[Q] Android mail eating battery! Please help!

This may have been addressed, but a search didn't reveal anything exactly like this. Please bear in mind that I'm an Android newbie!
I bought the Incredible 2 last Thursday. No rooting, nothing weird, still mostly stock. This morning it's running very slow, screen transitions jerky, etc. and even text based email takes minutes to open. I messed around in settings, and notice that Mail (com.htc.android.mail) is using 48% of my battery, more than twice what the screen is using! I force close, and the phone speeds right up, lag is gone, screen transitions smooth but, minutes later, Mail comes back on line and the phone goes to crap.
I've used more that 1/2 my battery in two hours. I notice that the uptime is 1 hr 58 minutes, and the awake time is 1 hr 44 minutes, so I assume that the mail app is also preventing the phone from sleeping.
Any advise will be greatly appreciated!!

This may sound obvious, but did you try resetting your phone? Turn fastboot off (settings > applications > click fastboot so it is unchecked) then kill mail, and before it has a chance to restart hold the power button, then shut down. The restart option might work, but for things like this I prefer a good old fashioned power down, power up. Anyways, power your phone back on by pushing the power button for two seconds or so. Then see how it goes. This is an error that I have not heard about, but a reset is a universal problem solver. If it doesn't work, tell us what kind of email accounts you have set up (pop, imap, exchange) and how many, and also the settings for checking the mail.
Hopefully the restart will fix it though.

Thanks! My limited Android knowledge told me to try a restart, but I actually didn't know how on the Incredible 2!!
Anyway, the problem went away for a couple hours, then came back!
I use a POP server for my work email, and gmail for personal. I really don't understand this, as nothing has changed since yesterday, but the phone has slowed to a crawl!

Try a third party email app. I don't know of any offhand as I only use gmail on my phone. My gmail account checks my imap account on another host so it's all together, and I can distinguish which account is which on the emails through gmail tags.

Umm I think this will require a factory reset, because you can't uninstall stock mail nor freeze it without root

You can temp root, and freeze the stock mail app if that is the way you decide to go. Instructions found here http://forum.xda-developers.com/showthread.php?t=1068544. But that sounds more like something faulty with the software, because like I said, I have never heard of that happening before. I would take it back to Verizon, complain incessantly, and point out that you could have fixed it yourself if the phone had an unlocked bootloader
Do you have them set to check mail constantly, push, or are they on a delay? Can you use imap for work instead of pop? I have four accounts set up on mine, including an exchange, and three imap accounts. The fact that it just started happening leads me to believe something broke in the system, though. A factory reset and re-flash may indeed fix the problem. Also, do you have good 3g coverage most of the day? Check your time without signal under battery status in settings. Click on cell standby and it should give it to you. Or are you using wifi most of the day?
Sorry for the rambling questions, just writing stuff out as I think of it. Trying to narrow down what the problem could be.

Thanks, again.
I'm using the mail settings that the school requires, so can't change them. Currently set only to update when the app is opened.
I generally get good cellular reception at work, and I have wifi as well. I've been trying it with or without wifi today, with no changes. I'll try a reset and see if that helps.

I just mentioned trying another app because I don't see these problems and I do not have the stock mail app configured in any way.

I've had the Inc 1 and now the two. I've always turned off the (auto sync) this would require yyou to open your mail and manually refresh or of you use the sync all widget it works that was as well. Seems to save a ton of battery only drawback being you have to manually check it. Ie. No mail notifications. Just a thought maybe you want to give it a shot.

Thanks, everyone. Using a combination of all your advise, the problem is resolved. I factory reset the phone, then installed only my gmail account. This worked fine all of yesterday, so I finally got off my butt and learned how to use gmail to read and send my work email last night. That seems to be working well. I'm still getting email notifications, but gmail is only using 3% of my battery, as opposed to the 48% that Android mail was using.
Still don't know what caused the trouble, but I'm very pleased with the solution.
Thanks again!!

Email battery problem also on Nexus S
I have also the problem that the standard email is consuming the biggest part of the battery - mostly over 50%. I use an exchange account and a pop email, but both not synchronized automatically (manual sync interval), and I do not use them so often - max. one sync a day...
Anyone an idea how to improve this?

Please use the Q&A Forum for questions Thanks

HTC mail has always been a battery drainer for me. I just use the Gmail app.

K-9 Mail
I had also the problem (as mentioned above) with the standard android email programm and a so related short battery life. Since I deleted all email configurations there and installed K-9 mail client instead, battery life improved a lot. Before I could use my phone about 2 days, now it lasts for around 5-6 days...

Solution to "Android OS" consuming battery

Ok its been pointed out that "solution" is a poor choice of words but rather I have pinpointed the culprit mmaking android os drain the battery. I would like to first start off by saying that the reasn I chose to make a new thread was because the "Android OS" consuming battery thread is pretty much all over the place. Its not very informative if this bug is plaguing your battery life. Way too much random talk about wifi and other things. I dont think I saw one mention of adb or a logcat in that thread. No one is really doing any testing and sharing information so that we can get to the bottom of this. I would prefer if this thread was more informative where you posted what you did and what the result was. Mods if you feel as if my post should be in that thread then so be it. Enough with my rant here goes.
The problem I have found is that something in the google account is making the suspend function go bonkers. When the phone attempts to sleep it ends up spiking the cpu pretty hard for a good amount of time too. This is why some of us are not getting the phenominal battery life others are boasting about. The temporary solution I have found is to do a reset and not put any google account information in. This is why when some people have reported they did a reset and they still have the problem that its still there. Dont use your gmail. I know I know... the solution kind of sucks but its temporary until a real fix can be pin pointed. I am trying to get to the bottom of this as fast as I can. Thanks to Sprints new return policy I would like to do so as fast as possible. I have tested this on 3 phones so far. On all of them I did a reset, and then only installed the amazon appstore and watchdog. The amazon appstore was so that I could get watchdog. No cpu spikes alerted by watchdog on any of the 3 phones for the whole day. At the end of the day I added the gmail account that the user had been using to one of the phones and watchdog began to alert shortly after the screen timeout kicked in when the phone was attempting to sleep. Reset the phone again without adding a gmail account and the problem was gone again. Yesterday I began gradually installing other apps that I use day to day to continue my testing such as maildroid, twitter, etc. I got through the whole day on 1 charge with no problems. I cant remember how long I was on wifi but lets just estimate it was between 4-6 hours. This is with two accounts pushing to maildroid using IMAP idle so it doesnt have to poll a server which is better on battery. The official twitter application also uses push. I also have groupme installed which I use for my business to communicate with team members throughout the day. It is a chat application and it also uses push to send messages. Also I have left all the stock widgets in tact during this whole period of testing. The weather widget is set to refresh at 4 hours i think and the news widget is on manual refresh.
My next steps are trying to figure out why certain gmail accounts making suspend peg the cpu so hard. Today I plan on using one of my backup gmail accounts that doesnt have any contacts or apps purchased. I will be posting my findings later. I do apoligize for being so long winded but I hope this post helps someone out there and helps the community get to the bottom of this bug. Thanks for your time!

You call that a solution? Not put any Google Account information in? Thanks!
/sarcasm

I have a better solution. Don't turn the phone on! I haven't turned my phone on in 3 days and my battery is still fully charged! It's amazing!

Lol glad to see my efforts are so well recieved... Ive pinpointed the problem. Maybe you can find the solution yourselves.

Ill admit the "solution" defeats the whole purpose of these phones however at least it kinda narrows down the problem and can possibly help work towards a solution.
Im not going to remove my google account but instead I mail turn off mail sync and contacts sync and see how that goes for a day.

As another poster said, no need troll. He pinpointed the problem for us. Thanks op.

You can set up the built-in email client to still sync your google email. You just will get your email through the email client rather than through the gmail app. You will also not be able to download apps, but you will at least be able to check your gmail.

Thanks for this thread!
I am far from being able to provide in depth troubleshooting, but if it helps anyone, here's my progress so far. Two things:
1. Before seeing this thread (without changing anything) I had the phone in airplane mode for about an hour in my pocket and when I checked the battery stats, for the entire time the phone was in airplane mode it was also awake. Screen off.
2. After reading this thread, instead of disabling the Google account, I just un-checked "sync" for everything except gmail in Accounts and Sync (so calendar, contacts, books, etc. doesn't sync unless I manually do it)
After about 2 hours with this setup, android OS battery usage has dropped way down.
Hope this helps someone!

Good grief, you people are so ungrateful it is amazing. The OP is not suggesting you will never be able to set up your Google account. He is trying to narrow down where the problem exists so effort can be focused there rather than other places mentioned like WiFi. This thread is for us to work together to find a solution.

Exchange calendar behavior

Noticed that with every single ICS rom i tried, whenever i get a meeting request in an Exchange account and i choose "view in calendar" it goes to the right day but never shows the actual timeslots blacked out or marked in any way......
Is it the same with everyone?

With the stock ROM this is working for me. When the meeting is accepted do you see it in your calender correctly?

Under "Calendar/Calendars to be displayed" is the exchange account checked?

The inability to process and/or respond to non-Google meeting invites (Internet Calendar Sharing, or ICS, aka RFC 2445) is a long standing problem which Google seems to ignore.
Please "star" all the issues on this list. Some are 2-3 years old with hundreds of stars, yet no fix in Android.

[Q] How can I logout User Accounts on Android 4.3?

Hi Guys,
I've just bought a brand new Nexus 7 (2013) Wi-Fi and configured a primary and secondary user for my girlfriend. Now the question is how can I "logout" eaach account so the background processes related with it terminate and the user is considered offline on all social and IM applications? Because apparently both accounts stay online all the time unless I turn off the device and log in into just one of them.
Regards,
João Guerreiro

In goog,
you have a primary account, that you set up your N7 with right? Then you added a second account, right?
So go to the playstore, and there should be a list of registered users on the slide out window.. Just click on the one you want and it will be like being signed into that account. If I'm understanding your question properly.
Looking further go into users and accounts, in system settings they vary what they are called in different versions.
Heres a link that explains it better than I can

I hv 2 device user accounts which u can switch easily ..... but switching does not kill the background processes of inactive accounts and if inactive accounts has lot of windows opened ... it causes the device to respond very slow....i even had to force restart. For that matter i wanted to know if i can LITERALLY signout/logout instead is switching.
And thanks for the response. This forum has always helped me.

Ads in the Samsung Calendar?!

I just had a calendar notification pop up that said "iPhoneX is Here!"
I clicked on it and it opened my calendar and sure enough there's this entry that I never made, and it repeats daily for the next 5 days.
I'm guessing this is a third party app and not Samsung. But I've checked permissions and none of my 3rd party apps have calendar permissions.
The only thing different that I installed from my previous phone is Blurams app for a security camera we purchased and Network Signal Info app.
Anyone know of anyway to figure out which app is pushing notifications to my calendar?

Gmail sometimes automatically adds things to your calendar from emails that you receive if they include a meeting invitation attachment. Check for a matching email in your gmail inbox/trash/spam

Good call, but nothing there. Just checked spam and trash.

I just got the exact same message and was wondering that too. I used to have a problem with my iCloud calendar on my iPhone x where people could just put random events on my iCloud calendar and they would appear and now it seems they can do the same thing with a Samsung calendar

The stock Samsung Calendar app.

I would flip if I had iphone advertising on my Samsung phone, seriously, but I don't see any advertising on mine, maybe because I went over all the menus and disabled all advertising, tracking etc. . Those are usually in privacy settings, or similar. If that doesn't work try to guess which programs could be doing this and limit all the permissions for them. Also you could create some throw away gmail account to register the phone, that nobody knows and you rarely get any emails.

That's not advertising from the app. Common sense would tell you that Samsung would not advertise for an iPhone.
There is a way that people can add events to your calendar without your permission simply by knowing your email address.
It is indeed coming from your Google account.
To prevent this you need to turn off the ability to accept events without confirmation or permission.
Here is a good resource.

Yes. But what calendar it link too? Did you connect to google calendar and the message is come from google calendar?

This sounds like a spam calendar event. I just had the same issue, but mine were all in Russian. If it is, where it comes from is if someone adds your email as an invitee, it will add to your calendar even without getting the email or replying. The setting that allows this has to be fixed on a PC web version of Google calendar.
Here is how to do that, but it doesn't deal with the events already there I think.
https://howtoremove.guide/remove-spam-in-google-calendar/
To mark an event as spam, I can not recall the exact steps, but it was something like in Google calendar on the phone, open the event without clicking any links. Hit the 3 vertical dots in the upper right. One of the options should be "mark as spam" or something like that. Or there might be "more actions" then the mark as spam option.
I can not find the original website where I learned that. But it fixed my problem since it blocked the spammer. There does not appear to be the same functionality in Samsung calendar, so try doing on the website version from a computer.

Gotcha, sorry. Yes, it shows it came from my Gmail address (Google Calendar), but it's greyed out. And. You can't edit the entry, either. Just delete it.

Sorry if that came off rude I did not intend for it too. It just seemed like the discussion was going on a route that made it seem like it was the Samsung app rather than a Google calendar issue.
Well, truth be told I got one of these two days ago. The same exact one.
There are tons of breaches that have been happening in recent years. You can use https://haveibeenpwned.com/ to see if your email address was included in a breach. (This does not contain all recent breaches but it has a lot)
I also have noticed a crazy uptick in back to back to back robot scam calls. The other day (same day I got the calendar spam) I was at work and a client of mine and a customer of his all had our phones ring at the same exact time. They were all "Scam likely". While they were different incoming phone numbers it was literally at the same exact time. Things seem to have really kicked up a notch when it comes to spam. At least it seems so.

Yeah I actually checked that site about a week or two ago. Was taking some training on internet sources in criminal investigations, and they showed us that site. My email address has been compromised like 14 times, LOL.
And YES to the robocalls!! I usually just hang up on them without answering. But the other day, as soon as I hit decline, it rang again. I mean IMMEDIATELY. Did it three or four times. That's a new tactic.
It seems like every time they say the cell carriers are cracking down on robocalls, they just increase. I can't even answer my ****ing phone anymore.

Thanks for the link to this thread. Yes I saw this in Samsung calendar this morning too. I have never seen anything like this in Google calendar and I don't have any spam emails that would trigger this.

Ive never seen this on any note phone I've had and dont see it now. Currently using just the stock Sammy calendar.
Ive had a few emails breached over time and that link above that tells you if your email addy has been comprised is a good resource. That said, even with a couple of my email addys breached ive still not seen this...

Just had the same thing. Never saw any spam emails with calendar invites, though. There were 4 events per day over 8 days.

It's a know issue with Gmail. Or "working as intended", really..

It's so weird that it suddenly hit us Note10/+ users. Maybe a coincidence, but still strange. And yup, sounds like a spam email event. Spammers/scammers are useless wastes of air. ?
