I'd like your opinion on this. Today I had my phone mostly at silent and the display was off most of the time, I was attending a workshop and pretty much did nothing with the phone. Before starting, it had 100% battery but when I came back it had dropped to 63%.
Not only that, it also used 3MB of B/W today over the cellular network(Using netcounter for this). For the B/W I got 1 e-mail account set to sync contacts and e-mail as the items arrive(Push mail) in HTC Mail. Now until a few minutes ago it was also syncing News, stocks and weather under HTC's default settings.
I have VillainRom with 17_2 baseband, the phone is pretty much new and the battery is calibrated.
Note : I'm mostly talking about a period of 8 hours.
OK I flashed LeeDroid ROM and 30_2 radio. I also tried to re-calibrate the battery, but it seems it was calibrated since after removing the phone from charger, shutting it down and plugging it back in it immediately went green.
Now I got one gmail account which has nothing to sync, one exchange activesync account set to sync as mail arrives(push) as well as contacts, one HTC Facebook account set to sync every 2 hours, weather to sync every 3 hours and that too only of my location(I removed other cities). I also got Nimbuzz running and Wi-Fi sleep policy is set to "never", brightness is automatic. Hopefully this'll keep my battery happy.
Lets see how it goes, I plugged it out 1 hour ago(It was at 100%), now it is at 92% although I believe the 90-100% span is kind of delicate and runs out quickly. Not to mention that I also browsed for a few minutes.
Totally agree on the randomness of the battery even when charged. Some days I have a wifi surf whilst having my morning poo for 5 mins and I'm down to low 90's/high 80's. Today I'm still on 99%. My poo lengths don't change much so something flaky is going on.

Heh, I know what you mean.
Its been a bit more than 4 hours and I've had a few calls, browsed the web a bit and read 5 mails and send/received 4 texts. Nimbuzz has been on constantly along with the Wi-Fi and I'm having 82% battery. Seems OK considering the usage.
Upgraded two GSM Nexus to 4.2 via the OTA. Both phones have major battery drain. 48% Android system usage of the battery after 20 hours. Has anyone noticed these issues? Screen shot added. Something is very odd.
Edit: when I got home I checked the wife's phone, 68% exchange services battery usage and 6+ hours of keep awake.
Nothing is odd. You're not using the device, so android uses up the rest. 100% has to be divided. Happened to me last night: android system was at 70% when i woke up - so? I hadn't been using it, so that's expected. But i only lost like 5%, WiFi on, alarm on, flashed the rom like yesterday. I will only know for sure when i install back bbs.

But this was not overnight and I do use my phone throughout the day a decent amount. Before 4.2 the screen was always 50% of my usage. Something is funky. I also use to get about a day and half, now its dying under 24 hours.

yes I have an exchange account setup to the stock android email app. Could this be causing the issue?

Same issue here with exchange services. 68% battery usage and over 6 hours of keep awake. I did a hard reset and Resetup account with 10 minute refresh instead of push. Working so far but only 9 hours in.
Frustrated that a fix was presented to Jean Baptiste in Gerrit and he said he it conflicted with AOSP. But didn't offer a fix. How is android going to compete in the corporate world with crap like this.

Yours is better than mine. I am not alone. :crying:
I just did a hard reset. It looks better now. Never had this before. I will keep updated.

Thanks for this. Found the root cause after doing research on this.

that was indeed my objective, making you search for it. thanks.
OP, don't have that exchange account fetch for new email. Set it to manual update and the android system usage will be reduced. Try out out and report.

I ended up removing the account and doing a hard reset. When I resetup the exchange account I used 10 minute refresh instead of push. No issues for the past week.

I had to do a hard reset. Removing and adding the exchange account did not work.
Hi,
I have Exchange set up for my Galaxy Nexus running jellybean 4.2, I can't recall if I had the same problem before the upgrade, but I don't see the phone numbers or other details except for the email address from my exchange account appearing on my phone. Anyone has the same problem?
why does the battery suck?
i charged my nexus up to 100 %, i unplugged it had wifi off screen dim and used it for all of 2 minutes. after 15 minutes i had lost nearly 10% of my battery life. im using the 2100 mah battery too. what can i do to make this better? my razr m lasts me almost 2 days, this phone barley gets 5 hours
I can add to this aswell. Untill last Saturday I was on 4.2.1 (Custom ROM: Codename Android). All was well, had about 2 days with one charge, using Y! and Gtalk messenger, here there exchange mail download, and some browsing, sms, calls. No background sync, no other app that syncs. All via 3g, never wi-fi.
Since I have a 4.2.2 ROM, JBSourcery 5.1 with franco kernel, i have very bad battery life. So flashed 2 different custom ROMs, made some sound and display configurations, made one sync with my Exchange. So background sync is off, 3g on, nothing else, did not use the phone AT ALL, left it on the table, and in 17hours the battery was done, 100% - 0%. What is going on ? Did not even install any apps, just to test the battery life, to see if it makes sense to remain with 4.2.2. Untill now, disappointing.
I spent a day with 2g connection, and the battery life is normal (for me), after 19h, it lost 51%. So aparently the 3g has huge battery drain. Any ideas, where to start to check ?
If:
7% battery = 15 minutes screen-on
Then:
100% battery =~ 3.6 hours screen-on
That's pretty standard for the CDMA model with the 2100 mAh extended battery.
I have been using a N7100 Note 2 from Vodafone for about 4-5 weeks now and the battery life has been great. About 3-4 days ago I found out that Exchange services was the top consumer of my battery. This happened out of nowhere, without changing any setings. For example now I'm down to 3% battery. Phone was 14 hours on battery, one and a half hours screen on and one hour of phone calls. Top battery consumer is Exchange services with 38%. I searched other forums and other users are reporting same issue on different phones, but all of them running Jelly Bean. Has anybody else run into this issue? I was so much enjoing my battery life, but now I'm going crazy.

This happens on many platforms. iOS is not immune. Try delete and re-add the exchange account and let it re sync.
Yes, happens to me randomly. Mainly because the sync mode is push. Now I set to sync hourly and no issue.
I deleted the account and readded it and it does the same. What annoys me is that it worked right for 3-4 weeks than for no reason this behaviour started. I hope they will fix this bug. I don't want to limit the capabilities of the phone just to make it work right.
My battery eater was the latest Google Maps update,everything returned normal once uninstalled the it,have no issues with the Exchange Mail,its both setups are Push all along.
In my experience, turning of Calendar and Contacts sync helps.

I read in one of the thread that disabling Contacts helps. I've NOTE 3, and my battery drains so badly that I am so embarrassed that this NOTE 3 called to be beast comes only for 2-3 hours after full charge. I am heavy user and my Corporate Mail syncs everything.
I disabled Contacts and I could see improvement. My phone comes for 4-6 hours now. Disabling Calendar is not good since its so essential if you are using it to see your schedule everyday of your life.
Need your help to know if there are any other way to extend battery life?
Is it 4.3 android bug or even 4.4 KitKat is also facing the same issue? I didn't had this issue in NOTE 3 when it was 4.2.
i freeze exchange sevice thru titanium back up
This just started a couple of days ago and I honestly dont know why it started. I noticed that my battery started to drain A LOT. Discovered that the Gmail sync was in continuous sync for long stretches at a time. Like a half hour of syncing then off for two minutes then on again for 20-30 minutes then off again, this goes on till 3 hours later my battery is down to 51 percent. But this keeps going till the battery is dead. I have turned off many of the play store and google.play syncs to just keep the email on and it still does the same thing. Gmail is the second most battery user right below Screen. But screen gets turned off and the Gmail stays on even when the screen is off. I have to turn Gmail off manually and finally the "sync" circle on my notifications tab disappears. Any one has any ideas? Thanks.
EDIT: Fixed. Read on another forum to clear the cache in the Gmail app in settings. That is it and it worked. Aaaaargh! Im glad it worked but its so frustrating when it is soooooo simple.
Hello all,
My battery is getting crushed by Email sync, 22% this morning, CPU wake time 2hrs on 5hrs battery time. I set it to push two accounts. I've got to have it for work.
I guess the T-Mobile Edge has had this problem. Anyone here that can offer a solution?
I had the same problem on a Note 3. When I unchecked the contacts sync option the problem dissappeared.
I use exchange for work and sync is set to 1 hour. I dont seem to have a problem. I havent charged my phone all day and still around 50% battery left (13 hours or so).
The problem is when you set it to Auto(push).
I set it to sync every 2hrs and my battery is waaayyyy better now. I don't like that I have to manually check emails for work though, I can't let messages sit for two hours with no reply during the day. I read after I posted that Samsung is allegedly aware of the issue and is hopefully fixing it.
