Optimize your Droid Eris battery life (READ THIS)

Alright so I just turned off auto-backlight, and I'm starting to notice improvements.

Does Wi-Fi burn more battery than Mobile Network?

What happens if i uncheck "Enable always-on mobile" ?

I believe wifi burns less battery than mobile. I had wifi on over thanksgiving at my girlfriend's family's house, w/ mobile off, played with the phone constantly all day, and put it on the charger at night with 15% left.
 
Just one last friendly reminder for those putting it on the charger b4 it's dead. As said b4, let it die and watch your battery life soar. My wife's just went for 43 hrs on her last charge w average to high use...lots of internet and slacker as well. Please try this b4 giving up and returning it...it works!!;)
 
Not sure if this was mentioned, but a huge thing I noticed was;

"Disable auto backlight" - You want this to be checked. And drop the brightness down to like 25%. It still looks bright as ever, but now the phone won't constantly be adjusting it's brightness. This is a trick that works on the iPhone as well.
 
I have had my Eris for one day and I am very concerned about the battery life. I checked my always on and it said 49%. I did all the tricks that were posted here, did a reboot and my always on went to 100%. HELP!
I am very close to returning this phone, could someone please offer advice. I am a complete novice to smart phones and I may have bought way over my head with this phone. What is handcent and why do I need it? Do my applications keep running after I exit out of them?
 
So my battery life was a little scary for the first few days of ownership. I was recharging twice a day. Here are the changes I made, bringing awake time down significantly from the original 35%, and finally getting a full day's charge out of the phone:

1. Got rid of Messages widget, replacing it with a Handcent shortcut (just because I like it better, not because I think it uses less battery). Turned off notifications for Messages app.

2. Set personal email account to check to check every 15 minutes, work email account to check every 30 minutes, and turned notifications off for the Gmail app (again, personal preference says I like the Mail app better).

3. Uninstalled all app-killer type apps (I had three) and stopped worrying about app killing entirely.

4. Set Twitter (HTC Peep) to check every hour. I have the full-screen widget running so I can manual refresh if I want.

5. I made no reductions whatsoever to the haptic feedback or any vibration at all. Everything vibrates and lights up still. I also never turn off wifi or mobile network.

6. Turned off auto backlight and set it to 25-30%, which is really bright almost all the time.

7. Ran the phone til it died the last 2 days. Charged it all night afterwards.

I am now getting a solid 12% awake time on the phone! My ultimate suspicion is that the brightness setting change and dumping the app killers did the trick, with the full discharges helping lots too.

I wanted to give you some clues as to what has worked for me. I hope these help you get better battery life out of your Eris too! :D
 
Ok, so this is kinda important, I realised this this morning.

When you let your phone die, and then plug it to charge up...even if you wait 10 minutes the awake time is still going to e 100%.....because it's plugged in!!

Let it charge up a bit, then unplug it, and then hit sleep, and wait a minute. That's the real way to tell.

My awake time is 38%...and I'm using Handcent :)
 
It appears that those that are getting good battery have either unchecked "mobile network - always on" or have set their email to check less frequently or at some interval like 15 min. Is anyone using push activesync "as it arrives" and getting good battery life? I suspect that the software is not efficient enough to allow for always on real time email delivery without a huge hit on the battery. I would love to hear otherwise though.
 
I know it's even a huge battery killer for the iPhone...so I figure it does the same to the smaller Eris.

Honestly, I've been f***in trying to kill my batter since last night and it's still creping donw at 11%. I have all apps open including youtube and pandora and maps and 3g on and wifi on...


My theoery: It depleats quickly from 100%- like 50%...once it get's lower than that, the battery is a beast.
 
I'm stumped/ My awake time is always 100% Uninstalled weatherbug, disabled auto backlight, wifi and bluetooth off, unchecked always on mobile network. No help. Any suggestions?
 
do you have youmail app? are you using the visual voicemail app? are you using the stock, original, "messages" app for text messages?
 
:mad::mad::mad:also found a new trigger that awakens the infamous messaging app - TEXT messages from verizon. paid my bill today and got a text notification confirmation. then went right back to the 100% awake problem. spent another 2 hours undoing it.

VERY FRUSTRATING :mad::mad::mad:
 
a text is a text. if your 3rd party sms client (handcent, chomp, etc) is set to default you should have no problems.
 
Not giving this as a solution to anyone's problem but just something you might want to know:

when you are charging your eris from the computer (or have it connected in general), even when the screen is blank it is not sleeping.

This had me worried for a bit cuz i had rebooted it and was charging it on my computer and it kept saying my wake time was 100% even after i let it "sleep" for several minutes at a time. when i took it off the computer and put it on the wall charger wake time started going down. basically dont freak out if wake time goes up while it is connected to your computer

I beg to differ. This morning I pulled it off the charger at 8am and it was at 80% by 8:45. Last night I let it run down and die. Wfi off. Gps off. Nothing unusual running. Had this phone a little more than a week and this is the worst it's been. Maybe a lemon battery, who knows.
 
do you have youmail app? are you using the visual voicemail app? are you using the stock, original, "messages" app for text messages?

No, I don't have the youmail app, and don't use visual voicemail.. I stock message app but I don't text message. I have 10 apps loaded. I don't think any run in the background.
 
great find on the plugging into computer for charging. wish i had figured that out before....i may have chased that ghost for a bit...:eek:
 
use advanced task manager to see if the messages app is running even though you dont sms. if it is, you still need to run the sms fix thing. you also need to delete any sms widgets from your home screen.

Stock message app is always running. NOte if you try to kill it it just comes back.
 
not running on my machine. i did the sms fix thing and it is never running in the background.

Follow the sms fix procedure, make sure you delete the widgets from your home screen and make sure you set Handcent as default sms.
 
Ok, forgive my ignorance....what is a SMS? What is handcent and why do I need it? I've been reading the threads about battery life and get a bit confused since I don't know the language. :confused:

Also, can someone tell me how to change the frequency of checking mail? If I turn off mail notification does that also turn off text message notification?

Thanks for your patience!!
 
sms is text messaging. I don't know if only some phones are affected by this but I have no problems with anything causing excess awake time and I use the stock messaging app.
 
This is just on one charge. I posted my suggestions on how to save your battery life on one of the earlier Stickies on Eris battery life. I'm still using my native SMS app, my awake time hovers between 18%-21%. I don't turn on Wi-Fi unless I need it. My Background Data is turned off in Data Synchronization>Google>Background Data. My screen timeout is 30 seconds. Hopefully this helps.

P.S. During the workday, I only make a few calls on the cell, and surf the web on my computer, so that could contribute to keeping up my battery's life. Your mileage may vary.
How does turning off background data effect the phone?
