[IMPOSSIBLE] Battery drain while the CPU is in Deep Sleep [BetterBatteryStats]

Hi,
i managed to get my standby drain on unrooted stock 4.2 to 0,5% (WIFI) to 0,8% (HSDPA) per hour with disabling some stuff that i dont ever need.
Market notifications
Latitude
Google apps like Currents, Play movies, Play books etc...
This is great, but sometimes after usage it still felt like the battery keeps draining as the phone is in use with the screen turned on.
What now happenend is really weird:
I did set a custom reference in BetterBatterySats and left the phone on the table for 1 hour. No unneccessary apps running in the background. But it drained 7% in this hour. As you can see in the screenshots, the device was in Deep Sleep most of the time and there are no noticeable Partial Wakelocks.

But how the heck is it possible that i lost 7% in one hour while deep sleeping? Is there any sort of app that can tell me in this particular case what went wrong?
Any info is highly appreciated.
Best,
ras

k9 mail seems to be one of the culprits

nope. it polls 2 accounts every hour anf therefore uses cpu time of approx. 0,4%. thats even even the case in that "awesome battery life" area seen on the last screengrab. a total of 15 sec. cpu time can't hurt that much.

This may sound silly but did you try just to restart the phone?

im pretty sure that this would fix it.
but because this happens from time to time (though this is the first time i can document it because auf BBS) i want to know whats the cause of this. it is pretty annoying to leave a phone on the desk and to find it drained empty a few hours later. this would have happened if didn't pick it up after one hour.

I get a similar problem too. Only way to clear it is a power down and restart.

Well, first of all, can we really be sure that those 7% aren't within the battery measurement margin of error?
Considering of course stuff like temperature, sensor's reading delay and other electrical/chemical/whatever stuff the battery may go through after heavy draining like you show in the graph?
I really don't think that % stats are that accurate, but that might just be me.
Some guy disassembled his Nexus S and measured the energy drain with accurate reading devices. Maybe someone should do the same on the Galaxy Nexus. Because if one software says there's no cause of drainage and another say there was some drain, maybe one should confirm which software should we rely the most.

maybe it happens because the voltage still gets down because of heavy use before. if this is the case the drain should stop at some point and the battery should not die completely.
i will def. keep an eye on this.

Its the fundamental problem with android and our battery technology.
One of two things need to happen, Google needs to get their act together (think project butter but with battery) or the OEM's need to start providing better battery technology. Its ridiculous that over the past 3 years there have been NO significant battery technology improvements. Yes, processors are becoming more efficient and using less power, but that is only going to take us so far. **** needs to happen and Google needs to press it.

Battery life on extended battery?

I have a GSM Galaxy Nexus. The performance is still adequate for my needs(Whatsapp, social networks, browsing and occasional lightweight games). The only thing I hate is the battery life, and am considering getting an extended battery to fix that.
How's the battery life on extended battery? Please leave screenshots and brand of battery (I'm leaning towards Seidio, but am open to suggestion).

Hi! I have an extended battery (2000mAh) and the performance of the battery is very good. I achieve 3 days with 2 or 3 hours of screen with only one full battery charge. Unfortunately I don't have screenshot right now to post but the performance of battery is highly dependent of the apps that you have running in background in your phone. It is very important that your phone is in deep sleep mode the most time as possible while the screen is off. In my case my phone is more or less 96-97% in deep sleep mode when I don't use it.
The battery is original Samsung .

On the CDMA variant with the oem extended battery it's reasonable to get a day with moderate use, moderate signal. So for your phone I bet a 50% increase over that is reasonable

Mostly on WiFi, with a couple of hours of 3G(<1 hr SOT on 3G). Location reporting off, WiFi always on. Brightness auto.
Purity ROM 4.3. Stock kernel. I started with a clean install to avoid all effects of botched upgrade, and slowly added back apps.
Things I use: Greenify for all apps except IM, Wakelock Detector and Battery Stats Plus to monitor rogue apps (haven't had any yet, touchwood)
Things I don't use: undervolting/underclock, custom kernel.
The area I live in has less than ideal signal strength (3G), so my battery life is almost always less than what many people get and benchmarks show.

Damn! That's like my Wind connection!
I get a pretty solid battery life though, around 4 hours SoT and that's with checking flipboard, facebook, instagram and my bank quite often. Also playing those 'clash' type games. If I don't use it much it lasts almost 18 hours. (Mild calls, answer texts only and minor music playback.) I'll post screenies tmw because I've been charging every time I get home so you would see unrealistic statistics.
Using AOKP with ROM packed kernel and no kernel changes.
Usually using CM nightlies (4.3) and tiny kernel (around 5 hrs SoT with interactive and deadline.)

Not to second post (it won't let me edit for some weird reason) but I pretty much do everything the poster above mentioned as well! (Greenify and location off, auto WiFi off and auto brightness.) Also used trickster to use morfic colour settings but haven't needed too on AOKP.
Edit : I also bought greenify donation and use xposed framework to do system apps, not sure if that matters or not.

Battery Impression thread.

Hi fellas..
I thought we needed one of these threads to get a clear image of how the phone performs IRL.
We all heard rather varying reports from the reviews, some good,other disastrous...
Here are the points to be considered while posting.
1. Please post your impressions of the battery here.
2. Please be specific about how you've used it during the day.
3. Screenshots of the battery settings are most welcome.
4. Show image of screen-on time as well as the list of apps
5. Brightness, is it auto? custom? If custom, %?
5. 3g / WiFi on? If yes for how long?
7. Haptic feedback?
8. Please share the details like which ROM,Kernel, MODs. :good:
​
Thank you!

I would also love to see how the battery performs. This is one of the main attractions for me. I understand that the screen is absolutely massive, but If I can get a full day of use out of it without needing a 4:00pm re-charge (my iPhone 4s) than I would be eternally grateful. I can't stand having a dead phone merely 8 hours after I charged it. Some days it`s dead by 2-3

I can't recall any reviews saying anything negative about the N1's battery?
Regardless, great idea for a thread -
I have been very curious how much the 'gestures while screen is off' affects battery life, in particular.
- Frank

The battery on this thing is a beast. It isn't perfect, and I'm sure it could be improved somewhat, but it dominates everything else at the moment.

I think this is the best thing I've heard all month. Finally a great battery in a great phone! I would sacrifice a bit of CPU speed for battery life any day.

Does seem very decent!
Can't post any specifics right now, but the battery does seem very, very good!
I've had the OPPO Finder (x907) which was a cool device but even with even very minimal use could barely make it through the day.
I'm using the OPPO Find 5 (x909) which has decent battery life for a light-medium user, but would displease most users and all power-users.
With the OPPO N1, I'm still evaluating it's battery life but so far it's ridiculously better than the OPPO Find 5. Perhaps with the CM11 rom this will improve even more. Another cool thing, because the screen is so big...you can turn the brightness way down and the screen is still extremely readable.

Great to hear that there is a large improvement over the find 5. "Return to innovation", as they say . And I never would have thought that the screen would be easier to read when dimmed due to the large display. It makes sense due to the fact that the letters are displayed large enough to still make out clearly while the screen is dimmed. Neat!
Regarding the brightness, could you perhaps take a day to operate and monitor the N1 while on low brightness? I'm curious to see how much better the battery performs while in a dimmed state. To see if it makes a noticeable difference.

N1 Owner
i used OPPO Find 5 as a daily driver it was doing ok, but once i got N1 it amazed me with it's battery life, sometimes i can use it for two days
or one day for full heavy use, which means around 4-6Hrs screen on, with Wifi and playing games (candy crush sometimes for 2-3 Hours) and it still got some battery life.
I really recommend it.

Anyone else using the snapdragon battery guru app? I have to wait another 3 days for the battery savings to start. I was using it for half a day yesterday but I was forced to reinstall when I tried to install some see-through CM theme that messed up the themer. So beware of that.
I can actually play games for hours at a time on this phone. Whereas on my other phones the heat and battery drainage prevented me from doing so.

Good Battery Life
Battery life is pretty good for heavy users too. I won't say its the best, I think Note 2 was better on TouchWiz, but its not bad by any yardstick. If you are worried about battery life, keep that aside in case of N1 while using ColorOS. I can't speak for CM or Omni atm.

Battery life is pretty good.. Depending on the OS I use. WIth CM10.2 which it came with I am usually able to get about a full days worth of battery life with around 40-50% left. Obviously depends what I do with it during the day. Most of the time I surf 9gag, read emails, chat. The usual. I occasionally use Plex to stream media from home which drains the battery more.
I noticed when I used ColorOS though, the battery life was severely diminished. I use the program Battery Widget Reborn which gives me a rough idea of how much battery life is remaining. on CM10.2 it would report a full charge can usually last at least 1 and a half days to 2. But in ColorOS, the program reports that on a full charge I can only use the battery for 23 hours. In reality, I normally find myself at around 20-30% when I go to bed. (the phone is generally unplugged at around 8am when I head for work and replugged to the charger at around midnight.)
Both were pretty much configured the same with 3-4 widgets on the home screen with nova launcher and Zedge changes my wallpaper every hour. I read emails often and do chatting occasionally. and surf 9gag often.
I would be disappointed if the N1's massive 3610 mAh battery couldn't compete against the other flagship phones especially when the other phones all use the more battery consuming LTE radio vs Oppo N1's HSPA+ only radio chip.

About battery life - my statistics...
I have just played with my brand new toy, so it is not a normal use for me...

Although many reviews point to battery darin in CyanogenMod version, i find it very practical than ColorOs. Battery life is fantastic in the two versions, but i love the feel of stock android rather than ColorOs.

my personal review about its battery is actually
depend upon its battery capacity....
for example. We've found here,
the non-famous brand with a power of 1500mAh,
it seems a little,
but if we compared towards its performance with its high usage,
it is still fine.

How I've had really great battery life and decent performance on the One m9

So I think I've found the best way to manage the heating/battery issues of the Snapdragon 810. I'm not sure if its my entire setup that's correcting all my issues or if its just the primary app.
My setup is Leedroid ROM with power saver on but only for display dimming and CPU managing. The important stuff: I am running the CPU Tuner app with a custom made profile running the On
demand governor at a 50/50 powersave bias (slider in app), and running only 4 cores out of 8. I believe this completely removes the high-power/performance cores from running. However, I do barely any gaming and performance for all other apps is very snappy and more than acceptable.
Just figured I'd share my thoughts and setup. My hands have yet to get uncomfortably warm like they usually do when doing multiple things in apps. Battery life is also MUCH better. If anything, you may use this setup temporarily until we get more kernels and developers working on fixing the issues with the snapdragon 810.

I don't have any issues with the snapdragon 810. I am still all stock unrooted and average just over 5 hours SOT. I don't use powersaver at all, not even when the battery falls below 15%. If battery life is that bad for you that you have to go to those extremes, then you probably have issues beyond the CPU.

I don't know how that's possible running stock, unless I have a bad unit or something. Then again I've tested some coworkers M9s, and theirs have issues the same as mine even though they're stock. I don't even have many apps installed, but my battery plummets just browsing the web or reddit, until I cripple the 810. Do you have any apps at all that help to preserve battery life? Or run exceptionally low screen brightness?

No, I do not use any apps to improve battery. I am on AT&T and at home I use a microcell and WiFi, so I do not get much battery drain from lack of having a good signal. I do not use exceptionally low screen brightness, but since high brightness does hurt my eyes, I do keep it around 33% and only raise it higher as needed. Overall, in comparison to other devices I have used and have or have had in the household, while not the best, I do find the M9 to have good battery life. And another good thing is, there is this update coming that improves battery life. Here is a current screenshot. Not half way through the battery and I already have 9 1/2 hours of life and just over 2 1/2 hours of SOT.

There's nothing wrong with your phone, the M9 hasn't got great battery life period, you can squeeze a lot out of it if you go to extreme lengths or if you don't hardly use your device, for example my last two phones which i just got rid of (Note 4 and an iPhone 6)
The Note 4 would last over 1 day comfortably as it was my main phone, the iPhone 6 however was simply a work phone, this bad boy lasted 4 days and 22 hours on a single charge, running IOS 8.1.3. I have a screen shot of it at home on my PC i'll upload later, the point i'm trying to make is, this is completely down to your Apps, your habits, your set up, rom you're using, mods installed etc.
All these combined make up the footprint of how long your battery lasts, no two people are the same, just as no two CPU's are the same, or for that matter the battery in your device, some may have a really good one, some might not, even your signal can have an adverse effect on the battery, especially if it's low and trying to get the signal out.
My advice for better battery life is to set up your phone the way you want it, start by cutting out the dead weight, remove and apps that start up at silly times (use autostarts for this) , check for wakelocks, reduce wireless activity, modify the CPU settings (like you have already) and then just use it as you would, anything else you can cut out,any other accounts that you really don't need, lose them, avoid task managers like the plague and remove apps like better battery stats once you've used them, use manual brightness, turn off ambient display, turn off hand gestures like double tap to wake
Beyond this there isn't much more you can do.

Battery Usage time

Greetings everyone,
I bought a verizon G4 yesterday and I was surprised that its battery won't last long as I expected, even with normal usage. It takes 10% for like 15-20 mins. while it was way more better with my beloved stolen G2...
What I am asking you (Verizon G4 useres) is to kindly share your experience with the battery here (preferably with screenshots) to be like a reference for other users ...
Here are screenshots of my device usage :

So you mainly use it as a player more than a phone, is that right?
And what about when you use it like moderate to heavy use?

It can be returned in those few days if there is over consumption of the battery...

as soon i get off work i test it. i got my 2nd battery on the charger right now so i start useing it at 4pm. as i use my phone i make notes to what i use
please note my phone is rooted and debloated

Im down to 92%on battery i now will do web surfing and playing music for a bit

Ok im down to 83% did some web surfing video watching and music playing. The battery is fine to me here.

Thanks LASERWOLF452 for sharing it, can you take a screenshot for the "screen on" time for a final comaprison. Also my g4 is technically debloated as I disabled all verizon apps through app manager.
Again thanks for your cooperation ?

Ya sure and you are welcome. Also there are tips and tricks to save battery. I work at a facility and there are dead spots. Ware i work at is a dead spot that i get 1 or 2 bars and my data rannges from 1x to 3g. To the best of my knowledge 1x and 3g will burn out your battery cause the connection is slow and the phone is trying to get the best out of the data. 4g 8s fast for the phone and the phone dont stress out as much as it will do on 3g and below. I also manage mt screen brightness. If i be in the biulding all day just for my music i dont need auto brightness unless i be useing my camera. I use it as a 3rd eye as i am ligely blind (20/200). I usealy walk out at the end of the day with 50%. If u are in a dead spots turn off mobile data and you be fine. Also clear you recent apps and do some software cleani g on the phone every week. I also carry an extra battery incase i need it. Hope this helps

Thanks for the info. Funny thing I use it in Yemen on a CDMA network with very poor 3g coverage only. And ineed it consumes less battery % while being offline.

Optimized my phone for battery life over performance. Have not been happier.
I use my phone mainly for e-mails and web browsing.
Yes, I am rooted.

SOT is sitting at: 2 hour 32 minutes. I have the TrendON 3000mah battery as well.
TrendON Battery Link

Finally, I have done root, installed Xposed, debloated my g4 and installed Greenify.
Feeling way better than before in battery consumption and control over a weakened beast by a bunch of useless apps...

I have spent a LOT of time tweaking my G4 to get good battery life and it is still not what I would expect. I have:
Rooted
Installed Xposed
Greenified all user apps
Installed Tasker and created a task that Greenifies all apps as soon as I shut screen
Shut SystemUpdateService from Google Play Services
I am constantly checking BBS to see if anything is keeping my phone awake. It is a never ending fight and I don't want to keep doing it to be honest. I have done way more to save battery with the G4 than any other Android device I've ever owned. I am a disappointed owner to say the least.

@pettigrew95
Greenify doesn't need a tasker to do its job when screen is off + try deep hibernation it could be helpful... + you can cut wake-up activities per apps...
I agree with you G4 is disappointing compared to the G2 but on the other hand G4 offers better display and performance than any other older devices...

Greenify takes several minutes after screen off to hibernate your apps. I have Tasker set up to have Greenify hibernate them 2 seconds after the screen shuts.

I've managed to get almost an hour SOT for each 10% battery. Internet is on, browsing and social networking only...
What I am using is Greenify with Xposed, disabled bloatware with titanium backup and disabled the highest 2 cores and underclocked GPU one step with 3C CPU manager.
Performance did not differ that much and heat under camera has been greatly reduced.
Hope this info. was helpful ?
