HTC Incredible :: WiFi And Battery Consumption
Sep 26, 2010
As an experiment I set all my internet apps - backup assistant, gmail, people, calendar, news, weather, amazon, stocks, facebook, etc, etc, ETC, to not automatically update, sync, refresh or do anything on the internet without my say-so. I then turned off my phone, put a full charge on it and turned it back on again to reset the timer for Settings > About phone > Battery > Battery use. For the next 6 hours I made a few phone calls while I was not in range of any wifi; I used a few local (non-internet) apps like calculator and stopwatch and camera but I did NOT use any internet apps. At the end of that time "battery use" showed Wi-Fi at 30%, Cell standby at 28% and voice calls at 6%. So why is WiFi so high? Is that just from some "keep alive" or beacon or polling feature? Or is there some app or process I don't know about using the WiFi connection, and how do I tell?

First, these screen shots were taken after the battery had been fully charged 2 hours prior. I pulled it off right after the light turned green, so that isn't the issue. Also, I've already done the charge, turn off, charge, turn on, etc. thing. My light turned green almost instantly the first time I turned it off and plugged it back in. The screen was on 18.5% of the time during this stretch, so that's pretty heavy usage. But why would the system have been running 53.3% of the time? I wouldn't think that number would/should be much higher than the screen-on time.

I was trying to search and use google with no luck (from my Hero) so I am sorry if this is a old question. I am currently using a HTC Hero (Sprint) and am purchasing a HTC Evo next week and I was wondering if the battery consumption is similar or a lot worse / better etc. with my Hero I have like gps, wifi, bluetooth off and all the other tricks? I don't mind having all that disabled it never bother me as I really never use twitter, facebook and the gmail app works just fine for me. With my Hero I can get through the day always with all that disabled so any insight if the Evo is similar would be appreciated! Oh and I am not a former blackberry user that expects my phone to last six days on a charge.

I went on vacation last week and did a comparison between my X and my wife's Incredible. We were on a cruise, so both phones stayed in airplane mode due to not needing a signal. With absolutely no use, not even turning on the screen, my battery went from 100% - 10% in 37 hours... Dumbfounded, I went to running app.s and stopped nearly everything. I tried again and only got 49 hours. In comparison, her Droid used 10% of her battery in 9 days! The X advertises 220 hours of standby....I am only 180 hours shy of this, something wrong or do they just lie? Remember, my numbers are no use at all, the battery manager only showed "phone idol" as battery consumption.

My question is basically "can anyone recommend an application that will tell me which applications are draining my battery". I've read about task killers and usage and turning stuff on and off, I'm not worried about that, and I don't need to know why (i.e Google Earth uses X units per hour.

Basically i went from getting 15+ hours of battery life to getting 4 hours today and maybe 7 yesterday. This is 2 days in a row. Running baked snack 1.9 with not too many apps.. I had gone a few weeks being amazed by battery life. I don't think I've added any apps that would cause this.

My system was starting to get a little bit laggy (especially messages app), so I deleted all of my messages and a load of apps I no longer use. As well as my phone speeding up by leaps and bounds, my battery is getting about 3 hours additional life (minimum). Before, 15 minutes after taking my phone off charge it had lost a bar, but now.. I took my phone off charge at 7:15am and listened to music for 40 minutes on the way to work.. it's now 10:19am and I still haven't lost a bar!

its only been a few hours so I will let you know more later but after the update my battery life was no where near as good as it was the 1st 4 days I have had the phone. I toggled the battery profile from "smart" to "performance" and than back to "smart" and it seems to be holding steady at the current battery level. I will know more as time goes on

I had made changes in S/W as suggested in post : [URL] .....
The device I am working is also having wake up lag about 2 sec.It varies from 1.2sec,0.8sec,1.8sec..etc. I implemented the new wake log to prevent the phone from deep sleep as you have mentioned. Now the time required for wake up from deep sleep is reduced to 0.8s and its quite consistent. Although I have to yet check for battery consumption during deep sleep.
However I have found that now when the phone is reset the battery consumption is more during the power up of the phone. For Ex. from 36% before power up and 24% after powerup.
Checked with another device and its only taking 3% for boot up.

I have been monitoring my battery consumption for a while now and noticed that on minimum brightness, with screen timeout set on 15 secs, always 50% to 80% of my battery is being used by the screen! I was wondering if anyone else is getting a similar battery consumption?

The only thing putting me off rooting my Hero and installing the villain 5.3 ROM is concern about whether it will shorten the amount of time I can go between battery charges. Does anyone have any numbers on this, or even just impressions about whether consumption is better or worse than on the standard 1.6 ROM.

Has anyone else noticed the battery charge does not seem to last well? I have the wifi turned off and only enable it when required but just general usage seems to sap the power quite quickly. At the moment I'm not sure a full charge would even last a day! Are there any smart apps out there to help manage this? Do widgets relly use that much power? The Android OS itself seems to use an alarming amount of power as does everything else!

I have a Motorola Droid with VZn. At home I can start up WiFi and connect to my home network. What I am wondering is if it is better to leave it connected with 3G or to connect the home network as it relates to battery consumption. Which one is easier on the battery?

I've been trying some music players and went through the threads we have here on the subject. I'm trying to figure out if some players will drain the battery faster than others. I've tried the TW Player, Winamp, MusicMod. I like MusicMod the best (I believe its a modification of the Froyo AOSP player) but it seems to drain the battery pretty fast. I've been using it for about 4 hours and went from 100% to 38%. What are your experiences with battery drain and music players?

My non-branded GSM hero eats battery. So I decided to check some things out. These numbers are starting from 100% battery, and after a reboot - the only thing I open is settings to check the battery level, and then I lock it and leave it for 6 hours. In all cases the final awake time is low, less than 15% (because I'm doing nothing with it). Full data-sync mode - gmail sync, twitter, etc - about 10% battery use per hour. Retro mode - GSM only, data switched off - 6 % per hour. Airplane mode - 3.5% per hour - WTF?? (Awake time ~1%) Why is battery consumed when it's doing sod all?

I really like to run Dolphin in the background and it runs fine (on Fresh 1.1 with Gumbo Kernel + setcpu) and I have 2-3 tabs open and everything else runs fine. I try not to run too much else (if I do ebuddy it gets slow, so I usually don't), but I was wondering how bad this was to do, and if I could check somehow how bad it was. I don't know a way to tell how draining this is on the battery or how the phone runs, is there any way to check?

Just want to see how many use live wallpaper, and if so how long does your battery last using live wallpapers. And also heard that if you use live wallpapers etc for awhile it burns the image on the screen.

Just wondering How the FM Radio in desire works. Is it like in other phones where you have to use the headset for the radio to work? And another question to those that might have tried, how long would the battery last when using FM radio?

This sunday (10/10/10) my X10 mini said an update was ready and I went forward at updated my phone (Firmware = 1.6, Core = 2.6.29, Version = 1.2.A.1.174). After this update the battery consumption is more than horrific. Even at standby the phone doesn't last more than 24 hours, this was NOT the case prior to the update. The phone itself and its functions works fine.

Recently bought a Polaroid PMID701C tablet. I was looking for that battery consumption graph that is on most android phones/tablets. The one where it shows which apps and hardware are consuming the most power. i couldn't find it and gave up. until one day when a low battery warning appeared on the screen. usually i cancel it, but this one time i clicked OK and it brought me to the battery consumption graph i was looking for.
seems to be the only way i can access it. i understand that this tablet is entry level, but shouldn't i be able to get to this without having to wait for a low battery warning?

I am using the Y5 app and my phone connects to my router when I am home. I just checked the battery usage and Wifi was showing 22%. My up time is right around 27 hours. Does 22% sound a little high or is that good?

I was just wondering how much battery is used during wifi/3g and which one is more advantageous to use? which one uses less strain on the battery? I live on a university's campus so i have widespread wifi all the time and it is most of the time faster than my 3g network... is it better for me to just use wifi all the time?

This just popped up my on my twitter. Y5 Battery Saver Keeps Wi-Fi On Only Near Trusted Spot. When you connect to wifi, it'll remember the rough location (without GPS). Periodically it'll tap back into that location and if you are near it it'll flip on WiFi so you can connect. If you aren't near an area you've connected too before, it'll keep wifi off.

I started using WiFi exclusively at home and my office after reading about the benefits on here. I noticed a tremendous increase in battery life. But when I'm on WiFi at my gf's parents house, the battery drain isn't even about the same as 3G it seems like it is much worse. What could be causing this? The signal strength is often better at this location than home/office so that shouldn't be the problem.
