After standby about 10 hours, my HD2's battery decreases from 100% to 71%.
Is this normal? Or I should get a battery replacement?
I'm using the 1.48 WWE ROM.
There's already a thread discussing that exact thing...
http://forum.xda-developers.com/showthread.php?t=607873
Join in there.
with a bit of research in these forums you can find your answer and ways to make your battery last longer...
mine lasts more than 2.5 days with a single charge and normal use.
i have disabled 3G and data connections -when i dont need them- and i use flight mode during the night..
oh! and as johncmolyneux said, a bit of search never harmed anyone eh?!
Thanks for the information.
djngal,
What is ROM you're using? I always disable data connections when not use, turn on Power Saving. But overnight the battery is drained 30% .
And are you using G-Alarm? I doubt that G-Alarm causes this problem.

im using the stock 1.48 WWE and im also using g-alarm because it helps to put the phone out of flight mode in the morning and its also a great alarm compared to the buggy win alarm
during the night with flight mode on, mine consumes around 5% of the battery. i would suggest to try for a couple of days to use nodata app that it can be found on this forum, leave the phone on 2G so virtually using it only for calls as u would use a non smartphone ( ) and see how battery holds on. it should hold for 2 days with minimal settings like that...
i suspect that your reception might not be good at your home and the phone struggles to hold a 3G data connection therefore draining your battery..
if everything else fails, hard reset, leave the phone for a few days without any software installed and inspect the battery..
for me, a problematic battery would be the last place i would look...
i also think there are some apps that you can monitor your battery usage and which apps are consuming it, although i have never used it so i cant help u further with that...
good luck with troubleshooting and dont panic

Many thanks for the suggestions, much appreciative.
So I think G-Alarm has nothing to to with the battery life in this case.
I'm using NoData, and I always use 2G because in my country 3G is not fully supported. I'll try to turn on Flight mode.

Haaa! I´d like to have your problem with 3g In my hometown theres only 3g.. can´t change to 2g..
i use WiFi @ home and work, 3G everywhere else.
my battery was over 50% before bed, woke up with am with 5% left.....
so 45% of my battery life was eaten up in 8 hours with NO use?
any thoughts?
Wifi seems to be a real battery eater on this device (along with GPS). I leave it switched off unless I'm actively using it, and have no problems with battery life (it would last >24 hours if I let it.. I charge overnight though).
As there's no 3G switch on the widget I don't ever switch that off so haven't seen what improvement that would give. Cell Standby is still the largest user of battery, so maybe it would.
Set wifi to sleep when screen turns off.
There's an option for that? Not seen that one..

I didn't know you could do that, however, i already have that option selected....after i found it in the menu.
i guess i'll just have to experiment and see if 3G saves me power over the weekend.
Yeah I am pretty sure that option is the default. It still definitely drains more power with the WiFi enabled than without, sleeping or not. Not sure vs 3g, I disable or enable both as I need them.
I thought Wifi drains very little power ... with my phone on airplane mode and wifi only, the battery lasts over 30 hours with Meebo on, push e-mail on, and e-mail sync every 15 min.
Likewise, I have gps/wifi/2g/screen widgets on my main home page.
This doesn't exactly apply to the OP, but there's a nice app called "Y5 - Battery" in the market that switches off the WiFi radio in areas that you usually don't use WiFi.
Also, you can see what's draining your battery if you go to Settings > About Phone > Battery Use. There's some cool graphs showing where all your battery went since the last charge. Maybe you have a program that's running in the background that's sucking up all your battery.
I have had some battery drain issues since I received my N1 3 days ago. I found that Android 2.1 has a nice battery log (/d/battery_log) which updates every 50 - 55 seconds. In doing some tests to see what was killing my battery I can tell you that it isn't WiFi.
I would say that when in use, 3G draws a bit more than WiFi when actively used, but when WiFi is just idle it seems better than when 3G is connected and not in use.
In case anyone cares...I am still isolating all of the battery drain issues, but one of the biggest I have eliminated by uninstalling seems to be from BeautifulWidgets. I found it hard to believe, but my testing seems pretty clear. I also have a decent draw whenever I'm in the car with Bluetooth sync going. I would have had a hard time confirming this without this battery log file.
Wifi is extremely power efficient on this device.
I use the device on at&t edge and have the wifi turned on all day. the battery drain with pus email i about 4%/hour.
I think the combination of wifi PLUS being on an HSDPA network is killing your battery.
pus email? sounds gross
A quick calculation gives me 2.4% an hour, and that's with sync on, Wifi off, 3G on and using the phone a bit (not so much today). That's consistent with what I see normally - if you never actually used the phone you could push 3 days out of it.. but of course there wouldn't be much point in having it switched on then so it drops to about a day after a bit of driving w/bluetooth on, streaming music, etc.
Of course it's not really productive to look at battery life as 'how long can I make this last' (although knowing I can theoretically push it to 3 days plus is going to be useful on holiday). You work out your average day.. say up at 8am, turn in at midnight, so that's 16 hours actual time that it's needed (assuming you charge overnight like most do) - then fiddle with the settings based on your own use so you hit that comfortably. I'm probably being overconservative right now.. I'm finishing the day with nearly 50% battery left & need to ramp it up a bit Maybe a few more games of Frozen Bubble..

I'd love to see someone get 12 days of standby!
The specs for mobile phones are always a bit of a fiction.. maybe you could do that if you put it in airplane mode and if you never activated the display at all...
I had a Sony Erricson that claimed 800 hours (over a month!) of Standby. Never got it over 2 days..
Would be interesting to see if anyone has managed 10 hours or even 7 hours of talk time... personally I doubt it.

Some phones in Airplane Mode when not used can do those kind of numbers though. My K800 lasted about 2 weeks in standby when running like above. Though that just proves how pointless such numbers are.
So when using wifi, is 3g auto turned off?

I would assume the data aspect is, but the 3G voice is still active, even with WiFi on.
My battery life was amazing when i bought the phone lasted like 2 days
Recently I got an update of less than 150mb after that my battery life is now horrible in normal mode it lasts 9 hours the screenshot i attached show my phones battery usage on POWER SAVING mode (50% used on power saving mode in 9hrs at NIGHT when i don't use the phone)
and rite now i'm charging the phone again dont know whats wrong with it.
(It doesn't overheat or anything just loses battery.)
Will appreciate if someone can help troubleshoot this issue.

First of allI would say that your active GPS is a high battery drain so I would turn it of and see again if the battery drain is still that high.
Thnx turned off GPS and restarted phone now it's fine 85% from 100% in five hours with moderate use.
So is my GPS app is faulty?
I use maps a lot so how do I keep my GPS on but without this issue, my GPS was on from purchasing time but nothing like this happened.
Hoping for a permanent fix.
Once again appreciate the prompt help.

it's hard to answer your question without any other details. do you use any widgets? any apps that might cause waking of the device? use apps that could show the wakelocks during deep sleep
I use the s health, the clock and calender and the track id however I went back to the store even after reset the issue was there They said I can change the fone but didn't have the black color ( white to me looks tacky) so I got the m8 instead. Thnx for the help.

change location service mode to power saving when not using maps, change to gps only when you need. Turn off bluetooth and wifi tethering. Switch to HSPA when you're using map because you don't need lte speed.
As the title says, standby battery is awful.
I have all the bloatware disabled, only things on push are gmail and facebook messenger.
Cell standby is also sitting at 20% battery usage, no matter what, 2nd on the list behind screen time. Note 3 had exactly the same issue where cell standby is concerned. None of my other phones have had this issue, including my S2 with buggy as hell CM11, OnePlus One, Moto G LTE, etc.
No matter what I do, even with everything disabled and on airplane mode, there's a constant 1% battery drain every hour.
In my Note 3's case, this only happened on stock samsung firmware. When I flashed CM11, the issue went away completely. Something like 0.3% drained per hour instead.
So to me the issue is with Samsung's crappy software. I know the battery life was woeful on the Note 4 anyway before an update came in to fix things up a bit. Maybe they're saving the fixes for 5.0?
I know a new update for the N910C was released a couple of days ago too, but not available on European models yet.
Anyone else having these issues?
I dont have this issue at all my friend if i were u id try a complete wipe 1st, some people have had this issue too so returning could be an answer
Same here...
I only lost 4% battery overnight and don't have this problem too
20% battery loss on standby but mobile data was enabled.
^ you may have a bad app and/or bad signal
I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.
Ignore the time its been on, the same thing happens during a day of heavy usage when in standby, same level of drain constantly.
1%+ may not seem that much to a lot of people, but with my usage i should get through 2 days regardless. It should be less than half of what it is. From the curent reporting in the battery stats, im losing almost 50% of my battery in standby over a day and a half or so.

The only things enabled for sync right now are the basic google apps such as chrome, calendar etc. They rarely sync though, and no other phone I've used in the last 2 years has had an issue with them.
Samsung sync constantly returns errors so I leave that off.
Last thing I'll be trying tonight is a full wipe without disabling any built in apps. Its doubtful, but maybe one of the core shamsung apps are trying to communicate with a disabled app or something. I really don't know.

Any update?
My n910c is terrible too. 15% battery loss in 3 hours of standby alone! Wtf! Tried every battery saving trick' no location on etc...
i would suggest u do few thing while u get on bed next time,
Full charge your phone and unplug before you on bed,
1. Restart the phone while on charging,after restart go to home screen and lock the screen and unplug then go to sleep,check it at the next morning u wake.
2.Left the phone with your daily apps running,full charge and unplug then go to sleep,check it at the next morning too when u wake.
this is how i solve those apps running not right.
like the screenshot below,
An apps running at night drained 30% battery within 6hours & 30mins & without switch on the screen or touch anything since i'm asleep *with wifi on*
2nd screen shot shown that cm browser running and consume 94% of processing among 30% battery
while cpu only running 20mins since i had weather & sync on during night.
After that i report to cm team and they send me latest version,
after re-install my phone just back to normal.
now my N910c note 4 is consuming 1% every 1.5hours standby with wifi/3g connected *my area 4g only 1~2 bar so i changed to 3G*
average daily usage were 4.5~5.5 hours screen on time with social apps,browsing infomation,checking e-mail every 1or2 hours,reading news with flipboard,news app,drawing something,watch some youtube video & with auto brightness but indoor most of the time.
hope this would help you

I did a full wipe, installed ANK5 update, unplugged at 10pm at 100%, woke up at 7am with 97%. This is what it should ALWAYS be.
However, after the 2nd charge after the full wipe, it's back to what it was, if not worse. Last night I unplugged at 11pm, woke up at 7am with 92% left. That's bang on 1% an hour again.
There is nothing keeping the device awake at all. It's very frustrating.
I can only assume Cell Standby is so high due to the fact that the phone isn't actually doing anything while the screen is off. After a 20hr day with only 1 hour SoT it's sitting at 72% battery left, with cell standby at 31%, just above Device Idle at 29%. It's a mystery to say the least.

Thanks for your post. I'll definitely try restarting etc again beforehand. I'm also considering another wipe, as S-Voice being disabled seems to cause quite a few errors in the camera app. The battery drain increased after I opened the camera app too, even after force closing etc. That could just be coincidence though.
1% every 1.5 hours still seems like a lot to me, but it seems like you have a lot more apps and things running, so it's actually very good!
Very tempted to just root the thing now and throw on a debloated OS and custom kernel.
Last night i go sleep with 10% of battery left, ( im not force closing any application at all - just exit ) when i wake up ( about 7 hours of sleeping ) phone was showing 8%
No data/wifi/gps etc. If you are not using mobile internet, switch to GSM! It takes more than 30% less battery power than 3G
I'm thinking this is a hardware fault of some sort. Maybe battery, I'm gonna replace and see cause tried from full charge placing it in airplane mode to see if signal was causing the problem, didn't touch it, screen off whole time for 2 hours. Upon looking at it I saw I'd lost 7% battery! Omg! In airplane mode?! In 2 hours?! In standby?!!
In normal use there are no Rouge apps or strange readings in battery stats at all. May be hardware fault.
I've had the N910K exynos, 6 hours plus sot battery life
I've had the N910F snapdragon, 6 hours plus sot battery life
This n910c give me 3 hours sot. I'm pissed lol. Right off!!
Thats really weird, it can be issue of the battery. My 910C has about 8/9 hours of SOT ( wifi only ).

Your mobile signal is very poor. I believe you have full bars but your screenshot ... well it shows us that your reception is poor. It may be one of the causes for your fast drain...

My SoT is fine if im only using it during 1 day. Its usually close to 6 hours. But its not heavy usage, just browsing mainly.
Let me know how the battery change goes. Im likely going to order a spare anyway for when im away from home, so will also report back.

At work its pretty poor, usually a bar or two on lte, but no other phone ive had has displayed battery drain like this in standby.
That still doesnt explain why it drains 1%/hr with nothing happening at home though with 4 bar lte and full wifi signal.
Ive also noticed voice calls are taking up significant battery. A 3min call used more battery than 20 mons of screen time at half brightness apparently, unless thats normal.
If its normal, then to me the cause seems to be battery related. If not, then faulty cellular chip.
Also heres some more screenshots.
This is over the course of the day with barely any usage.
The chunks where its awake, that's just when I'm playing music, not a rogue app.
Note the big standby drop at the start, then the standby drop later, both completely different amounts of drainage, yet both when doing nothing.
And there's nothing I can do about it. I only have a gear s2 connected at all times and wifi and mobile data off whenever possible. Before I leave to the gym battery is at 44%. After the car ride there it drops one percent. I unlock the phone, connect my powerbeats, and open youtube and there go another 5%. After a YouTube video there is 7% drain. About a 10 minute video too. Leaving the gym and hour later and I see a maybe 20% battery loss. I don't know how people with regular S7s get 4-5 hours SOT because I get only 3.5 maximum. I bought the edge looking for better battery life but it's practically no different than my S5. If anyone knows a magic trick to this, I need to know now because this is extremely annoying.
IF you got the device from an official retailer, just return and get a new replacement. Losing 7% watching a 10' video is not right even with max brightness. You can fix the standby drain by using Forcedoze (which helped reduce my standby drain by 50% to about 1% every 2 hours). 3.5 hours SOT is terrible even with max brightness. Just get a replacement please. It's not worth the time and frustration.
IF you don't have the option of getting a replacement. Forcedoze can help with the standby drain. Factory reset, set up normally (personally, I just turn off bluetooth NFC location and turn them on when needed), and hope that your terrible screen on time is software related.

Do you think it might be my location by any chance? Maybe the service in my area causes this drain. I also have gps on because of my gear s2 but I can turn that off and see what happens. GSAM tells me the in the past 30 minutes the drain rate is 15% per hour. I browsed the Internet a bit and have been using it the whole time. I'll try to also do a full battery drain test on geekbench with full brightness and see what it tells me.

It's a good possibility. I have a fairly weak signal where I am most of the day and only get about 4-5 hours of SOT. I have all radios off except WiFi and data when needed. Still with my usage I only charge every 2 to 3 days. I don't get the drain like you do from watching youtube though.
My battery life also sucks. I barely use my phone during the day and it almost dead when I go to sleep. Most of the day I am connected to wifi between my work or home. My old htc m8 one could last 40 hours. I think part of the problem is because I do not have root on this phone. I kind of regret switching because I cannot get root. I cannot use applications to adjust cpu or control my wifi, data and to turn off apps from starting automatically. I think tonight I am going to try and calibrate my battery.
I had horrible battery life after taking the 2 OTAs. BetterBatteryStats would not report the device going into deep sleep at all and I was losing about 10% per hour on standby. I did a Factory Data Reset and all the problems cleared away. BBS is reporting deep sleep after about 5 minutes of the display going dark. I have Wifi, data, Bluetooth, and high-accuracy Location services turned on at all times. I lose about 2.5% per hour now with AOD turned on on standby.
Guess my advice would be to due a FDR after every OTA....
Guys, I had terrible battery life when I first got the phone. Off the charger at 6am, under 20% by 5pm... Follow my steps below and I bet your battery will do a 180 and be very nice. Mine gets me 35-40+ hours on a charge.
Disable the bloat apps you don't want in app manager.
Turn off Google usage and diagnostics reporting for the Google app, and if you use the Google keyboard, there too. This and the next one were the biggest improvements by far.
Turn off Samsung "Send Security Reports," and in the same place, turn off auto-update Samsung security updates.
Turn off device/Bluetooth/WiFi scanning.
Set keep WiFi on during sleep to while charging.
In permissions, I turned off location for any app I didn't think needed it. I went from 30+ to about 15. If an app requires location to work, you will get a popup warning when disabling location for it.
Lastly, I did a Restrict Background Data on several apps I didn't think needed it.
My phone started dozing and the battery drain dropped way out.
I keep AOD and Bluetooth on at all times and connected to my smartwatch all day, and my car about an hours a day.
Hope this helps! Apparently out of the box the S7/Edge battery life is terrible...

Turn off Google usage and diagnostics reporting for the Google app, and if you use the Google keyboard, there too. This and the next one were the biggest improvements by far.
Turn off Samsung "Send Security Reports," and in the same place, turn off auto-update Samsung security updates.
Turn off device/Bluetooth/WiFi scanning.
Set keep WiFi on during sleep to while charging.
In permissions, I turned off location for any app I didn't think needed it. I went from 30+ to about 15. If an app requires location to work, you will get a popup warning when disabling location for it.
Lastly, I did a Restrict Background Data on several apps I didn't think needed it.
My phone started dozing and the battery drain dropped way out.
I keep AOD and Bluetooth on at all times and connected to my smartwatch all day, and my car about an hours a day.
Hope this helps! Apparently out of the box the S7/Edge battery life is terrible...

I installed forcedoze and did the adb non-root command and now my phone's battery is holding up better. I think the phone was just sleeping.
It's ridiculous one has to do all this to get closer to acceptable battery life.
Google and SEC should be ashamed of themselves!
It's not just VZW devices either. AT&T are just as bad.
I've given up on trying to get acceptable standby drain and just let the device live on a wireless charger.

I had horrible battery life after taking the 2 OTAs. BetterBatteryStats would not report the device going into deep sleep at all and I was losing about 10% per hour on standby. I did a Factory Data Reset and all the problems cleared away. BBS is reporting deep sleep after about 5 minutes of the display going dark. I have Wifi, data, Bluetooth, and high-accuracy Location services turned on at all times. I lose about 2.5% per hour now with AOD turned on on standby.
Guess my advice would be to due a FDR after every OTA....

You need to turn off all radios when you go to sleep for the device to enter deep sleep. I had the same problem and when I started turning off wifi and mobile data for the night GSAM reported deep sleep and I was only losing 3% per night.

I keep all my radios on (BT, LTE, and WiFi) and BBS and GSAM Pro all report that my phone goes into Deep Sleep.
