I've recently purchased a RMN6Pro. The battery life is pretty good until I enable wi-fi hotspot. On enabling hotspot the battery drains very quickly. This is strange, as I didn't have such an issue even in my old Note 3. Is anyone aware of the issue here, and are there any known fix for this?

Since I purchased my first HTC smartphone (a Desire Z) I noticed that turning on the Wifi draines my battery very fast (charge 100% and after 4 hours only40% remaining with screen off).
I searched xda for similar problems and found some possible solutions but they didn't help.
I turned off auto sync, automatic date/time adjustment, putting the wifi in sleep when not using the phone.
I was so frustrated about this so I bought a new HTC. A Sensation XE. And the most frustrating thing is... It's having exactly the same problem!
It looks like whenever one of these 2 devices have Wifi enabled AND connected to my wireless network at home, the Wifi radio sucks my precious battery load very fast!
I'm pretty sure there is few data transmission when I have Wifi enabled.
I did following test:
- With original ROM (2.3.4) the battery took 100mA in stand by and wifi OFF.
- With original ROM (2.3.4) the battery took 450mA in stand by and wifi ON.
- With ICS ROM (4.0.3) the battery takes 50mA in stand by and wifi OFF.
- With ICS ROM (4.0.3) the battery takes 500mA in stand by and wifi ON.
Both tests were over a period of 5 hours and with Wifi enabled there was 2-3Mb off data transmission during that time.
A friend of mine has a cheaper HTC phone with less battery capacity and has Wifi AND data on all day and has a battery stamina of 2+ days.
Another thing I can say is, that when Wifi is enabled and NOT connected to a wireless network, the drain is way lower!
Can somebody tell me what I'm missing here?
It can't be too much asked to get notified in time when receiving mail on my 500€-smartphone, without constantly enabling/disabling the wifi connection myself, just to get the day through with one battery load?
Not sure if you got this sorted but I was having some issues with wifi draining my battery after flashing a new ROM. Not as dramatic as you mentioned but still very noticeable. Narrowed it down to wifi "best performance" being enabled by default, disabled it and saw a big improvement.
If that doesn't help or isn't enough, check your wifi sleep settings in the same spot too.
Does the hotword detection of google now always on or NFC checked on or LTE vs HSAP+ (while connected to wifi or not) or leaving wifi on even when not connected (like when out and about and not at home) affect the battery in a significant way?
Sorry if this is a stupid question I just wanted to clarify because Ive heard various conflicting things on some of these.
Thanks for any help to this question and if anyone has tested any of these and can give there feedback I'm sure it would be greatly appreciated!
LTE if you don't have a great signal will use significantly more battery then HSPA.
Hot word detection on will use a little battery but should only do so when the screen is on.

All of those things will use more battery. I've turned off NFC and hotword detection because I don't really use them. To be honest, I still couldn't tell you if it makes a significant difference, but I'm happy with battery life.
Location settings off, NFC Off, LTE off when not needed, connect to wifi whenever possible, Lux auto brightness app, Battery doctor app, and install a custom kernel. That should help you out a lot with battery life.
NFC and hotword detection make such a negligible effect on battery life.

I want location settings on with google now I dont want to cripple my phone completely or have to be switching things on and off constantly. But I will probably be switching off LTE for HSPA cause I seem to be getting a better signal and NFC off cause I dont really use it. I already have franco installed which I know will only improve in time!
How about Lux is it a low power process running in the background and do the savings outweigh that? and do you have the free or premium version?
hi there, i would like to share my mobile phone data.
if i use wifi hotspot on -> wireless extender, it drains my battery too fast. And if i connect it to the charger, the device gets hot. This will be my last resource but i guess it will damage my battery if i will do that everyday and every hour
any inputs? i believed asus got one but i don't know the exact model. I'm googling it but i got no luck
thanks
i am using Samsung Galaxy S4
It's generally not a great idea to drain the battery at the same time that it's charging, it creates a great deal of heat and in turn will hamper your charging efforts and affect the long term life of the battery. Using a mobile hotspot does drain a lot of battery because it's using a lot of services at once, there really isn't anything you can do about this.

Phone radio is killing my battery on a S6 & Wifi signal is very poor - please help?
Hi folks,
I'm new to these forums and having read through more posts than I remember I think I need some help - apologies in advance for the length of this post!
I bought a S6 approx 4 weeks ago, having had the S4 which served me well. I immediately noticed two issues
1/. Battery drain
2/. Poor Wifi signal
1/. My battery drain is currently unacceptable, I charge to 100% and unplug overnight so screen is off - I wake up 7hours or so later to find it has drained overnight to 75% or even less. I have power save mode on ALL the time, I have disabled all the non essential and probably some essential apps such google player etc. I have location, NFC, Bluetooth, Sync, Always allow wifi scanning, none of my apps are set to sync automatically etc switched off (having read all this good info on these forums). I installed GSAM and never saw any major issues although the screen would be showing close to 40% (I have black background and only on Amoled Photo display rather than the Adaptive display which is so much better!) I then read on a post today the GSAM Wifi profile had to be edited to 767 to show an accurate usage - I did that this morning and lo and behold I have a Phone Radio zapping 43% battery. Can someone please tell me how to switch that damn thing off or how it can be managed? I notice the battery issue is alot worse on wifi than using mobile data. I have attempted a cache reset post 5.1.1 update. Any other ideas on saving battery life would be very much appreciated.
2/. Wifi signal - I have a Virgin Media Superhub router on a 50meg connection. My S4 had no issues throughout the house picking up a very good signal and wifi speed was excellent. All other devices such as laptop and IPAD have no issues getting a good signal on both 2.4G and 5G On my S6 unless im in the same room as the router it is extremely poor and I'm guessing has also something to do with my battery draining so the two may go hand in hand? Again having read many posts on these forums I have changed my wifi settings DNS 1 & 2 to 8.8.4.4 - I haven't seen this make much of a difference though. I used the DNS SET app I read somewhere would also help but unfortunately the poor signal and slow speed continued.My battery drain is worse with Wifi so I try to use my data plan but im using that up very quickly and would love to use wifi! Does anyone know anything else I can have a go at?
I am loathed to try the factory reset option if there are other things I can attempt first to save me setting up the phone and my go launcher app etc. I have attempted to attach some GSAM screen shots but cant find an attach link anywhere?? can someone advise how to do this? more than happy to provide any other info. Any help would be very much appreciated - thanks in advance.
I have the low wifi signal problem too. My friend has an S6 and has also poor wifi signal at the same spot. Others phones like z3 compact or moto g2 have more signal than s6 at the same spot.
It's annoying.
Hi!
My Huawei P20 is draining very fast when connected to my wireless network. I get like 20-30% drain overnight, which is huge. When using mobile data I lose like 4-5% (when I first got the phone I was having this percents on wifi also, after some time the drain started to happen) which I think it's pretty good.
Has anyone else encountered this issue?
Same problem here. I am on firmware 9.1. 0.325

I still didn't find a fix for this. There are some times when the phone works well, and others when the battery drain fast. If the phone runs out of battery and closes, when I charge it, the next couple of days it drains fast on wifi, after this it works well again.
It is a software problem for sure, but don't know what is causing this. My firmware is 9.1.0.371
I think the optimiser switches off WiFi and there is a reason for that
