most of the time. Basically thats the nominal amount that phone will need just to stay powered up.
This is normal.

100% time without signal and loosing gsm signal all the time are not normal.
It, wasn't a network problem. Everything happened at the same location.
Only full reboot helped.

No, thats not normal, but in absence of the signal, its normal for those two to show most usage.
Your phone might have failed registration on your network for some odd reason. If it does not happen too often there is nothing to worry about.

Agreed. It wasn't able to register to network again until rebooted.

It happened again after 24 hours.
Lost cell connection. Nothing helped. The only way is to reboot.
100% without signal is known bug in ginger bread.
"100% without gsm signal" means no signal at all or wcdma signal instead of gsm signal all the time.

Did you fix it?
I got the same problem
Are any of you using one of the XXKGx Android 2.3.4 firmwares?
If so, try installing an older modem file; that may fix the problem
For everyone with the 100% w/o signal
Please share this.
Go to settings>About Phone>status....and then go back.
Check the stats afterwards, you'll see the counter decreasing.
it's not a serious bug. it's just a log bug.
Hi,
I've fixed this problem changing a mainboard in the maintenance assistance and upgrade the firmware as well

i9505 draining too much battery on 4G

Hi guys. My Galaxy S4 is draining too much battery when 4G is enabled.
It runs warm 100% of the time and it drains 10% every hour on idle and even more when I start using it.
Once I disable 4G and let it only on 3G the phone goes back to normal temperature.
It drains only 0.5% every hour on idle and lasts for a day with 4h 30min screen time. I can't do that with 4G enabled.
I tried stock ROM, Cyanogen, Google Edition. They all have the same problem.
I would really like to enjoy my 4G 100% of the time but at this rate it's impossible.
Does anyone have the same problem or is it a hardware fault?
Thanks in advance for the help;

My 4G signal is very strong most of the times and I get 80mbps of download easily.
I just wish I could use it without draining too much battery.
Actually, what bothers me the most is that it drains a lot when idle which it shouldn't.
Do you have sync on? if u have a lot of apps syncing maybe that can happen ... tbh even on wifi with sync on u get increased battery drain evenwith just google apps syncing let alone in 4g which is already power consuming as it seems ...
Had the same problem in Germany. It's caused by 4G, fallbacks to 2G if you call somebody and by the search for other cells by the Galaxy S4. I also switched to 3G and have an awesome battery time.

My experience is quite the opposite. With 4g on, standby time is amazing. 1% in 2-3 hours. Same as with the S3 4g which I use as a second phone.
Before I got a 4g phone I was really worried because I read that 4g uses more battery than 3g, but for me had been the opposite.
Maybe try a factory reset or flash another rom. 10% is way too much.

You are on "stock ROM"?
try active only 4g to test, maybe is falling sinal of 4g to 3g or 2g is drain your battery

Using Ripper rom + Perseus kernel on the S3 4g and stock but rooted and some mods on the S4. Signal strength also plays a big part but still, 10% an hour is too much.

Hi, I guess my battery life's improved significantly after the Lollipop update. I think you might need to reinstall Lollipop.
Mine is draining a lot faster too.
Did a full wipe.

Me too, no problems, perhaps even a little bit better battery life than on Kitkat.
Same here no problem. Flash stock again and then restore the backup.
No probs here also!
Try going to Recovery (TWRP/CWM) and do a Full Data Wipe and Clear Caches and Wipe Dalvik Caches also.

Even i was facing problem with battery, battery was not lasting even for 5 hours. Which started after i upgraded my moto G to lollipop. Fortunately there was no issue with lollipop updated and issue was caused due location service which uses GPS radio (which uses more battery power), turned off the location (slide from top of screen and turn off location) and issue resolved.
try this: https://www.youtube.com/watch?v=mxrcUs3-wGg
good
great advice, battery is quite stable after a full wipe cache partitions, previously, wifi and awake were always on and consuming battery fast. now every thing is ok.
my battery can hold a screen on time just under 5 hours. ( With between light and heavy usage ) I use apps like whatsapp, facebook, 9gag and the local news app a lot. Maybe your battery is not calibrated good? But what i did notice is that from 100%-50% it drains much faster then from 50%-0% battery. wich is kinda strange.
my battery faster discharge between 100% to 90% .. .. O_O" !
Try to set the CPU Min clock Range to 300mhz. Should work

hi can u plz give me some info about ur lollypop plz
Mostly caused by apps waking the phone for background data.
You can restrict all background mobile data by going to:-
Settings, Data usage and slide the mobile data switch (top right) to off.
Tap the menu dots and tap show wifi, or tap the WiFi tab.
You will then have a long list of all your installed apps on which you can turn mobile background data on and off as you require.

Option to turn off 5ghz WiFi in Samsung?

I feel like 5ghz wifi is draining my battery.
My 4G connection has been fine with minimal to zero drain when idle.
Anyone?
I noticed this too before the PC8 update. After the update I don't notice it anymore
