Hi guys,
i used to get more than 7 hours of active screen on my Nubia Z9 (3G browsing) - i have measured it one day during intensive day usage.
Now it's only 3 or so on current firmware.
Wakelocks seem to be ok, i don't have problems in sleep mode.
I don't remember which firmware i used before, i've changed a lot of them.
Battery itself is less than 1 year old and seem to be ok, i've tested it with Battery Monitor widget during several weeks and it almost did not loose capacity by now.
How to find, who drains the battery on this firmware on ACTIVE usage? Radio? CPU on abnormal frequencies? I'm pretty satisfied with new firmware, it's smooth and has a lot of useful features. But so much reduced active mode usage worries and annoys me.
I suspect the problem is Android OS itself, but why only in ACTIVE MODE?
I also want to mention I use two smartphones with identical set of apps and settings (including google syncs, etc.). And that second phone is doing fine in terms of battery drain. Second smartphone uses Snap 615 and this uses Snap 810.

Hi all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).
betterbatterystats is not available via market but I am trying out the XDA APK now

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.
Sent from my GT-I9100 using xda premium
as the main opera thread was shut down thought I might start a thread regarding it. not sure if its specific for samsung, so thought better to put into main android forum.
background: Galaxy Note running stock ICS (4.0.3) just upgraded from GB (not sure what version). opera mobile 12 - latest version from play store.
prior to update I'd easily get 2 days battery life out of the note with at least 2 hours each day of web browsing (usually much more). looking at the battery usage screen Opera would be responsible for 12-20% battery consumption.
since upgrading to ICS (and after disabling various crap like vlingo) I'm getting maybe a day (day and a half pushing it) - and opera is responsible for 40% + battery consumption. also whereas before I'd never noticed it (unless using flash based vid/games), the phone now gets noticeably warm when browsing. CPU spy suggests that its running at 200MHz for the majority of web browsing (1200 & 500 MHz for 2% respectively, 200 MHz for 36% and deep sleep for 56% - I did the airplane mode remove battery trick and it did get the phone to enter deep sleep properly). Better battery stats doesn't show any significant wakelocks (as far as I can tell at least - I removed netcounter as thats been made redundant with ICS, and that used to cause significant wakelock problems in GB)
possibly related I've found wifi speed and connections much poorer since ICS - though thats likely a device specific issue.
any thoughts solutions etc. the only thing I can think of is the force GPU rendering is off.
Screen darker than | 5 times darker than | normally possible thanks to Screen Filter app,
removed more than 70 system apps (I have less than 40 now) with the rest except absolutely essential being frozen,
WiFi GPS and all the rest turned off,sound muted, CPU and GPU undervolted and underclocked,(flashed 4.4.2 ROM and Dorimanx 10.43v98.4 Kernel which noticeably boosted battery life, especially after tweaking with the settings) disabled error reporting and everything else battery using I could think of while playing any game?
I doubled the battery life thanks to all the changes I made (read above) because the battery lasted barely an hour, often less.The issue was ever since I got the phone and I thought it was caused by the Samsung bloatware and Android 2.3.4.Being very UNsatisfied with the battery I bought a new one and it doesn't help except that I have double the battery life again (4 hours max) which is still very bad for Me.
The screen gets hot but the battery is even hotter and the area around the SoC (CPU, GPU etc) gets the hottest, I believe
**So is this normal? What else can I do apart from the improvements I wrote above to improve the situation?**
If a battery gets hot maybe try flashing different modem.Can eat alot of battery if it's poorly suited for your country.

Even with airplane mode on wifi always off, no simcard, phone etc apps removed? (In about phone baseband entry is blank!)
It shouldn't be so.
This could be a problem.Try flashing one suitable for your country or one of the so called global ones,like xxms2,xxms4 etc.
Wrong modem+ril may eat your battery even on airplane mode.
I just got my Alpha SM-G850F last week and I went straight to flashing 5.0.2 on it. After a couple wipes and reset to defaults it's now working fine but I'm still not happy with the battery life, especially while the device is idle.
My idle drain is about 3% per hour, which to me it seems a lot coming from a Z3c which usually has around 1% per hour in the same conditions (on WiFi at work or home).
Deep sleep seems to be active most of the time (according to CPU Spy), no rogue apps seem to be active (I even removed the official FB app for this tests) and I don't know what to look for anymore.
Here are the stats:
https://goo.gl/photos/fC5BbXqfZ8PpZFmy7
Some info on my setup:
- no power saving
- brightens on auto set to minimal
- location ON with high accuracy
- Bluetooth ON paired with G Watch R (switching it off at night does not make much difference)
- WiFi ON and connected
- Google Now OFF
- Nova Launcher instead of TouchWiz
- S Voice, S Health and the rest of S Krap disabled
I was wondering what's the average idle drain on WiFi for you guys.
PS: Is it normal that CPU Spy does not report above 1300Mhz (was it not supposed to go up to 1800) ?
First of all, Sony Xperia Z3 Compact has a bigger battery, 2600 mAh compared to Alpha's 1860 mAh battery. Second thing G850F has 2 processors, one clocked @ 1.3 GHz, second one clocked @ 1.8 GHz. I recommend turning all these settings off when you can (e.g. WiFi, bluetooth, location)
I've got a question though; does your touch screen work at the top left corner of the screen, like you can try swiping the navigation bar slowly from the top left corner and tell me if it goes back to its place (when im playing games buttons sometimes dont function)..
Best regards,
James
Of course there is a battery difference but still there is a big difference. Assuming the Alpha was half size that would still mean at most 2% drain. That's why I was asking for people to share their idle usage so I can compare. At the moment I'm flashing KK and I will report back after the weekend. I'm not about to dumb it down by turning off all the smart features that I use. I also remember I had the same high drain in the first version of lollipop for the z3c, but they fixed it in the meantime.
Regarding your touch screen issue, I saw your thread but I'm not experiencing it. I have no games to try with but in other apps I do not sense this issue.
Perhaps it's related to CPU usage which I assume it's pretty high during gaming ?
Battery is better in KK, idle drain dropped to less than 1.5% per hour, also memory management is way better and most of my apps are always in ram so they resume instantly, tho the system overall does not feel as snappy as with LP.
I miss the lock screen notifications and smart lock but I'm gonna stick with KK until a new version of LP turns out (hopefully 5.1.1).

I dont understand your statistics,but obviously Android system & kernel drain your buttery and this is not normally
but we have only first build of 502 jet,and I think newer version of 502 will be much better
Actually that's normal when you don't have any apps wreaking havoc in background when the screen is off. So basically what you're left with are the notifications, communication (WiFi, Bluetooth & GSM), location and the rest of the google/samsung stuff that you can't really control. Overall 26h with 1.5h SoT for such a small battery is reasonable to get you through the day.
Here is my idle drain after full charge and leaving the phone untouched through the night.

Power saving is off and I`m on Ozcan ROM. With my pattern of usage battery lasts for 2/2,5 day with around 2,5h SOT (no power saving and brightnes on auto 5).

Looks good. My battery went down about 14% over night from fully charged (as much as 20% on other 5.0.2 roms). Do you have exchange accounts? I've found them a bit of a drain in the past. I'll try again tonight and post some stats.
I have facebook, messenger, snapchat and 4 gmail accounts that have push notifications. I also use greenify with experimental functions enabled - it indeed saves some battery power.
Hey guys, I am using Accubattery to monitor my battery performance and I noticed that after the last software update the battery performance dropped significantly. On the previous version, my stats were roughly 9%/h screen on and 1,5%/h screen off. After the update, the screen on discharge jumped to 22,9%/h. I used to charge my phone once in 3 days, now I have to charge it every day. Also, I noticed that the phone was significantly warm while reading an ebook and drained the battery really fast.
Something is really off. Any idea how to report back to Realme?
Seriously, no one has a similar issue? I tried pretty much everything except for a full factory reset. I tried to turn off GPS, LTE, Wifi, and Bluetooth with negligible improvement in battery consumption. I froze and force shutdown Zepp app and Notify for Amazfit ( I bought a new Amazfit watch recently) - with no visible improvement. What helped - at least a little bit was Battery->Performance mode->No performance improvement. Smart performance mode causes huge battery drain and the phone gets significantly hot during normal usage - web browser, ebook. etc.
I checked if there is a misbehaving app - nope there is not. Checked for malware, just in case - no problem there either.
My theory is they somehow tweaked governor in an update and screwed up.
I get some weird data from AIDA and CPU monitor. It seems that the triple-core cluster is running at full-speed 2,42 GHz all the time. That would explain the battery drain.
Check this screenshot.
The latest update to Android 11 and Realme UI 2.0 seems to fix the high battery consumption, also the tri-core cluster frequencies are finally adjusted normally.
I just hope they didn´t introduce more bugs with the latest release
