"Battery Use" inconsistent with actual usage

The "Battery Use" reported by Android is completely out of whack on my Epic. It's the one under "Settings" and then "About phone."
For example, it's listing "Voice calls" as accounting for 83% of my battery use with 3h24m29s of time on. I know for a fact I've only talked on it for ~5min today. In fact, I was curious as to why it was showing 34 mins when I checked it at noon so I kept checking it, and by 12:15, it was showing 1h35m! Totally bizarre, not to mention most of the other battery usage times are off too, including a cell standby time that's shown to be longer than the time that the phone's been on.
Anyone else having this issue?

Haven't noticed this yet, but I'll keep an eye out for it. Out of curiosity, the battery drain isn't any different though, right? Your battery isn't being drained as if you talked on the phone for 4 hours?

Honestly I can't say. My battery life has been horrendous from the first day I got the phone. Have yet to make it through an entire workday with it. That is even when it just sits in standby when I'm at work. I don't know if that has anything to do with this usage indicator issue. But I went to the local Sprint store today. They didn't really know what was going on so they gave me a new battery to try out. I will report back if anything's changed.

Make sure you condition it real good. Like for the first week, give it a full charge then use it until it dies. I've done that and ran the battery until dead on purpose about three times the first couple days. If the battery is good, the life should get better and more stable. Also I suspect that, after speaking to the dev of battery indicator pro, some brands and models of phones report a ballpark figure and some are just about right on the money. My battery has noticably improved after these full powering cycles and topping off a few times after full.

Well, hopefully that fixes it. I've talked to a few people who have gotten amazing battery life using JuiceDefender to automate turning the 3G connection on and off, which people seem to all agree is the biggest battery killer sans display, and they are claiming going from 100% battery to 95% battery overnight, 2AM to 10AM.
If I leave my phone alone for an hour I will lose that much, and that's with the same JD settings. Then again, even with my EVO I found JD to be nearly worthless. Right now it's claiming 2.11x more battery life, but if it equates to anything in actuality I might be gaining 10 or 15 minutes. Maybe.

Mine is the same way. It sits on standby most of the day. But it still eats up the battery and the phone is always warm.

If 3G sucks as much battery as suspected, then google needs to put a button for it into the Power Control Widget (1 of my favorites).

Sounds like you are suffering from that bug where the phone is always looking for a gsm signal instead of just locking into what it works with cdma.
Press and hold the power button, select airplane mode. Let it sit in airplane mode for a minute and then repeat above steps to disable airplane mode.
Your time without signal should drop significantly thus resulting in a cool phone and much better battery life.
You need to do this every time you reboot the phone by the way. This bug should hopefully be worked out with the froyo update.

Reporting back after new battery and factory reset - still broken. "Battery use" says "Cell Standby" has been on for 20mins after the phone's only been on for 11mins. Seems to be an Android or Touchwiz problem.
Still waiting to see if the new battery will carry it through a 8hr work day. If that doesn't work, then I'm trading it in for an EVO. Too bad since I really liked the physical keyboard on the Epic.

Yep, problem I have is where I live I dont get any signal. I end up roaming thus causing the radio to kill the battery extremely fast. Last night i put the phone In airplane mode and let it charge. Phone cooled down even though it was charging.
So unless I get better signal without Roaming or I move I guess I am just stuck with not being able to use my phone at home or at work.

on mine my battery meter is all off also. my battery widget shows that my phone its at like 40% while my icon in my notification bar is pretty much full like it would be only at 70%... its not even more than half gone. so I know there is an issue with how my phone reads the battery or something

[Q] Questions regarding battery life

I had searched previously and read some things about this "bump" charging stuff supposedly getting you many more hours of usage on a normal schedule.
Actually, guess I should preface with some background info. This is my first android phone, but I've been watching since 1.6 came out. So, the day I got my Epic it was rooted and I flashed Nebula ROM on it. I also tried out Epic Experience, but was more pleased with Nebula. Of course I'm running DK28 with the modem fix.
On to my question. What can be done to increase battery life on a fairly undemanding schedule, without causing the device itself to operate less smoothly?
I tried several of the bump charging methods I saw, but I'm sitting at 33% battery after 5:45.
I'm going to feel dumb if this is actually average and I'm just expecting too much, haha.
Thank you, kindly.

You can try calibrating your battery. If you don't know how, well here's some instructions:
To do this, all you have to do is let your battery completely drain. Then while the phone is off, charge it for around eight hours straight without turning the phone on (have it just showing the battery icon).
Since you are already at 33% or so, I'd suggest just letting it drain today, and have it just charge overnight.
I, too, am running the Nebula Rom, but I haven't tested it for a full day without charging it yet. So, you can try calibrating the battery if you would like to see if you would get any improvement, but in my opinion, 33% at 5:45 sounds great. I'd be satisfied with that.
Please let me know how it all turns out.
Hope this helps!

Thank you for the speedy reply, I will try that.
I wasn't really expecting 33%, but more around 50%. I've only sent three texts today on it (as I was trying to see how well it'd hold up) and so I assumed battery life would be fairly high. But I am also living in an area with extremely poor coverage, so bad that it'll start searching for signal if I move the phone 2 feet away. So maybe it is trying to acquire a signal often.
I'll report back in the morning. Any other advice/ideas would be greatly appreciated.

Well, there's basic things as well.
Check to see if Data Roaming is on, make the brightness Auto, no live wallpaper, no bluetooth, no GPS, No background data/Accounts Sync.
But you shouldn't have to do ALL of those. Just a couple if you haven't already to boost the battery a little.
And yes, searching for a signal could be the problem.
And only three texts? Nothing else? Maybe there is something wrong.
Tell me the results tomorrow after calibrating the battery.

I'm using midnight rom and I'm at 20h26m and 33% with moderate usage. You can try recalibrate and wipe 3x b4 install the rom. It might help. Good luck.

Alright, it's 9:20 EST and I'm starting off with 96% battery life. I'll gauge how it holds up through "normal" usage, which is somewhat less conservative. Wifi will be on nearly constantly, my signal will be weak unless I leave, autosync is set to hourly with background data.

I normally get about 12-16 hours on what I call moderate use.
I leave gps on all the time. I make ~6-10 calls a day for 5-30 minutes. I send and receive ~30 texts a day. I'll put an hour or two worth of internet time per day. (not watching videos)
I kill the drm and friend locator services on every boot. This helped my battery life a lot.
It does help to train your battery dragon occasionally.

Are you saying to turn Data Roaming on or off? I could come up with a reason it would help either way, so do tell.
Same thing with Auto brightness, I would think that actually uses more battery than a fixed lower/medium brightness.
Do people on here really leave Sync and GPS off?
Compared to these settings, I'm completely lazy, and still get good battery life.

Turn off Data Roaming. The reason being is that with it on, your network will constantly search for data, and that drains the battery. The brightness I am actually not sure on. I have had better results with auto rather than, say, 0%.
If you get good battery life already, that's fine. But auto-sync isn't really necessary in my opinion.

Alright, it's been 5:33 since it's been unplugged and I'm sitting at 68%. This is with wifi on the entire time, brightness set to auto, and data roaming off (no need for it to be on, I was considering toggling it based on my location in Tasker). Sync is on and I rarely have use for GPS in my day-to-day so that is off.
So I think the calibration as recommended by Acer1096xxx has effected the life of my battery for the better. Thank you, once again.
Hopefully this thread will help others out in the long run. I'll continue to monitor my activity and battery life.
EDIT: 57% as of 5 o'clock. Had to plug it in because I'd be going out tonight doing things. Overall, this is about the performance I was hoping.

Specific battery life issues

I have had a rooted atrix since release date.
The battery life has been frustratingly bad.
Right now (9am) I am at 86% with the screen having been on 26m.
It's very very very common for my "running" time in spare parts to be 2-3x my screen on time.
Partial wake usage is led by the process: UID 1001, followed by Android System.
Network usage is dominated by process "0" followed by android system. "0" is so far in the lead it is unreal.
My total in all time stats are:
Running 28%
Screen on 14.1%
Phone on 1.5%
Wifi on 30.5% (??????????????)
Wifi running 17.3% (Even more ????????????????????)
I have frozen all of the recommended freezing apps. I have beautiful weather set to refresh every 2 hours. Facebook, twitter, etc, aren't set to notify me at all. I have no idea why it's so bad.
It's coming to the point where i'm about to give up. My nexus one gave me better battery life.
I've already tried a factory reset, is there something i'm overlooking?
What is UID 1001? What is "0"?
The most frustrating phone I've ever owned. It is so close to greatness. I wish I could get rid of this terrible terrible terrible motorola blue garbage.

I've been struggling with battery life too for some reason. If you have Tango installed, get rid of it. That app didn't let your phone sleep and drained battery. Now my problem is the sensor usage when I check my battery history in *#*#INFO#*#*. Android system has been using the sensor 100% of the time for me. I factory reset it, but that didn't work either. I'm really contemplating going back to my N1 too, which is such a shame since this Atrix has so much potential

Do you have 'autosync' turned on?
P.S How long until your phone goes from 100% to 0%?

Has your phone ever gotten down to 5%-10% or do you always recharge it before then? I've had issues in the past where a lith-ion battery loses lots of its capacity until completely drained and then completely recharged. It seems way to early for this for you, but it might help. From my limited experience, gps is very very costly in terms of battery.

Draining a li-on battery completely more than once a month damages the battery. It's a very bad practice.

I'm having the same issue with UID 1001 under Partial Wake Usage and I also have the 0 under Network Usage. Under Partial Wakelock it shows UID 1001 and a total time of 7h 7m 30s under Total in all time. I've tried a hard reset and still showed up. Have you guys checked to see if you are getting the same thing. If people are getting good battery but have this then I'll feel a little better. I just thought it was weird. I still get this even with WiFi, BT and GPS off.
Under Network Usage the 0 is pretty much all blue all the way across and a little bit of pink at the end. If i try to click on it "Settings has stopped unexpectedly" message.

The battery doesn't seem to last as long as my n1. With my n1 I still have roughly half when I get home from work. The atrix was at 30 or so when I got home today and its been similar most of the times.

I am also not terribly happy with the battery usage. Maybe its because I have WiFi on all the time?
Also, just having bluetooth on (but not connected to any BT devices), shouldn't be a big drain on the device.
The main auto-sync feature I have is Exchange push notifications. Gmail only syncs every 3 hours.
I also have device running time on Spare Parts higher than Screen On Time.
I am going to try a factory reset and add applications one by one to see if that has any effect.

I've let it fully discharge once. I just can't sort it out. People in the other threads are getting 1+ DAYS uptime.
Sent from my MB860 using Tapatalk

With light usage I was originally down to about 20% at the end of the day. That's now improved to 50-60% charge after installing the 'green power' app recommended in another thread and further improved by turning off the auto brightness.
Auto brightness is good but needs to be reduced by about 30% to be useful.
Gps Navigation with google is the biggest battery drained I've seen so far. Its on the order of using 1% charge per minute. Im hoping that an offine nav app will be more efficient.

There are a lot of reviews stating that spareparts IS the cause of battery issues. Maybe uninstall that and use the built in battery manager to determine use?

Really? It seems to just be a monitoring app.

SNS battery dead in 6 hrs or less.

I am posting for a friend that has a SNS. The couple of days he has been draining the battery in about 6 hrs. I looked at the battery usage and it said that the display was at 60% and the graph shows a constant fail of power. I checked and he has the screen set to auto brightness and the screen times out at one minute. The only other thing that I cna think of is that he has poor cell coverage but we are using wifi in that location which his phone is connected to. I understand that poor cell coverage causes power drains but with the major of his data going through the wifi one would think that the cell power drain would be minuscule. Thanks in advance.

It depends on how weak. Data is not going to route over the cellular network, but it will try to maintain a connection for things like calls. Thus the phone will attempt to maintain a connection to the tower unless airplane mode is enabled or the cellular radio is otherwise disabled.
If the signal is really weak then the gain is going to be automatically adjusted to try to boost the signal - this is going to cause an increase in power used, sometimes substantially. If you spend most of the day in this situation then you don't have many options currently if you want to receive calls on the phone (you could look at a SIP solution).
If you don't care about receiving calls just turn on airplane mode and then toggle wifi on.

You need to provide screen on time and awake time. If he just got the phone and is using it a lot.... well then six hours is not bad for an android phone.

Not really. Maybe 6 hours continuous use, something like 3 hours display at 20-50% and 3 hours talk time; that would be normal. But 6 hours low-medium use points out that something is indeed wrong.

60% display means the phone was on and actively used for over 3 hours. That's a fair bit but isn't too much really, but it depends on what else is running durng that time. As mentioned, awake time is also important because it means the phone is actively working at something even though the screen is off. He may have a rogue app that he installed sucking power. Or simply leaving the web browser on a webpage with a regular refresh cycle will cause the browser to continue to run in the background keeping the phone awake while the screen is off. I've gotten in the habit of going back to the google home page when I'm done browsing to make sure it's on a "dead" page.
Anywho, more details are needed to figure it out. Just saying it's only using 60% display isn't enough to find out why the phone only lasts 6 hours. Mine lasts between 24-48 hours depending on usage from heavy to moderate. With light usage I figure the battery would last 3-4 days, but I'm not that light of a user and I generally top up every night anyway as it's better to top up a Li-Ion battery than let it run down all the time.

Huh???
When it says "What's been using the battery" and it says "Display........ 60%"
that just means that the display is responsible of 60% of the battery drain that has occurred since last boot.
For example, if you were at 100%, then turned your phone on for 5 minutes and scrolled back and forth on homescreens, lets say your batter went down to 95%. Well, if 2.5% of that 5% loss is from display, and 2.5% is from Android System, then when you check the battery screen it's going to say "What's been using the batter?"....... Display - 50%; Android system - 50%.
If you did the same thing for 4 hours, and the battery drained down to 20%, you might still see...... Display 50%, Android system - 50%.
In other words, the % has nothing to do with how long the phone has been on.

also if screen on time is 3 to 4 hours, yes the battery will be very low by then.

Thank you all for the advice. As I said this is my friends phone. i don't see him using it a lot we are both programmers so we use a computer for most everything, and we have both our phones on wifi because of the terrible cell signal. I will ask him to try and keep up with everything he does to see his use patterns to see how much he is really using the phone. I will post later on what apps are running and his amount of use. The main reason I am not sure is because this has just started happening with in the last week. We have been in the same location for 6 months and it has just now become a problem.

Hmm...ok that kinda helps, but it doesn't really explain what's happening when it uses that setting. I know that PRL means preferred roaming list, and GSM Auto means it selects automatically, but how it selects and why it uses less battery is what I want to know.

Doze not what expected

When I got my N6P, I had expected standby time to be amazing thanks to Android Doze. My first day of use shows a lot of "awake" activity during the time when the phone is sitting on my bed side table, completely motionless.
Has anyone else had experience with their N6P doing the same? Am I doing something wrong that caused Doze to never activate?
As a frame of reference, when I went to bed the phone was at 47%. I took the screenshots when I woke up this morning.

Sorry if this is a silly question, but you have activated it haven't you?

I activated mine when my phone arrived. Settings>battery then use the battery menu and select battery optimisation.

Very frustrating reading replies that say Doze must somehow be turned on. It DOES NOT have to be turned on. It's interwoven into Marshmallow automatically.
You can tinker with battery optimizations within the phone's battery settings, but that's about it.
Note: If your phone needs to conduct maintenance (update apps over WiFi, etc.) doze may not kick in the way you think. If your phone has nothing to do and is sitting still for an extended period of time, it'll enter Doze and only sip battery.

You can try greenify beta it has aggressive doze when screen goes off, just whitelist the apps you need to notify you immediately.

Sorry, my bad. Battery optimisation is separate from doze then?

I'm seeing the same problem. 20% depleted in 7 hours overnight just sitting on my nightstand. Deep sleep in better battery stats showed 95%. Not sure what's going on.
How's your charging speed? It's nowhere close to what others are seeing. Even though it shows rapid charging, the amount of time to fully charge is high. 3 hours from 25%. 45 mins from 85% etc. Are you getting fast charging times? I can understand some process binging on my battery while running. I'm getting no more than 3 to 4 hours screen on time. But I don't understand why I would have slow charging times. But if you are also seeing slower charging time, then perhaps it could be.

That's just a feature that lets you decide what apps can override any kind of battery optimization

Lost 1% in 6 hrs last night,make sure all apps are optimised in doze setting

Looks like it could be Tasker. I'm going to uninstall it and see what happens.

Doze works great for me. For example, during the night, I only lose like 3 percent battery life. That's pretty freaking low. It's like I went to sleep at 75% and woke up at 72%. Very effective imo.

By the looks of it, doze should be on by default. Going into settings/battery/battery optimization-just shows which are optimized and which aren't. It's not an on/off thing.

The only apps I can't optimize is Android OS and dm service. What's dm service anyway

Unfortunately, that's done nothing. Lost 5% in 1 hour just sitting. BBS shows 76% in deep sleep. Screen on 1%. Awake (Screen off) 25%.

This was about 5 hours untouched on my table last night... Working fine...
The the thing I don't really like about doze is, it only works if the phone is flat on a table... Any type of movement, be it in pocket or even on the car dash, it won't come into play...

That horiztonal bar (a clear indication of Doze) just doesn't happen when leaving my phone overnight. The "awake" bars at the bottom of the battery screen in Settings is also switching on and off periodically when the phone should be dozing.
Does that mean a third-party app is the cause?

My guess is yes, some app is staying awake.
It would also explain slow charging....something is eating up CPU cycles and preventing the phone from idling down and sleeping.
It isnt just a 6P thing either....my LG G2 with numerous ROMs/kernels has occasionally experienced issues like this. Almost 100% of the time it could be traced to an app that was misbehaving. You can use a battery tracking app (GSM battery monitor, better battery stats, etc) to get more detailed info. If you arent rooted Im not sure how detailed the info can get, but its probably a lot better than the stock battery graph.
