Hi all,
I have this issue that my 3G mobile signal drunk a ll the juice of my battery.
I tried every rom including the latest Android L preview. With every rom I could only survive only 3 hrs of screen time. If I leave it completely not using. The standby time is still within 8 hrs. I used the fastboot to reflash the factory image and replaced the radio version but it didn't help. A brand new battery was also replaced.
I believe it is the modem problem because if I turn on the airplane mode, the battery works great even with wifi on.
Any ideas?

That sounds about right for the Nexus 4, thats what I have been getting on mine since I got it. A custom kernel helps the most with battery, but don't expect huge gains
whats your service provider?, signal strength could be the issue.
have you got any betterbatterystats logs?
Hey there!
I flashed the official Lollipop (Germany) rom that is posted in the Note 4 General forum two days ago without doing a factory reset. Right now, I am experiencing horrible battery life. GSAM reports that the phone radio is using 35% of the battery life. I also see the 4G icon blinking every few seconds, indicating that mobile data is being used. How can I solve this? My battery life was perfect before flashing Lollipop...
Many thanks in advance!
Screenshot just in case:
Maybe you should try a factory reset.
Although I updated without resetting and one of my friends did a full wipe before and after, and we both see a decrease in battery life. Nothing too horrible, but noticeable. So I think it's just Lollipop. After all, even the Nexus devices have been having battery issues with it.
See if a factory reset helps you, worth a shot.

Thanks for your advice. I will be sure to give it a shot. A decrease in battery life is pretty bad if you ask me. I thought Project Volta was supposed to improve battery life, not decrease it. And definitely not as much as is happening to me. By the way, the phone radio is still constantly active. I hope a fix will be out soon.
Can you check your Power Saving menu? I have similar problems with all apps that are using mobile data. Their Total connection time is really long even though I have used them for a few minutes.

Unfortunately a factory reset didn't help. My battery is still draining way too fast.. I can get around three and a half ours screen on time. Previously that was around five hours. I will check the total connection time later on when my battery has drained a bit!
Horrible battery drain in my handset, too. 910F model with German rom.
Flash echoe lollipop rom.waaaay better then stock.no more battery drain for me and much faster!
Formating cache partition helped me to get rid of the battery drain.

That sucks. It seems like this is a very serious bug in Lollipop. You'd think Google would have it figured out in 5.0.1 but that doesn't seem the case. Very annoyed by this.

hellO!
here the same battery drain of facebook after lollipop upgrade (germany)
when i unplug wifi it starst keep stay connected to facebook and it grows even bigger than screen battery consumption.
heve you fixed it?
thanks!
I found WiFi to be the culprit for the rapid battery drain on Lollipop. Check out the following posts with my observations so far:
iridaki said:
After updating to Lollipop, I found that the phone behaves very differently. I have high "stay awake" times, caused by Android OS, even on Ultra Power Saving Mode. However, screen on time is still close to 4 hours, which is what I was getting on KK with my usage.
Before people jump in and say I need go factory reset, no I don't, there's another Note 4 in my home right now that was wiped before and after the update and shows the same symptoms.
Also I did install Gsam, but I'm not rooted, so it didn't give me more information than the stock battery stats page.

UPDATE: I think I found the culprit. It's the WiFi. What I did today was charge my phone to 100%, switch WiFi off, disconnect from the charger and reboot. Then went about using it as usual, only I didn't turn WiFi on at all, not even for a second (weirdly enough, the battery stats report WiFi being on briefly at times, but that's another Lollipop bug).
The results were a big increase of SOT (+1 hour, see my previous post for comparison), no more permanent wakelock and increased standby time.
My findings are consistent with reports from Nexus users, claiming WiFi on Lollipop is a battery killer, even on 5.0.1, which was supposed to be an update to fix said issue.
Now, not turning on the WiFi is not really a viable solution for me, as I don't have an unlimited data plan, so I sure hope Samsung will fix this problem soon.

Below are screenshots showing battery behaviour with WiFi on (first 3 images) and with WiFi off.
It's important to point out that simply turning WiFi off doesn't appear to bring battery drain back to normal.
Turning WiFi off and rebooting fixes the issue, so long as you don't turn WiFi on again.

LOLLIPOP
I've started to have very poor battery life 7 days after installing the DBT lollipop. 60% after 4 hrs use today. It was good at first but has been getting worse by the day. Something was making the phone get hot just now so restarted and its cool shortly afterwards. However I cannot identfy what it was causing the overheating.
Is it worth trying to wipe the cache? I did a factory reset after the install as it was boot looping. I really do not want to reset it weekly! Google is crap at backing up all the apps - 160 out of 196 were reinstalled after the factory restart. Very poor.
Hi there ..
I have the note 4 N910c since 3 months now .. battery life is horrible .. I barely get 3-4 hours screen on .. when I use data network (3G) I can't get through the day until a second recharge ..
even after updating to Lolipop 5.0.1 .. at first little improvment then awful battery again ..
I uninstalled facebook, messanger, and some aps that work in back ground .. always disapleing location .. Auto Brightness ..
so, what should I do??
Same issue. N910C. Lollipop. I used Battery Doctor and found these apps running and consuming a lot of power.
Have you tried a factory reset already?
Try this

As i can see your phone has many wakelocks, i recommend a factory reset.
Thanks! Factory reset didn't stop the apps from running. I'm sure they are there for a reason, but they are consuming so much?!
Any ideas?
I am using Note 4 (N910C) bought new 4 months ago but some times device behave weird. Sometimes device stays awake (cpu stays active) while screen is off and the device is not being used. When this state happen in the battery stats it can be seen that the awake line becomes strong and permanent and only solution is to restart the device.
After restart, device behaves normal for about 2 to 3 days and after that same problem persist. During this situation 4% per hour battery is consumed when device is idle.
In battery stats Android System and Android OS consume most of the battery when this problem happens. Otherwise device consume normal battery and I get about 6 hrs of screen on time.
I have tried several solutions like
Cleared cache.
Disabled some pre installed apps which i don't use like svoice etc
Disable sync services
Installed Gsam battery monitor but no-special process found other than android aystem which consume battery in problem state.
But nothing mentioned above really helped. The only known solution is restarting the device which help for like 2 days and problem comes again.
Device is not rooted and I am using original Samsung OS. Lollipop 5.1.1 and Marshmallow 6.0.1 both have same problem the later was updated via OTA. But nothing addressed the problem.
Please guide with the possible soultion?
I have the exact same problem, would be great if somebody can help

I also have the same problem, i'm going to search deeper in the forums if someone solved this months ago
So far it ends up wasting the battery of a generally idle device and stays up long enough for my screen and body to heat up when left unattended.
Have you already fiddled with the screen settings itself? Particularly Settings>Device>Display and Wallpaper > Smart Stay? I turned mine off and it did reduce some of the battery drain issues.
WiFi and mobile data (even just the plain mobile signal) seems to drain the battery too a little quickly.
Hello,
So since .152 firmware got released i've noticed a considerable difference in battery life, have any of you noticed the same ? I saw some posts on the Zenfone 3 forums 2 people having the same issue and solving it by factory resetting the phone...i don't really want to factory reset my phone however, is there any solution to bringing the old battery life back ?
My apps or usage have not changed from before.
I noticed the exact same. I'm planning to revert back to 140. 152 causes considerable battery drain compared to 140.

How do u revert?
Some way to "block" update notification and popup?
I have had my zenfone for a month now and I have updated it to the latest firmware (WW_Phone-13.20.10.152-20161222). I must report I have no such issues, my battery drops 0-1% at night. I don't lose any battery when I'm not using my phone and I get around 7 hours screen time. What is it like for you? How much does battery do you lose at night? If you don't want to do a factory reset, try reseting your cellular network settings (Settings>Back up and restore>Restore cellular network settings). Then put your cellular network to 3G (4G uses more battery). Please reply if this helps. Good luck!
