Hey guys .
I have an S6 Edge SM G925F
I leave my mobile network set to WCDMA/GSM (auto connect) .
Signal constantly changes from H to H+
Would this be reason I'm getting bad battery drain while device is idle ?
And if I have a 4G connection with 1 bar signal would that use less battery than the constant changing H, H + signal ?
I'm on 5.1.1
Am not rooted.

Can post a screen shot of your battery usage? IF the Cell Standby percentage is high than you would need to uncheck some settings under 'Data Usage'. I have a G925A so the settings are a little bit different. The things you should uncheck would 'Calling over Wifi only' and change it to 'Perferred Cellular Nework'. Hopefully it helps.

This is normal behavior to save battery.
The device reverts to H when no significant data is going in or out because maintaining H+ connection unnecessarily can cause battery drain. The phone is able to do this rapidly as data goes on and off rapidly. I believe H is the normal always-on connection and the H+ is the extra speed that's only active when there is actual data transfer. This behavior is called Fast Dormancy and exists in maybe all smartphones. There are ways you can switch off Fast Dormancy using secret codes and some believe this improves battery life. I don't know because I never bothered with it. There are countless articles on this, I'm sure you'll find more information on this easily.
As for the 4G issue. Holding a 4G connection when reception is low also causes battery drain which is why the device reverts to 3G/H/H+ instead. When reception is low, whether 3G/H/H+/4G, the phone has to deliver more power to the antenna to hold a connection.
I have a 4G plan, but because 4G reception is not as widespread and strong as GSM, I have turned off 4G on my phone to save battery.

Thank you for your feedback.
I'm pretty sure that viber is the main cause of my standby battery drain.
I disabled it and whoopy yesterday I got insanely good battery.
Seems like it's really using my cpu during standby.
Thanks for the info.
Am also going to try to find the secret codes to disable H/H+ and see if that helps .

There is no such secret code. The only way is with SU permissions.

Is there any way to always keep it H+ instead of switching? My voip calls are dropped and internet gets stuck because of this switching. Even when using internet actively, it goes to H and ruins everything on my K3 Note.

everyone knows that using 3g as opposed to 4g when u have a choice saves a significant amount of battery life. but i read somewhere that it's possible to set your phone to use 4g ONLY as opposed to 4G + 3G if 4g isnt avil.
For people like me who live in LA, 4g is almost everywhere. That same article said that if you go with 4G only, the battery life used is almost similar to 3G only, since it's not constantly looking for both 3g/4g signals. can anyone confirm this?
i use an app called "LTE OnOff" And it 1 click takes you to a screen of options between:
1. 4g only
2. 4g & 3g (CDMA)
3. 3g (CDMA)
There's also *#*#4636#*#* for those who don't want to use an app to access the menu.
I just put mine in LTE mode with voice. I am gonna see how that is tomorrow.
I posted this app in a couple other threads. You will still incur the same battery drain with 4G+Voice as you do with 4G/3g.
oh wow okay, so then that option is pretty much useless... theres no real advantage to going 4g only i guess...
thanks for clearing that up, much appreciated.
on a side note, is a true that using launchers increases battery life roughly 20% or so?
im considering going with go launcher ex
I paid for ADW Launcher EX when I had my X2. I haven't taken the leap because I enjoy Sense right now. Someone else may be in your shoes though. Let us know in a couple days if you see a difference.
I have several times switched to 3G only on days when I was out all day in an effort to increase battery life. I saw NO improvement on 3G only. I still saw 1-2% lost per hour in standby.

are you sure? because couple posts up, AtLemacks says:

You can always try the free version of juice defender, that may help.
Nope juice defender doesn't really seem to help either. As an experiment, I put my phone in airplane mode, off the charger, overnight one night while I slept. I STILL lost an average of 1-2% battery per hour.
It's weird though, the first 10%, from 100 down to 90%, will drain very slow. Once it gets past 90%, it drops rapidly, even in standby, regardless if I'm on 3G only or LTE/Voice or data off it doesn't matter.
I don't see the problem with leaving it on 3g/4g I only saw a battery drain problem when switching between both. being in a solid 4g area, I am amazed at standby time. It seems to almost not move. The phone will never standby completely lossless. 1-2% an hour? That is not bad at all. That is over 3 days. I've done 3g stuff, 4g stuff... Never noticed a difference. Big users... GPS. then netflix streaming. But those make sense because more is on, and netflix is full bore usage.
Even then, I go through 30% in an hour of streaming.
Obviously you're never going to have no battery drain on a device that is powered on because it constantly requires power to keep data in the RAM (unless NVRAM is used). 1-2% drop isn't bad at all, that's probably the least you're going to achieve.
my Incredible on a 1500 mah battery (stock EVO battery), running a leaned stock group ROM and Chad's incredikernel would lose 1% every 2-3 hours in stand by. If I needed to stretch it I would turn data off and go 4 hours before dropping a percent. I don't understand why this phone drains so much in standby even with data off. With the phone on and doing stuff on 4g sure, I never expected the battery to last like my Inc, but 2% an hour in standby with data off sucks.
I would hope that w/ 4G+3G, the phone would really have the LTE radio on for data and the 1xRTT radio on for voice, and only fire-up the EV-DO radio if LTE drops out.
With LTE+Voice, the phone probably does the same basic thing, since Vzw doesn't have VoLTE yet. So LTE radio on and 1xRTT radio on. So the only difference between the two is probably if LTE drops out, instead of firing up the EV-DO radio, you got stuck with 1xRTT for data. So if you're in a strong LTE area, you probably won't notice a difference between the two.
Although this is just a huge guess on my part.
My old MT4G when in airplane mode (and no apps installed) ran over 24 hours and only dropped 1%
I did this as an experiment as I knew I was selling the phone to my cousin the next day. It dropped the 1% after I handed it to him and he was messing with it.
All the phone had was CM7 and a good (non cyanogen) under-volt kernel that defaulted to a governor that had a screen off profile built in. It had been factory reset as well. A good ROM and kernel really helps, this just goes to show you where the real power drains are.
What this tells me is that these phones have the potential to have great standby time but for the radio and account syncing. (and any poorly written apps that cause the phone to enter an awake state too much) That is one reason that I am excited about the new S4 chips that have all the radios built in. That should help power consumption from the radio in general and even more when the phone is idle an not transmitting.

I have just created a profile in Tasker where if I'm on a wifi, it automatically turns off mobile data. Once I turn off or lose the WiFi connection, it turns mobile data back on. I used almost zero battery last night for the first time since I've owned this phone. I might experiment with turning wifi off when I leave the house with another Tasker profile, too, so wifi doesn't pull juice searching for signals and hotspots. Here's to hoping this helps extend battery life; all signs so far are that it's working.

If you are in an area with weak signal, you will kill the battery faster.
The radio will ramp to maximum output and that burn battery.
Phone batteries last longer in strong signal areas.
If you are in a bad area, turn off radios to preserve battery.

I don't think that it does. I've never had virtually flat battery use lines at night in any of the past 2 + weeks. There's always a steady drop and I can now attribute that to mobile data doing "something". It says it's disconnected when you're on WiFi; however, the 4G symbol is still highlighted. When I use tasker, it greys out. For some reason, I believe it's still maintaining a slight connection to the network for location or some other unknown reason. I could be wrong, buy my perception now is that this is working. I'll know better in the next few days.

this is something that has bugged me since I got this phone, my last phone was a Droid Razr Maxx and when I used the Motorola Smart Actions to disable data the 3G/4G icon would completely disappear from the status bar, but when I toggle data off with the pull down menu on the G3 I can still see it switch between 3G and 4G icons and even with both DATA and WIFI off the 11c update was still downloading and I had to keep killing it till I was able to root, so it's like it disables apps access to the data but doesn't actually power the radio down all the way.
Another thing was when I had mobile data off on my Razr and someone sent a Picture message (regular text and calls came thru fine) I would get a text with a download button on it where I would need to turn data on then download it, but on this phone it just comes straight thru.

I ran into the same issue with my S7E during the first week I had it. Then a update was released and the WiFi issue went away. But yea, it was draining my battery and making my device get hot even if I was just browsing the Internet.
Maybe it's a problem with Marshmallow.

I do not have anything syncing over WiFi, at least not frequently. Also, changing the switch to mobile data setting does not help my problem. When on WiFi, the highest battery user is "Phone Idle." The issue has seemed to be less prominent over the past few days, but WiFi does still use more battery than LTE.

Interestingly, it appears as though my WiFi battery drain issues are related to a particular network I connect to. For other networks, I don't seem to have the problem. I have no idea what the difference is.
Is it a 5ghz network by any chance?
On WIFI all day long and my battery is draining very slowly (1% per hour when idle) BUT i am not on a 5ghz wifi network.

At home I am on 5G and I don't have any abnormal battery drain. When not at home I am on LTE.
Anyway, the only drain problem I experience appears to be associated with use of Google (Now) and/or Chrome. Haven't narrowed it down yet. And with those it is on either LTE or Wifi. When I get the issue I have to force close the apps and reboot to get it to stop draining at a fast rate. At least that is what it seems like. Only had a couple occurrences since I don't use those apps too much.

I don't see the problem there, when selecting a wifi ID, just select ID with 5ghz.
My router is/was configured with a shared SSID for 2.4 and 5 ghz... It always defaults to 2.4 instead of using 5 as a preferred connection. I had to separate my router SSID for it to work.

Many router will default to 2.4, as the signal is much strong, your only way is to forget the 2.4 for it to auto connect to 5ghz, but for a phone 2.4ghz is probably much better.

It's very good. Though it's 3000 Mah but it lasts​ for a day on normal (moderate) use and about 15-16 hours on heavy usage. All of these is because of SD626's optimisation of battery. It's very clinically done so there is no unnecessary drainage of battery. It's standby time is also good.
Wow, that's better as the old Z Play. But with bigger battery it would be absolut amazing :laugh:
I was on pace for about 6.5 hr SOT yesterday, mostly just browsing with about 30 min of gaming and 15 min of maps.

Cell Standby battery usage goes up as the signal strength goes down. The phone cranks up the power to maintain a signal.
From your picture, it looks like you are at 1 or 2 bars on the meter. That's what I get at my work and that's where standby uses the biggest chunk of my battery. At home I have close to full bars and standby uses a lot less battery.
It's quite enough for me, I remember on my z play I got more SOT but z2 play is definitely not bad, plus it's multitasking faster due to the 4GB ram.

I also get 6 to 7 hours SOT during my tests, compared to 3 to 4 hours on my Nexus 5x.
But there is one area where the Z2 Play is surprisingly bad. The LTE signal strength is pretty weak. With the Nexus 5x I get consistently "5 bars" at home and just 2 bars with the Z2 Play. Which means I have essentially a yellow/orange dotted in the "Cellular network signal" battery history. I am wondering what difference a 5 bar LTE signal would make (in terms of battery life).
Most likely this signal strength difference can be explained by the different modems. The Nexus 5x has an x10 lte modem. The newer Z2 Play has only an x9 lte modem. To address this problem the 626 features TruSignal antenna boost technology which is supposed to optimize reception in weak signal strength conditions. But apparently it doesn't work that well?
Does anybody else have similar LTE signal strength issues?
Screenshots ...
Just revising my SOT ...
I consistently get 7-8 hours with low 4g signal strength (wow!). Really impressed.

I don't think anymore that this is a modem issue. I was able to compare with an Oppo R9S which also has an x9 lte modem (snapdragon 625). But the 4g signal was excellent on the R9S ...
I'm getting mobile standby as my largest drain as well, even though I have full signal strength 100% of the time. Seems to be quite high to me.

I'm also having the same cell standby issue. I'm always struggling to get to 4 and a half hours of SOT, because cell standby is always at the top even with 3/4 bars of signal. I can't live with this. I read in the Motorola forums and one of the solutions they say is to recalibrate the battery. To do that, you have to press the power button until the phone restars and then charge it to 100% percent. I will try it for a couple days.
Hey guys,
I just got an S9 plus exynos version a week ago and the battery life is horrible with me only getting around 2-3h SOT.
Any tips on how to improve it? you can see the stats here:

Just have a look at the below videos. Unfortunately, that's how the batterylife & performance of the Exynos version is, just like mine. Unless you tweak it with so many tweaks and workarounds(search the forum, there are many tweaks if you like to consider) like many others here, there isn't much hope unless Samsung seriously considers resolving this which is unlikely.
Yes it is correct the battery life on this s9plus is pathetic,
Even on my phone the android system is taking major amount of battery ,
I tried factory resetting my phone a few times but no luck .
Waitng for an update from samsung

In a statement, Samsung indirectly said that "the bad battery life is a non-issue", so an update isn't coming soon...

Strange I get about 2 working days of battery life.
There is definitely a lot of bloatware running in the background though, have you tried running KillApps?

Your Android System is particularly high at 21% compared to your SOT.
Noticed that you're on 3G, it consumes battery a lot more compared to 4G.
How's the mobile coverage at your area?
The exynos version of this phone sucks big time, I can tell the battery life is horrible Max 5 hrs SOT. I have switched to xz2 xperia and it beats Samsung hands down in every department. Batteries are amazing.

There won't be any update from Samsung for sure. I sold this terrible phone. Samsung software optimization is very poor. On my xz2 I don't do any software tweaks.

Not the best I've experienced, but also not too bad

my cpu frequency is stuck at 1.79 and this is why my phone is lagging and heating and draining battery .
is there any way to check what is spiking the cpu so much ?
i checked in cpu process app and it says system server is taking the cpu .
any technical person who could help .

I thought LTE consumed more battery than 3G... The reason was a problem with the network. Fixed now so I'm back on 4G. Lets see if it makes a difference
Well love the phone but the battery is the worst I've seen so far for the price u pay. People focus o SOT time but I do the same as on my old iPhone 7 plus but with the iPhone would last from awake to bed time with one charge S9 plus 2 times at least and with though about running out all the time. Shame brilliant phone.
I'm having great battery life on my Exynos 9+. See the attached screenshot.
Only disabled Bixby and AOD.
I use Facebook, Messenger, Snapchat, WhatsApp, GPS high accuracy and sync one Gmail and one IMAP.
For testing purpose I decided to run the whole day with medium battery saver activated, but modified to only restrict the CPU and lower the brightness a bit. That means still running max. resolution and syncing in the background.
Right now the phone still has 36% battery left with:
- 18 hours 33 minutes since unplugged
- 6 hour 30 minutes SOT (That is potentially 10 hours SOT with 24 hours since unplugged!)
- 10 minutes phone call.
Besides my regular usage pattern, I've also played a game a lot on this charge.
No complaints here yet, im getting 5hrs SOT and have only done a few charge cycles so i expect that to improve.
Im getting close to what i do on my pixel 2 xl so in my eyes thats impressive

I had an Exynos S8+, and battery life on that was pretty bad, with Android System also taking up more juice than the Screen. Now I'm on a Snapdragon S9+, and dare I say battery life has almost doubled. Android System battery usage is way below Screen battery usage.
Two steps which fixed the battery drain for me :
1. Changing the Location Settings from "High Accuracy" to "Battery Saving" {You can find this in Settings -> Connections -> Location}
2. Using 2.4Ghz WiFi instead of 5Ghz WiFi channel. My Router is a Dual Band Router and somehow when I connect to the 5Ghz Channel, the battery drain is almost doubled. Sticking to the 2.4Ghz Channel improves the standby time by quite a lot.
Hope this helps.

Where can I find the ability to switch this Wifi frequency to 2.4 GHz? thx?
The culprit is most prolly Google Play Services.
today's update ... jupiiiiii .... Exynos (Slovakia CSC: ORX / ORX / ORX / ORX)

It's router specific. It only matters if you have a DualBand Router and you opted to connect to the 5Ghz Band.
