How Yahoo Mail App Affect Android Battery

Okay, I think I discovered Yahoo Mail as a major cause of battery drain on my Charge. First some background. At one point early on with the Charge I had great results of 20+ hours. That was shortly after setting up Humble and ImNuts Kernal, calibrating the battery, and installing basic apps.

As many of us do, I kept on tweaking from there. I tried various combinations of Imoseyon's kernal, EP1Q modem, and V6 supercharger and related scripts. At some point in the process I lost the battery life. I started getting 6-8 hours max! Of course at the same time I kept working on getting the "perfect" app setup. All this tweaking meant I couldn't tell what started the problem.

Anyway, I've since undone V6, gone back to PBJ kernal, and restored EE4's modem. I thought I noticed some improvement, but really it was no more than a couple hours more than before. Maybe 8-10 hours total.

So, I started thinking about how Data usage kills my battery at work. I get a very weak signal and it absolutely kills the battery. But still, I was able to get up to 20 hours before, even leaving data turned on. So, I wondered if anything was causing it to work extra hard to send/receive vs before.

Long story shortened (a little). I considered the Yahoo Mail app with it's "push only" setup. This is something I didn't have setup right away. I'd used the built in email. So, after disabling "Notifications" in my account and re-enabling the built-in mail notifications, I've recovered my battery life! Today I've been going 15 hours and I've still got 31%. And that was with fairly heavy use and leaving data on all day!

I stress that the Yahoo Mail setting is the only thing I've changed since last week. I've been very patient to make one change at a time so I could track this down properly.

So, anyone with primarily weak signals care to test this theory as well? I really feel this did it, but could use some confirmation considering all the previous variables. I'll do some further testing myself this week. Maybe a day with and a day without. It's difficult not to just jump to GummyCharged 2.0, but I really want to confirm this issue first.

Some confirmation can be found by googling the issue: "yahoo mail android battery drain". Hope this may help someone else.

Yes I have notice this too. I live in a non 4g fringe 3 g area and my battery drains fast as well. Yes I have yahoo mail and have since uninstalled it and have the stock email app pull my mail from yahoo. Also any app like yahoo messenger also runs in the back ground and no matter how much u do a force off, it restart a few mins later. Here is a list of app that run in the background.

A. Yahoo mail
B. Yahoo messenger
C. Live holdem poker.
D. Maps
E. Gallery
F. Gmail
G. Stock email app
H. Music
I. Search
And of all the rest of the stock functions. I wish that most of these apps would only run when you launch them and when you close it, they would stay shut off untill needed. Freezing the apps work but you cant use them until u unfreeze them. I know that this is done for a reason, so that there would be no lag. So I guess these are some of the things we have to live with.

One of the big mistakes samsung did with the charge is not install enuff onboard memory. So when you have all these programs running it does cause a lag and massive battery drain on our phone. As far as the data connection, I can not complain about the phone cause this is a problem that BIG RED is causing an additional drain on the battery. The mighty no connection and searching for service LOL..

END RANT..

Glad to see it's not just me. You'd think a "push" service would use less battery, but in the case of yahoo mail it seems the opposite.

I'm not as worried about ram usage as network usage though. With a custom rom it seems fairly responsive. It's the network use that I wish we had more fine control over at the system level. If I could just make some of the offending apps act less aggressively that would be great.

In fact, I wish the OS had a smart signal monitoring feature that could tell apps to throttle back until a strong signal was available.

I noticed this too. It was causing a huge drain! The only reason I got the yahoo mail app was because the stock mail app wouldn't let me sign in to my yahoo account. Does anybody know the reason for this? It worked less than a week ago...

The stock mail app is working fine for me. Never had trouble logging in. Maybe try from a computer to see if it needs to verify your account or something?

So far today I am using 5% per hour with yahoo's app disabled and very heavy usage of phone and screen. During one hour with little use it only used 2%. Very acceptable. I'll try turning yahoo on for the afternoon and see the difference.

What i did is uninstall the yahoo mail app and load the stock email app, you can do all the same stuff with the stock email app as you can with yahoo mail. Also I found that the email app that comes preloaded with the gc 2.0 has issue with yahoo, and other email accounts ( Iam sure other people did not have this problem but i was one of few that did. So please dont flame me and say that iam the only one with this problem). What i did is pull the stock app off my tablet and installed this one on my phone, all problems are gone, i can receive and now repley, create and send my emails. I can now easily setup all of my email accounts, aol-yahoo-comcast, etc. If you can pull the stock email app that was preloaded on the phone before you modded or install any custom rom/themes. Also if you have yahoo messenger installed, get rid of it. I found that between the yahoo mail and messenger app my battery life was almost cut in half.

Update

So, I finished my testing:

Yahoo Mail app notifications turned off:
Used 35% battery in first 6 hours of day with heavy use of phone

Yahoo Mail app notifications turned on:
Used 55% battery in next 6 hours of day with very light use of phone

So, simply enabling the Yahoo Mail app notifications increased my battery use more than 50% per hour. This is even though I went from heavy usage before the change to practically no usage after the change.

Needless to say, I'll be leaving Yahoo Mail notifications off and let the built in e-mail app notify me. Which it does a very fine job of by the way. It's still "push" even.

So, I'm wondering how to find other offending apps. I'd have thought Spare Parts would tell me, but apparently Yahoo Mail was hiding its network usage behind some other title. Perhaps it's lumped under Dialer or one of the mysterious user ID's that show up (1043, I think?).

Anyone know of another network usage watchdog type app for our phones that might shed more light?

I have tried and tried but cannot get Yahoo mail added to my email. I also tried to download your link but it says my phone does not support this.

I think you have to use this one to replace the one in /system/app since it's a preinstalled application.

Go into your system/app folder and delete the stock email app that you have installed. Of course by deleting this you may/may not lose all of your accounts you have setup. Then download the link and install this one ( also make sure you rename the app to Email.apk ) i dont think you have too, but if you have a problem installing it, try it, you never know). Problem is since you allready have the email app installed, it will not let you install another one. I know this to work, for i have tried several different version that have been floating around these site, and they are all the same version, So i pulled the stock email app that i have on my Gtab and used that one on my Charge and it works great. push/pull-reply-create all works now, as well as being able to create all email accounts that i have without any issues. Just make sure once you have installed that you restart your phone for all to take into effect. Look at the app page on the phone and make sure you have the white envolope w/green @ symbol on it. If you do and you launch the app you should have a page loaded that has all the different email accounts that you can use to automatically setup. Just enter you [email protected] account and the password and then click next and if all setup correctly it will prompt you to pick a nickname and name to use for that account. Finished.. LOL

Not to sound dumb.....I like the stock email app as well and it does not work on my phone. I DL your file. now I place it on my sd card and flash it, is that how I install it?

No you dont flash it. Once you delete the email app you have in your system folder. Then you just click on the email app to install it. Of course you will have to redo your settings, and then you should be good to go.

Did you try to add it manually as an IMAP account? Enter your email address and password and then select manual setup or whatever that option is. Google the SSL IMAP yahoo settings for android and you should be able to get it. That is how I got mine working.

here is the email app i used, let me know if it works for you. i have about 25 email apps and hope i gave u the right one..

Thanks it works, you safe my life.
