Battery Drain Problem

Dear all.
I have a problem with the battery life time.
When I remember correct with my first FW 0.9.05 I had a lifetime of more than three/four days. Right now with the newest FW 0.9.37 (also with FW 0.9.27) I am only able to work two days without charging!
STRANGE:
The usage is described with ~6 hours and the standby mode with ~8h since last full charge. But I only used the phone 1h maximum in this 8 hours. How can this be? Do have also strange readings in your Usage display (--> Settings)? How can I really get my Meizu to more than 3 Days Battery life time? What tools / Programms run in the background which consume as much power, while the mobile phone should rest in the standby state? Please I need help (or a new Battery )
Thanks already for your replies!

if you run M8Notify....refresh...how many task are running?

With m8notify it shows a lot of inactive (off) alarms reminders from my calendar. These should not drain the battery or? I just installed the FW 0.9.0.5. I will test the battery life time from fully loaded and the consumption after one day... I am looking forward to know if the battery lasts longer. Perhaps they tuned via software/FW the processor speed so the power consume of the CPU is higher, even in idle state? Also what I observed is that when I start the phone with headphones pluged in, I hear some noise. it stops when I start the music player the first time. But this indicates also that there is some output through the audio device without any reason. I hope there is also more input from the other Meizu users, so perhaps they can show there configuration, for which there is a battery lifetime of more than two days! Thanks a lot ! Greetings, Morpheus!

I will be following this thread with interest. I and a Chinese colleague recently purchased M8SE's with FW 0.9.3.7. installed. I have installed several English version applications from this site whilst he has installed a similar set of Chinese versions from the m8fans site. Not sure if that is relevant or not however my battery up to last weekend was lasting no more than 12 hours with little use. I read all the battery related threads here and noticed somehwere that wi-fi can be a heavy drain so on Monday I disabled wi-fi and GPRS. With a full charge at 06:00 there was now 55% by 22:00, a significant improvement. I was thus convinced that wi-fi was the problem (even though no wi-fi activity was used) until I discussed with my Chinese colleague today to find that he still had 90% battery after 10 hours, with wi-fi and GPRS enabled, and he is easily achieving more than two days battery life. I hope to see some suggestions from other users but otherwise my next step is to start unloading applications.

Try this:
Run M8Notify....refresh...
how many task are running?
Then try cleaning
how many task are running now?
Is the battery life time improving after this procedure?
Minimize the brightness of the screen.
Perhaps turn of the light sensor, I think this is also consuming some energy...
in the internal settings (Windows CE Settings) you can reduce the time for sending the device into rest state (when it is not in use).
I hope you will have some success.
Bye,
Morpheus
Please write the number of task, which are running...

So dear forum. I remembered correct! With FW 0.9.0.5 the battery life time is much higher than with newer FW > 0.9.2.7. So everybody which wants a longer bat.-Lifetime and can abandon the newer options in the upgrades should think about going back to the old FW. I will also incremently try to find out when the power consumption problem occurs...
I think they speeded up the CPU in the newer FW on the software side (as you can do with laptops, in the power saving modes). The sliding effect of FW 0905 are not terribly fast compared to the FW >0927. What do think?
Bye and greetings!

Yesterday with wi-fi and GPRS enabled battery was expired after 12 hours. Today with wi-fi and GPRS disabled still have 60% after 12 hours (with higher usage too). Regarding the M8Notify data I have today 26 items, 16 of which are Red (presumably for deletion if I select clean up), 2 Green and 8 Black. I will clean up tomorrow morning.

Dear Forum,
I found the following, I have to correct myself for the last post concerning the lifetime of a battery with FW 0937:

Now, also with the newest official FW 0.9.3.7. I got a relative long battery life time of a more than 3 days (fully charged Friday morning -> today monday still ~45 % left). I monitored it with the m8test tool and read out the voltage: so I started with 4.179V (= 100%) and up to right now I have 3.752V (=45%) after three days! The daily use included a bit phoning, listening to mp3, so less usage perhaps than normal user are dealing with. But nevertheless I wanted to check out the Standbytime of the device. I think one has to do the following small "modifications" to the Meizu M8 to get this bat.lifetime:

- Install the FW upgrade
- install MPTest (to monitor the voltage, if you like)

1. go to settings - Brightness: turn of the ambient light sensor, set brightness to minimum (0)

2. goto power properties (control.exe in the windows folder on the device --> Power.) set all values under Schemes to minimum values (--> 1 minute)! I think this is most important!

3. after installing all tools (I didn't install much) / alarms / calendar settings RUN THE m8notify tool Refresh / Clean up to cancel out all non important operations.

Please let me know if this works also for your device improving battery life time! Thanks in advance!

My M8SE was bought in Beijing 4 weeks ago and was pre-installed with hopefully the official FW 0937. Is there an updated 0937 available and if so where could I find it? I'll try your suggested energy saving tweaks anyway.

just check the firmware download section for the newest FW.

I notice a change after a few minutes dealing with battery temp and cpu
usage.

good tips..

A change for the better or for worse?

It seems a little better. My phone has been in standby since I posted earlier. I was at about 90 percent cap. After 12 hours I only dipped 3 percent I will put in standby til tomorrow and check again.

I think the main thing is changing the brightness of your backlight. Before I would leave the brightness alone because I can see the screen perfectly fine and battery life was great. For some reason when I was on FW 9.2.7 I changed the back light setting and instead of my phone battery lasting 2-3days it lasted not even 6 hours.

Being that I knew the problem as soon as it a rised I tried to turn the back light back down manually but the battery still did the same thing (be flat within the day).

So what I did to solve this problem was Restored my back up files and it went back to normal.

Alternatively you could just update your FW and not restore your old brightness settings

Also important is to send the device in standby mode by choosing standby in the suspend assistant tool: in this case there will be no time delay (1minute like in the power settings --> Windows ce <-- of the device) before going to standby mode!

Hi Forum,
what I observed yesterday night up to this morning was the following:
I inserted the Dual sim card adapter.
I had a drop of 15% battery capacity (100%-85% corresponds to ~ delta U = ~200mV). So there is also an increase of power consumption when using the dual sim adapter... Although my mobile phone was in flightmode... Thats strange. Normally I send my phone in Standbymode using suspend assistant... The next time after hours I check the standbytime/Start up Time with this nice tool, I see no big difference (if I am not using the device a lot). So this indicates me that the phone was send to standby correctly. While from yesterday to this morning a comparison showed me different numbers, so my phone was not in standby mode the whole night as it should be.
I don't know exactly if it is a problem of the hardware (dual sim adapter) or from the software side... Right now, I assume that it is the dual sim adapter.
Greetings,

Hi Morpheus,
it sounds a bit obvious cause you would be charging 2 sims instead 1.
On the otherhand a difference in FW could be explaining to problem to.
example:
android build is not yet completly optimized, so this one for example could drain a battery in a few hours instead of days. Once optimized it could last a few days.. so this story is the same with the original os..

Using Morpheus settings above, except screen brightness set at 20%, plus wifi and GPRS disabled my phone lasted from a full charge at 06:00 yesterday and shutdown at 16:00 today (34 hours) with light usage.

I´will try this too...seem to be a very good idea!! Thanx

great, my battery is still very good, 95% power, using for 7 hours now.....
I did this....
