Hi,
When i connect to the wireless network on my university my battery drains faster than it does on home networks. The mmc1_detect wakelock drains more battery when on this network. In the android battery stats i.can see the android system going up after i've connected. I had the same problem at my.previous school which had the same system(you have to log in with your school account to gain acces to the internet)
Does anybody know if this can be solved? The difference between my battery at home and my battery at the university is pretty big now. (5hrs screen on vs 3hrs screen on)

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
Cell standby 50%
Phone idle 42%
Display 5%
Android OS 3%
Android system 2%
Is this normal?

A high cell standby percentage means you are in an area with little signal. If I spend all day playing Skyrim in my basement (like 14 hours) then I also will have an astronomically high percentage of cell standby. Basically, your phone is trying to connect to the network when there is an unreliable signal.
My suggestion: Turn airplane mode on when you plan on not using your phone. If this is while you sleep, you can configure the app Tasker to put your phone in airplane mode and reconnect every hour or so to collect text messages. The guide for this is here.
Word thanks (;

When xt860/xt862 first came out cell standby was at the top of everyones battery usage list. Recent updatez have fixed that but ive noticed some roms still have it as being top of the list, however to me it hasn't seemed to affect my battery life. What phone model/rom are you running

Liberty also has an issue with displaying cell standby usage. I'm running Liberty 2.0, and I constantly get cell standby of 40+ percent, no mattery how much I use or where my phone is. If your battery life is fine, then dont worry about it. My extended battery can last up to 3 days..

I got 40% cell standby today while connected to wifi all day. I wasn't more than 50 feet from router all day and it was still high.
Not sure the signal strength is the sole (or main) factor.

Cell standby is not just for the 3G data connection - it's also for your connection to the voice network, which is not switched off when you are connected to WiFi. So, if you are in an area with a weak signal, unless you go into airplane mode and then turn on WiFi, you could see high cell standby.

Yeah im literally next to my router with wifi on and cell standby= 47% but battery life isnt terrible for me. Ive been at moderate-medium usage today and its been 10 hours im at 57%

I wonder if it's an issue in the reporting
Hi guys.
I know there are million of threads very similar about battery drains, but I can't find a definitive answer.
On wifi I think our x8 works with no particular drains. But on 3g is very bad.
Only data, whatsapp and mail (every 3 hours update) on. Well, 1 hours of web browsing has been my maximum(always thalking about 3g). Is this normal, according to you?
I'm now testing Gingerdx x30, but I tried other roms with more or less the same results.
What about you?

3g should drain battery more then wifi. So its normal.

Even if I have 3g on in standby mode , battery drains too much imho.
3g Reduce the battery ..due to receiving large amounts of data transferring great performance, decibel
Hz, everything thin reduce it

Ok, I Understand.
What's your usage with 3g?
The 3G mode power consumption depends on the signal quality and the distance from the connected rx/tx station. With 2G mode too (this is normal), but the 3G range is much smaller than the 2G range (approx. half distance than the 2G). So, the power consumption increasing quickly with the distance. With weak signal the radio device working on max power, and the battery draining due the higher frequency (1800/2100MHz instead of 900MHz of 2G) Example: if my 3G signal is weak, my battery is burn like the hell (in standby too), if I go to the nearest rx/tx station (max. 3G signal), the battery burn faster than 2G, but the difference not significant. You can play with some RIL settings in build.prop, but you can't win extreme battery savings with these settings.

That is normal.
However, if you're a light internet user, I would definitely recommend you switch to 2G only. All the web pages and mails would take a bit longer to load, but you would do a lot to save your battery. You can do it from the settings screen if your ROM supports it, but if it doesn't, the code *#*#4636#*#* can get you there.
Well I'm testing 2x battery
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 do have what's app and Instagram apart from the other two that you mentioned .. my general use is of 3.5 to 4 hours per day but by the end of day the battery dies..so my question is should I stop background running apps? I have around 30 to 35 apps installed on phone..
I got this tips for battery longevity..
Also, don't put phone on vibration mode...it consumes battery...either silent or sound..
Attached
1) get charger alarm and set it to 80%
2) disable uselesa background apps.
Thats it.
I charge to 80% every morning, despite having 4G volte + data 24/7 with upto 2 hours calling, 30mins-60mins gaming, 1hr+ chatting, 30mins+ 9gag, 30mins youtube...
Mine phone still stays around 35%...when I check next morning
Data (4g), location, auto synch are ALWAYS turned ON
(Yesterday my totol usge was 5.5hours with 1hour gaming (fortnite)... My battery was at 25% when i checked this morning)
I recently bought the honor play but have found the battery usage to be higher than I would like at night during standby. I leave my phone connected to wifi and 4g (although 4g is not on when wifi is) and I noticed that the phone wakes up a lot during the night. It seems that it mostly wakes up more often when on wifi as when on 4g during the day there are far fewer wake up events. So to solve this problem I'm using tasker to disable wifi, deny all network activity (excluding calls), bluetooth and auto sync for me during 11:30pm and 7.30am. The result is that the phone barely wakes up at night now and I am getting 2-3% battery drain over 8 hours instead of 10-14%. So I would recommend doing this, as it seems to improve battery life. There may be other apps that can do the same thing but I like the interface and usability of it over something like automate.
Edit: I would also recommend leaving the standard power saving mode on all the time as it doesn't limit performance but just limits background activity. However, this does disable auto sync, but then you could just set auto sync to turn on at set intervals using tasker, at least that's what I'm doing.
