Battery life with low reception - HTC EVO 3D

I am amazed by the battery management of the phone. Where i work is practically a bunker, almost no signal at all. The phone keeps jumping from sprint to roaming all day. And i still manage to get out of work with 30% battery left. My epic was always on the charger.

Mine's been good at my office too (virtually no Sprint signal), I'm really happy with the battery life so far. I have missed some calls due to jumping between Sprint and Verizon, but I expected that to happen.

anything you guys did with settings or something, because that is NOT the case with me. In the back office where I work I get low signal and goes to roaming, phone barely lasts the time that im there.
Havent been at work the past two days and the battery life is great, went over 24 hrs without a charge with light usage. Dont really use it that much at work other than a few calls and txts and some very light web browsing in the areas I get data connection, not enough to kill the batter like it does I would think.

If you don't use Facebook or any of the other carrier bloatware, uninstall it via the settings > applications menu. I was surprised how much I could remove without having root, it's really nice to see.
I managed 50 hours off of a single battery change over the past two days, battery saver mode (set to 15% threshold) finally kicked in this morning, but I have great signal strength at home and work.

IMO the battery life is much better at stock on the 3D compared to the 4G, but it still isnt great. Im sure once we get custom kernels and ROMs that things will get better.

Hell No, I charge my phone for 3 hours and i barely use the phone and it dies half way throu the day. I dont even have my Wifi, 3G,4G, Bluetooth On, Even Brightness i put it to low lighting and the phone doesnt last till 6pm. I charge it in the morning (11am 100% charge - 5pm 2% left. I love this phone but the battery life sucks !!
Well idk what's wrong with ur phone but I'm getting amazing battery life, but i get it today so idk but has been using the phone like crazy with non stop!!

Battery life is awesome! My 4g has 3500mah and my 3d has 1700mah. I use both and the 3d last longer every time! In fact, I have 3d on wifi all day and making phone calls with "groove ip" and it still lasts longer!
Great mine has been in 3g, WiFi,Facebook, XDA app since my las charge (6 hours ago) texting a lot too I'm it still on 65% pretty damm good

hmmm.. Its shocking to me cause my phone dies quick. Well i have insurance so i think i will just get it replaced or buy another battery. I had other android phones that lasts me almost 2 days, but so far i had a bad battery experience with this one.
Yea something is wrong with that battery, buy a new battery and test it

On my first day I can seriously say the battery life on the 3D exceeds that of the EVO 4G .
Battery : 24%
Been running for the past 9hrs 53 mins
This is with atleast two hours of phone calls
I just spent an hour or so soaking up 3D youtube videos
Well over 150 texts sent and received today .
I spent a good part of the day playing with settings , checking facebook .
Weather (every hour) and Google(mail contacts calender) on sync
Playing around on the market .
changing notification sounds and ringtones .
My previous EVO 4G would have died long before now . If you are expierencing bad battery life . Check for any apps that might be running or causing your phone to have issues . Remember not all apps are set up for gingerbread just yet either even though most are . Use old tricks from the EVO 4G to conserve battery life . I leave 3G and gps on all the time . But if what they say is true about batteries breaking in especially after a few charges and discharges I am gonna be content with this phone as it is . I can only imagine what will be the next leap forward when devs start making kernels and roms for this thing . Seidio's extended batteries market might collapse LOL .
I don't see how any of this is possible. The EVO 3D dies when you make a phone call, just like the 4G did.
I"m going to have to buy an extended battery so I can make 2 phone calls. This blows. How are you all doing this?

Something isnt right there if you make two phone calls and the phone dies , my advice is take it back to sprint and explain your situation . Either your phone is faulty or the battery is faulty . Also did you accept the updates ? Supposedly the updates include some fixes to correct a sleeping issue the phone was encountering .
did everyone remember to run that battery COMPLETELY dead and charge it COMPLETELY up at least 2 times?
I did and no problemo!

Nope, because its not necessary to do that with Li-Ion's. Its also unhealthy to discharge a Li-Ion battery too far (although I'm going to assume this phone has a discharging characteristic that would prevent 'complete' discharge as that would completely kill the battery).
Regardless, my battery life is amazing compared to either of my 4G's (1 rooted, 1 stock gb, and even my buddy's 4G with extended battery). My absolute heaviest usage day, off the charger for about 10hrs and I still had in the upper 60's left of my battery percentage. I leave 3G, wifi, & gps on all the time. I also generally have on my BT and am connected to my headset.
I still wont forget the time a HTC Rep called me asking me my opinion of the Evo 4G . I told her I loved the phone . She asked me if there was anything that could be improved on . My response was this "Dear god put a real battery in these things , I know flip phones with bigger batteries " . She was alittle speechless at that one ROFL but apparently they listened some what LOL
Heavy usage to me is when the screen never sleeps. Like you are watching netflix nonstop or using the web nonstop, or Sprint tv nonstop. In situations like this all the battery saving tips will not make much of a difference since the screen on and 3g/4g radio will be on constantly. If any 3d can get 6+ hours of battery life out of it I'll buy one right away. Sadly most of the usage posted here is what I consider light or medium usage at best. Mucho texting and weather widgets is not what I consider heavy usage.
45% left after 21hrs. wifi on constantly, been texting, playing games, playing with 3d camera. Although it was sleeping during the night, but still pretty damn good.

I was being very sarcastic. it's not that bad, but my battery barely lasts 4 hours. I make about 300 outbound calls a day to clients, that doesn't include the incoming email, calls, txts etc.. syncing, GPS, sigh....
dont worry am on the same boat, i barely used the phone much and i get the same problem with the battery life. I completely charge it with everything off, wifi, 3g, 4g, bl/tooth, no syncing and it dies half of the day. I think some 1st batched phones in the U.S are faulty
Which charger are u guys using? I use the two in one Sprint wall charger thats also a cigarette car charger. My battery life is not great but its not horrible. I get about 6-8 hours with heavy use

Poor battery life?

Anyone else getting poor battery life with their Razr? I cannot go a full day without recharging at some point. I need a phone to last at least 16 waking hours, so I can recharge at night.
My typical usage pattern is a few hours a day of web browsing and email. I don't game, and I rarely stream video or do anything data intensive. GPS is switched off unless needed, and my screen brightness is set to auto.

I'm actually getting pretty good battery life compared to what I've read so far... Though it wasn't 16 hours, I DID get almost 12 out of it yesterday with pretty heavy usage all day.
I highly suggest using the task managers auto end feature. It'll turn off any apps you set it to after 2 minutes. Fast Reboot is also a very good friend of mine. Though I haven't set any yet, I've played with Smart Actions, and I think with some tinkering, it'll work wonders as well!

JuiceDefender with root, AOSP helper, and a manual setup is extremely helpful. The data disable override feature should be on as well.
Make sure in-pocket detection is OFF, as well. It kills the battery really really quickly.
As far as smart actions.... Just turn on the premade battery extender and nighttime battery extender. And data off on screen off.
Lastly, screen filter from the market helps a lot.
I got a full day and 2 hours of use today on Wi-Fi. I'm sure on 3G I could get 20ish hours, and on 4G I could get 15ish.
Mine is great. I got my phone yesterday so it isn't fully calibrated yet but it still last very good.
I've found that the the biggest drainer for me is being in an area where 4g/3g is flip flopping alot. Other than that, phones got amazing battery life. Especially on wifi.

What has always worked for me is to use an app called brightness profiles. My phone lives at 30% brightness 95% of the time. The RAZR has a super bright screen, 30 is plenty.

my gf just got her razr a week ago and says with regular usage she gets about 4 hours of battery life. thinking about returning it for a different phone or maybe she got a dud? she doesn't want it rooted so I did everything else mentioned. if there are more tips I'd love to hear them before the phone goes away for good.
Turn all haptic(vibration) feedback off. i get about 20 hours on 4g, all apps in auto end list, i don't have any BS apps that like to run randomly, not synced with my fb,twitter, g+(have my laptop all day so no point), brightness is about 30%, smart actions usually kill my batt faster for some reason, gps is on, timeout is 30 seconds. I text a lot, and about 2hours of phone calls perday

So I took everyones consideration and yes I got better battery life but I don't do much on the phone. My gf does a ton of more stuff than I do and by the end of the day. She still has better battery life when for me I did a few txt. Check fb on my lunch break and I'm down to 20% by days end. Whereas my gf surfs,txt,stream,chat half the day and she's down to 60%. Only difference between mine and hers. Mine is rooted. Mind you she has her 4g data on while all day I'm running only 3g. Any more help would be appreciated

Put the power control widget on your home screen.
Set brightness to minimum or lowest setting that you can use well.
Use wifi whenever possible. Turn. Off new network notifications.
Turn off animations.
Use a simple, mostly black wallpaper.
Turn off auto data sync.
Since I'm around wifi all day I can easily go 12 hours without a charge and have plenty of battery left. 4g is a total power hog.
If you're outside you might want to buy the power pack... good luck!
I think typical android battery life for a normal use will be varies from 6~20 hrs depending on the way u use and what you use.
when running only data/wifi when i need it(off data/wifi when not using), i can get more then 20hrs. if i on data all the time, i can get 8~10hrs with with some facebook, emails and lite web sufing. i will get 4~6 hrs on heavy use on gaming, video and music.
but u need smart action, task killer and ti backup to really optimize the battery life.

yeah.
battery life is a hard problem for android device for a long time.
but i can use some trips, for example.
1. using the task managers, it can kill some app that you used.
2. using the app called province electricity king or the same function app.
3. turn off the back-data auto sync

How strong is your signal at work? If you have a weak signal, the phone turns up the power to the radios and will drain your battery trying to keep that weak signal connected.
That's pretty atrocious.... Can you switch? What mods do you have?

Did you charge it from a computer? Maybe the cpu isn't entering the deep sleep mode.
It's your cell signal. I had terrible reception with my Verizon Nexus and since switching I am shocked at how much better my battery life is. I don't use the device more or less, but this is amazing.

What are you guys using to display battery percentage on the toolbar? I'd like an app that can do that, but the best I found was battery notifier. I'm not rooted, on stock ROM.
And, to the original poster, I normally get anywhere from 15-28 hours on battery, depending on how many emails, texts, games, photos, etc I do. I have managed to kill it in about 4 hours, but that was on a marathon plants vs zombies session.

Try Battery Indicator. Puts a permanent notification in the status bar but that's the best you are going to get w/o rooting. That app is fairly small and the numbers are easy to read - others I've tried are much bigger and are hard to read.
Turn off your Wifi if you've been leaving it on. Also install CPU Spy and see if the phone is entering Deep Sleep - or not.

Better battery life?

i remembered there was a flashable zip to make the battery life better, but I can't seem to find it.
anyways what i've done so far is put the brightness to low, turn off gps , put the animations to .5 , sync emails every 2 hours , only have one widget running , installed the latest faux kernel .
It helped a bit , but nothing too noticeable. Any more things i can do to make it better? any tweaks or anything?
which rom are you usingg?? turn off auto sync, disable check for update.. also your battery can wear out over time, can purchase new battery... most people recommend anker battery,

It did not seem to work with my HD2, and I did not use it originally with my Ruby. But now it seems to work fine. I mostly use it to turn off the mobile modem (seems to be my biggest battery drain) except when the screen is off and once per hour to sync my various programs. Using this configuration I can last all day, even with my cheaper replacement batteries.
But nothing is going to make the device go if one is keeping the screen on (like gaming). 3-4 hours max in that setting, and I still carry two spare batteries for those times my son gets his hands on the device.

I don't know what you are talking about but I get crazy good battery life... Here are my stats from 2 days ago I took a screen shot of... And I don't use juice defender and I am using teamvipers sense 4.1 rom and i have around 180 user apps installed on my phone. I just don't use data but my wifi is on all the time (don't have a data plan) and I play temple run and empire defense a lot hence high screen on time. Major thing about the rom I'm using is that it's very efficient when idle. I also keep my capacitative button lights off permanently as I think that also helps my battery life. Only downside is that I don't have working bluetooth in this rom

Well, yours is unique. Most people have pretty poor battery life. I've had 3 Amazes and all of them really drained the battery when the screen was on. However, as I said, my GSM modem is what really drains the device as well. If you live near a cell tower or in a downtown area with good T-Mobile, the modem won't "hunt" and will deliver better life.
Also, the stock battery is the best, in my experience.

2g doesn't really drain too much battery, but it's still always a good idea to turn data off when you don't need it. The rest depends on the rom you are using but again there is no set number... From what I have read I am an odd ball with the battery life (and am not complaining). I assume you live in karachi? It's not even worth it to pay for 2g...I read somewhere that 3g will finally be rolling out to mobile networks in Pakistan in 2013...but we'll see...

1. Turn down screen brightness, screen kills the battery on the amaze more than anything else
2. Turn off automatic sync, this is very helpful
3. If you're on a JB ROM then turn off google now, this will stretch your battery life significantly.

Comparative battery analysis thread (GSam Battery Monitor only!)

Taking a close look at the long battery review thread, while there is a lot of information there regarding individual battery usage, the screen-on and overall usage times vary by a lot. It is impossible to draw conclusions regarding why the results vary so much, because most people did not give enough relevant information there.
I think it will be very interesting if we all used the same *comprehensive* method to compare our battery usage. We could really discover important things about our individual usage and how it compares to others (and how to make it even better).
It is important to note that when battery life is low (in comparison to other G2 users), sometimes this could be because we are taxing our device with heavy usage (and nothing is actually wrong), but other times something is definitely wrong (wakelocks, bad phone reception, etc.). This thread will help each and every one of us (that get lower than expected battery life) understand which of these two possibilities is correct for him (something wrong VS taxing usage).
In order to do this, let's use the excellent "GSam Battery Monitor" app, which could be downloaded freely from the Play Store.
Please post your results when your battery becomes low (around 10 percent), after it was fully charged.
If you want an accurate opinion about your battery behavior, with tips on how to improve things, please provide all the attached screens (please provide the graph image in landscape mode, and sort it by "other"):
Is this really necessary? The G2 has a fat battery. But any amount of power can be drained if you drain it. Enough said.

I say let's give this a shot. This phone has a beefy battery indeed, but still, some of us are posting 7 hours screen-on times, while some of us only 4. Let's see what this thread will provide us with. I have a good hunch this will be a very revealing thread.

Okay Well in the interest of troubleshooting good luck. I get 1.5 days easily with a good amount of music play. I always suggest people delete the Facebook app and use it in the browser, and disable data/sync while you're in a bad reception building/area

Yep, these are some solid good general advices.
I could only drain the battery to 50% today, so I'm posting this for now to get this thread running (and tomorrow I'll post the 10% results). It's funny because I have no trouble finishing the battery everyday, yet today it's giving me "problems". It's like it knows it is being monitored, and the battery hogs are afraid of being greenified...
Let's get over my results in the main screen:
Phone: yes, I did not use the phone to make phone calls. Not unusual for me...
Screen: almost 4 hours screen time, pretty impressive considering the phone has been running for more than 13 hours, and the battery is at 50%. On the other hand I did not make any phone calls, so this could be part of the reason for that excellent screen-on time. Btw, I'm using "Lux brightness control" instead of the LG2's pathetic brightness control feature, the Lux app itself drew practically zero power (as can be seen at the "App Sucker" screen, or actually, you can't even see it because it's too down in the list).
Phone Radio: At 7.9%, I don't really know whether it's good or bad, although this is definitely not a major battery user. I've attached the cellular reception screen too, just so people could reference with theirs. I think overall the reception is pretty good according to that image.
Wifi Active: The Wifi has been on the entire operating time. Most of the time it was connected to my home router, and some of the time it was not connected at all, but still on (when I was out of the house). I'm attaching the Wifi screen so people could see how much traffic the phone had through wifi, for reference. With only 3.9% battery usage, I think there is no need to turn the wifi off, ever.
Held Awake: The phone was awake for 1 hour (while the screen off, that is). Out of 13 hours being awake for 1 hour, I'm not sure whether this is good or bad. This will become clearer when more people will post their result here. It says that the power that was drawn during this 1 wake hour is 0.0%, I'm not sure if this is true, or some kind of inability of GSam to calculate battery usage for this awake period (if GSam IS correct, then I guess I don't understand what's the point of deep sleep, if the phone draws practically zero power even when awake...).
Bluetooth: The BT was on the entire operating time, but connected to a device only a short amount of time. In any case it drew no power according to this screen... like wifi, I think there is no need to turn the BT off, ever.
Regarding the "App Sucker" screen, I can't really say anything intelligent about this, no app seem to drain the battery too much. The 4 hours screen-on time was mainly spent browsing the internet, using Whatsapp, watching youtube, using XDA app (not even listed in the first screen) neither of which seem to drain the battery too much...
So, now that we have some reference (and a reference for a pretty good battery behavior, I think) It will be interesting to see how your results compare...
Just a quick question. I work in a building where there is terrible service. I mean so bad sometimes I get none at all. How does turning off mobile data save battery. Essentially your phone is still trying to connect to the mobile network all the same. I'm kind of looking for a technical explanation not just the 4g uses more battery type.

Don't forget, the vzw version will throw a wrench into these comparisons.
Thanks Devs. From my VZW G2.

If you have bad cellular reception, turning off mobile data can help, but as you said it won't completely solve the problem because the phone still needs to connect to the network so you could talk and send SMS. I think switching to airplane mode (and using WIFI) is the best solution for battery life in this case. Still, I think you should use GSam to really see how much battery is drained by your bad cellular reception.
I am using it now. Waiting until it drops to around 20% to post my results. Will get back.
Edit:
Here are my statistics. You think my phone just has bad reception and is in a bad area or there is something wrong with my antenna? My old Droid Razr HD was the same way, barely any service. I'm definitely not staying with Verizon. I pay out the noodle for "the best service" and I get crap. I live on Long Island outside New York City, my service should be amazing.

Ok, as promised, here are my 10% results:
Phone: did have some phone calls today, though nothing significant. I guess my usage can't really tell how significant phone calls are going to be with the G2, though this should not be a significant battery drainer for most.
Screen: As you remember, yesterday, after 13 hour phone usage, I had 50% battery, I had 3 hours 47 minutes of screen-on time. At that point I thought I might get over 7 hours screen-on time, but here I show about 5 hours 25 minutes. I guess that if I completely drained it, I would have gotten close to 6 hours, not bad.
Phone radio: seems similar to yesterday, about 10% of the battery... I still get good reception, as the image shows.
Wifi active: Wifi had been on the entire time, using 5.6% of the battery.
Held awake: So, yesterday after 13 hours of usage, the screen was held awake 1 hours. Today, after a total of 31 hours, the phone was held awake a total of 3 hours. It seems that the phone consistently is held awake for about 1 hour, every 10 hours of operation time (under my specific configuration, that is). I still find it weird that this "held awake" time did not tax the battery at all. How is this possible ?
Bluetooth: was on the entire time, not connected most of the time. Zero impact on battery.
Regarding the App Sucker screen, similar to yesterday, can't say anything special about this. This day I kept browsing the interned using Opera browser, and added another hour using Runkeeper with GPS tracking (with screen off). After a full cycle of battery usage, the main battery draw comes from the Home launcher, next is Opera browser, and then the apps become pretty much insignificant in terms of battery usage. Maybe two last points here: I'm using both Lux brightness control (to control auto brightness) and Delayed Lock (to remove the lock when connected to certain wifi points and BT devices), both of these apps always run in the background, yet consume practically zero battery, so high recommendation for both of these (they also work great with the G2). Last point, I'm using all the google location access services (everything is turned on there), and I really don't see this taxing in any way, using this GSam report.
That's it for now. Waiting for your results for comparison.

Interesting results. I thought this thread would be revealing, and it doesn't disappoint already.
Your phone reception is pretty bad, much much worse than mine. BUT, you can see that the difference in battery draw is not really significant between my case (I have great reception) and yours, in both cases the phone radio took about 10% of the battery. It seems that the phone reception qaulity doesn't make much difference on the battery (whether it's pretty good, or pretty bad. Maybe this will change if the reception is horrific... like 0 and 1). Comparing my GSam report to yours, you will gain practically no battery advantage by making your phone reception better (at least considering your current phone usage - you barely made phone calls, but still phone reception is also important in order to keep the phone connected to the network, and also for mobile data...). This is REALLY surprising, I thought that when comparing my excellent reception to your very bad one, if I got 10% battery usage (for phone radio), you'll get something like 30%. This did not happen at all, surprisingly!.
Your Held awake time is pretty much similar to mine, as evertything else is similar to mine (wifi active, etc.), yet you seem to get significantly less screen-on time than I. I can think of one explantion: I see you are using G2's automatic brightness control, which is pretty horrible, while I use Lux brightness control, which can reduce the brightness much much more, when it's appropriate. I really can't think of any other major contributor to your battery drainage in comparison to mine...
One thing still keeps me bewildered: why doesn't the "held awake" period tax the battery ?? I mean, the phone is awake, yet no battery is being used... how could this be possible ? Is this a problem of GSam which can't read this information right ?

When you turn off mobile data the phone stops searching for a data connection, thus this battery draining process is halted

Barely read through the details but I charged my phone to 100% last night, pulled it around 6am today. Been texting and tweeting moderately. Made a few phone calls, checked voicemail. Used the flashlight a couple times and took a few pictures, flash off.

This is true but look at the sent part of data of the phone radio. My received data is much higher then yours but I can assure you I only receive data via WiFi because my phone signal is so bad. Your sent in comparison much more data then me probably via your phone signal.
This is also very important. I had my mobile data OFF while at work today. I have a shift tomorrow where I will keep the mobile data on and post new results.
Edit: Also about the phone being kept awake and not using any battery. It does seem odd. Perhaps we should also use the orginal screenshots of the stock battery app (pending you still have stock rom).

But, I don't see how the stock battery app will shed any new light on the kept awake period, if anything, the stock battery app is less detailed regarding almost everything...
