[Q] Batt consumption after OTA update

Did anyone notice a change in battery consumption after the ota update?
Before the update I was getting to 97 percent after about 3 hours of the phone in idle - almost no use at all, no WiFi.
now It got to 94 percent with the same usage apart from 3 photos taken, could be that i'm just too harsh about it.. but still - wanted to check if anyone noticed anything.
edit: also I forgot to mention that I added the "mail" widget to one of the home screens, could be the power taker?

Probably the mail widget and the picture shooting (takes much ressources).
I haven't noticed any increased battery consumption, but it is probably to soon to tell.

Also forgot to mention I added two 'folder organizer' widgets , two folders which contain apps and games.
tomorrow I'll start off by removing them + the email widget and see if there is a difference.

are u really lookin' after for a 3% change in a 3h time ? maaan ... this could be a simple measure problem ... dont it take it too serious. if ya want to test it, maki it at least 10-20h run in standby (airplane mode on) ... it doesn't that accurate.

Yeh yeh I know I know I'm exaggerating.. I'm just becoming insane when it comes to battery life for some reason.. guess it's still the HD2's influence
It shouldn't bother me that much as it is.. I have a charger in my car plus I'm almost never gone more than 9 hours from home, which should be more than enough for the batt to last.. call me crazy it just occupies my mind

Update: strangest thing.... I just checked the phone, didnt turn the screen on since exactly one hour ago, batt was at 83 percent... that's about 9 percent in one hour!!!
removed the folder organizer folders, rebooted the phone, and suddenly received sms messages I should have received last night
now that's becoming something I should put my eye on.......

Update -
Well after another hour, phone only dropped 1 percent, i'll try to isolate the problem by adding the folder organizer widgets back and check in in one hour to see what the batt has to say..
If it'll drop 1-2 percent I guess there was some glitch causing the phone to not get calls\sms's and drop the batt usage about 10% in one hour..
Another thing I'm going to do is let it drain until it turns itself off and then fully charge it, I'v heard you should do that like 5 times when getting a new phone.

Update - 1 percent after another hour + folder organizer folders.. so, guess it was some major batt\radio glitch since last night until i rebooted today (phone was on charge all night)

I noticed that the setting 'Best WiFi performance' adds a serious battery drain when enabled after installing the FOTA, I was loosing 8-9% an hour compared to 3-4% before the update. Disabling this brought me back to 2-3% an hour. I still have a way better WiFi-connectivity compared to before the FOTA with this setting disabled.

I actually never checked that option but yeh I get your point, all is ok now I'll update if anything weird will happen, i'm getting 1-2% an hour

I charged mine up the night before last and have used it for internet, Angry Birds, whilst waiting for my clients and a lot of texting and about 10 mins of calls. This morning It's at 60% as I post this. I've noticed a huge difference since the upgrade and the phone is nowhere near as hot since the upgrade either.

It was a glitch 100%..
yesterday I let the phone drain itself (1day 7 hours - after the incident with the battery gone down 20 percent in 2 hours) then I fully charged it, turned it on last night before went to sleep, phone has been on since last night approx' 12 hours now - gone to 97 percent!! this is awesome!! I'm gonna' let it drain again a couple more times and this all over again

Battery lasts for approx 11-13 hours. Loosing 8-10% each hour with no usage at all.
It is updated. Reset to factory defaults. No extra apps installed. Just gmail, htc hub sync, wifi and that kind of stuff. No friends stream or Facebook or twitter.
What should I do? This is totally unacceptable.
Anyone tried to send it to service for fix?

first of all let the battery drain itself and let the phone shut down on its own, then fully charge the battery while the phone is off, do this for 3-4 times it will increase the battery's life span and charge time.
also check for the "best WIFI performance" as described in my post above, if it's checked uncheck it.
use auto screen brightness.
most important of all and may be causing your issue - check the stats of your charger, the charger I got with my sensation is imho faulty, it makes electricity noises, so I went back to my old HD2 one - perfect - the most important thing to check in your charger is the output voltages - it has to read 5v---1a - nothing different.

I think its better not to use auto screen brightness but use a fixed setting (maybe at around 25-30% brightness level). The reason being, the processor will have to be worked upon constantly to find the optimum brightness level and that would consume power!

Personally I believe the process of identifying the lighting and adapting to it doesn't take much effort from the processor, and based on my phone - the screen does consume energy but it will last 48 hours with the auto brightness setting on so why not use it? it's one of the good options we have in our phones and i really like it that when i go outside to the sun it'll increase the brightness in a millisecond.
the guy from the post above that's getting 10 hours of usage has a problem that I don't believe has something to do with his screen brightness unless he keeps the screen turned on all the time....

I updated to 1.35.xxx.x in the morning and after that the battery meter has only gone down by about 20% in the last 7 hours or so! The phone was off charge in the morning and I downloaded the update over my 2G connection. I also put on a live wallpaper just for fun! No calls made/received but few texts only. No games played. Surfed a little bit on internet (maybe 10 mins).
I'm liking it

Cell Standby Battery Drain

I've searched about a million times in 900 different threads, but I still can't find a fix to this issue.
I first noticed this when I flashed MIUI onto my phone. I would get cell standby and cell idle at about 40-50% of battery usage each. Display wouldn't even be shown on the usage! I then figured MIUI wasn't worth it to me, so I flashed CM7. I tried both morfic's and faux's many kernels, nothing seemed to fix the issue. If I would turn the airplane mode on, I'd get battery drain of only like 2%/hour.
So I figured there was something wrong with the CM7 port, so I tried g2xtreme and other GB ROMs, same thing. Finally, I just checked a froyo ROM, same thing again!
So at this point I'm clueless and thinking the phone is completely a POS, but anyways. I'm about to nandroid restore stock 2.2 firmware, and try updating through the LG Mobile Support Tool.
But I have my doubts that this will fix it. I'm curious though if maybe I'm getting this drain because I'm with WIND Mobile in Canada? And this is for the T-Mobile G2X (they're the same phone and both companies use the same radio frequencies). But maybe there's something written in these ROMs to tell the phone to look for the T-Mobile network? Which I obviously won't be able to find in Canada.
Can someone help me locate these settings, if they exist? Or can someone with a Wind phone maybe toss me the WIND stock firmware? Or let me know what ROM they're using without said issue?
Thanks guys!
Edit:: In low signal areas the phone drains like 15-20% per hour, in high signal areas the phone is still pulling like 8%-10% an hour and I'm not even using it! And the weird thing is it only shows 1% time without signal! Something is seriously wrong with this firmware.

Search for betterbatterystats on XDA, install it, enable battery monitoring in MIUI (if that's your daily rom), leave your phone alone for a few hours, then open BBS and look at the partial wakelocks under "since unplugged." There you'll see what's killing your battery.
Everyone experiences worse battery life when reception is bad, but you are still getting terrible drainage in good areas, which means there's something other than reception killing your battery.

I tried that before, and had a crapload of apps "frozen" with titanium backup.
I'm going to try this again, and I'll post a screenshot this time because I don't think I actually understood what betterbattery stats was trying to tell me last time.
If anyone can help me decode it later that would be great!

Just noticed that there's barely anything under partial wakelock that's noticeable.. RIJL Telephony is the highest with 1m 1s 15%.
But it's not increasing very much, only when I get a text message. However, I've dropped about 7% since my last message, and cell standby is increasing climbing up my battery usage from 33% to 42%. It went from 620uah to 657uah.
Edit:: I reset battery stats cause I was unsure if it was corrupted stats. I started at 17% 40 minutes later I'm at 12%. Phone was off 90% of the time. I made a 2.5 minute call and it used 41uah, while cell standby still dominated with 65uah.
However, I turned my phone on for 5 minutes, making total usage 45 minutes, but had the brightness set to max, and in that five minutes it only used 1uah.
Am I missing something here? At this point I don't know if my numbers are normal or not anymore... I'm going to try draining the battery, charging to full, wiping battery stats, and calibrating and see what happens but 65uah to 1uah is a huge difference, I would've thought display would use a bit more than that.

I noticed this morning that having the phone with airplane mode OFF, that my battery dropped 10% in 57 minutes, and after turning the airplane mode ON, the battery dropped 1% in the next hour and 30 minutes. I checked battery stats and nothing was waking up my phone. Anyone have any other suggestions?
I'm going to flash miui and leave it without any apps installed then try this experiment again.

I find these threads interesting because I am always looking for better battery life.
I am running EB 2.3.3
I uninstalled Set CPU and uninstalled Juice Defender. From my experience both hurt my battery life.
I never bothered to measure in airplane mode, because i use my phone to much.
My battery life improved dramatically during stand-by. 1% to 2% drop per hour with wifi on and a slightly bigger drop with wifi off.
I completely wiped the phone before installing EB and the used Titanium Backup to reinstall my apps without the data. I believe some of my previous battery life issues came from restoring data from certain apps.

I have the same phone/carrier. Do you leave 3G turned on? I feel it rapes my battery throughout the day. When I turned it off, it lasts pretty long.
Another problem I have though, is the drain when it is OFF. I went to bed with it at 90% juice and turned it off. I woke up 8 hours later, and it was at 65% when I turned it on. wtf. This only happens sometimes thou.. Other times it doesn't drop too much.

I experience the exact same issue. But for some reason my battery life is more or less the same with 3g off. So I feel like my phone is constantly searching for a different signal or something? I mean if airplane mode affects my battery life that drastically reducing consumption by like 9%/hour then there must be something up

Everyone who's been telling my phone is not sleeping is correct.
Only program is is that my phone's battery stats doesn't say which app is waking the phone? It lists Telephony as #1 with 1m 1s of awake time, and everything else is minuscule. There's gotta be something the phone isn't telling me :S Could it possibly be a hardware issue?
Or is there a better way I can narrow down this issue? I'm in the process of removing all apps.

Just curious, did you 'train' your battery?

Nope, but it's Li-Ion and my impression was these do not need to be trained.
I just emptied it to complete 0 yesterday, and charged it to complete 100% then calibrated it. Today though it was still horrible battery life until I completely wiped and flashed MIUI 1.9.23 then Trinity kernel brand new. I'm installing apps 1 by 1 to see which one caused me so much darn grief :S

All batteries are Li-ion nowadays, but I still feel after 'training' my battery for a week, they last substantially longer than new ones, fresh out the plastic.

Yes, battery drain is fixed. Also, I was on a completely different baseband for some reason, I was on the o2x baseband, fixed that JUST now, I think that was a part of the reason I was draining my battery like instantly. It was probably looking for a GSM signal!
Thank you for all your help

A simple *#*#4636#*#* can change that.

Yeah I set it to WCDMA Only. Battery life has been awesome lately.

I think I solved the ICS fast battery drain... simple solution

I have a Galaxy Note and updated to ICS about a month ago....
Like many of you I also experienced fast battery drain, around 10% or more per hour, without usage. even more when I use it. 5 hours with moderate usage.
I am on unlimited data plan so 4G is always on.
I also tried fully charging the phone before going to bed at 11pm, woke up at 6am and battery already at 20+%, that's when I was sleeping, no use at all.
For a month, I have been charging my phone 2x a day!
I was very frustrated and wanted to go back to GB.
I was researching for weeks for the solution (also, checking for ICS updates almost everyday, waiting to see if Android had found a solution already), no one seemed to have a concrete solution, some suggest resetting, formatting etc.
These were so complicated for me I didn't even dream of doing them.
3 days ago, I accidentally switched off my 4G connection.
I didn't realize that the connection was off..
I was happy to see my battery charge was still at 98% after an hour, after 2 hours, light usage 95%.
"What's happening?"
Then I saw that my 4G was off.
Now, I was thinking 4G connection was the culprit... but I wanted to explore more and see if there was an app that could be causing this....
I checked my apps that used data and nothing was on, then I checked my sync settings, This is where I found out that I had so many accounts that had SYNC ON! Twitter, facebook, gmail, samsung e-mail etc.
So, I tried an experiment.... I stopped SYNCING everything.
It worked!
For one day, maybe 12hrs. (light usage with 4G connection on, just light usage, I checked my gmail by using the refresh button) 75% left on the battery!!! Wow!!
Then I thought "come on...gmail and android? Same owner/company right? I'm going to try to turn ON the GMAIL SYNC, I'm sure there won't be a problem"
I was right!!!
Now on my second day with 4G connection ON, Sync Gmail ON, medium usage, maybe 20-30min of phone calls, 30 or more texts, email and around 10 minutes of internet surfing.
9 hours unplugged and battery only at 70%!!!
I am very happy!
Oh, last night, I think only about 8-10% of battery was used (6 or 7 hours of sleep only 8-10% used....) nice!
For those who have not tried it yet... please try it... I hope it also works for you.
I just wanted to share my experience and hopefully help others that are, i'm sure, also already so frustrated with ICS.
I apologize for the long post.
Cheers!

so in other words disabling sync for apps that use networks poorly, over a high power useage radio.
its not really a solution, more of avoiding the problem . I know sync falls under android os in the data usage. which means to disable its bg data disables it all, so the real solution is to apply bg data restrictions to sync list as well to cover all ways of data access.
evidence of this is that Facebook ignores bg data restrictions( no big surprise there)

I think there is something wrong with my twitter app?
maybe I changed my password in my home page but did not change it in my twitter app and the app kept on trying and trying to log in but can't, maybe this caused the fast battery drain?
I didn't check it yet, maybe one of these days, but now, I'm happy... I really don't need to sync twitter all the time anyway.
Guys, check your accounts and sync... let us know what happens.

OLD NEWS.

Try this. My experience is on the AT&T Skyrocket, but from the research I've done both the Skyrocket and Note have the same problem. It's probably your charger.

jrockttu said:
You have CPU Spy, so run this test to rule one thing out:
1) Charge your phone overnight.
2) When you wake up in the morning, pull it from the charger and reset the timers in CPU Spy.
3) Let the phone sit idle for a few minutes with the screen off.
4) Refresh the timers in CPU Spy.
If your phone spent significant time at 384 mhz during that idle time and none in Deep Sleep, it's your charger. If it's deep sleeping, it's not your charger (do you use more than one charger?) To further verify the problem, restart your phone, let it sit idle for a few minutes, and check CPU Spy to see if it went into deep sleep after you restarted.
I have a couple of chargers that cause my phone to never deep sleep after I charge with them. The thing that remedies it is restarting the phone or plugging in to a "working" charger. It's a know issue, there's a dedicated thread in the Note forum where someone pinpoints the issue for the Note.
I researched a lot about battery problems on this phone, so list more specifics (do you always use the same charger, charge to full, apps, widgets, etc) and I'd be glad to help. Also, when you take a screen shot of your battery life like you did, take one of your screen on time as well. Since that's your primary drain, it's a good indicator of how your battery life is. 8 hours of battery life sucks, but it's really good if 4 hours is with the screen on.
EDIT: Here's the link to a VERY informative thread on the issue for the Note: http://forum.xda-developers.com/show....php?t=1519084

wow.
the more stuff you have 'on' on your phone, the more battery it will use. hmmm. Do you leave GPS on when your inside a building also?

I think syncing should not be put on auto. Unless on necessary apps like email. And... email only? Facebook and what not social app, keeping track on website when you want to is prolly sufficient. Unnecessary background data mining will without doubt drain the battery.

I will PM all senior mods here on xda and suggest you for 'Elite Developer'...you deserved it like noone else

Terrible Battery Life

I don't know how everyone else is getting 3-5 hours of on screen time. When my screen is on, I lose about 1 percent every 2 minutes it seems like. When I look at the app usage, the kernel and media are sucking the life out of the battery. I am really discouraged about this battery because my G2 would easily get 3.5+ hours of on screen time. So far, I am going to be lucky to get about an hour.

Mine has terrible battery life
I am very much on the same page with you. I am on my 4th cycle.
Mine only last 14 hours with 3 hours of screen time. I don't understand how all these people are getting 5 to 6 hours of screen time.
I have both Better Battery Stat and GSam monitor and it shows Kernel is taking 50% and system is taking 6.2%

Just try with different kernals,good kernals would give exellent battery life

I would gladly take the battery problems to get rid of this brand new beast. It's too Frickin big.. I had g2 but sold it. Paid 700 for this att note 3...lol. straight talk on att towers to save on bills. But this thing may be the fastest latest greatest next to the new releases of '14 but I should have kept the g2...This is a tank. I'd swap for smaller phone in heartbeat. Might post cl ad

Are you in the right forum? This makes no sense.

I think it highly depends on what you're doing when screen is on. If you're playing games or using a lot of data, it can drain very quickly. If you're watching local videos or something, your battery would last a lot longer.

Im a beginner, xda said i must have 10 posts to do anything on xda so i was filling my posts..sorry friend....now i got 10 posts so im playing with n9005 rom section now

if you are rooted, install better battery stats (free on xda from the dev) to see the culprit.
clearly something is keeping the phone awake and hogging the cpu

So far today with only 10 minutes of screen on time and 45 minutes of playing a podcast through Bluetooth in my car the battery is down to 92%. This podcast was already downloaded and just playing from Dogcatcher. When I left I rebooted the phone right after pulling it off the charger. The phone is rooted and all Verizon apps are disabled. I see the android system at 40% and Google Services at 15% usage. Yesterday with only about 2 hours of screen on time I was down to 18% after 10 hours off the charger. I do not see any one app drawing power, it is always the android system it seems.
Edit: Using BetterbatteryStats I noticed that my phone has basically been awake the entire time it has been off the charger. Out of 2.5 hours it was in deep sleep for 10 minutes.

I don't get great battery life either. Nor do I get good game performance. Battery has went down 9% in less than 2 hours of idle. Just downloaded gsam the kernel use is the highest at 26+ percentage

Turning off Location Reporting made a HUGE difference to my battery life. I accidentally left my phone laying in bed next to me last night instead of plugged in, and it dropped maybe 5% over 6 hours.

I will try disabling location reporting. But I know with my Galaxy S3 I had this enabled and did not have battery issues.

I turned off location reporting and location history and am seeing better battery life today. 5hrs 47 min and 89% battery left.

My battery is confusing me. First 2 days.. 15hrs 3hrs screen on time.. 3 days after that 24+hrs with 5hrs screen on time... The past couple of days I'm back down to 14-15hrs with 1-3hrs screen on time. This is running it down to 10%
My usage isn't much different from day to day.
Power saving is now enabled and I turned off location settings. Let's see...
M8, nuff said.

What I do not understand is why my old GS3 and my co-workers HTC One M7 with location services on, do not have this battery drain problem. This should not be an issue.

Yeah, it seems to be an on and off issue. On my GNex sometimes after flashing a ROM I had to turn location reporting off to get through the day, and then after the next ROM flash I didn't.

Why do I have terrible battery life?

I just got my Z5 a few days ago, and the battery life is downright AWFUL. With stamina mode on, my phone drains about 1% every minute or two, just while browsing the web. What is going on here?
Here's a screenshot: http://i.imgur.com/uDv2hIs.png

Me too, it's a total letdown. Had 3 hours SOC and around 9-10 hours overall before it conked out on me yesterday

Looks like your device is spending a lot of time switching networks which is battery intensive. Are you in a poor signal area?

Try airplane mode and see if it improves. This will allow you to use WIFI but halt network search and switching. Check battery stats after a while to see if that helps. Of course, you will get no network dependent communications while in airplane mode so take that into consideration prior to testing. Battery performance will settle down after a few weeks as well but you certainly seem to have a major drain problem and testing will help you locate the cause.

All right, thanks. I'm gonna try that and report back here later today.

Okay, airplane mode hasn't helped much at all. I'm still draining 1% every minute or two.

That is truly strange. Any running apps killing it? I just streamed a two hour movie and lost 22%. I read somewhere that the pre-installed AVG was a battery hog. I couldn't tell you because I uninstalled it as soon as I booted for the first time. Are you still running it? That may be the next test.

Nope, I uninstalled it immediately too.

Only other suggestion is factory reset or repair firmware both if which are a PIA.

Yeah, I thought it would come to this.

Have you looked at your Google account settings to see if everything is syncing properly? I have seen this before when someone had an error while trying to sync photos to their Google account, demolished their battery until they went into account settings and unchecked whatever it was that was syncing constantly.
Also make sure you have opted out of Google's location history thing in Google maps where it tells you everywhere you've been on any given day, that can wipe your battery as well. Lastly try turning off the xperia protection that allows you to remotely deactivate the phone, just make sure you don't lose it in the meantime !

I got a Z5 the day it came out and it has done pretty well on battery life, at least until I installed Facebook and Messenger. When I uninstalled the two of them, the battery life returned to pretty good. With Facebook and Messenger the battery was draining extremely quickly. I unlocked the bootloader the day I got the phone and am waiting for TWRP as root will sort a lot of this out.

After 3 Days, i looks like a normale Day use by me around 50% battery. I have allthetime Bluetooth and Wlan on. Whatsapp and Gmail sync. I use my Phone usually for streamming musik over bluetooth around 2h hours, read news and message (Whatsapp) around 2h hours, play some games around 30minutes and some Calls around the same time. My "old" Z1 i had usually to charge ones during the day and of course during the night. So im happy with the battery time @ z5.

Okay, I just turned off automatic Google photos backup, and Google's location history setting was already off. I also turned off my Xperia (the thing that lets me remotely deactivate the phone). Let's see if it works.

Yeah, its still draining fast. In case you're wondering, I keep my screen at half brightness. You can look at the photo I attached.

Update?
Did you ever resolve the issue? I'm getting similar battery life and am not happy about it.

This may be a noob-ish suggestion and one that the phone industry claims isn't necessary anymore, but have you tried "calibrating" the battery by charging it to 100 and completely draining it to the point where the phone won't turn on 2 times and then fully charging it a 3rd time? It may be an old, unnecessary habit, but I've done this every time I get a new battery (or phone) and I usually have really good battery life for the first year - year and a half. The one device I failed to do this on was my Xperia z2 tablet and it suffered for it (i think) although that could just be my prejudice and confirmation bias speaking.

- others suggest NOT to fully drain your phone's battery because you might have troubles turning it on.

Did you by any chance have "Glove Mode" enabled in Settings < Display? It seems that your screen is the culprit. Try disabling "Smart backlight" if you have it enabled and "Tap to wake up".
From the screenshot you posted earlier (History details) we can see that even when the screen is off the wifi is on and the phone isn't actually sleeping. So you got a wakelock on your hands that uses WiFi and doesn't let the phone sleep.
In WiFi settings under advanced (Wifi< Three dots, top right< Advanced) do you have wifi as always on? Change it to "Only when plugged in", also disable "Scanning always available" in the same menu.
Any chance we can get a list of apps you have installed yourself on your phone?
