Help Battery life and battery management

Quality of the phone signal has a LOT to do with the overall battery life. My office at work is in the basement level of a hotel, and the phone is constantly roaming. I'm lucky to get 10 hours of life, and my "time without signal" is usually somewhere in the 90% range.

That being said, when I have a day off, and have normal signal reception, my battery life is phenomenal. I can easily get 20+ hours with moderate use.

I have stock Sense, Juice Defender Ultimate controlling my WiFi and 3G, Bluetooth, GPS, and 4G off (unless in a car and driving (for BT/GPS)), and I usually have the brightness set to around 10%. All my accounts are set to update once a day, and I have the Mobile Network automatically turn off whenever WiFi is on, and also whenever the screen is off (WiFi stays on when the screen is off, if within range of one of my networks). Even with the Mobile Network off, Gmail still pushes.

The widget I use for brightness is called "Auto Brightness". It's not the most sightly of widgets (a yellow light bulb), but it does exactly what I want it to--Auto Brightness when activated, and my default brightness (10%) when deactivated. Anything involving sunlight gets auto brightness, everything else doesn't. 10% is the sweet spot for me, as 0% is too dark, and 20% and up is unnecessary with indoor lighting.

I use the live wallpaper "Light Grid", and heavily rely on Folder Organizer.

Once the battery breaks in, it's fantastic.
 
My battery was having no issues. Then last night I went to bed with it at 61 and woke up and it wouldn't turn on because it had died. Wtf? Edit maybe it's relevant that i just moved in to my new dorm with terrible cell service. Is it really possible to go from 61 to 0 overnight on 3g just doing nothing because of a bad signal in about 10 hours?
 
I'm beginning to think my 3VO is a bad Apple. I charged it all night, its been 5 hours, been watching tv and moderately using it, some texts, some surfing the internet, couple phone calls, about 20 minutes of talk time , and my battery is on red. 10 percent left.

Been bad. Gets to red battery quick.

How long do yours last?
 
If I did all you just said, then my battery would be right there with yours. It also depends on your settings, how you manage your syncing, how you control data connectivity, yada yada yada...
 
Yep, thats why I have the Gorillagadgets 3400mha battery and love that I can have autobrightness on, listen to pandora, do anything I want in a day's time.

I'm really thinking of getting the Gorilla Gadgets battery. It seems to be good for the price.
 
If you want to use the phone like it should be used...Get the Gorilla Battery or the Seidio...I have the 4000 Seidio myself and recharge every two days...No Extra Batteries no Chargers to carry around...

As far as batteries from Ebay...Its hit or miss...But most of the cheap stuff on there...(There are no deals...you get what you pay for...)...Most of the times the batteries are not what they are really listed as...Seidio has never gave me a problem...

With Ultimate Juice installed you can run the hell out of this Phone...
 
hi guys im new to here, my evo 3d battery is decreasing arround 1% in 3 to 5min.. is this normal?? i know this phone is a mini computer, a dual core processor.. is anyone facing the same problem or my battery has a problem and need to be fixed?
 
Fully charge, put in airplane mode for a few hrs and see if it still depleted as much. May be an app. My battery wasn't that bad before root

FYI I read that it's healthier for these batteries to charge more often even if you still have plenty left. I know i have like 70% or more most nights but still charge it anyways cause that's better for the battery in the long run.

Won't make much difference. The only major factor affecting the longevity of your battery is heat exposure. Less is better. That said, there's absolutely no harm in charging all the time, regardless of the charge level.
 
What I read with about Lithium Ion batteries is that it's not as healthy to discharge the battery every time rather than just charge it when you can.
 
to all of you having issues with your battery life, root your phone and get on the Myns twopointthree rom and run Ziggy's kernel. This thing is amazing! I can easily run 12 hours with moderate to somewhat heavy usage.
 
Sorry to say, but you don't have to root to better your battery life to 12 hours. I am getting 24, 36, 48 hours with moderate usage on my stock EVO 3D with all the latest updates.

Most, if not all, modern Li Ion batteries have voltage monitoring circuits that will shut off the battery if you drain it to a certain threshold. That threshold, unless the engineer has gone insane, is above the voltage level where plating occurs.

So yes, if you took a plain ol' Li Ion cell and drained it to near 0 capacity (IIRC, below 2.3v), then yes, you could damage the cell. Plating could occur, reducing the capacity and increasing the chance of an 'event', gasses could be released that cause the battery to be puffy and more at risk of an 'event', or a mix of everything.

But no reputable company sells Li Ion batteries without control circuits that prevent you from discharging the cell too low. So if you drain your battery until Android the unit down or the battery control circuit just shuts off power, the battery will still have a bit of juice left in it, but the control circuit won't let you use it.

running viper rom and following his quick tips on getting the most out of the stock battery, this thing lasts a full 14-15rs with HEAVY use.. thats games, ALOT of texting, tune in radio, internet browsing. last night i wanted to see how long i could run tune in radio so turned it on before i went to bed, volume a little less then half way, phone was at 58% and was still playing 8hrs later with about 9% battery left!

Super,

I would love to know some of the tips and tricks you're using to extend battery life. I'm getting nowhere close to 14-15 hours of battery with light to moderate use.

I'm not kno on Viper. I run Miui Rom with ti ex kernel.

Would like to see if your tips could work for me.

Why? The problem is the definition of "Moderate use." I have gotten over 24 hours of battery life when at home on the weekend. Definition:

1) WiFi for all data
2) Read email on four different email accounts (email is light on weekends.. maybe 40 messages per day).
3) Update twitter every 15 minutes (again, I follow accounts that have light updates on weekends.. maybe a dozen per day)
4) A bit of web browsing/searching (maybe an hour, per 24 hours)
5) No gaming
6) no photos
7) no watching or taking of videos.
8) no facebook
9) no other social networking
10) no music playing

So do you think this is low or moderate usage?

The point is, you can get 24+ hours of battery life. If your usage pattern includes streaming video, using the camera a lot, playing action games, using your data connection over 3G/4G for hours a day (especially over a connection with only a couple - or less - bars) then you will not see 24 hours (maybe four!).
 
Sorry you feel that way. Attached is my last two days of use. 32 hours and counting.

You can tell from the flat line graph when my phone was on but not in use while I was sleeping at night, and with moderate use I am at 32 hours plus.

Sorry your not doing as well.

EDIT: Added "Most" of the program use info screen shot. There were two other programs towards the bottom of the list that I would have had to do a third screeshot for.

So I've had the seidio 4000 battery for while now, thought I'd post what I'm getting with moderate usage. Please note that the battery was at 33% when these screenshots were taken.
