Hello,
I have a problem with my tablet Shiru Emperor 10 (Cube U9GTV, Cube U9GT5, Visture V97HD). In standby mode, regardless of whether it is WiFi enabled or disabled tablet has lost an incredible amount of power.. I've tried to do everything. I removed from the system all the possible applications that might force the search network (Tablet does not have 3G modem), but it does not give any effect. I tried to analyze the statistics of the program BetterBatteryStats and the program WakeLock Detector, but I'm green in this topic. It is worth noting that when using the tablet "holds" on the battery really solid, as it should be. Sometimes I get the impression that the faster the battery out when the tablet is not in use.
Today in the morning I tested tablet again by 12 hours and has lost 40% battery in standby mode with WiFi turned off! Below is the today statistics in standby with BetterBatteryStats program and I'd asked some wise person in this topic to check what is wrong.

Hi,
I have a GSM version of Raphael.
Since day one I've had quite short battery life of the phone - something between 24 to 36 hours (including standby and very moderate use).
In an attempt to find out the reason, I've installed a few programs which monitor the phone's current consumption, battery voltage etc.
Making long story short - all programs indicate that the phone's current consumption is ~56-60mA in standby mode. Thus, 1350mAh battery should last for 1350/60 = 24h.
That far everything makes sense. However, I've looked for methods to reduce the current consumption, either by downclocking the CPU, by turning off all radios, removing all skins and programs running in normal mode etc.
No luck - the current consumption just won't move.
It doesn't make much sense that turning off all radios, turning off the screen, turning off all programs etc. won't reduce the power consumption by even a fraction (depending on the SW/HW metering ability, of course).
Another strange behavior of the battery is that the battery indicator does not change for quite some time, and then drops by 3-4% in a very short time (~1 minute). I've seen this phenomenon in several monitoring programs, regardless of the updating time of the program.
Has anyone figured a way to reduce power consumption in standby mode?
What about downclocking?
Does anyone know what is the current consumption on other longer lasting battery time HTC phones?
Yuval.
disabling 3G normally saves battery.
did you make tests while in 3G or 2G?
I would like my battery to last longer.
FYI- I dont need a monitoring program to tell me that wifi, data, and bluetooth visibility kill my battery...
Battery test conditions
Note that the 56mA current consumption is with all radios closed!! (alternatively only with 2G GSM on - no 3G, no WiFi and no BT).
The point is to reduce the amount of current drawn from the battery in standby mode.

Do you have the nuePower battery driver? I've heard that its not very accurate.
It's weird that you are looking for a way to extend the battery life as it is clearly stated that the battery lasts for about up to 419 minutes of talk time (about 7 hours). So, no matter what you do, that is the maximum. Please note that the 7 hours does not included standby time. Regarding standby mode, no use to play around with it as if you put your device in standby mode, it will last 367 hours. Of course, without even waking it up even for a moment (after a full recharge).
Running battery monitoring program normally makes thing worse as some do not allow the device to truely enter standby mode. Also, note that some 3rd party applications also cause that, for example S2U2 (version 1.40 seems to fix the problem). Plugging in the earphone (via the usb port) also does not let the device to truely enter standby mode. The easiest way to test is to play some music and press the power button. If the screen turns off and the music stops, then it is in standby mode. If not, then the device is does not truely enter standby mode, and it consumes power (but lesser than when it is awakes).
In other words, no matter what you do, the battery lasts 7 hours of usage. So, the only way to extend the battery life to is purchase an extended battery (1800mAH) for Touch Pro. It will make your device thicker though.
When all the lab/field tests are done, one of the tests is to measure voltage drop with a Scopemeter/power analyzer. All we did was put the STOCK device in standby, took the back cover off and measured voltage draw with a Scopemeter/power analyzer . That would be the most accurate means of testing. The Scopemeter I use is a fluke 225c. With a Fluke 43b power quality recorder. the max over a 36hr period in standby was a 24.9mh draw. the lowest recorded was 12.1mh draw. The average was 19.3mh. You could also do this with a basic DMM.
I should also note this was done with ALL radios off.

Battery Drain Solution.
Travis Antonio Solutions.
Hello my Friends.
Normally my Pre Plus on Idle mode from 12.00 AM to 3.00PM consumes 10%, Really I don't know how much I consume using it for play and calls, but I charge it every 3/4 day (6+6+6 Hours=18 Hours) Of use till my Battery drains completely. I have the next installed:
Patches: 38
App Installed: 34
Linux App: 13
Web Server running over 3G.
AV Harrier II: at Power Up Over-voltage 1.005Ghz
Bright solution:
This is most of the drain of the Battery sol. you should put this less than 40%, The Pre-/+/2 /Veer has Better bright than other Devices even in 20% tested by myself.
IM Solution:
Do not use the Stock IM because is like bugged or something like that, makes the battery drain 7% than normal drain.
Email Solution:
Receiving a mail every time you get it is not so good for the battery because is always attempting to the server, the solution for this is get Mail manually or every day.
Bluetooth and GPS:
Really I don't see much use for Bluetooth since on WebOS can not do File Transfer, but WebOS 2.x made a change and now we can use Keyboards, avoid turn the Bluetooth if you're not using it, and GPS turn it off, is other core of Battery Drain, just turn it off if you're using it and when you're done, OFF.
WiFi and 3G
Really I haven't see difference between two of this because really the 3G consumes more than WiFi but only if you're using the things I said before
Airplane mode, I never tested this but some people says that Battery drain less if you use this mode when you're going to sleep.
Hope this was helpfully,
Thanks and have a good day
I have a Mi2S and I'm running the latest stock ROM 4.4.23.
Ever since the 4.4.11 update I've had poor idle battery life.
Before that when I look at my battery usage, as long as I have good signal and the screen is off, the battery level graph is flat.
Now, almost always when my phone is idle, no matter what there is some heavy drain, it was approximately 25% over 12 hours.
I've tried all the MI2S updates since then and they are all having this issue. I have not installed any new apps or changed anything on my current ones.
Attached are some wakelock detector screenshots.
Sometimes 小米服務 has many wake alerts, but sometimes it does not. Weather app is disabled, and autosync is disabled too. Occasionally 小米服務 does not have many wake alerts but that doesn't seem to reduce idle power draw, and I think it had this many wakes before as well.
Also the 3h wakelock app is the music player; the idle drain happened when the music player was off.
Thanks for reading.
Bump...
So I spent a night in airplane mode, and voila! 3% drain over about 12 hours!
I'm still trying to figure out exactly what it is, but whenever I get the chance to I'm going to spend another night in airplane mode with wifi on.
Bump...
There is a nice little utility app called power tutor, which shows you exactly which app drains your device. Maybe the problem isn't rom related...
You can find it on the play store.
Hi,
I have a question regarding battery life of the OPO. I'm still not sure whether I have a defective battery, or some apps drains my battery like crazy (or both?). I hope you can help me with this.
In the first 2 weeks since I got it, I use my OPO for mid to heavy activities (a lot of Whatsapp, Youtube, streaming music, etc). I always start the day with 100% battery and I thought it was normal to see the battery drops to at least 20% at the end of the day. To be honest, I didn't check the battery stats in Settings even once in this time frame, and due to my heavy usage, once again I thought this was normal.
Until one night I decided to plug the charger earlier than usual, unplug it around 11pm (w/ 100% battery), then I fell asleep. I was shocked the next morning (8am) when I saw the battery has decreased to 65% with no activities whatsoever. I check the battery usage in Settings and then saw Google Play Services (GPservice) at the top of the list with 45% usage, with "keep awake" time almost identical to total time on battery. I did some research and found some advice including 1) denying GPservice abilities to "keep awake" and "wake up" via privacy guard (from this thread http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525), 2) turn off location, 3) turn off sync, but none of them seems the solution to my problem. Since then, I always check the battery usage and reset it, to see if GPservice still at the top. Sadly it still there. After I reset the stats, go to sleep directly and check it about 1 hour later, GPservice uses 40% - 60% of the battery usage, draining about 6% battery / hour.
With screen on a few minutes, it easily drops to 5th or 6th place with ~7% usage, with screen and main apps I use on the 1st and 2nd place. When I googled about this using Firefox, that's when I start worrying about something else, the battery itself. With wi-fi and low brightness (less than >20% if I convert it from the slide bar), browsing with Firefox decrease the battery 1% in 2-3 minutes, no or low usage drains 1% in about 5-6 minutes. In contrast, charging increase the battery 1% in 1 minute. Is that normal? IDK, usually bad battery increasing faster when charging and decrease significantly when in use.
Please help, especially about the excessive GPservice battery usage. And if it's possible, I prefer non-root solution for it. Thanks and sorry for my bad English.

Definitely sounds like somethings not right, what apps do you have that access or could potentially access your location? If you're still not having any luck, as a last resort you could try a fresh install of CM11S and install your apps one by one to see if you can determine if any are responsible for sucking battery.
Give the below app a try:

Install Gsam to see if you can gain any more insight into whats causing battery drain.

CMIIW but I read somewhere that GServicefix does the same like privacy guard, denying some service to keep awake, wake up, etc.
So I installed Gsam and run it about 1 hour. Interestingly in there, Kernel (Android OS) is on the top the % list with 60% usage (mostly phone in idle/sleep). When I switch sorting to Kernel Wakelocks, it shows event0-798 & event2-798 as the top 2 wakelocks with around 7000 wakelocks. I'll update in few hours, thanks.

Hi, sorry for the late reply.
It seems reboot the phone a few times solves the problem. Battery usage now seems normal when idle, even with location & sync turned on.
I found airplane mode with Wifi on consumes a lot of battery (standby with screen off).
Below is the battery drop of one night (about 7 hours), using the latest official rom [G920FXXU2COH2] for G920FD.
- Case 1
Turn the phone into airplane mode and turned on the WiFi. About 50% battery drop for one night.
- Case 2
No airplane mode. Both WiFi and mobile networks are connected. About 3% battery drop for one night..
I don't know why this happens. Can anyone confirm that and tell me the cause to the battery drop. Is this a baseband problem?
Probably there is some app connecting to internet and because of Airplane mode it causes massive wakelock.
Could you post some wakelock stats by gsam or wakelock detector?
^^^ This. You need to find out what's causing wakelocks on your phone. It's probably an installed app.
It's possible you're running too many unnecessary apps in the background. Try searching on xda for this app called Purify. It showed I was running 17 unnecessary apps that I didn't use frequently. It needs root but it works magic. Let me know what you think. Btw it's not my app. Just something I stumbled on, on my search to save my battery life. I gained about 1 to 1 1/2 hours of screen on time. I have about 300 apps on my phone and I'm a rooted power user.
Oh, my phone used to lag from time to time when trying heavy multitasking. Not anymore. To each his own.
