I left my tablet in standby mode for 24 hours and got 8% battery depleted. This thing has a very big battery and all but why would it drain that much in 24 hours in standby mode. Thats 784 mAh, which is about 50% of phone batteries. All radios and everything is turned off. Can anyone else report back with their drainage details. Also putting it in airplane mode will decrease the battery usage drastically. So whats going on?
I find the tablet main default is the battery consumption in standby.
During the first few days i thought to get a refund, but I have the feeling it got better. Have you tried to put it in airplaine mode ? I have the impression it's helping "a little".
This is my current charge, pretty heavy usage reading a good book. Can't complain.

Actually I'm not worried about usage battery life but standby buttery life. And yes putting it in airplane mode makes the drainage reasonable but why is there a difference when all radios and receivers are off. Any ideas?

Did you disable the virus app?
I'm getting at least 3 days on one charge with typical internet, book reading and minimal gaming. This is a HUGE improvement over usage I got on A500.
Only problem I see with A510 is that it heats up like crazy

I just got my A510 a week ago, and currently experiencing battery drain issue while the tablet is idling as well. I have it on airplane mode and Wifi off. The last day or so, it can drain about 10% every 2 hours while idling (screen is off). Did you find a fix for it yet? I may try reflash the ROM again using the update.zip file I have downloaded.

0.5% for every hour is actually really good. When you think about it, that amounts to about 200 hours, which is over 8 days. I don't think it gets better than that.
Don't be fooled by manufacturer specs that claim ridiculous amounts of standby time because that is under very specific conditions. For example, "Airplane Mode", no apps installed, and zero(0) screen time.
EDIT: I just noticed you have it on Airplane mode. Do you have anything installed that could keep it awake? Such as a third party launcher or lock screen?

That really isn't bad at all... why don't you use the phone normally, start from a full charge and when it gets to 5% check your battery stats again.
I haven't seen an Atrix rom yet on which the phone goes to sleep properly.
But to be fair, it doesn't influence battery life all that much.
And yes, 0.5% per hour drain is about the best you can get with this phone.
Have you had any problems with that rom? Now that I see your stats, I think I might switch to it.
How do you know it dont go to deep sleep mode? Install CPU Spy, and it will tell how many hours the phone stays in each cpu state...
Im on gingermod and my phone drains like 5-7% in like 8 hours if its only in standby, without data/wifi on, but keeping phone signal on.
Atrix 4g
I'm running WETDREAM 1. 3.0 and FAUX 1.3ghz kernel. No wifi, no gps, average widgets active, active twitter, active google plus, 3 gmail accounts and constantly playing shadow8-gun....i average 8-10 hrs with medium to harsh usage.
Neutrino has to be one of the best ROM's I've ever experienced. It's well maintained and has a host of performance improvements. I've had some of the best battery life out of this rom.
The ICS alpha is going well but its a long way away from matching the maturity of Neutrino. The battery life right now is not great due to a "bluesleep" issue but its currently being looked at.
Whichever rom you choose, make sure you calibrate your battery after flashing!
I read a blog which suggested, when charging overnight, to turn the N10 off completely rather than just having it sleep. Is there any merit to this? Does it charge faster?

It does charge faster because the device isn't doing anything to drain the battery. Although overnight is often when devices update themselves so it's up to you if it is necessary as it should fully charge overnight.
I dont see a reason to turn off the tablet to charge, and my tablet never gets turned off. Because there was a user here saying we needed to turn off our tablets any time we werent going to use it within the next hour or two, I did some battery tests. This tablet (assuming you aren't running battery draining apps in the background) loses 1% of battery every 7~ days when idle. So thinking the tablet will somehow charge faster while it is off would be false as we really have negligible drain during idle time. That is unless you are syncing a large number of apps and have a ton of things updating in the background.
Currently my tablet has been on and hasnt charged in 16 and a half days. I have been really busy at work during the week and busy with my friends on the weekends, so I have really only used my tablet about an hour and a half during this charge cycle. So have so far lost only 2% battery from idle, and another 19% from the hour to hour and a half from the time I was playing a video game on the tablet. Assuming I dont use the tablet, I truly expect to be able to pick it up in another 2 weeks from now if I wanted and still be in the 70% range on battery life remaining.

And if you do have a lot of stuff syncing in the background, you still wouldn't want to turn the tablet off while charging since then the things you want to sync will need to sync when you're running off battery instead.
Yup, I agree with the posts above. The only way you could really slow down charging significantly would be with daydream running. This display sure drains lots of energy.
I do both, sometimes powered down other times in sleep mode. Don't see a whole lot of difference.
Here are some screenshots of just how long the battery lasts while idle:

Figured I would take these pics now since I will be using the tablet this weekend so I wont be able to show insane idle life anymore
hey guys could anyone help me with this horrible battery life???
I tried clearing the cache from stock recovery but it did not help me
I have updated to 2.1 and I can say that battery life was equally worse in 2.0.2 and 2.1

I wish I could say I have a solution but I have almost the same problem. With my opt, Google play services also is in on the battery drain. Would really like to have some tips. I've seen cases where one of these processes drains the battery, but not 2 or 3.
Very similar to my battery life. 2 hours screen on time, 12 hours off the charger, at 20%.
Do you have fingerprint scanner or tap to wake, and carry your phone in your pants pocket? If so, you may want to try having the screen facing away from you at all times to avoid accidental wakelocks.

Not OP, but personally I doubt it's that. I have charged my phone to 100%, then left it unplugged for 8 hours overnight for testing, and it will usually be at 80% the next morning. Most phones I have had won't drop below 90% overnight.
I just got my OP2 and it was at 93% when I started the initial setup process... after 44 minutes of setting up and downloading apps and the 2.1 update, it was at 52%. My Moto X Pure has "ok" battery life, but is much better in comparison... It only dropped about 20% during the initial setup, including ROOTing and doing a Nandroid.
So, I'm a little concerned about keeping the OP2 for this reason? Plus, the speaker sounds terrible.... But I've been using HTC dual front speaker phones for the past 2 1/2 years and most recently the Moto X Pure with dual front speakers. So the one speaker on the bottom is a bit of a let-down.
Guys, ok i charged my OP2 till 94% last night and left it. In the morning my battery was down to 54% and the major eatup of battery was done by MAPS. but my location was off and maps was not there in the running apps. SOT was 5 mins.
So, i am still trying to figure out as how to kill the Maps. But from morning (7 am) till now (3 pm), my batter was down only 23% and i have been constantly using my phone with SOT as 2 hrs.
Little weird but intersting.
WTF is going on with my battery? I have the S7 Flat snapdragon version (G930v) running the G930u software unrooted which removes all carrier bloat. Screen brightness is set to a little past half way. I have all setting provided by stock software optimized for maximum battery life other than running AOD. I am running a black Wallpaper/Lockscreen/ and an All black theme from the Theme Engine.. I Repeat, I have all stock firmware options Optimized for battery. Every single one. Wth hell is going on here. My battery time is looking Rediculous in comparison. Someone help me out here.

I feel asleep around 3am I guess with 89% and woke up just now close to 11. Heres battery over that 8hr period. 5% during that time. Standby drain is not bad it seems. But only 10hrs on 100% is crazy low compared to what some of you guys are getting.
End of Trial:
What can I do to get this increased.?
4.5 Hr of SOT is very Good. I am on the U firmware also and get 3 SOT. When you make comparisons, compare to SD Soc not the Samsung Exnos. You can download Gsam Battery and give it more permissions thru ADB and monitor. I noticed my proximity sensor (2) are giving high wakelocks.
The SD vs Exnos makes that much of a difference? I'm seeing people get 5.5-6.5screen on time in the main s7 thread. Granted not many relay the information as to weather they have SD/Exnoys or Flat/Edge.
4.5 hours when compared to 6 average over there, eh to me that's on the low end. I'd be losing my mind if I was only getting 3SoT.
I miss removable battery functionality.
Do you guys leave your screens on 24/7 or something? I use my phone quite a bit, but get 24 hours to a charge.
Is this ok?
At this brightness level plus I have turned off buttons backlight.

I get around 4 hours sot when I get home, here is my day with my phone.
730am start streaming audio books through Bluetooth facebook sms email.
4pm stop streaming books 75% battery.
5pm games facebook email sms.
10pm bed time, end the day with 330 to 4 hours sot and 15%battery remaining.
Can someone explain to me, please, what is going on with my S8. The drain is crazy.

Is that not normal? lol Mine pretty much looks the same. All my apps are at the bottom of the list but iam getting great battery life
what is your SOT?
i get same system usage as you but i 5-6 sot
4-6 SOT, actually, I thought Android battery life has evolved when I bought galaxy s8. But no, it keeps sucking my battery life even when it's in my pocket.
Unfortunately this issue is present on all samsung galaxy phones i've owned recently (s6 edge, s7).
I can't understand why the battery life is so bad and inconsistent.
No matter if all day wifi or mixed (data 4g/lte & wifi)
The background usage is pretty minimal. I don't understand why people complain that "something" however small is going on with the phone when the screen is off. The system is still alive, after all. Notifications need to get through, sensors need to be active to wake the phone (fingerprint, accelerometer, etc), apps need to be kept in memory, not to mention the always on display. Is it that surprising that if battery went down 10 percent during sleep 20, 30 or even 80 of that drop is due to these things? (that's what that reading indicates after all, 9% is not from total battery capacity, but 9% out of the amount drained).
Sorry for the rude rant, but people "expect" too much of the standby times.
Can the battery be improved? Certainly. Can the power drain be improved? Of course. But never to the point where it consumes absolutely nothing at all during sleep. Except if you turn the phone off.

20 hours on battery, 30%left. OP must be trolling.
Normal
I noticed finger print loves to break deep sleep.
4-6 hours of SOT? That's pretty good though... Same with what most people are getting including me. If I drained it all the way down I could probably reach 7 hours SOT. Totally beats the 3 hours SOT I got with my Note 5.

Did your previous phone with a 3000mah battery and a bigass screen get 4-6 hours of sot? I thought so...

Did you realize that when you total up the battery usage, you won't get 100% of battery charge?
