Has anyone tested battery impact of VoLTE?
I don't get much signal at home so always using WiFi calling, and as such haven't been able to test standby drain with VoLTE Vs without.
In theory VoLTE should improve battery life as the phone doesn't need to connect to 2g/3g to make calls, but seen a few potential issues.
Anyone tested it out in controlled conditions?
Yes, I'm on VoLTE...no serious battery impact..infact, nothing at all..

I do a lot of browsing on my milestone, i predominately use 3g/HSDPA but wondered if using wifi is better on the battery life? Any views or knowledge on this?
It depends what kind of internate usage. For example browsing or some other active internate usage meant 95% of battery drain will be the screen+CPU, so it doesnt matter what you use.
But if we talk abaut constant internet connection in the backgroud i can tell you 3G/HSDPA uses a A LOT more battery than WIFI or 2G. I went from 2G to WIFI and no real difference. But 3G has some isues with constant connection, i think the reason is, there is no real low power mode for 3G. So either have WIFI, or only turn on 3G when you need and put back 2G, when you dont use your phone.

WiFi on this device is amazing. I use it at home and work and noticed a large boost in battery life, almost doubled my battery life.

yep same here
cheers guys will be testing wifi out over the next week and see if it helps the battery life!
Hmm, I was wondering. What is your battery life on constant 3G (web browsing, google talk etc.) usage and on stand-by mode?
The milestone's wifi is one of the less consuming wifi chip ever seen on a phone.
The 3g, instead is exactly the opposite, specially if you are on fast network (10 or more Mbps), specially if you are using an old FW.
My milestone was lasting in about 6h with the original FW.
With 2.38 it can cover a whole day
Hi folks
Does anybody else also expierience such a huge battery drain on his One? It runs smooth and the battery usage is acceptable, but as soon as i turn on a faster network than 2G and surf on the internet, especially searching for things (loading data), it's using so much battery... I know that the screen is on and the cpu load is also higher while browsing and i was expieriencing this problem on my other htc phones, but it seems like a problem with the modem for me... it gets hot while browsing and is using more battery even when in idle
Is your phone rooted? Have you checked whether some mod or something is doing it? But if you want better battery life with LTE you can always enable fast dormancy if your carrier has that. But also if you have fast dormancy already enabled try to disable it because some carriers do not support fast dormancy. Best way to check, call them up. But over all I'd say that on LTE it should get a good 5-10 min per 1% battery drain. Hope I helped

I've been running marshmallow since the stock images were posted and I always got very nice battery life with doze. As in, I wouldn't have to charge the phone until the next morning. Since last week, however, cell standby is using significantly more battery. Yesterday, I took the device off the charger at 0900, and by 2100 I was already at 25% battery. Screen on time was only 2 hours, and cell standby had more usage than the screen. No matter my signal quality, it seems cell standby is eating my battery. Phone isn't even showing as awake! I also am always connected to WiFi and using T-Mobile WiFi calling.
I know a few users have reported a similar issue since marshmallow, does anyone have an idea of why cell standby is killing battery even though time without signal is 0? Time active is also always under 20 min. Since I'm using WiFi calling, I'd think the phone wouldn't even be searching for a voice signal anyway.
My signal has been worse than abysmal since switching to Marshmallow. I uninstalled Fit, Pay, and Google+ and it got better strangely enough but i still have issues from time to time...

The same happened to me, at the begining with marshmallow (chroma and francokernel) always more than 5h SOT and easy deep sleep... but now, the last night at 1:00AM battery was at 100%, at 5:00AM was 84%... and no wakeloks... i'll take some screenshots
Same here. I swear the battery is draining faster but no wakelock issues.
Plus I believe there is an issue with the signal reporting. Where I know that I get full signal the phone can report zero bars. Switch to airplane mode and back, then suddenly the signal displays correctly!
+1 My signal is terrible anymore, and I certainly was much better on the preview images
At my desk at work, same spot I sit my phone everyday would be in the mid 80s and right now it sits at -103....hit airplane mode and it resets....for a few

I'm having the same issues. Overall, pretty solid battery life but cell standby drainage was high. Been searching forums with no such luck. Sounds like it might just be and Android issue I have to hope gets fixed in an update? I'm using T-Mobile wi-fi calling. I'm in areas with strong LTE signal, but compared to my old phone, the amount of "bars" I'm seeing seem lower and sometimes non existent, although I spent no time without signal.

Does turning on wifi calling when in a low to moderate signal area help or hurt battery life?

It can't hurt .. doesn't necessarily help alot but turnoff it off isn't going to drain any worse .
A battru saver idea i use is go to phone/ more/ settings and disable volte
Which is voice over lte.

Hey, I noticed on my new GT2 poor standby time, somewhere I read that it might be caused by VoLTE is this possible?
Try using settings > battery > advanced settings > app quick freeze and select apps that you don't neet to run in background.
I did that but I continue having battery drain, only 3-4h of display time.
Well I have to check this tomorrow but it seems that VoLTE is a problem for me.
might not help you too much
but for me, with VOLTE turned on the SOT is pretty good
like 7+
In my case, with VOLTE off and all apps with quick freeze I have less than 4h of SoT, what I can do?
PD: screen at 120Hz, of course.
i mean its super hard to give any recommendation
it really depends on the apps you are using
if you are gaming with 4h SOT it drains much more than if you are just browsing
take a look at what drains your battery and try to optimize there
I have Wifi on and only use the phone for emails, web, whats and calls. Never playing or heavy tasks.
also if your signal strength is not optimal it burns a lot of battery
if you are having 5g enabled but no 5g contract or 5g in your area, disabling 5g is also saving something because the phone stops to constantly search for 5g
For me - on 4g network, with VoLTE off is better - screen 120 Hz. I also switched off those options to report customer experience.

I have signal off, only wifi and 5g off.
It is much better - for me without volte option ON (I read somewhere in review of different phone that snap 888 dont like volte sometimes maybe it is also firmware related problem ) - 4 h SOT and still 55% battery , mixed network 1/3 wifi + 2/3 4G . With gps off .

At 120hz?

yes + auto brightness + AOD on (black theme)
Then I have battery drain problem, how I can fix it?
Please understand that SOT will never be the same between uses. And should never be compared between users, we all do things differently with our phones. And, also, if anyone mentions his SOT please mention the total usage time, like I have 2days usage, 3h SOT, 30%battery remaining, and this are generally good. You can't have 6h SOT and 2days usage, but you can have 6h sot with 10h total usage and 0% battery remaining! And post screenshots that sustain your affirmations.

Man, yesterday I got 1h 10min of SoT with 9h of phone use at 50% of battery, as I said, I only use the phone for emails, web, whats and one call of 4min, always with WiFi. Its evident I have a battery drain problem, indeed, in idle the consumes batery all the time, my old realme X2 had better battery administration 3 years after I buyed it.
I cheeked all the permisions and syncronitzations and is all ok, maybe the only solution is a hard reset...
My data from last day with VoLTE on my phone needed charger about 7pm without VoLTE about 11pm.
After few days I confirm on firmware A14 - VoLTE eats batter like crazy :/ - how to report that to Realme - their forum don't look good at all :/
Try emailing: [email protected] I've sent them emails about some issues, got some replies but didn't solve anything... Try your luck )
