Battery life worse after FRF83

Ive noticed a significant decrease in battery life ever since i updated my phone to FRF83. I can leave it on at 100% and it drains down to 75% or even lower the following morning. It usually drains no more than 10% if i leave it running overnight.
I dont have any apps running in the background, and my task killer is set to auto kill 3 mins after screen blankout. Auto refresh is, and has always been on since the day i got the phone though.
I manually updated to FRF85B and the battery life is still as bad as ever. Ive never gotten this problem with android 2.1 or any of the earlier froyo builds. Someone care to tell me whats wrong? Ive heard others reporting that their battery life has increased after updating to froyo, why am i getting the opposite?

I have this issue because of my exchange server.

Ive never set up and exchange server on my phone. The only constant apps that should be auto syncing are gmail, calander and twitter, which is set to refresh once every 1 hour.

Same for me, battery life sucks lately.

Then there are people reporting that their battery life has increased after updating to froyo. In fact mine was ok at first, until i started using FRF83 onwards then it all started to go downhill. This morning i woke up with the battery at 44% when i last saw it, it was at 90% the night before. It drained that much overnight and its not supposed to happen!

Mine was very good since updating to froyo ( starting from first builds leaked). Its very good now too, better than before anyway. I used to run of juice by 9PM, now i have ~ 20% left with the same usage.
Check out what apps are consuming the battery, i got terrible batt life when i tried the droidx live wallpaper.

App usage are the usual stuff.
Display being the highest, followed by android system, then cell standby, phone idle, twitter, android OS, launcher pro..etc
something seems to be sucking up my battery and i dont know what

I'll be the first one, I guess - I blame the task killer. It's widely known that you shouldn't need a task killer, unless you have some rogue app.

But if your task killer is set to auto-kill on screen-off, even if various apps restart then that should only be in the first few minutes and shouldn't reduce the battery that much.
I have taskiller installed but only for manual killing of problem apps (a rare occurrence) and I have noticed poor battery life since moving to FRF85b - didn't notice anything of the sort in the Froyo versions before 85b though.

Well i just uninstalled task killer, i'll leave the phone running overnight again to test the battery again. But from the looks of it. It seems battery life has improved slightly, but it could be just me.

Yeah thats true. It shouldnt suck up that much battery cos it only kills apps once. It could be an issue with the task killer causing it to drain the battery, because after uninstalling it i think the battery lasts a little longer. But i'll leave it running overnight again to confirm.

My quick story:
- frf72 and earlier - about 12 hours battery life for me. Used task killers, 2 emails on push. WiFi, BT off. Also tried juicedefender and setCPU. They made my battery life even worse.
- frf82+ (now frf91). Read up on how Android manages tasks and power. Got rid of all the task managers, setCPU and JD. Only use OSMonitor every once in a while to see if any dumbass app using up CPU in wakelock. So far none.
- EVERYTHING is ON. Wifi, BT, GPS - always on. I never use 2G, it's always 3G/HSDPA. GMAIL on PUSH, Exchange PUSH or 10minutes (no difference in battery for me)
- After a 24-hour test (from which 8 hours were on standby at night) I lost 80% battery life, so 20% still remain.
My advice: uninstall anything like setCPU, JD or taskkillers. Let Android handle that. Install OSMonitor and make sure nothing's in wakelock. Wipe cache if you want. If you're not getting 18-20+ hours, perhaps time to calibrate ur battery.

Thanks for the tip, just installled OSmonitor. The interface is pretty messy! But at least i understand whats going on. So all i need to do is keep track of which apps are at the highest load?
Is it really necessary to kill unwanted apps (Twitter, goggles, gmail..etc) because they are taking up RAM to improve battery life while idling?

OR you could just take Paul's advice and not use a task killer. My money is on him =)
FAQ: Why You Shouldn’t Be Using a Task Killer with Android

Wow thats a very informative read! Thanks for the link. I too also thought that an unwanted running task means i need to kill it to free RAM in order to speed things up and improve battery life. Didnt know im actually doing it harm.
Looks like i'll ditch my task manager for good and have faith in the OS.

Using LauncherPro Beta? I think some battery issues have been traced back to the way LP is handling updating widgets right now. Hoping for an update to fix it soon.

Well guess what. I just used the phone for an entire day and left it on since last night. It dropped down to 25% when i got home and was about to replace the battery pack. So it looks like task manager was the cause of the problem.
Launcherpro doesnt seem to be affecting the battery life.

Well it won't show up in the battery usage as affecting the battery. It has something to do with the widget updating not launcherpro. I removed BBC News, Beautiful Widgets and my Battery Info widget and my battery is now holding steady.
I'd be interested if you'd run an experiment, remove all updating widgets, notification widgets, etc and try again.

Another battery moaning thread

I have read a load of threads relating to the battery life, but this is slightly different. I'm on jm1 official and have been for weeks, its was fine until a day ago, now I'm sitting at work, watching the battery percentage go down everytime i look at it, I'm now talking about now when I'm using 3g, just when phones idle.
I went to sleep last night and unplugged phone before I did, fully charged. Woke up and it was on 94%....
Really my question is, is there any way to find out what's using all my battery apart from the built in function which seems to only refresh every hour! I'm not looking for juice defender or such apps

Spare parts can give you, sometimes, some rough approximations. Really, if you started experiencing issues one day, you should try to remember what you downloaded most recently, it might be poorly coded and you should look to replace it with competing software.
Also, there are somethings you wouldn't want to intentionally or unintentionally leave running in the background. Use task manager (not ATK cuz it doesn't track "running" processes very well unless they've updated) to find out if anything is running. Even the marketplace will run in the background and not let your phone properly sleep.

Also, 6 percent seems about right. 2% for all services and 3g off, 6% for 3g? I'll have to look into it when I'm not on my phone. Especially if you dress your batteries by running them down to 0s%, this is bad to do to li-on batteries, I don't know how long it takes to feel the effects but short cycles are better for the batteries health.

Ok, 3g is never on at my house I can't get it there anyway.
The only reason I run it down to 0% is because I'm using my phone and it doesn't last, its stupid to say use it in low cycles because then I'm really only getting 20% battery life anyway...
I have advanced task manager but don't really use it from what ive read I shouldn't have to. And I had thought about the recent apps I've installed and I have installed nothing much new apart from angry birds
Just not happy with the noticeable change in the space of a few days.

If consumers keep "living" with things then they deserve the crap they get. As a consumer, you have the right to be heard so make sure the people you're giving your hard earned cash to is taking your feedback and providing products and services for YOUR needs, not the company's needs.
I'm loosing 10% every night too. It's a joke and I'm hoping the updates will improve it somewhat.

ye i know. but funny thing is, it's rather random. with the same settings and nothing changed at all. sometimes overnight, it drops close to none. and some nights, it drops 10%.
i've lost 10% over 4 hours today with no usage (idle) so lol. i'm glad i'm at least getting 2 days worth of usage.
let's hope this famous froyo does something. sometime soon...

Make sure all applications are dead (ie. use samsung task manager).
Turn off apn (so that you can guarantee no apps are using data).
If you do those two things, I'm sure you won't lose more than 5% overnight.
Personally, if I do that, I don't lose more than 1% overnight.

maybe it's due to over-flashing and all. de-calibrates the battery or whatever. either way, meh.
i've probably only got this calender widget refreshing itself every 12 hours to update the day's events and my Google account on active sync. maybe some applications screwing up somewhere.
to point out, a fresh flash always gave me no problems with battery draining. (after "re-calibrating")

just updated my phone to the TEST firmware JPJG8 which is currently the latest one available thru kies which includes arabic, and have seen no changes from the original firmware the phone came with ( Originally bought from Abu Dhabi with whatever firmware that had the android market not being available )
toying with juice defender for 2-3 days my SGS laged like hell even with the RyanZ lag fix OCLF from the market and it said that i saved 1.5% more juice tho i didnt see any diff with batt, it still drained fast (full charge overnight + extra charge with phone off on my way from home to work and starting @ 100% once leaving my car and ending @ 30-20% in the afternoon about 4-5pm, need to charge a little more if i wanted it to last till 10pm T_T )
deleted it today and thought why not simply use the extended control widgets to disable the connection when the screen was off + switch off the auto sync, like how the program did but manually and amazingly batt life felt like a big nasty battery i felt the diff immediatly.
kept the program juice plotter to see how steep the batt was used to compare the results.
1. keeping my phone on 2g almost all the time except for when i need to browse the net/use msn on phone - i do use facebook/twit and i might be missing the fast notifications but 2g is good with those 2 and battery life sure is extended as i can see.
2. closing the apn when locking the phone and bringing it up when screen is on is a great idea and u can almost instantly tell ur battery life is better
3. keeping screen off as much as possible helped my batt too tho i dont like it but it works.
really noticed a diff in battery usage today so im currently backing up the phone and after a fresh format/restore session will apply root and OCLF and keep you all posted on how long the battery lasts using this method
will test for 2-3 days before reporting again.
Current Battery stat killers are
1.loads of calls
2.display due to a large amount of sms's
see you again after my test in a couple of days

I don't think jg8's a test though unless it's a new rev by kies. used it a month back, pretty awesome but I've switched.
heading to bed now, shall see what happens tonight! such adventure and excitement every night.

jg8 isn't a new rev, it was out for a while and cant be found without using the ctrl+alt+u+p (and if that = test then its not an official release) at the firmware update in kies, its a middle east version with arabic support.
ok impressions on how things went.......
voice calls = 49% with 1H 13M 23Sec
Display = 35% with 5H 0M 9Sec
Cell standby = 7% with 16H 58M 44Sec
Phone idle = 4% with 11H 58M 34Sec
Android System = 3% with 42M 30Sec on CPU Usage and just 20Sec on CPU foreground
batt did last a full day for me i guess ending @ 6% when i got home
but what use is trying to save the batt life when i hardly use the phone
lets say i browsed the net for a 30min-1hour session, watched a few youtube video's/even downloaded video's for that matter or played a game or 2 for like 30 mins to an hour
ofcourse the display will be the major batt sucker by doing this and i doubt it would last an afternoon if i did so in the morning/noon time
I guess my only solution would be an extra batt or 2 for that matter if i really wanna show-off the phone and enjoy it fully for a full day. But the problem would be charging them all without a phone stand with extra batt charger
Anyways, does the batt last a full day for me , yes it does
am i satisfied doing what i did to make the batt last , N O

I got sick of my battery running out at around 3pm at work every day so I've now bought 2 extra batteries and an external charger from spider-foot.com

Well, greetings to all.
I just wanted to share my experience regarding the battery issue.
As I purchased the phone some 12 days ago, my experience is short, but somewhat effective.
First couple of days the battery lasted for app. 24h, with lots of usage (wi-fi surfing, lots of applications installation, calls, games, music, etc.). Then, I installed some "battery-indicator-related app", fully charged battery and used the phone for 15 minutes or so and went to sleep. In the morning my battery was at 80% !(it was on stand-by the whole night), and till 2pm it was at 15%, without using the phone at all.
Battery usage stated 64% "cell standby". I thought - what the .... ?
Than I did the next thing.
Uninstalled that crappy app, installed another one (similar, but other manufacturer),turned off the phone, fully charged it, turned it on, checked that wi-fi and BT are off, turned off 3G and syncs and updates, set brightness to lowest, installed black wallpaper, used task killer to kill all unwanted apps, and decided to see for how long will battery last with that settings and very little usage (couple of calls, sms and some sudoku playing).
The result:
4 days, 18 hours - since unplugged. Battery at 39%.

@ some of your replies
overflashing - ive only flashed once.
be lucky it only drops 6% when totally idle - the whole point in writing this thread was because ive previous lost 0%! when idle for hours and hours...
I have background data off (which i dont want to have to do) i have an APN switch which i use sometimes, but tbh its tedious and i shouldnt have to do this.
as far as im concerned, when i idle the phone, it shouldnt do ANYTHING

[Q] Apex 5.2 Rapid Battery Death

Over the past few weeks, I've been running Apex 5.2. I love it. The phone is faster than ever and my test show a 129% increase in battery life. That's why this afternoon's events took me off guard.
After sending a series of text messages, I left my phone on my desk for 39 minutes, silenced. The batter registered 43% when I put it down. When I returned, the battery had dropped to 6% and the phone had jumped from the norm of 89 degrees F to 116. I checked the apps to see what was running;
gTabSiMiClock
ChompSMS Notifications/Backlight single, three second power-up/Basic, single vibration)
Tag Launcher 2.2
Facebook (Notifications/No backlight/No vibrations)
Gmail (No notifications/No backlight/No vibrations)
This is the first time this has happened. I doubt these apps have the power to suck down that much battery life in that amount of time, as I have been using most of them on a daily basis. The only change I have made is the background (Image/not live).
Am I wrong, or should I be looking for other problems elsewhere?

Well I can't tell you exactly what the problem is, but I have had instances where my battery heated up a lot. Usually a reboot will keep it under control. That is a very alarming battery drain, though.

Have you checked for the 50% battery thing?

50% battery thing???
@OP not sure what happened buddy as this is a instance which cannot even be reproduced, coz as u said battery was better all the time barring this instance. However to get maximum support u may want to report all ur problems in the ROM thread..

The 50% time without signal. From multiple articles on xda, it's not rom related, it's an android problem.

TMO NEXUS 6 Battery life since newest update

My device is unrooted
Everything was going great until the newest update that came last week. Since this my battery life has gone down hill fast. I feel like I'm back on my G1.
I have two questions is anyone else having this issue at all?
My other question is all my previous phones have had SD card spots so when I reset myphone all my pictures are stored there. If I reset myphone do I lose all my pictures?

Battery life has been good for me on that build and the recent fi build as well. Do you have a secondary battery meter like better battery stats? There is no sd card in the phone so yes that would be lost.

of course you can check why your battery times have dropped.. like maybe a stuck process or a certain app draining battery. im nearly 100% sure its not because of the update, but it can be user related. your signal quality could be worse as well, which will also drain battery faster.

why not use an auto photo backup app like picasa or similar?

When I feel my phone getting hot or I notice the drain is going on I turn off my phone let it set to cool down or I just straight up restart it.
I live a pretty routine based life, Work, Church, Gym, Home.... So my signal life hasn't changed. My usage hasn't gone up or down....but my battery has since that update.
I do have battery apps to keep an eye on things. Display is number (of course) and number 2 which isn't normal is Android OS.

well, what ive found out iver the years that im with android is that battery apps are pointless, and end up using your battery. just check you regular battery usage/stats. nobody uses their phones the exact same way every single time, its impossible. and when you are out, walking around, or driving, your signal quality will change, constantly. and apps, many times they will get a process stuck, and drain much more battery than normal. and then there is google play services, that will occasionally drain lits of battery, especially when its updating itself. in reality, there are numerous other reasons, besides the update, that will make you battery drain quicker. too numerous to list, lol.

my battery also has been going deep underground after last security update! nothing changed in the usage or the number of apps that i keep installed, so the suspect that the drain depends on the update in my opinion is becoming more and more real.
i also keep checking battery's stats and there isn't any anomaly or discrepancy compared to pre-update's stats.

I am in the same boat. I was using about 2-3 percent an hour before the security patch. But since the patch dropped I've been averaging about 10 percent an hour. I have to recharge at least once in the middle of the day. None of my apps changed.

Same here, noticeable difference in battery performance since last weeks update. Only change to apps is I am now using Google fit since last week, thought it was that but battery stats say otherwise.

So last night I backed up all my pictures on my computer and the cloud. Tonight I will reset my phone before bed Ill have a better idea of what it will do tomorrow. It kinda stinks because I have this zooper/launchy/popup widget masterpiece going on my homescreen
Ill report back....

I have noticed the same issue since the OTA patch. Reminded me of my old Galaxy S where it would not go into deep sleep after being unplugged at a full charge without a reboot. I've gone without a reboot and with rebooting since the update and my phone is much better off after a reboot. About 7% per hour lost without compared to about 3-4% per hour lost with a reboot. Pretty consistent usage on a daily basis. Just my personal observation. I'm on AT&T though.

I got better battery life after the update... But then it went back to normal. I was being about 30 to 45 minutes extra SOT but now I'm back to my average times of 4-4:15 hours

Take this for what it is.... I wake up at 545 grab my phone since the update by the time I get to work 7am it would be 96 or below.... I reset my phone last night and the phone seems back to normal at 99%-98%when I sit at my desk..... All apps reloaded and working before bed.....

My N6 is worse off for battery too after OTA update of last week. Seems like Google Services has just gotten a lot more aggressive doing what it is supposed to be doing. I hope Marshmallow will fix this.

Well, mine also loses a lot per hr...and it alsways is the cell interface that is being kept awake over hours of time during a day.
Mainly email and Google services are the apps sucking it off...
Any ideas?

Factory reset and back to normal so far.

Massive battery drain before and after wipe

Hi. Can someone help me with my problem?
Im facing massive battery drain even after wipe, im only getting around 3/4h SOT. In BBS, 2 alarms are weird Job.delay. And job.deadline. I have wiped my phone, installed last version of rom, after that i have restored my apps. Problem still exist. Next i have installed kirasakura kernel and then frozen every of my apps, and its still there. After night im losing around 10/20% of battery. Im attaching some screens from bbs. Thanks in advance for every help.

i'll try to help as much as i can. install servicely and look at running services. if you see something weird, stop that service.
also, i see you're using bluetooth. that thing drained my battery as bluetooth would stay turned on even when it says it's off. what you can do is turn it on and off and it should stop bluetooth service from running.
in servicely you can disable apps from running in the background. maybe some app is running full throttle even tho you thought you closed it.
another thing you can check is if xmode is running. once i had system turning on xmode on even tho i closed the app that used it.
as you're rooted, check with some kernel manager what cpu governor is turned on. maybe the system is stuck in performance mode.
lastly, you can check your battery capacity. maybe it needs calibration. that could also result in battery drain as it's not charged to the max.
also, android 10 is generaly badly optimised for our phone. it has some good features, but powerwise it's not that efficient.
if nothing works out, i'd suggest returning to latest android 9 and do battery calibration.

Thanks for answer. I have installed servicely but im not see anything suspicious. Xmode is off, governor ist in performance mode. About battery calibration, i dont need extra juice from my battery, i want to lose 1% over night, not 20%.. Probably around July/august everything was fine, my battery last for almost 3 days, now something eating it alive and i dont know what is it. Can i somehow check which app generate this "job" alarms? In BBS its "Android" only..

battery calibration isn't about extra juice, it's about system showing the right percentage. you could lose a lot of battery because it doesn't get charged to its max capacity.
there could also be a problem with the lastest update. when i was seeing a lot of battery drain, i had it because system constantly used location services. check in services if there are any location processes running. also it could be because of network. maybe your phone is constantly switching between 3g and 4g.
you can also check in the kernel manager what is your current battery draw in mAh. if its always over 300mAh, then you have a problem.
look for a wakelocks running in the background and disable and enable some to get them resetted.

Probably u have solved my problem. Even after turning off location, i still have some running services with location in name. I have blocked all of them in servicely and after night i lost 1% of battery. I will check now in later days. Thanks a lot

A reload generally solves nothing and wastes time. It's always best to find the root cause(s) and address them directly otherwise they tend to reoccur.
Viruses (never had to), boot loops (prey it works) and old loads are the only times I reload.

yeah i thought it could be that. it's also worth checking if you have "find my phone" turned on. it's somewhere in the settings. search for device admin apps. if you see any apps turned on as device administrators, turn that off. those could also drain battery

Yep, i have turned off "find my phone" now. Thanks once again. Now i have nearly 8h SoT again. I hope it will be all good now

i'd still do battery calibration if i were you. 8 hours of sot is not that much. i mean, it is if you're playing games all the time

After couple of days, problem is back. No new apps, 3 days was good, 0/1% drain in night, now its again about 15/20%. I will just sell this phone becouse i dont have any more patience...6000mah and my OP3 with half of that value can ez get about 5h sot. Aktually im getting about 3/4h sot and 3h calls. When i have bought this phone i have had about 10 h SOT and 5 h of calls in 3 days of usage. Never again gonna buy phone from asus. Thanks guys for every help

i wouldn't condemn the whole brand because of one phone model.
also try going back to android 9 and check how's the battery drain without any apps installed. then start installing your apps and monitoring if the drain will increase.
i'm currently on android 10 and there is some major problem with battery regulation. raw capacity goes below zero when the percentage is below 10 percent. no wonder the whole system starts stuttering when battery level is below 3%.
