Hi All
just for discussion to know if 5% of the battery time is used by Tablet Idle when the tab is sleeping is normal and it's what every one have.
thanks

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!
I have Problem With Standby Time .....My Battery After 12 Hours Standby Have 50% Drop.....I install Stock Rom But Itsnt Fix...Please Help Me:crying:
( I do wipe cash and wipe battey and calibrate)

how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.
First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection

Deep Sleep Battery Saver
All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.
Since last couple of days I am facing a strange issue ...
Usually while I sleep I am used to checking how much battery is still there ...e.g if the battery is say 95% full at night the next day it becomes at the most 93% (phone in the idle state) !!!
Now comes my problem , since a couple of days i have noticed that the battery is going down by about 7 to 8% in idle state , then i checked the battery consumption in the phone settings & to my surprise I saw "Android OS" taking 56% of battery in idle state & that means something is continuosly running in the background eating up my precious battery...What the hell can it be ??
I have not installed any indifferent app recently ...
Hi
Brand new phone here, not rooted and fully stock.
During last three days I noticed a huge battery drain overnight, so I installed Better Battery Stats. Being not rooted I don't see many info but one thing is clear: after 6h being idle, I have lost 17% and BBS shows one single line as per attached screenshot.
Any idea what's going on?
Thanks
try turning off wifi and anything that syncs constantly. go into settings, battery and see what it shows. no need for an extra app.
????
I don't want to turn off wifi at night.
With my edge+ all was remaining on and I would use only 4% overnight
I have the same problem. Go to sleep at night and wake up 7 hours later with 40% drain during the night. I don't use wifi.

I've had this phone for a week, and the first 3 days all was ok, but during the last 3 nights I am experiencing this huge drain overnight.
Problem is I am not rooted (and am not willing to root right now, till Android N comes) so I cannot really use wakelock detectors to see what's going on.
Phone is set up exactly like my Samsung S6 Edge+ and this one drain max 5% overnight.
Again go into settings and battery and see what is being used
Ok tonight I'll check
Here it is.
Unplugged and left 6h idle overnight with wifi on.
Lost 12℅
I cannot understand what's going on

Please note this happens only at night while phone is idle.
During day battery seems OK and wifi or idle do not show up in battery usage.
Also from the screenshot I see only 1% and a very low mA usage, so I don't understand why I lose so much battery when nothing is going on.
Is this really a problem? Your phone is losing between 2% and 3.3% per hour. That doesn't seem that bad. Mine is around 6% during the day (I have it plugged in during the night).
2% per hour in doze at night is a huge problem

Yeah, that kind of drain is an issue. I lose like 1% every 6 or 7 hours overnight with phone in doze with 2 maint. cycles
hey i not use my phone about 15h i go to sleep and i woke up i see 92% from 100% . wifi and BT and GPS and SYNCH turn off. i all turned off. so why battery about 15hours of stand-by discharging 8%?
Because also standby uses energy. Phone is switched on, searching for net, doing scheduled jobs, some apps search for updates...
So, 8% in 15 hours is 0.5% per hour. I think that this is a good rate.

but i switched off everything so how searching for net or apps search updeates?
Because searching for consumes energy. You have a machine switched on, this consumes energy. If a machine does not consume energy, then ¿why it needs battery/plug? Unplug it and you have an eternal machine working forever.
