hi,
galaxy note 3 here with crash rom and rather good battery life - i'm a battery life junkie
actually I don't have a problem, i just want to understand something.
many people posting problems about mediaserver and mediascan draining their batteries. first of all i think many users dont undertsand that the 2 processes are different, but thats another story.
IN FACT, whenever i play may mp3s/Flacs with poweramp, my batterystats are showing a very high percentage of MEDIASERVER. after 3 hours of playing songs with screen OFF, the percentage is even higher than 4 hours of screentime with other apps! i was very afraid, but then i found out that the truth is, that 1 hour of audio playback with screen off, takes just 3% of battery. and even background playback with screen ON, takes just 10% of power per hour. thats quit good.
In the screenshots you can see 48% when starting playback, and after 1hour of playback with screen off, its at 45%.
in the BBS screen shot you can see that audioout2/mediaserver is keeping my device awake for the whole hour, which is somehow frightening, but maybe normal and as said, doesnt affect so much the battery life...
WHY is the percentage of mediaserver in the android batterystats THAT high than?
some may say its not a big deal and that i should be happy with my battery life. well, i AM, but i just want to understand....
Hi, I have FINALLY found a solution for the bug of mediaserver process with Poweramp. With the fade option enabled, mediaserver process starts when i change song while with crossfade option disabled the process stop.

I was wondering, if I constantly am killing running process and they are always reloading (voice input, settings, gmail, market, etc), will this drain my battery faster? I'm at 76% with light use from a full charge and the phones been unplugged for around 4 1/2 hours.
That seems normal. mine usually dies within 6 hours, with all settings off. i think i need a new one. under battery settings it says display used 67 % of my battery life and for display time on it says 28 minutes
I've got my display using 73% followed by live wallpaper with 6%.
I mean Display% being higher just means you were actively using your phone more... or you set your timeout too high.
I don't think the actual restarting of the apps uses more battery vs them just running in the background all the time. Unless for some reason they restart almost instantly and you are constantly mashing the kill all apps button then maybe?
As far as your phone dying in 6 hours, that does not sound right at all. Mine definitely goes quite a bit longer than 6 hours consistently. It is currently at 38% battery after 17 hours 24m, with display having used 46% with 55m24s on. Part of that was while it was full brightness when I was outside. I have been at work though so its largely been sitting on my desk. Even when I first got it and was playing with it a ton it went well over 6 hours on a charge.
Some people do seem to have problems with battery life and I can only assume there's a bunch of bad batteries out there, or they are really hammering it..
I used about 25% in 6 hours today from normal usage* and that's even after driving around for half an hour streaming last.fm over bluetooth via 3G.. Sync switched on, wifi off, twitdroid running in the background. The only special thing I have is the setcpu idle tweak.

Hi everyone. I had NAND installed on my HD2 now for about a month and a half. One of the things that I haven't seen on my phone is better battery life. This is the first phone I have with a data plan so I'm really not sure how much of the battery drains with data. Here is my daily routine. I charge my phone overnight, by 11am-12pm my phone is just about dead. I put it on the charger until about 4pm; usually it's fully charged by then. By the time 10pm comes around it's almost dead again. Doesn't seem like good battery life to me. Someone please let me know if I'm missing something.
Thank you all!
Depends on what you're doing with your hd2.
If you spend a lot of time on the internet with either wifi or 3g, then that drains battery pretty quickly, as with any device. Playing games or watching videos is the same thing, although to a hiigher extent with games. Keeping the phone screen on is also one way to drain battery quickly.
You should install current widget and monitor your standby times, etc. In standy by, your phone should be consuming 4~6 mA ideally.
If you want to monitor your battery usage, first download and install CurrentWidget, enable logging while the phone is on standby to see your standby usage.
Second, need to check battery usage on standby after a call, there are some kernels with a known bug that prevents the phone from going to sleep, consuming 60ma on standby.
Third, Do a battery calibration, it does help a lot if you have never calibrated your battery, android tend to mess up battery reading after a while of not being calibrated. There's a thread about in on forums, search for it, REALLY good info there.
Fourth! check out if you are in a zone with crappy 3G, if the phone has to turn 2g/3g off and on too often it drains battery like whoa.
Fifth, take note of max and min voltage readings with CurrentWidget, your battery might by wearing out (should be maxing at 4.2v and min around 3.3v - 3.6v depending on kernel).
Another thing, before your phone dies, check out battery usage on Settings, see if any program is eating your battery, and check out how long has your screen been on, and post it here
I've always had WAY better battery in Android, even SD, than WMo, MSN/push email killed battery in WMo in about 6 hours, without use, just standby. Android get up to 4 days in standby with Gtalk/Gmail/Exchange Mail, all on Push, along with weather and twitter. With hardcore usage, the battery last between 6 and 7 hours top (Screen on for 4-5 hours), while Gaming, it wont last more than 4 hours (CPU at 100%, Screen always on, GPU at 100%, Brightness 100%).
Normal usage (between 40 mins and 1 hour of Google Maps with GPS on, between 3 and 4 hours of music thru Bluetooth with my car, 10-15 mins talking, about 20-30 SMSs and quite a bit of Gtalk) it makes it thru the day, lasting about 12-14 hours.
Such a low battery life is probably cause your phone is not going to sleep, it should be at 2-5 mah on standby.
Hope it helps
I can play an hour of pokemon (gba rom), listen to pandora whenever im in the car, surf the net for an hour or two, and with a total constant usage of about 5 hours, and at the end of the day ill be left with 30% battery still.
If I don't use it often it will last 40 hours +.
Maybe try a different nand rom?
Im running hyperdroid nand
Zephyrot and kangpeter, Im jealous of your battery life. I'll try what was posted. Thanks for the replies!
Hi,
I started doing some battery tests today as I think my battery is draining faster than the quoted figures on this forum.
Please note the following, tests were carried out with Power saving ENABLED, 4g ENABLED, brightness on auto, wifi off, sync off, GPS off, bluetooth off, playing full screen and all the air gestures/eye tracking scroll off
Test 1 - from 100% battery charge
Play the movie Casino Royale (1080p) - roughly 145 minutes. Battery drop from 100% to 80% = -20%.
Average battery consumption of 1% for every 7.25 minutes played.
Next test was carried away straight after. Therefore perhaps the phone could still be hot causing the battery to drain faster.
Test 2 - from 79% battery charge
Play the movie Never Back Down (1080p) - roughly 113 minutes. Battery drop from 79% to 57% =-22%
Average battery consumption of 1% for every 5.13 minutes played.
The fluctuation of battery consumption was roughly 29% between the two tests. Between the two, average consumption of 6.19minutes per 1% consumption. Therefore anticipated playback time from a full charge is estimated at 10.3hr
This leads me to believe that either the battery "gauge" on the phone is either inaccurate or (more likely) my battery is somewhat faulty. Why else would the efficiency change so much? With my very limited knowledge, I can only come to the conclusion it is linked to the device's heat.
My questions:
A) Are these consumption figures in line with everyone else?
B) Why would the battery consumption fluctuate like this
C) My battery is way more efficient playing movies then it is listening to music while using whatsapp. Is this normal?
A) yes your battery is good if not better than some other's
B) on every phone i experinced the battery drops lower from 100% than it does from 75% and from 40% it really drops faster
C) because your using the internet which consumes a lot of battery
Your approach is flawed:
Don't start at 100% because it may say that but could be less as the battery is not kept charging once it's full. As a result it could be a couple of points below 100 and you wouldn't know. There was an article about this somewhere on this site.
Also, you must use the same video file to get the same result. Utilization and load depend mainly on bitrate and codec used, not the length and/or resolution in itself.
Cheers Ewok, quite new to this and didnt realise that a different video could have a different effect on the efficiency
Hey guys, I'm having some wakelock issues.
I run greenify on draining apps and have some unused apps/processes frozen, but still have these issues.
So my questions are:
1) Could my battery drain be wifi/3g related? sometime it seems so, sometimes not.
2) Are these immense amounts of wakelocks normal? Audiomix could possibly be because of broken mp3 songs, have them already checked but not deleted. but i didn't even listen to music on this battery cycle.
3) WLD seems to lack some processes. What could cause it to not display the missing ones?
I highly doubt you have an issue here. Your battery doesn't look to be draining much at all. You're at 1 day and 3 hours according to BBS, 1 day and 18 hours according to your phone, and your highest wake lock is less than 30 minutes. That looks like Media, probably from music. That's pretty damn good for 27 hours or more I'd say. There's this misconception that all wake locks are bad. That's not the case. Wake locks are going to happen. Its unavoidable. If you had a wake lock that was at 3 hours or more I'd worry. But you don't, so I don't think you have an issue. Just enjoy your phone.
Never said, that i think they are bad
I just wondered, because 3k+ is quite a high number and i didn't find something i could compare it too. So i didnt know if it was normal or not.
Battery life is ok, but not that great. On the posted cycle, screen on time was just around 2-3 hours. Im getting some drains here and there and havent been able to figure it out yet.
But thanks mate
Hi, I found a weird situation recently. When listening to music, if screen is turned off, it drains my battery about 30% per hour and my phone becomes very hot, specially around cameras. Top two in battery use details are music player and Android System(these two ratios are same). However, if sceen is kept on, it only drains 6~8% battery per hour. I tried different music players and got similar results, and HIFI on or off did not make a difference. I am confused.
My phone is rooted and background apps are controlled by Greenify.

I'd venture a guess that you have something that's launching in the background and keeping the phone awake with screen off, causing the higher battery drain

It's gotta be those damn background apps (•~•)
